Abstract
The utility model relates to a cable joint point sealing device which comprises an outer sleeve, an elastic insert and annular grooves. The outer sleeve is coaxially sleeved on a joint point of cables, the elastic insert which prevents the cables from damage is coaxially fixed in the outer sleeve, and the annular grooves are respectively arranged at the axial two ends and the middle of the outer sleeve, wherein the outer sleeve is made of aluminum alloy material. The cable joint point sealing device is simple in structure, reasonable in design, convenient to install and good in sealing effect, can effectively prevent impurities as rainwater and dusts from entering the sleeve, prevents overheat, and prolongs service life of equipment.
Description
Technical field
The utility model belongs to the electric power facility apparatus field, and especially a kind of cable is taken fire point closing device.
Background technology
Cable termination is equipped with the wiring sleeve usually, and present to take fire point sleeve barrel structure fairly simple, has gap between sleeve and cable, in long-time the use, in environment, easily cause cable overheated especially out of doors, acceleration equipment is aging, even causes sleeve loosening, has potential safety hazard.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of cable simple in structure, reasonable in design, easy for installation, that sealing effect is good to take fire point closing device.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of cable is taken fire point closing device, comprise outer sleeve, elastic insert and annular groove, the outer sleeve coaxial package is at the cable link position, coaxially be fixed with the elastic insert that one deck prevents from damaging cable in outer sleeve, outer sleeve adopts aluminum alloy materials to make, and it is characterized in that: the axial two ends of described outer sleeve all are shaped with an annular groove; The middle part of described sleeve is shaped with an annular groove.
And a plurality of annular grooves are suppressed at described outer sleeve middle part uniformly at intervals.
And described annular groove cross section is coaxial annular or concentric regular hexagon.
Advantage of the present utility model and good effect are:
Of the present utility model simple in structure, reasonable in design, easy for installation, sealing effect is good, effectively prevents that the impurity such as rainwater, dust from entering in the wiring sleeve, it is overheated to prevent, the useful life of extension device.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that A-A in Fig. 1 is to schematic cross-section;
The A-A that Fig. 3 is another embodiment of the utility model is to schematic cross-section.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
A kind of cable is taken fire point closing device, comprise outer sleeve 1, elastic insert 4 and annular groove 2, as accompanying drawing 1 to as shown in accompanying drawing 2, the outer sleeve coaxial package is at cable 3 link positions, coaxially be fixed with the elastic insert that one deck prevents from damaging cable in outer sleeve, outer sleeve adopts the good aluminum alloy materials of ductility to make.
Innovative point of the present utility model is:
The axial two ends of described outer sleeve all are shaped with an annular groove, effectively compress and cable between gap, prevent that rainwater etc. from entering in the wiring sleeve.
In order further to prevent there is gap between wiring sleeve and cable, the middle part of described sleeve also is shaped with an annular groove, according to concrete sealing length, can suppress a plurality of annular grooves at interval, outer sleeve middle part.
Shown in the present embodiment accompanying drawing, the annular groove cross section is coaxial annular, or concentric regular hexagon.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
