Description

Technical Field

[0001] This utility model relates to a connector. Background Technology

[0002] In the prior art, connectors typically include a housing and upper and lower rows of terminals disposed within the housing. The upper and lower rows of terminals each have a connecting portion extending from the rear side of the housing. The connecting portion of the upper row of terminals includes a first horizontal arm extending rearward along the longitudinal direction of the housing from the rear side, a first vertical arm connected to the rear end of the first horizontal arm and extending downward along the height direction of the housing, and a first soldering pin connected to the lower end of the first vertical arm and extending rearward along the longitudinal direction of the housing. The connecting portion of the lower row of terminals includes a second vertical arm extending downward along the height direction of the housing and a second soldering pin connected to the lower end of the second vertical arm and extending rearward along the longitudinal direction of the housing. Because the upper row of terminals has a relatively long first horizontal arm and a relatively long first vertical arm, it is difficult to accurately position the connecting portion of the upper row of terminals, thus failing to guarantee that the first soldering pins of the upper row of terminals are accurately positioned in the same plane. Due to the poor coplanarity of the first soldering pins of the upper row of terminals, it is difficult to reliably solder all the first soldering pins of the upper row of terminals onto the circuit board using surface mount technology.
