Embodiment
Figure 3 shows that the cutaway view of coil rack provided by the invention.Figure 4 shows that the enlarged diagram at circle C place in Fig. 3.Figure 5 shows that the enlarged diagram at circle D place in Fig. 3.Please also refer to Fig. 3 to Fig. 5.
The invention provides a kind of coil rack and comprise body 1, the first pointed shape sealed muscle 2, skeleton interface portion 3, seal bead 4 and the second pointed shape sealed muscle 5.Body 1 has top edge 11 and the lower limb 12 be arrangeding in parallel.Top edge 11 has the first groove 111, and lower limb 12 has the second groove 121 and the 3rd groove 122.
The first pointed shape sealed muscle 2 is around being arranged at top edge 11, the first pointed shape sealed muscles 2 towards lower limb 12 1 sides projections, and the tip height h1 of the first pointed shape sealed muscle 2 is no more than the face down apparent height h2 at edge of top edge 11.By this set, in the process of enamelled wire winding around skeleton, enamelled wire can be avoided the tip of the first pointed shape sealed muscle 2 smoothly, avoids damaging enamelled wire.The first groove 111 adjoins the inner side of the first pointed shape sealed muscle 2.
Skeleton interface portion 3 connects lower limb 12.In Fig. 3, skeleton interface portion 3 connects the right side of lower limb 12.
Seal bead 4 is located at the junction of skeleton interface portion 3 and lower limb 12, is right side in Fig. 3.Seal bead 4 is that inclined-plane 41, the three grooves 122 adjoin the side that seal bead 4 deviates from skeleton interface portion 3 near a side of skeleton interface portion 3, and seal bead 4 is towards a side projection that deviates from top edge 11.Because inclined-plane 41 has constant slope, filler 41 impacts the 3rd groove 122 to inner side along inclined-plane, outside, and in inner side, the 3rd groove 122 forms high-temperature areas, effectively melts seal bead 4, reaches waterproof effect.
In the present embodiment, the side that seal bead 4 deviates from skeleton interface portion 3 is vertical plane 42, the die sinking requirement while being convenient to manufacture by this set.In the present embodiment, seal bead 4 is 70 ° near the ramp angles on the inclined-plane 41 of skeleton interface portion 3.This angle is according to calculating, and under this angle, filler 41 flows along inclined-plane, and shock point just, in the 3rd groove 122, reaches the optimum efficiency of impact-absorbing power.In the present embodiment, seal bead is wedge shape.Yet the present invention is not limited in any way the shape of seal bead.In other embodiment, seal bead also can be pointed (triangle), and the side that seal bead 4 deviates from skeleton interface portion 3 is also inclined-plane, as long as guarantee that seal bead 4 is inclined-plane 41 near a side of skeleton interface portion 3.
The second pointed shape sealed muscle 5 is located at not connecting framework interface portion 3 places of lower limb 12, is left side in Fig. 3.In other embodiment, the second pointed shape sealed muscle 5 is not only arranged at not connecting framework interface portion 3 places of lower limb 12, can also be arranged at the junction of skeleton interface portion 3 and lower limb 12.In other words, the second pointed shape sealed muscle 5 can be around being arranged at lower limb.Consider the mechanical strength that improves lower limb 12 and skeleton interface portion 3 junctions, preferably, the second pointed shape sealed muscle 5 is only located at not connecting framework interface portion 3 places of lower limb 12.The second pointed shape sealed muscle 5 is towards top edge 11 1 side projections, and the tip height of the second pointed shape sealed muscle 5 is no more than lower limb towards the apparent height of top edge 11.By this set, in the process of enamelled wire winding around skeleton, enamelled wire can be avoided the tip of the second pointed shape sealed muscle 5 smoothly, avoids damaging enamelled wire.The second groove 121 adjoins the inner side of the second pointed shape sealed muscle 5.
In Fig. 3, the first pointed shape sealed muscle 2 and seal bead 4 are towards lower convexity, and the second pointed shape sealed muscle 5 is towards projection.The setting position of all pointed shape sealed muscles 2,5 of the present invention and seal bead 4 is that filler can produce to enamelled wire the place of impulsive force, to guarantee effectively impact-absorbing power of all grooves 111,121,122.
The wedge angle of the first pointed shape sealed muscle 2 and the second pointed shape sealed muscle 5 is by constant slope design, and filler Yan Liao road is impacted to the first groove 111 and the second groove 121.By the first pointed shape sealed muscle 2 and the second pointed shape sealed muscle 5 are set to pointed shape, in injection moulding process, high temperature filler easily merges wedge angle herein, thereby reaches the waterproof action of coil rack.
In one embodiment of the invention, body 1, the first pointed shape sealed muscle 2, seal bead 4 and the second pointed shape sealed muscle 5 adopt and plasticity PBT(polybutylene terephthalate (PBT)s) thermoplastic that material is identical makes.
Figure 6 shows that the cutaway view of expansion valve coil provided by the invention when assembling.Figure 7 shows that the enlarged diagram at circle E place in Fig. 6.Figure 8 shows that the enlarged diagram at circle F place in Fig. 6.Please also refer to Fig. 6 to Fig. 8.
The present invention also provides a kind of expansion valve coil to comprise two coil rack a ', enamelled wire i ', a plurality of contact pin b ', two stator plate e ' and stator casing (not shown).Coil rack a ' as mentioned above, repeats no more.Enamelled wire i ' is wound on two coil rack a '.A plurality of contact pin b ' are inserted in skeleton interface portion and weld with the end of a thread of enamelled wire i '.Two stator plate e ' are located in two coil rack a '.Coated two coil rack a ', the enamelled wire i ' of stator casing and two stator plate e '.
Expansion valve coil provided by the invention is when pressure injection, filler shock point can be due to the guiding on inclined-plane in the first pointed shape sealed muscle 2, the second pointed shape sealed muscle 5 and seal bead 4, and shock point is transferred to the first groove 111, in the second groove 121 and the 3rd groove 122 (as circle in Fig. 7 and Fig. 8 indicates), thereby effectively absorb the impulsive force that filler produces.
In sum, the present invention has overcome in conventional art for the solution enamelled wire power that withstands shocks is only improved enamelled wire and improvement coil rack is only the technology prejudice of waterproof action, adopt the thinking of innovation, by improving coil rack, gone to solve the be hit problem of power of enamelled wire.First, second pointed shape sealed muscle of coil rack protrusions of the present invention and seal bead guiding filler, first, second, and third groove has impact-absorbing power.In view of the fast feature of plastic material crystallization rate, after the buffering of first, second, and third groove, will effectively reduce the damage to enameled wire coat of the high temperature that brings when plastic material is filled, thereby improve coil quality, and without increasing any extra cost.In addition, seal bead and first, second pointed shape sealed muscle have good water-tight performance, improve the electrical insulation properties of product.
Although the present invention is disclosed as above by preferred embodiment; yet not in order to limit the present invention, anyly know this skill person, without departing from the spirit and scope of the present invention; can do a little change and retouching, so protection scope of the present invention is when being as the criterion depending on claims scope required for protection.
