Problems solved by technology

[0003] However, this assembly method has the following defects: when the base and the lower cover are placed on the circuit board, due to the different weights at both ends of the lower cover, there is a certain inclination between the base and the circuit board when welding with the circuit board, which may cause Poor welding between the terminal and the circuit board will affect the electrical connection between the electrical connector and the circuit board. In addition, during the installation process of the base and the lower cover, the base will be warped due to extrusion, which may also cause the terminal to be damaged. Poor soldering to the circuit board affects the electrical connection between the electrical connector and the circuit board

Embodiment Construction

[0015] see figure 2 , image 3 The electrical connector of the present invention includes a metal lower cover 10, a metal upper cover 20 pivotally connected to one end of the lower cover 10, and a rocker 30 pivotally connected to the other end of the lower cover 10 for buckling and fixing the upper cover 10 and the lower cover 20, And a base 40 fixed on the lower cover 10 for carrying a chip module (not shown in the figure).

[0016] The upper part of both sides of the base 40 is provided with a number of longitudinal slots 42, the outer edges of the slots 42 extend from the outside to the inside, and a protrusion 43 is formed between adjacent slots, and a transverse horizontal slot communicating with it is provided below the slots 42. Channel 44.

[0017] A through hole 22 is defined in the center of the lower cover 20 . Several protrusions 24 extend inward from both sides of the through hole 22 . The protrusions 24 correspond to the slots 42 on the base 40 and are slightl...

Abstract

The electric connector comprises lower cover and base to be fixed with each other. Several lognitudinal slot openings are setup at upper part on two sides of base, and transverse channels are located under the slot openings and connected to the openings. A through hole is at central position of the lower cover in the rough. There are several lugs on two lateral margins of the through hole towards inside. These lugs corresponding to slot openings on base is smaller than size of slot openings. Method for assembling electric connector includes welding electric connector onto circuit board. First, a base is welded to circuit. Then, lower cover is installed on the base. When circuit is welded, it is not needed to setup lower cover on base so as to prevent inclination and warp of base from happening. The invention guarantees good contact effect between electric connector and circuit board.

Description

【Technical field】 [0001] The invention relates to an electrical connector and an assembly method thereof, in particular to an electrical connector for electrically connecting a chip module and a circuit board and an assembly method thereof. 【Background technique】 [0002] figure 1 What is shown is a conventional electrical connector, which is welded on a circuit board to enable indirect electrical conduction between the chip module and the circuit board. The electrical connector includes a metal lower cover 1, a metal upper cover 2 pivotally connected to one end of the lower cover 1, a rocker 3 pivotally connected to the other end of the lower cover 1 for buckling and fixing the upper cover 1 and the lower cover 2, and a fixed On the lower cover 1, there is a base 4 for carrying the chip module (not shown in the figure), and a number of terminals (not shown in the figure) are accommodated on the base 4, so that the chip module and the circuit board (not shown in the figure)...
