Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to a high-reliability housing riveting pin adhesive head assembly. Background Technology

[0002] In modern industrial manufacturing, especially in the electronics industry, the housing structure, as a key component that supports and protects internal parts, directly affects the overall performance and lifespan of the equipment due to its connection reliability. Riveting and snap-fit ​​connections, as a commonly used housing connection method, offer advantages such as ease of operation and high connection strength, and are widely used in the assembly process of various products.

[0003] Because the locking pin and the housing are made of different materials, traditional riveting techniques for the locking pin can accelerate potential corrosion under extreme environments, reducing its service life. Furthermore, the wall thickness at the locking pin riveting location and the size of the locking pin riveting hole can affect the locking pin's fit; if the dimensions are out of tolerance, the locking pin is prone to incomplete riveting and loosening. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a highly reliable housing riveting pin adhesive head assembly, which can effectively solve the problems in the existing technology.

[0006] Technical solution

[0007] This utility model provides a highly reliable housing riveting pin adhesive head assembly, including a housing, a groove is provided on one side of the housing, and a pin is fixed in the groove by adhesive.

[0008] Furthermore, the locking pin has a T-shaped structure, and the top of the locking pin is a trumpet shape with a larger outer side and a smaller inner side.

[0009] Furthermore, the trough has a T-shaped structure, and an annular groove is provided on the inner side of the trough.

[0010] Furthermore, the adhesive is an epoxy adhesive structure.

[0011] Beneficial effects

[0012] This invention uses adhesive to fix the locking pin and the housing together. The adhesive, specifically epoxy glue, has high bonding strength after curing, meeting the impact resistance requirements after the locking pin is riveted. Filling the gap between the locking pin and the housing with glue isolates the connection between them, reducing corrosion caused by potential differences. The glue, combined with the loosening riveting process, significantly reduces the types of locking pins used, lowering inventory pressure. Furthermore, the glue fills the gaps in the housing, increasing the connector's protection level.

[0013] In this device, epoxy adhesive with high bonding strength and resistance to complex environments after curing is added between the housing and the locking pin. The adhesive is filled and cured in a vacuum oven. The traditional tight-riveting locking pin process is changed to loose riveting, leaving a gap for the adhesive to fill and increasing the amount of adhesive. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example: A high-reliability housing riveting pin adhesive head assembly, see attached drawing. Figure 1 -Appendix Figure 4The connector includes a housing 1, with a groove 11 on one side. A locking pin 2 is fixed within the groove 11 using adhesive 3. The locking pin 2 and the housing 1 are fixedly connected using adhesive 3. After curing, the adhesive 3 (epoxy glue) has high bonding strength, meeting the impact resistance requirements after the locking pin 2 is riveted. The glue filling between the locking pin 2 and the housing isolates the connection between them, reducing corrosion caused by potential differences. The glue, combined with the loosening riveting process, significantly reduces the types of locking pins 2, lowering inventory pressure. Furthermore, the glue fills the gaps in the housing, increasing the connector's protection level.

[0023] The locking pin 2 has a T-shaped structure, and the top of the locking pin 2 is a trumpet shape with a larger outer side and a smaller inner side; the groove 11 has a T-shaped structure, and the inner side of the groove 11 has an annular groove; the adhesive 3 is an epoxy adhesive; in this device, epoxy adhesive with high bonding strength and resistance to complex environments after curing is added between the shell and the locking pin 2, and the adhesive is filled and cured in a vacuum oven, and the traditional tight riveting process of the locking pin 2 is changed to loose riveting, leaving a gap for the adhesive filling and increasing the amount of adhesive filling.
