[0041] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention.
[0042] It should be noted that, for the convenience of description, the end where the tail cover 7 is located is defined as the rear end, and the end away from the tail cover 7 is defined as the front end.
[0043] Please refer to the through-hole connector provided by the utility model Figure 2-4 The through-hole connector includes a cable 4, a shielding sleeve 3 and an outer shell 5. The shielding sleeve 3 is cylindrical as a whole. The shielding sleeve 3 and the cable 4 inserted therein are fixedly connected. The shielding sleeve 3 and the outer shell 5 cooperate with each other to prevent the shielding sleeve 3 from moving axially (referred to as "anti-channeling") and / or rotating radially (referred to as "anti-rotation"), thereby preventing the cable 4 fixedly connected to the shielding sleeve 3 from moving axially and / or rotating radially, so that the through-hole connector has a locking function for the wiring harness, thereby improving the assembly efficiency and convenience of the cable 4 at the device end.
[0044] Please refer to Figure 5-6 The outer shell 5 includes a fixed flange portion 502 installed on the mounting plate of the device, and at least one threading hole formed by extending axially forward and backward from the fixed flange portion 502, and the threading hole includes a plug-in portion 501 extending forward from the fixed flange portion 502 and a protective portion 503 extending backward from the fixed flange portion 502.

[0046] It should be explained that the setting form of the flange 3-1 at the front end of the shielding sleeve 3 and the setting form of the groove 5-1 at the front end of the plug-in part 501 are not limited, as long as they can prevent the shielding sleeve 3 from moving backward and / or rotating relative to the outer shell 5.

At this time, the flange 3-1 cooperates with the groove 5-1 to simultaneously achieve the functions of preventing the cable 4 from moving backward and rotating backward. However, if the groove 5-1 at the front end of the plug-in part 501 is set in a full circle, no matter whether the flange 3-1 is set in a plurality of intervals or in a full circle, it can only achieve the function of preventing the cable 4 from moving backward, but cannot achieve the function of preventing rotation.

[0048] It should be noted that the arrangement form of the rear end flange 3-2 of the shielding sleeve 3 and the arrangement form of the protrusion 5-2 on the inner wall of the protection part 503 are not limited, as long as the shielding sleeve 3 can be prevented from moving forward relative to the outer shell 5. Specifically, the number of the rear end flange 3-2 of the shielding sleeve 3 is at least one, and the protrusion 5-2 on the inner wall of the protection part 503 can be at least one, or can be arranged in a whole circle. When the rear end flange 3-2 of the shielding sleeve 3 can also be arranged in a whole circle, the protrusion 5-2 on the inner wall of the protection part 503 can be at least one, or can be arranged in a whole circle.
[0049] As another specific solution of the utility model, the front end of the plug-in portion 501 is provided with a groove 5-1 that matches with the flange 3-1, and the flange 3-1 and the groove 5-1 cooperate to prevent the shielding sleeve 3 from moving backward or rotating relative to the outer shell 5. The inner wall of the protection portion 503 is provided with a protrusion 5-2 that is inclined from front to back toward the axis direction of the outer shell 5 and matches with the flange 3-2, and the flange 3-2 and the protrusion 5-2 cooperate to prevent the shielding sleeve 3 from moving forward relative to the outer shell 5.
[0050] Please refer to Figure 8 The shielding sleeve 3 includes a large diameter section 301 arranged at the front section and matched with the shielding ring 2, and a small diameter section 302 arranged at the middle and rear section and matched with the cable 4, and a circular arc transition is formed between the small diameter section 302 and the large diameter section 301.

[0051] Of course, the anti-slip and anti-rotation functions of the cable in the connector can also be achieved in the following manner: the front end of the shielding sleeve 3 is provided with at least one flange 3-1 extending outward in a direction away from the center line of the shielding sleeve 3; the inner wall of the plug-in portion 501 is provided with at least one groove 5-1 that matches the flange 3-1, and the flange 3-1 matches the groove 5-1 to prevent the shielding sleeve 3 from moving axially and rotating radially relative to the outer shell 5. It should be noted that at this time, the shielding sleeve 3 and the outer shell 5 are installed in a forced manner, and the flange on the shielding sleeve 3 is forced into the groove 5-1 on the outer shell 5.
[0052] The shielding sleeve 3 and the cable 4 are fixedly connected, such as by crimping, friction welding, ultrasonic welding, etc.
[0053] Preferably, the rear end face of the protrusion 5-2 is a step surface. This design has the following advantages: on the one hand, it can ensure that the flange 3-2 on the shielding sleeve 3 cooperates with the step surface after being installed in place, and the inner wall of the threading hole on the outer shell 5 will not be scratched during disassembly; on the other hand, after the cable 4 is assembled to the product, a disassembly tool is used to cooperate with the step surface to facilitate the disassembly of the cable 4.
[0054] Specifically, the via connector further comprises a front cover 1, a shielding ring 2, a wire sealing body 6 and a rear cover 7, the specific structure of which belongs to the prior art and will not be described in detail in the present utility model.

At this time, the shielding sleeve 3 and the outer shell 5 have anti-rotation and anti-slip structures, and then the front cover 1, the wire sealing body 6 and the rear cover 7 are assembled on the outer shell 5 in sequence, and the assembly is completed.
[0056] It should be noted that the through-hole connector in the present invention can be either a single-core through-hole connector or a multi-core multi-hole connector. When it is a multi-core through-hole connector, a plurality of threading holes are provided on the outer shell 5, and the plurality of threading holes are arranged side by side along the width direction of the fixed flange portion 502. The through-hole connector includes a plurality of shielding sleeves 3, and the shielding sleeves 3 are installed in each threading hole one by one, and a plurality of cables 4 can be installed in each shielding sleeve 3 one by one.
