[0001] This utility model belongs to the technical field of plug auxiliary tools, specifically relating to a shielded front plug anti-misinsertion and unplugging device. Background Technology

[0002] In the field of electronic device connections, shielded front plugs are widely used due to their excellent electromagnetic shielding performance and stable signal transmission characteristics. However, in practical use, the insertion and removal of shielded front plugs often carries the risk of misoperation, especially in complex or crowded electronic device environments. Misoperation can not only lead to unstable device connections and affect signal transmission quality, but may also damage the plug and device interface, increasing maintenance costs. Therefore, this application proposes a device to prevent misoperation of shielded front plugs. Utility Model Content

[0003] The purpose of this invention is to provide a shielded front plug anti-misinsertion device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a shielded front plug anti-misinsertion device, comprising a connecting plate, a limiting sleeve inside the connecting plate, an insertion hole inside the limiting sleeve, a connecting frame fixedly connected to the front of the connecting plate above the limiting sleeve, two "C"-shaped connecting elastic members symmetrically fixedly connected inside the connecting frame, a limiting arc member fixedly connected to the bottom end of the two connecting elastic members, a plurality of limiting protrusions evenly distributed on the concave surface of the limiting arc member, and an installation sleeve fitted on the outside of the limiting sleeve.

[0005] In a preferred embodiment, the top of the limiting sleeve has a cavity for limiting the movement of the arc-shaped component, and the outer surface of the limiting arc-shaped component has a guide surface.

Detailed Implementation

[0018] The present invention will be further described below with reference to the embodiments.

[0019] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0020] Please see Figure 1-3This utility model provides a shielded front plug anti-misinsertion device, including a connecting plate 1. A limiting sleeve 104 is provided inside the connecting plate 1, and an insertion hole 103 is opened inside the limiting sleeve 104. A connecting frame 102 is fixedly connected to the front of the connecting plate 1 above the limiting sleeve 104. Two "C"-shaped connecting elastic members 107 are symmetrically fixedly connected inside the connecting frame 102. A limiting arc-shaped member 105 is fixedly connected to the bottom end of the two connecting elastic members 107. The limiting arc-shaped member 105 has a recess... Multiple limiting protrusions 106 are evenly distributed on the surface. An installation sleeve 2 is fitted over the limiting sleeve 104. A cavity for the movement of the limiting arc-shaped component 105 is opened at the top of the limiting sleeve 104. A guide surface is opened on the outward-facing side of the limiting arc-shaped component 105. A weakening groove is opened on one side of the connecting elastic component 107. A first limiting groove 1041 is opened at the bottom of the limiting sleeve 104. A second limiting groove 202 is opened at the bottom of the installation sleeve 2. Installation holes 101 are opened at each of the four corners of the connecting plate 1. The connecting frame 1... The surface of 02 is equipped with magnets. As the main part of the device, the connecting plate 1 is responsible for connecting and supporting other components. The connecting plate 1 is fixed in the required position through the mounting hole 101 to ensure the stability of the entire device. The limiting sleeve 104 is located inside the connecting plate 1 and is used to limit the insertion position of the plug. The plug enters the limiting sleeve 104 through the insertion hole 103 and is constrained by the limiting sleeve 104. The insertion hole 103 is located inside the limiting sleeve 104 and is the channel for plug insertion. The plug is inserted by aligning it with the insertion hole 103 and connecting to the internal circuit of the device. The connecting frame 102 is fixed on the front of the connecting plate 1 and is used to install the connecting elastic element 107 and the limiting arc element 105. The connecting frame 102 provides support and fixing points for the connecting elastic element 107 and the limiting arc element 105. The connecting elastic element 107 is "C" shaped and is connected between the connecting frame 102 and the limiting arc element 105 to provide elastic support. When the plug is inserted, the connecting elastic element 107 is squeezed and deformed to provide the elastic force required for plug insertion. The weakening groove on one side facilitates easier deformation and is connected to the connecting elastic member 107. It has a concave surface and a limiting protrusion 106 to limit the insertion and removal of the plug. When the plug is inserted, the concave surface of the limiting arc member 105 fits against the outer contour of the plug, and the limiting protrusion 106 prevents the plug from being accidentally pulled out.The guide surface facilitates smooth plug insertion. Located on the limiting arc member 105, the guide surface guides the plug insertion, allowing it to proceed smoothly without obstruction. The weakening groove (located on the connecting elastic member 107) reduces the strength of the connecting elastic member 107, making it more prone to deformation. When the plug is inserted, the weakening groove makes the connecting elastic member 107 easier to compress, providing more insertion space for the plug. The cooperation between the limiting arc member 105 and the connecting elastic member 107 effectively prevents accidental plug insertion and removal, reducing the risk of equipment damage or data loss due to misoperation. The design of the guide surface and weakening groove makes plug insertion smoother and reduces operational difficulty. By preventing accidental insertion and removal and ensuring a secure connection, this device improves the safety and reliability of the equipment, ensuring normal operation and secure data transmission.

[0021] The mounting sleeve 2 and the limiting sleeve 104 have a mating protrusion 201 on their mating surfaces. The limiting sleeve 104 has a mating groove 1042 that matches the mating protrusion 201. The mating protrusion 201 has an clearance groove 203 inside. The mounting sleeve 2 is fitted over the limiting sleeve 104 to further fix the plug. The mounting sleeve 2 and the limiting sleeve 104 are tightly fitted together and fixed by the mating protrusion 201 and the mating groove 1042. The mating protrusion 201 and the mating groove 1042 are located on the mounting sleeve 2 and the limiting sleeve 104, respectively, to achieve a tight fit between the two. The mating protrusion 201 is inserted into the mating groove 1042 and a stable connection is achieved by locking them together. The clearance groove 203 ensures that the plug is not obstructed when inserted. The clearance groove 203 (located inside the mating protrusion 201) ensures that the plug is not obstructed when inserted and can smoothly enter the device. The first limiting groove 1041 and the second limiting groove 202 are located at the bottom of the limiting sleeve 104 and the mounting sleeve 2, respectively, to further limit the insertion and removal of the plug. After the plug is inserted, its bottom is constrained by the first limiting groove 1041 and the second limiting groove 202 to prevent it from being accidentally pulled out. The tight fit between the mounting sleeve 2 and the limiting sleeve 104, as well as the constraining effect of the first limiting groove 1041 and the second limiting groove 202, ensures a stable connection between the plug and the device.

[0022] The working principle and usage process of this utility model are as follows: First, when the plug is inserted, it smoothly enters the insertion hole 103 along the guide surface (located on the limiting arc member 105). At this time, the concave surface of the limiting arc member 105 fits against the outer contour of the plug, while the limiting protrusion 106 contacts the surface of the plug and generates friction. Simultaneously, the connecting elastic member 107 is compressed and deformed (affected by the weakening groove), providing the elastic force required for the plug insertion. After the plug is fully inserted, its bottom is constrained by the first limiting groove 1041 and the second limiting groove 202, further preventing accidental removal. In addition, the mounting sleeve 2 and the limiting sleeve 104 are tightly fitted through the mating protrusion 201 and the mating groove 1042, increasing the stability of the device.
