[0022] like Figure 1As shown, an anti-disengagement connector includes a mounting panel 1 and a socket cover 2. A socket body 4 is mounted on the mounting panel 1, and a mounting bracket 10 is also mounted on the mounting panel 1, located on one side of the socket body 4. A shaft bracket 8 is also mounted on the mounting panel 1, located on the other side of the socket body 4. The socket cover 2 is mounted on the mounting bracket 10 via a first torsion spring assembly 3. A rotatable locking bracket 5 is mounted on the other end of the socket cover 2 via a second torsion spring assembly 7. When the socket cover 2 covers the socket body 4, the socket cover 2... The socket cover 2 is parallel to the mounting panel 1. At this time, the torsion spring of the first torsion spring assembly 3 generates a certain torque. When the socket cover 2 is flipped relative to the mounting panel 1, the torque generated by the torsion spring of the first torsion spring assembly 3 increases, thereby enabling the first torsion spring assembly 3 to prevent the socket cover 2 from detaching from the socket body 4, improving the reliability of the socket cover 2 covering the socket body 4. Furthermore, a retaining shaft 9 is installed on the shaft bracket 8. When the socket cover 2 covers the socket body 4, the locking bracket 5 abuts against the retaining shaft 9 under the torque of the second torsion spring assembly 7. In other words, During the process of the socket cover 2 covering the socket body 4, the torsion spring of the second torsion spring assembly 7 generates torque. Under the action of the torsion spring torque, the locking bracket 5 will abut against the locking shaft 9. When the socket cover 2 needs to be opened, the torque generated by the second torsion spring assembly 7 must be overcome to allow the locking bracket 5 to disengage from the locking shaft 9, further improving the reliability of the socket cover 2 covering the socket body 4. Therefore, even if the anti-detachment connector is subjected to vibration during transportation, it still needs to overcome the torque generated by the second torsion spring assembly 7 and the obstruction of the first torsion spring assembly 3 to separate the socket cover 2 from the socket body 4, thereby improving the reliability of the socket cover 2 and the socket body 4 during transportation. However, as the anti-detachment connector travels with the vehicle, under uneven and harsh road conditions, the anti-detachment connector is subjected to vibration, impact, and other harsh conditions during transportation, and there are still cases where the socket cover 2 and the socket body 4 separate, resulting in damage to the contact components inside the socket body 4 and affecting the insertion performance. Therefore, in this embodiment, a pull rod assembly 100 is installed on the side wall of the socket cover 2, such as Figure 3 and Figure 4As shown, the pull rod assembly 100 includes a bracket 101, a pull rod 103, and a spring 104. The bracket 101 is detachably mounted on the side wall of the socket cover 2. A positioning cylinder 102 is provided on the bracket 101. The positioning cylinder 102 has a stepped through hole, and the spring 104 is installed in the stepped through hole. A positioning sleeve 105 is provided at one end of the pull rod 103. The other end of the pull rod 103 passes through the spring 104 and exits through the small hole of the stepped through hole. A pull rod cap 106 is installed on the pull rod 103 that exits through the positioning cylinder 102. The diameter of the positioning sleeve 105 is smaller than the diameter of the large hole of the stepped through hole. A shallow groove 107 and a deep groove 108 are provided on the outer end face of the positioning cylinder 102. A positioning rod is radially provided on the pull rod 103. When the positioning rod is located in the deep groove 108, the positioning sleeve 105 is fitted onto the corresponding shaft. When the positioning rod is located in the shallow groove 107, the positioning sleeve 105 is fitted onto the corresponding shaft. 05. When the socket cover 2 covers the socket body 4, the locking bracket 5 abuts against the shaft under the torque of the second torsion spring assembly 7. At this time, the shaft and the pull rod 103 are coaxial, while the positioning rod is larger than the shallow groove 107. The spring 104 is compressed. Then, the operator only needs to pull it outward to disengage the positioning rod from the shallow groove 107. Then, rotate the pull rod cap 106 to rotate the positioning rod and align it with the deep groove 108. Then, the operator releases the pull rod cap 106. The positioning sleeve 105 moves axially under the elastic restoring force of the spring 104, and the end of the shaft enters the positioning sleeve 105. At this time, the relative positions of the socket cover 2 and the socket body 4 are relatively fixed. Therefore, during transportation, there is no need to worry about the socket cover 2 and the socket body 4 separating, ensuring the reliability of the anti-disengagement connector during transportation.
[0023] In this embodiment, the first torsion spring assembly 3 includes a first shaft and a first torsion spring. The first torsion spring is fitted onto the first shaft, and the first shaft is rotatably mounted on the mounting bracket 10. The socket cover 2 is rotatably mounted on the first shaft. After the first torsion spring is installed, when the socket cover 2 covers the socket body 4, the socket cover 2 is parallel to the mounting panel 1. At this time, the first torsion spring generates a certain torque, and the socket cover 2 is always in contact with the mounting panel 1 under the torque of the first torsion spring. When it is necessary to open the socket cover 2, the socket cover 2 needs to be flipped. At this time, the first torsion spring can generate a greater torque to prevent the socket cover 2 from flipping. Of course, when selecting the first torsion spring, the operator can overcome the torque of the first torsion spring and pry open the socket cover 2 to facilitate the insertion of the plug and socket.
[0024] In this embodiment, the second torsion spring assembly 7 includes a second shaft and a second torsion spring. The second shaft is rotatably mounted on the socket cover 2, and the second torsion spring is fitted onto the first shaft. The locking frame 5 is mounted on the second shaft and rotates synchronously with the second shaft. When the socket cover 2 covers the socket body 4, the locking frame 5 abuts against the shaft under the torque of the second torsion spring. Furthermore, the locking frame 5 has a slot 6 corresponding to the locking shaft. When the socket cover 2 covers the socket body 4, the locking shaft is located in the corresponding slot 6. Preferably, the slot 6 is an arc-shaped slot with an arc radius of 180°, and the entrance of the arc-shaped slot has an outwardly turned arc surface, which facilitates the shaft entering the slot 6.
[0025] In this embodiment, the retaining shaft includes a connecting section and two stepped columns. Both ends of the connecting section are provided with connecting holes. The shaft frame 8 is provided with a notch. The connecting section is located in the notch, and both ends of the connecting section are in contact with the inner sidewall of the notch. The stepped columns are respectively inserted into the shaft frame 8 and connected to the connecting section. The larger end of the stepped column is located on the outside of the shaft frame 8. Furthermore, the connecting section and the stepped column can be detachably connected by threads. When the retaining shaft is in the shaft frame 8, it can be ensured that the length of the retaining shaft located on the outside of the shaft frame 8 is consistent. In this embodiment, the second shaft has two locking brackets 5. The locking brackets 5 and the second shaft can be connected by a key. When the socket cover 2 covers the socket body 4, the locking brackets 5 abut against the corresponding second shaft located on the outside of the shaft frame 8.
[0026] In this embodiment, the pull rod cap 106 is provided with anti-slip texture, which facilitates the gripping and rotation of the pull rod cap 106, thereby facilitating the switching of the positioning rod back and forth within the shallow groove 107 and the deep groove 108. Furthermore, the included angle between the shallow groove 107 and the deep groove 108 is 90°, thereby forming a cross-shaped groove between the shallow groove 107 and the deep groove 108. Therefore, the operator only needs to rotate 90° to switch back and forth within the shallow groove 107 and the deep groove 108.
[0027] In this embodiment, a sealing gasket is installed on the socket cover 2 to seal the end face of the socket body 4. The sealing gasket can ensure the sealing performance between the socket cover 2 and the socket body 4, thereby preventing dust and other impurities from entering the socket body 4 during transportation, which would affect the reliability of the anti-disconnect connector.
[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
