Detailed ways

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

The utility model is described below with reference to Fig. 1 to Fig. 4 .

A connector, comprising an insulating base body 1 and a metal contact piece 2, the metal contact piece 2 is in the shape of a sheet, the metal contact piece 2 includes a fixing part 21 inserted in the insulating base body 1, the fixing part 21 The upper end extends to the outside of the insulating seat body 1 and bends to form a solder leg 22, which is welded to the light source board 4, and the lower end of the fixing part 21 is bent to the inner side of the insulating seat body 1 and extends obliquely upward to form an elastic contact piece 23 The end of the elastic contact piece 23 is bent and extended toward the fixed portion 21 to form a limiting portion 24; the insulating base 1 is provided with a slot 11 that is engaged with the fixed portion 21 and an accommodating cavity for accommodating the elastic contact piece 23 12. Electrical connectors such as pins are inserted into the accommodating cavity 12 of the insulating base 1, and the pins force the elastic contact piece 23 to deform and be clamped by the elastic contact piece 23 to realize a stable electrical connection. When the elastic contact piece 23 deforms too much When it is too large, the limiting portion 24 will abut against the fixing portion 21 to prevent the elastic contact piece 23 from being further deformed, so as to ensure the stability of the electrical connection of the elastic contact piece 23 .

The insertion opening of the accommodating chamber 12 is set outwards, which facilitates the insertion of electrical connectors such as pins 5 into the connector.
