Description

Technical Field

[0001] The utility model relates to the technical field of tantalum capacitors, in particular to a shell cover structure with good sealing performance. Background Art

[0002] Tantalum capacitors generally refer to tantalum electrolytic capacitors. Solid tantalum capacitors were first developed by Bell Laboratories in the United States in 1956. They offer excellent performance, achieving the highest capacitance in a small package. Tantalum capacitors come in a variety of shapes and are easily manufactured into small, surface-mountable components.

[0003] In the prior art, the shell and shell cover of tantalum capacitors are both made of pure tantalum. The tantalum wire on the shell cover is connected to the shell to form an electrical connection with the outside. During use, the shell cover is usually directly pressed into the shell, which makes it difficult to remove and replace the shell cover, which is inconvenient to use. To this end, we have proposed a shell cover structure with good sealing performance to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the present invention is to provide a shell cover structure with good sealing performance to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a shell cover structure with good sealing performance, comprising:

[0006] The shell cover body has two connecting blocks fixedly bonded on the bottom wall of the shell cover body, connecting rods are fixedly welded on the two connecting blocks, a fixed block is fixedly welded on the top of the connecting rod, a clamping block is fixedly welded on the inner wall of the fixed block, a tantalum wire is fixedly installed in the middle of the shell cover body, an annular groove is provided on the outer wall of the shell cover body, a sealing ring is installed in the annular groove, and a liquid injection hole is provided on the shell cover body.

[0007] Preferably, the connecting rod is made of steel.

[0008] Preferably, the top side wall of the block is arranged to be inclined.

[0009] Preferably, the top wall and the bottom wall of the sealing ring are both arranged to be inclined.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The shell cover body of the utility model cooperates with the provided connecting block, connecting rod, fixing block and clamping block, so that when the shell cover body is installed, the fixing block can be tightly pressed against the outer wall of the shell of the tantalum capacitor through the bending elasticity of the connecting rod, thereby ensuring the firmness of the shell cover body installed on the shell of the tantalum capacitor. At the same time, when disassembling, the shell cover body can be removed by simply depressing the two fixing blocks outward, making the shell cover body more convenient to disassemble. The provided sealing ring can improve the sealing performance of the connection between the shell cover body and the shell of the tantalum capacitor to avoid leakage.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-3 The utility model provides a technical solution: a shell cover structure with good sealing performance, comprising:

[0018] The shell cover body 1 has two connecting blocks 2 fixedly bonded to the bottom wall of the shell cover body 1, and a connecting rod 3 is fixedly welded to each of the two connecting blocks 2. A fixing block 4 is fixedly welded to the top of the connecting rod 3, and a clamping block 5 is fixedly welded to the inner wall of the fixing block 4. A tantalum wire 6 is fixedly installed in the middle of the shell cover body 1, and an annular groove 7 is provided on the outer wall of the shell cover body 1. A sealing ring 8 is installed in the annular groove 7, and an injection hole 9 is provided on the shell cover body 1.

[0019] The connecting rod 3 is made of steel material, which has good bending elasticity, so that the connecting rod 3 can give good elastic pressure to the fixing block 4 after bending.

[0020] The top side wall of the clamping block 5 is arranged to be inclined, so that the clamping block 5 can more easily slide into the shell surface of the tantalum capacitor when the shell cover body 1 is installed.

[0021] The top wall and the bottom wall of the sealing ring 8 are both arranged to be inclined, so that the sealing ring 8 can more easily slide into the inner wall of the shell of the tantalum capacitor when the shell cover body 1 is installed.

[0022] Working principle: When installing this utility model, first align the shell cover body 1 with the shell opening of the tantalum capacitor, and then press the shell cover body 1 upward to make the shell cover body 1 move upward into the shell of the tantalum capacitor. During this process, the two clamping blocks 5 of the shell cover body 1 slide on the outer wall of the shell of the tantalum capacitor until they are inserted into the clamping groove of the shell of the tantalum capacitor. At the same time, the elastic force generated by the bending of the steel connecting rod 3 acts on the fixing block 4, so that the two fixing blocks 4 can be tightly pressed on the outer wall of the shell of the tantalum capacitor, thereby fixing the shell cover body 1 on the shell of the tantalum capacitor. When disassembling, you only need to push the two fixing blocks 4 outward to remove the shell cover body 1. The provided sealing ring 8 can improve the sealing of the connection between the shell cover body 1 and the shell of the tantalum capacitor to avoid leakage.
