As shown in fig. 1, the present utility model discloses a connector structure comprising a housing 1, a center conductor 2 and a medium 3 between the housing 1 and the center conductor 2.

The housing 1 and the center conductor 2 are generally made of metal materials, and the medium is made of nonmetallic materials. As shown in fig. 2, the outer wall of the central conductor 2 is provided with a protruding strip 21 and a barb ring structure 22 arranged parallel to the axis thereof. There are at least two ribs 21. Preferably, the protruding strips are arranged in a plurality and uniformly arranged around the outer wall of the central conductor 2, and the protruding strips and the central conductor 2 are arranged in parallel with the axis of the protruding strips, so that the central conductor 2 and the medium can be effectively prevented from relative rotation. The barbs on the central conductor 2 are in a ring structure, so that the axial relative movement between the central conductor 2 and the medium can be effectively prevented.

The inner wall of the shell 1 is provided with a barb section structure 11. The barbs on the shell are in a segment structure, a tooth breaking structure is arranged between two adjacent segments of barbs, and after the metal shell 1 is assembled with the medium 3 made of a non-metal material, the barb segment structure 11 can not only prevent relative rotation between the shell 1 and the medium 3, but also prevent relative axial movement between the shell 1 and the medium 3. The outer wall of the shell 1 is also provided with a thread structure so as to realize threaded connection with the test piece.

Since the medium is a non-metallic material, it has a certain softness, but it must not be too soft in order to ensure the stability of the connection. Therefore, the assembling of the connector can be completed and the connection tightness requirements of all the components can be met by only arranging the convex strips 21, the barb ring structures 22 and the barb segment structures on the shell 1 and the central conductor 2.

In order to increase the reliability of preventing relative movement and rotation between the housing 1 and the medium 3, the barbed section structure 11 has at least two sections. As shown in fig. 3, there is shown an example in which the barb segment structure 11 has four segments and is uniformly disposed around the inner wall of the shell 1.

To further avoid relative movement of the housing 1, the center conductor 2, and the medium 3 during insertion and extraction, the barb segment structure 11 is oriented in the opposite direction to the barb loop structure 22, as shown in fig. 1. The direction of orientation, i.e. the direction in which the barb structure prevents movement.

When in assembly, the medium is firstly filled into the shell, and then the central conductor is filled into the medium.

The utility model discloses equipment, which is coaxial equipment, and a welding spot at the tail part of a connecting piece of the equipment is welded with a PCB through a microstrip line. Specifically, as shown in fig. 4, the apparatus includes a housing 4 having a cavity, a PCB board 5 disposed in the housing, and a connector disposed on the housing 4 and soldered to the PCB board 5 by a microstrip line, where the connector is one of the first aspect and any of the possible designs thereof. Specifically, the PCB 5 is provided with an input and output belt line, the PCB 5 is fixed in the cavity of the shell through a screw, and the central conductor of the connecting piece is plated with gold; holes for installing connecting pieces are formed in the shell 4, and the positions of the holes correspond to positions of input and output strip lines on the PCB 5.

During installation, the PCB is fixed in the cavity by the screws, then the holes of the connecting piece manned shell are screwed by 2 combined screws with elastic flat pads, the tail of the connecting piece is soldered with the PCB microstrip, and the soldering spots are full and smooth without the phenomena of pull tips and cracks.

During testing, the testing piece is installed into the connecting piece, the opening position of the central conductor of the connecting piece is opened to be in close contact with the testing piece, and the central conductor receives a pushing force during installation, but under the action of the raised strips 21, the barb ring structures 22 and the barb segment structures 11, the mutual friction force among parts of the parts is increased, the rotation preventing capability is improved, and the rotation and the forward and backward movement phenomena between the shell and the medium and between the central conductor and the medium can be prevented after the connecting piece is used repeatedly or at high and low temperatures. By adopting the structure, the reliability of the equipment is enhanced, the maintenance cost is reduced, and the service life of the product is prolonged.
