Abstract
The utility model relates to a plastic packaging vacuum relay comprising a vacuum relay seat body (1) and a ceramic vacuum sealing cover (2). Pins (3) of a relay switch contact are led out from the ceramic vacuum sealing cover (2), and insulation silica gel (4) is encapsulated between the vacuum relay seat body (1) and the ceramic vacuum sealing cover (2), so that voltage resistance is improved by multiple times under the condition that the amplitude of increase of the volume of the traditional vacuum relay is small, and the plastic packaging vacuum relay can be widely applied to the field of vacuum relays.
Description
Technical field
The utility model relates to the relay field, especially a kind of plastic packaging vacuum relay.
Background technology
Ceramic vacuum relay has the ability of handle high power, under harsh conditions such as high pressure, big electric current, still have conventional relay characteristics such as incomparable reliability and long service life, be widely used in the high frequency high-tension apparatuses such as communication, industrial heating, semiconductor machining, imaging of medical, Hi-pot test.It is medium with the vacuum, pottery is a shell, because vacuum is a perfect medium, withstand voltage (the withstand voltage 1kv/mm of being approximately between the contact that air breaks that often do not have problems, withstand voltage in the vacuum is airborne more than 10 times), the high pressure exit pin of relay is fixing by pottery, so product maximum withstand voltage is subjected to the distance restriction between contact that ceramic surface disconnects, in theory for improving the product withstand voltage properties, should improve the distance between external contact, but we can not be unlimited increases small product size as far as possible.When 30kV was above, because volume is excessive, cost was too high, does not almost have practical value as existing vacuum relay.
The utility model content
The technical problems to be solved in the utility model provides the plastic packaging vacuum relay that a kind of inner vacuum medium and outside plastic packaging medium and insulation crust, high-voltage connection combine.
The technical solution of the utility model is: a kind of plastic packaging vacuum relay, comprise vacuum relay pedestal, ceramic vacuum seal closure, the pin of relay switch contacts is drawn by the ceramic vacuum seal closure, it is characterized by: embedding has insulation silica gel between vacuum relay pedestal and ceramic vacuum seal closure.
Described pin is a high-voltage line.
The dielectric strength of described insulation silica gel reaches 10
12More than the volt.
The utility model adopts insulation silica gel that vacuum relay is encapsulated in the insulation crust, contact point is drawn with high-voltage line, utilize the combination of inner vacuum medium and outside plastic packaging medium and insulation crust, high-voltage connection, effectively solved the problem of withstand voltage of vacuum relay product surface, make the raising of product withstand voltage one-tenth multiple under the situation that finite volume increases, for the miniaturization of high-power relay provides brand-new thinking.
Description of drawings
Fig. 1 is the utility model plastic packaging vacuum relay structural representation.
Embodiment
Embodiment 1:
A kind of plastic packaging vacuum relay, as shown in Figure 1, at first clean vacuum relay pedestal 1, ceramic vacuum seal closure 2 parts such as grade, high-voltage line flexible cord 3 with relay switch contacts, draw from ceramic vacuum seal closure 2, during then with insulation silica gel 4 surface coverage, silica gel 4 is filled between vacuum relay pedestal 1 and the ceramic vacuum seal closure 2, and note the position, corner is smoothened, prevent that silica gel 4 from can not cover whole surface fully, then goods being placed to leave standstill in the dust-free workshop or in the dustless case allows silica gel 4 natural exhausts steep 1 hour, trickling evenly, ambient temperature is not higher than 30 degree, expands when preventing that silica gel 4 is heated and produces bubble; After treating that standing and defoaming is finished, it is 80 ℃ baking oven that goods are put into temperature, and the baking 10 minutes down of air blast state can the full solidification sealing, obtains this plastic packaging vacuum relay.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
Claims (1)
1. plastic packaging vacuum relay, comprise vacuum relay pedestal (1), ceramic vacuum seal closure (2), the pin of relay switch contacts (3) is drawn by ceramic vacuum seal closure (2), it is characterized by: embedding has insulation silica gel (4) between vacuum relay pedestal (1) and ceramic vacuum seal closure (2).
