A mixed bundled cable for wall-penetrating sealing and its application method

Abstract

A mixed bundled cable for sealing through walls, including a cable core, a sheath, and a reinforcement mechanism, the reinforcement mechanism includes a filling layer, a crimp sleeve, an armor layer, and a reinforcement sleeve; the cable core is provided with multiple, and The gaps between the plurality of cable cores and the outer periphery are filled with the filling layer; the crimping sleeve is provided on the outside of the filling layer, and the crimping sleeve adopts a C-shaped ring structure. The sleeve is used to fix the cable core and the filling layer; the outer side of the crimping sleeve and the filling layer that has not been crimped is wrapped around the armor layer, and the outer side of the armor layer is sleeved with the reinforcing sleeve ; The outer side of the reinforcing sleeve wraps the sheath. The invention uses the crimping sleeve to fix the cable and the filling layer, and protects the cable when it is squeezed and sealed with the gland through the circular reinforcing sleeve. It is not affected by radial force and avoids squeezing the transmission signal cable. The emergence of signal transmission insertion loss caused by deformation increases, which effectively guarantees the transmission performance of the cable.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to a mixed bundled cable for sealing through walls and a method for using the same Background technique [0002] Cable is a general term for items such as optical cables and cables; cables have many uses, mainly used for multiple functions such as control installation, connection equipment, and power transmission. It is a common and indispensable thing in daily life. Because cables are charged, So installation requires special care. [0003] In some applications that require dust and water resistance, there are more and more requirements for cable penetration seals on equipment, and the application of circular glands is also more and more applied to chassis or wall penetration seals. The sealing principle of the cable gland is to achieve the sealing effect by clamping the sealing rubber ring and extruding the cable. At the same time, with the increase of communication capacity and ...

Problems solved by technology

At the same time, with the increase of communication capacity and complexity, there are more and more connections and transmissions of different signals between the chassis. Cables of different types and core diameters need to be bundled and passed through the chassis or bulkhead; The outer diameter of the cable is not round, which will have a certain impact on the sealing effect. At the same time, if there is no protective measure during the extrusion process, the inner cable core is susceptible to stress, which may affect the risk of signal transmission, especially for sensitive lines such as optical fibers. cable
