Background

The DDR memory connector is generally provided with (at least one end is provided with) a top clip (back clip) ear clip at one or both ends of the main body, and the ear clip is pivotally connected to the connector main body through a pivot. The bottoms of one end or two ends of the main body are provided with iron feet which are welded and fixed on the PCB. When iron feet and PCB board are welded, for better welding, soldering flux is generally added before welding, but excessive soldering flux can climb to the main body along the iron feet and then adhere to the earrings, so that the earrings are not smooth to open and close, and the experience of users is seriously affected.

Chinese patent CN2019113585887 discloses an electrical connector for electrically connecting a circuit board, the circuit board having a soldering hole, comprising: the insulation body is provided with a slot extending along the longitudinal direction and a tower part arranged on one longitudinal side of the slot, the tower part is provided with a containing cavity and a mounting groove, and the containing cavity vertically penetrates through the tower part and forms an opening on the bottom surface of the tower part; the terminals are arranged on the insulating body and distributed on at least one side of the slot; the ear clip is accommodated in the accommodating cavity and pivoted to the tower part, and is positioned above the opening; the fixing piece is provided with an installation part which is inserted upwards and fixed in the installation groove, a welding part which is inserted downwards into the welding hole and a shielding part, the shielding part is positioned below the tower part, the shielding part covers the part of the welding hole opposite to the opening in the up-down direction, and the longitudinal direction is perpendicular to the up-down direction; the opening is provided with two side edges which are opposite in the transverse direction, the welding hole is positioned between the projections of the two side edges on the circuit board, the shielding part covers the opening in the transverse direction, and the transverse direction, the longitudinal direction and the upper and lower directions are mutually perpendicular.

According to the electric connector, the retainer with the shielding part shields the opening formed on the bottom surface of the tower part of the insulating body, so that soldering flux evaporated from the welding hole cannot spread upwards towards the opening, and the phenomenon that the soldering flux is condensed at the position where the tower part and the earring are pivoted mutually to cause that the earring cannot be pivoted with the tower part smoothly is avoided.

Although the fixing member of the above electrical connector can enable the earring to be opened and closed smoothly, the above electrical connector still has drawbacks: the welding part and the shielding part are of an integrated metal structure, the welding part is fixed on the circuit board in a welding way, and the problem that soldering tin upwards spreads to the opening during welding exists, so that the smooth opening and closing of the earring are affected.
