Claims

[Scope of utility model registration request]

In a connector comprising a plurality of U-groove terminals and an insulator housing housing the terminals, the U-groove terminals are arranged in two rows in a staggered manner, and each U-groove terminal is arranged in two rows in a staggered manner.
A protruding piece having an appropriate groove width is protruded from the housing at a position facing the groove portion of the groove terminal, and is configured as a strain relief in three rows at the center and both sides between the opposing sides of the staggered U-groove terminal. The strain relief structure is characterized in that the protruding piece disposed in the center is shared by one side of the U-groove terminal having two rows.
