Abstract

The invention relates to a contact pin protective device for detection of a wattmeter. The contact pin protective device for detection of the wattmeter comprises a normally closed two-position three-way electromagnetic valve, a two-position five-way air control valve, a normally open two-position three-way electromagnetic valve, a sequence valve and a telescopic air cylinder, wherein the normally closed two-position three-way electromagnetic valve, the two-position five-way air control valve and the telescopic air cylinder are connected in series to form a main circuit, and the normally open two-position three-way electromagnetic valve, the sequence valve, the two-position five-way air control valve and the telescopic air cylinder are connected in series to form an abnormal circuit. The contact pin protective device for detection of the wattmeter resolves the problem that a contact pin is abnormally connected with the wattmeter in a pressing mode in the detection production process of the wattmeter, thereby safely and rapidly realizing appearance detection, voltage resistance detection, verification and other contact pin pressing connecting work for the wattmeter and guaranteeing the efficiency and stability of pressing connecting work.

Description

technical field [0001] The invention relates to a protection device, in particular to a protection device for a detection pin of an electric energy meter. Background technique [0002] At present, in the production line of electric energy meter detection, there is a lack of a method and device for protecting the electric energy meter detection pins in the pin crimping link. It is precisely because of the lack of this kind of device that a large number of pins are bent and broken when the electric energy meter is tested for crimping, and it takes a lot of time to replace it, reducing the safety factor of the staff and other problems, thus affecting the entire electric energy meter. production efficiency. Therefore, it is very necessary to design this electric energy meter detection pin protection device to ensure the efficiency and stability of the crimping operation. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention ai...
