Abstract

The utility model discloses an electric connector, which comprises an insulation body and an electric conduction terminal. The insulation body is provided with a terminal take-in groove. The electric conduction terminal essentially comprises a body part, a welded part formed by the downward extension of the body part and an arm arranged at the upper end of the body part, wherein, the body part is positioned between the arm and the welded part and provided with a locking mechanism at the side edge. The side wall of the terminal take-in groove is provided with a projection. When the electric conduction terminal is positioned in the terminal take-in groove, the locking mechanism and the projection are matched with each other to lead the electric conduction terminal to float up and down in the terminal take-in groove. Therefore, the utility model can prevent the situation of poor welding effect or void soldering since the electric conduction terminal leaves the circuit board caused by buckling deformation of the insulation body, when the electric conduction terminal is welded on a circuit board, thus the utility model can guarantee good conductivity of electric property between the electric conduction terminal and the circuit board.

However, the design defect of this electrical connector is that: when the conductive terminal 10 accommodated in the insulating body 20 is welded to the circuit board, the insulating body 20 is deformed by heat, and the conductive terminal 20 will follow the insulation due to being stably held in the receiving groove. The warping and deformation of the body 20 separates from the circuit board, resulting in poor or empty soldering between the conductive terminal 10 and the circuit board.

Therefore, it is necessary to improve the electrical connector to solve the above-mentioned defects in the prior art.

【Content of utility model】

The purpose of the utility model is to provide an electrical connector in which the conductive terminal can float up and down in the insulating body and can achieve good welding effect during welding.

【Detailed ways】

Please refer to Fig. 3 and Fig. 4, the electrical connector (not labeled) of the present utility model can be used to electrically connect a chip module (not shown) to a circuit board (not shown), which mainly includes a conductive terminal 30 and an insulating body 40 The conductive terminal 30 mainly includes a main body 301, an arm 302 provided at the upper end of the main body 301, and a welding portion 303 extending from the lower end of the main body 301. The arm 302 is provided with an extension 3021, and the end of the extension 3021 extends substantially along the horizontal direction. There is a connection part 3022, the end of the connection part 3022 is provided with a contact part 3023 which is roughly perpendicular to the connection part 3022, and the main part 301 is located between the arm part 302 and the welding part 303 and extends to both sides with two pairs of clamping mechanisms 304. The clamping mechanism 304 is provided with an upper clamping arm 3041 and a lower clamping arm 3042 , and the upper clamping arm 3041 and the lower clamping arm 3042 are relatively substantially in the shape of a “eight” and form an opening 305 .
