Description

Technical Field

[0001] Cross - reference to Related Applications This application claims the benefit of Chinese Patent Application No. CN202423135459.0, filed with the China National Intellectual Property Administration on December 18, 2024, the entire disclosure of which is incorporated herein by reference.

[0002] The present invention relates to a connector.

Background Art

[0003] In the prior art, a connector typically includes a housing, an upper row of terminals disposed within the housing, and a lower row of terminals. Each of the upper and lower terminals has a connection portion extending from the rear surface of the housing. The connection portion of the upper terminal includes a first horizontal arm extending rearward from the rear surface of the housing along the longitudinal direction of the housing, a first vertical arm connected to the rear end of the first horizontal arm and extending rearward along the height direction of the housing, and a first welding pin connected to the lower end of the first vertical arm and extending rearward along the longitudinal direction of the housing. The connection portion of the lower terminal includes a second vertical arm extending downward along the height direction of the housing and a second welding pin connected to the lower end of the second vertical arm and extending rearward along the longitudinal direction of the housing. Since the first horizontal arm of the upper terminal is longer and the first vertical arm of the upper terminal is longer, it is difficult to accurately arrange the connection portion of the upper terminal. Therefore, it is impossible to accurately arrange the first welding pins of the upper row of terminals in the same plane. Due to the poor coplanarity of the first welding pins of the upper row of terminals, it is difficult to reliably solder all the first welding pins of the upper row of terminals to the circuit board using surface mounting.
