When the first wire passing hole 1011 is not connected with the cable 3, the plug 5 is plugged into the first wire passing hole 1011 and the second wire passing hole 203, and the plug 5 is matched with a dust cap to play a role in dust prevention and sealing. The string connecting piece 6 is bent at will, the end part of the string connecting piece is inserted into a corresponding hole position of the base 4 and fixed through the clamping ring 601 at the end part, the clamping ring 601 is an elastic ring integrally formed with the string connecting piece 6, the diameter of the clamping ring 601 is larger than that of the hole position, the clamping ring deforms and shrinks under the action of external force, when the external force is large enough, the clamping ring 601 deforms enough to enable the string connecting piece to be pulled out of the hole position, and at the moment, the string connecting piece 6 is separated from the base 4. The snap ring 601 may also be a detachable metal ring, and is fastened to the end of the string-connecting member 6.

When the cable holding component 1 is installed, the plug 5, the pressure piece 2 and the connecting piece 102 are taken out, the cable 3 is clamped in from the corresponding hole position on the holding component 1, then the pressure piece 2 and the connecting piece 102 are installed back, the hole position where the cable 3 is not installed is plugged by the plug 5, and the pressure piece 2 is fixed through the corresponding fastening piece, so that the pressure piece 2 continuously applies pressure to the holding component 1. The plug 5 is made of flexible or elastic material, and the plug at the corresponding part is suspended at one side when the cable is installed.

String connecting piece 6 and stopper 5 are when crossing the line hole and not having the cable, and the sealed line hole of crossing is filled in to stopper 5, avoids the dust to get into the fixed effect of follow-up cable of influence. When the wire passing hole is fully loaded, the plug 5 is taken out, and the plug 5 is connected to the side part of the base 4 in a suspension manner through the serial connection piece 6, so that the plug 5 is prevented from being lost, and the subsequent reuse is facilitated.

A sealing ring 7 is arranged on one surface of the base 4 close to the electric equipment, and the sealing ring 7 surrounds the periphery of the wire passing notch 401; the base 4 with the consumer laminating compresses tightly sealing washer 7, and sealing washer 7 seals the region between base 4 and the consumer at line groove opening 401 place.

As shown in fig. 1-10, the fixing member includes four transverse rows of first fixing members and one longitudinal row of second fixing members, wherein the first fixing members have 40 holes in total, the second fixing members have 4 holes in total, and the holes in the first fixing members and the second fixing members have two different specifications.

The sealing ring 7 surrounds the periphery of the wire passing notch 401, as shown in fig. 3 and 4, the sealing ring 7 is of an integral structure and is rectangular or annular; the sealing ring 7 may also be a split structure, and when the split structure is adopted, the sealing ring includes two parts, namely a first part and a second part, wherein the first part surrounds the periphery of the wire passing notch 401 for installing the first fixing piece in the four transverse rows, and the second part surrounds the periphery of the wire passing notch 401 for installing the second fixing piece in the longitudinal row.

Be equipped with the recess that is used for installing sealing washer 7 on the base 4, sealing washer 7 is made by elastic rubber material, and the interference embedding is in the recess 402, interference formula embedding structure makes it not need viscidity chemical material fixed, and it is more convenient to install.

One side of the base 4 close to the electric equipment is provided with a plurality of mounting holes, and the sealing ring 7 is provided with an elastic gasket 701 corresponding to the mounting holes, as shown in fig. 4. The mounting hole is a countersunk hole, the central hole of the elastic gasket 701 is collinear with the central axis of the mounting hole, and the elastic gasket 701 is embedded in the countersunk structure of the mounting hole in a clamping manner.

As shown in fig. 11 and 12, the pressure member 2 includes two first splicing plates 2011 and two second splicing plates 2012 which are aligned with each other, wherein one end of the first splicing plate 2011 is pressed on the upper portion of one end of the second splicing plate 2012, and the other end of the second splicing plate 2012 is pressed on the upper portion of the other end of the first splicing plate 2011; a second wire passing hole 203 corresponding to the first wire passing hole 1011 is formed at the joint of the first splicing plate 2011 and the second splicing plate 2012; and connecting holes 2013 are formed in the corresponding positions of the two ends of the first splicing plate 2011 and the second splicing plate 2012. The length of the plug 5 is not less than the sum of the depths of the first wire through hole 1011 and the second wire through hole 203, and a dust cap is arranged at the inlet of the plug 5 close to the second wire through hole 203, and the diameter of the dust cap is greater than that of the second wire through hole 203.

The pressure piece 2 is connected with the base 4 through a threaded piece 202 matched with the connecting hole 2013, and a threaded hole 403 matched with the threaded piece 202 is formed in the base 4. The pressure member 2 is designed symmetrically, and two substantially identical components, such as the first splice plate 2011 and the second splice plate 2012, are relatively buckled together to form an integral stress member, so that the clamping assembly is pressed and clasped under the locking force of the two screws 202.

The above are merely examples of the present application and are not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
