DETAILED DESCRIPTION

[0039] The following will be described in detail in combination with the accompanying drawings. Figures 1-6 The present application will be further described in detail.

[0040] The plug 100 in the present patent refers to an airborne communication device, including but not limited to a power amplifier unit of an airborne long-wave transmitter, a DAM transmitter, a lockout crosslinking device, etc.

[0041] The collision coupling mechanism provided by the embodiment of the present application is described in detail with reference to the accompanying drawings. Figure 1, including the impact plate 10, the guide plate 20 and the switch insulating block 30. Wherein, the impact plate 10 is used for bearing the main load and providing the mounting port of the impact plug. The guide plate 20 is fixed on the side of the impact plate 10, and the switch insulating block 30 is installed on the impact plate 10. The input end of the switch insulating block 30 is connected with the signal input source. The guide plate 20 is configured to enable the plug-in 100 to slide on the guide plate 20, so as to realize the butt joint of the coupling end of the plug-in 100 and the output end of the switch insulating block 30, and the effects of simplifying the equipment coupling and improving the convenience of the equipment operation are achieved. Through the design of the structure, the problem of complex operation of the traditional coupling mode caused by the small space is solved, and the overall stability of the equipment is improved.

[0042] With reference to Figure 1 and Figure 2 In the embodiment, the impact plate 10 is a cuboid plate. Both sides of the impact plate 10 are connected with the guide plate 20. The symmetric guide plate 20 is used for guiding the plug-in 100, so as to improve the moving precision of the plug-in 100. Wherein, the impact plate 10 and the guide plate 20 can be welded or detachably connected through screws. Preferably, the impact plate 10 is made of aluminum alloy material and is subjected to oxidation protection treatment, so as to ensure that it has good corrosion resistance and high strength characteristics. In addition, the impact plate 10 is provided with a positioning pin insertion hole 11 at different positions of the plate surface. The plug-in 100 is provided with a positioning pin at the corresponding position. When the plug-in 100 is impacted, the positioning pin can be inserted into the positioning pin insertion hole 11, so as to further play a guiding and fixing role.

[0043] With reference to Figure 1 and Figure 3 Wherein, the switch insulating block 30 is an important carrier for realizing the power supply and tuning coupling of the impact coupling mechanism plug-in 100. The material of the switch insulating block 30 can be selected from epoxy phenolic glass cloth plate 3240N material. The surface is further protected by vacuum immersion insulating paint. This design can effectively increase the voltage strength and creepage distance, so that the equipment is more reliable.

[0044] With reference to Figure 3 and Figure 4 In the embodiment, the switch insulating block 30 includes two parts of the mounting part 31 and the connecting part 32. The mounting part 31 and the connecting part 32 can be an integral T-shaped structure. The side wall of the impact plate 10 is provided with a connecting part installation hole 12 penetrating through the side wall. The connecting part 32 can pass through the connecting part installation hole 12, and the side wall of the mounting part 31 abuts against the plate surface of the impact plate 10. At this time, the mounting part 31 can be detachably connected with the impact plate 10 through screws.

[0045] Meanwhile, the connecting part 32 is provided with a connecting hole 321 in the middle. The connecting hole 321 is provided with a conductive sheet assembly. The connecting hole 321 penetrates through the entire connecting part 32 and the mounting part 31. Optionally, the connecting hole 321 can be a square hole, a round hole or a polygonal hole.

[0046] With reference to Figure 4 and Figure 5 Specifically, the conductive sheet assembly is composed of a conductive sheet group 40 and a fastening assembly 50, wherein the conductive sheet group 40 is embedded in the connecting hole 321 and is responsible for signal transmission and power supply functions. The fastening assembly 50 is used to lock the conductive sheet group 40 in the connecting hole 321.

[0047] In this embodiment, the conductive sheet group 40 includes an outer conductive sheet 41 and an inner conductive sheet 42, which are arranged in a U shape as a whole, and the side edges of the outer conductive sheet 41 and the inner conductive sheet 42 are in contact. The connecting end of the plug-in device 100 can be inserted into the U-shaped opening of the outer conductive sheet 41 and the inner conductive sheet 42 to achieve signal connection.

[0048] The side surface of the connecting portion 32 is provided with a pressing block mounting hole 322 which communicates with the connecting hole 321, and the pressing block mounting hole 322 is arranged close to the mounting portion 31. The fastening assembly 50 includes a pressing block 51 and a fastening piece 52. The pressing block 51 is inserted into the pressing block mounting hole 322 and abuts against the inner side wall of the U-shaped inner conductive sheet 42. The fastening piece 52 penetrates the inner conductive sheet 42 and the outer conductive sheet 41 and is threadedly connected with the pressing block 51. The operating end of the fastening piece 52 is located in the connecting hole 321, which effectively clamps and fixes the conductive sheet group 40 and improves the stability and conductivity of the connection.

[0049] Further, the hole opening of the pressing block mounting hole 322 is opposite to the inner wall of the connecting portion mounting hole 12, and the pressing block 51 and the inner wall of the connecting portion mounting hole 12 are filled with an insulating sealing block 53, and the pressing block 51 is a conductive block. Specifically, the insulating sealing block 53 is made of cured epoxy resin. During the assembly of the switch insulating block 30, after the pressing block 51 is inserted into the pressing block mounting hole 322, the hole opening of the pressing block mounting hole 322 is filled with epoxy resin, and then the connecting portion 32 is inserted into the connecting portion mounting hole 12. At this time, the inner wall of the connecting portion mounting hole 12 can limit the epoxy resin in a predetermined position, and after the epoxy resin is cured, the sealing function is realized.

[0050] In addition, the mounting portion 31 is provided with a wiring groove 311 which communicates with the connecting hole 321 on the side away from the connecting portion 32. The wiring in the wiring groove 311 enables the conductive sheet group 40 to communicate and connect with other plug-in devices 100.

[0051] In this embodiment, the switch insulating block 30 is integrally provided with four, corresponding to four plugs. After installation, the switch insulating block 30 separates the four plugs to form an "isolating wall" to cooperate with its inherent properties and protection to effectively increase the creepage distance and withstand voltage strength, thereby improving the reliability and safety of the equipment. In other embodiments, the number of switch insulating blocks 30 can also be designed according to the needs.

[0052] With reference to Figure 2The central part of the collision plate 10 is provided with a ventilation hole 13. In this way, on the one hand, the air circulation can reduce the heat accumulation and maintain a constant working temperature; on the other hand, it also plays a role in reducing the weight, making the whole more portable and easy to move. Optionally, a cooling fan can be installed at the ventilation hole 13, which is aimed at the ventilation hole of the plug-in 100 to improve the heat dissipation efficiency of the plug-in 100.

[0053] In addition, the collision plate 10 is also specially reserved for some standard size collision plug ports 14 for subsequent expansion use, so that there is no need to worry about the incompatibility when replacing accessories in the future, which saves cost and improves flexibility.

[0054] Referring to Figure 2 and Figure 6 The collision coupling mechanism further comprises a guide rail 60 and a sliding bar 61 arranged between the guide plate 20 and the plug-in 100. The guide rail 60 is provided with a guide groove 601, and the groove wall spacing of the guide groove 601 gradually decreases in the direction close to the collision plate 10. The sliding bar 61 is slidably arranged in the guide groove 601, and the size of the sliding bar 61 is constant along the length direction of the sliding bar 61.

[0055] In this embodiment, the guide rail 60 is installed on the side of the guide plate 20, and the sliding bar 61 is installed on the side of the plug-in 100. The guide plate 20 is fixedly connected to the inner wall of the cabinet by screws. When the collision coupling is needed, the plug-in 100 is slid to make the plug-in 100 abut with the switch insulating block 30 and the corresponding plug port.

[0056] In this embodiment, the groove wall spacing of the guide groove 601 gradually decreases in a stepped manner in the direction close to the collision plate 10. In the process of gradually approaching the collision plate 10, the position of the plug-in 100 is gradually stabilized. When the plug-in 100 is ready to be coupled with the collision plate 10, the guide rail 60 and the sliding bar 61 have a certain pre-tightening force, which further improves the reliability and stability of the coupling.

[0057] In addition, the front end of the sliding bar 61 is provided with a tapered end 611, which can guide the plug-in 100 to be more smoothly coupled with the collision coupling mechanism, reduce the positional deviation in the coupling process, and improve the precision and efficiency of the plug-in 100.

[0058] The implementation principle of this embodiment is that through the design of the collision coupling mechanism, not only the operation inconvenience caused by traditional cable connection is solved, but also the reliability and convenience of equipment coupling are significantly enhanced. Especially in the application scene with limited space, such improvement measures are particularly critical. The main components made of aluminum alloy ensure the stability and durability of the structure, and the introduction of various auxiliary facilities such as the positioning pin and the collision plug port 14 effectively makes up for the many shortcomings caused by relying on hard connection alone, so that the overall solution has more advantages and competitiveness.

[0059] The application further discloses a cabinet, which contains the collision connecting mechanism.

[0060] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
