Detailed implementation manners

[0030] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the attached drawings and implementation examples. It should be understood that the specific implementation examples described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0031] Please refer to Figure 1 - Figure 6 , the present invention provides a multi-wire induction switch structure 8, including a fixing device 9 and a linear micro-motion positioning switch 10. A plurality of linear micro-motion positioning switches 10 are provided and are fixedly arranged side by side on the fixing device 9. One end of each linear micro-motion positioning switch 10 is pre-connected with a wire in advance, and other external wires are connected to the pre-connected wires by pressing the linear micro-motion positioning switch 10.

[0032] Further, the linear micro-motion positioning switch 10 includes a pressing part 11, an elastic member 12, an insulating accommodating part 13 and a metal fixing part 14. The elastic member 12 is sleeved on the pressing part 11. Part of the pressing part 11 is located inside the insulating accommodating part 13, and part is located outside the insulating accommodating part 13. The elastic member 12 is located outside the insulating accommodating part 13 and its two ends are respectively abutted against the pressing part 11 and the insulating accommodating part 13. The metal fixing part 14 is connected to one end of the insulating accommodating part 13 away from the elastic member 12. The pressing part 11 moves towards the metal fixing part 14 under the action of an external pressing force and compresses the elastic member 12 at the same time, and is pushed in the direction away from the metal fixing part 14 by the elastic force of the elastic member 12 when the external pressing force is removed.

[0033] A wire is pre-passed through the metal fixing part 14. Other external wires are electrically conducted and disconnected from the pre-passed wire by driving the pressing part 11 by an external moving device to press or cancel the pressing of the pressing part 11.

[0034] Preferably, the pressing part 11 is made of a conductive material. In this way, when the wire material with the wire exposed presses the pressing part 11, the pressing part 11 serves as an intermediate conductor to conduct electricity to the wire material pre-connected to the metal fixing part 14. Further preferably, the material of the pressing part 11 is copper, and the material of the metal fixing part 14 is aluminum.

[0035] It can be understood that the linear micro-motion positioning switch 10 is small in size, and the pressing force required by it is small and much smaller than the bending force of the external wire material. Therefore, the external wire material can easily press the pressing part 11 without being easily bent, which is beneficial to maintaining the pressing state for a long time and pressing multiple times.

[0036] Preferably, the elastic member 12 is a spring.

[0037] Further, the fixing device 9 includes a fixing base 91 and a locking structure 92. The fixing base 91 is fixedly connected to the locking structure 92. The locking structure 92 includes a first locking member 93 and a second locking member 94. The first locking member 93 and the second locking member 94 are integrally cylindrical. An insertion hole 95 is formed in the locking structure 92. The linear micro-motion positioning switch 10 is inserted into the insertion hole 95 and extends from both ends of the insertion hole 95. The shape and size of the insertion hole 95 match the shape and size of the cross-section of the insulating accommodation part 13. When the linear micro-motion positioning switch 10 is snapped into the insertion hole 95, the first locking member 93 and the second locking member 94 are screwed together, so that the linear micro-motion positioning switch 10 and the insertion hole 95 are fixed by interference fit.

[0038] Further, the fixing device 9 further includes a wire insertion part 96. The wire insertion part 96 is connected to one end of the locking structure 92 close to the pressing part 11. The wire insertion part 96 is fixedly connected to the locking structure 92. A funnel-shaped insertion hole 97 with a larger outer diameter and a smaller inner diameter is formed in the wire insertion part 96. The position of the insertion hole 97 is opposite to the position of the insertion hole 95. The setting of the insertion hole 97 facilitates the smooth insertion of the external wire material. And because the structure of the insertion hole 97 plays a role in guiding the wire, the inserted wire material will not be misaligned in direction and misaligned with the pressing part 11, resulting in ineffective pressing, which is beneficial to greatly improving the success rate of pressing between the wire material and the pressing part 11.

[0039] Further, the pressing part 11 includes a pressing stopper 111, a transmission column 112, and a contact and rebound stopper 113. The pressing stopper 111 is connected to one end of the transmission column 112, and the contact and rebound member is connected to the other end of the transmission column 112. Among them, a first counterbore 114 is provided at one end of the transmission column 112 away from the pressing stopper 111. The contact and rebound stopper 113 includes a contact body 115 and a first fixing member 116. The contact body 115 is fixedly connected to the first fixing member 116. The shape and size of the first fixing member 116 match the shape and size of the first counterbore 114. The contact and rebound stopper 113 is connected to the transmission column 112 by inserting the first fixing member 116 into the first counterbore 114. The contact and rebound stopper 113 and the first counterbore 114 are relatively fixed by interference fit, without the need to rely on external bolts or other objects. The connection method is simple, which is beneficial to the connection of small objects and reduces the expenditure of material costs.

[0040] Further, a first through hole 131 is provided at one end of the insulating accommodation part 13. The shape and size of the first through hole 131 match the shape and size of the cross section of the transmission column 112. A part of the transmission column 112 is located outside the insulating accommodation part 13, and a part of it passes through from the first through hole 131 and is located inside the insulating accommodation part 13. The setting of the first through hole 131 limits the movement direction of the transmission column 112, so that the transmission column 112 can only move in the axial direction of the transmission column 112, playing a guiding role and reducing the occurrence of the situation where the contact and rebound stopper 113 does not contact the wire due to the oblique movement of the transmission column 112, resulting in conductive failure.

[0041] Preferably, the dimension of the transmission column 112 in the radial direction is smaller than the dimension of the contact body 115 in the radial direction. In this way, the contact body 115 cannot pass through the first through hole 131, reducing the occurrence of the situation where the connection between the pressing part 11 and the insulating accommodation part 13 fails due to the contact body 115 passing through the first through hole 131 during rebound, which is beneficial to improving the connection stability and service life.

[0042] Further, a second counterbore 132 is formed at one end of the insulating accommodating portion 13 away from the pressing and blocking member 111. The metal fixing portion 14 includes a main body portion 141 and a second fixing member 142. The main body portion 141 is fixedly connected to the second fixing member 142. The shape and size of the second fixing member 142 match the shape and size of the second counterbore 132. The metal fixing portion 14 is connected to the insulating accommodating portion 13 by inserting the second fixing member 142 into the second counterbore 132. Among them, the contact body 115 is also accommodated in the second counterbore 132. The metal fixing portion 14 and the second counterbore 132 of the insulating accommodating portion 13 are relatively fixed by interference fit, without the need to rely on external bolts or other objects. The connection method is simple and is conducive to the connection of small objects, reducing the expenditure of material costs; at the same time, it also reduces the possibility that the pressing portion 11 connects electricity to external objects through connection objects such as bolts and causes mis-discharge, which is conducive to improving the safety factor.

[0043] Preferably, the opening size of the second counterbore 132 is larger than the opening size of the first through hole 131.

[0044] It can be understood that the multi-wire induction switch structure 8 of the present invention can be connected to an external detection device to detect and monitor the connection state between each linear micro-motion positioning switch 10 and the wire in real time, and timely check and repair the linear micro-motion positioning switch 10 that should be connected but fails to be connected, so as to ensure the work progress and eliminate potential safety hazards.

[0045] Compared with the prior art, the linear micro-motion positioning switch and the multi-wire induction switch structure of the present invention have the following advantages:

[0046] Without the drive of a power, magnetic or induction device, the circuit can be connected and disconnected, effectively avoiding the situation of losing the switch function in the case of the failure of power, magnetism or induction, maintaining the original switch state, which is conducive to reducing the losses of enterprises caused by the failure of the switch and may lead to machine shutdown, and is also conducive to improving the safety factor.

[0047] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any modifications, equivalent replacements, and improvements made within the concept of the present utility model shall be included in the patent protection scope of the present utility model.
