Description

Technical Field

[0001] This utility model relates to an adjustable bendable cable tail accessory, belonging to the field of aviation connector technology. Background Technology

[0002] Cable tail clips are an important component of electrical connectors. They provide clamping and protection for the cable, and are characterized by their simple appearance, compact structure, ease of installation, and high reliability. Current aerospace products generally use straight cable tail clips, but in confined spaces and complex structures, bent cable tail clips are typically used to prevent interference between the connector plug and the cable during installation. According to design requirements, when the connector plug or socket is installed with the tail clip, the keyway at one end of the connector must be at a certain angle. If this angle is not maintained, it can lead to difficulty in mating with the other end of the connector, requiring readjustment of the tail clip angle to ensure proper connector mating and avoid interference with surrounding components. Utility Model Content

[0005] Preferably, the adjustment part includes a rotating seat and a rotating inner threaded sleeve; the rotating seat includes a wire harness receiving cavity and an ear piece, the ear piece is disposed at the open end of the wire harness receiving cavity and is provided with a through hole opposite to it, an adjusting screw is installed in the through hole, and the connection and separation of the tail clip end and the connector end can be realized by tightening or loosening the adjusting screw; the rotating inner threaded sleeve is connected to the housing; the rotating seat is combined with the housing through the broken tooth structure on the rotating inner threaded sleeve.

[0006] Preferably, the adjusting screw is provided with a safety hole.

[0007] Preferably, the fixing part includes a cable clamp and a fixing screw; the cable clamp is used to fix the wire harness and is located at the other end of the adjusting part, and its movable end is connected and fixed to the adjusting part by the fixing screw.

[0008] Preferably, the fixing screw is provided with a safety hole.

[0009] Preferably, the outer threaded sleeve has an inner matching end tooth structure to ensure that the electrical connector completes self-locking after mating.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] 1. The matching end tooth structure (main groove key) of the external threaded sleeve and the broken tooth structure (slot) of the internal threaded sleeve can increase the convenience and stability of operation.

[0012] 2. In complex aircraft operating conditions, such as in areas with complex structures and confined spaces where electrical connectors are difficult to connect or cannot connect due to interference with surrounding surfaces, this tail accessory can be quickly adjusted, making it highly adaptable and practical, and reducing labor costs.

[0017] The following is in conjunction with the appendix Figure 1-3 The present invention is further described in detail as follows: An adjustable bent cable tail accessory controls the direction of the cable harness by quickly adjusting the angle of the tail clip. It includes a connector and a tail clip that are internally connected. The connector and the tail clip form a bent structure. The connector end is used to connect with another connector. It includes a housing 2 and an outer screw sleeve 1. The housing 2 is hollow inside, and the outer screw sleeve 1 is disposed at one end of the housing 2. The tail clip includes an adjustment part and a fixing part. The adjustment part is connected to the end of the housing 2 away from the outer screw sleeve 1 and is used to adjust the direction of the cable harness. The fixing part is disposed at the other end of the adjustment part and is used to fix the cable harness to prevent it from loosening and falling off.

[0018] In this embodiment, the main purpose of the adjustment part is to adjust the direction of the tail accessory. It includes a rotating seat 3 and a rotating inner threaded sleeve 5. The rotating seat 3 includes a wire harness receiving cavity and an ear piece. The ear piece is located at the open end of the wire harness receiving cavity and has a through hole. An adjusting screw 4 is installed in the through hole. By tightening or loosening the adjusting screw 4, the tail clip end and the connector end can be connected or separated. The rotating inner threaded sleeve 5 is connected to the housing 1. The rotating seat 3 is combined with the housing 1 through the broken tooth structure on the rotating inner threaded sleeve 5. Tightening the adjusting screw 4 makes the tail clip end and the connector end tightly connected. Loosening the adjusting screw 4 separates the tail clip end and the connector end. Adjusting the rotating seat 3 at a certain angle changes the direction of the tail clip end, which can achieve the purpose of avoiding interference.

[0019] The fixing part includes a cable clamp 6 and a fixing screw 7; the cable clamp 6 is used to fix the wire harness and is set at the other end of the rotating seat 3, and its movable end is connected and fixed to the rotating seat 3 by the fixing screw 7.

[0020] A safety hole is provided on the adjusting screw 4; a safety hole is provided on the fixing screw 7; a fuse is used for anti-loosening protection.

[0021] As a preferred embodiment of this invention, the plug or socket connection end of the electrical connector adopts a rotary connection, and the outer screw sleeve 1 connected to the tail accessory end can restrain the follower of the circular electrical connector accessory and allow it to rotate freely on it. The matching end tooth 8 structure inside the outer screw sleeve 1 ensures that the electrical connector completes self-locking after docking.

[0022] Pass the crimped (or soldered) wire harness or cable through the cable clamp 6 hole of the tail accessory. Crim the contacts according to the tools specified for electrical connectors. Place the accessory at a position greater than a certain length from the end of the wire harness, generally about 100mm. Use a wire-feeding tool to insert the contacts into the electrical connector. Before assembling with the connector, fill the tail clamp with pads as needed according to design requirements. Straighten the wire harness or cable and ensure a tight fit between the wire harness and the cable clamp 6 by rotating the tail accessory fixing screw 7 clockwise. Fix the connector socket or plug in the corresponding specification body mounting bracket. When assembling a connector with a bent tail accessory, generally when viewed from the front (mating end) of the connector, it should be at the 6 o'clock position. Position the connector's largest (main) keyway according to the design drawing in the direction required for fixing. Rotate the tail accessory outer threaded sleeve 1 until the connecting threaded sleeve can no longer be tightened, ensuring that the plug or socket is fully engaged with the end teeth 8 on the tail accessory. When adjusting the angle of the curved tail accessory, loosen the adjusting screw 4 with a wrench or other tool, adjust the angle of the rotating seat 3 by rotating the inner threaded sleeve 5 to achieve the desired angle, and then retighten the adjusting screw 4. After assembly, the threaded tail accessory needs to be secured by passing a fuse through the safety hole.
