AI Technical Summary
The existing holeless sockets have shortcomings in the anti-single voltage function, and cannot effectively avoid circuit short circuits and electrical safety hazards caused by contact between the fixed conductive sheet and the rotating conductive sheet on the side of the pin without inserting it.
A two-core and three-core combination non-hole socket is designed. By setting a three-core and two-core protective door assembly in the socket, the structure of an anti-single-pressure slider and a sliding conductive sheet is used to ensure that the sliding conductive sheet is pressed and the fixed conductive sheet is achieved when the pin is inserted, and the circuit is turned on; and when only one side of the pin is inserted, the anti-single-pressure slider cannot move, avoiding the fixed conductive sheet and contacting the sliding conductive sheet, ensuring that the circuit is disconnected.
This design effectively avoids circuit short circuit of the socket when the single-side pin is inserted, ensures the socket's anti-single voltage function and improves the user's personal safety.

Technical Field
[0001] The invention belongs to the technical field of sockets, and in particular relates to a two-core and three-core combined hole-free socket. Background Art
[0002] In the prior art, ordinary sockets have leaky holes, which not only causes dust to enter the sockets, but more dangerously, since children's height is comparable to that of some sockets, it is easy for children to put their hands into the sockets, causing a risk of electric shock. The Chinese patent "branch-conductor holeless socket" (patent number: 2013100924518) solves the above problems well, and branch-conductor holeless sockets are also accepted and used by everyone.
[0003] However, with the continuous improvement of people's quality of life, the country has proposed that sockets should have the function of preventing single pressure. Because in the prior art, when a pin on the plug is inserted into the socket alone, it is easy to cause the fixed conductive sheet on the side where the pin is not inserted to contact with the rotating conductive sheet, causing a short circuit in the circuit and posing a safety hazard to electricity use. Therefore, it is imperative to have a hole-less socket that prevents single pressure. However, there is no technical solution in the prior art that can solve the problem of the function of preventing single pressure in a hole-less socket. Summary of the invention

[0022] 1. The pin of the three-core plug is inserted into the three-core plug hole 5 to drive the three-core protection door 38 to drive the three-core cam 39 to rotate, and the three-core cam 39 drives the three-core protection door shaft 32 to sequentially drive the three-core connecting rod 33, the three-core anti-single pressure slider connecting rod 34 and the three-core anti-single pressure slider 35 to move toward the side of the three-core fixed conductive sheet 37, so that the three-core sliding conductive sheet set on the concave surface of the three-core anti-single pressure slider 35 presses the three-core fixed conductive sheet 37, and the circuit of the three-core holeless socket is turned on;

[0025] The pin is inserted into the pin hole to drive the protection door to drive the cam to rotate.
