Background technology
Power failure, electrical verification before the power construction and articulate the protective ground line step that is absolutely necessary; Wherein be connected with the frequent use that connects torch of earth connection; The crimp segment (being end section and one little section revealed section that earth connection inserts copper sleeve) that makes earth connection and copper sleeve carry repeatedly, take out stitches, in the wiring process by repeatedly bending back and forth; Be prone to cause the insulating barrier and the earth connection fracture at this place, thereby cause whole earth connection damage and bring potential safety hazard to construction.
The utility model content
The utility model purpose provides a kind ofly establishes the earth connection of spring housing in crimp segment, and it is strong that it has the bending ability, the characteristics of long service life.
The utility model is following for the technical scheme that solution prior art problem is adopted: a kind of earth connection of establishing spring housing in crimp segment; Comprise copper sleeve, be connected the earth connection of copper sleeve one end; The crimp segment that it is characterized in that said earth connection and copper sleeve is provided with spring housing, and described spring housing is wrapped in the surface of crimp segment.When earth connection receives tractive; Because the spring housing of setting up is the torsion spring structure; Not only can bear the suffered external force of part crimp segment like this but also can this external force be passed; Thereby the crimp segment of protective earthing line and copper sleeve, the earth connection that prevents this place damages because of tractive bending repeatedly.
Describedly a kind ofly establish the earth connection of spring housing in crimp segment, the external diameter that it is characterized in that internal diameter and the earth connection of described spring housing adapts and spring housing is crimped on the copper sleeve tail end, can make spring housing be fixed on the crimp segment place under normal conditions like this.
Describedly a kind ofly establish the earth connection of spring housing, it is characterized in that earth connection is that the multiply copper core coats rubber layer outward, is wrapped on the rubber layer to described spring housing matched in clearance in crimp segment.
Describedly a kind ofly establish the earth connection of spring housing in crimp segment, it is characterized in that spring housing by wire loop around forming, the steel wire of an end mutually near circle around, the steel wire of remainder leave the gap geosphere around, be crimped on the copper sleeve around end near circle.The crimp segment that this circle can effectively firmly be buckled dead earth connection one end around mode makes it can't break away from copper sleeve under the effect in external force, has improved its bend resistance ability simultaneously, to adapt to the needs that articulate of varying strength.
Describedly a kind ofly establish the earth connection of spring housing in crimp segment, the external transparent insulation cover of said spring housing is provided with this insulating case crimp segment that can insulate, and can judge the state (whether rupturing) of crimp segment again.
Describedly a kind ofly establish the earth connection of spring housing in crimp segment, the spring housing two ends are crimped on copper sleeve tail end and earth connection one end respectively.
Describedly a kind ofly establish the earth connection of spring housing in crimp segment, spring housing one end and copper sleeve crimping, the other end is a free end.
Describedly a kind ofly establish the earth connection of spring housing in crimp segment, the length range of spring housing is 5～10cm.
Describedly a kind ofly establish the earth connection of spring housing, it is characterized in that spring housing is the flexible metal cover in crimp segment.
The utility model has been optimized ground line configuration; Establish the bend resistance ability that spring housing can increase earth connection in the crimp segment of earth connection; Avoid repeatedly amounting to back and forth the security hidden trouble that the insulating barrier cracky that causes crimp segment and ground connection copper cash easy fracture are brought; Coefficient safe in utilization is high, and it is low to improve cost, is easy to promote.

Embodiment
Be further described below in conjunction with Figure of description and embodiment substantive distinguishing features the utility model.
As shown in the figure; A kind ofly establish the earth connection of spring housing in crimp segment, comprise copper sleeve 1, this copper sleeve can be divided into two parts; Wherein link is flat; Have the through hole that can supply screw to wear on it, but the other end is the ring cavity of capacity earth connection, the earth connection 3 that is connected copper sleeve one end is to be constituted and coated rubber layer outward by the multiply copper core; The crimp segment 2 of earth connection 3 and copper sleeve 1 is wrapped in the surperficial spring housing 4 of crimp segment 2 with being provided with matched in clearance, this spring housing 4 be by the steel wire coiling and length range between 5-10cm.In addition, near enclosing around being crimped on copper sleeve 1 tail end, the external diameter of its internal diameter and earth connection 3 adapts spring housing 4 one ends through steel wire, and the remainder steel wire leaves the gap geosphere on earth connection 3.Spring housing 4 external transparent insulation covers 5, the crimp segment that can insulate can be observed the state of crimp segment again.
The spring housing of said wire spring can be set up following two kinds of modes that are crimped on copper sleeve: one of which is that the spring housing two ends are crimped on copper sleeve 1 tail end and earth connection 3 one ends respectively; Another kind is spring housing one end and copper sleeve 1 crimping, and the other end is a free end.
The utility model is applicable to that the three-phase coupling type connects the earth connection of torch; Its occupation mode is following: establish spring housing 4 in the earth connection 3 and the crimp segment 2 of copper sleeve 1 earlier; The copper sleeve 1 that will be connected with earth connection 3 again is fixed on and connects connecing on electricity folder 7 relevant positions on the torch 6, constitutes the protective ground line.During hanging earthing conductor: link earlier earth clip 8, after connect electricity folder 7; When removing earth connection 3, must follow procedure disconnect electricity earlier and press from both sides 7, after tear earth clip 8 open.
The earth connection that the three-phase coupling type connects torch is to be used to prevent that equipment, circuit from sending a telegram here suddenly, eliminates induced voltage, drains the temporary grounding device of residual charge, uses the earth connection after the improvement not only to improve its bend resistance ability, has also prolonged its useful life.
Another execution mode of the utility model does, spring housing 4 can be made with the flexible metal cover, and all the other structures and the foregoing description basically identical repeat no more.
