[0009] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described. The connector cover of the present disclosure includes: (1) A mounting member comprising a retaining member, a receiving member, and a wiring member arranged between the retaining member and the receiving member, the wiring member having an insulating sheet portion and a plurality of electric wires fixed in parallel to the sheet portion, the retaining member having a hole-punching pin protruding toward the receiving member, the receiving member having a pin receiving portion extending from an inner surface facing the sheet portion to an outer surface on the opposite side, the hole-punching pin having a pin body that penetrates and holds the sheet portion and is inserted into the pin receiving portion, and a locking portion that protrudes from the pin body and faces the outer surface of the receiving member so as to be able to contact the outer surface.

[0010] The wiring member is held between the holding member and the receiving member by the hole-punching pin penetrating and holding the sheet portion. Also, the locking portion of the hole-punching pin faces and contacts the outer surface of the receiving member, thereby restricting the holding member from being displaced in a direction opening from the receiving member. Because the hole-punching pin has both the function of holding the wiring member and the function of restricting the holding member from being removed from the receiving member, the structure of the holding member and therefore the connector cover can be simplified compared to when each function is provided in a separate portion of the holding member.

[0011] (2) In the connector cover described above in (1), it is preferable that the pin receiving portion has an inner peripheral edge on the inner surface of the receiving member that cuts through the seat portion between the hole-punching pin and the inner peripheral edge.

[0012] The pin receiving portion receives the hole punching pin, and the seat portion is scraped between the inner peripheral edge of the pin receiving portion and the hole punching pin, so that the seat portion is punched and at the same time the hole punching pin penetrates the seat portion. Therefore, it is possible to properly realize a form in which the hole punching pin penetrates and holds the seat portion.

[0013] (3) In the connector cover described in (2) above, it is preferable that the locking portion has a sloping surface that narrows in diameter toward the tip side in the direction of insertion into the pin receiving portion, an end face located on the tip side, and a corner portion that connects the sloping surface and the end face at an obtuse angle.

[0014] The above configuration (3) allows the sheet portion to be cut while being sandwiched between the corner of the engagement portion and the inner peripheral edge of the pin receiving portion, thereby improving the accuracy of drilling holes in the sheet portion.

[0015] (4) In the connector cover described in any one of (1) to (3) above, it is preferable that the hole-punching pin has a plurality of split pins that are elastically deformable in the radial direction via split grooves.

[0016] Each split pin is elastically deformed during insertion into the pin receiving portion and can elastically return to its original state when insertion into the pin receiving portion is complete. The elastic return of each split pin positions the locking portion so that it can come into contact with the outer surface of the receiving member. This allows the pin body to be smoothly inserted into the pin receiving portion and ensures a sufficient locking allowance for the locking portion with respect to the receiving member.

[0017] [Details of the embodiment of the present disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0018] <Embodiment 1> The connector cover 10 of the first embodiment is provided on the connector 100 shown in Figs. 2 and 3. The connector 100 is configured to include the connector cover 10, the terminal fittings 40, and the housing 60 that accommodates the terminal fittings 40. The connector cover 10 includes the wiring member 20 connected to the terminal fittings 40, and the holding member 80 and the receiving member 90 that protect the wiring member 20 and are held by the housing 60. In the following description, the front side of the connector 100 that is mated with a mating connector (not shown) is referred to as the front side. The up-down direction is based on the up-down direction in Figs. 1 and 2. In Figs. 1 and 2, the arrows X, Y, and Z represent the front, right, and up, respectively. These directions do not necessarily coincide with the directional reference when the connector 100 is mounted on a vehicle (not shown) or the like.

[0019] (Wiring materials) 5, the wiring member 20 has a sheet portion 21 and a plurality of electric wires 22 fixed to the sheet portion 21. The sheet portion 21 is made of an insulating material, for example, a nonwoven fabric. An example of the electric wires 22 is a covered electric wire in which an outer periphery of a conductor 23, such as a core wire, is covered with an insulating covering 24.

[0020] The multiple electric wires 22 are fixed to one surface of the sheet portion 21 (the lower surface in the case of the first embodiment) in a state lined up in the left-right direction. Each electric wire 22 is fixed to one surface of the sheet portion 21 by, for example, a welding means. As the welding means, a known welding means such as ultrasonic welding, heat and pressure welding, high frequency welding, etc. The wiring member 20 is flexible as a whole, and has a flat rectangular shape in a plan view with a reduced height dimension.

[0021] A front end of each electric wire 22 is disposed so as to protrude forward from the sheet portion 21. In addition, at the front end of each electric wire 22, the covering 24 is stripped to expose the conductor 23 (hereinafter, the conductor exposed at the front end of each electric wire 22 is referred to as the "exposed conductor 23").

[0022] In the case of the first embodiment, as shown in Fig. 3, the wiring member 20 has a first wiring member 20A arranged in a lower stage and a second wiring member 20B arranged in an upper stage inside the connector 100. The number of each electric wire 22 fixed to the sheet portion 21 differs between the first wiring member 20A and the second wiring member 20B. Specifically, the first wiring member 20A includes a portion in the left-right central portion of the sheet portion 21 where the electric wire 22 is not fixed, and the number of each electric wire 22 is accordingly smaller than that of the second wiring member 20B. However, the number of each electric wire 22 may be the same between the first wiring member 20A and the second wiring member 20B, or, conversely, the number of each electric wire 22 may be greater in the first wiring member 20A than in the second wiring member 20B.

[0023] (Terminal fittings) 6, the terminal fitting 40 includes a connection member 41 and a slide member 42 that is attached to the connection member 41 so as to be slidable between a separated position and a connected position. The connection member 41 and the slide member 42 are separate from each other. Both the connection member 41 and the slide member 42 are formed by bending a conductive metal plate or the like.

[0024] The connection member 41 has a cylindrical, for example, rectangular, connection body 43. The connection body 43 receives a mating terminal fitting (not shown) from the front and is electrically connected to the mating terminal fitting. The connection member 41 also has a contact portion (not shown) extending rearward from the connection body 43.

[0025] The slide member 42 has a cylindrical, for example, square cylindrical box portion 45. The contact portion of the connection member 41 is inserted into the box portion 45. The slide member 42 has a pressing portion (not shown) inside the box portion 45. When the slide member 42 is in the separated position, the exposed conductor 23 of the electric wire 22 of the wiring member 20 is inserted into the connection member 41. The exposed conductor 23 does not contact the connection member 41 and is disposed away from the contact portion. In this state, the slide member 42 can be pushed forward and reach the connection position. When the slide member 42 is in the connection position, the pressing portion presses the contact portion, and the contact portion contacts the exposed conductor 23. As a result, the electric wire 22 of the wiring member 20 is electrically and mechanically connected to the terminal fitting 40.

[0026] (housing) 1, the housing 60 is composed of a first member 61, a second member 62, and a third member 63. The first member 61, the second member 62, and the third member 63 are arranged in this order in a stacked state from the bottom up. The first member 61, the second member 62, and the third member 63 are all made of synthetic resin.

[0027] As shown in FIG. 1, the first member 61 is configured as a lower housing. The first member 61 has a rectangular shape in a plan view, and is formed long in the left-right direction. The first member 61 has a plurality of first accommodating chambers 64 arranged in a row in the left-right direction on the upper surface side. Each of the first accommodating chambers 64 extends in the front-rear direction in the first member 61 and opens rearward. The terminal fittings 40 are inserted from the rear into the first accommodating chambers 64 and accommodated therein. As shown in FIG. 1, the first member 61 has a front wall 65 constituting the front portion of the housing 60. The front wall 65 has a plurality of terminal insertion holes 66 that communicate with the front openings of each of the first accommodating chambers 64 and each of the second accommodating chambers 71 described later. The terminal insertion holes 66 are opened in two rows, one above the other, and in a row in the left-right direction. A mating terminal fitting (not shown) is connected to the terminal fitting 40 from the front of the housing 60 through the terminal insertion holes 66.

[0028] As shown in FIG. 7, the first member 61 has a flat first cover portion 67 that closes the upper surface of the front part of each first housing chamber 64. The connection member 41 of the terminal fitting 40 is accommodated in the front part of the first housing chamber 64, and the first cover portion 67 prevents the connection member 41 from slipping out upward. The first member 61 has a first exposed surface 68 that opens the upper surface of the rear part of each first housing chamber 64. The slide member 42 of the terminal fitting 40 is accommodated in the rear part of the first housing chamber 64, and is exposed upward by the first exposed surface 68. When a part of the slide member 42 exposed on the first exposed surface 68 (see the protrusion 47 in FIG. 6) is pressed forward, the slide member 42 is moved from the separated position to the connected position. As shown in FIG. 1, the first member 61 has a pair of first housing lock portions 69 at both left and right ends.

[0029] The second member 62 is configured as an inner housing. As shown in FIG. 1 and FIG. 8, the second member 62 has a rectangular shape in a plan view that is slightly smaller than the first member 61, and is formed long in the left-right direction. The lower surface of the second member 62 covers the upper surface of the first member 61 and closes the first exposed surface 68. The second member 62 has a plurality of second housing chambers 71 arranged in a row in the left-right direction on the upper surface side. Each of the second housing chambers 71 extends in the front-rear direction in the second member 62 and is open to the rear. The terminal fitting 40 is inserted from the rear into the second housing chamber 71 and housed therein. The second member 62 has a flat second cover portion 72 that closes the upper surface of the front part of each of the second housing chambers 71, and has a second exposed surface 73 that opens the upper surface of the rear part of each of the second housing chambers 71. The functions of the second cover portion 72 and the second exposed surface 73 are similar to those of the first cover portion 67 and the first exposed surface 68 described above. The second member 62 has a pair of second housing locking portions 74 at both left and right ends. The second member 62 is held by the first member 61 by each of the second housing locking portions 74 being locked to each of the first housing locking portions 69 from the inside.

[0030] The third member 63 is configured as an upper housing. As shown in FIG. 1 and FIG. 9, the third member 63 has a rectangular shape in a plan view that is slightly larger than the first member 61, and is formed long in the left-right direction. The lower surface of the third member 63 covers the upper surface of the second member 62 and closes the second exposed surface 73. The third member 63 has a plurality of housing grooves 75 (see FIG. 3) continuously provided at the rear end of the lower surface. The housing grooves 75 are arranged in a row in the left-right direction at positions corresponding to the second storage chambers 71. The housing grooves 75 have a U-shaped cross section and open downward. The housing grooves 75 are arranged behind the first member 61 and the second member 62 when the first member 61, the second member 62, and the third member 63 are in a stacked state. The electric wires 22 of the second wiring member 20B are inserted into the housing grooves 75 from below.

[0031] As shown in FIG. 2, the third member 63 has an elastically deformable lock arm 76 at the left and right central portion of the upper surface. The lock arm 76 locks the mating connector and holds the connector 100 and the mating connector in a mated state. The third member 63 has a pair of third housing locking portions 77 at both left and right ends. Each third housing locking portion 77 is locked to each first housing locking portion 69 from the outside, so that the third member 63 is held in a stacked state with respect to the first member 61 and the second member 62. The third member 63 has a pair of locking protrusions 78 at both left and right ends and at a rear end portion behind each third housing locking portion 77. Each locking protrusion 78 has a rectangular column shape extending in the vertical direction and is disposed behind each of the first member 61 and the second member 62 when the first member 61, the second member 62, and the third member 63 are in a stacked state. The locking projections 78 are locked to the holding member 80 and the receiving member 90, so that the third member 63 and therefore the housing 60 are held (coupled) to the holding member 80 and the receiving member 90.

[0032] (Receiving member) The receiving member 90 is configured as a lower cover. The receiving member 90 is made of synthetic resin, has a rectangular shape in a plan view, and is formed long in the left-right direction. As shown in FIG. 7, the receiving member 90 is arranged in line with the first member 61 behind the first member 61. As shown in FIG. 1, the receiving member 90 has a flat receiving body 91. The receiving member 90 has a plurality of cover grooves 92 connected to the front end of the receiving body 91. The cover grooves 92 are arranged in a row in the left-right direction at positions corresponding to the first storage chambers 64. The cover grooves 92 have a U-shaped cross section and open upward. As shown in FIG. 3 and FIG. 7, the electric wires 22 of the first wiring member 20A are inserted into the cover grooves 92 from above. The cover grooves 92 and the housing grooves 75 are misaligned with each other in the width direction.

[0033] As shown in Fig. 7, the receiving member 90 has a pair of first receiving portions 93 at the front end of the receiving body 91, on both left and right ends sandwiching each cover groove portion 92. Each first receiving portion 93 has a rectangular recessed shape in cross section and is open upward. The lower portion of each locking projection 78 is fitted into each first receiving portion 93 from above in a positioned state (see Fig. 9).

[0034] As shown in FIG. 1, the receiving member 90 has a flat facing surface 94 facing the wiring member 20 behind each of the cover grooves 92 and each of the first receiving portions 93 on the upper surface of the receiving body 91. The receiving member 90 has a pair of pin receiving portions 95 at both left and right ends of the receiving body 91 and behind each of the first receiving portions 93. Each pin receiving portion 95 is a hole with a circular cross section, penetrates the receiving body 91 in the up-down direction (thickness direction), and opens on the facing surface 94 and the lower surface of the receiving body 91. The inner peripheral edge of each pin receiving portion 95 opening on the facing surface 94 is edge-shaped and is configured as a scraping edge 96 that can scrape the sheet portion 21 between the hole punching pin 83 described later. In addition, the receiving member 90 has a pair of first cover locking portions 97 connected to both left and right ends of the receiving body 91.

[0035] (Retaining member) The holding member 80 is configured as an upper cover. The holding member 80 is made of synthetic resin, has a rectangular shape in a plan view, and is formed long in the left-right direction. As shown in FIG. 10, the holding member 80 is arranged side by side with the third member 63 behind the third member 63. As shown in FIG. 3, the holding member 80 is arranged facing the receiving member 90 with the first wiring member 20A and the second wiring member 20B sandwiched therebetween. As shown in FIG. 1, the holding member 80 has a flat plate-shaped holding body 81. The holding member 80 has a pair of second receiving portions 82 that protrude forward from both the left and right sides of the holding body 81. Each second receiving portion 82 has a rectangular frame shape. The upper portion of each locking protrusion 78 is fitted into each second receiving portion 82 from below in a positioned state (see FIG. 10).

[0036] The lower surface of the holding body 81 is formed flat. As shown in Fig. 3, the holding member 80 has a pair of hole-making pins 83 protruding from the rear of each second receiving portion 82 on the lower surface of the holding body 81. Each hole-making pin 83 has a pin body 83A and a locking portion 83B that is connected to the lower end (tip) of the pin body 83A and protrudes radially outward.

[0037] The pin body 83A is shaped to extend downward from the lower surface of the holding body 81 with the same diameter, and is inserted into the pin receiving portion 95 in a manner that fits it. As shown in FIG. 12, the locking portion 83B is trapezoidal when viewed from the outside in the radial direction. The locking portion 83B has, on its outer surface, a locking surface 83C that protrudes radially outward from the lower end side of the pin body 83A, an end surface 83D that constitutes the lower end surface (tip surface) of the hole-punching pin 83, and a slope 83E that extends while decreasing in diameter from the outer circumferential edge of the locking surface 83C to the outer circumferential edge of the end surface 83D. The locking surface 83C has an outer diameter larger than the inner diameter of the pin receiving portion 95. The locking surface 83C is connected to the outer circumferential surface of the pin body 83A in a curved shape, and is disposed horizontally in the radial direction, or is disposed inclined upward as it goes radially outward. The end surface 83D is circular when viewed from the bottom, and has an outer diameter equal to the outer diameter of the pin body 83A. The end face 83D is disposed so as to be inclined upward as it goes radially outward. The hole-piercing pin 83 has an edge-like corner 83F between the end face 83D and the inclined face 83E, which connects the end face 83D and the inclined face 83E at an obtuse angle.

[0038] The hole-making pin 83 has a split groove 83G in the radial center. The split groove 83G extends in the front-rear direction and opens at the left-right center of the outer peripheral surface of the pin body 83A and the inclined surface 83E. The split groove 83G extends in the vertical direction and opens at the left-right center of the locking surface 83C and the end surface 83D. The split groove 83G is formed so that the left-right width gradually narrows from the lower end opening at the end surface 83D to the upper-lower middle part of the pin body 83A. The hole-making pin 83 has a pair of split pins 83H on both the left and right sides of the split groove 83G. The inclined surface 83E, the locking surface 83C, and the end surface 83D are formed at the lower end (tip) of each split pin 83H. Each split pin 83H is elastically deformable in the radial direction (left-right direction in the case of the first embodiment) that narrows the groove width of the split groove 83G.

[0039] 10, the holding member 80 has a pair of second cover locking portions 85 connected to both left and right ends of the holding body 81. Each second cover locking portion 85 is engaged with each first cover locking portion 97, whereby the holding member 80 is held in a connected state to the receiving member 90.

[0040] (Function of connector cover) The following describes an example of a procedure for assembling the connector 100. The assembly of the connector 100 can be performed automatically, for example, by using an automated machine.

[0041] First, each terminal fitting 40 is accommodated in each first accommodation chamber 64 of the first member 61. At this time, the slide member 42 is arranged at a position separated from the connection member 41. Then, the receiving member 90 is arranged behind the first member 61, and each electric wire 22 of the first wiring member 20A is inserted into each terminal fitting 40 from the rear. Each electric wire 22 is positioned in each cover groove portion 92 of the first member 61. The exposed conductor 23 of each electric wire 22 is arranged inside the terminal fitting 40 from the slide member 42 to the connection member 41. Since each electric wire 22 is fixed to the sheet portion 21 common to each electric wire 22, by moving the sheet portion 21 forward, each electric wire 22 can be inserted into each terminal fitting 40 at the same time. From this state, the slide member 42 of each terminal fitting 40 is moved to the connection position via the first exposed surface 68 (see FIG. 7). As a result, each terminal fitting 40 is connected to each electric wire 22 of the first wiring member 20A. In the case of the first embodiment, each electric wire 22 is fixed to the lower surface of the sheet portion 21.

[0042] Next, the second member 62 is attached to and engaged with the first member 61 from above the first member 61. The first exposed surface 68 is covered by the second member 62. As described above, each terminal fitting 40 is accommodated in each second accommodating chamber 71 of the second member 62, and further each electric wire 22 of the second wiring member 20B is inserted into each terminal fitting 40. Then, the slide member 42 of each terminal fitting 40 is moved to the connection position via the second exposed surface 73 (see FIG. 8).

[0043] Next, the third member 63 is attached to and engaged with the first member 61 from above the second member 62. The second exposed surface 73 is covered by the third member 63 (see FIG. 9). This completes the assembly of the housing 60. The sheet portions 21 of the first wiring member 20A and the second wiring member 20B are disposed at the rear of the housing 60 and supportable on the opposing surface 94 of the first member 61.

[0044] Next, the holding member 80 is attached to the receiving member 90 from above the receiving member 90 and locked (see FIG. 10). In the process of attaching the receiving member 90, the end face 83D of the hole-punching pin 83 comes into contact with the seat portion 21, and each divided pin 83H is deformed in a direction narrowing the split groove 83G. Furthermore, as the attachment of the receiving member 90 progresses, the inclined surface 83E of the hole-punching pin 83 slides on the seat portion 21, and the seat portion 21 is pressed against the opposing surface 94 of the receiving member 90. The seat portion 21 is firmly sandwiched between the inclined surface 83E of the hole-punching pin 83 and the chamfered edge 96 of the pin receiving portion 95. As the holding member 80 further descends, the seat portion 21 is chamfered between the corner portion 83F of the hole-punching pin 83 and the chamfered edge 96 of the pin receiving portion 95, and at the same time, the hole-punching pin 83 penetrates the seat portion 21. In the case of the first embodiment, the hole-making pin 83 simultaneously penetrates the sheet portions 21 of the first wiring member 20A and the second wiring member 20B. As a result, the sheet portions 21 are held in line in the vertical direction by the hole-making pins 83. As shown in FIG. 4, the diameter of the hole formed in the sheet portion 21 is equal to the diameter of the hole-making pin 83 penetrating the hole. For convenience, FIG. 4 omits the second wiring member 20B and illustrates only the state in which the hole-making pin 83 penetrates the first wiring member 20A.

[0045] With the hole-punching pin 83 penetrating the seat portion 21 and inserted into the pin receiving portion 95, each split pin 83H elastically returns, and the locking portion 83B falls below the receiving member 90. As shown in Fig. 11, the locking surface 83C of the locking portion 83B is disposed opposite and contactable with the lower surface (outer surface) of the receiving body 91 of the receiving member 90. By locking the locking portions 83B of each hole-punching pin 83 to the receiving member 90 in this manner, the holding member 80 and the receiving member 90 are firmly held (connected) in a state in which they are restricted from displacing in the direction of opening with each other while sandwiching the seat portions 21.

[0046] As described above, the exposed conductor 23 of the electric wire 22 is pressed against the pressing portion inside the connection member 41 and held against the terminal fitting 40. The holding force with which the terminal fitting 40 holds the exposed conductor 23 tends to be weaker than when the exposed conductor 23 is crimped by the barrel of a general terminal. In this respect, in the case of the first embodiment, for example, even if a tensile force acts backward on the seat portion 21 from the housing 60, the hole-punching pins 83 penetrate and hold the seat portion 21, so that the tensile force can be resisted. For this reason, it is possible to prevent the seat portion 21 from retreating in response to the tensile force, and the position of the seat portion 21 relative to the terminal fitting 40 can be maintained constant. As a result, the state in which each electric wire 22 of the wiring member 20 is connected to each terminal fitting 40 can be maintained.

[0047] As described above, according to the first embodiment, the hole-punching pins 83 of the holding member 80 penetrate and hold the sheet portion 21, so that when an external force such as a tensile force acts on the sheet portion 21, it is possible to prevent the external force from being transmitted to the connection portion between the exposed conductors 23 of each wiring member 20 and the terminal fittings 40. As a result, even in the connector 100 including the wiring member 20 having the sheet portion 21, the connection reliability between the electric wires 22 and the terminal fittings 40 can be ensured.

[0048] Furthermore, the pin receiving portion 95 receives the hole-punching pin 83, and the seat portion 21 is scraped between the scraping edge 96 of the pin receiving portion 95 and the hole-punching pin 83, so that the seat portion 21 is punched and at the same time the hole-punching pin 83 can penetrate the seat portion 21. Therefore, it is possible to properly realize a form in which the hole-punching pin 83 penetrates and holds the seat portion 21.

[0049] In the case of the first embodiment, the first member 61, the second member 62, and the third member 63 are sequentially attached from below while sandwiching the first wiring member 20A and the second wiring member 20B therebetween, and the receiving member 90 and the holding member 80 are also sequentially attached from below, thereby assembling the connector 100. Therefore, the assembly work of the connector 100 can be efficiently performed using an automated machine or the like.

[0050] Furthermore, in the case of the first embodiment, the locking portion 83B of the hole-punching pin 83 faces and contacts the underside of the receiving member 90, thereby restricting the holding member 80 from being displaced in the direction opening from the receiving member 90. Since the hole-punching pin 83 has both the function of holding the wiring member 20 and the function of restricting the holding member 80 from being removed from the receiving member 90, the structure of the holding member 80 and therefore the connector cover 10 can be simplified compared to a case in which each function is provided in a separate portion of the holding member 80.

[0051] Furthermore, since the sheet portion 21 can be chamfered while being sandwiched between the corner portion 83F of the engaging portion 83B and the chamfering edge 96 of the pin receiving portion 95, the accuracy with which the sheet portion 21 is drilled can be improved.

[0052] Furthermore, during the process of inserting the hole-punching pin 83 into the pin receiving portion 95, each split pin 83H elastically deforms in a direction narrowing the split groove 83G, and each split pin 83H can elastically return to its original shape when the insertion of the hole-punching pin 83 into the pin receiving portion 95 is completed. By each split pin 83H returning to its original shape, the locking portion 83B is positioned facing and contactable with the lower surface of the receiving member 90. Therefore, the pin body 83A can be smoothly inserted into the pin receiving portion 95, and a sufficient locking allowance of the locking portion 83B with respect to the receiving member 90 can be ensured.

[0053] [Another embodiment of the present disclosure] The above-described first embodiment disclosed herein should be considered as illustrative in all respects and not restrictive. In the case of the above-mentioned embodiment 1, both the holding member and the receiving member are held (connected) separately from the housing at the rear of the housing. In contrast, according to another embodiment, at least one of the holding member and the receiving member may be held integrally with the housing at the rear of the housing. In the above-mentioned embodiment 1, the wiring member is composed of the first wiring member and the second wiring member. In contrast, according to other embodiments, the wiring member may be composed of only one of the first wiring member and the second wiring member, or may include another wiring member in addition to the first wiring member and the second wiring member. In the case of the above-mentioned embodiment 1, the terminal fitting is configured to be connected to the electric wire by sliding the slide member to the connecting position relative to the connecting member. In contrast, according to another embodiment, the terminal fitting may be a general terminal that is crimped to the electric wire by a barrel. In the case of the above-mentioned embodiment 1, the hole-punching pin has a pair of split pins that are elastically deformable via a split groove. In contrast, according to other embodiments, the hole-punching pin may have three or more split pins that are elastically deformable via a split groove. [Explanation of symbols]
