Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically to a terminal fixing structure. Background Technology

[0002] Currently, for this type of product, due to the lack of support within the mold cavity during injection molding, the pins are prone to uneven height. If an inner mold is added to fix the terminal, two injection molding processes are required, which increases investment and may also create new problems and uncontrollable factors. Therefore, there is an urgent need for a terminal fixing structure to solve the above-mentioned problems. Utility Model Content

[0003] The purpose of this utility model is to provide a terminal fixing structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a terminal fixing structure, including a support device, wherein the inner end face of the support device is provided with two sets of guide bushings.

[0005] The second bending terminal group is fixedly snapped onto the upper part of the inner end face of the support device, and the first bending terminal group is provided at the lower part of the inner end face of the support device.

[0006] A fixed terminal insert is fixedly snapped onto the inner end face of the support device, and the fixed terminal insert is used to support and limit the first bent terminal group and the second bent terminal group.

[0007] Preferably, the fixed terminal insert includes an insert housing, the upper end face of which is provided with a mold cavity support portion, and the lower end face of which is provided with a terminal contact portion.

[0008] Preferably, the support device includes a housing, two sets of bushing blocks are provided at the rear of the side end face of the housing, and terminal limiting blocks are provided at the upper and lower parts of the inner end face of the housing. Three sets of terminal slots are equally spaced on the inner end faces of the two sets of terminal limiting blocks.

[0009] Preferably, the bushing is fixedly engaged with the bushing clip, which can effectively improve the stability of subsequent locking and limiting of the bushing.

[0010] Preferably, both the first bent terminal group and the second bent terminal group are fixedly engaged with the inner end face of the terminal limiting block through the terminal slot. The terminal slot can provide sufficient limiting foundation for the first bent terminal group and the second bent terminal group, thereby improving the accuracy and stability of the subsequent positioning of the first bent terminal group and the second bent terminal group inside the support device.

[0011] Preferably, the upper part of the insert housing is supported and fitted to the outer shell through the mold cavity support, and the first bent terminal group and the second bent terminal group are supported and fitted to the lower part of the insert housing through the terminal contact portion. The upper part of the insert housing can be supported and limited by the mold cavity support portion and the interior of the outer shell, thereby improving the stability of the subsequent terminal contact portion supporting the first bent terminal group and the second bent terminal group.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The structural component in this utility model is equivalent to an insert for injection molding. After the terminal is inserted into the mold, it is installed. The limiting structure can be added according to the actual state of the mold. After adding the fixed terminal insert, the position of the first bending terminal group and the second bending terminal group can be effectively corrected. Compared with the existing technical solution, there is no need to open a new inner mold. Each product can be formed in one injection molding, which improves production efficiency and reduces costs.

[0014] 2. This utility model ensures terminal consistency and improves yield; one-time molding improves production efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 One embodiment of this utility model provides a terminal fixing structure, including a support device 5, wherein the inner end face of the support device 5 is provided with two sets of guide bushings 4.

Terminal limiting blocks 51 are provided at the upper and lower parts of the inner end face of the housing 53. Three sets of terminal slots 52 are equally spaced on the inner end face of the two sets of terminal limiting blocks 51.

[0026] The bushing 4 is fixedly engaged with the bushing clip 54, which can effectively improve the stability of subsequent locking and limiting of the bushing 4.

[0027] The first bent terminal group 1 and the second bent terminal group 2 are both fixedly engaged with the inner end face of the terminal limiting block 51 through the terminal slot 52. The terminal slot 52 can provide sufficient limiting base for the first bent terminal group 1 and the second bent terminal group 2, thereby improving the accuracy and stability of the subsequent positioning of the first bent terminal group 1 and the second bent terminal group 2 inside the support device 5.
