Problems solved by technology

[0006] However, when such a flexible part is equipped with a tearable inner region, the pulling force applied to the gripping member in order to tear this part causes uncontrolled deformation of the flexible part and makes it difficult to tear the part or torn beyond the boundary of the weak line

Embodiment Construction

[0021] As previously stated, the present invention relates to a wall element for the hermetic passage of cables, for example useful as a wall element for sealed electrical boxes or ducts.

[0022] This wall element basically comprises a rigid part 1 and a flexible part 2, wherein the rigid part has an opening 10 and the flexible part 2 closes the opening 10 in the initial configuration given to the wall element at the time of manufacture.

[0023] In the center of the opening 10 , the flexible part 2 comprises one or more inner regions like region 20 .

[0024] Area 20 is bounded by an annular line of weakness 21 and is equipped with gripping members 31 .

[0025] The gripping member 31 makes it possible to remove this area 20 by tearing the flexible portion 2 along the line of weakness 21, thereby making it possible to give the wall element a new configuration in the initial position of the inner area 20, usually called a working configuration, in which case In this configur...

Abstract

The invention relates to a wall element for sealingly passing a cable which is used, in particular, in the form of a wall element for a tight electric box or a tube, wherein said wall element has initial and operating configurations and comprises a rigid partition (1) perforated by an opening and a flexible partition (2) which closes said rigid partition in the initial configuration of the wall element, the flexible partition comprises at least one internal area (20) which is substantially arranged at the orifice center, is flanged by an annular weakness line and is provided with a grasping member (31) which makes it possible to detach said internal area by tearing the flexible partition (2) along the weakness line in such a way that the wall element is placeable in the operating configuration thereof. According to the invention, the grasping member (31) consists of a tongue connected to a rigid ring (32) adhering to the internal area (20) of the flexible partition (2).

Description

technical field [0001] In general, the present invention relates to wiring technology, especially wiring technology in the electrical field. [0002] More precisely, the invention relates to a wall element for sealing the passage of cables, in particular usable as a wall element for sealed electrical boxes or ducts, and having at least one initial configuration and one In the working configuration, the wall element comprises a rigid part with an opening and a flexible part closing the opening in the initial configuration of the wall element, the flexible part comprising at least one inner region arranged substantially in the center of the opening in an annular weak The weakness line is bordered and equipped with gripping members making it possible to remove the inner area by tearing the flexible part along the line of weakness, thereby setting the wall element to its initial configuration. Background technique [0003] Such a wall element is described in patent FR 1 388 822...
