Description

The data line used for connecting the smart energy meter with the special variable acquisition terminal

technical field

The utility model relates to information data collection equipment in the electric power industry, in particular to a data line used for connecting an intelligent electric energy meter with a special variable collection terminal.

With the popularization of power consumption information collection system, customers of 50kVA and above special transformers install smart energy meters and special transformer collection terminals are widely used. Through special transformer collection terminals, the electricity consumption information of special transformer users is collected to realize the collection of electric energy meter data, Monitoring of the working condition of electric energy metering equipment and power quality of power supply, as well as monitoring of customer's electric load and electric energy, and management and two-way transmission of collected data. The current data transmission mostly uses RS-485 two-core multi-strand shielded communication lines. Due to the large number of terminals for special variable acquisition terminals and smart energy meters, it is necessary to carefully distinguish and identify the correct 485 interface when wiring, and the wiring efficiency is low. In addition, the cross-sectional area of the multi-strand annealed copper wire of the commonly used RS-485 communication line is about 1 square millimeter. When connecting, the multi-strand wire at the end of the wire is easy to split, and the crimping contact area between the data line and the top wire of the terminal is small. In order to avoid problems such as loose multi-strand wires and weak top pressure after crimping, the connection section of the wire needs to be processed. Therefore, its connection effect and work efficiency are greatly affected by human factors, and it cannot be The phenomenon of recalling and testing data happens from time to time.

Example 1

It can be seen from Figures 1 to 3 that the technical solution of the utility model includes a first connector 1, a second connector 2, and a data line 4; the first connector 1 and the second connector 2 are composed of connector body A and The positioning member B is composed of a wing plate, which is arranged on the lower part of one side or both sides of the joint body A of the first and second joints. The width of the first joint 1 and the second joint 2 (joint body A and The overall width of the positioning member B) is respectively the same as the width of the card slot of the terminal block of the equipment connected to it.

The joint bodies A of the first connector 1 and the second connector 2 are respectively provided with two columnar plug contacts 3, the plug contacts 3 are metal columns with a diameter of Φ2.5 mm and a length of 9 to 15 mm. The hardness and the cross-sectional area of the connection section between the wire and the device are determined; the data line 4 is a two-core shielded wire; the two ends of the data line 4 are electrically connected to the plug contacts 3 of the first connector 1 and the second connector 2 respectively ;
