[0002] In addition to meeting general performance requirements, a particularly important requirement for electrical connectors is that they must achieve good contact, reliable operation, and convenient maintenance. Whether they work reliably directly affects the normal operation of aircraft circuits and involves the safety of the entire mainframe. Therefore, the mainframe circuit has very strict requirements for the quality and reliability of electrical connectors. Also, because of the high quality and high reliability of electrical connectors, they are widely used in military systems such as aviation, aerospace, and national defense. Common classification methods for electrical connectors include appearance, structure, use, etc. However, during the use of current electrical connectors, there is a lack of a structure for limiting connecting wires on their surfaces. When the connecting wires are connected and subjected to external forces, they are prone to loosening. Therefore, we propose an electrical connector capable of preventing connecting wires from loosening to solve the above problems. Summary of the Utility Model

[0022] Embodiment

[0023] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, an electrical connector capable of preventing the connection wire from loosening proposed by an embodiment of the present utility model includes a first connector 1 and a second connector 2. Clips 3 are fixed on the upper and lower surfaces of the first connector 1 and the second connector 2. Covers 4 are snap-fitted on the surfaces of the clips 3. A protective plate 13 is fixed on one side wall of the two lower covers 4. Through holes are equidistantly formed on the side wall of the protective plate 13, which can play a role in dust prevention. The through holes enable the connection wire to pass through the protective plate 13 without interference. The two mutually attached covers 4 are fixedly connected by bolts. Anti-loosening components 5 for limiting the fixing screws of the connection wire are equidistantly arranged on the inner walls of the covers 4. Among them, wire bundling plates 6 are equidistantly fixed on the top inner walls of the two covers 4. Guide rods 7 slidably penetrate through the top parts of the other two covers 4 equidistantly. Limit plates 8 are fixed at the bottom ends of the guide rods 7. First springs 9 are fixed on the top parts of the limit plates 8. The top ends of the first springs 9 are respectively fixedly connected with the corresponding covers 4. Clamping blocks 10 are fixed on both side walls of the second connector 2. Clamping holes 11 are formed on the side walls of the clamping blocks 10. A clamping component 12 for clamping the clamping holes 11 is arranged on the outer wall of the first connector 1. When using this connector, after the connection wire between the first connector 1 and the second connector 2 is fixed, the cover 4 with the wire bundling plate 6 can be first snap-fitted on the surface of the first connector 1 or the second connector 2. Subsequently, the connection wire can be sorted and placed inside the wire bundling plate 6. Then, the upper cover 4 is snap-fitted and fixed. After snap-fitting, the anti-loosening components 5 at this time will respectively limit the fastening screws of the connection wire to prevent them from loosening. The connection wire can be limited and fixed by using the provided limit plates 8 and wire bundling plates 6. And under the action of the first springs 9, the limit plates 8 can be buffered, so as to avoid damage to the connection wire caused by excessive pressing force on the connection wire.

[0024] As Figure 3 shown, in some embodiments, the anti-loosening component 5 includes cylinders 501 equidistantly fixed on the inner wall of the cover 4. Pressure plates 502 are arranged inside the cylinders 501. Second springs 503 are fixed on the pressure plates 502. The other ends of the second springs 503 are respectively fixedly connected with the corresponding covers 4. When in use, the cylinders 501 will sleeved the fastening screws of the connection wire inside them. Under the action of the compressed second springs 503, the top of the screws can be squeezed and limited by the pressure plates 502, so as to avoid their loosening.

[0025] As Figure 1 、 Figure 2 and Figure 4As shown, in some embodiments, the snap - fit component 12 includes two third springs 1201 fixed to the first connector 1. The other ends of the third springs 1201 are both fixed with a moving plate 1202. Anti - slip rubber pads 1205 are fixed to one side wall of the moving plate 1202. When operating the moving plate 1202, the friction between the hand and its surface can be increased, thus achieving an anti - slip effect. Protrusions 1203 adapted to the card holes 11 are fixed to one side wall of the moving plate 1202. Telescopic rods 1204 are fixed to both side walls of the first connector 1, and the other ends of the telescopic rods 1204 are respectively fixedly connected to the corresponding moving plates 1202. When in use, when the first connector 1 and the second connector 2 are plugged together, the two moving plates 1202 can be simultaneously squeezed by hand. At this time, the third springs 1201 will be in a compressed state. After the first connector 1 and the second connector 2 are plugged together and the moving plates 1202 are released, at this time, under the restoring force of the third springs 1201, the protrusions 1203 will be respectively snapped into the interior of the card holes 11, thereby realizing the plug - in fixation of the two. When separating, the above operation can be repeated. By using the provided telescopic rods 1204, the moving plates 1202 can be supported and guided.

[0026] As Figure 1 As shown, in some embodiments, a surrounding frame 14 is fixed to the surface of the first connector 1, and a sealing plate 15 adapted to the surrounding frame 14 is fixed to the surface of the second connector 2. A sealing ring 16 is fixed inside the sealing plate 15. When the first connector 1 and the second connector 2 are plugged together, the two can be fitted more closely, thus playing a role in dust prevention and sealing.

[0027] Finally, it should be noted that the above - mentioned are only the preferred embodiments of the present invention and are not used to limit the present invention.
