Description

Technical Field

[0001] The utility model belongs to the technical field of aviation plugs, and in particular relates to an aviation plug calibration device. Background Art

[0002] Aviation plug alignment devices are used to ensure the correct connections of various electrical and electronic systems on aircraft. These connections often involve complex wiring harnesses and multiple plugs, each with multiple pins that must precisely align their functions and positions. Ensuring the correctness of these connections is crucial during aircraft manufacturing, maintenance, or upgrades, as incorrect connections can lead to system failures, safety risks, and even accidents.

[0003] Chinese utility model patent CN211741356U discloses a device for quickly calibrating aviation plugs. The device includes a plug, a connecting cable, a terminal block, a marker, a multimeter, a first connector, a second connector, and a multimeter cable. The plug is connected to the terminal block via the connecting cable, which is also marked with a marker. The first and second connectors are seamlessly connected to the terminal block. The multimeter is connected to the first and second connectors via the multimeter cable. By switching the various functions of the multimeter, the aviation plug can be quickly calibrated. This device can safely, effectively, quickly, and accurately complete aviation plug calibration.

[0004] In the above technical solution, the plug is connected to the terminal block through multiple wires in the connecting cable. Marks are added to the terminal block and correspond one-to-one with the terminal numbers on the aviation plug. However, when the multiple wires in the connecting cable are connected to the multiple terminals in the plug, they are easily entangled, which brings a lot of inconvenience to subsequent maintenance. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned technical problems and provide an aviation plug calibration device, which can avoid entanglement and twisting of multiple wires in a connecting cable after being connected to multiple terminals, thereby facilitating later maintenance.

[0006] In view of this, the present invention provides an aviation plug calibration device, comprising: a plug body and a terminal block, wherein one end of the plug body is provided with a connecting cylinder, a connecting cable is installed in the connecting cylinder, and a plurality of wires are provided in the connecting cable, and the plug body is connected to the terminal block via the plurality of wires. The present invention is characterized in that it further comprises:

[0007] Two curved partition plates, the two curved partition plates are symmetrically installed in the connecting tube, and the upper and lower ends of the outer wall of the connecting tube are provided with fixing devices for fixing the two curved partition plates;

[0008] A limiting component is used to fix the connecting cable in the connecting cylinder, and the limiting component is arranged at the outer end of the connecting cylinder.

[0009] In this technical solution, the design of two curved separators can effectively separate the multiple wires in the cable to prevent them from being entangled or twisted during the connection process, ensuring that each wire can be independently and smoothly connected to the corresponding terminal. The two curved separators are limited by a fixing device to provide stability for the curved separators to prevent them from falling. The positioning of the cable by the fixing assembly can ensure the stability of the cable during the connection process and reduce the risk of wire displacement or breakage due to vibration or external force.

[0010] In the above technical solution, further, outer walls at both ends of the connecting tube are provided with sliding grooves for the curved partition plate to slide out.

[0011] In the above technical solution, further, the fixing device includes: a fixing box, a sliding opening is symmetrically installed on the upper surface of the fixing box, a pull plate is slidably connected in the sliding opening, the bottom end of the pull plate is fixedly connected to a limiting plate, one side of the limiting plate is connected to an insert, one end of the insert passes through the fixing box and extends to the outside of the fixing box.

[0012] In the above technical solution, further, the upper and lower ends of the curved partition plate are provided with limit openings adapted to the inserts.

[0013] In this technical solution, the outer walls at the upper and lower ends of the connecting tube are provided with sliding grooves for the curved partition plate to slide out, so as to install or disassemble the curved partition plate. When installing the curved partition plate, the two pull plates are pulled inward, thereby driving the two plug-ins on both sides of the fixed box to move into the cavity, and then the curved partition plate is slid into the sliding groove, and then the pull plate is released. Under the action of the reset spring, the plug-ins on both sides of the fixed box move outward and insert into the limit openings at the upper and lower ends of the tight curved partition plate, thereby fixing the curved partition plate in the sliding groove.

[0014] In the above technical solution, further, a cavity is provided in the fixing box, a partition is provided in the middle of the cavity, and return springs are provided on both sides of the partition, one end of the return spring is fixedly connected to the partition, and the other end is fixedly connected to the limit plate.

[0015] In the above technical solution, further, a plurality of terminals are provided in the plug body, a first mark is added to each of the plurality of terminals, and a second mark that matches the first mark is also added to each of the terminal blocks.

[0016] In this technical solution, the design of the first and second identifiers helps ensure that the wires are correctly connected to the corresponding terminals, reducing the risk of circuit failure or equipment damage due to connection errors. During later installation or maintenance, the first and second identifiers can help maintenance personnel quickly locate and replace them.

[0017] In the above technical solution, further, the limiting assembly includes: two fixing plates, the two fixing plates are symmetrically installed on both sides of the connecting tube, a locking knob is threadedly installed on the fixing plate, and one end of the locking knob passes through the fixing plate and is connected to a clamping plate.

[0018] In this technical solution, the locking knob is rotated according to the cable diameter and the required fixing force. Rotating the knob causes it to move forward or backward along the thread, thereby driving the clamping plate closer to or away from the cable, thereby achieving the fixing and removal of the connecting cable.

[0019] The beneficial effects of the utility model are:

[0020] 1. The design of the two curved separators can effectively separate the multiple wires in the cable, preventing them from getting entangled or twisted during the connection process, ensuring that each wire can be independently and smoothly connected to the corresponding terminal. The two curved separators are limited by the fixing device to provide stability to prevent them from falling. The positioning of the cable by the fixing component can ensure the stability of the cable during the connection process and reduce the risk of wire displacement or breakage due to vibration or external force.

[0021] 2. The design of the first and second identifiers helps ensure that the wires are correctly connected to the corresponding terminals, reducing the risk of circuit failure or equipment damage caused by incorrect connections. During later installation or maintenance, the first and second identifiers can help maintenance personnel quickly locate and replace the wires. BRIEF DESCRIPTION OF THE DRAWINGS
