Discontinuous shielding adhesive tape for data communication cable and manufacturing method of discontinuous shielding adhesive tape

Abstract

The invention discloses a discontinuous shielding adhesive tape for a data communication cable and a manufacturing method of the discontinuous shielding adhesive tape. The shielding adhesive tape comprises a first tape layer; a metal layer is mounted on the top of the first tape layer; the width of the metal layer is smaller than the width of the first tape layer; a plurality of nicks are equallyspaced at the top of the metal layer; the metal layer is divided into a plurality of independent metal elements by the plurality of nicks; portions of one side of the first tape layer, which extend out from a corresponding side of the metal layer, are set to be blank regions; and the bottom portion of the metal layer and the top portion of the first tape layer are filled with glue; the length of the metal layer is equal to the length of the first tape layer; and the blank regions of the first tape layer are used to prevent the short circuiting of the metal layer. The discontinuous shielding adhesive tape of the invention is economical and practical. Nicks will not appear in the blank regions of the first tape layer when the metal layer is nicked, and therefore, the shielding adhesive tapewill not be fractured during a stretching process, and the shielding adhesive tape has better integrity.

Description

technical field [0001] The invention relates to the technical field of shielding tapes, in particular to a discontinuous shielding tape for data communication cables and a manufacturing method thereof. Background technique [0002] The communication cable used for data communication is usually composed of multiple groups of twisted pairs, which are wrapped in the cable sheath, but there will be signal interference between two adjacent communication cables, in order to solve the problem of adjacent communication cables The problem of signal interference between them, the discontinuous shielding tape for data communication will appear on the market. The discontinuous shielding tape for data communication includes the first tape layer and the tape installed on the first tape layer. The metal layer, and the length and width of the first belt layer and the metal layer are the same, when the metal layer is scored with a scoring punch, the scoring punch is easy to scratch the first...

[0002] The communication cable used for data communication is usually composed of multiple groups of twisted pairs, which are wrapped in the cable sheath, but there will be signal interference between two adjacent communication cables, in order to solve the problem of adjacent communication cables The problem of signal interference between them, the discontinuous shielding tape for data communication will appear on the market. The discontinuous shielding tape for data communication includes the first tape layer and the tape installed on the first tape layer. The metal layer, and the length and width of the first belt layer and the metal layer are the same, when the metal layer is scored with a scoring punch, the scoring punch is easy to scratch the first belt layer, so that the first belt layer is pulled It is prone to breakage during stretching, and the integrity of non-continuous shielding tapes for data communication is poor
