Abstract
The utility model relates to an inner joint leakproof structure of a submersible electric pump cable. The inner joint leakproof structure comprises a wiring tube, an inner heat-shrinkable casing tube, and an insulated rubber tape. A cable wiring end and a wired end are connected in the wiring tube. The inner heat-shrinkable casing tube is disposed outside the wiring tube. An outer wall of the inner heat-shrinkable casing tube, an outer wall of a joint position of the inner heat-shrinkable casing tube and the cable wiring end, and an outer wall of a joint position of the inner heat-shrinkable casing tube and the cable wired end are all wrapped with insulated rubber tapes. The inner joint leakproof structure is novel in structure, convenient in processing, low in production cost, and good in sealing effect. The inner 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 nipple 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.Traditional submersible pump cable incoming seal, it is the terminal box place at immersible pump, by regulating hold-down bolt, carry out first compression with rubber ring, thereby come cable is sealed, its at water pump in transportation, installation, use procedure, the water pump cable is subject to the impact of external pull, easily produces and becomes flexible, and the sealing of cable nipple place was easily lost efficacy, and cause cable adapter place water inlet, 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 nipple 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 nipple hermetically-sealed construction, it is characterized in that: comprise wire barrel, interior heat-shrinkable T bush and insulating tape, cable termination be connected in wire barrel by terminals, wire barrel is provided with interior heat-shrinkable T bush outward, and interior heat-shrinkable T bush outer wall, interior heat-shrinkable T bush and cable termination socket place outer wall, interior heat-shrinkable T bush and cable all are coated with insulating tape on the terminals socket place outer wall.
Compared with prior art, the beneficial effect that the utility model reaches is: cable termination with docked by terminals after the socket wire barrel, on the wire barrel in the socket behind the heat-shrinkable T bush by the insulating tape sealed package, prevent long-term use pull loosening in, can effectively prevent the gap seepage of terminal box inner cable docking junction.
The utility model arranges the loosening hermetically-sealed construction of anti-slip at cable termination, and its novel structure is easy to process, production cost is low, and good sealing effect can effectively completely cut off moisture or humid air, solve tradition and pulled the problem that pine send sealing easily to lose efficacy, increased the useful life of diving electric device.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: cable termination 1, cable be by terminals 2, wire barrel 3, interior heat-shrinkable T bush 4, insulating tape 5.
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 nipple hermetically-sealed construction comprises wire barrel 3, interior heat-shrinkable T bush 4 and insulating tape 5, cable termination 1 with by terminals 2 in 3 interior connections of wire barrel, be provided with interior heat-shrinkable T bush 4 outside the wire barrel 3, interior heat-shrinkable T bush outer wall, interior heat-shrinkable T bush and cable termination socket place outer wall, interior heat-shrinkable T bush and cable all are coated with insulating tape 5 on the terminals socket place outer wall.
