  • the counterpart waveguide 191 is bent to 90 degrees in the counterpart housing 111, and its rear end is short enough not to protrude from the side surface 111 c of the counterpart housing 111.
  • the rear end may be connected to a high-frequency generator (not shown) attached to the side surface 111c.
  • the connector 1 includes the housing 11 to which the waveguide 91 is connected, and the holding sleeve 81 that is attached to the housing 11 and holds the waveguide 91.
  • the waveguide housing hole 15 for housing the waveguide body 91, and the holding sleeve 81 is interposed between the waveguide body 91 and the housing 11 and compressed in the waveguide body housing hole 15. Holds the waveguide 91.
  • the connector 1 is easy to manufacture, has a simple configuration, is low in cost, and is small in size, but can be highly waterproof. In addition, it is easy to handle and can be connected in a state where the waveguides are accurately aligned, so that reliability can be improved.
  • the housing 11 is a plane orthogonal to the axial direction of the waveguide 91 and includes a front surface 11a facing the front surface 111a of the counterpart housing 111 of the counterpart connector 101.
  • the holding sleeve 81 is made of a dielectric material.
  • the front end surface 91a of the waveguide 91 is covered with a dielectric material and is located behind the front surface 11a, and the front surface 83a of the holding sleeve 81 is flush with the front surface 11a. This enables efficient transmission of electromagnetic waves between the connector 1 and the counterpart connector 101.
  • the front end surface 91a of the waveguide 91 is covered with a dielectric material, moisture does not enter and the waveguide 91 is not adversely affected.
  • the holding sleeve 81 includes a cylindrical main body portion 82, a flange portion 83 connected to the front end of the main body portion 82, and a center hole 84 extending in the front-rear direction. It includes a flange accommodating portion 15a that opens to the front surface 11a, and a sleeve holding portion 15b that is connected to the rear end of the flange accommodating portion 15a, and the waveguide 91 is accommodated in the center hole 84 in the waveguide accommodating hole. 15, the flange portion 83 holds the waveguide 91 in the flange receiving portion 15 a, and at least a part of the main body portion 82 holds the waveguide 91 in the sleeve holding portion 15 b. Thereby, the waveguide 91 can be reliably held. In addition, since the outer peripheral surface of the waveguide 91 is in close contact with the inner surface of the center hole 84 without any gap, entry of moisture is reliably prevented.
  • the holding sleeve 81 includes a protruding ridge 85 protruding outward from the outer peripheral surface 82a of the main body 82, and the protruding ridge 85 is compressed by the inner surface of the sleeve holding portion 15b.
  • friction with the outer peripheral surface of the waveguide 91 can be increased, and displacement of the waveguide 91 in the front-rear direction can be effectively prevented.
  • the housing 11 includes a holding portion 14 in which the waveguide housing hole 15 is formed, and the holding sleeve 81 has a flange portion 86 that protrudes outward from the outer peripheral surface 82a of the main body portion 82 obliquely forward.
  • the collar portion 86 abuts on the rear surface 14b of the holding portion 14.
  • the present invention can be applied to a connection device.
