Abstract

A conductive sliding ring rotor comprises a rotary mainshaft, an insulating ring and a conductive sheet; an insulating ring is sheathed on the mainshaft; the insulating ring comprises a first ring and a second ring; the external diameter of the first ring is more than that of the second ring; the second ring is provided with an opening; the bottom of the opening is provided with a wire hole; and the conductive sheet is arranged in the opening of the second ring. When the rotor rotates, if an electric brush wire of a stator part is contacted with the conductive sheet that is arranged in the second ring, a loop is formed; if the electric brush wire of the stator part is contacted with the second ring of the insulating ring, the circuit is broken; and the electric brush wire and the conductive sheet are intermittently connected with each other, thus realizing the intermittent transmission of the current of two relative rotation mechanisms.

Description

The conducting slip ring rotor

Technical field

The utility model belongs to electric equipment, relates in particular to a kind of conducting slip ring.

Background technology

As everyone knows, conducting slip ring claims collector ring, rotary joint, rotation electric interfaces, industrial slip ring, collecting ring, backflow ring, coil, commutator or adapter or the like again, is to realize two to relatively rotate the signal of mechanism and the accurate power transmitting device of current delivery.

The rotor of existing laminated conductive retractor collar is made up of conducting ring, dead ring and rotating shaft, dead ring and conducting ring stack are enclosed within on the rotary main shaft, the conducting slip ring of this structure can only be realized two transmission that relatively rotate the current continuity of mechanism, can't finish the discontinuity transmission of current signal.

The utility model content

Technical problem to be solved in the utility model provides a kind of conducting slip ring rotor, and this conducting slip ring can be realized two discontinuity transmission that relatively rotate the electric current of mechanism.

In order to address the above problem, the utility model is taked following technical scheme: a kind of conducting slip ring rotor, comprise: rotary main shaft, dead ring, conducting strip, it is characterized in that, described dead ring comprises first annulus and second annulus, the described first annulus external diameter is greater than the second annulus external diameter, and described second annulus is provided with gap, and described conducting strip is installed in the gap of described second annulus.

Preferred version, at least two gap of the described second annulus setting.

Preferred version, the thickness of described conducting strip is identical with the thickness of described gap.

The conducting slip ring rotor that the utility model provides, the structure that changes original monocycle dead ring is a twin nuclei, on the less dead ring of external diameter a plurality of gap are set therein, conducting strip is installed in gap, when rotor rotation, if the brush wire of stationary part contacts with the conducting strip that is arranged on second annulus, then form path; If the brush wire of stationary part contacts with second annulus of dead ring, then form and open circuit, brush wire and conducting strip off and on, thereby realize two discontinuity transmission that relatively rotate the electric current of mechanism.

Description of drawings

Fig. 2 is the dead ring generalized section of the utility model conducting slip ring rotor;

Fig. 3 is the dead ring overall package figure of the utility model conducting slip ring rotor.

Embodiment

For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As depicted in figs. 1 and 2, the dead ring 11 of the utility model conducting slip ring rotor is two-layer, comprise: first annulus 12 and second annulus 13, the external diameter of described second annulus 13 are less than the external diameter of first annulus 12, and wherein first annulus 11 is connected as a whole with second annulus by injection mold; Second annulus 13 of described dead ring 11 is provided with gap 14, and conducting strip 15 is installed in its gap 14, and outside electric wire is connected with conducting strip by the plug wire hole that is arranged on the setting of described gap 14 bottoms.

As shown in Figure 3, the described first annulus external diameter is arranged to greater than the second annulus external diameter, after dead ring fits together, dead ring closely superposes, second annulus of dead ring forms a groove 31 between two dead rings of being close to, brush wire is placed in the groove 31 and contacts with second annulus of dead ring, guarantees that the brush wire aligning is arranged on the conducting strip in the insulating trip gap.

The dead ring stack that has conducting strip is installed on the rotary main shaft of conducting slip ring, the brush of slip ring stationary part contacts with second annulus of slip-ring rotor dead ring, when conducting slip ring rotates,, then form path if the brush wire of stationary part contacts with the conducting strip that is arranged on second annulus; If the brush wire of stationary part contacts with second annulus of dead ring, then form and open circuit, brush wire contacts with conducting strip discontinuity, thereby realizes two discontinuity transmission that relatively rotate the electric current of mechanism.
