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.

First claim

What is claimed is:

1 . A coaxial connector configured on an end of a coaxial cable including a central conductor, a dielectric surrounding the central conductor, an external conductor that covers the dielectric, and an insulating sheath that clads the external conductor, the coaxial connector comprising:
a contact capable of being connected to a cylindrical mating contact, the contact including a pair of fixed terminals and a movable terminal, the terminals being erected from a tip end side of a strip-shaped metal plate and being capable of externally contacting the mating contact by three-point contact; a housing including a first connection base and a second connection base, the first connection base including an accommodation space in which one surface side is open such that the mating contact is insertable and the pair of fixed terminals and the movable terminal are disposed inside, the second connection base partially protruding from the first connection base; a conductive shell including a cylindrical portion that is open to the one surface side and is provided to surround the first connection base, and an extension portion at least including a gutter-shaped that is coupled to the cylindrical portion and is capable of accommodating the second connection base therein; and a crimp housing including a slot that is notched so as to be capable of pressing an outer periphery of the central conductor and capable of being inserted from an opening side of the accommodation space toward a predetermined portion of the second connection base, wherein the contact includes an installation surface in which a base end side of the metal plate is exposed on a predetermined surface of the second connection base, the installation surface being capable of coming into contact with the central conductor, and wherein the extension portion of the shell includes a pair of first barrels capable of pressing the crimp housing against the second connection base, and a pair of second barrels capable of crimping the external conductor.

2 . The coaxial connector according to claim 1 , wherein
the crimp housing is provided with a pair of lances disposed across straddle the slot, at one end thereof, and the second connection base portion is formed a pair of steps that can be engaged with the pair of the lances at a predetermined portion thereof.

3 . The coaxial connector according to claim 1 , wherein
the pair of fixed terminals are located at a set of vertices among vertices of a virtual equilateral triangle inscribed in the mating contact, and the movable terminal is located at the other vertex of the virtual equilateral triangle, and is disposed in a state of facing an intermediate portion of the pair of fixed terminals.

4 . The coaxial connector according to claim 1 , wherein
the contact is molded integrally with the housing, and the contact includes at least: an installation surface in which a base end of the metal plate is exposed on a predetermined surface of the second connection base, the installation surface being capable of coming into contact with the central conductor; and contact edges of the pair of fixed terminals, the contact edges being exposed to the accommodation space and capable of coming into contact with the mating contact.
