[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0025] In the embodiments of the present application, the definition of direction is for the posture shown in the drawings. In other postures, the definition of direction changes with the change of the posture, which is not limited herein.

[0026] As Figures 1-2As shown, a board end connector includes: an outer conductor 20, a center conductor 40 passing through the outer conductor 20, an insulator 30 fixed between the outer conductor 20 and the center conductor 40, and a shell 10 connected to the outer conductor 20 in a plug-in manner. The overall insulator 30 and the center conductor 40 are L-shaped, and of course can also be linear according to actual needs. The embodiment innovatively provides at least one recessed slot on the connecting surface 2014 of the outer conductor 20. The abutting surface 100 of the shell 10 is provided with a clamping strip 102 extending in the x direction. The clamping strip 102 is inserted into the slot for realizing the tight connection between the shell 10 and the outer conductor 20. The effective structural space on the outer conductor 20 and the shell 10 is used for long-distance strong interference. After the outer conductor 20 is assembled with the shell 10 by riveting, the long-distance strong interference stably fixes the shell 10, which can prevent the connector from loosening or even falling off in strong vibration, thereby ensuring the effectiveness and stability of the signal transmission of the connector. Of course, in order to realize the stable connection between the outer conductor 20 and the shell 10, the clamping strip can also be designed to extend outward on the outer conductor 20, and the slot can be designed to be recessed on the shell 10. The specific design can be made according to the actual situation, which is not limited here.

[0027] As shown in Figure 2 and Figure 7 , the outer conductor 20 includes a main body part 201 and a plug 202. The plug 202 extends in the -x direction. The end surface of the main body part 201 around the plug 202 forms the above-mentioned connecting surface 2014. The slot is provided on the connecting surface 2014. The base part 203 is further provided between the main body part 201 and the plug 202. The upper end surface and / or the lower end surface of the base part 203 is provided with a clamping rib 2030 extending in the y direction. The end of the upper end surface can also be provided with a protrusion 2031, which are all used to strengthen the clamping connection with the shell 10.

[0028] As shown in Figures 5-6 , the slot includes a first slot 2010 provided on the left and right sides of the plug 202. The first slot 2010 includes an upper wall and a lower wall opposite to each other, and a left side wall and a right side wall opposite to each other. The shell 10 includes a hollow accommodating cavity 101 and an abutting surface 100 provided at the x direction end of the accommodating cavity 101. The left and right sides (i.e. the y direction) of the abutting surface 100 are provided with clamping strips 102. The clamping strips 102 are connected to the first slot 2010 in a plug-in manner. The slot further includes a second slot 2013 provided on the lower side (i.e. the -z direction) of the plug. The abutting surface 100 of the accommodating cavity 101 in the -z direction is provided with a positioning pin 103. The positioning pin 103 is connected to the second slot 2013 in a plug-in manner. The positioning pin 103 is used to strengthen the fixed connection between the positioning pin 103 and the second slot 2013. The overall connection is shown in Figure 3 and Figure 4 .

[0029] Continuing to refer toFigures 5-7 The first guiding rib 2012 extends along the x direction on the top wall and the bottom wall of the first slot 2010, and at least one pair of second guiding ribs 2011 extend along the x direction on the left side wall and the right side wall. The guiding surface 20110 with a slope is arranged on the first guiding rib 2012 and / or the second guiding rib 2011. The side wall of the positioning pin 103 is provided with at least one convex rib 1030 with a slope 10300. A certain slope is arranged on the guiding rib, the convex rib 1030 or the clamping rib 2030, so as to realize faster and more stable matching connection between the outer conductor 20 and the shell 10.

[0030] In general, the long-distance interference structure is arranged at three different positions on the connecting surface 2014 of the outer conductor 20. After the outer conductor 20 is assembled with the shell 10 through riveting and pressing, the long-distance interference structure at the three positions stably fixes the shell 10, thereby preventing the shell 10 from loosening or even falling off.
