[0023] like Figure 1-5 As shown, a double-row connector with positioning function includes a plastic body 1 and a PIN pin terminal 2. The plastic body 1 is provided with an insertion cavity 5, and the bottom surface of the insertion cavity 5 is provided with a PIN hole 6. The PIN pin terminal 2 is loaded from the insertion cavity 5 and inserted through the PIN hole 6 to be fastened. The outer wall of the plastic body 1 is provided with a positioning structure. There are a plurality of PIN pin terminals, and they are arranged in two rows. The interval between two adjacent PIN pin terminals is 4.2 mm. Therefore, of course, in order to meet other needs, other spacings can also be set. The positioning structure can be used to facilitate the assembly of the PCB board, play a positioning role, and then ensure the accuracy of welding, and also improve the stability and reliability of the overall assembly. The PIN pin terminal is inserted from the insertion cavity, and then the front end of the PIN pin terminal extends from the PIN hole. The PIN pin terminal is clamped and fastened in the PIN hole, and the PIN pin terminal is completely located inside the insertion cavity. The wire end to be connected extends into the insertion cavity and is connected to the PIN pin terminal to achieve electrical conduction.

[0024] The positioning structure is a positioning column 3, the lower end of which extends to the lower area of ​​the bottom surface of the plastic body 1. Two positioning columns are provided, and the two positioning columns are symmetrically arranged on both sides of the plastic body. The positioning column 3 is provided with a slot 4 along the axial direction.

[0027] The boss 8 and the positioning structure are arranged on different outer side walls of the plastic body and will not interfere with each other.

[0028] The positioning column 3 is integrally formed on the plastic body 1; or the positioning column is assembled on the plastic body as a separate component.

[0029] The end of the positioning column 3 has a radial convex wall 9, forming a "mushroom" shape, which can better position and fix the PCB board.
