Description

Technical Field

[0001] The invention relates to a novel power connector, belonging to the technical field of electrical devices. Background Art

[0002] The electric track type power distribution device currently used in residential and commercial buildings consists of an electric track and an electric connector. The electric track is a single cavity with a single opening for power extraction. The electric track is electrically connected to a socket already provided on the wall through a long conductor arranged in its cavity, and can be extended to a suitable power extraction point by being installed along the wall. The electric connector can be inserted into the power extraction slot. After the electric connector is inserted into the power extraction slot at any position along the electric track, it is rotated to connect the circuit and realize a conductive connection.

[0003] The existing electrical connector includes an upper socket and a lower base. The upper socket can rotate relative to the lower base. The upper socket is provided with a conductive connector electrically connected to the conductor in the power track. The conductive connector is separated from the conductor before the upper socket rotates, that is, the circuit remains in an off state. After the upper socket rotates, the conductive connector is in a contact state with the conductor, that is, the circuit remains in an on state.

[0004] However, when the conductive connector on the electrical connector is rotated by the upper socket, it will directly contact the conductor. This method of directly contacting the conductor by horizontally rotating the conductive connector is prone to safety accidents. Even if a protective rubber strip is installed, it is difficult to overcome the safety hazard caused by the conductive connector on the power connector directly touching the conductor over the rubber strip. Summary of the invention

[0005] In order to solve the above technical problems, the purpose of the present invention is to provide a new type of power connector, which can prevent the conductive connecting parts of the power connector from directly contacting the conductor after entering the power extraction slot, thereby avoiding potential safety hazards in electricity use.

[0010] As a preferred example, the power connector also includes a rotation limit plate, which is rotatably connected to the lower base, and an auxiliary rotation column is provided on the rotation limit plate to push the rotating member to realize rotation, and the auxiliary rotation column is arranged on both sides of the toggle shaft.

[0011] As a preferred example, the rotating toggle mechanism also includes a rotating shaft and a connecting member, one end of the rotating shaft is connected to the connecting member, rotating members are hinged on both sides of the connecting member, a slot for a limiting block is provided on the rotating member, and the block flips inside the slot.

[0012] As a preferred example, an arc-shaped limiting groove is provided on the rotating limiting plate, and a limiting column is provided on the top of the lower base, and the limiting column is located in the arc-shaped limiting groove.

[0015] The beneficial effects of the present invention are:

[0016] (1) According to the present invention, the electrical connector includes a conductive connector, which is composed of a toggle shaft that can rotate around an axis and a toggle plate provided on the toggle shaft.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations and embodiments.

[0031] Example:

[0032] like Figure 1 As shown, an embodiment of the present invention provides a novel power rail type power distribution device, which includes a power rail 1 and an electric connector 2. The power rail 1 is used to access the three-phase mains power, and the electric connector 2 is used to connect an external power-consuming device to the power rail 1, and then to the three-phase mains power. The electric connector 2 is arranged between two power rails 1, and the electric connector 2 can move between the power rails 1. The electric connector 2 on the power rail 1 is not limited to one. Figure 1 In the illustrated embodiment, the same end of the two power rails 1 is commonly connected to a connection terminal 3 , and the power rails 1 are connected to three-phase electricity via the connection terminal 3 .

[0033] like Figure 2 As shown, the two power rails 1 include two rail housings 10, two insulators 11 and four conductors. The two rail housings 10 are arranged in parallel, and a first cavity 14 is provided inside the rail housing 10. First openings 15 are provided on opposite sides of the rail housing 10. Two insulators 11 are respectively installed in the first cavity 14 of each rail housing 10. According to the nature of the conductor, the conductor provided in one insulator 11 is a live conductor, and the conductor provided in the other insulator 11 is a neutral conductor. The insulator 11 is made of insulating rubber strip material, and a second cavity 16 is provided inside the insulator 11. A second opening 17 is provided on one side of the insulator 11 located at the first opening 15, and a power extraction slot 18 is formed between the second openings 17 of the two insulators 11.

[0034] like Figure 3 As shown, a first conductor slot 110 and a second conductor slot 111 are respectively provided inside the insulator 11 on the upper and lower sides of the second cavity 16. Structurally, the conductor provided in the first conductor slot 110 is a planar conductor 12, and the bottom surface of the planar conductor 12 does not protrude to the power extraction slot 18. The conductor provided in the second conductor slot 111 is a convex conductor 13, and the middle part of the convex conductor 13 protrudes to the power extraction slot 18.

[0035] The first opening 15 and the second opening 17 are used to allow a conductive object on the electrical connector 2 to enter the insulator 11 so that the conductive object can come into contact with the conductor.

[0036] The other ends of the two power rails 1 are respectively connected to a limiting end cover 19, which limits the electrical connector 2 so that the electrical connector 2 can only move in the length direction of the power rail 1 and is connected to a semicircular connector. The semicircular connector adopts a semicircular shell 4 to fix the two power rails 1.

[0037] like Figure 4 As shown, the electrical connector 2 includes an upper socket 20 and a lower base 21, and the upper socket 20 and the lower base 21 are movably connected. Specifically, the upper socket 20 and the lower base 21 can realize coaxial rotation, wherein the lower base 21 is in a fixed state, and the upper socket 20 is in a movable state. Slots 210 are respectively provided on both sides of the shell of the lower base 21, and two power rails 1 are respectively connected to the slots 210 on both sides of the lower base 21, so that the electrical connector 2 as a whole can move along the length direction of the power rail 1. The upper socket 20 is connected to a rotary toggle mechanism 22, and the rotary toggle mechanism 22 is used to insert the power extraction slot 18.

[0038] like Figure 6 As shown, rectangular openings 211 are provided on both sides of the lower base 21 , and the rectangular openings 211 provide a movable space for the rotating toggle mechanism 22 to extend and connect to the conductor. Two column grooves 214 are provided on the bottom surface of the lower base 21 .

[0039] like Figure 7-10As shown, the rotary toggle mechanism 22 includes an intermediate shaft 220, a connecting member 221, a rotating member 222, a toggle shaft 223 and a toggle piece 224. One end of the intermediate shaft 220 is connected to the upper socket 20, and the other end is connected to the connecting member 221. The two ends of the connecting member 221 are respectively connected to the rotating member 222. One end of the toggle shaft 223 is connected to the rotating member 222, and the other end is integrally connected to the toggle piece 224. The toggle shaft 223 and the toggle piece 224 are inserted into the power-taking slot 18 through the rectangular opening 211. The rotation of the upper socket 20 drives the toggle piece 224 of the rotary toggle mechanism 22 to flip. The toggle piece 224 flips to contact or separate the conductor recessed in the power-taking slot 18. A rotating column 229 is provided at the bottom of the rotating member 222, and the rotating member 222 rotates in the column slot 214 through the rotating column 229.

[0040] Preferably, Figure 6 and Figure 7 As shown, a rotating limit plate 23 is connected to the bottom of the upper socket 20, and an arc-shaped limit groove 231 is provided on the rotating limit plate 23. A limiting column 212 is provided on the top of the lower base 21. The limiting column 212 is located in the arc-shaped limit groove 231. At the same time, a barb is provided on the limiting column 212, which can limit the rotating limit plate 23 and the upper socket 20 on the lower base 21.

[0041] Preferably, Figure 8 As shown, the rotating member 222 is provided with a slot 226, the toggle shaft 223 is provided with a block 227 with an arc-shaped slot 228, and the inner side wall of the lower base 21 is provided with a column 213 that can be engaged with the arc-shaped slot 228. When the column 213 is engaged with the arc-shaped slot 228, the toggle piece 224 contacts the conductor. The block 227 can rotate in the slot 226, and the column 213 and the arc-shaped slot 228 can be separated.

[0042] Preferably, Figure 8 As shown, a protrusion 225 for contacting the conductor is provided at the end of the toggle piece 224, and the protrusion 225 is provided on the side of the toggle piece 224 that contacts the conductor.

[0043] Preferably, Figure 7 As shown, four auxiliary rotating columns 232 are also connected to the bottom of the rotating limiting plate 23 , and each rotating member 222 is clamped between two auxiliary rotating columns 232 . The auxiliary rotating columns 232 play a role in assisting in pushing the rotating member 222 .

[0044] Preferably, Figure 5As shown, a positioning reinforcement structure for limited movement and reliable connection is provided on the contact surface between the conductor and the electrical connector 2. The positioning reinforcement structure is a concave-convex structure or a toothed structure or an open clamping structure provided on the conductor. In this embodiment, a groove 131 structure is adopted. The groove 131 cooperates with the rotating member 222 to limit the movement of the electrical connector 2 and to make the connection between the conductor and the electrical connector 2 more stable.

[0045] like Figure 1-Figure 10 As shown, the working principle of the embodiment of the present invention is as follows:

[0046] (1) When electrical appliances need to be connected to the power supply;

[0047] The electrical connector 2 is installed between the two power rails 1, the rotating member 222, the toggle shaft 223 and the toggle piece 224 are located in the power taking slot 18, the two toggle pieces 224 are deflected downward at this time, one toggle piece 224 is separated from the neutral conductor, and the other is separated from the live conductor, and at the same time, the clamping column 213 is separated from the arc groove 228, and the electrical connector 2 is in the off state at this time. When the electrical connector 2 needs to be connected to electricity, the upper socket 20 of the electrical connector 2 is manually rotated, and the upper socket 20 rotates clockwise relative to the lower base 21, and the upper socket 20 drives the rotation limit plate 23 to rotate along the direction of the arrow. The four auxiliary rotating columns 232 on the rotating limit plate 23 push the rotating member 222 to rotate in the direction of the arrow. The rotating member 222 swings in the column groove 214 through the rotating column 229 at the bottom of one end, thereby driving the upper toggle shaft 223 to swing. During the swinging process of the other end of the rotating member 222, one side of the block 227 on the toggle shaft 223 contacts the column 213 until the column 213 completely enters the arc groove 228. At this time, the toggle shaft 223 rotates, thereby driving the toggle plate 224 to flip upward, and the wave plate 224 contacts the conductor, so that the electrical connector 2 is powered. Fig. 9 As shown, the electrical connector 2 is in the on state at this time.

[0048] (2) Similarly, Fig.10 As shown, when the electrical appliances need to be powered off;

[0049] At this time, the electrical connector 2 is in the off state. When the electrical connector 2 needs to be powered, the upper socket 20 of the electrical connector 2 is manually rotated in the opposite direction. The upper socket 20 rotates counterclockwise relative to the lower base 21, and the upper socket 20 drives the rotary toggle mechanism 22 to rotate counterclockwise. Specifically, the four auxiliary rotating columns 232 on the rotating limit plate 23 push the rotating member 222 to rotate in the direction of the arrow. The rotating member 222 swings in the column groove 214 through the rotating column 229 at the bottom of one end, thereby driving the upper toggle shaft 223 to swing. During the swinging process of the other end of the rotating member 222, the clamping column 213 gradually disengages from the arc groove 228. During the disengagement process, one side of the clamping block 227 is blocked by the clamping column 213, and then an external force is applied to the clamping block 227 to flip it over. The clamping block 227 drives the toggle shaft 223 to rotate, and the toggle shaft 223 rotates, thereby driving the toggle plate 224 to flip downward, and the wave plate 224 is separated from the conductor, thereby disconnecting the electrical connector 2.

[0050] The technical solution of the present invention brings the following beneficial effects:

[0051] According to the present invention, the electrical connector includes a conductive connector, which is composed of a toggle shaft 223 that can rotate around an axis and a toggle sheet provided on the toggle shaft 223. The toggle shaft 223 can drive the toggle sheet 224 to flip, so that the conductive connector will not contact the conductor immediately when entering the power supply slot 18, thereby avoiding the conductive connector of the power connector from directly contacting the conductor after entering the power supply slot 18, thereby avoiding potential safety hazards in electricity use.

[0052] According to the present invention, a rotation limiting plate 23 is provided at the bottom of the upper socket 20, and the arc-shaped limiting groove 231 on the rotation limiting plate 23 can be limited by the limiting column 212 on the lower base 21, so that the upper socket 20 can rotate within a suitable range;

[0053] Through the present invention, a slot 226 is provided on the rotating member 222, a block with an arc groove 228 is provided on the toggle shaft 223, and an inner wall of the lower base 21 is provided with a clamping column 213 that can be clamped with the arc groove 228. On the one hand, after the arc groove 228 of the clamping block 227 is blocked by the clamping column 213, the toggle piece 224 is flipped over and contacts the conductor. On the other hand, the arc groove 228 cooperates with the clamping column 213, so that the toggle piece 224 can contact the conductor more stably, avoiding the influence of external force causing the toggle piece 224 to separate from the conductor and cause power failure, thereby increasing the safety of electricity use.

[0054] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
