Description

Technical Field

[0001] The utility model belongs to the technical field of potentiometer installation, in particular to a fixing component for installing a potentiometer. Background Art

[0002] A potentiometer is an adjustable resistor consisting of a resistor, a brush, and a slider. By rotating or sliding the brush, the contact position between the slider and the resistor can be changed, thereby changing the resistance of the resistor. The working principle of the potentiometer is to adjust the resistance value by changing the contact length at both ends of the resistor. The potentiometer usually consists of a rotating slider, which is connected to a linear or annular resistor. When the knob is adjusted, the position of the slider's contact point relative to the resistor will change, thereby changing the resistance value. By changing the resistance value of the potentiometer, the voltage in the circuit can be adjusted. For example, in audio equipment, the potentiometer can be used to adjust the volume.

[0003] However, the above device still has the following problems during implementation:

[0004] The existing technology generally makes it possible to directly insert the potentiometer into the printed circuit board and perform wave soldering. When installing the potentiometer, it is necessary to use a welding gun for welding. During the welding process, accidental injury may occur due to the high temperature of the welding gun. In addition, toxic gases may be generated during the welding process, which may easily cause harm to the workers. Therefore, a fixing assembly for installing the potentiometer is specially proposed to solve the above problems. Utility Model Content

[0023] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, an embodiment of the present invention provides a fixing assembly for installing a potentiometer, comprising a connector 1, a potentiometer device 2, and three lugs 3. The top of the connector 1 is movably connected to the bottom of the potentiometer device 2, and the lugs 3 are welded to the top of the potentiometer device 2.

[0026] The fixing component 6 is used to fix the position of the potential device 2 , and the fixing component 6 is arranged in the inner cavity of the installation groove 4 .

[0027] refer to Figure 2 and Figure 3 The top of the connector 1 is provided with a docking slot 7 for use with the potential device 2. The potential device 2 is plugged into the inner cavity of the docking slot 7. The front and rear sides of the potential device 2 are provided with card slots 8.

[0028] By adopting the above solution, by providing the docking groove 7 and the clamping groove 8, after the potential device 2 is inserted into the connector 1, the docking groove 7 can position the potential device 2, and the clamping groove 8 is aligned with the clamping block 62, which can facilitate insertion and fixation.

[0029] refer to Figure 3 The fixing assembly 6 includes two movable plates 61, and the opposite sides of the two movable plates 61 are fixedly connected with a card block 62 used in conjunction with the card slot 8. The side of the card block 62 away from the movable plate 61 passes through the installation slot 4 and extends to the inner cavity of the card slot 8. The opposite sides of the two movable plates 61 are fixedly connected with a spring 63.

[0030] The above solution is adopted: by setting a fixing component 6, after the card block 62 is inserted into the card slot 8, the pressure of the movable plate 61 is exerted by the spring 63, so that after the movable plate 61 drives the card block 62 to be inserted into the card slot 8, the card block 62 will not be detached.

[0031] refer to Figure 3 A control hole 9 is provided on the front and rear sides of the mounting groove 4 , and a control rod 10 is plugged into the inner cavity of the control hole 9 . The side of the control rod 10 close to the movable plate 61 is fixedly connected to the movable plate 61 .

[0032] Adopting the above solution: by setting the control hole 9 and the control rod 10, when the movable plate 61 moves the compression spring 63, the control rod 10 and the control hole 9 can control the moving position of the movable plate 61, so that the movable plate 61 will not shake when moving.

[0033] refer to Figure 3 The left side of the pulling member 5 is fixedly connected to a linkage plate 11, and the front and rear sides of the bottom of the linkage plate 11 are rotatably connected to a first extrusion rod 12 through a rotating shaft. The side of the first extrusion rod 12 close to the movable plate 61 is rotatably connected to the movable plate 61 through a rotating shaft.

[0034] The above solution is adopted: by setting the linkage plate 11 and the first extrusion rod 12, when the pulling member 5 is pulled to drive the linkage plate 11 to move, the two first extrusion rods 12 can squeeze the two moving plates 61, so that the two blocking blocks 62 can be driven to disengage at the same time.

[0035] refer to Figure 4The front and rear sides of the right side of the linkage plate 11 are both rotatably connected to the second extrusion rod 13 through a rotating shaft, and the top of the second extrusion rod 13 is rotatably connected to the push rod 14 through a rotating shaft.

[0036] Adopting the above solution: by setting the second extrusion rod 13 and the push rod 14, when the linkage plate 11 moves, it can drive the second extrusion rod 13 to squeeze the push rod 14, so that the push rod 14 can rise and drive the anti-slip plate 15 to move to a suitable position.

[0037] refer to Figure 4 The top of the push rod 14 passes through the accommodating groove and is fixedly connected to the anti-slip plate 15, and the bottom of the anti-slip plate 15 is in contact with the wiring piece 3.

[0038] With the above solution, by providing the anti-slip plate 15 , after the terminal piece 3 is connected to the circuit, the anti-slip plate 15 presses down and compacts the circuit, so that the circuit on the terminal piece 3 is not easily detached due to external force.

[0039] The working principle of this utility model:

[0040] When in use, first use a small screw to install the connector 1 at the position where the potentiometer needs to be installed, then use an electric wire to connect the terminal piece 3 on the potential device 2, and then pull the pulling piece 5 to drive the linkage plate 11 to move. The movement of the linkage plate 11 will drive the first extrusion rod 12 to squeeze the two moving plates 61 away from each other. The movement of the moving plate 61 squeezes the spring 63 to drive the block 62 to move to the appropriate position, and the movement of the linkage plate 11 will drive the second extrusion rod 13 to squeeze the push rod 14 to rise. The rise of the push rod 14 will drive the anti-slip plate 15 to rise. Then the bottom of the potential device 2 is flush with the top of the connector 1, and then the potential device 2 is pushed to the left so that the bottom of the terminal piece 3 contacts the anti-slip plate 15, and then the potential device 2 can be pressed down to insert it into the docking groove 7. At this time, the pulling piece 5 can be released, and the elastic deformation of the spring 63 will drive the movable plate 61 back to its original position. The movement of the movable plate 61 will drive the card block 62 to pass through the installation slot 4 to the card slot 8. At this time, the linkage plate 11 will also drive the second extrusion rod 13 and the push rod 14 to descend, and the push rod 14 will drive the anti-slip plate 15 to press the terminal piece 3.

[0041] To sum up: the fixing component 6 installed in the potentiometer is used in conjunction with the terminal piece 3, the mounting groove 4, the pulling piece 5 and the fixing component 6. Then the potential device 2 can be pressed down and inserted into the docking groove 7. At this time, the pulling piece 5 can be released, and the elastic deformation of the spring 63 will drive the movable plate 61 back to its original position. The movement of the movable plate 61 will drive the clamping block 62 to pass through the mounting groove 4 to the clamping groove 8, which solves the problem that the potentiometer needs to be welded with the help of a welding gun during installation. During the welding process, accidental injury is easy to occur due to the high temperature of the welding gun, and toxic gas is also generated during the welding process, which is easy to cause harm to the workers.
