Connector unit
In a connector unit including a connector and a connector cover that fits on the connector, the connector includes a guide means that guides electric wires in one direction, while the connector cover includes a pressing means that presses on and deforms the guide means so as to restrict the movement of the electric wires that are guided by the guide means, whereby the electric wires that are pulled out of the connector are oriented in the one direction in which the electric wires are guided by the guide means.
1. An electrical connector unit comprising:
a connector including a connector housing that accommodates a terminal that is attached to an electric wire; and
a connector cover that is assembled to an electric wire pull-out opening in the connector housing, the connector cover configured to receive the electric wire that is pulled out of the connector housing in a pull-out direction;
another connector including a connector housing that accommodates a terminal that is attached to another electric wire;
another connector cover configured to receive the another electric wire, wherein:
the connector cover has a bottomed tubular shape, and includes two electric wire passage openings formed in side walls of the connector cover, the two electric wire passage openings constituting an entrance or an exit for the another electric wire that is laid out from the another connector cover, the two electric wire passage openings allowing the another electric wire to extend through an entirety of the connector cover in a lay-out direction perpendicular to the pull-out direction,
the two electric wire passage openings further configured to guide the electric wire that is pulled out of the connector housing in the lay-out direction,
each of the two electric wire passage openings having a first opening end and a second opening end in the pull-out direction, wherein the first opening end is larger in a width direction perpendicular to the lay-out direction and the pull-out direction than the second opening end, and
the another connector cover adjacent and parallel to the connector cover, configured to guide the another electric wire in the lay-out direction to the connector cover.
2. The electrical connector unit according to claim 1 , wherein:
the connector cover is axially symmetrical, and
the connector housing has an axially symmetrical shape in which an axis of an electric wire pull-out-side end portion of the connector housing coincides with an axis of an opening-side end portion of the connector cover, enabling the electric wire pull-out-side end portion to fit into the opening-side end portion.
3. The electrical connector unit according to claim 2 , wherein:
the electrical connector unit further has an axial rotation locking portion that locks the connector cover and the connector housing at a plurality of locations, and
when the connector cover is engaged with the connector unit, the connector cover is rotatable about the axis of the axial rotation locking portion relative to the connector housing.
4. The electrical connector unit according to claim 2 , wherein:
in the connector cover, an external shape of a section orthogonal to the axis of the opening-side end portion is square, and
in the connector housing, an external shape of a section orthogonal to the axis of the electric wire pull-out-side end portion is square so that the electric wire pull-out-side end portion of the connector housing can fit in the opening-side end portion of the connector cover.
5. The electrical connector unit according to claim 1 , wherein the connector is configured to be insertable into the connector cover such that the connector cover overlaps at least a portion of the connector in each of the pull-out direction and the width direction,
wherein the first opening end of each of the two electric wire passage openings is closer to a closed end of the connector cover and the second opening end of each of the two electric wire passage openings is closer to an open end of the connector cover.
6. The electrical connector unit according to claim 1 , wherein an insertion end of the connector includes at least one engaged member configured to engage with engageable openings of the connector cover, the engageable openings disposed closer to the second opening end of the two electric wire passage openings than to the first opening end of the two electric wire passage openings.
7. The electrical connector unit according to claim 6 , wherein the engageable openings are disposed at a same position, in the pull-out direction, as the second opening end of the two electric wire passage openings.
