Description

TECHNICAL FIELD

[0001] The present application relates to the field of low-voltage electricity, in particular to a connection structure of a switch device. BACKGROUND

[0002] The button switch product is composed of a button switch device, a contact module and a connection structure for connecting the button switch device and the contact module. The connection structure of the button switch device is generally divided into two ways: a screw fastening type connection structure and a toggle buckle type connection structure.

[0003] However, both of the two connection structures have their own problems that are difficult to solve. For example, for the screw fastening type connection structure, the button switch device is locked by using a screw, and the installation process is complicated, and a larger operation space is required for the workers during the installation, maintenance and disassembly process, resulting in low installation efficiency; for the toggle buckle type connection structure, the locking of the button switch device is achieved by rotating the toggle ring to make the buckle structure thereon and the limiting protrusion on the base circumferentially dislocated, but since the action of the toggle ring will cause the change of the opening and closing of the button switch device, it is easy to cause the occurrence of misoperation; in addition, the limiting point on the toggle ring is easy to age and has poor reliability.

[0004] In recent years, a toggle buckle type connection structure driven by spring force has also appeared in the market. The toggle ring and the base are connected by a spring. When the button switch device is locked, the toggle ring is fixed at the locking position by the limiting point thereon, and at this time the spring is compressed / stretched; once the limiting of the limiting point is released, the toggle ring is automatically reset under the action of the spring, and the button switch device is unlocked. Although this way further simplifies the disassembly process of the button switch device, since the spring force is used as the driving force for resetting the toggle ring, it is more likely to cause misoperation of the switch device in the working environment, which not only easily leads to instrument failure, but also has serious safety hazards.

[0039] Figure 1 This is an assembly diagram illustrating the connection structure of the switching device of the present invention.

[0040] The connecting structure of the switch device of the present application is between the switch device 30 and the contact module 40. The connecting structure of the switch device comprises the base 10 and the locking mechanism 20. The base 10 is provided with a mounting hole 11 (see Figure 4 ) and a buckle. The switch device 30 can be inserted into the mounting hole 11 and fixed to the base 10. The buckle of the base 10 is used to be clamped with the buckle of the contact module 40 to fix the contact module 40.

[0041] The locking mechanism 20 comprises a knob 21, a locking ring 22 and an elastic member 23. The knob 21 and the locking ring 22 can rotate relative to each other after being assembled. After the locking mechanism 20 is assembled with the base 10, the through hole of the locking ring 22 is through the through hole of the mounting hole 11, the elastic member 23 is connected to the locking ring 22, and specifically, the elastic member 23 can be connected between the locking ring 22 and the base 10; after the switch device 30 is inserted into the mounting hole 11 and the locking ring 22, the switch device 30 can be jointly locked by the locking portion 222 of the locking ring 22 and the limiting protrusion 12 (see Figure 4 ) on the base 10. The elastic member 23 can be a spring.

[0042] The base 10 is further provided with a limiting hole 14 and a limiting slot 15. After the locking mechanism 20 is assembled into the base 10, the first protrusion 2111 on the knob 21 is buckled into the limiting hole 14, and the second protrusion 2112 is buckled into the limiting slot 15. The limiting hole 14 is used to limit the knob 21 at the first position; the limiting slot 15 is used to limit the movement of the knob 21 between the first position and the second position.

[0043] Figure 2 It is an exploded view for illustrating the connecting structure of the switch device of the present application.

[0044] Referring to Figure 2 , the knob 21 comprises a knob body 211, two connecting arms 213 and a driving portion 212. The connecting arm 213 is arranged at one end of the knob body 211 close to the locking ring 22, and the end of each connecting arm 213 is provided with a driving portion 212. The two driving portions 212 are oppositely arranged driving protrusions.

[0045] The locking ring 22 comprises a locking ring body 221, a locking portion 222 and a connecting slot 223 (see Figure 3) and the elastic member connecting portion 224. The locking portion 222 is a locking protrusion on the locking ring body 221, which protrudes radially from the inner wall of the locking ring body 221, and can be symmetrically distributed on the locking ring body 221. The locking protrusion can lock the switch device 30 after cooperating with the limiting protrusion 12 of the base 10. The connecting groove 223 is arranged on the locking ring body 221, and is connected with the driving protrusion of the knob 21, and the driving protrusion can slide in the connecting groove 223. The elastic member connecting portion 224 is arranged on the outer wall of the locking ring body 221, and is used for connecting the elastic member 23. The base 10 is also provided with a spring mounting hole 13 (see Figure 4 ). The elastic member 23 can be mounted into the base 10 through the spring mounting hole 13.

[0046] Figure 3 The structure diagram of the knob and the locking ring in Figure 1 is shown from the perspective of observing the switch device from the contact module.

[0047] Referring to Figure 3 , one end of the knob body 211 towards the locking ring 22 is arranged corresponding to the shape of the locking ring 22. When the knob 21 is buckled on the locking ring 22, the two connecting arms 213 are clamped on the locking ring 22, and the two driving portions 212 are respectively located in the two connecting grooves 223. The driving portion 212 can slide in the connecting groove 223 by rotating the locking ring 22, and the driving portion 212 can abut against one side wall 2231 of the connecting groove 223 and drive the locking ring 22 to rotate by rotating the knob 21.

[0048] In addition, the knob 21 of the present application can also be implemented in other ways. For example, the knob 21 is arranged in other shapes; for example, only one connecting arm 213 and one driving portion 212 are arranged; for example, a driving groove is arranged on the knob 21, and a connecting protrusion is arranged on the locking ring 22, the connecting protrusion can slide in the driving groove, and the driving groove can abut against the connecting protrusion to drive the locking ring 22 to rotate.

[0049] Figure 4 , Figure 5 , Figure 6 is a structure diagram for illustrating the connecting structure of the switch device of the present application. In Figure 4 , the knob 21 is located at the first position, and the first protrusion 2111 is limited by the limiting hole 14; Figure 5 , the knob 21 is located at the first position, the first protrusion 2111 is limited by the limiting hole 14, and the locking portion 222 is located at the dismounting position; Figure 6 , the knob 21 is located at the second position, the first protrusion 2111 is disengaged from the limiting hole 14, and the locking portion 222 is located at the dismounting position.

[0050] The following will be described in combination with Figure 4 andFigure 5 The installation process of the switch device 30 will be described below.

[0051] Referring to Figure 4 When the switch device 30 is not installed, the locking portion 222 on the locking ring 22 is circumferentially misaligned with the limiting protrusion 12 on the base 10. When the switch device 30 is inserted into the installation hole 11 of the base 10, the switch device 30 abuts against the driving slope 2221 of the locking portion 222 and drives the locking ring 22 to rotate clockwise.

[0052] When the locking ring 22 is rotated to the dismounting position shown in Figure 5 , the locking portion 222 is circumferentially aligned with the limiting protrusion 12 of the base 10. During the rotation of the locking ring 22 from the Figure 4 position to the Figure 5 position, the elastic member 23 is compressed to store energy. When the switch device 30 is continuously inserted into the installation hole 11, the limiting protrusion 12 and the locking portion 222 slide into the axial groove on the switch device 30.

[0053] When the switch device 30 is further inserted into the installation hole 11, the locking ring 22 rotates counterclockwise due to the force of the elastic member 23 on the locking ring 22 when the locking portion 222 slides to the position where the axial groove and the circumferential groove on the switch device 30 intersect, and the locking portion 222 slides into the circumferential groove of the switch device 30. At this time, the locking portion 222 is located at the Figure 4 position shown in the figure, and the switch device 30 is locked by the locking portion 222 of the locking ring 22 and the limiting protrusion 12 of the base 10. During the installation process, the driving member 21 and the locking ring 22 can rotate relative to each other, so that the installation of the switch device can be quickly completed without the need to push the driving member 21, and in addition, the elastic force of the elastic member 23 can drive the locking ring 22 to reset to the locking position to achieve quick locking of the switch device.

[0054] The dismounting process of the switch device 30 will be described below with reference to Figure 4 and Figure 6 .

[0055] Referring to Figure 4 , the driving member 21 is located at the first position, and the first protrusion 2111 of the driving member 21 is disengaged from the limiting hole 14 by pushing the driving member 21 exposed to the base by hand or using a screwdriver or the like. At this time, since the elastic member 23 has not stored energy, the locking ring 22 remains at the Figure 4 position shown in the figure without external force, and the switch device is still in the locked state. When the driving member 21 is pushed clockwise to move to the second position, the driving portion 212 (i.e., the driving protrusion) abuts against the side wall 2231 of the connecting groove 223 and drives the locking ring 22 to rotate clockwise together with the driving member 21.

[0056] When the knob 21 moves to the second position, the locking ring 22 rotates to the Figure 6 disassembling position shown in the middle of the figure, following the knob 21. At this time, the locking portion 222 is in circumferential coincidence with the limiting protrusion 12 of the base 10; at this time, the switch device 30 is pulled outwards, the locking portion 222 can slide out of the axial groove of the switch device 30, and the switch device 30 can be smoothly disassembled. In the process of rotating the locking ring 22 from the Figure 4 position (first position) to the Figure 6 position (second position), the elastic member 23 stores energy.

[0057] The connection structure of the switch device of the present application can realize quick installation and locking of the switch device without the need of operating the knob 21 during installation; if the locking of the switch device by the locking ring 22 is to be released, the elastic force of the elastic member needs to be overcome, which can prevent misoperation in the working environment, and has high reliability and is more secure.
