Description

[Technical Field]

[0001] The present disclosure relates to connectors. [Background technology]

[0002] A female terminal described in JP 2019-145208 A (Patent Document 1 listed below) is known. This female terminal includes a terminal body having deformable upper and lower connection pieces extending in an extension direction, and a slide portion movable relative to the terminal body in the extension direction. With a core wire of an electric wire disposed between the upper and lower connection pieces, moving the slide portion causes the upper and lower abutment portions provided on the slide portion to press the upper and lower connection pieces against the core wire, thereby electrically connecting the terminal body and the electric wire. Patent Document 1 listed below also describes a connector equipped with this female terminal, which includes a connector housing that accommodates the female terminal and a rear holder attached to a rear end of the connector housing in the extension direction. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-145208 Summary of the Invention [Problem to be solved by the invention]

[0004] The above connector is manufactured as follows. First, the female terminal is accommodated in the connector housing, and the rear holder is assembled to the rear end of the connector housing. In this state, the rear holder is held in a temporary locking position relative to the connector housing. Next, an electric wire is inserted through the insertion hole of the rear holder, and the core wire of the electric wire is inserted into the female terminal. At this time, the core wire is disposed between the upper and lower connection pieces. Next, the slide portion is moved forward relative to the terminal body, causing the upper and lower abutment portions to press the upper and lower connection pieces against the core wire, thereby connecting the female terminal to the electric wire. Finally, the rear holder is moved forward from the temporary locking position to a full locking position, which prevents the female terminal from slipping out of the connector housing, completing the manufacturing process of the connector.

[0005] Consider manufacturing a similar connector to the above configuration by reducing the diameter of the electric wire without changing the connector housing and rear holder. When the diameter of the electric wire is reduced, it is necessary to reduce the vertical distance between the upper and lower contact portions that press the upper and lower connection pieces that sandwich the core wire of the electric wire. Therefore, the inner diameter of the sliding portion becomes smaller in the vertical direction compared to the above configuration. Therefore, if the size of the sliding portion is simply reduced without changing the configuration of the sliding portion, the core wire may hit the rear end of the sliding portion, making it impossible to insert the core wire into the female terminal. [Means for solving the problem]

[0006] The connector of the present disclosure is a connector that has a first core wire and is connected to a first electric wire extending in a front-to-rear direction, and includes: a first terminal connected to the first core wire; and a connector housing that accommodates the first terminal and through which the first electric wire is inserted. The first terminal includes a first terminal body and a first slide portion that is fitted into the first terminal body from the outside and is capable of sliding in the front-to-rear direction. The first terminal body includes a clamping portion that clamps the first core wire. The first slide portion has a core wire insertion port through which the first core wire is inserted from the rear, a pressing portion that presses the clamping portion against the first core wire inserted from the core wire insertion port, a guide portion that is arranged at the rear end of the first slide portion and inclined inward toward the first slide portion as it extends forward, and a connecting portion that continuously connects the pressing portion and the guide portion in the front-to-rear direction. The connector is a connector that is arranged outward of the first slide portion relative to the pressing portion. [Effects of the Invention]

[0007] According to the present disclosure, it is possible to provide a connector capable of guiding the insertion of a core wire into the interior of a terminal accommodated in a connector housing. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described.

[0010] (1) A connector disclosed herein is a connector connected to a first electric wire having a first core wire and extending in a front-to-rear direction, the connector comprising: a first terminal connected to the first core wire; and a connector housing that accommodates the first terminal and through which the first electric wire is inserted. The first terminal comprises a first terminal body and a first slide portion that is fitted to the first terminal body from the outside and is capable of sliding in the front-to-rear direction. The first terminal body comprises a clamping portion that clamps the first core wire. The first slide portion has a core wire insertion port through which the first core wire is inserted from the rear, a pressing portion that presses the clamping portion against the first core wire inserted from the core wire insertion port, a guide portion that is arranged at a rear end of the first slide portion and inclined inwardly of the first slide portion as it extends forward, and a connecting portion that continuously connects the pressing portion and the guide portion in the front-to-rear direction. The connector is a connector.

[0011] When the diameter of the first core wire is reduced, the first sliding part, which has a pressing part that presses the first core wire against the clamping part, tends to become smaller in the direction perpendicular to the front-rear direction, which may make it difficult to insert the first core wire into the first sliding part.

[0012] According to the above configuration, the guide portion is provided behind the pressing portion via the connecting portion. This guide portion is inclined inwardly toward the first sliding portion as it extends forward. Therefore, the insertion of the first core wire into the first sliding portion is guided. Furthermore, the guide portion is disposed outwardly of the first sliding portion relative to the pressing portion. This makes it easy to enlarge the core wire insertion opening in a direction perpendicular to the front-to-rear direction, making it easier to insert the first core wire into the first sliding portion.

[0013] (2) The above connector preferably has a second core wire and is connected to a second electric wire extending in a front-to-rear direction, and includes a second terminal connected to the second core wire, the diameter of the second core wire being larger than the diameter of the first core wire, the second terminal being accommodated in the connector housing, the second electric wire being inserted into the connector housing, the second terminal including a second terminal body and a second slide portion that is slidable in the front-to-rear direction while fitted into the second terminal body from the outside, the second terminal body including a clamping portion that clamps the second core wire, and the second slide portion including a core wire insertion opening through which the second core wire is inserted from the rear, and a pressing portion that presses the second core wire, inserted from the core wire insertion opening and positioned at the position of the clamping portion in the front-to-rear direction, against the clamping portion.

[0014] With this configuration, even if the diameter of the second core wire is larger than the diameter of the first core wire, a connector can be configured that is connected to both a first electric wire having a first core wire and a second electric wire having a second core wire without changing the connector housing.

[0015] (3) The second terminal body is preferably the first terminal body.

[0016] With this configuration, the first terminal body can be used as the second terminal body, eliminating the need to manufacture a new second terminal body, thereby reducing the manufacturing cost of the connector.

[0017] (4) It is preferable that the first slide portion is arranged outward of the guide portion and has an outer wall portion extending in the front-to-rear direction, the rear end of the guide portion and the rear end of the outer wall portion are in contact with each other, and the connector housing has a locking portion facing the rear end of the outer wall portion in the front-to-rear direction.

[0018] With this configuration, the provision of the outer wall portion increases the engagement margin between the rear end of the first slide portion and the connector housing. Also, since the rear end of the guide portion and the rear end of the outer wall portion are in contact with each other, deformation of the guide portion due to external forces, etc., can be suppressed.

[0019] (5) It is preferable that the first slide portion comprises an intermediate wall portion sandwiched between the outer wall portion and the connecting portion, and a folding portion that continuously connects the outer wall portion and the intermediate wall portion and is folded in a U-shape, and that the intermediate wall portion is folded over the outer wall portion.

[0020] With this configuration, the provision of the intermediate wall portion allows the first sliding portion to be enlarged in a direction perpendicular to the front-rear direction. This makes it easy to configure the first sliding portion to fit the size of the accommodating portion of the connector housing that accommodates the first terminal, even if the diameter of the first core wire is small. This makes it possible to suppress rattling of the first terminal in the accommodating portion.

[0021] (6) It is preferable that the first slide portion has an inclined portion formed continuously on the front side of the pressing portion, the inclined portion inclining outward from the first slide portion as it moves forward, and the inclined portion is positioned further outward from the first slide portion than the pressing portion.

[0022] With this configuration, when the first sliding portion is slid forward relative to the first terminal body, the clamping portion comes into sliding contact with the inclined portion, making it easier to guide the clamping portion inward of the first sliding portion relative to the pressing portion, thereby making it easier for the pressing portion to press the first core wire against the clamping portion.

[0023] (7) The connector housing includes an inner housing that accommodates the first terminal, and a rear holder that is assembled to the rear portion of the inner housing and through which the first electric wire is inserted, and the rear holder is configured to be engaged with the inner housing at either a temporary locking position or a full locking position that is located forward of the temporary locking position, and it is preferable that when the pressing portion presses the first core wire against the clamping portion, the rear holder can be engaged at the full locking position.

[0024] With this configuration, the connector can be made smaller in the front-rear direction while the pressing portion presses the first core wire against the clamping portion.

[0025] [Details of the embodiments of the present disclosure] The present disclosure will be described below with reference to exemplary embodiments. The present disclosure is not limited to these examples, but is defined by the scope of the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0026] <Embodiment> An embodiment of the present disclosure will be described with reference to Figures 1 to 22. In the following description, the direction indicated by arrow Z is defined as upward, the direction indicated by arrow X as forward, and the direction indicated by arrow Y as leftward. Note that, for multiple identical components, only some of the components may be designated by reference numerals, and the reference numerals for the other components may be omitted.

[0027] [connector] As shown in Figures 1 and 2, the connector 10 of this embodiment includes a first terminal 20 connected to an end of the first electric wire 11A, a second terminal 40 connected to an end of the second electric wire 11B, and a connector housing 60 that accommodates the first terminal 20 and the second terminal 40 and through which the first electric wire 11A and the second electric wire 11B are inserted.

[0028] [First Wire] As shown in Figures 16 and 17, the first electric wire 11A is disposed so as to extend in the front-to-rear direction. The first electric wire 11A includes a first core wire 12A and a first insulating coating 13A that covers the outer surface of the first core wire 12A. The first core wire 12A is made of a conductive metal and is a stranded wire made of multiple metal wires twisted together, or a single core wire made of a single metal wire. The first insulating coating 13A is made of an insulating synthetic resin. The first core wire 12A is exposed at the front end of the first electric wire 11A.

[0029] [Second wire] As shown in FIGS. 19 and 20, the second electric wire 11B is disposed extending in the front-rear direction. The second electric wire 11B includes a second core wire 12B and a second insulating coating 13B covering the outer circumferential surface of the second core wire 12B. The second core wire 12B is made of a conductive metal and is a stranded wire formed by twisting together a plurality of metal wires or a single core wire formed by a single metal wire. The second insulating coating 13B is made of an insulating synthetic resin. The second core wire 12B is exposed at the front end of the second electric wire 11B. As shown in FIG. 1, the diameter of the second core wire 12B is larger than the diameter of the first core wire 12A. The outer diameter of the second insulating coating 13B is larger than the outer diameter of the first insulating coating 13A. The outer diameter of the second insulating coating 13B may be the same as the outer diameter of the first insulating coating 13A.

[0030] [1st terminal] The first terminal 20 is made of a conductive metal. As shown in FIG. 1 , the first terminal 20 includes a first terminal body 21 and a first slide portion 22 that is movable in the front-to-rear direction relative to the first terminal body 21. The first terminal body 21 and the first slide portion 22 are formed by performing a press process or the like on a conductive metal plate. The metal that constitutes the first terminal body 21 and the first slide portion 22 can be selected appropriately from any metal as needed, such as copper, copper alloy, aluminum, aluminum alloy, stainless steel, etc. A plating layer may be formed on the surface of the first terminal body 21 and the first slide portion 22. The metal that constitutes the plating layer can be selected appropriately from any metal as needed, such as tin, nickel, silver, etc.

[0031] [First terminal body] As shown in Fig. 9, the front portion of the first terminal body 21 is a connecting tubular portion 23 having a rectangular cylindrical shape extending in the front-rear direction. A lance 23A is formed on the front side of the upper wall of the connecting tubular portion 23 so as to protrude upward in a mountain shape. As shown in Fig. 11, a resilient contact piece 23B is provided inside the connecting tubular portion 23. A plate-shaped mating terminal (not shown) is adapted to be inserted into the connecting tubular portion 23 from the front. The mating terminal inserted into the connecting tubular portion 23 comes into contact with the resilient contact piece 23B.

[0032] 9, a rectangular cylindrical base 24 is provided at the rear of the connecting tube 23. An outwardly protruding locking projection 24A is formed on the side wall of the base 24. A clamping portion 25 is provided at the rear end of the base 24.

[0033] [Holding part] The clamping portion 25 includes an upper connection piece 25A extending rearward from the rear end of the upper wall of the base 24, and a lower connection piece 25B extending rearward from the rear end of the lower wall of the base 24. The upper connection piece 25A and the lower connection piece 25B are elongated in the front-to-rear direction and have approximately the same length in the front-to-rear direction. The upper connection piece 25A and the lower connection piece 25B are formed to be elastically deformable in the up-and-down direction with the rear end of the base 24 as a fulcrum. As shown in FIG. 17 , the lower surface of the upper connection piece 25A and the upper surface of the lower connection piece 25B clamp the first core wire 12A, electrically connecting the first electric wire 11A and the first terminal body 21.

[0034] 9, an upper holding projection 26A that protrudes downward is provided on the underside of the upper connection piece 25A at a position forward of the rear end. A lower holding projection 26B that protrudes upward is provided on the rear end of the upper surface of the lower connection piece 25B. The upper holding projection 26A and the lower holding projection 26B are provided at positions offset from each other in the front-to-rear direction.

[0035] [First slide part] 3, the first sliding portion 22 has a rectangular cylindrical shape extending in the front-rear direction. The first sliding portion 22 includes a front-side tubular portion 22A and a rear-side tubular portion 22B that is connected to the rear side of the front-side tubular portion 22A. The rear-side tubular portion 22B is smaller in the up-down direction than the front-side tubular portion 22A.

[0036] As shown in FIG. 3 , the rear tube portion 22B includes a bottom wall portion 27, a first top wall portion 28 facing the bottom wall portion 27, a first side wall portion 29A connecting the left edge of the bottom wall portion 27 to the left edge of the first top wall portion 28, and a second side wall portion 29B connecting the right edge of the bottom wall portion 27 to the right edge of the first top wall portion 28. The first side wall portion 29A and the second side wall portion 29B are referred to as side wall portions 29 when not particularly distinguished. As shown in FIG. 6 , the first top wall portion 28 includes a portion formed by stacking three metal plates. In detail, the first top wall portion 28 includes an inner wall portion 28A disposed inside the rear tube portion 22B, an outer wall portion 28B disposed outside the rear tube portion 22B, and an intermediate wall portion 28C sandwiched between the inner wall portion 28A and the outer wall portion 28B. The intermediate wall portions 28C are disposed on the front and rear sides of the rear-side tubular portion 22B. As shown in Fig. 7, the intermediate wall portions 28C are formed by tightly bending the metal plate material that constitutes the outer wall portion 28B. In other words, the left end edge of the outer wall portion 28B and the left end edge of the intermediate wall portion 28C are continuously connected by the bent portion 28D. The bent portion 28D is formed by bending the metal plate material 180 degrees, and is U-shaped when viewed from the front-to-rear direction.

[0037] As shown in FIG. 3, the rear side tube portion 22B includes a locking protrusion 30A formed continuously with the outer wall portion 28B, and a locking recess 30B that locks with the locking protrusion 30A. The locking protrusion 30A is formed by bending the metal plate material that constitutes the outer wall portion 28B by 90 degrees. In other words, the left edge of the outer wall portion 28B and the upper edge of the locking protrusion 30A are continuously connected by a bent portion 30C. The bent portion 30C is L-shaped when viewed from the front-rear direction. The locking protrusion 30A is inverted T-shaped when viewed from the left. The locking recess 30B is formed in the first side wall portion 29A and has a shape that can accommodate the locking protrusion 30A. The bent portion 30C is arranged alongside the bent portion 28D in the front-rear direction. More specifically, the bent portion 30C is disposed between the front bent portion 28D and the rear bent portion 28D.

[0038] The shape of the rear tubular portion 22B is maintained by the engagement between the locking projections 30A and the locking recesses 30B. The bent portions 30C are aligned with the bent portions 28D in the front-rear direction, so that the intermediate wall portion 28C and the locking projections 30A can be formed by forming slits in the metal plate material constituting the outer wall portion 28B and bending it. Therefore, the metal plate material can be used without waste when forming the intermediate wall portion 28C.

[0039] [Core insertion port] As shown in Fig. 3, a core wire insertion opening 31 for inserting the first core wire 12A into the first slide portion 22 is formed at the rear end of the rear cylindrical portion 22B of the first slide portion 22. As shown in Fig. 16, the first core wire 12A inserted through the core wire insertion opening 31 Between the upper contact piece 25A and the lower contact piece 25B The plate is arranged to extend in the front-rear direction.

[0040] [Pressing part] As shown in Fig. 6, the rear tubular portion 22B of the first slide portion 22 includes a pressing portion 32. The pressing portion 32 includes an upper pressing portion 32A that protrudes downward from the lower surface of the inner wall portion 28A, and a lower pressing portion 32B that protrudes upward from the upper surface of the bottom wall portion 27. As shown in Fig. 17, the pressing portion 32 presses the clamping portion 25, thereby clamping the first core wire 12A between the clamping portion 25. This electrically connects the first electric wire 11A and the first slide portion 22 (first terminal 20).

[0041] 10 to 12, a temporary-lock receiving portion 33A is formed in the side wall of the front tubular portion 22A of the first slide portion 22, at a position close to the front end. A full-lock receiving portion 33B is formed in the side wall of the front tubular portion 22A of the first slide portion 22, at a position rearward of the temporary-lock receiving portion 33A. The temporary-lock receiving portion 33A and the full-lock receiving portion 33B are capable of elastically locking with the locking projection 24A of the first terminal body 21.

[0042] 10 and 11, when the locking projection 24A of the first terminal body 21 and the temporary-lock receiving portion 33A of the first slide portion 22 are locked together, the first slide portion 22 is held in a spaced position relative to the first terminal body 21. In this state, as shown in Fig. 16, the pressing portion 32 of the first slide portion 22 is disposed rearward of the rear end edge of the clamping portion 25 of the first terminal body 21. In this state, the distance between the upper connecting piece 25A and the lower connecting piece 25B is set larger than the diameter of the first core wire 12A.

[0043] 12, when the locking projection 24A of the first terminal body 21 and the main lock receiving portion 33B of the first slide portion 22 are locked, the first slide portion 22 is locked in the pressing position relative to the first terminal body 21. In this state, as shown in Fig. 17, the upper pressing portion 32A of the first slide portion 22 abuts against the upper surface of the upper connecting piece 25A of the first terminal body 21 from above. Furthermore, the lower pressing portion 32B of the first slide portion 22 abuts against the lower surface of the lower connecting piece 25B of the first terminal body 21 from below.

[0044] When the first slide portion 22 is held in the pressing position against the first terminal body 21, the upper pressing portion 32A presses the upper connection piece 25A from above, causing the upper connection piece 25A to elastically deform downward. Furthermore, the lower pressing portion 32B presses the lower connection piece 25B from below, causing the lower connection piece 25B to elastically deform upward. As a result, the first core wire 12A is arranged in a state where it extends in the front-to-rear direction in the space between the upper connection piece 25A and the lower connection piece 25B, and when the first slide portion 22 is held in the pressing position against the first terminal body 21, the first core wire 12A is sandwiched from above and below by the elastically deformed upper connection piece 25A and lower connection piece 25B.

[0045] When the first slide portion 22 is held in the pressing position relative to the first terminal body 21, the upper holding protrusion 26A of the upper connection piece 25A presses the first core wire 12A from above, and the lower holding protrusion 26B of the lower connection piece 25B presses the first core wire 12A from below. In this way, the first core wire 12A is pressed from above by the upper holding protrusion 26A and also pressed from below by the lower holding protrusion 26B, which is positioned offset from the upper holding protrusion 26A in the front-to-rear direction, and is thereby held in a bent state in the up-down direction. This improves the holding force of the first terminal body 21 on the first core wire 12A.

[0046] [Guide section] As shown in FIG. 6 , the rear cylindrical portion 22B of the first slide portion 22 includes a guide portion 34. In this embodiment, the guide portion 34 is provided at the rear end portion of the inner wall portion 28A. The guide portion 34 is inclined inward (downward in this embodiment) of the first slide portion 22 as it extends forward. The rear end portion of the guide portion 34 contacts the rear end portion of the outer wall portion 28B. The front end portion of the guide portion 34 is connected to the rear end portion of the pressing portion 32 (the upper pressing portion 32A in this embodiment) via a connecting portion 35. The connecting portion 35 is a part of the inner wall portion 28A and continuously connects the guide portion 34 and the upper pressing portion 32A in the front-to-rear direction. The guide portion 34 is disposed outward (upper in this embodiment) of the first slide portion 22 relative to the upper pressing portion 32A. The first core wire 12A comes into sliding contact with the guide portion 34, thereby guiding the first core wire 12A into the interior of the first slide portion 22.

[0047] 11 , a pair of guide portions 36 that protrude inward of the first sliding portion 22 are provided on the side wall portion 29 at a position near the rear end of the rear cylinder portion 22B. The guide portions 36 are inclined so as to be positioned more inward of the first sliding portion 22 as they extend forward. The first core wire 12A comes into sliding contact with the guide portions 36, so that the first core wire 12A is guided into the inside of the first sliding portion 22.

[0048] [Slanted part] As shown in FIG. 6 , the first slide portion 22 has an inclined portion 37 disposed in front of the pressing portion 32 (the upper pressing portion 32A in this embodiment). The inclined portion 37 is disposed at the front end of the inner wall portion 28A. The inclined portion 37 is inclined outward (upward in this embodiment) from the first slide portion 22 as it extends forward. The inclined portion 37 is formed continuously with the upper pressing portion 32A in the front-to-rear direction. The inclined portion 37 is disposed above the upper pressing portion 32A. When the first slide portion 22 moves from the separated position to the pressing position relative to the first terminal body 21, the inclined portion 37 comes into sliding contact with the rear end of the upper connecting piece 25A of the first terminal body 21, guiding the upper connecting piece 25A below the upper pressing portion 32A.

[0049] 3, a jig abutment portion 38 that protrudes upward from the upper wall is provided on the front tubular portion 22A of the first slide portion 22. Although not shown, the first slide portion 22 can be moved forward by bringing a jig into contact with the jig abutment portion 38 from behind and pressing it forward.

[0050] [Second terminal, second terminal body] The second terminal 40 is made of a conductive metal. As shown in Fig. 1, the second terminal 40, like the first terminal 20, includes a second terminal body 41 and a second slide portion 42 that is movable in the front-rear direction relative to the second terminal body 41. In this embodiment, the second terminal body 41 is the first terminal body 21.

[0051] [Second slide part] The second slide portion 42 has substantially the same configuration as the first slide portion 22, and therefore the same members as those in the first slide portion 22 are designated by the same names and detailed descriptions thereof will be omitted. As shown in Fig. 4, the second slide portion 42 includes a front-side tubular portion 42A and a rear-side tubular portion 42B. Similar to the front-side tubular portion 22A of the first slide portion 22, the front-side tubular portion 42A of the second slide portion 42 is provided with a temporary-locking receiving portion 53A, a full-locking receiving portion 53B, and a jig abutment portion 58.

[0052] The rear-side tube portion 42B of the second slide portion 42 includes a bottom wall portion 47, a second top wall portion 48 facing the bottom wall portion 47, a first side wall portion 49A (side wall portion 49) connecting the left edge of the bottom wall portion 47 to the left edge of the second top wall portion 48, and a second side wall portion 49B (side wall portion 49) connecting the right edge of the bottom wall portion 47 to the right edge of the second top wall portion 48. As shown in FIG. 8 , the second top wall portion 48 is formed by stacking two metal plates. In detail, the second top wall portion 48 includes an inner wall portion 48A disposed inside the rear-side tube portion 42B and an outer wall portion 48B disposed outside the rear-side tube portion 42B and overlapping the inner wall portion 48A. In other words, the second top wall portion 48 does not include the intermediate wall portion 28C provided in the first top wall portion 28 of the first slide portion 22.

[0053] 4, the rear cylinder portion 42B of the second slide portion 42 includes a locking protrusion 50A formed continuously with the outer wall portion 48B, and a locking recess 50B that locks with the locking protrusion 50A. The left edge of the outer wall portion 48B and the upper edge of the locking protrusion 50A are continuously connected by a bent portion 50C. The locking protrusion 50A and the locking recess 50B are locked together, thereby maintaining the shape of the rear cylinder portion 42B.

[0054] A core wire insertion opening 51 for inserting the second core wire 12B into the second slide portion 42 is formed at the rear end of the rear cylindrical portion 42B of the second slide portion 42.

[0055] 8, the rear tubular portion 42B of the second slide portion 42 includes a pressing portion 52. The pressing portion 52 includes an upper pressing portion 52A and a lower pressing portion 52B. The second slide portion 42 includes an inclined portion 57 formed continuously in front of the upper pressing portion 52A.

[0056] [Comparison of the size of the first and second slide parts] 1, the diameter of the second core wire 12B is larger than the diameter of the first core wire 12A. Therefore, as shown in Fig. 5, the vertical distance between the upper pressing portion 52A and the lower pressing portion 52B of the second slide portion 42 is larger than the vertical distance between the upper pressing portion 32A and the lower pressing portion 32B of the first slide portion 22. Accordingly, the core wire insertion opening 51 of the second terminal 40 is larger in the vertical direction than the core wire insertion opening 31 of the first terminal 20.

[0057] [Connector housing, inner housing] In this embodiment, as shown in FIG. 2, the connector housing 60 includes an inner housing 61 and a rear holder 62 attached to the rear portion of the inner housing 61. As shown in FIG. 1, the inner housing 61 has a rectangular parallelepiped shape that is short in the vertical direction and long in the horizontal direction. The inner housing 61 is made of an insulating synthetic resin. The inner housing 61 includes a plurality of accommodating sections 63 extending in the front-rear direction and accommodating the first terminals 20 or the second terminals 40. The accommodating sections 63 are aligned at intervals in the horizontal direction and are stacked in two tiers, one above the other. The accommodating sections 63 formed in the upper tier and the accommodating sections 63 formed in the lower tier are laterally offset from each other. The number and relative arrangement of the accommodating sections 63 can be changed as appropriate.

[0058] The front end of the accommodating portion 63 is open forward so that the mating terminal can be inserted therein. The rear end of the accommodating portion 63 is open rearward so that the first terminal 20 or the second terminal 40 can be accommodated therein from the rear.

[0059] 15 and 18, the inner housing 61 has a lance receiving portion 64 that engages with the lance 23A when the first terminal 20 or the second terminal 40 is accommodated in the accommodation portion 63. The engagement between the lance 23A and the lance receiving portion 64 prevents the first terminal 20 or the second terminal 40 from slipping out rearward in the accommodation portion 63.

[0060] A front stopper 65 is formed at the front end of the inner housing 61. When the first terminal 20 or the second terminal 40 is inserted into the accommodating portion 63, the front stopper 65 abuts against the first terminal 20 or the second terminal 40 to prevent the first terminal 20 or the second terminal 40 from slipping out to the front of the inner housing 61.

[0061] The inner housing 61 has a partition wall 66 that separates the accommodating sections 63 formed in the upper tier from the accommodating sections 63 formed in the lower tier. As shown in Fig. 1, the inner housing 61 has a partition wall 67 that separates each accommodating section 63 in the left-right direction. This partition wall 67 electrically insulates the first terminal 20 or the second terminal 40 accommodated in each accommodating section 63 from the first terminal 20 or the second terminal 40 adjacent thereto in the left-right direction.

[0062] Temporary locking portions 68A protruding outward are provided near the rear end portions of both left and right side walls of the inner housing 61. Full locking portions 68B protruding outward are provided in front of the temporary locking portions 68A on both left and right side walls of the inner housing 61.

[0063] [Rear holder] The rear holder 62 is box-shaped and opens forward. The rear holder 62 is made of insulating synthetic resin. As shown in FIG. 2, the rear holder 62 fits into the rear half of the inner housing 61 from the outside. Lock receiving portions 69 are provided near the front ends of both left and right side walls of the rear holder 62. The lock receiving portions 69 are generally gate-shaped.

[0064] The temporary locking portion 68A of the inner housing 61 engages with the lock receiving portion 69 of the rear holder 62, thereby holding the rear holder 62 in a temporary locking position relative to the inner housing 61. The full locking portion 68B of the inner housing 61 engages with the lock receiving portion 69 of the rear holder 62, thereby holding the rear holder 62 in a full locking position relative to the inner housing 61.

[0065] 16 and 19, the rear holder 62 is provided with insertion holes 70 at positions corresponding to the respective accommodating portions 63 of the inner housing 61. That is, the multiple insertion holes 70 are aligned in the left-right direction and are arranged in two vertical rows. The inner diameter of the insertion holes 70 is set to be the same as or slightly larger than the outer diameter of the second insulating coating 13B of the second electric wire 11B. The first electric wire 11A or the second electric wire 11B is adapted to be inserted through the insertion holes 70.

[0066] As shown in FIGS. 21 and 22 , the rear holder 62 has a guide portion 71 on the inner wall of the insertion hole 70. The guide portion 71 is disposed above the front end of the insertion hole 70. The guide portion 71 has a curved surface that is positioned more inward of the insertion hole 70 as it extends forward. The first core wire 12A comes into sliding contact with the guide portion 71, which allows the first core wire 12A to easily enter the inside of the first slide portion 22. The second core wire 12B comes into sliding contact with the guide portion 71, which allows the second core wire 12B to easily enter the inside of the second slide portion 42.

[0067] [Latching part] 17 and 20 , the rear holder 62 is provided with a hood portion 72 that opens forward and into which the inner housing 61 is fitted. The rear holder 62 is provided with a locking portion 73 at the rear end of the hood portion 72. The locking portion 73 faces the rear end of the outer wall portion 28B of the first terminal 20 or the rear end of the outer wall portion 48B of the second terminal 40 in the front-rear direction. The locking portion 73 locks with the rear end of the outer wall portion 28B of the first terminal 20 or the rear end of the outer wall portion 48B of the second terminal 40 in the front-rear direction, thereby preventing the first terminal 20 or the second terminal 40 from slipping out rearward within the accommodating portion 63.

[0068] A partition wall receiving portion 74 is provided near the center in the vertical direction of the rear holder 62. This partition wall receiving portion 74 is open forward, and the vertical dimension of the opening is set to be the same as or slightly larger than the vertical thickness dimension of the partition wall 66 of the inner housing 61.

[0069] 15 and 18, when the rear holder 62 is held in the temporary locking position relative to the inner housing 61, the partition wall receiving portion 74 is located rearward of the rear end edge of the partition wall 66 of the inner housing 61. As shown in Figures 17 and 20, when the rear holder 62 is held in the full locking position relative to the inner housing 61, the partition wall 66 of the inner housing 61 fits into the opening of the partition wall receiving portion 74 of the rear holder 62. This prevents the rear holder 62 from shifting in position relative to the inner housing 61 in the up-down direction.

[0070] [Inserting the second core wire into the second slide section] As shown in FIG. 22 , when the second terminal 40 is accommodated in the accommodation portion 63, the rear end of the second top wall portion 48 of the second slide portion 42 is disposed to face the locking portion 73 in the front-to-rear direction. Furthermore, when the insertion hole 70 of the rear holder 62 disposed behind the accommodation portion 63 that accommodates the second terminal 40 is viewed from behind, the rear end of the second top wall portion 48 is not disposed inside the insertion hole 70, as shown in FIG. 14 . Therefore, when the second core wire 12B is inserted into the second slide portion 42, the front end of the second core wire 12B is unlikely to come into contact with the rear end of the second top wall portion 48. Therefore, the insertion of the second core wire 12B into the second slide portion 42 is unlikely to be obstructed.

[0071] [Inserting the first core wire into the first slide part] 21 , with the first terminal 20 accommodated in the accommodation portion 63, the rear end of the first top wall portion 28 of the first sliding portion 22 is disposed to face the locking portion 73 in the front-to-rear direction. Therefore, when the first core wire 12A is inserted into the first sliding portion 22, the front end of the first core wire 12A is unlikely to come into contact with the rear end of the first top wall portion 28. Therefore, the insertion of the first core wire 12A into the first sliding portion 22 is unlikely to be obstructed.

[0072] When the insertion hole 70 of the rear holder 62 disposed behind the accommodating portion 63 that accommodates the first terminal 20 is viewed from the rear, as shown in Fig. 13, the guide portion 34 is disposed inside the insertion hole 70. This is because the vertical distance between the upper pressing portion 32A and the lower pressing portion 32B of the first slide portion 22 is smaller than the vertical distance between the upper pressing portion 52A and the lower pressing portion 52B of the second slide portion 42 (see Fig. 5). By providing the guide portion 34 on the first slide portion 22, the front end portion of the first core wire 12A comes into sliding contact with the guide portion 34, making it easier for the first core wire 12A to enter the inside of the first slide portion 22.

[0073] [Insertion of the first core wire into the first sliding portion according to the comparative example] Here, consider a comparative example that, unlike the present embodiment, does not include the guide portion 34. As shown in Fig. 23 , the third terminal 120 of the connector 110 according to the comparative example includes a first slide portion 122 that does not include the guide portion 34, but is otherwise configured similarly to the first terminal 20. When the third terminal 120 is accommodated in the accommodating portion 63, the rear end of the first top wall portion 128 (inner wall portion 128A) is disposed to face the insertion hole 70 in the front-to-rear direction. Therefore, the front end of the first core wire 12A may come into contact with the rear end of the first top wall portion 128 (inner wall portion 128A), thereby hindering insertion of the first core wire 12A into the first slide portion 122.

[0074] As described above, in this embodiment, the first slide portion 22 is provided with the guide portion 34, so that the first core wire 12A is less likely to come into contact with the rear end portion of the first ceiling wall portion 28 and is easily inserted into the interior of the first slide portion 22.

[0075] [Method of manufacturing connector 10] An example of a method for manufacturing the connector 10 according to this embodiment will be described below. The first terminal body 21, the first slide portion 22, the second terminal body 41, and the second slide portion 42 are formed using a known method. The first slide portion 22 is attached to the first terminal body 21 from behind. The front edge of the first slide portion 22 abuts against the locking projection 24A of the first terminal body 21 from behind, causing the side wall portion 29 of the first slide portion 22 to expand and deform. When the first slide portion 22 is further pushed forward, the side wall portion 29 of the first slide portion 22 returns to its original shape, and the temporary locking receiving portion 33A of the first slide portion 22 locks with the locking projection 24A of the first terminal body 21. This holds the first slide portion 22 in a spaced position relative to the first terminal body 21. This completes the first terminal 20 (see FIG. 10). The second terminal 40 is similarly obtained.

[0076] The inner housing 61 and the rear holder 62 are formed by injection molding synthetic resin. After the first terminal 20 or the second terminal 40 is inserted into the accommodation portion 63 of the inner housing 61 from the rear, the rear holder 62 is assembled to the rear end portion of the inner housing 61 from the rear. As a result, the lock receiving portion 69 of the rear holder 62 elastically deforms and rides onto the temporary-locking portion 68A of the inner housing 61. When the rear holder 62 is further pushed forward, the lock receiving portion 69 returns to its original deformation, and the lock receiving portion 69 elastically locks onto the temporary-locking portion 68A of the inner housing 61. As a result, the rear holder 62 is held in the temporary-locking position relative to the inner housing 61 (see FIGS. 15 and 18).

[0077] A first core wire 12A having a predetermined length is exposed at the end of the first electric wire 11A. The front end of the first core wire 12A is inserted from the rear into an insertion hole 70 disposed at the rear of the housing portion 63 that houses the first terminal 20. The first core wire 12A is guided into the first sliding portion 22 by the guide portion 71 of the rear holder 62 and the guide portion 34 and leading portion 36 of the first sliding portion 22.

[0078] When the first electric wire 11A is further pushed forward, the first core wire 12A enters the inside of the first terminal body 21 and is arranged at the position of the clamping portion 25 in the front-rear direction. That is, the first core wire 12A passes between the upper connection piece 25A and the lower connection piece 25B (see FIG. 16).

[0079] Next, a jig (not shown) is pressed against the jig abutment portion 38 from behind, and the first slide portion 22 is moved forward relative to the first terminal body 21. At this time, the locking projection 24A of the first terminal body 21 and the temporary locking receiving portion 33A of the first slide portion 22 are disengaged, and the side wall portion 29 of the first slide portion 22 rides up onto the locking projection 24A and is expanded and deformed.

[0080] When the jig abutment portion 38 is further pressed forward with the jig, the side wall portion 29 of the first slide portion 22 is restored to its original shape, and the locking projection 24A of the first terminal body 21 elastically locks with the main lock receiving portion 33B of the first slide portion 22. This holds the first slide portion 22 in the pressed position relative to the first terminal body 21.

[0081] When the first sliding portion 22 moves to the pressing position relative to the first terminal body 21, the upper pressing portion 32A of the first sliding portion 22 presses the upper connection piece 25A of the first terminal body 21 downward. Also, the lower pressing portion 32B of the first sliding portion 22 presses the lower connection piece 25B of the first terminal body 21 upward. As a result, the first core wire 12A is sandwiched between the upper connection piece 25A and the lower connection piece 25B from above and below, and the first electric wire 11A and the first terminal 20 are electrically connected (see FIG. 17 ).

[0082] As with the first terminal 20, the second terminal 40 undergoes the same process as the first terminal 20: the second core wire 12B is inserted into the second slide portion 42, and the second slide portion 42 is moved forward relative to the second terminal body 41 (see FIGS. 18 to 20). As a result, the second electric wire 11B and the second terminal 40 are electrically connected.

[0083] Next, when the rear holder 62 is pressed forward, the lock receiving portion 69 of the rear holder 62 rides up onto the full-locking portion 68B of the inner housing 61 and elastically deforms. When the rear holder 62 is pressed forward further, the full-locking portion 68B and the lock receiving portion 69 are locked together. This holds the rear holder 62 in the full-locking position relative to the inner housing 61 (see FIG. 2). This completes the manufacture of the connector 10.

[0084] [Effects of the embodiment] According to the embodiment, the following actions and effects are achieved. The connector 10 according to the embodiment has a first core wire 12A and is connected to a first electric wire 11A extending in the front-rear direction, and includes a first terminal 20 connected to the first core wire 12A, and a connector housing 60 that accommodates the first terminal 20 and through which the first electric wire 11A is inserted. The first terminal 20 includes a first terminal body 21 and a first sliding portion 22 that is slidable in the front-rear direction when fitted into the first terminal body 21 from the outside. The first terminal body 21 sandwiches the first core wire 12A. The first slide portion 22 has a clamping portion 25 that holds the first core wire 12A, and the first slide portion 22 has a core wire insertion port 31 into which the first core wire 12A is inserted from the rear, a pressing portion 32 that presses the clamping portion 25 against the first core wire 12A inserted from the core wire insertion port 31, a guide portion 34 that is arranged at the rear end of the first slide portion 22 and inclined inward of the first slide portion 22 as it moves forward, and a connecting portion 35 that continuously connects the pressing portion 32 and the guide portion 34 in the front-to-rear direction, and the guide portion 34 is arranged outward of the first slide portion 22 than the pressing portion 32.

[0085] When the diameter of the first core wire 12A is reduced, the first sliding portion 22, which includes the pressing portion 32 that presses the first core wire 12A against the clamping portion 25, tends to be reduced in size in a direction perpendicular to the front-rear direction. Therefore, it may be difficult to insert the first core wire 12A into the first sliding portion 22.

[0086] According to the configuration of the embodiment, a guide portion 34 is provided behind the pressing portion 32 via a connecting portion 35. This guide portion 34 is inclined more inwardly into the first sliding portion 22 as it moves forward. Therefore, the insertion of the first core wire 12A into the inside of the first sliding portion 22 is guided. Furthermore, the guide portion 34 is disposed further outward from the first sliding portion 22 than the pressing portion 32. This makes it easy to enlarge the core wire insertion opening 31 in a direction perpendicular to the front-to-rear direction, making it easier to insert the first core wire 12A into the first sliding portion 22.

[0087] The connector 10 of the embodiment has a second core wire 12B and is connected to a second electric wire 11B extending in the front-rear direction. The connector 10 includes a second terminal 40 connected to the second core wire 12B. The diameter of the second core wire 12B is larger than the diameter of the first core wire 12A. The second terminal 40 is accommodated in a connector housing 60. The second electric wire 11B is inserted into the connector housing 60. The second terminal 40 includes a second terminal body 41 and a second terminal body 42. and a second sliding portion 42 that is slidable in the front-to-rear direction when fitted from the outside into second terminal body 41, and second terminal body 41 has a clamping portion 25 that clamps second core wire 12B, and second sliding portion 42 has a core wire insertion opening 51 into which second core wire 12B is inserted from the rear, and a pressing portion 52 that presses second core wire 12B, inserted from core wire insertion opening 51 and arranged at the position of clamping portion 25 in the front-to-rear direction, against clamping portion 25.

[0088] With this configuration, even if the diameter of the second core wire 12B is larger than the diameter of the first core wire 12A, a connector 10 can be configured that is connected to both the first electric wire 11A having the first core wire 12A and the second electric wire 11B having the second core wire 12B without changing the connector housing 60.

[0089] In the embodiment, the second terminal body 41 is the first terminal body 21 .

[0090] With this configuration, the first terminal body 21 can be used as the second terminal body 41, so there is no need to newly manufacture the second terminal body 41. This allows the manufacturing cost of the connector 10 to be reduced.

[0091] In the embodiment, the first slide portion 22 is arranged further outward from the guide portion 34 than the first slide portion 22 and has an outer wall portion 28B extending in the front-to-rear direction, the rear end portion of the guide portion 34 and the rear end portion of the outer wall portion 28B are in contact with each other, and the connector housing 60 has a locking portion 73 that faces the rear end portion of the outer wall portion 28B in the front-to-rear direction.

[0092] According to this configuration, the provision of outer wall portion 28B increases the engagement allowance between the rear end of first slide portion 22 and connector housing 60. Furthermore, since the rear end of guide portion 34 and the rear end of outer wall portion 28B are in contact with each other, deformation of guide portion 34 due to external force or the like can be suppressed.

[0093] In the embodiment, the first slide portion 22 comprises an intermediate wall portion 28C sandwiched between the outer wall portion 28B and the connecting portion 35, and a folding portion 28D that continuously connects the outer wall portion 28B and the intermediate wall portion 28C and is folded in a U-shape, and the intermediate wall portion 28C is folded over the outer wall portion 28B.

[0094] With this configuration, the provision of the intermediate wall portion 28C allows the first slide portion 22 to be enlarged in a direction perpendicular to the front-rear direction. This makes it easy to configure the first slide portion 22 to fit the size of the accommodating portion 63 of the connector housing 60 that accommodates the first terminal 20, even if the diameter of the first core wire 12A is small. This makes it possible to suppress rattling of the first terminal 20 in the accommodating portion 63.

[0095] In the embodiment, the first slide portion 22 has an inclined portion 37 formed continuously on the front side of the pressing portion 32, and the inclined portion 37 inclines outward from the first slide portion 22 as it moves forward, and is positioned further outward from the first slide portion 22 than the pressing portion 32.

[0096] With this configuration, when the first sliding portion 22 is slid forward relative to the first terminal body 21, the clamping portion 25 comes into sliding contact with the inclined portion 37, which makes it easier to guide the clamping portion 25 inward of the first sliding portion 22 relative to the pressing portion 32. Therefore, the pressing portion 32 can easily press the first core wire 12A against the clamping portion 25.

[0097] In the embodiment, the connector housing 60 comprises an inner housing 61 that accommodates the first terminal 20, and a rear holder 62 that is assembled to the rear portion of the inner housing 61 and through which the first electric wire 11A is inserted, and the rear holder 62 is configured to be engaged with the inner housing 61 at either a temporary locking position or a full locking position that is located forward of the temporary locking position, and when the pressing portion 32 presses the first core wire 12A against the clamping portion 25, the rear holder 62 can be engaged at the full locking position.

[0098] With this configuration, while the pressing portion 32 presses the first core wire 12A against the clamping portion 25, the connector 10 can be made smaller in the front-rear direction.

[0099] <Other embodiments> (1) In the above embodiment, the connector 10 includes a first terminal 20 to which the first electric wire 11A is connected and a second terminal 40 to which the second electric wire 11B is connected. However, this is not limited to this, and the connector may be configured not to include a second terminal to which the second electric wire is connected (see FIG. 17). (2) In the above embodiment, the second terminal body 41 is the first terminal body 21, but this is not limitative, and the second terminal body may be different from the first terminal body. (3) In the above embodiment, the first sliding portion 22 includes the guide portion 36, but this is not limitative, and the first sliding portion does not have to include the guide portion.
