Abstract
A silicon rubber ring for a capacitor cover plate relates to the technical field of capacitors, comprises a cylindrical rubber body and is characterized in that a rivet hole is arranged in the middle of the rubber body, an upper boss is arranged at the upper end of the rubber body, a lower boss is arranged at the lower end of the rubber body, the diameter of the upper boss is smaller than that of the rubber body, and the diameter of the lower boss is smaller than that of the upper boss. The silicon rubber ring has a simple structure, is reasonable in design, the bosses are arranged at the upper end and the lower end of the cylindrical rubber body, and the diameters of the bosses are both smaller than the diameter of the rubber body, so that the rubber body has space for generating deformation after being extruded, the rubber body and an extrusion piece are contacted closely, and a sealing effect is good.
Description
Technical field:
The utility model relates to the capacitor technology field, relates in particular to a kind of capacitor cover plate silicon rubber loop.
Background technology:
Electric capacity is called in the common letter of capacitor, is a kind of device that holds electric charge.Electric capacity is one of a large amount of electronic components that use in the electronic equipment, is widely used in separated straight-through friendship the in the circuit, coupling, bypass, filtering, resonant tank, power conversion, aspects such as control.
In the prior art, capacitor cover plate all is made up of inserted sheet, insulating base, cover plate body, sealing ring, connection cardboard and rivet, connects cardboard, sealing ring, cover plate body and insulating base and is connected in series the location successively each other through rivet.Mostly the sealing ring that uses at present is silicon rubber loop, and silicon after the assembly at two ends compresses up and down deformation takes place as cushion rubber, finally is squeezed into washer-shaped.But the traditional silicon seal with elastometic washer effect of using is not very desirable, and structure needs further to optimize to improve.
The utility model content:
The utility model technical problem to be solved is to overcome the defective of prior art, and a kind of capacitor cover plate silicon rubber loop of good sealing effect is provided.
The utility model technical problem to be solved adopts following technical scheme to realize:
The capacitor cover plate silicon rubber loop comprises columniform rubber bodies, it is characterized in that: have rivet hole in the middle of the said rubber bodies, the rubber bodies upper end is shaped on convex platform, and the rubber bodies lower end is shaped on lower convex platform.
The diameter of said convex platform is less than the rubber bodies diameter.
The diameter of said lower convex platform is less than the convex platform diameter.
The utility model is simple in structure, and is reasonable in design, and columniform rubber bodies is provided with boss in two ends up and down; And the boss diameter is all less than the rubber bodies diameter; Thereby make rubber bodies that the space that deformation takes place arranged after being squeezed, rubber bodies is tightr with contacting of extrusion, good sealing effect.
Description of drawings:
Fig. 1 is the main half sectional view of the utility model;
Fig. 2 is the vertical view of the utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Like Fig. 1, shown in Figure 2; The capacitor cover plate silicon rubber loop comprises columniform rubber bodies 2, has rivet hole 4 in the middle of the rubber bodies 2; Rubber bodies 2 upper ends are shaped on convex platform 1; Rubber bodies 2 lower ends are shaped on lower convex platform 3, and the diameter of convex platform 1 is less than rubber bodies 2 diameters, and the diameter of said lower convex platform 3 is less than convex platform 1 diameter.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
