Abstract
Abstract A connector device for a steering system of an automobile is provided, in which a movable member is securely locked to its predetermined initial position when the device is mounted or remounted to a steering system so that it can effectively eliminate any errors in the mounting or remounting operation and the locked condition of the movable member is automatically released when the device is properly set in position. Moreover, since the locking mechanism is accommodated in the inner room (compartment) of the device where axially a relatively large space is available, the device has a variety of advantages including a relatively reduced thickness.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
199 words
A connector device for a steering system comprising an inner compartment and an outer compartment formed between a movable member and a fixed member which are rotatably connected to each other, said inner compartment accommodating a conductor plate and a scraper electrically engaged with said conductor plate, whereas said outer compartment accommodates a cable wound in a plurality of turns, said conductor plate and said scraper being moved relative to each other as the movable member is rotated and at the same time said cable is being wound or unwound according to the direction of rotation of said movable member, wherein said device further comprises a partition wall provided on said fixed member projecting into said inner compartment for rigidly fixing either said conductor plate or said scraper to an upper surface of said partition wall, an anchoring member located along the inner periphery of said partition wall, a stopper member provided on said movable member and resiliently biased against said anchoring member to prevent movement between said fixed and movable members, and an unlocking member being provided on said stopper member for releasing said stopper member from said anchoring member as external equipment presses against said unlocking member.
Claim 2
Dependent Claim

A connector device for a steering system comprising an inner compartment and an outer compartment formed between a movable member and a fixed member which are rotatably connected to each other, said inner compartment accommodating a conductor plate and a scraper electrically engaged with said conductor plate, whereas said outer compartment accommodates a cable wound in a plurality of turns, said conductor plate and said scraper being moved relative to each other as the movable member is rotated and at the same time said cable is being wound or unwound according to the direction of rotation of said movable member, wherein said device further comprises a partition wall provided on said fixed member projecting into said inner compartment for rigidly fixing either said conductor plate or said scraper to an upper surface of said partition wall, an anchoring member located along the inner periphery of said partition wall, a stopper member provided on said movable member and resiliently biased against said anchoring member to prevent movement between said fixed and movable members, and an unlocking member being provided on said stopper member for releasing said stopper member from said anchoring member as external equipment presses against said unlocking member.
Claim 3
Dependent Claim
94 words
A connector device for a steering system according to claim 1, wherein said unlocking member comprises a portion of said stopper member provided on the inner periphery of said movable member, said stopper member being so designed that it becomes engaged with said anchoring member provided on said lower surface of said projecting wall of said fixed member under the resilient force of a spring member accommodated under said unlocking member, and said stopper member becoming released from the engagement with said anchoring member of said fixed member as said spring member is compressed.
Claim 4
Dependent Claim
26 words
A connector device for a steering system according to claim 1, wherein said external equipment that compresses said spring member from outside is a steering hub.
Claim 5
Dependent Claim
26 words
A connector device for a steering system according to claim 1, wherein a supporting member is provided under said stopper member for supporting the spring member.
