Technical field
The utility model relates to conductor terminal, relates in particular to a kind of terminal structure that enamelled wire connects that is used for
Background technology
Have the thread winding of enamel-cover in the equipment such as large power reactor, inductance, motor.In the prior art, the terminal of each winding often is connected with outer lead by the mode of terminal compacting.At big electric current, under the powerful operational environment, when many enamelled wires are suppressed and welded, be sealing because terminal is inner, so tend to occur rosin joint, leak problems of welded quality such as weldering.Because still there is the space in the mode of compacting terminal, can't avoid taking place electrical erosion in running, the loosening of impedance increase and terminal can't be avoided fully.Add the influence that is subjected to dither for a long time, joint easily gets loose, and causes impedance to strengthen, operation heating, energy consumption rising or the like adverse effect.
Present many companies often use aluminum steel to replace copper cash for reducing cost, and coil windings is used aluminium, and outer lead uses copper material, has so just brought new problem.Because the difficulty of aluminum steel welding is bigger, easy oxidation during welding, poor welding quality often appears in the mode that adopts traditional terminal compacting to weld, the phenomenon that impedance is bigger, this phenomenon is particularly evident at multiply aluminum conductor (＞4 strands).Copper is two kinds of different metals with aluminium, they is simply linked together electrochemical reaction can take place.Time is long slightly, and the junction contact resistance can increase, generate heat, and causes the circuit switch-on and-off, and voltage is fluctuated, even causes fire.Common solution is: by copper and aluminium welding tin silk, multiply copper core cable and aluminum steel are welded to connect, still can there be the impedance condition with higher in such processing, and copper aluminium directly contacts and be exposed in the air, can have the risk of couple corrosion.
Summary of the invention
The utility model is will solve in the prior art enamelled wire to draw the bigger problem of the not firm impedance of wiring, proposes the low Wiring terminal of enameled wire of the firm impedance of a kind of wiring.
For solving the problems of the technologies described above, the technical scheme that the utility model proposes is a kind of Wiring terminal of enameled wire of design, and it comprises: insulation board, be separately fixed at the pair of conductive row at insulation board two ends; Described busbar one end is provided with the wire bonds hole in order to the welding outer lead, and the busbar other end is provided with at least one enamelled wire welding hole in order to the welding enamelled wire.
Only weld an enamelled wire in the described enamelled wire welding hole, the quantity of enamelled wire welding hole is corresponding mutually with the radical of the enamelled wire that needs welding.
In one embodiment, described busbar level is installed; Described insulation board is made as recess step in the place that contacts with busbar, and the shape of this recess step conforms to busbar.Described busbar is provided with screw through-hole in the place corresponding with recess step, and fixed screw passes screw through-hole busbar is fixed on the insulation board.Scribble screw thread fastening glue between described fixed screw and the insulation board.
In another embodiment, the edge-on installation of described busbar; Described insulation board is made as recess step in the place that contacts with busbar, and the shape of this recess step conforms to busbar.Described busbar is provided with screw through-hole in the place corresponding with recess step, and fixed screw passes screw through-hole busbar is fixed on the insulation board.Scribble screw thread fastening glue between described fixed screw and the insulation board.
At different fields of employment, above-mentioned busbar can adopt copper bar also can adopt aluminium row, can also adopt copper-aluminium transition row.When adopting copper-aluminium transition row, it is a copper material at the end near the wire bonds hole, and it is an aluminium at the end near the enamelled wire welding hole.
Compared with prior art, the utlity model has tangible Low ESR.According to the solder stick physical characteristic that solder stick supplier provides, the tensile strength of general pad is greater than 2000N.And solder joint air-isolation, can after long-time running, still keep good electric property and stability, especially be fit to use be operated at high-frequency inverter etc. high-power, high-frequency multiconductor electric device (for example many windings reactor), the energy long-term work does not get loose under the situation of high-frequency vibration and keeps the integraty of terminal, the terminal structure secure and reliable connection has avoided terminal to be out of shape the possibility that causes direct contact the in winding two ends and be short-circuited.
