Abstract
The utility model relates to a fixing device of circuit board for free space optical communication system, comprising a quadrate mother board which is used for fixing various devices. The two not adjacent edges of the mother board are provided with a symmetrical standing column. The one opposite side of the symmetrical column is provided with a sliding slot which can be inserted with a circuit board. The upper part of the column is provided with an ear sheet whose section presents a 'L' shape. The one face of the ear sheet can match with the upper part of the column in rotary state and in fixing state. The other face of the ear sheet is used for fixing the circuit board. Furthermore, a fixing blind hole can be arranged at the top of the column and the corresponding circuit board is fixed an ear sheet whose section presents a 'L' shape. The other face of the L'-shaped ear sheet is connected with the fixing hole of the column by screw bolts. The utility model has convenient, fastening and stable dismounting of the circuit board. Without the structure of designing cross beam, the space is saved for operating in narrow space.
Description
Technical field
The utility model relates to a kind of fixture of circuit board, relates in particular to a kind of free space optical communication (Free Space Optics, FSO) fixture of the circuit board of system of being used for.
Background technology
In electromechanics, communication product, the fixing means of existing circuit board has following main two kinds: the one, and level or vertically be fastened on the double-screw bolt by the key screw circuit board, this double-screw bolt is fixed in (as shown in Figure 1) on the motherboard, adopt the fastening circuit board of this method to reserve bigger operating space, with convenient handle screwdriver, the urgent screw of electric screwdriver of passing through at the end face of urgent screw; The another kind of structure that adopts subrack, plug-in card is promptly made a plug-in card case, needs each case face of design, perhaps design some crossbeams, wherein make some slideways and be used to plug circuit board (as shown in Figure 2), but adopt this method circuit board dense distribution, save certain space.But fastening circuit board need be used slideway, front end face design lower and upper cross-member in structural design, so many, the crossbeam of part and slideway take bigger space in structural design;
Disclose the patent No. in the Chinese patent literature and be 95211263.9 1 kinds and have box seat formula terminator terminating junctor, wherein relating to circuit board is card insert type, but does not describe its structure.
The utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, the fixture of the circuit board of being convenient to operate that is used for free-space optical communication system.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of fixture that is used for the circuit board of free-space optical communication system is provided, it comprises, fix the square motherboard that is roughly of various devices, be provided with the column of symmetry at two non-conterminous edges of this motherboard, the relative side of this symmetrical column is provided with the chute that can insert circuit board.
Further improvement in the technical proposal is: an auricle is set above column, and this auricle cross section is L-shaped, the top that it simultaneously turns and fixedly two states is matched with column, and another side is used for fixing circuit board.
The column cross section is square, in its outside one slope is arranged.
This chute top penetrates into the top of column, and the below ends in the bottom of column.
Another improvement project of the utility model is for being provided with a fixing hole at the top of column, corresponding circuit board is fixed an auricle, and this auricle cross section is L-shaped, should be connected with the fixing hole of column by bolt by " L " shape auricle another side.
The column cross section is square, in its outside one slope is arranged.
This chute top penetrates into the top of column, and the below ends in the bottom of column.
The beneficial effects of the utility model are: because this structure of employing of the present utility model, in use, the circuit board that needs are fixing inserts in the chute, fixing circuit board of " L " shape auricle, the top of another face vertical columns has promptly guaranteed the convenience, fastening, stable of dismounting circuit board, need not design structures such as crossbeam again, save the space so that operate at narrow space.
