Abstract
The utility model belongs to the technical field of submersible motors and particularly relates to a hermetically-sealed structure for a cable lead-wire of a submersible motor. A mounting blind hole of a cable sheath is disposed on a motor shell. The inner cylindrical surface of the upper portion of the blind hole is provided with threads. A wiring post hole is disposed at the bottom of the blind hole. A wiring post arranged on the cable sheath penetrates through the wiring post hole ad extends into an inner cavity of the motor shell. A wire pressing nut is disposed on a cable arranged on the cable sheath, connected with the threads on the mounting blind hole of the cable sheath in threaded mode and tightly compresses the cable. A washer is disposed between the upper plane of the cable sheath and the wire pressing nut. A compressing piece is disposed on the wire pressing nut and fixedly connected with the motor shell. The cable sheath are deformed and sealed through tight compression of the wire pressing nut so that water is prevented from entering the bottom surface of the cable sheath and contacting with the charged wiring post. The compression piece is tightly screwed by using screws so as to compressing the wire pressing nut. Consequently, sealing failure caused by looseness of the wire pressing nut is prevented.
Description
Technical field:
The utility model belongs to the submersible motor technical field, refers in particular to a kind of diving generator cable lead-out wire hermetically-sealed construction.
Background technology:
When submersible motor is worked under water, need anti-sealing to get into motor and cause that burn-down of electric motor or electric shock incident take place from the motor cable lead-out wire.
Summary of the invention:
The purpose of the utility model provides a kind of diving generator cable lead-out wire hermetically-sealed construction of simple in structure, easy to use, good sealing effect.
The utility model is achieved in that
Diving generator cable lead-out wire hermetically-sealed construction; Motor housing is provided with the cable cover(ing) installing blind; The inner cylinder face on blind hole top is provided with screw thread, and the bottom of blind hole is provided with the binding post hole, and the binding post on the cable cover(ing) passes the binding post hole and stretches into the motor housing inner chamber; The line ball nut sleeve is contained on the cable on cable cover(ing) top and is spirally connected and compresses with screw thread on the cable cover(ing) installing blind; Between plane on the cable cover(ing) and line ball nut, be provided with packing ring, the line ball nut is provided with compressing member, described compressing member be connected on the motor housing.
Above-mentioned compressing member passes through screw on motor housing.
Above-mentioned compressing member is the pressing plate that a pressing plate or a side are provided with handle.
The utility model is compared the outstanding advantage of prior art:
The cable cover(ing) of the utility model compresses deformable seal through the line ball nut; Stop water to get into the cable cover(ing) bottom surface; Thereby the binding post of contact electrification, line ball nut adopt sealing thread to stop water to get into the cable cover(ing) bottom surface from screw thread, the line ball nut through compressing member with the urgent line ball nut of pushing down of screw; Thereby stop because of the line ball nut thread becomes flexible and cause seal failure, simple in structure, easy to use, good sealing effect.
Description of drawings:
Fig. 1 is the cutaway view of the utility model.
Embodiment:
With specific embodiment the utility model is further described below, referring to Fig. 1:
Diving generator cable lead-out wire hermetically-sealed construction; Motor housing 7 is provided with the cable cover(ing) installing blind; The inner cylinder face on blind hole top is provided with screw thread, and the bottom of blind hole is provided with the terminal hole, and the binding post 1 on the cable cover(ing) 2 passes the binding post hole and stretches into motor housing 7 inner chambers; Line ball nut 3 is sleeved on the cable on cable cover(ing) 2 tops and is spirally connected and compresses with screw thread on the cable cover(ing) installing blind; Between plane on the cable cover(ing) 2 and line ball nut 3, be provided with packing ring 6, line ball nut 3 is provided with compressing member 4, described compressing member 4 be connected on the motor housing 7.Cable cover(ing) 2 compresses deformable seal through line ball nut 3, stops water to get into cable cover(ing) 2 bottom surfaces, thus the binding post of contact electrification 1, and line ball nut 3 adopts sealing thread to stop water to get into cable cover(ing) 2 bottom surfaces from screw thread.
Above-mentioned compressing member 4 is the pressing plate that a pressing plate or a side are provided with handle, and handled pressing plate or pressing plate are fixed on the motor housing 7 through screw 5.Compressing member 4 prevents to cause seal failure because of the line ball nut thread becomes flexible.
The foregoing description is merely one of preferred embodiment of the utility model; It is not the practical range that limits the utility model with this; So: the equivalence that all shapes according to the utility model, structure, principle are done changes, and all should be covered by within the protection range of the utility model.
