Description
Technical field
The utility model relates to electronic control device, specifically a kind of high power relay.
Background technology
Present high power relay is meant the relay that 10A is above, and its structure generally comprises base, bobbin, coil, coil lead pin, yoke, moving spring, moving spring lead-out tablet, shell; Described bobbin is embedded on the base, and described coil is wrapped on the bobbin, and described lead-out wires of coil links to each other with coil and runs through and passes base, and described yoke is fixed on base and the bobbin, and described moving spring lead-out tablet and yoke are fitted and fixed with moving spring.Described moving spring lead-out tablet links to each other with high-tension electricity, described coil lead pin links to each other with low tension, because yoke links to each other with moving spring lead-out tablet, low tension is caused interference meeting misoperation and dangerous for fear of high-tension electricity like this, must will lead to the yoke of high-tension electricity and the coil and the coil lead pin of logical low tension and separate.
During work, as long as add certain voltage at the coil two ends, will flow through certain electric current in the coil, thereby generation galvanomagnetic effect, armature will overcome the pulling force that returns movable contact spring under the effect of electromagnetic attracting force inhales to iron core, thereby drives the moving contact and fixed contact (normally opened contact) adhesive of armature.Behind coil blackout, the suction of electromagnetism also disappears thereupon, and armature will return original position at the reaction force of movable contact spring, make moving contact and original fixed contact (normally-closed contact) adhesive.
The high power relay of above prior art has the following disadvantages:
1, owing to only separate by the certain space distance between coil and the yoke, like this in order to guarantee requirement of withstand voltage and safety standard, making between the two to have enough big space length, causes the bodily form of high power relay big.
2, because the last Plane Installation coil lead pin of base and two positions of moving spring lead-out tablet all are the plane, after bobbin is installed, gapped between bobbin and the base, like this in order to guarantee requirement of withstand voltage and safety standard, making between coil lead pin and yoke and coil lead pin and the moving spring lead-out tablet to have enough big space length, also causes the bodily form of high power relay big.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of and reaching the little high power relay of the bodily form under requirement of withstand voltage and the safety standard.
The technical solution of the utility model is, a kind of high power relay with following structure is provided, and comprises base, bobbin, coil, coil lead pin, yoke, moving spring, moving spring lead-out tablet, shell; Described bobbin, coil lead pin, yoke all are fixed on the base, and described bobbin is provided with the spacer that is used for retarder and yoke, first projection and second projection that are provided with isolation yoke and coil lead pin on the last plane of described base.
After adopting above structure, the utility model compared with prior art has the following advantages:
1, owing to sets up the spacer that is used for retarder and yoke at described bobbin upper edge axis direction, spacer can play good insulation effect, in order to guarantee requirement of withstand voltage and safety standard, can reduce space length between the two like this, the bodily form of high power relay is diminished.
2, because first projection and second projection of setting up isolation yoke and coil lead pin on the last plane of described base, first projection and second projection can play good insulation effect, after bobbin is installed, eliminated the gap between bobbin and the base plane, like this in order to guarantee requirement of withstand voltage and safety standard, can reduce the space length between coil lead pin and yoke and coil lead pin and the moving spring lead-out tablet, the bodily form of high power relay is diminished.
As improvement, the two sides of described spacer are equipped with guide rail along short transverse, and described bobbin is provided with and can spacer can be installed on the bobbin very easily, and plays good position-limiting action for two grooves of guide rail sliding fit.
As improvement, being used to of described bobbin bottom that an end of coil terminal pin is installed be provided with and first projection depression of embedding mutually, make the depression of first projection and bobbin chimeric, guarantee insulation effect.
As improvement, the bottom of described spacer is provided with the breach that matches with second projection, makes second projection and spacer get breach and matches, and guarantees insulation effect.
As improvement, the inner face of described shell is provided with the raised line that can offset with spacer, and after on the casing cover, raised line plays spacing effect up and down to spacer all the time.
