Description
Technical Field
The invention belongs to the field of automobile accessories, and particularly relates to a plug terminal structure of a vehicle-mounted communication connector.
Background
The head of the female terminal of the existing vehicle-mounted communication connector is in a closing-up design, and the inner ring is chamfered, so that high requirements on the position degree and the concentricity of the male terminal and the female terminal are met. The front stop design of the middle and rear parts has higher closing difficulty at two sides. And in the process of signal transmission of the vehicle-mounted communication connector, shielding parts are needed around the terminals.
Disclosure of Invention
The invention aims to overcome the defects and provide the fixing and locking structure of the automobile connector, which has the advantages of simple structure, convenience in assembly, higher strength, reliability and durability.
In order to achieve the purpose, the invention adopts the technical scheme that:
the utility model provides a vehicle-mounted communication connector plug terminal structure which characterized in that: the female terminal is coaxially arranged in the shielding pipe, an inner plastic shell is arranged between the female terminal and the shielding pipe, an annular groove is formed in the middle of the outer surface of the inner plastic shell, and the air in the annular groove is used for compensating the impedance characteristic value in the gap.
The female terminal is integrally and continuously formed by a front section, a middle section and a tail part, the front section is of a symmetrical two-piece elastic arm structure, and an outward-opening horn mouth structure is manufactured at the front end of the front section through punching and rounding; the middle section is a cylindrical structure, convex fins are symmetrically arranged on two sides of the middle section, and the tail of the middle section is made into a line pressing structure with one side open in the radial direction.
Furthermore, two sides of the rear end of the middle section are symmetrically provided with outward-turning bosses which are used as forward stop structures.
And moreover, concave compression ribs are arranged in the wire pressing structure at the tail part at intervals in the axial direction and are used for increasing the wire releasing strength.
And, the female terminal passes through the fin and moulds the shell cooperation with the interior.
The invention has the beneficial effects that:
1. the invention has simple structure and is formed by the traditional process, thereby having cost advantage.
2. The hanging connection is reliable, and the terminal falling-off standard can be met.
3. The horn mouth design can effectively guarantee the cooperation of the male terminal and the female terminal, and the conditions of PIN needle deflection, terminal ejection and the like are avoided.
4. The improved structure of the inner plastic shell achieves the specified impedance characteristic value increasing and compensating structure through metal, plastic and air, and not only meets the requirements of injection molding process, but also meets the requirements of product impedance characteristic.
