[0030] refer to Figures 1-7 A rotary lock type power adapter wiring structure includes: a plastic housing 1, an end cap 2 fixed to the lower side of the plastic housing 1, a wire 3 connected to one side of the plastic housing 1, a reserved opening 4 opened on one side of the plastic housing 1, a wiring structure 5 provided on the inner side of the plastic housing 1, and a circular groove 6 opened on one side of the plastic housing 1;

[0031] The wiring structure 5 includes a fixed base plate 51. The fixed base plate 51 is fixed to the inner side of the plastic housing 1. Several groups of compression springs 52 are fixed to the fixed base plate 51. A connecting block 53 is fixed to one side of the several groups of compression springs 52. A locking claw 54 is fixed to one side of the connecting block 53. A handle 55 is fixed to one side of the locking claw 54. The fixed base plate 51 is provided with an internal thread 56.

[0032] An external thread 7 is formed on one side of the wire 3 .

[0033] A handle 55 is attached to the outer side wall of the reserved opening 4 .

[0034] The user holds the handle 55 with his hand and pulls it outward, since the handle 55 is fixedly connected with the locking claw 54, this action will drive the locking claw 54 to move outward together, and then compress the compression spring 52 between the connecting block 53 and the fixed base plate 51. The compression of the compression spring 52 provides the locking claw 54 with a resetting force inward, but at this time, since the handle 55 is held and pulled outward, the locking claw 54 remains in the outwardly extended state. Next, the user inserts one end of the wire 3 (the part with the external thread 7) into the circular groove 6, and the outer side wall of the reserved port 4 is fitted with the handle 55 to prevent the handle 55 from deviating from the predetermined path.

[0035] The connecting block 53 is in contact with the fixed base plate 51 and the plastic shell 1.

[0036] The contact design between the connecting block 53 and the fixed base plate 51 and the plastic shell 1, and the close contact between the locking claw 54 and the wire 3, further enhance the stability and reliability of the connection.

[0037] The inner side wall of the locking claw 54 is in contact with the wire 3.

[0038] The inner side wall of the locking claw 54 is in close contact with the outer side wall of the wire 3, and this threaded connection is not only firm and reliable, but also effectively prevents the wire 3 from accidentally falling off during use.

[0039] The external thread 7 is in threaded connection with the internal thread 56.

[0040] The compression spring 52 is arranged in a rectangular array at equal distances.

[0041] The rectangular array of the compression spring 52 ensures the uniformity and consistency of the locking claw 54 during resetting, thereby improving the overall performance and durability of the entire wiring structure 5.

[0042] Working principle: please refer to Figures 1-7 As shown, first, the working principle is as follows:

[0043] First, when the wire 3 needs to be connected to the wiring structure 5 in the plastic shell 1, the user holds the handle 55 with his hand and pulls it outward, since the handle 55 is fixedly connected with the locking claw 54, this action will drive the locking claw 54 to move outward together, and then compress the compression spring 52 between the connecting block 53 and the fixed base plate 51. The compression of the compression spring 52 provides the locking claw 54 with a resetting force inward, but at this time, since the handle 55 is held and pulled outward, the locking claw 54 remains in the outwardly extended state. Next, the user inserts one end of the wire 3 (the part with the external thread 7) into the circular groove 6, and the outer side wall of the reserved port 4 is fitted with the handle 55 to prevent the handle 55 from deviating from the predetermined path.

[0044] When the outer thread 7 part of the wire 3 is completely entered into the inside of the plastic shell 1, and is threadedly connected with the inner thread 56 on the fixed base plate 51, the user can loosen the handle 55, at this time, the compression spring 52 releases the elastic potential energy stored in it, pushes the connecting block 53 and the locking claw 54 to move inward, the inner side wall of the locking claw 54 is closely attached to the outer side wall of the wire 3, and at the same time, such thread connection is not only firm and reliable, but also can effectively prevent the wire 3 from accidentally falling off during use, in addition, the close contact design between the connecting block 53 and the fixed base plate 51, the plastic shell 1, and the close contact of the locking claw 54 and the wire 3, further enhances the stability and reliability of the connection. At the same time, the rectangular array of the compression spring 52 is equidistantly arranged, which ensures the uniformity and consistency of the locking claw 54 in the resetting process, thereby improving the overall performance and durability of the whole wiring structure 5. The rotating locking type power adapter wiring structure 5 realizes the quick and firm connection of the wire 3 and the power adapter through the ingenious mechanical design and thread connection principle, and provides the user with convenient and reliable use experience.
