Detailed Description

The present invention will be described below based on examples, but the present invention is not limited to only these examples. In the following detailed description of the present invention, certain specific details are set forth in detail. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. Well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present invention.

Further, those of ordinary skill in the art will appreciate that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.

Unless the context clearly requires otherwise, throughout this application, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, what is meant is "including, but not limited to".

In the description of the embodiments of the present invention, it should be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

Unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," and the like are intended to be inclusive and mean that, for example, they may be fixedly connected or detachably connected or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

When an element or layer is referred to as being "on," "engaged to," "connected to" or "coupled to" another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being "directly on," "directly engaged to," "directly connected to" or "directly coupled to" another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a similar manner. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Spatially relative terms, such as "inner," "outer," "below," "lower," "above," "upper," and the like, are used herein for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the example term "below" can encompass both an orientation of above and below. The device may be otherwise oriented and the spatially relative descriptors used herein interpreted accordingly.

Kneeling PIN means that the terminals are permanently deformed, resulting in poor contact between the terminals.

The USB interface has three interfaces with different appearances, namely Type-A, Type-B and Type-C. Type-A is the most extensive interface standard among computer, the electronic accessories, and mouse, USB flash disk, data line are all this interface mostly, and the volume is also the biggest. The iron shell elastic sheet of the Type-A connector is of an elastic point Type, and the head of the elastic sheet exceeds the surface of the outer iron shell after the male connector is inserted into the structure, and the kneeling PIN phenomenon is easily caused. The Type-A connector is easy to damage and short in service life, and user experience is poor. In a comparative example, the terminal and the insulator are separated, the terminal is combined in a mode of inserting the terminal into the insulator, the material belts of the terminal are respectively cut off after the terminal and the terminal are combined, the rubber core and the terminal are placed in the shell, the production process is complicated, and the yield of products in the production process cannot be guaranteed.

In view of this, the present disclosure provides a connector, which can prevent the connector from being damaged easily during the use process, and can improve the production efficiency and yield of the connector.

The embodiment of the present application is described with respect to a Type-a connector, but in other implementations, the connector structure of the present application may be used for Type-B and Type-C connectors.
