Description

[Technical Field]

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

[0002] A conventionally known stacked connector assembled by stacking multiple components is the connector described in JP 2012-186001 A (Patent Document 1 below). This connector includes a housing having terminal accommodating portions for accommodating terminal fittings, and a retainer having protrusions that engage with the terminal fittings when the connector is stacked on the housing. The housing is designed to be stacked on the housing, and includes protrusions similar to those of the retainer. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-186001 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above configuration, a space is provided between adjacent projections in the direction of arrangement of the terminal fittings. The housing is provided with a convex member that occupies part of the space between the projections, but there is still space between the projections where the convex member is not located.

[0005] In the above configuration, when a load is applied from the terminal to the protrusion, for example, when the wire connected to the terminal is pulled toward the rear of the connector, the protrusion is pressed by the terminal, causing it to become depressed and pushed out to the side of the terminal. That is, part of the material constituting the protrusion escapes into the space between the protrusions. This may reduce the shear cross-sectional area of ​​the protrusion sheared by the terminal. [Means for solving the problem]

[0006] The stacked connector of the present disclosure comprises a plurality of terminals, at least one first member, and at least one second member stacked on one side of the first member in a first direction, the first member having a plurality of terminal accommodating portions that accommodate the terminals, the second member having a base, a plurality of locking protrusions that protrude from the base to the other side in the first direction, and at least one connecting portion that connects adjacent locking protrusions, the terminals having locking portions that lock with the locking protrusions from one side in the second direction, and the connecting portion protruding to the other side in the first direction beyond the end of one side of the locking portion in the first direction. [Effects of the Invention]

[0007] According to the present disclosure, it is possible to provide a technique for improving the holding force of terminals in a stacked connector. [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 stacked connector of the present disclosure comprises a plurality of terminals, at least one first member, and at least one second member stacked on one side of the first member in a first direction, the first member having a plurality of terminal accommodating portions for accommodating the terminals, the second member having a base, a plurality of locking protrusions protruding from the base to the other side in the first direction, and at least one connecting portion connecting adjacent locking protrusions, the terminals having locking portions that lock with the locking protrusions from one side in the second direction, the connecting portion protruding to the other side in the first direction beyond the end of one side in the first direction of the locking portion.

[0011] When a load is applied to the locking protrusion by the locking portion of the terminal, the locking protrusion deforms, and a portion of the locking protrusion's material tends to escape in the direction of the arrangement of the terminals. In the above configuration, a connecting portion is provided to connect adjacent locking protrusions, and protrudes further to the other side in the first direction than the end of one side of the locking portion in the first direction. This prevents the portion of the locking protrusion's material pushed out by the locking portion from escaping in the direction of the arrangement of the terminals. This makes it easier to ensure the shear cross-sectional area of ​​the locking protrusion, thereby improving the terminal holding force.

[0012] (2) It is preferable that the connecting portion has a groove portion recessed from the connecting portion to one side in the first direction, and the first member has a protrusion portion arranged between adjacent terminal accommodating portions and accommodated in the groove portion.

[0013] According to this configuration, by providing the groove in the connecting portion and the protrusion in the first member, the creepage distance between the terminals can be increased.

[0014] (3) It is preferable that the grooves extend in a direction intersecting the second direction.

[0015] With this configuration, the projections and the inner walls of the grooves are locked together, making it difficult for the first member and the second member to become misaligned in the second direction.

[0016] (4) It is preferable that the second member includes a plurality of the connecting portions, and that the grooves are provided in each of the connecting portions so as to extend in the same direction.

[0017] This configuration allows the spacing between the grooves in the direction of arrangement of the terminals to be constant, and therefore the size of the connecting portions supporting each of the locking protrusions can be made constant at the height where the grooves are provided between the multiple locking protrusions, thereby allowing the retention force of each locking protrusion to be uniform.

[0018] (5) It is preferable that the second member has a receiving space between adjacent locking protrusions, the receiving space being arranged on one side of the connecting portion in the second direction, and the first member has a protrusion arranged between adjacent terminal accommodating portions and extending into the receiving space.

[0019] In the vicinity of the locking surface where the locking protrusion locks into the locking portion of the terminal, the height dimension of the terminal increases, which tends to reduce the creepage distance between adjacent terminals. According to the above configuration, the receiving space is disposed on one side of the connecting portion in the second direction, and the first member has a protrusion that enters the receiving space, making it easier to ensure the creepage distance between the terminals even in the area close to the locking surface.

[0020] (6) It is preferable that a plurality of the first members and a plurality of the second members are provided, and that at least one third member is provided, which is configured by integrating the first member and the second member.

[0021] With this configuration, the third member serves as both the first member and the second member, so that a multi-stage stacked connector can be constructed.

[0022] [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.

[0023] <Embodiment> An embodiment of the present disclosure will be described with reference to FIGS. 1 to 17. 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. In this embodiment, upward is an example of one side in the first direction, and downward is an example of the other side in the first direction. Forward is an example of one side in the second direction. Note that, for multiple identical components, only some of the components may be designated with reference numerals, and the reference numerals for the other components may be omitted.

[0024] [Stacked connector] 2 and 3, the stacked connector 10 according to this embodiment includes a plurality of terminals 20 and a housing 11 that accommodates the plurality of terminals 20. The housing 11 is composed of a lower housing 12, a middle housing 13, and an upper housing 14.

[0025] Terminal The terminal 20 is formed by pressing a conductive metal plate material or the like. As shown in Fig. 2, the terminal 20 includes a rectangular cylindrical connecting tube portion 21 located in the front, an electric wire connecting portion 23 located behind the connecting tube portion 21, and a neck portion 24 connecting the connecting tube portion 21 and the electric wire connecting portion 23. The electric wire connecting portion 23 is a portion that connects the terminal 20 to an electric wire (not shown). The electric wire connecting portion 23 includes a wire barrel 23A that is crimped onto a core wire of the electric wire, and an insulation barrel 23B that is crimped onto an insulating coating of the electric wire.

[0026] 7, a resilient contact piece 21A is provided inside the connecting tubular portion 21. When a mating terminal (not shown) enters the connecting tubular portion 21, the mating terminal 20 and the mating terminal are connected to each other by contacting the resilient contact piece 21A.

[0027] 5 and 6, a lance 21B protruding upward from the upper wall of the connecting tubular portion 21 is provided at a position near the front end of the upper wall. The lance 21B is adapted to engage with the inner wall of a lance hole 31A of the terminal accommodating portion 31, which will be described later. The upper portion of the rear end of the connecting tubular portion 21 serves as a locking portion 22. As will be described later, the locking portion 22 is adapted to engage with a locking projection 42 of the second member 40 from the front.

[0028] 2, the lower housing 12, the middle housing 13, and the upper housing 14 are made of insulating synthetic resin and are generally flat plates extending in the vertical direction. The middle housing 13 is stacked from above on the lower housing 12. The upper housing 14 is stacked from above on the middle housing 13, which is stacked on the lower housing 12.

[0029] A first lock receiving portion 12A, a second lock receiving portion 12B, and a lock recess 12C are provided on the side wall of the lower housing 12, recessed from the outer surface of the side wall. A first lock portion 13B is provided at the tip of an elastic piece 13A extending downward on the side of the middle housing 13. As shown in Fig. 8, the first lock receiving portion 12A and the first lock portion 13B are configured to lock together in the vertical direction.

[0030] 3, a second locking portion 14B is provided at the tip of an elastic piece 14A that extends downward from the top wall of the upper housing 14 on the rear side of the upper housing 14. The second lock receiving portion 12B and the second locking portion 14B are configured to be locked in the vertical direction.

[0031] As shown in Fig. 1, a downwardly protruding locking protrusion 14C is provided on the side wall of the upper housing 14. The locking protrusion 14C is adapted to engage with the inner wall of the locking recess 12C in the front-rear direction. Also, as shown in Fig. 7, the elastic piece 13A of the middle housing 13 is adapted to engage with the inner wall of the locking recess 12C in the front-rear direction.

[0032] 2 and 4, a front wall 12D extending in the up-down direction is provided at the front end of the lower housing 12. The front wall 12D is provided with a through hole 12E penetrating the front wall 12D in the front-rear direction. As shown in FIG. 7, the front wall 12D is configured to abut against the front end of the middle housing 13 and the front end of the upper housing 14 from the front. The through hole 12E communicates with the interior of a terminal accommodating portion 31, which will be described later. A mating terminal (not shown) of a mating connector that is fitted to the stacked connector 10 from the front side is inserted into the through hole 12E.

[0033] As shown in FIGS. 2 and 8 , the housing 11 includes a first member 30 and a second member 40 that are partial structures for holding the terminals 20. The second member 40 is stacked from above on the first member 30 in which the terminals 20 are housed, thereby holding the terminals 20 in the housing 11. The lower housing 12 includes the first member 30. The upper housing 14 includes the second member 40. The middle housing 13 includes the first member 30 and the second member 40. The first member 30 and the second member 40 are integrated into a third member 50. In other words, the middle housing 13 includes the third member 50. In this embodiment, the housing 11 includes two first members 30 and two second members 40. One first member 30 and one second member 40 are integrated to form one third member 50.

[0034] [First member, terminal housing] As shown in Figures 9 and 13, the first member 30 has a plurality of terminal accommodating sections 31 arranged side by side in the left-right direction (the direction in which the terminals 20 are arranged). An electric wire insertion hole 36 that communicates with the inside of the terminal accommodating section 31 is provided at the rear of each terminal accommodating section 31. An electric wire (not shown) is inserted through the electric wire insertion hole 36. A lance hole 31A that opens in the vertical direction is formed near the front end of the upper wall of the terminal accommodating section 31. As shown in Figures 5 and 6, the inner wall of the lance hole 31A is adapted to engage with the lance 21B of the terminal 20 accommodated in the terminal accommodating section 31.

[0035] An opening 31B that opens upward is formed near the center of the front and rear of the terminal accommodating portion 31. A locking protrusion 42 of the second member 40, which will be described later, is adapted to enter the terminal accommodating portion 31 through the opening 31B.

[0036] [Convex] As shown in FIGS. 9 and 13 , a partition wall 32 is disposed between adjacent terminal accommodating portions 31 in the left-right direction. The partition wall 32 is one of the walls constituting the opening 31B. As shown in FIG. 10 , a connecting portion receiving portion 33 is formed near the front end of the partition wall 32, recessed downward from the upper end of the partition wall 32. A protrusion 34 is formed inside the connecting portion receiving portion 33, rising upward from the bottom wall of the connecting portion receiving portion 33. The protrusion 34 is plate-shaped. The protrusion 34 is connected to the front and rear walls of the connecting portion receiving portion 33. The height of the protrusion 34 is approximately half the height of the connecting portion receiving portion 33. The protrusion 34 extends in a direction inclined relative to the front-rear direction. That is, the protrusion 34 extends in a direction intersecting the front-rear direction. Specifically, the protrusion 34 is inclined so that it is positioned leftward as it moves forward. The front end of the partition wall 32 disposed forward of the connecting portion receiving portion 33 is formed as a protrusion 35 .

[0037] [Second member, base] 11 and 14, the second member 40 includes a base 41, a plurality of locking projections 42 projecting downward from the base 41, and a plurality of connecting portions 43 connecting adjacent locking projections 42. The base 41 has a flat plate shape in the vertical direction. Note that, as shown in FIG. 8, in a third member 50 (intermediate housing 13) in which the first member 30 and the second member 40 are integrated, the base 41 is disposed below the terminal accommodating portion 31.

[0038] [Latching protrusion] As shown in Figures 11 and 14, the multiple locking protrusions 42 extend in the front-rear direction and are aligned in the left-right direction. As shown in Figures 5 and 6, the locking protrusions 42 enter the terminal accommodating portion 31 through the opening 31B. The locking protrusions 42 are shaped to fit along the terminal 20 from the rear end of the connecting tube portion 21 to the wire barrel 23A. The front lower end of the locking protrusions 42 is adapted to enter the inside of the neck portion 24. The front end surface of the locking protrusions 42 forms a locking surface 42A. The locking surface 42A is adapted to engage with the locking portion 22 of the terminal 20 in the front-rear direction.

[0039] [Connection part] As shown in FIG. 12, the connecting portion 43 extends downward from the base portion 41. The connecting portion 43 connects the locking surface 42A side (front side) of the locking projection 42. The dimension of the connecting portion 43 in the front-to-rear direction is approximately one-fourth of the dimension of the locking projection 42 in the front-to-rear direction. As shown in FIG. 7, the connecting portion 43 is accommodated in the connecting portion receiving portion 33. As shown in FIG. 8, the connecting portion 43 protrudes downward from the upper end portion 22A of the locking portion 22.

[0040] When a load is applied from the locking portion 22 to the locking protrusion 42, for example when the terminal 20 is pulled backward, the locking portion 22 pushes the locking protrusion 42, causing some of the material of the locking protrusion 42 to try to escape to the side (in the direction in which the terminals 20 are arranged) relative to the locking portion 22. However, in this embodiment, the connecting portion 43 that connects the locking protrusions 42 is provided so as to extend downward from the upper end portion 22A of the locking portion 22, thereby preventing some of the material of the locking protrusion 42 from escaping to the side of the locking portion 22. This makes it easier to ensure the shear cross-sectional area of ​​the locking protrusion 42 that engages with the locking portion 22, and improves the holding force of the terminal 20 compared to when the connecting portion 43 is not provided.

[0041] [Groove] As shown in FIG. 12, in this embodiment, the connecting portion 43 is formed with a groove 44 recessed upward from the lower surface of the connecting portion 43. The groove 44 is provided extending from the front end to the rear end of the connecting portion 43 and is open to the front and rear. The groove 44 extends in a direction inclined with respect to the front-to-rear direction. In other words, the groove 44 extends in a direction intersecting the front-to-rear direction. More specifically, the groove 44 is disposed more to the left as it moves forward. As shown in FIGS. 6 to 8, the groove 44 is configured to accommodate the protrusion 34.

[0042] If no groove 44 is formed in the connecting portion 43, the creepage distance D3 between the terminals 20 in the terminal accommodating portion 31 that are aligned in the left-right direction in the region where the connecting portion 43 is provided is shown by a dashed line in Fig. 17. If the terminals 20 and the terminal accommodating portion 31 are made smaller, it is considered that the provision of the connecting portion 43 makes it impossible to ensure a sufficient creepage distance D3 between the terminals 20. However, in this embodiment, the groove 44 and the protrusion 34 are provided, so that the creepage distance D1 between the terminals 20 can be made larger than the creepage distance D3 shown in Fig. 17, as shown in Fig. 15.

[0043] 7, the grooves 44 and the protrusions 34 extend in a direction inclined relative to the front-to-rear direction, so that the inner walls of the grooves 44 and the protrusions 34 are engaged with each other in the front-to-rear direction. This makes it difficult for the first member 30 and the second member 40 to shift relative to each other in the front-to-rear direction.

[0044] In this embodiment, the grooves 44 provided in each connecting portion 43 extend in the same direction. This allows the distance between the grooves 44 in the left-right direction to be constant. Therefore, as shown in FIG. 8, the size of the connecting portion 43 supporting each locking protrusion 42 can be made constant at the height at which the grooves 44 are provided between the multiple locking protrusions 42. This allows the holding force of each locking protrusion 42 to hold the terminal 20 to be uniform.

[0045] [Reception space] As shown in FIG. 12, the second member 40 of this embodiment has a receiving space 45 in front of the connecting portion 43. The receiving space 45 is disposed between adjacent locking protrusions 42. The receiving space 45 is defined by the lower surface of the base 41, the side surface 42B of the locking protrusion 42, and the front surface 43A of the connecting portion 43. By providing the receiving space 45, the front surface 43A of the connecting portion 43 is disposed in a recessed position relative to the locking surface 42A of the locking protrusion 42. The dimension of the receiving space 45 in the front-to-rear direction is approximately one-seventh of the dimension of the connecting portion 43 in the front-to-rear direction. As shown in FIG. 7, the protrusion 35 is disposed in the receiving space 45.

[0046] 5 and 6, the height dimension of the terminals 20 (measured upward from the bottom wall side of the terminal accommodating portion 31) is larger near the locking surface 42A. Specifically, the locking portion 22 at the rear end of the connecting tubular portion 21 is disposed in front of the locking surface 42A. The height dimension of the neck portion 24 is larger on the connecting tubular portion 21 side. In this embodiment, as shown in FIG. 7, the receiving space 45 and the protruding portion 35 are provided in an area close to the locking surface 42A. Therefore, as shown in FIG. 16, the provision of the receiving space 45 and the protruding portion 35 ensures a sufficient creepage distance D2 between the terminals 20 in an area close to the locking portion 22 of the terminals 20 (i.e., an area close to the locking surface 42A).

[0047] Furthermore, since the protruding portion 35 is disposed in the receiving space 45 where the connecting portion 43 is not provided, the protruding portion 35 can prevent the material of the locking projection 42 from escaping to the side of the locking portion 22 .

[0048] [Effects of the embodiment] According to the embodiment, the following actions and effects are achieved. The stacked connector 10 of the embodiment comprises a plurality of terminals 20, at least one first member 30, and at least one second member 40 stacked on the first member 30 from one side (above) in a first direction, the first member 30 having a plurality of terminal accommodating portions 31 for accommodating the terminals 20, the second member 40 having a base 41, a plurality of locking protrusions 42 protruding from the base 41 to the other side (below) in the first direction, and at least one connecting portion 43 connecting adjacent locking protrusions 42, the terminals 20 having locking portions 22 that lock with the locking protrusions 42 from one side (front) in the second direction, and the connecting portion 43 protruding to the other side in the first direction beyond the end (upper end 22A) on one side in the first direction of the locking portion 22.

[0049] When a load is applied to the locking protrusions 42 by the locking portions 22 of the terminals 20, the locking protrusions 42 deform, and some of the material of the locking protrusions 42 tries to escape in the alignment direction (left-right direction) of the terminals 20. In the above configuration, connecting portions 43 are provided to connect adjacent locking protrusions 42, and protrude further to the other side in the first direction than the end portions on one side of the locking portions 22 in the first direction. This prevents some of the material of the locking protrusions 42 pushed out by the locking portions 22 from escaping in the alignment direction of the terminals 20. This makes it easier to ensure the shear cross-sectional area of ​​the locking protrusions 42, thereby improving the holding force of the terminals 20.

[0050] In the embodiment, the connecting portion 43 has a groove portion 44 recessed to one side in the first direction from the connecting portion 43, and the first member 30 has a protrusion portion 34 arranged between adjacent terminal accommodating portions 31 and accommodated in the groove portion 44.

[0051] According to this configuration, by providing the grooves 44 in the connecting portion 43 and the protrusions 34 in the first member 30, the creepage distance between the terminals 20 can be increased.

[0052] In this embodiment, the groove 44 extends in a direction intersecting the second direction (front-rear direction).

[0053] With this configuration, the projections 34 and the inner walls of the grooves 44 are locked together, making it difficult for the first member 30 and the second member 40 to become misaligned in the second direction.

[0054] In the embodiment, the second member 40 includes a plurality of connecting portions 43, and each connecting portion 43 is provided with a groove portion 44 extending in the same direction.

[0055] With this configuration, the intervals between the grooves 44 in the arrangement direction of the terminals 20 can be made constant. Therefore, the size of the connecting portions 43 that support each locking projection 42 can be made constant at the height where the grooves 44 are provided between the multiple locking projections 42. Therefore, the holding force of each locking projection 42 to hold the terminal 20 can be made uniform.

[0056] In the embodiment, the second member 40 has a receiving space 45 between adjacent locking protrusions 42, and the receiving space 45 is arranged on one side in the second direction relative to the connecting portion 43, and the first member 30 has a protrusion 35 arranged between adjacent terminal accommodating portions 31 and entering the receiving space 45.

[0057] Near locking surface 42A where locking protrusion 42 locks with locking portion 22 of terminal 20, the height dimension of terminal 20 increases, which tends to reduce the creepage distance between adjacent terminals 20. According to the above configuration, receiving space 45 is disposed on one side in the second direction relative to connecting portion 43, and first member 30 has protruding portion 35 that enters receiving space 45, making it easier to ensure the creepage distance between terminals 20 even in the region close to locking surface 42A.

[0058] In the embodiment, a plurality of first members 30 and second members 40 are provided, and at least one third member 50 configured by integrating the first member 30 and the second member 40 is provided.

[0059] With this configuration, the third member 50 serves as both the first member 30 and the second member 40, so that a multi-stage stacked connector 10 can be constructed.

[0060] <Other embodiments> (1) In the above embodiment, the stacked connector 10 includes one third member 50, and the terminals 20 are arranged in two rows, one above the other. However, this is not limited to this, and the number of rows of terminals in the stacked connector may be one row or three or more rows. (2) In the above embodiment, the groove 44 is provided, but this is not limitative. As shown in FIG. 17, the groove does not have to be provided. (3) In the above embodiment, the receiving space 45 is provided, but this is not limiting, and the receiving space does not necessarily have to be provided. [Explanation of symbols]
