Low insertion force type socket connector

Abstract

The invention discloses a low-insert force socket connector to connect chip module and print circuit board electrically, which consists of insulating bulk and several conductive terminals in the insulating bulk, wherein the support plane and assembling plane corresponding to support plane are set on the insulating bulk with several terminal containing grooves through support plane and assembling plane; the guide groove is set on and through the terminal containing groove; the conductive terminal is placed in the terminal containing groove, which contains base part, a couple of arm part from two bending extending sides of base part, contact part with smooth arc and level welding part at the bottom of base part; the smooth arc can correct deflection in the inserting course of positive chip module pin.

Description

【Technical field】 [0001] The invention relates to an electrical connector, especially a socket connector with low insertion force mainly used for electrically connecting a chip module and a printed circuit board. 【Background technique】 [0002] Low insertion force socket connectors are widely used in the computer field, and are mainly used to electrically connect two separated electronic components to realize data and signal transmission between them. [0003] The low insertion force socket connector generally includes an insulating body and a number of conductive terminals accommodated in the insulating body. One end of the conductive terminal is provided with a contact portion that can be connected to the pin of the chip module, and the other end is provided with a contact portion that can be electrically connected to the printed circuit board. welded part. When in use, the chip module is pressed so that the pins on it correspond to the contact parts of the conductive ter...

Problems solved by technology

[0005] However, this low insertion force socket connector has at least the following disadvantages: when it is docked with the pins of the chip module, only the elastic arm of the conductive terminal can produce elastic deformation, and the overall elasticity of the conductive terminal is poor; the contact portion of the conductive terminal is curved. In addition, if the pins of the chip module are deflected relative to the normal insertion position during the assembly process, the elastic arm of the conductive terminal is likely to be due to contact with the chip. The pins of the module are interfered and damaged
