The utility model discloses an improved structure for an electrode disc of a vacuum capacitor. A plurality of fixing ring grooves sharing the same center shaft with the electrode disc are formed on the mounting surface of the electrode disc; a plurality of electrode rings are correspondingly fixed in the fixing ring grooves; a plurality of fan-shaped convex surfaces are uniformly distributed on the mounting surface of the electrode disc along the center of the mounting surface; and fan-shaped concave surfaces corresponding to the fan-shaped convex surfaces are arranged at the back of the electrode disc. The fan-shaped convex surfaces and the fan-shaped concave surfaces are identical in shape, and by adopting the concave-convex improved structure, the mechanical strength and the dimensional stability of parts are improved. The fixing ring grooves are formed on the fan-shaped convex surfaces. Under the premise that the mounting size of the capacitor does not change, the electrode disc structure is improved, the manufacturing cost of the vacuum capacitor is lowered, and the airtightness, the mechanical strength and the dimensional stability of the product are effectively improved.

Background technology
The electrode disk shaping structures complexity of universal vacuum capacitor adopts round bar through the Vehicle Processing moulding, and required raw material are many, and the part processing operation is many, the production cost height of part; Simultaneously exist air-tightness and mechanical strength low owing to draw the bar of moulding, the qualification rate that part is produced is low, also causes the decline of product quality and the increase of production cost.Along with vacuum capacitor product promoting the use in the high-frequency heating apparatus field, price and manufacturing cost to product have proposed new requirement, requirement to products air tightness and mechanical strength also further improves, and the electrode disk of existing structure is difficult to processing and reaches requirement under limited processing cost.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of structure-improved of electrode disk of vacuum capacitor, and shaping structures is simple, and effectively reduces production costs and improve air-tightness, mechanical strength and the dimensional stability of product.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of structure-improved of electrode disk of vacuum capacitor, offer plurality of fixed annular groove some and the concentricity axle of this electrode disk on the installed surface of described electrode disk, some electrode retaining collar correspondences are fixedly welded in the described plurality of fixed annular groove, be evenly distributed with some fan-shaped convex surfaces on the installed surface of described electrode disk around its center, the electrode disk reverse side of this fan-shaped convex surface corresponds to fan-shaped concave surface, the shape of fan-shaped convex surface and fan-shaped concave surface is identical, adopted the concaveconvex structure improvement, improve the mechanical strength and the dimensional stability of part, described fixedly annular groove is opened on the described fan-shaped convex surface.
As further improvement of the utility model, the quantity of described fan-shaped convex surface is even number, and its distribution is symmetry in twos.
As further improvement of the utility model, the quantity of described fan-shaped convex surface is six
As further improvement of the utility model, the electrode disk of described vacuum capacitor is the plate dish by the moulding of integrated punching stretching beading; Plate substitutes bar, adopts the moulding of punching stretch beading, has improved working (machining) efficiency greatly; And, improved the qualification rate of vacuum capacitor product because the air-tightness of plate, has been eliminated the phenomenon of welding rear electrode dish gas leakage greater than the air-tightness of bar.

Embodiment
Embodiment: a kind of structure-improved of electrode disk of vacuum capacitor, offer plurality of fixed annular groove 10 some and the concentricity axle of this electrode disk on the installed surface of described electrode disk 1, some electrode retaining collar 2 correspondences are fixedly welded in the described plurality of fixed annular groove, be evenly distributed with some fan-shaped convex surfaces 11 on the installed surface of described electrode disk 1 around its center, the electrode disk reverse side of this fan-shaped convex surface 11 corresponds to fan-shaped concave surface 12, fan-shaped convex surface 11 is identical with the shape of fan-shaped concave surface 12, adopted the concaveconvex structure improvement, improve the mechanical strength and the dimensional stability of part, described fixedly annular groove 10 is opened on the described fan-shaped convex surface 11.
The quantity of described fan-shaped convex surface 11 is even number, and its distribution is symmetry in twos.
The quantity of described fan-shaped convex surface 11 is six
The electrode disk of described vacuum capacitor is the plate dish by the moulding of integrated punching stretching beading; Plate substitutes bar, adopts the moulding of punching stretch beading, has improved working (machining) efficiency greatly; And, improved the qualification rate of vacuum capacitor product because the air-tightness of plate, has been eliminated the phenomenon of welding rear electrode dish gas leakage greater than the air-tightness of bar.
Fig. 1 and Fig. 2 are the schematic diagrames of electrode disk of the present utility model, the diameter of electrode disk is that the overall dimension according to product requires to design, electrode disk inner each fixedly the diameter and the degree of depth of annular groove also be to determine according to the technical parameter of product, different product requirements is different.As shown in Figure 3, electrode disk is the strutting piece of each electrode retaining collar in the vacuum capacitor product, therefore requires electrode disk part after operations such as process high-temperature soldering not have gas leak phenomenon and each dimensionally stable no change, thus the capacity of assurance product and withstand voltage.Do not have distortion for each size of assurance electrode disk in welding process, the utility model is designed to symmetrical concaveconvex structure with electrode disk, improves the mechanical strength and the dimensional stability of part.Simultaneously, raw material change to plate by bar, adopt the moulding of punching stretch beading, have improved part processing efficient greatly.Because the air-tightness of plate is much higher than the air-tightness of bar, eliminated the phenomenon of welding rear electrode dish gas leakage, improved the qualification rate of product.
