Description

Technical Field

[0001] The utility model relates to a switch which is convenient for disassembling and assembling connecting wires. Background Art

[0002] A switch generally refers to an electronic component that can form an on-off circuit by operation. A shell is provided on the switch, and a wire hole is provided on the shell for allowing the connecting wires of the external corresponding circuit to enter the shell. After the external connecting wires are introduced into the shell, they cooperate with the dynamic conductive sheet and the static conductive sheet in the shell, so that the switch can form an on-off circuit when it is operated. A limiting spring sheet or other clamping structure is often also provided in the shell, so that the connecting wire is limited after entering the shell and connecting with the conductive sheet. However, the limiting spring sheet or other clamping structure will also make it very inconvenient to separate the two, affecting the subsequent adjustment and replacement. For this reason, a switch that can facilitate the disassembly and assembly of the connecting wire is provided on the market, and a limiting spring sheet, an adjustment hole and a movable block are provided on the shell, wherein the movable block and the limiting spring sheet are abutted against each other. , and the clearance between the movable block and the inner wall of the shell matches, the external device can be connected to the movable block inside the shell through the adjusting hole, and squeezed into the gap formed by the movable block and the inner wall of the shell, pushing the movable block, prompting it to move and drive the limiting spring sheet to deform and release the limit on the connecting line, so as to achieve the purpose of convenient disassembly. However, the prior art has high requirements for external devices during disassembly, and requires them to adapt to the shape of the gap formed by the adjusting hole and the movable block and the inner wall of the shell, which has certain inconveniences, and the way of inserting the external device into the gap and pushing is also easy to damage the matching surface corresponding to the movable block and the inner wall of the shell, especially when the shape of the external device does not match, the durability is poor. In addition, the way the movable block slides sideways also needs to occupy a large space in the shell. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a switch which is more adaptable, not easy to be damaged, requires less space and is convenient for disassembling and assembling connecting wires.

[0004] To achieve the above-mentioned purpose, the utility model provides a switch that is easy to disassemble and assemble connecting wires, including a shell, an adjusting block and a limiting spring piece, the shell including a wire entry hole for the connecting wire to pass through and an operating slot connecting the inside and outside of the shell, the limiting spring piece is arranged at a position close to the corresponding wire entry hole in the shell, and the limiting spring piece can be elastically pressed on the connecting wire that enters the shell through the wire entry hole, and form a one-way limit on the connecting wire in the direction of escape, the adjusting block is arranged at one side of the limiting spring piece and covers the operating slot, the operating slot can allow an external device to extend into and push the adjusting block, and the adjusting block can slide in the opposite direction to press against the limiting spring piece and release the one-way limit on the connecting wire under the push of the external device.

[0005] The advantages of adopting the above technical solution are as follows: A housing and a limiting elastic piece are provided. First, by arranging the limiting elastic piece near the wire inlet hole, the limiting elastic piece forms a one-way limit on the connecting wire passing through the wire inlet hole and into the housing. On this basis, an adjusting block and an operation through slot are further provided. The adjusting block covers the position of the operation through slot, and the operation through slot allows an external device to extend into it and push against the adjusting block. After being pushed, the adjusting block can slide reversely and press against the limiting elastic piece, releasing the one-way limit on the connecting wire. During the pushing process of the external device, the adjusting block only needs to move reversely, which requires less shape requirements for the external device performing the operation. And with only the driving method of pushing, it is not easy for the external device to damage the adjusting block. Even if it is damaged during the pushing process, it will not affect subsequent pushing, making the product more durable. In addition, the movement mode of the adjusting block can also reduce the occupation of the planar space inside the housing.

[0006] The utility model can be further arranged as follows: The adjusting block includes a lower part, and the lower part is inserted into the operation through slot, and the shape of the peripheral wall of the lower part and the inner wall of the operation through slot are adapted to each other and are arranged with a clearance fit.

[0007] Through further arrangement, on the one hand, the lower part inserted into the operation slot can enable the external device to come into contact with the adjusting block earlier and drive its displacement, reducing the length of the external device extending in. On the other hand, making the shape of the peripheral wall of the lower part and the inner wall of the operation through slot adapted to each other and having a clearance fit can form a guiding displacement between the lower part and the through slot when the external device pushes the adjusting block to slide.

[0008] The utility model can be further arranged as follows: The adjusting block includes a guiding part located on the side wall. The guiding part protrudes towards the direction of the limiting elastic piece, and the guiding part is arranged to gradually become smaller towards the direction away from the wire inlet hole.

[0009] Through further arrangement, by providing a guiding part protruding towards the direction of the limiting elastic piece on the side wall of the adjusting block and setting the guiding part to gradually become smaller towards the direction away from the wire inlet hole, the guiding part can more smoothly form an abutment with the limiting elastic piece at its smaller end. Subsequently, when the adjusting block is pushed and slides by the external device, the part of the guiding part in contact with the limiting elastic piece also gradually becomes larger, forming a pressing against the limiting elastic piece, and then gradually driving the limiting elastic piece to retract to release the one-way limit of the limiting elastic piece on the connecting wire.

[0010] The utility model can be further arranged as follows: A groove part is provided on the end surface of the lower part corresponding to the external opening of the operation through slot, and the groove part is arranged to gradually become larger towards its opening direction.

[0011] Through further arrangement, by providing a gradually larger groove part on the end surface of the lower part corresponding to the opening of the operation through slot, it can facilitate guiding for the external device and provide a limit after the external device enters, facilitating the operation of pushing the adjusting block by the external device.

[0012] The utility model can be further configured as follows: the limiting elastic piece is formed by folding a long strip metal piece for multiple times. The limiting elastic piece includes a first contact part and a second contact part respectively formed at its two ends. Both the first contact part and the second contact part are inclined and extended in a direction away from the wire passing hole.

[0013] Through the further configuration, the two ends of the limiting elastic piece formed by folding for multiple times form the first contact part and the second contact part, and the first contact part and the second contact part are inclined and extended in a direction away from the wire passing hole. Thus, when the connecting wire extends through the wire passing hole, the first contact part and the second contact part will be pushed by the connecting wire to change the inclination angle and form an elastic abutment with the connecting wire. After the connecting wire is inserted, when the action of withdrawing the connecting wire is performed, the first contact part and the second contact part will be driven by the connecting wire to expand and clamp on the connecting wire, thereby forming a one-way limit.

[0014] The utility model can be further configured as follows: the first contact part and the second contact part are arranged successively in a direction away from the wire passing hole. A bending part is arranged near the end of the second contact part. The first contact part and the second contact part are respectively in abutting and cooperating with the connecting wire through the end and the bending part.

[0015] Through the further configuration, the first contact part and the second contact part are arranged successively in a direction away from the wire passing hole, and a bending part is arranged at the end of the second contact part relatively far from the wire passing hole. The first contact part near the wire passing hole directly abuts against the connecting wire through the end to ensure the strength of the limit. Because during the movement of the adjusting block, it will first contact the first contact part and drive it to retract, and the second contact part contacts the connecting wire through the bending part, avoiding damage to itself or the connecting wire in the case where the degree of its retraction by the adjusting block is small.

[0016] The utility model can be further configured as follows: an adjacent first installation groove and a second installation groove are arranged in the housing. The first installation groove and the second installation groove are respectively in guiding and sliding cooperation with the limiting elastic piece and the adjusting block. A communication port through which the side wall of the adjusting block can extend into the first installation groove is arranged between the first installation groove and the second installation groove.

[0017] Through the further configuration, an adjacent first installation groove and a second installation groove are arranged in the housing, and the first installation groove and the second installation groove are respectively in guiding and sliding cooperation with the limiting elastic piece and the adjusting block, which is convenient for installing the limiting elastic piece and the adjusting block therein. Then a connection port is arranged between the first installation groove and the second installation groove, which is convenient for the guiding part on one side of the adjusting block to extend into the first installation groove through the connection port and form a cooperation with the limiting elastic piece.
