Description
Technical field
The present invention relates to a kind of electromagnetic relay, relate in particular to a kind of high-power magnetic relay with pushing mechanism.
Background technology
Relay is that one is used electronic component widely, and it is widely used in the fields such as household electrical appliance, automobile, Industry Control, electric power system, communication device, and its developing direction is microminaturization, high-power, chip type, highly sensitiveization, multifunction etc.Wherein electromagnetic relay is in high-power development, relay contact load is larger, the temperature rise of relay contact is just larger, and temperature rise is to affect one of key factor of relay electrical contact reliability, contact temperature rise strengthens and makes contact easily occur bonding and relay is quit work, thus relay particularly high power relay to solve the heat dissipation problem of relay contact.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high-power magnetic relay with pushing mechanism that can realize contact good heat radiating.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of high-power magnetic relay with pushing mechanism, comprise magnetic circuit part, contact portion, the pushing mechanism of the magnetic circuit part described in connecting and described contact portion, described contact portion comprises moving contact group and the quiet group that contacts, described moving contact group comprises moving contacting plate and moving contact, described quiet contact group comprises quiet contact chip and fixed contact, it is characterized in that described pushing mechanism comprises pushing block and elastic metallic reed, described elastic metallic reed comprises the connecting portion being wholely set, Access Division and roundabout portion for being connected described connecting portion and described Access Division, the connecting portion of described elastic metallic reed is fixedly connected with the top of described moving contacting plate, the phase clamping of the Access Division of described elastic metallic reed and described pushing block, described pushing block one end is provided with window, the top of described elastic metallic reed and described moving contacting plate is connected in the window of described pushing block.
The connecting portion of described elastic metallic reed amplexiforms fixing with the top of described moving contacting plate mutually, because elastic metallic reed carries out good contacting with moving contacting plate, elastic metallic reed can better conduct the relay heat that contact produces in the time working and distribute like this.
Described roundabout portion is V-shaped, and its v-angle is 40 ° ~ 60 °, now, pushing mechanism is realized best contact force and contact overtravel by the strain of elastic metallic reed, and center, contact Aligning degree the best when moving contact and fixed contact adhesive, thereby realize the best contact of sound contact, reduced the heating of contact, also further reduced contact temperature rise.
The connecting portion of described elastic metallic reed is wholely set and is useful on the first clamping being connected with described pushing block, the Access Division of described elastic metallic reed is wholely set the second clamping that is useful on described elastic metallic reed location in the time of assembling, so just facilitate the installation of elastic metallic reed, can make again the installation that obtains of elastic metallic reed locate.
The material of described elastic metallic reed is beryllium-bronze, and the good heat conductivility of beryllium-bronze and mechanical performance make that relay contact contacts well, temperature rise reduces and more excellent heat radiation, are the optimal selections of elastic metallic reed material.
The material of described pushing block is plastics, between described pushing block and described moving contact, described fixed contact, be provided with metal arc sheet, described metal arc sheet comprises the arc portion that is wholely set and the installation portion in order to install, and the installation portion of described metal arc sheet amplexiforms mutually with described moving contacting plate.In the time that the moving contact of relay and fixed contact produce arcing in dispose procedure, metal arc sheet absorbs heat heat radiation on the one hand, simultaneously by the arc light reflecting producing, both baffle plastics pushing block be subject to the direct calcination of arc light, reduced being again heated of plastics pushing blocks; On the other hand, metal arc sheet resistance shelves the bead that is melt into by the glass fibre in plastics pushing block splash, come off and bond on the dynamic and static contact of relay, and reduce the risk of the organic gaseous contamination contact of resin in plastics pushing block gasification, thereby it is good to have ensured that relay contact contacts in the time of work, reduce relay the probability losing efficacy occurs, and then ensured performance and the life-span of relay, and improve the reliability of relay work.
The front end of the arc portion of described metal arc sheet, to described plastics pushing block direction perk, so can better meet contact air gap requirement, can make again contact heat radiation better.
The arc portion of described metal arc sheet is to described moving contact and described fixed contact projection and be arc surfaced, can be the face of cylinder or sphere etc., like this when contact produces when arcing, the sector-meeting of metal arc is arc light and the outside scattering of heat, the heat radiation of contact got back and further improve.
The material of described metal arc sheet is beryllium-bronze.The heat conductivility that beryllium-bronze is good makes heat radiation more excellent, is the optimal selection of metal arc sheet material.
Compared with prior art, the invention has the advantages that: because the elastic metallic reed of pushing mechanism and the moving contacting plate top of contact portion are fixedly connected with, so the heat producing on moving contact can pass to elastic metallic reed by moving contacting plate, and elastic metallic reed comprise roundabout portion, in meeting contact force and contact overtravel, increased reed area of dissipation, the contact of relay has obtained good heat radiation, and then reduction contact temperature rise, simultaneously, the contact load ability of relay can correspondingly increase, and realizes the high-power of relay.
