Abstract

Abstract An electric connector with a terminal conductor detaining mechanism for restraining terminal conductors from slipping out of the electric connector. The electric connector comprises: a connector shell having a plurality of terminal chambers and provided with a pair of flexible, temporary locking strips and with a pair of main locking parts; and a terminal conductor detaining member provided with a plurality of terminal conductor detaining fingers and a pair of flexible locking arms. The terminal conductor detaining member is combined temporarily with the connector shell with the fexible locking arms thereof engaging the flexible locking strips of the connector shell, respectively, to keep the connector shell and the terminal conductor detaining member in a temporarily combined state. The terminal conductor detaining member is combined completely with the connector shell by pressing the terminal conductor detaining member into the connector shell so that the locking arms engage the main locking parts of the connector shell, respectively. In pressing the terminal conductor detaining member into the connector shell to combine the terminal conductor detaining member and the connector shell in a completely combined state, the flexible locking strips must be pressed forcibly to allow the terminal conductor detaining member to move further into the connector shell. Thus, the accidental complete combination of the terminal conductor detaining member and the connector shell is prevented.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 157 words
An electric connector with a terminal conductor detaining mechanism, comprising: a connector shell having a plurality of elongate terminal chambers and provided with provisional locking means and final locking means inwardly forwardly of said provisional locking means in said connector shell; a terminal conductor detaining member provided with a plurality of terminal conductor detaining fingers to be received respectively in the terminal chambers of the connector shell when the terminal conductor detaining member is combined with the connector shell, said terminal conductor detaining member having at least one flexible locking arm to be temporarily arrested by said provisional locking means, said provisional locking means being flexible and capable, when pressed, of deforming said at least one flexible locking arm inwardly to override and snap outwardly past said final locking means while the terminal conductor detaining member is pressed forwardly into the connector shell such that said connector shell and said terminal conductor detaining member are finally locked.
Claim 2
Dependent Claim 157 words
An electric connector with a terminal conductor detaining mechanism, comprising: a connector shell having a plurality of elongate terminal chambers and provided with provisional locking means and final locking means inwardly forwardly of said provisional locking means in said connector shell; a terminal conductor detaining member provided with a plurality of terminal conductor detaining fingers to be received respectively in the terminal chambers of the connector shell when the terminal conductor detaining member is combined with the connector shell, said terminal conductor detaining member having at least one flexible locking arm to be temporarily arrested by said provisional locking means, said provisional locking means being flexible and capable, when pressed, of deforming said at least one flexible locking arm inwardly to override and snap outwardly past said final locking means while the terminal conductor detaining member is pressed forwardly into the connector shell such that said connector shell and said terminal conductor detaining member are finally locked.
Claim 3
Dependent Claim 62 words
An electric connector according to claim 1, wherein said provisional locking means includes a pair of flexible locking strips each formed by a channel-shaped slit in said connector shell to have a forward free end, each flexible locking strip having a temporary locking projection, said temporary locking projection having a guide slope formed on an inner rearward surface of the flexible strip.
Claim 4
Dependent Claim 25 words
An electric connector according to claim 2, wherein said final locking means includes a main locking projection formed forwardly of said each flexible locking strip.
Claim 5
Dependent Claim 43 words
An electric connector according to claim 1, wherein said connector shell has guide groove means formed on an inner wall thereof to receive said at least one flexible locking arm therein, said guide groove means extending substantially parallel to said elongate terminal chambers.
Claim 6
Dependent Claim 111 words
An electric connector according to claim 1, wherein said connector shell has guide groove means formed in an inner wall thereof to receive said at least one flexible locking arm therein, said guide groove means extending at an angle to said elongate terminal chambers such that said conductor detaining fingers of said terminal conductor detaining member are kept clear of passages of terminal conductors when said terminal conductor detaining member and said connector shell are temporarily locked whereas said conductor detaining fingers of said terminal conductor detaining member engage corresponding terminal conductors to detain the corresponding terminal conductors when said terminal conductor detaining member and said connector shell are finally locked.
