DETAILED DESCRIPTION

[0021] The embodiments described below are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 as well as Figure 2 This embodiment provides a straight-plug locking connector, including a female connector 1 and a male connector 2 plug-connected to the female connector 1.

[0023] Specifically, the female socket connector 1 includes a female socket connector body 11, an outer terminal 12, and an inner terminal 13. One end of the connector body is provided with an opening 14 and extends towards the opposite end to form a receiving cavity 15. The outer terminal 12 is arranged in the receiving cavity 15, and the inner terminal 13 is arranged inside the outer terminal 12. A rotating groove 16 is provided on the inner side of the top of the outer terminal 12. The rotating groove 16 is an annular groove recessed from the inner side wall of the outer terminal 12 towards the outer side wall. The rotating groove 16 is provided with a pair of opposite insertion openings 17 connected to the opening 14 for the positioning pins 24 to be inserted. A pair of opposite telescopic components 19 are arranged in the rotating groove 16. The telescopic component 19 includes a fixed seat 191, a telescopic shaft 192, a pressing block 193, and a damping spring 194. The fixed seat 191 is arranged on the side wall of the rotating groove 16. One end of the fixed seat 191 away from the side wall of the rotating groove 16 is provided with the telescopic shaft 192. The other end of the telescopic shaft 192 is connected with the pressing block 193. The damping spring 194 is sleeved outside the telescopic shaft 192. One end of the telescopic shaft 192 is connected with the fixed seat 191, and the other end of the telescopic shaft 192 is connected with the pressing block 193;

[0024] Specifically, the male socket connector 2 includes a connector terminal 21, a first sleeve 22, and a second sleeve 23. One end of the first sleeve 22 is connected with the connector terminal 21, and the other end of the first sleeve 22 is connected with the second sleeve 23. A pair of opposite positioning pins 24 are arranged on the outer wall of the connector terminal 21.

[0025] It should be noted that when the male connector 2 of the present application is connected to the female connector 1, the connector terminal 21 of the male connector 2 is aligned with the receiving cavity 15 at one end of the opening 14 of the female connector 1, and at the same time, it is ensured that the positioning pin 24 on the male connector 2 is aligned with a pair of insertion openings 17 on the outer terminal 12 of the female connector 1. Then, gently push the male connector 2 downward into the receiving cavity 15 of the female connector 1 until the positioning pin 24 is inserted into the insertion opening 17. At this time, due to the guidance of the insertion opening 17, the male connector 2 begins to enter the interior of the female connector 1, and at the same time, the pressing block 193 of the telescopic assembly 19 will abut against the side wall of the connector terminal 21 to provide a pressing force. After the male connector 2 is initially inserted in place, rotate the male connector 2 in the clockwise (or counterclockwise, depending on the design) direction. As the male connector 2 rotates, the positioning pin 24 gradually enters the rotation groove 16 after entering from the insertion opening 17 and is pressed by the pressing block 193 in the telescopic assembly 19. At this time, the connection between the male connector 2 and the female connector 1 is completed, realizing a stable electrical connection and mechanical locking. When it is necessary to separate the connected male connector 2 and female connector 1, rotate the male connector 2. When the positioning pin 24 of the male connector 2 is rotated to the insertion opening 17, pull the male connector 2 upward to separate the male connector 2 from the female connector 1.

[0026] Preferably, a square mounting plate 18 is provided on the outer side of one end of the opening 14 of the female connector body 11. One end of the mounting plate 18 is hinged with a connector cover 20, and the other end of the mounting plate 18 is detachably connected to the other end of the connector cover 20. Preferably, a mounting hole 10 is provided at each of the four corners of the mounting plate 18. When installing the female connector 1, align the mounting holes 10 at the mounting position through the mounting holes 10 and screw in the screws to fix the installation of the female connector 1. The setting of the connector cover 20 enables the opening 14 of the receiving cavity 15 to be shielded when the female connector 1 is not in use, playing a role in dust and water protection.

[0027] Preferably, the mounting plate 18 and the cover of the female connector 1 are rotatably connected by a rotating shaft 35, and a spring is provided outside the rotating shaft 35. One end of the spring is connected to the mounting plate 18, and the other end of the spring is connected to the female connector body 11. When the connector is not in use, the connector cover 20 can automatically cover the opening 14 of the receiving cavity 15 under the action of the spring. Specifically, the function of the spring is to provide a restoring force, so that the connector cover 20 can automatically close after use and maintain the sealing and dust-proof properties of the connector.

[0028] Preferably, a hook 31 and a first locking hole 32 are provided at one end of the connector cover 20 away from the rotating shaft 35, and a clamping groove 33 and a second locking hole 34 which cooperate with the hook 31 and the first locking hole 32 are provided on the mounting plate 18. The cooperation between the hook 31 and the clamping groove 33 can preliminarily fix the connector cover 20 and the connector body, and the arrangement of the first locking hole 32 and the second locking hole 34 enables a lock to be inserted to fix the connector cover 20 and the connector body.

[0029] Preferably, a metal sleeve cap 36 is provided at the bottom of the inner terminal 13, and a return spring is sleeved outside the metal sleeve cap 36. The bottom of the return spring abuts against the outer terminal 12. When the male connector 2 is inserted into the female connector 1, first the return spring is compressed. When the male connector 2 rotates by a certain angle, then the return spring provides an upward extrusion force, so that the positioning pin 24 abuts in the positioning hole, thereby enabling the male plug and the connector to be firmly connected.

[0030] Preferably, an annular accommodation groove 37 is annularly provided on one side of the mounting plate 18 close to the connector cover 20, and an annular rubber ring 38 is provided in the annular accommodation groove 37. The center of the annular rubber ring 38 coincides with the center of the opening 14 of the accommodation cavity 15. The arrangement of the annular rubber ring 38 can effectively prevent impurities such as external dust and water vapor from entering the connector, thereby protecting the normal operation of the internal components of the connector.

[0031] Preferably, a through hole is provided through the middle of the side of the female connector body 11, and a micro switch is connected to the through hole. When the male connector 2 is connected to the female connector 1, the micro switch is connected to the male connector 2, thereby starting the power supply by giving a signal to the connector.

[0032] Preferably, the pressing block 193 is a spherical pressing block 193 or a cuboid pressing block 193 with a chamfer at the top. The spherical pressing block 193 or the cuboid pressing block 193 with a chamfer can make the connector terminal 21 inserted more smoothly, reduce the jamming phenomenon caused by improper operation or the fitting clearance between components, thereby simplifying the connection operation process and improving the connection efficiency.

[0033] Preferably, the normal length of the telescopic assembly 19 is slightly greater than the depth of the rotating groove 16. The telescopic assembly 19 is in a certain compressed state, which can provide an extrusion force for the connector terminal 21, so that the connection between the female connector 1 and the male connector 2 is tighter.

[0034] Preferably, a scale mark is provided at the position of the male connector 2 corresponding to the positioning pin 24 to facilitate the alignment of the positioning pin 24 with the insertion port 17.

[0035] The utility model provides a straight-plug locking connector, comprising a female connector 1 and a male connector 2, which is inserted into the plug-in port 17 of the female connector 1 through the positioning pin 24 of the male connector 2, and rotated into the rotating groove 16, and combined with the telescopic component 19 to abut against the side wall of the connector terminal 21, so as to achieve a firm lock between the male connector 2 and the female connector 1. In this way, not only the stability of the connection between the male connector 2 and the female connector 1 is enhanced, but also the loosening of the connector connection caused by long-term use or external force is effectively prevented, thereby significantly improving the safety and reliability of the connection. At the same time, the design of the telescopic component 19 ensures that even if the male connector 2 is not fully rotated into place after insertion, it can provide a certain resistance to prevent the male connector 2 from accidentally coming out, simplifying the connection process and reducing the risk of operating errors. Therefore, the straight-plug locking connector has good connection stability and safety of use, thereby ensuring the service life of the connector and the safety of personnel.

[0036] The above disclosures are only several preferred embodiments of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
