Technical Field

[0001] This invention relates to a connector used in aviation equipment, and more specifically to an avionics connector interface distribution device. Background Technology

[0002] Avionics refers to the sum of all electronic systems on an aircraft. A basic avionics system consists of multiple systems, including communication, navigation, and display management, all connected by wiring harnesses. Because aviation equipment has numerous wiring harnesses, maintenance of these harnesses is cumbersome, often requiring the disassembly of multiple connectors. Furthermore, using the same connectors for some signal lines makes installation even more inconvenient, and the harnesses are prone to tangling. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide an aviation electronic connector interface distribution device to solve the problems of the large number of wire harnesses in aviation equipment, the cumbersome inspection of wire harness connectors during maintenance, the need to disassemble multiple connectors, the inconvenience of installing some signal lines using the same connectors, and the easy entanglement between wire harnesses.

[0004] To solve the above-mentioned technical problems, the present invention provides an avionics connector interface distribution device, including a splitter and a top cover mounted on the top of the splitter. The top of the top cover has a plurality of cable hub terminals arranged thereon. Each cable hub terminal includes a cable hub base fixedly mounted on the top of the top cover, a terminal block mounted on the cable hub base, and a cable management frame mounted on the terminal block. The cable management frame includes a terminal conversion structure for distributing and connecting terminals of different cable bundles and a top frame for organizing the cable bundles. The bottom of the terminal block is welded and fixed with pins for leading the cable bundle signals to the terminal block.

[0005] The bottom of the top cover is provided with a latch, and the top cover is connected to the splitter through the bottom latch. The bottom of the splitter is provided with a protective sleeve.

[0006] The terminal adapter structure includes a housing located at the bottom of the top frame, a terminal assembly frame with adapter terminals fixedly installed inside the housing, and male and female connectors respectively installed at both ends of the adapter terminals.

[0007] The top frame includes a top frame base fixedly installed on the top of the housing, a movable ring set on the top frame base, a flip bar and a limiting ring movably installed on both sides of the movable ring, and a limiting frame movably installed in the middle of the movable ring. The side of the limiting ring cooperates with the top end of the flip bar and the limiting frame is located below the top end.

[0008] The terminal assembly frame includes a fixed frame with two or more movable slots. The adapter terminal is nested in each of the movable slots. The fixed frame is provided with mounting holes corresponding to each of the movable slots. Locking bolts for fixing the adapter terminal can be connected in series in the mounting holes.

[0009] The limiting ring includes a ring body with a groove on its surface and an extended inner plate nested in the inner cavity of the groove.

[0010] The notch in the ring is less than 1 / 2 of the circumference.

[0011] The surface of the extended inner plate is provided with raised movable blocks.

[0012] The connector is hinged with a snap fastener, and the cable management rack is provided with a locking pin that cooperates with the snap fastener.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The wiring harnesses to be led out are integrated by a splitter, then covered by a top cover. The harness signals are led out to the terminal block via pins for easy signal classification and maintenance. Furthermore, a terminal assembly rack consisting of a mounting bracket and adapter terminals allows the wiring harness orientation to be controlled via the adapter terminals, facilitating wiring harness organization and marking. The mounting bracket has movable slots that engage with the adapter terminals, enabling easy replacement of the adapter terminals to accommodate different terminals and facilitating quick connection and maintenance. Limiting rings and flip rods designed in the top frame further enhance the convenience. The limiting bracket organizes the wire harness, allowing it to be bundled into one strand, especially through the clamping of the limiting rings. It can also unfold the three strands. The limiting rings on both sides and the limiting bracket in the middle ensure that the wire harness is in a reasonable position, avoiding tangling and facilitating wire management, which is convenient for later maintenance. Thus, through the specific structural design of this invention, the problems of the prior art, which involves numerous wire harnesses in aviation equipment, making wire harness connector maintenance troublesome and requiring the disassembly of multiple connectors, and making the installation of some signal lines using the same connectors even more inconvenient, and easily causing tangling between wire harnesses, can be avoided.

The cable management frame a1 is installed on the terminal block a5, and the split-locking latch a3 is hinged to the terminal block a5. The cable management rack a1 is equipped with a locking pin that engages with the snap-fit ​​fastener a3, thereby enabling the cable management rack a1 to engage with the terminal block a5. The terminal block a5 is fixed to the top of the cable hub base a7, and the pins a9 are soldered and fixed to the bottom of the terminal block a5, and the two are electrically connected. The cable management rack a1 includes a terminal adapter structure for distributing and transferring terminals of different cable bundles and a top frame 212 for organizing the cable bundles. The terminal adapter structure includes a housing 214 located at the bottom of the top frame 212 and a terminal collection rack 216 fixedly installed in the housing 214. The frame 212 communicates with the inner cavity of the housing 214. The housing 214 has limiting holes 218 on both sides and is connected to the terminal assembly frame 216 through these limiting holes 218. The terminal assembly frame 216 includes a movable slot 2160, a limiting bolt 2162, a fixing frame 2164, an adapter terminal 2166, and a locking bolt 2168. The fixing frame 2164 has two or more movable slots 2160, and the movable slots 2160 and the adapter terminal 2166 are nested together. The terminals installed on both sides of the adapter terminal 2166 are male on one end and female on the other, facilitating the fixing frame 2164. Adjusting terminal 164 allows for terminal alignment and engagement, improving connection efficiency and facilitating maintenance. Adapter terminals 2166 are categorized by frequency (high-frequency and low-frequency aviation connectors), shape (circular connectors), and application (rack-mounted, audio equipment, power supply, and special-purpose aviation connectors). Locking bolts 2168 penetrate the mounting holes at the front of the mounting bracket 2164 and engage with the internal threads of the adapter terminal 2166. The mounting bracket 2164 is connected to the housing 214 on both sides via limiting bolts 2162.

[0025] With this structural design, users can install the wire harness by cooperating with the mounting bracket 2164 and the adapter terminal 2166.

The surface of the extended inner plate 21c is provided with raised movable blocks to facilitate the extension and restrict the wire.

[0028] With this structural design, users can integrate the wire harnesses that need to be led out using the splitter 3, then cover them with the top cover 1, and lead the wire harness signals to the terminal block a5 through the pin a9 for easy classification of electrical signals and convenient maintenance and repair. The cable management frame a1 can be quickly disassembled through the snap-fit ​​buckle a3, making installation more convenient. The fixing frame 2164 inside the terminal collection frame 216 has multiple movable slots 2160, which can facilitate the replacement of the second adapter terminal 2166 and can be adapted to the terminal arrangement modification of different wire harnesses. After modification, the locking bolt 2168 is tightened to fix the adapter terminal 2166, and then the limiting bolt 2162 is tightened to the housing 214 to complete the fixation. After fixing, it can be directly plugged in and connected. Different plugs can be reasonably distributed and the appropriate adapter terminal 2166 can be selected for the adapter arrangement. After the arrangement is completed, it can be quickly installed through the snap-fit ​​buckle a3, making it more convenient to use.

[0029] In use, the present invention organizes the wire harness by means of the limiting rings, the flip rod, and the third limiting frame. The wire harness can be bundled into one strand and clamped by the limiting rings. Alternatively, the limiting rings and the flip rod can be unfolded under the action of the movable rings, and then the wire harness can be fixed in its respective limiting ring. The wire harness is then fixed by the extended inner plate. The limiting rings on both sides and the third limiting frame in the middle can keep the wire harness in a reasonable position, avoid tangling, facilitate wire management, and facilitate later maintenance.
