The second side edge of the first guide groove 201 is engaged in the third dovetail groove 30111a, and the second side edge of the second guide groove 202 is engaged in the third dovetail groove 30111a.

[0050] Specifically, the first guide groove 201 and the second guide groove 202 are arranged in the same direction. When the connector 20 is to be assembled with the side socket 30, it is only necessary to simultaneously embed the second side edges of the first guide groove 201 and the second guide groove 202 into the second groove 30111 to complete the assembly of the connector 20 with the side socket 30.

[0049] In some embodiments, as shown in FIGs. 4, 5 and 7, the second groove 30111 includes a third dovetail groove 30111a and a fourth dovetail groove 30111b. The second side edge of the first guide groove 201 is engaged in the third dovetail groove 30111a, and the second side edge of the second guide groove 202 is engaged in the third dovetail groove 30111a.

[0050] Specifically, the first guide groove 201 and the second guide groove 202 are arranged in the same direction. When the connector 20 is to be assembled with the side socket 30, it is only necessary to simultaneously embed the second side edges of the first guide groove 201 and the second guide groove 202 into the second groove 30111 to complete the assembly of the connector 20 with the side socket 30. As a result, an integrated structure is formed.
