Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of connecting terminal, especially a metal connector terminal implantation injection molding product structure. BACKGROUND

[0002] In the manufacturing process of plastic parts, when embedding thin metal inserts (such as connector contact terminals), the problem of positional deviation and perpendicularity deviation often arises.

[0003] Although the mold precision can ensure the perpendicularity and positional accuracy of the metal implantation, after the product is demolded, the thin metal part often deviates, resulting in that even if the root position is correct, the head will exceed the design tolerance. Trying to set a reverse pre-deflection on the mold to compensate for this problem will cause scratching of the metal insert and the mold, damaging the surface plating. SUMMARY

[0004] In view of the above problems existing in the existing metal inserts, the present application aims to provide a metal connector terminal implantation injection molding product structure which is not easy to deform and has high stability.

[0005] The specific technical solutions are as follows:

[0006] A metal connector terminal implantation injection molding product structure, comprising a metal insert, one end of the metal insert is injection molded with a plastic part, and both sides of the other end of the metal insert are provided with openings.

[0007] As a further improvement and optimization of the present scheme, the opening is a rectangular long slot.

[0008] As a further improvement and optimization of the present scheme, the metal insert is a rectangular structure, and the two openings are located on two sides of the metal insert.

[0009] As a further improvement and optimization of the present scheme, the width of the opening is one-third of the width of the metal insert.

[0010] As a further improvement and optimization of the present scheme, the length of the opening is greater than five times the thickness of the metal insert.

[0011] As a further improvement and optimization of the present scheme, the top of the plastic part is provided with a first inclined surface on both sides, the inner wall of the bottom of the two openings is provided with a second inclined surface, and the two first inclined surfaces and the two second inclined surfaces are in an "eight" shape.

[0012] As further improvement and optimization of the scheme, the connecting part is made of plastic material, the metal inserts are provided with a plurality of metal inserts, one end of the metal inserts is connected to the connecting part, and the plastic part is formed between one end of each metal insert and the connecting part.

[0013] As further improvement and optimization of the scheme, the metal inserts are arranged at equal intervals along the length direction of the connecting part.

[0014] The above technical scheme has the following positive effects compared with the prior art:

[0015] The utility model discloses a plastic part is formed by embedding the metal insert in the mold cavity, and the metal insert is clamped by the mold when the metal insert is inserted into the mold cavity, so that the stress generated by the plastic part on the metal insert can be reduced, and the inclination of the metal insert caused by the stress release after the mold is opened can be avoided.
