Description
Technical field
A kind of low-voltage electrical apparatus is the utility model is related to, specially a kind of miniature circuit breaker.
Background technology
Conventional small breaker is as shown in figure 1, its structure includes：Operating mechanism, tripping mechanism, contact machine in housing
Structure, electromagnetic system and arc-control device, the operating mechanism include handle, and the tripping mechanism includes tripping, lock, the contact
Mechanism includes dynamic contact mechanism, static contact mechanism, and the electromagnetic system includes magnet coil, and the arc-control device includes arc extinguishing
Room, the handle connect tripping by connecting rod, and described magnet coil one end is connected with binding post, the other end and static contact mechanism connect
Connect, the dynamic contact mechanism connects the double gold plaques of heat by flexible wire, sets thermal tripping to draw between the lock and the double gold plaques of heat
Bar.
125 amperes of miniature circuit breaker temperature rise of existing 18mm moduluses is difficult to meet national standard in the market, reason
It is：Original design moving contact part be feeler lever type, and it is less than normal that feeler lever type welds the lead location that is flexible coupling, and increases product internal resistance, makes
Internal temperature rise is higher, easily occurs being flexible coupling and the viscous glutinous phenomenon of shell.In addition, use a flexibility between moving contact and the double gold plaques of heat
Wire connects, and is further exacerbated by problem of temperature rise.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of miniature circuit breaker for reducing temperature rise.
To solve the above problems, the technical solution adopted in the utility model includes operating mechanism, the dropout being located in housing
Mechanism, contact mechanism, electromagnetic system and arc-control device, the operating mechanism include handle, and the tripping mechanism includes tripping, lock
Button, the contact mechanism include moving contact, static contact, and the electromagnetic system includes magnet coil, and the arc-control device includes going out
Arc chamber, the handle are connected by connecting rod with tripping, and described magnet coil one end is connected with binding post, the other end and static contact connect
Connect, the moving contact connects the double gold plaques of heat by flexible wire, it is characterised in that：The moving contact side is provided with an angle
The solder side of downward bending, the solder side lower surface are welded with two flexible wires, the other end of two flexible wires
Welded respectively with hot double gold plaques and arc striking piece.
Described miniature circuit breaker, it is characterised in that：The first connection sheet, the is respectively welded in the double gold plaque two bottom sides of heat
Two connection sheets, the first connection sheet upper end and wiring plate weld, the arc striking piece, flexible wire are respectively welded to be connected in described two
Contact pin upper end both sides.
Miniature circuit breaker advantage of the present utility model is as follows：Designed by the solder side of bending, make the wire welding that is flexible coupling
Face, which lengthens, to be increased, and increases solder side, is reduced product internal resistance and is effectively prevented that temperature rise is higher.In addition, point for passing through double-flexibility wire
Stream design, can further reduce product internal resistance, further to reduce temperature rise.
