Technical Field

The invention belongs to the technical field of electrical appliance connecting equipment, and particularly relates to an electric connector.

Background

When the operating power of the equipment is high, high current is often needed, and the electric connector used for high current conduction often has poor contact during connection due to processing errors or overlong use time and the like, so that the equipment cannot work normally, and even has potential safety hazards.

Disclosure of Invention

The invention aims to provide an electric connector, aiming at solving the technical problem that the electric connector in the prior art is easy to have poor contact during connection.

The present invention is achieved as such, an electrical connector comprising:

the electric connection socket at least comprises a conductive socket capable of conducting electricity and an abutting spring capable of conducting electricity, wherein the conductive socket is provided with a plug-in slot, and the abutting spring is attached to the side wall of the plug-in slot;

the electric connection contact pin at least comprises a contact pin which can conduct electricity, extends outwards and can be matched and plugged with the plugging groove;

the contact pin is inserted into the insertion groove, the contact spring is radially contracted after the contact pin is inserted into the insertion groove, and two radially opposite sides of the contact spring are respectively abutted against the outer wall of the contact pin and the groove side wall of the insertion groove.

Compared with the prior art, the invention has the technical effects that: according to the invention, the conductive abutting springs are arranged in the inserting groove, when the contact pins are inserted into the inserting groove, two opposite sides of the abutting springs are respectively abutted against the outer wall of the contact pins and the groove side wall of the inserting groove, and the contact springs are radially contracted to become thin due to the radial acting force of the contact pins, so that the number of turns is increased, the contact area between the contact springs and the contact pins is increased, the electric connection effect is enhanced, and the integral shape of the conductive seat and the groove depth of the inserting groove are not influenced. In addition, when the abutting spring is damaged, the abutting spring only needs to be removed and replaced, and the conductive seat does not need to be replaced. Secondly, the machining error at the contact pin is great, when the footpath is long thin excessively, can realize the electricity of the two through changing thicker conflict spring and connect, and the suitability is strong for contact pin and conductive seat zonulae occludens prevent not hard up, avoid appearing the condition of contact failure, eliminate the potential safety hazard.
