Abstract
Description
Technical Field
[0001] The utility model relates to the field of capacitors, in particular to an anti-interference capacitor. Background Technique
[0002] A capacitor is a device that can store electric charge. It is composed of two conductors close to each other with a layer of non-conductive insulating medium in between. Generally, its ability to store electric charge is called capacitance, which is represented by the letter C. Capacitors are one of the most widely used electronic components in electronic devices, and are widely used in aspects such as DC blocking and AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, and control in circuits.
[0003] During the use of capacitors, they are vulnerable to external interference, which may cause damage to the capacitors. Therefore, anti-interference packaging shells are often installed on the capacitors. Most of the existing anti-interference packaging shells are connected by welding. Once the capacitors need to be repaired during use, due to the welding connection of their anti-interference packaging shells, it is extremely inconvenient to disassemble and assemble them during maintenance.
[0004] There is a need to develop an anti-interference capacitor with a conveniently disassembled and assembled anti-interference packaging shell. Content of the Utility Model
[0005] In order to overcome the disadvantage that the anti-interference packaging shell is not easy to disassemble and assemble, the utility model provides an anti-interference capacitor with a conveniently disassembled and assembled anti-interference packaging shell.
[0006] To solve the above technical problems, the utility model provides such an anti-interference capacitor, which includes a capacitor body, pins, an anti-interference protection shell, a positioning plate, a mounting block, a first clamping block, a second clamping block, a guide rod, and a first spring. The anti-interference protection shell houses the capacitor body. Pins are installed on both the left and right sides of the bottom of the capacitor body. The anti-interference protection shell is divided into a front part and a rear part. Positioning plates are installed on the lower left and right sides of the front anti-interference protection shell. A mounting block is installed on the right side of the rear anti-interference protection shell. A first clamping block is installed on the right side of the front anti-interference protection shell. A second clamping block is slidably connected to the mounting block. Guide rods are installed on both the upper and lower sides of the left part of the second clamping block. A first spring is sleeved on the guide rod, and the two ends of the first spring are respectively connected to the mounting block and the second clamping block.
[0007] Preferably, heat dissipation holes are provided on the outer sides of both anti-interference protection shells.
[0008] Preferably, it further includes heat dissipation fins, and heat dissipation fins are installed on the top of the capacitor body.
[0009] Preferably, it further includes fixing blocks, second springs and clamping blocks. Fixing blocks are installed inside both of the two anti-interference protection cases. Clamping blocks are installed at one ends of the two fixing blocks away from the anti-interference protection cases. Two second springs are installed inside each of the two fixing blocks. Both ends of the four second springs are respectively connected to the fixing blocks and the clamping blocks.
[0010] Preferably, it further includes rubber plates. Rubber plates are installed at one ends of the two clamping blocks away from the second springs.
[0011] Preferably, the first clamping block is provided with a groove, which can cooperate with the second clamping block to close the two anti-interference protection cases.
[0012] The beneficial effects of the present utility model are as follows: 1. By inserting the second clamping block on the anti-interference protection case into the groove of the first clamping block installed on another anti-interference protection case, the two parts of the anti-interference protection case can be locked. When it is necessary to open the anti-interference protection case, pull the second clamping block to move outwards. When the second clamping block leaves the groove of the first clamping block, the two anti-interference protection cases can be opened, achieving the effect of facilitating the disassembly of the anti-interference protection case.
[0013] 2. By compressing the second spring with the capacitor contacting the clamping block, and then closing the two parts of the anti-interference protection case after the second spring resets to drive the clamping block to clamp the capacitor, the effect of fixing the capacitor to prevent the capacitor from shifting is achieved.

Detailed Embodiments
[0020] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] Embodiment 1
[0022] An anti-interference capacitor, as Figures 1 - 5 shown, includes a capacitor body 1, pins 2, an anti-interference protective shell 3, a positioning plate 5, a mounting block 6, a first clamping block 7, a second clamping block 8, a guide rod 9, and a first spring 10. The anti-interference protective shell 3 houses the capacitor body 1 inside. Pins 2 are installed on both the left and right sides of the bottom of the capacitor body. The anti-interference protective shell 3 is divided into front and rear parts. Positioning plates 5 are installed below the left and right sides of the front anti-interference protective shell 3. A mounting block 6 is installed on the right side of the rear anti-interference protective shell 3. A first clamping block 7 is installed on the right side of the front anti-interference protective shell 3. A second clamping block 8 is slidably connected to the mounting block 6. The first clamping block 7 is provided with a groove, which can cooperate with the second clamping block 8 to close the two anti-interference protective shells 3. Guide rods 9 are installed on both the upper and lower sides of the left part of the second clamping block 8. A first spring 10 is sleeved on the guide rods 9. The two ends of the first spring 10 are respectively connected to the mounting block 6 and the second clamping block 8.
[0023] When workers use the capacitor for work, the capacitor is prone to being damaged by external interference during use. Therefore, a protective shell that is convenient to disassemble needs to be installed on the capacitor to prevent the capacitor from being interfered by the outside world during work. Therefore, this device needs to be used to protect the capacitor. When this device needs to be used, first pull the second clamping block 8 outward. The second clamping block 8 leaves the groove of the first clamping block 7, and the two anti-interference protective shells 3 can be opened. Put the capacitor in, fix the capacitor, then close the two parts of the anti-interference protective shell 3, and then insert the second clamping block 8 into the groove of the first clamping block 7 to complete the closing.
[0024] Embodiment 2
[0025] On the basis of Embodiment 1, as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, it further includes heat dissipation holes 4, heat dissipation fins 11, fixing blocks 12, second springs 13, clamping blocks 14, and rubber plates 15. Heat dissipation holes 4 are opened on the outer sides of the two anti-interference protective shells 3. Heat dissipation fins 11 are installed on the top of the capacitor body 1. Fixing blocks 12 are installed inside the two anti-interference protective shells 3. Clamping blocks 14 are installed at the ends of the two fixing blocks 12 away from the anti-interference protective shells 3. Two second springs 13 are installed inside the two fixing blocks 12. The two ends of the second springs 13 are respectively connected to the fixing blocks 12 and the clamping blocks 14. The contraction of the second springs 13 causes the clamping blocks 14 to clamp the capacitor to prevent displacement. Rubber plates 15 are installed at the ends of the clamping blocks 14 away from the second springs 13.
[0026] To prevent the capacitor from shifting, place the capacitor. The capacitor squeezes the clamping plates on both sides respectively, compressing the four second springs 13 on the front and rear sides. The reset of the second springs 13 resets the clamping blocks 14 on the front and rear sides to fix the capacitor, and then close the anti-interference protective case 3.
