[0035] Reference Figure 1 As shown, a shielding device for a connector 110 of an embodiment of the utility model includes an end 100, a shielding assembly 200 and a sleeve 300. The end 100 is used to cooperate with an external terminal for connection. A positioning platform 120 is provided on one side of the end 100. The positioning platform 120 is provided with a connector 110. The connector 110 is used to connect cables.

[0036] It should be noted that the connector 110 can be plug-fitted, snap-fitted, glued or integrally formed with the positioning platform 120. There is no specific limitation on the connection structure between the connector 110 and the positioning platform 120, as long as the terminal 100 can electrically connect the connector 110 to the external terminal.

[0037] Reference Figure 2 As shown, it can be understood that the shielding assembly 200 includes a shielding net 210, a lower shielding cover 220 and an upper shielding cover 230 that can rotate relative to the lower shielding cover 220. The shielding net 210 is made of insulating material and is arranged on the plastic shell outside the cable close to one end of the connector 110. The shielding net 210 is arranged around the cable.

[0038] Among them, the upper shielding cover 230 and the lower shielding cover 220 are respectively located on both sides of the connector 110, and the upper shielding cover 230 and the pressure rod 111 of the connector 110 are located on the same side of the connector 110 to ensure that the user can rotate the upper shielding cover 230 and the pressure rod 111 in sequence to install the cable. The upper shielding cover 230 and the lower shielding cover 220 are both connected to the positioning platform 120 of the terminal 100.

[0039] Specifically, the terminal 100 is provided with a mounting groove, and a mounting ring 221 is connected to the same side of the upper shielding cover 230 and the lower shielding cover 220, that is, the upper shielding cover 230, the lower shielding cover 220 and the mounting ring 221 are thin shell parts formed by injection molding, and the mounting ring 221 is installed in the mounting groove through a one-way fixing spring piece 226 on the outer wall, so that the upper shielding cover 230 and the lower shielding cover 220 are both connected to the positioning platform 120 of the terminal 100, and the upper shielding cover 230 and the lower shielding cover 220 are matched with the shape of the connector 110. The upper shielding cover 230 is rotated to make the upper shielding cover 230 and the lower shielding cover 220 snap-fit ​​together. The snap-fitted upper shielding cover 230 and the lower shielding cover 220 can surround and cover the connector 110, and the sleeve 300 is sleeved on the snap-fitted upper shielding cover 230 and the lower shielding cover 220.

[0040] By providing the mounting ring 221, on the one hand, the user can install the mounting ring 221 into the mounting groove to automatically position and install the upper shielding cover 230 and the lower shielding cover 220 on the positioning platform 120, thereby improving the installation stability of the upper shielding cover 230 and the lower shielding cover 220, that is, the convenience of assembly; on the other hand, the mounting ring 221 can be connected to the upper shielding cover 230 through the elastic arm 222. Compared with the traditional hinge structure, both ends of the elastic arm 222 can be bent, while ensuring that the upper shielding cover 230 can rotate, the range of movement of the upper shielding cover 230 is increased and the upper shielding cover 230 can be quickly reset, which effectively improves the user experience.

[0041] In addition, the upper shielding cover 230 and the lower shielding cover 220 can also be connected to the positioning platform 120 and respectively engaged with the connector 110, thereby simplifying the structure of the upper shielding cover 230 and the lower shielding cover 220. The connection structure between the upper shielding cover 230, the lower shielding cover 220 and the terminal 100 is not specifically limited, as long as the upper shielding cover 230 can rotate and engage with the lower shielding cover 220 to surround and cover the connector 110.

[0042] Reference Figure 2 and Figure 3 As shown, it can be understood that the upper shielding cover 230 is symmetrically provided with a card block 231 arranged vertically downward on both sides, and the lower shielding cover 220 is provided with a third card slot 223 for the card block 231 to be inserted into the two sides. The upper shielding cover 230 and the lower shielding cover 220 are relatively fixed by the cooperation between the card block 231 and the third card slot 223. The lower shielding cover 220 is also provided with an unlocking spring piece 224 for unlocking the card block 231. Specifically, the unlocking spring piece 224 is located on one side of the third card slot 223. Pressing the unlocking block can press the card block 231 inserted into the third card slot 223, thereby unlocking the card block 231.

[0043] Reference Figure 1 and Figure 4 As shown, it can be understood that an overpressure prevention assembly 400 is provided between the upper shielding cover 230 and the lower shielding cover 220 , and the upper shielding cover 230 and the lower shielding cover 220 cooperate with each other through the overpressure prevention assembly 400 to form an annular first limiting portion 240 .

[0044] Specifically, an arc-shaped first mating portion 232 is provided at one end of the upper shielding cover 230 away from the end 100, and an arc-shaped second mating portion 225 is provided at one end of the lower shielding cover 220 away from the end 100. The overpressure protection assembly 400 includes an overpressure protection buckle 410 provided on the upper shielding cover 230 and a first card slot 420 provided on the lower shielding cover 220. The overpressure protection buckle 410 is located on the side of the card block 231 facing the first mating portion 232. The overpressure protection buckle 410 is accommodated in the first card slot 420 and is engaged with the lower shielding cover 220 below the first card slot 420.

[0045] The overpressure prevention buckle 410 passes through the first slot 420 and is engaged with the lower shielding cover 220 plate below the first slot 420, so that the relative position between the engaged lower shielding cover 220 and the upper shielding cover 230 remains stable, thereby avoiding the problems of matching errors, wrong installation, missing installation, etc. between the lower shielding cover 220 and the upper shielding cover 230, so that the arc-shaped first matching portion 232 and the arc-shaped second matching portion 225 are combined to form an annular first limiting portion 240. Since the overpressure prevention buckle 410 is closer to the first matching portion 232 than the block 231, the overpressure prevention buckle 410 cooperates with the first slot 420 to ensure the stability of the structure of the first matching portion 232. The overpressure prevention assembly 400 is set as the overpressure prevention buckle 410 and the first slot 420. While simplifying the structure of the overpressure prevention assembly 400, the overpressure prevention buckle 410 cooperates with the block 231 to effectively improve the structural consistency and connection stability of the lower shielding cover 220 and the upper shielding cover 230.

[0046] It should be added that, under normal circumstances, the volume of the lower shielding cover 220 is slightly larger than that of the upper shielding cover 230, so that when the user assembles the connector 110, the lower shielding cover 220 can quickly position and cover the connector 110, thereby improving the convenience of assembling the connector 110. At this time, the center angle of the second matching portion 225 on the lower shielding cover 220 is larger than the center angle of the first matching portion 232. In order to ensure a reasonable structure and avoid affecting the structural strength of the upper shielding cover 230, the first card slot 420 and the third card slot 223 need to be arranged on the lower shielding cover 220. When the center angle of the second matching portion 225 is equal to or slightly larger than the center angle of the first matching portion 232, the first card slot 420 and the third card slot 223 can also be arranged on the upper shielding cover 230, and the card block 231 and the anti-overpressure buckle 410 are correspondingly arranged on the lower shielding cover 220. This is specially explained here and will not be repeated hereafter.

[0047] Reference Figure 5 As shown, it can be understood that the anti-overpressure buckle 410 includes a connecting portion 411 and a buckle body 412, the two ends of the connecting portion 411 are respectively connected to the bottom end surface of the upper shielding cover 230 and the buckle body 412, and the buckle body 412 and the connecting portion 411 are transitioned by an arc surface. The buckle body 412 is provided with a second slot 413, and the connecting portion 411 is tilted so that the second slot 413 is snap-fitted with the lower shielding cover 220 below the first slot 420.

[0048] The connecting portion 411 is tilted. On the one hand, the tilted connecting portion 411 can play a guiding role, guiding the buckle body 412 to quickly align with the lower shielding cover 220 below the first slot 420, thereby improving the assembly efficiency of the connector 110; on the other hand, the tilted connecting portion 411 can make the lower shielding cover 220 below the first slot 420 enter the second slot 413, so that the buckle body 412 semi-surrounds the lower shielding cover 220 below the first slot 420, thereby limiting the upper shielding cover 230 in the vertical direction and the width direction of the upper shielding cover 230, effectively improving the structural stability of the first limiting portion 240.

[0049] Reference Figure 4 and Figure 6 As shown, it can be understood that the shielding net 210 folds back and expands from the plastic shell close to the connector 110 and covers the first limiting portion 240. An annular adapter 310 is provided in the sleeve 300, and the adapter 310 is provided with a second limiting portion, wherein the first limiting portion 240 is an annular inclined surface, and the outer diameter of the first limiting portion 240 gradually decreases along the axial direction of the sleeve 300 away from the end head 100, and the second limiting portion is an annular inclined surface arranged on the inner side of the adapter 310 and matching the first limiting portion 240, and the second limiting portion cooperates with the first limiting portion 240 to limit the shielding net 210 along the axial direction of the sleeve 300.

[0050] The first limiting portion 240 and the second limiting portion are configured as two matching annular inclined surfaces, which can evenly and stably clamp the shielding net 210, thereby preventing the shielding net 210 from moving along the axial direction of the sleeve 300 and ensuring the tightness of the fit between the first limiting portion 240 and the second limiting portion.

[0051] Reference Figure 1 and Figure 7 As shown, it can be understood that the sleeve 300 is threadedly connected to the positioning platform 120 of the end head 100, and the inner wall of the sleeve 300 is provided with an annular protrusion 321, and the inner end surface of the sleeve 300 of the protrusion 321 forms an annular receiving groove, and the diameter of the receiving groove is larger than the outer diameter of the adapter 310. The adapter 310 is received in the receiving groove, and the inner diameter of the protrusion 321 is smaller than the outer diameter of the adapter 310 to prevent the adapter 310 from detaching from the receiving groove.

[0052] The adapter 310 is placed in a receiving groove whose diameter is larger than the outer diameter of the adapter 310. At this time, the adapter 310 can rotate relative to the sleeve 300, thereby preventing the second limit portion of the adapter 310 from pressing and rubbing against the shielding net 210 when the user screws in and out the sleeve 300, causing the shielding net 210 to twist, entangle, and other problems, thereby further improving the installation stability of the shielding net 210.

[0053] Reference Figure 7As shown, it can be understood that the outer wall of the adapter 310 is provided with a plurality of guide blocks 311, and the plurality of guide blocks 311 are arranged at intervals along the circumference of the adapter 310. The guide blocks 311 are provided with a first guide portion 312, and the first guide portion 312 is used to guide the adapter 310 into the receiving groove.

[0054] By setting the guide block 311, the guide block 311 guides the adapter 310 into the receiving groove through the first guide portion 312, thereby effectively improving the assembly efficiency of the adapter 310. At the same time, multiple guide blocks 311 abut against the protrusion 321, so that the adapter 310 can be kept in the receiving groove, and the installation stability of the adapter 310 is guaranteed without affecting the rotation of the adapter 310.

[0055] When the user assembles the connector 110, the cable can be connected to the connector 110 first, and then the upper shielding cover 230 can be rotated to engage the upper shielding cover 230 with the lower shielding cover 220. At this time, the anti-overpressure buckle 410 is engaged with the lower shielding cover 220, so that the first matching portion 232 of the upper shielding cover 230 and the second matching portion 225 of the lower shielding cover 220 cooperate to form a ring-shaped first limiting portion 240, and then the shielding net 210 is stretched open, and the shielding net 210 covers the first limiting portion 240 and extends to the outer side walls of the upper shielding cover 230 and the lower shielding cover 220. Then the user can screw in the sleeve 300, so that the adapter 310 in the sleeve 300 automatically cooperates with the first limiting portion 240 to clamp the shielding net 210, thereby completing the fixation of the shielding net 210.

[0056] It can be understood that by providing the overpressure protection component 400 and the adapter 310, the overpressure protection component 400 can make the buckled lower shielding cover 220 cooperate with the upper shielding cover 230 to form an annular first limiting portion 240 and maintain the structural stability of the first limiting portion 240 after the connector 110 is connected, thereby avoiding the problems of matching errors, wrong installation, missing installation, etc. between the lower shielding cover 220 and the upper shielding cover 230, and facilitating subsequent users to use the shielding net 210 to cover the first limiting portion 240 and add the sleeve 300 to improve the assembly efficiency; the first limiting portion 240 cooperates with the second limiting portion of the adapter 310 in the sleeve 300 to automatically clamp the shielding net 210 without the need for an additional locking structure, thereby simplifying the assembly steps and reducing the difficulty of assembly; the lower shielding cover 220 cooperates with the upper shielding cover 230, the shielding net 210 and the sleeve 300 to play a triple shielding role, effectively enhancing the shielding effect.

[0057] Reference Figure 7 As shown, it can be understood that the end of the sleeve 300 away from the end 100 is provided with a sealing opening 330, and the sealing opening 330 is provided with a rubber ring 331, the outer wall of the rubber ring 331 abuts against the inner wall of the sealing opening 330, and the inner wall of the rubber ring 331 abuts against the outer wall of the cable.

[0058] After the user screws in the sleeve 300, the rubber ring 331 can be inserted into the sealing opening 330. The rubber ring 331 shrinks and grips the rubber shell outside the cable, effectively improving the sealing between the cable and the sleeve 300, thereby enhancing the waterproof sealing effect of the shielding device.

[0059] The sealing opening 330 is provided with a second guide portion 332 , which is an annular inclined surface structure provided on the inner wall of the sealing opening 330 . The second guide portion 332 is used to guide the rubber ring 331 to be compressed and enter the sealing opening 330 .

[0060] By providing the second guide portion 332 , the second guide portion 332 can guide the rubber ring 331 to automatically compress and enter the sealing opening 330 , saving the labor cost required for the user to manually compress the rubber ring 331 , effectively improving the assembly efficiency of the rubber ring 331 , and improving the user's usage experience.

[0061] Continue to refer to Figure 7 As shown, it can be understood that the sealing port 330 is connected to a hexagonal nut 333 , and the hexagonal nut 333 is provided with a through hole 334 for the cable to pass through, and the diameter of the through hole 334 is between the inner diameter and the outer diameter of the rubber ring 331 .

[0062] By setting the hexagonal nut 333, the hexagonal nut 333 is threadedly connected to the sealing port 330, which can limit the rubber ring 331 in the sealing port 330, prevent the rubber ring 331 from detaching from the sealing port 330, effectively improve the installation stability of the rubber ring 331, and further improve the sealing performance of the shielding device.
