[0002] The double-pull retractable electrical connector has a self-locking device inside the reel of the reel box and has an automatic cable arrangement function. After pulling out a section of the cable, the self-locking device works (the power cord stops moving). If you want to retract the wire, you need to pull out a section of the power cord at the same time. The wire passes over the self-locking device to release the power cord, and the wire automatically retracts into the reel.

[0003] The existing double-pull telescopic electrical connector with a switch is mainly composed of a first shell, a second shell, a winding box, a switch shaft core and wires, and the first shell and the second shell are sleeved on the outside of the wires to protect the inside thereof. The existing first shell and the second shell are connected and installed by screws. When it is necessary to inspect and repair the components installed inside the first shell and the second shell, auxiliary tools (such as a screwdriver) are required to disassemble and separate the first shell and the second shell, which makes it inconvenient to disassemble and install the first shell and the second shell. In addition, when the wires slide, they directly contact the grooves of the first shell and the second shell, and friction will occur between the wires and the grooves, which can easily cause wear on the surface of the wires.

The magnetic component 701 and the iron component 706 in the magnetic connection state pre-connect the first shell 1 and the second shell 2.

[0027] Please refer to Figure 3 A winding box 6 is rotatably mounted inside the first housing 1 , a switch shaft core 3 is fixedly connected to the center of the winding box 6 , and an electric wire 4 is provided on the surface of the winding box 6 .

[0028] In this embodiment, the switch shaft core 3 is pressed by hand, which drives the winding box 6 to rotate, and the rotating winding box 6 can reel in or unreel the wire 4 .

[0029] Please refer to Figure 3 The roller 705 contacts the surface of the wire harness of the electric wire 4 and is used to protect the electric wire 4 .

[0030] In this embodiment: when the wire 4 is wound or unwound, since the roller 705 contacts the surface of the wire harness of the wire 4, when the wire 4 slides, the roller 705 cooperates with the second spring 707 to protect the wire 4, avoiding the wire 4 from directly contacting the grooves of the first shell 1 and the second shell 2 when sliding, which may easily cause wear.

[0031] Please refer to Figure 2 , the docking assembly 5 includes a groove 501, a first spring 502, a moving member 503, a button 504, a connecting shaft 505, a torsion spring 506 and a locking groove 507;

[0032] A groove 501 is provided on the outer side of the first shell 1 and the second shell 2, the first spring 502 is fixedly connected to the inside of the groove 501, the moving part 503 is fixedly connected to the end of the first spring 502, the connecting shaft 505 is formed at both ends of the button 504, and the connecting shaft 505 is rotatably connected to the moving part 503, the two ends of the torsion spring 506 are respectively engaged with the moving part 503 and the button 504, and the twisted torsion spring 506 is used to drive the button 504 to rotate and reset, and the lock slot 507 is provided inside the groove 501.

[0033] In this embodiment: the hand drags the button 504 and drives the moving part 503 to move in the direction close to the first shell 1, then the moving part 503 moving in the direction of the first shell 1 stretches the first spring 502 and moves the button 504 in the direction close to the locking groove 507, the hand presses the button 504 again, and the button 504 is rotated to an inclined state with the connecting shaft 505 as the center, and the torsion spring 506 is squeezed, so that the torsion spring 506 is twisted under force, and when the bent portion of the button 504 moves to a position aligned with the locking groove 507, the hand loosens the button 504, so that the twisted torsion spring 506 drives the button 504 to rotate and reset, and the bent portion of the button 504 in the reset state is inserted into the locking groove 507, and the locking groove 507 and the button 504 in the engaged state fix the first shell 1 and the second shell 2 in the pre-connected state.

[0034] Please refer to Figure 2 The moving member 503 in the moving state toward the first housing 1 is used to stretch the first spring 502 , and the first spring 502 in the reset state is used to drive the moving member 503 to move toward the second housing 2 .

[0035] In this embodiment, the moving member 503 is driven to move toward the first housing 1 , and the moving member 503 moving toward the first housing 1 stretches the first spring 502 and moves the button 504 toward the locking slot 507 .

[0036] Please refer to Figure 2 The locking groove 507 is used for inserting the bent portion of the button 504 therein, and the locking groove 507 and the button 504 in the engaged state are used to fix the first shell 1 and the second shell 2 in the pre-connected state.

[0037] In this embodiment: when the bent portion of the button 504 moves to a position aligned with the lock slot 507, the button 504 is loosened by the hand, so that the twisted torsion spring 506 drives the button 504 to rotate and reset, and the bent portion of the button 504 in the reset state is inserted into the lock slot 507.

[0038] Working principle: When the first shell 1 and the second shell 2 need to be docked and installed, first align the first shell 1 and the second shell 2, then insert the magnetic member 701 into the slot 702, so that the magnetic member 701 and the iron member 706 are magnetically connected. The magnetic member 701 and the iron member 706 in the magnetic connection state pre-connect the first shell 1 and the second shell 2. At this time, the hand drags the button 504 and drives the moving member 503 to move in the direction close to the first shell 1. The moving member 503 in the moving state toward the first shell 1 stretches the first spring 502 and moves the button 504 in the direction close to the lock slot 507. The hand presses the button 504 again. 04, rotate the button 504 to an inclined state with the connecting shaft 505 as the center, and squeeze the torsion spring 506, so that the torsion spring 506 is twisted by force. When the bent portion of the button 504 moves to a position aligned with the lock groove 507, loosen the button 504 by hand, so that the twisted torsion spring 506 drives the button 504 to rotate and reset. The bent portion of the button 504 in the reset state is inserted into the lock groove 507, and the engaged lock groove 507 and the button 504 fix the pre-connected first shell 1 and the second shell 2. Therefore, the above structure facilitates the disassembly and installation of the first shell 1 and the second shell 2, and further facilitates the maintenance of the double-pull telescopic electrical connector.

[0039] When the wire 4 is wound or unwound, the roller 705 contacts the surface of the wire harness of the wire 4, so that when the wire 4 slides, the roller 705 cooperates with the second spring 707 to protect the wire 4, thereby preventing the wire 4 from directly contacting the grooves of the first shell 1 and the second shell 2 when sliding, which may easily cause wear.
