Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and in particular to a D-SUB connector that is easy to solder and its male and female connectors. Background Technology

[0002] Electronic connectors, also known as circuit connectors or electrical connectors, are conductor devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to the other. The D-SUB connector is one of many types of electrical connectors.

[0003] Traditional D-SUB connectors consist of an insulating body, several conductive terminals housed within the insulating body, and a metal shell covering the insulating body. The terminals generally include a contact portion at the front end, a cylindrical portion in the middle, and a soldering portion at the rear end. Before use, solder wire needs to be melted into molten solder and soldered between the soldering portion of the terminal and the wire. During this process, it is necessary to prevent the molten solder from flowing into the contact portion through the cylindrical portion; otherwise, the processed terminal will be unusable. Traditional terminals will have the cylindrical portion in the middle hammered flat. This method requires processing on tiny terminals, making the process difficult to control. Even slight deviations can easily cause the terminal to be scrapped, which is not conducive to cost control. Utility Model Content

[0004] The purpose of this utility model is to provide a D-SUB connector and its male and female connectors that are easy to solder. The terminal slots of the male and female connectors penetrate the rear end surface of the insulating body to form a number of concave soldering grooves for accommodating the soldering part of the terminal. A stop part is provided on the insulating body corresponding to the end position of the soldering groove. When the terminal is placed in the insulating body, the stop part limits the cylindrical part and blocks the through hole. It is easy to process, prevents the backflow of solder during soldering, and prevents the glue from being washed away during injection molding.
