Problems solved by technology
[0002] At present, DC speed-regulating motors are widely used in the market, but the electrical connection between the circuit modules of a large number of DC speed-regulating motors and the three-phase (or multiple) armature windings is connected by wire welding. This connection method has welding requirements. Disadvantages such as high height, many wires, complicated connection and routing, low reliability, large space occupation, difficult maintenance, and poor modular design

The invention provides a direct current adjustable-speed motor vibrating needle type contact connecting device. Armature winding copper wire terminals (8) are directly welded to vibrating needle contact discs (6) on an insulation sheet (7), so that motor stators (2) are formed; the insulation sheet (7) is fixed to the motor stators (2), at least three gold-plated vibrating needle contact discs (6) are embedded in the insulation sheet (7) according to the outgoing line positions of the armature winding copper wire terminals (8), outgoing lines of the armature winding copper wire terminals (8) and the vibrating needle contact discs (6) are welded into a whole, and therefore the insulation sheet (7) and the vibrating needle contact discs (6) are firmly fixed to the motor stators (2). According to the direct current adjustable-speed motor vibrating needle type contact connecting device, electromechanical modularized design of a motor is achieved, all parts are produced through dies, the standardization degree of the parts of the motor is greatly increased, installation and detachment are convenient, the internal space of the motor is reduced, the whole size of the motor is small, great convenience is provided for selection of a user, and the reliability and large-scale production efficiency of the motor are improved.
Description
technical field [0001] The invention belongs to the technical field of the application of a spring pin contact connection structure to the electric connection structure between a circuit module and an armature winding of a DC speed regulating motor circuit module with small volume, adjustable rotation speed, high rotation speed and high temperature resistance. Background technique [0002] At present, DC speed-regulating motors are widely used in the market, but the electrical connection between the circuit modules of a large number of DC speed-regulating motors and the three-phase (or multiple) armature windings is connected by wire welding. This connection method has welding requirements. Higher, more wires, complex connection and wiring, low reliability, larger space occupation, difficult maintenance, poor modular design and other shortcomings. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention proposes a spring-...
