Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of switches and sockets, and in particular relates to a novel ultra-thin wall switch and socket structure which can prevent wires from loosening. Background Art
[0002] When installing switches and sockets, electricians often use wires of different specifications to connect the switches and sockets. The wire specifications used in different environments or regions are different, including multi-strand wires and single-strand wires. The commonly used wire diameters are 0.5-6mm. 2 Varies in between.
[0003] When using thinner wires, the screws are often tightened to the limit and the wires are still not firm and easy to loosen. After power is turned on, there will be power failure, short circuit, poor contact and other phenomena, which affects the normal use of the user. In more serious cases, the switch socket will burn out and a fire will occur. Utility Model Content
[0004] The technical problems to be solved by this utility model are:
[0005] The existing switches / sockets on the market generally use multi-strand or single-strand wires to connect to the power supply during the electrical installation process. The wire diameter used is 0.5-6mm. 2 Small wire diameters are very easy to loosen, resulting in poor contact of installed switches and sockets, and inability to achieve normal disconnection and use. During long-term use, the switch / socket will fail to power on, the temperature will rise, and the circuit will be burned; in severe cases, household appliances will be burned, and fires and other hidden dangers will occur.
[0006] In order to solve the above technical problems, the technical solution proposed by the utility model is: a new type of ultra-thin wall switch socket structure that prevents wires from loosening, including a panel, a pressure plate, a two-plug protection door assembly, a three-plug protection door assembly, a two-three-plug N-pole socket assembly, a two-three-plug E-pole socket assembly, a two-three-plug L-pole socket assembly and a mounting bracket. The two-three-plug N-pole socket assembly, the two-three-plug E-pole socket assembly and the two-three-plug L-pole socket assembly respectively include a terminal group and a socket, the terminal group is clamped on the socket, the terminal group includes a screw and a terminal, the screw is threadedly connected to the terminal, the bottom of the terminal is provided with a terminal bulge, the socket is provided with a connecting piece, and the connecting piece is provided with two groups of connecting piece bulges.
[0007] In order to facilitate the limiting of the wires, the connecting piece bulges are symmetrically arranged with respect to the terminal bulges, and an inward anti-slip groove for accommodating the terminal bulges is provided between the two groups of connecting piece bulges. The protruding directions of the connecting piece bulges and the terminal bulges are arranged relative to each other.
[0008] In order to achieve the conductive effect, the connecting piece is arranged between the screw and the terminal.
[0009] Furthermore, the two-three-pin N-pole socket assembly is clamped on one side of the mounting bracket, and the two-three-pin N-pole socket assembly includes a terminal group and a N-pole socket.
[0010] Furthermore, the two-three-pin L-pole socket assembly is clamped on a side of the mounting bracket away from the two-three-pin N-pole socket assembly, and the two-three-pin L-pole socket assembly includes a terminal group and an L-pole socket.
[0011] Furthermore, the two-three-pin E-pole socket assembly is clamped in the mounting bracket and arranged between the two-three-pin N-pole socket assembly and the two-three-pin L-pole socket assembly, and the two-three-pin E-pole socket assembly includes a terminal group and an E-pole socket.
[0012] Furthermore, the two-insert protection door assembly and the three-insert protection door assembly are movably arranged on the upper side of the socket, and are movably connected through a spring and a pressure plate clamped on the mounting bracket to perform limiting and shielding.
[0013] For aesthetic reasons, the panel card is arranged on the upper side of the mounting bracket.
[0014] The beneficial effects achieved by the utility model using the above structure are as follows:
[0015] A convex bump is made on the inner side of the terminal, two convex bumps are made on the side of the connecting piece close to the terminal, and an inward-concave anti-slip groove is made on the flat surface of the connecting piece close to the convex bump. This allows the two convex bumps of the terminal and the connecting piece to move closer together when the screws are tightened during the wiring process, which can lock the wires firmly and prevent them from loosening. This structure is particularly effective for multi-strand and single-strand wires with small diameters. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figure 1-6 As shown, the utility model proposes a novel ultra-thin wall switch socket structure for preventing loose wires, taking a two- or three-pole socket as an example: it is composed of a panel 1, a pressure plate 2, a two-prong protection door assembly 3, a three-prong protection door assembly 4, a two- or three-prong N-pole socket sleeve assembly 5, a two- or three-prong E-pole socket sleeve assembly 6, a two- or three-prong L-pole socket sleeve assembly 7, and a mounting bracket 8.
[0026] The two-three-pin N-pole socket assembly 5, the two-three-pin E-pole socket assembly 6, and the two-three-pin L-pole socket assembly 7 respectively include a terminal group and a socket. The terminal group is clamped on the socket. The terminal group includes a screw 201 and a terminal 202. The screw 201 is threadedly connected to the terminal 202. The bottom of the terminal 202 is provided with a terminal convex bump 301. The socket is provided with a connecting piece, and the connecting piece is provided with two groups of connecting piece convex bumps 302.
[0027] In order to facilitate the limiting of the wires, the connecting piece bulges 302 are symmetrically arranged with respect to the terminal bulges 301, and an inward anti-slip groove for accommodating the terminal bulges 301 is provided between the two groups of connecting piece bulges 302, and the protruding directions of the connecting piece bulges 302 and the terminal bulges 301 are arranged relative to each other.
[0028] In order to achieve the conductive effect, the connecting piece is provided between the screw 201 and the terminal 202 .
[0029] Screw the screw 21 into the terminal 22 and install it on the N-pole socket 23, L-pole socket 24, and E-pole socket 25 respectively.
