Abstract

Abstract A rotary connector (1) which includes a fixed case(2, 5) and a rotatable case(4), each having an opening for connection with a lead wire, a flat cable(3) spirally wound and housed within the fixed and rotatable cases, the flat cable(3) having a plurality of electrical conductors(3a), and a connection terminal having one end connected to the electrical conductors of the flat cable and the other end connected to the lead wire and arranged at the opening of the rotatable case, wherein the flat cable is allowed to loosen and tighten to thereby permit the rotatable case to rotate relative to the fixed case. The rotary connector(1) further comprises a fixing member attached to the lead wire, and a retaining member(7) arranged at the opening of the rotatable case for engagement with the fixing member. The retaining member has a retaining portion for holding the lead wire in a predetermined position relative to the connection terminal.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 152 words
A rotary connector including a fixed case and a rotatable case, each having an opening for connection with a lead wire, a flat cable spirally wound and housed in the fixed and rotatable cases, the flat cable having a plurality of electrical conductors, and a connection terminal having one end connected to the electrical conductors of the flat cable and another end connected to a said lead wire and arranged at the opening of the rotatable case, the flat cable being allowed to loosen and tighten to thereby permit the rotatable case to rotate relatively to the fixed case, characterised in that there is provided a fixing member attached to the lead wire, and a retaining member arranged at the opening of the rotatable case for engagement with the fixing member, the retaining member having a retaining portion for holding the lead wire in a predetermined position relative to the connection terminal.
Claim 2
Dependent Claim 152 words
A rotary connector including a fixed case and a rotatable case, each having an opening for connection with a lead wire, a flat cable spirally wound and housed in the fixed and rotatable cases, the flat cable having a plurality of electrical conductors, and a connection terminal having one end connected to the electrical conductors of the flat cable and another end connected to a said lead wire and arranged at the opening of the rotatable case, the flat cable being allowed to loosen and tighten to thereby permit the rotatable case to rotate relatively to the fixed case, characterised in that there is provided a fixing member attached to the lead wire, and a retaining member arranged at the opening of the rotatable case for engagement with the fixing member, the retaining member having a retaining portion for holding the lead wire in a predetermined position relative to the connection terminal.
Claim 3
Dependent Claim 49 words
