Ammeter wiring terminal

Abstract

The invention relates to the technical field of electrical connection fittings, and discloses an ammeter wiring terminal. The ammeter wiring terminal comprises a wire part, an access part and an insulating protective cover, one end of the wire part is provided with a mounting hole, and the mounting hole is used for crimping an external aluminum wire; the access part is fixedly connected with the other end of the wire part, and the access part is used for being inserted into the access end of an electric meter; and the insulating protective cover is tubular, the insulating protective cover is made of a flexible material, the insulating protective cover comprises a first section and a second section which are communicated with each other, the cross section area of the first section is smaller than that of the second section, the first section is sleeved on the periphery of the wire part, the second section is sleeved on the periphery of the external aluminum wire, and is configured to be capable of being folded and sleeved on the peripheries of the first section and the access part. The ammeter wiring terminal is simple in structure and convenient to use, electric shock accidents or interphase short circuit can be effectively avoided, and the safety performance of an ammeter home-entry line connection point is improved.

Description

technical field [0001] The invention relates to the technical field of electrical connection accessories, in particular to an electric meter terminal. Background technique [0002] The terminal block is to facilitate the connection of wires, which can be disconnected and connected at any time, which is convenient and quick. At the connection of the electric meter connection or the connection end of the user's electricity transmission, the connection is generally fixed by terminal screws. At present, copper-aluminum transition clamps are mainly used for connection points of down-conductor ammeter access terminals or the wires are directly inserted into the wiring holes of the ammeter. Therefore, copper-aluminum transition terminals often heat up severely or even burn out, and loose strands of wires or loose screws lead to poor contact. And cause the undesirable phenomenon that connecting point burns; And when ammeter is overhauled, terminal head is exposed outside, easily ca...

Problems solved by technology

At present, copper-aluminum transition clamps are mainly used for connection points of down-conductor ammeter access terminals or the wires are directly inserted into the wiring holes of the ammeter. Therefore, copper-aluminum transition terminals often heat up severely or even burn out, and lead wires are loose or screws are loose, resulting in poor contact. And cause the unfavorable phenomenon that the connection point is burned; and when the ammeter is overhauled, the head of the terminal is exposed, which is likely to cause electric shock accidents or phase-to-phase short circuits.

The above problems have had a great impact on the stability and reliability of residents' electricity consumption, and have seriously affected the normal life of residents.
