Joint connector and method for identifying bus bar pattern in joint connector
View Patent ↗A joint connector includes a bus bar and a housing. The bus bar juxtaposes plural tab pieces to be connected to mating terminals. The housing has a bus bar accommodating part accommodating the bus bar, and includes plural terminal receiving chambers for receiving the mating terminals. The housing is formed with plural continuity check holes at a back end of the housing so as to expose a back end of the bus bar. In a case where the plural bus bars are accommodated in the bus bar receiving parts, at least one of the continuity check holes is positioned between the adjacent bus bars, and the at least one of the continuity check holes is formed in a resin-sealed part filled with an insulating resin material.
1. A joint connector, comprising:
a bus bar for juxtaposing plural tab pieces to be connected to mating terminals, and
a housing, having a bus bar accommodating part accommodating the bus bar, including plural terminal receiving chambers for receiving the mating terminals, and formed with plural continuity check holes at a back end of the housing so as to expose a back end of the bus bar,
wherein, in a case where the plural bus bars are accommodated in the bus bar accommodating parts, at least one of the continuity check holes is positioned between the adjacent bus bars, and the at least one of the continuity check holes is filled with an insulating resin material to be a resin-sealed part.
2. The joint connector according to claim 1 , wherein
the continuity check holes are arranged in a pitch so as to be arranged at middle between the adjacent terminal receiving chambers.
3. A method for identifying a bus bar pattern in the joint connector described in claim 1 , comprising:
preparing plural continuity test pins, disposed at positions each of which corresponding to the resin-sealed part provided in each of bus bar patterns;
preparing plural continuity pins, disposed at positions each of which corresponding to the continuity check holes which is not formed in the resin-sealed part in any bus bar patterns;
executing continuity tests for each of the continuity test pins; and
identifying the bus bar pattern based on arrangement of the continuity test pins which become non-conducting to the bus bar.
