Problems solved by technology

The known sealing device for cable penetration usually adopts two sealing forms for round cables, the filling filler and the cylindrical rubber block with a hole in the middle. Since the surface of the flat cable is smooth and cannot be polished, the bonding between the filling filler and the cable surface is not good. In a dynamic environment, the adhesive layer is prone to delamination, which affects the sealing performance; the cylindrical rubber block with a hole in the middle is not suitable for flat cables, and the deformation of each part of the cylindrical rubber block after contact with the hatch cover tends to be consistent, and the sealing Reliability is difficult to meet the high sealing performance requirements in dynamic environments, so it is urgent to develop a flat cable cabin penetration sealing device to solve the above problems

Embodiment

[0037] The plug 1 of the flat cable first passes through the rectangular through hole on the sealing gland 4, then penetrates the sealing hatch 3, and finally passes through the rectangular through hole on the sealing hatch 3; The through-holes passing through the flat cable 2 are all in the shape of a slot; the gap on the elastic sealing block 6 for passing through the flat cable 2 is broken, and the flat cable located between the sealing hatch 3 and the sealing gland 4 is tightly embedded 2 A certain position; when installing, align the slot-shaped through hole with a width of 1mm in the middle of the pad 5 in parallel with the flat cable 2, and then pass through the flat cable 2; put the elastic sealing block 6 embedded in the flat cable 2 together with the pad 5 Put it into the sealing hatch cover 3, enter the hole position corresponding to the cushion block 5 in the sealing hatch cover 3 with the cushion block 5 and install it in place; then install a piece of cushion bloc...

Abstract

The invention discloses a flat cable penetration sealing device with high sealing property in a dynamic environment. According to the device, a flat cable is embedded into a gap of an elastic sealing block, the elastic sealing block is put into a circular hole of a sealing cabin cover, two cushion blocks are respectively mounted on two small end faces of the elastic sealing block, a sealing gland and the sealing cabin cover are in fastened connection by screwing the bolts, the elastic sealing block is axially extruded by the sealing gland so as to gradually deform outwards, so that cone seal is formed between the sealing gland and a circular truncated cone-shaped hole of the sealing cabin cover, plane seal is formed between the elastic sealing block and the flat cable, and internal and external dual seal functions are realized. The section diameter of the circular truncated cone-shaped hole of the sealing cabin cover is gradually reduced, the compression degree of the elastic sealing block is gradually increased, and high sealing property can be achieved, so that the sealing property with the same order as that of the cone seal is achieved, and flat cable penetration seal with high sealing property in the dynamic environment is met.

Description

technical field [0001] The invention belongs to the technical field of sealing devices, and in particular relates to a flat cable cabin penetration sealing device with high sealing performance in a dynamic environment. Background technique [0002] Flat cables are more and more used in electronic systems because of their small size, high reliability, and suitability for transmitting large pulse currents. When two components connected by flat cables are located in different compartments separated by hatches, flat The cables need to pass through the hatch cover. If the system requires the cabin to be sealed, the flat cable must be sealed through the cabin. The known sealing device for cable penetration usually adopts two sealing forms for round cables, the filling filler and the cylindrical rubber block with a hole in the middle. Since the surface of the flat cable is smooth and cannot be polished, the bonding between the filling filler and the cable surface is not good. In a...
