Abstract
The utility model relates to a steady rest, in particular to a steady rest used for fixing etched circuit cards in a box body of electronic equipment, wherein a track groove of the steady rest is provided with an elastic cramping apparatus whose elasticity points to the surface of a clamped object in the track groove. According to the technical scheme, the utility model is provided with the elastic cramping apparatus on the steady rest, which enables the track groove to be applicable to etched circuit cards with a plurality of thickness specifications, and injection molding of ABS plastic is applied to replace prior machine shaping of aluminum alloy on material and processing method, which makes the process simpler, and saves manufacturing cost.
Description
Technical field
The utility model relates to a kind of fixed support, relates to a kind of fixed support that is used for electronic equipment casing internal fixation printed circuit board (PCB) specifically.
Background technology
The fixed support that is used for electronic equipment casing fixed printed circuit boards such as cabinet, switch cubicle in the prior art is material usually with the aluminium alloy, guide-track groove on the fixed mount generally adopts the technical method of machine work moulding to realize, this method not only technology is loaded down with trivial details, and the size of guide-track groove and shape are all unadjustable, this just causes when running into the printed circuit board (PCB) of different-thickness, need process fixed support, increase production cost virtually with different in width guide-track groove.
Summary of the invention
The purpose of this utility model provides a kind of fixed support of elastic clamp device, and its guide-track groove can be installed the printed circuit board (PCB) of multiple thickness specification, and clamping is reliable, and technology is simple, saves cost.
For achieving the above object, the utility model has adopted following technical scheme: the guide-track groove of support is provided with elastic clamp device, and the elastic force of this elastic clamp device is pointed to the surface of gripped object in the guide-track groove.
As shown from the above technical solution, the utility model is provided with elastic clamp device on the guide-track groove of support, makes guide-track groove go for the printed circuit board (PCB) of multiple thickness specification; On material and processing method, replace in the past aluminium alloy machine work moulding with the injection mo(u)lding of ABS plastic, make technology become simply, and saved production cost.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the enlarged drawing of A portion among Fig. 1;
Fig. 4, Fig. 5 are two kinds of execution modes in addition of the present utility model;
Fig. 6 is the enlarged drawing of B portion among Fig. 5.
Embodiment
As shown in Figure 1, support bracket fastened guide-track groove 10 is provided with elastic clamp device, and the elastic force of this elastic clamp device is pointed to the surface of gripped object in the guide-track groove.Because elastic clamp device has the elasticity degree of freedom, so can be used for assembling the printed circuit board (PCB) of multiple thickness specification.
The elastic clamp device that the utility model is selected for use is a flexure strip 20, flexure strip 20 is a strip of sheet, its cambered surface is positioned at guide-track groove 10, one side channel wall of guide-track groove 10 is a discontinuous, its discontinuities is connected as one by flexure strip 20 smooth transition, and flexure strip 20 leaves certain clearance with the bottom land junction of guide-track groove 10, and flexure strip 20 is to adopt the technology of once injection moulding to be connected as a single entity with the cell wall of guide-track groove 10.Cell wall adopts the structure of discontinuous both to solve the problem of resilient clamp, has reduced the materials of cell wall again effectively, and elastic clamp device contacts by face with the surface of gripped object and become a contact, on the mechanics angle science more.
As shown in Figure 3, the place, arc top of flexure strip 20 is the minimum thickness value of printed circuit board (PCB) apart from the distance h 1 of another cell wall, distance h 2 between two cell walls is the maximum ga(u)ge value of printed circuit board (PCB), and just the thickness of the printed circuit board (PCB) that can assemble must be between h1 and h2.
The notch place of guide-track groove 10 is the horn-like targeting port that is provided with laterally, can make things convenient for the insertion of printed circuit board (PCB).
Elastic clamp device and cell wall be combined with multiple mode, the utility model selects the technology of disposable injection molded that one side channel wall of flexure strip 20 and guide-track groove 10 is connected as a single entity, as shown in Figure 4, flexure strip 20 can all be provided with on two side channel walls; Flexure strip 20 cell wall of also can getting along well is connected as a single entity, and as Fig. 5, shown in Figure 6, is provided with groove on cell wall, and flexure strip 20 is inserted wherein, can play same effect equally.No matter which kind of mode of selection is provided with elastic clamp device, elastic clamp device can evenly be provided with some along the flute length direction of guide-track groove 10.
As shown in Figure 2, be provided with reference column 30 and unidirectional detent 40 with the one side that the guide-track groove of support deviates from mutually.Reference column 30 and unidirectional detent 40 are used for fixing with electronic equipment casings such as cabinet, switch cubicles.
Material as Fig. 1-support shown in Figure 3 is an ABS plastic, adopts the processes of once injection moulding to form.With ABS plastic is main material, has saved the production cost of producer; Replace the technology of machine work moulding with the technology of injection mo(u)lding, simplified technical process, also saved the time.
