Abstract
The utility model relates to an outer joint leakproof structure of a submersible electric pump cable. The outer joint leakproof structure comprises an outer heat-shrinkable casing tube, and tin sealing layers. The outer heat-shrinkable casing tube is wrapped on a peeled copper wire portion on an outer wiring end of a cable and an isolated outer wall. The tin sealing layers are disposed among the peeled copper wires and among the copper wires and the isolated outer wall. The outer joint leakproof structure is novel in structure, convenient in processing, low in production cost, and good in sealing effect. The outer joint leakproof structure effectively isolates moisture or moist air, solves problems that conventional seal is easy to lose efficacy, and increases service life of diving electric devices.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction, particularly a kind of submersible electric pump cable line coupling hermetically-sealed construction.
Background technology
The submersible electric pump cable water-tight is directly to affect submersible motor reliability key factor, and reprocessing has 70% all to be because the cable water inlet causes coil to make moist until burn in the electric pump.The external head end of traditional submersible pump cable easy loose or dislocation after long-term use the, and the copper cash gap that strip off connects easily intakes, and causes seal failure, and causes the water inlet of cable place is so that motor entering water, burn.
Summary of the invention
The purpose of this utility model is to overcome the problem that prior art exists, and has proposed a kind of submersible electric pump cable line coupling hermetically-sealed construction of simple in structure, good sealing effect.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of submersible electric pump cable line coupling hermetically-sealed construction, it is characterized in that comprising outer heat-shrinkable T bush and tin seal, outer heat-shrinkable T bush is wrapped on the strip off copper wire part and insulation outer wall of the external head end of cable, between the strip off copper wire of the external head end of cable, be provided with the tin seal between copper wire and the insulation outer wall.
Compared with prior art, the beneficial effect that the utility model reaches is: the external head end of cable is provided with outer heat-shrinkable T bush, when preventing that effectively long-term use from coming off, can effectively prevent the gap seepage of the external head end of cable junction; The external head end of cable is provided with the tin seal, effectively between the strip off copper wire, the gap seepage between copper wire and the cable insulation outer wall.
The utility model is provided with the slip-off preventing sealing at the external head end of cable, its novel structure, easy to process, production cost is low, cable connection structure is stable, good sealing effect, can effectively completely cut off moisture or humid air, solve that conventional seals comes off easily, the problem of leakage loss, increase the useful life of diving electric device.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: cable 1, outer heat-shrinkable T bush 2, copper wire 3, tin seal 4.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Shown in the accompanying drawing 1, a kind of submersible electric pump cable line coupling hermetically-sealed construction comprises outer heat-shrinkable T bush 2 and tin seal 4, outer heat-shrinkable T bush 2 is wrapped on strip off copper wire 3 parts and insulation outer wall of cable 1 external head end, between the strip off copper wire of the external head end of cable, be provided with the tin seal between copper wire and the insulation outer wall.
