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 telecommunication connects between two electronic systems that is applied to.

Wire and cable connector is commonly used to cooperate cable connecting different electronic installations, thereby signal transmission fast between the two is provided, and wire and cable connector also need have stable fixing state except that need have higher transmittability, be difficult for interrupting to guarantee the telecommunication transmission.In addition, wire and cable connector is because cable itself carries out the long range signals transmission, thereby to electromagnetic interference sensitivity especially, so whether weigh the wire and cable connector quality good, its function of shielding is one of major criterion.No. 84201894 case of TaiWan, China patent application disclosed a kind of existing wire and cable connector, its insulating body outside is typically provided with the metallic shield housing, coat and reach the effect of electromagnetic shielding so as to the insulating body that will contain conducting terminal, and both are placed in the shell body simultaneously.And the metal baffle adopts dual mode and insulating body Joint usually, a kind of be appropriate location, metal baffle bottom surface respectively housing and insulating body punching out outward button is arranged, and on shell body and the corresponding position of insulating body, be provided with button hole, fasten mutually by button and button hole and be one baffle and insulating body winding.Another kind is to be provided with button hole on the metallic shield housing, and is provided with button in the relevant position of shell body and insulating body, and both fastenings can be one with baffle and insulating body winding also.

Following problem often appears in the structure of above-mentioned existing wire and cable connector in practice: because it is interlocked by button hole on baffle and the insulating body and button and reaches fixing effect, but under the long-term situation of using and often plugging, wear phenomenon may take place in the insulating body of connector or the button on the shell body or button hole, and the contact engaging and separating force in the docking operation is improper or the external force effect, all may cause baffle, button on insulating body or the shell body or button hole deform or bend, make insulating body or housing can't borrow its button or button hole to remain valid to detain and hold, cause baffle can't remain on original position.Moreover; though the effect of the baffle tool shielding protection of existing wire and cable connector; yet baffle is not provided with grounding construction, can not be effectively before wire and cable connector butt joint with electric connector with static remove rapidly, and influence stability and the quality that telecommunication is transmitted in the cable electric connector.In addition, existing wire and cable connector be provided with usually retaining component with dock electronic component and buckle mutually to hold and avoid this wire and cable connector to deviate from.And the holding unit that described designing institute adopts is for asking simple in structure and slimming, and its retain strength and structural strength are comparatively not enough, like this under permanent use easily because of elastic fatigue lost efficacy, cause the instability of assembling.

The purpose of this utility model is to provide between a kind of each member in conjunction with firm, and connector body is deviate from the time of can preventing to dock, and the good ground connection effect of tool is to realize the wire and cable connector of comprehensive shield effectiveness.

For reaching above-mentioned purpose, the appropriate location, front shroud portion two sides of the utility model cable connector body respectively is provided with at least two stoppers towards extending away from direction mutually, and baffle is provided with first baffle and second baffle of snapping mutually, and be equipped with at least two fastening holes on each baffle bottom surface, this fastening hole just can be interlocked with described stopper, so that the firm winding between first and second baffle and the insulating body to be provided, and provide electrical path between the two simultaneously.Not only can effectively shield the interference of external electromagnetic by this baffle to terminal; also can with on it and the electrostatic charge of being assembled on the cable import front shroud portion by stopper; during butt joint this front shroud portion further with the earthed circuit conducting of docking electronic installation, thereby electrostatic charge is eliminated to reach excellent electrical property protection effect.

Compared with prior art, advantage of the present utility model is: in conjunction with closely, be difficult for looseningly between each parts of wire and cable connector, and this wire and cable connector has good shielding and ground connection effect, and is quite firm with engaging of butt connector.
