Description
Technical field
The present invention relates to a kind of electromagnetic coil skeleton, more particularly, to a kind of lug plate and the coil bone with the lug plate
Frame.
Background technology
On the online ring framework of the usual coiling of electromagnetic coil, coil rack includes supporting rack and wire spool, the side of supporting rack
Connect lug plate.
At present common wiring chip architecture as shown in Figure 1, the fixed form of lug plate and coil rack as shown in Fig. 2, connecing
Line piece is with after coil rack interference fit, link piece is blocked by boss and location hole.But this structure clearly has as follows
Defect：
1st, lug plate and coil rack fixed form are unreliable, and lug plate is only limited by a convex closure and coil rack small area
Position, bears the torsion in incessantly screw tightening direction, and screwdriver tightening direction easily twists lug plate afterbody during product coil wiring
Go out, as shown in figure 3, arrow represents screw tightening direction in figure, lug plate, which is back-outed to have enameled wire, necessarily to be pullled, and is seriously caused
Enameled wire breaks；It is serious to influence product use to breaking.
2nd, lug plate and coil rack are elastic conjunction, and the convex closure on lug plate should not be too high, and due to technological problems,
The boss of convex closure can not make obvious step, can not ensure that boss blocks effective fixation with framework location hole；Fixation is unreliable,
Deviate from from fixing groove, cause enameled wire to break, contactor can not be attracted.
3rd, in lug plate assembling process, it can squeeze unit of plastic, these unit of plastics, will not be due to certain toughness at once
Drop, often drop after product is loaded because contactor is attracted the vibrations of release above mounting hole.So as to cause to be attracted noise
Or movement clamping stagnation, and then cause coil burnout or the catastrophe failures such as contact is burnt.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of lug plate and carry
The coil rack of the lug plate.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of lug plate, including location division and fastening part, the location division are used to be connected with coil rack, and described is tight
Gu portion is used to connect retaining mechanism, a side of the location division carries bending, and the bending is used for and coil rack
Sliding slot be slidably connected.
The bending and the contact surface of coil rack carry hangnail.
The fastening part is equipped with tapped through hole.
The fastening part surface carries anti-skid chequer, and the anti-skid chequer is arranged on tapped through hole both sides.
A kind of coil rack of the lug plate, including supporting rack and wire spool, it is characterised in that the supporting rack
With sliding slot, the bending of the lug plate is slidably connected with the sliding slot.
The bending and the contact surface of coil rack carry hangnail, and the hangnail is interference fitted with sliding slot.
The lug plate to supporting rack slide when, hangnail gradually increases with sliding slot shrink value.
The sliding slot is square groove.
Compared with prior art, the present invention has the following advantages：
(1) a side of lug plate location division carries bending, and bending is used to be slidably connected with the sliding slot on coil rack, rolls over
Bending process requirement is low, can increase contact area by improving the height of bending, so that the torsion ability to bear of lug plate is improved,
Screwdriver is not easy to shift when tightening screw, prevent because lug plate afterbody back-outs make enameled wire damage, pull apart caused by product lose
Effect, prevents the damaged unit of plastic produced of coil rack from coming off.
(2) contact surface of bending and coil rack carries hangnail, can produce interference fit, improve the fastening force of contact surface.
(3) fastening part surface carries anti-skid chequer, and when installation is convenient to be gripped.
(4) lug plate to supporting rack slide when, hangnail gradually increases with sliding slot shrink value, prevents lug plate from reversely skidding off.
(5) sliding slot is square groove, and manufacture cost is low.

Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to
Following embodiments.
Embodiment 1
As shown in figure 4, a kind of lug plate, including location division 11 and fastening part 12, location division 11 are used to connect with coil rack
Connect, fastening part 12 is equipped with tapped through hole 121, and tapped through hole 121 is used to connect retaining mechanism, such as screw, tapped through hole 121
Both sides sets anti-skid chequer 122；A side of location division 11 carries bending 111, and bending is used to slide with the sliding slot on coil rack
Connection.Bending 111 and the contact surface of coil rack carry hangnail 112.
Embodiment 2
As shown in figure 5, a kind of coil rack of lug plate, including supporting rack 21 and wire spool 22, supporting rack 21 is with side
The sliding slot 211 of shape, the bending 111 of lug plate carry hangnail 112, hangnail 112 and 211 interference of sliding slot with the contact surface of coil rack
Coordinate, lug plate to supporting rack 21 slides when, hangnail 112 gradually increases with 211 shrink value of sliding slot, prevents loose after lug plate assembling
It is dynamic, coiling abjection.
The present embodiment lug plate is spacing without boss with coil rack, increases folding surface in lug plate side, in coil bone
Increase a deep trouth in frame, it is spacing by large area, the torsion that screwdriver the turn of the screw tightening direction lug plate is born is born, is filled
Unit of plastic is not produced during matching somebody with somebody to come off, causes iron core noise so as to avoid since unit of plastic drops to iron core surface, or fall
Fall on movement clearance and cause movement clamping stagnation, and then cause coil burnout or the more serious failures such as contact is burnt.During terminal block,
Will not lug plate afterbody situation about back-outing, it is therefore prevented that make enameled wire damage because lug plate back-outs, pull apart caused by product failure.
