1) contact on the rotating part distributes along axis on circumference, when the contact quantity that requires more for a long time, the axial dimension of connector is increased greatly.
2) adopt columnar rotating parts, operating difficulties to the contact welding lead on its circumference the time.
3) rotating parts adopts plastic material, and heat resistance is not so good, can not be used for high-temperature work environment.
(3) summary of the invention
The utility model provides a kind of convenience conductive plate efficiently in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of conductive plate, comprise spinning disk, lug plate, becket and current collector matching used with it, it is characterized in that: be distributed with several concentric convexes on the face of described spinning disk, a boring is arranged below each convex on another face, the degree of depth in hole reaches and makes that groove communicates between hole and convex, these holes distribute with the helix form of shrinking to the spinning disk center along the circumference of spinning disk.
The more excellent technical scheme of the utility model is: the boring of spinning disk and convex surface are provided with the metal coat layer that electrically contacts between the metal that has been used for guaranteeing each convex and its corresponding hole.
In the hole of spinning disk lug plate is arranged, the lead of rotating part circuit is received on the lug plate.Clad spinning disk convex is welded with flat becket on the plane, and the gross thickness of metal is identical between its thickness and convex.
The beneficial effects of the utility model are: have good electric conductivity and insulation property, and good thermal endurance, simple in structure, rotation steadily, advantages such as bonding wire is convenient when being connected with external circuit, and the line number that can arrange is many, and in light weight, cost is low, safe and reliable, mechanical endurance is long.Be applicable to the connection between the circuit that has relative rotary motion in instrument, the instrument, can meet the demands especially has the occasion of very little axial dimension.
