Further, a plurality of tail grooves are formed in the tail surface of the rubber core, and the tail ends of the pin needles are located in the tail grooves.

Furthermore, after the pin needle is positioned in the rubber core, a plurality of pin holes I are formed in the rubber core.

Further, after the end part of the pin needle is led out from the rubber core, the pin needle extends to the inside of the rear cover, and a plurality of second pinholes are formed in the inside of the rear cover.

Furthermore, the shape of the clamping groove and the clamping block are matched.

Furthermore, the lower part of the rubber core (1) and the first pin hole (12) are arranged as a row of a plurality of hole sites.

Further, the rear cover (2) is provided with one row or two rows of pin hole two (21) hole position slots.

The utility model provides an electric connector. Compared with the prior art, the method has the following beneficial effects:

this lid behind electric connector buckle formula, through redesigned right triangle's block structure between rubber core and the back lid, when electric connector actual production, lid 90 behind the upset can directly let rubber core and back lid block be in the same place, need not to increase a horizontal pushing action like prior art any more, present new block structure can save this action to can accelerate production efficiency, through this buckle mode, the direct block is fixed, and the back lid after the combination is more steady difficult not hard up in addition, can realize automated machine production.
