Description

Technical Field

[0001] This utility model relates to the field of switch technology, and more specifically, to a novel micro switch. Background Technology

[0002] A micro switch is a switch with a small contact gap and a quick-acting mechanism. It operates with a specified stroke and force, enclosed in a housing, and has an external actuator. Because of its small contact gap, it is called a micro switch, also known as a sensitive switch. Its electrical symbol is SM. It is widely used in electronic equipment, instruments, mining, power systems, household appliances, electrical equipment, car door locks, car seats, lawnmowers, and other fields.

[0003] Existing microswitches, such as the utility model patent with patent application number 2017206064913, disclose a microswitch including a housing and a first terminal, a second terminal, a movable spring, an elastic connector, a button, and an annular waterproof cap disposed in the housing. The housing has a receiving space for accommodating the first terminal, the second terminal, the movable spring, and the elastic connector, a button slot communicating with the receiving space, and a waterproof groove communicating with the outer end of the button slot. The first terminal and the second terminal extend out of the housing respectively. The elastic connector is connected between the movable spring and the first terminal. The button is telescopically positioned in the button slot. The waterproof cap is tightly fitted on the button and embedded in the waterproof groove.

[0004] Existing microswitches have relatively long internal elastic supports, resulting in poor sensitivity. Furthermore, the elastic support is only connected to the main body via a single rod. After prolonged use, the elastic support may fail to stably support the button, moving spring, and spring, posing a potential quality hazard of the switch falling apart. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of micro switch to solve the above-mentioned technical problems.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a novel micro switch, comprising: a housing; a switching component disposed within the housing; an elastic bracket disposed within the housing; a pressing component disposed on the housing; and a waterproof component disposed on the housing corresponding to and adapted to the pressing component; the elastic bracket comprising: a connecting portion; the connecting portion being connected to the switching component; two support rod portions disposed on the connecting portion; one end of the pressing component abutting against the support rod portions; an embedding portion disposed on the support rod portions; and the embedding portion abutting against the switching component.

[0007] Pressing the pressing component pushes the two support rods, causing them to rotate around the contact point between the embedded part and the switching component. The connecting part also rotates around the contact point between the embedded part and the switching component, thereby causing the switching component to change the switch state. Since the switching component connects the two support rods via the connecting part, when pressed, the two support rods are pressed by the pressing component and move synchronously. Furthermore, since both the embedded part and the connecting part are located on the two support rods, the stability of the connection between the support rods and the pressing component, and between the embedded part and the switching component, is ensured when pressed.

[0008] Optionally, the switching assembly includes: a connecting spring and a movable spring; one end of the connecting spring is fixed to the connecting part, and the other end is fixed to the movable spring; a fixed terminal, a normally open terminal, and a normally closed terminal are provided on the housing; both of the embedded parts abut against the fixed terminal; one end of the movable spring abuts against the fixed terminal; when the pressing assembly is not pressed, the other end of the movable spring contacts the normally closed terminal and conducts electricity; when the pressing assembly is pressed, the other end of the movable spring contacts the normally open terminal and conducts electricity.

[0009] When the pressing component is compressed, it pushes the support rod, which in turn moves the connecting part around the contact point between the embedded part and the fixed terminal. The connecting part pulls the connecting spring, which in turn moves the movable spring piece, separating its other end from the normally closed terminal. After moving a certain distance, the other end of the movable spring piece contacts the normally open terminal, at which point the fixed terminal is connected to the normally open terminal via the movable spring piece. When the compression of the pressing component stops, the connecting spring returns to its original position, pulling the connecting part towards the fixed terminal. The connecting part then moves the support rod around the contact point between the embedded part and the fixed terminal, separating the other end of the movable spring piece from the normally open terminal and contacting the normally closed terminal. At this point, the fixed terminal is connected to the normally closed terminal via the movable spring piece.

[0010] Optionally, a normally open contact that corresponds to and is adapted to the moving spring is provided on the normally open terminal.

[0011] The moving spring contacts the normally open contact, thus connecting the fixed terminal and the normally open terminal. By providing a normally open contact on the normally open terminal, the contact sensitivity between the moving spring and the normally open terminal can be improved.

[0012] Optionally, a normally closed contact that corresponds to and is adapted to the moving spring is provided on the normally closed terminal.

[0013] The moving spring contacts the normally closed contact, thus connecting the fixed terminal and the normally closed terminal. By providing a normally closed contact on the normally closed terminal, the contact sensitivity between the moving spring and the normally closed terminal can be improved.

[0014] Optionally, the moving spring is provided with a spring contact point.

[0015] By setting spring contacts, the moving spring can contact the normally open and normally closed contacts respectively, further improving the conductivity between the moving spring and the normally open and normally closed terminals.

[0016] Optionally, the pressing assembly includes: a transmission column; the waterproof assembly is disposed on the transmission column; a pressing head is disposed at one end of the transmission column; a U-shaped block is disposed at the other end of the transmission column; an arc-shaped block is disposed inside the U-shaped block; and the arc-shaped block abuts against the two support rod portions.

[0017] Pushing the pressing head moves it, causing the transmission column to move downwards, which in turn moves the U-shaped block downwards. At this time, the arc-shaped block inside the U-shaped block pushes the two support rods to move, and the two support rods slide along the outer wall of the arc-shaped block, thus switching the on / off state of the micro switch. The upper end of the pressing head is hemispherical.

[0018] Optionally, the waterproof component includes: a sealing ring; a sealing ring disposed on the inner wall of the sealing ring; the sealing ring being embedded in the transmission column; one end of the sealing ring being sleeved on the transmission column; and the other end of the sealing ring being embedded in the housing.

[0019] By setting a sealing ring to wrap around the outside of the transmission column, embedding one end of the sealing ring into the housing, and fitting a sealing ring on the sealing ring and embedding the sealing ring into the transmission column, the connection between the transmission column and the housing can be sealed, preventing moisture or dust from entering the micro switch through the gap between the transmission column and the housing, thus improving the waterproof reliability of the micro switch.

[0020] Optionally, a reinforcing rod is provided between the two support rods; one end of the reinforcing rod is fixed to one support rod and the other end is fixed to the other support rod.

[0021] By setting a reinforcing rod, the middle parts of the two support rods can be connected and supported, thereby improving the connection strength between the two support rods.

[0022] In summary, this utility model has the following beneficial effects: Pressing the pressing component pushes two support rods, causing them to rotate around the contact point between the embedded part and the switching component. The connecting part also rotates around the contact point between the embedded part and the switching component, thereby driving the switching component to change the switch state. Since the switching component connects the two support rods through the connecting part, when pressed, the two support rods are pressed by the pressing component and move synchronously. Furthermore, since both the embedded part and the connecting part are located on the two support rods, the stability of the connection between the support rods and the pressing component, and between the embedded part and the switching component, can be ensured when pressing.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Example 1

[0031] This embodiment provides a novel micro switch, such as Figure 1-3As shown, it includes: a housing 1; a switching assembly disposed within the housing 1; an elastic bracket disposed within the housing 1; a pressing assembly 4 disposed on the housing 1; and a waterproof assembly 6 disposed on the housing 1 corresponding to and adapted to the pressing assembly 4. The elastic bracket includes: a connecting portion 31; the connecting portion 31 is connected to the switching assembly; two support rod portions 32 are disposed on the connecting portion 31; one end of the pressing assembly 4 abuts against the support rod portion 32; and an embedding portion 33 is disposed on the support rod portion 32; the embedding portion 33 abuts against the switching assembly.

[0032] Pressing the pressing component 4 pushes the two support rods 32, causing them to rotate around the contact point between the embedded part 33 and the switching component. Simultaneously, the connecting part 31 rotates around the contact point between the embedded part 33 and the switching component, thereby causing the switching component to change its state. Since the switching component connects the two support rods 32 via the connecting part 31, when pressed, the two support rods 32 are pressed by the pressing component 4 and move synchronously. Furthermore, since both the embedded part 33 and the connecting part 31 are located on the two support rods 32, the stability of the connection between the support rods 32 and the pressing component 4, and between the embedded part 33 and the switching component, is ensured when pressed.

[0033] Optionally, the switching assembly includes: a connecting spring 21 and a movable spring piece 22; one end of the connecting spring 21 is fixed to the connecting part 31, and the other end is fixed to the movable spring piece 22; a fixed terminal 23, a normally open terminal 24, and a normally closed terminal 25 are provided on the housing 1; both of the embedded parts 33 abut against the fixed terminal 23; one end of the movable spring piece 22 abuts against the fixed terminal 23; when the pressing assembly 4 is not pressed, the other end of the movable spring piece 22 contacts and conducts with the normally closed terminal 25; when the pressing assembly 4 is pressed, the other end of the movable spring piece 22 contacts and conducts with the normally open terminal 24.

[0034] When the pressing component 4 is compressed, it pushes the support rod 32. The support rod 32 moves the connecting part 31 around the abutment of the embedded part 33 and the fixed terminal 23. The connecting part 31 pulls the connecting spring 21, which moves the movable spring piece 22, causing the other end of the movable spring piece 22 to separate from the normally closed terminal 25. After moving a certain distance, the other end of the movable spring piece 22 contacts the normally open terminal 24. At this time, the fixed terminal 23 is connected to the normally open terminal 24 through the movable spring piece 22. After the compression of the pressing component 4 stops, the connecting spring 21 returns to its original position and pulls the connecting part 31 toward the fixed terminal 23. The connecting part 31 moves the support rod 32 around the abutment of the embedded part 33 and the fixed terminal 23, causing the other end of the movable spring piece 22 to separate from the normally open terminal 24 and contact the normally closed terminal 25. At this time, the fixed terminal 23 is connected to the normally closed terminal 25 through the movable spring piece 22.

[0035] Optionally, a normally open contact 7 corresponding to and adapted to the moving spring 22 is provided on the normally open terminal 24.

[0036] The movable spring 22 contacts the normally open contact 7, thus connecting the fixed terminal 23 and the normally open terminal 24. By providing the normally open contact 7 on the normally open terminal 24, the contact sensitivity between the movable spring 22 and the normally open terminal 24 can be improved.

[0037] Optionally, a normally closed contact 8 that corresponds to and is adapted to the moving spring 22 is provided on the normally closed terminal 25.

[0038] The movable spring 22 contacts the normally closed contact 8, thus connecting the fixed terminal 23 and the normally closed terminal 25. By providing the normally closed contact 8 on the normally closed terminal 25, the contact sensitivity between the movable spring 22 and the normally closed terminal 25 can be improved.

[0039] Optionally, the movable spring 22 is provided with a spring contact point 9.

[0040] By setting the spring contact 9, the moving spring 22 can contact the normally open contact 7 and the normally closed contact 8 respectively through the spring contact 9, which further improves the conduction performance of the moving spring 22 with the normally open terminal 24 and the normally closed terminal 25.

[0041] Optionally, a reinforcing rod 5 is provided between the two support rod portions 32; one end of the reinforcing rod 5 is fixed to one support rod portion 32, and the other end is fixed to the other support rod portion 32.

[0042] By setting the reinforcing rod 5, the middle parts of the two support rod parts 32 can be connected and the two support rod parts 32 can be supported, thereby improving the connection strength of the two support rod parts 32.

Simultaneously, the connecting part 31 rotates around the contact point between the embedded part 33 and the switching component, thereby causing the switching component to change its state. Since the switching component connects the two support rods 32 via the connecting part 31, when pressed, the two support rods 32 are pressed by the pressing component 4 and move synchronously.
