Description

Ground wire binding post capable of preventing stranded wire from falling off Technical Field The utility model relates to the technical field of ground wire connecting terminals, in particular to a ground wire connecting terminal capable of preventing stranded wires from falling off. Background In electroengineering, terminals are multi-finger wire terminals, also known as terminals, are classified as single hole, double hole, socket, hook, etc., from materials, copper silver plating, copper zinc plating, copper, aluminum, iron, etc. Their function is mainly to transmit electrical signals or to conduct electricity. At present, aluminum, iron and the like are generally adopted for the ground wire connecting terminal connected with the stranded wire, one type of the ground wire connecting terminal connected with the stranded wire adopts a pressure device to tightly press the sleeve part so as to clamp the stranded wire, and the other type of the ground wire connecting terminal adopts a bolt to tightly press the stranded wire so as to avoid the stranded wire from being separated, but the stranded wire and the connecting terminal are still easy to separate in the connecting mode, so that an improved technology is needed to solve the problem in the prior art. Disclosure of utility model The utility model aims to provide a ground wire connecting terminal for preventing stranded wires from falling off, so as to solve the problems in the prior art. The ground wire connecting terminal comprises a connecting terminal body, an arc-shaped pressing plate and a bolt, wherein the connecting terminal body comprises a fixing plate and a sleeve, one end of the sleeve is provided with the fixing plate, the sleeve is axially provided with a wire inserting cavity, one end of the wire inserting cavity, far away from the fixing plate, is open, the top end of the sleeve, which is positioned at the wire inserting cavity, is provided with an extension groove, the sleeve, which is positioned at the open position, is provided with a baffle plate at the outer end of the extension groove, the upper part of the sleeve is penetrated and provided with a screw hole, the screw hole is communicated with the wire inserting cavity, the bolt is matched with the screw hole, the arc-shaped pressing plate is movably arranged in the extension groove and the wire inserting cavity, the lower surface of the arc-shaped pressing plate is provided with a plurality of triangular barbs, and the upper surface of the arc-shaped pressing plate is matched with the bolt. Preferably, the utility model provides a ground wire connecting terminal for preventing a stranded wire from falling off, wherein a thickened connecting section is arranged at the joint of a sleeve and a fixed plate. Preferably, the utility model provides a ground wire connecting terminal for preventing a stranded wire from falling off, wherein a plurality of fixing holes are formed in a fixing plate. Preferably, the utility model provides a ground wire connecting terminal for preventing stranded wires from falling off, wherein one end of a wire insertion cavity, which is far away from a fixed plate, is provided with a chamfer. Preferably, the end, close to the fixing plate, of the triangular barb is a vertical plane, and the end, far away from the fixing plate, of the triangular barb is an inclined plane. Compared with the prior art, the utility model has the beneficial effects that: The extension groove has been seted up to the upper end in the inside plug wire chamber of sleeve, and the outer end in extension groove is provided with keeps off the platform, screw and bolt cooperation have been seted up on the sleeve top, telescopic plug wire intracavity is through arc clamp plate cooperation, when the stranded conductor inserts telescopic plug wire intracavity, push down the arc clamp plate through the bolt, arc clamp plate inboard surface is through triangle barb suppression stranded conductor, thereby avoid the stranded conductor to break away from in the sleeve, keep off the platform through the extension groove outer end, can avoid the arc clamp plate to break away from plug wire intracavity, and then make the stranded conductor be difficult for breaking away from with the sleeve.
