Locomotive capacitor for protecting casing and column head

Abstract

The invention discloses a locomotive capacitor for protecting a housing and terminal heads. The locomotive capacitor comprises the housing and a cover plate, wherein the housing and the cover plate enclose to form a box body, and a core is installed in the box body; two first circular holes are formed in the cover plate, and wiring terminal grooves are formed in the upper ends of the first circular holes. The locomotive capacitor avoids the traditional welding fixed wiring terminals, adopts the wiring terminal grooves for mounting the wiring terminals, each wiring terminal is a metal cylinderand penetrates the corresponding wiring terminal groove vertically, and upper and lower side surfaces of a tray abut against balls in second cylindrical holes and are in rolling fit with the balls, thereby ensuring that unstable connection between lead wires and the wiring terminals caused by random movement of the lead wires when the terminal heads are connected with the lead wires cannot occur.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a motorcycle capacitor for protecting a casing and a column head. Background technique [0002] Capacitors are essential components in the terminals of various electronic products and play a vital role in electronic systems. In applications such as industry and power supply, system manufacturers have more urgent needs for capacitors with high capacity, low ESR, and small size. higher requirements. [0003] The terminal of the capacitor is generally installed on the cover plate, and they are all fixedly installed, and then used to passively connect the wires. The connection of the wires is also fixedly connected. Torque is generated between the terminals. Under normal circumstances, tin foil is used to weld the terminal and the terminal. Under the action of large torque, it is very easy to damage the connection between the terminal and the wire, and the material of the wire i...

AI Technical Summary

Problems solved by technology

[0003] The terminal of the capacitor is generally installed on the cover plate, and they are all fixedly installed, and then used to passively connect the wires, and the connection of the wires is also fixedly connected. Torque is generated between the terminal heads. Generally, tin foil is used to weld the wire head and the terminal. Under the action of large torque, it is very easy to damage the connection between the terminal and the wire, and the material of the wire is usually a single round copper wire. , it is particularly stiff, even if multiple thin copper wires are used, the torsion force will be generated accordingly

[0004] The main problem to be solved by the present invention is that the casing of the capacitor often bulges and the terminal connection is unstable during long-term use
