Summary of the invention
The purpose of this utility model is to provide a kind of electric connector high pressure anti-telegram in reply protective device, guarantees operating personnel's safety.
The purpose of this utility model is achieved by the following technical programs:
The anti-high pressure telegram in reply of a kind of electric connector protective device, comprise that 4 electric power connect contact, insulation shell, insulating coating cylinder, insulating sleeve pipe and stage clip, described electric power connects contact rear end through insulation shell inner panel, by clamp nut and packing ring, is fixed on insulation shell inner panel; Described insulating coating jacket casing is contained in electric power and connects contact front end outside, and insulating coating tube rear end is fixed on insulation shell inner panel; Insulating sleeve pipe is inlaid in insulating coating cylinder and electric power connects between contact, and compression spring sleeve connects on contact at electric power, and between insulating sleeve pipe and insulation shell inner panel.
The purpose of this utility model can also further realize by following technical measures:
The anti-high pressure telegram in reply of aforesaid electric connector protective device, wherein insulating sleeve pipe box is contained in insulating coating cylinder, insulating coating cylinder front end is provided with in the insulating coating cylinder that internal diameter is less than insulating coating cylinder endoporus and turns over circle, insulating sleeve pipe rear end is provided with insulating sleeve pipe that external diameter the is greater than insulating sleeve pipe external diameter circle that turns up, stage clip one end is resisted against insulating sleeve pipe and turns up circle above, and the stage clip other end is resisted against on insulation shell inner panel; When insulating sleeve pipe moves on to extreme position outward, the insulating sleeve pipe circle lateral surface that turns up is resisted against and in insulating coating cylinder, turns on circle medial surface.
The anti-high pressure telegram in reply of aforesaid electric connector protective device, when wherein electric connector does not connect, insulating sleeve pipe external port connects contact outer face, both distance L=1～2mm higher than electric power.
The anti-high pressure telegram in reply of aforesaid electric connector protective device, the material of wherein said insulation shell is pottery, the material of insulating coating cylinder and insulating sleeve pipe is plastics.
The utility model is simple in structure, easy to use, quick be connected or separated that can effectively realize jump lead and power supply.At electric power, connect the insulating sleeve pipe that one of the outer suit of contact can elastic telescopic, and electric connector is not when connect, insulating sleeve pipe external port connects contact outer face higher than electric power, prevents human body false touch electric power connection contact, avoids occurring electric shock accidents.When electric connector is pegged graft, automatic retrude after insulating sleeve pipe pressurized, stage clip is by compression; After electric connector is extracted, stage clip reset auto-extending insulating sleeve pipe, the electric connector of protection plug at any time operating personnel's safety, avoids it to come to harm.
Advantage and disadvantage of the present utility model, the non-limitative illustration by preferred embodiment below is for illustration and explanation, and these embodiment, only provide as an example with reference to accompanying drawing.
