This kind of single-row pin connector has a flat top surface of the plastic body and a concave bottom surface of the plastic body. When the plastic body is injection molded, the shrinkage of the top surface and the bottom surface is often inconsistent, resulting in excessive warping of the finished plastic body. False welding or virtual welding occurs when the single-row pin-row connector is welded to the holes of the PCB board, which affects the electrical connection performance.

Utility model content:

The purpose of this utility model is to provide an anti-warping single-row pin connector for the deficiencies of the prior art. The plastic body of this connector has relatively consistent shrinkage of the top surface and bottom surface during injection molding, and the plastic body of the finished product has the same shrinkage. The warpage is small, avoiding false welding or false welding during welding, improving welding quality and ensuring electrical connection performance.

In order to achieve the above object, the utility model is realized through the following technical solutions: an anti-warping single row pin row connector, which includes a plastic body and a number of pin rows, and several row pins are arranged in a single row on the plastic body, and the plastic body The bottom surface of the plastic body is concave, and the top surface of the plastic body is provided with several top grooves.

The plurality of top grooves are respectively opened between each row of pins.

The plastic body is located at the position of the top groove and has an oblong hole penetrating through the plastic body.

The front and rear sides of the plastic body are provided with several side grooves.

The plurality of side grooves are set between the pin rows respectively, and each side groove is connected with the top groove at the corresponding position to form an integrated groove.

The distance ZH between the centerlines of adjacent needle rows is 2.54±0.10mm.

The height H of the plastic body is 2.50±0.15mm.

The width W of the plastic body is 2.50±0.15mm.

The pin header is a straight pin header.

The beneficial effects of the utility model are as follows: the anti-warping single-row needle row connector described in the utility model has several top grooves on the top surface of the plastic body, and the plastic body with this structure can balance the gap between the top surface and the bottom surface. Structural differences can reduce the shrinkage difference when the plastic body is formed, thereby reducing the warping phenomenon of the finished plastic body. Therefore, the utility model has a small warpage of the finished plastic body, which avoids false welding or false welding during welding, and improves welding performance. Quality, the advantage of ensuring electrical connection performance.
