Background technology
In the interconnection of electronic circuit, power connector is requisite components and parts in the power circuit interconnection system.The contact terminal of relative transmission signals; The design that is applied to the big electric current contact terminal in the power connector is very crucial, because contact terminal is in the process of the big electric current of transmission, if contact resistance is bigger; Can produce more heat; When these heats can't be in time, when distributing effectively, will produce very high temperature at regional area, cause the electrical property of power circuit to change.Therefore how to reduce conductor resistance, increasing heat radiation is big electric current connected system key for design, and it will directly influence the final performance of whole transmission circuit.
In power connector; Its contact exists very big difference with respect to signal contacting piece, and the power supply contact need have higher requirement, and it not only will have very low contact resistance, bigger contact area, area of dissipation; And when the power supply contact is assembled in the insulating base; Good heat radiation, ventilation condition are arranged, and then satisfy heat minimizing and temperature rise control in the big current delivery process, reduce because big current delivery produces higher temperature rise to the electronic circuit Effect on Performance.Yet it is little that plug of power connector of the prior art exists contact area, and resistance is big, the shortcoming of weak heat-dissipating, and especially temperature rise is higher in big current delivery process, has had a strong impact on circuit performance, and complex structure, and assembly technology is loaded down with trivial details, and manufacturing cost is high.
Summary of the invention
A kind of large current interruption device combined socket and switch that the objective of the invention is to be directed against the deficiency of prior art and design; It adopts the socket of killer switch to realize that the power supply of big electric current connects; That satisfies switch when plug lets out the electric arc requirement, has higher reliability, and can fool proof; Perfect heat-dissipating has been improved the circuit performance of big current delivery greatly.
The objective of the invention is to realize like this: a kind of large current interruption device combined socket and switch; Comprise the tie breaker of forming by socket and switch; Be characterized in that socket is that a side is provided with the rectangular insulator that A lets out the electric arc groove, the one of which end is provided with jack, and the other end is provided with A slot and B slot; Grafting A contact on the A slot, grafting B contact on the B slot; Switch is the rectangle blind plug that an end is provided with C contact and D contact, and the one of which side is provided with B and lets out the electric arc groove; The switch socket joint is in the jack of socket, and C contact and D contact are pegged graft with A contact and B contact respectively and realized that the conducting of big electric current, its A let out electric arc groove and B and let out the electric arc groove and be superimposed as circuit breaker and let out the electric arc hole.
Said A contact is the shell fragment that is provided with A contact jaw, zigzag A leg and is used to locate, and the A contact jaw is that socket and spigot type and zigzag A leg are the right angle setting.
Said B contact is the bayonet socket that is provided with B contact jaw, zigzag B leg, louvre and is used to locate, and the B contact jaw is that socket and spigot type and zigzag B leg are the right angle setting.
Said rectangular insulator is provided with the plush copper of several radiating grooves, gathering sill and location.
Said A slot and B slot are provided with locating piece.
The present invention compared with prior art has higher reliability; That satisfies switch when plug lets out the electric arc requirement, can fool proof, and perfect heat-dissipating; Solved the connectivity problem of killer switch and pcb board; Improved the circuit performance of big current delivery greatly, and simple for assembly process, be user-friendly to.
