[0017] An embodiment in which the present invention is applied to a coaxial type electrical connector, which uses a coaxial thin-wire cable as a signal transmission medium, will be explained in detail hereinafter on the basis of FIG. drawings. [0018] [About the overall structure of the coaxial type electrical connector] Firstly, a plug connector 10 serving as a coaxial type electrical connector according to a first embodiment of the present invention shown in FIGS. 5 is configured to be connected to an end portion of a thin-wire coaxial cable SC serving as a cable-shaped signal transmission medium and configured to be matched so as to be inserted from the upper side on an associated electrical connector (illustration omitted), which consists of a receptacle connector or the like mounted on or removed from a predetermined printed wiring substrate omitted from the illustration. The operation of matching / removing the plug connector 10 with / from the associated electrical connector (receptacle connector or the like) is in a direction approximately perpendicular to the plane of the printed wiring substrate. More specifically, a connector main body portion constituting a main corresponding portion of the plug connector 10 is formed to have a cylindrical shape as an approximate shape; an end portion of the fine-wire coaxial cable SC is connected to the connector main body portion, which is approximately cylindrical in shape, from a direction of a radial direction outer side; and, in the state in which the fine-wire coaxial cable SC is connected, the plug connector 10 is arranged to face a position above the associated electrical connector (receptacle connector or the like). Then, when the entire plug connector 10 is moved down to the direction approximately perpendicular to the outer surface of the printed wiring substrate, a lower end portion of the plug connector 10 is brought into a state in which it is in correspondence with an upper end portion of the associated electrical connector.
    [0002] When the plug connector 10 is brought into the correspondence state in which it is inserted in this manner into the associated electrical connector from the upper side, the end portion of the thin-wire coaxial cable SC is connected to an electrically conductive passage. The wiring pattern on the printed wiring substrate is via the plug connector 10 and the associated electrical connector. Here, the direction in which the plug connector 10 is inserted on the associated electrical connector (receptacle connector or equivalent) is assumed to be the "down direction", and, opposite it the direction in which the plug connector 10 is removed is the "upward direction". In the plug connector 10 itself, an edge portion to which the end portion of the thin-wire coaxial cable SC is connected is assumed to be an "edge portion of the front side", an opposite edge portion of the latter is assumed to be an "edge portion 15 of the rear side", moreover, the direction from the "edge portion of the back side" to the "edge portion of the front side" is assumed to be the "direction towards the "connector front", and the opposite direction to it is assumed to be the "rearward direction of connector". In addition, the direction perpendicular to both the "up-down connector direction" and the "front-to-back connector direction" is assumed to be the "left-right connector direction". [0021] [With regard to the coaxial cable] As is more particularly shown in FIG. 6, in the fine-wire coaxial cable SC serving as a cable-shaped signal transmission medium, a central cable conductor (wire of signal) SCa and an outer cable conductor (shield wire) SCb, which are formed by a plurality of conductive wires, are configured to be coaxially stacked via a dielectric cable body SCc, the outer conductor Cable (shield wire) SCb among these is caused to be in an exposed state by removing an outer circumferential cladding material SCd, and the central cable conductor (signal wire) SCa is made to be in a state. exposed by further removing the outer cable conductor (shield wire) SCb and the dielectric cable body SCc. A signal circuit is formed when the central cable conductor SCa, which is arranged to be along the central axis of the fine-wire coaxial cable SC, is connected to an internal conductor contact (element 10). signal contact) 12, which is fixed on an insulating housing 11. The outer cable conductor SCb, which is arranged to surround the outer circumferential side of the central cable conductor SCa, is connected to an outer conductor body 13a of a shielding body 13, and, when the outer conductor body 13a functions as a contact element for grounding, a ground circuit is configured to be formed. [0023] [About the insulating housing] Here, as shown in FIG. 5, the insulating housing 11 described above comprises an insulating main body portion 11a having approximately a disk shape, which constitutes the part of connector main body serving as the main corresponding part, and, at a lower portion of the insulating main body portion 11a, comprises integrally an insulating insertion portion lib inserted on the inner side of the electrical connector. (receptacle connector or equivalent) which is the corresponding associated part. Among these, at an approximately central portion of the insulating main body portion 11a, the end portion of the thin-wire coaxial cable SC described above, and the inner conductor contact (signal contact member) 12 on which the central cable conductor (signal wire) SCa of the thin-wire SC coaxial cable 3032069 12 is to be placed are fixed on the part which is formed in a recessed form at an approximately central portion of the upper surface of the main insulating body portion 11a. The outer conductor body 13a of the shielding body 13 serving as a ground contact is attached to the insulative main body portion 11a described above so as to surround the periphery of the inner conductor contact 12 described above. from the outer side. On the other hand, a cable support portion 11c (see Fig. 7), which consists of a recessed groove forming an approximately semicircular shape in a front view, is formed at the edge portion of the front side. of the insulating main body portion 11a, 15 and the end portion of the fine-wire coaxial cable SC described above is configured to be placed on and received by the wall surface of the inner side of the cable support portion 11c. Furthermore, an insulating pressure plate 11 comprising a tongue-shaped element is provided in one piece with the insulating main body portion 11a of the insulating housing 11 described above so as to cover the central conductor. cable SCa of the fine-wire coaxial cable SC from the upper side.
    [0003] The insulating pressure plate 11d is formed by a long thin flat plate-shaped member which forms a cantilevered shape from an edge on the side of the rear connector end of the housing portion. insulating main body 11a and protrudes so as to be disposed along the fine-wire coaxial cable SC, and in an initial state before the end portion of the thin-wire coaxial cable SC is placed more particularly as shown in FIG. Figure 12 in Figure 14, the insulating pressure plate 11d is in an open state in which it is raised to the upper side. Then, once the end portion of the fine-wire coaxial cable SC is placed at the insulating housing 11, the insulating pressure plate 11d is folded to the underside with a body cover portion 13b, which is provided in the shielding body 13 as described later, and the portion extending to form a flat plate shape from a folded portion 11f, which is formed in this process, is arranged to be covered since 10 the upper side along the fine-wire coaxial cable SC. Here, in an area on the base side of the insulating pressure plate 11d, which extends to form the cantilevered shape as described above, there is provided a void portion. 11e comprising a through hole which extends into a long thin shape along the extension direction of the fine-wire coaxial cable SC. At an approximately central portion of the insulating pressure plate 11d in a width direction, which is perpendicular to the extension direction 20 of the coaxial thin-wire cable SC, the void portion 11a is formed by the an inner wall of a groove (a through hole in the present embodiment) recessed in a bearing-like manner relative to the surface of the insulating pressure plate 11d in a plate thickness direction. As shown in Fig. 15 and Fig. 16, when the insulative pressure plate 11d is folded toward the lower side and disposed in the upper side of the fine-wire coaxial cable SC, the vacuum portion 11e described above is disposed at the level of the insulating pressure plate 11d, and an air layer formed in a long and thin shape by the inner wall surfaces of the void portion 11e is configured to be arranged to face, from the upper side, at "a wire connection portion", which is an area of electrical connection of the central cable conductor (signal wire) SCa and the inner conductor contact 12. [0027] The vacuum portion 11e, which comprises the opening hole as described above, is disposed in the radially inward direction of the outer conductor body (mass contact element) 13; as shown particularly in FIG. 4, a hole size W1 in a width direction (the direction perpendicular to the extension direction of the fine-wire coaxial cable SC) of the vacuum portion 11e is formed to be smaller than a dimension of an outer width-wise shape W2 of an upper bar portion (tongue-shaped portion) 12a, which forms a part of the internal conductor contact described above (contact element of signal) 12 (W1 <W2). The structure of the upper bar portion (tongue portion) 12a of the inner lead contact 12 will be explained later in detail; it is structured to form the "wire connection portion" with respect to the fine-wire coaxial cable SC when the upper bar portion 12a, which forms the tongue-shaped portion, is in contact with the fine-wire coaxial cable SC with pressure from the upper side. [0028] According to the width value relation (W1 <W2) presented by the void portion 1le relative to the upper bar portion (tab-shaped portion) 12a of the inner conductive contact 12, when the insulating pressure plate 11d is in a relationship such that the 11d insulating pressure abuts against the inner conductor contact 12 when folded towards the lower side, thanks to this, the elements 11d and 12 are both configured to be folded in one piece.  Here, particularly as shown in FIG. 5, the vacuum part lie, which is provided in the insulating pressure plate 11d in the manner described above, is disposed in a state in which the void portion faces from the upper side to the "wire connection portion" serving as the electrical connection area of the central cable conductor (signal wire) SCa of the thin-wire coaxial cable SC and the contact of internal conductor 12, further extends from the position facing the "wire connection portion" to the base side of the insulating pressure plate 11d, which is the rear connector side, extends so to be bent along the folded portion 11f formed in the insulating pressure plate 11d, and then extends to the underside.  On the other hand, with respect to the insulating main body portion 11a of the insulating housing 11 constituting the main corresponding part comprising the insulating pressure plate 11a, the insulating insertion portion 11b comprising a cylindrical shape approximately The hollow core protruding from the insulating main body portion 11a to the bottom side is configured so that the underside of the insulating insertion portion 11b is inserted into the inner side of the associated electrical connector (connector 11a). receptacle or equivalent) serving as an associated part as described above.  [0031] [On the subject of the shielding body] Furthermore, as shown in FIG. 10 and FIG. 11, the outer surface of the insulating housing 11 having the insulating main body portion 11a and the insulating insertion portion 11b described above is covered by the outer conductor body 13a, which constitutes the main corresponding part of the shielding body 13 comprising a thin metal plate member.  The outer conductor body 13a constitutes the mass-contacting member having an approximately hollow cylindrical shape formed to substantially annularly cover the insulating main body portion 11a of the insulating housing 11 from the radially outer side.  A lower portion of the outer conductor body (ground engaging member) 13a is formed into a body inserting portion 13a, which annularly covers the insulative insertion portion 11b described above from the outer side of the body. radial direction, and the body cover portion 13b covering the upper surface side of the insulating main body portion 11a described above is operably / openly connectable to an annular opening portion of the upper end of the outer conductor body 13a.  Here, in particular as shown in FIGS. 7 to 12, the shielding body 13, which is in the initial state before the end portion of the thin-wire coaxial cable SC is connected and fixed, is in a state in which the body cover portion 13b is open to the upper side with respect to the outer conductor body 13a described above.  In other words, the body cover portion 13b in the initial state is disposed at an edge portion of the rear side of the outer conductor body 13a so as to be lifted to the approximately vertically higher side by via a connecting member 13b1 comprising a narrow plate-shaped member.  In addition, at an inner cover surface of the body cover portion 13b, in other words, at the surface positioned in the inner side when the body cover portion 13b is closed, 3032069 the insulating pressure plate 11d comprising the tongue-like member raised from the insulating main body portion 11a of the insulating housing 11 to the upper side is disposed to be along the interior concealment surface of the portion body cover 13b.  It should be noted that the installed position and the installed number of the connection element 13b1 can be arbitrarily chosen.  In the open state (initial state) of the shielding body 13 as described above, once the end portion of the thin-wire coaxial cable SC is set up so as to be received by the cable support portion 11c of the insulating housing 11, when the body cover portion 13b of the shield body 13 is pushed down to an approximately horizontal state such that the connecting member 13b1 is folded approximately at right angles to the insulating pressure plate 11d towards the lower side, it follows that the entire insulating main body portion 11a of the insulating housing 11 is covered by the body cover portion 13b from the upper side, and the body shield 13 takes a closed state.  In this case, the body cover portion 13b has a cover structure such that when the body cover portion 13b is pushed down to the approximately horizontal and closed condition as described above, the body cover portion 13b covers the annular opening portion on the side of the upper end of the outer conductor body 13a; A front cover portion 13b2, which in particular covers the cable dielectric body SCc and the outer cable conductor (shield wire) SCb of the thin-wire coaxial cable SC from the upper side is continuous in one piece up to at a portion of the front side of the 3032069 body portion 13b, which is pushed down to the approximately horizontal state.  The front cover portion 13b2 is configured to cover a pair of cable shield arms 13a2 and 13a2 protruding from the outer conductor body 13a described above to the front side from the outer side with the coaxial cable at fine wire SC.  In this case, the cable protection arms 13a2 and 13a2 described above are configured to extend along the two left-right directional sides which encircle the fine-wire coaxial cable SC, and the arms The mating pairs are provided so as to protrude from the edge portion of the front side of the lead body 13a described above to the front side so as to be opposite and approximately parallel to each other along the portion. end of the fine-wire coaxial cable SC.  In addition, at the two edge portions of the front cover portion 13b2, which is provided to protrude from the front side of the body cover portion 13b in the manner described above, first fastening retaining plates 13b3, second securing retaining plates 13b4, and third retaining retaining plates 13b5 comprising a pair of tab-shaped members are provided to form flange plate shapes.  Of these, the first attachment retaining plates 13b3 are configured to be folded and crimped to cover the fine coaxial cable SC and the cable protection arms 13a2 and 13a2.  In other words, the flange plates on both sides constituting the pair of first attachment retaining plates 13b3 and 13b3 are arranged to be positioned on the outer sides of both sides of the cable protection arms. 13a2 and 13a2 when the body cover portion 13b is pushed down to the approximately horizontal state and is bent to the connector inner side along the outer wall surfaces of both sides of the protection arms 5 of cable 13a2 and 13a2 so as to perform crimping from this state; as a result, attachment of the body cover portion 13b to the outer conductor body 13a is performed, and in particular the cable dielectric body SCc of the thin-wire coaxial cable SC is attached to the cache portion of body 13b.  Furthermore, the second fastening retaining plates 13b4 and the third fastening retaining plates 13b5 are provided so as to be adjacent and juxtaposed to the front side of the first fastening retaining plates 13b3 described above and are formed by comparatively small flange plates.  Second securing retaining plates 13b4 and third retaining retaining plates 13b5 are configured to be folded and crimped to cover the outer cable conductor (shield wire) SCb and outer circumferential cladding material SCd of the cable SC coaxial cable from the outside.  In other words, when the body cover portion 13b is pushed down to the approximately horizontal state, the flange plates on both sides constituting the second attachment retaining plates 13b4 and the third attachment retaining plates 13b5 are disposed at locations in the outer sides of both sides of the outer cable conductor (shield wire) SCb and outer circumferential coating material SCd of the thin-wire coaxial cable SC and from this state, are bent towards the inner connector side so as to perform crimping.  As a result, the body cover portion 13b is secured against the outer cable conductor (shield wire) SCb and the outer circumferential coating material SCd of the thin-wire coaxial cable SC, and the outer cable conductor SCb contacts the second securing retaining plates 13b4, thereby forming a ground circuit by virtue of the shielding body 13.  On the other hand, the body insertion portion 13a1, which constitutes the lower side portion of the shielding body 13 as described above, is configured to be externally in correspondence with a portion of the radial direction outer side of the associated connector (receptacle connector or equivalent), which is the corresponding associated part, and constitutes a connector coupling portion with the insulating insertion portion 11b of the insulating housing 11, which is to be inserted into the radial direction inner side described above of the associated connector.  More specifically, the body inserting portion 13a1 is formed to have an approximately cylindrical shape, and a coupling engagement portion comprising an annular recessed groove which protrudes toward the radial direction inner side is formed in a portion. lower end of the insertion side of the body insertion portion 13a1.  Once the body cover portion 13b is pushed down to the approximately horizontal state in the manner described above, the coupling engagement portion is configured to be in a correspondence relationship in a manner that is substantially the same. resilient with respect to a coupling blocking portion (omitted illustration), which is provided at the associated connector serving as a corresponding associated part.  [0041] [About the signal contact element] The internal conductor contact (signal contact element) 12 used in this embodiment is attached to the insulating main body portion 11a of the housing. insulation 11 described above, for example, by press-fitting or insert molding, at a cable-clamping portion having a pair of upper / lower bar portions 12a and 12b to be connected to the cable center conductor ( signal wire) SCa of the fine-wire coaxial cable SC, and is configured such that resilient spring portions 12c are provided to extend from the lower bar portion 12b of the cable clamping portion to the lower side come into elastic contact with an electrically conductive contact (illustration omitted) provided at the corresponding associated connector (receptacle connector or equivalent).  [0042] The upper bar portion 12a and the lower bar portion 12b constituting the cable clamping portion are formed by a continuously extending web-shaped member and have a clip bar structure (or clip) formed to be folded to form an approximately C-shaped or approximately L-shaped shape in a side view.  They are structured to form the "wire connection portion" cited in the present invention by clamping the central cable conductor (signal wire) SCa of the thin-wire coaxial cable SC between the two bar portions 12a and 12b since the upper and lower sides in the manner of a staple by folding and deforming the portion connecting them both in the direction in which the upper bar portion 12a approaches the lower bar portion 12b in a manner described further later.  Here, in the initial state which is a step before the end portion of the fine-wire coaxial cable SC described above is connected, the upper bar portion 12a of the cable clamping portion is formed. to form a tongue-shaped portion raised to an oblique upper side as shown particularly in FIGS. 7 to 9 and is in a state separated from the lower bar portion 12b on the upper side since the portion An upper bar member 12a serving as a tongue portion is in an open state on the upper side.  On the other hand, the lower bar portion 12b of the cable clamping portion is formed as a cable-laying part on which the cable center conductor SCa of the coaxial end-wire cable SC needs to be formed. positioned and extends approximately horizontally from the connected portion to the upper bar portion (tab-shaped portion) 12a toward the front connector side.  When the end portion of the thin-wire coaxial cable SC is placed on the cable support portion 11c of the insulating housing 11 in the manner described above, the cable center conductor SCa of the thin-wire coaxial cable SC is placed on the surface of the lower bar portion 12b of the upper side cable clamping portion.  Once the end portion of the fine-wire coaxial cable SC is placed on the cable support portion 11c of the insulating housing 11 and brought into a state determined in this manner, the body cover portion 13b of the body shield 13 is pushed down to an approximately horizontal state with the insulating pressure plate 11d described above.  In this process, the upper bar portion (tab-shaped portion) 12a of the pushed cable clamping portion 3032069 23 to the lower side by the insulating pressure plate 11d is bent and deformed so as to be pushed downwards. to an approximately horizontal state, and the upper bar portion 12a is configured to press the cable center conductor (signal wire) SCa from the upper side as shown particularly in FIG. 5.  Here, an intermediate position in the extension direction of the upper bar portion 10 (tab-shaped portion) 12a constituting the cable clamping portion described above is formed in an electrode portion on the opposite side. upper, which presses the central cable conductor (signal wire) SCa from the top side.  The upper side electrode portion 15 provided on the upper bar portion 12a of the signal contact element 12 is formed in a folded form which protrudes in a downward direction to clamp the thin-wire coaxial cable SC and an inner-folded shaped portion is formed into a projection-shaped contact portion which protrudes to the coaxial fine-wire side SC.  When the body cover portion 13b is pushed down to the approximately horizontal state as described above, the protruding contact portion is configured to engage from the top side with pressure, with the central cable conductor (signal wire) SCa of the fine-wire coaxial cable SC placed on the bottom bar portion 12b, the central cable conductor (signal wire) SCa is clamped into a state of contact with pressure between the two bar portions 12a and 12b, and an electrical connection is configured to be established.  The electrical connection zone in which the central cable conductor (signal wire) SCa of the fine-wire coaxial cable SC is connected to the internal conductor contact (signal contact element) 12 in this manner is called "Wire connection portion" in the present invention as described above.  The lower bar portion 12b provided as a cable-laying portion of the inner conductor contact 12 described above is formed by a plate-shaped member which forms a flat shape and extends to front side from the portion connected to the upper bar portion 12a, which forms the tongue-shaped portion, and the lower bar portion 12b is fixed in a state in which it is placed on the upper surface of the body portion main insulator 11a of the insulating housing 11 described above.  At an approximately central portion of the lower bar portion 12b, a connection monitoring hole 12b1, which forms a round hole shape, is formed to penetrate through, and a connector contact insertion hole. The partner is formed to penetrate through the insulating housing 11 to form a shape approximately coaxial with the connection monitoring hole 12b1.  The contact insertion hole of the associated connector also serves as a connection monitoring hole, and the state of disposition of the central cable conductor (signal wire) SCa of the fine-wire coaxial cable SC can be visually verified from the lower side through the connection monitoring hole 12b1 described above.  Furthermore, the lower bar portion 12b of the cable clamping portion is formed by the strip-shaped member extending in the front-to-back connector direction as described above, the pair of resilient spring portions 12c and 12c extends integrally with a predetermined gap 3032069 therebetween from the edge portions of both sides in the plate thickness direction (left-right direction) from the lower bar portion 12b to the lower side, and an electrically signal-conductive (omitted) pin-shaped contact provided on the corresponding associated connector (receptacle connector or the like) is configured to be inserted into the between the two resilient spring portions 12c and 12c in a state of pressure contact and to be electrically connected thereto.  Here, when the body shield portion 13b of the shield body 13 which is in the open state of the upper side in the initial state as described above is pushed downward to the lower side the insulating pressure plate 11d which is also in the open state of the upper side in the initial state is opposed to a predetermined area of the inner cover surface of the lower side body cover portion 13b and fed into the a state of pressure contact, and the insulating pressure plate 11d is then pushed down to an approximately horizontal state with the body cover portion 13b.  Then, the body cover portion 13b and the insulating pressure plate 11d are disposed in a laminated form in the upper side of the central cable conductor (signal wire) SCa via the upper bar portion (part tongue shaped) 12a of the inner conductor contact (signal contact element) 12.  At this point, in the area opposite to the inner cover surface in pressure contact of the body cover portion 13b and the insulating pressure plate 11d, a groove portion recessed on the long and thin body side 14 is provided. so as to extend in the front-to-back direction of the connector along the cable-shaped signal transmission carrier SC.  The body-side recessed groove portion 14 in the present embodiment is configured to recess a portion of the inner surface of the body cap portion 13b into a bearing shape in the plate thickness direction. and an air layer formed by an inner wall surface of the body-side recessed groove portion 14 is in an arrangement relation in which the air layer is opposed to the air layer, which is formed by the vacuum portion 11e of the insulating pressure plate 11d described above, from the upper side.  Due to the arrangement relation in which the body-side recessed groove portion 14 and the vacuum portion 11e overlap in a mutually opposed state in the up-down direction, the air layers for adjusting the impedance of the transmission signals are formed in a state of overlap in the portion between the two elements 14 and 11e.  The body-side recessed groove portion 14 in the present embodiment is formed, for example, by press-work and is provided by reducing the plate thickness of the body cover portion 13b of the value of the groove depth of the recessed groove portion of the body side 14.  However, depending on the impedance matching value, there may be a case where the recessed groove portion of the body side 14 is not provided.  [0053] The recessed groove portion of the body side 14 extends along the cable-shaped signal transmission bracket SC as described above; the extension range in the longitudinal direction of the recessed body-side groove portion 14 is provided in a range from the coupling portion of the lower bar portion (cable-laying portion) 12b and the upper bar portion (tongue portion) 12a, which is the rear end portion of the inner lead contact 5 (signal contact element) 12, to the position above the portion at the level of the which the dielectric body SCc of the cable-shaped signal transmission medium SC is exposed.  [0054] More particularly, as shown particularly in FIG. 10 and FIG. 11, the body-side recessed groove portion 14 in the present embodiment is provided with a narrow groove portion 14a positioned thereon. above the wire connection portion which is the area in which the cable center conductor SCa of the thin-wire coaxial cable SC is electrically connected and a wide groove portion 14b is positioned above the dielectric body SCc of the coaxial cable SC end wire such that they are linearly continuous, and the groove width presented by the narrow groove portion 14a disposed at the wire connection portion, which is the electrical connection area, is formed of to be smaller than the plate width presented by the insulating pressure plate 11d described above in the electrical connection area.  The areas corresponding to both sides in the direction of the groove width of the body-recessed groove portion 14 are formed in the inner cover surface of the body-cover portion 13b, and the inner surface of the The cover of the body cover portion 13b positioned in both sides of the narrow groove portion 14a disposed at the wire connection piece described above is formed of fall prevention portions 13b6 which abut the 3032069. upper surface of the insulating pressure plate 11d from the upper side.  In other words, the fall prevention parts 13b6 are in a relationship in which the fall prevention parts 13b6 abut against the upper surface of the insulating pressure plate 11d, thus being stacked above the plate insulating pressure lld; the insulating pressure plate 11d therefore does not enter the narrow groove portion 14a, which is disposed in the electrical connection area of the air layer formed by the body-side groove portion 14 such that the groove portion recessed on the body side 14 is formed in the electrical connection area.  On the other hand, the groove width of the wide groove portion 14b is larger than the plate width of the insulating pressure plate 11d; however, the insulating pressure plate 11d in the present embodiment extends only to an intermediate position of the narrow groove portion 14a in the extension length direction and is configured not to be opposed to the wide groove portion 14b.  Therefore, even in the closed state in which the body shield portion 13b of the shield body 13 is pushed downward, the insulating pressure plate 11d does not enter the interior of the wide groove portion. 14b, and the insulating pressure plate 11d is retained in a stacked state in which it is in pressure contact with the inner surface of the body cover portion 13b along its entire length.  The state in which the body cover portion 13b is stacked above the insulative pressure plate 11d is maintained, and the body-recessed groove portion 14 is configured to be disposed at the immediately above the insulating pressure plate 11d.  The wide groove portion 14b, which forms the other zone of the recessed groove portion of the body side 14 slightly away from the wire connection portion serving as the electrical connection zone, is disposed at the level of the groove portion 14b. the position corresponding to the exposed portion of the dielectric body SCc of the fine-wire coaxial cable SC as described above, and the groove width presented by the wide groove portion 14b is formed to be slightly larger than the diameter outside 10 presented by the dielectric body SCc of the coaxial cable SC.  Therefore, the dielectric body SCc of the fine-wire coaxial cable SC is housed in the wide groove portion 14b of the recessed groove portion of the body side 14, and as a result the height of the connector is reduced.  The groove width presented by the wide groove portion 14b is intended to be larger than the plate width of the insulating pressure plate 11d as described above and is intended to be larger than the plate width of the internal contact 12 in the electrical connection area.  On the other hand, the groove width of the narrow groove portion 14a constituting a portion of the recessed groove portion of the body side 14 as described above is provided to be the same as or larger than the wire diameter of the central cable conductor (signal wire) SCa of the cable-shaped signal transmission medium SC, in other words, the part in contact with the internal conductor contact (signal contact element) 12.  In addition, the groove width of the narrow groove portion 14a constituting the other portion of the body-recessed groove portion 14 is provided to be smaller than the plate width presented by the upper bar portion 12a of the 3032069 30 internal conductor contact (signal contact element) 12.  According to the present embodiment having such a configuration, the void portion 11e formed by the inner wall surfaces of the through-hole provided in the insulating pressure plate 11d is disposed in the radial direction inner zone of the body of the outer conductor 13a of the shield body 13 and is in an arrangement relation in which it faces the wire connection portion which is the electrical connection area of the central cable conductor (signal wire) SCa and the contact of internal conductor 12.  Therefore, the air layer for impedance adjustment formed by the void portion 11e is arranged to face the wire connection portion in which impedance mismatch easily occurs, and the degree of adaptation (VSWR) impedance which is an important design element of an electrical connector is effectively adjusted; As a result, a transmission with good high frequency signals is easily maintained while a decrease in size or reduction in height of the electrical connector is achieved.  In particular, in the present embodiment, since the vacuum portion 11e provided in the insulating pressure plate 11d extends to the area which reaches the folded portion 11f of the insulating pressure plate 11d, the air layer for the impedance adjustment is also formed in the opposite portion to the outer conductor body 13a of the shield body 13 in the radial direction.  As a result, impedance matching is even more effectively achieved, and stiffness of the folded portion 11f of the insulating pressure plate 11d is reduced by the void portion 11e.  Therefore, a folding operation with respect to the insulating pressure plate 11d is easily accomplished without causing breakage, etc.  Furthermore, according to the present embodiment, in addition to an impedance matching action 5 by the vacuum portion 11e of the insulating pressure plate 11d, an impedance matching is also performed by the a body-recessed groove portion 14 provided in the body-cover portion 13b of the shield body 13.  Therefore, impedance matching is performed even more efficiently and easily.  When the void portion 11e is formed by a through hole such as the present embodiment, since the void portion is formed by the through hole which is easy to manufacture, the manufacturing efficiency is also improved.  A configuration of a second embodiment shown in FIGS. 17 to 19 will then be explained.  In the second embodiment, "1" which is the number of tens of references applied in the first embodiment described above is replaced by "2".  In a plug connector (coaxial type electrical connector) according to the second embodiment, a void portion 21e provided in the region in the base side of an insulating pressure plate 21d is formed by a groove of shape recess provided with a bottom extending in a long thin shape along the extension direction of the fine-wire coaxial cable SC, and the configurations of the other elements are similar to those of the first embodiment.  More particularly, the void portion 21e formed by the inner wall surfaces of the recess-shaped groove provided with a bottom according to the present embodiment is also formed so as to be recessed to form a shape. bearing in a plate thickness direction (upward direction) on a portion of the surface of the insulating pressure plate 21d; when the insulating pressure plate 21d is arranged to overlap with the upper side of the fine-wire coaxial cable SC, the recessed-shaped groove constituting the vacuum portion 21e is in a layout relation as it faces at the "wire connection portion" which is the electrical connection area of the central cable conductor (signal wire) SCa and an inner conductor contact 22 from the upper side.  The void portion 21e comprising the recessed shaped groove extends from the "wire connection portion (electrical connection area)" of the central cable conductor (signal wire) SCa and the inner conductor contact 22 to the the base portion side of the insulating pressure plate 21d in the rear connector side, extends to be bent along a folded portion 21f formed in the insulating pressure plate 21d, and then extends towards the bottom side.  In the second embodiment provided with the void portion 21e comprising such a recessed-shaped groove provided with a bottom, operation / effects similar to the first embodiment can also be obtained.  The invention made by the present inventors has been explained in detail above based on the embodiments.  However, the present embodiment is not limited to the embodiments described above, and it goes without saying that various modifications can be made in a range that does not deviate substantially from it.  For example, although the embodiments described above apply the present invention to electrical connectors of a vertically-matching type, the present invention can be similarly applied to electrical connectors as well. of a horizontal correspondence type.  [0068] The present invention is not limited to a connector for a single-core thin-core coaxial cable as the embodiments described above, but may be applied in a manner similar to connectors for a cable a coaxial connector disposed in a multipolar shape, an electrical connector of a type in which a plurality of coaxial insulating cables are mixed, etc.  [0069] As described above, these and above cable embodiments can be widely applied to different electrical connectors that are used in different electrical devices.
