Description

Quick-connect capacitor cover mechanism

technical field

The utility model belongs to the technical field of electronic components, relates to a capacitor, in particular to a quick-connect capacitor cover plate mechanism.

Background technique

Capacitors, usually referred to as capacitance for their ability to hold charges, are denoted by the letter C. As the name suggests, it is a "charged container", a device that holds charges. Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control, etc. in circuits.

In the process of charging and discharging, the charge on the two plates of the capacitor accumulates, that is, the voltage builds up. Therefore, the voltage on the capacitor cannot change suddenly. Once the change occurs, the capacitor will burn out and need to be repaired. The existing capacitors and circuits usually need to be connected by wires, and the connection process requires welding. In some cases where there are no welding conditions (such as power failure), it is easy to cause difficulties in emergency repairs, and the connection between capacitors and wires cannot be quickly realized.

The research of the prior art often focuses on how to improve the working temperature and safety of the capacitor. For example, the Chinese patent document discloses a capacitor [authorized announcement number: CN101258570B], which includes a dielectric layer formed on the entire surface of the porous anode body. An electrical layer and a conductive cathode formed on said dielectric layer, the anode body and the cathode layer are preferably connected to the anode and cathode terminals of the capacitor, respectively.

As shown in FIG. 1 , a quick-connect capacitor cover mechanism includes a cover assembly 10. Two electrodes 20 are fixed on the cover assembly 10, and the two electrodes 20 can be respectively connected to the positive pole and the negative pole of the capacitor. The electrode 20 is covered with a conductive connecting post 30 fixedly connected to the electrode 20. The cross-sectional shape of the connecting post set on the two electrodes 20 is different, which is convenient for intuitively and quickly distinguishing the positive and negative poles, thereby improving the wiring efficiency. speed and also prevents wiring errors. The connecting post 30 has a connecting hole 31 for the insertion of wires, and the end of the connecting hole 31 close to the electrode 20 has an annular clamping ring 32 protruding toward the axis of the connecting hole 31, and the wires pass through the connecting hole. 31 is inserted into the inside of the connecting column 30. When it is close to the clamping ring 32, the end of the wire is directly clamped by the clamping ring 32 to form a conduction, thereby realizing the quick connection between the wire and the capacitor. The performance is particularly fast. In order to facilitate the insertion of wires into the clamping ring 32 , in this embodiment, the surface of the clamping ring 32 is specifically designed, that is, the clamping ring 32 has a smooth arc-shaped surface.

Regarding the cross-sectional shape of the connecting post 30 , it can be triangular, polygonal, circular, etc., but the cross-sectional shapes of the connecting post 30 on the two electrodes 20 must be different. As shown in Figure 2, the sections of the two connecting columns 30 are square and circular respectively, as shown in Figure 3, the sections of the two connecting columns 30 are respectively square and triangular, as shown in Figure 4, the two connecting columns 30 The cross-sections are square and borderless, respectively.

The outer wall of the connecting column 30 and the position corresponding to the clamp ring 32 are inwardly recessed to form an annular pincer ring 33, and the clamp ring 33 can be clamped in the pincer ring 33 with special-purpose clamping pliers, so that the pincer ring 32 in the clamp ring 32 can be clamped. The wire is fixed to prevent the wire from detaching from the connecting post 30 .

Preferably, the cover plate assembly 10 includes a support plate 11 , and an insulating layer 12 is provided on both sides of the support plate 11 . The insulating layer 12 can be coated with a resin material, or an existing insulating plate or rubber plate can be used.
