Abstract
Abstract The connector assembly includes a housing having a latch, a terminal to be inserted in the housing and fixed thereto by the latch, and a retainer insertable into the housing to a regular latching position at which the retainer locks the latch in position to maintain the fixing of the terminal to the housing with the latch. The retainer has a catch which will be contacted by the terminal if the retainer is in the regular latching position prior to insertion of the terminal into the housing. In this case, insertion of the terminal into the housing pushes the retainer from the regular latching position to free the latch and allow the terminal to be engaged and held by the latch.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
294 words
An electrical connector assembly comprising: a housing having a forward end and a rear end, said housing defining a terminal insertion cavity open at the rear end thereof and a retainer receiving cavity open at the forward end thereof, and said housing having a movable latch associated with said terminal insertion cavity, a terminal insertable into said terminal insertion cavity of the housing from said rear end of the housing, said terminal having a latch receiving portion which engages said latch of the housing when the termainal is in a fully inserted position in said terminal insertion cavity, and the engagement between said latch of the housing and the latch receiving portion of said terminal preventing said terminal from being pulled out of said housing from said rear end thereof; and a retainer insertable into said retainer receiving cavity of the housing from said front end of the housing, said retainer having a locking portion engageable with said movable latch when said retainer is in a regular latching position in said retainer receiving cavity, and the engagement of said locking portion with said movable latch fixing said latch in position to maintain the engagement between said latch and the latch engaging portion of said terminal when the terminal is in the fully inserted position thereof, characterized in that: said terminal has a retainer contacting portion; and said retainer has a catch which will be contacted by the retainer contacting portion of said terminal when said retainer is in said regular latching position thereof as said terminal is being inserted into said terminal insertion cavity such that said retainer will be moved by said terminal from said regular latching position thereof thereby freeing said latch for engagement with the latch receiving portion of said terminal.
Claim 2
Dependent Claim
139 words
An electrical connector assembly according to claim 1, wherein said housing has a retainer engaging portion associated with said retainer receiving cavity, and said retainer has housing engaging portions sequentially engageable with said retainer engaging portion of the housing as the retainer is inserted into said retainer receiving cavity to hold said retainer in a temporary latching position and in said regular latching position, respectively, the locking portion of said retainer being out of engagement with said latch when the retainer is in said temporary latching position, and said terminal moving said retainer from said regular latching position to said temporary latching position by contact between said retainer contacting portion of said terminal and the catch of said retainer when said terminal is inserted into said terminal insertion cavity while said retainer is located in said regular latching position.
Claim 3
Dependent Claim
62 words
An electrical connector assembly according to claim 2, wherein said movable latch comprises an extendable and retractable arm, said arm being in an extended position when engaging the latch receiving portion of said terminal disposed in the fully inserted position thereof, and said locking portion of the retainer preventing said arm from retracting when said retainer is in said regular latching position.
Claim 4
Dependent Claim
69 words
An electrical connector assembly according to claim 3, wherein said housing defines an evacuation space contiguous to said retainer receiving cavity, and said catch of the retainer comprises a flexible protrusion, said flexible protrusion being bent into said evacuation space by said retainer contacting portion of the terminal when said retainer is inserted to said regular latching position thereof while said terminal is in said fully inserted position thereof.
Claim 5
Dependent Claim
20 words
An electrical connector assembly according to claim 4, wherein said flexible protrusion has the shape of a thin flat plate.
Claim 6
Dependent Claim
47 words
An electrical connector assembly according to claim 5, wherein said arm has a flat surface, and the retainer contacting portion of said terminal comprises a flat plateshaped member which slidably engages the flat surface of said arm as said terminal is inserted into said terminal insertion cavity.
