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 utility model, 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 beneficial effects of the utility model are:
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 utility model 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 utility model 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 utility model is described in further detail; But a kind of unicoil magnetic latching relay of the present utility model is not limited to embodiment.
