Abstract

The utility model discloses a sealing device for a cable head of a submersible motor, which is composed of a metal motor head (4), a cable (7), a wire code (5) and the like, and is characterized in that the wire code (5) clamps and presses the wire clip (6 ) and a cylindrical rubber sealing ring (3), and the outlet abutment (9) at the lower end supports the hard circular washer (2). The utility model has the advantages of reasonable structure, good sealing performance, convenient production and operation, low cost and easy popularization and implementation.

Description

Diving generator cable the end of a thread sealing device

Technical field

The utility model discloses a kind of diving generator cable the end of a thread sealing device, belongs to industrial electronic product design category.

Background technology

That the outlet of its cable of now disclosed submersible motor mostly is to adopt rubber parts to add to seal glue is bonding, and the upper end compresses it with nut and realizes.The problem of this structure maximum is that tightness is not high, easily cause seepage, particularly sealing property being required higher deep-well submersible motor, is can't be guaranteed, often because of the seepage of cable outlet water is entered into cause in the motor coil motor stator prick between the coil short circuit burn loom.

The purpose of this utility model just provides a kind ofly can satisfy that high pressure conditions also can be dived under water at deep-well, satisfy the cable clamp sealing device of its sealing property on the submersible electric machine with oil.

Summary of the invention

The utility model diving generator cable the end of a thread sealing device is achieved in that by metal motor head, cable, line code etc. and constitutes, three garden lines are arranged in the cable, the vertical direction of garden shape packing ring and garden column rubber seal is provided with three Dao Yuan holes, three wires were gone here and there the small garden hole in garden shape packing ring and the garden column rubber seal respectively, and the aperture of small garden hole and electric wire external diameter are to be complementary tightly to go into.The outlet of cable on the metal motor head be post chamber, garden shape, the lower end is provided with a base station, play the shape packing ring effect of support foot hard garden, wire clamp is identical and to be that symmetrical plastics side is nonmetal make by two plate shapes sizes, be to present the little big down middle hole identical that be provided with simultaneously with the cable cross section, it is similar to the last end section of wire clamp that the centre of line code is set as the ellipticity opening, and two ends, the left and right sides are to have garden shape screw hole.

When line code is tightened up, line code with wire clamp toward pressing down, the lower end of wire clamp is pushed garden column rubber seal again, the garden column rubber seal of this moment will be subjected to the depression effect, force rubber seal to expand to the left and right, make its packing go out the edge and the electric wire of cable aperture, reach the purpose of high-seal.

The utility model diving generator cable the end of a thread sealing device, have rational in infrastructure, good seal performance, easy for installation, cost is low, be easy to advantages such as promotion and implementation.

Description of drawings

Describe in detail below in conjunction with accompanying drawing:

Accompanying drawing 1 is a metal motor head schematic diagram;

Accompanying drawing 2 is A-A partial cutaway diagrammatic sketch of accompanying drawing 1;

Accompanying drawing 3 is garden column rubber seal schematic diagrames;

Accompanying drawing 4 is wire clamp schematic diagrames;

Accompanying drawing 5 is garden shape packing ring schematic diagrames;

Accompanying drawing 6 is line code schematic diagrames.

Embodiment

In each accompanying drawing, three garden electric wires (8) are arranged in the cable (7), three wires (8) were gone here and there garden column rubber seal (3) respectively, three Dao Yuan holes (11) enter into motor cavity (10) in the garden shape packing ring (2), use insulation cotton varnished sleeve (1) with its protection afterwards again, cover is loaded onto two wire clamps (6) in the line code (5), when tightening up line code (5) with bolt (15), line code (5) is being oppressed garden column rubber seal (3) toward pressing down with wire clamp (6) and lower end (14), the packing ring (2) of bottom is withstood by cable outlet base station (9) again, because of forcing rubber seal (3), last depression effect can only expand toward about, further with real the shutting of cable exit week banding, three wires (8) are also by bigger real the shutting of rubber column envelope of retractility simultaneously, reach high-seal, gas, water can't seepage be entered.

Claims

1. A sealing device for the cable end of a submersible motor, which is composed of a metal motor head (4), a cable (7), and a wire code (5), and is characterized in that the wire code (5) clamps and presses the wire clip (6), Garden columnar rubber sealing ring (3), garden shape washer (2), the lower end is the cable outlet abutment (9).

2. A kind of submersible motor cable head sealing device according to claim 1, characterized in that there are three garden holes (11) in the vertical direction of the garden gasket (2) and the garden columnar rubber sealing ring (3), and the cable ( 8) string into the machine from three garden holes (11).

3. A sealing device for cable ends of submersible motors according to claims 1 and 2, characterized in that the clamp (6) is composed of two pieces, which are small at the top and large at the bottom, with an opening similar to the cross section of the cable. And is symmetrical.
