USB Type-C socket connector convenient for firm welding

Abstract

The invention discloses a USB Type-C socket connector convenient for firm welding. The USB Type-C socket connector convenient for the firm welding comprises a metallic shield shell and an inserting component; the metallic shield shell is provided with more than two pairs of welding leg sets; and the rear row of the welding leg set is higher than the front row of the welding leg set. The USB Type-C socket connector convenient for the firm welding is used for, only if the actual deviation value of the welding leg set is not greater than the preset height difference value between the rear row of the welding leg set and the front row of the welding leg set, ensuring the welding reliability of the front row of the welding leg set and the substrate. The producer only detects the rear row of the welding leg set convenient for the detection under the usual situation, and the welding firmness of the USB Type-C socket connector can be determined directly. The product reliability is improved, and the production difficulty and production cost are reduced.

Description

technical field [0001] The invention relates to an electrical connector, in particular to a USB Type C socket connector which is convenient for firm welding. Background technique [0002] USB is the abbreviation of Universal Serial Bus (Universal Serial Bus) in English, and its Chinese abbreviation is "through string", which is an external bus standard used to standardize the connection and communication between computers and external devices. The USB interface supports the plug-and-play and hot-swap functions of the device. USB was jointly proposed by Intel, Compaq, IBM, Microsoft and other companies at the end of 1994. [0003] The existing USB includes three interface types: Type A, Type B and Type C. Among them, the Type C interface has the characteristics that both front and back can be inserted to complete the pairing, and is more suitable for use in increasingly miniaturized computing devices. [0004] With the rapid development of science and technology in the ele...

AI Technical Summary

Problems solved by technology

The size of the new generation of USB Type C connectors is smaller and the distance between the solder legs is smaller. If the existing solder leg design is adopted, the design height of the solder legs of the shell is on the same plane. Due to technological reasons, the height of each solder leg may exist Errors, causing a certain soldering pin to be different from other soldering pins on the same plane, and the soldering is not reliable, which affects the reliability and stability of the USB Type C connector

More importantly, after the USB Type C receptacle connector is soldered, the soldering pins in the rear row will easily cover the soldering pins in the front row. , the manufacturer is unable to determine whether the front welding foot group needs secondary reinforcement, and the reliability of the product cannot be guaranteed
