Description

Technical Field

[0001] The invention belongs to the technical field of electric power, relates to indoor electric power equipment, and specifically relates to a wiring-free socket. Background Art

[0002] Sockets need to be installed during house construction and decoration. When installing sockets, the wires need to be routed to a junction box and then branched from this junction box to the next one or more junction boxes. Each junction box has three types of wires, namely the live wire (L), the neutral wire (N), and the ground wire. In the junction box, multiple wires of the same type need to be connected together and one wire needs to be led out to connect to the socket panel.

[0003] The traditional practice is to first route the wires to a junction box and then branch them from this junction box to the next one or more junction boxes. When wiring, first strip the insulation layer of the wires, then twist the conductors of multiple wires of the same type together to make a joint to lead out a wire, then wrap the joint with insulating tape, and then connect the lead-out wire to the socket panel.

[0004] The traditional method has the following disadvantages: when there are many wires in the same junction box, it is difficult to accommodate too many wires due to the limited space of the junction box, and then connect the lead wires to the socket panel, making it difficult to install the socket panel; the socket panel must be wired when installed, and the conventional method of the connector on the back of the socket panel makes it difficult to route the wires.

DETAILED DESCRIPTION

[0038] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0039] like Figures 1 to 6 As shown, the wiring-free socket of the present invention comprises a socket panel and a junction box, wherein the socket panel comprises a socket panel 241 having a group of three-phase sockets and two-phase sockets, a panel base 243 having a three-phase connector, and a conductive socket assembly 242 installed between the socket panel and the panel base;

[0040] The conductive socket assembly includes a left bridge plate 244, a right bridge plate 245 made of conductive material, and a middle bridge plate 246 installed between the left and right bridge plates;

[0041] The left bridge plate comprises a first jack clip 31, a second jack clip 32 and a connecting arm 33 connecting the two, and the back of the connecting arm has a first conductive head 37; the right bridge plate comprises a third jack clip 34, a fourth jack clip 35 and a connecting arm 33 connecting the two, and the back of the connecting arm has a second conductive head 38; the middle bridge plate comprises a fifth jack clip 36 and a third conductive head 39 located at the back of the fifth jack clip;

[0042] The positions of the three conductive heads correspond to the positions of the three-phase connectors on the panel base.

[0043] The present invention is mainly applied to the layout structure in which the three-phase connectors in the junction box are distributed diagonally. Correspondingly, the three-phase connectors on the panel base are usually also located on a diagonal line. If the three-phase connectors of the junction box are distributed in other shapes, the three-phase connectors on the panel base also correspond to the positions of the three-phase connectors.

[0044] like Figure 1 As shown, a common socket panel is provided with a two-phase socket, and a three-phase socket is provided below the two-phase socket. The three-phase sockets correspond to the live wire, the neutral wire and the ground wire respectively, and the two-phase socket corresponds to the live wire and the neutral wire. For this purpose, a left bridge board is used to connect the live wires of the three-phase socket and the two-phase socket, the first socket clip and the second socket clip are respectively inserted into the live wire holes of the three-phase socket and the two-phase socket, the right bridge board connects the neutral wires of the three-phase socket and the two-phase socket, the third socket clip and the fourth socket clip are respectively inserted into the neutral wire holes of the three-phase socket and the two-phase socket, the fifth socket clip on the middle bridge board is inserted into the ground wire hole of the three-phase socket, the left bridge board, the right bridge board and the middle bridge board installed between the left and right bridge boards are respectively fixed in the insulating support grids of the panel base, and the conductive heads on the back of the left bridge board, the right bridge board and the middle bridge board are inserted into the three-phase connector on the panel base.

[0045] The jack clip is usually formed by a pair of metal spring veneers, and the metal springs are both connected to the connecting arms.

[0046] Figures 1 to 8 In the specific embodiment shown, the panel base has three cylindrical insulating sockets on the side facing the conductive socket assembly, and the cylindrical insulating sockets are respectively connected to the three-phase connectors. The panel base is provided with an insulating support grid 40 on the side facing the conductive socket assembly to support the conductive socket assembly. The conductive head is usually a banana plug, which is convenient for inserting into the socket.

[0047] like Figure 1 and Figure 8 As shown, the socket panel of the present invention is mainly used as a part of the socket and can be used with Figure 6 and Figure 8 The junction box shown is used to connect and splice wires to sockets. The wires enter and exit from the wire inlet and outlet holes 12. The wires need to be physically fixed and electrically connected to the connector in the junction box, and electrically connected to the three-phase connector of the socket through the connector.

[0048] The connector comprises an insulating upper cover 4, an insulating shell 2 and a conductive connecting member 3; the insulating upper cover 4 and the insulating shell 2 are connected vertically and wrap the conductive connecting member 3;

[0049] The conductive connector 3 includes a cover plate 8, a wire post 7 above the cover plate 8, and more than one pair of stripping plates 9 below the cover plate 8; a wire insertion slot is provided at the bottom of the stripping plate 9, and the wire insertion slot is composed of a wire fixing slot 17 and a cutting slot 18 located below the wire fixing slot 17 and connected to the opening of the wire insertion slot, and the edge of the cutting slot 18 has a knife edge, and the width of the cutting slot 18 is continuously reduced and is greater than the width of the wire fixing slot 17; the heights of the wire insertion slots on each pair of stripping plates 9 are different; the position and height of the wire insertion slots correspond to the position and height of the first lower groove 19;

[0050] The insulating upper cover 4 has a wire post through hole 5 and a snap-fit ​​mechanism that cooperates with the insulating housing 2 .

[0051] like Figure 1 and Figure 6 , Figure 8 As shown, the junction box of the present invention is mainly used as a part of the socket. When the wires are connected and spliced ​​with the socket, the wires enter and are led out from the wire entry and exit holes 12. The wires need to be physically fixed and electrically connected to the connector in the junction box, and electrically connected to the three-phase connector of the socket through the connector.

[0052] Taking the commonly used three-phase AC wires as an example, the junction box needs to connect three different wires, namely the live wire, the neutral wire and the ground wire. The junction box needs three connectors to connect the live wire, the neutral wire and the ground wire respectively; the insulating shell 2 on the connector is fixed to the bottom of the connection box. In the specific implementation shown in the figure, the insulating shell 2 and the conductive connector 3 respectively have two pairs of first lower grooves 19 and a stripping plate 9. The wires are inserted into a pair of first lower grooves 19 of the insulating shell 2, or two wires can be inserted into the two pairs of first lower grooves 19 respectively. The arrangement axis of the two pairs of first lower grooves 19 is preferably arranged in a vertical cross shape, which is convenient for routing wires from each inlet and outlet hole 12 on the side wall of the junction box.

[0053] To facilitate wiring, the connector and the fixed base 11 at the bottom of the junction box can be distributed on a diagonal line of the rectangular junction box, so that the projection positions on the two pairs of side walls are different, and the wiring can be run in parallel and gathered at the inlet and outlet holes 12.

[0054] After the wire is inserted into the first lower groove 19, the wire insertion slot opening on the stripping plate 9 of the conductive connector 3 is aligned with the first lower groove 19 and inserted. The insulating sheath outside the wire is first cut by the gradually shrinking cutting groove 18, and finally, after the sheath is completely stripped, it is inserted into the narrower wire fixing groove 17. The width of the wire fixing groove 17 is determined according to the inner core diameter of the standard indoor wire. After the insulating sheath is stripped, the wire is fixed and pressed by the stripping plate 9 and the first lower groove 19, and the wire and the conductive connector 3 are fixed and electrically connected at the same time. The use of a pair of cutting grooves 18 to cut the wire at the same time has a higher reliability of the electrical connection.

[0055] After the conductive connector 3 fixes the wire, the insulating upper cover 4 is put on to press the conductive connector 3 tightly to insulate the outside of the conductive connector 3, and the wire post on the top of the conductive connector 3 is inserted into the wire post through hole 5 on the insulating upper cover 4.

[0056] The conductive connector 3 is made of a conductive material such as a metal plate as a whole, and is connected to the wire post through hole 5 through the wire post above the conductive connector 3, and extends from the wire post through hole 5 as a connection point between the connector and the socket.

[0057] The conductive connector 3 and the insulating upper cover 4 can be fixedly connected by using an in-mold injection molding process during the production process, thereby reducing the number of installation steps.

[0058] The first lower groove 19 of the insulating housing 2 has card slots 21 on both sides thereof that cooperate with the stripping plate 9 .

[0059] In the specific implementation as shown in the figure, two pairs of upper and lower layers are used to place the wires in a cross shape, and the wires can enter and exit from two pairs of inlet and outlet holes 12 on the side wall of the box.

[0060] If the wires only need to enter and exit from one side, they can be cut or tied in a knot inside the box. Fig.14 As shown, one or more leads can be arbitrarily selected from the four directions of the cross-shaped distribution of the upper and lower layers.

[0061] Figures 10 to 13 In the specific embodiment shown, the insulating cover 4 and the insulating housing 2 are both cylindrical, and the engaging mechanism is a first clamping hole 6 and a first clamping buckle 20 that cooperate with each other and are arranged on the outer walls of the insulating cover 4 and the insulating housing 2. The number of the first clamping hole 6 and the first clamping buckle 20 can be 1 pair or 2 pairs.

[0062] Fig.10 and Fig.13 In the specific embodiment shown, the first lower groove 19 of the insulating shell 2 has card slots 21 on both sides that cooperate with the stripping plate 9. The stripping plate 9 can be inserted into the card slots 21 on both sides to better fix the conductive connector 3 to the insulating shell 2.

[0063] Fig.15 and Fig.16 In the specific embodiment shown, a preferred embodiment of fixing the connector to the bottom surface of the junction box is provided, and a fixing base 11 is provided on the bottom surface of the junction box, and the inner diameter of the outer wall of the fixing base 11 is gap-matched with the inner wall of the bottom of the insulating housing 2, and the outer wall of the fixing base 11 has a second lower groove 15 that is highly matched with the position of the first lower groove 19 on the insulating housing 2;

[0064] The bottom of the fixed base 11 has more than three support plates and a plurality of second buckles 14 , and the bottom surface of the insulating shell 2 has second buckle holes 22 that cooperate with the second buckles 14 .

[0065] Insert the lower side of the insulating housing 2 of the connector into the fixed base 11, and insert the second clip 14 into the second clip hole 22. The second clip 14 is a plastic component with a certain flexibility. After being squeezed and deformed, it can be inserted into the second clip hole 22 and restored. The connector is supported on the fixed base 11 by multiple support plates, and the wire extending from the first lower groove 19 of the connector extends out through the second lower groove 15.

[0066] Taking the commonly used three-phase AC wire as an example, the junction box needs to connect three different wires, namely the live wire, the neutral wire and the ground wire. The junction box needs three connectors to connect the live wire, the neutral wire and the ground wire respectively; for the convenience of wiring, the connector and the fixed base 11 at the bottom of the junction box can be distributed on a diagonal line of the rectangular junction box 1, so that the projection positions on the two pairs of side walls are different, and the wiring can be run in parallel and gathered at the wire inlet and outlet holes 12.

[0067] The junction box of the present invention is a part of the socket, and the installation of the socket containing the junction box of the present invention is the same as the installation of the traditional socket. Figures 6 to 9 As shown, after the wires are installed, the junction box 1 is fixed in the installation groove of the wall, and the panel 24 with the jack is covered. The plug 26 on the back of the panel is inserted into the wire post through hole 5 at the top of the connector on the junction box to be electrically connected and fixed with the conductive connector in the connector; and the bolt 25 is screwed into the screw hole on the junction box and the jack panel, and then the decorative cover 23 is covered to form a complete socket.

[0068] like Figures 1 to 6 As shown, a common socket panel is provided with a two-phase socket, and a three-phase socket is provided below the two-phase socket. The three-phase sockets correspond to the live wire, the neutral wire and the ground wire respectively, and the two-phase socket corresponds to the live wire and the neutral wire. For this purpose, a left bridge board is used to connect the live wires of the three-phase socket and the two-phase socket, the first socket clip and the second socket clip are respectively inserted into the live wire holes of the three-phase socket and the two-phase socket, the right bridge board connects the neutral wires of the three-phase socket and the two-phase socket, the third socket clip and the fourth socket clip are respectively inserted into the neutral wire holes of the three-phase socket and the two-phase socket, the fifth socket clip on the middle bridge board is inserted into the ground wire hole of the three-phase socket, the left bridge board, the right bridge board and the middle bridge board installed between the left and right bridge boards are respectively fixed in the insulating support grids of the panel base, and the conductive heads on the back of the left bridge board, the right bridge board and the middle bridge board are inserted into the three-phase connector on the panel base.

[0069] Figures 1 to 7 In the specific embodiment shown, the panel base has three cylindrical insulating sockets on the side facing the conductive socket assembly, and the cylindrical insulating sockets are respectively connected to the three-phase connectors. The panel base is provided with an insulating support grid 40 on the side facing the conductive socket assembly to support the conductive socket assembly. The conductive head is usually a banana plug, which is convenient for inserting into the socket.

[0070] By adopting the socket of the present invention, the wires to be connected can be placed in layers by setting an insulating upper cover, an insulating shell, and a conductive connector, and the connection and fixation of the wires and the electrical connection can be achieved through simple operations when installing the wires, and the wires can be led out in multiple directions of the upper and lower layers, which is convenient for overall layout and wiring, and the wire connection and branching operations are simple, and the socket panel does not need to be wired. The operation process of the present invention is simple and fast, the wire conductors will not be exposed, and it is safe to use.

[0071] The foregoing describes various preferred embodiments of the present invention. Unless the preferred implementation modes in various preferred embodiments are obviously self-contradictory or based on a certain preferred implementation mode, various preferred implementation modes can be arbitrarily superimposed and used in combination. The embodiments and specific parameters in the embodiments are only for clearly describing the invention verification process of the inventor, and are not used to limit the patent protection scope of the present invention.
