Abstract
The utility model discloses a misinsertion-prevention structure of a circuit board carrying box. The structure is characterized in that one side of the circuit board carrying box is provided with a protruding rib facing the inner side of the carrying box; a clamping groove is arranged on a corresponding side of a circuit board; and the circuit board carrying box and the circuit board in assembly are located in such a way that the protruding rib is inserted in the clamping groove. The misinsertion-prevention structure has the advantages of simple structure and good locating effect and is capable of effectively guaranteeing the accurate installation of the circuit board in the circuit board carrying box and improving the working efficiency.
Description
Technical field
The utility model relates to a kind of circuit board holder box mounting structure.
Background technology
Circuit board holder box of the prior art is directly to install with circuit board, and because of the obvious identification mark of nothing, often easy anti-loaded direction, affect production efficiency.
The utility model content
The utility model is for avoiding the existing weak point of above-mentioned existing structure, and a kind of circuit board holder box Anti-misplug structure is provided, to guarantee the accurate installation of circuit board on circuit board holder box.
The utility model adopts following technical scheme for dealing with problems:
A kind of circuit board holder box Anti-misplug structure, be characterized in, at a side of circuit board holder box, one convex tendon towards holder box inboard is set, be provided with draw-in groove on a corresponding side on circuit board, the circuit board holder box in assembling and circuit board are to be inserted in described draw-in groove and to realize location with described convex tendon.
Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model is simple in structure, good positioning effect, can effectively guarantee the accurate installation of circuit board in circuit board holder box, increases work efficiency.
The accompanying drawing explanation
Fig. 1 is circuit board holder box structural representation in the utility model;
Fig. 2 is board structure of circuit schematic diagram in the utility model;
Number in the figure: 1 circuit board holder box, 2 convex tendons, 3 circuit boards, 4 draw-in grooves.
Embodiment
Referring to Fig. 1 and Fig. 2, in the present embodiment, circuit board holder box Anti-misplug structure is that a side at circuit board holder box 1 arranges a convex tendon 2 towards holder box inboard, be provided with draw-in groove 4 on a corresponding side on circuit board 3, the circuit board holder box 1 in assembling is to be inserted in draw-in groove 4 and to realize location with convex tendon 2 with circuit board 3.
In assembling, only have when draw-in groove 4 is aimed to convex tendon 2, just can complete assembling; When reverse installation, due to draw-in groove 4 and convex tendon 2 mutually socket joint coordinate, can't realize assembling, realized the purpose of circuit board Anti-misplug in circuit board holder box.
