Abstract
Abstract A partially pre-assembled electrical connector has metal terminals partially inserted in a housing. The connectors are completed by at least partially withdrawing each terminal from the housing, placing the end of a wire in the exposed portion of the terminal, crimping the terminal on the wire, and then fully inserting the terminal in the housing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
189 words
A partially pre-assembled electrical connector comprising: a housing having a plurality of longitudinal, laterally adjacent, substantially parallel apertures, each aperture extending all the way through the housing between front and rear surfaces of the housing; a plurality of flexible latches disposed on one side of said housing in corresponding one-to-one relationship with said apertures, each latch having a nose portion which extends into its associated aperture; a longitudinal metal terminal partially inserted into each aperture at the rear surface of said housing in a direction substantially parallel to the longitudinal axis of the associated aperture, each terminal having a front disconnect portion with a downwardly bowed spring member and an uncrimped rear wire portion, the disconnect portion being disposed in the aperture and at least a portion of the wire crimp portion being outside the housing to the rear of the rear surface, the nose portion of each latch being in biased contact with the bowed spring member of the disconnect portion of the associated terminal to a degree sufficient to retain said terminal position against inadvertent withdrawal but not sufficient to permanently latch said terminal in the housing.
Claim 2
Dependent Claim
189 words
A partially pre-assembled electrical connector comprising: a housing having a plurality of longitudinal, laterally adjacent, substantially parallel apertures, each aperture extending all the way through the housing between front and rear surfaces of the housing; a plurality of flexible latches disposed on one side of said housing in corresponding one-to-one relationship with said apertures, each latch having a nose portion which extends into its associated aperture; a longitudinal metal terminal partially inserted into each aperture at the rear surface of said housing in a direction substantially parallel to the longitudinal axis of the associated aperture, each terminal having a front disconnect portion with a downwardly bowed spring member and an uncrimped rear wire portion, the disconnect portion being disposed in the aperture and at least a portion of the wire crimp portion being outside the housing to the rear of the rear surface, the nose portion of each latch being in biased contact with the bowed spring member of the disconnect portion of the associated terminal to a degree sufficient to retain said terminal position against inadvertent withdrawal but not sufficient to permanently latch said terminal in the housing.
Claim 3
Dependent Claim
48 words
A connector according to claim 1 wherein the front disconnect portion has a transverse cross section which in generally in the shape of a hollow rectangle, the upper side of said rectangle comprising said spring which bends downwardly, said nose portion of each latch contacting said bowed spring.
Claim 4
Dependent Claim
31 words
A connector according to claim 1 wherein the portion of the uncrimped wire crimp portion which is outside the housing is too large to fit in the associated aperture while uncrimped.
Claim 5
Dependent Claim
17 words
A connector according to claim 3 wherein said portion outside the housing includes an insulation crimp portion.
Claim 6
Dependent Claim
49 words
A connector according to claim 1 wherein after a wire is crimped to the wire crimp portion, further insertion of said terminals will cause the nose portion of each latch to drop into a notch at the rear of the disconnect portion to latch the terminals in the housing.
