Description

Technical Field

[0001] This utility model belongs to the technical field of wire connection device, and more specifically, it relates to an aircraft assembly connector tooling. Background Technology

[0002] There are numerous electrical wires distributed throughout various components of an aircraft. These wires and cables can weigh thousands of kilograms in total and stretch for hundreds of kilometers. These cables are distributed inside the aircraft to resist external interference, so it is essential to ensure the strength of the connections.

[0003] However, existing wires and cables still have the following two shortcomings when splicing:

[0004] First, the lack of protective measures at the junction of the two wires makes the insulating tape at the junction prone to weathering and cracking, posing a safety hazard.

[0005] Secondly, when the wires are pulled by external force, the joint between the two wires is prone to tearing, which means that the joint strength between the two wires is insufficient. Utility Model Content

[0006] In order to at least partially solve the above-mentioned technical problems, this utility model provides an aircraft assembly joint tooling.

[0007] The purpose and effect of this utility model of an aircraft assembly joint tooling are achieved by the following specific technical means: an aircraft assembly joint tooling, including a first protective cover;

[0008] The main body of the first protective cover is a semi-circular structure, and a limiting ring is installed at each of the left and right ends of the first protective cover;

[0009] The second protective cover has the same structure as the first protective cover, and is located directly above the first protective cover. The second protective cover is rotatably connected to the first protective cover.

[0010] A connecting cylinder is fixedly installed on the outer end face of the limiting ring, and the inner end face of the connecting cylinder is flush with the inner end face of the limiting ring.

[0011] The elastic plate is fixedly installed on the outer end face of the connecting cylinder. There are four elastic plates arranged in a ring structure.

[0012] The locking blocks are provided in two symmetrical sets. The locking blocks have cavities inside and threads are provided at the front of the inner end face of the locking blocks.

[0013] Furthermore, the locking block has a frustum-shaped structure in the middle of its interior, and a circular hole at the rear of the locking block. Inclined pins are evenly installed on the inner end surface of the circular hole.

[0014] Furthermore, a long strip-shaped first connecting plate is installed on the surface of the first protective cover, and a through hole is opened on the surface of the first connecting plate. A second connecting plate is installed on the surface of the second protective cover, and the second connecting plate has the same structure as the first connecting plate.

[0015] Furthermore, the connecting cylinder has threads on its exterior, and the front end of the locking block is threadedly connected to the exterior of the connecting cylinder.

[0016] Furthermore, the outer end face of the elastic plate is inclined, and the inner end face of the elastic plate is arc-shaped.

[0017] Furthermore, an arc-shaped pressure strip is fixedly installed in front of the inner end face of the elastic plate, and rubber strips are evenly installed on the inner end face of the pressure strip.
