Problems solved by technology

However, on the one hand, if these mounting bases are loosely matched, it is easy to cause poor contact. If the plugging fit with the electric energy meter is too tight, the electric meter is difficult to pull out, and it is inconvenient to replace the electric meter or repair the electric meter.

Embodiment Construction

[0015] From figure 1 As can be seen from the overall structure of the present invention, the present invention mainly includes an electric plug 1, a slider seat 2, a mounting seat 3, a rear fixing seat 4, a switch 5, and a back plate 6, wherein the slider seat 2 is located at the mounting seat 3 and the rear fixing seat Between the seats 4, and can slide back and forth in this space, the forward direction of the slider seat 2 is limited by the mounting seat, and the backward direction is limited by the rear fixed seat 4.

[0016] figure 2 It reflects the structure of the electric plug, and also reflects the installation relationship between the electric plug and other components. It can be seen from the figure that the electric plug 1 is mainly composed of a thimble 11, an elastic member 12, and a split-type plug-in 13. The thimble 11 is located in the split insert 13 , the tail of the thimble 11 is installed in the slider seat 2 , the front end of the elastic member 12 bea...

Abstract

The invention discloses a plug-in type terminal seat, which includes an electric plug plugged with a terminal of an electric energy meter, and a mounting seat of the electric plug. The electric plug mainly consists of a thimble, an elastic member, a split type Plug-in components, the thimble is inserted into the split-type plug-in and can move in it, the driving force of the thimble forward comes from the elastic member, and the movement of the thimble changes the opening angle of the split-type plug-in, which is used to ensure that the electrical plug is compatible with the electric energy. Good contact with the meter terminal holes. On the one hand, the invention can ensure the stable insertion of the electric plug and the electric energy meter, and on the other hand, can easily take out the electric energy meter. Realize fast plug-in connection between energy meter and power line.

Description

technical field [0001] The invention relates to a plug-in terminal block used when an electric energy meter is connected with a power line. Background technique [0002] The energy meter needs to be directly connected to the power line through screws during installation. On the one hand, the site workload is large, and it is easy to connect the wrong wire, the screw is not tightened, and the connection is not reliable, resulting in large contact resistance and low current conductivity. Heat is generated at the connection, and at the same time, the bare copper wire inside the power supply wire and the insulation layer outside the wire are damaged to a large extent. On the other hand, it is inconvenient to replace the ammeter or maintain the ammeter. In the information disclosed by the Chinese patent, some mounts for installing electric meters are published. When this type of mounting base is used, the terminal is first connected to the power line. When the meter is installed...
