Description

Electric connector

[technical field]

The utility model is about a kind of electric connector, is meant a kind of electric connector that is used on the mobile phone especially.

[background technology]

When electric connector is used for compact electronic device such as mobile phone, need reduce alignment error as far as possible, the firm connection between the insulating body that prevents to be subjected to the external force effect to destroy connector and housing, even destroy terminal or situations such as terminal distortion take place.See also Fig. 1, this electric connector 2 is to be used for being extensive use of on the mobile phone and by industry, the housing 600 that it comprises insulating body 200, is contained in the plurality of terminals 400 of insulating body 200 and is coated on insulating body 200 peripheries.Wherein insulating body 200 comprises that one offers the body 220 of plurality of terminals groove 222 in its longitudinally, and the front end of this body 220 is provided with two pairs of grooves 224 symmetrically.This housing 600 has the frame shape main part 620 of an inner hollow, and the front and rear end that this main part 620 is oppositely arranged is formed with opening 622, and extends out two pairs of buckling foots 624 from the lateral margin of its front openings 622.During assembling, from the open rearward end 622 of housing 600 housing 600 of packing into, and two pairs of buckling foots 624 of housing 600 are held on the groove 224 of insulating body 200 insulating body 200, by both buckle in conjunction with insulating body 200 is locked in the housing 600.

But, only two pairs of buckling foots 624 with housing 600 are snapped in the groove 224 of insulating body 200, this manner is firm inadequately, particularly when electric connector 2 is subjected to foreign impacts, insulating body 200 very easily breaks away from from the open rearward end 622 of housing 600, and the external force that housing 600 is subjected to is passed to terminal 400 by insulating body 200, causes the solder joint (figure does not show) of terminal 400 to be subjected to external force to be easy to generate fracture.

Therefore, need the deficiency of a kind of electric connector that can firmly assemble with the electric connector that overcomes prior art.
