Detailed Description

The present utility model will be described in further detail with reference to examples and drawings, but embodiments of the present utility model are not limited thereto.

Example 1

As shown in fig. 1 to 2, the present utility model aims to: in order to solve the problems, the cable switching device is easy to assemble and disassemble and can prevent manual misconnection.

The utility model is realized by the following technical scheme: an anti-misplug cable transit comprises an insulating cavity 1, a 2-core connector socket (i.e. the connector socket 2), a first conductive copper bar (i.e. the first conductive piece 41), a second conductive copper bar (i.e. the second conductive piece 42) and an insulating cover plate 3. The front end of the insulating cavity 1 is provided with a 2-core connector socket for being inserted with cables of other electrical equipment, and the rear end of the insulating cavity 1 is fixedly provided with a first conductive copper bar and a second conductive copper bar which are arranged on a wiring terminal of the connected electrical equipment. The insulation cavity 1 internally contains two cables, one end of each cable is welded on the connector socket, and the other end of each cable is fixed on the conductive copper bar through a screw. And the inside of the insulating cavity 1 is subjected to glue filling treatment and is sealed by using an insulating cover plate 3.

The insulating cavity 1 is made of nylon materials, and the insulating cavity 1 has good strength while insulation of the whole device is ensured, so that the insulating cavity can adapt to various use environments. And meanwhile, the nylon cavity is easy to process and has lower cost.

The connector socket is arranged at the front end of the insulating cavity 1, is an output end of an original wiring terminal of electrical equipment, and can be connected with other electrical equipment only by inserting a connector plug. The connector plug and the socket have uniqueness to plug, and can avoid reverse plug and misplug when the electrical equipment terminal is manually installed.

The insulating copper bar is arranged on the back of the insulating cavity 1, and is fixed by screws, and the bottom of the conductive copper bar is of a U-shaped structure (U-shaped notch 8). When the screw is unscrewed, the conductive copper bar can be finely adjusted up and down so as to adapt to electrical equipment with different heights. The top of the conductive copper bar is provided with two threaded holes, and the cable is fixed on the insulating copper bar through the screw when the inside of the insulating cavity body 1 is connected.

Four vertical plates are arranged at the bottom of the insulating cavity 1 and are close to one side of an insulating copper bar. The vertical piece and the insulating cavity 1 are integrally formed and used for isolating two copper bars and preventing short circuit. The vertical piece provides a safety clearance between the electrical equipment and an operator during operation, and prevents safety accidents caused by touching the copper bar.

The misplug preventing cable device has uniqueness in the use direction of connecting electrical equipment. When the misplug preventing cable device is installed, the fixing surface of the wiring terminal of the electrical equipment is attached to the back surface (namely, the end surface facing away from the connector socket) of the conductive copper bar. Because the front end of the insulating cavity 1 protrudes, if the inserting direction is opposite, the insulating cavity 1 can interfere with electrical equipment, and cannot be installed.

Example 2

As further optimization of embodiment 1, as shown in fig. 1 to 2, this embodiment further includes the following technical features on the basis of embodiment 1:

as shown in fig. 1 and 2, in an anti-misplug cable switching device, the connector socket 2 is fixed at the front end of the insulating cavity 1, and replaces the electrical equipment connecting terminal to be a new electrical equipment output interface. The first conductive copper bar and the second conductive copper bar are fixed on the insulating cavity 1 through screws. After the screws are unscrewed, the positions of the first conductive copper bar and the second conductive copper bar can be adjusted up and down to adapt to the wiring terminals (the first wiring terminal 51 and the second wiring terminal 52) of the electrical equipment. Threaded holes are reserved above the first conductive copper bar and the second conductive copper bar and are used for installing wires. The insulation cavity 1 is a main body structure of the misplug-preventing cable switching device, and the connector socket and the connecting cables of the first conductive copper bar and the second conductive copper bar are arranged in the insulation cavity. After the installation is completed, glue filling treatment is carried out on the inside of the insulating cavity, and the insulating cover plate 3 is installed to seal the misplug preventing cable switching device.

Wherein, the insulating cavity 1 is made of nylon material, and the whole cavity is square. Four vertical plates 6 are arranged at the bottom of the insulating cavity 1 and used for isolating the first conductive copper strips and the second conductive copper strips, and the vertical plates 6 isolate the conductive copper strips from surrounding space at the same time, so that personal safety is protected.

The installation direction of the misplug preventing cable switching device is unique. When the misplug preventing cable device is installed, the back surfaces of the first conductive copper bar and the second conductive copper bar (the front surface of the connector socket is the front surface of the misplug preventing cable device, the back surfaces of the misplug preventing cable device are the back surfaces of the first conductive copper bar and the second conductive copper bar) are attached to the fixing surface of the wiring terminal of the electrical equipment, and if the front surfaces of the first conductive copper bar and the second conductive copper bar are attached to the fixing surface of the wiring terminal of the electrical equipment, the insulating cavity 1 interferes with the electrical equipment.

During installation, the nuts of the wiring terminal of the electrical equipment are unscrewed, the first conductive copper bar and the second conductive copper bar are inserted between the wiring terminal screw rod and the nuts from top to bottom, and the nuts are locked. The other electrical devices connected thereto are interconnected by plugging the connector plug into the connector receptacle 2.

As described above, the present utility model can be preferably implemented.

The foregoing description of the preferred embodiment of the utility model is not intended to limit the utility model in any way, but rather to cover all modifications, equivalents, improvements and alternatives falling within the spirit and principles of the utility model.
