Abstract
Abstract An electrical connector includes a housing having a plurality of cavities receiving a plurality of terminals therein, respectively, and an opening communicating with the terminal receiving cavities, and a retainer. The retainer includes a body engaged with the housing and movable in parallel with a longitudinal axis of the housing, and lock strips each coupled to the body and pivotable. Each lock strip is engaged with the housing through a guide which causes the lock strip to pivot inwardly and outwardly of the housing as the retainer is moved parallel to the longitudinal axis of the housing. Each lock strip has protrusions extending through the opening of the housing. The protrusions are moved inwardly and outwardly relative to the opening of the housing when each lock strip is pivot inwardly and outwardly of the housing. The lock strips engage the terminals received in the cavities, respectively, such that the terminals are held in position by the retainer.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
171 words
An electrical connector comprising: a plurality of terminals; a housing defining a plurality of cavities receiving said plurality of terminals therein, respectively, and an opening open to the terminal receiving cavities and an outer surface of the housing; and a retainer comprising a body engaged with the housing and movable parallel to a longitudinal axis thereof, and at least one lock strip coupled to the body and pivotable relative thereto, said lock strip and said housing including guide means for pivoting said lock strip inwardly toward and outwardly away from the housing as the retainer is moved parallel to the longitudinal axis of the housing in directions toward and away from the housing, respectively, said lock strip having protrusions extending into the opening of the housing, the protrusions moving inwardly and outwardly of the opening of the housing as the lock strip is pivoted toward and away from the housing, the protrusions engaging the terminals received in the cavities, respectively, such that the terminals are held in position by the retainer.
Claim 2
Dependent Claim
171 words
An electrical connector comprising: a plurality of terminals; a housing defining a plurality of cavities receiving said plurality of terminals therein, respectively, and an opening open to the terminal receiving cavities and an outer surface of the housing; and a retainer comprising a body engaged with the housing and movable parallel to a longitudinal axis thereof, and at least one lock strip coupled to the body and pivotable relative thereto, said lock strip and said housing including guide means for pivoting said lock strip inwardly toward and outwardly away from the housing as the retainer is moved parallel to the longitudinal axis of the housing in directions toward and away from the housing, respectively, said lock strip having protrusions extending into the opening of the housing, the protrusions moving inwardly and outwardly of the opening of the housing as the lock strip is pivoted toward and away from the housing, the protrusions engaging the terminals received in the cavities, respectively, such that the terminals are held in position by the retainer.
Claim 3
Dependent Claim
80 words
An electrical connector according to claim 1, wherein the guide means comprises a plurality of concave portions of the housing, and a plurality of guide protrusions formed on the retainer, each of said concave portions defining curved guide grooves into which the guide protrusions of said retainer extend, respectively, the lock strip being pivoted toward the housing via said guide protrusions as the retainer is moved parallel to the longitudinal axis of the housing in the direction toward the housing.
Claim 4
Dependent Claim
31 words
An electrical connector according to claim 2, wherein the retainer has at least one pair of holding strips, the holding strips holding the housing therebetween at outer sides of the housing.
Claim 5
Dependent Claim
64 words
An electric connector according to claim 2, wherein the housing has a guide recess extending parallel to the longitudinal axis of the housing, the guide grooves being formed to the sides of said guide recess, and the retainer has a guide convex portion extending into the guide recess of the housing, the guide protrusions being formed on opposite sides of the guide convex portion.
Claim 6
Dependent Claim
20 words
An electrical connector according to claim 3, wherein the retainer includes a tubular portion into which the housing is inserted.
Claim 7
Dependent Claim
20 words
An electrical connector according to claim 4, wherein the retainer includes a tubular portion into which the housing is inserted.
