Description

Vehicle-mounted connector terminal

Technical Field

The utility model belongs to the technical field of electric connectors, and particularly relates to a vehicle-mounted connector terminal.

Background

With the increasing demands of people on safety, environmental protection, comfort, intelligence and the like of automobiles, the application of automobile electronic products is increasing, which causes the number of applications of the vehicle-mounted connectors to be increased.

There are two general ways of fixing the external housing (divided into a front housing and a rear housing) and the internal insulator in the vehicle connector in the prior art: 1. the front end shell and the tail end shell are matched with each other, then the insulator is clamped between the front end shell and the tail end shell, and then the front end shell and the tail end shell are fixed together in a laser welding mode, or the front end shell and the tail end shell are fixed by spot-mortise work, and finally the front end shell and the tail end shell are reinforced together in a laser welding mode; 2. the outer shell is directly made into an integrated structure, and an elastic material is adopted for integrated stamping and forming, so that the insulator is pressed into the integrated structure.

The first fixing mode is multiple in assembly procedures, complex in operation and high in cost, and can not detect mortise and tenon conditions, welding effects and welding leakage conditions of each product during mass production, so that the product has higher quality risk. The outer shell in the second fixing mode is generally directly formed by integrally stamping an elastic material, and the elastic material is generally expensive, so that the input cost is high. As disclosed in patent CN114069299a, a plug terminal structure of a vehicle-mounted communication connector is disclosed, a female terminal is coaxially installed in a shielding tube, an inner plastic shell is installed between the female terminal and the shielding tube, an annular groove is formed in the middle of the outer surface of the inner plastic shell, the female terminal is integrally and continuously formed by a front section, a middle section and a tail section, the front section is of a symmetrical two-piece spring arm structure, and an outward-opening horn mouth structure is formed at the front end of the front section through punching and rounding; the middle section is of a cylindrical structure, convex fins are symmetrically arranged on two sides of the middle section, and the tail part is of a radial line pressing structure. Although the utility model has simple structure and reliable hanging, and the improved structure of the inner plastic shell meets the requirements of the injection molding process and the impedance characteristic of the product, the second fixing mode is adopted between the outer shielding tube and the female terminal, so the input cost is higher.

Therefore, how to design a vehicle-mounted connector terminal with simple structure, convenient assembly, high product quality and low input cost is a technical problem to be solved by those skilled in the art.
