detailed description

The utility model proposes a secondary cable alignment device, which includes two sets of alignment lights, and the alignment lights include a grounding wire, a power supply, a light bulb and a test wire connected in series in sequence, and the power supply and The light bulbs are connected in series through wires. The secondary cable alignment device of the utility model can accurately distinguish and judge whether the cables connected to different cabinets are the same cable in a short time, and is reliable in use.

In order to have a clearer understanding of the technical features, purpose and effects of the utility model, the specific implementation, structure, features and effects of the secondary cable alignment device proposed by the utility model are described in detail below in conjunction with the accompanying drawings and preferred embodiments The description is as follows. In addition, through the description of specific implementation methods, the technical means and functions adopted by the utility model to achieve the predetermined purpose can be understood more deeply and specifically, but the accompanying drawings are only for reference and illustration, and are not used to explain the utility model. be restricted.

Fig. 1 is a schematic diagram of the composition and structure of the secondary cable alignment device of the present invention. FIG. 2 is a schematic diagram of another composition and structure of the secondary cable alignment device of the present invention.

As shown in Figure 1, the secondary cable alignment device proposed by the utility model includes an alignment lamp 1, and the alignment lamp 1 includes a grounding wire 11, a power supply 12, a light bulb 13 and a The test lead 14, and the power supply 12 and the indicator light bulb 13 are connected in series through a lead 15. Wherein, in a preferred embodiment, there are two groups of the line-to-line lights 1 . In addition, preferably, the power source 12 is two 5V dry batteries, of course, the power source can also be a storage battery, a rechargeable battery and the like.

When working, the ground wires 11 of the two paired lights 1 are correspondingly grounded, and the two test wires 14 are respectively connected to the cores of the two cables. The line lamp 1 and the cable form a loop, and it can be judged that the cables where the two wire cores are located are the same cable, and vice versa.

Preferably, the free end of the ground wire 11 is connected to a conductive clamp (not shown in the figure), or the free end of the ground wire 11 is bent to form a clamp. By arranging a wire clip or clamp at the other end of the ground wire, it can be conveniently used for a stable connection, avoiding falling off during work, and ensuring work reliability.

As shown in the figure, in a preferred embodiment, one end of the ground wire 11 is connected to the negative pole of the power supply 12 , and the indicator light bulb 13 is connected to the positive pole of the power supply 12 through the wire 15 . Of course, it is not limited to this in practical applications, and vice versa.

Wherein, the end of the free end of the test lead 14 is a needle connector. Since the wire core of the cable is usually thin in diameter, the needle connector can be used to contact the wire core conveniently, which is convenient and reliable during use.

Please refer to Fig. 2, in the preferred embodiment, for ease of use, a battery box 16 made of epoxy resin is provided in addition, the dry battery is installed in the battery box 16, the grounding wire 11 and the light bulb 13 are respectively electrically connected to the battery boxes 16 .
