Description
Technical Field
The invention belongs to the field of electrical elements, and particularly relates to an anti-loosening wiring terminal, in particular to an anti-loosening wiring terminal used on a socket.
Background
In an electrical system, the most common connection terminal is used for connecting a circuit, the common connection terminal on a socket is generally a socket reed connecting wire, the existing connection mode is that a connecting sheet is generally arranged on a reed and is externally provided with a connecting seat with a screw hole, the connecting sheet is inserted into the connecting seat and then is fixed on the connecting seat through a screw, and a wire is welded on the screw and is wound on the screw along with the rotation of the screw to realize fixation, so that the welding point of the wire and the screw is prevented from falling off.
In the long-term use process, the lead is inevitably pulled, the lead provides a force for unscrewing the screw, and the screw is loosened more and more in the past, and finally the connecting sheet is in poor contact with the connecting seat and even separated from the connecting seat.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides the anti-loosening wiring terminal which can effectively prevent a screw from loosening in the process of pulling a lead, thereby effectively preventing poor contact between a connecting sheet and a connecting seat and prolonging the service life.
In order to solve the technical problem, the invention is solved by the following technical scheme: the utility model provides an anti-loosening wiring terminal, includes reed, connecting seat and screw, be provided with on the reed and insert the connection piece of connecting seat, the screw middle part is provided with the wire winding through-hole, wire winding through-hole both sides are provided with vertical spout, be provided with the sliding block in the spout, be provided with the pivot on the sliding block, be provided with the wrapping post in the wire winding through-hole, the middle part of wrapping post is provided with the ring channel, the ring channel both sides card is equipped with the pivot, the wrapping post upper end is provided with the arch, the screw bottom be provided with protruding complex recess, be provided with the spring between wrapping post and the wire winding through-hole bottom, the wrapping post periphery still is provided with the wire winding groove on the wrapping post wire winding groove place. According to the anti-loosening wiring terminal, the connecting seat is sleeved on the connecting sheet during wiring, then the screw is screwed into the screw hole to fix the connecting seat and the connecting sheet, then the wire penetrates through the wire positioning through hole and is welded, then the wire is wound on the winding post through the rotating winding post in the direction opposite to the screwing direction of the screw, and then the spring is arranged between the connecting sheet and the winding post, so that the protrusion is inserted into the groove to be matched, and the installation is completed. In the subsequent use, if the wire is pulled, the rotating force borne by the screw faces to the direction of screwing the screw, so that the screw is effectively prevented from loosening and the connecting sheet and the connecting seat are prevented from poor contact, and the service life of the anti-loosening connecting terminal is prolonged.
In the above technical scheme, preferably, the connecting seat and the connecting piece are both provided with cutting marks. Adopt this structure to make the frictional force increase between connecting seat and the connection piece, guarantee the stability of contact.
In the above technical scheme, preferably, the connecting seat is matched with the connecting sheet in shape. By adopting the structure, the contact surface between the connecting seat and the connecting sheet is larger.
In the above technical solution, preferably, the winding post is provided at the periphery thereof with a protruding strip for shifting the winding post to rotate. By adopting the structure, the wire can be more conveniently rotated when being wound on the winding post.
Compared with the prior art, the invention has the following beneficial effects: this kind of locking binding post that moves can effectively prevent to become loose at the in-process screw that the wire was dragged to effectively prevent connection piece and connecting seat contact failure, improve life.
