Abstract
The utility model relates to a connector protecting device and especially relates to a cable connector protecting device. The protecting device comprises a fine copper pullover (3) pressing a bare cold wire (4) and a heating wire (5) together, a sealing inner protective layer (1) which is produced by polyvinyl chloride plastics and which is wrapped round the connector, and an outer protective layer (2) which is produced by polyvinyl chloride plastics and which is wrapped round the inner protective layer (1). The inner protective layer (1) and the outer protective layer (2) are hermetically connected with the cold wire (4) and the heating wire (5). By the two disposed protective layers, the protecting device is made to achieve characteristics of good sealing performance and strong waterproof capability. And a cable can be supplied with electricity when placed in water. Therefore, the cable connector protecting device not only resolves a waterproof problem, but also has a real insulation effect.
Description
Technical field
The utility model relates to a kind of connector protection device, especially relates to a kind of Geothermal electric cable connector protection device.
Background technology
Cable joint partly is part the weakest in the whole cable line, usually causes the interruption of whole circuit because of the fracture of blank area.Traditional joint style generally is to insulate to finish by artificial crimping and heat-shrink tube to cold and hot line.Heat-shrink tube be by to can dwindling behind its surface heating, thus to the processing of its cold and hot line insulation, many because of level, pipe diameter size is different, so that water resistance is bad, easily infiltration, meeting produce the globule after conduction time was long in heat-shrink tube, produced easily potential safety hazard.
The utility model content
For the defective that exists in the prior art, technical problem to be solved in the utility model provides the good cable joint protector of a kind of security performance.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of cable joint protector, comprise that the fine copper that the cold wire that will expose and line with heating function be crimped on together is pullover, be provided with the sealing inner protective layer of being made by igelite in the joint outside, also be provided with the external protection of being made by igelite in the outside of described inner protective layer; Described inner protective layer and external protection and cold wire and line with heating function are tightly connected.
Aforesaid cable joint protector, wherein, inner protective layer and external protection seamless link.
Aforesaid cable joint protector wherein, is provided with some holes at external protection.
Cable joint protector described in the utility model, by two-layer protective layer is set, so that the protective device good airproof performance, water proofing property is strong, drops in the water and still can switch on.Both solve waterproof problem, played again real insulating effect.
Description of drawings
Fig. 1 is vertical sectional drawing of cable joint protector in the embodiment.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
As shown in Figure 1; cable joint protector in the present embodiment; comprise that the cold wire 4 that will expose and line with heating function 5 are crimped on fine copper pullover 3 together; be provided with the sealing inner protective layer 1 of being made by igelite in the joint outside, also be provided with the external protection 2 of being made by igelite in the outside of inner protective layer 1.Described inner protective layer 1 and external protection 2 are tightly connected with cold wire 4 and line with heating function 5.Inner protective layer 1 and external protection 2 seamless links, the centre does not have the slit.On external protection 2, also be provided with several holes 6.The effect of supporting the inside line is played in hole 6 when injection moulding.
The advantage of cable joint protector is that water proofing property is strong in the utility model, drops in the water and still can switch on, and has both solved waterproof problem, has played again real insulating effect.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technology thereof, then the utility model also is intended to comprise these changes and modification interior.
