Rotary type electric connection device and socket thereof

Abstract

The invention relates to a rotary type electric connection device and a socket thereof. The electric connection device comprises a plug and a socket, wherein a plugging bolt of the plug is provided with a first power electrode and a first grounding electrode; the socket is provided with a plugging bolt hole matched with the plugging bolt as well as a second power electrode and a second grounding electrode which are respectively matched and conductively connected with the first power electrode and the first grounding electrode; a part of the second grounding electrode is arranged in a guide groove rotating part to form a first arc contact part, and a second arc contact part is further formed at the tail end of the first arc contact part; the second arc contact part further extends towards a guide groove pulling-out part to form an outer convex pulling-out part; and the second grounding electrode is provided with a first spring corresponding to the second arc contact part and the back side of the pulling-out part. The electric connection device has reliable connection, and when the plug is in an unforeseen circumstance, the plug is directly pulled out from the guide groove pulling-out part to power off or reversely rotated and pulled out to power off.

Description

technical field [0001] The invention relates to an electric connection device and its socket, in particular to a rotary electric connection device and its socket. Background technique [0002] At present, a common electrical connection device is a direct plug-in type, which is to directly insert the plug of the electrical appliance into the jack of the socket with a power supply, so that the contacts on the plug and the contacts on the socket are in contact with conduction. power off. Although this traditional electrical connection device is relatively simple to use, because it relies on the resilience, delay and conductivity of the metal contact itself, the theory of improving its friction coefficient and increasing its contact area is used to complete the electrical connection. connect. Such metal contacts must have the dual functions of conduction and clamping at the same time, which is likely to cause looseness or virtual connection, and cannot ensure the reliability o...

Problems solved by technology

Such metal contacts must have the dual functions of conduction and clamping at the same time, which is easy to cause looseness or virtual connection, and cannot ensure the reliability of electrical connection

[0003] In order to overcome the shortcomings of the existing direct plug-in electrical connection devices such as poor reliability, a rotary contact type electrical connection device is also disclosed in the prior art. The device inserts the plug into the socket through the cooperation of the guide groove and the boss. , and rotate a certain distance after inserting in place, so that the contact A on the plug and the contact B on the socket engage to complete the electrical connection; The plug can only be pulled out after exiting from the original road, that is, reverse rotation to cut off the power

However, this rotating contact type electrical connection device is easy to accidentally rotate the plug when people accidentally touch the plug, which may cause the contact A on the plug to be disconnected from the contact B on the socket, thereby causing a disconnection. electric accident

Moreover, this rotary contact type electrical connection device needs reverse rotation to cut off the power, so it is troublesome to operate when emergency events such as electric shock occur, and people may forget to rotate to cut off the power in a tense state, which will cause Delays in power outages, thus missing a good opportunity to avoid accidents, so much inconvenience
