DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , a fixing device for a capacitor, comprising a base 1. Vertical plates 2 are fixedly installed at the top of both the left and right sides of the base 1. A guiding groove 3 is formed through the side surface of the upper half of the vertical plate 2. A pressing plate 4 is arranged between the two groups of vertical plates 2. Limiting components 5 are arranged in the middle of both the left and right sides of the pressing plate 4. The limiting components 5 are slidably connected through the guiding groove 3. Two groups of mounting grooves 6 are formed through the surface of the pressing plate 4. Sliding grooves 7 are formed on both the left and right side walls of the pressing plate 4 at the mounting grooves 6. Two groups of connecting components 8 are slidably connected in each group of mounting grooves 6. Clamping components 9 are arranged on both the front and rear sides of the pressing plate 4.

[0026] Please refer to Figure 2 , the limiting component 5 includes sliders 51 fixedly installed in the middle of both the left and right sides of the pressing plate 4. The sliders 51 are slidably connected in the guiding groove 3. Two groups of bosses 41 distributed front and rear are fixedly installed on both the left and right sides of the pressing plate 4. The two groups of bosses 41 are respectively clamped on the front and rear sides of the vertical plate 2. The pressing plate 4 is stably slidably connected between the two groups of vertical plates 2, so that the height of the pressing plate 4 can be adjusted to meet the fixing requirements of capacitors with different lengths. Hinge arms 52 are hinged on both sides of the other end of the slider 51. A clamping plate 53 is fixedly installed at the other end of the hinge arm 52. Rubber strips 54 are fixedly installed on both the front and rear sides of the clamping plate 53. The rubber strips 54 are attached to the side wall of the guiding groove 3. The width of the clamping plate 53 is equal to the distance between the two side walls of the guiding groove 3. The cross section of the rubber strip 54 is semicircular. A mounting hole 55 is formed through the center of the clamping plate 53. The mounting hole 55 is used for inserting a bolt. Thus, during the deflection of the assembly of the hinge arm 52 and the clamping plate 53 relative to the slider 51, the clamping plate 53 can be deflected into the guiding groove 3, and the rubber strip 54 is pressed against the side wall of the guiding groove 3, so that the clamping plate 53 is clamped inside the guiding groove 3, thereby limiting the pressing plate 4. Through the setting of the mounting hole 55, a bolt can be inserted, and then cooperated with a nut to fix the clamping plate 53 on the vertical plate 2, further ensuring the fixing effect between the clamping plate 53 and the vertical plate 2.

[0027] Please refer to Figure 3, the connecting component 8 includes a support plate 81 slidably connected in the installation groove 6. At both ends of the support plate 81, insertion blocks 82 are fixedly installed. The insertion blocks 82 are slidably connected in the sliding grooves 7. Through the cooperation of the insertion blocks 82 and the sliding grooves 7, the support plate 81 is stably slidably connected in the installation groove 6. At the top of the support plate 81, a touch plate 83 is fixedly installed. At both ends of the touch plate 83, connecting heads 84 are fixedly installed. A plurality of jacks 85 are penetrated through the surfaces of the support plate 81 and the touch plate 83. Through the arrangement of the jacks 85, it is convenient for the pins of the capacitor to be inserted and connected to the touch plate 83. Then, they are uniformly connected to the external circuit through the connecting heads 84. At the top of the touch plate 83, an L-shaped piece 86 is fixedly installed. The L-shaped pieces 86 correspond to the jacks 85 one by one. The horizontal part of the L-shaped piece 86 is located directly above the jack 85. Thus, by the pins of the capacitor abutting against the horizontal part of the L-shaped piece 86, the pins of the capacitor are stably connected to the touch plate 83. The connecting component 8 further includes partition plates 87 fixedly installed on the opposite sides of two groups of support plates 81 inside each installation groove 6. The partition plates 87 extend to the upper side of the touch plate 83. The adjacent two touch plates 83 are spaced apart by the partition plates 87 for insulation.

[0028] Please refer to Figure 4 , the clamping component 9 includes sliding rods 91 fixedly installed on the front and rear sides of the pressing plate 4. Two groups of sliding rods 91 are fixedly installed on the front and rear sides of the pressing plate 4. A clamping plate 92 is slidably connected to the surface of the sliding rod 91. The sliding rod 91 penetrates through the clamping plate 92. On the side of the clamping plate 92 away from the pressing plate 4, a spring 93 is fixedly installed. The other end of the spring 93 is fixedly installed with a gasket 94. The gasket 94 is sleeved on the outer side of the sliding rod 91. A limiting piece 95 is fixedly installed at the end of the sliding rod 91 away from the pressing plate 4. The gasket 94 abuts against the side of the limiting piece 95 close to the pressing plate 4. Due to the elasticity of the spring 93, the clamping plate 92 has a tendency to move towards the pressing plate 4, so that the clamping plate 92 presses against the side of the capacitor to limit the capacitor.

[0029] Working principle: Place the capacitor on the top of the base 1 with the pins facing upwards; push the support plate 81 to slide in the installation groove 6 so that the jacks 85 are opposite to the pins of the capacitor; then push the pressing plate 4 to move downwards so that the pins of the capacitor are inserted into the jacks 85 and abut against the L-shaped pieces 86, making the pins of the capacitor abut against the L-shaped pieces 86;

[0030] Then push the buckle plate 53 to deflect towards the vertical plate 2 so that the buckle plate 53 is snapped into the guiding groove 3, and the rubber strip 54 is pressed against the side wall of the guiding groove 3, so that the buckle plate 53 is stably arranged in the vertical plate 2; in addition, a bolt can be inserted into the installation hole 55, and then the bolt is screwed from the inner side of the vertical plate 2 onto the bolt to further fix the buckle plate 53 in the vertical plate 2, thereby limiting the pressing plate 4.

[0031] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
