Description

[Technical Field]

[0001] This utility model relates to the field of electronic product connector technology, and in particular to a durable connector with a reasonable structural design that can significantly improve thermal conductivity. [Background Technology]

[0002] With the continuous development and progress of technology, especially the rapid development of the electronics industry, various electrical components are becoming increasingly standardized and regulated to better meet consumer needs and improve user experience. USB Type-C is a brand-new form of USB interface. It emerged with the latest USB 3.1 standard and was developed by the USB standardization organization to solve the long-standing problems of inconsistent physical interface specifications and unidirectional power transmission in USB interfaces. It integrates charging, display, and data transmission functions, and is fast, small in size, and reversible, thus showing a trend of being widely used in electronic products.

[0003] The existing Type-C connector structure has been greatly improved in terms of overall construction and smoothness of insertion and removal. For example, the design of the internal pins has been improved, which has improved the uniformity of force during insertion and removal. However, there are still some shortcomings. For example, when electronic products are connected for a long time while charging, the temperature of the connection part increases, which can easily accelerate the aging of the connector's plastic parts. Abnormalities in the structure of the plastic parts will directly affect the reliability of insertion and removal.

[0004] For example, utility model patent application number 202122036447.2, entitled "A Type-C Connector for Easy Fixation," specifically discloses a Type-C connector for easy fixation, including a shell, a plug, a base, and a fixing component. The plug is fitted onto one end of the base, the shell is fitted onto the outer end of the plug, and the fixing component is installed on the outer end of the shell. Support blocks are provided at both ends of the front of the plug, the plug has several terminals, a slot is provided at the front end of the plug, and a locking block is provided on the support block. The support block is detachably connected to the plug. The shell has a snap-fit, and the base has a snap-fit ​​that cooperates with the snap-fit. Limiting grooves are provided at both ends of the plug. The fixing component includes a top cover and a bottom shell. The top cover is installed on the top of the bottom shell, the shell has a through groove, and the top cover has a protrusion. When the support blocks are inserted into both ends of the plug, they can provide internal support for the Type-C male connector. The protrusion on the top cover can externally fix the Type-C male connector after it is inserted, thus making the Type-C connector more secure and less prone to loosening.

[0005] The technical features disclosed in the above-mentioned prior art documents are conventional connector structural features, and therefore the problems described above exist. Based on this, further improvements and enhancements are needed in the specific structural parts. [Utility Model Content]
