Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of electronic equipment cabinet in the present invention, is also the using state figure of an embodiment of printed board power-assisted plug assembly in the present invention simultaneously.
Embodiment
The embodiment of electronic equipment cabinet is as shown in Figure 1: comprise casing, printed board 2 and backboard, casing comprises boxboard 3, lower boxboard and is arranged at the rail bar 4 that the multiple length on upper and lower boxboard inner surface extend along the longitudinal direction, two rail bars be wherein oppositely arranged up and down are formed a pair, the opposite side of often pair of rail bar is provided with the guide rail that guide direction extends along the longitudinal direction, printed board is provided with and is assemblied in the rail groove on corresponding guide rail for guiding movement from front to back.Be equipped with two printed board power-assisteds between casing and each printed board and plug assembly, two printed board power-assisted plug assemblies are oppositely arranged up and down, each printed board power-assisted plug assembly comprises rotation and is arranged at the spring 5 of rail bar front end and rotates the assisting block 6 be arranged on printed board front end face, the pivot center of spring is positioned at the rear side of the pivot center of assisting block, spring comprises left elastic arm 52 and right elastic arm 51, left, right elastic arm is formed by the bonding jumper of curved bending, a left side is made by the arc bending of bonding jumper, right elastic arm has elastic deformation amount perpendicular on the pivot center direction of spring, left, linking arm 53 is connected with between right elastic arm, left, right elastic arm and linking arm form U-shaped structure.Assisting block is provided with the draw-in groove snapped in for linking arm, draw-in groove comprises draw-in groove entrance 10 and draw-in groove positioning section 9, the groove depth bearing of trend of draw-in groove entrance is vertical with the groove depth bearing of trend of draw-in groove positioning section, the cell wall shape of draw-in groove positioning section and the shape adaptation of described linking arm, the maximum distance of the pivot center distance draw-in groove of spring is less than a left side, the free state length of right elastic arm, the minimum distance of the pivot center distance draw-in groove of spring is greater than a left side, the free state length of right elastic arm, assisting block is had in rotation process and makes draw-in groove drive a left side, right elastic arm draws the first power-assisted position of stretcher strain and draw-in groove is driven left, second power-assisted position of right elastic arm compression.A side surface opposing with described draw-in groove in assisting block is lozenges 8, have for the hand-held gap of operating personnel between lozenges and the front end face of printed board, one section that is connected with lozenges is plane, is inserted into completely after in backboard, this plane and printed board front end face plane contact in printed board.
In use, each printed board guiding is from front to back assemblied in corresponding guide rail, when printed board moves to corresponding guide rail end, by the impact of plug connector between printed board and backboard, printed board is suffered that moving resistance increases gradually, now linking arm is snapped in the draw-in groove in assisting block, because the ultimate range of the pivot center distance draw-in groove of spring is greater than a left side, the free state length of right elastic arm, therefore in the process of rotating assisting block, draw-in groove makes a left side, right elastic arm stretcher strain, such left side, right elastic arm can give assisting block one pulling force backwards, simultaneously left, right elastic arm can also play the effect of a balance pivot, can more easily printed board be inserted on backboard by leverage and elastic force like this, simultaneously under the effect of spring tension, assisting block is not by can firm locking during external force, ensure printed board and the firm grafting of backboard, when dismantling printed board, in the hand-held gap between assisting block and printed board of operating personnel, rotate backward assisting block, minimum range due to the pivot center distance draw-in groove of spring is less than the free state length of left and right elastic arm, therefore in rotation assisting block, draw-in groove can make left and right elastic arm compression, left and right like this elastic arm can give a thrust forward, left and right elastic arm can also play the effect of a balance pivot simultaneously, can printed board be disassembled by backboard more easily like this by leverage and elastic force.Printed board power-assisted plug modular construction in the present invention is simple, operation is reliable also can realize the reliably fastening of printed board and quick-detachment.
In other embodiment of this electronic equipment cabinet: the number of printed board can also suitably be selected as required, such as one, two or other number; Rail bar also can not be established, such as is directly arranged on boxboard by guide rail, and now spring also directly can rotate and be arranged on boxboard; Each printed board also can use a printed board power-assisted plug assembly, and this printed board power-assisted plug assembly is arranged at the middle part of printed board; When spring pivotal is arranged on boxboard, printed board without the need to being arranged on the front end face of printed board, such as is arranged on the plate face of printed board by assisting block; The groove depth bearing of trend of draw-in groove entrance can also be consistent with the groove depth bearing of trend of draw-in groove positioning section; Left and right elastic arm also can have helical spring to form; The pivot center of spring can also be positioned at the rear side of the pivot center of assisting block, and now printed board is when with backboard grafting, and spring provides a thrust forward for assisting block, and printed board is by when backboard is dismantled, and spring provides a pulling force backwards for assisting block.
Printed board power-assisted plugs the embodiment of assembly as shown in Figure 1: it is identical that the concrete structure of printed board power-assisted plug assembly and the printed board power-assisted described in above-mentioned each electronic equipment cabinet embodiment plug assembly, is not described in detail in this.
