Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

Please refer to fig. 1-3. It should be understood that in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship which the products of the present invention are usually placed in when used, which is only for the convenience of describing the present invention and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The terms "horizontal", "vertical", "overhang" and the like do not imply that the components are required to be absolutely horizontal or overhang, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present invention, it should be further noted that, unless otherwise specifically stated or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may include, for example, a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, and a communication between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example (b):

as shown in fig. 1-3, an audio connector according to the present invention includes a plastic housing 1. The front end of the plastic shell 1 is provided with a jack 11 for inserting an earphone plug, and the tail end of the plastic shell 1 is provided with a slot (not shown) for inserting two sets of terminal 2 components. The two sets of terminal assemblies 2 are used for being plugged with the earphone plug.

The terminal assembly 2 includes a stationary terminal 21 and a moving terminal 22, the moving terminal 22 is disposed outside the stationary terminal 21, and the moving terminal 22 includes a fixing portion 221, an elastic portion 222, and a contact portion 223. The fixed part 221 and the fixed terminal 21 are arranged in parallel, the elastic part 222 is formed by bending the rear end of the fixed part 221 inward, and the outer wall of the elastic part 222 abuts against the front end of the fixed terminal 21. The contact portion 223 is formed by bending an end portion of the elastic portion 222 inward and is used for abutting against the headphone plug. A spring 23 is connected between the inner wall of the elastic portion 222 and the inner wall of the fixing portion 221. The elastic portion 222 has a certain elasticity due to its own material (copper) property, and thus, the direct connection reliability between the contact portion 223 and the earphone plug can be improved. In addition, the spring 23 is added, so that the connection reliability between the contact part 223 and the headphone plug is further improved.

Spring positioning posts (not shown) for mounting the spring 23 are provided on both the inner wall of the elastic portion 222 and the inner wall of the fixing portion 221.

The contact portions 223 of the two movable terminals 22 are arranged in a staggered manner on both sides of the insertion hole so as to abut against the earphone plug from a plurality of positions, thereby improving the connection reliability.

In addition, the end of the contact part 223 is bent outward to form a guide part 224 for guiding the insertion of the earphone plug, so that the insertion of the earphone plug is facilitated.

The spring 23 is arranged between the elastic part 222 and the fixing part 221 of the movable terminal 22, when the earphone plug is inserted into the jack, the contact part 223 is compressed, so that the spring 23 is driven to be compressed, the spring 23 can provide positive force for the earphone plug, the contact part 223 is tightly attached to the earphone plug, the contact is reliable, and at the moment, the movable terminal 22 is separated from the static terminal 21. When the earphone plug is pulled out, the spring 23 returns to a normal state, and applies force to the elastic part 222 of the movable terminal 22, so that the contact part 223 returns to an original state, and the outer wall of the elastic part 222 abuts against the end of the fixed terminal 21. The spring 23 plays a good role in springback in the whole process, and high contact reliability of the product is ensured. And, the spring has a longer service life.

Therefore, the utility model has the following advantages:

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the utility model. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
