[0003] In the prior art, a connector typically includes a housing and a plurality of terminals. The plurality of terminals are inserted into the housing and arranged in a row in the lateral direction of the housing. The terminals have crimp portions exposed outside the housing. The crimp portions are configured to be crimped to a cable. In the prior art, the crimp portions of the plurality of terminals are typically arranged in a row in the lateral direction of the housing such that the spacing between the crimp portions of two adjacent terminals is equal to the pitch between the two adjacent terminals.
