Abstract

A coaxial connector including a connector main body is formed of an upper housing and a lower housing. An outer conductor includes a circular cylinder portion surrounding the periphery of a hole of the connector main body and configured to be inserted into an outer conductor of a mating coaxial connector. A main body portion is provided on the connector main body, and a fixation portion that is extended from the main body portion so as to sandwich the connector main body along with the main body portion. A fixed terminal is anchored to the connector main body. A movable terminal includes a fixation portion anchored to the connector main body, and a plate spring that extends from the fixation portion toward the fixed terminal and overlaps with the fixation portion at tip ends of the plate spring.

First claim

The invention claimed is:

1. A coaxial connector on which is mounted a test coaxial connector that includes a probe extending in a vertical direction and a first outer conductor having a cylinder shape and surrounding a periphery of the probe, the coaxial connector comprising:
a connector main body including an upper surface and a bottom surface, and a hole formed in the connector main body through which the probe is inserted from an upper side to a lower side of the hole;
a second outer conductor including a cylinder portion surrounding a periphery of the hole and configured to be inserted into the first outer conductor, an outer conductor main portion provided on the upper surface, and an outer conductor fixation portion which is extended from the outer conductor main portion to the bottom surface so as to sandwich the connector main body along with the outer conductor main portion;
a fixed terminal anchored to the connector main body; and a movable terminal including a movable terminal fixation portion anchored to the connector main body, and a plate spring extending from the movable terminal fixation portion toward the fixed terminal, making contact with the fixed terminal, and overlapping with the outer conductor fixation portion at a tip end of the plate spring when viewed from bottom,
wherein the plate spring is displaced downward by the probe so as to be separated from the fixed terminal.

2. The coaxial connector according to claim 1 , wherein the plate spring makes contact with the connector main body at the tip end of the plate spring.

3. The coaxial connector according to claim 1 , wherein the fixed terminal includes:
a fixed terminal fixation portion anchored to the connector main body; and
a contact portion that is formed by being bent upward relative to the fixed terminal fixation portion, and that makes contact with the plate spring at a part where the contact portion is bent downward.

4. The coaxial connector according to claim 1 , wherein the plate spring includes two branches that are formed branching to two sections at the tip end side of the plate spring,
the fixed terminal is located between the two branches, and
at least no less than two outer conductor fixation portions are provided so as to overlap with tip ends of the two branches.

5. The coaxial connector according to claim 4 , wherein there are provided two contact portions so as to correspond to the two branches, respectively.

6. The coaxial connector according to claim 1 , wherein the plate spring is curved so as to project upward.
