Description

Two-way electrical connector 【Technical Information】

The case claims the priority of the following applications: Chinese utility model application number 201520406602.7, application date June 12, 2015; US temporary application number 62220298, application date September 18, 2015; and US temporary application number 62281765, application date January 22, 2016.

The present invention is directed to a two-way electrical connector, and more particularly to a two-way electrical connector that is electrically coupled to an external circuit board by mating with a complementary electrical connector.

As the functions of various electronic products are becoming more and more powerful, and handheld devices are becoming more and more popular, there is an increasing demand for signal transmission between various products or devices; accordingly, how to reduce the size of products or devices in the shell In the contour of the body, it is the joint goal of the industry to provide more terminal interfaces for signal transmission with different devices (for example, two-way electrical connectors or complementary electrical connectors that are connected thereto). The two-way electrical connector is an electrical plug, and the complementary electrical connector is an electrical receptacle.

Before the electrical connection plug and the electrical connection socket are docked, the electrical connection plug must be oriented in the correct direction toward the electrical connection socket, so that the two can be docked, that is, the electrical connection socket has a plug-in directionality, which is commonly known as a foolproof Function, this function is to ensure that the terminal interface on the electrical connector plug can be in contact with the connection interface on the electrical connection socket. However, most users do not have the habit of connecting the electrical connector plug in the correct direction toward the electrical connection socket. This foolproof function causes the electrical connection to be inserted. The docking of the head and the electrical connection socket fails, and then the user flips the electrical connection plug again to be properly docked. In other words, this foolproof function causes confusion for the user.

Therefore, an electrical connection plug having a double-sided docking function is provided on the market, and an electrical connection plug is disclosed in Japanese Patent Laid-Open Publication No. TW201440327. Referring to FIGS. 15A to 15F of the TW201440327 patent, although the two-way electrical connector 1510 can provide a double-sided docking function, it is used to connect the junctions 1540a to 1540g and the junctions 1540h to 1540e of the crossover junction frame 1596a. The structure of ~1596d must be carefully calculated and designed. The crossover frames 1596a~1596d can partially overlap, cross and avoid each other. Otherwise, the crossover contact frames 1596a~1596d will abut each other and cause signal transmission errors. Among them, the manufacturing process and assembly process of the crossover joint frame 1596a~1596d must be strictly managed to realize the precise structure. Therefore, the manufacturing tolerances of the crossover contact frames 1596a to 1596d are small, so that a certain degree of difficulty is encountered in manufacturing and assembly. In addition, since the staggered overlapping structure of the crossover contact frames 1596a to 1596d is complicated, the position of the solder joints is not fixed, and it is difficult to perform the welding work, which further increases the difficulty in manufacturing and assembling.

In addition, there are also a number of patent publications or patents that disclose two-way electrical connectors, such as Chinese Patent Application No. 201420215601, Chinese Patent Application No. 201420486606, or Chinese Patent Application No. 201520562191, and the like. The disclosed two-way electrical connector has several problems in practical applications, such as an increase in manufacturing or assembly difficulty, an increase in manufacturing or assembly costs, or an improper use of a short circuit, resulting in a failure to provide a friendly use manner and the like. Therefore, the development of two-way electrical connectors, especially two-way electrical connectors compatible with existing USB A types, continues to progress.

One of the purposes of this case is to provide a two-way electricity that can be easily manufactured and assembled. The connector, which has a two-way electrical connector with a double-sided docking function, is compatible with the existing USB A-type electrical connection socket or plug.

One of the purposes of the present invention is to provide a two-way electrical connector that can be easily used. In the process of docking a bidirectional electrical connector and a complementary electrical connector, the structure and action of the tongue of the bidirectional electrical connector can avoid the occurrence of a short circuit and is convenient to use. Use.

One of the purposes of this case is to provide a two-way electrical connector whose contact portion is designed to improve the communication between the electrical signal and the current, and optimize the performance of the two-way electrical connector. Therefore, the two-way electrical connector of the present invention can meet higher specifications or standards. Claim.

Although the two-way electrical connector described in the present invention is exemplified by an electrical connection plug, the non-limiting two-way electrical connector is an electrical connection plug. In fact, the two-way electrical connector can also be an electrical connection socket. The complementary electrical connector is an electrical connection plug. That is, when the bidirectional electrical connector is an electrical connection plug, the complementary electrical connector is an electrical connection socket. Conversely, when the bidirectional electrical connector is electrically connected to the socket, the complementary electrical connector is an electrical connection plug.

The upper and lower extensions of each of the upper and lower terminals are also separately provided without being shared with other lower extensions or upper extensions. As for the non-common of the extension portion in the present case, it is a structure that is not integrally formed with other extension portions but is separately provided.

In addition, the terminal interface of the present invention can be connected to the wire, and the wire can be connected to the circuit board to establish an electrical connection between the terminal interface and the circuit board. However, the wires are not limited to metal wires only, and may also be referred to as terminal pins (or pin segments), which are known in the industry.

The terminal interface referred to hereinafter may include a plurality of sections or portions, such as, but not limited to, contact portions, extensions, transition extensions, step portions, fixing portions and pins, and the like. In different implementations, the terminal interface may include sections or portions that differ, but are all part of the terminal interface of the present invention. Secondly, the pins referred to in this case may have other aspects, such as series holes and penetration. Structures or side-by-side structures, etc., are primarily fixed or electrically connected to a circuit board or other wire. The contacts are primarily in contact with the mating complementary electrical connectors. The extension portion is mainly extended between the tongue plate and the insulating seat body. When the hollow portion is left between the tongue plate and the insulating seat body in the present case, the implementation manner of the plurality of extension portions can be bounced. The fixing portion mainly positions the terminal interface into the insulating seat body, and is usually covered in the insulating seat body. However, the functions of the above sections of the present invention are not limited thereto, and may be slightly adjusted according to actual implementation aspects.

In the following, a number of preferred embodiments are further described to illustrate the present invention, which is well known to those skilled in the art, and is not intended to limit the invention or the creation itself.
