Description

An expandable power strip with stable connection

technical field

The utility model relates to a socket, in particular to an expandable socket with stable connection.

Background technique

Sockets have become a must-have in people's life, study and work, but the number of sockets currently used is fixed, and the appropriate number of sockets cannot be selected according to needs. The settings are very dense, and often cannot be effectively used due to mutual obstruction when using, causing a lot of inconvenience to users during use. In the prior art, some sockets have an expansion function, and an expansion module with multiple jacks is selectively inserted on the main module as the main body of the socket, thereby increasing the number of sockets of the socket. However, when this kind of power strip is in use, the plugs inserted on the main module and the expansion module and their connecting wires will exert forces in different directions on the two, resulting in loosening of the connection between the main module and the expansion module, which is easy to cause a break. safety hazards such as fire.

Utility model content

The purpose of the utility model is to solve the technical problem in the prior art that the connection between the extension module and the main module of the expandable socket is not firm and easy to loosen, and provide an expandable socket with a stable and firm connection structure.

The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a stably connected expandable plug-in strip, including a power cord and a plug-in block with a jack, and the plug-in block consists of a main plug-in block, eight It consists of a circumferential insert block that can be used independently and eight pads that cooperate with the circumferential insert block for independent use. The top surfaces of the main insert block and the circumferential insert block are equipped with two-phase jacks and three-phase jacks. The main plug is circular and connected to the power cord. There is a power switch on its top surface, and eight expansion jacks are evenly distributed on the side for connecting the peripheral plug. The peripheral plug is wedge-shaped, and the wedge-shaped middle The end face of the smaller end is an inner concave arc whose radian is consistent with the arc of the main socket. A connecting plug matching the expansion jack is provided on the inner concave arc. The eight expansion jacks corresponding to the side of the insert block are connected, and after the connection, the sides of two adjacent circumferential insert blocks are butted together. One side is a plane, and the other side is a convex surface whose radian is consistent with the concave arc surface of the circumferential plug-in block, and a through hole corresponding to the connecting plug is provided on the pad.

The outer edge of the circumferential plug-in block of the utility model is also provided with a protruding edge which is convenient for pulling out.

The outer surface of the circumferential plug-in block of the present invention is also provided with an expansion socket.

The beneficial effects of the utility model are: the utility model arranges the row plugs in a gossip-shaped layout, the main plug is set at the center, and the circumferential plugs are matched with the expansion jacks on the main plugs to be evenly distributed on the main plugs. It can not only save the space occupied by the sockets, but also choose the number of circular inserts according to the actual needs to meet the needs of users. The structure of the sockets is simple and the layout is reasonable, which greatly improves the effective utilization rate of the sockets.

The connecting surface of the main plug and the peripheral plug adopts a circular arc design, and it will not loosen even if it is subjected to lateral forces in different directions. Moreover, the design scheme of the wedge-shaped circumferential inserts enables two adjacent circumferential inserts to abut against each other, further enhancing the firmness of the connection. Since the extended connection surface of the circumferential insert is designed in a circular arc shape, in order to make it independent, a detachable spacer is added. The spacer can complement the concave arc surface of the circumferential insert into a plane to adapt to the existing flat socket.

The utility model is also provided with a convex edge on the outer side of the circumferential inserting block, so that the circumferential inserting block is easy to pull out and plug in during use, and it is more convenient for users to use the row and plug. Expansion jacks are set on the outer surface and can be expanded according to the needs of the number of jacks.
