Joint connector

1. A joint connector for shorting wires to each other by electrically connecting wire-side terminals respectively mounted on ends of the wires to each other, comprising:

a shorting member made of a conductive material, the shorting member integrally including a base extending in a shorting direction and shorting-side terminal projecting from the base in a terminal projecting direction intersecting the shorting direction, each shorting-side terminal portion being shaped to fit to each wire-side terminal; and

an insulating housing having a shorting member holding portion for holding the shorting member;

wherein the shorting member holding portion includes first and second clamping portion divided from each other in a clamping direction perpendicular to the shorting direction and the terminal projecting direction and capable of clamping the shorting member from both sides in the clamping direction, and a clamping/fixing portion for constraining the first and second clamping portions to each other to fix relative positions of the first and second clamping portions at clamping positions where the first and second clamping portions clamp the shorting member from both sides in the clamping direction, and at least one of the first and second clamping portions is a constraining clamping portion including a shorting member constraining portion for constraining the shorting member to restrict a relative displacement of the shorting member in the terminal projecting direction with respect to the first and second clamping portion at the clamping position.

2. The joint connector of claim 1 , wherein the first and second clamping portions include clamping surfaces facing each other in the clamping direction at the clamping positions, and the shorting member constraining portion includes constraining protrusions projecting from the clamping surface of the constraining clamping portion toward the mating clamping portion.

3. The joint connector of claim 2 , wherein the constraining protrusions include those for constraining the base portion in a direction parallel to the terminal projecting direction by being located at positions between adjacent ones of the plurality of shorting-side terminal portions and near the base and constraining the shorting-side terminal portions in a direction perpendicular to the terminal projecting direction.

4. The joint connector claim 2 , wherein the shorting member includes a through hole penetrating through the base thereof in a direction parallel to the clamping direction, and the constraining protrusions include a through hole inserting protrusion to be inserted into the through hole in the direction parallel to the clamping direction at the clamping position.

5. The joint connector of claim 1 , further comprising a plurality of the shorting members arranged in a direction parallel to the clamping direction, wherein the shorting member holding portion includes the first and second clamping portions for each shorting member.

6. The joint connector of claim 5 , wherein the shorting member holding portion includes a common clamping portion interposed between mutually adjacent ones of the plurality of shorting members and commonly used as the first clamping portion for one of the mutually adjacent shorting members and as the second clamping portion for the other shorting member.

7. The joint connector of claim 5 , wherein the clamping/fixing portion collectively fixes relative positions of the first and second clamping portions for clamping each of the shorting members at the clamping positions by coupling both outer clamping portions located on both outer sides in a direction parallel to the clamping direction.

8. The joint connector of claim 7 , wherein the clamping/fixing portion is formed to be integrally connected to one of the both outer clamping portions.
