Utility model content
When being attached inside ring main unit with ring main unit inner part for cable in practice, cable, especially its
Larger bending easily occurs for the cable of position contacted with ring main unit inner wall, and cable abrasion, bending is caused even to be broken, influences ring
This problem of the normal work of net cabinet, the purpose of this utility model is that proposing a kind of ring main unit cable protecting device, specifically
Scheme is as follows：
A kind of ring main unit cable protecting device including cabinet, offers the connector that current supply cable passes through on the cabinet,
The protective device is set to the cabinet inner wall at the connector, and the protective device includes having the first arc opening
The first connector, have the second arc opening the second connector and for opening and closing first connector, the second connector
Opening and closing element, first arc opening is parallel with the axis of the connector with the axis of second arc opening；
When the opening and closing element is closed fixed first connector with second connector, first arc opening with
The second arc opening cooperation encloses out a circular groove being adapted to cable profile, the axis of the axis of the circular groove and the connector
Line is consistent.
Through the above technical solutions, cable is pierced into inside cabinet, cable be located at the first connector and the second connector it
Between, opening and closing element work is closed the first connector and the second connector, the first arc opening and the second arc opening are enclosed at this time
Circular groove is adapted to cable profile, fixes the first connector and the second connector, and cable is located in cable inside cabinet with cabinet
Junction is fixed, and avoids cable that larger bending occurs at this, and cable is not easy to wear, bending is even broken, and protects cable, and then
Protect the normal work of ring main unit.
Further, cabinet inner wall setting is there are two fixed block, the connector be located at two fixed blocks it
Between, a lifting lug is fixedly connected on two fixed blocks, being connected with one between two lifting lugs is enclosed in described first
The fixed plate of connector periphery, the fixed plate are adapted to the periphery of first connector.
Through the above technical solutions, lifting lug and fixed plate are fixedly connected together by fixed block with cabinet, stable connection is hung
