Novel fixture for special hollow waveguide soft leakage cable

Abstract

The invention discloses a novel fixture for a special hollow waveguide soft leakage cable. The novel fixture comprises a base for accommodating the special hollow waveguide soft leakage cable, a coverplate and a connecting bearing, wherein the base is hinged to the cover plate by the connecting bearing; a bearing connecting seat is arranged on one side of the base; a shaft hole for allowing the connecting bearing to pass through is formed in the center of the bearing connecting seat; a buckle accommodating cavity for accommodating and clamping a buckle is formed in the other side of the base;a directional groove is formed in the bottom of the base; a shaft connecting buckle is arranged on one side of the cover plate; a shaft hole for allowing the connecting bearing to pass through is formed in the center of the shaft connecting buckle; the buckle is arranged on the other side of the cover plate and is in fit meshed clamping with the buckle accommodating cavity; leaf springs are alsoconnected to the inner side of the cover plate. The novel fixture for the special hollow waveguide soft leakage cable, disclosed by the invention, has the advantages of simple structure and convenience in disassembly and assembly; the fixture and the cable are mounted to be in place by simple buckle operation; besides, by adopting asymmetrical design, a cable body can be hooked and held in a channel.

Description

technical field [0001] The invention relates to a cable fixing device, in particular to a fixture with a special shape for fixing a special hollow-core waveguide soft leaky cable. Background technique [0002] With the development of urban rail transit construction, the train-to-ground wireless system needs more reliable security to ensure the safe operation of the line. Therefore, four key factors need to be met. First, use a transmission frequency that is more than twice or higher than that of the operator's system to avoid interference. 2. It is necessary to form sufficient coverage field strength along the track; 3. It is necessary to bear the high-frequency flexible waveguide air-core leaky cable that bears the field intensity radiation; For reliable fixation. [0003] The laying of waveguide leaky cables along the rail transit lines has become a key task to ensure smooth communication. In the laying construction of various lines, a large number of cable clamps are u...

Problems solved by technology

The advantage of this clamp is that it can be used repeatedly. The disadvantage is that the buckle points of the slot are fixed (2 to 3 are mentioned in the literature), and the cable may not be clamped or clamped too tightly during installation. , resulting in the stability not being guaranteed; secondly, the ability to resist external interference is weak

Chinese Invention Patent Application Publication No. CN1021555A, Utility Model Patent CN201723848U discloses a cable clamp, including two parts of the bottom plate and the cover body, the side wall of the card seat and the side wall of the cover body are connected by flexible strips, the cover body and the card seat There is a buckle-type connection between them.
