Description
Technical field
The utility model belongs to technical field of motors, relates to a kind of operator guards of motor wiring pin, particularly a kind of operator guards of plastic packaging motor wiring pin.
Background technology
Plastic packaging motor adopts plastic package technology to adopt engineering plastics to carry out the motor of overall package stator core, stator winding etc., can cancel traditional motor stator insulated treatment process and the metal chassis of common electric machine.Owing to have employed overall envelope molding technology, the compact structure of plastic packaging motor, exquisite appearance, good airproof performance, can effectively dust-proof, waterproof, grease proofing, reduce electrical fault rate.Because motor is when sealing molded, need high temperature high heat that solid is moulded product and be fused into liquid, the envelope be fused into time shaping is moulded liquid and to be under pressure extruding, liquid flows out from motor lead-out wire position, stick in wiring pin, cause the stitch of wiring pin to weld motor lead-out wire, become defective item, thus add motor manufacturing cost.
By being arranged with protective jacket on the exit of stitch in prior art; envelope can be avoided during encapsulation to a certain extent to mould liquid adhesive in wiring pin; because protective jacket is that directly cover is set in wiring pin; shake upset is there is during encapsulation; protective jacket is come off from wiring pin; do not reach the object of protection wiring pin, protected effect is poor.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the operator guards of the good plastic packaging motor wiring pin of protected effect of a kind of reasonable in design, butted line pin.
The purpose of this utility model realizes by following technical proposal:
The operator guards of this plastic packaging motor wiring pin, wiring pin comprises and is fixed on junction block on motor stator and some stitch be located in junction block, described operator guards comprises body, this body has the sealing surface be sealed and matched with the lateral surface of junction block, described sealing surface have some accommodation holes stretching out junction block part for holding stitch arranged with stitch one_to_one corresponding, it is characterized in that, the sidepiece of accommodation hole described at least one has the spacing hole be arrangeding in parallel with this accommodation hole and extend to sealing surface place, described spacing hole is crossing with its corresponding accommodation hole, the disconnecting prevention structure for preventing stitch from coming off in accommodation hole is provided with in described spacing hole.
In the operator guards of above-mentioned plastic packaging motor wiring pin, two accommodation hole sidepieces being positioned at body center all have parallel with this accommodation hole and extend to the spacing hole at sealing surface place, are equipped with disconnecting prevention structure in each described spacing hole.
In the operator guards of above-mentioned plastic packaging motor wiring pin; described disconnecting prevention structure comprises and is located in the push rod parallel with stitch in spacing hole and its inner be arranged on body sidewall and is resisted against set screw on push rod, and push rod described under the effect of this set screw is resisted against on stitch.
In the operator guards of above-mentioned plastic packaging motor wiring pin, the inner set screw be resisted against on same push rod is two, and the set screw described in two is uniformly distributed along spacing hole.
In the operator guards of above-mentioned plastic packaging motor wiring pin, described push rod has towards the inclined guide surface of stitch near one end of junction block.
Body in this operator guards is made up of high temperature resistant silicon glue material; before motor envelope is moulded, the accommodation hole on body faced toward stitch and be nested on stitch; after the sealing surface of body and the lateral surface of junction block seal and fit; screw set screw; make push rod against on stitch; under the effect of this push rod and accommodation hole madial wall, stitch is fixed, thus reach the fixing object of body.At push rod, spigot surface is set near one end of junction block, facilitates the insertion of stitch, can be sheathed fast, effectively save the set-up time.
Compared with prior art; the operator guards of this plastic packaging motor wiring pin has the following advantages: on stitch, overlap the body that high temperature resistant silicon glue material is made; prevented stitch from coming off in body by disconnecting prevention structure when stitch is located in after in body; efficiently solve stitch is moulded liquid adhesion phenomenon by envelope; body is reusable; and its structure is simple, economical and practical, improves rate of finished products, reduce the manufacturing cost of motor.

Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Wiring pin as shown in Figure 2 comprises and is fixed on junction block 11 on motor stator and some stitch 12 be located in junction block 11.
As shown in Figure 1; operator guards comprises body 2; this body 2 has the sealing surface be sealed and matched with the lateral surface of junction block 11; sealing surface have some accommodation holes 21 stretching out junction block 11 part for holding stitch 12 arranged with stitch 12 one_to_one corresponding; the sidepiece of at least one accommodation hole 21 has the spacing hole 22 be arrangeding in parallel with this accommodation hole 21 and extend to sealing surface place; spacing hole 22 is crossing with its corresponding accommodation hole 21, is provided with the disconnecting prevention structure for preventing stitch 12 from coming off in accommodation hole 21 in spacing hole 22.
