Power connection module

The present invention provides a power connection module, in particular, the plug and the socket utilize a central probe and a conductive terminal and a conductive outer casing to electrically contact the conductive housing to transmit power, and the magnetic element and the magnetic element form a magnetic state, Prevent the plug from falling easily after being plugged in.

According to the plug and the socket, the plug and the socket have a close relationship with each other. Since the invention of the plug and the socket, with the popularization of electronic products, the application thereof is more widely used, such as in the home or office, the electronic products and plugs are everywhere. And the trace of the socket, when the plug and the socket are used as the interface for transmitting power, the power is connected to the electronic product through the plug and the socket for operation, but since the plug is usually connected with a wire, the user often occurs. If you accidentally kick or pull the wire, the plug will be disconnected from the socket. In serious cases, the electronic product will fall and fall.

Therefore, some manufacturers have developed plugs and sockets for magnetic adsorption on the outside of the power plugs and sockets. After the power plugs and sockets are connected, the two magnetic components are connected to each other. Close to and use magnetic force to form the adsorption, so the power plug can be disengaged from the socket without being touched by magnetic attraction, and when the user accidentally kicks or pulls the wire, the force greater than the magnetic attraction will cause the power plug When you leave the socket, you can prevent electronic products from falling and falling.

However, the power plug and the socket are externally provided with magnetic components, so the size of the plug and the socket is increased.

Figure, another perspective exploded view, a side cross-sectional view before plugging, a side cross-sectional view after plugging, and a top cross-sectional view after plugging, it is clear from the figure that the plug 1 is docked with the socket 2. When the plug 1 is placed in the slot 240, the plug 1 is placed in front of the conductive housing 15 The ring recess 214 of the socket 2 causes the two resisting elastic arms 243 to elastically resist the conductive outer casing 15 to make the plug 1 difficult to loosen, and the front end of the probe 13 of the plug 1 is in contact with the conductive terminal 23 of the socket 2 to form an electrical connection. The probe 13 can elastically expand and contract with the insertion of the plug 1, and the front end of the terminal 141 is pressed against the magnetic element 22 of the socket 2, and then displaced rearward, and the elastic force is caused by the stopper ring 1411 against the elastic member 143. The deformation of the arc-shaped portion 1441 of the elastic piece 144 is elastically deformed backward. When the plug 1 is continuously inserted into the inner side of the slot 240, the arc-shaped portion 1441 is electrically contacted with the contact terminal 145, and at the same time, the plug 1 is The magnetic element 12 is in contact with the magnetic element 22 of the socket 2 (or has only a slight gap) to form a magnetically adsorbed shape.

By switching the module 14, the power can be turned off first, and the push terminal 141 pushes the shrapnel. After the arc-shaped portion 1441 of the 144 contacts the contact terminal 145, the signal is sent to turn on the power. At this time, since the probe 13 and the conductive terminal 23 are in positive electrical contact, an instantaneous current can be avoided and a spark or an arc can be generated. It can prevent the spark or arc from forming scorching and cause the problem of poor electrical conductivity, thereby improving the safety of use and maintaining good electrical conductivity. When the plug is removed, the power can be restored due to the separation of the elastic piece 144 from the contact terminal 145. Is closed.
