Description

Technical Field

[0001] This utility model relates to a terminal structure, and more particularly to a terminal structure that is easier to fix in a mold for subsequent injection molding processes. Background Technology

[0002] Terminals are mainly used for electrical connections, and most of them are housed in a plastic housing to form a connector.

[0003] Most current connectors house multiple terminals within a plastic housing. During the molding process, the multiple terminals are usually first fixed within a mold (existing technology, described in detail here), and then the plastic housing (existing technology, described in detail here) is directly molded onto these terminals using injection molding. This increases the structural strength between the terminals and the plastic housing and prevents moisture penetration.

[0004] like Figure 1 As shown, there is an existing terminal structure A. One end of the terminal structure A is fisheye shaped and is used to insert into a solder hole on a circuit board (existing technology, which will be described in detail here). It is fixed to a circuit board by soldering. The other end is used to electrically connect with another corresponding connector to achieve the effect of electrical connection and to transmit signals or electricity.

[0005] However, when the existing terminal structure A is fixed inside the aforementioned mold, it lacks a positioning design and requires a hard interference method to insert it into the mold. This makes the overall size requirements between the terminal structure and the mold higher, resulting in increased overall mold costs. At the same time, the hard interference process can easily damage the terminal structure.

[0006] Therefore, the problem to be solved by this utility model is how to provide a terminal structure that is easier to fix in a mold for subsequent injection molding processes. Utility Model Content

The connection section connects the first electrical connection terminal and the second electrical connection terminal, and a first positioning interval is provided on the side of the connection section adjacent to the first electrical connection terminal, with corresponding positioning grooves provided on two corresponding sides of the first positioning interval.

[0038] To further understand the techniques, means, and effects adopted by this utility model to achieve the predetermined objectives, preferred and feasible embodiments are described below in detail with reference to the figures:

[0039] like Figures 2 to 5 As shown in the figure, this utility model provides a terminal structure 10 for fixing in the aforementioned mold and for injection molding the aforementioned plastic shell.

[0040] The terminal structure 10 includes a first electrical connection terminal 11, a second electrical connection terminal 12, and a connection section 13. The first electrical connection terminal 11 has a fisheye shape (commonly known as a fisheye terminal). The second electrical connection terminal 12 is a long column shape. The connection section 13 connects the first electrical connection terminal 11 and the second electrical connection terminal 12, and the connection section 13 has a bending section 131 and two positioning sections connecting the bending section 131, the first electrical connection terminal 11, and the second electrical connection terminal 12.

[0041] In this embodiment, the positioning interval connecting the first electrical connection end 11 and the bending interval 131 is the first positioning interval 132, and the positioning interval connecting the second electrical connection end 12 and the bending interval 13 is the second positioning interval 133. Corresponding positioning grooves 14 are provided on two corresponding sides of the first positioning interval 14. Each positioning groove 14 is generally V-shaped and recessed from the side of the first positioning interval 132 toward the center; and the width of the connecting section 13 is slightly larger than the width of the first electrical connection end 11.

[0042] The two sides of the connection between the second positioning section 133 and the second electrical connection end 12 are respectively formed with corresponding inclined surfaces 15, so that the width of the connection section 13 is greater than the width of the second electrical connection end 12.

[0043] However, in this embodiment, although the bending section 131 is provided in the connection section 13, in actual application, the bending section 131 may not need to be bent, so that the overall terminal structure is formed into a long strip.

[0044] Please also refer to Figures 2 to 5 When the terminal structure 10 of this utility model is to be fixed inside the aforementioned mold, a spring piece 20 can be respectively provided on both sides of the first positioning interval 132, so that each spring piece 20 can be locked in each positioning groove 14. Then, a positioning rod 30 is respectively used on the outside of each spring piece 20 to limit the displacement of the spring piece 20. At the same time, the second electrical connection part 12 is fixed, so that the terminal structure 10 can obtain support in two directions in the mold, thereby enabling the terminal structure 10 to be more effectively fixed in the mold, so as to facilitate the injection molding process of the aforementioned plastic shell in the mold.

[0045] like Figure 6 As shown, another terminal structure 10' in this invention is presented. In this embodiment, the positioning groove 14 is mainly disposed on both sides of the second positioning area 133. Therefore, the terminal structure 10' can be more stably fixed in the mold by fixing the positioning groove 14 and the first positioning area 132 in the aforementioned mold respectively.

[0046] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
