Connector with protrusions near contact pieces

A connector comprising:

• a plurality of terminals configured to connect to electric wires;
• a bus bar configured to electrically connects the plurality of terminals to one another;
• and
• a housing that comprises a plurality of terminal receiving chambers and a bus bar receiving chamber, the terminal receiving chambers configured to receive and position the plurality of terminals therein, and the bus bar receiving chamber configured to receive the bus bar,
• wherein the bus bar comprises a plurality of contact pieces, a coupling portion, and support portions, the contact pieces being brought into contact with elastically contactable contact point portions provided in the plurality of terminals, the plurality of contact pieces extending in one and the same direction, the coupling portion coupling the plurality of contact pieces, the support portions extending in an extension direction of the plurality of contact pieces from both end portions of the coupling portion in its widthwise direction respectively, protrusions being provided in the support portions and being configured to be locked to the bus bar receiving chamber,
• wherein a position where the plurality of contact pieces make contact with the contact point portions of the plurality of terminals and a position where the protrusions are locked to the bus bar receiving chamber are set to be aligned with each other in a longitudinal direction of the housing such that the protrusions are inserted into the housing as far along the longitudinal direction as at least a portion of the plurality of contact pieces in contact with the contact point portions,
• wherein the position, where the plurality of contact pieces make contact with the contact point portions of the plurality of terminals, is a first position,
• wherein the position, where the protrusions are locked to the bus bar receiving chamber, is a second position,
• wherein, in a cross-section through the housing and perpendicular to the longitudinal direction, the first position and the second position are adjacent to each other in the cross-section,
• wherein, of all parts of the bus bar, the tip ends are inserted furthest into the housing, and
• wherein of all the parts of the bus bar, the end, of the bus bar opposite the tip ends, is inserted least into the housing and is also furthest from the tip ends.
