Abstract
A miniature sealed radio frequency electromagnetic relay consists of a contact part, a magnetic path part and a relay part, wherein a normally open contact (2), a normally closed contact (3), a reed part (4) and a restoring reed (5) are welded on a base (1) in a contact system, so that the contact part is formed; the magnetic path part is formed by assembling a coil A (6), an iron core part (7) and a yoke iron (8) through a rotary riveting manner; and finally the relay part is formed by the spot welding of the contact part and the magnetic path part and is fused and heat sealed with a cover piece(9). The relay has the advantages of small size, light weight, high shock and impact resistant performance index, and low distributed capacitance, has the contact system with a special structure and is applicable to circuit application with a special switching manner.
Description
Technical field: the utility model 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 utility model is that existing contact system structure is carried out the uniqueness design, 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 utility model: by contact portion, magnetic circuit part and relay are partly formed, and weld make contact, break contact, reed part and reset reed on the base in contact system, form 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 the utlity model has 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 beneficial effects of the utility model are: satisfy special instructions for use, improve product radio frequency parameter performance.

Fig. 2 is a front view of the present utility model,
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, welding make contact 2, break contact 3, reed part 4 and reset reed 5 form contact portion on the base 1 in contact system; 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.
