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

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] figure 1 It is a schematic diagram of the socket of the present invention (the plug is a traditional plug). 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 socket of the present invention, 602 is a conventional plug, and 603 is a plug lead. When a traditional plug is inserted into the socket of the present invention, firstly the contact piece 104 of the plug contacts the head resistance layer 103 of the contact piece 102 of the socket, and the resistance layer realizes a current-limiting effect and eliminates contact sparks. With the further insertion 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. The socket includes socket co...

Abstract

The invention relates to power sockets, particularly to an electric spark eliminating socket and a coating production process. The electric spark eliminating socket is characterized in that the head portions of at least one group of socket contact pieces are coated with resistive layers made of resistive coatings, wherein the resistive coatings are composed of conductive fillings, substrate resin, additives and solvent. The electric spark eliminating socket has the advantages of being capable of eliminating electric sparks generated when a plug is plugged in and pulled out, avoiding corrosion or burnout of the contact pieces and accordingly being applicable to anti-explosion places. The coating process of the resistive coatings is low in cost and high in production efficiency.

technical field [0001] The invention relates to a power socket, in particular to a socket for eliminating electric sparks and a coating production process. Background technique [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, the sparks and heat of the power contacts in flammable and explosive places can easily cause explosion accidents. [0003] Chinese patent application 20141...
