  • Patent number: 11777263
    Abstract: The present invention provides a coaxial connector capable of reducing harness processing steps. A coaxial connector includes a contact by three-point contact, a housing including a first and a second connection base, and a shell including a cylindrical portion accommodating the first connection base and an extension portion accommodating the second connection base. The central conductor of a cable is placed on an installation surface of a contact located in a predetermined part of a housing, and a crimp housing with a slot cut out to allow pressure on the periphery of the center conductor is used. The crimp housing is held in the housing and enclosed and tightened by a pair of crimp barrels (the first barrel) provided in the shell. This allows the central conductor to be securely crimped to the installation surface of the contact.

  • Patent number: 11626701
    Abstract: The present invention provides a coaxial connector that realizes a high frequency signal flowing through a contact in a high frequency band. A coaxial connector includes a three-point contact, a housing including a first and a second connection base, and a shell including a cylindrical portion accommodating the first connection base and an extension portion covering one opening of the cylindrical portion with a bottom plate piece and accommodating the second connection base. The bottom plate piece includes an inclined surface having a higher side on the base end portion of the metal plate and a lower side on the tip end side of the metal plate. The distance between the metal plate of the contact and the bottom surface of the shell which are isolated by an insulating material of the housing is configured to become identical between the tip end side and the base end side of the contact.

  • Patent number: 11566315
    Abstract: Provided is a hot-dip plating method that achieves good plating wettability between a metal material and a hot-dip plating bath and that makes it possible to reduce the amount of consumed energy as compared to conventional techniques. In a plating step included in the hot-dip plating method, vibration is applied to a hot-dip plating bath such that the ratio of the average sound pressure level (excluding noise) over ranges each lying between sound pressure peaks at harmonic frequencies of a fundamental frequency to the average sound pressure level (excluding noise) over the measured frequency range in an acoustic spectrum is greater than 0.2.

  • Patent number: 8921721
    Abstract: A switch device includes a lid arranged between a tactile switch, which is arranged on a substrate, and an operation button, which is coupled to a retainer so that the operation button can be pushed. The lid includes an opening at a location corresponding to the tactile switch. A lower surface of the elastic member is coupled to a surface of the lid. The operation button, when pushed, activates the tactile switch with an elastic member. The operation body, when released from the pushed state, deactivates the tactile switch as a reaction force of the elastic member returns the operation button to an initial position. The switch device includes a projection that supports the operation button. The projection is formed on an upper surface of the elastic member at a location corresponding to the surface of the lid.
