Description
Technical field
The present invention relates to electronic circuit apparatus and manufacture field, specifically a kind of control box being convenient to fitting printed circuit board.
Background technology
Along with the development of science and technology, printed circuit board (PCB) (PrintedCircuitBoard is abbreviated as PCB) is by extensive extensive use.During use, generally printed circuit board (PCB) being installed in control box, in order to ensure the stability of printed circuit board (PCB), needing the degree of freedom of restriction printed circuit board (PCB) in control box, to avoid because its performance of wobble effects.At present, printed circuit board (PCB) is fixed on the housing of control box by usual employing screw, and screw needs to use instrument when fastening, such as screwdriver or torque spanner, so just need to be reserved with enough large operating space in the inner chamber of control box, if reserved operating space is less, then cannot completes fixing, cause the restriction being fixedly controlled box size of printed circuit board (PCB).In addition, the usual level of printed circuit board (PCB) is arranged on the bottom surface of control box inner chamber, and this also causes the operating space needed for fitting printed circuit board larger.
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.
Summary of the invention
The object of the present invention 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, and firm position, without the need to using other instrument, avoids control box size to the restriction of fixed printed circuit board.
The technical solution adopted for the present invention to solve the technical problems is:
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 invention has the beneficial effects as follows, forming with printed circuit board (PCB) side the slot coordinated by arranging in lower house, making printed circuit board (PCB) be vertically fixedly installed in control box, changing the mounting means of conventional flat; 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 present invention is further described:
Fig. 1 is exploded perspective view of the present invention;
Fig. 2 is broken section enlarged diagram of the present invention.
Embodiment
Composition graphs 1 is with shown in Fig. 2, the invention provides a kind of control box being convenient to fitting printed circuit board, comprise the upper shell 3 and lower house 4 that removably connect, upper shell 3 and lower house 4 are respectively equipped with one group of corresponding screw 2 along lip limit, make upper shell 3 adopt bolt to be fixedly connected with lower house 4 by screw 2; Be provided with slot 41 and gathering sill 42 in lower house 4, described slot 41 is arranged on the interior diapire of lower house 4, and slot specifically can be made to arrange along the longitudinal direction of lower house, and the madial wall of close lower house; The top of slot 41 is located at by gathering sill 42, the direction of gathering sill 42 is consistent with the direction of slot 41, the bottom of gathering sill 42 is connected with described slot 41, and the top of gathering sill 42 flushes with the overhead height of lower house 4, and the width of rebate of described gathering sill 42 is greater than the width of rebate of slot 41; Described slot 41 is formed with a side of printed circuit board (PCB) 1 and coordinates, and make printed circuit board (PCB) 1 vertically be located at slot 41 with in gathering sill 42, after printed circuit board (PCB) 1 is vertically fixed, its top margin is a little less than the top of gathering sill 42; Be provided with reference column 31 in described upper shell 3, the inner roof wall of upper shell 3 is fixed in one end of reference column 31, and the other end extends in the gathering sill 42 of described lower house 4, and abuts with the top margin of described printed circuit board (PCB) 1; Reference column 31 is formed with gathering sill 42 and coordinates, and makes reference column 31 be connected in gathering sill 42, and the bottom of described gathering sill 42 is converging transition from top to bottom, in order to strengthen locating effect, can arrange plural reference column 31 along interval, gathering sill direction.As preferably, described gathering sill 42 is 0.2mm with the gap in printed circuit board (PCB) 1 plate face, and described slot 41 is 0.05mm with the gap in printed circuit board (PCB) 1 plate face, and the degree of depth of described slot 41 is 4 ~ 6mm.
