The connector of switch
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
At least one radiator of at least one arrangement in end, wherein radiator are the hollow bodies for including outer surface and inner surface, arrangement
Multiple fins on an internal surface form passage, by channel air with the side parallel with the vibration-direction of mobile contact bar
To convection current.
Chinese patent application CN102945762 discloses a kind of radiator for switching device, including:Copper bar, its
One end is electrically connected to the switching device, and the electric current of switching device is flowed through for conducting;Heat sink, fixed on copper bar, is used for
Radiate to copper bar.
What CN102017039A and CN102945762 was used is all scheme of the switching units in switch external of switch.
CN102017039A and CN102945762 solves the problems, such as high temperature rise using aluminum metal heat sink.
In above-mentioned several schemes, for a user, the busbar of connection and the radiator of heat transmission are two separation
Component, user needs to buy busbar and radiator respectively and is assembled, not good enough in terms of install convenient and economy.Separately
Outside, for switch manufacturers or connection busbar manufacturer, due to busbar generally use U-shaped structure, obtained by punching process, but
Inevitably stock utilization is difficult to maximize, and for noble metal, generally requires more preferably material use
Rate scheme.So can be using stock utilization as preferred Consideration, hence in so that busbar and radiator when busbar manufactures
Connection and the effect of heat dissipation be affected.Also, the production of radiator needs to open the dedicated mould of system, and the mould takes
With for manufacturer be also a cost burden.
