    Best Mode for Carrying Out the Invention An outlet 10 according to one embodiment will be described below based on Figures 1 to 12. Note that in the drawings, identical means have been assigned identical numerals and a double description thereof has been omitted. In addition, the directions X, Y and Z are represented as a forward-backward direction and a width direction and a longitudinal direction, respectively, of the socket 10.
    All directions Z, Y and Z are indicated directions for drawings. However, the directions are not limited unless there is another explanation.
    As shown in Figs. 1 and 2, the socket 10 according to this embodiment includes a housing (first housing) 1, a housing section (second housing) 1a and a shaft section 1b. The second housing 1a has a connection insertion port 1a into which a plug 7; 2013-04-29 10 15 20 25 30 plug connection (not shown) is inserted. The shaft section 1b projects from a rear surface side of the second housing 1a, the rear surface side being opposite a front surface side into which the connection is inserted.
    The first housing 1 is formed integral with the second housing and the shaft section 1b (see Fig. 2). In addition, the socket 10 includes a door (first door) 2 supported rotatably on the shaft section 1b. The first door 2 includes a door section (second door) 2a which closes the connection inlet port 1a, and a through hole section 2c. Here, the through-hole section 2c means a first through-hole 2c of the first door 2. The through-hole section 2c and the second door 2a are arranged adjacent to each other. The through hole section 2c opens the connection inlet port 1a. The first door 2 When the connection is inserted into the connection insertion port 1a, the first door 2 is rotated about the shaft section 1b when the plug connection is inserted and the plug connection is inserted through the through-hole section 2c. The socket 10 also includes a body 4. The body 4 has a door support bearing section 4a. The door carrier bearing section 4a supports the first door 2 from a rear side of the second housing 1a and prevents it from falling from the first shaft section 1b. Furthermore, the socket 10 includes a spring 3 which biases the first door 2 axially so that the second door 2a closes the connection inlet port 1a. The spring 3 is arranged between the side 1 of the first housing and the side 4 of the body.
    The socket 10 according to this embodiment is inserted into and fixed to a wall socket provided in, for example, a wall surface, not shown in the drawings. The socket 10 will connect electrically between the side of the socket 10 and the side of the wall socket by inserting a coupling connection 4c of the socket 10 into an inlet port in the wall socket. Furthermore, a plug for one of various types of electrical devices, not shown in the drawings, is ~ 77578.2013042909472322749; 2013-04-29 10 15 20 25 30 attached to the socket 10 in this embodiment. The socket 10 will electrically connect between the side of the socket 10 and the side of the electrical device by inserting a connection of the plug of the electrical device into the connection inlet port 1aa in the socket 10. The socket 10 according to this embodiment has a pair of connection inlet ports 1aa and a pair connection connections 4c. The pair of connection inlet ports 1aa are formed to insert the plug connections from the front surface of the socket 10. The pair of coupling connections 4c are formed so that the rear surface of the socket 10 comes into contact with the wall socket. Consequently, the pair of coupling connections 4c are inserted into the wall socket. Note that the socket 10 according to this embodiment is structured so that a plug defined by CEE7 / 4, CEE7 / 5, etc. according to IECEE (IEC System for Conformity Testing to Standards for Safety of Electrical Equipment) (IEC System for Conformity Testing to Standards for Safety of Electrical Equipment) are linked to it. Similarly, the socket 10 according to this embodiment is structured to be connectable to a socket defined by CEE7 / 4, CEE7 / 5 and so on. of something similar.
    The socket 10 according to this embodiment has a receiver.
    The receiver receives an instruction signal sent from a transmitter (not shown). As instruction signal can be mentioned, for example, treble signal, infrared beam and the like. Furthermore, the socket 10 has a control circuit which controls the release of an electrical connection between the wall socket as a power supply source and the electrical device side and the electrical connection between the wall socket as a power supply source and the side of the electrical device. For example, the receiver in the interior of the socket 10 receives an instruction signal from the transmitter and based on the instruction signal, the control circuit, which is electrically connected to the receiver, switches between start and stop of ~ 77578.2013042909472322749; 2013-04-29 10 15 20 25 30 the power supply from the wall socket in the wall surface to the side of the electrical device. For example, the socket 10 starts and stops the power supply from the socket side of the wall surface to the side of an electrical device such as a lighting device when a person located at a distance from the socket 10 maneuvers the transmitter. Thus, by simply connecting the light source, which does not have a remote control function, to the socket side of the wall surface via the socket 10, the light device can be turned on, off, and so on. using the transmitter. Note that the socket 10 may include, in addition to the receiver, a sensor device such as a human detection sensor so that power supply is started and stopped in accordance with the presence or absence of a human. The socket 10 can also have a function as an electrical leakage prevention device or the like. Furthermore, the socket 10 is not limited to being connected to a wall socket provided in a wall surface. The socket 10 can be formed without the receiver and be used as an electrical installation device embedded in the wall surface side.
    The first housing 1 and the body 4 are provided separably in the socket 10. The first housing 1 and the body 4 are fitted together to form a box-shaped body having an inner cavity. The first cover 1 and the body 4 can be formed using a resin material which has, for example, an electrically insulating property. The socket 10 according to this embodiment is constructed by fitting together the angular tubular first housing 1 with closed end and the angular tubular body 4 with closed end. Note that in the first housing 1, as shown in Fig. 3, a right side view of the first housing 1 shown in Fig. 3B and a left side view, not shown in the drawings, are symmetrical. Further, in the body 4, as shown in Fig. 4, a right side view of the body 4 shown in Fig. 4B and a left side view not shown in the drawings are symmetrical. ~ 77578.2013042909472322749; 2013-04-29 10 15 20 25 30 The first housing 1 has a rectangular outer shape when viewed from the front and includes a recessed section 1c shaped like a cylindrical shape with a closed end. The recessed section 1c has a central section and the central section is located at a first connection end side in a forward-backward direction of the recessed section 1c. The pair of connection insertion ports 1aa into which a pair of pins of the plug, as described above, are inserted separately, are provided on a front surface side of the first housing 1 for penetrating an inner bottom surface (inner front side) of the recessed section 1c.
    Each connection insertion port 1aa is formed in a circular shape so that the columnar pins of the plug are inserted therein when viewed from the front. An inside of the immersed section 1c in the first housing 1 is shaped so that the plug is inserted therein. The plug is not shown in the drawings, but the plug inserted into the recessed section 1c has a columnar outer shape and a plug formed to have side end sections formed by cutting off a portion of a column inside an arcuate column shape can be used. A pair of projecting sections 1ca corresponding to the side end sections of the plug are provided in the recessed section 1c in positions in which the plug is inserted to correspond to each of the pairs of side end sections on the plug side. In the socket 10, the columnar plug can be prevented from rotating relative to the socket 10 by the plurality of (here, four) projecting sections 1ca provided in the recessed section 1c in the first housing 1.
    Further, in the first housing 1, adjacent groups of protruding sections 1ca in the recessed section 1c are provided in opposite pairs, and a slit-shaped pair of opening sections 1cb are provided to extend from an inner wall surface in the lowering surface; 77578.2013042909472322749; 2013-04-29 10 15 20 25 30 10 lowered section 1c to an inner bottom surface (inner front surface) of the lowered section 1c so that a line segment between the opening sections 1cb is orthogonal to a line segment between the opposite projecting sections 1ca (see Fig. 1 and 3). In the socket 10, a contact piece 4ba can function as a retaining element. The connectors 4ba contact the plug elastically when the plug is inserted into the socket 10 to prevent the plug from falling from the recessed section 1c and protrude from each opening section lcb. The pair of connectors 4ba are bent to reduce an inner diameter of the recessed section 1c when projecting from the respective opening sections 1cb and are thereby capable of elastically contacting the plug. The socket 10 according to this embodiment also has a function that the contact pieces 4ba electrically contact the plug side (see Figs. 1, 6 and 10-12).
    The receptacle 10 according to this embodiment includes an elastic member 4b formed of a metal (copper, copper alloy or the like, for example) and has a C-shaped outer shape. The elastic member 4b includes connectors 4ba on respective open end portions of the C-shape. The elastic member 4b can be formed by bending a sheet material.

The fixing screws 8bc also attach a connection bearing spring 4d arranged on a rear surface of the body 4. The connection support spring 4d is configured to contact a round pin-shaped contact connection (not shown) projecting from the wall socket on the wall surface side (see Figs. 1, 8 and 12). The connection bearing spring 4d is formed by bending a sheet material made of metal (copper, copper alloy or the like, for example). Furthermore, the connecting bearing spring 4d is electrically coupled to a contact member 4g which is arranged on the rear side of the body 4 and formed of a metal (copper, copper alloy or the like for example). The contact member 4g has a C-shaped outer shape. The contact member 4g is formed by integrating a base end piece 4gc, side end slots 4gb and fasteners 4ga. The base end piece 4gc is penetrated by an insertion heel 4g1 into which the previously mentioned contact connection is inserted. The side end locations 4gb extend from the respective ends of the base end piece 4gc. The fasteners 4ga extend from the respective side end locations 4gb. The contact member 4g can be formed by bending a plate material made of metal (copper, copper alloy or the like, for example). The contact member 4g has screw heel 4g2 into which the fixing screws 8bc are screwed. The screw heel 4g2 is individually provided to attach pieces 4ga located at the tip end sections of the contact member 4g. In the contact member 4g having a C-shaped outer shape, the fastening piece 4ga is on a tip end section and the connecting support spring 4d is screwed together with the fastening screw 8bc.
    Furthermore, the socket 10 is arranged so that the side end locations 4gb of the contact member 4g are exposed at the surface of cut-away sections 4f1 provided in a side surface of a cylindrical section 4f. The cylindrical section 4f protrudes to the rear side of the body 4 (see Figs. 1, 4, 8-12 and 12). The contact means 4g can also electrically connect a contact connection section (not shown) provided on the wall socket side and the side end locations 4gb on the contact means 4g.
    The socket 10 further includes the pair of coupling terminals 4c which are inserted into the inlet ports on the wall socket provided on the wall side.

The cut-in section 11a forms a closed end-tube-shaped section 11a projecting to the rear surface of the first housing 1. The cut-in section 1i has a through hole 11b formed into a circular shape in an inner surface of the closed end-shaped section 11a, as seen from the front (see Figures 1, 2, 3 and 12). Here, it means undergo- ~ 77578.2013042909472322749; 2013-04-29 10 15 20 25 30 13 end hole lib a first through hole lib of the second cover la. In the socket 10 a circular protective cover 6aa is seen which has a similar outer shape as the cut-in section l in the first cover 1 is seen from the front but is slightly smaller than the cut-in section l1 is inserted in the cut-in section 11 in the first cover 1 from the front surface side of the first housing 1 and held thereby (see Figs. 6, 7 and 9-12). The protective first housing 6aa has been formed as a closed-ended tubular shape to be capable of covering and protecting an indicator lamp 6a arranged in the interior of the socket 10.
    Further, in the first housing 1, the recessed section 1c protrudes incised from the front surface side of the second housing 1a outwardly from the rear side side of the second housing 1a. The plug connections are inserted in the front surface side of the second housing 1a and the rear surface side is opposite the front surface side. As shown in Fig. 2, the first housing 1 includes the shaft section 1b on an outer bottom surface (outer rear surface) of the recessed section 1c, the shaft section 1b projecting from a central section of the outer bottom surface (outer rear surface) to the rear outer side of the second housing 1a. Furthermore, a pair of limiting walls 1d provided on the outer bottom surface (outer back surface) of the recessed section 1c are provided in the first housing 1 for projecting symmetrically around the shaft section 1b arranged as the central section. The limiting wall 1d is arranged in the vicinity of the connection entry port 1a. The pair of limiting walls 1d are arranged in the vicinity of the pair of connection entry ports 1a around the shaft section 1b (see Figs. 2 and 3). Furthermore, the limiting wall 1d has a rectangular shape projecting from the outer bottom surface (outer back surface) of the recessed section 1c.
    In addition, a dividing wall 1k consisting of a partial ring is provided on the rear side of the second housing 1a of the first housing 1 for projecting from the outer bottom surface (outer back surface); 2013-04-29 10 15 20 25 30 14 of the recessed section lc along an outer periphery of the outer bottom surface (outer back surface). The dividing wall 1k is preferably provided to ensure a spatial division in the interior of the socket 10 between a space in which the indicator lamp 6a and so on. is mounted and a space in which the first door 2 is arranged.
    In the first door 2, as shown in Fig. 5, an insertion hole 2b is formed for inserting the shaft section 1b of the first housing 1 provided in a central section of the first door 2. The first door 2 is rotatably supported on the shaft - cut lb. The first door 2 includes the pair of second doors 2a closing the pair of connection entry ports 1a separately and the pair of through-hole sections 2c arranged adjacent to the respective second doors 2a to open the pair of connection entry ports 1a separately.

Furthermore, in the socket 10, the connection support bearing section 4i and the connection terminal 4c are electrically connected to each other via the printed circuit board 5a but not electrically connected to each other directly.
    On the rectangular planar platform printed circuit board 5a, a front surface side of the printed circuit board 5a is in contact with the shaft section 1b of the first housing 1 on a first connection end side in the longitudinal direction (see Figs. 11 and 12). Furthermore, the first door 2 fitted to the shaft section 1b is supported by the pair of door support bearing sections 4a projecting from an inner bottom surface (inner front surface) 40l of the body 4. On the rear side 201 of the first door 2 extends a contact surface 2ab of the first door 2 which a transverse shape from a central section of the first door 2 in which the insertion heel 2b of the first door 2 is provided. In other words, a cross-shaped projecting section 2d is provided on the central section of the rear surface 202 of the first door 2 and the cross-shaped contact surface 2ab is shaped so as to protrude from the rear surface 202 of the first door 2. The cross-shaped contact surface 2ab of the first door 2 is in contact with the first door support bearing section 4a projecting from the inner bottom surface (inner front surface) 401 of the body 4. In the socket 10 according to this embodiment, the connection of the plug presses on the second door 2a of the first door 2 when inserted so that a resulting force exerted on the first door 2 is received on the side of the door bearing section 4a. Note that the door support bearing section 4a consists of a pair of parallel platformed bodies which are integral with the body 4 for projecting from the inner bottom surface (inner front surface) 401 ~ 77578.2013042909472322749; 2013-04-29 10 15 20 25 30 19 of the body 4. The pair of platformed bodies of the door support bearing section 4a are inserted separately into the opening sections 5g of the printed circuit board 5a. Opposite surfaces which sit on the pair of platform bodies constituting the door support bearing section 4a are arranged aligned along one side from each rectangular opening section 5g. In the socket 10, the force exerted on the first door 2 is received as a force exerted in a direction for compression of the first door support section 4a. Thus, in the socket 10 there is no need to support the first door 2 rotatably on the first housing 1 using a stick or the like made of metal, which have greater strength than resin and as a result the socket 10 can be constructed with a comparatively simple configuration.
    In other words, in the socket 10 according to this embodiment, the first door 2 is rotatably supported by the shaft section 1b, which is cast integral with the first housing 1 instead of a metallic pin or the like to rotatably support the first door 2 In the socket 10 according to this embodiment, the number of components in the socket 10 can therefore be reduced in accordance with the omission of the metallic pin or the like, and an assembly process can be simplified.
    Thus, with the socket 10 according to which it has the embodiment, a total manufacturing cost for the socket can be reduced. Furthermore, by providing the first door 2 with the cross-shaped contact surface 2ab, a frictional force generated between the first door 2 and the door support section 4a when the first door 2 rotates can be reduced compared to the case where the entire rear surface 202 of the first door 2 is in contact with the door support bearing section 4a, and at the same time the force exerted on the first door 2 can be spread. This type of first door 2 can be formed comparatively easily by injection molding or ~ 77578.2013042909472322749; 2013-04-29 10 15 20 25 30 20 similar with the use of a resin material that has an electrical insulating property (urea resin or similar, for example). Note that the door support bearing section 4a is not limited to a pair of platform bodies and may take various shapes such as a cylindrical body projecting from the side of the body 4.
    The door bearing section 4a is molded integral with the body 4 to project from the inner bottom surface (inner front surface) 401 of the body 4. Therefore, the door bearing section 4a can be formed comparatively easily with a configuration having a large mechanical strength relative to the compressive force required from the first door 2. As long as sufficient strength can be ensured in the door bearing section 4a in relation to the pressing force received from the first door 2, moreover the door bearing section 4a is not limited to being formed integral with the body 4 and instead the door bearing section 4a and the body can 4 are formed separately.
    In addition, in the socket 10 according to this embodiment, the spring 3, which is formed as a spiral and has a cylindrical outer shape, is provided between the first housing 1 and the first door 2. The spring 3 is fitted externally on the shaft section 1b on the first housing 1. The spring 3 is locked by inserting a first end section of the spring 3 into a cut-out hole 1g provided in the vicinity of the shaft section 1b on the first housing 1 and locking the first end section to a locking piece (not shown) provided in the interior of the cut-out hole 1g (see Figs. 2 and 3). Furthermore, the spring 3 is locked by inserting a second end section of the spring 3 into a through hole 2g provided in the vicinity of the insertion hole 2b in the first door 2 from the front surface side of the first door 2 and locking the second end section to the rear side side of the first door 2. (see Figs. 1, 2 and 5). Thus, the spring 3 biases the first door 2 around the shaft section 1b so ~ 77578.2013042909472322749; 2013-04-29 10 15 20 25 30 21 that the first door 2 closes the connection entry ports laa. Here, the through hole 2g means a second through hole 2g in the first door 2. In the socket 10 according to this embodiment, the spring 3 is fitted externally on the shaft section 1b to be provided between the first housing 1 and the first door 2, and therefore, the interior space of the outlet 10 is used efficiently. Note that the socket 10 can be constructed using a washer spring arranged between the first housing 1 and the printed circuit board 5a to bias the first door 2 around the shaft section 1b instead of the spring 3 being formed as a spiral. In the socket 10, the configuration for biasing the first door around the shaft section 1b so that the first door 2 closes the connection inlet ports 1a is therefore not limited to the spring 3 formed as a spiral.
    In addition, the spring 3 is not limited to being arranged between the first housing 1 and the first door 2.
    The socket 10 includes an engaging support hook section 1h which engages the side of the body 4 towards the first housing 1. The engaging support hook section 1h is provided in two groups of three in a width direction for a lower side (see Figs. 2 and 3) in the first housing The engaging support hook section 1h is formed in a tapered shape so that a tip end section thereof tapers gradually away from a tubular frame section 1a2 and the inner bottom surface 102 of the first housing 1 in the form of an angled tube with a closed end. In the first housing 1, the frame section 1a2 and the engagement latch sections 1h can be cast undivided.
    The socket 10 also includes a pair of side projecting pieces 4h projecting to an outer side of the body 4 from a tubular frame section 4a2 of the angular tubular body 4 with a closed end in a width direction for a lower side (Figs. 1 and 4) of the body 4. A engaging holes (not shown) engaging with ~ 77578.2013042909472322749; 2013-04-29 l0 l5 20 25 30 22 a plurality (here three) of the engaging pawl sections 1h on the first housing 1 penetrate each side projecting piece 4h. The engaging hole is formed to be large enough to engage one of the groups of three engaging pawl sections 1h on the first housing 1. The side projecting piece 4h is attached to the frame section 4a2 of the angular tubular body 4 with the closed end. The side projecting piece 4h on the body 4 is configured to be elastically deformable in relation to the frame section 4a2. In the body 4, the frame section 4a2 and the side projecting pieces 4h can be cast undivided. In other words, the side projecting piece 4h has a C-shaped outer shape and protrudes from the frame section 4a2 so that the engaging hole is formed in a place which is open to the outside.
    In the socket 10, the engaging pawl sections 1h, which project inwards from the side of the frame section 1a2 of the first housing 1, are inserted into the engaging holes of the side projecting pieces 4h projecting from the frame section 4a2 on the body 4.
    The first housing 1 is fixed in position on the side 4 of the body by engaging the engagement latch sections 1h in the first housing 1 with the engagement holes corresponding to the respective engagement latch sections 1h. In other words, the socket 10 is formed by fitting together the first housing 1 and the body 4. Column-shaped protruding sections 1e are provided in the respective upper side (a left side of the paper surface in Fig. 3) corner sections of the four corners of the rectangle which constitutes the first housing 1 when viewed from the rear. The body 4 includes columnar protruding sections 4j projecting from the inner bottom surface (inner front surface) of the body 4 in corner sections corresponding to the protruding sections le of the first housing 1. A screw insertion hole 4el into which a screw section 7fl of a screw 7f is inserted from the rear side of the body 4 penetrates each protruding section 4j (see fig. ~ 77578.2013042909472322749; 2013-04-29 10 15 20 25 30 23 l and 8). Each protruding section 1e of the first housing 1 is provided with a screw hole lel into which the screw section 7fl of the screw 7f projecting from the screw insertion hole 4el is screwed. The recess 10 is formed by bringing the projecting sections 1c on the first housing 1 and the projecting sections 4j on the body 4 into contact with each other so that the projecting sections 1c and the projecting sections 4j can be screwed together with the screws 7f inserted from the rear side. of the body 4. In the socket 10 the first housing 1 and the body 4 are screwed together with the screws 7f. In the socket, the first housing 1 and the body 4 are fixed undivided by inserting the screws 7f into the screw insertion holes 4e1 from the rear side of the body 4 and screwing the screws 7f into the screw insertion holes 11 provided in the protruding sections 1e of the first housing 1.
    When the first housing 1 and the body 4 are fixed, the socket 10 according to it has the box-shaped outer shape as shown in Figs. 6-10. Note that in the socket 10 a left-hand side view of the first housing 1, shown in Fig. 7, and a right-hand side view not shown in the drawings are symmetrical. In addition, in the socket 10, a lower view of the socket 10, shown in Fig. 9, and a plan view not shown in the drawings, are symmetrical.
    The first housing 1 can be formed by casting the second housing 1a in which the connection entry ports 1a are provided, the shaft section 1b projecting from the rear surface of the second housing 1a, and so on. undivided using a resin material (urea resin or the like for example). The first casing 1 can be formed as an integral cast component by injection molding, in which a heated narrow resin material having an electrical insulating property is injected into a mold and then cooled and hardened. ~ 77578.2013042909472322749; 2013-04-29 10 15 20 25 30 24 In addition, in the socket 10 according to this embodiment, the coupling connection 4c is not limited to a columnar pin and can have other shapes such as a flat contact blade. In addition, in the socket 10 according to this embodiment, the inlet ports into which the pins of the plug are individually inserted are not limited to the two round connection inlet ports 1a and may be inlet ports into which contact blades of another shape, such as flat blades, is inserted. In addition, as long as rotation of the first door 2 about the shaft section 1b is not impaired, the socket 10 may include a ground electrode connection input port (not shown) into which a ground electrode connection on the electrical device side is inserted except the connection input ports 1a.
    An assembly process for the socket 10 according to this embodiment will now be described.
    First, the assembly of the first housing 1 side of the socket 10 will be described.
    In the recess 10 according to this embodiment, the second end section of the spring 3 having a cylindrical outer shape and formed into a spiral is inserted into the through hole 2g in the vicinity of the insertion hole 2b in the central section of the first door 2 from the front surface side 201 of the first door 2 and is locked to the rear surface 202 of the first door 2. Thereafter, in the socket 10 on the side of the first housing 1 of the socket 10, the spring 3 and the first door 2 fit externally on the shaft section 1b projecting from the central section of the outer surface 103 of the recessed section 1c which serves as the rear surface side of the first housing 1. In the recess 10, the first end section of the spring 3 is locked to the locking piece in the interior of the cut-out 77578.2013042909472322749; 2013-04-29 10 15 20 25 30 25 the hole lg provided in the vicinity of the shaft section lb of the first housing l. In the first door 2 at this time, the limiting walls 1d of the first housing 1 are inserted into the through-hole section 2c of the first door 2. The first door 2 is biased around the shaft section 1b of the spring 3 so that the through-hole sections 2c provided in the first door 2 and the connection inlet ports 1a provided in the first housing 1 deviate from each other by a predetermined angle (300 for example) around the shaft section 1b. In a state where the connections of the plug are not inserted in the socket 10, the connection inlet ports 1a are thus closed by the other doors 2a and as a result incorrect insertion of foreign material other than the connections through the connection inlet ports 1a can be suppressed.
    In the following, the composition of the body side 4 of the socket 10 will be described.
    In the socket 10 according to this embodiment, the coupling connection 4c is cast integral with the body 4 on the rear side of the body 4 by injection molding. On the body 4 side of the socket 10, the power supply connection 4e is fixed to the coupling connection 4c on the side of the body 4 from the front surface side of the body 4 with the screw 8ca. In addition, on the body 4 side of the receptacle 10, the contact member 4g is arranged on the rear surface 402 of the body 4 in advance via the connecting support spring 4d, the contact member 4g being attached from the front surface side of the body 4 via the elastic member 4b using the fixing screw 8bc. In addition, on the side of the body 4 of the socket 10, the connecting bearing section 4i is attached to the body 4 from the front surface side of the body 4 with the fixing screw 8ia. As a result, in the body 4, the contact piece 4ba of the elastic member 4b pushes the power supply connection ~ 77578.2013042909472322749; 2013-04-29 10 15 20 25 30 26 connecting piece 4e3 and connecting piece 4i2 of the connecting bar bearing section 4i out from the inner front surface side 401 of the body 4.
    With the socket in it, the state is the printed circuit board 5a on which the electronic components have been mounted pre-stacked on the side of the body 4. The printed circuit board 5a is supported in the socket 10 by ribs 4k or the like projecting from the inner front surface side 401 of the body 4. Hair in the printed circuit board 5a the connecting piece 4e3 of the power supply connection 4e is forced into the coupling hole 5e in the printed circuit board 5a. Furthermore, in the printed circuit board 5a, the connecting piece 4i2 of the connection bar bearing section 4i is inserted through the hole 5f in the printed circuit board 5a. Hari, the through hole 5f means a second through hole 5f in the printed circuit board 5a. In the printed circuit board 5a, one of the connectors 4ba of the elastic member 4b is inserted into an opening hole 5h in the printed circuit board 5a. The second contact piece 4ba of the elastic member 4b is arranged on an outer side of the outer shape of the printed circuit board 5a.
    In the socket 10, for example, the connection piece 4e3 and the circuit sample are fixed by soldering or the like so that the connection piece 4e3 inserted in the connection hole 5e on the printed circuit board 5a is electrically connected to the circuit sample on the side of the printed circuit board 5a. Similarly, the connection piece 4i2 and the circuit sample in the socket 10 are fixed by soldering or the like so that the connection piece 4i2 inserted in the through hole 5f of the printed circuit board 5a is electrically connected to the circuit pattern on the printed circuit board side 5a. ~ 77578.2013042909472322749; 2013-04-29 10 15 20 25 30 27 Finally, the connection of the side of the first housing 1 and the side of the body 4 in the socket 10 will be described.
    In the socket 10, the engaging locking hook section 1h of the first housing 1 engages with the engaging holes in the side projections 4h of the body 4. In the socket 10, the first housing 1 and the body 4 are aligned so that the pair of door support bearing sections 4a projecting from the inner front surface 401 of the body 4 support the first door 2 from the opposite surface side which is attached to the first housing 1, thereby preventing the first door 2 from to fall from the shaft section lb. In a state in the socket 10 where the contact piece 4ba of the elastic member 4b projects from the opening section 1cb of the first cover 1, the first cover 1 and the body 4 are screwed together with the screw 7f from the rear side of the body 4.
    In the socket 10 according to this embodiment, formed as described above, when the connections of the plug of the side of the electrical device are not inserted, incorrect insertion of foreign material into the interior of the socket 10 from the outside of the socket 10 via the connection inlet ports 1aa is prevented with the first door 2 formed so that the second doors 2a close the connection inlet ports 1aa.
    When the socket 10 according to this embodiment is connected to the side of the electrical device, the connections on the plug are inserted into the connection inlet ports 1aa to push the other doors 2a which close the connection inlet ports 1aa. When the connections are inserted into the socket 10, the connections come into contact with the inclined surfaces of the respective second doors 2a which slope towards the rear in the insertion direction of the plug connection, a force acting in the direction of rotation of the first door 2 against an elastic force of ~ 77578.2013042909472322749; 2013-04-29 10 15 28 the spring 3. In the socket 10, when the connections come into contact with the second doors 2a, the first door 2 rotates and at a point where the through-hole sections 2c provided in the first door 2 are aligned with the connection in the supply ports 1a provided in the first housing 1, the connections can be inserted into and connected to the connection carrier spring sections 4i1 housed in the interior of the socket 10. Furthermore, when the plug connections of the plug 10 are withdrawn from the connection inlet ports 1a of the socket 10, the first door 2 is caused to rotate around the shaft section 1b by the elastic force from the spring 3 so that the second doors 2a close the connection inlet ports 1a. Thus, with the socket 10 according to this embodiment, incorrect introduction of foreign substances can be suppressed by means of a relatively simple structure. ~ 77578.2013042909472322749; 2013-04-29
