Description
Technical field
The utility model relates to field of motor manufacturing, especially a kind of electromagnetic coil skeleton with waterproof construction.
Background technology
Air-conditioning is used for the electric expansion valve of adjusting refrigerant flow rate comprises a valve part and an expansion valve coil.Control the flow of cold-producing medium with the needle opening degree in described coil drive valve part, thus reach the effect of control temperature.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 the work of energising, cool during power-off, in this operating state colded and heat succeed each other, the condensed water of coil surface usually can penetrate into coil inside and cause coil failure.In order to ensure the normal work of coil, just must prevent condensed water from infiltrating in coil.All the time, the waterproof sealing performance of coil just becomes a technical barrier.
Summary of the invention
The object of the utility model patent overcomes the deficiencies in the prior art, provides the better electromagnetic coil skeleton of a kind of water-tight performance.
For solving above technical problem, the utility model is realized by following scheme:
A kind of electromagnetic coil skeleton with waterproof construction, the connecting portion including the bobbin of " work " font, contact pin fixed part and be connected between bobbin and contact pin fixed part, the pin holes of level is provided with in described contact pin fixed part, within one week, annular groove is provided with in described bobbin outside, the outer shroud convex tendon of this annular groove lower than skeleton plane, and leaves outer step between outer shroud convex tendon and skeleton edges; The edge of described bobbin is being provided with fillet beyond inner; Described connecting portion outer surface is provided with horizontal step; The straight groove of " convex " font is provided with down in described horizontal step.
Compared with prior art, the beneficial effects of the utility model are: owing within one week, being provided with annular groove in bobbin outside, and the outer shroud convex tendon of this annular groove is lower than skeleton plane, and leaving outer step between outer shroud convex tendon and skeleton edges, when these are all conducive to injection moulding, the flowing of plastic cement is filled better, coated skeleton is peripheral; Described connecting portion outer surface is provided with horizontal step, the straight groove of " convex " font is provided with down in described horizontal step, when injection moulding, after solenoid being encapsulated in the straight groove of font that plastic cement flow into down " convex " and annular groove, the waterproof ability after injection encapsulated can be improved, thus substantially increase the water resistance of solenoid; And its compact conformation, improve Product Safety.
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:

Fig. 2 is the structural representation of the utility model embodiment;
Fig. 3 is the enlarged drawing of the local I of Fig. 2;
Fig. 4 is the enlarged drawing of the local I I of Fig. 2;
Fig. 5 is schematic diagram when the utility model being made solenoid under each step;
Fig. 6 is the structural representation (before injection moulding) of current electromagnetic coil.
[embodiment]
A kind of electromagnetic coil skeleton with waterproof construction, as shown in Figures 1 to 4, the connecting portion 3 including the bobbin 1 of " work " font, contact pin fixed part 2 and be connected between bobbin 1 and contact pin fixed part 2, the pin holes of level is provided with in described contact pin fixed part 2, within outside one week, annular groove 11 is provided with at described bobbin 1, the outer shroud convex tendon 12 of this annular groove 11 is lower than skeleton plane 13, and leaving outer step 14 between outer shroud convex tendon 12 and skeleton edges, when these are all conducive to injection moulding, the flowing of plastic cement is filled better, coated skeleton is peripheral; The edge of described bobbin 1 is being provided with fillet 15 beyond inner; Described connecting portion 3 outer surface is provided with horizontal step 31; The straight groove 32 of " convex " font is provided with down in described horizontal step 31, when injection moulding, after solenoid being encapsulated in the straight groove 32 of font that plastic cement flow into down " convex " and annular groove 11, the waterproof ability after injection encapsulated can be improved, thus substantially increase the water resistance of solenoid; And its compact conformation, improve Product Safety.
We know, existing control solenoid,---coiling---upper tin---bending (bending is again carried out in acupuncture treatment) that its production method is: coil holder contact pin, when the method for bending easily appears at bending contact pin after tin is first gone up in this employing, wire generation is pulled, cause the hidden danger of the conductor cord disconnection that there is upper tin position.For this reason, we are when making solenoid with electromagnetic coil skeleton above, adopt following steps, as shown in Figure 5:
1), straight line contact pin 4 is inserted in the pin holes 21 of electromagnetic coil skeleton;
2) contact pin 4 bending, will be plugged;
3), toward coiling 5 in bobbin 1;
4), overhang is wrapped on contact pin 4;
5), upper tin: namely carry out scolding tin process on the contact pin around coil.
In the 4th step above, the end of a thread around bobbin 1 inside conductor is along the surface of connecting portion 3 to be wound into the contact pin 4 on contact pin fixed part 2, vacant state can not be in like this at that section lead on connecting portion surface, impact so can not produce this section lead in follow-up injection molding process, also just reduce the stressed of this section lead to break, thus the generation of defective products when greatly reducing injection moulding.And current solenoid, as shown in Figure 6, height due to contact pin fixed part 2 is higher than the height of connecting portion 3, therefore that section lead 6 between contact pin fixed part 2 and connecting portion 3 forms unsettled section, in follow-up injection molding process, injection molding material produces unsettled section of wire and impacts, because this section lead 6 is unsettled without supporting, and the hot strength of wire is limited, the therefore easy situation bad at injection moulding process generation broken string.
