Abstract

A connector has a conductive member attaching portion to which an end portion of a conductive member is to be attached, and a holder portion provided with an insertion hole into which the conductive member is inserted, and a fitting hole into which the conductive member attaching portion is fitted, the fitting hole being in communication with the insertion hole, the holder portion being configured to hold the conductive member attaching portion. The holder portion is provided with engaged portions with which engaging portions, which are provided at respective ends of the conductive member in the width direction, engage. The conductive member attaching portion is provided with a closing portion configured to close a part of the insertion hole. When the conductive member attaching portion has been fitted into the holder portion, the closing portion closes a part of the insertion hole with the engaging portions engaged with the engaged portions.

First claim

What is claimed is:

1. An electrical connector to which a conductive member configured as a flexible cable or a flexible board having a plurality of conductors is to be connected, comprising:
a conductive member attaching portion configured such that an end portion of the conductive member is to be attached to the conductive member attaching portion; and
a holder portion configured to hold the conductive member attaching portion, the holder portion being provided with an insertion hole into which the conductive member is to be inserted, and a fitting hole configured such that the conductive member attaching portion, to which the end portion of the conductive member inserted in the insertion hole has been attached, is fitted into the fitting hole, the fitting hole being in communication with the insertion hole,
wherein the holder portion is provided with engaged portions configured such that engaging portions are engaged with the engaged portions of the holder portion, wherein each of the engaging portions is provided in a part of each end of the end portion of the conductive member and be extended outwardly in a width direction,
wherein the conductive member attaching portion is provided with a closing portion
wherein the closing portion closes a part of the insertion hole with the engaging portion engaged with the engaged portion when the conductive member attaching portion, to which the end portion of the conductive member inserted in the insertion hole has been attached, is fitted into the holder portion, and
wherein the closing portion closes a part of the insertion hole in a state of being fitted into the insertion hole.

2. The electrical connector according to claim 1 ,
wherein the conductive member attaching portion is provided with a casing-like portion that demarcates an insertion slot into which the end portion of the conductive member is inserted, and
the end portion of the conductive member is attached to the conductive member attaching portion by being inserted into the insertion slot.

3. The electrical connector according to claim 1 ,
wherein the insertion hole in the holder portion includes an engaging portion passage region that is a region at each end of the insertion hole in the width direction of the insertion hole, the engaging portion passage region through which the engaging portion passes when the conductive member is inserted into the insertion hole and passes through the insertion hole, and
when the conductive member attaching portion, to which the end portion of the conductive member inserted in the insertion hole has been attached, has been fitted into the holder portion, the closing portion closes at least the engaging portion passage region in the insertion hole with the engaging portion engaged with the engaged portion.

4. The electrical connector according to claim 3 ,
wherein the insertion hole of the holder portion includes a conductive member passage region through which the conductive member passes when being inserted into the insertion hole, and a conductive member arrangement region in which the conductive member is arranged in a state of being disposed so as to be shifted from the conductive member passage region after the conductive member has been inserted in the insertion hole,
the conductive member passage region includes the engaging portion passage region, and
when the conductive member attaching portion, to which the end portion of the conductive member inserted in the insertion hole has been attached, has been fitted into the holder portion, the closing portion closes the conductive member passage region in the insertion hole with the engaging portion engaged with the engaged portion.

5. The electrical connector according to claim 1 ,
wherein the conductive member attaching portion is provided with a bending restriction portion configured to hold the end portion of the conductive member attached to the conductive member attaching portion in a front-back face direction of the conductive member in a center part in the width direction of the conductive member attaching portion, the bending restriction portion restricting bending deformation of the conductive member.

6. An electrical connection device including the electrical connector according to claim 1 , comprising:
a first connector configured as the connector; and
a second connector to which the first connector is connected,
wherein the second connector includes:
a plurality of terminals configured to be electrically connected to the plurality of conductors in the conductive member attached to the conductive member attaching portion; and
a housing configured to hold the plurality of terminals, the housing to which the conductive member attaching portion is fitted and with which the holder portion is engaged.

7. The electrical connection device according to claim 6 ,
wherein the housing is provided with a leading end exposing portion configured as a window-like part or a cutout part so as to expose a part of a leading end portion of the conductive member attaching portion to the outside, with the conductive member attaching portion fitted to the housing, and with the plurality of terminals electrically connected to the plurality of conductors in the conductive member.

8. The electrical connection device according to claim 6 ,
wherein the conductive member attaching portion is provided with
a projecting portion provided so as to project toward a leading end side of the conductive member attaching portion at each end of the conductive member attaching portion in the width direction, the projecting portion being guided along and fitted into a guide groove provided in the housing, when the conductive member attaching portion is fitted to the housing; and
an upper face portion and a lower face portion configured to sandwich the end portion of the conductive member attached to the conductive member attaching portion in a front-back face direction of the conductive member, and
a projecting length of the projecting portion relative to either the upper face portion or the lower face portion is set to be longer than a projecting length of the projecting portion relative to the other one.
