The first support protrusions 11 and the second support protrusions 12 are used to support the inserted mating terminals to prevent the elastic arm 32 of the elastic member 3 from being excessively squeezed by the mating terminals.

[0090] like Figures 1 to 13 As shown in the illustrated embodiment, a support rib 132 extending along the first direction D1 is formed on the top surface of the terminal plate 1. The support rib 132 is located below the plurality of elastic arms 32 of the elastic member 3 and is used to support the elastic arms 32 to prevent the elastic arms 32 from being excessively deformed.

[0091] like Figures 1 to 13 As shown in the illustrated embodiment, the elastic element 3 is a one-piece stamped part.

[0092] like Figures 1 to 13 As shown, in another exemplary embodiment of this utility model, a terminal assembly is also disclosed. The terminal assembly includes a connector terminal and a cable 5. One end of the cable 5 is soldered to the top or bottom surface of the connector terminal's connecting plate 2.

[0093] like Figures 1 to 13 As shown in the illustrated embodiment, cable 5 is soldered to connecting plate 2 before connecting plate 2 is fixed to terminal plate 1. Cable 5 can be soldered to connecting plate 2 using an ultrasonic welding process. In this embodiment, since cable 5 is soldered to connecting plate 2 before connecting plate 2 is fixed to terminal plate 1, the elastic element 3 is not affected by the ultrasonic waves during the welding of cable 5.

[0094] However, this utility model is not limited to the illustrated embodiment. For example, in another exemplary embodiment of this utility model, the cable 5 can be welded to the connecting plate 2 after the connecting plate 2 is fixed to the terminal plate 1. In this case, if an ultrasonic welding process is used to weld the cable 5 to the connecting plate 2, the elastic element 3 will be affected by the ultrasonic waves and is prone to cracking. Therefore, in this case, it is not advisable to use an ultrasonic welding process to weld the cable 5 to the connecting plate 2.

[0095] like Figures 1 to 13As shown, in another exemplary embodiment of this utility model, a connector is also disclosed. The connector includes a housing and the aforementioned connector terminals or terminal assemblies. The connector terminals are inserted into the housing.
