The advantage that the utility model has and beneficial effect are:
1, the utility model compact conformation, forms elasticity draw-in groove between the first double wedge and between the second double wedge, and circuit board corner is positioned between double wedge, can play antihunt action and reinforcement effect;
2, the first double wedge on protective cover and the second double wedge also can strengthen the bulk strength of protective cover, guarantee that circuit board protective cover under heat condition deformation can not occur.
Projection is extended in the side being provided with opening in the bottom surface of 3, protective cover, makes between protective cover and connecting plate, to leave a fixed gap, upset convenient for assembly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of another angle of the present utility model.
In figure: 1. protective cover, 2. connecting plate, 3. projection, 4. the first double wedge, 5. the second double wedge.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As Fig. 1; shown in Fig. 2; the utility model provides a kind of circuit board anti-vibration protected cover; comprise connecting plate 2, be positioned at the protective cover 1 of described connecting plate 2 bilateral symmetry setting; described protective cover 1 and the one-body molded setting of described connecting plate 2; described connecting plate 2 is used for connecting and fixing protective cover 1; described protective cover 1 is the shell construction of inner hollow; the top of described protective cover 1 is opening-like; its side near described connecting plate 2 is opening-like; the bottom of described protective cover 1 is provided with multiple first double wedge 4, and the madial wall of described protective cover 1 is provided with multiple second double wedge 5.Circuit board corner is positioned between double wedge, can play antihunt action and reinforcement effect, and meanwhile, the setting of multiple first double wedge 4 and the second double wedge 5 also can strengthen the bulk strength of protective cover 1, guarantees that circuit board protective cover 1 under heat condition deformation can not occur.
Wherein, described first double wedge 4 is arranged along the direction of described protective cover 1 central shaft, and the edge near described connecting plate 2 one end described protective cover 1 bottom interior wall extends on the rear wall of described protective cover 1; Described second double wedge 5, along the U-shaped setting of described protective cover 1 gusset inwall, extends to the sidewall edge place near the other end of described connecting plate 2 on described protective cover 1 near the end side mural margin of described connecting plate 2 from protective cover 1.First double wedge 4 and the second projection 5 play the effect of collaborative fixing circuit board, enhance the steadiness of circuit board.
Further, in without pitch arrays arrangement between described first double wedge 4, in without pitch arrays arrangement between described second double wedge 5, make between the second double wedge 5, to form elasticity draw-in groove between the first double wedge 4, be convenient to circuit-board card to be positioned at elasticity draw-in groove.
