Lightly pluggable contact combination module

Abstract

The invention relates to a contact type combined module convenient to plug and pull out. The contact type combined module convenient to plug and pull out comprises a base, an upper cover and a connecting contact used for being plugged into a jack of an electric energy meter. An inner core is arranged inside the connecting contact. A wedge mechanism is arranged in the combined assembly. The wedge mechanism rotates to drive the part, inserted into the inner core, of the wedge mechanism to move front and back, then the inner core can move in the axial direction, and a leaf spring at the exposed end of the connecting contact is tensioned or released. The contact type combined module convenient to plug and pull out overcomes the defects of a traditional plugging and pulling module, the human body direct contact adjusting mode such as manual tearing and manual rotating is abandoned, the connecting contact can be in tensioned or released connection with the jack of the electric energy meter only through the mode of adjusting a threaded sleeve by a screwdriver, plugging and pulling force is not required, an electric appliance can be mounted on spot rapidly, conveniently, safely and firmly, manufacturing is convenient, and the service life is long.

Description

technical field [0001] The invention relates to a lightly pluggable contact type combination module. Background technique [0002] At present, the State Grid clearly stipulates that "the installation and electrical connection of electric energy meters should be realized through special connectors for electric energy meters, and the wires must not be directly connected to electric energy meters. Safe and secure installation features". However, due to the large deviation between the hole diameter and the hole distance of the socket holes used for the connection of a large number of watt-hour meters, the use of simple spring sleeves and interference fit connections will cause excessive insertion and withdrawal force, and the repair and maintenance need to adjust the shrapnel When the deformation range can only be broken by hand, it is not only difficult to adjust the position, but also very troublesome and easy to get an electric shock. It cannot realize the "fast, convenient,...

Problems solved by technology

However, due to the large deviation between the hole diameter and the hole distance of a large number of socket holes used for connection of electric meters, the use of simple spring sleeves and interference fit connections will cause excessive insertion and withdrawal force, and the repair and maintenance need to adjust the shrapnel When the deformation range can only be broken by hand, it is not only difficult to adjust the position, but also very troublesome and easy to get an electric shock. It cannot realize the "fast, convenient, safe and reliable installation function of the electric energy meter", and the manufacturing requirements are high and the service life is short, so it needs to be improved.
