Description

Multi-conductive-point protection socket

Technical Field

The invention belongs to the technical field of electrical switch control, and relates to a multi-conductive-point protection socket.

Background

The power socket is an interface device for providing power connection for electrical equipment, and has wide application in household life and scientific research and teaching. The use of various non-standard plugs can cause damage to the electric equipment. Especially in the places such as families, kindergartens, schools and the like, the personal safety can be even harmed by the mistaken insertion of metal foreign matters or water-stained articles. In order to ensure the safety of electricity consumption in the use environment, a power socket with electric shock resistance and water splashing resistance needs to be designed.

The existing electric shock protection power socket mainly comprises the following methods: independent switch protection, slot protection, cross-loop protection, etc. The independent switch protection method is characterized in that an independent switch for controlling the connection of a power supply is arranged beside each socket, and the power supply is connected by pressing the switch in advance during normal work. In fact, the power socket of the protection mode does not have the function of preventing misplug, the operation is relatively complicated, and the situations of mistaken pressing, missed pressing and the like are easy to occur in the using process. The slot protection method is characterized in that a sheet shielding jack is arranged at a power supply slot, and the sheet shielding jack can be inserted and connected with a power supply only by removing the shielding sheet or rotating a plug for a certain angle during working. The protection mode has better misplug prevention effect, but has poorer protection effect on the insertion of certain metal foreign matters. The cross loop protection method achieves the aim of electric shock resistance by designing a plurality of conducting loops in an internal electric structure. The protection method has ingenious structural design and improves the misplug prevention function of the power socket. The current prevent that it leads electrical trigger device to be located socket upper portion among the misplug protection mode to inserted sheet and electrically conductive clamping piece fixed contact, safety protection nature is relatively poor. The existing power socket protected against water splashing mainly has two methods of mechanical water proofing and mold water proofing. The design of the conductive contacts or conductive loops is mainly adopted in the mechanical waterproof mode to ensure that the socket is not electrified under the condition of water splashing. Mainly comprises a permanent magnet type, a four-contact cross loop, a conducting piece and a plug contact piece. The method has a certain water splashing prevention function, but has a poor protection effect when the water amount is large. In the waterproof mode of the mold, a waterproof cover or a waterproof sheet is usually arranged at the slot, and a water chute is arranged in the socket for draining water to ensure that the socket works normally. The method has good waterproof effect, but is inconvenient to use and operate in daily life.

The advantages of the invention are explained by using the working principle:

the protection socket with multiple conductive points realizes the function of electric shock prevention by adopting a six-contact cross loop and press contact conduction;

under the normal working condition, when a plug which meets the electrical standard regulation is inserted into two wire inserting holes 2 of a socket, the inserting sheet simultaneously extrudes a conductive block 4 and an insulating block 3 which are positioned at two sides of the two wire inserting holes 2, so that conductive contacts corresponding to a metal elastic sheet 5 and a metal elastic sheet A6 are contacted with a conductive loop, thereby realizing electrical connection, the tail end of the inserting sheet respectively pushes down the bottom of a closable conductive clamping sheet 9, so that the bottom of the conductive clamping sheet is respectively electrically connected with the corresponding conductive contact, namely the metal elastic sheet A6, simultaneously, the inserting sheet pushes down to trigger the closable conductive clamping sheet 9 to be closed and clamp the inserting sheet, thereby realizing electrical connection, when the plug is completely inserted into the socket, the bottom of the socket is contacted with an insulating ball 7 and downwards pushes insulating blocks 8 connected with two ends of the socket, so that the metal elastic sheets 5 connected with the insulating blocks 8 are respectively electrically connected with conductive contacts connected with a live wire and a zero wire, and after the, the electric conduction of the cross loop is realized, and the socket is connected with a power supply to work normally;

under the abnormal working condition, when non-standard plugs, metal foreign bodies (tweezers, screwdrivers, iron wires and the like) and conductive media (human bodies and wet objects) are forcibly inserted into the socket, the sizes of the non-standard plugs, the metal foreign bodies and the conductive media do not accord with the corresponding regulations of the national electrical standards, six conductive contacts cannot be simultaneously closed, the electrical conduction of a cross loop cannot be realized, and the power socket cannot normally work, so that the protection functions of electric shock prevention and mistaken insertion prevention are achieved.
