Abstract
The utility model discloses a communicator, which comprises a hook welded to varnished wire of a rotor winding, and a tin layer connected to inner and outer walls of the hook and connecting parts of the hook and the varnished wire. An insulating layer of the varnished wire is pulled off by adjusting parameters of a spot welding machine such as temperature, pressure, etc., as the tin layer tin layer is connected to inner and external walls of the hook and connecting parts of the hook and the varnished wire, and the tin layer, the varnished wire, and the hook are melted into an integer under the action of temperature to increase contact area thereof, stabilize welding, reduce internal resistance in the connection position, and greatly increase electrical conductivity.
Description
Technical field
The utility model relates to a kind of commutator (commutator), is mainly used on the rotor of direct current machine or alternating current machine.
Background technology
Hook is the important component part of commutator, and the welding position of the enamelled wire of hook and epitrochanterian winding is most important, is directly connected to motor properties, the moment of torsion that is produced and useful life.Commutator does not in the market carry out any processing to the welding position substantially, perhaps only plates the coating that one deck has only 0.01mm, so solid, the poor electric conductivity of not prison welding.
Summary of the invention
For overcoming the defective of prior art, the commutator that the technical problems to be solved in the utility model has provided a kind of firm welding, conducted electricity very well.
The technical solution of the utility model is: this commutator, its cylindrical outer wall covering copper layer, and the one end is provided with the hook that is connected with the enamelled wire of rotor winding is all warded off on the inwall of hook and the corresponding copper layer thereof and being connect the tin layer.
Because all ward off on the copper layer of the inwall of hook and correspondence thereof and connect the tin layer, so after parameters such as the pressure that mixes up spot welding machine, temperature, just can take off the insulating barrier of enamelled wire, and because the effect of temperature is fused to one with tin layer and enamelled wire, hook, their contacts area are increased, firm welding has reduced the internal resistance of junction simultaneously, has improved electric conductivity greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to the accompanying drawings, will be described in detail embodiment of the present utility model.
