DETAILED DESCRIPTION

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0021] The embodiment of the present application provides a frame connector to solve the problems in the prior art that the frame connector has many processes, low production efficiency, and the injection molding process can only be carried out after the support terminal is cut into material strips, which makes the terminal easily deformed, resulting in poor size and other quality problems.

[0022] Reference Figure 1-Figure 2 A frame connector includes: an integrated frame body 10, an electrical connection device 30, a support terminal 20 and a movable terminal 40. The integrated frame body 10 includes a flat plate portion 100 and a groove portion 110. The support terminal 20 is provided with a plurality of and is installed in the groove portion 110 of the frame body 10. The electrical connection device 30 is fixedly connected to a connection hole 120 on an end surface of the frame body 10 close to the groove portion 110 and is electrically connected to the support terminal 20. The movable terminal 40 is installed on the surface of the flat plate portion 100 of the frame body 10. A plurality of discontinuous opening structures 130 are provided on the surface of the groove portion 110 of the frame body 10, and part of the structure of the support terminal 20 is exposed from the opening structure 130.

[0023] It should be noted that, from a process point of view, the process steps of the integral frame connector are divided into two steps. The first step is to inject and mold the support terminal 20 and the electrical connection device 30 connected as a whole by the connecting bridge 2134 with the frame body 10 at one time, and the second step is to assemble the movable terminal 40 with the frame body 10 directly injected in the first step. Here, by designing the frame body 10 of the frame connector into an integrated structure, the process steps of assembling the HSG base part and the frame body 10 and then injecting and molding are reduced, the production process is optimized, the efficiency is improved, and the product cost is reduced.

[0024] In addition, since in the first step, the multiple support terminals 20 are connected together by the connecting bridge 2134 to form an integral structure, the terminal shape can be kept stable during injection molding without bending. The role of the reserved opening structure 130 is to cut off the connection parts of the support terminals 20 in the frame body 10 after the injection molding is completed. This can reduce the process steps, ensure that the support terminals 20 are not deformed, and realize the functional role of the support terminals 20.

[0025] Specifically, refer to Figure 3 The support terminal 20 is generally in the shape of a long strip, and includes a first side support terminal 201 and a second side support terminal 202 symmetrically arranged on both sides of the groove portion 110 of the frame body 10, and a first middle support terminal 203 and a second middle support terminal 204 located between the two; the first side support terminal 201 and the first middle support terminal 203 are connected by at least one connecting bridge 2134, the first middle support terminal 203 and the second middle support terminal 204 are connected by at least one connecting bridge 2134, and the second middle support terminal 204 and the second side support terminal 202 are connected by at least one connecting bridge 2134. In this embodiment, three connecting bridges 2134 are arranged between each support terminal 20, and the connecting bridges 2134 and the extending direction of the support terminal 20 are perpendicular to each other. Multiple support terminals 20 are connected and fixed by the above-mentioned connecting bridges 2134. After the first step of injection molding, the connecting bridges 2134 between all the support terminals 20 and part of the first intermediate support terminals 203 and part of the second intermediate support terminals 204 are exposed from the opening structure 130, and the connecting bridges 2134 between the support terminals 20 can be cut through the opening structure 130.

In this embodiment, three connecting bridges 2134 are provided between each supporting terminal 20, and correspondingly, the opening structures 130 are provided in a square form and provided in three forms. After the supporting terminals 20, the electrical connecting device 30 and the frame body 10 with the opening structures 130 are integrally injection molded, all the connecting bridges 2134 are cut off through the opening structures 130.

[0027] Reference Figure 2 A plurality of mounting holes are provided on the flat plate portion 100 on one side of the frame body 10 away from the hole structure 130, and the mounting holes include a first mounting hole 101 arranged near the edge of the groove portion, second mounting holes 102 arranged at both ends of the flat plate portion 100 in the width direction, a plurality of third mounting holes 103 arranged on one side in the length direction of the flat plate portion 100, and a special-shaped fourth mounting groove 104 arranged on the upper surface of the flat plate portion.

[0028] Corresponding to the mounting holes, the movable terminal 40 includes a first terminal 401, multiple second terminals 402, multiple third terminals 403 and multiple fourth terminals 404.

[0029] In another feasible embodiment, in order to ensure the sealing and stability of the supporting terminal 20 in the frame body 10, a separate cover 50 may be provided, and the cover 50 is used to cover all the opening structures 130. The cover 50 here may be provided as a patch or film of an insulating material (refer to Figure 5 ), or after the support terminal 20, the electrical connection device 30 and the frame body 10 are injection molded, and the connecting bridge 2134 is cut off, the cover 50 is again integrally injection molded with the frame body 10 in the above step, and the integrally injection molded finished frame connector is as follows Figure 4 shown.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
