专利说明:

[0001] The invention relates to an electrical terminal to be used for a waterproof connector comprising a water seal, used as an electrical connector between different devices to be mounted, for example, in an automobile. Japanese Patent Application Publication No. 2002-198118 suggests an example of a waterproof connector comprising a water seal and an electrical terminal to be inserted therein. Fig. 18 is a broken cross-sectional view of the watertight connector and electrical terminal both suggested in the above identified publication, and Fig. 19 is a front view of the terminal.
[0002] A terminal 70 is manufactured by working a sheet metal press. As illustrated in FIGS. 18 and 19, the terminal 70 comprises a body 71 in the form of a box, and a cylinder portion 72 on which a wire W is compressed and fixed at one end. The body 71 is open at the front so that a second terminal (not shown) is inserted therein to electrically connect to the terminal 70. The body 71 comprises at a side edge on a bottom surface a pair stabilizers 73a and 73b spaced from each other and extending downwardly. The stabilizers 73a and 73b are formed by folding a sheet, and are in the form of a flat sheet having a thickness twice as large as that of the sheet. The front stabilizer 73a has a leading edge 75a aligning with a leading edge of the body 71, and tapering in a direction along the length of the body 71. The rear stabilizer 73b is located near a center in a direction along the length of the body 71, and has a trailing edge 75b which tapers in a direction along the length of the body 71. A recess 77 is defined between the stabilizers 73a and 73b. As mentioned later, a housing 80 is formed with a tab 95 having an engaging portion 92. The engagement portion 92 is engaged with the recess 77 when the terminal 70 is inserted into the housing 80. When the terminal 70 is inserted into a cavity 81 formed in the housing 80, the stabilizers 73e and 73b are mounted in guide grooves 82 and 85 to thereby introduce the terminal 70 into the cavity 81. The housing 80 made of synthetic resin is formed with a plurality of cavities 81 into which terminal 70 is inserted. Each of the cavities 81 comprises, at lateral edges on an inner lower surface, guide grooves 82 in which the stabilizers 73a and 73b of the terminal 70 can be mounted.
[0003] The cavities 81 are divided by a partition wall 83 in the form of a matrix. The housing 80 includes a front wall 84 facing a front end of the cavities 81. The front wall 84 is formed with an opening 90 through which a male terminal (not shown) can be inserted into the cavity 81 to electrically connect to the terminal 70 which has already been inserted into the cavity 81. The housing 80 comprises at the rear a hole 87 leading to all the cavities 81. A rubber stopper 88 is mounted in the hole 87 at a bottom of the hole 87. The rubber stopper 88 is designed to have a predetermined thickness, and a substantially rectangular section to allow the rubber stopper 88 to fit snugly into the hole 87.
[0004] The rubber plug 88 comprises at a circumferential surface of the outer lips 89, and furthermore a plurality of holes 91 aligning with each of the cavities 81 of the housing 80. Each of the holes 91 comprises at an inner surface internal lips 91a deformable by coming into contact with an outer surface of the wire W so as to come into close contact with the outer surface of the wire W. The rubber plug 88 is fixed in the hole 87 through a cover 93 inserted in the hole 87 for compressing the rubber stopper 88. The cover 93 is made of synthetic resin, and has a cross-section such that the cover 93 can be snugly mounted in the hole 87. The cover 93 is formed with a plurality of windows 94 in a die which each align with each of the cavities 81 of the housing 80 and each of the holes 91 of the rubber plug 88 to allow the terminal 70 to be inserted into the cavity 81 through windows 94 and holes 91.
[0005] Each of the windows 94 includes, at side edges on an inner bottom surface, guide grooves 85 in which the outriggers 73a and 73b of the terminal 70 may be mounted. The guide grooves 82 of the housing 80 and the guide grooves 85 of the hood 93 align with each other in a direction in which the terminal 70 is inserted into the cavity 81. The hood 93 includes a pair of arms 96 extending outwardly from upper and lower ends of the hood 93. Projections 86 on an outer surface of the housing 80 are mounted in recesses 96a formed at inner surfaces of the arms 96, and the hood 93 is thus attached to the housing 80 to thereby prevent the rubber plug 88 from being released from the housing 80. As shown in Fig. 18, the terminal 70 which has been inserted into the cavity 81 in the housing 80 is maintained engaged in the cavity 80, since the engaging portion 92 extending from the tab 95 formed in the cavity 81 is resiliently engaged in the recess 77. The stabilizers 73a and 73b extend in a direction perpendicular to a direction in which the terminal 70 is inserted into the cavity 81 and are mounted in the guide groove 82 formed at an inner surface of the cavity 81 to thereby guide the terminal 70 to be inserted into the cavity 81 .
[0006] As illustrated in FIGS. 18 and 19, the terminal 70 includes the stabilizers 73a and 73b formed by folding a side wall of the terminal 70 inwardly from the outside. The stabilizers 73a and 73b have an engagement function with the tab 95 formed in the cavity 81. When the terminal 70 is inserted into the cavity 81 or removed from the cavity 81, rough surfaces of the stabilizers 73a and 73b may interfere with a inner surface of the hole 91 of the rubber plug 88 to thereby damage the rubber plug 88. Here, "rough surfaces" means surfaces of the stabilizers 73a and 73b at which an electrically conductive sheet is cut or punched into a shape of the terminal 70.
[0007] Due to the aforementioned problems in the conventional terminal, it is an object of the present invention to provide a terminal which can be easily inserted into a housing of a waterproof connector, which is unlikely to damage to a rubber plug when the terminal is inserted into the housing, and further, which is difficult to deform even by an external force acting on it in which the terminal is inserted into or removed from the housing. In one aspect of the present invention, there is provided a terminal to be inserted into a receiving space formed in a housing, the terminal comprising a hollow sheath portion, and a first engagement portion to be engaged with a lug formed at the housing. interior of the receiving space, the first engagement portion extending out of the sheath portion, the first engaging portion comprising a first inclined portion having an inclination angle such that a part of the first inclined portion which is closer to one of the opposite ends of the terminal is further away from an axis of the sleeve portion, and a first stop portion extending from an upper end of the first portion inclined towards the axis of the sheath portion, and abutting at a lower end with a ceiling of the sheath portion, the terminal being constituted by a single sheet, the first part of engagement nt being formed by bending a projecting portion about a direction intersecting the axis of the sheath portion, the projecting portion being a portion of the sheet defining the sheath portion and extending parallel to a direction in which the terminal is inserted in the case. The terminal according to the present invention is adapted to include the first engagement portion comprising the first inclined portion having an inclination angle such that a portion which is closer to one of the opposite ends of the terminal is further away of the axis of the sheath portion. Thus, when the terminal is inserted into the receiving space formed in the housing of the waterproof connector, the first inclined portion acts as a wedge to ensure that the terminal can easily be inserted into the housing, and further that the terminal does not damage a rubber plug when the terminal is inserted into the housing. The first engaging portion comprises the first inclined portion mentioned above, and the first abutment portion extending from the upper end of the first inclined portion toward the axis of the sheath portion, and abutting the level of the lower end with the ceiling of the sheath portion. The first engagement portion is formed by folding the projecting portion about the direction intersecting the axis of the sheath portion, the projecting portion being a portion of the sheet defining the sheath portion, and extending parallel to the direction wherein the terminal is inserted into the housing. Thus, the sheath portion and the first engagement portion are integral with one another to thereby have increased rigidity, and therefore the first engagement portion is quite difficult to deform. even if an external force acts on the terminal inserted into the receiving space in the housing, in a direction in which the terminal is inserted into or out of the housing.
[0008] It is preferable that the terminal further comprises a first reinforcement for preventing the first engagement portion from being displaced and / or deformed due to an external force acting thereon parallel to the direction in which the terminal is inserted into the housing, the first reinforcement being located in order to come into contact with the lower end of the first abutment portion. It is preferable that the terminal further comprises a second reinforcement for preventing the first engagement portion from being displaced and / or deformed due to an external force acting thereon parallel to the direction in which the terminal is inserted into the housing, the second reinforcement enclosing the first abutment portion at the lower end with the first reinforcement.
[0009] It is preferable that the terminal further comprises a second engagement portion which is remote from the first engagement portion in a terminal direction in the length direction of the terminal, the second engagement portion extending to outside of the sheath portion, the second engagement portion comprising a second inclined portion having an inclination angle such that a portion of the second inclined portion disposed closer to one of the opposite ends of the terminal is more near the axis of the sheath portion, and a second stop portion extending from an upper end of the second inclined portion toward the axis of the sheath portion and abutting at a lower end with the ceiling of the sheath portion, the second engagement portion being formed by folding a projecting portion about a direction intersecting the axis of the sheath portion, the projecting portion being a portion of the sheet metal terminating the sheath portion and extending parallel to the direction in which the terminal is inserted into the housing.
[0010] It is preferable that the first reinforcement is formed by folding a first protruding portion about a direction parallel to the axis of the sheath portion, the first protruding portion being a portion of the sheet defining the sheath portion, and extending in a direction intersecting the axis of the sheath portion. It is preferable that the second reinforcement is formed by folding a second projecting portion about a direction parallel to the axis of the sheath portion, the second projecting portion being a portion of the sheet defining the sheath portion, and extending in a direction intersecting the axis of the sheath portion. It is preferable that the first reinforcement is in the form of a flat sheet making plane contact with an outer surface of the sheath portion. It is preferable that the second reinforcement is in the form of a flat sheet making plane contact with an outer surface of the sheath portion. The advantages obtained by the present invention mentioned above will be described below. The terminal according to the present invention can be easily inserted into the housing of the waterproof connector, can prevent the rubber plug from being damaged when the terminal is inserted into the housing, and is difficult to deform even if an external force operates in a direction in which the terminal is inserted into and removed from the housing once the terminals are inserted into the housing.

[0015] Fig. 19 is a front view of the terminal shown in Fig. 18. A terminal 100 according to a preferred embodiment of the present invention will be explained below with reference to Figs. 1 to 17. Terminal 100 is made from a single sheet. More specifically, terminal 100 may be formed by steps of punching an electrically conductive sheet 99 into a predetermined shape, and folding the thus punched sheet 99 (see FIGS. 8-10) into terminal 100 As illustrated in FIGS. 1 to 7, the terminal 100 is inserted into a terminal receiving space 51 formed in an electrically insulating housing 50 from the rear to the front of the housing 50, that is, say in a direction indicated with an arrow X (see Figures 1, 2 and 4 to 6). Terminals 100 are inserted into all terminal receiving spaces 51 in housing 50 to thereby define a watertight connector 200 illustrated in FIG. 14. As shown in FIGS. 1 to 3 and 11 to 13, the housing 50 is formed with a plurality of terminal receiving spaces 51 divided by a partition wall 53. The terminal receiving spaces 51 are symmetrically disposed around the dividing wall 53 in two rows in a row. a direction in the direction of the height H and twelve columns in a direction in the width direction W. A gap 56 is formed between a peripheral wall 54 surrounding the terminal receiving spaces 51, and an outer wall 55 of the housing 50. A housing (not shown) of a second connector to be connected to the waterproof connector 200 is partially mounted in the space 56.
[0016] The number of rows or columns of the terminal receiving spaces 51 and the arrangement thereof is not limited to those mentioned above. A front seal 57 is mounted around the peripheral wall 54 at a proximal end of the peripheral wall 54, and a front support 58 is mounted around the peripheral wall 54 at a distal end of the peripheral wall 54. the peripheral wall 54. The front support 58 is slidable relative to the housing 50 in a lengthwise direction L of the housing 50. The front support 58 comprises at a front wall 58a a plurality of openings 58b. each aligning with each of the terminal receiving spaces 51. A projection 58c protrudes rearwardly from the housing 50 from a rear surface of the front wall 58a. The protrusion 58c enters and exits a groove 59 formed at the front of the partition wall 53, when the front support 58 slides in a direction along the length L of the housing 50. A retainer 60 extending in a widthwise direction W is accommodated in the housing 50. As shown in FIG. 2, the retaining element 60 comes into contact with opposite surfaces of the partition wall 53 in the vicinity of a later mentioned tab 52, and occupies a portion of the terminal receiving space 51. As mentioned later, the retainer 60 is adapted to be inserted into and released from the housing 50 in a Widthwise direction W from one side (e.g. a right side) to the other side (e.g. a left side) of the housing 50. A watertight seal 61 and a cover of seal 62 are mounted in the housing 50 at the rear of the casing 50. The watertight seal 61 is formed with a plurality of through holes 61a each aligning with each of the terminal receiving spaces 51. The seal cap 62 is formed with a plurality of through holes 62e each aligning with each of the through holes 61c and each of the terminal receiving spaces 51. As shown in Figures 4 to 7, the terminal 100 includes a hollow shaft portion 10, a first engagement portion 11 , and a second engagement portion 12. The sheath portion 10 is located at a distal end of the terminal 100 in a direction X in which the terminal 100 is inserted into the housing 50. The sheath portion 10a a rectangular section.
[0017] The first engagement portion 11 is engaged with a tab 52 (see Fig. 2) formed within the terminal receiving space 51. The first engagement portion 11 extends outwardly of the sheath portion 10, and is located near a distal end of the sheath portion 10. The second engagement portion 12 is remote from the first engagement portion 11 in a lengthwise direction X of the terminal 100, and extends outwardly of the sheath portion 10 in a manner similar to the first engagement portion 11. The second engagement portion 12 contacts a portion of a surface The first engagement portion 11 includes a first inclined portion 11a having an inclination angle such that a portion of the first inclined portion 11a which is closer to one end than the inner portion of the terminal receiving space 51. back (a right end in Figure 4) of the bo 100 is further away from an axis 10c of the sheath portion 10. The first engagement portion 11 also includes a first abutment portion 11b extending from an upper end of the first inclined portion 11a to the 10c axis. of the sheath portion 10 and abutting at a lower end with a cap 10a of the sheath portion 10. The first abutment portion 11b is in the form of a flat sheet. The second engagement portion 12 includes a second inclined portion 12e having an inclination angle such that a portion which is closer to the rear end of the terminal 100 is closer to the axis 10c of the portion of The second engagement portion 12 also includes a second abutment portion 12b extending from an upper end of the second inclined portion 12a to the axis 10c of the sheath portion 10, and abutting at the a lower end with the ceiling 10a of the sheath portion 10. The second abutment portion 12b is in the form of a flat sheet. The terminal 100 further comprises a first reinforcement 21 intended to prevent the first engagement portion 11 from being displaced and / or deformed due to an external force acting on it parallel to the direction X. The first reinforcement 21 is located on the ceiling 10a of the sheath portion 10, and comes into contact with a lower end of the first abutment portion 11b. The terminal 100 further comprises a second reinforcement 22 for preventing the first engagement portion 11 from being displaced and / or deformed due to an external force acting on it parallel to the X direction. The second reinforcement 22 is located on the ceiling 10e of the sheath portion 10, and comes into contact with a lower end of the first abutment portion 11b. More specifically, the first reinforcement 21 and the second reinforcement 22 grip the first abutment portion 11b at a lower end of the first abutment portion 11b. The terminal 100 further comprises a third reinforcement 23 intended to prevent the second engagement portion 12 from being displaced and / or deformed because of an external force acting on it parallel to the direction X. The third reinforcement 23 is located on the ceiling 10a of the sheath portion 10, and comes into contact with a lower end of the second abutment portion 12b. More specifically, the first reinforcement 21 and the third reinforcement 23 enclose the second abutment portion 12b at a lower end of the second abutment portion 12b. Each of the first to third reinforcements 21, 22 and 23 is in the form of a flat sheet so as to make plane contact with an outer surface of the ceiling 10a of the sheath portion 10. The terminal 100 further comprises a web securing section 13 remote from the second engaging portion 12. Core wires (not shown) exposed from an electrically insulative outer covering of a cable 14 through which electrical signals are Transmitted are compressed on and fixed in the web attachment section 13, and the cable 14 and the terminal 100 are thus electrically connected to each other. As illustrated in FIGS. 8, 9 and 10, the first engagement portion 11 of the terminal 100 is formed by folding a projection portion 11x about a direction intersecting the axis 10c of the sheath portion 10. Protruding portion 11x is a portion of sheet 99 defining sheath portion 10, and extending parallel to direction X. In a similar manner to first engaging portion 11, as illustrated in FIGS. , 9 and 10, the second engagement portion 12 of the terminal 100 is formed by folding a projection 12x about a direction parallel to the axis 10c of the sheath portion 10. The projection 12x is a part of the sheet 99 defining the sheath portion 10, and extending parallel to the direction X. The first, second and third reinforcements 21, 22 and 23 are formed by folding a first projecting portion 21x, a second projecting portion 22x, and a third protruding part 23x around a di parallel to the X direction, respectively. Each of the first to third projections 21x, 22x and 23x is a part of the sheet 99 defining the sheath portion 10, and extending in a direction intersecting the axis 10c of the sheath portion 10. An assembly process of the waterproof connector 200 is explained below with reference to Figs. 1 to 3 and 12 to 17. First, as shown in Figs. 1 and 2, the terminal 100 is inserted into the housing 50 from the rear to the front of the housing 50 in the condition that the front support 58 is held pulled from the housing 50. More specifically, the terminal 100 is first inserted into the through hole 62a of the gasket cover. 62, and then further inserted in the X direction. Thus, the sheath portion 10 of the terminal 100 passes through the through-holes 62a of the seal cover 62 and the through-holes 61a of the seal. 61, and is housed in the reception area When the terminal 100 is in the terminal receiving space 51, the tab 52 of the housing 50 is inserted into a recess formed between the first and second engagement portions 11 and 12.
[0018] Since the first engagement portion 11 protrudes outwardly from the sheath portion 10 having a rectangular section, as shown in FIGS. 16 and 17, the terminal 100 has a shape of a combination of a rectangle and a projection when viewed from the front. The through holes 62a of the seal cap 62 are designed to have a cross sectional shape similar to and slightly larger than the horizontally viewed shape of the terminal 100. Thus, the terminal 100 can not be inserted into the through hole 62a if the terminal 100 is inserted into the through-hole 62a in a posture such that the terminal 100 is circumferentially deflected about the axis 10c of the sheath portion 10, as the three terminals 100 among the four terminals 100 shown in the figures 16 and 17 except the leftmost terminal. Therefore, it is possible to prevent the terminal 100 from being inserted into the through hole 62a in a defective posture. Once the terminals 100 are inserted into all of the terminal receiving spaces 51 of the housing 50 according to the steps mentioned above, the front support 58 is pushed towards the rear of the housing 50. Since the projection 58c of the front support 58 is inserted in the groove 59 formed at the partition wall 53, the tab 52 is held engaged with the sheath portion 10 of the terminal 100. If any of the terminals 100 is in a defective posture as the terminals 100 shown in Fig. 17 except the leftmost, the tab 52 is held deformed to protrude into the groove 59 by means of the first engagement portion 11, and therefore, the front support 58 does not. may not be fully pushed, and thus, the front support 58 can not be engaged with the housing 50. As a result, it detects the terminal 100 in a defective posture. Once the front support 58 is pushed into a predetermined position, the retainer 60 is inserted into the housing 50 through a right side to a left side of the housing 50, as shown in FIG. as shown in FIG. 3, the retaining element 60 is engaged with the terminals 100 in the housing 50. Thus is completed the waterproof connector 200 illustrated in FIG. 14. If any of the terminals 100 is in a defective posture as the terminals 100 shown in Fig. 17 except the leftmost, the retainer 60 abuts at its distal end with the sheath portion 10 or the second engagement portion 12 , and therefore can not be inserted into a predetermined position in the housing 50. Thus, it is possible to detect that any one of the terminals 100 is inserted into the housing 50 in a defective posture.
[0019] The first engagement portion 11 in terminal 100 according to the present embodiment is adapted to include the first inclined portion 11a having an inclination angle such that a portion of the first inclined portion 11a which is closer to the rear end (the right end in Figure 4) of the terminal 100 is further away from the axis 10c of the sheath portion 10, that is to say the first inclined portion 11a inclined upwards to a the rear end of the terminal 100. Thus, when the terminal 100 is inserted into the terminal receiving space 51 through both the through hole 62a of the seal cover 62 and the through hole 61a of the seal at the water 61, the first inclined portion 11a acts as a wedge, and therefore, the terminal 100 can be inserted smoothly and easily into the housing 50, and furthermore, it is possible to prevent the watertight seal water 61 to be damaged by the terminal 100. Furthermore, the first engagement portion 11 is adapted to include the first inclined portion 11a, and the first abutment portion 11b extending from the upper end of the first inclined portion 11a to the 10c axis of the sheath portion 10, and abutting at a lower end with the ceiling 10a of the sheath portion 10. The first engaging portion 11 is formed by folding the projection 11x about a direction intersecting the axis 10c of the sheath portion 10. Here, the projecting portion 11x is a part of the sheet 99 defining the sheath portion 10, and extending parallel to the direction X. Thus, the sheath portion 10 and the first portion 11 are in one piece with each other so as to have increased rigidity, which prevents deformation of the first engagement portion 11 even if an external force acts in the X direction on the terminal 100 that was inserted into the space of receiving terminal 51 in the housing 50.. In a similar manner to the first engagement portion 11, the second engaging portion 12 is adapted to include the second inclined portion 12a, and the second abutment portion 12b extending from the upper end of the second portion. inclined 12a towards the axis 10c of the sheath portion 10, and abutting at a lower end with the ceiling 10a of the sheath portion 10. The second engaging portion 12 is formed by folding the projecting portion 12x about a direction intersecting the axis 10c of the sheath portion 10. The projecting portion 12x is a portion of the sheet 99 defining the sheath portion 10, and extending parallel to the X direction. 10 and the second engagement portion 12 are integral with each other so as to have increased rigidity, which prevents deformation of the second engagement portion 12 even if an external force acts in the X direction on terminal 1 00 which has been inserted into the terminal receiving space 51 in the housing 50. Furthermore, the first and second engagement portions 11 and 12 prevent the terminal 100 from oscillating up and down (movement in a direction perpendicular to the direction X) in the housing 50.
[0020] In the terminal 100, the first abutment portion 11b of the first engagement portion 11 is clamped at a lower end between the first reinforcement 21 and the second reinforcement 22, and further, the second abutment portion 12b of the second engagement portion 12 is clamped at a lower end between the first reinforcement 21 and the third reinforcement 23. This effectively prevents the first and second engagement portions 11 and 12 from being displaced and deformed due to an external force acting on the terminal 100 in the X direction.
[0021] As illustrated in FIGS. 8 and 9, the first reinforcement 21, the second reinforcement 22 and the third reinforcement 23 may be formed by folding the first projecting part 21x, the second projecting part 22x and the third projecting part 23x, respectively, around a direction parallel to the X direction, the first to third projections 21x, 22x and 23x being portions of the sheet 99 defining the sheath portion 10, and extending in a direction intersecting the X direction. a complexity in the manufacturing process of the terminal 100. In addition, the first to third reinforcements 21, 22 and 23 are in the form of a flat sheet in order to make a plane contact with an outer surface of the ceiling 10a of the part sheath 10 to act as a top reinforcement without increasing the size of the terminal 100. The terminal 100 is made from a single sheet 99, as illustrated in FIGS. .
[0022] The plate 99 includes a first zone 101 extending in the X direction to define a bottom of the sheath portion 10, a second zone 102 extending outwardly from one of the lateral edges of the first zone 101 to define a sidewalls of the sheath portion 10, a third zone 103 extending outwardly of the second zone 102 to define the first engagement portion 11, a fourth zone 104 extending outwardly from the another side edge of the first area 101 to define the other side wall of the sheath portion 10, a fifth area 105 extending outwardly of the fourth area 104 to define the ceiling 10a of the sheath portion 10, a sixth zone 106 extending outwardly of the fifth zone 105 to define the first reinforcement 21, a seventh zone 107 extending outwardly of the fifth zone 105 to define the second reinforcement 22, an eighth zone 108 is étenda to the outside of the second zone 102 to define the second engagement portion 12, and a ninth zone 109 extending outwardly of the fifth zone 105 to define the third reinforcement 23. The sixth and seventh zones 106 and 107 are disposed adjacent to each other via a cutout 110 having a width to allow the first abutment portion 11b to be mounted therein. The third and eighth zones 103 and 108 are spaced from each other in the X direction. The sixth and ninth zones 106 and 109 are disposed adjacent each other through a blank 111 having a width for allowing the second abutment portion 12b to be mounted therein. Terminal 100 can be made by folding sheet 99 in a manner as illustrated in FIGS. 8-10. More specifically, second zone 102 is folded perpendicular to first zone 101 to thereby define one of the sidewalls. of the sheath portion 10. The third zone 103 is then folded around a direction intersecting the axis 10c of the sheath portion 10 to define the first engagement portion 11. The fourth zone 104 is then folded perpendicularly relative to at the first zone 101 to thereby define the other side wall of the sheath portion 10. The fifth zone 105 is then folded perpendicular to the fourth zone 104 to thereby define the ceiling 10a of the sheath portion. The sixth zone 106, the seventh zone 107 and the ninth zone 109 are then folded with respect to the fifth zone 105 so as to make plane contact with the fifth zone 105. The eighth zone 108 is then folded around a cutting direction. the axis 10c of the sheath portion 10 to define the second engagement portion 12. Thus terminates the terminal 100.
[0023] INDUSTRIAL APPLICATION The terminal according to the present invention can be widely used in various industrial fields such as the electronic and electrical devices industry and the automotive industry, as a component of a waterproof connector or any similar device to be used for an electrical connection between the devices.
