Detailed Description
The missile comprehensive maintenance interface is designed into a multi-cavity comprehensive connector and comprises a socket and a plug, and the plug is matched with the socket to realize electric signal connection. The locking device comprises a socket bracket and a plug adapter frame. The socket is provided with a mounting flange structure, and the socket support is connected with the socket flange through screws to realize socket fixation. The socket support can adopt a split type structure to adapt to the structural condition of the mounting position on the bullet, and the socket and the bullet body structure are fixedly mounted through the socket support.
The plug is provided with a mounting flange structure, and the plug transfer frame is connected with the plug flange through a screw. In order to distinguish the plugs in various states, mounting holes with different specifications and sizes are adopted in the local design of different plug adapter frames. The socket bracket is provided with mounting holes corresponding to different plug adapter frames.
After the plug is in butt joint with the socket in place, the plug transfer frame is connected with the socket support through the screws, and the mechanical locking of the connection of the plug and the socket is realized through the fastening of the connecting screws.
The invention is applied to the structural design of the comprehensive maintenance test interface of a certain type of missile. The connector socket is a multi-cavity connector integrating multiple types of electric signals, and the connector is not connected with a locking mechanism. The connector socket is elastically mounted as shown in fig. 1, and the bracket adopts a split design and comprises a bracket I1 and a bracket II4 which are respectively mounted on two sides of the socket. As can be seen from the figure, the support I1 and the support II4 are in a U-shaped frame structure form, so that the requirement on installation strength is met, and meanwhile, the socket cable can penetrate out from the middle of the support, so that the purpose of reserving a cable routing channel is achieved. The socket has a mounting flange structure, the upper end of the U-shaped support is connected with the socket flange through a socket fastening screw 3, and the lower end of the U-shaped support is connected with the support and the elastomer mounting structure 6 through a support fastening screw 5.
The plug is provided with a mounting flange structure, and the plug transfer frame is connected with the plug flange through a screw. In order to distinguish the plugs in two states, the local design of the adapter frame adopts two screw mounting holes with different specifications and sizes. Fig. 2 and 3 are schematic diagrams showing two types of plug transition frames, i.e., an a-type plug transition frame 8 and a B-type plug transition frame 10. 2A-type fastening screw mounting holes 7 with the same size are respectively designed at the positions which are symmetrical with a central symmetry axis on the two corresponding sides of the A-type plug adapter frame 8; step holes, namely B-type fastening screw mounting holes 9 are respectively designed on two corresponding sides of the B-type plug adapter frame on the central symmetry axis, and the size of the central hole is different from that of the A-type fastening screw mounting holes 7; socket support I and support II correspond A type plug to change frame 8 respectively and are equipped with two and A type fastening screw mounting hole 7 size and position assorted screw mounting hole, simultaneously socket support I and support II correspond B type plug to change frame 10 respectively and are equipped with one and B type fastening screw mounting hole 9 size and position assorted screw mounting hole.
As shown in fig. 2, no screw mounting hole is provided in the direction of the central symmetry axis of the a-type plug transition frame 8, and an a-type fastening screw mounting hole 7 having a size of r2.7mm is provided at the symmetrical position 4. In the design of the B-type plug adapter frame 10, 4 screw mounting holes in the design of the A-type plug adapter frame 8 are eliminated, and two stepped holes, namely B-type fastening screw mounting holes 9, are designed on a central symmetry axis. The sectional structure of the B-type fastening screw mounting hole 9 can be seen from the sectional view of the B-type plug adapter frame a-a in fig. 4, and the central hole of the B-type fastening screw mounting hole 9 has a size of r3.25mm. And mounting screws with different sizes are correspondingly configured according to the design of the two mounting holes. As shown in fig. 5, an a-type connection fastening screw 12 disposed corresponding to the a-type plug 11 is inserted through a screw hole of the a-type plug adapter frame 8, thereby fastening the a-type plug 11 to the jack mount. As shown in fig. 6, a B-type connection fastening screw 14 disposed corresponding to the B-type plug 13 is inserted through a screw hole of the B-type plug adaptor frame 10, thereby fastening the B-type plug 13 to the jack mount. The design can realize the distinguishing of two different plugs.
