Description
Technical field
It the utility model is related to relay, and in particular to a kind of pressure-resistant magnetic latching relay, belong to electrical product technology neck
Domain.
Background technology
Magnetic latching relay is a kind of new type of relay to grow up in recent years, and a kind of automatic switch, to circuit
Play turn on automatically and cutting action.
Its contact opening and closing state magnetic force as caused by permanent magnet of magnetic latching relay is kept, when touching for relay
Point needs are opened or during conjunction state, it is only necessary to just（Instead）DC pulse voltage excitation coil, relay just complete out in moment
With the State Transferring of conjunction；When usual contact is in hold mode, coil needs not continue to be powered, only by permanent magnet magnetic force just
The state of relay can be maintained constant；When the contact of relay needs set, it is only necessary to positive direct-current pulsed voltage excitation line
To enclose, the magnetic pole interaction of caused magnetic pole and permanent magnet after coil magnetization, same polarity is mutually exclusive, and heteropolarity attracts each other,
So that relay just completes the State Transferring for resetting to set in moment.
Traditional magnetic latching relay assembling, suture introducing needle need to be inserted on the base and top plate of bobbin, bobbin into
Need to set suture introducing needle mounting hole on base and top plate during type, suture introducing needle is interspersed in suture introducing needle mounting hole, and process is more, operation
Inconvenience, during practical set, often occur that suture introducing needle mounting hole is excessive or too small, and mounting hole is too big, and suture introducing needle easily swings pine
It is de-, and the installation gap of suture introducing needle and bobbin pieces so that during coil discharge, the voltage endurance capability of bobbin is remarkably decreased, and is held
Easily cause product and burn damage；Mounting hole is too small, and suture introducing needle is not easy to intert, installation inconvenience.
The content of the invention
In view of the deficienciess of the prior art, the utility model provides a kind of pressure-resistant magnetic latching relay, in realization
Purpose is stated, the utility model provides following technical scheme：A kind of pressure-resistant magnetic latching relay, including bobbin and suture introducing needle,
Two suture introducing needles are set wherein on the base of bobbin, a suture introducing needle are set on top plate, suture introducing needle is in bobbin injection molding
When place in a mold, after injection molding, bobbin and suture introducing needle are structure as a whole, and suture introducing needle center section is wrapped in bobbin
In plastics.
A kind of pressure-resistant magnetic latching relay described in the utility model, wherein suture introducing needle is by suture introducing needle body and limited block group
Into suture introducing needle body is the consistent colonnette of a thickness, and the position of colonnette about 1/3 sets a raised limited block, spacing
Block can be an annulus or a box structure so that suture introducing needle body is closely combined together with moulding.
A kind of pressure-resistant magnetic latching relay described in the utility model, wherein the suture introducing needle body cross-section can the side of being
Shape, rectangle, polygon, circle or ellipse.
Following beneficial effect is produced using the technical program：
In technical scheme provided by the utility model, suture introducing needle and bobbin use integrative-structure, eliminate traditional assembling
Installation gap in mode between suture introducing needle and bobbin lead mounting hole, when avoiding coil discharge, suture introducing needle position is produced
Rush of current, improve the proof voltage grade of bobbin；Using suture introducing needle and bobbin injection one-shot forming technique, simplify
Processing technology, reduce assembly process, optimize flow, improve efficiency of assembling and product quality.
The utility model is further described below in conjunction with the accompanying drawings.
Brief description of the drawings

In figure：1 bobbin, 11 bases, 12 top plates, 2 suture introducing needles, 21 suture introducing needle bodies, 22 limited blocks.
Embodiment
The utility model embodiment provides a kind of shock-proof relay, and Fig. 1 is a kind of pressure-resistant magnetic of the utility model embodiment
Guard relay structural representation one, Fig. 2 are a kind of pressure-resistant magnetic latching relay structural representation two of the utility model embodiment,
A kind of pressure-resistant magnetic latching relay of the present embodiment, including bobbin 1 and suture introducing needle 2, are wherein set on the base 11 of bobbin 1
Two suture introducing needles 2, a suture introducing needle 2 is set on top plate 12, and suture introducing needle 2 is placed in a mold in 1 injection molding of bobbin, noted
After being moulded into type, bobbin 1 and suture introducing needle 2 are structure as a whole, and the center section of suture introducing needle 2 is wrapped in the plastics of bobbin 1, are eliminated
Installation gap in traditional assembly method between suture introducing needle 2 and the lead mounting hole of bobbin 1, so avoids coil discharge
When, to rush of current caused by the position of suture introducing needle 2, improve the proof voltage grade of bobbin 1；Using suture introducing needle 2 and bobbin 1
One-shot forming technique is molded, processing technology is simplified, reduces assembly process, optimize flow, improve efficiency of assembling and production
Quality.
A kind of pressure-resistant magnetic latching relay of the utility model embodiment, wherein suture introducing needle 2 are by suture introducing needle body 21 and limit
Position block 22 forms, and suture introducing needle body 21 is the consistent colonnette of a thickness, and the position of colonnette about 1/3 sets a raised limit
Position block 22, limited block 22 is a square so that suture introducing needle body 21 is closely wrapped in one with the bobbin 1 of injection
Rise.
A kind of pressure-resistant magnetic latching relay of the utility model embodiment, wherein the cross section of the suture introducing needle body 21 is
It is circular.
The present embodiment is merely to illustrate the utility model and is used, and is not to limitation of the present utility model, the art
Those of ordinary skill corresponding deformation and modification can also be made in essential scope of the present utility model, so any equivalent
