Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum electrolytic capacitors, specifically a temperature-resistant and shock-resistant protective shell for aluminum electrolytic capacitors. Background Technology

[0002] With the rapid iteration of power electronics, new energy, and industrial control, higher requirements are being placed on the voltage tolerance, reliability, and integration of electronic components. Aluminum electrolytic capacitors are widely used in artificial intelligence, AI computing, new energy vehicles, 5G communication, battery energy storage, and chips. In some application scenarios, the ambient temperature exceeds 125 degrees Celsius, which places high demands on the temperature resistance of aluminum electrolytic capacitors. Ordinary aluminum electrolytic capacitors are insufficient to meet these requirements, necessitating protective casings to provide better temperature resistance. During the use of some electronic devices, such as those in automotive electronics and aerospace, vibration and impact are unavoidable. The electrode pins and other parts of aluminum electrolytic capacitors are prone to swaying and shaking under vibration and impact, leading to poor connections or even damage, affecting the normal operation of the equipment.

[0003] Meanwhile, the surface mount solid aluminum electrolytic capacitor with application number CN201921318089.0 includes a solid aluminum electrolytic capacitor body arranged horizontally, conductive posts disposed at both ends of the solid aluminum electrolytic capacitor body and electrically connected to the solid aluminum electrolytic capacitor body, a support frame disposed below the conductive posts and electrically connected to the conductive posts for supporting and mounting the solid aluminum electrolytic capacitor body, and a locking mechanism disposed at the free end of the conductive posts for axially locking the support frame. The support frame includes a connecting part sleeved on the conductive posts and a mounting part connected to the connecting part. The mounting part is arranged horizontally and has serrations on its lower surface.

[0004] However, the following problems were found in the implementation of the relevant technology: the patch and the electrolytic container are designed as one piece, which causes the adhesion of the electrolytic container to decrease after long-term storage and use, thereby affecting the stability of the entire device. At the same time, it cannot reduce the damage of high temperature, dust or moisture in the external environment to the electrolytic container.

[0005] Therefore, we propose a temperature-resistant and shock-resistant protective shell for aluminum electrolytic capacitors. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a temperature-resistant and shock-resistant protective shell for aluminum electrolytic capacitors. It has the advantages of preventing the degradation of patch adhesion due to long-term placement, maintaining initial adhesive strength and positioning accuracy, maintaining strong shock resistance, and reducing the transfer of heat, humidity and contamination.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a protective shell for a temperature-resistant and shock-resistant aluminum electrolytic capacitor, comprising a base, an aluminum electrolytic capacitor detachably connected inside the base, the leads of the aluminum electrolytic capacitor protruding from the bottom surface of the base, a rectangular groove provided inside the base, a long groove provided on the rear side of the rectangular groove, a fixing plate fixedly connected to the inner surface of the rectangular groove, a spring fixedly connected to the outer surface of the fixing plate, a locking block fixedly connected to the other end of the spring, an encapsulation patch provided on the bottom surface of the base, a locking groove provided on the encapsulation patch, several positioning holes provided on the base, a heat insulation cover detachably connected to the base, a positioning post fixedly connected to the lower surface of the heat insulation cover, a magnet fixedly connected to the positioning post and the positioning hole, ball grooves provided on both sides of the aluminum electrolytic capacitor, openings provided on both sides of the inner surface of the base, and spring ball bearings fixedly connected in the openings.

[0008] Preferably, the upper cross section of the card block is a hollow rectangle, and the spring is located inside the hollow part of the card block.

[0009] Preferably, the front side of the card block is sloping and rounded, and the rear side of the card block is provided with anti-slip texture.

[0010] Preferably, the positioning hole and the positioning post are provided with a sinking groove, the magnet is located in the sinking groove, and the positioning hole and the positioning post are movably connected.

[0011] Preferably, the card slot is movably connected to the card block.

[0012] Preferably, the spring ball is movably connected to the ball groove.

[0013] Preferably, heat dissipation holes are provided on the front and rear sides of the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the cooperation of a base, rectangular groove, elongated groove, fixing plate, spring, clip, slot, and encapsulation patch, designs the bottom encapsulation patch as a detachable structure. The patch is not installed when the capacitor leaves the factory, but is installed on-site or when needed. It can also be replaced after long-term use, avoiding the degradation of patch adhesion due to long-term storage, maintaining the initial adhesive strength and positioning accuracy. The effective combination of patch adhesion and lead wire soldering enhances the stability of the base and circuit board, improves the shock resistance of the capacitor, allows for patch replacement on-site, extends the overall service life, reduces process fluctuations caused by adhesion degradation, and improves the long-term stability of aluminum electrolytic capacitors under high temperature and thermal cycling conditions.

The sliding mechanism is located within the rectangular groove 3 and the elongated groove 4, and the sliding range is limited by the rectangular groove 3 and the elongated groove 4. The base 1 is provided with several positioning holes 7. A heat insulation cover 8 is detachably connected to the base 1. A positioning post 9 is fixedly connected to the lower surface of the heat insulation cover 8. A magnet block 10 is fixedly connected to the positioning post 9 and the positioning hole 7. Ball grooves 11 are provided on both sides of the aluminum electrolytic capacitor 2. A slot 12 is provided on the front side of the aluminum electrolytic capacitor 2. Openings 13 are provided on both sides of the inner surface of the base 1. Spring ball bearings 14 are fixedly connected in the openings 13.

[0025] Specifically, the upper cross section of the locking block 6 is a hollow rectangle, and the spring 51 is located inside the hollow part of the locking block 6, so that the spring 51 can apply elastic force to the locking block 6.

[0026] Furthermore, the front of the locking block 6 is slanted and rounded, and the rear of the locking block 6 is provided with anti-slip texture, which is used to pull the locking block 6 with a flathead wrench.

[0027] Furthermore, a recessed groove is provided inside the positioning hole 7 and the positioning post 9, and the magnet block 10 is located in the recessed groove. The positioning hole 7 and the positioning post 9 are movably connected to reduce space occupation.

[0028] It is worth noting that card slot 12 is movably connected to card block 6.

[0029] It is worth noting that the spring ball 14 is movably connected to the ball groove 11.

[0030] It is worth mentioning that the base 1 has heat dissipation holes on the front and back sides for heat dissipation.

[0031] It is worth emphasizing that aluminum electrolytic capacitor 2 is specifically a high-temperature resistant solid-state chip aluminum electrolytic capacitor.

[0032] Among them, the aluminum electrolytic capacitor 2 is prior art and will not be described in detail; at the same time, this utility model also includes a power supply, a controller, and a switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0033] Working principle: In use, first, the aluminum electrolytic capacitor 2 is installed in the base 1, so that the spring ball bearing 14 on the base 1 engages with the ball groove 11 on the aluminum electrolytic capacitor 2, thereby fixing the position of the aluminum electrolytic capacitor 2. Then, the encapsulation patch 15 is installed on the bottom of the base 1. The encapsulation patch 15 presses through the locking block 6 at the bottom of the base 1, so that the locking block 6 engages with the locking groove 12 on the aluminum electrolytic capacitor 2. The locking block 6 is engaged with the encapsulation patch 15 due to the elasticity of the spring 51, thereby fixing the position of the encapsulation patch 15. Then, the entire device is mounted on the equipment through the encapsulation patch 15. Then, insert the heat insulation cover 8 into the positioning hole 7 on the base 1 through the positioning post 9. Then, fix the position of the heat insulation cover 8 by magnetic attraction between the positioning hole 7 and the magnet block 10 on the positioning post 9. The heat insulation cover 8 protects 2. After long-term use or in high-temperature environment, after the adhesion of the encapsulation patch 15 decreases, pull the locking block 6 with a flathead wrench. The locking block 6 is pressed backward to squeeze the spring 51. The spring 51 is compressed by the pressure, so that the locking block 6 slides in the rectangular groove 3 and the long groove 4, so that the locking block 6 slides out of the slot 12. Then, remove the encapsulation patch 15 and install a new one.
