Abstract
The utility model relates to a single-phase direct current contactor with a control interface. The single-phase direct current contactor with the control interface comprises a magnetic circuit portion, a reed assembly portion, a foundation portion, a mounting rack portion, a push rod portion, contacts, an armature, a cover casing, insulation sleeves, a main pressure spring, an auxiliary pressure spring, lining, a sealing ring and a gasket and is characterized in that the mounting rack portion (2) is mounted on the magnetic circuit portion (1), the sealing ring (3), the reed assembly portion (4) and the cover casing (5) are mounted on the mounting rack portion (2) in order, the push rod portion (6), the main pressure spring (7) and the armature (8) penetrate through a center of the mounting rack portion (2), the foundation portion (9), the insulation sleeve A (10), the contacts (11), the insulation sleeve B (12), the auxiliary pressure spring (13), the gasket (14), the cover casing (15) and a connector (16) are mounted under the magnetic circuit portion (1) in order. According to the single-phase direct current contactor with the control interface, an auxiliary contact wiring terminals and a coil leading out terminal are integrated on the circuit board and are led out through the connector to make the volume and the weight of product be greatly reduced; leading out terminals of a pair of long arms guarantee heat radiation of the contacts to make temperature rising of the contacts be in relatively stable values.
Description
Technical field
The utility model relates to the single-phase DC contactor, particularly is with control interface single-phase DC contactor.
Background technology:Existing single-phase DC contactor, auxiliary contact mostly use lead-out wire directly to receive exit, in the situation that the less use of auxiliary contact is comparatively convenient.More when auxiliary contact, if auxiliary contact exist dynamic circuit connector and quiet closing when conversion, wiring increases thereupon, product use and process of the test in lead-out wire have crossover phenomenon, to product use and test has brought inconvenience.Simultaneously, existing contactor load is larger, and the exit of auxiliary contact all is the mode of connection of bolt, nut, when auxiliary contact were more, the volume and weight of whole product will increase, therefore, in the process of using, can occupy larger space, simultaneously also so that weight of equipment can increase weight.
Summary of the invention:The purpose of this utility model is to solve weak point of the prior art, provides that a kind of volume is little, lightweight, the band control interface single-phase DC contactor of the large Belt connector of load.In order to realize this target, when product design, consider the layout that changes exit in the past and be connected lead-out mode, should alleviate as much as possible simultaneously the weight of product, and the correlation properties of reference circuit board and connector, with the mechanical connection on the existing contactor of connection realization of circuit board, so just can in less spatial dimension, realize identical functional characteristic.The utility model contactor is integrated into auxiliary contact terminals and coil exit on the circuit board, draw by connector, tentatively realized the integrated and standardization of contactor auxiliary contact exits, so that the volume and weight of product reduces greatly, and contact portion and exit adopt integrated design, a pair of long-armed exit has guaranteed the heat sinking function of contact, so that the contact temperature rise remains on metastable numerical value.
Formation of the present utility model: formed by magnetic circuit part, spring assembly part, base part, installing rack part, pusher section, contact, armature, case, insulating case, main stage clip, auxiliary stage clip, lining, sealing ring, packing ring, on magnetic circuit part, load onto the installing rack part, on installing rack part, pack into successively sealing ring, spring assembly part and case, middle run through pack into successively below the magnetic circuit part base part, insulating case A, contact, insulating case B, auxiliary stage clip, packing ring, case and connector by pusher section, main stage clip, armature.
Compared with the prior art, the utlity model has following characteristics:
1. changed contactor auxiliary contact exit and be connected the mode that connects with bolt, nut with the coil exit, existing exit with auxiliary contact and coil is integrated into the attachment unit interface terminal by circuit board, draws from connector port in the lump.Because the mode that adopts connector to replace bolt, nut to connect is so that the volume and weight of product significantly descends.
2. pedestal cooperates with the monnolithic case of product, greatly reduce on the pedestal overall dimension in design, in order to reduce the static contact spring piece heat dissipation problem that reduces to bring because of base size, static contact spring piece is designed to long-armed type, long exit so that the heat dissipation problem during product work be resolved.
3. wiring is more convenient.
Description of drawings:Fig. 1 is the utility model structural representation.
Fig. 2 auxiliary contact distribute and the interface schematic diagram.
Fig. 3 product circuit schematic diagram.
Among the figure: 1. magnetic circuit part, 2. installing rack part, 3. sealing ring, 4. spring assembly part, 5. case, 6.S pusher section, 7. main stage clip, 8. armature, 9. base part, 10. insulating case, 11. contacts, 12. insulating case B, 13. auxiliary stage clips, 14. packing rings, 15. cases, 16. connectors.
Embodiment:As shown in Figure 1 and Figure 2, on magnetic circuit part 1, load onto installing rack part 2, on installing rack part 2, pack into successively sealing ring 3, spring assembly part 4 and case 5, middle run through by pusher section 6, main stage clip 7, armature 8, pack into successively below the magnetic circuit part 1 base part 9, insulating case A10, contact 11, insulating case B12, auxiliary stage clip 13, packing ring 14 and case 15 and base part are with rivet riveting jail.Connector 16 is welded on the spring assembly part 4.
During product work, when A1 and A2 added specified excitation in circuit theory Fig. 3, movable contact spring part C1, C2, C3 disconnected with normally-closed contact R1, R2, R3 respectively, and contact with normally opened contact T1, T2, T3 simultaneously, the main contacts adhesive, and product work is at operate condition.When winding wiring de-energisation movable contact spring part disconnects with normally opened contact respectively, recover and the normally-closed contact contact condition, meanwhile main contacts disconnects, and product is finished once and is switched.
The execution mode of this patent is not limited to above-described embodiment, and the various variations of making under the prerequisite that does not break away from aim of the present invention all belong within protection scope of the present invention.
