Description
技术领域technical field
本实用新型涉及电能表技术领域，尤其涉及一种电能表外部通讯接口。The utility model relates to the technical field of electric energy meters, in particular to an external communication interface of the electric energy meter.
背景技术Background technique
电能表上设有外部通讯接口，主要用于与外部抄表设备进行通讯连接，但是现有技术的通讯接口是两组接线端子，需要用户自己手动将抄表设备与接线端子进行接线，这样不但接线麻烦，使用不是很方便，而且不能给抄表设备供电，所以外部供电设备需要自带电源，使得抄表设备成本较高。There is an external communication interface on the electric energy meter, which is mainly used for communication connection with external meter reading equipment. The wiring is cumbersome, it is not very convenient to use, and it cannot supply power to the meter reading equipment, so the external power supply equipment needs to have its own power supply, which makes the meter reading equipment more costly.
发明内容Contents of the invention
本实用新型所采用的技术方案是：提供一种接线方便且自带电源的电能表外部通讯接口。The technical scheme adopted by the utility model is: to provide an external communication interface of the electric energy meter with convenient wiring and self-contained power supply.
本实用新型所采用的技术方案是：一种电能表外部通讯接口，包括电路板以及设置在电路板上的两组连接端子，每组接线包括正负接头，它还包括两个RJ45接口，且每个RJ45接口上设有八个接头，所述第一第二接头分别与电能表中的正负供电电极连接，第四第五接头分别与其中一组连接端子的正负接头连接，第三第六接头为预留空接头，第七第八接头接地。The technical solution adopted by the utility model is: an external communication interface of an electric energy meter, including a circuit board and two groups of connecting terminals arranged on the circuit board, each group of wiring includes positive and negative connectors, and it also includes two RJ45 interfaces, and Each RJ45 interface is provided with eight connectors, the first and second connectors are respectively connected to the positive and negative power supply electrodes in the electric energy meter, the fourth and fifth connectors are respectively connected to the positive and negative connectors of one group of connection terminals, and the third The sixth joint is a reserved joint, and the seventh and eighth joints are grounded.
采用以上结构与现有技术相比，本实用新型具有以下优点：在连接端子上设置RJ45接口，这样接线更加方便，并且RJ45接口与电能表中的供电电极连接，这样抄表设备就不需要再带电源了，只需要将抄表设备插接到RJ45接口上即可得电工作，使用更加方便，而且RJ45接口本身的信号质量也较好。Compared with the prior art by adopting the above structure, the utility model has the following advantages: an RJ45 interface is set on the connecting terminal, so that the wiring is more convenient, and the RJ45 interface is connected with the power supply electrode in the electric energy meter, so that the meter reading equipment does not need to be connected again. With a power supply, you only need to plug the meter reading device into the RJ45 interface to get electricity to work, which is more convenient to use, and the signal quality of the RJ45 interface itself is also better.
作为优选，所述两个RJ45接口均设置在电路板边缘，且两个RJ45接口的下端均与电路板下端对齐。这样设置，用户插接更加方便，而且更加美观。Preferably, the two RJ45 interfaces are both arranged on the edge of the circuit board, and the lower ends of the two RJ45 interfaces are aligned with the lower end of the circuit board. With this arrangement, it is more convenient for users to insert and connect, and it is more beautiful.
作为优选，它还包括用于放置抄表设备的放置架。这样设置，用户抄表时更加方便轻松。Preferably, it also includes a shelf for placing meter reading equipment. This setting makes it more convenient and easy for the user to read the meter.

如图所示：1、电路板；2、RJ45接口。As shown in the figure: 1. Circuit board; 2. RJ45 interface.
具体实施方式Detailed ways
以下结合附图与具体实施方式对本实用新型做进一步描述，但是本实用新型不仅限于以下具体实施方式。The utility model is further described below in conjunction with the accompanying drawings and specific embodiments, but the utility model is not limited to the following specific embodiments.
一种电能表外部通讯接口，包括电路板1以及设置在电路板1上的两组连接端子，每组接线包括正负接头，它还包括两个RJ45接口2，且每个RJ45接口2上设有八个接头，所述第一第二接头分别与电能表中的正负供电电极连接，第四第五接头分别与其中一组连接端子的正负接头连接，第三第六接头为预留空接头，第七第八接头接地。An external communication interface of an electric energy meter, including a circuit board 1 and two groups of connecting terminals arranged on the circuit board 1, each group of wiring includes positive and negative connectors, it also includes two RJ45 interfaces 2, and each RJ45 interface 2 is provided with There are eight connectors, the first and second connectors are respectively connected to the positive and negative power supply electrodes in the electric energy meter, the fourth and fifth connectors are respectively connected to the positive and negative connectors of one group of connection terminals, and the third and sixth connectors are reserved Empty joints, the seventh and eighth joints are grounded.
所述两个RJ45接口2均设置在电路板1边缘，且两个RJ45接口2的下端均与电路板1下端对齐。The two RJ45 interfaces 2 are both arranged on the edge of the circuit board 1 , and the lower ends of the two RJ45 interfaces 2 are aligned with the lower end of the circuit board 1 .
它还包括用于放置抄表设备的放置架。It also includes a shelf for meter reading equipment.
现在使用时抄表设备上也需要设置一个与RJ45接口匹配的插头，这样就可以直接将插头插入RJ45接口中进行通信且供电了。Now when using the meter reading device, a plug matching the RJ45 interface also needs to be set, so that the plug can be directly inserted into the RJ45 interface for communication and power supply.
