Description

Technical Field

[0001] The utility model relates to the technical field of aviation plugs, in particular to an aviation plug with stable connection. Background Art

[0002] Aviation plugs, also known as aviation jacks, are electromechanical components that connect electrical circuits and are widely used in aerospace, defense, electronic communications, industrial machinery, medical equipment, new energy and other fields. It is a very important component of avionics equipment and is used to connect electrical and electronic systems. Aviation plugs play a role in connecting or disconnecting circuits in aircraft, ships, vehicles and other transportation vehicles.

[0003] In the current use of aviation plugs, after being plugged in, the aviation plug is mostly plugged in and matched with the socket through the friction between the plug and the socket. However, in a long-term bumpy working environment, the connection between the plug and the socket is easily loosened due to vibration, resulting in poor contact or even detachment. The stability of the connection is low, and there are certain safety hazards. In view of this, we propose an aviation plug with a stable connection. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide an aviation plug with a stable connection to solve the problem that during the use of the current aviation plug, the connection between the plug and the socket is easily loosened due to vibration, resulting in poor contact or even separation, and the connection is less stable, which poses certain safety hazards.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing an aviation plug with a stable connection, including a socket body and a plug body inserted in the socket body;

[0006] A support ring is fixedly arranged on the outer edge surface of the plug body, and a hanging self-locking mechanism is arranged on one side of the outer edge surface of the support ring. A threaded knob is threadedly mounted on the outer edge surface of the socket body, and a plurality of hanging grooves for hanging and connecting the hanging self-locking mechanism are arranged in a circular array on the outer edge surface of the threaded knob.

[0007] The hanging self-locking mechanism includes a plurality of reset mechanisms arranged in a circular array on one side of the outer edge surface of the support ring and a plurality of support arms fixedly mounted on the corresponding reset mechanisms. The ends of the plurality of support arms away from the reset mechanisms are all constructed with hanging keys that are plugged into and cooperate with the corresponding hanging grooves, and elastic strips are fixedly arranged between the plurality of adjacent support arms to realize the reset of the support arms.

[0008] Preferably, the resetting mechanism comprises two supports, the two supports are constructed on one side of the outer edge surface of the support ring, and the facing surfaces of the two supports are both provided with cavities.

[0009] Preferably, a shaft is rotatably mounted between the two cavities, and the support arm is fixedly mounted on the outer edge surface of the shaft.

[0010] Preferably, both ends of the outer edge surface of the shaft rod are sleeved with torsion springs arranged in the cavity, and both ends of the torsion spring are respectively fixed to the inner wall of the cavity and the outer edge surface of the shaft rod.

[0011] Preferably, a support rib is centrally configured on one side of the bottom end of the support arm close to the reset mechanism, and the support rib abuts against the outer edge surface of the support ring.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model realizes self-locking after the plug body is inserted into the socket body through the hanging self-locking mechanism provided on the support ring and the threaded knob. When the plug body is inserted into the socket body, the hanging keys on the multiple support arms are inserted into the corresponding hanging grooves, and the insertion state is maintained with the help of multiple elastic strips and the reset mechanism, thereby ensuring the plug-in effect of the socket body and the plug body, avoiding the problem of loose connection due to vibration, reducing poor contact and separation, improving the stability of the plug-in, and eliminating safety hazards.

[0014] 2. The utility model helps the mounting key to rotate under the push of the threaded knob through the shaft rods arranged in the two supports, and twists the two torsion springs to store energy during the rotation. Therefore, when the pushing force is released, the two torsion springs help the mounting key on the support arm to be stably inserted into the mounting slot, further improving the stability of the plug-in and achieving a stable connection.
