Description
Technical field
The present invention relates to electronic device, particularly a kind of normally open relay for automobile.
Background technology
Midget relay is the electronic device of a kind of extensive use on the automobile, for versatility and the interchangeability that improves relay, improve the reliability of vehicle electrical systems, international standard (ISO-7588-3-1998) road vehicle one electrical equipment/electronic switching device the 5th partly; Midget relay has carried out standard to overall dimension, pin shaped position and the function of relay for automobile, has also stipulated three kinds of function ways of realization: normally closed relay, normally opened relay and switching relay.But, along with the high speed development of Hyundai Motor, normally open relay for automobile is had higher requirement, as load big (20AVDC), driving power little (1.1W) etc., thereby produced the difficult new problem of super-high-current heat radiation.Existing relay (rope DENSO steps in Japan as shown in Figure 1), its reed 8 ' be riveted on yoke 10 ' on, and yoke 10 ' be enclosed in shell 16 ' in, be difficult for heat radiation; Resistance 13 ' be inlaid in base 14 ' input pin 1 ' on, the little assembling difficulty in space, coil 15 ′ De Chan systems and lead-out wires of coil and input pin 1 ' molten weldering between adorn operations every a plurality of rivetings, making troubles to production management also influences coil and twines the system quality.These problems all must be improved element design, internal structure, the assembly technology of existing relay.
Summary of the invention
The present invention has relay super-high-current poor radiation, the complicated existing technical problem of assembly technology now in order to solve, and develops a kind of normally open relay for automobile of new internal structure.
According to above-mentioned purpose, the invention provides a kind of normally open relay for automobile, comprise electromagnetic mechanism and be connected base and shell; Wherein electromagnetic mechanism is made up of moving contact, armature, reed, yoke, skeleton, iron core, coil; Wherein connect two input pins, the moving contact output pin of base by coil, fixed contact output pin, fixed contact, margining tablet, resistance, base are formed.
Wherein input pin is made of pin, brace; The upper end of pin is two bifurcated one resistor cartridges, down-lead bracket, but the recess setting-in resistance of resistor cartridge upper end, down-lead bracket upper end bending, the perpendicular end of brace that is the T font is the riveted joint sheet, horizontal end is a bonding pad, riveted joint sheet and the bending riveted joint of down-lead bracket upper end, bonding pad can weld the lead-out wire of coil.
The reed that wherein is the L font is riveted with moving contact, armature respectively on one side, its another side and moving contact output pin riveted joint, moving contact output pin and yoke riveted joint.
Said apparatus, wherein dynamic and static contact output pin adopts pure copper material to make.
The present invention is owing to taked above technical measures, existing miniature normally open relay for automobile is improved, solved the poor radiation problem of heavy load super-high-current, adjusted the assembly space of internal structure, simplified manufacturing process and production management, effect is fairly obvious.

Embodiment
Be the full sectional view of a kind of normally open relay for automobile of the present invention as shown in Figure 2, to ask its internal structure of clear expression, it comprises electromagnetic mechanism and is connected base and shell 16 that wherein electromagnetic mechanism is made up of moving contact 6, armature 8, reed 9, yoke 10, skeleton 11, iron core 12, coil 15; Wherein connect two input pins 1 and 2 of base by coil 15, moving contact output pin 3, fixed contact output pin 4, fixed contact 5, margining tablet 7, resistance 13, base 14 are formed.The structure of various relays is basic identical, and components and parts and connected mode thereof that it is detailed repeat no more, and below innovation part of the present invention is further elaborated.
The reed 9 that wherein is the L font on one side respectively with moving contact 6, armature 8 riveted joints, its another side and 3 riveted joints of moving contact output pin, moving contact output pin 3 is riveted with yoke 10; Wherein dynamic and static contact output pin 3,4 adopts pure copper material to make.The large load current of existing relay is mainly by yoke 10 heat radiations, and output pin 3,4 directly with extraneous air connect can, make internal heat be delivered to the outside as early as possible and go, the while thermal conductance of copper is much better than iron.
Be the stereogram of existing normally open relay for automobile input pin as shown in Figure 3.In conjunction with shown in Figure 1, its input pin 1 ' brace 1-2 ' at right angles be connected with pin 1-1 ', and be positioned at coil 15 ' the below, but the front end of brace 1-2 ' has two bifurcateds that at right angles connect with it---resistor cartridge 1-2-1 ' setting-in resistance 13 ', down-lead bracket 1-2-2 ' can weld coil 15 ' lead-out wire.There is following problem in this structure: the one, resistance 13 ' assembly space very little, operating difficulties; The 2nd, lead-out wire be welded to input pin 1 ' on be to connect last procedure that the base assembling is finished, middle input pin in addition, the operations such as riveted joint of output pin, fixed contact, like this with regard to cause easily coil 15 ' coiling loose, resistance value can not be measured immediately; The 3rd, the welding of coil 15 ′ De Chan systems and its lead-out wire can not be finished on same production line.
As shown in Figure 4, be the stereogram of input pin 1 of the present invention or 2, constitute with brace 2-2 (structure is identical) with brace 1-2 or pin 2-1 by pin 1-1; The upper end of pin 1-1 is two bifurcateds---resistor cartridge 1-1-1 and down-lead bracket 1-1-2, but the recess setting-in resistance 13 of resistor cartridge 1-1-1 upper end, down-lead bracket 1-1-2 upper end bending, the perpendicular end that is the brace 1-2 of T font is riveted joint sheet 1-2-1, horizontal end is bonding pad 1-2-2, riveted joint sheet 1-2-1 and the bending riveted joint of down-lead bracket 1-1-2 upper end, bonding pad 1-2-2 can weld the lead-out wire of coil 15.
As Fig. 4 in conjunction with shown in Figure 2, input pin 1 is identical with 2 structures, its brace 1-2 is positioned at the side of coil 15, assembly space is bigger, setting-in resistance 13 on the resistor cartridge 1-1-1 and on bonding pad 1-2-2 the lead-out wire of molten bonding wire circle 15 very convenient, and after coil 15 Chan systems are finished, just can carry out molten weldering at once, avoided the trouble of inter process in semi-finished product transportation that brings too much and production management between Chan system and the molten weldering.Thereby the problems that existing miniature normally open relay for automobile exists have been solved.
