Description

Wire and cable connector

The utility model is a kind of wire and cable connector, relates in particular to a kind of wire and cable connector that is used for telecommunication conducting between two electronic systems.

The TaiWan, China patent waits for No. 84201894 document to disclose a class and is applied to the existing wire and cable connector that telecommunication connects between two electronic systems; usually this class wire and cable connector is provided with the metallic shield housing; envelope the purpose of covering protection so as to the insulating body of establishing conducting terminal in inciting somebody to action to reach; and this shield shell further is assembled in the outer cover, thereby is assembled into a complete wire and cable connector.Simultaneously, in wire and cable connector butt joint plug, be unlikely, holding unit need be set be usually stablized because of phenomenon loosening or that deviate from takes place the plug application of force for avoiding insulating body and shield shell.The existing common a kind of fixing mode of wire and cable connector be on the metallic shield surface of shell appropriate location of wire and cable connector on outer cover and the insulating body direction the recessed button of punching out to a side, corresponding respectively again being buckled in the button hole of institute's relative set on outer cover and the insulating body held effect to produce local button.Another kind of mode then is that button hole is set on housing, fastens to provide salient point set on outer cover and the insulating body to protrude in it.

The button of above-mentioned existing wire and cable connector is held mode, owing to must borrow metal shield shell so that the fixing effect to be provided simultaneously, and be easy to cause it that temporary transient distortion or bending vertically take place under the unsuitable situation of contact engaging and separating force in vibration or external force or even plug process, and the salient point etc. that causes connector body or the housing button that can't remain valid is held, will shield shell can't be remained on the former allocation and have deviate from may.In addition, under the long-term state that uses and often plug, salient point on connector body or the outer cover or button hole also may produce wear phenomenon, so also the problem that can cause connector body or shield shell to deviate from easily.

The purpose of this utility model is to provide a kind of wire and cable connector, can prevent to produce between each member of wire and cable connector loosening even break away from, it can firmly be assembled into one all the time, and be provided with the purpose that grounding construction is eliminated electrostatic interference to reach, ensured the telecommunication stable transfer.

The purpose of this utility model is achieved in that wire and cable connector is made of members such as outer cover, shield shell, connector bodies, wherein a side of connector body is provided with the docking section, an end of plurality of conductive terminals promptly place this docking section and can with dock electronic installation butt joint conducting.Shield shell is covered in the periphery of connector body, and it comprises upper and lower two housings, and its side with respect to the connector body docking section is provided with the usefulness of opening for butt joint, and opposite side then is provided with through hole for connecting and fixed cable relatively.Outer cover then cover cap outside shield shell, it is covered by upper and lower two lids and forms, its example with respect to the connector body docking section is provided with craft port, this port can be wherein ccontaining so that dock plug for the docking section of connector body, relatively the another side then be provided with connect the hole can be for connecting and fixed cable.Of the present utility model being characterised in that, the inner surface of at least one lid is provided with the fixing structure in the upper and lower cover body, this fixing structure comprises and is convexly set near the lip-deep projection craft port both sides, and be located near the through hole of opposite side and therewith projection at a distance of the reference column of specific range.

In addition, the surperficial appropriate position of at least one shield shell convexes with several lugs towards its internal direction, and suitably extend and be bent to form ground plate towards its open outer side direction in its surface, this ground plate can contact conducting with the earthed circuit of butt joint electronic installation during butt joint, and provides wire and cable connector ground connection to eliminate the effect of static.Can borrow structures such as the projection of lug, lid of described housing and reference column to be resisted against in the locating structure of relative set on the connector body, in case produce loosening even disengaging between each member of principal vertical line cable connector, and connector body can not deviate from outside the wire and cable connector before and after butt joint.

Since the utility model be directly between its connector body and outer cover, assemble fixing, and be equipped with between its each member can corresponding cooperation fixing structure, thereby the steadiness of its assembling and globality are better than existing wire and cable connector, produce loosening in the time of can avoiding docking between its each member even deviate from, and owing to be provided with ground plate, it has the effect of better elimination static.
