Electric connector

Abstract

The invention discloses an electric connector which is used for electrically connecting a chip module to a printed circuit board and comprises an insulating body and conductive terminals, wherein the conductive terminals are contained in the insulating body, and the insulating body is provided with containing slots, first interference parts and second interference parts, wherein each first interference part and each second interference part are positioned at the two opposite sides of each containing slot, each second interference part is higher than each first interference part on the vertical direction, and the conductive terminals are contained in the containing slots and are in interference fit with the first interference parts and the second interference parts; in the process of assembling the conductive terminals onto the insulating body, the conductive terminals are firstly in interference fit with the second interference parts, so that the conductive terminals incline towards the direction of the first interference parts, the distance between the contact parts of the conductive terminals is smaller than the distance between welding parts, and the development trend that the distance between the conductive sheets of the chip module is decreased day by day can be satisfied.

Description

【Technical field】 [0001] The invention relates to an electrical connector, in particular to an electrical connector electrically connecting a chip module to a printed circuit board. 【Background technique】 [0002] An electrical connector related to the present invention is used to electrically connect a chip module to a printed circuit board, comprising an insulating body and a plurality of conductive terminals accommodated in the insulating body. The insulating body is roughly in the shape of a cuboid, including an upper surface for receiving the chip module and a lower surface for mounting on the printed circuit board. The upper surface is provided with a plurality of receiving grooves penetrating to the lower surface. The conductive terminal is accommodated in the receiving groove, which includes a holding part positioned in the receiving groove, an elastic part extending upward from the holding part, and a welding part extending downward from the holding part. The end ...

AI Technical Summary

Problems solved by technology

[0003] With the development of science and technology, the chip module is developing towards miniaturization and densification, which leads to the reduction of the distance between the conductive sheets on the chip module. However, due to the limitation of the manufacturing process, the printed circuit board cannot be further reduced. The distance between the conductive sheets

At present, the industry usually overcomes this problem by setting an adapter board. However, this method not only increases the cost, but also increases the height of the electrical connector, which is not conducive to the development trend of miniaturization of the electrical connector.
