Description

Technical Field

[0001] The utility model relates to the technical field of capacitors, in particular to a plug-in type capacitor. Background Art

[0002] Capacitors are commonly found in various electronic products, equipment and other application industries. Capacitors include a shell and a capacitor core, which are filled with potting material. A sealing cover is generally provided on the shell, and lead electrodes are installed on the sealing cover. The capacitor core is connected to the lead electrode through a lead copper sheet. During the entire processing process, there are many welding steps and the molding operation is complicated, resulting in high production costs. Summary of the invention

[0003] In order to solve the problems of complex internal structure, complex molding operation and high production cost of existing capacitors, the utility model provides a plug-in capacitor, which has a simple structure, can simplify the molding operation and reduce the production cost.

[0004] The technical solution is as follows: a plug-in capacitor, comprising a shell, a capacitor core is arranged in the shell, and the gap between the capacitor core and the shell is filled with a potting material, characterized in that both sides of the capacitor core are electrode lead-out terminals and a lead-out plug is welded to each of them, and the ends of the lead-out plug are exposed from the potting material and serve as two lead-out electrodes of the capacitor.

[0005] It is further characterized in that the lead-out plug is formed by bending an L-shaped plug, including a vertical plug segment welded to the capacitor core and a bent plug segment exposed to the potting material, and one end of the bent plug segment connected to the vertical plug segment is a bevel;

[0006] The other end of the bent insert segment is bent upward.

[0007] After the utility model is adopted, the lead-out plug-in piece is directly used as the motor, and is directly welded with the capacitor core without an upper cover, and is directly sealed with a potting material, so the structure is simple, the assembly operation is simplified, and the cost is reduced.

[0010] Figure 3 This is another structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] See Figure 1 and Figure 2As shown, a plug-in capacitor includes a shell 1, a capacitor core 2 is arranged in the shell 1, a potting material 3 is filled in the gap between the capacitor core 2 and the shell 1, both sides of the capacitor core 2 are electrode lead-out terminals and a lead-out plug 4 is welded respectively, and the ends of the lead-out plug 4 are exposed from the potting material 3 and serve as two lead-out electrodes of the capacitor.

[0012] The lead-out plug 4 is formed by bending an L-shaped plug, including a vertical plug segment welded to the capacitor core and a bent plug segment exposed to the potting material. The end of the bent plug segment connected to the vertical plug segment is a bevel, which can increase the creepage distance of the lead-out electrode. Directly welding to the capacitor core 2 can reduce the stray inductance of the capacitor. The other end of the bent plug segment can be further bent upwards, such as Figure 3 shown.

[0013] The final pitch of the two lead-out plugs 4 can be adjusted to meet different usage requirements.
