Electric connector

Abstract

The invention discloses an electric connector, which comprises an insulation substrate, a cover body and an eccentric driving cam, wherein the insulation substrate is provided with a shaft hole, a limiting groove is arranged to surround the shaft hole, two ends of the limiting groove are respectively provided with a first limiting surface; the cover body covers and is arranged on the insulation substrate in a slide way, the cover body is provided with a through hole which is just opposite to the shaft hole, one side of the through hole is provided with a limiting block, and two sides of the limiting block are respectively provided with a second limiting surface; the eccentric driving cam passes through and is arranged in the shaft hole of the insulation substrate and the through hole of the cover body, the eccentric driving cam comprises a driving part and a rotating shaft, the rotating shaft is provided with a stop part, two sides of the stop part are respectively provided with a first stop surface, and two sides of the driving part are respectively provided with a second stop surface; and the eccentric driving cam drives the cover body to slide relative to the insulation substrate under the torque effect, when the cover body slides in place, the first stop surface is stopped on the first limiting surface, and the second stop surface is stopped on the second limiting surface, so the dispersion of the driving force can be realized to realize the double-stop effect.

Description

technical field [0001] The invention relates to the field technology of an electrical connector used to connect a central processing unit and a motherboard, in particular to an electrical connector driven by a cam. Background technique [0002] The electrical connector connecting the central processing unit and the motherboard usually includes an insulating base and a cover. The cover includes several upper receiving grooves, and the insulating base is provided with several lower receiving grooves corresponding to the upper receiving grooves. A socket terminal is provided, and a driving device is provided in the cover body and the insulating base so that the electric connector can be selectively opened or closed. When the electrical connector is in the disconnected state, the pins of the CPU chip module are not in contact with the corresponding socket terminals, and then the driving device is operated to move the cover to one side relative to the insulating base, so that the...

Problems solved by technology

[0004] Although the eccentric driving cam structure of this electrical connector can realize the electrical conduction or disconnection between the central processing unit chip module and the electrical connector, however, the limiting surface of the cover bears all the driving force so that the force is blocked by a single , when the force is too large, the cover is easy to break, which is not conducive to prolonging the service life of the product

[0005] In addition, since the setting direction of the blocking surface is parallel to the moving direction of the cover body, when the eccentric drive cam rotates to open or close, the force direction of the eccentric drive cam is inconsistent with the sliding direction of the cover body, and a large external force is required. Only the torque can make the electrical connector and the CPU chip module smoothly docked, which is not conducive to limiting the torque within the design range
