Abstract
The invention discloses a single-coil magnetic latching relay which comprises a magnetic circuit part. The magnetic circuit part comprises a coil rack, a steel magnet, an iron core and a yoke iron. The iron core is inserted into a center hole of the coil rack. One coil rack end corresponding to the center hole is provided with a groove. One side of the yoke iron abuts and is fixed on the coil rack end provided with the groove. The steel magnet is accommodated in the groove and placed between the iron core and the yoke iron. One side of the yoke iron is provided with a first through hole for glue dispensing. The end face on one end of the coil rack is provided with a glue guide tank. One end of the glue guide tank is communicated with the first through hole while the other end leads to the groove. By arranging the glue dispensing hole and the glue guide tank, the relay makes the steel magnet firmly fixed and thus prevents problems caused by loosening of the steel magnet. Easy glue dispensing operations and accurate glue dispensing positions are achieved. Meanwhile, the relay itself and an operating platform will not be easily polluted during a glue dispensing process.
Description
Technical field
The present invention relates to a kind of electromagnetic relay, particularly relate to a kind of unicoil magnetic latching relay.
Background technology
Magnetic latching relay is a kind of new type of relay grown up in recent years, is also a kind of automatic switch.Magnetic latching relay is the same with other electromagnetic relays, plays automatically connect and cutting action circuit.Difference is, the normally closed or normally open of magnetic latching relay is the effect relying on permanent-magnet steel completely, and the conversion of its on off state leans on the pulse electrical signal of one fixed width to trigger.
The unicoil magnetic latching relay of prior art, two kinds are mainly contained to the fixed form of magnet steel, one adopts magnet steel to clamp fixing, the fixed form that clamps this magnet steel easily causes magnet steel to loosen, exist and cause relay parameter unstable, and the dimensional accuracy of part is difficult to control, the problems such as bad processing.Another kind is the fixed form adopting magnet steel point glue, this magnet steel point glue fixed form, due to be directly by glue point on magnet steel, a glue operation can be caused like this to be not easy, and easily to make the drawbacks such as glue stain relay itself and operating platform.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art, provide a kind of unicoil magnetic latching relay, by glue hole, set-point and draw glue groove, what both achieved magnet steel is stable fixing, avoids magnet steel and loosens brought drawback; Have again a glue processing ease, some glue position is accurate, is not easy the feature polluting relay itself and operating platform during point glue.
The technical solution adopted for the present invention to solve the technical problems is: a kind of unicoil magnetic latching relay, comprises magnetic circuit part; Described magnetic circuit part comprises bobbin, magnet steel, iron core and yoke; Iron core is inserted in the centre bore of bobbin; The bobbin corresponding to centre bore one end is being provided with groove, and reeded bobbin one end is established in reclining and being fixed on of yoke, and described magnet steel to be contained in described groove and to be placed between iron core and yoke; Described yoke while be provided with the first through hole for a glue, the end of described bobbin one end is provided with draws glue groove, described in draw glue groove one end be connected with described first through hole, described in draw glue groove the other end lead to described groove.
Described groove is made up of the first groove stacked together and the second groove, and wherein, the first groove is connected to described centre bore one end; One end of described iron core fits in described first groove, and described magnet steel fits in described second groove.
One end of described iron core has head, and the head of iron core is stuck in described first groove.
The described bottom land drawing glue groove is set to inclined-plane.
The end of described bobbin one end is also provided with at least one air discharge duct, and one end of air discharge duct is led to outside bobbin, and the other end passes to described groove.
One side of described yoke is also provided with several the second through holes, the end of described bobbin one end is also provided with several convex buds, the each convex bud of the described bobbin merga pass hot melt that matches with corresponding second through hole of yoke respectively scalds riveting technology, the plastics melting of the convex bud of yoke second through hole will be engaged in, make convex bud scald riveting in yoke second through hole, yoke and bobbin are fixed.
A kind of unicoil magnetic latching relay of the present invention, is on yoke, have a glue hole (i.e. the first through hole), bobbin is provided with and draws glue groove and air discharge duct (i.e. air-vent).When after energized relay circuit assembling, when glue, a glue is carried out in some glue hole dispensing needle head being goed deep into yoke, after glue is clicked and entered by a glue hole, namely enter and draw glue groove, drawing glue groove is a surface groove, draws the junction that glue can be caused iron core, magnet steel, yoke and bobbin by glue groove, namely specific, want the position fixed, they to be fixed.Owing to having a glue hole on yoke, simple to operate, be also not easy to make glue stain work top; And draw the existence of glue groove, smoothly glue can be introduced specific position, glue stain relay also can not be made inner.
The invention has the beneficial effects as follows:
1, due to have employed at yoke while be provided with the first through hole (namely put glue hole) for a glue, what be provided with correspondence in the end of bobbin one end draws glue groove, by glue hole, set-point and draw glue groove, both achieved and the stable of magnet steel had been fixed, and avoided magnet steel and loosen brought drawback; Have again a glue processing ease, some glue position is accurate, is not easy the feature polluting relay itself and operating platform during point glue.
2, the present invention increases a some glue hole at yoke, when glue, is convenient to a glue operation like this; Due to an existence in glue hole, when glue, glue stain operating platform and relay can be avoided; In addition, punching on yoke, part is easy to make, and cost is also relatively low.
3, the present invention draws glue groove in bobbin increase, glue can be drained into specific position, glue can be avoided everywhere to flow, produce and pollute during point glue; In addition, solation, to the specific position wanted, can make a glue accurate; Draw glue groove and air-vent is made on coil holder, be convenient to the making of part.
Below in conjunction with drawings and Examples, the present invention is described in further detail; But a kind of unicoil magnetic latching relay of the present invention is not limited to embodiment.
