The fixing device adopts the boss in the horizontal direction for space limiting, and is added with a step-shaped special-purpose pressure plate, and thus improves reliability in installation and use of the 1553B bus socket, and, while guaranteeing simple realization of design, simple processing and simple operation, guarantees high reliability of assembling, and effectively saves structural space dimension.
Description
Technical field
The utility model belongs to the Structural Design of Electronic System field, relates to a kind of 1553B bus hub fixture.
Background technology
The 1553B bus hub is extensively adopted on spaceborne, missile equipment as a kind of important connector.Because when the clamp nut that socket carries outer cable in debugging and using repeatedly plugs, can occur becoming flexible, cause the 1553B bus hub to occur inevitably rotating or retreating phenomenon, cause solder joint to snap, equipment can't work.Former method is the muscle at two vertical directions of 1553B bus hub installation frame inner surface design, limit the rotation of the hexagon flange that socket carries with muscle, because flange thickness is 2mm, muscle is difficult to cleaning and meets at right angles adding the man-hour root, and because the existence of mismachining tolerance, the hexagon flange of 1553B bus hub can not firmly be blocked.So this method can only be rotated in restriction 1553B bus hub partly, root does not have the function that prevents that socket from shrinking back.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of 1553B bus hub fixture is provided, this device adopts the horizontal direction boss spacing, and increased the step special pressing plate, improved the reliability that the 1553B bus hub is installed and used, when guaranteeing that design realizes that simple, processing is easy, simple to operate, guarantee the high reliability of assembling, and effectively saved the structure space size.
Above-mentioned purpose of the present utility model is achieved by following technical solution:
A kind of 1553B bus hub fixture comprises special pressing plate and the framework of 1553B bus hub is installed.
Described special pressing plate is step, comprises recessed portion and projection, and the edge that recessed portion is close to 1553B bus hub hexagon flange is fixed in the medial surface of framework; Relative with described recessed portion, described framework is provided with boss; The hexagon flange that holds only the 1553B bus hub between described boss and the described recessed portion.
The utility model advantage compared with prior art is:
(1) the utility model fixture changes the muscle of vertical direction the design of into horizontal direction boss, and designs independently pressing plate, reduces difficulty of processing and installation difficulty; And press plate position is adjustable, thereby can eliminate the mismachining tolerance of the error of socket own and constitutional detail.Can guarantee that pressing plate and socket closely cooperate, thoroughly solve shrinking back and Rotation in the 1553B bus hub use procedure, thereby improve the reliability that the 1553B bus hub is used;
(2) the utility model fixture is fixed on pressing plate on the framework by the screw of 3 M2.5, has reduced difficulty of processing and assembly difficulty;
(3) the utility model fixture compared with prior art, because platen design, reduced difficulty of processing, improved installation accuracy, guaranteed installation strength, when ensureing that product has good anufacturability, improved assembly technology ease for operation, and can in assembling process, eliminate the impact of mismachining tolerance, guaranteed stability, reliability in the 1553B bus hub use, and the increase that does not bring size and weight.
Description of drawings
Fig. 1 is the utility model 1553B bus hub fixture schematic diagram;
Fig. 2 is the utility model 1553B bus hub fixture framework interior views;
Fig. 3 is the utility model 1553B bus hub fixture profile.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1,1553B bus hub fixture described in the utility model comprises pressing plate 1 and installation frame 2.Installation frame 2 is used for the 1553B bus hub is installed, and in the inboard of the installation frame 2 that the 1553B bus hub is installed, is fixed in pressing plate 1 by 3 GB screw m2.5*8.
Pressing plate 1 is step, comprises recessed portion 11 and projection 12.Recessed portion 11 is affixed with a side of the hexagon flange of 1553B bus hub, and projection 12 is covered in the upper of hexagon flange.The thickness of recessed portion 11 is slightly less than the hexagon flange thickness that the 1553B bus hub carries, and guarantees that the pressing plate boss is pressed on the hexagon flange securely
Be provided with boss 21 with pressing plate 1 relative locating on framework 2, the space between boss 21 and the recessed portion 11 can hold the hexagon flange, and is affixed with another side of hexagon flange after installing.The consistency of thickness that the thickness of boss 21 and 1553B bus hub carry hexagonal flange is 2mm.
Processing is convenient in the design that boss 21 is set on the installation frame 2 and dimensional tolerance is controlled easily, the stopping means when not only installing as socket, and after socket installs as the anti-rotation device of socket, increase the reliability of assembling and use.
As shown in Figure 2, the installing hole 5 and the through hole 6 that have the 1553B bus hub on the framework 2.The principle of this device is: the position by the 21 restriction 1553B bus hubs of the installing hole of opening 5 on the framework 2 and boss, cooperate again pressing plate 1, and realize shrinking back and rotate in the 1553B bus hub use procedure.The through hole 6 that is used for fixation clip 1 is
2.7 pressing plate is fixed with the screw of M2.5, so just can make press plate position adjustable, thereby eliminates the impact of mismachining tolerance and socket self error.So that pressing plate and 1553B bus hub fit tightly from flanged, in use do not shrink back, do not rotate.
In above-mentioned 1553B bus hub fixture, the thickness of pressing plate is 4mm, and step place concave surface thickness is 2-0.1mm, is slightly less than the thickness that the 1553B bus hub carries hexagonal flange, the step convex surface is than the high 1mm of concave surface, as anti-in the 1553B bus hub use procedure shrink back, anti-rotation device.
After the installation of this fixture, further as shown in Figure 3, the hexagonal flange of 1553B bus hub is fixed by the boss 21 of pressing plate 1 and framework 2.Projection 12 is pushed down the hexagon end face of flange of 1553B bus.Prevent that so not only the 1553B bus from use shrinking back from flanged, can also avoid the pressing plate convex surface not interfere with 1553B bus hub tail end, so that damage socket tail cable.
The utility model 1553B bus hub fixture has been applied to finish satisfactorily the multi-task in the ripe equipment at present, and the stability of its quality and high reliability obtain user's consistent favorable comment.
The content that is not described in detail in the utility model specification belongs to this area professional and technical personnel's known technology.
