Line between the center of circle in position hole and the center three of two jacks is triangle, and the connection between travel switch and battery case is steady
It is qualitative more preferable.
As an improvement, the other end in the ontology is additionally provided with two connecting columns, the connecting column is located at described
The two sides of connection sheet, connecting column for grafting into the circular hole on pcb board so that travel switch is fixed together with pcb board.
As an improvement, the connection sheet and the connecting column be not in same along the width direction of the ontology
On straight line, connecting column and connection sheet are dislocatedly distributed, and are convenient for subsequent welded connecting piece and pcb board.
As an improvement, the lower end of the connecting column is taper, it is convenient for grafting.
As an improvement, the lower end of the connecting column, which is equipped with, is divided into two-part elongated slot for connecting column, elongated slot can be provided
Certain cushion space can directly be less than connecting column, at this time due to there is elongated slot to deposit in the circular hole being arranged on pcb board
, connecting column lower end also can grafting into circular hole, in the grafting of connecting column lower end into after in circular hole, connecting column restores deformation so that
Its connective stability between circular hole is more preferable.
As an improvement, the width of one end of the ontology is not more than the width of its other end, travel switch is avoided therefrom
Portion fractures, and increases its integral strength.
