Electric connector

Abstract

The invention discloses an electric connector. The electric connector is used for electrically connecting a chip module, and the chip module is provided with a plurality of contact pads. The electricconnector comprises an insulating body and a plurality of terminals, wherein a plurality of accommodating grooves are formed in the insulating body; the terminals are accommodated in the accommodatinggrooves respectively, each terminal is provided with a main body part, an extension arm and at least one abutting part, each main body part is positioned in the corresponding accommodating groove, each extension arm is connected to one end of the corresponding main body part, the extension arms exceed the upper surface of the insulating body upwards and are used for electrically connecting the contact pads, the at least one abutting part is connected to one end of the corresponding main body part, the abutting parts exceed the upper surface of the insulating body upwards, and the abutting parts are used for abutting against the chip module and is not in contact with or in a non-electric contact with the contact pads. According to the electric connector disclosed by the invention, each abutting part is arranged at one end of the corresponding main body part, when the chip module is pressed and connected to the extension arms to a certain degree downwards, the chip module abuts againstthe abutting parts, the chip module is blocked by the abutting parts, and the chip module is prevented from being pressed and connected downwards excessively to cause that the terminals are damaged.

[0002] An existing electrical connector is used to electrically connect the chip module to the circuit board, and realize the electrical connection with the chip module by pressing, and the chip module is provided with a contact with the electrical connector. Pad, the electrical connector generally includes an insulating body and a plurality of conductive terminals accommodated in the insulating body, the conductive terminals are provided with elastic arms, and the elastic arms are provided with contacts electrically connected to the contact pads of the chip module. The contact part, the conductive terminal has good elasticity, and an external pressure needs to be applied to the conductive terminal through other components, so that the conductive terminal is elastically deformed and pressed against the contact pad of the chip module by its elastic force Contact, so as to achieve the electrical connection between the conductive terminal and the contact pad of the chip module, the other end of the conductive terminal far away from the chip module is electrically connected to the circuit board, so as to realize the electrical connection between the chip module and the circuit board However, when the chip module crimps the elastic arm, it is possible to over-crimp the elastic arm so that the conductive terminal is damaged

[0003] At present, in order to prevent the overvoltage terminals of the chip module on the market, a boss is provided on the surface of the insulating body. When the chip module is crimped to the conductive terminal to a certain extent, the chip module will touch the boss. The boss prevents further crimping of the chip module to avoid damage to the conductive terminals due to overvoltage. However, with the continuous development of electronic technology, the size and height of electrical connectors are getting smaller and smaller, and the arrangement of terminals The density is required to be denser and denser. In this case, the space for setting the boss on the insulating body is getting smaller and smaller, and the difficulty is getting bigger and bigger.
