Description
Technical Field
The invention relates to the technical field of low-voltage switches, in particular to a tight-loop low-voltage switch wiring terminal.
Background
The low-voltage switches (residual current operated protectors, circuit breakers, isolators, external circuit breakers of the electric meter and the like) used by low-voltage electricity customers are widely applied, and the shadows of the low-voltage switches are formed in places almost using electricity from the isolators and the circuit breakers in front of the electric meter to the residual current operated protectors (leakage switches) to the indoor branch switches; according to actual requirements, the low-voltage switches are various, the installation modes and positions are different, and the effects are also different; the safe and normal use of the low-voltage switch has great influence on the electricity utilization safety and fire safety of electricity customers, but the low-voltage switch still has more faults due to factors such as product quality, installation process, operating environment and the like.
Common low-voltage switch input on the existing market, output binding post adopts the single clamp plate, the single bolt is fixed, but the cover is equipped with on the clamp plate and supplies the stub to insert the lantern ring, the groove personnel are when installation low-voltage switch, will insert the stub between lantern ring inside wall and the clamp plate earlier, let clamp plate and lantern ring inside wall extrusion stub through the single bolt, thereby fix the stub at switch output and input section, current low-voltage switch fault point mainly concentrates on the switch input, output binding post, the analysis reason is contact failure between wire and binding post mainly, cause contact failure's reason to have following several aspects: the installation process is poor, and the bolt is not fastened; a multi-core aluminum wire (multi-core copper wire) is used for connecting a wiring terminal, and the multi-core wire is easy to loose strands to cause poor contact because wiring equipment such as a wire nose and the like is not used; copper and aluminum are oxidized, the wire is an aluminum core wire, the connecting terminal is copper, and poor contact is caused by copper and aluminum oxidation; the insulation layer of the insulated wire is not peeled enough, the insulation layer is pressed in the wiring terminal, and the wire is not in good contact with the wiring terminal; the wire end of a wire is not processed well to form a protruding surface, and because the wiring terminal is a single bolt and a single pressing plate, the pressing plate and the wire protruding surface are easily compressed, but the contact surface is small to cause poor contact, the wiring terminal is short, the contact surface is insufficient to cause poor contact, the single-point crimping is adopted, the crimping is not fastened, and the loosening is easy.
The above prior art solutions have the following drawbacks: the clamp plate is shorter and flat, the lantern ring lateral wall is also the plane, the connector lug inserts between clamp plate and the lantern ring, need lean on the position of clamp plate and the mutual extrusion of lantern ring to fix the connector lug, but the connector lug is the multicore wire generally, in case the connector lug is extruded and must disperse to both sides, lead to between clamp plate and the lantern ring the space more, and in case there is comparatively hard foreign matter between clamp plate and the lantern ring, for example, there is the clearance between insulating layer or the clamp plate of connector lug and the lantern ring, must lead to having the clearance between clamp plate and the lantern ring, thereby lead to the unable quilt of wire barrel to be compacted, and the dispersed connector lug that comes can leak the clamp plate even, this problem is urgent to be solved.
Disclosure of Invention
The invention aims to provide a tight-hooping low-voltage switch wiring terminal which has the function of improving the connection stability of a wiring terminal and a low-voltage switch.
