DETAILED DESCRIPTION

[0021] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] See also Figures 1 to 5 As shown, an electrical connector includes a first joint 1 and a second joint 2, wherein the connecting ends of the first joint 1 and the second joint 2 are provided with a tightening portion 3, the first joint 1 is provided with an inner tube 11, and a plug 22 is provided in the inner tube 11, and the second joint 2 is provided with a plug 21 that can be inserted into the inner tube 11, and a socket 12 is provided in the plug 21. By operating the tightening portion 3, the plug 21 on the second joint 2 is driven to move into the inner tube 11 on the first joint 1.

[0023] When it is necessary to connect the first connector 1 and the second connector 2 together, first, the staff inserts one end of the insert tube 21 provided on the second connector 2 into the inner tube 11 on the first connector 1, and then, by operating the tightening part 3, the insert tube 21 can automatically move toward the depth of the inner tube 11 in the inner tube 11. When the insert tube 21 moves to the specified position in the inner tube 11, the plug 22 in the insert tube 21 will be inserted into the socket 12 in the inner tube 11, so that the plug 22 in the second connector 2 can be easily inserted into the socket 12 in the first connector 1. Through the setting of the tightening part 3, the first connector 1 and the second connector 2 are more convenient during the docking process, and there is no need for the staff to dock the first connector 1 and the second connector 2 together with force, which reduces the force required for docking the first connector 1 and the second connector 2.

[0024] See also Figure 2 As shown, the tightening part 3 includes a movable tube 31 and a fixed tube 32; the movable tube 31 is sleeved on the outside of the inner tube 11, one end of the movable tube 31 is movably arranged with the first joint 1, and a first internal thread 311 is provided on the inner wall of the end of the movable tube 31 away from the first joint 1; the fixed tube 32 is sleeved on the outside of the insert tube 21, one end of the fixed tube 32 is fixedly connected with the second joint 2, and a first external thread 321 meshing with the first internal thread 311 is provided on the outer wall of the end of the fixed tube 32 away from the second joint 2.

[0025] When the insert tube 21 is just inserted into the inner tube 11, the fixed tube 32 outside the insert tube 21 will be located inside the movable tube 31. When the movable tube 31 is rotated, since the first internal thread 311 on the movable tube 31 and the first external thread 321 on the fixed tube 32 are meshed, when the movable tube 31 is rotated, the fixed tube 32 will be automatically driven to move toward the inside of the movable tube 31, thereby driving the insert tube 21 on the second joint 2 to move toward the inner tube 11 on the first joint 1. The torque generated by the cooperation between the movable tube 31 and the fixed tube 32 allows the second joint 2 to be easily docked with the first joint 1.

[0026] See also Figure 2 and Figure 4 As shown, an annular limiting groove 13 is provided on the first joint 1, and an annular limiting block 312 is provided at one end of the movable tube 31 close to the first joint 1. The side of the limiting block 312 away from the movable tube 31 is embedded in the limiting groove 13 provided on the first joint 1, and the limiting block 312 can rotate in the limiting groove 13.

[0027] Through the cooperation of the annular limiting groove 13 and the limiting block 312 , the movable tube 31 is restricted on the first joint 1 , so that when the movable tube 31 rotates, it will not be separated from the first joint 1 .

[0028] See also Figure 4 As shown, a plurality of equally spaced guide grooves 111 are formed on the inner wall of the inner tube 11 , and a plurality of guide strips 211 corresponding to the guide grooves 111 are disposed on the outside of the insertion tube 21 .

[0029] By providing a guide groove 111 in the inner tube 11, when the insertion tube 21 enters the inner tube 11, the guide strip 211 provided on the outside of the insertion tube 21 will be inserted into the corresponding guide groove 111 provided in the inner tube 11, so that when the movable tube 31 rotates, its fixed tube 32 will not rotate in the inner tube 11, thereby affecting the position deviation between the plug 22 in the movable tube 31 and the socket 12 in the inner tube 11. At the same time, when the fixed tube 32 does not rotate, the movable tube 31 can only drive the fixed tube 32 to move into the inner tube 11 when it rotates.

[0030] See also Figure 4 As shown, a first positioning block 121 which can be embedded in the guide groove 111 is disposed outside the socket 12 .

[0031] When the socket 12 is placed in the inner tube 11, the first positioning block 121 outside the socket 12 will slide in the corresponding guide groove 111 opened in the inner tube 11, thereby preventing the position of the socket 12 from deviating when entering the inner tube 11, thereby affecting the docking effect.

[0032] See also Figure 5 As shown, a positioning groove 212 is provided in the insert tube 21 , and a second positioning block 221 corresponding to the positioning groove 212 is provided outside the plug 22 .

[0033] By providing a positioning groove 212 in the insertion tube 21 and cooperating with a second positioning block 221 provided outside the plug 22 , the position of the plug 22 will not deviate when the plug 22 enters the insertion tube 21 .

[0034] See also Figure 1 As shown, an end of the first connector 1 away from the second connector 2 is provided with an electric wire 4 electrically connected to the socket 12 , and a locking portion 5 is provided between the first connector 1 and the electric wire 4 .

[0035] When one end of the wire 4 passes through the first connector 1 and is connected to the socket 12 in the first connector 1, the wire 4 is temporarily fixed to the first connector 1 by the locking portion 5, thereby preventing the wire 4 from detaching from the first connector 1 and making the connection between the wire 4 and the socket 12 more secure.

[0036] See also Figure 3 As shown, the locking portion 5 includes a fixed sleeve 51, a locking tube 52 and a locking screw 53; the fixed sleeve 51 is sleeved on the end of the first joint 1 away from the second joint 2, one end of the fixed sleeve 51 is fixed to the first joint 1 by the locking screw 53, a second external thread 511 is provided on the outside of the end of the fixed sleeve 51 away from the first joint 1, and a plurality of equidistantly arranged elastic claws 512 are provided on the end of the fixed sleeve 51 away from the first joint 1; the locking tube 52 is sleeved on the outside of the fixed sleeve 51, and a second internal thread 521 is provided on the inner wall of the locking tube 52 to engage with the second external thread 511 provided on the outside of the fixed sleeve 51.

[0037] By setting the locking screw 53, one end of the fixed sleeve 51 can be temporarily fixed on the first connector 1. When the wire 4 is connected to the socket 12 in the first connector 1, by rotating the locking tube 52 outside the fixed sleeve 51, the second internal thread 521 provided on the inner wall of the locking tube 52 is meshed with the second external thread 511 provided on the outside of the fixed sleeve 51. When the locking tube 52 is rotated, the locking tube 52 will move toward the end of the fixed sleeve 51 away from the first connector 1, thereby squeezing the multiple elastic claws 512 on the fixed sleeve 51, so that the multiple elastic claws 512 on the fixed sleeve 51 are tightly fitted together with the outside of the wire 4, thereby fixing the wire 4, so that the wire 4 is fixed to the first connector 1.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
