Positive and negative pluggable power connector

The present invention provides a power connector that can be inserted and removed in the front and back, especially the male connector body is provided with a plurality of vertical flat plug terminals, and the insertion space of the plug terminal is available for the mother. Two sets of power supply and grounding butt joints on the lower surface of the connector's tongue and the board are used in electrical contact with the lower arm above the plate-shaped terminal plug-in part.

According to the current type of electrical connectors frequently used in electronic devices, the universal serial bus (USB) specification of electrical connectors is the most widely used, 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 the universal serial bus type -C specification terminal group includes upper and lower relative upper row of terminals and plural lower row of terminals, and metal separators are arranged between plural upper row terminals and plural lower row ends, in order to connect terminal groups and metals The electrical connector of the type-C specification of the general-purpose serial busbar of the baffle forming must be subjected to a plurality of processing operations, respectively, after the externally-disposed terminal blocks and the plurality of lower-end ends are externally formed with the insulating rubber seat, and the metal separator is sandwiched in the plural The upper terminal and the lower terminal of the insulating rubber seat are plastic injection processed before they can be molded into a female connector. However, in today's male connector, it is often only used for many applications. The female connector Power supply or charging is used on the device side (such as mobile phone, tablet computer, etc.), so the number of terminals used by the male connector can omit the signal terminal and only need to retain the power supply and ground terminal, but in order to be in the front type or The reverse type plug-in female connector, the plurality of power supply and the grounding terminal of the male connector are also in the upper two rows of the symmetrical position, but the position of the terminal for omitting the complex signal is a clear state, and the overall structure is complicated and the design is not easy. Generally, the male connector of the cable is in two ways, one is to directly solder the male connector to the plurality of conductors of the wire, and the other is to use the plurality of conductors of the male connector and the wire. At the same time, it is soldered to a circuit board, and after the above two methods are completed, it is required to be formed with an insulating material outside the insulator of the male connector near the soldering portion and the conductor of the wire, which is a complete wire end male connector. In addition to the need to consider whether the overall structure is streamlined and positioned correctly, the male connector used for such power supply or charging should also consider the male connection when plugging in. And the stability of the complex conductor wire of the force, is, how to try to solve the above-mentioned lack of conventional and inconvenience, anxious to study the related industry is the direction of improvement lies.

Therefore, in view of the above-mentioned shortcomings, the creators have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, we have designed such a positive and negative pluggable power connection. A new patent for the device.

The main purpose of the present invention is to provide a plurality of tuning fork type plate terminals for power supply and grounding, and a plug portion for forming a space in front of the plurality of plate terminals, so that the elastic parts of the respective insertion portions can be clamped. Hold the lower surface of the tongue and plate in the mating space of the female connector, and at the same time make the power supply and grounding butt terminal of the lower surface of the base connector of the female connector electrically contact with the upper elastic arm of the plate terminal insertion portion, so each A plate-shaped terminal can be used with the female connector on the tongue plate The surface power supply and the grounding terminal are electrically connected to reduce the assembly difficulty of the male connector, and the plate terminal has the advantages of easy processing, low cost and increased structural strength.

The secondary purpose of this creation is that the power supply and grounding plate terminals in different positions are respectively bridged by a connecting portion to form a common circuit for power supply stability.
