Problems solved by technology

[0004] However, since the above operation needs to be irradiated on the board surface of the uppermost conductive terminal for a long time, it is easy to cause the board surface of the uppermost conductive terminal to be burned due to overheating, especially in the case where the number of the conductive terminals is larger. Under normal circumstances, the degree of burn is more serious, which affects the electrical conductivity and overall appearance of the terminal group

Abstract

The invention discloses a terminal group and a forming method thereof, and the terminal group comprises a lower terminal which is provided with a lower main body part and a lower contact arm extendingforwards from the lower main body part; a first upper terminal provided with a first upper main body part, a first upper convex part which protrudes downwards from the first upper main body part anda first upper contact arm which extends forwards from the first upper main body part, wherein the first upper contact arm and the lower contact arm are arranged in a vertically spaced mode, and each first upper convex part is provided with a first upper welding plane which abuts against the top surface of the lower main body part downwards and is in laser welding with the top surface; second upperterminal. The group also comprises a second upper contact arm provided with a second upper main body part, wherein a second upper convex part convexly arranged downwards from the second upper main body part, and a second upper contact arm extending forwards from the second upper main body part; the second upper contact arm and the first upper contact arm are arranged in an up-and-down spaced mode, the second upper protruding parts and the first upper protruding parts are arranged in an up-and-down staggered mode, and each second upper protruding part is provided with a second upper welding plane which downwards abuts against the top face of the first upper body part and is in laser welding with the top face of the first upper body part.

Description

【Technical field】 [0001] The invention relates to a terminal group and its forming method, in particular to a terminal group for transmitting large current and its forming method. 【Background technique】 [0002] A terminal set in the prior art is used to electrically connect a pair of joints to transmit large currents. The terminal set includes a plurality of conductive terminals in the shape of a plate, and each conductive terminal has a contact arm for contacting the butt joint. A plurality of conductive terminals are stacked together in a vertical direction, and the board surfaces of two vertically adjacent conductive terminals are in contact with each other. In order to be suitable for transmitting large currents, the number of the conductive terminals is generally three or more. [0003] When the terminal group is formed, a plurality of conductive terminals are first stacked together in the vertical direction, so that the board surfaces of the two adjacent conductive t...
