Description

Technical Field

[0001] The invention relates to the technical field of capacitors, in particular to a capacitor with an improved terminal structure. Background Art

[0002] Two conductors close to each other with a non-conductive insulating medium in between constitute a capacitor. When a voltage is applied between the two plates of the capacitor, the capacitor will store charge.

[0003] When installing a capacitor, first insert the conductive head of the capacitor into the solder hole of the circuit board, and then use a soldering iron and solder to fix the conductive head and the pad. Because the larger the capacitance value, the larger the size. Some circuits need to replace capacitors with larger values ​​in the later stage. When the conductive head of the capacitor does not match the position of the pad, the user can choose an adapter that matches the pad and buckle it on the original conductive head of the capacitor, and then install the capacitor with the adapter on the circuit board. The other method is to use a soft wire to solder the conductive head of the capacitor first, and then solder the other end of the soft wire to the pin or the plate on the circuit board. However, when the circuit board shakes with the device, the adapter may move or separate from the adapter when the circuit board shakes, causing unstable connection. When using a soft wire to transfer, it may be unstable to directly wrap it around the conductive head. When using solder, the soldering iron may accidentally touch the protective film on the outer wall of the capacitor, reducing the service life of the capacitor. To this end, we propose a capacitor with an improved terminal structure. Summary of the invention

[0031] When installing a capacitor, first insert the conductive head of the capacitor into the solder hole of the circuit board, and then use a soldering iron and solder to fix the conductive head and the pad. Because the larger the capacitance value, the larger the size. Some circuits need to replace capacitors with larger values ​​in the later stage. When the position of the conductive head of the capacitor does not match the position of the pad, the user can choose an adapter that matches the pad and buckle it on the original conductive head of the capacitor, and then install the capacitor with the adapter on the circuit board. The other method is to use a soft wire to solder it on the conductive head of the capacitor first, and then solder the other end of the soft wire to the pin or the pad on the circuit board. However, when the circuit board shakes with the device, the adapter will , it may move or separate from the adapter when the circuit board shakes, causing unstable connection. When using a soft wire adapter, it may be unstable to directly wrap it around the conductive head. When using solder, the soldering iron may accidentally touch the protective film on the outer wall of the capacitor, reducing the service life of the capacitor. Therefore, the spacing between the conductive heads of the capacitor body 1 can be adjusted by the adjustment mechanism 2, and the connecting column 24 can be used directly. Moreover, different installation methods can be selected through the control mechanism 3, such as insertion welding or soft wire connection. Moreover, the soft wire connection can directly clamp and fix the soft wire without welding, thereby preventing damage to the capacitor.

In this way, the distance between the two connecting columns 24 can be adjusted so that the connecting column 24 can be suitable for the pins or sockets on the circuit board. At the same time, the graphene coating on the inner top wall of the slide plate groove 29 contacts the graphene guide plate 14, so that the conductive stability of the connecting column 24 and the capacitor contact head 12 can be guaranteed.
