According to the advancement of electronic technology, many electronic and electrical products bring people comfort and convenience in work and life, and people are increasingly relying on the use of electronic and electrical products. Through the application and operation of various electronic signals. Control the operation and execution of electronic and electrical products, as well as the continuous improvement and creation of various electronic and electrical products. The functions of various electronic and electrical products must be continuously updated and replaced, and the application of electronic signals is required. Control the operation and execution capabilities of electronic and electrical products, and the speed of electronic signal transmission is constantly increasing. Electronic signals must be transmitted between electronic and electrical products through various transmission interfaces, electrical connectors, etc., and electronic signals are transmitted. The transmission interface is also constantly improved and innovated to improve the transmission interface of electronic signals, the type and quality of electrical connectors, and the speed of transmitting electronic signals. However, there are quite a variety of types and types of electronic signal transmission interfaces. The size of the signal transmission interface and the electrical connector are also different. The pattern is different, the product must be installed on the electronic transmission of many types of interface specifications, electrical connectors, electronic products to meet the feed There is a need for various types of electronic signal transmission, so there must be enough space on various electronic products to install various types of transmission interfaces and electrical connectors.

Among the types of electrical connectors that are commonly used in today's electronic devices, the universal serial bus (USB) specification is the most widely used electrical connector, and varies with the specifications of the universal serial bus, such as USB2.0, USB3.0. , Micro Universal Serial Bus (Micro USB), Mini Universal Serial Bus (Mini USB) or Universal Serial Bus Type-C, etc., can be used in a variety of applications, including Universal Serial Bus Type-C Specifications The female connector is provided for the male connector to be plugged in the front type or the reverse type, and the terminal block of the universal serial bus type Type-C female connector includes the tongue on the butt joint The lower surface is opposite to the plurality of upper rows of terminals and the plurality of lower row of terminals, and the plurality of upper and lower rows of terminals comprise terminal groups for transmitting high frequency, low frequency and power, and the tongue plate is still in place at the butt joint portion. The detection terminal, in addition, in order to cope with the interference caused by high frequency transmission or noise, it is convenient to arrange a metal partition between the plurality of terminals on the tongue plate and the lower row, and the metal separator is placed on the upper row. Terminal, plural lower row Between the insulating rubber seats, the female connector can be formed as a female connector, and the two sides of the tongue plate are provided with grooves for elastically holding the left and right fixed terminals of the male connector insertion portion, and the metal partition The two side edges of the board are also located at the recesses to prevent damage to the tongue of the insulating rubber seat during plugging and unplugging. However, the universal serial bus type Type-C is a new type of connector, and the female connector has a large number of terminals. The overall width is limited, so the multiple welded ends need to be arranged in a multi-linear line, but because the multiple rows of welded ends have the problem of being difficult to weld, it not only causes the occurrence of voids or short circuits during welding, but also is difficult to detect when reflow or It is also difficult to handle during desoldering, so it needs to be processed through a special machine, so it has the problem of troublesome handling and high cost. If the female connector is used only with low frequency signals. Electronic devices (such as mobile phones, tablets, etc.) do not need so many terminals, so you can omit the high-frequency signal terminals and only need to keep the low-frequency signals and power terminals, and such low-frequency signals In addition to the need to consider whether the overall structure is streamlined and low in cost, the female connector must also consider the convenience of the female connector in soldering. Therefore, how to solve the above-mentioned lack of inconvenience and inconvenience, that is, the relevant industry I want to study the direction of improvement.

Therefore, in view of the above problems and deficiencies, the creators have collected relevant information, and through multi-party assessment and consideration, and through years of experience in the industry, through continuous trial and modification, we have designed such convenient welding, testing and Subsequent processing and low cost of the original creation of the patent for the electrical connector that can be inserted and removed.

The main purpose of the present invention is to provide a plurality of low-frequency signals, a power source and a plurality of docking terminals for use on the ground and the lower surface of the base, and the butt joints of the butt joints are formed along a downwardly bent portion. The welded part exposed outside the base reduces the number of welded parts by saving the high frequency and its corresponding grounding complex butt joints. Therefore, the plurality of welded parts can be arranged in a straight line, and it is not easy to generate holes or short circuits during welding. There is no problem that multiple rows of welds are blocked during welding or desoldering, which has the effect of facilitating welding, testing and subsequent processing, thereby reducing costs.

The second purpose of this creation is that the female connector saves the high frequency signal transmission and its corresponding grounding multiple docking terminal, so that the female connector has no high frequency transmission or miscellaneous between the upper and lower sides. The interference generated by the signal can save the metal partition between the plurality of terminals of the row and the lower row on the tongue plate, and the component is reduced, thereby achieving the purpose of reducing the cost.
