Coaxial connector, high frequency unit, and receiver
A coaxial connector includes a cylindrical external conductor including a metal material, a first insulating member arranged in the external conductor, a second insulating member including a front surface plate in which a wire insertion hole is formed and a plurality of elastic pieces which extends from the front surface plate toward a rear surface and of which an end overlaps with a side of a front surface of the first insulating member and is movable in a direction from a front surface toward a rear surface, and a center electrode arranged in a hollow portion in the first and second insulating members and including a terminal led out from a rear surface of the first insulating member to outside and clamping pieces for clamping the wire connected to the terminal.
1. A coaxial connector comprising:
a cylindrical external conductor including a metal material;
a first insulating member arranged in the external conductor;
a second insulating member including a front surface plate in which a wire insertion hole is formed and a plurality of elastic pieces which extends from the front surface plate toward a rear surface and of which an end overlaps with a side of a front surface of the first insulating member and is movable in a direction from a front surface toward a rear surface; and
a center electrode arranged in a hollow portion in the first and second insulating members and including a terminal led out from a rear surface of the first insulating member to outside and clamping pieces for clamping the wire connected to the terminal.
2. The coaxial connector according to claim 1 , wherein
on a side of the front surface of the first insulating member, an inclined surface or a protrusion to spread ends of the elastic pieces outward is formed.
3. The coaxial connector according to claim 1 , wherein
the clamping piece of the center electrode includes a contact portion for clamping the wire, and
a cross-section of the clamping piece including the contact portion has a plate-like shape, and a cross-section of other portion of the clamping piece has an arc-like shape.
4. The coaxial connector according to claim 1 , wherein
the first insulating member has a hole for supporting the clamping piece and leading out the terminal.
5. The coaxial connector according to claim 4 , wherein
the pair of elastic pieces having an arc-like cross-section faces to each other and is planted on the front surface plate.
6. The coaxial connector according to claim 5 , wherein
a part of a facing surface of the pair of elastic pieces is thin, and a recess is formed on an outer side of the center electrode.
7. The coaxial connector according to claim 5 , wherein
portions of the facing surfaces of the pair of elastic pieces close to the front surface plate are brought closer to the clamping pieces of the center electrode.
