Description

Technical Field

[0001] The utility model relates to the technical field of light touch switches, in particular to a light touch switch that is firmly installed. Background Art

[0002] Tactile switches have the advantages of low contact resistance, precise operating force error, and diversified specifications. They are widely used in electronic equipment and white appliances such as audio-visual products, digital products, remote controls, communication products, home appliances, security products, toys, computer products, fitness equipment, medical equipment, banknote detectors, laser pointer buttons, etc. Traditional touch switches generally include a plastic base, a power insert injection-molded on the plastic base, an upper cover, and a touch handle. The power pins of the power insert extend downward from the bottom wall of the plastic base. Traditional touch switches will become skewed when subjected to external force after installation, resulting in poor installation security, which affects the normal use of the touch switch.

[0003] For example, a Chinese patent document discloses a tact switch that is easy to install (Announcement No.: CN214378131U). Although this patent can change the length of the limit rod extending out of the round hole by pulling the protrusion, after the terminal of the tact switch is installed, the limit rod can contact the adjacent components under the action of the spring, so that the tact switch is subjected to a fixed force. Therefore, the tact switch will not be easily distorted by external force, and the terminal will not be easily twisted off.

[0004] However, when the touch switch is installed, its limit rod needs to cooperate with specific adjacent components to achieve stable and firm support for the touch switch. The touch switch is generally soldered to the top of the circuit board through pins. Providing matching adjacent components above the circuit board not only hinders the soldering of the pins, but also easily blocks the connection of surrounding lines, resulting in low practicality.

[0005] Therefore, we propose a firmly mounted tactile switch. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art. At present, when a tactile switch is installed, its limit rod needs to cooperate with specific adjacent components to achieve stable and firm support for the tactile switch. The tactile switch is generally soldered to the top of the circuit board through pins. By providing matching adjacent components above the circuit board, not only the soldering of the pins is hindered, but also the connection of surrounding lines is easily blocked, resulting in low practicality.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0009] The other end of the movable screw is provided with a positioning support device, and the positioning support device includes a support block, and the upper surface of the support block is fixedly connected to the other end of the movable screw.

[0010] Preferably, a non-slip rubber pad is fixedly connected to the lower surface of the support block, and a rotation limiting groove is provided at one end of the movable screw.

[0011] Preferably, a rotation limiting rod is movably sleeved on the inner wall of the rotation limiting groove, and one end of the rotation limiting rod is fixedly connected to the inner top wall of the telescopic sleeve.

[0027] Example 1

[0028] like Figure 1-4 As shown, the utility model provides a technical solution: a firmly installed light touch switch, comprising a light touch switch body 1, a telescopic sleeve 2 is fixedly connected to the lower surface of the light touch switch body 1, an annular limiting groove 3 is provided on the lower surface of the telescopic sleeve 2, an arc-shaped limiting slider 4 distributed in an annular array is slidably connected to the inner wall of the annular limiting groove 3, a plurality of arc-shaped limiting sliders 4 are fixedly connected to the lower surfaces of the threaded ring 5, and the arc-shaped limiting slider 4 cooperates with the threaded ring 5 to perform positioning and rotation through the cooperation of the annular limiting groove 3, the upper surface of the threaded ring 5 contacts the lower surface of the telescopic sleeve 2, the inner wall of the threaded ring 5 is threadedly connected to a moving screw 6, and the outer surface of one end of the moving screw 6 is movably sleeved with the inner wall of the telescopic sleeve 2;

[0029] The other end of the moving screw rod 6 is provided with a positioning support device, and the positioning support device includes a support block 7 , and the upper surface of the support block 7 is fixedly connected to the other end of the moving screw rod 6 .

[0030] Example 2

[0031] like Figure 1-4 As shown, the utility model provides a technical solution: the lower surface of the support block 7 is fixedly connected with a non-slip rubber pad 71, and one end of the movable screw 6 is provided with a rotation limiting groove 72, and the non-slip rubber pad 71 plays a role in improving the supporting stability of the support block 7.

[0032] A rotation limiting rod 73 is movably sleeved on the inner wall of the rotation limiting groove 72. One end of the rotation limiting rod 73 is fixedly connected to the inner top wall of the telescopic sleeve 2. The cross-section of the rotation limiting rod 73 is rectangular, thereby cooperating with the rotation limiting groove 72 to limit the rotation.

[0033] The outer surface of the threaded ring 5 is fixedly connected to connecting rods 74 distributed in a ring array, and one end of the connecting rod 74 is fixedly connected to a rotating block 75. The rotating block 75 increases the contact area with the finger, thereby facilitating the rotation of the threaded ring 5 through the connecting rod 74.

[0034] The lower surface of the touch switch body 1 is fixedly connected to a symmetrically distributed guide rod 76, and the lower surface of the touch switch body 1 is provided with a symmetrically distributed pin 77. The guide rod 76 cooperates with the guide hole opened on the circuit board to perform preliminary positioning of the touch switch body 1, thereby facilitating stable welding of the pin 77.

[0035] A contact button 78 is provided on the upper surface of the touch switch body 1 , and a silicone pad 79 is fixedly connected to the upper surface of the contact button 78 . The silicone pad 79 serves to provide flexible protection for the contact button 78 .

[0036] The upper surface of the silicone pad 79 is fixedly connected with anti-skid bumps 710 distributed in a ring array. The anti-skid bumps 710 serve to increase friction when pressed.

[0037] Through the positioning support device, the touch switch body 1 is guided and positioned, thereby facilitating the stable welding of the pin 77, and the movement of the movable screw 6 drives the support block 7 to move and fit onto the circuit board, thereby providing stable support for the touch switch body 1, avoiding the pin 77 from being tilted, bent or even broken due to external forces, thereby improving the stability and firmness of the touch switch body 1 after installation.

[0038] The working process of this utility model:

[0039] Step 1: During installation, the guide rod 76 is aligned with the guide hole on the circuit board and inserted to guide and position the touch switch body 1, which facilitates the subsequent stable welding of the pin 77. After welding, the rotation block 75 and the connecting rod 74 cooperate to drive the threaded ring 5 to rotate clockwise. The rotation of the threaded ring 5 is positioned and rotated by the cooperation between the annular limiting groove 3 and the arc-shaped limiting slider 4;

[0040] In step 2, the positioning rotation of the threaded ring 5 is limited by the rotation limit groove 72 and the rotation limit rod 73, so that it drives the movable screw 6 to move downward. The downward movement of the movable screw 6 drives the support block 7 to move downward. When the support block 7 drives the anti-slip rubber pad 71 to move to contact with the circuit board, it stops rotating. At this time, the touch switch body 1 is stably supported by the support block 7, and the guide rod 76 is limited to cooperate, thereby avoiding the situation where the pin 77 of the touch switch body 1 is tilted, bent or even broken when the touch switch body 1 is impacted by external force.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
