[0020] Referring to Figs holding the aforementioned insulation body 1 and limited holding the aforementioned wire coil 4; plural conductive terminal 2, held by the aforesaid insulation body 1 and exposed the aforementioned shielding shell 3, the aforementioned conductive terminal 2 corresponds to the aforementioned core wire one-to-one and electrically connected; Accordingly, the invention wire-end connector 100 enables the wire-end connector 4 to avoid the more cramped peripheral position of the board-end connector 200, thereby not interfering with the installation of the wire-end connector 100 on the board-end connector 200 , which is conducive to the smoothness of the wire-end connector 100 on the board-end connector 200 Docking ensures that the user can place the outward cable 4 in a limited space in an orderly and normal manner, improving the user experience; the aforementioned conductive terminal 2 corresponds to the aforementioned core one-to-one and is fixed by welding.

[0021] Please refer to Figures 4 and 5. The aforementioned axial direction defines the vertical direction. The aforementioned insulating body 1 includes a base 11 and a column 12 protruding upward from the base 11 along the aforementioned axial direction. The aforementioned shielding shell 3 includes a first shell 31 and a second shell 32. The first shell 31 and the second shell 32 are respectively installed on the upper and lower sides of the aforementioned insulating body 1 and are fastened to each other. The aforementioned first shell 31 includes a top wall 311 and a first annular side wall 312. The aforementioned second shell 32 includes a bottom wall 321 opposite to the aforementioned top wall 311 and a second annular side wall 322 that fastens to the aforementioned first annular side wall 312. Both the first housing 31 and the second housing 32 include annular sidewalls, which facilitates the smooth rotation of the shielding housing 3 relative to the insulating body 1 around the aforementioned axial direction. The first housing 31 and the second housing 32 are interlocked and fixed together, thus the shielding housing 3, composed of the first housing 31 and the second housing 32, rotates as a whole relative to the insulating body 1. After the first housing 31 and the second housing 32 are installed and interlocked from the upper and lower sides of the insulating body 1, the top wall 311 of the first housing 31 is located above the base 11, and the bottom wall 321 of the second housing 32 is located below the base 11. The first housing 31 and the second housing 32 limit the insulating body 1 along the aforementioned axial direction. Once the first housing 31 and the second housing 32 are interlocked, the shielding housing 3 has a rotatable connection to the insulating body 1 and will not easily separate. Unless the fastening action between the first housing 31 and the second housing 32 is released, the first housing 31 and the second housing 32 can be separated from the upper and lower sides of the insulating body 1.

[0022] Please continue to refer to Figures 4 and 5. The aforementioned second annular sidewall 322 is provided with two stepped portions 3220. The aforementioned insulating body 1 is provided with a boss portion 111 that can abut against the aforementioned stepped portions 3220 to restrict the aforementioned forward / reverse rotation. The aforementioned boss portion 111 abuts against one of the aforementioned stepped portions 3220 to stop the aforementioned shielding shell 3 from rotating forward relative to the aforementioned insulating body 1; the aforementioned boss portion 111 abuts against the other of the aforementioned stepped portions 3220 to stop the aforementioned shielding shell 3 from rotating backward relative to the aforementioned insulating body 1. Specifically, the present invention forms the two aforementioned stepped portions 3220 by partially cutting away the aforementioned second annular sidewall 322. The arc length of the cut portion accounts for about 1 / 2 of the entire aforementioned second annular sidewall 322, which limits the range of rotation and facilitates normal rotation and return to position. Therefore, when using this invention, the aforementioned wire connector 100 can be seamlessly connected and rotated smoothly by 180 degrees, ensuring that the user can arrange the outwardly protruding cable 4 in an orderly and normal manner in a limited space, thus improving the user experience.

[0023] Referring to FIG. Thus, it needs to be emphasized that during use, the aforementioned shielding shell 3 composed of the aforementioned first shell 31 and the aforementioned second shell 32, is rotated together as a whole with respect to the preceding insulation body 1 , there is no relative position rotation between the preceding first shell 31 and the aforesaid second shell 32 .

[0024] Referring to FIG 3 , the aforementioned limiting portion 323 has an opening toward the second half hole 3230 of the first shell 31 , the first half hole 3130 and the second half hole 3230 in conjunction to form a circular hole 30 for the wire coil 4 to be penetrated from the inside out. Accordingly, during use, the aforementioned masking shell 3 consisting of the aforementioned first shell 31 and the aforementioned second shell 32 is held by the aforementioned positioning portion 313 and the aforementioned limiting portion 323 jointly to the aforementioned wire coil 4, aforementioned The threading of the wire coil 4 from the aforementioned circular hole 30 will naturally be driven by the aforementioned shielding shell 3 , that is, the shielding shell 3 is capable of driving forward / reverse rotation of the wire coil 4 about the axial direction relative to the aforementioned insulation body 1 .

[0025] Referring to FIGS. The cover body 5 further includes a top plate 51 and an annular side plate 52 extending from the preceding top plate 51, both of which are capable of making contact with the first magnetic element 61 while limiting the first magnetic element 61 . The action of the aforementioned first magnetic element 61 is to be able to form a matching automatic positive conduction with the second magnetic element 62 in the plate-end connector 200 , adopting the principle of heteropolar magnetic attraction for automatic positive conduction and reliable fixed contact conduction. The action of the aforementioned cover plate 5 is that when the first magnetic element 61 limits the limiting space within the limit space formed by the aforementioned shielding shell 3 and the preceding insulation body 1 , the cover body 5 masks the preceding limit space to prevent the first magnetic element 61 from falling out of the preceding limit space. Therefore, the aforementioned lid body 5 can be understood as an anti-falling lid.

[0026] Referring to Figs. A barb 530 is provided on each of the preceding card legs 53 , and a plural perforation 110 is provided in the insulating body 1 , which extends in one-to-one correspondence within the preceding perforation 110 and by the preceding barbed 530 and the preceding perforation 11 The inner wall surface of 0 performs interference positioning, thereby fixing the aforementioned cover body 5 with the aforementioned insulation body 1 , that is, the aforementioned cover body 5 and the aforementioned conductive terminal 2 Thus, the cover body 5 is not rotating with respect to the insulation body 1 , which means that there is relative motion between the cover body 5 It is difficult to understand that the aforementioned cover body 5 and the aforementioned shielding shell 3 are separated from each other and are not fixed.

[0027] Referring to Figures 3, 4 and 7, 8, in the aforementioned shielding shell 3, the aforementioned bottom wall 321 is a non-porous plate-like, the aforementioned top wall 311 is an annular with a first opening 101 in the middle, the aforementioned lid body 5 is glued to the former first shielding shell 31 to form the inner wall surface of the aforementioned first opening 101. Specifically, the set of 6 of the first magnetic elements is located on the cylinder 12 and against the base 11 of the aforementioned, and, both the top plate 51 and the side plate 52 are in contact with the first magnetic element 6. Therefore, the first magnetic element 61 is held between the preceding insulating body 1 and the cover body 5 by limitation, preventing dropping. Because the aforementioned conductive terminal 2 is held and exposed by the preceding insulating body 1 and exposes the preceding shielding shell 3 , and as the preceding cover body 5 is a cover that prevents the detachment of the preceding first magnetic element 6 , the preceding cover body 5 is required to have an upper and lower pair with the preceding first opening 101 The corresponding second opening 102 , through which the preceding prism 12 passes through the preceding first opening 101 and the preceding second opening 102, enables the preceding conductive terminal 2 to be docked with the docking terminal 9 in the preceding plate end connector 200 by exposing the preceding prism 12 .

[0028] Referring to Figures 1 to 12, the present invention also relates to a connector assembly, which includes a wire-end connector 100 and a board-end connector 200 as described above. The aforementioned board-end connector 200 includes a circuit board 7, an insulating base 8, a mating terminal 9, and a mating housing 10. The aforementioned mating terminal 9 is held in place by the aforementioned insulating base 8, and the aforementioned mating housing 10 is fixed to the aforementioned circuit board 7 and covers the aforementioned insulating base 8. When the aforementioned wire-end connector 100 and the aforementioned board-end connector 200 are inserted, the aforementioned conductive terminal 2 can achieve electrical connection with the aforementioned mating terminal 9. Specifically, please refer to Figures 9 to 12.

That is, the aforementioned column 12 extends into the aforementioned receiving cavity 80 to achieve an electrical connection between the aforementioned conductive terminal 2 and the aforementioned docking terminal 9.

[0029] Please refer to Figures 10 and 12. The aforementioned wire-end connector 100 includes a first magnetic element 61, and the aforementioned board-end connector 200 includes a second magnetic element 62. The aforementioned second magnetic element 62 is magnetically attracted to the aforementioned first magnetic element 61. As mentioned above, the aforementioned first magnetic element 61 and the aforementioned second magnetic element 62 form a matching automatic alignment. Using the principle of opposite pole magnetic attraction, the aforementioned wire-end connector 100 and the aforementioned board-end connector 200 are automatically aligned, realizing reliable holding and contact between the aforementioned conductive terminal 2 and the aforementioned mating terminal 9.

[0030] Please refer to Figures 4 and 10.
