Problems solved by technology

[0003] When the conductive terminal is assembled into the terminal receiving groove from bottom to top, because the width of the middle part is larger than the distance between the protrusions, the middle part will spread the two protrusions, and because the protrusion is close to the bottom surface of the body, the contact beam will be affected. The force arm is short, the stress is concentrated, and it is easy to cause fatigue of the contact beam

Embodiment Construction

[0031] In order to facilitate a better understanding of the purpose, structure, features, and effects of the present invention, the present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as Figure 1 to Figure 5 Shown is the first embodiment of the electrical connector 100 of the present invention, which is used to electrically connect a chip module A to a circuit board B (ie, a substrate), which includes a body 1 and is assembled on the bottom-up A plurality of conductive terminals 2 of the body 1 .

[0033] Such as figure 1 and figure 2 As shown, the body 1 is made of insulating material, and has a plurality of receiving holes 11 arranged in a matrix through up and down, for correspondingly accommodating a plurality of the conductive terminals 2 and the plurality of conductive parts A1 of the chip module A. . Each receiving hole 11 is surrounded by two side walls 111 and two end walls 112 con...

Abstract

The invention discloses an electrical connector. The electrical connector is used for abutting a chip module and comprises a body and at least one conductive terminal, wherein at least one accommodating hole is formed in the body, a baffle block is arranged in the accommodating hole, the conductive terminal is provided with a base part, the base part is arranged below the baffle block, the base part upwards extends to form two elastic arms at two sides of the baffle block, the two elastic arms extend in a protruding way to form two contact parts above the baffle block, the distance between thetwo contact parts is smaller than the width of the baffle block, and the two contact parts prop against the baffle block downwards and are electrically connected with the chip module. During the process assembling the conductive terminal into the accommodating hole from bottom to top, the contact part can pass through the baffle block, the initial distance of the two contact parts is smaller thanthe width of the baffle block, the two contact parts prop against the two sides of the baffle block, so that the two elastic arms are expanded towards the two sides; and since the contact parts deviate from a surface of the body, the stress force arms of the elastic arms are relatively lone, so that the stress distributed on the elastic arms is dispersed, and the elastic arms are difficult to gettired.

Description

technical field [0001] The invention relates to an electrical connector, especially an electrical connector for electrically connecting a chip module to a circuit board. Background technique [0002] U.S. Patent No. 7,537,461 discloses an electrical connector, which includes a body, the body has a terminal accommodating groove, and a center member (center member) close to the bottom surface of the body is provided in the terminal accommodating groove; the conductive terminals are assembled into the terminal accommodating groove from bottom to top, The conductive terminal includes a center portion, two contact beams (beams) extending upward from the center portion, each contact beam has an interface portion (interface portion) for electrically connecting the docking element, and is located below the contact portion A protrusion (protrusion) is used to lock the middle part and prevent the conductive terminal from withdrawing downward from the terminal receiving groove. The pro...
