Laminated conductive rotary slip ring and producing process

Abstract

The invention relates to a revolving and slip ring type circuit connector. It consists of spindle, insulating piece, conducting ring, bearing shell. The insulation piece and conducting ring with wire each sleeves on the triangle major axis. Then the bearing shell is sleeved and the dung is injected. The conducting revolving axis is easily made. The invention divides the conducting revolving axis into several individual component parts and changes the injection mould technology into lamination adhesive bonding technology.

Description

technical field [0001] The invention relates to a rotary slip ring type circuit connection joint, which is a new rotating shaft of a conductive ring. It is a precision device for transferring images and data signals between two relative rotating mechanisms, and is used in places where electric energy is transmitted from a fixed position to a continuously rotating position. Background technique [0002] Conductive slip rings are also called collector rings or rotary joints. Domestically, we mainly rely on the "Lite" 6023 model produced in the United States. Its key component, the rotating shaft of the conductive ring, is injection molded by plastic at one time, and then manually cut by a lathe to finally obtain a qualified product. The main technical problems of the "Lite" 6023 model product are reflected in the following three points: [0003] 1. The single-piece conductive ring has small size, thin wall, outer diameter ∮7.8mm, thickness 0.8mm, and inner hole ∮6mm. During...

This process has many steps and is labor-intensive

[0005] 3. When manufacturing "Lite" 6023, each type of rotating shaft of the conductive ring needs a pair of molds and 3 to 5 pairs of cavity movable inserts, and the manufacturing cost is relatively high
