Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of line sequence tester, concretely is a simple and convenient line sequence tester. BACKGROUND

[0002] Most of the photoelectric composite cable assemblies on the market adopt a light and two electricity structure, one light refers to one optical fiber, two electricity refers to two power lines, the optical fiber plays a role in signal transmission, and the power line is used for energizing the equipment. For the equipment connected with power input, such as power supply for active equipment (such as optical network unit, small base station equipment, etc.) in remote communication base station through photoelectric composite cable assembly, correct connection of positive and negative poles is the basic condition for normal start and operation of the equipment. If the positive and negative poles are connected in reverse, the electronic components inside the equipment may not work normally or even be damaged seriously due to the wrong current direction. For example, for some integrated circuit chips with polarity requirements, reverse voltage may damage the transistors and other components inside the chip, causing the entire equipment to malfunction. Therefore, the positive and negative pole sequence of the photoelectric composite cable assembly is an extremely important performance indicator, and the accuracy of the polarity must be completely guaranteed during production and processing, so as to avoid the occurrence of equipment damage caused by reverse line sequence.

[0003] After retrieval, patent publication No. CN219957837U discloses a line sequence tester convenient for fixing data lines, which comprises a sequencer with a data line sequence detection function. The lower surface of the sequencer is fixedly connected with a base, and the upper surface of the base is provided with a fixing device. The line sequence tester convenient for fixing data lines stores the traditional rubber band bundled data lines in the fixing device by setting, and uses the storage groove in the fixing device to store and fix the data lines. The data lines can be stored in large quantities, and the funnel-shaped lower end opening of the storage groove can slide out the data lines, making it convenient to take the data lines. An electric heating rod is installed in the upper end of the fixing box and retracts inward. When the bundled data lines pass through the feeding slot, the electric heating rod melts the rubber band on the surface of the data lines, and the data lines can be easily disassembled in the storage groove, thereby having the characteristics of conveniently fixing the data lines to be tested.

[0004] At present, the power lines of photoelectric composite cable assemblies are generally red and blue. The line sequence can be determined by directly observing the color of the cable sheath. However, if the cable has been used for a long time, the sheath color fades or wears out, or visual fatigue is caused by long-term visual observation, which may lead to line sequence errors. Therefore, a simple and convenient line sequence tester is designed. UTILITY MODEL CONTENTS
