[0037] Example 1

[0038] This embodiment provides a wire clamping device, as shown in the attached Figure 2-5 As shown, including:

[0039] The wire clamp 11 comprises an upper chamber 111 and a lower chamber 112, which are connected to each other. In this embodiment, the upper chamber 111 is located above the lower chamber 112. The wire passes through the upper chamber 111 and then through the lower chamber 112 to the interior of the leakage protector. The wire clamp 11 is provided with a plurality of connecting bars 113 arranged in a circumferential array. The top ends of the connecting bars 113 are provided with hooks 100. In this embodiment, the connecting bars 113 are located on the outer wall of the upper chamber 111. It can also be considered that the connecting bars 113 cooperate to form part of the upper chamber 111. The hooks 100 extend toward one side of the imaginary central axis of the upper chamber 111. The extension direction can be radially inward or oblique. In this embodiment, the plurality of hooks 100 form the opening of the upper chamber 111. Furthermore, it should be noted that a gap is provided between adjacent connecting bars 113, so that the connecting bars 113 have a certain elastic effect.

[0040] The first sealing member 12 is accommodated in the upper chamber 111. In this embodiment, the first sealing member 12 is located in the upper chamber 111. The first sealing member 12 is provided with a channel 121. One end of the channel 121 is connected to the opening of the upper chamber 111, and the other end of the channel 121 is connected to the lower chamber 112. The wire passes through the opening of the upper chamber 111, the channel 121, and the lower chamber 112, and then extends into the leakage protector.

[0041] Second sealing member 13 is sleeved onto the outer wall of lower chamber 112. Conventional wire-holding devices are divided into a wire clamp 11, a first sealing member 12, and a second sealing member 13. The combination of these components creates a wire-holding seal. Compared to conventional systems, this structural arrangement prevents the formation of flash and improves work efficiency. Furthermore, first sealing member 12 provides internal sealing protection, while second sealing member 13 provides external sealing protection, improving the overall sealing protection level.

[0042] Specifically, as attached Figure 2-4 As shown, first sealing member 12 is provided with a retaining ring 122, which is provided with a through hole 1221. Through hole 1221 forms part of channel 121. The provision of retaining ring 122 creates a constricted opening, improving the sealing effect between the wire and first sealing member 12. Here, retaining ring 122 is located within channel 121, with the outer wall of retaining ring 122 communicating with the inner wall of channel 121. Alternatively, the dimensions of channel 121 can be directly adjusted to accommodate the wire.

[0043] Specifically, as attached Figure 2-4 As shown, the number of retaining rings 122 is at least one. The combination of multiple retaining rings 122 further improves the sealing effect. The number of retaining rings 122 can be adjusted according to actual needs. When the number of retaining rings 122 is multiple, the spacing between two adjacent retaining rings 122 can also be adjusted according to actual needs. In this embodiment, the number of retaining rings 122 is two as an example. In addition, the retaining rings 122 are arranged in an upper and lower manner, and the through holes 1221 of the upper and lower retaining rings 122 are equal in size. Alternatively, the through hole 1221 of the upper retaining ring 122 can be larger than the through hole 1221 of the lower retaining ring 122, forming a gradually shrinking structure.

[0044] Specifically, as attached Figure 2-4 As shown, the retaining ring 122 is provided with a guide portion 1222, and the guide portion 1222 is located on one side of the through hole 1221. The guide portion 1222 forms a guiding effect, so that the wire plays a guiding role when passing through the retaining ring 122.

[0045] Specifically, the guide portion 1222 is inclined toward one end of the lower chamber 112. The guide portion 1222 forms a downward guiding effect. Here, the guide portion 1222 can be an inclined surface or a curved surface.

[0046] Specifically, as attached Figure 2-4 As shown, the upper chamber 111 is provided with a first fixing portion 114. The top surface of the first sealing member 12 abuts against the hook 100, and the first fixing portion 114 abuts against the bottom surface of the first sealing member 12. The hook 100 and the first fixing portion 114 form a clamping and fixing effect at both ends, so that the first sealing member 12 can be better fixed. At the same time, it also provides elastic deformation to ensure compatibility with cables of various specifications.

[0047] Specifically, as attached Figure 2-4 As shown, the first fixing portion 114 includes a groove 1141 and a first inclined surface 1142. The first inclined surface 1142 is closer to the imaginary central axis of the upper chamber 111 than the groove 1141, and the first inclined surface 1142 is connected to the side wall of the groove 1141. The bottom surface of the first sealing member 12 is provided with a second inclined surface 123. One end of the second inclined surface 123 extends into the groove 1141, and the other end of the second inclined surface 123 abuts against the first inclined surface 1142. It should be noted here that the first sealing member 12 is a deformable structure, which will deform during the fixing process. The setting of the groove 1141 and the first inclined surface 1142 can better achieve the effect of coordinated fixing.

[0048] Specifically, as attached Figure 2-4 As shown, the outer wall of the lower chamber 112 is provided with a fixing groove 1121, and the second sealing member 13 is fixed in cooperation with the fixing groove 1121. In addition, the number of fixing grooves 1121 and second sealing members 13 can be adjusted according to actual needs. Two second sealing members 13 can be provided for each fixing groove 1121, or multiple second sealing members 13 can be provided for each fixing groove 1121; or the outer wall of the lower chamber 112 is provided with two or more fixing grooves 1121, each fixing groove 1121 being fixed with a second sealing member 13. Through the combination of multiple forms, the sealing effect is improved.

[0049] Specifically, as attached Figure 2-4 As shown, the outer wall of the second sealing member 13 is provided with a plurality of protrusions 131, which extend outward. The provision of protrusions 131 enables the outer locking cover 14 to better achieve the sealing effect of the second sealing member 13 during the locking process. The number of protrusions 131 can be adjusted according to actual needs. In this embodiment, the number of protrusions 131 is two as an example.

[0050] Specifically, the cable clamp 11 is made of plastic and is integrally molded by plastic injection molding. The first seal 12 is made of silicone or rubber and is integrally molded. The second seal 13 is made of silicone or rubber and is integrally molded. The hardness of the cable clamp 11 is greater than that of the first and second seals 12, 13. It can also be considered that the first and second seals 12, 13 are flexible structures, and the strength of the cable clamp 11 is greater than that of the first and second seals 12, 13.

[0051] Specifically, the wire clamp 11 and the first sealing member 12 and the second sealing member 13 are coaxially arranged.

[0052] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
