The plug should be able to be pulled out of the socket without having to hold the socket with one hand and withdraw the plug with the other hand (such as a variable position such as a known triple or five-level ground socket). ... especially in old-fashioned buildings, when pulling the plug with one hand (often simply by pulling the cable), there is a danger that the application of force will result in a peg, usually fixed by plaster. The fixing structure of the power socket in the wall becomes loose, but the power socket is still hanging on the wire. This is very dangerous. For people with disabilities, such as people with only one hand or paralyzed hand, pull the plug. It is usually difficult. 1 The disadvantages of the above-mentioned known plugs with a discharge device are that they are either unsuitable as protective contact plugs due to their structural principles, or they are very complicated to manufacture and install. M253966 [New content] The purpose of this creation is to provide a protective contact plug with a life-recognition device, which can be easily manufactured and installed. The same reference numerals are used to indicate the same components or parts. According to this creation, this task is accomplished by a protective contact plug,

Here, other parts can also be designed to be conductive, if this is desired or appropriate. The feature of another embodiment of the plug with a guaranteed connection according to the present invention is that the ejection device 22 has a relatively arm 22b for pressing the plug out of the socket and a support for supporting the bottom surface of the socket. The shorter ^ # 22a. The length of the arm is not limited in principle and is selected by a technician based on the actual situation. The only thing that matters is to be strong enough: leverage. For example, the arm used to press the plug out of the socket can also be compared, if this is desired or appropriate. The two branches can also have the same length. The angle formed by arranging the support arm in the case of forming the ejection device according to the present invention: It was originally not particularly limited, as long as it can achieve a sufficiently strong leverage. The appropriate angle or range of angles can be determined by the technician without any difficulty based on experience. B. Features of another embodiment of the protective contact plug according to the present invention 疋 In the socket, a hinge point is eccentrically disposed toward the free end of the longer arm 22b of the discharge device 22. The hinge point may also be in another position 'if this is desired or appropriate. Features of another embodiment of the protective contact plug according to the present invention M253966 疋 'The side of the shorter arm 22a of the discharge rack 22 has no first contact surface connected to the two conductive wires of the cable, and is connected to the discharge device 22 None of the sides adjacent to the side of the shorter arm 22a has a contact surface connected to the contact pins 16, 18 ^ These conductive structures are only exemplary, and there is no particular limitation on the conductive structure. Another embodiment of the protective contact plug according to the present invention is characterized in that a first protective contact 20, 21 is arranged on the outward-facing surface of the shorter arm 22a of the discharge device 22. A further embodiment of the protective contact plug according to the present invention is characterized in that a second protective contact 20, 21 mounted on the housing 10 is electrically connected via an outlet device 22 and is assisted by holes 33, 34.

With regard to the arrangement, type or number of protective contacts in the housing 10 of the protective contact plug of the present creation In principle, there are no restrictions on the form of supply, power supply or electrical contact or electrical connection. In particular, 'all standardized or canonical ^ header types are suitable. The housing 10 for protecting the contact plug, the ejection device 22, and other components or parts may be made of a suitable or commonly used material such as plastic. This case is similarly applied to the contact pins 16, 18 and the protective contacts 20, 21 and other conductive members or parts. 〃 Another embodiment of the protective contact plug according to this creation is' the electron microscope is inserted in the discharge 奘 罟 9 9 94 ek, " between the clamps of the longer arm 22b of the table 22 or between The pliers between the arms used to press the plug out of the socket advantageously prevent a sweet rebound. In addition, in another preferred 2 form, a groove or is provided on the end of the longer arm of the discharge device (or on the end of the arm for pressing the plug out of the socket). An electron microscope inserted between the tongs between the forceps passes through the groove or hole. Of course, these electrical fiber supplies are only exemplary, and there are no special restrictions in principle. For example, the discharge device may be located on an electrical environment. Alternatively, springback can also be prevented by placing corresponding shawl or dagger mechanism elements between pliers, preferably in the lower area of the ejection device. H According to another embodiment of the protective contact plug created by this invention The characteristic% is 'the cable is externally injection-molded in the housing!'. In this way, there is no need to guide the cable through a hollow shaft and to make contact through assembly.
