Hole, referring to Fig. 1.During assembling grafting, the first plug division 1-1 ' -1 be often fastened on above the first jack 2-1 of plastic plate 2 or
Person can not grafting in place, so as to cause Switch main body not fit to plastic plate, cause Switch main body hanging, terminal 1-1 ' and circuit
Loose contact between plate 3.Possibly it can not find that Switch main body does not fit to plastic plate and continues to be welded to circuit in time during operation
Plate, or microswitch is pressed again, it is likely that the damage of switch, plastic plate and circuit board is directly contributed, in turn results in supporting portion
Part is scrapped, and so not only causes waste and material loss, and will also result in environmental pollution.
The content of the invention
The purpose of the utility model is：There is provided it is a kind of it is simple in construction, prevent terminal is stuck can not the microswitch of grafting in place.
The technical solution of the utility model is：A kind of microswitch, including drain pan, it is upper lid, be arranged in drain pan and upper lid
Between micromotion mechanism and the triggering micromotion mechanism button, the micromotion mechanism includes being used for what is be connected with external circuit
Terminal, the terminal be followed successively by from inside to outside the first plug division that the first jack grafting with plastic plate coordinates and with circuit board
The second plug division that second jack grafting coordinates, first plug division both sides protrude from the second plug division and formed with shoulders,
Formed with oblique guide part between the shoulder of first plug division and the second plug division.
Preferably, the terminal includes the first terminal, Second terminal and the third terminal of parallel interval arrangement, and drain pan is in the
Be respectively formed with projection portion between one terminal and Second terminal, between Second terminal and third terminal, the protrusion of the projection portion away from
From the outreach that drain pan is stretched out less than the first plug division, during assembling grafting, projection portion is supported and is located on plastic plate, the first plug division
Outboard Sections and oblique guide part be located in the first jack of plastic plate, the second plug division is located in the second jack of circuit board
It is interior.
Preferably, the first plug division rectangular-blocklike structure, the end both sides of the second plug division have guiding surface.
The utility model has the advantages that：
1. inserted in the utility model between the shoulder of the first plug division of terminal and the second plug division formed with oblique guide part
When connecing assembling, oblique guide part can make the first plug division of terminal smoothly be caught in the first jack of plastic plate, avoid Switch main body not
Fit to plastic plate and be stuck on terminal the occurrence of, avoid connecing between Switch main body hanging, terminal and circuit board
Touch bad.
2. the protrusion distance of projection portion is less than the outreach that drain pan is stretched out in the first plug division in the utility model, assembling is inserted
When connecing, projection portion is supported and is located on plastic plate, is so served preferable position-limiting action, is avoided the situation of grafting tension.
