Detailed description of the invention
It is described in detail the utility model with reference to the accompanying drawings and detailed description;
Fig. 1 is traditional tag schematic diagram;
Fig. 2 is the structural schematic diagram of the utility model;
Fig. 3 is the assembling schematic diagram of the utility model.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below In conjunction with specific embodiment, the utility model is further described.
Referring to Fig. 2-3, present embodiment uses following technical scheme: it is touch separation type power cable connecting piece used, Including external shielding layer 1, insulating layer 2, inner conducting layer 3, inner cone structure 4, capacitive test point 5, ground hole 6 and integral type stress cone 7, Insulating layer 2 and external shielding layer 1 are disposed with outside inner conducting layer 3,3 one end two sides of inner conducting layer are provided with and external electric appliance phase Inner cone structure 4 even is provided with integral type stress cone 7, integral type stress cone 7 on the external shielding layer 1 outside 3 other end of inner conducting layer On be provided with ground hole 6, capacitive test point 5 is additionally provided on insulating layer 2.
It is worth noting that, the insulating layer 2, inner conducting layer 3 are integral type composite construction.
It is worth noting that, the capacitive test point 5 uses embedded metal component.
It is worth noting that, the integral type stress cone 7 is funnel-form.
In addition, the inner cone structure 4 is separately connected bushing and insulation plug.
The external shielding layer 1 of present embodiment makes the outer surface of detachable connector keep zero potential, and electrification can touch It touches, is not necessarily to exterior insulation distance.Insulating layer 2 is reliably isolated by high-field electrode with ground electrode, bears operating voltage and various excessively electric Long term is pressed, therefore its electric strength and performance steady in a long-term are to guarantee that entire separable connector completes the weight of transmission of electricity task Want part;It also wants the heat effect that can feel bad heating conductor and keeps due dielectric strength.Inner conducting layer 3 uses semiconductive rubber Glue sulfidization molding, is combined into one with major insulation.It is in the air-gap of cable conductor junction under equipotential, Bu Huifang Electricity, cable insulation end does not need cutting reagency cone, even if cable insulation has axial shrinkage, as long as its end is not reduced to connector Other than interior semi-conductive layer, joint performance would not be influenced.It keeps field distribution uniform, and operation is safer, and eliminating may deposit Potential danger, make the power cable connecting piece service life extend.Inner cone structure 4 is used to connect with other electrical parts.Capacitive test Point 5 uses embedded metal components, there is that certain potentials are poor when charging operation, between metal parts and external shielding layer, can be with For installing electrification display, it can also be shorted and shield by semiconductive cap test.Ground hole 6 is used to connect external shielding layer Ground.Integral type stress cone 7 is also known as stress cone, improves the electricity of power cable external shielding layer gap by funnel-form stress cone Field distribution, it simultaneously or different size cable adapter.
