Embodiment Construction

[0014] Referring to the attached picture:

[0015] The connection column 1 with an elastic metal sleeve according to the present invention is characterized in that it includes a cylindrical conductive shaft 11, and an elastic metal sleeve 12 is covered on the shaft 11, and the outer middle part of the metal sleeve 12 is The drum and the end are sleeved on the shaft 11; at least one of the metal sleeves 12 is matched with the conductive round hole of the circuit board, and at least one of the metal sleeves is matched with the conductive round hole of the wire terminal. The outer diameter of the middle part of the metal sleeve 12 is smaller than the inner diameter of the circular hole.

[0016] The end of the metal sleeve 12 is connected to the shaft shoulder 13 of the shaft.

[0017] After one end of the present invention is pressed into the terminal 31 of the terminal button 3 of the ammeter, the circuit board 2 is pressed into the other end of the terminal, and the conductiv...

Abstract

A connecting column with elastic metal sleeves comprises a cylindrical electroconductive shaft, the elastic metal sleeves are sleeved on the shaft, the middle of each metal sleeve plumps outwards, and the end of each metal sleeve is sleeved on the shaft. At least one of the metal sleeves is matched with a round electroconductive hole of a circuit board, at least one of the metal sleeves is matched with a round electroconductive hole of a connection terminal, and the external diameter of the middle of each metal sleeve is larger than the internal diameter of the corresponding round hole. The circuit board of an electric energy meter can be connected with the connecting column rapidly and reliably.

Description

Technical field [0001] The invention relates to a connecting column with an elastic metal sleeve, in particular, it is suitable for the connecting piece between the circuit board and the connecting terminal on the intelligent electric energy meter. Background technique [0002] At present, the connection between the terminal and the circuit board on the smart energy meter is generally connected by a wire, that is, one end of the wire is welded to the circuit board, and the other end is fixed on the terminal with screws to complete the connection between the terminal and the circuit board. This kind of strip wire connection needs welding or screwing, because the number of connecting wires is large and the wires are long, not only will a magnetic field affect the electronic components after power is applied, but also it is very likely that the wrong wire position will be connected. Welding or screw connections may produce virtual connections, which are cumbersome to detect. T...
