Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically to a light-emitting tactile switch with an external support. Background Technology

[0002] A tactile switch is a common electronic component, often used for switching control in circuits. Its characteristics include triggering the closure of the circuit by pressing and automatically returning to the initial state after being released. It has advantages such as small size, easy operation and fast response.

[0003] Currently, the structure of commonly used tactile switches is relatively simple. They are usually used as independent units. The main body of the tactile switch is fixed to the surface of the circuit board by soldering pins. The soldering method leaves a gap between the tactile switch and the circuit board. The existence of the gap allows the tactile switch to deform under external force. During the long-term pressing and triggering process, the bottom of the tactile switch is prone to loosening. To address this, a light-emitting tactile switch with an external support is proposed. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments, highlighting the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0027] Example:

[0028] like Figure 1 - Figure 6 As shown, this utility model provides a light-emitting tactile switch with an outer bracket, including a switch base 1, a light-emitting component 2 installed at the bottom of the switch base 1, a press trigger component 3 sleeved inside the switch base 1, and an anti-loosening support component 4 sleeved outside the switch base 1.

[0029] The anti-loosening support assembly 4 includes a support base body 41, a switch base compartment 42, and a connection blocking part 43. The switch base compartment 42 is provided inside the support base body 41. The support base body 41 is sleeved on the outside of the switch base 1 through the switch base compartment 42. The connection blocking part 43 is formed on both sides of the support base body 41.

[0030] The support base body 41 limits the position of the switch base 1 by connecting the blocking part 43 and nesting with the switch base 1. The switch base 1 is fixed inside the support base body 41 and supported by the support base body 41. Under the support of the support base body 41, the gap between the switch base 1 and the circuit board is filled, and the switch base 1 will not deform downward due to pressing, thus avoiding the loosening of the switch base 1.

[0031] The anti-loosening support assembly 4 also includes a grounding foot 44 and a clip 45;

[0032] The grounding foot 44 is formed at the bottom corner of the support base body 41, and the buckle 45 is formed at the middle position of the side of the grounding foot 44. The grounding foot 44 can leave an observation gap between the support base body 41 and the circuit board for equipment maintenance. The buckle 45 can be used to snap the support base body 41 to external equipment, improving the stability of the connection. It can also be used as a connection interface for external equipment.

[0033] The switch base 1 includes a switch base body 11, a key compartment 12, an LED bead pin limiting part 13, a press clearance groove 14, a power connection pin 15, and a spring 16;

[0034] The key press compartment 12 is located inside the switch base body 11. The left and right sides of the switch base body 11 are formed with LED lamp bead pin limiting parts 13 that cooperate with the light-emitting component 2. The front and rear sides of the switch base body 11 are formed with pressing relief grooves 14 that cooperate with the light-emitting component 2. Two sets of power-connecting pins 15 are provided, and the two sets of power-connecting pins 15 are respectively installed on both sides of the bottom end of the switch base body 11. The spring 16 is attached to the inner bottom end of the switch base body 11. The spring 16 and the power-connecting pins 15 form an on / off control circuit. When the spring 16 is compressed and deformed, the two sets of power-connecting pins 15 can be connected. When the spring 16 is no longer compressed, the spring 16 returns to its shape, and the connection between the two sets of power-connecting pins 15 is disconnected.

[0035] The light-emitting component 2 includes LED beads 21 and LED bead pins 22;

[0036] The LED bead pins 22 are provided in two sets. The two sets of LED bead pins 22 are respectively connected to the electrodes of the LED bead 21. The two sets of LED bead pins 22 are connected to the on / off control circuit. By selecting different connection methods, it can be selected to be always on or to light up synchronously with the triggering of the switch base 1 and the press trigger component 3.

[0037] Both sets of LED bead pins 22 are L-shaped. The two sets of LED bead pins 22 are respectively inserted into the two sets of LED bead pin limiting parts 13 and are limited by the LED bead pin limiting parts 13. The LED bead pins 22 are supported by the top of the switch base body 11. Under the support of the switch base body 11, the setting position of the LED bead pins 22 remains unchanged, and the LED beads 21 connected to the LED bead pins 22 synchronously maintain the fixed setting position.

[0038] The opening position of the pressing relief groove 14 corresponds to the setting position of the buckle 45. The width of the pressing relief groove 14 is greater than the width of the buckle 45. When the buckle 45 is connected to the external equipment through the buckle, the buckle 45 can tilt and deform into the pressing relief groove 14. The pressing relief groove 14 provides sufficient deformation space for the buckle 45 to ensure that the buckle 45 is properly deformed and fastened to the outside.

[0039] The press trigger component 3 includes a button body 31, an LED lamp bead cavity 32, an LED bead pin clearance opening 33, and a press guide protrusion 34.

[0040] The button body 31 is fitted inside the key compartment 12. The LED lamp bead cavity 32 is opened at the center of the button body 31. The lamp bead pin clearance opening 33 is opened on both sides of the button body 31 at the corresponding positions of the LED lamp bead pins 22. The LED lamp bead pins 22 are simultaneously fitted into the lamp bead pin clearance opening 33. During the process of the button body 31 being pressed down, the button body 31 will not be linked with the LED lamp bead pins 22, so as not to affect the normal light emission of the LED lamp bead 21.

[0041] The pressing guide protrusion 34 is formed on the side of the button body 31. The pressing trigger component 3 also includes a pressing limit block 35, which is formed in the middle of the surface of the pressing guide protrusion 34. The inside of the switch base body 11 is provided with a slot that cooperates with the pressing limit block 35. The pressing limit block 35 is nested in the slot. The switch base body 11 limits the button body 31 through the cooperation of the slot and the pressing limit block 35. When the button body 31 is pressed, the button body 31 presses down the spring 16 to deform the spring 16. The deformed power pin 15 connects to the on / off control circuit to achieve trigger conduction. When the pressing of the button body 31 is released, the spring 16 returns to its shape. Under the elastic force of the spring 16, the button body 31 resets. The cooperation of the pressing limit block 35 and the slot limits the running distance of the button body 31 to prevent the button body 31 from coming out of the inside of the switch base body 11.

[0042] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
