Description

Technical Field

[0001] This utility model relates to the field of aircraft technology, specifically to a detachable aircraft wiring harness connector. Background Technology

[0002] For electric vertical takeoff and landing (EVTOL) aircraft, batteries are used as the power source, and motors supply power to the batteries. High-voltage wiring harnesses connect the motors and batteries. To meet the requirements of vertical takeoff and landing, a high-power motor is needed. However, when transmitting large currents, the high-voltage wiring harnesses generate heat, which can easily cause a fire. Therefore, thicker high-voltage wiring harnesses are required to reduce resistance and thus reduce heat generation. At the same time, thicker wiring harnesses are heavier, making installation and disassembly more difficult. For example, in a 2.5-ton class EVTOL aircraft, the diameter of a single high-voltage wiring harness is approximately 17mm, and the total weight of the high-voltage wiring harness exceeds 100kg. For high-voltage wiring harnesses of this weight, the strength of the structural connections must be considered.

[0003] Chinese utility model patents, Publication No. CN111308618B and Application No. CN201911099757.X, disclose a pluggable active optical connector and a data transmission system. The device is modular with one or more channels and converts electrical signals into optical signals and vice versa. On one side, the device has a pluggable electrical interface for a field replaceable unit (LRU); on the other side, the device has a pluggable optical interface side for the aircraft's fiber optic cabling bundle. The device can accommodate different types of LRUs, including rack-mounted LRUs and bolt-mounted LRUs. The connector's separation surface is a flat plate, which does not allow for increased cabling slack.

[0004] Therefore, we propose a detachable aircraft wiring harness connector to solve the above problems. Utility Model Content

[0006] (II) Technical Solution To achieve the aforementioned goals of adjusting the wiring harness allowance according to usage and facilitating installation, this utility model provides the following technical solution: a detachable aircraft wiring harness connector, comprising a detachable base and a detachable box. One side of the detachable box is an opening, the size of which is determined according to the diameter of the wiring harness. The other side has a through-hole, the size of which is also determined according to the diameter of the wiring harness. A socket connector is also provided on the side of the detachable box with the through-hole, for connecting other devices. Both sides of the detachable base have through-holes, the size of which is determined according to the diameter of the wiring harness. The detachable base is fixedly connected to the detachable box, with two connection methods: one is that the detachable base extends into the detachable box through the opening and is fixedly connected to the detachable box; the other is that the detachable box extends into the detachable base through the through-hole and is fixedly connected to the detachable base. The wiring harness passes through the through-holes of the detachable base and the detachable box and connects to the socket connector.

[0007] As a further optimization of this utility model: the separation base includes a structural plate and a base, and double ear support plates are provided on both sides of the base. The base is fixed to the structural plate by the double ear support plates and screws and nuts.

By fitting the separation box over the base, the stability between the base and the separation box can be improved.

[0009] As a further optimization of this utility model: the opposite surfaces of the base are provided with multiple mounting holes along the wire harness direction, and a support plate nut is fixedly connected in the mounting holes. By setting multiple mounting holes and support plate nuts, the installation position of the screws can be controlled, thereby adjusting the position between the base and the separation box and controlling the length between the separation box and the base.

[0010] As a further optimization of this utility model: screws are provided on the opposite surfaces of the separation box, and the screws are connected with the tray nut to fix the separation box and the separation base. The separation box and the base can be fixed together by fixing the screws and the tray nut.

By fitting the base over the separation box, the stability between the base and the separation box can be improved.

[0012] As a further optimization of this utility model: the opposite surfaces of the separation box are provided with multiple mounting holes along the wire harness direction, and a support plate nut is fixedly connected in the mounting holes. By setting multiple mounting holes and support plate nuts, the installation position of the screw can be controlled, thereby adjusting the position between the base and the separation box and controlling the length between the separation box and the base.

[0013] As a further optimization of this utility model: screws are provided on the opposite surfaces of the base, and the screws are connected with the tray nut to fix the separation box and the separation base. The separation box and the base can be fixed together by fixing the screws and the tray nut.

[0014] As a further optimization of this utility model: the socket connector and the separation box are fixed by screws and a bracket nut, which facilitates the installation and disassembly of the socket connector.

[0015] As a further optimization of this utility model: the screw is a GB / T 70.1 M5 screw, and the plate nut is a GB / T 889.1 M5 anti-loosening self-locking nut, which further improves the stability between the separation box and the separation base.

[0016] (III) Beneficial Effects Compared with the prior art, this utility model provides a detachable aircraft wiring harness connector, which has the following advantages: 1. The aircraft wiring harness connector has screw holes of different heights on the side of the box-type split surface base. Rivets and support nuts are pre-installed on the inside of the holes. When the box-type split surface is connected, the wiring harness allowance can be controlled by fixing the holes of different heights on the side.

[0017] 2. The aircraft wiring harness connector has pre-installed support nuts and rivets in both the side holes of the box-type split surface base and the fixing holes of the box-type split surface connector. Therefore, workers only need a single tool to operate when installing the connector, avoiding the complexity of using tools. Attached Figure Description
