  • the coaxial connector 1 when the coaxial connector 1 is detached from the counterpart receptacle 201, the user needs to pull the sleeve 30 upward with a force larger than the difference between the force F4 and the force F3. Thereby, the resultant force of the force F3 generated by the coil spring 22 and the user's force is larger than the force F4 generated by the magnet 27, and the disk 21 and the yoke 23 are separated. Then, the coaxial connector 1 is detached from the counterpart receptacle 201.
  • the inventor of the present application designed the magnitude of the force F3 to be 7N and the magnitude of the force F4 to be 9N. Thereby, the user can detach the coaxial connector 1 from the counterpart receptacle 201 by applying a force of 2N or more.
  • the coaxial connector 101 has a problem in durability.
  • the housing 25 is pulled up by the magnet 27 in order to maintain the second state in which the counterpart receptacle 201 is mounted. Therefore, when the coaxial connector 1 is attached to or detached from the counterpart receptacle 201, the housing 25 and the sleeve 30 hardly slide, so that no shaving is generated between the housing 25 and the sleeve 30. Therefore, even if the coaxial connector 1 is repeatedly attached to and detached from the counterpart receptacle 201, smooth sliding of the sleeve 30 is not hindered. As described above, according to the coaxial connector 1, higher durability can be obtained as compared with the coaxial connector 101.
  • this inventor produced the coaxial connector 1,101 and performed the endurance test of this coaxial connector 1,101.
  • the conventional coaxial connector 101 when wax is applied between the protrusion 132 b and the housing 125, a failure occurs after about 10,000 attachments / detachments, and no wax is applied between the protrusion 132 b and the housing 125. In this case, a problem occurred after attaching and detaching about 300 times.
  • the coaxial connector 1 can withstand attachment / detachment to the counterpart receptacle 201 more than 20000 times. From the above, it can be seen from the durability test that the coaxial connector 1 has higher durability than the coaxial connector 101.
  • the disk 21 and the yoke 23 are in contact with each other and the disk 21 and the magnet 27 are in contact with each other in the second state where the disk 21 is attached to the counterpart receptacle 201. Absent. As a result, the housing 25 and the sleeve 30 are stably adsorbed as described below.
  • the disk 21 and the yoke 23 are made of a ferromagnetic material. Therefore, as shown in FIG. 8B, when the disk 21 and the yoke 23 come into contact with each other, a magnetic flux as indicated by an arrow ⁇ is generated. In this case, the disk 21 and the yoke 23 are most strongly attracted when the magnet 27 is in contact with the disk 21. Therefore, it is preferable that the disk 21 and the yoke 23 are in contact with each other, and that the disk 21 and the magnet 27 are in contact with each other.
  • the suction force between the disk 21 and the yoke 23 is extremely small compared to the suction force in the case where the disk 21 and the yoke 23 are in contact. It has become. Even if there is a gap between the magnet 27 and the disk 21, as long as the disk 21 and the yoke 23 are in contact with each other, the decrease in the attractive force is slight, and the attractive force is stable.
  • the magnet 27 is fixed to the yoke 23 via an adhesive, and the position of the lower surface of the magnet 27 varies due to variations in the thickness of the adhesive. Further, the surface accuracy of the fired magnet 27 is poor, and the position of the lower surface of the magnet 27 varies due to this accuracy. Thus, it is difficult to create a state in which the disk 21 and the yoke 23 are in contact with each other and the disk 21 and the magnet 27 are in contact with each other due to manufacturing variations. Therefore, a slight gap is provided between the lower surface of the magnet 27 and the disk 21 in consideration of variations in the adhesive and the surface accuracy of the magnet 27 so that the disk 21 and the yoke 23 are completely in contact with each other. 21, the dimensions of the yoke 23 and the magnet 27 are set. The magnet 27 is subjected to high-precision polishing to reduce the variation. By providing a gap between the magnet 27 and the disk 21, it is not necessary to perform highly accurate polishing or the like.
  • the magnet 27 is provided so as to be positioned in the coil spring 22. Therefore, the coaxial connector 1 can be reduced in size as compared with the coaxial connector in which a magnet is provided outside the coil spring.
  • a coaxial connector is not limited to the coaxial connector 1 which concerns on the said embodiment, It can change variously within the range of the summary.
  • the yoke 23 and the magnet 27 are attached to the sleeve 30, and the disk 21 is attached to the housing 25.
  • the attachment positions of the yoke 23, the magnet 27, and the disk 21 are not limited thereto.
  • the yoke 23 and the magnet 27 may be attached to the housing 25, and the disk 21 may be attached to the sleeve 30.
  • the yoke 23 and the magnet 27 are attached to the sleeve 30, and the disk 21 is inserted into the housing 25. It is preferable to attach.
  • a magnet may be provided instead of the disk 21.
  • the coil spring 22 and the magnet 27 are provided relatively close to each other, but they may be provided separately.
  • the present invention is useful for a coaxial connector, and is particularly excellent in that a coaxial connector having excellent durability can be obtained.
