Produce efficient, production cost is low, applied widely.
In order to reach above-mentioned technique effect, the utility model takes following technical scheme：The printed board of adjustable width
Fixing device, it includes matrix and printed board, and described matrix one side or the multi-lateral is equipped with elastic construction, position limiting structure, interface arrangment；
The printed board is equipped with location hole；During assembling, in the position limiting structure insertion location hole, the opposite both sides clamping of the printed board
In the interface arrangment of matrix.By printed board and matrix be mutually fastenedly connected and position limiting structure, you can realization is fastenedly connected
It is reliable；By the elastic reaction of elastic construction, the different printed boards in the range of applicable one fixed width.
Further technical solution is：The interface arrangment is a pair of of card slot, is oppositely arranged on the both sides of matrix.
Further technical solution is：Installation gap, the interface arrangment are left between the position limiting structure and location hole
Inner wall and be connected between the side of printed board therein and leave installation gap.
Further technical solution is：Described matrix is equipped with fixed structure on the another side opposite with position limiting structure.
Further technical solution is：The one side or the multi-lateral of described matrix is equipped with auxiliary adjustment structure.
The utility model compared with prior art, has following beneficial effect：Pass through elastic construction and interface arrangment
Interaction, printed board 2 are reliably fastenedly connected with the mutually spacing formation of matrix 1, while by the elastic reaction of elastic construction, can
The different printed boards being applicable in the range of one fixed width, greatly improve the reliability of installation effectiveness and connection, decrease tight
Gu the quantity of part, improves versatility.
Present apparatus number of parts is few, and production cost is low, and assembly manipulation simple and fast, accurate positioning is reliable, applied widely.

Embodiment
The utility model is further elaborated with reference to the embodiment of the utility model.
Embodiment：
As shown in figs. 1-7, the printed board fixing device of adjustable width, it includes matrix 1 and printed board 2.Described matrix 1
One side or the multi-lateral is equipped with elastic construction 1a, position limiting structure 1b, interface arrangment 1e.The preferred interface arrangment 1e of the present embodiment blocks to be a pair of
Groove, is oppositely arranged on the both sides of matrix 1.The printed board 2 is equipped with location hole 2a；Before assembly, position limiting structure 1b and location hole
The position of 2a is corresponds, during assembling, in the position limiting structure 1b insertion location holes 2a, and the opposite both sides of the printed board 2
It is connected in the interface arrangment 1e of matrix 1, realizes that printed board fastens by the mutual spacing connection of position limiting structure and location hole
