Abstract
The utility model discloses a coil framework structure which comprises an upper edge and a lower edge, wherein stitches are connected at one edge where a wave-shaped protruding rib higher than the edge surface and the stitch position is arranged, bosses no lower than the wave-shaped protruding rib arranged on two sides of the wave-shaped protruding rib are arranged at the edge, and the end surfaces of the bosses are flat and level. The protruding rib is provided with a plurality of layers of sharp corners formed by continuous wave fluctuation, materials of the sharp corners can be molten along with high temperature during hot injection molding, and combining sealing performance of plastics and a framework cannot be affected due to damage of a certain point of the protruding rib. Therefore, product waterproof performance is further enhanced, plastics can be thoroughly fused with the framework during injection molding, and product performance and quality are greatly improved.
Description
Technical field
The utility model relates to a kind of coil skeleton structure, especially the skeleton structure of coil of electronic expansion valve.
Background technology
The electric expansion valve that on air-conditioning, is used for regulating refrigerant flow comprises a valve part and an expansion valve coil.Needle folding degree through in the coil drive valve part is controlled the flow of cold-producing medium, thereby reaches the effect of control temperature.Because the expansion valve coil is to be contained in off-premises station, in the use of air-conditioning refrigerant, usually can produce condensed water on the surface of valve body and coil.And coil generates heat when energising work, cools off during outage, and in this operating state that colds and heat succeed each other, the condensed water of coil surface usually can be penetrated into coil inside and also cause coil to lose efficacy.
In order to guarantee the operate as normal of coil, the waterproof sealing performance of coil becomes a technical barrier.The skeleton that the patent No. 201020527995.4 provides is processed with thermoplastic, and this skeleton structure is to increase clip slot and groove in the zone of the easiest infiltration, and (clip slot and groove only are that plastic packaging material is filled into though this structure can be strengthened the sealing of coil to a certain extent; Increase the seal distance of sealing surface, increased the infiltration distance of condensed water, played retarding action; Skeleton and injection molding material can not thoroughly merge); Like long-term use, during the state of condensed water long-term accumulated, waterproof effect is unsatisfactory.The insulation property of coil and useful life all can not reach perfect condition.
Summary of the invention
The utility model provides a kind of electrical insulation properties that can effectively improve product for solving the problem that prior art in use exists, and has the loop construction of extremely good water-tight performance.
The technical scheme that the utility model solves existing issue is a kind of coil skeleton structure; Comprise upper and lower two edges; Be connected with stitch on the described one edge, as improvement, the one edge of described connection stitch is provided with the waveform convex tendon that is higher than this edge surface and stitch place; Described waveform convex tendon both sides are positioned at this edge and are provided with the boss that is not less than the waveform convex tendon, and described raised head face is smooth.
As further improvement, described waveform convex tendon is continuous waveform convex tendon.
As further improvement, described waveform convex tendon is roughly the tip-angled shape of M shape; Above-mentioned boss is higher than the waveform convex tendon.
The utility model compared with prior art; Through being provided with the waveform convex tendon that is higher than this edge surface and stitch place in the one edge that connects stitch, waveform convex tendon both sides are positioned at this edge, and to be provided with its beneficial effect of boss that is not less than the waveform convex tendon be prevent effectively that sealing infiltrates skeleton inside; The smooth boss of waveform convex tendon both sides can effectively reduce the damaged combination seal property that influences injection molding material and skeleton of the skeleton convex tendon that causes because of carrying, transportation; And convex tendon has continuous heaving of the sea and the multilayer wedge angle that forms, and the material of wedge angle can thoroughly combine with plastic packaging material with high temperature melt in hot injection moulding
,Because temperature decline is very fast, have only this moment tiny wedge angle could guarantee to melt during injection moulding.Big more thick more just being difficult to melted.If this sharp edges is impaired, or sharp-pointed inadequately, then promptly can produce the result who is difficult to melt in hot injection moulding; Condensed water promptly can take place infiltrate skeleton inside, water resistance descends, and quality is difficult to guarantee; And effectively increased the infiltration distance of sealing area and condensed water, can be because of the damaged combination seal property that influences injection molding material and skeleton of certain some convex tendon, so the water resistance of product is further strengthened; Injection molding material can thoroughly merge with skeleton when injection moulding, has promoted performance of products and quality greatly.
