Description

Electromagnetic valve coil
Technical field
The present invention relates to the coil of cooling air conditioner solenoid valve, specifically a kind of coil rack, encapsulated layer adopt returnable thermoplastic, and it is about 105 ℃ and the coil of the lower material of price that the lead-in wire crust adopts heat resisting temperature.
Background technique
At present, in refrigerated air-conditioning system, be extensive use of various solenoid valves as Automatic Control Component, and solenoid plays an important role in solenoid valve as the control section of solenoid valve.Structural analysis from solenoid mainly comprises: (as shown in Figure 6) such as skeleton, enameled cable winding, the outer field encapsulated layer of winding, lead-in wires.But because the operating environment condition of coil is abominable, need carry out good insulation to the enameled cable winding, and require the covering of lead-in wire to have the good insulation performance performance, therefore use encapsulated layer to be encapsulated in outside the enameled cable winding, the part that also will go between is simultaneously coated.Yet since below the defective that exists of the prior art addressed, cause existing solenoid defectives such as waste material, poor sealing performance, cost height even befouling environment in the mill:
One, cooling air conditioner electromagnetic valve coil enclosure layer and lead wire insulation material commonly used
The outer field enclosure layer of widely used winding has epoxy resin and unsaturated resin two classes in the refrigeration air-conditioner electromagnetic valve coil at present, but their common drawback is slitter edge of producing in the production process etc. can't be reclaimed, reuse, and causes the waste of material and the pollution of environment easily.The molding for epoxy resin complex process with lead-in wire sealing difficulty, needs to adopt special organic glue to seal in addition.
The insulating material of widely used lead-in wire crust in coil mainly contains polyolefin and PVC (PVC) two classes at present.TPO its advantage that goes between is that heat resisting temperature is higher, is generally 125 ℃, and elasticity is better simultaneously, but its price is higher relatively.And PVC (PVC) class lead-in wire, though its price is relatively low, yet its heat resisting temperature is also lower, is generally 105 ℃, and is at high temperature aging easily; Simultaneously, its hardness is bigger, and elasticity is relatively poor.
Two, present common refrigeration air-conditioner electromagnetic valve coil type
Widely used coil often has two classes in the refrigeration air-conditioner solenoid valve at present, sees the 1st class and the 2nd class coil of following table for details:
Sequence number Coil method Forming method
Encapsulating material Framework material Lead-in wire outer layer insulation material The lead-in wire heatproof
The 1st class Epoxy resin Unsaturated resin Polyolefin 125℃ Embedding
The 2nd class Unsaturated resin Unsaturated resin Polyolefin 125℃ Seal
The 1st class coil, its major defect is: 1, moulding process is numerous and numerous and diverse, causes cost of production higher; 2, after coil is scrapped, epoxy resin is difficult for reclaiming use, causes environmental pollution easily; 3, the outer field insulating material of lead-in wire must adopt the higher TPO of price, can not directly seal between lead wire insulation material and the epoxy resin, must use special organic solvent glue sealing simultaneously; If the outer field insulating material of lead-in wire adopts more cheap PVC, can cause going between and encapsulating material between poor sealing.
The 2nd class coil, its major defect is: 1, Master Cost costliness, most of dependence on import, and homemade unsaturated resin, performances such as sealing are still unstable; In the coil forming process, waste material, material handle can't reclaim use simultaneously, and waste of material is bigger; 2, after coil is scrapped, unsaturated resin can't reclaim use, can pollute 3 to environment, can't merge between coil rack and the coil encapsulating material, causes problems such as poor sealing easily; 4, because the sealing between lead-in wire and the encapsulating material is an elasticity of utilizing the insulating material of lead-in wire, lead-in wire is contacted with encapsulating material tight realize, thereby the lead wire insulation material that has determined the coil of the type must use elasticity TPO preferably, and can not use relatively cheap but the PVC (PVC) that elasticity is relatively poor of price; Otherwise poor sealing with encapsulating material will cause going between.
Except the reason of above-mentioned material aspect, because of the defective of loop construction aspect also causes the coil poor sealing performance, end face as skeleton is the plane (see figure 7), even the encapsulated layer end face that covered skeleton still exists steam to pass through the possibility that the gap between encapsulated layer and the end face enters winding as shown in Figure 6 thus, at least under schematic structure, the path that steam passes through is than short.
Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes above-mentioned prior art, provides a kind of and can guarantee coil rack and encapsulated layer, encapsulated layer and lead-in wire good seal, and lead-in wire outer layer insulation material is not by aging low-cost coil.For this reason, the present invention is by the following technical solutions:
A kind of electromagnetic valve coil, comprise skeleton, the enameled cable winding on the skeleton, be encapsulated in the encapsulating material of winding outside and the lead-in wire that links to each other with enameled cable one end, the encapsulated material of the part of lead-in wire coats, it is characterized in that described skeleton and encapsulating material all adopt thermoplastic to make, the insulated hull of lead-in wire adopts the PVC material to make.
As the further of technique scheme improved and replenish, the present invention also comprises following additional technical feature:
In order to overcome the defective of existing product poor sealing performance from structure, the end face of described skeleton is provided with the path extending structure.Described path extending structure is the annular groove that is opened on the described skeleton end face.
Described winding is provided with false boss with the position of lead-in wire transition.
Electromagnetic valve coil of the present invention, its skeleton and encapsulating material have adopted thermoplastic; The outer layer insulation material of its lead-in wire has adopted the relatively cheap PVC material of price.Because skeleton and encapsulating material have adopted thermoplastic; thereby be, expect that the use second time of handle, waste material becomes possibility, not only reduced the use amount of material, reduced the cost of material of coil; also provide convenience simultaneously, be beneficial to the protection of environment for the recycling of coil after scrapping.Because the outer layer insulation material of lead-in wire has adopted the lower PVC material of price, makes the cost of coil that bigger reduction arranged.
Electromagnetic valve coil of the present invention, the end face of its coil rack is designed to concaveconvex structure, strengthening combining between skeleton and the coil encapsulating material, thereby has guaranteed good sealing effect.
Electromagnetic valve coil of the present invention, its lead-in wire and the transition part of coil encapsulating material, design has a false boss, by this boss, for the part cooling of the outer field insulating material that goes between provides may; This false boss volume is less simultaneously, and heat energy is also less when coil molding, thereby to avoiding the aging of outer field insulating material that go between, has played positive effect.
The present invention produces coil rack, seals by the thermoplastic that adopts recyclable utilization, uses the material of the PVC material of low price as the lead wire insulation layer, makes the cost of coil obtain significantly reducing.By the labyrinth groove is set on skeleton, the sealability of coil is guaranteed simultaneously.By design on coil false boss is arranged, prevented the aging of outer field insulating material that go between.Finally realized the effect of electromagnetic valve coil low cost, high performance-price ratio.

Embodiment
Coil shown in Fig. 1,4,5, its skeleton 5 and encapsulated layer 4 adopt thermoplastic (being also referred to as the abbreviation of PBT:Polybutylene Terephthalte) to make, and the insulated cladding of lead-in wire 1 adopts PVC (PVC).Because thermoplastic has the characteristic of " heating and melting → cooling curing → heating and melting, and its material behavior remains unchanged substantially ", therefore at the production line ring framework with seal the slitter edge, the material handle that produce in the forming process and all can be used as feed back and reuse.According to statistics, only this measure just can be saved PBT material 15%.In addition, because of the lead wire insulation material changes the lower PVC of price into from the higher polyolefin of price, make the cost of material of lead-in wire reduce nearly 30%.Thereby it is minimized to have realized that coil method uses, the effect of minimization of cost.
See Fig. 2, Fig. 3, its skeleton 5 one end faces are provided with the groove 7 of an annular, and the groove 6 of three annulars is set in the other end.By these grooves, to strengthen skeleton 5 and enclosure layer 4 mutual crosslink, water is limpened (as Fig. 4) from the distance that the coil outside enters winding, also increased water simultaneously and entered total distance of coil inside, thereby guaranteed the sealability between skeleton and the coil encapsulated layer.
In order to realize the sealing between encapsulated layer 4 and the lead-in wire 1, it is thermoplastic about 260 ℃ that encapsulating material 4 has been selected injection temperature for use, and 1 insulating material that goes between to have selected heat resisting temperature for use be 105 ℃ PVC (actual melt temperature is 160 ℃), realizing the mutual fusion of outer field insulating material of lead-in wire and encapsulating material, thereby guaranteed the excellent sealing performance between lead-in wire and the encapsulating material.
Coil shown in Fig. 1,4,5, at the transition part of lead-in wire with encapsulated layer, design has a false boss 2, the effect of this false boss mainly contains 2 points: 1, by this boss, optimized the moulding process of coil, promptly when coil molding, can set up a cooling unit at the boss corresponding position, reduce the temperature at boss position greatly, thereby the outer field insulating material of lead-in wire is farthest protected; 2, this is guaranteed under the prerequisite of boss intensity, makes the boss size as far as possible little, thereby makes boss localized heat energy minimization, and this is aging to the outer field insulating material of prevention lead-in wire, has also play a part positive.
