This creation relates to an electrical connector structure, and more particularly to an electrical connector structure that enables the insulation body and shield housing to be positioned more reliably.
Press, in order to make the external hard disk box have a more convenient transmission method, so the advent of IEEE1394 and USB makes the external hard disk box more convenient for storing and exchanging data. As the hard disk interface gradually shifts to the SATA generation, the external The hard disk box supports SATA capability, and also has an external standard connector design (eSATA) to make it more convenient when connected externally, and the transmission speed of eSATA is six times faster than USB2.0 and IEEE1394, which not only provides unparalleled performance, and Cost-effective and easy to integrate. This innovative interface will provide reliable PC external expansion, so that external storage can also take advantage of SATA performance and functionality without relying on USB or 1394 interfaces.
The conventional SATA connector usually has an insulating body, a plurality of conductive terminals embedded in the insulating body, and a shielding case. The front and rear ends of the two sides of the case are usually provided with downwardly extending soldering feet. The soldering pins are used to be inserted into the preset jacks on the circuit board, so that the SATA connector can be placed on the circuit board, and the soldering pins are fixed on the circuit board by soldering to position the connector; however, because When the soldering feet are placed in the jack, there is no other holding effect. Therefore, shaking or displacement is easy to occur during soldering. This not only easily results in poor soldering of the electrical connector itself and affects the transmission performance. It will also affect the soldering effect of other components on the circuit board, resulting in an increase in the overall defect rate.
Therefore, how to solve the above problems and shortcomings is the direction that related manufacturers in this industry are eager to study and improve.
Therefore, in view of the above-mentioned problems and deficiencies, the creators collected relevant information, evaluated and considered from various parties, and based on years of experience accumulated in this industry, through continuous trial and error, they began to design this type of electrical connector structure. The birth of a new patent.
The purpose of this creation is to provide an electrical connector structure. With the improvement of this creation, the electrical connector is positioned more firmly on the circuit board to avoid the phenomenon of offset and skew.
The purpose of this creation is to provide an electrical connector structure. With the improvement of this creation, the soldering feet of the shield shell will not cause welding instability due to shaking when welding.
In order to achieve the above-mentioned purpose, the present invention provides an electrical connector structure that can be used to be fixed on a circuit board. The electrical connector structure is composed of an insulating body, at least one conductive terminal group, and a shield case. The conductive terminal group The shielding shell is embedded in the insulation body, and the shielding shell is covered on the outside of the insulating body. Among them, two sides of the shielding shell are oppositely provided with a plurality of downwardly extending welding feet, and the welding feet are provided with convex protrusions. The fixed part is made to pass the soldering pin through a preset perforation on the circuit board, and the fixed part is abutted against the bottom of the perforation, so that the insulating body can be stably positioned on the circuit board to avoid the electrical connector. Looseness and displacement.
