The vacuum relay mainly comprises a vacuum pipe, a coil, an input electrode and an output electrode, and is characterized in that the input electrode and the output electrode are fixedly arranged in the vacuum pipe through reinforced ends; the rear end of the input electrode is pipe-shaped; the front end of the input electrode is bent 30 to 45 degrees downwards along the axis of the input electrode and has a slightly Z shovel shape; the shovel-shaped part extends forwards and is parallel to the axis of the input electrode; a small hole is formed in the downwards bent top corner and communicated with a pipe cavity of the input electrode; and a closed body is arranged at the tail end of the input electrode and formed by hot-melting the residual part material of the input electrode. During processing, the input electrode and the output electrode are assembled, fixedly arranged on a fixture and sleeved with the vacuum pipe with two unclosed ends, the two ends of the vacuum pipe are hot-melted by a spray gun to form the reinforced ends, the input electrode and the output electrode are fixedly arranged in the vacuum pipe, air in the vacuum pipe is extracted through a pipe orifice and the small hole of the input electrode, the pipe orifice at the tail end of the input electrode is quickly hot-melted to form the closed body, and the coil is sleeved outside the vacuum pipe.

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 by control system (but also claiming output loop), usually be applied in the automatic control circuit, in fact use less electric current to remove to control a kind of " automatic switch " of larger electric current.In circuit, play the effects such as automatic adjusting, safeguard protection, change-over circuit, use very extensive.Particularly a kind of vacuum relay is not only high pressure resistant, and highly sensitive, is aerospace field relay commonly used.But because vaccum case is the nature of glass, the operation that vacuumizes in the course of processing brings a lot of troubles for the manufacturing of this product, particularly after installing intraware, row vacuumizes again, usually stay suction nozzle at body, the projection as the glass liner of thermos bottom affects 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 the upper position near armature (13) of vacuum tube (1), the input utmost point (3) rear end is tubulose, the flat shovel shape that slightly is " Z " font behind 30 °～45 ° of the downward deviations of axial line of the front end edge input utmost point, shovel shape section 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, static contact spring piece (8) is put in the shovel shape section 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 cylinder, 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 make the front end face of plates (10) and the shovel section that inputs the utmost point (3) remain on same level 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, its rear end is between shovel section and plates (10) at output stage (4) put in rivet (16) riveting, the front center bottom surface is installed with armature (13), the above is installed with stop (14), stop (14) is the cylinder with base, be inverted "T"-shaped during side-looking, the corresponding position of the fixed contact (9) that is installed with in 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) by adding fixed end (5) and (6) respectively, the top of stop (14) is under the elastic force effect of movable contact spring (11), 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 makes, and static contact spring piece (8) movable contact spring (11) is copper material; Add to input first man-hour and be installed with on anchor clamps after the utmost point (3) and output stage (4) and assembly thereof machine, and put the not yet airtight vacuum tubes in two ends (1), 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), then extract the interior air of vacuum tube out by the mouth of pipe and the aperture (7) of the input utmost point (3), and the terminal mouth of pipe of the hot melt input utmost point (3) forms obturator (17) rapidly, then is nested with coil (2) and gets final product outside vacuum tube (1).

This technique vacuumizes by the input utmost point owing to being after the intraware assembling is complete again, therefore can not stay the pumping mouth vestige at canals of stilling, and traditional machining tool need not improved or change, and has simplified technological process, has improved production efficiency.
