Electrical connector and terminal

Abstract

The invention discloses an electrical connector for electrically connecting a chip module having a plurality of conductive pieces at the bottom. The electrical connector includes an insulating body for carrying the chip module, with a plurality of receiving holes penetrating vertically through the insulating body; and a plurality of terminals being correspondingly received in the receiving holes and having at least two elastic arms. Two contact portions protrude upward at the inner sides of the two adjacent elastic arms, so that the contact portions are higher than the upper surfaces of the elastic arms. The outer sides of the elastic arms are spaced apart from the contact portions, and the two contact portions abut upward on the same conductive piece, so that the contact area between theterminals and the conductive pieces is small. Further, the contact portions are ensured not to easily run out of the conductive piece, the outer sides of the contact portions are prevented from sliding out of the conductive piece to abut against other components on the chip module that are lower than the conductive piece, the problem that the contact portions are disengaged from the conductive piece is then avoided, the risk of non-conduction between the terminals and the chip module is reduced, and stable contact between the electrical connector and the chip module is ensured.

Description

technical field [0001] The invention relates to an electrical connector and a terminal, in particular to a plane grid array electrical connector and a terminal for electrically connecting a chip module to a circuit board. Background technique [0002] The Chinese patent No. 200420054523.6 discloses an electrical connector, which includes an insulating body with a receiving hole, and conductive terminals accommodated in the receiving hole to connect the chip module and the circuit board. It mainly includes a main body and a main body The upper and lower sides of the upper and lower sides are provided with obliquely extending arms. The end of the arm is provided with a contact portion that is connected to the electronic component. At least one side of the main body is provided with at least two arms, so as to ensure that the electrical connector terminal is in contact with the chip module or Better electrical conduction performance between circuit boards. [0003] However, th...

AI Technical Summary

Problems solved by technology

[0003] However, this electrical connector has at least the following disadvantages: due to the manufacturing tolerances of the chip module, there is a height difference in the circular conductive sheet located on the bottom surface of the chip module, so that part of the conductive sheet is higher than other surrounding components, and the contact portion and the chip module The contact area is large, and the height of the contact part is consistent from the inside to the outside. When the chip module presses down on the terminal, the outer side of the contact part is far away from the center of the conductive sheet, so it is easy to slide out of the conductive sheet of the chip module and contact with the conductive sheet. Other components on the chip module that are lower than the conductive sheet are in contact, causing the contact part to be out of contact with the conductive sheet, causing the conductive terminal to be disconnected from the chip module
