Abstract
The utility model discloses a kind of three groups of bridging contact level conversion structures.Comprise pushing block (1) and movable contact spring (3), described pushing block (1) is provided with six square through holes (9), and described movable contact spring (3) is connected with pushing block (1) through square through hole (9), and movable contact spring (3) is provided with contact (4).The utility model has and fast outside two three-phase circuits is carried out level conversion and the good beneficial effect of contact.
Description
Technical field
The utility model relates to a kind of contact level conversion structure, particularly a kind of three groups of bridging contact level conversion structures.
Background technology
Three-phase contactor is the base components on low-voltage control line, and its scope of application is wide, consumption is large, kind is many, is a kind of more satisfactory three-phase circuit control apparatus.At present, the three-phase contactor of most of contacts horizontal movement structures design on the market only possess control single circuit cut-off function, and do not possess the function of two three-phase circuits being carried out conversion and control.In engineer applied, need the application by two three-phase circuits carry out conversion and control to get more and more, the three-phase contactor of traditional contact horizontal movement structures conveniently cannot realize the conversion and control of outside two three-phase circuits.
Summary of the invention
The purpose of this utility model is, provides a kind of three groups of bridging contact level conversion structures.This utility model possesses the function of outside two three-phase circuits being carried out fast level conversion, and contact is good.
The technical solution of the utility model: a kind of three groups of bridging contact level conversion structures, comprise pushing block and movable contact spring, described pushing block is provided with six square through holes, and described movable contact spring is connected with pushing block through square through hole, and movable contact spring is provided with contact.
Aforesaid three groups of bridging contact level conversion structures, often organize between described square through hole and be provided with a circular groove, described movable contact spring is provided with guide pin bushing, and guide pin bushing is placed in circular groove, often organizes between guide pin bushing and is provided with stage clip.
The beneficial effects of the utility model: compared with prior art, the utility model by installing three groups of movable contact springs on pushing block, and when operating pushing block, three groups of movable contact springs move simultaneously, realizes the level conversion function of outside two three-phase circuits.Be provided with stage clip between the guide pin bushing simultaneously often organizing movable contact spring, when contact contacts with normally-closed contact or normally opened contact, stage clip can provide thrust, guarantees that contact is good.In sum, the utility model has the function of outside two three-phase circuits being carried out fast level conversion, and the beneficial effect that contact is good.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is movable contact spring structural representation;
Accompanying drawing 3 is the partial sectional view of pushing block;
Accompanying drawing 4 is utility model works schematic diagram;
Be labeled as in accompanying drawing: 1-pushing block, 2-stage clip, 3-movable contact spring, 4-contact, 5-guide pin bushing, 6-normally-closed contact, 7-normally opened contact, 8-circular groove, 9-square through hole.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment of the present utility model: as Figure 1-4, a kind of three groups of bridging contact level conversion structures, comprise pushing block 1 and movable contact spring 3, pushing block 1 have six square through holes 9, movable contact spring 3 is connected with pushing block 1 through square through hole 9, and movable contact spring 3 side is welded with contact 4.
Often organize between square through hole 9 and be provided with a circular groove 8, the centre of movable contact spring 3 opposite side is provided with guide pin bushing 5, and guide pin bushing 5 is placed in circular groove 8, often organizes between guide pin bushing 5 and is provided with stage clip 2.
The utility model is by arranging pushing block 1, and pushing block 1 arranges three groups of square through holes 9, often organizes two, totally six.Then movable contact spring 3 is set in square through hole 9, movable contact spring 3 side is provided with contact 4, side, contact 4 is provided with normally-closed contact 6 or normally opened contact 7, the side often organizing the place, contact 4 of movable contact spring 3 during assembling is placed dorsad, when not applying external force F, the contact 4 of B side contacts with normally-closed contact 6, be communicated with a three-phase circuit, when applying external force F, pushing block 1 moves to another direction, three groups of movable contact springs 3 and then move together, now contact, B side 4 is separated with normally-closed contact 6, contact, A side 4 contacts with normally opened contact 7, be communicated with another three-phase circuit simultaneously, achieve the level conversion of outside two three-phase circuits rapidly.
A circular groove 8 is provided with between square through hole 9, the centre of movable contact spring 3 opposite side is provided with guide pin bushing 5, during assembling, guide pin bushing 5 is placed in circular groove 8, often organize between guide pin bushing 5 and be provided with stage clip 2, in contact 4 with normally-closed contact 6 or normally opened contact 7 contact process, stage clip 2 provides thrust, ensures that contact 4 contacts well with normally-closed contact 6 or normally opened contact 7 in level conversion process.
