Embodiment
Accompanying drawing 1-6 has provided the utility model embodiment.The small-sized high-power sealed direct-current electromagnetic relay has 12, two fixed contacts 7 of base and is fixed on base 12 1 ends by the fixed contact frame, and moving contact 6 is between two fixed contacts; Its moving contact 6 usefulness movable contact springs 5 are fixed on push card 4 one ends, armature 2 is installed in push card 4 other ends and link can vertically move on push card, armature 2 other ends are positioned at jump ring 1 and can rotate around fulcrum 8, jump ring 1 is installed on the base 12, bobbin 9 be fixed on the base and yoke 3 mounted thereto.
The utility model architecture advances point mainly also comprises:
The magnetic circuit of a, this product partly is different from common iron core and yoke separate structure, but the two unification is designed to the magnetic conductor of U type yoke as the magnetic circuit part, the purpose of this design is to eliminate the inhomogeneous high magnetic resistance zone that riveting dress part unshakable in one's determination occurs in unshakable in one's determination and the yoke separate structure, coil working efficient is improved on the highland as far as possible, realizes the requirement of product low-power consumption;
B, electromagnetic system are designed to semi-surrounding structure (as Fig. 2), make between relay contact part and control coil and have very big creepage distance, to reach the purpose (the withstand voltage 5000Vr.m.s of reaching between coil and contact) that has high isolation strength between the relay input and output, satisfy the requirement of product high security;
C, between the contact of base design groove and boss (as Fig. 2), to increase the creepage distance between the contact, satisfy the security requirement of creepage distance between the contact;
D, because this product height dimension has significantly than the product of OMRON same specification reduces, therefore movable contact spring is designed to bending structure (as figure .3), in littler relatively space, increased the arm of force length of reed effectively, made the mechanics matching relationship of electromagnet portion and contact portion reach reasonable;
Use between e, movable contact spring and pin and turn over riveting and is connected, promptly guaranteed the tightness between reed and the pin, avoided pin again because mistake approaches the insufficient strength (as Fig. 4) that causes;
F, contact system and electromagnetic system do not use the riveting load to connect, but directly push-in type assembles, and have reduced the difficulty of the assembling of relay; And we have increased Ka Tai (as Fig. 5) on bobbin, closely cooperate with concave station on the base, have not only solved the pin orientation problem, and have guaranteed fitted position;
After improving on the utility model structure, its manufacture craft has also been done following corresponding improvement:
A, this product are higher to the yoke required precision, and require head concordant, and the technology during to part processing has increased difficulty.Originally use bending behind the blanking, carry out the method for topping again, but the part consistency of being processed is poor, and moving to discharge influence bigger to the suction of product to cut off the edge of a knife direction that produces.Consider this product needed batch process, the product end can't be used the method for grinding again, so we directly use the length after mould guarantees the yoke blanking, calculate suitable press-bending line position, directly bending behind the blanking both guaranteed the size of part, and consistency is higher after the part processing.
The armature part of b, this product is comparatively special, need extrusion molding, and deflection is bigger, it is thick the thick 1.3mm of material to be expressed to 0.5mm, all can adopt single operation production in the past, current then consider the production in enormous quantities of product, thus adopted progressive die to produce this part, make part shorten operation aborning, and guaranteed the consistency of part.
The product of making according to the utility model structure and technology contrasts in external product:
This product is similar to the G6RN product of Omron, realize 8A, 250Va.c. (wherein the JQX-131F DC load is 8A 30Vd.c. in the switching of load, the G6RN DC load is 5A30Vd.c.), environmental protection, low clearance, high withstand voltage, high insulation, and fail safe all meets European VDE authentication, and (following contrast model is: JQX-131F) product is than its highly low (Omron product height is 15mm, and JQX-131F highly is 12.4mm) with Omron product the utility model but compare, it is more simple and easy that internal structure is compared the Omron product, and concrete technical indicator contrast sees Table 1.
The key technical indexes of this product is as follows:
Table 1
Operation principle
This product adopts the clapper-type magnetic structure, when coil stimulating, under the effect of electromagnetic attraction, armature rotates (see figure 1) around fulcrum, drive the push card motion of hinge arrangement between yoke and the movable contact spring simultaneously, promote flexible movable contact spring motion, the moving contact that is installed on the movable contact spring also moves with the normally-closed contact disconnection and to normally opened contact thereupon, when armature contacts with yoke, relay driving process finishes, this moment, moving contact also arrived the contact position with normally opened contact, made moving contact and often switched on, and finished the course of action of relay; When coil stimulating disappeared, armature restored at the rubber-like movable contact spring under the effect of counter-force, promoted armature around the fulcrum rotation by push card, contact with normally-closed contact until moving contact, movable contact spring restores counter-force and disappears, and armature motion stops, and finishes the dispose procedure of relay.
