Problems solved by technology

However, when connecting by welding, the welding temperature and welding time are not easy to control. When the welding time is short or the welding temperature is low, it is easy to cause virtual welding or desoldering; and when the welding time is long or the welding temperature is high, it is easy to damage the cable core wire. insulation layer, thereby reducing the cable core insulation
Moreover, when welding is used, it is not easy to maintain

Abstract

The invention discloses a combined cable shielding card which comprises a base plate and a combined connection card, wherein a fixed crimping plate is arranged on the base plate, rectangular holes are arranged at the two edges of the fixed crimping plate, the combined connection card is correspondingly connected with the base plate through the rectangular holes and comprises a groove-shaped card support, and a movable crimping plate is arranged in the card support. In the combined cable shielding card, a cable shielding layer is firmly clamped by the movable crimping plate and the fixed crimping plate through extrusion of a crimping bolt, the cable shielding layer and the base plate are reliably connected by an appropriate press force, and the cable shielding layer can be reliably grounded, is high in conductivity, can be combined and disassembled, and is convenient to maintain.

Description

technical field [0001] The invention relates to the field of urban rail transit signal cable construction equipment, in particular to a combined cable shielding card. Background technique [0002] At present, in the construction of urban rail transit signal cables, according to the requirements of relevant specifications, the cable shielding layer needs to be grounded to ensure reliable connection. In the actual construction process, welding is mostly used, although the construction is more convenient and the cost is lower. However, when connecting by welding, the welding temperature and welding time are not easy to control. When the welding time is short or the welding temperature is low, it is easy to cause virtual welding or desoldering; and when the welding time is long or the welding temperature is high, it is easy to damage the cable core wire. The insulation layer, thereby reducing the cable core insulation. Moreover, when the welding method is adopted, it is not ea...
