Description

Technical Field

[0001] The utility model belongs to the technical field of power switches, and in particular relates to a wire fixing structure for a power switch. Background Art

[0002] A power switch is an electronic component used to open and close a circuit and control the flow of current. Its main function is to control the switch tube to conduct and cut off at high speed through the circuit, converting direct current into high-frequency alternating current and providing it to the transformer for transformation, thereby generating one or more sets of required voltages. Switching power supplies are widely used in modern electronic devices due to their high-efficiency conversion, small size, light weight and high efficiency.

[0003] The power switch wires generally have no fixed wire structure and are arranged in a messy manner in the switch cover, which is not conducive to maintenance and wire management. After long-term use, the wiring is easily loosened, causing certain safety hazards. In order to solve the above problems, we propose a fixed wire structure for the power switch.

[0007] Furthermore, a plurality of through holes are provided on one side of the fireproof cover, a wire entry groove is provided on one side of the fireproof cover, a horizontal plate is fixedly installed on the inner bottom surface of the groove, and a plurality of distinguishing grooves are provided on one side surface of the horizontal plate.

[0008] Furthermore, the shape and size of the bolt groove are adapted to the bolt, and the bolt groove cooperates with the bolt thread.

[0009] Furthermore, the shape and size of the limiting groove are adapted to the limiting block, and the limiting groove and the limiting block are snap-fitted together.

[0010] Furthermore, the shape and size of the clamping plate are adapted to the side notches, the clamping plate and the side notches are slidably matched, the upper notches and the side notches are interconnected, and the number of the clamping plates is two.

[0011] The utility model has the following beneficial effects:

[0012] 1. By pressing the limit block, the spring is in a compressed state, and the slider drives the clamping plate to move to a suitable position. The limit block is released, and the spring is in an expanded state, so that the limit block and the limit groove are clamped and matched, and the wires are placed in the semicircular grooves respectively. The wires are clamped and fixed by the interaction force between the semicircular grooves and the semicircular protrusions. Then, the wires are wrapped around the "S"-shaped route and clamped in the semicircular grooves. The bolts are loosened, and the exposed copper wire ends of the wires are fixed in the bolt grooves by bolts. The bolts are tightened, and the wires are further fixed by the clamping effect of the clamping plate and the clamping effect of the semicircular grooves, which improves the problem that the wiring is easy to loosen and cause certain safety hazards.

[0013] 2. Fix the fireproof cover to the wall with screws through the through holes, pass the wires through the wire entry slots, and then classify them into the dividing slots. This improves the problem of messy arrangement and stacking of wires, which is not conducive to maintenance and wiring. Installing a fireproof cover reduces the fire problem that may be caused by aging of wires.
