The conical plug pin and the plug bush disclosed by the invention can be applied to various electricity consuming occasions.

Description

Tapered pin and sleeve for socket and plug

technical field

The invention relates to a pin and a socket, in particular to a tapered pin and a socket for a socket and a plug.

Background technique

Existing bolts and sockets all adopt plate clamping structure. Practice has shown that due to the limitations of their own structures, such plugs and sockets generally have the problems of loose contact, large contact resistance, small effective contact area, and easy to burn out due to heat, which leads to poor safety and reliability of electrical connections, thus affecting safety. Electricity poses a great danger. Based on this, it is necessary to invent a brand-new latch and socket to solve the above-mentioned problems existing in the existing latch and socket.

Contents of the invention

In order to solve the existing problems of loose contact between pin and socket, large contact resistance, small effective contact area, and easy heating and burning, the present invention provides a tapered pin and socket for sockets and plugs.

The present invention is achieved by adopting the following technical solutions: a tapered pin and sleeve for sockets and plugs, including a socket part and a pin part; the socket part includes a tapered sleeve and a disc-shaped connecting plate; the plug The part includes a tapered pin head, a disk-shaped positioning platform, and a cylindrical connection head; the thin end of the tapered sleeve is closed, and the thick end of the tapered sleeve is provided with an opening; the center of the upper surface of the disk-shaped connecting plate It is fixed with the thin end face of the tapered sleeve; the thin end of the tapered pin head is movably inserted into the inner cavity of the tapered sleeve; the center of the lower table of the disc-shaped positioning table is fixed with the thick end face of the tapered pin head Integral; the lower end surface of the cylindrical connector and the center of the upper table surface of the disc-shaped positioning table are fixed as a whole.

When in use, connect the disc-shaped connecting plate with one end of the electrical circuit, and connect the column-shaped connector with the other end of the electrical circuit. The specific use process is as follows: insert the thin end of the tapered pin head into the inner cavity of the tapered sleeve, and then the electrical circuit is connected. On the contrary, when the thin end of the tapered pin head is pulled out from the inner cavity of the tapered sleeve, the electrical circuit is disconnected. During this process, the disc-shaped positioning platform acts as a limit, which can prevent the tapered pin head from being difficult to pull out due to too tight insertion. Based on the above process, compared with the existing pins and sockets, the tapered pin and socket for sockets and plugs according to the present invention adopts a tapered fitting structure, so that the contact between the pin and the socket is tighter, The contact resistance is smaller, the effective contact area is larger, and heat and burnout are effectively prevented, thereby effectively enhancing the safety and reliability of electrical connections, thereby effectively ensuring safe electricity use.

The invention effectively solves the problems of loose contact between the existing plug pin and socket, large contact resistance, small effective contact area, and easy heating and burning, and is suitable for various electricity use occasions.
