Description

Connector improves structure

Technical field

The utility model relates to connector and improves structure, is meant a kind of simple structure, assembling facility especially and locatees firm connector construction.

Background technology

Common plug-in connector structure, just like Fig. 1, shown in Figure 2, it is No. the 405765th, TaiWan, China patent announcement " composite type double socket computer connector " patent case, it mainly is made up of last connector 7 and lower connector 6, and these lower connector 6 end faces are provided with an outer dovetail seat 61, and the position is provided with an inner dovetail groove 62 therebetween, be provided with an external dovetail groove 71 and should go up connector 7 bottom surfaces, and the position is provided with dovetail seat 72 in therebetween, must make the external dovetail groove 71 of connector 7 bottom surfaces, interior dovetail seat 72 is connected to the outer dovetail seat 61 of lower connector 6 end faces, on the external dovetail groove 62, be assembled in lower connector 6 tops will go up connector 7; Yet, said structure, though it can provide the slotting Slipped Clove Hitch between two connectors to close, but there is no suitable positioner, therefore, even upper and lower connector 7,6 mutually combines by stacked inner dovetail groove seat 72, the relative external dovetail groove seat 61 with another of external dovetail groove 71, inner dovetail groove 62, but the reverse application of force or be subjected to abnormal collision, extruding, still might cause between two connectors to get loose, this is a CR Critical shortcoming.

Therefore, the application of No. 553548 " plug-in connector improvement structure " patent case that this case inventor has the Taiwan patent announcement, its primary structure comprises: lower connector, intermediate connector reaches parts such as going up connector, wherein each connector is provided with the protruding dovetail and the dovetail groove of intercalation mutually respectively at interface, but and be provided with one in the interior extension end of this protruding dovetail and extend in parallel and the elasticity fork hook of elastic dilatation, and the faying face of the interior elongated end of each dovetail groove is provided with the positioning jack of mutual correspondence, utilize this elasticity fork hook to embed and form stopper in the positioning jack, can make location, different connector combination back, yet, though it is good combined strength that this kind structure has than the box-like connector of traditional group, but still has improved space, and each connector in conjunction with after be make conducting terminal be in adjacent and without hindrance every state, very easily be out of shape because of improper external force effect, form the unusual of contact short circuit, so, in addition improved necessity is arranged.

Because common plug-in connector structure has above-mentioned shortcoming, the inventor has the utility model to produce at the road of those shortcoming research improvement finally.
