Control cable aligner based on network cable tester

technical field

The utility model relates to an improvement of a cable alignment device, in particular to a control cable alignment device based on a network cable measuring device, which is mainly used in electric power systems, telecommunications and other departments for accurate alignment of cable cores to ensure that the entire The progress and quality of the works.

Background technique

In the power system, the wiring of control cables is a very important task, especially in the construction or upgrading of substations, the wiring of a large number of cables plays a pivotal role in the entire project. The most critical step in the cable wiring work is the alignment of the wire cores. Whether the alignment can be done quickly and accurately affects the progress and quality of the entire project to a large extent. At present, we usually use the method of manually connecting the multimeter and the mobile phone or walkie-talkie one by one. The disadvantages of this method are: first, the use of mobile phones or walkie-talkies will generate a large amount of wireless interference, which threatens the normal operation of the protection device; second, the efficiency of manual alignment is low, and it is difficult to detect short-circuit faults between wire cores.

It can be seen through retrieval that in order to overcome the deficiencies in the prior art above, there are many reports about cable alignment devices, such as Chinese patent CN201210252710.4 disclosing "a digital cable alignment device"; Chinese patent CN200810231134.9 disclosing a A "cable pair tester"; Chinese patent CN201120047183.4 discloses an "electronic cable aligner"; Chinese patent CN201220394245.3 discloses an "intelligent cable aligner". The above patented technologies can realize accurate alignment of cables and avoid wireless interference, but the structure is relatively complicated.

Contents of the invention

The purpose of the utility model is to provide a control cable alignment device based on a network cable line measuring device, which can not only realize accurate alignment of cables and avoid wireless interference, but also has a simple structure and is easy to assemble.

In order to achieve the above purpose, the technical solution adopted by the utility model is: the control cable aligner based on the network cable tester includes a connecting cable, and there are 8 core wires in the connecting cable; it is characterized in that: One end of the connection cable is connected to the crystal head plug, and the crystal head plug is plugged into the network cable tester; the other end of the connection cable is connected to the cable joint controller, and the side wall of the cable joint controller is provided with 8 There are 8 cable core wire jacks, and the 8 cable core wire jacks are numbered sequentially from 1 to 8. There is a metal wire clip in each cable core wire jack, and the connection cable is connected to one end of the cable connector controller. The 8 core wires are sequentially connected with the 8 metal wire clamps one by one.

The utility model is also implemented through the following measures: the network cable tester and the crystal head plug are network cable testers, and there are finished products on the market. A set of equipment includes two components, the main tester and the remote tester, which need to be used in conjunction , each part is provided with an RJ45 port, so no more details.

The beneficial effect of the utility model is that: the control cable alignment device based on the network cable line measuring device is assembled by using the existing network line line measuring device, so it can not only realize the accurate alignment of the cables, avoid wireless interference, and Simple structure, easy assembly, low production cost, easy operation, and easy to carry; it can realize the alignment work of control cables with various diameters of 8 cores and below that are most used in the field, and can greatly improve the alignment speed of control cables and accelerate The progress of substation construction or upgrading works.

detailed description

Make the utility model with reference to Fig. 1. The control cable alignment device based on the network cable tester includes a connection cable 1, and 8 core wires are arranged in the connection cable 1; it is characterized in that: one end of the connection cable 1 is connected to a crystal head plug 2, The crystal head plug 2 is plugged into the network cable tester 3; the other end of the connecting cable 1 is connected to the cable connector controller 4, and 8 cable core wire jacks 5 are arranged on the side wall of the cable connector controller 4 , 8 cable core wire jacks 5 are sequentially numbered from 1 to 8, each cable core wire jack 5 is provided with a metal wire clip 6, and the connection cable 1 is connected to the 8 at one end of the cable connector controller 4 The core wires are connected to the eight metal wire clips 6 one by one in turn.

As an improvement of the present utility model: the network cable tester 1 and the crystal head plug 2 are network cable testers, and there are finished products on the market. A set of equipment includes two components: the main tester and the remote tester, which need to be used in conjunction , each part is provided with an RJ45 port, so no more details.

Fig. 2 provides a schematic top view of the application state of the utility model. With reference to Fig. 2, when using the utility model, need to prepare two control cable aligners based on the network cable tester, one is connected to the near end of the tested cable 7, and the other is connected to the far end of the tested cable 7. , if there is no open circuit or short circuit in the core wire of the tested cable 7, the indicator lights of the network cable tester 3 at the near end will flash one by one from 1 to 8; while the indicator lights of the network cable tester 3 at the far end will The order of the wire numbers connected to the near-end network cable tester 3 will flash one by one; when some wires are disconnected, the indicator lights of the near-end network cable tester 3 will not light up, and other lights can still be turned on one by one. Flashing; when the number of non-broken wires is as low as 0 or 1, the indicator lights corresponding to the wire numbers of the near-end network cable tester 3 and the remote network cable tester 3 are all off; when there are two core wires When short-circuited, the indicator lights of the near-end network cable tester 3 are still flashing one by one in the order from 1 to 8, while the indicator lights corresponding to the two short-circuit lines of the far-end network cable tester 3 will be lit at the same time. Other indicator lights are still flashing one by one in the normal order; when there are three or more wires short-circuited, the indicator lights of the near-end network cable tester 3 are still flashing sequentially from 1 to 8, while the far-end network cable tester 3 is still flashing sequentially. The indicator lights corresponding to all the short-circuit wires of the cable controller 3 are not on; through the indication of the above signal lights, it is possible to quickly determine the corresponding relationship between the wire cores and whether there is a wire core disconnection or short circuit.
