Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed implementation and the specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.
The embodiment provides a power cable connection device of 1kV and below, belongs to the technical field of railway corollary equipment, and comprises a wire core connector I1 and a wire core connector II 2, wherein one ends of the wire core connector I1 and the wire core connector II 2 are in matched butt joint, the other ends of the wire core connector I1 and the wire core connector II 2 are respectively provided with a locking joint I3 and a locking joint II 4, and sealing rings 5 are arranged in the wire core connector I1 and the wire core connector II 2; the other ends of the first wire core connector 1 and the second wire core connector 2 are respectively provided with a first corrugated pipe 6 and a second corrugated pipe 7, and one ends of the first corrugated pipe 6 and the second corrugated pipe 7 respectively extend into the first wire core connector 1 and the second wire core connector 2 through a first locking joint 3 and a second locking joint 4 and abut against a sealing ring 5 of the first wire core connector 1 and the second wire core connector 2; and the end surfaces of the other ends of the wire core connector I1 and the wire core connector II 2 are respectively provided with a universal chuck 9.
It should be noted that, the seal ring seals the end portions of the first corrugated pipe and the second corrugated pipe and the end portions of the first core connector and the second core connector well, and forms a good sealing effect on a gap between the first corrugated pipe and the second corrugated pipe and the end portions of the first core connector and the second core connector to prevent external moisture from entering, so as to solve the problem that the sealing performance between the end portions of the first corrugated pipe and the second core connector is poor.
In this embodiment, the ends of the first corrugated pipe 6 and the second corrugated pipe 7 extending into the first core connector 1 and the second core connector 2 are respectively sleeved with a hoop member 8, the inner periphery of the hoop member 8 is provided with a groove matched with the corrugated bulges on the outer surface of the first corrugated pipe 6 or the second corrugated pipe 7, and the groove and the corrugated bulges are detachably clamped; when the first corrugated pipe 6 and the second corrugated pipe 7 extend into the first core connector 1 and the second core connector 2, the outer periphery of the connected hoop part 8 is tightly abutted to the inner wall of the first core connector 1 or the second core connector 2. The first corrugated pipe and the second corrugated pipe can be well fixed in the first core connector and the second core connector through the clamp piece, so that the first corrugated pipe and the second corrugated pipe can always tightly abut against the sealing rings of the first core connector and the second core connector, the waterproof function of the connecting device is guaranteed, and the anti-impact performance of the connecting device is improved.
In this embodiment, the first bellows 6 and the second bellows 7 are made of stainless steel. Bellows one and bellows two are carried out whole processing and are made through the mould, compare ordinary coiling formula iron sheet protection hose, and intensity is higher, and the reliability is better.
