Problems solved by technology

[0002] The moment the electrical plug is inserted into the socket, due to the existence of a large starting current, sparks and heat will be generated at the contact point. With the stable contact between the plug and the socket contacts, the sparks and heat will disappear. When the electrical plug is pulled out When using a socket, often due to the existence of the load, sparks will also be generated at the moment when the contacts are separated. Due to the existence of electric sparks, the socket contacts and plug contacts of the socket will be continuously eroded, and in severe cases, the socket contacts and plugs will be burned. In addition, sparks and heat of power contacts in flammable and explosive places can easily cause explosion accidents

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] figure 1 It is a schematic diagram of the plug of the present invention (the socket is a traditional socket). 101 is a socket contact terminal, 102 is a socket contact, 103 is a resistance layer, 104 is a plug contact, 105 is a plug contact terminal, 601 is a traditional power socket, 602 is a plug of the present invention, and 603 is a plug lead. When the plug of the present invention is inserted into a traditional socket, at first the contact piece 102 of the socket contacts the head resistance layer 103 of the contact piece 104 of the plug. The contact piece 104 of the plug contacts the contact piece 102 of the socket, and the resistance layer 103 loses its function.

[0018] A chemical treatment production process for a socket that eliminates electric sparks, the steps of which are:

[0019] (1) Degreasing: NaOH: 100-150 g / L + Na2CO3: 20-2...

Abstract

The invention relates to power plugs, particularly to an electric spark eliminating plug and a chemical treatment production process. The electric eliminating plug comprises plug contact pieces and is characterized in that the head portions of at least one group of the plug contact pieces are provided with chemically-treated resistive layers. The chemical treatment production process comprises the steps of (1) deoiling; (2) chemical polishing; (3) pickling; (4) chemical treatment; (5) hot water cleaning; (6) saponification. The electric spark eliminating plug has the advantages of being capable of eliminating electric sparks generated when plugged in and pulled out, avoiding corrosion or burnout of the contact pieces and accordingly being applicable to anti-explosion places. The chemical treatment production process achieves spark elimination of the plug by forming the resistive layers through the chemical treatment and is efficient and simple.
