technical field

The utility model relates to a fast wiring technology for power supply cables of a medium and low voltage distribution network, in particular to an emergency connection device for cables.

Background technique

With the continuous improvement of the utilization rate of cables in the urban distribution network and the complexity of the urban power grid, the probability of external breakage and other faults of the cables increases. During emergency repairs, it is more and more difficult to move and connect cables located at high altitude or underground. It is very necessary to reduce the difficulty of connection and restore the power supply quickly. At present, the conventional cable splicing technology is to peel off the outer sheath of the cable, and then peel the single-strand cables and tighten them with the single wires of the corresponding lines one by one, and then wrap them with insulating tape. It is used for emergency circuit repairs, especially Although the emergency repair of high-altitude or underground lines can meet the requirements of restoring power supply, it takes a long time and there is room for further improvement. Some wire connectors are also used, but the wire connectors available on the market are mainly used for household use. When they are used in distribution network cables, because they do not have the function of preventing disconnection, it is very easy for the wires to fall off twice in the longitudinal direction, forming a second power grid. secondary failure.

To achieve the above object, the utility model adopts the following technical solutions:

A cable emergency connection device, comprising: a main body, a conductive sheet and a locking block, the main body as a whole is a one-time molded insulating shell structure with an upper opening, and two ends in the longitudinal direction are symmetrically provided with through holes for the wires to pass through, and each The outer orifice of each through hole is provided with a solid-integrated wire guide sleeve, the wire guide sleeve is provided with a threaded wire fixing sleeve, the middle of the bottom wall of the main body is provided with a groove in the length direction, and the groove is arranged in the groove. A conductive sheet is provided. The conductive sheet is a concave-convex conductive metal plate as a whole. The two ends of the conductive sheet are respectively located under the inner holes of the through holes at both ends of the body. The body above the slot is provided with insulating locking blocks. The locking block is a rectangular block structure as a whole, and its width is consistent with the width of the upper opening of the body. The upper end surface of the locking block is connected to the groove of the bottom wall of the body through screws The bottom walls on both sides are fixedly connected, and the lower end face of the locking block is provided with a boss corresponding to the accommodating groove of the conductive sheet.

The length of the locking block is equal to half of the length of the upper opening of the main body, and guide blocks are also provided on both sides of the length direction of the locking block; the two side walls of the main body are provided with corresponding to each locking block. The guide groove that the guide block is matched with.

The two ends of the conductive sheet are respectively fixed to the bottom surfaces of the grooves at both ends of the groove of the main body through countersunk screws.

The beneficial effects of the utility model are as follows: the utility model has a simple structure, and by designing a concave-convex pressing type fixed wiring structure, the connection of the single-strand wire of the cable can be completed in a relatively short time, and the utility model has the function of preventing the longitudinal slippage of the wire, and the wiring is fast and convenient. It is firm and suitable for emergency repair of cables in medium and low voltage distribution networks.

Detailed ways

The present utility model will be further described in detail below in conjunction with the accompanying drawings.

A cable emergency connection device, comprising: a main body 1, a conductive sheet 2 and a locking block 3, the main body 1 is a one-time molded insulating shell structure with an upper opening as a whole, and the two ends of the longitudinal direction are symmetrically arranged with wires for passing through. Through holes 101, the outer orifice of each through hole is provided with a solid-integrated wire guide sleeve 4, the wire guide sleeve 4 is provided with a threaded wire fixing sleeve 5, and the middle of the bottom wall of the body 1 is in the length direction. A groove 102 is provided on the groove 102, and a conductive sheet 2 is arranged in the groove 102. The conductive sheet 2 is a concave-convex conductive metal plate as a whole. The upper end surface of the conductive sheet 2 is symmetrically provided with accommodating grooves 201, and an insulating locking block 3 is arranged in the body 1 above each accommodating groove 201. The locking block 3 is a rectangular block structure as a whole, and its width is The width of the upper opening of the main body 1 is the same, the upper end surface of the locking block 3 is respectively fixed with the bottom walls on both sides of the groove 102 of the bottom wall of the main body 1 by screws, and the lower end surface of the locking block 3 is provided with the conductive sheet accommodating groove 201.
