Description
Technical field
The utility model relates to the mechano-electronic field, and a kind of double-contact relay is provided especially.
Background technology
Present relay is a single contact mostly, in actual application, causes single contact to damage easily, relay lost efficacy, and the utility model provides a kind of pair of electric shock relay, is mainly used in automobile industry, the application of two electric shocks has increased the contact area of contact, is original 2 times.The reliability and the fail safe of contact conducting have been guaranteed; Strengthened the magnitude of current of contact, significantly reduced electric current the impact of contact has been reduced infringement to the contact; 3～5 times of the useful lifes of prolongation product.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of double-contact relay is provided especially.
The utility model provides a kind of double-contact relay, it is characterized in that: include spring 1, coil 2, retort stand 3, iron core 4, plastic feet 5, adhesive sheet 6, shell fragment 7, moving contact 8, fixed contact 9, coil inserted sheet 10, coil inserted sheet 11, load inserted sheet 12, load inserted sheet 13; Its medi-spring 1 is connected with adhesive sheet 6, retort stand 3, iron core 4 passes coil 2 centre bores and is connected with retort stand 3, adhesive sheet 6 and shell fragment 7 riveted joints, moving contact 8 and shell fragment 7 riveted joints, fixed contact 9 is connected with load inserted sheet 12, load inserted sheet 13, and coil inserted sheet 10, coil inserted sheet 11 are connected with coil 2.
Described double-contact relay, moving contact 8 adopts the double-contact structure, and corresponding fixed contact 9 also is a double-contact.
Generated an electromagnetic field by electricity coil inserted sheet 10, coil inserted sheet 11 logical rated voltage coils, iron core produces suction to the adhesive sheet under the effect of electromagnetic field, adhesive sheet 6 drives shell fragment 7 motions, thereby moving contact 8 is contacted with fixed contact 9, load inserted sheet 12, load inserted sheet 13 paths have reached and have connected the purpose that the load power source loop makes the load operate as normal.
Advantage of the present utility model: having increased the contact area of contact, is original 2 times.The reliability and the fail safe of contact conducting have been guaranteed; Strengthened the magnitude of current of contact, significantly reduced electric current the impact of contact has been reduced infringement to the contact; 3～5 times of the useful lifes of prolongation product.
