Abstract

The utility model relates to a feed-through capacitor used for magnetrons, which comprises an upper plug (1), a socket (2), a box cover (3) and a lower plug (4), wherein the lower plug (4) is arranged at the lower end of the box cover (3), the socket (2) is arranged at the upper end of the box cover (3), and the upper plug (1) is arranged at the top of the socket (2); the top of the socket (2) is provided with an outward convex station (21). Because the feed-through capacitor adopts the structure that the outward convex station is arranged on the top of the socket, not only the creepage distance satisfies the request for utilization, but also the integral structure is greatly reduced, so that the structure of the magnetron is more compact. The feed-through capacitor of the utility model has rational design and simple structure, and can satisfy the request for utilization.

Description

A kind of novel feedthrough capacitor

1, technical field:

The utility model is a kind of feedthrough capacitor that is used for magnetron, belongs to the renovation technique of the used electric capacity of magnetron.

2, background technology:

Existing magnetron with the structure of feedthrough capacitor shown in Fig. 3,4, in order to reach the requirement of creepage distance, need its base designs is very big so that occupation space is bigger when being assembled in magnetron.

3, summary of the invention:

The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of creepage distance that not only guarantees to satisfy instructions for use, and dwindles integrally-built magnetron greatly.

Structural representation of the present utility model as shown in Figure 1, include plug (1), base (2), lid (3), following plug (4), wherein play plug (4) to be installed in the lower end of lid (3), base (2) is installed in the upper end of lid (3), last plug (1) is installed in the top of base (2), and wherein outer lug boss (21) has been made at the top of base (2).

The utility model is owing to adopt the structure of making outer lug boss in base top, so it guarantees that not only creepage distance satisfies instructions for use, and dwindles overall structure greatly, makes the more compact structure of magnetron.The utility model is a kind of reasonable in design, simple in structure, can satisfy a kind of novel feedthrough capacitor of instructions for use.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of base in the utility model (2);

Fig. 3 is the prior art constructions schematic diagram;

Fig. 4 is the structural representation of base in the prior art (2);

5, embodiment:

Embodiment:

Structural representation of the present utility model as shown in Figure 1, 2, include plug (1), base (2), lid (3), following plug (4), wherein play plug (4) to be installed in the lower end of lid (3), base (2) is installed in the upper end of lid (3), last plug (1) is installed in the top of base (2), and wherein outer lug boss (21) has been made at the top of base (2).The utility model can guarantee that creepage distance more than or equal to 15.5mm, has dwindled the overall structure of feedthrough capacitor greatly, makes the more compact structure of magnetron, and has reached desired specification requirement.

Claims (1)

1, a kind of novel feedthrough capacitor, include plug (1), base (2), lid (3), following plug (4), wherein play plug (4) to be installed in the lower end of lid (3), base (2) is installed in the upper end of lid (3), last plug (1) is installed in the top of base (2), it is characterized in that outer lug boss (21) has been made at the top of base (2).
