Abstract
The invention discloses a rapid-plugging astrionics case. A PCB (Printed Circuit Board) with an electronic device is fixed inside a protective shell to constitute a single board module. Two plugging boosters are respectively fixed at the left side and the right side of the single board module, meanwhile, an upper plate and a lower plate of a case body are respectively provided with one groove at a proper position so as to coordinate with the plugging boosters to complete the plugging in/out process of the single board module. A front cover and the side wall of the case are connected together through a hinge pin, a non-falling nail is attached to the front cover, and the size of a hexagon socket head at the head part of the non-falling nail is identical to the size of the hexagon socket head of a elongated rod of a locking strip as an accessory of the single board module. The front cover and the other three side faces of the case body are mutually overlapped and engaged. The rapid-plugging astrionics case disclosed by the invention has the beneficial effects that under the condition of guaranteeing a better shielding effect, the replacement work of the single board module can be completed rapidly, the work strength is greatly reduced, and the reliability is high.
Description
Technical field: the present invention relates to a kind of electronics cabinet, 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.
Summary of the invention: be directed against the deficiency of above-mentioned prior art, but the invention provides a kind of astrionics cabinet of fast insert-pull.
For realizing above-mentioned purpose, the technical scheme that the present invention 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 work the process of pulling out.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 invention has the beneficial effects as follows that guaranteeing can to accomplish more changing jobs of veneer module fast under the situation of shield effectiveness preferably, reduced working strength greatly, reliability is high.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
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.
