Abstract

The invention relates to a socket and a connector including the same. The connector is used for being connected with a current transformer and comprises the socket and a plug, the socket is used for being electrically connected with current transformer secondary terminals, the plug is matched with the socket, a plurality of contact pins and a contact pin fixing plate are arranged in the socket, the contact pins are used for being connected with current transformer secondary currents, each contact pin comprises a root portion and a head portion connected with the root portion, the diameter of each head portion is larger than that of each root portion, each root portion is sleeved with an insulation sleeve, each insulation sleeve is sleeved with a spring, short contact pieces are arranged among the contact pins in a sleeved mode, the root portions of the contact pins used for being connected with the current transformer secondary currents are sleeved with the short contact pieces, the short contact pieces are located at the ends, adjacent to the head portions, of the root portions, one end of each spring abuts against the contact pin fixing plate, and the other end of each spring abuts against the corresponding short contact piece. The connector can always avoid current connector secondary open circuit, well guarantees installation and debugging safety of the current transformer, and is simple and reliable in structure, easy to manufacture, low in cost, safe and reliable.

Description

technical field

[0001] The invention relates to the field of electrical technology, in particular to a socket used in electric equipment and a connector with the socket. Background technique

[0002] In the distribution automation system, the switch on the column mainly uses the current transformer as one of the important components for detecting the line current and ground fault. During the operation of the line, the current transformer (CT) detects the The current signal is transmitted to the controller (feeder terminal) for measurement, calculation and processing. When the existing pole-mounted switch is connected to the controller, when the socket of the connector is separated from the plug, an open circuit is formed between the current secondary terminals of the current transformer of the switch body to generate high voltage, which endangers the safety of people and equipment. Often in the actual construction process, the switch body on the pole and the control box are...
