Description

Technical Field

[0001] This utility model relates to a connector terminal, including a terminal assembly of the connector terminal and a connector including the terminal assembly. Background Technology

[0002] In the prior art, connector terminals typically include a terminal block and contacts mounted on the terminal block. The contacts have a row of resilient arms for electrical contact with mating terminals to electrically connect the mating terminals and the connector terminals. In the prior art, the contacts have a pair of strip-shaped portions, with each end of the row of resilient arms connected to one of the strip-shaped portions. One strip-shaped portion of the contact is fixed to the top surface of the terminal block, while the other strip-shaped portion is slidably supported on the top surface of the terminal block, allowing it to move on the top surface of the terminal block when the resilient arms are deformed under pressure. In the prior art, the terminal block is typically welded to the cable using an ultrasonic welding process. During ultrasonic welding, because the other strip-shaped portion of the contact is not fixed, high-frequency vibration occurs in the contact, which can easily cause cracking of the other strip-shaped portion.
