Description

Connector with multi-height mating groove structure

Technical Field

The present invention relates to a connector, and more particularly, to a connector having a multi-height fitting groove structure.

Background

With the progress of communication technology and electronic technology, electronic devices with various functions, such as: portable power devices for mobile phones to supply power continuously, mobile phones that enable people to communicate at both ends of the world, walkmans that enable people to listen to music anytime and anywhere, and personal computers (personal computers) … that assist people in dealing with various things have become indispensable tools in modern people's life and work.

In order to receive electronic signals and power from the outside, various electronic devices (e.g., smart phones, tablet computers, desktop computers, notebook computers, digital cameras …, etc.) usually have to arrange signal connectors on the body of each electronic device, generally speaking, a signal connector (connector) refers to all connecting elements and accessories thereof applied to electronic signals and power, and is a bridge for all signals, the quality of which affects the reliability of current and signal transmission and is also closely related to the operation of the electronic device.

As the application and installation location change, the connector also has a variety of different types of structures to accommodate and meet the requirements of use. For example, when the host of an electronic device (e.g., a desktop computer, a server, a car computer …, etc.) is bulky, or the installation location is complicated or hidden, most workers in the art adopt the design structure of the strip line connector to utilize the length of the strip line connector, so that another electronic product can be electrically connected to the electronic device, or the connector of the electronic device can be conveniently connected to a circuit board to transmit signals or power.

Furthermore, with the trend of increasingly thinner and smaller electronic devices, the configurations of the signal connectors have to be developed in an increasingly precise and small direction to be smoothly installed in the electronic devices, however, the structure of the signal connectors is becoming more precise and the structural strength of the signal connectors is weakened, so that the signal connectors are prone to influence the transmission performance due to unstable connection or reduce the service life of the signal connectors due to improper operation of users. However, in the conventional connector, if the user applies improper force or the plugging direction is deviated during the plugging process (especially under the blind plugging condition), the insulating body or the housing of the connector is easily deformed and damaged. Therefore, how to effectively solve the above problems is a major subject of the present invention.
