Abstract

Abstract A wire harness connection structure includes a connector housing having a plurality of terminal cavities, each of which is equipped with a groove 4 for guiding a reverse inversion preventing projection 6 provided on the terminal when the terminal is inserted in the normal fashion and a tapered guide surface 5 for guiding the projection 6 when the terminal is reversely inserted. When the terminal is reversely inserted, the projection 6 is prevented from moving forwards, thus making the insertion of the terminal impossible.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 227 words
A wire harness connection structure comprising: a connector housing having a plurality of terminal cavities, each of which provides a space defined by side walls; a metallic wire terminal which is to be inserted into one of said terminal cavities and which is equipped with a stopper for preventing said terminal from moving if said terminal is reversely inserted into one of said terminal cavities; locking means provided in each of said terminal cavities and which is adapted to engage and support said terminal when said terminal is inserted into one of said terminal cavities; normal insertion guide means provided in each of said terminal cavities and which is adapted to guide said stopper when said terminal is inserted into one of said terminal cavities in a normal fashion; and reverse insertion guide means provided in each of said terminal cavities and which is adapted to guide said stopper in a direction perpendicular to the longitudinal axis of said terminal cavities if said terminal is reversely inserted into one of said terminal cavities; wherein said locking means is provided with an engagement section, which lodges said stopper when said terminal is inserted deep into one of said terminal cavities, and a stop section which, if said terminal is reversely inserted into one of said terminal cavities, abuts against said stopper guided by said reverse insertion guide means.
Claim 2
Dependent Claim 227 words
A wire harness connection structure comprising: a connector housing having a plurality of terminal cavities, each of which provides a space defined by side walls; a metallic wire terminal which is to be inserted into one of said terminal cavities and which is equipped with a stopper for preventing said terminal from moving if said terminal is reversely inserted into one of said terminal cavities; locking means provided in each of said terminal cavities and which is adapted to engage and support said terminal when said terminal is inserted into one of said terminal cavities; normal insertion guide means provided in each of said terminal cavities and which is adapted to guide said stopper when said terminal is inserted into one of said terminal cavities in a normal fashion; and reverse insertion guide means provided in each of said terminal cavities and which is adapted to guide said stopper in a direction perpendicular to the longitudinal axis of said terminal cavities if said terminal is reversely inserted into one of said terminal cavities; wherein said locking means is provided with an engagement section, which lodges said stopper when said terminal is inserted deep into one of said terminal cavities, and a stop section which, if said terminal is reversely inserted into one of said terminal cavities, abuts against said stopper guided by said reverse insertion guide means.
Claim 3
Dependent Claim 19 words
A connection structure as claimed in claim 1, wherein said stopper comprises a tab radially protruding from said terminal.
Claim 4
Dependent Claim 26 words
A connection structure as claimed in claim 1, wherein said reverse insertion guide means comprises a tapered surface raised from a wall of said connector housing.
Claim 5
Dependent Claim 25 words
A connection structure as claimed in claim 1, wherein said normal insertion guide means is formed on the side wall opposed to said locking means.
Claim 6
Dependent Claim 26 words
A connection structure as claimed in claim 4, wherein said normal insertion guide means extends in the direction of a longitudinal axis of said locking means.
Claim 7
Dependent Claim 27 words
A connection structure as claimed in claim 1, wherein said locking means consists of a flexible member which protrudes from one of said side walls defining said
Claim 8
Dependent Claim 24 words
A connection structure as claimed in claim 6, wherein said reverse insertion guide means is formed between said flexible member and said side wall.
Claim 9
Dependent Claim 19 words
A connection structure as claimed in claim 6, wherein said stopper comprises a tab radially protruding from said terminal.
