[0027] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein. However, where appropriate, such techniques, methods, and apparatus should be considered as being part of the specification.

[0028] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0029] As shown in the drawings, Figures 1-4 A detachable board end connector includes a shielding shell 20 made of metal material, a terminal assembly 10 installed inside the shielding shell 20, and a sheath 30 arranged around the outside of part of the shielding shell 20. The outside of one of the shielding shell 20 and the sheath 30 is detachably provided with a clamping sleeve 40. One end of the clamping sleeve 40 facing the other is extended to form at least one clamping arm 401. The other of the shielding shell 20 and the sheath 30 is provided with a first clamping groove 301 for accommodating the clamping arm 401 and clamping with the clamping arm 401. The clamping arm 401 is protrudingly provided with a first protrusion 402 clamping with the first clamping groove 301. The board end connector of the present application realizes detachable connection between the sheath 30 and the shielding shell 20 through the clamping sleeve 40 when assembled, so that the installation and disassembly of the board end connector can be facilitated. At the same time, through the setting of the clamping sleeve 40, the operator can manually assemble and combine the shielding shell 20 and the sheath 30, saving the pressing jig process. In addition, the design of the sheath 30 can be simplified, the overall installation is convenient and the feedback is good, the sheath 30 can be repeatedly disassembled without damage, and the assembly efficiency and reliability are significantly improved.

[0030] In an embodiment, as Figure 1 and Figure 2As shown, the outer wall of the shielding shell 20 is provided with at least one second protrusion 201 in the circumferential direction, and the clamping sleeve 40 is provided with a second clamping groove 403 matched with the second protrusion 201, so that the detachable cooperation between the shielding shell 20 and the clamping sleeve 40 can be realized.

[0031] As shown in Figure 3 and Figure 4 Further, the first protrusion 402 and the second protrusion 201 both have an inclined surface 202 and a vertical surface 203, and the inclined surface 202 of both is arranged on the side facing the sheath 30. Specifically, during assembly, the clamping sleeve 40 is first assembled from the side of the second protrusion 201 with the inclined surface 202. The inclined surface 202 serves to guide the second clamping groove 403 to smoothly enter the second protrusion 201. After the clamping action is completed, the vertical surface 203 is used to lock the clamping sleeve 40 and the shielding shell 20. Then, the first clamping groove 301 on the sheath 30 is aligned with the clamping arm 401 arranged on the clamping sleeve 40, and the clamping arm 401 is clamped into the first clamping groove 301, so that the assembly of the board end connector of the utility model can be realized. Similarly, the inclined surface 202 and the vertical surface 203 arranged on the first protrusion 402 also serve the purposes of guidance and locking, respectively.

[0032] In an embodiment, as shown in Figure 1 and Figure 2 The clamping sleeve 40 is in a U-shaped structure, and the U-shaped structure is arranged on the outer side of the shielding shell 20. In order to achieve the best use effect, one clamping arm 401 is arranged on each of the three surfaces of the U-shaped structure in the embodiment. Correspondingly, the sheath 30 is provided with a first clamping groove 301 on each of the three surfaces. After the clamping arm 401 is clamped into the first clamping groove 301, there is a gap between the clamping arm 401 and the groove bottom of the first clamping groove 301. By pressing the first protrusion 402, the clamping arm 401 and the first clamping groove 301 can be separated. In addition, considering the convenience and aesthetics of molding, the clamping arm 401 is arranged on the outside of the second clamping groove 403.

[0033] In an embodiment, as shown in Figure 2 The end of the sheath 30 facing the shielding shell 20 is provided with a partition plate 302, and the partition plate 302 is provided with a through hole 303 for the terminal assembly 10 to pass through. The through hole 303 and the terminal assembly 10 are in clearance fit. After the plug-in end of the terminal assembly 10 passes through the through hole 303, it protrudes to the inside of the sheath 30. Since the through hole 303 and the terminal assembly 10 are in clearance fit, and the terminal assembly 10 and the circuit board are in soldered connection, the sheath 30 can be supported, preventing the sheath 30 from being deviated in the axial direction and falling off under lateral force, and further affecting the plug-in of the board end connector and the counter connector. Further, the entrance 304 of the first clamping groove is arranged on the partition plate 302, and the entrance 304 of the first clamping groove is opposite to the clamping arm 401, so as to facilitate the plug-in of the sheath 30 and the clamping sleeve 40.
