Sealing wall through device and method using the device

Abstract

The invention provides a sealing wall through device for enabling a wire harness to pass through the wall, and a method using the device. The sealing wall through device comprises a shell, a shield earthing module and a sealing core; the shield earthing module is arranged in the shell and contacts with an inner surface of the shell; a first through hole for the penetrating the wire harness is arranged in the shield earthing module; the sealing core is arranged in the shell and is provided with a second through hole for the penetration of the wire harness. The sealing core and the shield earthing module are opposite to each other so that the first through hole is aligned with the second through hole; the sealing core is made of elastic material so that the wire harness can elastically contact with the inner wall of the second through hole when penetrating through the second through hole; and the shell and the shield earthing module are constructed to be conductive. Through the device and method provided by the invention, the effective earthing and sealing can be provided when multiple wire harnesses penetrate through the wall without additionally arranging an earthing bracket and like structures; the small weight, the concise structure and the shielding effect can be realized when the earthing and sealing are performed.

Description

technical field [0001] The invention relates to the electrical field, in particular to a sealed wall penetration device and a method for using the device. Background technique [0002] When the wires need to pass through the wall, it is necessary to set up a sealed wall-through device. The existing more commonly used sealed wall-through devices usually have such a structure: holes are opened on the installation panel for the wall-through parts to pass through, and the wall-through There are card slots and retaining rings for interlocking on the parts and the mounting panel, but due to size reasons, the card slots and retaining rings may not be aligned for installation. At this time, additional devices may be needed to help the card slots and retaining rings Alignment with each other, or simply cannot be installed, and such a device can only pass through one wire harness; Connected grounding brackets, this kind of grounding shielding effect is relatively poor, and the additi...

[0002] When the wires need to pass through the wall, it is necessary to set up a sealed wall-through device. The existing more commonly used sealed wall-through devices usually have such a structure: holes are opened on the installation panel for the wall-through parts to pass through, and the wall-through There are card slots and retaining rings for interlocking on the parts and the mounting panel, but due to size reasons, the card slots and retaining rings may not be aligned for installation. At this time, additional devices may be needed to help the card slots and retaining rings Alignment with each other, or simply cannot be installed, and such a device can only pass through one wire harness; Connected grounding brackets, this kind of grounding shielding effect is relatively poor, and the additional brackets will increase the weight, inconvenient installation and maintenance; moreover, the outer shielding layer of the wiring harness usually cannot enter the sealed wall penetration device, so there is a leakage point, This may introduce external interference
