Description
Technical field
The present invention relates to a kind of circuit breaker, especially a kind of lead can insert the fast-wiring formula circuit breaker of junction block fast.
Background technology
The binding post of existing circuit breaker generally includes terminal screw and wire frame; Terminal block passes in the wire frame, and terminal screw connects on the wire frame, and terminal screw is against the terminal block upper side; Lead is arranged in the wire frame of terminal block downside; Move through turning terminal screw, making on the wire frame, with lead fixed between wire frame and terminal block.This circuit breaker must be tightened terminal screw with screwdriver when connecting, the lead of insertion is fixedly connected with binding post, installs more loaded down with trivial details.
The circuit breaker that rapid plug-in is also arranged on the existing market; The conductor that its binding post is designed to suitable special construction directly inserts connection; But owing to can only use a kind of conductor of structure to insert connection fast; Want in use earlier lead to be connected with the conductor of this structure, still very inconvenient, and also wide usage is not high.
Summary of the invention
For above-mentioned reasons, the object of the present invention is to provide a kind of can directly lead the insertion fast to connect and circuit breaker easy and simple to handle.
For realizing above-mentioned purpose, the present invention adopts a kind of fast-wiring formula circuit breaker, comprises housing, binding post, handle, operating mechanism, electromagnetic assembly, thermal cutoff assembly, arc-extinguish chamber; The binding post of circuit breaker one end comprises reed, sliding part, terminal block, and terminal block is arranged on the end in the housing, and the downside of terminal block is corresponding with the wiring hole of housing; The reed two ends are respectively stiff end and link, and stiff end is stuck in the housing medial surface, conflict on terminal block in link is oblique; The link of reed forms the reed wing to the both sides protrusion; Sliding part is arranged in the housing, forms the saddle hole on the housing of sliding part upper end, and the lower end of sliding part forms and two suitable saddle pin of the reed wing; Terminal block passes between the saddle pin, and two saddle pin are against respectively on two reed wings.
The present invention's lead when connecting can directly insert from wiring hole, is stuck between terminal block and the reed; Only need press sliding part in the time of lead need being extracted with the object of convexity; Because the saddle pin of sliding part and the reed wing on the reed are conflicted; Thereby sliding part overstocks reed and moves down the crack that makes between reed and the terminal block and become big moving down to make, and lead is loosening can extract lead.
The saddle pin that the invention has the beneficial effects as follows the reed wing that is provided with on the reed and sliding part is conflicted, and the saddle pin is crossed on the terminal block both sides, and sliding part does not move down can be influenced by the butted line plate to some extent, but can the actuating spring wing, and the link of reed is bent downwards.Because the reed wing is arranged on the link both sides of reed, the position is near the top, and is bigger to the displacement of reed wing stress point from the rotating fulcrum of reed, only needs less power just can make the reed motion, makes things convenient for lead to extract.
The present invention further is set to two wiring holes of corresponding terminal block downside formation on the said housing, offers a finedraw in the middle of the link of reed, reed is divided into two at link, respectively two wiring holes of corresponding housing.Two wiring holes insert two leads, block lead respectively through the reed that separates, and guarantee the contact area of lead, guarantee that the electric current that passes through is enough big.
The both sides that the present invention further is set to said sliding part form draw runner, and the housing medial surface forms the suitable chute of draw runner with sliding part.Draw runner with make the motion of sliding part in housing more smooth and easy cooperating of chute.
Operating mechanism of the present invention comprises contact supporting, reel cage, snap close, tripping, moving contact, and moving contact is arranged on the contact supporting, and reel cage is hinged with contact supporting and snap close respectively, and tripping is arranged in the reel cage; Be formed centrally the tripping hole in the tripping, the outside one end forms the button frame, and the other end forms push pedal; Form the reel cage groove on the reel cage, the button frame is buckled in the reel cage groove, and push pedal withstands on the snap close; Tripping and handle are connected through the U-shaped pin, and U-shaped pin one end is inserted in the tripping hole, and an end is inserted on the handle.This operating mechanism is fairly simple and reliability is high.
The opposite side of circuit breaker of the present invention is provided with the bus-bar terminal; Comprise wire frame and U type reed, wire frame one side opening, the wire frame opening is arranged in the housing toward the outer side; The position of the corresponding wire frame of housing is provided with the bus-bar connection jaws, and U type reed opening is stuck in the wire frame inwardly.The opposite side of circuit breaker adopts the bus-bar wiring, and U type jump ring is stuck in the bus-bar that inserts on the wire frame upper inside walls.
The downside that the present invention further is set to said wire frame forms a bayonet socket; The downside top of U type reed forms a spacing preiection adaptive with the bayonet socket width; The downside of U type reed is offered fastener; The inside side of fastener keeps being connected with U type reed, and the downward perk of opposite side is stuck in the wire frame through making fastener and cooperating of bayonet socket U type reed.U type bus-bar can easily insert in the wire frame through the fastener of perk, is fixed in the wire frame with bayonet fittings on the wire frame.
