Description

Technical Field

[0001] The utility model relates to the technical field of relay ceramic covers, in particular to a metallized ceramic cover for a high-voltage relay. Background Technique

[0002] A high-voltage relay is an electrical appliance that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change of the input quantity (excitation quantity) of the high-voltage circuit reaches the specified requirement. A high-voltage relay is an electronic control device that has a control system (also known as the input circuit) and a controlled system (also known as the output circuit), and is usually applied to an automatic control circuit;

[0003] The existing high-voltage relays are generally protected by ceramic covers to prevent dust from accumulating inside the high-voltage relays. However, the current ceramic covers are generally installed and fixed by screws. When the high-voltage relays are overhauled, the ceramic covers are difficult to disassemble, which affects the overhaul efficiency. Therefore, a metallized ceramic cover for a high-voltage relay is proposed. Summary of the Utility Model

[0004] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Simplifications or omissions may be made in this part as well as in the abstract and the title of the description of this application to avoid obscuring the purpose of this part, the abstract of the description, and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the utility model.

[0005] Therefore, the purpose of the utility model is to provide a metallized ceramic cover for a high-voltage relay. By rotating the adjusting bolt, the adjusting bolt rotates in the connecting hole and is screwed with the threaded groove, driving the connecting seat to slide in the connecting groove, thereby separating or assembling the ceramic cover housing and the base. While facilitating the disassembly and assembly of the ceramic cover housing, the integral ceramic cover structure is changed to a split structure, which is convenient for subsequent replacement, overhaul and other operations. When a certain structure is damaged, there is no need to replace the whole, saving resources.

[0006] To solve the above technical problems, according to one aspect of the utility model, the following technical solutions are provided by the utility model:

[0007] A metallized ceramic cover for a high-voltage relay, which comprises:

[0008] A base as a connection base, on which a connection groove is opened, two groups of sliding grooves are symmetrically opened in the connection groove, a connection hole is opened in the base, an adjusting bolt is rotatably connected in the connection hole, and a connection plate connected to the relay is arranged on the top of the base;

[0009] The ceramic cover component is connected to the base and includes a connecting seat connected to the connecting groove. The bottom of the connecting seat is integrally formed with a sliding seat that slidably cooperates with the sliding groove. A threaded groove that is screwed and cooperated with the adjusting bolt is provided on the outer side of the connecting seat, and a ceramic cover housing is arranged on the top of the connecting seat.

[0010] As a preferred solution of the metallized ceramic cover for a high-voltage relay described in the present utility model, wherein: the connecting groove is arranged in a concave shape, and the connecting seat is arranged in a convex shape.

[0011] As a preferred solution of the metallized ceramic cover for a high-voltage relay described in the present utility model, wherein: through holes are provided on the outer side of the ceramic cover housing, and a ventilation component is connected at the positions corresponding to the through holes.
