[0006] Problems to be solved by utility models

[0007] When a resin-based covering member is used to cover a terminal, for example during insertion molding, the resin used for covering sometimes seeps into the inner portion of the bent part of the terminal, creating burrs in that area. This necessitates labor-intensive deburring. This specification provides a technique that reduces the labor required to deburr the bent portion of the terminal.

[0008] Solution for solving the problem

[0009] In a first embodiment of this technology, the terminal structure includes a terminal and a resin covering member that partially covers the terminal. The terminal includes: a first plate-shaped portion extending along a first direction; a second plate-shaped portion extending along a second direction different from the first direction; and a curved portion connecting the first portion and the second portion. The covering member completely covers the outer and inner surfaces of the curved portion.

[0010] In structures where the inner surface of the bent portion of the terminal is not covered by a covering member, fine burrs sometimes form on the inner side of the bent portion during insertion molding. In contrast, according to the structure described above, since the inner surface of the bent portion of the terminal is actively covered by the covering member, the formation of fine burrs on the inner side of the bent portion can be suppressed. This reduces the labor required for deburring at the bent portion of the terminal. Furthermore, during insertion molding, die alignment at the bent portion of the terminal becomes easier.

[0011] In the second technical solution, according to the first technical solution described above, the second portion of the terminal may have a protrusion that protrudes laterally. Alternatively, the covering member may cover the curved portion and the curved end of the protrusion.

[0012] This structure can suppress the formation of fine burrs at the curved end of the protrusion. This reduces the labor required for deburring.

[0013] In the third technical solution, it is also possible that, according to the first or second technical solution described above, the covering member covers the outer surface of the first part of the terminal, but does not cover the inner surface of the first part.

[0014] In structures where the inner surface of the first part of the terminal is not covered, the resin used for covering can easily enter the inner part of the bent portion of the terminal during insertion molding. However, by actively covering the inner surface of the bent portion of the terminal with the covering member, it is possible to suppress the generation of fine burrs on the inner part of the bent portion.

[0015] In the fourth technical solution, it is also possible that, according to any of the first to third technical solutions described above, the contact area between the resin covering the outer surface of the bent portion of the terminal and the terminal is larger than the contact area between the resin covering the inner surface of the bent portion and the terminal.

[0016] This structure can adequately protect the outer surface of the bent portion of the terminal. On the other hand, it can prevent excessive protection of the inner surface of the bent portion of the terminal. Attached Figure Description

Detailed Implementation

[0022] The terminal structure 2 of the embodiment will be described with reference to the accompanying drawings. Figures 1 to 3As shown, the terminal structure 2 of this embodiment includes a metal terminal 4 and a resin covering member 6 that partially covers the terminal 4. The terminal structure 2 is used, for example, in electrical products.

[0023] Terminal 4 is manufactured by bending a plate-like member made of metal (e.g., copper) and is conductive. Terminal 4 includes: a plate-shaped first portion 10; a plate-shaped second portion 12 extending in a direction different from the first portion 10; and a bent portion 14 connecting the first portion 10 and the second portion 12. The first portion 10 of terminal 4 extends in a first direction, and the second portion 12 of terminal 4 extends in a second direction different from the first direction. The first direction and the second direction are, for example, orthogonal. The angle between the first direction and the second direction is not particularly limited.

[0024] The curved portion 14 is located between the first portion 10 and the second portion 12. The curved portion 14 bends from the first direction to the second direction. The curved portion 14 bends by, for example, 90°. The angle formed by the curved portion 14 is not particularly limited. The curved portion 14 has an outer surface 20 facing outward and an inner surface 22 facing inward.

[0025] The second portion 12 of terminal 4 has a pair of protrusions 16 that project laterally. Therefore, the lateral width of the second portion 12 of terminal 4 is wider than the lateral width of the first portion 10 of terminal 4. The pair of protrusions 16 project in a direction along the surface of the second portion 12. Each protrusion 16 has a first side surface 61, a second side surface 62, and a third side surface 63. The first side surface 61 is the side surface on the side of the curved portion 14 in the protrusion 16. The second side surface 62 is the side surface on the side of the protrusion in the protruding direction in the protrusion 16. The third side surface 63 is the side surface of the protrusion 16 opposite to the first side surface 61 (opposite to the curved portion 14).

[0026] The cover member 6 is integral with the terminal 4, for example, by using resin embedding molding. The cover member 6 is insulating. The cover member 6 has a first cover portion 40 that covers the first portion 10 of the terminal 4 and a bent cover portion 42 that covers the bent portion 14 of the terminal 4. The first cover portion 40 covers the outer surface 102 of the first portion 10 of the terminal 4. The inner surface 104 of the first portion 10 of the terminal 4 is not covered by the cover member 6 and is exposed from the cover member 6.

[0027] The curved cover portion 42 completely covers the curved portion 14 of the terminal 4. The curved cover portion 42 completely covers the outer surface 20 and inner surface 22 of the curved portion 14 of the terminal 4. The curved cover portion 42 covers from one end of the curved portion 14 of the terminal 4 to the other end in a direction along the surface of the terminal 4.

[0028] The curved cover portion 42 includes an outer surface portion 50 that covers the outer surface 20 of the curved portion 14 of the terminal 4 and an inner surface portion 52 that covers the inner surface 22 of the curved portion 14 of the terminal 4. The amount of resin on the outer surface portion 50 of the curved cover portion 42 is greater than the amount of resin on the inner surface portion 52. The contact area between the outer surface portion 50 of the curved cover portion 42 and the terminal 4 is larger than the contact area between the inner surface portion 52 and the terminal 4.

[0029] Furthermore, the covering member 6 includes a protruding covering portion 44 that covers the end of the protrusion 16 of the second portion 12 of the terminal 4. The protruding covering portion 44 is integrally formed with the curved covering portion 42. The protruding covering portion 44 covers the first side 61 of the protrusion 16 of the terminal 4. In addition, the protruding covering portion 44 may also cover a portion of the second side 62 of the protrusion 16 of the terminal 4 (the portion closer to the first side 61). On the other hand, the protruding covering portion 44 does not cover the third side 63 of the protrusion 16 of the terminal 4.

[0030] (Effect)

[0031] The terminal structure 2 of the embodiment has been described above. As can be seen from the above description, the terminal structure 2 includes a terminal 4 and a resin covering member 6 that covers the terminal 4. The covering member 6 completely covers the outer surface 20 and inner surface 22 of the curved portion 14 of the terminal 4.

[0032] In structures where the inner surface 22 of the bent portion 14 of the terminal 4 is not covered by the covering member 6, fine burrs sometimes form on the inner side of the bent portion 14 during insertion molding. In contrast, according to the above structure, since the inner surface 22 of the bent portion 14 of the terminal 4 is actively covered by the covering member 6, the formation of fine burrs on the inner side of the bent portion 14 can be suppressed. This reduces the labor required for deburring the bent portion 14 of the terminal 4. Furthermore, during insertion molding, alignment of the mold at the bent portion 14 of the terminal 4 becomes easier.

[0033] Furthermore, the covering member 6 covers the bent portion 14 of the terminal 4 and also covers the end of the protrusion 16 of the terminal 4 on the bent portion 14 side. With this structure, the generation of fine burrs at the end of the protrusion 16 of the terminal 4 on the bent portion 14 side can be suppressed. This reduces the labor required for deburring.

[0034] Furthermore, the covering member 6 covers the outer surface 102 of the first portion 10 of the terminal 4, but does not cover the inner surface 104 of the first portion 10. In the structure where the inner surface 104 of the first portion 10 of the terminal 4 is not covered, the resin used for covering can easily accidentally enter the inner portion of the bent portion 14 of the terminal 4 during insertion molding. However, since the inner surface 22 of the bent portion 14 of the terminal 4 is actively covered by the covering member 6, it is possible to suppress the generation of fine burrs on the inner portion of the bent portion 14.

[0035] The contact area between the resin covering the outer surface 20 of the bent portion 14 of the terminal 4 and the terminal 4 is larger than the contact area between the resin covering the inner surface 22 of the bent portion 14 and the terminal 4. This structure helps to suppress deformation of the terminal 4.

[0036] The above description details specific examples of this utility model, but these are merely illustrative and do not limit the scope of the claims. The technology described in the claims includes various modifications and variations of the above-described specific examples. The technical elements described in this specification or drawings are technically useful individually or in various combinations, and are not limited to the combinations described in the claims at the time of application. Furthermore, the technology illustrated in this specification or drawings can achieve multiple objectives simultaneously, and achieving even one of these objectives is itself technically useful.
