[0036] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0037] See also Figure 1 and Figure 2 The embodiment of the present application discloses a small board-end connector that is easy to assemble, including a connector 10, a power supply 20 and a conductor assembly 30. The two ends of the connector 10 are provided with a first through slot 11 and a second through slot 12 (see Figure 3 ), the power supply component 20 is fixed on the connecting component 10 through the first through slot 11, and the conductor component 30 is fixed on the connecting component 10 through the second through slot 12, so as to facilitate the assembly of the board-end connector and improve production efficiency.

[0038] There are two power supply components 20 corresponding to the first through-slots 11, one end of the power supply component 20 passes through the first through-slot 11, and the other end passes through the first through-slot 11 and is bent to play a limiting role. The conductor assembly 30 is arranged at the other end of the connector 10, and includes a shell conductor 31, a support member 32 and a terminal 33 nested in sequence. One end of the terminal 33 (also known as the signal terminal 33) passes through the second through-slot 12 and is located in the support member 32, and the other end passes through the second through-slot 12 and is bent, so that the conductor assembly 30 can be fixed on the connector 10. It is explained here that in this embodiment, the support member 32 can be integrally connected to the connector 10, such as Figure 2 shown.

[0039] See also Figure 2 In order to make the power supply component 20 more firmly fixed on the connecting member 10, a third protrusion 21 equivalent to a stop member is provided on the outer side of the power supply component 20, for example, four protrusions are provided, which are used to abut and engage in the first through groove 11 to be fixed on the connecting member 10, so as to prevent the power supply component 20 from slipping out of the first through groove 11 during use.

[0040] See also Figure 2 and Figure 3 In order to prevent the shell conductor 31 from being nested on the support member 32 and rotating, a second protrusion 312 that abuts against the connector 10 is also provided on the side of the shell conductor 31 close to the connector 10, and the second protrusion 312 is located in the connector 10 to limit the shell conductor 31.
