Abstract
Abstract A connector comprises a housing for receiving terminals therein, a secondary locking member mountable thereto and a linear bayonet type of slide-lock member to assist coupling of the connector to a complementary connector. In the preassembly position, the slide lock member is in a fully closed position where shoulders engage with latches of the secondary locking member which is in the preassembly position allowing reception of terminals in cavity of the connector housing. When the secondary locking member is depressed into its fully locked position, the latches disengage from the shoulders of the slide-lock member, thus allowing it to be opened to enable coupling to the complementary connector. Due to the slide-lock member being in a fully closed position when the secondary locking member is in a preassembly position, coupling between the connector with a complementary connector is prevented, and in particular not even partial coupling is allowed as the complementary connector studs cannot engage in the camming slots at all.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
163 words
An electrical connector comprising a housing with cavities extending therethrough for receiving electrical terminals therein, a secondary locking member mountable to the housing in a first preassembly position where the terminals can be inserted into their corresponding cavities and movable to a fully locked position to securely lock the terminals in their corresponding cavities, the connector further comprising a slide-lock coupling mechanism to assist coupling of the connector to a complementary connector by movement of the slide-lock member from an open position where the complementary connector is received to a closed position where the connectors are coupled, characterized in that the slide-lock coupling member and secondary locking member have interengageable shoulder and latch members that engage each other when the secondary locking member is in the preassembly position to prevent movement of the slide-lock member (10) for coupling, the latch members being disengaged when the secondary locking member is in the fully locked position to allow movement of the slide-lock member for coupling.
Claim 2
Dependent Claim
163 words
An electrical connector comprising a housing with cavities extending therethrough for receiving electrical terminals therein, a secondary locking member mountable to the housing in a first preassembly position where the terminals can be inserted into their corresponding cavities and movable to a fully locked position to securely lock the terminals in their corresponding cavities, the connector further comprising a slide-lock coupling mechanism to assist coupling of the connector to a complementary connector by movement of the slide-lock member from an open position where the complementary connector is received to a closed position where the connectors are coupled, characterized in that the slide-lock coupling member and secondary locking member have interengageable shoulder and latch members that engage each other when the secondary locking member is in the preassembly position to prevent movement of the slide-lock member (10) for coupling, the latch members being disengaged when the secondary locking member is in the fully locked position to allow movement of the slide-lock member for coupling.
Claim 3
Dependent Claim
25 words
The connector of claim 1 characterized in that the slide-lock member is in the closed position when the shoulder and latch members engage each other.
Claim 4
Dependent Claim
43 words
The connector of claim 1 characterized in that the slide-lock member comprises side walls having camming slots therein for receiving complementary studs of the complementary connector, the camming slots for drawing the complementary connector towards the connector by camming engagement with the studs.
Claim 5
Dependent Claim
28 words
The connector of claim 3 characterized in that the shoulder is on the side wall of the slide-lock member, and the latch member on the secondary locking member.
Claim 6
Dependent Claim
27 words
The connector of claim 1 characterized in that the secondary locking member is mountable over a mating end of a terminal receiving section of the connector housing.
Claim 7
Dependent Claim
94 words
The connector of claim 5 characterized in that the connector housing comprises resilient locking lances with protrusions engageable with the terminals for locking thereof within the cavities, the locking lances having outer surfaces, wherein the secondary locking member has wall portions engaged against the outer surfaces when in the fully locked position, and disengaged from the outer surfaces when in the preassembled position to respectively, allow resilient biasing of the lances for insertion of the terminals in the cavities, and secure locking of the terminals therein by preventing outward resilient biasing of the lances.
Claim 8
Dependent Claim
41 words
The connector of claim 1 characterized in that the slide-lock member comprises a recess extending orthogonally to the longitudinal direction and adjacent the shoulder, for receiving the latch member thereagainst to allow movement of the slide-lock member in the orthogonal direction.
Claim 9
Dependent Claim
40 words
The connector of claim 7 characterized in that the recess comprises notches at the open and closed positions for holding the slide-lock member at those positions with a certain limited force, by engagement with a protrusion of the latch member.
Claim 10
Dependent Claim
24 words
The connector of claim 1 characterized in that the latch member is a resilient beam with a protrusion thereon for engagement with the shoulder.
Claim 11
Dependent Claim
38 words
The connector of claim 3 characterized in that the secondary locking member is positioned between the side walls but spaced therefrom by a gap for receiving the shroud of the complementary connector on which the studs are attached.
Claim 12
Dependent Claim
42 words
The connector of claim 10 characterized in that the side walls extend from opposing ends of a base wall that serves as a depressor/puller for actuation of the slide-lock movement, such movement being orthogonal to the direction of coupling of the connector.
