Wiring terminal for preventing screw from falling off and wire holder thereof

Abstract

The invention relates to the field of electrical connection products, in particular to a wiring terminal for preventing a screw from falling off and a wire holder thereof. The wiring terminal provided by the invention comprises a base with a through hole, a thread fixing hole formed on the base, a thread fixing piece matched with the thread fixing hole, and a conductive piece arranged on the thread fixing piece by penetration, wherein the conductive piece is provided with a pin penetrating through the through hole; a screw hole part matched with the thread fixing piece is arranged in the thread fixing hole; the base is provided with a semi-enclosed separator; and a top cover is arranged at the top end of the separator. The wiring terminal provided by the invention is provided with the top cover which can prevent a loose screw on the wiring terminal from falling onto the electrical equipment so as to prevent the short circuit of the electrical equipment, and the structure of the screw does not need to be damaged, thus the wiring terminal can be rewired only by screwing the screw; and because a stamping station does not need to be reserved, the whole volume is greatly reduced.

[0002]Terminal is a common component for electrical connection, which is widely used in various electrical equipment, and the electrical equipment generally contains magnetic parts. Such as: transformer; therefore, if the screw in the terminal is loosened from its base, it will be attracted by the magnetic parts in the electrical equipment and fall onto the electrical equipment, which will easily cause a short circuit of the electrical equipment and damage the electrical equipment. cause damage; for this reason, preventing the screw from falling off has become an important technical problem, and the existing technology generally uses mechanical stamping to stamp the tightened screw so that the screw and the nut are combined to prevent falling off. effect; however, in the existing technical means, it destroys the structure of the screw, and when the terminal needs to be rewired, the screw cannot be unscrewed from the nut, and it needs to replace the terminal as a whole. It makes the cost high; and it needs to reserve a station for stamping, which greatly increases the volume and production cost of the entire terminal block
