Abstract

A joint connector 10 is provided with a joint terminal 12, and a housing 13 configured to accommodate the joint terminal 12. The joint terminal 12 includes a plurality of branch portions 16, a plurality of wire connecting portions 19 respectively continuous with the plurality of branch portions 16 and to be connected to wires 11, and a coupling portion 15 electrically connecting the plurality of branch portions 16 by coupling the plurality of branch portions 16. The wire connecting portion 19 includes a connecting piece having a contact surface configured to contact the wire 11 and a pressing portion 17 configured to press the connecting piece against the wire 11 by coming into contact with the connecting piece.

First claim

What is claimed is:

1. A joint connector, comprising:
a joint terminal; and
a housing configured to accommodate the joint terminal,
the joint terminal including a plurality of branch portions, a plurality of wire connecting portions respectively continuous with the plurality of branch portions and to be connected to wires, and a coupling portion electrically connecting the plurality of branch portions by coupling the plurality of branch portions,
wherein:
the wire connecting portion includes a connecting piece having a contact surface configured to contact the wire and a pressing portion configured to press the connecting piece against the wire by coming into contact with the connecting piece,
the pressing portion has a tubular shape and is externally fit to a region of the wire connecting portion where the connecting piece is provided,
the pressing portion includes a contact portion configured to press the connecting piece against the wire by coming into contact with the connecting piece,
the contact portion projects inward from an inner surface of a wall of the pressing portion, and
the contact portion comes into contact with the connecting piece when the pressing portion is slid to a pressing position where the pressing portion presses the connecting piece against the wire.

2. The joint connector of claim 1 , wherein the pressing portion moves between the pressing position and a releasing position where the pressing portion does not press the connecting piece.

3. The joint connector of claim 2 , wherein a jig contact portion is provided to project on the pressing portion, and the pressing portion is moved from the releasing position to the pressing position by being pressed by a jig with the jig contact portion held in contact with the jig.

4. The joint connector of claim 2 , wherein:
a holder is mounted on the housing, and
the holder includes an engaging portion configured to restrict a movement of the pressing portion at the pressing position to the releasing position by engaging the pressing portion with the holder mounted on the housing.

5. The joint connector of claim 1 , wherein the plurality of wire connecting portions are disposed on opposite ends in a longitudinal direction of the branch portions.

6. The joint connector of claim 1 , wherein:
the coupling portion includes a coupling portion folded portion folded in a longitudinal direction of the coupling portion and a first coupling portion and a second coupling portion delimited by the coupling portion folded portion, and
the first and second coupling portions are folded to overlap.

7. The joint connector of claim 1 , wherein:
the plurality of branch portions include first branch portions branched on one side of the coupling portion and second branch portions branched on the other side of the coupling portion, and
the second branch portions are folded to extend in the same direction as an extending direction of the first branch portions.
