Abstract
The invention discloses a square sealed radio-frequency electromagnetic relay, which comprises a base (1) and a housing (9). A normally open contact (2), a normally closed contact (3), a reed (4) and a reset reed (5) are arranged on the base (1) by means of spot welding. A coil (6), an iron core portion (7) and a yoke (8) are mounted in the housing (9), and the iron core portion (7) is mounted in the coil (6) which is mounted in the yoke (8). The housing (9) is connected with the base (1) by means of fusion welding. The square sealed radio-frequency electromagnetic relay has a function of radio-frequency signal switching, and is high in reliability, universality and matching of radio-frequency characteristic parameters and widely applicable to switching of radio-frequency signals within a frequency range of (0-5) GHz.
Description
Technical field
The present invention relates to a kind of electromechanical compo, particularly a kind of square TO-5 seal radiofrequency electromagnetic relay.
Background technology
Domestic TO-5 hermetically sealed electromagnetic relay mainly contains the circular product of the circular product of one group of transfer contact, two groups of transfer contacts and the square product of two groups of transfer contacts at present, but lacks the square electromagnetic relay that is used to switch radiofrequency signal.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and possesses the square TO-5 seal radiofrequency electromagnetic relay that switches the radiofrequency signal ability, thereby overcomes the deficiency of above-mentioned prior art.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of square TO-5 seal radiofrequency electromagnetic relay.Its formation comprises base and case, and point is welded with make contact, break contact, reed and reset reed on described base; One end points of break contact is welded on the base, and the other end is positioned at the top of make contact; One end points of reed is welded on the base, and the other end is between make contact and break contact; Coil, core portion and yoke are housed in case, and core portion is contained in the coil, and coil is contained in the yoke; Case and base are welded together.
Above-mentioned square TO-5 seal radiofrequency electromagnetic relay, described make contact comprise left side group make contact and right group make contact; Break contact comprises left side group break contact and right group break contact.
Aforesaid square TO-5 seal radiofrequency electromagnetic relay, described reed comprise left side group reed and right group reed.
Beneficial effect of the present invention: operation principle of the present invention: when coil stimulating; Armature is under the effect of electromagnetic attraction; Overcome the counter-force of reset reed, the pusher section glass marble actuating spring on the armature is developed with the yoke pole-face in the back that rotates a certain angle; Two groups of break contacts are broken off, and two groups of make contact are connected.After the coil de-energisation, electromagnetic attraction disappears, under the effect of reset reed recuperability; Reset reed promotes armature and gets back to initial position, and reed returns to initial condition, and two groups of make contact are broken off; Two groups of break contacts are connected, and accomplish the switching of a radiofrequency signal circuit.
Compared with prior art, the present invention has following characteristics: (1) possesses the function that radiofrequency signal is switched.Its radiofrequency characteristics (inserting loss, isolation, voltage standing wave ratio, radio-frequency power transmittability, characteristic impedance) parameter matching is good, and the radiofrequency signal that can be widely used in (0～5) GHz frequency range is switched.(2) good reliability.It is little, in light weight that its reliability index can reach L level failure rate and the volume stipulated among the GJB65B, anti-vibration, impact property index height.(3) versatility is good.Mounting hole site of the present invention and common square TO-5 electromagnetic relay mounting hole site are grid type and install, and versatility is better.

Embodiment
Embodiment 1.Shown in Fig. 1-3, comprise base 1, case 9, point is welded with make contact 2, break contact 3, reed 4 and reset reed 5 on base 1.Make contact 2 wherein includes two groups of contacts of left side group make contact and right group make contact, and break contact 3 includes two groups of contacts of left side group break contact and right group break contact, and reed 4 includes two groups of reeds of left side group reed and right group reed.One end points of break contact 3 is welded on the base 1, and the other end is positioned at the top of make contact 2, and an end points of reed 4 is welded on the base 1, and the other end is between make contact 2 and break contact 3.Coil 6, core portion 7 and yoke 8 are housed in case 9, and core portion 7 is contained in the coil 6, and coil 6 is contained in the yoke 8; Case 9 is welded together with base 1.
During installation, spot welding make contact 2 on base 1 then is welded in 3 of break contacts on the base earlier, 4 of reed parts is welded on the base again, and the reset reed 5 of burn-oning at last forms contact portion; Then coil 6 and core portion 7, yoke 8 are assembled into the magnetic circuit part through the mode of revolving riveting, at last contact portion and magnetic circuit partly being put postwelding becomes the relay part, base 1 is sealed to be welded together with case 9 get final product.
During work; It is as shown in Figure 4 that (10 is the relay boss among the figure; Be used for orientation), after switching on for coil electrode 14 and coil negative pole 18, left side group reed 11 leaves left side group break contact 13 and the right break contact 15 of organizing respectively with the right reed 17 of organizing; Contact with right group make contact 16 with left side group make contact 12 respectively, accomplish once and switch.After cutting off the power supply for coil electrode 14 and coil negative pole 18; Left side group reed 11 leaves left side group make contact 12 and right group make contact 16 respectively with right group reed 17; Contact with right group break contact 15 with left side group break contact 13 respectively, recover two groups of break contact bonding states.
Execution mode of the present invention is not limited to the foregoing description, and the various variations of under the prerequisite that does not break away from aim of the present invention, making all belong within protection scope of the present invention.
