Straight-through type current transformer wiring terminal and alternating current board

Abstract

The invention discloses a straight-through type current transformer wiring terminal which is stable in electric connecting performance and simple in production process and can improve installing efficiency and an alternating current board. The alternating current board comprises a circuit board (8), the straight-through type current transformer wiring terminal fixedly arranged on the circuit board (8) and a plurality of straight-through type current transformers (9). The straight-through type current transformer wiring terminal further comprises at least one first terminal plughole (2), at least one second terminal plughole (3), first lock nuts (4) and second lock nuts (5), wherein the at least one first terminal plughole (2) and the at least one second terminal plughole (3) are arranged on the same side (10) of a terminal base (1), the first lock nuts (4) are arranged on the side (11) adjacent to the side (10) to be used for pressing wires in the first terminal plugholes (2), and the second lock nuts (5) are arranged on the side (12) adjacent to the side (10) to be used for pressing wires in the second terminal plugholes (3). Two ends of current carrying wires of the plurality of straight-through type current transformers (9) are respectively arranged in the first terminal plugholes (2) and the second terminal plugholes (3).

Description

technical field [0001] The invention relates to a connection terminal and an AC board for a through-core current transformer. Background technique [0002] Terminal block is an accessory product used to realize electrical connection, which is industrially divided into the category of connectors. With the increasing degree of industrial automation and stricter and more precise industrial control requirements, the amount of terminal blocks is gradually increasing. In addition to PCB board terminals, the most widely used ones are hardware terminals, nut terminals, spring terminals, etc. Wait. At present, on the AC board of the microcomputer device, it is necessary to electrically connect the two ends of the current-carrying wire of the feed-through current transformer through the terminal.

Problems solved by technology

At present, on the AC board of the microcomputer device, it is necessary to electrically connect the two ends of the current-carrying wire of the feed-through current transformer through the terminal. The locking screw on the same side of the seat, when installing the current-carrying wire, unscrew the locking nut first, then rely on the installer to make a ring-shaped wire lug at the end of the current-carrying wire, insert one end and then tighten the locking nut, and Insert the other end through the feed-through current transformer and then tighten the lock nut, and it is easy to loosen due to the irregular wiring of the installer, which makes the connection between the outgoing line of the current transformer and the terminal unreliable. It is even necessary to ensure the stability of the electrical connection by means of welding on this basis, which not only complicates the process, but also reduces production efficiency
