Abstract
The utility model discloses a sealing device for the cable lead-out wire of a submersible sewage pump. The sealing device comprises the lead-out wire cable, wherein an integrally-connected insulating sleeve is arranged outside the cable lead-out wire. The sealing device further comprises an end cover, and a gland fixedly installed on the end cover, wherein a step hole is formed in the end cover, the upper end and the lower end of the gland are provided with a cylindrical hole and a conical hole which are connected respectively, an annular step is arranged on the outer wall of the insulating sleeve, and the upper end of the annular step is a conical surface; and the cable lead-out wire and the insulating sleeve sequentially penetrate through the step hole, the conical hole and the cylindrical hole from bottom to top and extend out, the lower end of the annular step is pressed on the step surface of the step hole, and the upper end of the annular step is jacked against the inner wall of the conical hole. The sealing device disclosed by the utility model is simple in structure, low in production cost, high in assembly efficiency, and free from the phenomenon of water seepage in a motor junction box, thus improving the sealing performance of the cable of the submersible sewage pump; and the insulating sleeve is made from rubber, thus effective improving the wear resistance of the cable, and greatly improving the stretching capacity of the cable.
Description
Technical field
The utility model relates to the technical field of sealing technology of power cable and the control cables lead-out wire of submersible sewage pump motor, specifically a kind of submersible sewage pump cable pigtail sealing device.
Background technology
The cable seal structure of the submersible sewage pump motor that uses in prior art, be rubbery outer cover and electrical cables separate structure, and namely rubber layer directly is enclosed within on cable when mounted,, for the protection of cable, prevents the wearing and tearing at cable and terminal box bucket edge.Sealing between cable and end cap mainly compresses the cup packing circle with the terminal box bucket and realizes sealing.This structure mainly contains following shortcoming, in the process of long-time operation under water, owing to ceaselessly rubbing and moving, there is again the cup packing circle aging, easily produce gap between cable and cup packing circle, cause water to leak into motor internal, and then cause the damage of water pump integral body.Existing structure sealing structure part kind is more, and production cost is also higher, and efficiency of assembling is lower.In addition, the hermetically-sealed construction of existing structure is divided into two parts sealing, is movable sealing between cable and cup packing circle, generally all with a small amount of or micro-leakage.
The utility model content
The purpose of this utility model is to provide a kind of submersible sewage pump cable pigtail sealing device of favorable sealing property, belongs to static seal, changes original two seals into place's static seal, to reduce the chance of water to the terminal box seepage.
The technical solution of the utility model is as follows:
A kind of submersible sewage pump cable pigtail sealing device, include cable pigtail, it is characterized in that: the outside of described cable pigtail has the insulating case that one connects, include end cap and the gland that is fixedly mounted on end cap, described end cap is provided with stepped hole, upper and lower end on gland is respectively equipped with cylindrical hole and the bellmouth that connects, and has ring-shaped step on the outer wall of described insulating case, and the upper end of described ring-shaped step is taper surface; Described cable pigtail and insulating case pass successively described stepped hole, bellmouth and cylindrical hole from bottom to top and extend, and the lower side pressure of described ring-shaped step is put on the step surface of stepped hole, and the upper end of ring-shaped step leans on the inwall of bellmouth.
Described submersible sewage pump cable pigtail sealing device is characterized in that: the material of described insulating case is rubber.
Described submersible sewage pump cable pigtail sealing device is characterized in that: the angle of the taper surface of described ring-shaped step upper end and the inwall of bellmouth and horizontal direction is 45 °.
The beneficial effects of the utility model:
Cable pigtail of the present utility model is connected connection with the exterior insulation cover, not there will be water to infiltrate the phenomenon of connection box for motor, change original two seals into place's static seal, not only improved the sealing property of submersible sewage pump motor cable, the part kind also reduces thereupon simultaneously, make the hermetically-sealed construction after improving simpler, reduced production cost, improved efficiency of assembling; The material selection rubber of insulating case, effectively raise the wear resistance of cable, also significantly promoted the stretch capability of cable.

Fig. 2 is the structural representation of the utility model gland.
Embodiment
Referring to Fig. 1,2, a kind of submersible sewage pump cable pigtail sealing device, include cable pigtail 1, the outside of cable pigtail 1 has the insulating case 2 that one connects, include end cap 4 and the gland 3 that is fixedly mounted on end cap 4, end cap 4 is provided with stepped hole, and the upper and lower end on gland 3 is respectively equipped with cylindrical hole 6 and the bellmouth 7 that connects, have ring-shaped step 5 on the outer wall of insulating case 2, the upper end of ring-shaped step 5 is taper surface; Cable pigtail 1 and insulating case 2 pass successively stepped hole, bellmouth 7 and cylindrical hole 6 from bottom to top and extend, and the lower side pressure of ring-shaped step 5 is put on the step surface of stepped hole, and the upper end of ring-shaped step 5 leans on the inwall of bellmouth 7.
In the utility model, the material of insulating case 2 is rubber; The angle of the taper surface of ring-shaped step 5 upper ends and the inwall of bellmouth 7 and horizontal direction is 45 °, and sealingly secure is reliable.
Claims (3)
1. submersible sewage pump cable pigtail sealing device, include cable pigtail, it is characterized in that: the outside of described cable pigtail has the insulating case that one connects, include end cap and the gland that is fixedly mounted on end cap, described end cap is provided with stepped hole, upper and lower end on gland is respectively equipped with cylindrical hole and the bellmouth that connects, and has ring-shaped step on the outer wall of described insulating case, and the upper end of described ring-shaped step is taper surface; Described cable pigtail and insulating case pass successively described stepped hole, bellmouth and cylindrical hole from bottom to top and extend, and the lower side pressure of described ring-shaped step is put on the step surface of stepped hole, and the upper end of ring-shaped step leans on the inwall of bellmouth.
