The present invention claims the following priority: Chinese Utility Model Application No. 201520406602.7, Application Date June 12, 2015; US Provisional Application No. 62220298, Application Date September 18, 2015; and US Provisional Application No. 62281765, Application date January 22, 2016.

Technical field

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

Background technique

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 outline of the surrounding casing, 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 ensures that the terminal interface on the electrical connection 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 connection plug in the correct direction toward the electrical connection socket. This foolproof function causes the connection of the electrical connection plug and the electrical connection socket to fail, and then the user flips the electrical connection plug again to be correct. Docking. 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 Figures 15A through 15F of the 'TW Patent No. TW201440327, although the two-way electrical connector 1510 can provide a double-sided docking function, it is used to connect the contacts 1540a to 1540g and the junction contacts 1596a to 1596d of the contacts 1540h to 1540e. The structure must be carefully calculated and designed. The crossover junction boxes 1596a to 1596d can partially overlap, cross and avoid each other. Otherwise, the crossover contact frames 1596a to 1596d will abut each other and cause signal transmission errors. Among them, the manufacturing process and the assembly process of the crossover contact frames 1596a to 1596d must be strictly managed to realize the precise structure. Therefore, the manufacturing tolerance of the crossover contact frames 1596a to 1596d is small, so that one face is encountered in manufacturing and assembly. A certain degree of difficulty. In addition, since the staggered overlapping structure of the crossover contact frames 1596a to 1596d is complicated, the position of the solder joint is not fixed, and it is difficult to perform the soldering 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. This reveals that the 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.

detailed description

Although the bidirectional electrical connector described in the present invention is exemplified by an electrical connection plug, the non-limiting bidirectional electrical connector is an electrical connection plug. In fact, the bidirectional electrical connector can also be an electrical connection socket. The docked 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 unshared portion of the extension portion in the present invention, it means a structure which 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 a 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 refer to terminal pins (or pin segments), which are known in the industry.

The terminal interface referred to hereinafter as the invention may include several sections or sections, such as, but not limited to, contacts, extensions, transition extensions, stepped portions, fixed 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 the present invention may have other aspects, such as series holes, penetrating structures or side-by-side structures, etc., which are mainly fixed or electrically connected to a circuit board or other wires. 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, and a hollow space is left between the tongue plate and the insulating seat body of the present invention. In the case of a domain, the implementation of several extensions 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 depending on the actual implementation.

Referring to FIG. 1 to FIG. 4 at the same time, step A1 is first performed: the upper terminals 13a to 13d having the structure shown in FIG. 3 are provided. Next, in step A2-1, the lower extending portions 142a to 142d are bent toward the front end 123 of the tongue plate 12 in the horizontal direction X to form the lower turning extending portions 143a to 143d, and are bent in the vertical direction Y to be close to the lower contact portion 141a to The lower corner extending portions 143a to 143d of the 141d form the lower step portions 144a to 144d, that is, the step A2-2 is performed. The structure of the lower terminals 14a to 14d is as shown in FIG. In practice, the order in which steps A1 and A2 are performed may be interchanged or performed simultaneously.

Wherein, in response to the first immersed mold structure (not shown in the figure), the tongue semi-finished product 124 includes a plurality of positioning protrusions 125 and a plurality of receiving grooves 126 formed by the plurality of positioning protrusions 125, and the plurality of receiving grooves 126 respectively corresponding to and accommodate the first upper terminal 13a to the fourth upper terminal 13d. In addition, in response to the fixing element (for example, the ejector pin or the jig) in the mold structure that is first buried, the plurality of lower terminals 14a to 14d are fixed in the process, and the tongue semi-finished product 124 has a plurality of openings, and the openings are The second buried incident process is filled.

Referring to FIG. 5, after the tongue semi-finished product 124 is formed, the step A3-2 is performed: the plurality of upper terminals 13a to 13d are placed on the tongue semi-finished product 124, and the plurality of upper extending portions 132a to 132d are respectively associated with the corresponding lower extending portions 142a- 142d or more is overlapped and overlapped in parallel. The first upper terminal 13a to the fourth upper terminal 13d are respectively placed in the plurality of receiving grooves 126 as shown in FIG. The first upper contact portion 131a to the fourth upper contact portion 131d are housed in the plurality of receiving grooves 126, and the first upper step portion 133a to the fourth upper step portion 133d are respectively and are in contact with the tongue plate semi-finished product 124, and the first extending portion The 134a to the fourth extending portion 134d extend into the plurality of receiving grooves 126, respectively.

In another embodiment, the upper terminal may not be provided with an extension portion, and it may still be fixed to the tongue plate by the burying operation.

2, 3 and 5, the first upper contact portion 131a to the fourth upper contact portion 131d and the upper extension portions 132a to 132d are in a first arrangement (that is, from right to left in the figure) 131a, 131b, 131c, and 131d) are disposed, and the lower extensions 142a-142d are also disposed in a first arrangement (i.e., 142a, 142b, 142c, and 142d in order from right to left in the figure). On the other hand, the first lower contact portions 141a to 141d are provided in a manner of arranging the second circuit sequences (that is, 141d, 141c, 141b, and 141a in order from right to left in the drawing). The upper extensions 132a to 132d are respectively juxtaposed with the lower extensions 142a to 142d to which the same circuit is assigned, and do not overlap with the lower extensions 142a to 142d having the same circuit. It should be noted that the upper extending portions 132a to 132d are arranged in parallel with the corresponding lower extending portions 142a to 142d, respectively, and the upper and lower overlapping portions are different from the above-described intersecting overlapping. The intersection of the upper extension portion and the lower extension portion is vertically overlapped, and the overlapping of the upper extension portion and the lower extension portion forms an intersection structure. For example, the first lower extension portion overlaps with the first upper extension portion, indicating that the first The lower extension overlaps the first upper extension, and the first lower extension extends from the left side of the first upper extension to the right side of the first upper extension to form a cross structure.

Next, step A3-3 is performed: the upper terminals 13a to 13d and the tongue semi-finished product 124 are buried a second time to form the tongue plate 12 and the insulating seat body 11, and are extended by the upper extending portions 132a to 132d and downward. The portions 142a to 142d connect the tongue plate 12 and the insulating base 11. The upper extensions 132a-132d and the lower extensions 142a-142d that overlap each other are partially exposed outside the hollowed out region 16, as shown in FIG.

There are a plurality of base openings 111. Further, the upper extending portions 132a to 132d and the lower extending portions 142a to 142d made of a metal material have metal elasticity, and the hollowed-out portion 16 can cause the tongue plate 12 to bounce relative to the insulating seat body 11. After step A3-3, step A4 is performed: the housing 10 is sleeved and fixed on the insulating base 11.

Referring to FIG. 5, FIG. 6 and FIG. 7, after step A4, step B1 is performed: providing a plurality of wires 15, and in plural The soldering material 17 is filled in the through holes 135a to 135d to establish electrical connection between the upper extending portions 132a to 132d and the lower extending portions 142a to 142d. Next, step B2: connecting the plurality of wires 15 and the upper extensions 132a to 132d, and soldering the upper extensions 132a to 132d and the plurality of wires 15, as shown in FIG. The assembly of the two-way electrical connector 1 is completed.

Referring to FIG. 8, the upper terminals 13a-13d and the lower terminals 14a-14d are partially buried in the tongue plate 12, and the upper contact portions 131a-131d are exposed on the upper plate body surface 121 (only the second upper contact portion is shown in FIG. 131b), the lower contact portions 141a to 141d are exposed on the lower plate body surface 122 (only the third lower contact portion 141c is shown in Fig. 8). The upper extending portions 132a to 132d and the lower extending portions 142a to 142d abut each other and are partially exposed outside the hollowed out region 16, and only the second upper extending portion 132b and the second lower extending portion 142b are shown.

Next, referring to FIG. 9, when the bidirectional electrical connector 1 is mated with the complementary electrical connector 18, the complex signal interface 19 (only one shown in the figure) on the complementary electrical connector 18 abuts the upper contact portions 131a-131d, In response to the metal elasticity of the upper extending portions 132a to 132d and the lower extending portions 142a to 142d, the tongue plate 12 can be elastically moved by the plurality of signal interfaces 19 and displaced up and down with respect to the insulating seat body 11, so that the tongue plate 12 is not caused by the plural number The signal interface 19 is broken by the top. At the same time, in response to the abutment of the complex signal interface 19, the partial upper extensions 132a to 132d exposed in the hollow region 16 are slightly bent to increase the degree of contact with the lower extension portions 142a to 142d.

As can be seen from the above, each of the upper extensions 132a-132d of the present invention is separately disposed without being shared with other upper or lower extensions 142a-142d, and each of the lower extensions 142a-142d is separately provided without other The lower extensions or upper extensions 132a-132d are shared. Therefore, the arrangement of the lower turn extending portions 143a to 142d and the lower step portions 144a to 144d of the present invention can be arbitrarily bent without being in contact with each other without being restricted. The number of the lower terminals 13a to 13d and the lower terminals 14a to 14d is 4, respectively, and the number of the lower corner extensions bent toward the front end 123 of the tongue plate 12 is 3 to avoid the upper terminals 13a to 13d and the lower terminal 14a. Unnecessary contact occurs in ~14d, where unnecessary contact here means that the upper terminal comes into contact with the lower terminal having a different circuit.

As compared with the prior art, the manufacturing process and the assembly process of the lower terminals 14a to 14d of the present invention are relatively simple, and the manufacturing tolerances of the lower terminals 14a to 14d are larger than those of the prior art crossover contact frame. The manufacturing and assembly costs of the electrical connector can be reduced.
