Problems solved by technology

However, if the number of connected circuits is small and only one flat cable is installed, and the number of connected circuits is large and two flat circuits are installed, the number and arrangement of lead block pin terminals are very different. The size of the insulating base of the lead block will also change accordingly, so it is necessary to change and separately manufacture the designated parts of the stator housing and the rotor housing where the insulating base is installed (connector setting part) according to the number of flat cables. )Structure
Therefore, there is a problem that the cost of parts for the stator case and the rotor case increases, making it difficult to reduce the cost of the product

Abstract

The present invention provides a rotary connector which can reduce the cost of stator casing or rotor casing even the sheet numbers of flat cables are different thereby realizing the low cost of product. The rotary connector is installed with one piece of flat cable in the receiving space formed between the stator casing and the rotor casing. Needle shaped terminal group fixed on the insulating substrate of lead block is connected with the end of flat cable. An insulating substrate is installed on the casing. The needle shaped terminal casing is integratedly configured on one side area which is obtained through approximately bisecting the exposed end plane of insulated substrate, and the other side area is not configured with the needle shaped terminal. One piece of flat cable is additionally installed at the state the number of connected circuit is many. The other needle shaped terminal group which is connected with the flat cable can be integratedly configured on the other side areaof exposed end plane. The lead block can be formed through the insulated subtrates with same size and shape. The stator casing or rotor casing can be used commonly.

Description

technical field [0001] The present invention relates to a rotary connector mounted on a steering device of an automobile and used as an electrical connection mechanism for an air bag system or the like. Background technique [0002] The rotary connector includes a stator housing, a rotor housing, and a flat cable (flat cable). The stator housing is fixed to a combination switch assembly or the like of the steering gear; the rotor housing is mounted on the steering wheel side; the flat cable The cables are housed in a coiled state in an annular housing space formed between the stator case and the rotor case. Furthermore, this rotary connector is used as an electrical connection mechanism for an airbag gas generating device and the like attached to a steering wheel with a limited rotational speed. Moreover, conventionally known rotary connectors of this type are provided with a lead block for holding a plurality of pin terminals (Pin Terminals) on an insulating base. The pin...
