  • interference avoidance surfaces 83, 93 are formed on the inner conductor tube portion 82 and the outer conductor tube portion 92, respectively, so that the tip edges of the inner conductor tube portion 82 and the outer conductor tube portion 92 are effectively prevented from coming into contact with the outer conductor 90 or the inner conductor 80.
  • the inner conductor tube portion 82 may approach the mating dielectric 42.

  • the outer circumference of the portion narrowed toward the inner circumference serves as the interference avoidance surface 193, which corresponds to the interference avoidance surface 93.
  • the slits 183a, 193a can be used to widen the tip periphery of the inner conductor tube portion 182 and the outer conductor tube portion 192 toward the outer circumference or narrow it toward the inner circumference, making it easier to incline the interference avoidance surfaces 183, 193 at a large angle and over a wide range, and as a result, it is easier to set a large amount of avoidance for interference avoidance.
  • the widths S1, S2 of the slits 183a, 193a are smaller than the width W1 of the inner elastic piece 56 and the width W3 of the outer elastic piece 66.

Therefore, even if the tip periphery of the tubular portions 82, 92 approaches the mating inner conductor 50 or the mating outer conductor 60, contact with the mating inner conductor 50 or the mating outer conductor 60 is suppressed. As a result, even if the coaxial connector 70 is inclined with respect to the central axis X of the coaxial connector for board 40, the coaxial connector 70 is unlikely to interfere with the coaxial connector for board 40.
  • the interference avoidance surfaces 83, 93 extend in an annular shape along the tip periphery of the tubular portions 82, 92, the coaxial connector 70 is unlikely to interfere with the coaxial connector for circuit board 40, regardless of the direction in which the coaxial connector 70 is tilted relative to the central axis X of the coaxial connector for circuit board 40.

  • the widths S1 and S of the slits 83b, 183a and 193a are smaller than the width W1 of the inner elastic piece 56 or the width W2 of the outer elastic piece 66, the inner elastic piece 56 or the outer elastic piece 66 will not fit into the slits 83b, 183a and 193a, but will be smoothly guided to the inner circumference of the inner conductor tube portion 82 and 182 or the outer circumference of the outer conductor tube portion 192.
  • an inner interference avoidance surface 83 is formed on the inner peripheral portion of the tip periphery of the inner conductor tube portion 82, so even if the inner conductor 80 is significantly tilted relative to the mating inner conductor 50, the inner peripheral portion of the tip periphery of the inner conductor tube portion 82 is unlikely to interfere with the mating inner conductor 50.
  • an external interference avoidance surface 93 is formed on the outer peripheral portion of the tip periphery of the outer conductor tube portion 92, so even if the outer conductor 90 is significantly tilted relative to the mating outer conductor 60, the outer peripheral portion of the tip periphery of the outer conductor tube portion 92 is unlikely to interfere with the mating outer conductor 60.
  • the mating inner conductor 50 has an inner elastic piece 56

In this case, even if the coaxial connector 70 is tilted relative to the coaxial connector 40 for the board, the interference avoidance surfaces 83, 93 make it difficult for the coaxial connector 70 to interfere with the coaxial connector 40 for the board.
  • the mating dielectric 42 has an annular recess 47, even if the coaxial connector 70 is connected to the coaxial connector for circuit board 40 in an inclined state, the outer conductor tube portion 92 is unlikely to interfere with the mating dielectric 42.
