Plug, socket and electric connection device with plug and socket

Abstract

The present invention relates to an electric connection device, pin and socket. The electric connection device comprises of at least one pin which has an inserted blot whose outer wall has at least one first metal touching point connected to lead, a first contact surface is set inclined to the first prearranged angle; and at least one socket which has inserted hole matched to inserted bolt whose hole wall has at least one second metal touching point which is corresponding to the first metal touching point to form a second touching surface with a prearranged radian, and a guide groove guides the inserted blot rotating a second prearranged angle and contract friction touching between the first metal touching point and the second metal touching point. The present invention can realize credible electric connection, has a simple structure and convenient operation.

Description

technical field [0001] The present invention relates to a plug, a socket and an electrical connection device with a plug and socket, in particular to a rotary contact retreat locking type electrical connection device and its plug and socket, which are suitable for electrical plugs and common sockets, wiring boards and cassettes Sockets, special active sockets, etc. Background technique [0002] At present, the common electrical connection methods and devices are all direct plug-in type, which connects when plugged in, and disconnects when pulled out. Although this traditional electrical connection method and device is relatively simple to use, it is based on the theory of the resilience, delay and conductivity of the metal contact itself, improving its friction coefficient and increasing its contact area. Complete the electrical connections. Such metal contacts must have the dual functions of conduction and clamping at the same time, which is likely to cause looseness or v...

Problems solved by technology

[0004] The metal contact of the above-mentioned rotary spring-back electrical connection device mainly completes the conductive function, and the clamping function is mainly completed by an ad hoc mechanism (that is, the guide groove on the plug cooperates with the safety protection boss), and the spring ensures that The electrical connection between the metal contacts improves the reliability of the electrical connection to a certain extent. However, the above-mentioned rotary rebound type electrical connection device still has certain defects, such as: complex structure, which not only needs to be connected to the plug A J-shaped guide groove is processed on the top, and a safety protection boss is processed on the wall of the plug hole to ensure the clamping and locking of the plug and the socket; and a spring with a high elastic force requirement must be set to ensure that the plug is locked. The metal contacts on the socket are in full contact with the metal contacts on the socket to achieve electrical connection

In addition, after long-term use, the protruding safety protection bosses are prone to deformation or even fall off, thereby reducing the reliability of electrical connections

Moreover, when the plug hole of the socket is upward, the surface of the metal contact is easy to accumulate dust, which will cause the surface of the electrode to be polluted, which will easily cause poor contact and arc light when plugging and unplugging.

especially for figure 1 For the structure in which the metal contacts touch up and down to realize electrical connection, the surface contamination of the electrodes is more likely to cause poor contact and arcing.
