Claims (7)

[Claims] 1. A coaxial connector body having a connector connecting portion provided at one end in the axial direction and a connector fixing portion provided at the other end side of the connector connecting portion, and a connector fixing portion of the coaxial connector body is inserted therethrough. A mounting plate having a mounting hole, and a stopper for engaging the connector fixing portion inserted in the mounting hole of the mounting plate from a direction intersecting the axial direction to lock the coaxial connector body to the mounting plate. A coaxial connector characterized in that 2. The coaxial connector main body extends along the peripheral surface of the connector fixing portion and the flange portion protruding from the peripheral surface between the connector connecting portion and the connector fixing portion and abutting against the peripheral edge portion of the mounting hole of the mounting plate. The stopper has a locking groove provided, and the stopper engages with the locking groove of the connector fixing portion inserted into the mounting hole of the mounting plate from a direction intersecting the axial direction to clamp the connector fixing portion on both sides. The holding portion, and a holding portion that presses the locking portion that abuts the mounting plate and that engages with the locking groove of the connector fixing portion in the insertion direction of the connector fixing portion. The described coaxial connector. 3. The stopper holding portion includes a base-side holding portion connected to the base ends of the locking portions on both sides, and tip ends on both sides arranged along the locking portions on both sides from the base-side holding portion. A holding portion is provided, and a cutout portion that allows engagement of the locking portion with the locking groove of the connector fixing portion is provided at the front end portions of the holding portions on both sides facing the mounting plates. Claim 2
The described coaxial connector. 4. The mounting plate has a mounting plate portion provided with mounting holes, and side plate portions on both sides bent from both sides of the mounting plate portion in a direction corresponding to the insertion direction of the connector fixing portion. 4. The abutting portions that are inserted between the side plate portions on both sides of the mounting plate and that abut against and press the side plate portions on both sides are provided on the tip side holding portions on both sides of the mounting plate. Coaxial connector. 5. The stoppers on both sides of the stopper are provided with restricting portions that project laterally from the engaging portions on both sides and can come into contact with each other, respectively. Coaxial connector. 6. The engaging portions on both sides of the stopper are provided with engaging portions that engage with the front end side holding portions on both sides and press in the inserting direction of the connector fixing portion. A coaxial connector according to any one of 1 to 5. 7. The joint portion, which is joined to the outer surface of the connector fixing portion, is cut and raised in the insertion direction of the connector fixing portion at the edge portion of the mounting hole of the mounting plate.
7. The coaxial connector according to any one of 1 to 6.
