In sum, how fixed printed circuit board, to avoid control box size to the restriction of fixed printed circuit board, is current those skilled in the art's problem demanding prompt solution.
Utility model content
The purpose of this utility model is to provide a kind of control box being convenient to fitting printed circuit board, this control box can carry out installation to printed circuit board (PCB) easily to be fixed, firm position, without the need to using other instrument, avoids control box size to the restriction of fixed printed circuit board.
The utility model solves the technical scheme that its technical problem adopts:
A kind of control box being convenient to fitting printed circuit board, comprise the upper shell and lower house that removably connect, slot and gathering sill is provided with in described lower house, described slot is arranged on diapire in lower house, the top of slot is located at by gathering sill, the bottom of gathering sill is connected with described slot, and the top of gathering sill flushes with the overhead height of lower house, and the width of rebate of described gathering sill is greater than the width of rebate of slot; Described slot is formed with a side of printed circuit board (PCB) and coordinates, and makes printed circuit board (PCB) vertically be located in slot and gathering sill; Be provided with reference column in described upper shell, upper shell inner roof wall is fixed in one end of reference column, and the other end extends in the gathering sill of described lower house, and abuts with the top margin of described printed circuit board (PCB).
Further, described reference column mates with gathering sill and is connected, and the bottom of described gathering sill is converging transition from top to bottom.
Further, the gap in described gathering sill and printed circuit board face is 0.2mm, and the gap in described slot and printed circuit board face is 0.05mm, and the degree of depth of described slot is 4 ~ 6mm.
The beneficial effects of the utility model are, forming the slot coordinated, making printed circuit board (PCB) be vertically fixedly installed in control box, changing the mounting means of conventional flat by arranging in lower house with printed circuit board (PCB) side; By coordinating of reference column and gathering sill, printed circuit board (PCB) firmly being fixed in all directions, without the need to using other instrument during installation, avoiding control box size to the restriction of fixed printed circuit board, also saving the inner space of control box simultaneously, creating advantage for installing other electric component.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is exploded perspective view of the present utility model;
Fig. 2 is broken section enlarged diagram of the present utility model.
Embodiment
