Abstract
The utility model discloses a relay, which comprises a coil, a poking sheet, a movable contact electrode, a fixed contact electrode, a movable contact electrode pulling block, a substrate and a clamping plate. The relay is characterized in that a lug boss is arranged on the movable contact electrode pulling block, and is positioned on a joint surface between the movable contact electrode pulling block and the movable contact electrode; and a through hole matched with the lug boss is formed on the movable contact electrode. Through the improved structure, the relay provided by the utility model overcomes the shortcomings of a traditional relay such as complicated structure and high cost due to the adoption of a connecting mode that a groove is formed at the edge of the movable contact electrode and a protruding part matched with the groove is arranged on the movable contact electrode pulling block, and also solves the problem that the movable contact electrode made of a metal sheet is easy to deform, so the movable contact electrode can not be forced evenly and the contact property of the movable and the fixed contact electrodes is influenced.
Description
Technical field
The utility model discloses relay, especially a kind of movable contact utmost point and the good relay of stationary contact utmost point contact performance belong to electricity field.
Background technology
Relay is one of electric component the most frequently used in people's daily life, and its structural behaviour and fail safe have significant impact to daily life.Relay primary structure in the market comprises coil, plectrum, the movable contact utmost point, the stationary contact utmost point, and movable contact utmost point pushing block, substrate, clamp, plectrum are fixed on the substrate and can rotate.Wherein the connected mode of the movable contact utmost point pushing block and the movable contact utmost point is for being provided with groove on the edge of the movable contact utmost point, the corresponding protuberance that is complementary with it that is provided with on the movable contact utmost point pushing block, mode by the convex-concave combination connects, thereby this connected mode complex structure, production cost height and use for a long time and as easy as rolling off a logly cause the movable contact utmost point distortion that sheet metal makes to cause movable contact utmost point discontinuity so that disturb the movable contact utmost point and the stationary contact utmost point contact performance safety problem occurs thereby may cause the isolation electricity bad temper of relay to descend for a long time.
Relay of the present utility model has overcome above-mentioned shortcoming.
Summary of the invention
The utility model discloses relay, overcome complex structure, cost height, the bad shortcoming of contact performance that the traditional relay movable contact utmost point pushing block and the movable contact utmost point adopt groove and tab to cause.
The disclosed relay of the utility model comprises coil, plectrum, the movable contact utmost point, the stationary contact utmost point, movable contact utmost point pushing block, substrate, clamp, be positioned on the movable contact utmost point pushing block its with face that the movable contact utmost point engages on be provided with boss, be provided with the through hole that is complementary with boss at movable contact on extremely.
Although the utility model does not limit the shape of boss, those skilled in the art can adopt suitable shape according to actual needs, preferably, boss described in the utility model is a step structure, the size at boss top is less than the size of boss base portion, the boss top is passed in the through hole that movable contact is extremely gone up, and the boss base portion promotes to touch the utmost point.
The relay movable contact utmost point of the present utility model is that boss combines with through hole with the combination of movable contact utmost point pushing block, have only stressed the comparing in movable contact utmost point marginal portion with traditional groove with tab, because combination all took place in all angles when boss combined with through hole, movable contact is extremely stressed more even, and the movable contact utmost point and stationary contact utmost point contact performance are better.
Further, compared with prior art, the relay movable contact utmost point of the present utility model combines with through hole with movable contact utmost point pushing block boss, and is simpler compared to traditional groove and tab structure, is easy to produce; Because its binding site is stressed evenly, long-term serviceability is more reliable, and fail safe is better.
Description of drawings
Accompanying drawing 2 is the utility model relay movable contact utmost point pushing block structural representation;
Embodiment
Accompanying drawing 2 is disclosed to be the structure of relay movable contact utmost point pushing block of the present utility model, on the movable contact utmost point pushing block 5 with face that the movable contact utmost point 3 engages on boss 8 is arranged.Those skilled in the art can determine the shape of boss 8 according to actual needs, and preferably, boss 8 is a step structure, and the size at its top 81 is less than the size of its base portion 82, and top 81 is passed in the through hole 9 on the movable contact utmost point 3, promote to touch the utmost point 3 with base portion 82.
Accompanying drawing 3 is the utility model relay movable contact electrode structure, and through hole 9 is arranged on the movable contact utmost point 3.
In accompanying drawing 2, the 3 disclosed movable contact utmost point pushing block structures of the present utility model, through hole 9 sizes in boss 8 and the movable contact electrode structure are complementary, and can combine closely.
