Electrical connector

1. An electrical connector comprising:

a tubular housing having a partition wall extending in a direction perpendicular to a longitudinal direction of the tubular housing, the partition wall being located at a substantially center in the longitudinal direction; and

a bus bar embedded in the partition wall of the housing in a state of penetrating the partition wall in the longitudinal direction,

wherein a through hole is formed at a position of the bus bar at which the bus bar is embedded in the partition wall;

wherein a part of the partition wall is filled in the through hole; and

wherein a range of the partition wall away from the position at which the bus bar is embedded in the partition wall has a thinned part.

2. The electrical connector according to claim 1 , wherein a rib extending in the direction perpendicular to the longitudinal direction is provided on the thinned part of the partition wall.

3. The electrical connector according to claim 2 , wherein the through hole and the rib are disposed in the same plane.

4. The electrical connector according to claim 1 , wherein a thickness of the thinned part of the partition wall in the longitudinal direction is a half of a thickness of a hole periphery portion of the partition wall in the longitudinal direction, the hole periphery portion being located at a position having a part of the partition wall at which the bus bar is embedded.

5. The electrical connector according to claim 4 , wherein the thinned part is continuously connected to the hole periphery portion through a stepped part of the partition wall.

6. The electrical connector according to claim 1 , wherein a central tubular portion that connects a first tubular portion and a second tubular portion of the tubular housing has an inner periphery,

wherein an insert hole through which the bus bar passes is formed in the partition wall, and a periphery of the insert hole is a hole periphery portion having a first thickness, and

wherein a portion between the outer periphery of the hole periphery portion and the inner periphery of the central tubular portion is thinned by a depth of a second thickness so as to surround the hole periphery portion to thereby form a thinning removal portion of the thinned part.

7. The electrical connector according to claim 6 , wherein the partition wall has the hole periphery portion, and a thinning residue portion left after the thinning, and a third thickness of the thinning residue portion is a value obtained by subtracting a depth the second thickness of the thinning removal portion from the first thickness of the hole periphery portion.

8. The electrical connector according to claim 6 , wherein a volume of the partition wall is reduced by the volume of the thinning removal portion.

9. An electrical connector comprising:

a tubular housing having a partition wall extending in a direction perpendicular to a longitudinal direction of the tubular housing, the partition wall being located at a substantially center in the longitudinal direction; and

a bus bar embedded in the partition wall of the housing in a state of penetrating the partition wall in the longitudinal direction,

wherein a through hole is formed at a position of the bus bar at which the bus bar is embedded in the partition wall,

wherein a part of the partition wall is filled in the through hole,

wherein a range of the partition wall away from the position at which the bus bar is embedded in the partition wall has a thinned part, and

wherein a rib extending in the direction perpendicular to the longitudinal direction is provided on the thinned part of the partition wall.
