Summary of the invention
The purpose of this utility model is; a kind of USB connector with protecting and have secondary locking function is provided; its simple and ingenious structure; production assembly technology is simple, and cost is lower, and easy to use; by pressing locking and the separation function that can realize repeatedly; when locking, can bear manpower and pull and can not come off, reliable and stable, thus guaranteed the stable of switching performance.
The technical scheme that the utility model adopted is for achieving the above object:
A kind of USB connector with protecting and have secondary locking function, it comprises suitable public connector and female connectors, on this female connectors, be covered with a containment vessel, this containment vessel is provided with a locking shell fragment, this locking shell fragment and containment vessel are formed in one, the middle part of this locking shell fragment is fixedly connected on the top of containment vessel, one hole clipping is arranged at the front end of this locking shell fragment, the rear end of this locking shell fragment is provided with briquetting, this hole clipping level height is lower than this briquetting, in this public connector, be provided with a fixture block corresponding with this hole clipping, in this locking shell fragment top, be provided with one and prevent that this locking shell fragment is by the protection baffle plate of clashing and breaking.This containment vessel adopts engineering plastics to make, and after locking shell fragment and fixture block locking, can bear 110N pulling force; manpower cannot be pullled and come off; be provided with protection baffle plate, thereby can effectively prevent that the junction of locking shell fragment and containment vessel is subject to external force collision, avoided affecting the service behaviour of locking shell fragment.
The side face of this female connectors is provided with some metal clipss, and on the inwall of this containment vessel, corresponding described metal clips is provided with containing groove.Thereby when being provided with containing groove and being convenient to assemble, containment vessel is installed on female connectors.
The rear end of this female connectors, to having two fixing feet, is provided with and dodges draw-in groove in the corresponding described fixing feet in the rear end of this containment vessel.Dodging draw-in groove and the cooperation of fixing feet has avoided causing containment vessel to depart from from female connectors when separated public connector and female connectors.
This protection baffle plate is located at the top of the junction of this locking shell fragment and containment vessel, and the two ends of this protection baffle plate are fixed on containment vessel, and this protection baffle plate can effectively prevent from locking shell fragment by external force collision, extends the useful life of connector.
The beneficial effects of the utility model are: its simple and ingenious structure of the utility model, production assembly technology is simple, cost is lower, and easy to use, by pressing locking and the separation function that can realize repeatedly, when locking, can bear manpower and pull and can not come off, reliable and stable, thus guaranteed the stable of switching performance.
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
Accompanying drawing explanation
