when the wires are connected with the connector, each wire is electrically connected with the conductive base 301 through the claw head 2048, the elastic rod 2047, the outer guide sleeve 2041, the conductive sheet 309, the conductive body 307, the fuse 306, the push block 305 and the connection wire 310, all the parts are supported by conductive materials, such as copper, and the rest parts are made of insulating materials or are provided with insulating layers on the surfaces, in addition, after the connection is completed, the claw head 2048 and part of the elastic rod 2047 are still left outside, insulating layers are arranged except the side surface of the claw head 2048 facing the axial lead of the driving shaft 2043, and the rest surfaces of the claw head 2048 and the outer surface of the elastic rod 2047 are all provided with insulating layers to prevent electric shock, and further, an insulating jacket made of insulating materials can be arranged at the connection position;
after the wires are connected with the connector, the wires are electrically connected through the conductive base 301.
When an overload or short circuit occurs in a circuit where a certain wire is located, the corresponding fuse 306 is blown, so that the circuit with the problem is disconnected in time, in addition, the third spring 308 releases the elastic force, so that the push block 305 approaches the insulating sleeve 302, under the cooperation of the first inclined plane and the second inclined plane, the insulating sleeve 302 is jacked up, and the conductive seat 301 and all the conductive sheets 309 are moved together, so that the rest of the conductive sheets 309 are separated from contact with the corresponding outer guide sleeve 2041, and all the conductive connections in the connector are disconnected.
Example III
The number of connection assemblies 204 on each connector is limited, for example, in the present embodiment, the connector is in a rectangular shape, the connection assemblies 204 are provided with four groups, when wiring, the number of the connection assemblies 204 on the redundant connectors is required for one to enter and to go out, that is, one connector cannot meet the requirement of wiring, two connectors can be spliced together for use, specifically, referring to fig. 8, the splicing assembly of two connectors is realized by the cooperation of the electric wires and the connection assemblies 204 on the two adjacent connectors, but thus, the electric wires are required to cooperate, if the electrician does not carry the electric wires, the splicing cannot be performed, and therefore:
referring to fig. 9, the elastic rod 2047 and the claw head 2048 are not provided on the connection ring 2044 on any one of the connection assemblies 204 on the connector, but the following structure is provided: a connecting shaft 205 extends from one side of the connecting ring 2044 away from the rotating shaft 201, and a connector 206 is arranged at the tail end of the connecting shaft 205; thus, when a plurality of connectors are required to be assembled, the connection head 206 can be extended and clamped by the claw head 2048 on the other connector, thereby realizing the assembly.
Further, due to the arrangement of the connectors 206, there is no connection assembly 204 connected to the electric wires for each connector, and thus screw holes 207 may be provided on the connectors 206, so that the connection assembly 204 where the connectors 206 are located can be connected to the electric wires as well.
The present invention is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present invention.
