However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0022] Example

[0023] See also Figure 1-Figure 4 , a rack cable assembly capable of realizing floating blind plugging function, comprising:

[0024] The blind-plug floating docking mechanism comprises a floating component 1 and a guiding docking component 2, wherein the floating component 1 is provided with a first socket 101, and the guiding docking component 2 is provided with a first plug 201 and a second plug 202 electrically connected to each other, wherein the first plug 201 on the guiding docking component 2 is used for mating with the first socket 101, and the second plug 202 of the guiding docking component 2 is used for being plugged and fixed with a second socket 3 of an aircraft suspension;

[0025] Connector joints 4 , the number of which is multiple, and the multiple connector joints 4 are communicatively connected to the socket of the floating component 1 via cables 5 .

[0026] In this embodiment, the blind-plug floating docking mechanism adopts a split structure, which is composed of a floating component 1 and a guiding docking component 2. When installing the hanging object, first remove the guiding docking component 2 and screw the second plug 202 to the second socket 3 on the hanging object, and then dock the hanging object with the guiding docking component 2 with the floating component 1 as a whole; during the docking process, the main key position and the inclined surface of the guiding docking component 2 are used to guide and ensure the blind plugging of the first plug 201 and the first socket 101, so as to achieve the docking and locking of the plug and the socket. In addition, the electrical interconnection between the aircraft and the hanging object is achieved through multiple connector joints 4 and cables 5, which meets the functions of detecting the state of the hanging object and implementing the hanging object delivery. The present invention can realize blind plugging and direct plugging between the cable 5 and the hanging object, and can achieve a slight floating after plugging, so that the connection between the cable 5 and the hanging object is more stable, and when the hanging object needs to be delivered, the cable 5 can be automatically separated from the hanging object.

[0027] In this embodiment, the floating assembly 1 of the blind-plug floating docking mechanism includes a mounting plate 102, and the first socket 101 is fixedly connected to the mounting plate 102 through four limit springs 103. The floating assembly 1 and the mounting plate 102 have a floating gap to achieve circumferential floating, meet the tolerance compensation of the hanging object, and make the connection between the cable 5 and the missile more stable. In this embodiment, the floating assembly 1 and the mounting plate 102 have a floating gap to meet the horizontal floating of ±6mm and the vertical floating of ±2mm.

[0028] In this embodiment, the cable 5 is provided with a low-frequency shielded conductor and a high-frequency shielded conductor, and a high- and low-frequency mixed structure is applied to realize different types of signal transmission and meet the transmission function of a complex structure.

[0029] Low-frequency signals can be directly split by switching. However, high-frequency signals cannot be directly split by switching. Therefore, in this embodiment, a coupler 9 is provided on the high-frequency shielded wire that is connected to the blind-plug floating docking mechanism. When there are multiple high-frequency signals in the high-frequency shielded wire, the coupler 9 is used to split the signals to ensure that the high-frequency signal loss is small.

[0030] In this embodiment, the low-frequency shielded wire and the high-frequency shielded wire are respectively provided with an anti-wave sleeve 6 and a tape sleeve 7 outside the wiring harness, which can effectively resist electromagnetic pulses and electromagnetic radiation from the outside of the wire, so that the cable 5 component has excellent anti-electromagnetic interference capability. In addition, the wire shielding layer and the anti-wave sleeve 6 at the connection between the connector joint 4 and the cable 5 and the connection between the blind plug floating docking mechanism and the cable 5 are mutually conductive, and a 360-degree shell connection is adopted between the shell of the connector joint 4 and the shell of the blind plug floating docking mechanism. The cable 5 component has the function of high- and low-frequency mixed signal transmission, and also has good anti-electromagnetic interference capability, realizes the electrical interconnection between the aircraft and the suspended object, satisfies the functions of detecting the state monitoring of the suspended object and implementing the release of the suspended object, especially when the suspended object needs to be released, it can ensure the automatic separation of the cable 5 and the suspended object.

[0031] In this embodiment, a double-wall heat shrink tube 8 is provided at the connection between the connector joint 4 and the outer layer of the cable 5. By blowing and shrinking the double-wall heat shrink tube 8 outside the end of the connector joint 4 for protection, a more aesthetic effect is achieved.
