Description

Technical Field

[0001] The utility model relates to the technical field of motion recognition, in particular to a highly sealed capacitor. Background Art

[0002] A capacitor is a basic electronic component in a circuit, mainly for energy storage and discharge. When working, when a voltage is applied across the capacitor, energy is input into one end of the capacitor and stored, and the other end of the capacitor releases energy. The energy stored in the capacitor is proportional to the square of the voltage. During continuous discharge, a part of the electric energy is always stored in the capacitor, so as to protect the circuit when the circuit is powered off.

[0003] The pins on the capacitor are welded to the circuit board. During use, the pins on the capacitor pass through the sealing gland of the capacitor itself and then connect to the circuit board. However, this will affect the sealing performance of the sealing gland of the capacitor itself, and the pins passing through the sealing gland of the capacitor are exposed outside, so it does not have sealing performance.

[0004] Therefore, how to provide a highly sealed capacitor is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0005] An object of the utility model is to provide a highly sealed capacitor. The utility model solves the problems that the pins of the existing capacitor passing through the sealing gland affect the sealing performance of the capacitor and the pins passing through the sealing gland are exposed outside and do not have sealing performance.

[0006] A highly sealed capacitor according to an embodiment of the utility model includes a capacitor body. A sealing ring is arranged at the bottom of the capacitor body. A plate-shaped sealing component is movably arranged inside the sealing ring. Pins are arranged at the bottom of the capacitor body and are located inside the sealing ring. The pins pass through the plate-shaped sealing component and extend to the lower part of the plate-shaped sealing component. A sealing tube is embedded at the position of the pins on the plate-shaped sealing component, and the sealing tube is movably sleeved on the surface of the pins.

[0007] The plate-shaped sealing component includes a sealing plate and a sealing side ring. The side surface of the sealing plate is movably arranged on the inner wall of the sealing ring. An insulating sealing layer plate is rotatably arranged on the sealing plate, and the sealing tube is embedded on the insulating sealing layer plate.

[0008] The sealing tube is an insulating rubber elastic sealing tube.

[0009] A pressing plate is arranged below the sealing side ring, and a sealing gasket is arranged on the lower surface of the pressing plate.

[0010] A buckle component is arranged on the side surface of the sealing plate, and a clamping groove is arranged at the corresponding position of the buckle component on the inner wall of the sealing ring. The buckle component is movably clamped inside the clamping groove.

[0011] The number of the buckle components is two groups, and the two groups of buckle components are arranged axially symmetrically with the vertical symmetry axis of the sealing plate as the axis of symmetry. The positions and numbers of the card slots match the buckle components. The buckle component includes a placement groove, a first spring member, and a movable clamping body. The placement groove is opened on the side of the sealing plate. The first spring member and the movable clamping body are movable inside the placement groove. One end of the first spring member close to the sealing ring is connected to the end of the movable clamping body far from the sealing ring. The other end of the movable clamping body passes through the placement groove and is clamped with the card slot.

[0012] The card slot is a "7"-shaped groove, and a limiting block is arranged on the inner wall of the card slot.

[0013] A second spring member sleeved on the surface of the pin is arranged on the upper surface of the sealing plate. The top end of the second spring member is arranged on the lower surface of the capacitor body.

[0014] The beneficial effects of the present utility model are as follows:

[0015] By providing a sealing ring and a plate-shaped sealing component, the sealing plate on the plate-shaped sealing member horizontally blocks the position of the pin and cooperates with the sealing ring to seal the position where the bottom of the capacitor body is penetrated by the pin. Then, a sealing tube is used to improve the sealing performance between the pin and the sealing plate. The sealing ring and the plate-shaped sealing component block the outside of the pin to shield the pin. Then, the bottom of the plate-shaped sealing component is attached to the surface of the circuit board through a pressing plate to cover the exposed pin to form a seal, thereby achieving the effect of improving the sealing performance of the capacitor body and the sealing performance of the pin position, and solving the problem that the existing capacitor pins penetrate the sealing gland, affecting the sealing performance of the capacitor, and at the same time, the pins exposed outside after passing through the sealing gland do not have sealing performance.

[0024] Embodiment 1

[0025] Reference Figure 1, including a capacitor body 1. A sealing ring 2 is provided at the bottom of the capacitor body 1. The sealing ring 2 is a cylindrical structure, which can cover the pins 4 of the capacitor body 1 and the positions penetrated by the pins 4. A plate-shaped sealing component 3 is movably arranged inside the sealing ring 2. The plate-shaped sealing component 3 includes a sealing plate member 6 and a sealing side ring 7. The sealing side ring 7 is also a cylindrical structure and is movable on the inner wall of the sealing ring 2 to adjust the height. The side surface of the sealing plate member 6 is movable on the inner wall of the sealing ring 2. The cooperation between the sealing plate member 6 and the sealing ring 2 seals the positions on the capacitor body 1 penetrated by the pins 4, thus increasing the sealing performance at this position. An insulating sealing layer plate 8 is rotatably arranged on the sealing plate member 6. The insulating sealing layer plate 8 is used to achieve an insulating effect and prevent short circuit between the two pins 4. A sealing tube 5 is embedded on the insulating sealing layer plate 8. The sealing side ring 7 can move on the sealing ring 2, which can drive the sealing plate member 6 and the pressure foot to move on the sealing ring 2 so that the connection between the pins 4 and the circuit board can be exposed and sealed. A pressing plate 9 is arranged below the sealing side ring 7. The pressing plate 9 increases the contact area pressing on the circuit board (which is an external component and the installation position of the capacitor body 1, not shown in the figure), thus increasing the sealing performance. To further increase the sealing performance, a sealing gasket 10 is arranged on the lower surface of the pressing plate 9. A sealing gasket 10 is also added below the pressing plate 9. The sealing gasket 10 is an annular sealing member, which increases the degree of fitting with the circuit board when pressing down. Pins 4 are provided at the bottom of the capacitor body 1. The pins 4 are located inside the sealing ring 2. After passing through the plate-shaped sealing component 3, the pins 4 extend below the plate-shaped sealing component 3. A sealing tube 5 is embedded at the position of the pins 4 on the plate-shaped sealing component 3. The sealing tube 5 is movably sleeved on the surface of the pins 4. The sealing tube 5 is an insulating rubber elastic sealing tube 5. The main function of the insulating rubber elastic sealing tube 5 is to reduce the gap between the sealing tube 5 and the pins 4 under its elastic action and enhance the sealing performance. During operation, first move the sealing plate member 6 and the sealing side ring 7 upward to drive the pressure foot to move upward to expose the pins 4. Then, after installing the pins 4 on the circuit board, move the sealing side ring 7 and the sealing plate member 6 downward to cover the pins 4. Then, the pressing plate 9 and the sealing gasket 10 are attached to the circuit board to achieve the effect of sealing the exposed position of the pressure foot.

[0026] Embodiment 2

[0027] The side of the sealing plate member 6 is provided with a buckle assembly 11 for stabilizing the sealing plate member 6. A clamping groove 12 is provided on the inner wall of the sealing ring 2 corresponding to the position of the buckle assembly 11. The clamping groove 12 is a "7"-shaped groove. In order to provide a movement range for the movable clamping body 15 and limit and guide the movable clamping body 15, a limiting block 16 is provided on the inner wall of the clamping groove 12. There are two limiting blocks 16 corresponding to each clamping groove 12. The clamping groove 12 has a horizontal section and a vertical section. The limiting block 16 is arranged at the bottom of the inner wall of the horizontal section of the clamping groove 12 for positioning the movable clamping body 15. The buckle assembly 11 is movably clamped inside the clamping groove 12. The number of the buckle assemblies 11 is two groups, and the two groups of buckle assemblies 11 are axially symmetrically arranged with the vertical symmetry axis of the sealing plate member 6 as the axis of symmetry. The position and number of the clamping grooves 12 match the buckle assembly 11. The buckle assembly 11 includes a placement groove 13, a first spring member 14 and a movable clamping body 15. The placement groove 13 is opened on the side of the sealing plate member 6. The first spring member 14 and the movable clamping body 15 are movably inside the placement groove 13. One end of the first spring member 14 close to the sealing ring 2 is connected to one end of the movable clamping body 15 away from the sealing ring 2. The other end of the movable clamping body 15 passes through the placement groove 13 and is clamped with the clamping groove 12. During operation, when the pin 4 needs to be exposed, the pressing plate 9, the sealing side ring 7 and the sealing plate member 6 are moved upward, so that the movable clamping body 15 is driven to move upward in the vertical section of the clamping groove 12. When the movable clamping body 15 reaches the entrance of the horizontal section of the clamping groove 12, the sealing side ring 7 and the sealing plate member 6 are rotated to drive the movable clamping body 15 to enter the horizontal section of the clamping groove 12 and be positioned by the limiting block 16. In this way, after the pressing plate 9 and the sealing side ring 7 are stabilized, the pin 4 is exposed. When the pin 4 needs to be sealed, the above reverse operation can be performed to cover and seal the pin 4.

[0028] Embodiment 3

[0029] The upper surface of the sealing plate member 6 is provided with a second spring member 17 sleeved on the surface of the pin 4. The top end of the second spring member 17 is arranged on the lower surface of the capacitor body 1. Under the action of the second spring member 17, the second spring member 17 will downwardly press the insulating sealing layer plate 8 to push the sealing plate and the sealing side ring 7 downward. The sealing side ring 7 will drive the pressing plate 9 and the sealing gasket 10 to stably press on the circuit board, improving the sealing performance and sealing stability of this position.
