With the gradual maturity of the development of electronic equipment, thin and light design has become a major development trend for electronic equipment to meet the needs of users. However, when the conventional standardized interface 10 is set up, it cannot be designed to be reduced due to the limitation of the internal stacking space of the whole electronic device, which makes it impossible to reduce the size of the interface 10 to realize the whole electronic device. Small size design.

In order to solve the above-mentioned problems, the present application provides a connector, which has a small volume, so as to facilitate the miniaturization and thinning design of an electronic device provided with the connector. In order to understand the connector provided by the embodiments of the present application, the specific arrangement manner of the connector will be described in detail below with reference to the accompanying drawings.
