Description

Anti-drop anti-sticking switch wiring structure

[ technical field ] A method for producing a semiconductor device

The utility model relates to the technical field of electric appliances, in particular to the technical field of switches.

[ background of the utility model ]

At present switch wiring structure mostly adopts the screw structure of taking the pad, sets up limit structure, prevents in the transportation, perhaps the screw pine takes off to drop that appears in the wiring process. With the development of science and technology, the traditional manual screwdriver is replaced by the electric screwdriver, but the electric screwdriver is high in speed and large in torsion, so that the screwdriver does not stop rotating when a screw exits from a limiting position, the screw can be continuously ejected outwards, the limiting structure is damaged, the screw is clamped, even the screw slides, a terminal is displaced, and a switch cannot be normally used.

[ Utility model ] content

The utility model aims to solve the problems in the prior art and provides an anti-falling and anti-blocking switch wiring structure, which can prevent a screw from being damaged easily and can be loosened and tightened repeatedly.

In order to achieve the purpose, the utility model provides an anti-falling and anti-blocking switch wiring structure which comprises a limiting structure and a screw, wherein a wiring hole for inserting a wire is formed in a wiring terminal, a mounting hole is formed in the wiring terminal, the mounting hole is a threaded hole with two open ends, the mounting hole is communicated with the wiring hole, the screw is composed of a screw head, a stud and a tail which are sequentially connected, the stud is matched with the mounting hole, the tail is a cylinder with the outer diameter slightly smaller than the thread diameter of the mounting hole, the tail compresses the wire when the screw is screwed, the limiting structure is a part of a switch, the limiting structure can abut against the screw head, and the screw is only positioned in the mounting hole when the screw head is loosened and the screw head is abutted by the limiting structure.

Preferably, the bottom of the screw head comprises an integrated gasket, and the limiting structure is provided with a blocking body for blocking the gasket.

Preferably, the limiting structure comprises a stop ring, the lower end face of the stop ring is matched with the upper end face of the screw head, and the lower end face of the stop ring can be attached to the upper end face of the screw head.

Preferably, the screw is unscrewed until the tang is fully clear of the wire hole when the screw head is held against the stop structure.

The utility model has the beneficial effects that: according to the utility model, the tail is arranged at the bottom of the screw, so that when the screw is screwed to be abutted by the limiting structure, only the tail is arranged in the mounting hole, the tail can freely rotate in the mounting hole, the tail and the mounting hole are not easy to damage, and the tail can play a guiding role when the screw is screwed again, so that the screw can be conveniently screwed again.

The features and advantages of the present invention will be described in detail by embodiments in conjunction with the accompanying drawings.

[ description of the drawings ]

Fig. 1 is a front view of a wiring structure of an anti-drop and anti-jamming switch of the present invention.

In the figure: the device comprises a 1-screw, a 2-wiring terminal, a 3-limiting structure, a 10-gasket, a 11-screw head, a 12-stud, a 13-tail, a 20-wiring hole, a 21-mounting hole, a 30-blocking body and a 31-blocking ring.

[ detailed description ] A

Referring to fig. 1, the utility model relates to an anti-drop and anti-locking switch wiring structure, wherein the switch comprises a wiring terminal 2, and the anti-drop and anti-locking switch wiring structure is characterized in that: including limit structure 3, screw 1, be equipped with a wiring hole 20 that is used for inserting the wire on binding post 2, be equipped with a mounting hole 21 on binding post 2, mounting hole 21 is the equal open-ended screw hole in both ends, mounting hole 21 is linked together with wiring hole 20, screw 1 comprises screw head 11, double-screw bolt 12, the tail 13 that contracts that links to each other in proper order, and double-screw bolt 12 cooperatees with mounting hole 21, and the tail 13 that contracts is a cylinder that the external diameter slightly is less than the mounting hole 21 screw thread path, and the tail 13 compresses tightly the wire when screw 1 is screwed up, limit structure 3 is one part of switch, and limit structure 3 can support screw head 11, and screw 1 only has the tail 13 that contracts to be located mounting hole 21 when screw head 11 is supported by limit structure 3 by the loose screw head, screw head 11 bottom includes the gasket 10 of a, is equipped with the body 30 that blocks that is used for blocking gasket 10 on limit structure 3, limiting structure 3 includes a barrier ring 31, and the lower terminal surface of barrier ring 31 suits with the up end of screw head 11, and the lower terminal surface of barrier ring 31 can laminate mutually with the up end of screw head 11, screw 1 unscrews to screw head 11 and contracts tail 13 and leave wiring hole 20 completely when being supported by limiting structure 3.
