A socket for eliminating electric sparks and anodized production process

Abstract

The invention relates to power sockets, particularly to an electric spark eliminating socket and an anodizing production process. The electric spark eliminating socket comprises socket contact piece paths and is characterized in that the head portions of at least one group of socket contact pieces are provided with anodized resistive layers. The anodizing production process comprises steps of (1) deoiling; (2) chemical polishing; (3) pickling; (4) chemical treatment; (5) hot water cleaning; (6) saponification. 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 anodizing production process achieves spark elimination of the socket by forming the resistive layers through the anodizing treatment and is efficient and simple.

Description

technical field [0001] The invention relates to a power socket, in particular to a socket for eliminating electric sparks and an anodized 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 201...
