The present invention provides a tantalum capacitor housing 10. The tantalum capacitor housing 10 includes a tantalum shell 100 and a tantalum cover 200. The tantalum shell 100 has an accommodating space 110, and the accommodating space 110 is used for storage. Electrolyte and electrode plate, a circular opening 120 is provided on the top of the tantalum shell 100, an internal thread 121 is provided on the inner surface of the circular opening 120, and pits are etched on the internal thread 121; the tantalum cover 200 includes a cover plate 210 and a pull rod. 220. The edge of the cover plate 210 is provided with external threads 211, and pits are etched on the external threads 211. The cover plate 210 is inserted into the circular opening 120 and is threadedly connected to the inner surface of the circular opening 120. The cover plate 210 faces away from One side of the accommodation space 110 is connected to the tie rod 220 .
上述钽电容器外壳10，通过使盖板210与钽壳100的圆形开口120螺纹连接，圆形开口120上内螺纹121与盖板210上外螺纹211的配合延长了电解液运动的路径，并对电解液进行封堵；在钽电容器的使用过程中，灰尘易积聚在内螺纹121与外螺纹211之间的缝隙，进一步阻断了电解液的渗漏途径；此外，通过分别在内螺纹121上及外螺纹211上蚀刻坑点，增大了盖板210与圆形开口120内表面的接触面积，进一步提高了钽电容器外壳10的密封性能，保证了钽电容器的输出的电压电流信号的稳定性，提升了钽电容器的可靠性；同时还消除了电解液渗漏对环境造成污染的可能，提升了钽电容器使用的安全性及环保性，并有利于延长外延设备的使用寿命。The above-mentioned tantalum capacitor shell 10 is threadedly connected to the circular opening 120 of the tantalum shell 100 by connecting the cover plate 210 to the circular opening 120. The cooperation between the internal threads 121 on the circular opening 120 and the external threads 211 on the cover plate 210 extends the path of the electrolyte movement, and The electrolyte is blocked; during the use of tantalum capacitors, dust easily accumulates in the gap between the internal thread 121 and the external thread 211, further blocking the leakage path of the electrolyte; in addition, through the internal threads 121 respectively Etching pits on the upper and outer threads 211 increases the contact area between the cover plate 210 and the inner surface of the circular opening 120, further improving the sealing performance of the tantalum capacitor shell 10 and ensuring the stability of the voltage and current signals output by the tantalum capacitor. It improves the reliability of tantalum capacitors; it also eliminates the possibility of environmental pollution caused by electrolyte leakage, improves the safety and environmental protection of tantalum capacitors, and helps extend the service life of epitaxial equipment.
钽壳100用于收容电解液及电极板，并为电解液在电极板之间的充电过程和放电过程提供反应场所。需要说明的是，钽壳100的容置空间110的大小直接决定了其可收容的电解液的量，也就是说，容置空间110的大小决定了钽电容器的电容量及其充放电能力的高低，进而决定了钽电容器的质量。一实施例中，钽壳100呈正方体结构。另一实施例中，钽壳100呈圆柱体结构。在实际生产中，还可根据生产条件及产品的结构要求，将钽壳100设计为多棱柱结构，于此不再赘述。The tantalum shell 100 is used to accommodate the electrolyte and the electrode plates, and provides a reaction place for the charging and discharging processes of the electrolyte between the electrode plates. It should be noted that the size of the accommodation space 110 of the tantalum shell 100 directly determines the amount of electrolyte it can accommodate. That is to say, the size of the accommodation space 110 determines the capacitance of the tantalum capacitor and its charge and discharge capabilities. The level determines the quality of tantalum capacitors. In one embodiment, the tantalum shell 100 has a cube structure. In another embodiment, the tantalum shell 100 has a cylindrical structure. In actual production, the tantalum shell 100 can also be designed as a polygonal prism structure according to production conditions and product structural requirements, which will not be described again here.
一实施例中，内螺纹121的圈数及外螺纹211的圈数分别大于3。优选的，内螺纹121的圈数与外螺纹211的圈数分别为5。可以理解为，盖板210通过多圈螺纹与钽壳100的圆形开口120螺接，如此，可进一步延长电解液向外渗漏时路径，增大电解液渗漏的难度，从而提高钽电容器外壳的密封性能。一实施例中，内螺纹121的工作高度大于10毫米。优选的，内螺纹121的工作高度为15毫米。这样一来，增大了内螺纹121齿顶与齿底之间的距离，进一步延长了电解液向外渗漏时的运动路径，从而进一步提升了钽电容器外壳的密封性。In one embodiment, the number of turns of the internal thread 121 and the number of turns of the external thread 211 are greater than 3 respectively. Preferably, the number of turns of the internal thread 121 and the number of turns of the external thread 211 are 5 respectively. It can be understood that the cover plate 210 is screwed to the circular opening 120 of the tantalum shell 100 through multiple turns of threads. In this way, the path when the electrolyte leaks out can be further extended, increasing the difficulty of electrolyte leakage, thereby improving the performance of the tantalum capacitor. The sealing performance of the shell. In one embodiment, the working height of the internal thread 121 is greater than 10 mm. Preferably, the working height of the internal thread 121 is 15 mm. In this way, the distance between the tooth top and the tooth bottom of the internal thread 121 is increased, further extending the movement path when the electrolyte leaks outward, thereby further improving the sealing performance of the tantalum capacitor shell.
需要说明的是，本发明的内螺纹121上的坑点及外螺纹211上的坑点均由浓度为40％的氢氧化钠溶液分别对内螺纹121及外螺纹211进行腐蚀形成，氢氧化钠对钽板的腐蚀性较强，可除去钽板表面的氧化保护层，并与钽单质发生反应，以消耗钽板上的钽材，从而形成凹凸不平的坑点，以利于增大盖板210与圆形开口120内表面之间的接触面积，提升钽电容器外壳的密封性能。It should be noted that the pits on the internal thread 121 and the pits on the external thread 211 of the present invention are formed by corrosion of the internal thread 121 and the external thread 211 respectively with a sodium hydroxide solution with a concentration of 40%. Sodium hydroxide It is highly corrosive to the tantalum plate, which can remove the oxidation protective layer on the surface of the tantalum plate and react with the tantalum element to consume the tantalum material on the tantalum plate, thereby forming uneven pits to facilitate the enlargement of the cover plate 210 The contact area with the inner surface of the circular opening 120 improves the sealing performance of the tantalum capacitor casing.
一实施例中，钽电容器外壳还包括密封环300，密封环300的外表面开设有螺纹卡槽310，内螺纹121卡设于螺纹卡槽310并与密封环300相抵接。可以理解为，密封环300填充了内螺纹121与外螺纹211之间的缝隙，从而阻断了电解液的渗漏路径，这样一来，钽电容器外壳的密封性能大大提升，保证了钽电容器输出电流及输出电压的稳定性。一实施例中，密封环300的材质为聚乙烯塑料。聚乙烯塑料的加工性能较好，其弹性较大，可对内螺纹121与外螺纹211之间的缝隙进行全面填充，且聚乙烯塑料的耐腐蚀性较好，在与电解液接触后不易老化变形，可持续对内螺纹121与外螺纹211之间的缝隙进行封堵，以保证钽电容器外壳的密封性。In one embodiment, the tantalum capacitor casing further includes a sealing ring 300 . A threaded groove 310 is provided on the outer surface of the sealing ring 300 . The internal thread 121 is engaged in the threaded groove 310 and abuts against the sealing ring 300 . It can be understood that the sealing ring 300 fills the gap between the internal thread 121 and the external thread 211, thereby blocking the leakage path of the electrolyte. In this way, the sealing performance of the tantalum capacitor shell is greatly improved, ensuring the output of the tantalum capacitor. Current and output voltage stability. In one embodiment, the sealing ring 300 is made of polyethylene plastic. Polyethylene plastic has better processing performance and greater elasticity. It can fully fill the gap between the internal thread 121 and the external thread 211. Moreover, polyethylene plastic has good corrosion resistance and is not easy to age after contact with the electrolyte. deformation, and continuously seal the gap between the internal thread 121 and the external thread 211 to ensure the sealing of the tantalum capacitor shell.
钽盖200用于封堵钽壳100的圆形开口120，以实现电解液及电极板在容置空间110内的封装，并保证钽电容器的密封性。具体的，在电解液及电极板的封装过程中，旋动钽盖200，将钽盖200从圆形开口120处取下，并将电解液及电解板依序安装至容置空间110内的指定部位，随后将钽盖200插设于圆形开口120并逐渐旋紧钽盖200，使钽盖200的外螺纹211与圆形开口120的内螺纹121螺合锁紧，即实现钽壳100的密封作业。请参阅图3，一实施例中，盖板210背向容置空间110的一面还设置有防漏胶环212，防漏胶环212与圆形开口120的外边缘相抵接。通过在盖板210上设置防漏胶环212，可进一步对内螺纹121与外螺纹211之间的缝隙进行封堵，防止电解液渗漏至环境中，进而造成的钽电容器的外延设备腐蚀的问题，以提升钽电容器使用的安全性及环保性。The tantalum cover 200 is used to seal the circular opening 120 of the tantalum shell 100 to seal the electrolyte and electrode plates in the accommodating space 110 and ensure the sealing of the tantalum capacitor. Specifically, during the packaging process of the electrolyte and the electrode plate, the tantalum cover 200 is rotated, the tantalum cover 200 is removed from the circular opening 120, and the electrolyte and the electrolytic plate are sequentially installed into the accommodation space 110. Specify the location, and then insert the tantalum cover 200 into the circular opening 120 and gradually tighten the tantalum cover 200 so that the external threads 211 of the tantalum cover 200 and the internal threads 121 of the circular opening 120 are screwed and locked, thereby realizing the tantalum shell 100 sealing work. Please refer to FIG. 3 . In one embodiment, a leak-proof rubber ring 212 is provided on the side of the cover 210 facing away from the accommodating space 110 . The leak-proof rubber ring 212 abuts against the outer edge of the circular opening 120 . By providing an anti-leakage rubber ring 212 on the cover plate 210, the gap between the internal thread 121 and the external thread 211 can be further sealed to prevent the electrolyte from leaking into the environment, thereby causing corrosion of the tantalum capacitor's epitaxial equipment. problems to improve the safety and environmental protection of tantalum capacitors.
拉杆220用于带动盖板210转动，以降低盖板210转动的难度，从而提高钽电容器的组装效率。一实施例中，盖板210与拉杆220一体式成型。通过使盖板210与拉杆220一体式成型，拉杆220不易从盖板210上脱落，提高了盖板210与拉杆220连接的稳定性及拉杆220受力运动向盖板210传动的可靠性，并延长了零配件的使用寿命。一实施例中，拉杆220具有弧形拉持部221。通过在拉杆220上设置弧形拉持部221，增大了人手部与拉杆220的接触面积，减小了拉杆220对人手部的损伤，进而降低了拉杆220及盖板210转动的难度，提升了钽电容器的组装效率。The pull rod 220 is used to drive the cover plate 210 to rotate, so as to reduce the difficulty of rotating the cover plate 210, thereby improving the assembly efficiency of the tantalum capacitor. In one embodiment, the cover plate 210 and the tie rod 220 are integrally formed. By making the cover plate 210 and the tie rod 220 integrally formed, the tie rod 220 is not easy to fall off from the cover plate 210, which improves the stability of the connection between the cover plate 210 and the tie rod 220 and the reliability of the force transmission of the tie rod 220 to the cover plate 210, and Extended service life of spare parts. In one embodiment, the pull rod 220 has an arc-shaped holding portion 221 .
