Description
Technical field
The utility model relates to a kind of electromagnetic relay, the electromagnetic relay that particularly a kind of pushing block is easy for installation.
Background technology
At present, on China national intellectual property board web, the utility model patent that Authorization Notice No. is " CN 2383205Y " discloses one " low clearance small high-power electromagnetic relay ", it comprises housing, base, pushing block, contact portion and magnetic circuit part, base is provided with a cavity, magnetic circuit part is arranged on base side and is contained by cavity, contact portion is arranged on base opposite side, contact portion includes movable contact spring, pushing block is enclosed within chamber outer wall upper end, pushing block one end is connected with magnetic circuit part, the pushing block other end is adjacent with movable contact spring, pushing block is provided with backstay in the middle part of one end adjacent with movable contact spring, the circular hole passed for backstay is provided with in the middle part of movable contact spring.There is a weak point in this electromagnetic relay: due to when installing pushing block in actual application, need first pushing block one end to be connected with magnetic circuit part, then movable contact spring is pushed aside to away from pushing block direction, again backstay is inserted in the circular hole of movable contact spring, finally pushing block is enclosed within chamber outer wall upper end, therefore the installation of pushing block not only comparatively bothers, if the strength that assembly crewman stirs movable contact spring in installation pushing block process uses excessive, can not restPose with regard to likely causing movable contact spring excessive deformation, thus cause movable contact spring damage to be scrapped.
Utility model content
The technical problems to be solved in the utility model is, not only pushing block is easy for installation to provide one, and when installing pushing block, can effectively avoid movable contact spring to damage the electromagnetic relay scrapped.
For solving the problems of the technologies described above, the utility model provides a kind of electromagnetic relay adopting the pushing block of following structure easy for installation: it comprises housing, base, pushing block, contact portion and magnetic circuit part, base right part is provided with an open-ended cavity to the right, magnetic circuit part is arranged on base right part, and magnetic circuit part left part is arranged in cavity, contact portion is arranged on base left part, contact portion includes movable contact spring, pushing block right-hand member is connected with magnetic circuit part, pushing block left end is adjacent with movable contact spring, housing lower end is connected with base, wherein, pushing block is positioned at above chamber outer wall, stopper slot is provided with in the middle part of pushing block, chamber outer wall upper end is provided with the guide vane end stop that can horizontally slip in stopper slot, housing cavity top is provided with a pair positive stop strip, two positive stop strips to be positioned at above pushing block and to lay respectively at the both sides, front and back of stopper slot, pushing block lower end is provided with pair of sliding bar, two slider bars are pressed in chamber outer wall upper end and lay respectively at both sides before and after stopper slot.
After adopting said structure, the utility model has the following advantages: when installing pushing block, only need first pushing block right-hand member to be connected with magnetic circuit part, then pushing block is placed on housing cavity outer wall upper end, and make the guide vane end stop being located at interior cavity outer wall upper end be arranged in stopper slot in the middle part of pushing block, finally cover housing, the location to pushing block can be realized, under the stop of a pair positive stop strip being located at housing cavity top, pushing block to move up and down space very little, even if electromagnetic relay easy for installation for the utility model pushing block be upside down placement, guide vane end stop also can not from stopper slot out.As from the foregoing, pushing block in the electromagnetic relay that the utility model pushing block is easy for installation is not only easy for installation, and, pushing block is without the need to positioning by movable contact spring again, therefore when installing pushing block, assembly crewman need not go to stir movable contact spring again, thus effectively prevent movable contact spring and damage the situation of scrapping and occur.
