Therefore, during the fitting process of the first housing 11 and the second housing 61, the worker does not need to rotate the lever 14, which reduces the workload.
  • the detachment cam surface 57 is formed on the upper groove surface of the detachment cam groove portion 58, the cam pins 37, 68 are pressed downward by the detachment cam surface 57, and the second housing 61 can be smoothly detached downward from the first housing 11.
  • the operating part 50 which protrudes above the first housing 11, is operated, providing excellent operability.
  • the plate cam pin 37 when the plate cam pin 37 is placed in the inspection groove 44, the plate body 34 reaches the inspection position, and the continuity of the first terminal metal fitting 12 can be inspected.
  • the lever 14 rotates, the plate cam pin 37 moves from the protection groove 45 to the fitting groove 46, the first housing 11 and the second housing 61 are fitted, and the plate body 34 can reach the fitting position.
  • the assembly groove 43, the inspection groove 44, the protection groove 45, and the fitting groove 46 are formed in succession, so that the plate cam pin 37 does not enter the assembly groove 43 when moving from the protection groove 45 to the fitting groove 46. Therefore, the plate cam pin 37 can move smoothly from the protection groove 45 to the fitting groove 46.
  • the tab 19 is properly protected by the plate body 34 in the protection position.
  • the plate cam pin 37 can be prevented from entering the branch groove portion 51 when the plate cam pin 37 moves from the protection groove portion 45 to the fitting groove portion 46.
  • the cam pins 37, 68 which are the combination of the housing cam pin 68 and the plate cam pin 37, are arranged in the cam groove 42.
  • the housing cam pin and the plate cam pin may simply be arranged side by side in the cam groove.
  • a configuration in which only the housing cam pin is arranged in the cam groove may be used.
  • the housing cam pin may be configured to come into contact with the release cam surface and be pressed by the release cam surface.
  • the pair of levers 14 are supported separately from each other on the first housing 11.
  • the first housing may be configured to support one lever having a pair of cam plate portions connected by a connecting portion.
  • the first housing may be configured to support a lever consisting of only one cam plate portion.
  • the cam groove 42 has the floating groove portion 47 between the fitting groove portion 46 and the removal groove portion 48.
  • the cam groove does not have a floating groove portion, and the fitting groove portion and the removal groove portion may be formed continuously in this order.
