Abstract
The utility model discloses a wire strand breakage prevention protection device which can effectively prevent the strand breakage between a copper wire of a short-circuit ground wire for a power system and a wiring terminal. The wire strand breakage prevention protection device comprises a wiring terminal, a plurality of copper wires which are covered by an insulation protection layer, a spring sleeve, and a thermal shrinkage insulation protection sleeve. According to the device, through adding the spring sleeve on the wiring terminal and forming the thermal shrinkage insulation protection sleeve outside the spring sleeve, a disadvantage that a connection part between the tail end of the wiring terminal and the copper wires is easily folded and broken is completely solved, and thus the personal safety of an operator in the process of ground operation is ensured.
Description
Technical field:
The utility model relates to a kind of conductor from break thigh protective device, relates in particular to the protective device of anti-breaking strand between a kind of copper conductor and the binding post interface that can effectively protect electric power system short-circuit grounding wire.
Background technology:
The short-circuit grounding wire that power industry is conventional, one of main member is exactly the copper conductor by two ends band binding post, due to the cause of Reusability, the tail end of binding post and the junction of copper conductor are easy to occur folding around breakage, form the fracture of copper conductor part and outer insulating layer coating and break, very easily cause personal injury.
This device passes through at the additional shock mount cover of binding post, and shrinks insulating sleeve sizing at spring housing outside reusable heat, has thoroughly solved above-mentioned drawback, thereby guarantees the personal safety of operating personnel in ground connection operating process.
Summary of the invention:
The purpose of this utility model is to provide a kind of conductor from break thigh protective device, neither destroys original structure pattern, guarantees again the personal safety of operating personnel in short circuit grounding operating process.
Technical conceive of the present utility model is as follows: design a kind of spring housing that simultaneously wraps up binding post and partial-length wire; utilize the stretching of spring, flexible characteristic; be socketed on binding post fixing; and with the multiply copper conductor of binding post crimping meeting with when bending; itself and binding post tail end junction are in the protection of spring housing all the time; be difficult to form low-angle bending, reach and avoid the fracture of copper conductor and the object that outer insulating layer coating breaks.
For achieving the above object, the utility model provides a kind of conductor from break thigh protective device, and this protective device comprises:
One binding post, its upper end is connected with short-circuit grounding wire associated components by metal connecting piece, lower end endoporus and copper conductor crimping, lower end is outside to be socketed with spring housing;
The one outer multiply copper conductor that covers insulating protective layer, its one end and binding post crimping;
One spring housing, the outside socket in its inner ring upper end and binding post lower end, its inner ring lower end wrapping portion length wire, its outer ring is by heat shrinkage insulation protective sleeve shrink wrapped;
One heat shrinkage insulation protective sleeve, carries out thermal contraction parcel to spring protecting jacket outer ring.
Preferably there are a connecting through hole and a positioning through hole in the upper end of described binding post, and metal connecting piece is connected binding post by connecting through hole with short-circuit grounding wire associated components, and positioning through hole coordinates location with short-circuit grounding wire associated components.
Preferably described metal connecting piece is a fastener assembly.
Preferably described copper conductor be surrounded by the multiply of insulating barrier can flexible bending wire.
Preferably described spring housing is a multi-circle spiral flow shape spring, can stretch, flexible.
Preferably described heat shrinkage insulation protective sleeve is the heat-shrink tube of internal diameter corresponding to multi-circle spiral flow shape spring outer diameter.
Preferably described heat shrinkage insulation protective sleeve is carried out thermal contraction parcel to multi-circle spiral flow shape spring outer ring.
The principle of this conductor from break thigh protective device is: with the copper conductor of binding post, in use can occur folding around, particularly the junction of binding post tail end and copper conductor is easy to occur damaged, forming the fracture of copper conductor part and outer insulating layer coating breaks, but implementing after conductor from break thigh protective device, copper cash and binding post junction are in the protection of spring housing all the time, because upper end and the terminal of spring housing are that rigidity is socketed and fixes, the lower end of spring housing and copper cash are gap sockets, be difficult to form folding around, thereby the fracture of copper conductor and breaking of outer insulating layer coating are avoided, shrink insulating sleeve sizing at spring housing outside reusable heat simultaneously, play the effect of multiple protective.
The utility model is owing to having adopted above technical scheme; make it compared with prior art; stop the junction of binding post tail end and copper conductor due to breakage; form the potential safety hazard that the fracture of copper conductor part and outer insulating layer coating break; improve the coefficient of safety of construction operation, protected operating personnel's personal safety.
Accompanying drawing explanation:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of conductor from break thigh of the utility model protective device.
Specific implementation method:
As shown in Figure 1, the utility model embodiment is a kind of a kind of preferred version of conductor from break thigh protective device.This device comprises: binding post 1; Fastener assembly 2 is connected with short-circuit grounding wire associated components 4 by the connecting through hole 3 of binding post 1 upper end, and the positioning through hole 5 of binding post 1 upper end forms to coordinate with short-circuit grounding wire associated components 4 and is located by connecting; Copper conductor 6; After binding post 1 lower end endoporus 7 inserts the copper conductor 6 of peelling off insulating protective layer, carry out cold weld, cold weld is at the outside impression groove 8 that produces of binding post 1, and binding post 1 forms close contact conducting with copper conductor 6 thus; Spring housing 9, its inner ring top and binding post 1 lower end external rigidity are socketed and fix, and its inner ring bottom is to 6 containment roles of partial-length copper conductor, and thermal contraction parcel is carried out by heat shrinkage insulation protective sleeve 10 in its outer ring.
Above-mentioned conductor from break thigh protective device, simple in structure, easy to operate, and security performance is reliable, has larger implementation result.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for utility model is described, and be not used as restriction of the present utility model, as long as within the scope of connotation of the present utility model, variation, distortion to the above embodiment all will drop within the scope of claims of the present utility model.
