Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1 to 2, the present invention discloses a cable connection device for a submersible motor, which includes an upper cover 10, a base plate 30, and a spring 20. A first mounting hole is formed in the upper cover 10, a second mounting hole is formed in the bottom plate 30, and the cable 90 is inserted into the first mounting hole and the second mounting hole. The upper cover 10 and the cable are fixed by the first pressing piece 60; the base plate 30 and the cable are fixed by the second pressing member 70.

One end of the spring 20 is fixed to the upper cover 10, and the other end of the spring 20 is fixed to the base plate 30. In this manner, the upper cover 10 and the bottom plate 30 can be elastically moved closer to or farther from each other. A receiving compartment for receiving the bent cable is provided between the upper cover 10 and the bottom plate 30. As shown in fig. 1, the cable has a bent portion 91, and the bent portion 91 is disposed in the accommodating chamber, so that the bent portion 91 in the accommodating chamber can be slightly straightened when the upper cover 10 is moved upward relative to the bottom plate 30 due to the pulling of the cable. When the cable pulling stops, the upper cover 10 is close to the base under the action of the spring 20, so that the bending part 91 of the cable 90 is folded. Therefore, the cooperation of the spring 20 and the bent portion 91 of the cable 90, when the cable 90 is pulled, the upper cover 10 floats together, but the bottom plate 30 does not move, and the sealing performance of the cable and the bottom plate 30 is ensured. The spring 20 has a plurality of springs 20, and the plurality of springs 20 are arranged around the cable. The arrangement of a plurality of springs 20 can enhance the elastic potential energy, and the arrangement of a plurality of springs 20 around the cable can improve the stability of the whole device.

Referring to fig. 1, a first limiting plate 40 is vertically arranged on the lower side of the upper cover 10, a second limiting plate 50 is vertically arranged on the upper side of the bottom plate 30, the first limiting plate 40 and the second limiting plate 50 are arranged in parallel, the first limiting plate 40 is located on the inner side of the second limiting plate 50, a first hook portion 41 is arranged on the first limiting plate 40, and a second hook portion 51 is arranged on the second limiting plate 50; the vertical downward projection of the first hook 41 covers the second hook 51. Due to the first hook part 41 and the second hook part 51, the maximum distance between the upper cover 10 and the bottom plate 30 can be controlled, and thus, the excessive extension of the spring 20 is prevented, and the plastic deformation is avoided. The first limiting plate 40 and the second limiting plate 50 are both circular. The circular limiting plate is good in symmetry and more stable in structure.

Referring to fig. 2, a threaded hole 11 is formed in the upper surface of the upper cover 10, a tapered hole 12 is formed in the lower side of the threaded hole 11, the lower end of the first pressing member 60 is disposed in the threaded hole 11 and the tapered hole 12, a thread matched with the threaded hole 11 is disposed at the lower end of the first pressing member 60, the cable is disposed in the first pressing member 60, a protruding block 62 is disposed on the first pressing member, and the protruding block 62 abuts against the inner wall of the tapered hole 12. Since the protrusion 62 presses against the inner wall of the tapered hole 12 during the tightening process of the pressing member and the threaded hole 11, the tapered hole 12 applies an opposite force to the protrusion 62 during the tightening process, which causes the lower end of the pressing member to inwardly tighten the pressing cable. The end of the pressing member having the protrusion 62 is made of an elastic material, such as rubber.

The first pressing member 60 is provided with a cap 61. The cap 61 facilitates locking the pressing member with the upper lid 10. The second pressing member 70 has a structure similar to that of the first pressing member 60, and the second pressing member 70, the base, and the cable are fixed to each other. A mounting seat 31 connected to a motor is fixedly provided under the bottom plate 30. Of course, the second pressing member 70 may be provided on the mount 31. The mounting seat 31 is for easy mounting on the motor. Thereafter, the mounting seat 31 is fixed to the motor, and the cable is inserted into the motor and sealed by conventional potting or the like, which will not be described in detail herein.

One end of the spring 20 is fixed to the upper cover 10 by the first locker 80. The other end of the spring 20 is fixed to the base by a second locking member 81. The first and

second locking members

80 and 81 may be bolts.

The spring 20 is arranged between the upper cover 10 and the bottom plate 30, and the bottom plate 30 is fixed with the motor. And because the cable is provided with flexion 91 between upper cover 10 and bottom plate 30, like this, when the cable receives to pull, under the effect of spring 20, upper cover 10 can move relative to bottom plate 30, but bottom plate 30 and the fixed cable 90 of bottom plate 30 department can be fixed motionless, so, can solve the cable and pull the problem of separating the line, the cable then is difficult for being destroyed with the motor leakproofness.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
