Abstract
Abstract An electric connector including a housing made of resin and having a plurality of cavities for receiving a plurality of terminals and a terminal retaining member made of resin and having a plurality of holes. When a rear portion of the housing is inserted into an opening formed in a front portion of the terminal retaining member, the housing and terminal retaining member are preliminarily coupled with each other in a first coupling mode in which the holes of the terminal retaining member are aligned with the cavities of the housing. After the terminals having electric wires connected thereto have been inserted into the cavities through the holes, the terminal retaining member is shifted in a direction perpendicular to a direction in which the terminals are inserted and then is further moved toward the housing to attain a second coupling mode. In the second coupling mode the terminals are engaged with portions of the terminal retaining member to prevent the terminals from being removed out of the housing.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
222 words
An electric connector comprising a housing comprised of an electrically insulating material and having at least one cavity for receiving a terminal having an electric wire connected thereto and at least one retaining portion formed on an inner surface of the cavity; a terminal retaining member comprised of an electrically insulating material and having at least one hole through which said terminal can be passed; a first coupling means for coupling said housing and terminal retaining member with each other in a first coupling mode in which said at least one hole of the terminal retaining member is aligned with said at least one cavity of the housing thus permitting the terminal having the electric wire connected thereto to be inserted into the cavity through the hole, said retaining portion being engaged with a portion of the terminal in said first coupling mode and a second coupling means for coupling the housing and terminal retaining member with each other in a second coupling mode in which the entire terminal retaining member is shifted with respect to the housing at least in a direction perpendicular to a direction in which the terminal is inserted into the cavity, thus preventing the removal of said terminal from the cavity as a result of engagement between the terminal and a portion of the terminal retaining member.
Claim 2
Dependent Claim
222 words
An electric connector comprising a housing comprised of an electrically insulating material and having at least one cavity for receiving a terminal having an electric wire connected thereto and at least one retaining portion formed on an inner surface of the cavity; a terminal retaining member comprised of an electrically insulating material and having at least one hole through which said terminal can be passed; a first coupling means for coupling said housing and terminal retaining member with each other in a first coupling mode in which said at least one hole of the terminal retaining member is aligned with said at least one cavity of the housing thus permitting the terminal having the electric wire connected thereto to be inserted into the cavity through the hole, said retaining portion being engaged with a portion of the terminal in said first coupling mode and a second coupling means for coupling the housing and terminal retaining member with each other in a second coupling mode in which the entire terminal retaining member is shifted with respect to the housing at least in a direction perpendicular to a direction in which the terminal is inserted into the cavity, thus preventing the removal of said terminal from the cavity as a result of engagement between the terminal and a portion of the terminal retaining member.
Claim 3
Dependent Claim
61 words
An electric connector according to claim 1, wherein said first and second coupling means are so constructed that the terminal retaining member is moved in the direction perpendicular to the terminal inserting direction to release the first coupling mode and the terminal retaining member is moved further toward the housing in the terminal inserting direction to attain the second coupling mode.
Claim 4
Dependent Claim
47 words
An electric connector according to claim 1, wherein said first and second coupling means are so constructed that the terminal retaining member is moved in a direction inclined with respect to the terminal inserting direction to release the first coupling mode and attain the second coupling mode.
Claim 5
Dependent Claim
36 words
An electric connector according to claim 1, wherein said terminal retaining member comprises at least one projection formed therein, said projection being cooperatively engaged with a rear portion of the terminal in the second coupling mode.
Claim 6
Dependent Claim
30 words
An electric connector according to claim 4, wherein said projection of the terminal retaining member is cooperatively engaged with a rear end of the terminal in the second coupling mode.
Claim 7
Dependent Claim
63 words
An electric connector according to claim 1, wherein said terminal retaining member has an opening formed in a front portion thereof, the cross sectional shape of said opening substantially corresponding to an outer configuration of the rear portion of the housing, whereby the rear portion of the housing may be inserted into the opening in the front portion of the terminal retaining member.
Claim 8
Dependent Claim
58 words
An electric connector according to claim 6, wherein said first coupling means comprises at least one projection formed on an outer surface of the rear portion of the housing, and at least one hole formed in the front portion of the terminal retaining member, with said projection being cooperatively engaged with said hole in the first coupling mode.
Claim 9
Dependent Claim
57 words
An electric connector according to claim 6, wherein said first coupling means comprises at least one hole formed in the rear portion of the housing, and at least one projection formed on an outer surface of the front portion of the terminal retaining member, whereby said projection is engaged with said hole in the first coupling mode.
Claim 10
Dependent Claim
54 words
An electric connector according to claim 6, wherein said second coupling means comprises at least one projection formed in the rear portion of the housing, and at least one hole formed in the front portion of the terminal retaining member, whereby said projection is cooperatively engaged with said hole in the second coupling mode.
Claim 11
Dependent Claim
58 words
An electric connector according to claim 6, wherein said second coupling means comprises at least one projection formed on an outer surface of the rear portion of the housing, and at least one hole formed in the front portion of the terminal retaining member, whereby said projection is cooperatively engaged with said hole in the second coupling mode.
Claim 12
Dependent Claim
65 words
An electric connector according to any one of claims 7 to 10, wherein said first coupling means comprises at least one guide groove formed in the outer surface of the rear portion of the housing and at least one locking arm formed on the outer surface of the front portion of the terminal retaining member, said locking arm being inserted and moved in said groove.
Claim 13
Dependent Claim
76 words
An electric connector according to claim 11, wherein said second coupling means comprises at least one guide groove formed in the outer surface of the rear portion of the housing and communicating with said guide groove of the first coupling means by means of an intermediate guide groove formed in the outer surface of the rear portion of the housing and inclined with respect to the direction in which the terminal is inserted into the cavity.
Claim 14
Dependent Claim
50 words
An electric connector according to claim 12, wherein said second coupling means further comprises a pawl formed at a free end of the locking arm and a locking edge formed in the outer surface of the housing, said pawl being engaged with said locking edge in the second coupling mode.
