[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-4 , a height-adjustable board-to-board radio frequency coaxial connector, comprising:

[0027] The housing 1 has a sliding sleeve at one end thereof provided with a floating head 4;

[0028] A fixed insulator 2, which is fixed to one side of the inner cavity of the housing 1, and a fixed socket 3 is fixed at the axial center of the fixed insulator 2;

[0029] A floating insulator 5, which is fixed inside the floating head 4, and a movable socket 6 is fixed at the axial center of the floating insulator 5;

[0030] Spring 7, spring 7 is sleeved on the outside of floating head 4.

[0031] A mounting groove 8 is provided inside the housing 1 , and the spring 7 is mounted in the mounting groove 8 .

[0032] One end of the spring 7 abuts against the protrusion of the outer wall of the floating head 4 , and the other end of the spring 7 abuts against the side wall of the installation groove 8 .

[0033] A pin 9 is fixed to one end of the movable socket 6 located in the housing 1 , and the pin 9 is plugged into one end of the fixed socket 3 .

[0034] The pin 9 is slidably connected to the fixed socket 3 .

[0035] The floating head 4 is slidably sleeved outside the fixed insulator 2 .

[0036] In this embodiment, the board-to-board RF coaxial connector is based on the SMP series RF coaxial connector, which can be divided into a fixed part and a floating part. The fixed part is composed of a shell 1, a fixed insulator 2 and a fixed socket 3. This part is not adjustable and remains in a fixed state. The floating part includes a floating head 4, a floating insulator 5 and a movable socket 6, which can move as a whole. The fixed part and the floating part are connected by a spring 7 to achieve a telescopic effect. At the same time, the spring 7 is in a slightly compressed state in the initial state, and the floating head 4 abuts against one end of the shell 1. At this time, the length of the board-to-board RF coaxial connector is the longest. During operation, the floating head 4 is forced to compress the spring 7, and the floating head 4 moves toward the inside of the shell 1 to achieve the length adjustment of the board-to-board RF coaxial connector.
