Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the case of Patent Document 1, after insert molding, since the periphery of the resin filling hole engages with the gap resin portion, it is possible to make it difficult for the connection plate portion to float. However, since resin filling holes are formed in the connection plate portion, there is a concern that the resin may creep up onto the welding surface during insert molding. In this case, since resin exists on the welding surface of the connection plate portion, there is a possibility that contact failures or the like may occur.

[0005] An object of the present disclosure is to provide a connector that can hardly cause the bus bar to float and can hardly cause contact failures in the bus bar.

Means for Solving the Problems

[0006] A connector that solves the above problem has a connector body in which a busbar, which is electrically connected to a mating terminal, is integrally formed with resin by molding, and the busbar includes a protruding contact portion formed by bending a part of the busbar into a protruding shape as a contact with the mating terminal, and an engaging portion formed on the inner surface of the protruding contact portion so as to be embedded in the body of the connector body. [Effects of the Invention]

[0007] This disclosure makes it less likely for the busbar to lift up and less likely for contact failures to occur in the busbar. [Brief explanation of the drawing]

[Figure 9] Figure 9 is a magnified perspective view of a busbar in another example. [Modes for carrying out the invention]

[0009] First, the embodiments of this disclosure will be listed and described. [1] The connector of the present disclosure comprises a connector body in which a busbar, which is electrically connected to a mating terminal, is integrally formed with resin by molding, wherein the busbar includes a protruding contact portion formed by bending a part of the busbar into a protruding shape, and an engaging portion formed on the inner surface of the protruding contact portion so as to be embedded in the body of the connector body.

[0010] This configuration allows the busbar to be securely fixed to the body by embedding the engaging portion on the inner surface of the protruding contact portion into the raised portion of the body that fits inside the protruding contact portion. This makes it difficult for the busbar to lift away from the body. Furthermore, by providing an engaging portion on the busbar and embedding it in the body as a measure to prevent the busbar from lifting, it is not necessary to form a hole in the busbar. Therefore, the resin does not rise onto the upper surface of the busbar during insert molding. Consequently, it is also possible to reduce the likelihood of contact failure in the busbar.

[0011] [2] In the above [1], the engaging portion is formed on the busbar at the same time as the protruding contact portion when the protruding contact portion is formed on the busbar. With this configuration, when processing the busbar to form the protruding contact portion, it is possible to form the protruding contact portion and the engaging portion at the same time. Thus, the busbar manufacturing process can be simplified.

[0012] [3] In the above [1] or [2], the protruding contact portion has a recess on its inner surface formed by thinning the thickness of a part of the busbar, and the engaging portion is formed on at least a part of the periphery of the recess. With this configuration, when forming the protruding contact portion and the engaging portion on the busbar, it is only necessary to form a recess on the back surface of the busbar and then bend the portion of the busbar that includes the recess. Thus, in this respect, busbar manufacturing is simple.

[0013] [4] In [3] above, the recess is formed in a shape having a long-hole-shaped opening. In the recess, a pair of width-direction opening edges extending in the width direction of the bus bar are provided so as to face each other, and a pair of width-crossing-direction opening edges extending in a direction crossing the width-direction opening edges are provided so as to face each other. The engaging portion is formed at least on the width-direction opening edges. According to this configuration, it is possible to make the shape of the recess a simple shape having a long-hole-shaped opening. Also, since the pair of engaging portions are provided so as to face each other, it is possible to form an embedding shape in which the body is sandwiched from both sides by the pair of engaging portions. Therefore, it is also possible to firmly embed the engaging portion in the body.

[0014] [5] In any one of [1] to [4] above, a plurality of sets of the protruding contact portion and the engaging portion are provided on the bus bar. According to this configuration, it is possible to fix the bus bar to the body by the plurality of engaging portions, which further contributes to preventing the bus bar from lifting.

[0015] [6] In any one of [1] to [5] above, the protruding contact portion is disposed at a position closer to the tip of the bus bar. According to this configuration, it is possible to make it difficult for the bus bar to lift from the tip, which further contributes to preventing the bus bar from lifting.

[0016] [7] In any one of [1] to "6" above, the bus bar has a bus bar main body portion at least partially embedded in the body, and a bus bar tip portion exposed from the body and formed in a shape bent in a direction crossing the extending direction of the bus bar main body portion. The protruding contact portion and the engaging portion are provided on the bus bar tip portion. According to this configuration, it is possible to make it difficult for the bus bar tip portion to lift from the body.

[0017] [8] In [7] above, the body has a seat portion for placing the tip of the bus bar, and the tip of the bus bar is formed to have the same width and depth as the seat portion at the portion placed on the seat portion. According to this configuration, in the case where the tip of the bus bar has a shape for placing on the seat portion of the body, for example, it may be in a situation where it can only be formed with an area similar to the seat portion. However, since an engaging portion is provided at the tip of the bus bar, even if a size limitation occurs at the tip of the bus bar, it is possible to firmly fix the tip of the bus bar to the seat portion.

[0018] [9] In [7] above, the tip of the bus bar is formed in a rectangular plate shape, and when a plurality of the protruding contact portions are provided, they are arranged side by side in the longitudinal direction of the tip of the bus bar. According to this configuration, it is possible to arrange the protruding contact portions at suitable positions in a well-balanced manner with respect to the tip of the bus bar formed in a rectangular plate shape.

[0019]

[10] In any one of [1] to [9] above, the mating terminal has a plate-like portion that contacts the bus bar. According to this configuration, even in a structure where the plate-like portion of the mating terminal contacts the bus bar, since the contact tip of the plate-like portion is the protruding contact portion, it is possible to facilitate these contacts.

[0020]

[11] In any one of [1] to

[10] above, when a plurality of the bus bars are provided, they are arranged side by side in the plane direction of the connector body. According to this configuration, it is possible to make the shape of the connector body a simple shape in which the bus bars are arranged side by side in the plane direction of the connector body.

[0021] [Details of Embodiments of the Present Disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these examples, and is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In each drawing, for convenience of explanation, a part of the configuration may be shown exaggerated or simplified. Also, the dimensional ratios of each part may be different from the actual ones.

[0022] (Connector 1) As shown in Figure 1, connector 1 comprises a connector body 3 that is electrically connected to mating connector 2. In this example, for example, connector 1 is a male connector and mating connector 2 is a female connector. Connector 1 is attached to a mounting site (not shown) by passing a fastener (not shown) through a collar 6 inserted into a hole 5 in the mounting piece 4 and fixing this fastener to the mounting site (not shown). Connector 1 is fitted with a sealing member 7 that seals the gap between it and mating connector 2. Connector 1 is preferably, for example, for automotive use.

[0023] (Connector body 3) As shown in Figure 1, the connector body 3 comprises a plurality (six in this example) of busbars 10. The connector body 3 is a resin molded product in which the busbars 10 are integrally formed with resin by molding. In this example, the connector body 3 is integrally formed with resin by molding, for example, by setting a plurality of busbars 10 in a mold and pouring resin into it. In this example, the connector body 3 has a plurality of busbars 10 and a resin body 11 in which these busbars 10 are integrated. The mounting piece 4 is formed on the body 11.

[0024] (Mating terminal 13) As shown in Figure 2, the mating connector 2 has multiple mating terminals 13 that are electrically connected to each busbar 10 (only one is shown in Figure 2). The mating terminal 13 has a plate-shaped portion 14 that contacts the busbar 10. The mating terminal 13 is biased toward the busbar 10 by a biasing portion 15, such as a spring. Therefore, the mating terminal 13 is pressed against the busbar 10 by a predetermined contact pressure due to the biasing force of the biasing portion 15.

[0025] (Bus bar 10) As shown in Figure 1, the multiple busbars 10 are arranged in a line in the planar direction of the connector body 3 (the XY axis plane direction in Figure 1). In this example, the six busbars 10 are designated as the first busbar 10a, the second busbar 10b, the third busbar 10c, the fourth busbar 10d, the fifth busbar 10e, and the sixth busbar 10f, in order from left to right on the page.

[0026] As shown in Figure 2, the busbar 10 has a busbar main body portion 17, at least a part of which is embedded in the body 11, and a busbar tip portion 18 that is exposed from the body 11 and is formed in a shape that is bent in a direction (X-axis direction in Figure 2) that intersects the extending direction (Z-axis direction in Figure 2) of the busbar main body portion 17. In this example, the busbar main body portion 17 and the busbar tip portion 18 are formed by bending at a right angle.

[0027] As shown in Figure 3, the busbar tip 18 is formed, for example, in the shape of a rectangular plate. The body 11 has a seat 19 on which the busbar tip 18 rests. The busbar tip 18 is formed to have the same width and depth as the seat 19 in the portion that rests on the seat 19. The width is the size in the Y-axis direction as shown in Figure 3. The depth is the size in the X-axis direction as shown in Figure 3.

[0028] The connector body 3 has a support portion 20 that supports the bus bar 10 by the thickness of the body 11. The support portion 20 supports the bus bar body portion 17 by, for example, sandwiching the bus bar body portion 17 from both sides with the resin material of the body 11.

[0029] As shown in Figure 4, the base ends 21 of each busbar 10 are arranged in the width direction (Y-axis direction in Figure 4) of the connector body 3, with the base ends 21a of the first busbar 10a, the second busbar 10b, and the third busbar 10c group, and the base ends 21b of the fourth busbar 10d, the fifth busbar 10e, and the sixth busbar 10f group being aligned. The shape of the busbar body portion 17 of each busbar 10 is formed in such a way that the base ends 21a and 21b can be arranged as described above. A sealing member 22 is attached to the connector body 3 to seal the gap between the connector 1 and the mounting destination (not shown).

[0030] (Protruding contact portion 24) As shown in Figures 2 and 3, the busbar 10 is provided with a protruding contact portion 24 formed by bending a part of the busbar 10 into a protruding shape, which serves as a contact point with the mating terminal 13. In this example, the protruding contact portion 24 is provided at the tip portion 18 of the busbar. The protruding contact portion 24 is formed in an elongated shape that extends in the width direction (Y-axis direction in Figure 2) of the busbar 10 in a plan view, for example.

[0031] Multiple (two in this example) protruding contact portions 24 are provided on the busbar 10, for example. When there are two protruding contact portions 24, one is designated as the first protruding contact portion 24a and the other as the second protruding contact portion 24b. When multiple protruding contact portions 24 are provided, they are arranged in a line along the longitudinal direction (X-axis direction in Figure 2) of the busbar tip portion 18. It is preferable that the protruding contact portions 24 be positioned closer to the tip of the busbar 10, for example. Specifically, of the first protruding contact portion 24a and the second protruding contact portion 24b, the first protruding contact portion 24a is positioned closer to the tip of the busbar tip portion 18.

[0032] As shown in Figure 2, the protruding contact portion 24 is formed in a semi-circular shape, for example, in a cross-sectional view. Thus, the busbar tip portion 18 has a recessed portion 25 formed on the inner surface of the busbar 10 by providing the protruding contact portion 24. The recessed portion 25 is, for example, a recessed portion created when the protruding contact portion 24 is formed by bending. As a method for forming the protruding contact portion 24, for example, press working can be used as a type of bending process.

[0033] (Anti-floating structure for the protruding contact portion 24) As shown in Figures 2 and 5, the bus bar 10 includes an engaging portion 27 formed on the inner surface of the protruding contact portion 24 so as to be embedded in the body 11 of the connector body 3. The engaging portion 27 is, for example, an undercut portion that protrudes in a direction intersecting the mold opening and closing direction. The engaging portion 27 is formed on the bus bar 10 at the same time as the protruding contact portion 24 when the protruding contact portion 24 is formed on the bus bar 10. Multiple sets of the protruding contact portion 24 and engaging portion 27 are provided on the bus bar 10 (two sets in this example). In this example, the engaging portion 27 is provided on the bus bar tip 18.

[0034] The engaging portion 27 is provided, for example, in a recess 28 formed on the inner surface of the protruding contact portion 24. The recess 28 is formed, for example, by reducing the thickness of a part of the busbar 10. The recess 28 is located, for example, approximately in the center of a recessed portion 25 provided on the back surface of the protruding contact portion 24.

[0035] As shown in Figure 5, the recess 28 is formed in a shape having, for example, an elongated opening. In this case, the recess 28 is provided with a pair of widthwise opening edges 29 that extend in the width direction of the busbar 10 and are arranged opposite each other. The recess 28 is also provided with a pair of width-intersecting opening edges 30 that extend in a direction intersecting the widthwise opening edges 29 (in this example, orthogonal directions) and are arranged opposite each other. The engaging portion 27 is formed on at least a part of the periphery of the recess 28. For example, it is preferable that the engaging portion 27 is formed on at least the widthwise opening edges 29 of the periphery of the recess 28. In this example, the engaging portion 27 is formed only on the widthwise opening edges 29 of the periphery of the recess 28.

[0036] As shown in Figure 2, the body 11 has a resin-made raised portion 31 that fits inside the protruding contact portion 24 and engages with the engaging portion 27. The raised portion 31 is, for example, a portion that fits into both the recessed portion 25 and the recessed portion 28 on the inner surface of the protruding contact portion 24 and engages with the engaging portion 27 formed on the opening periphery of the recessed portion 28. In this way, the body 11 is fixed to the busbar 10 by the engagement of the engaging portion 27 of the protruding contact portion 24 with the raised portion 31.

[0037] Next, the operation of connector 1 in this embodiment will be described. (Method for molding the engaging portion 27) As shown in Figure 6(a), a busbar 10 is prepared in which the busbar tip portion 18 is bent in a direction substantially perpendicular to the busbar body portion 17. Next, as shown in Figure 6(b), a recess 28 is formed on the back surface of the busbar tip portion 18. The method for forming the recess 28 is preferably, for example, machining. In this example, the recess 28 is formed in two places on the back surface of the busbar tip portion 18.

[0038] As shown in Figure 6(c), after the recess 28 is formed, a protruding contact portion 24 is formed at the busbar tip 18 by press working at the location where the recess 28 is formed. The press working is preferably a method of bending the busbar 10 by pressing a die 33, which corresponds to the shape of the protruding contact portion 24 to be formed, against the recess 28 from the back surface of the busbar 10 with a predetermined pressure. The die 33 is preferably a die with a surface surface that has a circular arc cross-section, specifically a die with a crescent cross-section that is somewhat abruptly indented on both sides.

[0039] In this example, when the bus bar 10 is bent in the mold 33 to form the protruding contact portion 24, the bending deformation of the bus bar 10 forms an engaging portion 27 in the opening of the recess 28. In this way, the engaging portion 27 is formed simultaneously by the press work that forms the protruding contact portion 24. In this manner, multiple bus bars 10 having engaging portions 27 on the inner surface of the protruding contact portion 24 are formed. Then, by insert molding these bus bars 10, a connector body 3 in which multiple bus bars 10 are integrated with resin is manufactured.

[0040] (Floating of the protruding contact portion 24) Figure 7 shows a connector body 3 in which the busbar 10 does not have an engaging portion 27 formed on it. After insert molding, the body 11 shrinks due to cooling. Specifically, after insert molding, as the resin cools, the body 11 shrinks away from the busbar 10. As a result, a gap is created between the busbar 10 and the body 11. When this happens, the contact between the busbar 10 and the mating terminal 13 is unstable when the mating connector 2 is attached to the connector 1, affecting the reliability of current flow.

[0041] (When the busbar 10 is provided with an engaging portion 27) As shown in Figure 8, when an engaging portion 27 is provided on the back surface of the busbar 10, it becomes possible to embed the engaging portion 27 into the body 11 when the connector body 3 is manufactured by insert molding. Therefore, even if the body 11 shrinks in the direction of arrow A in the figure due to cooling after insert molding, the busbar 10 is less likely to lift up because the engaging portion 27 is embedded in the body 11. Thus, it becomes possible to attach the connector 1 and the mating connector 2 in a stable contact state.

[0042] Incidentally, when embedding a portion of the busbar 10 into the body 11, one possible structure is to form a hole in the busbar 10 and embed the periphery of the hole into the body 11. However, in this structure, since a hole is formed in the busbar 10, there is a concern that resin may leak onto the upper surface of the busbar 10 during insert molding. This could lead to contact failure. On the other hand, in this example, it is possible to embed a portion of the busbar 10 into the body 11 without forming a hole in the busbar 10. Therefore, concerns about resin leakage, and consequently, contact failure, can be avoided.

[0043] Furthermore, when embedding a portion of the busbar 10 into the body 11, for example, one could consider a structure in which the end of the busbar 10 is bent by a predetermined amount, and the bent portion is embedded into the body 11. However, in this structure, a portion of the busbar 10 must be used as the bent portion to be embedded into the body 11, and in order to secure the area of ​​the electrical contacts of the busbar 10, the busbar 10 would need to be made larger. As a result, the amount of material used for the busbar 10 increases, which is disadvantageous in terms of cost. On the other hand, in this example, a portion of the back surface of the busbar 10 is embedded into the body 11, so the amount of material used for the busbar 10 does not increase.

[0044] (Effects of the embodiment) According to the configuration of the above embodiment, the following effects can be obtained. (1) The connector 1 comprises a connector body 3 in which a busbar 10, which is electrically connected to a mating terminal 13, is integrally formed with resin by molding. The busbar 10 comprises a protruding contact portion 24 formed by bending a part of the busbar 10 into a protruding shape, and an engaging portion 27 formed on the inner surface of the protruding contact portion 24 so as to be embedded in the body 11 of the connector body 3.

[0045] With this configuration, the busbar 10 can be firmly fixed to the body 11 by embedding the engaging portion 27 on the inner surface of the protruding contact portion 24 into the raised portion 31 of the body 11 that fits inside the protruding contact portion 24. This makes it difficult for the busbar 10 to lift away from the body 11. Furthermore, by providing the engaging portion 27 on the busbar 10 and embedding it in the body 11 as a measure to prevent the busbar 10 from lifting, it is not necessary to form a hole in the busbar 10. Therefore, resin does not creep up onto the upper surface of the busbar 10 during insert molding. Consequently, it is also possible to make it difficult for contact failures to occur in the busbar 10.

[0046] (2) The engaging portion 27 is formed on the bus bar 10 at the same time as the protruding contact portion 24 is formed on the bus bar 10. With this configuration, when the protruding contact portion 24 is formed on the bus bar 10, the protruding contact portion 24 and the engaging portion 27 can be formed at the same time. Therefore, the manufacturing of the bus bar 10 can be simplified.

[0047] (3) The protruding contact portion 24 has a recess 28 on its inner surface, which is formed by thinning the thickness of a part of the bus bar 10. The engaging portion 27 is formed on at least a part of the periphery of the recess 28. With this configuration, when forming the protruding contact portion 24 and the engaging portion 27 on the bus bar 10, it is only necessary to form the recess 28 on the back surface of the bus bar 10 and then bend the part of the bus bar 10 that includes the recess 28. In this respect, it can be said that the manufacturing of the bus bar 10 is simple.

[0048] (4) The recess 28 is formed in a shape having an elongated hole-like opening. The recess 28 is provided with a pair of widthwise opening edges 29 that extend in the width direction of the busbar 10 and are arranged opposite each other, and a pair of width-intersecting opening edges 30 that extend in a direction intersecting the widthwise opening edges 29 and are also arranged opposite each other. The engaging portion 27 is formed on at least the widthwise opening edges 29. With this configuration, the shape of the recess 28 can be made into a simple shape having an elongated hole-like opening. In addition, since the pair of engaging portions 27 are arranged opposite each other, it is possible to create an embedded shape in which the body 11 is sandwiched from both sides by the pair of engaging portions 27. Therefore, the engaging portion 27 can be firmly embedded in the body 11.

[0049] (5) Multiple sets of protruding contact portion 24 and engaging portion 27 are provided on the bus bar 10. With this configuration, the bus bar 10 can be fixed to the body 11 by multiple engaging portions 27, which further contributes to preventing the bus bar 10 from lifting up.

[0050] (6) The protruding contact portion 24 is positioned closer to the tip of the busbar 10. This configuration makes it less likely for the busbar 10 to lift up from its tip, thus further contributing to preventing the busbar 10 from lifting up.

[0051] (7) The busbar 10 has a busbar main body portion 17 which is embedded in the body 11 in at least part of it, and a busbar tip portion 18 which is exposed from the body 11 and is formed in a shape that is bent in a direction intersecting the extending direction of the busbar main body portion 17. The protruding contact portion 24 and the engaging portion 27 are provided on the busbar tip portion 18. With this configuration, the busbar tip portion 18 can be made less likely to lift up from the body 11.

[0052] (8) The body 11 has a seat portion 19 for which the busbar tip portion 18 is placed. The busbar tip portion 18 is formed to have the same width and depth as the seat portion 19 in the portion that is placed on the seat portion 19. With this configuration, if the busbar tip portion 18 is shaped to be placed on the seat portion 19 of the body 11, for example, it may only be able to be formed to have the same area as the seat portion 19. However, since the busbar tip portion 18 is provided with an engaging portion 27, even if there are size limitations on the busbar tip portion 18, the busbar tip portion 18 can be firmly fixed to the seat portion 19.

[0053] (9) The busbar tip 18 is formed in the shape of a rectangular plate. When multiple protruding contact portions 24 are provided, they are arranged in a line along the longitudinal direction of the busbar tip 18. With this configuration, the protruding contact portions 24 can be positioned in a suitable and balanced manner relative to the rectangular plate-shaped busbar tip 18.

[0054] (10) The mating terminal 13 has a plate-shaped portion 14 that contacts the busbar 10. With this configuration, even though the plate-shaped portion 14 of the mating terminal 13 is in contact with the busbar 10, the contact point of the plate-shaped portion 14 is a protruding contact portion 24, so these contacts can be easily made.

[0055] (11) When multiple bus bars 10 are provided, they are arranged in a line in the planar direction of the connector body 3. With this configuration, the shape of the connector body 3 can be made simple, with the bus bars 10 arranged in the planar direction of the connector body 3.

[0056] (Other embodiments) This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0057] As shown in Figure 9, the engaging portion 27 may be formed over the entire width of the back surface of the busbar 10. In this case, it becomes possible to form the engaging portion 27 to be longer, which is more effective in firmly embedding the engaging portion 27 in the body 11.

[0058] The shape of the protruding contact portion 24 is not limited to a semicircular cross-section, but may be changed to other shapes, such as a triangular cross-section or a trapezoidal cross-section. The engaging portion 27 may be formed not in the recess 28, but, for example, on the periphery of the recessed portion 25.

[0059] The busbar tip 18 is not limited to being placed on the seat 19, but may also be placed on a flat surface of the body 11, for example. The shape of the busbar 10 may be a straight, extended plate. In this way, the shape of the busbar 10 may be changed to other shapes as appropriate.

[0060] The shape of the busbar tip 18 is not limited to a rectangular plate shape; for example, it may be circular. Alternatively, the busbar tip 18 may have a shape such as a rectangular plate with a circular disc at its tip.

[0061] • When multiple busbars 10 are provided, the connector body 3 may be shaped such that the busbars 10 are arranged in a line in the height direction within the connector body 3. The busbar 10 may be configured to be provided as only one on the connector body 3.

[0062] The set of the protruding contact portion 24 and the engaging portion 27 is not limited to multiple sets, and may consist of, for example, only one set. The protruding contact portion 24 and the engaging portion 27 are not limited to being formed simultaneously, but may be formed in separate processes.

[0063] The plan view shape of the recess 28 is not limited to an elongated hole shape, and may be changed to other shapes such as a circular shape or a square shape. • The entire periphery of the recess 28 may be formed with an engaging portion 27.
