Abstract

The invention discloses a processing technique for a vacuum relay. In processing technique, a vacuum tube, a coil and assemblies of an input pole and an output pole are mainly applied. The processing technique for the vacuum relay is characterized in that the input pole and the output pole are respectively and fixedly arranged in the vacuum tube through reinforcing ends; the rear end of the input pole is tubular; the front end of the input pole is downwards deflected by 30-45DEG C along the axial lead of the output pole and then is slightly in Z-shaped shovel shape; the shovel-shaped part forwards extends and is in parallel to the axial lead of the input pole; a small hole is arranged at the downwards-bent vertex angle and is communicated with a tubular cavity of the input pole; and an airtight body is arranged at the tail end of the input pole and is formed by hot melting of residual part of material of the input pole. The processing technique comprises the following steps of: firstly, assembling the input pole and the output pole and then fixing the assembled body on a clamp; sleeving the vacuum tube of which two ends are not closed on the clamp; forming the reinforcing ends at two ends of the hot smelting vacuum tube of a spray gun and enabling the input pole and the output pole to be fixedly arranged in the vacuum tube; secondly, extracting air in the vacuum tube through a tube mouth of the input pole and the small hole and quickly carrying out hot smelting on the tube mouth at the tail end of the input pole to form the airtight body; and finally, sleeving a coil outside the vacuum tube.

Description

The processing technology of vacuum relay

Technical field

The present invention relates to a kind of processing technology of relay.

Background technology

Relay is a kind of electronic control device; It has control system (claim not only input circuit) and Be Controlled system (but also claiming output loop); Usually be applied in the automatic control circuit, in fact use less current to remove to control a kind of " automatic switch " of bigger electric current.In circuit, play effects such as automatic adjusting, safeguard protection, change-over circuit, use very extensive.Particularly a kind of vacuum relay, not only high pressure resistant, and also highly sensitive, be aerospace field relay commonly used.But because vaccum case is the nature of glass, the operation that in the course of processing, vacuumizes brings a lot of troubles for the manufacturing of this product, particularly after installing intraware; Row vacuumizes again; Usually on body, stay suction nozzle, the convexity as the glass liner of thermos bottom influences product appearance.

Summary of the invention

The processing technology of vacuum relay is exactly for addressing the above problem disclosed a kind of technical scheme.Mainly comprise: vacuum tube (1), coil (2), the input utmost point (3), output stage (4), movable contact spring (11), armature (13), fixed contact (9), moving contact (15); It is characterized in that: vacuum tube (1) is for glass tubular, and two ends are for adding fixed end (5), (6), vacuum tube (1) and add fixed end (5), (6) are one-body molded; Coil (2) is nested with at vacuum tube (1) and goes up the position near armature (13), and the input utmost point (3) rear end is a tubulose, slightly is the flat shovel shape of " Z " font behind 30 °～45 ° of the downward deviations of axial line of the front end edge input utmost point; Shovel shape portion protract and with the axis parallel of the input utmost point; At its drift angle place that bends downwards, be equipped with aperture (7), aperture (7) communicates with the tube chamber of the input utmost point (3); The end of the input utmost point (3) is equipped with obturator (17); Obturator (17) is that the remainder material hot melt of the input utmost point (3) forms, and static contact spring piece (8) is put in the shovel shape portion riveting of the input utmost point (3), is installed with fixed contact (9) on the static contact spring piece (8); Output stage (4) is identical with the shape of the input utmost point (3); The part that places the outer end that adds fixed end (6) is a cylinder, and the cross section roughly was the plates (10) of serpentine when the front end shovel faced down and a side-looking is put in riveting under the shovel face, and makes the front end face of plates (10) and the shovel portion that imports the utmost point (3) remain on same horizontal plane and keep 3～4mm distance; The front end of plates (10) is nested with insulating barrier (12) near the position of armature (13); The cross section also slightly is serpentine during movable contact spring (11) side-looking, and put between the shovel portion and plates (10) at output stage (4) through rivet (16) riveting its rear end, and the front center bottom surface is installed with armature (13); Be installed with stop (14) above; Stop (14) is inverted " T " shape for having the cylinder of base during side-looking, the corresponding position of fixed contact (9) that is installed with on the movable contact spring front end and the input utmost point (3) is installed with moving contact (15); The input utmost point (3) output stage (4) is installed with in vacuum tube (1) through adding fixed end (5) and (6) respectively; The top of stop (14) is under the elastic force effect of movable contact spring (11), and overhead and is in moving contact (15) and fixed contact (9) often to open shape on the inwall of vacuum tube (1); The input utmost point (3) output stage (4) utmost point armature is soft magnetic material and processes, and static contact spring piece (8) movable contact spring (11) is copper material; Add to import earlier man-hour and be installed with on anchor clamps after the utmost point (3) and output stage (4) and assembly thereof machine; And put two ends enclosed vacuum pipe (1) not as yet; The two ends of spray gun hot melt vacuum tube (1) form and add fixed end (5) and (6); And the input utmost point (3) output stage (4) is installed with in vacuum tube (1); Extract the air in the vacuum tube out through the mouth of pipe and the aperture (7) of the input utmost point (3) then, and the terminal mouth of pipe of the hot melt input utmost point (3) forms obturator (17) rapidly, outside vacuum tube (1), is nested with coil (2) then and gets final product.

This technology vacuumizes through the input utmost point owing to be after the intraware assembled again, therefore can on canals of stilling, not stay the pumping mouth vestige, and the traditional processing instrument need not improved or change, and has simplified technological process, has improved production efficiency.
