According to the current situation, the power used in electronic devices or home appliances in daily life is mostly based on AC power. It only needs to have related circuits and equipment to extend the power beyond the current limit. Generally, it is connected to the mains through a power socket provided indoors or outdoors, so that the power cord plug of the electronic device or the home appliance can be directly plugged into the power socket to provide the overall required power.

In addition, the power sockets in general homes, offices, etc. are mostly fixed on the wall, decorative panels, siding, shelf or other wall. If the electronic device or home appliance is located far from the power socket and is limited by itself When the length of the power cord is not enough, the extension cord is used to effectively extend the distance between the power sockets, and the power cord plugs of the plurality of electronic devices or home appliances can be plugged and used by the sockets on the extension cord, but the current market extension The number of power sockets of the line is fixed and cannot be increased or decreased according to the demand or the place of use. In addition, the size of the transformer plug on the power line of the electronic device is different, and the power supply of the adjacent line on the extension line is also occupied. The location of the socket cannot be fully utilized, resulting in the user having to purchase multiple extension cords to provide a certain number of power outlets, so that the overall effect will be limited, and the multiple extension cords will cause use and cable management. The trouble of storage, but also increase the cost of users, is a drawback of the United States, so how to overcome the problem that the power socket can not expand the connection and use it, is the key to redesigning the people in this industry. .

Therefore, the inventors have drawn up the relevant problems and defects in the use of power outlets, and collected relevant data through multi-party evaluation and consideration, and continuously tried and modified the years of research and development experience in this industry, and designed the series power socket structure. The invention patent was born.

According to actual needs or different places of use, a plurality of adjacent socket bodies can be modularly connected and expanded in a horizontal direction, so as to avoid the use of multiple extension cables, which causes troubles in use, cable management and storage. Reduce the cost of purchasing multiple extension cords, and make it more practical and applicable.

The secondary object of the present invention is that the substrate of the socket body is formed in a suspended state by the perforation at the rear wall surface of the abutting portion of the outer casing, so that the substrate can be hidden inside the butting portion without being exposed to avoid conduction through the human body or the hand. The object accidentally touches the conductive terminal on the substrate The damage caused by electric shock can improve the safety of use, and the substrate is matched with the conductive terminal in a flat shape, and the thickness thereof is further reduced compared with the general double-row power socket, thereby reducing the volume occupied by the socket body. It is thinner to facilitate placement or storage.

Another object of the present invention is that the abutting portion of the socket body is further provided with a positioning portion for connecting the plug to the side of the base body, and has a second slot for inserting the substrate on the positioning portion, and the positioning portion is The other side is provided with a plug portion having a plurality of conductive inserts, and the two sides of the plug portion are respectively provided with connection terminals electrically connected to the conductive inserts, and have contacts for the conductive terminals on the connection terminals.
