Detailed Description
Referring to fig. 1, the dual power switching device provided by the utility model comprises a dual power switching switch 1 with a plurality of wiring holes 11, wherein a guide post 2 is fixed on the dual power switching switch 1 and positioned on one side of the wiring holes 11, a limiting plate 21 is arranged at the top end of the guide post 2, a clamping assembly 3 for clamping an electric wire is sleeved on the guide post 2 in a sliding manner, and a spring 4 in a compressed state is sleeved on the outer side of the guide post 2 and positioned between the limiting plate 21 and the clamping assembly 3.
When the wiring, insert the electric wire in the wiring hole 11 and switch on, then carry out the centre gripping fixedly to the wire through clamping component 3, in normal use, if the electric wire receives external pulling force, the external force that the spring 4 received can cushion the electric wire, reduce the risk that the electric wire drops, in addition, because spring 4 is in compressed state, can give clamping component 3 a force of keeping away from wiring hole 11 direction earlier before clamping component 3 carries out the centre gripping to the electric wire, after clamping component 3 forms the centre gripping to the electric wire, remove the external force of exerting on clamping component 3, clamping component 3 receives the effect of spring 4 elasticity to drive the electric wire to move in the wiring hole 11, thereby can further make wire connection's more firm.
In the above embodiment, the clamping assembly 3 includes the first plate 31 that is sleeved on the guide post 2 and the second plate 33 that is connected to the first plate 31 by the fastening bolt 32, and specifically referring to fig. 2, when clamping, the electric wire is located between the first plate 31 and the second plate 33, and when the first plate 31 and the second plate 33 are connected by the fastening bolt 32, the clamping is formed on the electric wire.
The first plate 31 may be provided with a threaded hole adapted to be screwed with the fastening bolt 32, and the fastening bolt 32 may be rotatably connected with the second plate 33, when the screwed portion of the fastening bolt 32 enters the threaded hole, the fastening bolt 32 is rotated, and the fastening bolt 32 drives the second plate 33 to approach the first plate 31 together to clamp the electric wire.
It should be further noted that, the first plate 31 has a protruding portion 311 extending toward the connection hole 11, the second plate 33 has a recess 321 capable of being inserted into the protruding portion 311, and a wire is clamped between an outer end wall of the protruding portion 311 and an inner end wall of the recess 321.
To better protect the electric wire, rubber pads are fixed on the outer end wall of the protruding portion 311 and the inner end wall of the recessed portion 321, and meanwhile, the rubber pads can also increase friction force between the clamping assembly 3 and the electric wire.
As shown in fig. 1, the dual power supply change-over switch 1 can be divided into two groups of wiring holes 11 respectively located at two sides, and the first plate 31 and the second plate 33 in the utility model can be adaptively arranged into two groups, and the two groups of the first plate 31 and the second plate 33 respectively clamp and fix wires in the two groups of wiring holes 11.
It should be further noted that, the existing wiring hole 11 is usually in an open state, after the service time is long, dust or inflammable impurities may be accumulated in the wiring hole 11, the dust accumulation affects the heat dissipation effect of the wire connection part, and the inflammable impurities may fire to cause potential safety hazards when the temperature is too high, so as to reduce the impurities and dust falling into the wiring hole 11, the first plate 31 and the second plate 33 can be attached to the opening end wall of the wiring hole 11 to form a shielding for the opening of the wiring hole 11, and in addition, the spring 4 is arranged to enable the first plate 31, the second plate 33 and the opening end wall of the wiring hole 11 to be attached more tightly, thereby improving the tightness of the wiring hole 11.
In the above embodiment, if the area covered by the first plate 31 is too large because the first plate 31 is fitted over the guide post 2, the communication of the electric wire into the wiring hole 11 will be affected, and thus, in order to avoid the above, the area of the portion of the opening of the wiring hole 11 covered by the first plate 31 is smaller than the area of the portion covered by the second plate 33.
After the service time of the dual power supply switching device is prolonged, the elasticity of the spring 4 is reduced, the spring 4 needs to be replaced and maintained, an internal thread hole is formed in the limiting plate 21 for conveniently replacing the spring 4, and an external thread which is screwed with the internal thread hole in an adapting mode is formed in the guide post 2, and the spring 4 needs to be replaced.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
