Abstract
An electrical connector can be mounted on a circuit board. The electrical connector comprises an insulation body and fixing parts arranged on the insulation body, the insulation body is provided with a bottom surface arranged on the circuit board, each fixing part is provided with a fixing pin extending downwards from the bottom surface of the insulation body, and the fixing pin is embedded on the circuit board and welded on the same through a method of immersing the pin into solder paste. The fixing parts utilize a welding form of immersing the pins into solder paste, and then the electrical connector occupies little space of the circuit board and is stable in connection.
Description
[technical field]
The utility model is about a kind of electric connector, especially relates to electric connector and is fixed in fixture on the circuit board.
[background technology]
Socket connector of the prior art uses surface soldered technology (SMT) widely.The SMT welding has advantages such as the weldment of minimizing volume, welding portion stable performance.Yet, the socket connector of traditional SMT structure, after being welded on the circuit board, the grabbing plate force deficiency.Particularly when plug is pulled out under abnormal condition, easily cause and adopt the terminal of SMT welding to come off, finally influence the normal use of product.
TaiWan, China patent M275579 patent has disclosed a kind of socket connector of stack.This electric connector for socket is provided with insulating base frame and is arranged on the retaining element of insulating base frame bottom surface.This retaining element is provided with the fixing feet of the bending of downward extension.This fixing feet interferes connected mode to be mounted to circuit board by perforation.Yet this perforation interference connected mode takies the space of more circuit board, and this connected mode unstable properties.
Therefore, be necessary existing technology is improved to overcome above-mentioned defective.
[utility model content]
Technical problem to be solved in the utility model is: the electric connector that the less and fixture that switching performance is stable in a kind of space of the circuit board that has strong grabbing plate force, takies is provided.
Technical problem to be solved in the utility model passes to down technical scheme and realizes: a kind of electric connector, can be installed on the circuit board, described electric connector comprises insulating body and is arranged at the fixture of this insulating body, described insulating body is provided with the bottom surface that is installed on described circuit board, described fixture is provided with the fixing feet of extending from the bottom surface of described insulating body downwards, and described fixing feet is embedded into and immerses the tin cream method by stitch on the described circuit board and be soldered to this circuit board.
Compared to prior art, the fixture of the design's electric connector adopts stitch to immerse the tin cream welding manner, and the space of the circuit board that can take is less, and switching performance is stable.
