Abstract
The invention relates to a minitype sealed radio frequency electromagnetic relay, composed of a contact part, a magnetic circuit part and a relay part. In a contact system, firstly a normally open contact (2) is fixed on a base (1) in a spot welding way, then a normally closed contact (3) is fixed on the base in the spot welding way, and then a spring part is fixed on the base in the spot welding way, and finally a resetting spring (5) is fixed on the base in the spot welding way, thus the contact part is formed; a coil A (6), an iron core part (7) and a yoke iron (8) are assembled into the magnetic circuit part in a screwing and riveting way, the contact part and the magnetic circuit part are subjected to spot welding to form the relay part, and the relay part is sealed with a case (9). The relay in the invention has the advantages of small volume, light weight, vibration resistance, high impact property index and low distributed capacitance, and the contact system is in a special structure, thus the relay in the invention is applicable to a circuit in a special switching mode.
Description
Technical field: the present invention relates to electromechanical compo, particularly a kind of miniature seal radiofrequency electromagnetic relay.
Background technology: the contact system of micro electromagnetic relay mainly contains 1 group of contact conversion (1Z) or two groups of contact conversions (2Z) at present, can not satisfy some special instructions for use, and lacks the micro electromagnetic relay that is used to switch radiofrequency signal.
Summary of the invention: the present invention carries out the uniqueness design to existing contact system structure, and the contact system of new construction has one group of make contact (1H), two groups of break contacts (2D), can satisfy special instructions for use.The mechanical parameter of this miniature seal radiofrequency electromagnetic relay contact system: contact gap, contact sets gap, contact pressure design in contact suitably makes the radiofrequency characteristics parameter matching better, is applicable to that the radiofrequency signal of (0～3) GHz frequency range is switched.
Formation of the present invention: by contact portion, magnetic circuit part and relay are partly formed, elder generation's spot welding make contact on base in contact system, then the break contact point is welded on the base, again reed is partly put and be welded on the base reset reed of burn-oning at last, formation contact portion; Coil and core portion, yoke are assembled into the magnetic circuit part by the mode of revolving riveting, and at last contact portion and magnetic circuit partly being put postwelding becomes the relay part, and with the case sealing by fusing.
After giving the energising of coil electrode exit and negative pole exit, left side reed exit and right reed exit leave left break contact exit and right break contact exit, all contact with make contact, left reed exit and right reed exit are communicated with, form one group of make contact, finish once and switch; After the outage, left reed exit and right reed exit leave make contact, contact with right break contact exit with left break contact exit respectively, recover two groups of break contact states.
Compared with the prior art, the advantage that has of the present invention is:
1, this type radio-frequency electromagnetic relay is a kind of miniature sealed direct-current electromagnetic relay, and its volume is little, and is in light weight, anti-vibration, impact property index height, low distributed capacitance.
2, the contact system of this type radio-frequency electromagnetic relay has special construction: one group of make contact (1H), two groups of break contacts (2D) are applicable to the circuit application of special switching mode.
3, this type radio-frequency electromagnetic relay radiofrequency characteristics (inserting loss, isolation, voltage standing wave ratio, radio-frequency power transmittability, characteristic impedance) parameter matching is good, and the radiofrequency signal that is widely used in (0～3) GHz frequency range is switched.
The invention has the beneficial effects as follows: satisfy special instructions for use, improve product radio frequency parameter performance.
Description of drawings: Fig. 1 is the vertical view of invention,
Fig. 2 is a front view of the present invention,
Fig. 3 is the right view of Fig. 2,
Fig. 4 is the circuit diagram of looking up of Fig. 2.
Among the figure: 1 base, 2 make contact, 3 break contacts, 4 reed parts, 5 reset reeds, 6 loop A, 7 core portion, 8 yokes, 9 cases, 10 relay boss, 11 coil B, 12 anodal exits, 13 negative pole exits, 14 left reed exits, 15 right reed exits, 16 left break contact exits, 17 right break contact exits, 18 make contact.
Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, elder generation's spot welding make contact 2 on base 1 then is welded in 3 of break contacts on the base in contact system, 4 of reed parts is welded on the base again, and the reset reed 5 of burn-oning at last forms contact portion; Loop A 6 and core portion 7, yoke 8 are assembled into the magnetic circuit part by the mode of revolving riveting, and at last contact portion and magnetic circuit partly being put postwelding becomes the relay part, and with case 9 sealings by fusing.
As shown in Figure 4, the relay working method is as follows, after giving anodal exit 12 of coil B11 and 13 energisings of negative pole exit, left side reed exit 14 and right reed exit 15 leave left break contact exit 16 and right break contact exit 17, all contact with make contact 18, left reed exit 14 and right reed exit 15 are communicated with, form one group of make contact, finish once and switch.After the outage, left reed exit 14 and right reed exit 15 leave make contact 18, contact with right break contact exit 17 with left break contact exit 16 respectively, recover two groups of break contact states.
