The first casing 41 includes a main body portion 410 for accommodating the first connector 10, a buckle portion 411 connected to the main body portion 410, and a raised portion 412 corresponding to the elastic piece 130 on the first metal casing 13. The main body portion 410 is further held by laser welding with the first metal case 13. The buckling portion 411 includes a pair of extension portions 4110 extending from the main body portion 410 and a groove 4111 formed between the extension portion 4110 and the main body portion 410. The raised portion 412 provides a deformation space when the elastic piece 130 is mated with the first electrical connector. The second casing 42 includes a mounting portion 420 mounted to the buckling portion 411 and a holding portion 421 connected to the mounting portion 420 and mounted on the second connection head 20. The mounting portion 420 has a sheet structure and is received in the card slot 4111. The mounting portion 420 and the pair of extension portions 4110 are further held by laser welding. The holding portion 421 is sleeved and mounted on the second metal casing 23. The holding portion 421 has a ring structure with a closed periphery, and the holding portion 421 and the second metal shell 23 are further held by laser welding. The metal shell 40 cooperates with the first metal shell 13 and the second metal shell 23 to seamlessly cover the adapter 100 after mating with the first connector 10 and the second connector 20. Therefore, the shielding performance of the adapter 100 is better, and high-speed signals can be transmitted. The adapter 100 further includes an inner film 60 overmolded on the outside of the second casing 42.

The electrical connection between the first connector 10 and the circuit board 50 is different from the electrical connection between the second connector 20 and the circuit board 50. In this embodiment, the circuit board 50 includes a first portion 51 mated with the first connector 10 and a second portion 52 mated with the second connector 20. The width of the second portion 52 is smaller than the width of the first portion 51. The first conductive terminal 12 of the first connector 10 is mechanically and electrically connected to the first portion 51 by means of through-hole welding. The second portion 52 is sandwiched between two rows of the second conductive terminals 22 of the second connection head 20 and is mechanically and electrically connected by surface welding.

The adapter 100 of the present invention mechanically connects the first connector 10 and the second connector 20 together through a metal shell 40, and has a better shielding performance and can transmit high-speed signals.
