Abstract

PURPOSE: To miniaturize a multi-core slip ring and to easily manufacture it by overlapping a fixed side substrate, a rotary side substrate, and a contact plate with spring property coaxially for constituting the multi-core slip ring. CONSTITUTION: A fixed side substrate 4 and a rotary side substrate 5 with a conductive part on each opposing surface are overlapped mutually and coaxially for arrangement and at the same time a contact plate 6 with a spring property for a continuity between both substrate is 4 and 5 is held between both substrates 4 and 5. In this manner, by successively overlapping the fixed side substrate 4 and the rotary side substrate 5 with an included contact plate 6, a lip ring with a desired number of cores can be obtained, thus constituting a multi-core slip ring with a small diameter and short length and hence miniaturizing the multi-core slip ring and easily manufacturing it.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-core slip ring device for a rotating device used in a low speed rotating part.

[0002]

2. Description of the Related Art As a conventional technique, one using a conductive portion 8a of a rotating cylinder 8 and a contactor 9 as shown in FIG. 3 and one using a conductive portion of a disk 10 and a contactor 11 as shown in FIG. It was a slip ring.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The use of multiple cores has a drawback that the length using a cylinder becomes long and the diameter using a disk increases.

An object of the present invention is to provide a multi-core slip ring which is small in size and easy to manufacture except for these drawbacks.

[0005]

In order to achieve the above object, the present invention comprises a fixed-side substrate, a rotating-side substrate, and a contact plate having a spring property, which are coaxially overlapped with each other to form a multi-core slip ring. It was done.

[0006]

The fixed board has coaxially independent conductive surfaces on both sides, and the rotary board also has a conductive surface. Both boards are sequentially stacked with a contact plate having a spring property interposed therebetween. The slip ring with the desired number of cores can be made by going.
Therefore, a multi-core slip ring having a small diameter and a short length is constructed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a structural diagram of a slip ring device.
Is a fixed shaft, and the fixed side substrate 4 is integrated into one body by the fixed pin A. Similarly, 2 is a rotating shaft, and 1 is a fixing pin B for the rotating side substrate 5.
It has become a physical body. A contact plate 6 having a spring property is sandwiched between the two substrates 4 and 5, so that even if the rotating shaft 2 rotates, conduction is obtained between the conductive surfaces of the two substrates, and the wire 7 is not twisted due to the rotation and the current and Signal can be transmitted.

FIG. 2 shows in detail the relationship between the fixed-side substrate 4, the rotating-side substrate 5, and the contact plate 6 having a spring property, and the transmission of current or signals between the fixed shaft side and the rotating shaft side. It is performed through a contact plate 6 having a conductive property and a spring property, which is narrowed between the fixed-side substrate 4 and the rotating-side substrate 5. The contact plate may be fixed to either one of the fixed-side substrate 4 and the rotating-side substrate, or may not be fixed to any of them.

[0010]

As described above, according to the present invention, two circuits can be obtained from one board, and the distance between the boards can be narrowed, so that the size can be reduced even if the number of cores is increased. Further, the number of cores can be arbitrarily increased or decreased, and the substrate can be manufactured at low cost by using a printing technique and the assembling can be facilitated.
