Description

one

The invention relates to slide-in devices for transmitting electrical signals between parts in mutual interconnection.

Known collector device containing as a contact element flexible conductor, pressed to the contact ring by a spring. An electrical signal is applied to the flexible conductor through the input wire, and is removed from the rotating ring using a wire connected to it. The drawback of the device is that the device has significant self-noise and overheating above the permissible, occurring at high speeds of rotation.

A collector device is known, which contains as a contact element a spring sliding along a smooth contact ring. The electrical signals in it are fed to a fixed spring, which, due to its extension, creates the necessary pressure of the turn-contacts on the rotating contact ring. Electrical signals are removed from the rotating slip ring. However, this device also leads to a high level of noise and distortion of the transmitted electrical signals.

The invention allows to reduce the distortion of electrical signals and reduce the level of noise in the transmission of electrical signals.

through the current collector contacts, preferably at high speeds of rotation. This is achieved by the fact that the screw npyavnHa is located in a radial clearance smaller than the diameter of the spring coil. Due to this, the plane of each turn is spring-type relative to the radial direction of the contact ring at an angle greater than zero, but less than 90 °. The parts of the coils in contact with the slip ring are made in contact with each other.

FIG. 1 shows a current collection device; in fig. 2 - a section on a contact spring.

The current collector consists of an inner contact ring 1, a coil spring 2 and an outer race 3 with an undercut.

The contact elements are insulated and packaged: the inner contact rings on the roller 4, the outer cages 3 in the housing 5. The device operates as follows.

Electric sigals are fed through the input conductors to the contact 2 and through its coil contacts to the inner contact ring 1. The electrical sigals are removed from the conductors connected to the inner ring 1.

The presence of turns of the contact spring inclined relative to the radial direction, as well as their mating with the contact point of the contact ring, allows to significantly reduce the level of noise induced by the collector device. For example, when a collector is operated at a speed of 5500 rpm and a signal voltage of 12 MB, a current of 10 mA, the noise level is removed more than 50 times.
