Description

[Technical field]

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

[0002] The connector disclosed in Patent Document 1 has a terminal unit in which an inner conductor is accommodated in a dielectric, and a housing having an accommodating chamber into which the terminal unit is inserted. When accommodating a plurality of terminal units in a housing, for example, a configuration like the multiple insertion connector disclosed in FIG. 1 of Patent Document 2 can be considered. The multiple insertion connector of Patent Document 2 includes an outer housing and insertion connectors arranged in parallel in two upper and lower stages in the outer housing. Each of the insertion connectors has an inner housing and a plurality of contact elements arranged in the inner housing. The contact elements are crimped and connected to two cores of the twisted pair cable. The multiple insertion connector of Patent Document 2 can be positioned in the vertical direction by arranging the insertion connectors arranged in two upper and lower stages with a shift to the left and right.

[0003] [Patent Document 1] JP 2018-152215 A [Patent Document 2] Special Publication No. 2015-528625 Summary of the Invention [Problem to be solved by the invention]

[0004] In a configuration in which the insertion type connectors arranged in two tiers, one above the other, are offset left and right, as in the connector of Patent Document 2, the size tends to increase in the left and right direction. If the insertion type connectors arranged in two tiers are to be aligned left and right in order to solve this problem, it becomes necessary to provide partition walls between the insertion type connectors, which tends to increase the size in the up and down direction. In addition, the multiple insertion type connectors arranged in the outer housing may each rattle within the outer housing. As a result, the insertion openings into which the mating contact elements are inserted may be misaligned between the multiple insertion type connectors arranged in parallel.

[0005] In view of the above, an object of the present disclosure is to provide a connector that can reduce the size of multiple terminal groups in the arrangement direction and prevent misalignment of insertion openings with respect to each other. [Means for solving the problem]

[0006] The connector of the present disclosure comprises: an inner module having a plurality of terminal groups each including a pair of terminals connected to a pair of conductive paths, an outer housing that accommodates the inner module; Equipped with the outer housing has only one accommodation chamber for accommodating the inner module, the inner module has an inner housing that is integrally formed to support the plurality of terminal groups, the inner housing has a front wall disposed in front of the terminal groups, The front wall is formed of a single member, and has insertion openings formed at positions corresponding to all of the terminals. Effect of the Invention

[0007] According to the present disclosure, it is possible to reduce the size of a plurality of terminal groups in the arrangement direction and prevent misalignment of the insertion openings with respect to each other. [Brief description of the drawings]

[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The connector of the present disclosure comprises: (1) An electrical connector comprising: an inner module having a plurality of terminal groups, each of which has a pair of terminals connected to a pair of conductive paths; and an outer housing that accommodates the inner module, wherein the outer housing has only one accommodating chamber that accommodates the inner module, and the inner module has an inner housing that is integrally formed to support the plurality of terminal groups, and the inner housing has a front wall that is positioned in front of the plurality of terminal groups, the front wall being constructed from a single member, and an insertion opening is formed at a position corresponding to each of the terminals. According to this configuration, the outer housing accommodates the inner module having multiple terminal groups in a single accommodating chamber, so there is no need to provide a wall (a wall that divides the space in the direction in which the multiple terminal groups are arranged) to separately accommodate each of the multiple terminal groups. This makes it possible to reduce the size of the multiple terminal groups in the direction in which they are arranged. Furthermore, according to this configuration, since the insertion openings corresponding to all the terminals are formed in a single member, it is possible to prevent the insertion openings from being misaligned with each other.

[0010] (2) The inner housing has a base member that separates the multiple terminal groups, and a pair of cover members that are assembled to the base member so as to sandwich the base member from both sides, each of the pair of cover members having a locking portion, and the base member has a first locking portion with which the locking portion of one of the pair of cover members locks, and a second locking portion with which the locking portion of the other cover member locks, and it is preferable that the first locking portion and the second locking portion have tapered surfaces that are inclined in opposite directions to each other. According to this configuration, it is possible to facilitate the assembly work of the pair of cover members which are assembled to the base member from opposite directions.

[0011] (3) The base member preferably has a guide portion provided along the installation direction of the cover member. According to this configuration, when the cover member is attached to the base member, the cover member can be guided by the guide portion.

[0012] (4) It is preferable that the engaging portion of the cover member is comb-shaped. According to this configuration, even if the inner housing is small, the cover member is engaged with the base member at multiple points, so that the cover member and the base member are unlikely to come off even if a force is applied in a direction that moves them apart from each other.

[0013] (5) It is preferable that the first and second locking portions be disposed in a positional relationship that is point symmetrical with respect to each other in a front view from the front. According to this configuration, the pair of cover members can be made of a common member.

[0014] (6) The inner housing preferably has a base member having a partition portion that separates the multiple terminal groups, and a pair of cover members that are assembled to the base member so as to sandwich the base member from both sides, and the cover members preferably have a locking portion that engages with the base member, and a deflection control portion that is connected to the locking portion and is positioned between the partition portion and the electric wires connected to the terminal groups. According to this configuration, it is possible to restrict bending of the electric wires toward the side opposite to the partition portion.

[0015] (7) The terminal group preferably has a crimping portion to be crimped to the electric wire, and the cover member preferably has a fitting hole in front of the flexure restricting portion, into which the crimping portion fits. According to this configuration, the crimping portion fits into the fitting hole, so that the electric wires connected to the terminal group can be prevented from falling off rearward.

[0016] [Details of the embodiment of the present disclosure] [Example 1] A first embodiment of the connector of the present disclosure will be described with reference to Figures 1 to 14. In this first embodiment, the up-down direction is defined as the direction shown in Figures 1 to 4 and 7 to 13, as upward and downward.

The left and right directions are defined as the left and right directions when the connector is viewed from the front, as left and right, respectively.

[0017] (Connector configuration) A connector 10 according to the first embodiment shown in Fig. 1 is configured as a branch connector to be connected to, for example, a trunk harness. As shown in Fig. 2, the connector 10 includes an inner module 11, an outer housing 12, and a retainer 13. The inner module 11 is accommodated in the outer housing 12. As shown in Fig. 3, the inner module 11 includes an inner housing 21 and a pair of terminal groups 22. The number of terminal groups 22 is the same as the number of systems of the conductive paths that make up the trunk harness.

[0018] As shown in Fig. 3, the inner housing 21 includes one base member 31 made of a single component, and a pair of cover members 32. The inner housing 21 is integrally formed by assembling the pair of cover members 32 to the base member 31 from both the top and bottom of the base member 31. That is, in this embodiment 1, the up-down direction corresponds to the assembling direction of the base member 31. The base member 31 and the cover members 32 are components made of an insulating material such as synthetic resin. The inner housing 21 supports the pair of terminal groups 22, and is integrally formed as the inner module 11 together with the pair of terminal groups 22.

[0019] 4 and 5, the base member 31 has a partition portion 40 that separates the pair of terminal groups 22. The partition portion 40 is plate-shaped and is disposed with its plate surface facing in the up-down direction. The partition portion 40 extends in the front-rear direction.

[0020] As shown in Figures 4 and 5, the base member 31 has a first locking receiving portion 41 and a second locking receiving portion 42 provided on both the left and right sides of the partition portion 40. The first locking receiving portion 41 and the second locking receiving portion 42 extend upward and downward from both the left and right sides of the partition portion 40, respectively. The first locking receiving portion 41 and the second locking receiving portion 42 are alternately arranged in the front-to-rear direction. The first locking receiving portion 41 and the second locking receiving portion 42 are arranged in a positional relationship that is point-symmetrical to each other when viewed from the front (a direction perpendicular to the assembly direction of the cover member 32 to the base member 31).

[0021] As shown in Figures 4 and 12, the first locking receiving portions 41 on both the left and right sides have a first tapered surface 41A on their outer surfaces that is inclined along the assembly direction. As shown in Figures 4 and 12, the second locking receiving portions 42 on both the left and right sides have a second tapered surface 42A on their outer surfaces that is inclined along the assembly direction. The first tapered surface 41A is inclined upwardly and inwardly in the left-right direction, and the second tapered surface 42A is inclined downwardly and inwardly in the left-right direction. The first tapered surface 41A and the second tapered surface 42A intersect when viewed from the front.

[0022] The first lock receiving portion 41 has a first lock receiving surface 41B as shown in Figures 4 and 12. The second lock receiving portion 42 has a second lock receiving surface 42B as shown in Figures 4 and 12. The first lock receiving portion 41 and the second lock receiving portion 42 are offset from each other in the vertical direction, and the claw portion 55 of the cover member 32 is fitted into the first lock receiving surface 41B and the second lock receiving surface 42B formed by this offset.

[0023] 4 and 5, the base member 31 has a crimp ring fitting groove 43 into which the crimp ring 76 fits. The crimp ring fitting groove 43 is formed on both the upper and lower sides of the partition portion 40 and extends in the left-right direction. The crimp ring fitting groove 43 is disposed between the first lock receiving portion 41 and the second lock receiving portion 42 which are aligned in the front-rear direction.

[0024] 4 and 5, the base member 31 has guide portions 44 provided along the installation direction of the cover member 32. The guide portions 44 are provided on the first tapered surface 41A or the second tapered surface 42A. The guide portions 44 are provided on all of the first tapered surfaces 41A and second tapered surfaces 42A on both the left and right sides.

[0025] As shown in Figures 4 and 5, the base member 31 has terminal accommodating grooves 46 formed on both the upper and lower sides of the partition portion 40. The terminal accommodating groove 46 is long in the front-rear direction and opens outward in the up-down direction. Two terminal accommodating grooves 46 are provided side by side on the left and right. The two side by side terminal accommodating grooves 46 are partitioned by the partition portion 40, a first locking receiving portion 41 and a second locking receiving portion 42 on both the left and right sides, and a partition wall 47 disposed between the two side by side terminal accommodating grooves 46.

[0026] As shown in Figs. 4 and 5, the base member 31 has a front wall 48 in front of the terminal accommodating grooves 46. The front wall 48 has a rectangular shape when viewed from the front. The front wall 48 is continuous with the front end of the partition portion 40. The front wall 48 is formed with a plurality of insertion openings 48A penetrating the front wall 48 in the front-rear direction. The plurality of insertion openings 48A are provided corresponding to all of the terminal accommodating grooves 46, respectively. In other words, the plurality of insertion openings 48A are provided corresponding to all of the terminals 60 to be disposed in all of the terminal accommodating grooves 46. The entire front wall 48 is formed of a single member.

[0027] As shown in FIG. 3, the cover member 32 has a plate-shaped cover body 50, locking portions 51 extending upward or downward from both the left and right sides of the cover body 50, and a crimp ring restricting portion 52.

[0028] The cover body 50 is elongated in the front-rear direction and is disposed with its plate surface facing the up-down direction. A front-side retaining recess 50A and a rear-side retaining recess 50B are formed on the inner surface of the cover body 50. The rear-side retaining recess 50B is disposed behind the front-side retaining recess 50A.

[0029] As shown in FIG. 3, the locking portion 51 has a comb shape protruding upward or downward from both the left and right sides of the cover body 50. The locking portion 51 has locking arms 54 extending upward or downward from both the left and right sides of the cover body 50. A plurality of locking arms 54 are provided at intervals along the front-rear direction. The locking arms 54 are plate-shaped and are arranged with their plate surfaces facing the left-right direction. A claw portion 55 is provided at the tip of the locking arm 54. The locking arm 54 has a base end as a fixed end and the tip side is flexibly deformed. The locking arms 54 are provided alternately left and right in the front-rear direction.

[0030] As shown in FIG. 8, the crimping ring restricting portion 52 vertically sandwiches the crimping ring 76 between itself and the bottom surface of the crimping ring fitting groove 43 to restrict movement in the vertical direction.

[0031] 8, the cover body 50 has a flexure restriction portion 56 at the rear end portion. The flexure restriction portion 56 is connected to the locking portion 51, more specifically, to the locking arm 54. The flexure restriction portion 56 extends in the left-right direction from the base end portion of the locking arm 54, and is disposed on the opposite side of the partition portion 40 with the electric wire 70 sandwiched therebetween.

[0032] 8, the cover body 50 has a fitting hole 57 in front of the flexure restriction portion 56. In the fitting hole 57, a crimping portion 76A of a crimping ring 76 fits.

[0033] As shown in FIG. 3, the terminal group 22 includes a pair of terminals 60. The terminal 60 has an elongated shape in the front-rear direction as a whole. A square tube portion 61 is formed at the front end of the terminal 60, and an open-barrel-shaped terminal-side crimping portion 62 is formed at the rear end of the terminal 60. The terminal-side crimping portion 62 is fixed to the divided portion 72 of the conductive path 71 by crimping so as to be conductive. Although not shown in the figure, the pair of conductive paths 71 are configured as twisted pair wires. A front stabilizer 61A protruding in a direction perpendicular to the front-rear direction is formed at the front end of the square tube portion 61. A rear stabilizer 61B protruding in a direction perpendicular to the front-rear direction is formed at the rear end of the square tube portion 61.

[0034] As shown in FIG. 3, the terminal side crimping portion 62 is fixed to the dividing portion 72 of the conductive path 71 so as to be conductive. The branching portion of each conductive path 71 is the dividing portion 72 which divides each conductive path 71. At the dividing portion 72, the insulating coating 73 is removed to expose the conductor 74. The pair of conductors 74 covered with the insulating coating 73 are collectively surrounded by the sheath 75 to form the electric wire 70. The electric wire 70 includes a crimping ring 76 attached to an end of the sheath 75. The crimping ring 76 has a crimping portion 76A which is crimped to a part of the dividing portion 72, and a positioning portion 76B which protrudes outward in the left-right direction from the dividing portion 72. The terminal 60 fixed to the conductive path 71 extends in a straight line from the dividing portion 72 of the conductive path 71.

[0035] As shown in Fig. 7, the terminals 60 are accommodated in the terminal accommodating grooves 46 of the base member 31. As shown in Fig. 10, the upper terminal 60 is supported by the inner housing 21 in an orientation that is upside down relative to the lower terminal 60.

[0036] The outer housing 12 is a single rectangular cylindrical part made of an insulating material such as synthetic resin. As shown in FIG. 2, the outer housing 12 has a pair of symmetrical side walls 81, a bottom wall 82 formed by connecting the lower edges of the left and right side walls 81, and an upper wall 83 formed by connecting the upper edges of the left and right side walls 81. The outer housing 12 has only one accommodation chamber 84 for accommodating the inner module 11. The accommodation chamber 84 is provided inside the outer housing 12. Both front and rear ends of the accommodation chamber 84 are open to the outside of the outer housing 12. The inside of the accommodation chamber 84 is not partitioned by a partition wall or the like.

[0037] As shown in Fig. 2, a first locked portion 81A and a second locked portion 81B are provided on the outer surfaces (surfaces opposite to the other side wall portion 81) of the left and right side wall portions 81. The first locked portion 81A and the second locked portion 81B protrude outward in the left-right direction (opposite to the other side wall portion 81). The first locked portion 81A is provided below and spaced apart from the second locked portion 81B. The first locked portion 81A and the second locked portion 81B are locked by a retainer side locking portion 13E of the retainer 13 described later.

[0038] 13, an elastic retaining piece 85 is formed on the inner surface of the upper wall portion 83. The elastic retaining piece 85 is adapted to be elastically displaceable in the vertical direction relative to the upper wall portion 83. The outer housing 12 is formed with a locking arm 86 that covers the outer surface of the upper wall portion 83 with a gap therebetween. The locking arm 86 extends rearward from the front end portion of the outer housing 12 in a cantilever shape and is elastically deformable.

[0039] As shown in FIG. 2, the retainer 13 includes a bottom wall 13A and a pair of side walls 13B. The pair of side walls 13B rise upward from both the left and right ends of the bottom wall 13A. The upper surface of the bottom wall 13A is provided with a retainer side protrusion 13C that protrudes upward. The inner surface (surface on the other side wall 13B side) of the side wall 13B is provided with a retainer side recess 13D that is recessed outward (opposite the other side wall 13B side). The upper end of the retainer side recess 13D is a retainer side locking portion 13E that is hooked onto the first locked portion 81A or the second locked portion 81B. The retainer side locking portion 13E is locked to the first locked portion 81A, so that the retainer 13 is provisionally locked to the outer housing 12. When the retainer side locking portion 13E is locked to the second locked portion 81B, the retainer 13 is brought into a fully locked state with respect to the outer housing 12.

[0040] (Connector assembly) Next, the assembly of the connector 10 will be described. As shown in Fig. 7, the terminal group 22 connected to the electric wires 70 is assembled to the base member 31. The terminals 60 are inserted into the openings of the terminal accommodating grooves 46 in a position (the position shown in Fig. 3) along the extension direction (front-rear direction) of the terminal accommodating grooves 46. The positioning portion 76B of the crimping ring 76 is fitted into the crimping ring fitting groove 43.

[0041] Next, as shown in Fig. 8, the cover member 32 is attached to the base member 31 from above. When the cover member 32 is attached to the base member 31, the locking portion 51 is slid along the guide portion 44 on the first tapered surface 41A of the first lock receiving portion 41 to be locked to the first lock receiving surface 41B. This allows the cover member 32 to be attached to the base member 31. In the same manner, the other cover member 32 is attached to the base member 31 as shown in Fig. 9.

[0042] In a state where the cover member 32 is assembled to the base member 31, as shown in FIG. 8, the positioning portion 76B of the crimping ring 76 is disposed between the bottom surface of the crimping ring fitting groove 43 and the crimping ring restricting portion 52 of the cover member 32, and the movement in the up-down direction is restricted. Also, as shown in FIG. 10, the front stabilizer 61A of the terminal 60 fits into the front retaining recess 50A of the cover member 32, and the rear stabilizer 61B of the terminal 60 fits into the rear retaining recess 50B of the cover member 32. Also, as shown in FIG. 11, the deflection restricting portion 56 of the cover member 32 is disposed on the outer side of the electric wire 70 in the up-down direction. Since the deflection restricting portion 56 is connected to the locking portion 51, the movement of the electric wire 70 in the outward direction in the up-down direction is restricted. Also, as shown in FIG. 11, the crimping portion 76A of the crimping ring 76 fits into the fitting hole 57 of the cover member 32. This prevents the terminal group 22 from falling out rearward. By assembling the pair of cover members 32 to both sides of the base member 31 in this manner, the inner module 11 is completed.

[0043] Next, the inner module 11 is inserted from the rear into the accommodation chamber 84 of the outer housing 12. Before inserting the inner module 11, the retainer 13 is placed in a provisionally locked state with respect to the outer housing 12. During the insertion process, the elastic retaining pieces 85 are elastically deformed due to interference with the inner module 11 (front wall 48 of the base member 31), and then, as the insertion proceeds further, they elastically return to their original shape and lock (primarily lock) against the rear surface of the front wall 48.

[0044] After the inner module 11 is inserted into the outer housing 12 in the correct position, the retainer 13 is brought into a fully locked state with respect to the outer housing 12, as shown in Fig. 13. The retainer side protrusion 13C is locked (secondarily locked) with the outer recess 59 of the cover member 32. This prevents the inner module 11 from coming out of the outer housing 12.

[0045] FIG. 14 shows an application example of the connector 10. As shown in FIG. 14, the connector 10 is connected to the middle of a trunk harness formed of a pair of conductive paths 71. The connector 10 has a function of branching a communication circuit 91 from the trunk harness. The communication circuit 91 is formed as a printed circuit on a circuit board 92. A board connector (not shown) is mounted on the circuit board 92. The board connector has two pairs of tab-shaped branch side terminals 93 attached to a board side housing (not shown) fixed to the circuit board 92. The branch side terminals 93 are connected to the communication circuit 91. When the connector 10 is fitted to the board connector, the communication circuit 91 is branched off from the trunk harness.

[0046] (Effects of this embodiment) As described above, according to the connector 10 of the present disclosure, the outer housing 12 is configured to accommodate the inner module 11 having the multiple terminal groups 22 in a single accommodation chamber 84, and therefore there is no need to provide a wall (a wall that divides the space in the arrangement direction of the multiple terminal groups 22) that divides the space in the accommodation chamber 84 to accommodate the multiple terminal groups 22 separately. Therefore, the size of the connector 10 in the arrangement direction of the multiple terminal groups 22 can be reduced. Furthermore, according to this configuration, the insertion openings 48A corresponding to all the terminals 60 are formed in the front wall 48, which is a single member, and therefore it is possible to prevent the insertion openings 48A from being misaligned with each other.

[0047] Furthermore, the first tapered surface 41A of the first lock receiving portion 41 and the second tapered surface 42A of the second lock receiving portion 42 are inclined along the assembly direction of the cover member 32 in a front view seen from the front, and the inclination directions are opposite to each other. This makes it possible to easily assemble the pair of cover members 32 that are assembled to the base member 31 from opposite directions.

[0048] Furthermore, the base member 31 has a guide portion 44 provided along the assembly direction of the cover member 32. Therefore, when the cover member 32 is assembled to the base member 31, the cover member 32 can be guided by the guide portion 44.

[0049] Furthermore, the locking portion 51 is comb-shaped. Therefore, even if the inner housing 21 is small, the cover member 32 is locked to the base member 31 at multiple points, so that the cover member 32 and the base member 31 are unlikely to come off even if a force is applied in a direction in which they move away from each other.

[0050] Furthermore, the first lock receiving portion 41 and the second lock receiving portion 42 are disposed in a positional relationship that is point symmetrical with each other in a front view from the front. Therefore, the pair of cover members 32 can be formed as a common member.

[0051] Furthermore, the cover member 32 has a locking portion 51 that is locked to the base member 31, and a flexure restricting portion 56 that is connected to the locking portion 51 and is positioned so as to sandwich the electric wires 70 connected to the terminal group 22 between the locking portion 51 and the partition portion 40. Therefore, flexure of the electric wires 70 in the opposite direction to the partition portion 40 can be restricted.

[0052] Furthermore, the terminal group 22 has a crimping portion 76A that is crimped to the electric wire 70, and the cover member 32 has a fitting hole 57 into which the crimping portion 76A fits, in front of the deflection restricting portion 56. By fitting the crimping portion 76A into the fitting hole 57, it is possible to prevent the electric wire 70 connected to the terminal group 22 from coming loose backward.
