Technical field

The present invention relates to relay technical fields, more particularly to a kind of closed type high voltage direct current relay.

Background technique

Summary of the invention

It is an object of the invention to overcome the deficiency of the prior art, provides a kind of closed type high voltage direct current relay, passes through Improvement to exhaust pipe structure had both been avoided due to causing between two load exits exhaust pipe in ceramic shield The drawbacks of insulation performance is deteriorated also avoids the winding space since exhaust pipe to be made to magnetic circuit part in magnetic circuit part The drawbacks of becoming smaller.

The technical solution adopted by the present invention to solve the technical problems is: a kind of closed type high voltage direct current relay, including Ceramic shield, two loads exit, metal frame piece, yoke plate and copper exhaust pipes；Wherein, ceramic shield is substantially rectangular, yoke Iron plate is generally circular；Described two load exits are attached separately at the roof of ceramic shield, the bottom end of two load exits It is put in the cavity of ceramic shield respectively；The peripheral size pair of the bottom end of the peripheral size and ceramic shield on the top of the metal frame piece It should be adapted, and the bottom end of ceramic shield is fixed on the top of metal frame piece；The bottom end of the metal frame piece is on the periphery of yoke plate It is mutually fixed with yoke plate in range, so that the metal frame piece is surrounded one from top to bottom end and be connected with the cavity of ceramic shield Frame piece cavity；The frame piece cavity also integrally extends the side chamber body not covered by the ceramic shield, the row to side Tracheae is at the roof of the side chamber body of the metal frame piece, and the bottom end of the exhaust pipe is protruded into the side chamber body, to make The exhaust pipe is in a side for outside the ceramic shield and being in ceramic shield.

It is mutually fixed between the exhaust pipe and the roof of the side chamber body of the metal frame piece by soldering.

The roof of the side chamber body of the metal frame piece is equipped with through-hole, and the bottom end of the exhaust pipe is equipped with step surface directed downwardly Rank, the bottom end of the exhaust pipe are inserted in the through-hole of metal frame piece, and the step of exhaust pipe is against the upper edge of the through-hole of metal frame piece Place.

Height of the height of the side chamber body of the metal frame piece lower than the frame piece cavity of the metal frame piece.

Frame piece cavity of the side chamber body of the metal frame piece in the central region for the line for corresponding to two load exits In a side thereto deflect away from.

The top of the metal frame piece is equipped with the first flanging that direction is bent into frame, and the metal frame piece passes through the first folding Side and the bottom end of ceramic shield are mutually fixed；The bottom end of the metal frame piece is equipped with the second flanging bent to outer frame direction, the gold Belong to frame piece mutually to fix by the second flanging with yoke plate；Second flanging be paperwrapped in the metal frame piece frame piece cavity and The side chamber body of metal frame piece.

Compared with prior art, the beneficial effects of the present invention are:

The present invention also integrally extends the side not covered by the ceramic shield by using frame piece cavity to side Cavity, for the exhaust pipe at the roof of the side chamber body of the metal frame piece, the side chamber is protruded into the bottom end of the exhaust pipe In body, so that the exhaust pipe be made to be in a side for outside the ceramic shield and being in ceramic shield.This structure of the invention is When being matched using substantially rectangular ceramic shield and generally circular yoke plate, had on the yoke plate of ceramic shield side Side chamber body is arranged in some spatial positions, and exhaust pipe is installed at side chamber body, will not change the volume of original relay, continues Keep the small size feature of original relay；Since exhaust pipe is not mounted in ceramic shield, the prior art is avoided because of exhaust pipe The drawbacks of causing the insulation performance between two load exits to be deteriorated in ceramic shield, since exhaust pipe is installed in metal Frame on piece, the top in yoke plate avoid the prior art because exhaust pipe is in magnetic circuit part and make magnetic circuit part The drawbacks of winding space becomes smaller；This structure of the invention, can both guarantee between two load exits have meet the requirements Insulating space, and make magnetic circuit part winding space maximize, improve the magnetic circuit performance of product.

Invention is further described in detail with reference to the accompanying drawings and embodiments；But a kind of closed type high pressure of the invention DC relay is not limited to the embodiment.
