Description

Technical Field

[0001] The invention relates to the technical field of aircraft cabin control devices, in particular to a multi-channel interconnected cable structure of an aircraft cabin control box. Background Art

[0002] The aircraft cabin control box is a device that controls other signal mechanisms in the cabin through a control system. During use, it needs to overcome the test of environmental tolerance. It must tolerate natural environments including high and low temperatures, temperature shock, salt spray, mold, acidic atmosphere, sand and dust, rain, solar radiation, and other environments. It must tolerate mechanical environments including impact, acceleration, and other aircraft environments. The cables in the box are used to interconnect the control system and the cabin signal mechanism. Cables play a very important role in the aircraft cabin control box. When designing them, it is necessary to ensure that they meet performance requirements, weight requirements, natural environment adaptability, mechanical environment adaptability, corrosion protection requirements, etc.

[0003] At the same time, the internal space of the control box is limited, and cable laying is difficult. Moreover, most of the cables transmit multi-terminal electrical signals. The most common method is to bundle the wires of multiple ports and directly weld them to the PCB (printed circuit board) in the control box. The advantage of this method is that no other electrical components are required, and the operation is time-saving and labor-saving, but the defects are also very obvious. The connection between the wires and the PCB board is not stable enough. During use, the wires will be broken at the connection with the PCB board after being subjected to force due to vibration or impact, resulting in failure of the electrical connection. In addition, when there are too many interconnected wires in the box, it is inevitable that the wire harness will be messy and the wires will be entangled, which will cause the wires to bear unnecessary external forces and weaken the stability and reliability of the cable structure. Therefore, there is an urgent need for a multi-channel interconnected cable structure for the control box in the aircraft cabin to solve the above-mentioned problems. Summary of the invention

[0004] In view of this, the present invention proposes a multi-channel interconnected cable structure for an aircraft cabin control box, which is applied to the technical field of aircraft cabin control devices to solve the technical problems of messy wiring harnesses, entangled wires, easy breakage, poor stability and short service life in existing aircraft cabin control boxes.

A termination branch wire harness is arranged in the termination connector, the termination connector comprises electrical connection components, a contact body and a square disc rubber pad, a pin contact body assembly, a guide pin and guide sleeve assembly, a limit nut and a limit nut are arranged between the rectangular electrical connector and the printed board electrical connector, the termination connector and the rectangular electrical connector are interconnected through a wire, a portion of the wire close to the termination connector is arranged as a termination branch line, a portion of the wire close to the rectangular electrical connector is arranged as a rectangular branch line, the termination branch line and the rectangular branch line are bundled into a cable trunk through a nylon silk rope, the rectangular electrical connector and the printed board electrical connector are interconnected after being plugged in through a contact component assembly, the printed board electrical connector and the control box circuit board are interconnected through pin welding, and finally multi-channel electrical signal transmission is completed.

[0007] Furthermore, there are four terminating connectors, each of which is bundled to the cable trunk through a corresponding terminating branch line, and is connected to the rectangular electrical connector through a rectangular branch line.

[0008] Furthermore, the identification sleeve is sleeved on the conductor and is arranged between the termination branch line and the rectangular branch line.

[0009] Furthermore, the rectangular electrical connector and the printed circuit board electrical connector are positioned by a guide pin and guide sleeve assembly and fixed by a limit nut and a limit nut. The limit nut is arranged on the printed circuit board electrical connector, and the limit nut is arranged on the rectangular electrical connector.

[0010] Furthermore, the guide pin and guide sleeve assembly includes a positioning guide pin and a positioning guide sleeve, the positioning guide pin is arranged on the rectangular electrical connector, and the positioning guide sleeve is arranged on the printed circuit board electrical connector. When the rectangular electrical connector and the printed circuit board electrical connector are docked, the positioning guide pin and the positioning guide sleeve are inserted and positioned to prevent the rectangular electrical connector and the printed circuit board electrical connector from being inserted incorrectly.

[0011] Furthermore, the jack contact assembly is arranged on an end of the printed circuit board electrical connector away from the rectangular electrical connector, and the jack contact assembly is welded and interconnected with the PCB board in the control box during use.

[0012] Furthermore, a terminal code is provided on the terminating electrical connector, and a cable model identification is provided on the identification sleeve.
