參照圖5，圖5顯示本創作防拉扯斷線的插頭結構插頭***在插座的示意圖。當本創作防拉扯斷線的插頭插在插座60的時候，電力透過插片20、彈簧30、導電片41連通至電線50，可以順利的將電力供應至電器。Referring to FIG. 5, FIG. 5 shows a schematic view of the plug structure plug of the present invention for preventing the breakage of the plug from being inserted into the socket. When the plug for preventing the disconnection of the present invention is inserted into the socket 60, power is transmitted to the electric wire 50 through the blade 20, the spring 30, and the conductive sheet 41, and the electric power can be smoothly supplied to the electric appliance.
參照圖6，圖6顯示本創作防拉扯斷線的插頭結構拉扯電線拔插頭的示意圖。當使用者以拉扯電線50的方式要將插頭拔出插座60的時候，插頭因為有插片20插在插座60的摩擦力，拉扯電線50的瞬間插頭還停留在原來位置，電線50則通過通孔12被稍微拉出外殼10之外，電線50帶動滑塊40與導電片41移動將彈簧30拉長，如此一來，電線50被拉扯瞬間的拉力則因為彈簧30被拉伸延長而緩衝，一部分拉力被彈簧30變形吸收，因而可以降低對電線50內部導線的拉力、也可以降低電線50與導電片41接點的拉力，使電線50的金屬導線與插頭內的各個電性接點都可以避免被拉扯斷線。Referring to FIG. 6, FIG. 6 shows a schematic view of the plug structure for pulling the broken wire of the present invention. When the user pulls the plug out of the socket 60 by pulling the wire 50, the plug has the frictional force of the insert 20 inserted into the socket 60, and the moment the cable 50 is pulled, the plug remains in the original position, and the wire 50 passes through. The hole 12 is slightly pulled out of the outer casing 10, and the electric wire 50 drives the slider 40 and the conductive piece 41 to move to lengthen the spring 30. Thus, the pulling force of the wire 50 being pulled instantaneously is buffered by the extension of the spring 30. A part of the pulling force is deformed and absorbed by the spring 30, so that the pulling force of the inner wire of the electric wire 50 can be reduced, and the pulling force of the contact between the electric wire 50 and the conductive piece 41 can be reduced, so that the metal wires of the electric wire 50 and the electrical contacts in the plug can be Avoid being pulled off.
參照圖7，圖7顯示本創作防拉扯斷線的插頭結構拉扯電線拔插頭的動作示意圖。拉扯電線50初期的一部分拉力被彈簧30變形吸收，之後彈簧30的變形回復力傳遞至插片20而克服插片20與插座60的摩擦力，使插頭自插座60中移出。Referring to FIG. 7, FIG. 7 is a schematic view showing the action of pulling the plug by pulling the plug of the plug structure of the present invention. A part of the pulling force at the initial stage of pulling the wire 50 is deformed and absorbed by the spring 30, and then the deformation restoring force of the spring 30 is transmitted to the blade 20 to overcome the frictional force of the blade 20 and the socket 60, so that the plug is removed from the socket 60.
參照圖8，圖8顯示本創作防拉扯斷線的插頭結構插頭拔離插座的示意圖。當插頭拔離插座60之後，彈簧30的回復力使本創作防拉扯斷線的插頭結構內的各個元件回復原來位置。當經常以拉扯電線50的方式拔插頭時，本創作的實施例的結構都能在每次的拉扯緩衝拉力，能有效避免因為拉扯電線導致插頭發生斷路、短路或接觸不良的情況發生。Referring to FIG. 8, FIG. 8 is a schematic view showing the plug structure plug of the present invention for preventing the disconnection of the plug from being pulled out of the socket. When the plug is removed from the socket 60, the restoring force of the spring 30 causes the various components within the plug structure of the present invention to be broken and returned to their original positions. When the plug is often pulled in such a manner as to pull the electric wire 50, the structure of the embodiment of the present invention can pull the buffering force at each pulling, and it is possible to effectively prevent the plug from being broken, short-circuited or poorly contacted due to pulling the electric wire.
