Description
Technical field
The present invention relates to Low Voltage Electrical Apparatus, more specifically to the connector for switch.
Background technology
In the straight-flow system of high working voltage (such as DC1000V or DC1500V) need by the multibreak of multipole switch with
Series system connects, and meets performance needs (such as short circuit, isolation).Usual user can connect multipole switch using cable
Connection, in order to avoid excessive operating temperature, generally requires longer cable.
Occur the offer of partial switch manufacturer in the prior art is connected in series special connector, facilitates showing for user
Field wiring, more scheme is that the switching units of switch are arranged on switch external, also will directly be opened by partial switch manufacturer
The switching units of pass are connected in switch internal, without user's wiring at the scene.But either connected using external dedicated
Connect device wiring or switch internal connects in advance, be required for facing the excessive problem of temperature rise in junction.Asked to tackle temperature rise
Topic, all can be on series connection busbar plus the radiator that piece is prayed dedicated aluminum, it is ensured that control temperature rise more.
For example, Chinese patent CN202268314U discloses a kind of multi-breakpoint direct current type molded case circuit breaker, including with base
The housing of seat, multiple wire connection terminals of short circuit conductor and contact component, multiple wire connection terminals are separately fixed on pedestal, and phase
It is spaced from each other between adjacent line terminals by the partition wall on pedestal, partition wall opens up fluted, short circuit in the end close to wire connection terminal
In conductor insertion groove, and the both ends of short circuit conductor are made to be connected respectively with adjacent wire connection terminal.CN202268314U is used
Be switch switching units switch internal scheme, CN202268314U switch external wiring using metal heat sink drop
Low high temperature rise.
Chinese patent application CN102017039A discloses a kind of breaker, including：Vacuum interrupter, is arranged in vacuum and goes out
The indoor fixed contact jaw of arc and movable contact, fixed contact bar, its vacuum interrupter inner support fix contact jaw and
Stretch out from the first end of vacuum interrupter, mobile contact bar, its movable contact described in vacuum interrupter inner support with
Just move back and forth between fixed contact jaw is contacting and separating and stretch out from the second end of vacuum interrupter, with fixation
The first electric conductor of bar connection, the second electric conductor being connected with mobile contact bar are contacted, and is fixed contact jaw and mobile contact
