As the functions of various electronic products are becoming more and more powerful, and hand-held devices are becoming more and more popular, the demand for signal transmission between various products or devices is also increasing. signal interface. The signal interface is, for example, an electrical connector or a complementary electrical connector mated thereto, wherein the electrical connector is an electrical receptacle, and the complementary electrical connector is an electrical plug.

Before the electrical connection plug is docked with the electrical connection socket, the electrical connection plug must face the electrical connection socket in the correct direction, so that the two can be docked, that is, the electrical connection socket has a plug-in directionality, which is commonly known as foolproof. This function is to ensure that the connection interface on the electrical connection plug can be in contact with the contact terminals on the electrical connection socket. However, most users do not have the habit of facing the electrical connection plug in the correct direction to the electrical connection socket. This fool-proof function causes the connection between the electrical connection plug and the electrical connection socket to fail. After that, the user turns the electrical connection plug to connect correctly. . In other words, the fool-proof function causes trouble for the user instead.

Therefore, a bidirectional electrical connector with a double-sided butt function is provided on the market, which is provided with two sets of contact terminals to eliminate the plugging directionality of the bidirectional electrical connector.

The steel material makes the electrical connector achieve the maximum resistance to insertion and removal times.

The maximum current transmission load of the electrical connector is determined by the conductive terminal structure and conductive material. The maximum current transmission load of the electrical connector is the maximum current transmission load of the conductive grounding and power terminals, and the maximum current transmission load of the conductive grounding and power terminals. In addition to the conductivity of the conductive material, the most important thing is the size of the cross-sectional area and surface area of the conductive terminal, because the conductive material with high conductivity and the large cross-sectional area and large surface area of the conductive terminal can effectively reduce the decrease The temperature rise generated by current transmission avoids the abnormal overheating of the electrical connector. It can be seen that the current transmission load is determined by the conductivity of the conductive material and the cross-sectional area and surface area of the conductive terminal. The surface area structure of the contact parts and pins of the conductive grounding and power terminals must meet the dimensional requirements of the association's standard specifications, so it is very important to select high-conductivity metal copper materials to improve the current transmission load under the constraints of the association's specifications and dimensions. , but the selection of high-conductivity metal copper material can increase the current transmission load, but because the surface area and structure of the grounding and power terminals are still limited by the association's specifications, the overall current transmission load of the electrical connector is still greatly affected. Therefore, the inventors have devoted themselves to the research and development of ideas on how to create a breakthrough conductive terminal structure in compliance with the existing association specifications and size requirements.

In addition, the bidirectional double-sided electrical connector of the present invention has two contact interfaces, so it can also be used in conjunction with a Schottky diode, a resistor, a hypersensitive resistor, a capacitor or a magnetic bead to prevent overvoltage or overload current, or prevent overheating and high temperature or prevent short circuit. Or anti-reverse current as a circuit safety protection, but there are also many ways such as setting a Schottky diode to prevent short circuit or resistance or allergy or capacitor or magnetic beads to prevent overvoltage or overload current or prevent overheating and high temperature or prevent reverse current electronic components or prevent Short-circuit electronic components or circuit safety protection components or safety circuit setting means, so as to achieve the effect of circuit safety protection.

The above-mentioned embodiments of the electrical connection socket of the present invention can all be of a vertical type, that is, the insertion port of the connection slot is facing upward, the connecting plate is vertically extending upward, and the two connecting surfaces are vertical surfaces, and it can also be designed to be a side vertical type. , that is, the insertion port of the connecting slot faces forward, the connecting plate extends vertically forward, and the two connecting surfaces are vertical planes.

Each of the two rows of contact terminals of the aforementioned connector and socket structure can be provided with one row of horizontal pins or two rows of vertical pins.

In addition, each socket structure of the present invention can be used for board end or wire end use.

The structural features of the multiple embodiments of the present invention can be applied to each other, and two or more structural features can be combined and applied to the multiple embodiments, and for the purpose of clearly explaining the structural features of the present patent, no further additions will be made. The above-mentioned structural features are combined with each other or a plurality of similar structural features are combined with each other.

The specific embodiment proposed in the detailed description of the preferred embodiment is only to facilitate the description of the technical content of the present invention, and does not limit the present invention to the embodiment in a narrow sense, without exceeding the spirit of the present invention and the following patent application The scope of the situation can be implemented with various changes.
