Abstract
Abstract The present connector has a structure which makes it possible to execute a step of mounting a wire holder serving also as a cover member to a housing main body and a step of connecting electrical wires to their respective pressure contact terminals in one operation to simplify the assembly thereof and is thus suitable for mass production. A housing main body supports the pressure contact edges of the pressure contact terminals in an upwardly bent position with respect to the male tabs of the pressure contact terminals. A wire holder holds a plurality of electric wires provisionally in such a manner that the wires can be pressure contacted with their respective pressure contact edges, and serves also as a cover member to close the upper opening of the housing main body, through which opening the pressure contact edges are exposed. By mounting the wire holder to the housing main body, the wires can be connected to the pressure contact terminals. Also, the wires are previously bent and provisionally held by the wire holder and a spacer cooperable with the wire holder to thereby prevent the wires from being removed backwardly.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
207 words
A connector, in which a plurality of pressure contact terminals are stored, for connecting a partner connector with the pressure contact terminals in an electrically energizable manner, said connector comprising: a housing main body for storing said pressure contact terminals in parallel to one another, said housing main body being opened in an upper surface thereof so as to expose said pressure contact terminals in part; a wire holder including a plurality of wire receiving chambers for retaining a plurality of electric wires therein and also serving as a cover member to close said opened upper surface of said housing main body, said wires being received in said wire receiving chambers and extending in a first direction, said wire holder including a spacer insertion portion extending in a second direction perpendicular to said first direction; and a spacer including a plurality of wire receiving holes and being received in said spacer insertion portion, said spacer being movable from a provisionally retained position, at which said holes are respectively aligned with said wire receiving chambers such that said wires can be inserted therein, to a completely retained position, at which said holes are at least partially misaligned with said chambers thereby bending said wires in said second direction.
Claim 2
Dependent Claim
207 words
A connector, in which a plurality of pressure contact terminals are stored, for connecting a partner connector with the pressure contact terminals in an electrically energizable manner, said connector comprising: a housing main body for storing said pressure contact terminals in parallel to one another, said housing main body being opened in an upper surface thereof so as to expose said pressure contact terminals in part; a wire holder including a plurality of wire receiving chambers for retaining a plurality of electric wires therein and also serving as a cover member to close said opened upper surface of said housing main body, said wires being received in said wire receiving chambers and extending in a first direction, said wire holder including a spacer insertion portion extending in a second direction perpendicular to said first direction; and a spacer including a plurality of wire receiving holes and being received in said spacer insertion portion, said spacer being movable from a provisionally retained position, at which said holes are respectively aligned with said wire receiving chambers such that said wires can be inserted therein, to a completely retained position, at which said holes are at least partially misaligned with said chambers thereby bending said wires in said second direction.
Claim 3
Dependent Claim
68 words
A connector as set forth in claim 1, wherein each of said pressure contact terminals includes an electric contact portion fittable with said partner connector and a pressure contact edge into which each of said wires is pressure inserted, and said pressure contact edge is bent-formed with respect to said electric contact portion in a manner to project toward said opened upper surface of said housing main body.
Claim 4
Dependent Claim
26 words
A connector as set forth in claim 1, wherein said wire holder includes a wire escape portion for receiving at least some of said bent wires.
Claim 5
Dependent Claim
190 words
A connector, in which a plurality of pressure contact terminals are stored, for connecting a partner connector with the pressure contact terminals in an electrically energizable manner, said connector comprising: a housing main body for storing said pressure contact terminals in parallel to one another, said housing main body being opened in an upper surface thereof so as to at least partially expose said pressure contact terminals; a wire holder, securable to said housing main body, capable of holding a plurality of electric wires provisionally and also serving as a cover member to close said opened upper surface of said housing main body, said wire holder having wire chambers in which said wires are received extending in a first direction; a bending means cooperable with said wire holder to bend said wires in a second direction perpendicular to said first direction, wherein said wire holder is secured to said housing main body to thereby be able to pressure-insert said wires into respective said pressure contact terminals, wherein said bending means includes a plurality of bending projections which are respectively fixedly secured to said housing main body and said wire holder.
Claim 6
Dependent Claim
190 words
A connector, in which a plurality of pressure contact terminals are stored, for connecting a partner connector with the pressure contact terminals in an electrically energizable manner, said connector comprising: a housing main body for storing said pressure contact terminals in parallel to one another, said housing main body being opened in an upper surface thereof so as to at least partially expose said pressure contact terminals; a wire holder, securable to said housing main body, capable of holding a plurality of electric wires provisionally and also serving as a cover member to close said opened upper surface of said housing main body, said wire holder having wire chambers in which said wires are received extending in a first direction; a bending means cooperable with said wire holder to bend said wires in a second direction perpendicular to said first direction, wherein said wire holder is secured to said housing main body to thereby be able to pressure-insert said wires into respective said pressure contact terminals, wherein said bending means includes a plurality of bending projections which are respectively fixedly secured to said housing main body and said wire holder.
Claim 7
Dependent Claim
74 words
A connector as set forth in claim 4, wherein said housing main body is formed as a multi-stage structure in which a plurality of pressure contact terminals are arranged on top of one another and the rear end portions of respective stages of said housing main body are respectively formed in a stepped shape in order to be able to expose the respective pressure contact edges of said pressure contact terminals in said stages.
Claim 8
Dependent Claim
