Description

Technical Field

[0001] This disclosure relates to connectors and methods of manufacturing connectors. Background Technology

[0002] Conventionally, it is known to have wires with terminals on the core wires exposed at the end of the wire. As such a terminal, for example, as disclosed in Japanese Patent Application Publication No. 2005-50736 (Patent Document 1), there is a terminal having a crimping portion that is crimped to the core wire at the end of the wire from the outside.

[0003] To crimp the aforementioned terminal to the wire, the following method is employed: First, a terminal of a predetermined shape is formed by stamping a sheet metal. Next, the terminal is placed in the mounting portion of the lower die, which is located on the lower side of a pair of dies that can move relative to each other in the vertical direction. Then, the core wire at the end of the wire is placed overlappingly on the crimping portion of the terminal. Next, one or both of the dies are moved closer together in a direction that brings them closer together, and the crimping portion is clamped between the crimping portion of the upper die and the mounting portion of the lower die, thereby crimping the crimping portion to the core wire of the wire. Through this process, the terminal is crimped to the end of the wire.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2005-50736 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] In the case where the connecting core wire is clamped by a sliding structure instead of the aforementioned crimping part, the terminal may consist of two parts: a terminal body and a sliding part that slides relative to the terminal body. When such a terminal is housed inside the housing and the terminal body is held in a state where it does not move in the sliding direction, the sliding part is pressed to make it slide, and the housing and terminal body may deform due to the force applied to the sliding part.

[0009] This disclosure is based on the above-described situation and aims to suppress deformation of the housing and terminal body and to use a sliding structure to clamp the connecting core wire.

[0010] Solution for solving the problem

[0011] The connector disclosed herein includes: a terminal for connecting to a core wire located at the end of an electrical wire having a core wire; and a housing having a receiving portion for receiving the terminal, the terminal including: a terminal body having a clamping portion; and a sliding portion that, by pressing the sliding portion from the rear, slides relative to the terminal body, thereby forming a state in which the core wire is clamped by the clamping portion, the housing having an opening that exposes a portion of the front end of the terminal body forward.

[0012] Invention Effects

[0013] According to this disclosure, deformation of the housing and terminal body can be suppressed, and the connecting core wire can be clamped by a sliding structure. Attached Figure Description

[0053] [Details of the embodiments of this disclosure]

[0054] The following describes embodiments of this disclosure. This disclosure is not limited to these examples, but is intended to include all modifications within the meaning and scope of the claims, as shown by the claims.

[0055] <Implementation Method 1>

[0056] While referring to Figures 1 to 13 The following describes Embodiment 1 of this disclosure. In the following description, Figures 1 to 13 In the diagram, the X direction is used as the left, the Y direction as the front, and the Z direction as the top. Furthermore, when referring to multiple identical components, sometimes only some components are labeled with reference numerals, omitting the reference numerals for the others.

[0057] [Connector]

[0058] In this embodiment, the connector 10 houses the terminal 12 that connects to the end of the wire 11. For example... Figures 1 to 3 As shown, the connector 10 includes: a housing 30 having a plurality of storage portions 29 for storing terminals 12; a rear retainer 31 assembled to the rear end of the housing 30; and a cover 48 covering the housing 30 and the rear retainer 31.

[0059] [electric wire]

[0060] like Figure 1 As shown, the wire 11 is arranged extending in the front-to-back direction. The wire 11 is constructed by surrounding the outer peripheral surface of the core wire 13 with an insulating cover 1, which is made of an insulating synthetic resin. The core wire 13 is made of a conductive metal and can be either a stranded wire composed of multiple metal wires twisted together or a single metal wire. The end portion of the insulating cover 14 is stripped to expose the core wire 13.

[0061] [Terminal]

[0062] Terminal 12 is made of metal, such as Figure 4 and Figure 5 As shown, it includes a terminal body 15 and a sliding portion 16 that can slide relative to the terminal body 15.

[0063] [Terminal Body]

[0064] like Figure 4 As shown, the front portion of the terminal body 15 forms a square-shaped connecting tube 17 extending in the front-rear direction. A plate-shaped counterpart terminal (not shown) can be inserted into the connecting tube 17 from the front.

[0065] like Figure 6 As shown, a contact piece 19 extending forward from the rear of the connecting cylinder 17 is disposed inside the connecting cylinder 17. The opposing terminal inserted into the connecting cylinder 17 contacts the contact piece 19. The wall portion of the connecting cylinder 17 that has the contact piece 19 is designated as the first wall portion 17A. The wall portion opposite to the first wall portion 17A is designated as the second wall portion 17B. Figure 7 As shown, the pair of wall portions connecting the two edges of the first wall portion 17A and the two edges of the second wall portion 17B are the third wall portion 17C and the fourth wall portion 17D. Figure 5 As shown, a spear-shaped portion 21 is formed in front of the third wall portion 17C, protruding upward in a mountain-shaped manner.

[0066] like Figure 5 As shown, a square-tube-shaped base 20 is provided behind the connecting cylindrical portion 17. (As shown...) Figure 8 As shown, a clamping portion 18 for clamping the core wire 13 is provided at the rear end of the base 20. Of the clamping portions 18, the clamping portion extending rearward from the rear end of the upper wall of the base 20 is formed as an upper clamping portion 18A, and the clamping portion extending rearward from the rear end of the lower wall of the base 20 is formed as a lower clamping portion 18B. The upper clamping portion 18A and the lower clamping portion 18B are elongated in the front-rear direction, and their lengths in the front-rear direction are equal. The upper clamping portion 18A and the lower clamping portion 18B are configured to elastically deform in the up-and-down direction with the rear end of the base 20 as a fulcrum.

[0067] like Figure 8 As shown, an upper retaining protrusion 23A protruding downwards is provided on the lower surface of the upper clamping portion 18A, at a position forward of the rear end. A lower retaining protrusion 23B protruding upwards is provided at the rear end of the upper surface of the lower clamping portion 18B. The upper retaining protrusion 23A and the lower retaining protrusion 23B are positioned offset in the front-rear direction.

[0068] like Figure 10 As shown, the lower surface of the upper clamping part 18A and the upper surface of the lower clamping part 18B can clamp the core wire 13, electrically connecting the wire 11 and the terminal body 15.

[0069] like Figure 4 As shown, a locking protrusion 28 protruding outward is formed on the side wall of the terminal body 15.

[0070] [Sliding part]

[0071] The cross-section of the inner shape of the sliding part 16 is formed to be the same as or slightly larger than the cross-section of the outer shape of the region in the terminal body 15 where the upper clamping part 18A and the lower clamping part 18B are provided. As a result, the sliding part 16 can be externally fitted into the region in the terminal body 15 where the upper clamping part 18A and the lower clamping part 18B are provided.

[0072] like Figure 8 As shown, a pressure part 25 is provided in the sliding part 16. In the pressure part 25, an upper pressure part 25A protruding downward is disposed on the lower surface of the upper wall of the sliding part 16, and a lower pressure part 25B protruding upward is disposed on the upper surface of the lower wall of the sliding part 16.

[0073] like Figure 4 and Figure 5As shown, a temporary locking portion 26 is opened on the side wall of the sliding portion 16, near the front end in the front-rear direction. Additionally, a permanent locking portion 27 is opened on the side wall of the sliding portion 16, further rear of the temporary locking portion 26. The temporary locking portion 26 and the permanent locking portion 27 can be elastically locked with the locking protrusion 28 provided on the side wall of the terminal body 15.

[0074] The state in which the locking protrusion 28 of the terminal body 15 and the sliding portion 16 are locked by the temporary locking portion 26 changes to a state in which the sliding portion 16 is held in a temporary locked position (an example of the first position) relative to the terminal body 15. In this state, as Figure 8 As shown, the upper pressure portion 25A and the lower pressure portion 25B of the sliding portion 16 are positioned rearward of the rear end edges of the upper clamping portion 18A and the lower clamping portion 18B of the terminal body 15. Furthermore, in this state, the distance between the upper clamping portion 18A and the lower clamping portion 18B is set to be larger than the diameter of the core wire 13.

[0075] The state in which the locking protrusion 28 of the terminal body 15 and the sliding portion 16 are locked by the formal locking portion 27 changes to the state in which the sliding portion 16 is locked relative to the terminal body 15 in the formal locking position (an example of the second position). In this state, as Figure 10 As shown, the upper pressure portion 25A of the sliding portion 16 abuts against the upper surface of the upper clamping portion 18A of the terminal body 15 from above. In addition, the lower pressure portion 25B of the sliding portion 16 abuts against the lower surface of the lower clamping portion 18B of the terminal body 15 from below.

[0076] With the sliding portion 16 in the fully locked position relative to the terminal body 15, the upper clamping portion 18A is pressed down from above by the upper pressure portion 25A, causing the upper clamping portion 18A to elastically deform downwards. Similarly, the lower clamping portion 18B is pressed down from below by the lower pressure portion 25B, causing the lower clamping portion 18B to elastically deform upwards. Thus, the core wire 13 is positioned in the space between the upper clamping portion 18A and the lower clamping portion 18B, extending in the front-rear direction. With the sliding portion 16 in the fully locked position relative to the terminal body 15, the core wire 13 is clamped from the vertical direction by the elastically deformed upper clamping portion 18A and lower clamping portion 18B.

[0077] With the sliding part 16 held in the locked position relative to the terminal body 15, the upper retaining protrusion 23A of the upper clamping part 18A presses the core wire 13 from above, and the lower retaining protrusion 23B of the lower clamping part 18B presses the core wire 13 from below. Thus, the core wire 13 is pressed from above by the upper retaining protrusion 23A and from below by the lower retaining protrusion 23B, which is positioned offset from the upper retaining protrusion 23A in the front-back direction, thereby maintaining it in a bent state in the vertical direction.

[0078] like Figure 4 and Figure 5 As shown, a pressing part 46 protruding upward from the upper wall is provided at the front end of the sliding part 16. Figure 9 As shown, the pressing jig 45 abuts against the pressed part 46 from the rear, and the sliding part 16 is pressed forward by the pressing jig 45, so that the sliding part 16 can move forward.

[0079] like Figure 4 and Figure 5 As shown, a pair of wire guide portions 47 protruding inwards from the sliding portion 16 are provided on the left and right side walls near the rear end of the sliding portion 16. The wire guide portions 47 are narrow in width as they move from the rear to the front. The wire 13 is guided into the sliding portion 16 by sliding against the inner surface of the wire guide portion 47.

[0080] [case]

[0081] like Figure 11 As shown, the housing 30 is formed in a flat, rectangular shape that is short in the vertical direction and extends in the horizontal direction. The housing 30 is formed by injection molding of insulating synthetic resin. In the housing 30, a plurality of storage portions 29 extending in the front-back direction of the storage terminals 12 are arranged at intervals in the horizontal direction and are stacked in two layers. The storage portions 29 formed in the upper layer and the storage portions 29 formed in the lower layer are arranged in a staggered position. Furthermore, the number of storage portions 29 is arbitrary, and the number of layers in the case of vertical stacking is also arbitrary.

[0082] The front end of the storage section 29 is open at the front, allowing the other terminal to be inserted. The rear end of the storage section 29 is open at the rear, allowing the terminal 12 to be stored from the rear.

[0083] like Figure 8 As shown, a locking wall 33 is provided in the housing 30 such that it corresponds to the position of the spear-shaped portion 21 of the terminal 12 when the terminal 12 is housed in the housing portion 29. The spear-shaped portion 21 is locked by the locking wall 33 to prevent the terminal 12 from falling off to the rear.

[0084] like Figure 6 As shown, a front stop 40 is formed at the front end of the housing 30 such that it covers the first wall portion 17A of the terminal 12 from the front. The front stop 40 abuts against the terminal 12 in such a way that it prevents the terminal 12 from falling off towards the front of the housing 30 when the terminal 12 is inserted into the housing portion 29.

[0085] like Figure 6 and Figure 7 As shown, an opening 32 is provided at the front end of the housing 30, excluding the front stop 40. The opening 32 receives... Figure 7 The front pressing fixture 51 is shown in the diagonal section. The internal shape of the opening 32 is formed to be the same as or slightly larger than the external shape of the front pressing fixture 51. The opening 32 exposes a portion of the front end of the third wall portion 17C, a portion of the front end of the fourth wall portion 17D, and the front end of the second wall portion 17B forward. Thus, as Figure 6 As shown, the front pressing fixture 51 can be made to abut against the front end of the connecting cylinder 17 from the front.

[0086] like Figure 9 As shown, by inserting the front pressing fixture 51 into the opening 32 from the front and abutting against the connecting cylinder 17, the deformation of the terminal 12 and the housing 30 can be suppressed when the pressed part 46 of the sliding part 16 is pressed from the rear by the pressing fixture 45 to move it from the temporary locking position to the formal locking position.

[0087] like Figure 8 As shown, the housing 30 has a partition wall 34 that separates the upper storage portion 29 from the lower storage portion 29. The partition wall 34 extends rearward from the rear end of the storage portion 29. Figure 11 As shown, partition walls 35 extending in the front-to-back direction and protruding upwards and downwards are respectively provided on the upper and lower surfaces of the partition wall 34. Through the partition walls 35, the terminals 12 housed in each housing part 29 are electrically insulated from the terminals 12 adjacent in the left-to-right direction.

[0088] like Figure 11 As shown, temporary locking portions 36 protruding outward are provided on the left and right side walls of the housing 30 near the rear end, and formal locking portions 37 protruding outward are provided in a position in front of the temporary locking portions 36.

[0089] [Backholding Body]

[0090] like Figure 12 As shown, the rear retainer 31 is formed in the shape of a box with a front opening. The rear retainer 31 is formed by injection molding of insulating synthetic resin. The rear retainer 31 is fitted into the rear half of the housing 30. Lockable portions 38 are provided on the left and right side walls of the rear retainer 31 near the front end, capable of elastically engaging with the temporary locking portion 36 and the permanent locking portion 37 of the housing 30. The locked portions 38 are approximately door-shaped.

[0091] The rear retainer 31 is held in a temporary locked position relative to the housing 30 by being engaged by the temporary locking part 36 of the housing 30 and the locked part 38 of the rear retainer 31. Furthermore, the rear retainer 31 is held in a fully locked position relative to the housing 30 by being engaged by the permanent locking part 37 of the housing 30 and the locked part 38 of the rear retainer 31.

[0092] like Figure 3 As shown, the rear retainer 31 has a plurality of insertion holes 39 for inserting wires 11 arranged in a left-right direction and in two layers arranged vertically. The insertion holes 39 are located at positions corresponding to the receiving portion 29 of the housing 30. The inner diameter of the insertion holes 39 is set to be the same as or slightly larger than the outer diameter of the insulating covering portion 14 of the wires 11.

[0093] like Figure 8 As shown, the rear retainer 31 has a front opening at the front of the cover 41, which is embedded in the housing 30. A pair of protruding walls 42A and 42B are provided near the center of the rear end of the cover 41 in the vertical direction. These walls protrude forward into the cover 41 and are arranged at a vertical interval. The vertical interval between these protruding walls 42A and 42B is set to be the same as or slightly larger than the vertical thickness of the partition wall 34 of the housing 30.

[0094] like Figure 8 As shown, when the rear retainer 31 is held in a temporarily locked position relative to the housing 30, the pair of protruding walls 42A and 42B of the rear retainer 31 are located rearward than the rear end edge of the partition wall 34 of the housing 30. Figure 10 As shown, with the rear retainer 31 held in the locked position relative to the housing 30, the partition wall 34 of the housing 30 is inserted between the pair of protruding walls 42A and 42B of the rear retainer 31. This suppresses vertical misalignment of the rear retainer 31 relative to the housing 30.

[0095] [build]

[0096] like Figure 3 As shown, the cover 48 is formed in a box shape with an opening at the rear. The cover 48 is formed by injection molding of an insulating synthetic resin. Figure 1 As shown, the cover 48 can accommodate the housing 30 from the rear and the rear retainer 31, which is held in the correct locking position relative to the housing 30. Multiple ribs (not shown) protrude towards the interior of the cover 48 as it faces forward. This ensures that the housing 30 and the rear retainer 31 are held in the correct position.

[0097] like Figure 2 As shown, the cover 48 has insertion holes 49 arranged in a left-right direction and in two layers vertically, for inserting the opposite terminal from the front. The insertion holes 49 are located at positions corresponding to the receiving portion 29 of the housing 30. (As shown...) Figure 13 As shown, the cover 48 covers the opening 32 of the housing 30 from the front. Additionally, a guide portion 53 is provided on the inner wall of the insertion hole 49. The guide portion 53 is narrow in width as it faces from front to rear, making it easy for the other terminal to be inserted into the correct position of the terminal body 15.

[0098] [Example of the assembly process for connector 10]

[0099] Next, an example of the assembly process of the connector 10 in this embodiment will be described. The assembly process of the connector 10 is not limited to the following description.

[0100] The terminal body 15 and the sliding portion 16 are formed using a known method. The sliding portion 16 is assembled from the rear of the terminal body 15. The front edge of the sliding portion 16 abuts against the locking protrusion 28 of the terminal body 15 from the rear, and the sidewall of the sliding portion 16 expands and deforms. When the sliding portion 16 is further pressed forward, the sidewall of the sliding portion 16 returns to its original deformation, and the sliding portion 16 is temporarily locked by the locking portion 26 against the locking protrusion 28 of the terminal body 15. Thus, the sliding portion 16 is held in a temporarily locked position relative to the terminal body 15. Thus, the terminal 12 (see reference) is obtained. Figure 5 ).

[0101] The shell 30, the rear retainer 31, and the cover 48 are formed by injection molding of synthetic resin.

[0102] like Figure 8 As shown, terminal 12 is inserted into the receiving portion 29 of housing 30 from the rear, and rear retainer 31 is assembled to the rear end of housing 30 from the rear. The locking portion 38 of rear retainer 31 then elastically deforms and crosses the temporary locking portion 36 of housing 30. When rear retainer 31 is further pressed forward, the locking portion 38 returns to its original deformation and elastically locks into the temporary locking portion 36 of housing 30. Thus, rear retainer 31 is held in a temporary locked position relative to housing 30.

[0103] By peeling off the insulation covering 14 at the end of the wire 11, the core wire 13 of a predetermined length is exposed. The front end of the core wire 13 is then inserted from the rear into the insertion hole 39 provided at the rear end of the rear retainer 31.

[0104] When the wire 11 is pressed further forward, the front end of the core wire 13 protrudes forward from the insertion hole 39 of the rear retainer 31 and is guided into the interior of the sliding part 16 from the rear end of the sliding part 16. The core wire 13 is guided into the sliding part 16 by abutting against the core wire inlet 47 of the sliding part 16. When the wire 11 is pressed further forward, as... Figure 9 As shown, the front end of the core wire 13 enters the interior of the terminal body 15, thus passing through the space between the upper clamping portion 18A and the lower clamping portion 18B. In this state, the insulation covering portion 14 of the wire 11 is located within the insertion hole 39 of the rear retainer 31 (see reference). Figure 9 ).

[0105] Next, as Figure 9 As shown, the front pressing fixture 51 is inserted into the opening 32 from the front, so that the front pressing fixture 51 abuts against the front end of the connecting cylinder 17. In this state, when the pressing fixture 45 is pushed onto the pressed part 46 from the rear, the sliding part 16 moves forward relative to the terminal body 15. At this time, the locking protrusion 28 of the terminal body 15 and the temporarily locked part 26 of the sliding part 16 are released, and the side wall of the sliding part 16 expands and deforms by crossing the locking protrusion 28.

[0106] When the pressing jig 45 presses the pressed portion 46 further forward, the side wall of the sliding portion 16 returns to its original deformation, and the locking protrusion 28 of the terminal body 15 and the locked portion 27 of the sliding portion 16 elastically lock. Thus, the sliding portion 16 is held in the locked position relative to the terminal body 15.

[0107] When the sliding part 16 moves to the final locking position relative to the terminal body 15, the upper pressure part 25A of the sliding part 16 abuts against the upper clamping part 18A of the terminal body 15 from above and presses downward. Meanwhile, the lower pressure part 25B of the sliding part 16 abuts against the lower clamping part 18B of the terminal body 15 from below and presses upward. Thus, the core wire 13 is clamped from above and below by the upper clamping part 18A and the lower clamping part 18B, and the wire 11 and the terminal 12 are electrically connected (see reference). Figure 10 ).

[0108] With the core wire 13 clamped from above and below by the upper clamping portion 18A and the lower clamping portion 18B, the core wire 13 is held by the upper retaining protrusion 23A of the upper clamping portion 18A and the lower retaining protrusion 23B of the lower clamping portion 18B, thereby being held in a state that extends in the front-back direction and is bent in the vertical direction. Thus, the terminal 12 can securely hold the core wire 13 (see reference). Figure 10 ).

[0109] Next, when the rear retainer 31 is pressed forward, the locked portion 38 of the rear retainer 31 elastically deforms by crossing the locking portion 37 of the housing 30. When the rear retainer 31 is pressed further forward, the locking portion 37 and the locked portion 38 lock together. Additionally, the partition wall 34 of the housing 30 is inserted between a pair of protruding walls 42A and 42B of the rear retainer 31. Thus, the rear retainer 31 is held relative to the housing 30 in the locking position (see reference). Figure 10 ).

[0110] Finally, by housing the aforementioned housing 30 and rear retainer 31 within the cover 48, the assembly of the connector 10 is completed (see reference). Figure 1 ).

[0111] [Effects of this implementation method]

[0112] According to this implementation method, the following functions and effects are achieved.

[0113] The connector 10 of this embodiment includes: a terminal 12, which is connected to the core wire 13 located at the end of the wire 11 having a core wire 13; and a housing 30, which has a housing portion 29 for housing the terminal 12. The terminal 12 includes: a terminal body 15, which has a clamping portion 18; and a sliding portion 16, which is pressed from the rear to slide relative to the terminal body 15, thereby forming a state in which the core wire 13 is clamped by the clamping portion 18. The housing 30 has an opening 32, which exposes a portion of the front end of the terminal body 15 forward.

[0114] According to the above structure, by inserting the front pressing fixture 51 into the opening 32 from the front and making it abut against the terminal body 15, the deformation of the housing 30 and the terminal 12 can be suppressed when the sliding part 16 is pressed from the rear and made to slide, and the core wire 13 can be clamped and held by the sliding structure.

[0115] In this embodiment, the terminal body 15 has a connecting cylinder portion 17, the connecting cylinder portion 17 has a first wall portion 17A, and a contact piece 19 is provided on the first wall portion 17A to contact the opposite terminal inserted into the connecting cylinder portion 17.

[0120] According to the above structure, it becomes easy to insert the opposite terminal into the terminal body 15.

[0121] In this embodiment, when the sliding part 16 is inserted into the area where the clamping part 18 is provided, it can move in the front-back direction between a temporary locking position and a formal locking position that is forward of the temporary locking position. The sliding part 16 has a pressing part 25, which presses the clamping part 18 toward the core wire 13 at the formal locking position. The sliding part 16 is provided with a pressed part 46, which moves the sliding part 16 from the temporary locking position to the formal locking position by being pressed from the rear.

[0122] According to the above structure, by fixing the sliding part 16 to the fixed position, the core wire 13 can be held by the clamping part 18.

[0123] The connector 10 of this embodiment is manufactured in a method comprising: a terminal 12 for connecting to a core wire 13 located at the end of an electric wire 11 having a core wire 13; and a housing 30 having a housing portion 29 for housing the terminal 12. The terminal 12 comprises: a terminal body 15 having a clamping portion 18; and a sliding portion 16, which is pressed from the rear to slide relative to the terminal body 15, thereby forming a state in which the core wire 13 is clamped by the clamping portion 18. The housing 30 has an opening 32. The method of manufacturing connector 10 includes the following steps: housing terminal 12 in housing portion 29 of housing 30; inserting wire 11 with core wire 13 exposed into the interior of terminal body 15; pressing front jig 51 against a portion of front end of terminal body 15 exposed in opening 32 from the front; and clamping portion 18 of terminal body 15 with core wire 13 of wire 11 by pressing sliding portion 16 from the rear.

[0124] According to the above-described manufacturing method of connector 10, deformation of housing 30 and terminal body 15 can be suppressed, and the connecting core wire 13 can be clamped by a sliding structure.
