The axial direction of the first spring needle is consistent with the axial direction of the inner conductor 2, the first spring needle is fixedly connected with the inner conductor 2 to realize electric conduction, and the needle head of the first spring needle faces away from the inner conductor 2, as shown in fig. 1. In the implementation, the needle head of the first spring needle is abutted against the inner conductor access contact on the corresponding circuit board, so that the electric conduction between the inner conductor 2 and the circuit board is realized. The two ends of the inner conductor 2 of the connector of the embodiment are respectively connected with the corresponding circuit board by adopting the soft connection mode of elastic conductive structures such as spring pins, and the like, so that on one hand, the connector can be ensured to be more convenient to install and more stable to connect, and on the other hand, the inner conductor 2 can be prevented from being damaged due to too strong rigidity during assembly.
As shown in fig. 1, a preferred embodiment is schematically shown, wherein the floating member 12 is at least partially located in the lumen of the main body member 11, i.e. one end of the floating member 12 is located in the lumen of the main body member 11. A first stop structure 121 is disposed on the outer wall of the floating member 12, and the first stop structure 121 is preferably an annular protrusion structure disposed on the outer wall of the floating member 12, and the axial direction of the first stop structure is identical to the axial direction of the floating member 12, so that two stop surfaces are formed on the outer wall of the floating member 12 along the axial direction, as shown in fig. 1 and 2, a right side surface of the first stop structure 121 shown in the definition diagram is a first stop surface 1211, and a left side surface is a second stop surface 1212.

The size of the first cavity 115 matches the size of the first stop structure 121, the size of the second cavity 116 is smaller than the size of the first stop structure 121, so that when one end of the floating member 12 is installed in the lumen of the main body member 11, the first stop structure 121 can be disposed in the first cavity 115, and the third stop surface 1111 realizes axial limitation on the first stop structure 121.
The third stop structure 112 is preferably obtained by spin riveting the end of the first end 113 of the body member 11. Specifically, after the floating member 12 is mounted, the end portion of the first end 113 of the main body member 11 is screwed and riveted by a screwing and riveting process to close the end portion inwards, so that the size of the opening at the first end 113 of the main body member 11 is smaller than that of the first stop structure 121, and the part of the first end 113 that closes inwards forms the third stop structure 112, so that the first stop structure 121 is axially limited, as shown in fig. 1 and 2.

And the outer diameter of the structure surrounded by the first plurality of raised structures 1222 is greater than the inner diameter of the second chamber 116. When the floating member 12 is mounted in the main body 11, the slotted petal end of the floating member 12 is inserted from the first chamber 115 into the second chamber 116, and the first elastic claw 122 at the end of the floating member 12 is restrained and contracted inwards under the limitation of the inner wall of the second chamber 116, so that an outwards expanding force is generated, and the first protrusion structure 1222 is tightly abutted with the inner wall of the second chamber 116, so that electric conduction is realized.

When the floating member 12 receives the rightward acting force in the figure, the floating member 12 will move rightward and compress the spring, so as to realize the length adjustment of the outer conductor 1, thereby meeting the design requirements of different intervals between circuit boards, and having stronger universality. The spring can also apply axial elastic force to the floating piece 12, so that the floating piece 12 can better abut against a corresponding circuit board, and the stability of connection between the floating piece 12 and the corresponding circuit board is ensured. It is further preferable that the portion of the floating member 12 located on the right side of the first stop structure 121 is configured to have a reduced diameter, so that a larger accommodating space is formed between the floating member 12 and the main body member 11 to better accommodate the elastic member 3.
