Further, left and right elastic arm is constituted by the bonding jumper of curved bending, the elastic deformation amount of the most left and right elastic arm is owing to the bending of bonding jumper brings, rigidity effect by bonding jumper, assisting block in rotation process is also played the effect of a rigid support by linking arm, so assisting block can also be more beneficial for the fast insert-pull of printed board by rigid support to one lever force of printed board effect in rotation process.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of electronic equipment cabinet in the present invention, is also the use state diagram of an embodiment of printed board power-assisted plug assembly in the present invention simultaneously.
Detailed description of the invention
The embodiment of electronic equipment cabinet is as shown in Figure 1: include casing, printed board 2 and backboard, casing includes the rail bar 4 that boxboard 3, lower boxboard and the multiple length being arranged on upper and lower boxboard inner surface extend along the longitudinal direction, two rail bars being oppositely arranged the most up and down are constituted a pair, it is provided with the guide rail that guide direction extends along the longitudinal direction on the opposite side of every pair of rail bar, printed board is provided with and is assemblied in the rail groove on corresponding guide rail for guiding movement from front to back.Two printed board power-assisted plug assemblies it are equipped with between casing and each printed board, two printed board power-assisted plug assemblies are oppositely arranged up and down, each printed board power-assisted plug assembly includes rotating the spring 5 being arranged at rail bar front end and rotating the assisting block 6 being 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 includes left elastic arm 52 and right elastic arm 51, left, right elastic arm is constituted by the bonding jumper of curved bending, bent by the arc of bonding jumper and make a left side, right elastic arm has elastic deformation amount on the pivot center direction be perpendicular to spring, left, connect between right elastic arm and have linking arm 53, left, right elastic arm constitutes U-shaped structure with linking arm.Assisting block is provided with the draw-in groove snapped in for linking arm, draw-in groove includes 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 more than a left side, the free state length of right elastic arm, assisting block is had in rotation process makes draw-in groove drive a left side, right elastic arm draws the first power-assisted position of stretcher strain and makes draw-in groove drive a left side, 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 operator between lozenges and the front end face of printed board, one section be connected with lozenges is plane, after printed board is completely inserted in backboard, and this plane and printed board front end face plane contact.
nullIn use，Each printed board guiding from front to back is assemblied in corresponding guide rail，When printed board is moved to corresponding guide rail end，Affected by plug connector between printed board and backboard，Printed board is suffered that moving resistance is gradually increased，Now linking arm is snapped in the draw-in groove in assisting block，Owing to 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 during rotating assisting block，Draw-in groove makes a left side、Right elastic arm stretcher strain，So left、Right elastic arm can give one pulling force backwards of assisting block，The most left、Right elastic arm can also play the effect of a balance pivot，So can more easily printed board be inserted on backboard by leverage and elastic force，Simultaneously under the effect of spring tension，Assisting block can be with firm locking not by external force time，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 operator, rotate backward assisting block, owing to the minimum range of the pivot center distance draw-in groove of spring is less than the free state length of left and right elastic arm, therefore in rotating assisting block, draw-in groove can make left and right elastic arm compression, the most left and right elastic arm can give a thrust forward, the most left and right elastic arm can also play the effect of a balance pivot, so can printed board be disassembled by backboard more easily by leverage and elastic force.Printed board power-assisted plug modular construction in the present invention is simple, operation is reliable and can realize the reliable fastening of printed board and fast quick-detach.
In the other embodiments of this electronic equipment cabinet: the number of printed board can also suitably select as required, such as one, two or other number；Rail bar can not also set, such as is directly arranged on boxboard by guide rail, and now spring can also directly rotate and be arranged on boxboard；Each printed board can also 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, assisting block is without being arranged on the front end face of printed board, such as printed board is arranged on the plate face of printed board；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 can also have helical spring to constitute；The pivot center of spring may be located on 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 when by dismounting on backboard, 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 plugs assembly with the printed board power-assisted described in above-mentioned each electronic equipment cabinet embodiment, is not described in detail in this.
