Abstract
The utility model provides an aerospace electronics case capable of quick plugging/unplugging. A PCB provided with electronic components is fixed in a protecting shell, thereby forming a single-board module. Two plugging-resisting devices are fixed on the left side and the right side of the single-board module respectively. At the same time, a grooves is arranged in each of appropriate positions on an upper plate and a lower plate of a case body of the case, thereby cooperating with the plugging-resisting devices for realizing a process of unplugging and plugging the single-plate module. A front cover and a side wall of the case are connected through a hinge shaft. An anti-drop nail is adhered to the front cover. The size of an inner hexagonal head of the head of the anti-drop nail is the same with an inner hexagonal head of a long and thin rod of a locking strip of an accessory of the single-plate module. The front cover engages with the other three sides of the case in a bridging manner. The aerospace electronics case capable of quick plugging/unplugging in the utility model has beneficial effects of realizing a replacement of the single-plate module rapidly under a condition of guaranteeing a comparatively good shielding effect. In this way, the working strength is reduced substantially, and the reliability of the aerospace electronics case capable of quick plugging/unplugging is high.
Description
Technical field: the utility model relates to a kind of electronics cabinet, and particularly a kind of fast insert-pull astrionics cabinet belongs to aerospace field.
Background technology: at present, known astrionics cabinet mainly is made up of casing and veneer module two parts.Its veneer module is by screw being fixed on the casing tightly, and the connector active force of veneer module and motherboard is bigger, causes dismounting very inconvenient; And need some aids to cooperate dismounting, simultaneously, in order to realize electromagnetic shielding; Each veneer module overlaps interlock each other; Therefore, can not realize arbitrarily plugging the veneer module, this has just increased operating personnel's workload greatly.In addition, the components and parts of veneer module expose, and in the plug process, require operating personnel to want very careful.
The utility model content: to the deficiency of above-mentioned prior art, but the utility model provides a kind of astrionics cabinet of fast insert-pull.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is: fast insert-pull astrionics cabinet, the pcb board that will have electronic devices and components fastens in a protection housing, to form the veneer module.Fixing respectively two drawing-aid devices in the left and right sides of veneer module, simultaneously respectively on the upper plate of cabinet casing and lower plate suitable position open a groove, cooperate drawing-aid device completion veneer module to rise and pull out and insertion process.Protecgulum and cabinet sidewall are coupled together through hinge pin, and with non-dropping off nail, the hexagon socket head size of non-dropping off nail head is identical with the hexagon socket head model of the elongate rod of veneer module accessories locking strip on the protecgulum.Other three sides of protecgulum and casing overlap interlock each other.
The beneficial effect of the utility model is, guaranteeing can to accomplish more changing jobs of veneer module fast under the situation of shield effectiveness preferably, reduced working strength greatly, and reliability is high.

Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of protecgulum.
Fig. 3 is the structural representation of veneer module.
Fig. 4 is veneer module withdrawal process figure.
Embodiment:
As shown in Figure 1: fast insert-pull astrionics cabinet, the pcb board that will have electronic devices and components fastens in a protection housing, to form veneer module 7.Fixing respectively two drawing-aid devices 1 in the left and right sides of veneer module 7, simultaneously respectively on the upper plate 2 of cabinet casing and lower plate suitable position open a groove, cooperate drawing-aid device 1 to accomplish 7 of veneer modules and pull out and insertion process.But, therefore, can cause the effectiveness meeting of whole cabinet very poor owing to be separate between each veneer module of this moment.In order to address this problem, protecgulum 4 bulk shieldings have been adopted.Mainly be that protecgulum 4 and cabinet sidewall are coupled together through hinge pin; Have 14 hexagon socket head non-dropping off nail 5 on the protecgulum 4; The hexagon socket head model of the annex locking strip elongate rod 6 on the hexagon socket head size that has particularly guaranteed these non-dropping off nail 5 heads and the veneer module 7 is identical, can guarantee that like this operator only need use an instrument just can accomplish the dismantlement work of veneer module 7 easily and fast.Protecgulum 4 overlaps interlock each other with other three sides of casing, guarantees the applying of protecgulum 4 and casing through 14 hexagon socket head non-dropping off nail, to reach shield effectiveness preferably.Drawing-aid device 1 according to lever principle, is given casing upper plate 2 groove lower surfaces with force transmission, thereby is overcome the active force of veneer module bottom connector, and then veneer module 7 is extracted under external force.Otherwise, when veneer module 7 is inserted cabinet, give casing upper plate 2 groove upper surfaces, thereby overcome the active force of veneer module 7 bottom connectors, and then veneer module 7 is inserted force transmission.Protecgulum 4 is realized shielding with cabinet right plate 3 through vertical overlap joint.
In Fig. 2 and Fig. 3, the head model of non-dropping off nail 5 and locking strip elongate rod 6 is measure-alike.
In instance shown in Figure 4, can see the overall process that the veneer module is extracted from cabinet.
Claims (1)
1. fast insert-pull astrionics cabinet; The pcb board that will have electronic devices and components fastens in a protection housing; To form the veneer module, it is characterized in that: fixing respectively two drawing-aid devices in the left and right sides of veneer module have the groove that cooperates with drawing-aid device on the upper plate of cabinet casing and lower plate; Protecgulum is connected through hinge pin with the cabinet sidewall; With non-dropping off nail, the hexagon socket head size of non-dropping off nail head is identical with the hexagon socket head model of the elongate rod of veneer module accessories locking strip on the protecgulum, and other three sides of protecgulum and casing overlap interlock each other.
