And the other side of the protrusion in the center axis direction
A second step surface extending in a radial direction , wherein the insulating member has an insertion hole through which the center conductor is inserted in the axial direction ;
A main body portion that is inserted into the inner surface of the protrusion, from the body portion and the first holding portion which extends to one side of the axial direction, from the main body portion extends and the second to the other side of the axial In the method of assembling a coaxial connector having a holding portion, the center conductor is formed at the center of the insulating member.
A conductor holding portion inserted into the insertion hole, and the conductor holding portion
One side portion extends from the end face of the first holding portion to the external conductor.
First contact portion extending near one side of the opening in the first contact portion
And the other side portion extends from the end face of the second holding portion to the external guide.
A second extending into the vicinity of the opening on the other side of the body
The contact portion and the portion held by the second holding portion are
The diameter gradually increases from the first contact portion to the second contact portion.
Has a tapered portion where
With a diameter smaller than the diameter of the inner wall of the conductor
The insertion hole is provided at the tip of the first holding portion.
A pair of semicircular shapes extending in the radial direction so as to close
Is formed between the closed wall portions.
Cut the holding part from the outer end face into half shape
Ri Contact write portion is formed, the insulating member from the other side the opening side of the outer conductor to the inside
And project the first holding portion forward from the projecting portion.
And holds the main body to the projection,
The outer peripheral surface of the holding portion 2 faces the inner wall surface of the outer conductor.
And one side parallel to the radial direction of the second holding portion is moved forward.
Abutting against the second step surface, and then in front of the insulating member;
By inserting the center conductor into the insertion hole,
The center conductor is located on the first contact portion side, and the
The insertion of the insulating member from the opening side on the other side of the conductor
Penetrated into the hole and penetrated into the cut portion of the closed wall portion
And insert the center conductor further to widen the closing wall.
In the direction of the outer conductor to open the closed wall portion.
Causing the first holding portion to interfere with the first step portion,
Insert the tapered portion into the second holding portion and insert
A method of assembling a coaxial connector, characterized in that the connector is vertically fixed .
