Description

Technical Field

[0001] The present invention relates to the technical field of electrical devices, and in particular to an elastic support device, a safety protection structure, a power distribution system and a power supply method. Background Art

[0002] The power distribution system is generally used in residential homes or commercial buildings. Its main structure is a track-type plug-in bridge-type electrical channel. Usually, the track-type plug-in bridge-type electrical channel is fixed on the wall surface, and then the electrical connector is directly inserted into the power supply slot of the electrical channel to achieve the purpose of the electrical connector drawing power from the electrical channel. Among them, the power supply slot in the most common power distribution system is provided with a live wire power supply terminal, a neutral wire contact terminal, and a ground wire contact terminal; when the electrical connector is inserted into the power supply slot of the electrical channel, one contact of the electrical connector contacts the live wire power supply terminal, and the other contact of the electrical connector contacts the neutral wire contact terminal, thereby achieving the purpose of electrical appliance drawing power, wherein the ground wire contact terminal is grounded to protect the electrical connector.

[0003] Since the main structure of the above-mentioned power distribution system (i.e., the track-type plug-in bridge electrical channel) is installed on the wall, foreign objects such as dust particles and debris in the external environment often fall into the power supply slot, causing the foreign objects to directly contact the conductor inside the power supply slot (i.e., the live wire power supply terminal or the neutral wire power supply terminal), so that a certain current is present on the foreign object body. At this time, when the power supply terminal of the electrical connector is close to the conductor of the power supply slot but has not yet touched it, that is, the power supply terminal has not yet been inserted into place, the electrical connector will be energized.

[0004] During the above operation, the human body is required to manually plug the electrical connector directly into the track-type plug-in bridge electrical channel. Therefore, when the electrical connector is not plugged into place and power is directly turned on, the human body can easily accidentally touch the exposed contact end of the electrical connector, causing electric shock to the human body, which lacks safety. Summary of the invention

[0005] In order to solve the above technical problems, the purpose of the present invention is to provide a power distribution system with a safety protection structure, which can prevent foreign objects from falling into the power distribution system and directly contacting the conductors, thereby effectively increasing the safety of electricity use.

[0006] In a first aspect, the present invention provides an elastic support device. The elastic support device comprises a fixed end and a movable end; one end of the movable end is fixed to the fixed end, and the other end is bent and forms an angle with the fixed end; a contact piece is arranged on the movable end, and the contact piece is fixedly connected to the movable end.

[0007] In a second aspect, the present invention provides a safety protection structure. The safety protection structure includes an insulating support device, a conductor, and the above-mentioned elastic support device. The conductor is fixed on the insulating support device; the fixed end is fixed on the insulating support device; a gap is reserved between the movable end and the conductor, and the conductor and the fixed end are respectively arranged on adjacent surfaces of the insulating support device; at least one elastic support device is arranged in sequence along the length direction of the conductor; and a plurality of elastic reinforcement holes are arranged on the surface of the conductor.

[0008] In a third aspect, the present invention provides a power distribution system, comprising a housing with a plug interface and the above-mentioned safety protection structure. The housing is provided with a power extraction slot located below the plug interface; the safety protection structure is fixed in the power extraction slot, and the movable end is located below the plug interface.

[0009] In a fourth aspect, the present invention provides a method for obtaining power, using the power distribution system described above, comprising the following steps:

[0010] a) Fix the housing of the rail-type plug-in bridge electrical channel directly to the plane;

[0011] b) Connecting the conductor to the power supply through the power cord;

[0012] c) Insert the contacts of the electrical connector into the power supply slot through the plug interface. When the roots of the contacts of the electrical connector come into contact with the outside of the shell, the elastic support device comes into contact with the conductor, and the contacts of the electrical connector are energized.

[0013] The beneficial effects of the present invention are:

[0014] (1) Through the present invention, an elastic support device is provided in the power supply slot of the track-type plug-in bridge-type electrical channel. When the electrical connector is plugged in to draw power, the elastic support device is in direct contact with the conductor to achieve power supply; when the electrical connector is removed from the power supply slot, the elastic support device returns to its original position and is separated from the conductor. Through the present invention, the elastic support device is used as an intermediate transition connection section in a segmented power supply method, thereby preventing foreign objects from falling into the power distribution system and directly contacting the conductor, thereby effectively increasing the safety of electricity use.

[0015] (2) Through the present invention, a contact spring is arranged on the side of the movable end of the elastic support device facing the conductor, so that contact between the contact spring and the conductor can be achieved. When the electrical connector is plugged in, the contact spring is pressed inward and directly contacts the conductor. When the electrical connector is not plugged in, a gap exists between the contact spring and the conductor due to the elastic restoring force, so that the electrical connector is prevented from being directly powered when it is not plugged in, thereby further improving the safety of electricity use. The contact spring is integrally formed with the movable end and is bent facing the conductor. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Power supply slots 2 are symmetrically arranged at both ends of the shell 1, and the power supply slots 2 are located below the plug interface 11. When the live wire connector and the neutral wire connector of the electrical connector are respectively inserted into the shell 1, the live wire connector and the neutral wire connector are respectively plugged into the corresponding power supply slots 2; end covers 12 are fixedly connected to both sides of the shell 1 to prevent dust from entering the inside of the shell 1.

[0037] like Figure 2As shown, the bottom of the inner wall of the power taking slot 2 on one side of the housing 1 is provided with a fixing protrusion 24, and an insulating support device 7 is directly fixedly connected to the fixing protrusion 24, and a clamping groove 73 is provided at the bottom of the insulating support device 7 at a position corresponding to the fixing protrusion 24, wherein the fixing protrusion 24 is embedded in the clamping groove 73, thereby achieving the purpose of fixing the insulating support device 7. A longitudinal support column 71 is longitudinally provided on the insulating support device 7, and a conductor 3 is clamped on the outer surface of the longitudinal support column 71, wherein the conductor 3 is divided into a live conductor and a neutral conductor, which correspond to the above-mentioned live connector and neutral connector one by one, that is, the live conductor corresponds to the live connector, and the neutral conductor corresponds to the neutral connector;

[0038] A longitudinal clamping column 72 is provided on one side of the insulating support device 7 adjacent to the longitudinal support column 71. Fig.15 An elastic support device 4, wherein one end of the elastic support device 4 is a movable end 41, and a gap is reserved between it and the conductor 3. When the electrical connector is plugged in place, the movable end 41 contacts the conductor 3; the other end of the elastic support device 4 is a fixed end 42, wherein one end of the movable end 41 is embedded in the fixed end 42, and the other end is directly suspended in the power extraction slot 2, and forms an obtuse angle or a right angle with the fixed end 42; and a clamping column 21 is provided inside the power extraction slot 2, and the fixed end 42 of the elastic support device 4 is provided with a groove, and the groove is fixed on the clamping column 21, so that the elastic support device 4 is fixed as a whole in the power extraction slot 2;

[0039] An arc-shaped protrusion 23 is provided at the bottom of the power-taking slot 2 adjacent to the fixed protrusion 24, and a grounding assembly 8 is directly clamped on the arc-shaped protrusion 23, and the grounding assembly 8 includes a ground conductor 81 fixed on the arc-shaped protrusion 23 and a ground insulator 82 crimped on the ground conductor 81. Among them, the inner wall of the power-taking slot 2 and the bent and raised ground conductor 81 form a limiting space 83, and the ground insulator 82 is directly sleeved in the limiting space 83. When a high-power electrical connector is connected to the system, the grounding assembly 8 can provide grounding protection for it.

[0040] Among them, reference Figure 6 An arc-shaped clamping protrusion is provided at the bottom of the ground conductor 81, and a corresponding arc-shaped clamping groove is provided on the ground insulator 82. The arc-shaped clamping groove is embedded in the arc-shaped clamping protrusion to realize the clamping of the ground conductor 81 and the ground insulator 82, and the ground insulator 82 provides good support for the ground conductor 81.

[0041] An accommodating groove 22 is provided at the opposite end of the power taking slot 2 to the elastic supporting device 4, and a rubber strip 6 made of rubber material is clamped in the accommodating groove 22. The rubber strip 6 is located below the plug interface 11 and fits each other, and one end of the rubber strip 6 extends horizontally to cover the plug interface 11. The extended end of the rubber strip 6 can directly block dust to the outside of the housing 1, thereby preventing dust from entering the power taking slot 2 and affecting the safety of power taking.

[0042] refer to Figure 1 and Figure 8 A limit strip 9 is directly crimped on the inner side of the grounding component 8, and the two relatively arranged limit strips 9 are simultaneously compressed and connected by a transverse pressure plate 10, wherein the limit strip 9 plays a role of compressing and limiting the grounding component 8, thereby preventing the grounding component 8 from being directly overlapped with the shell 1, thereby improving the safety of electricity use; at the same time, a card box 13 is directly arranged on the upper end of the limit strip 9 and the transverse pressure plate 10, which prevents dust from entering and affecting the grounding safety.

[0043] Example 2

[0044] Based on Example 1, Figure 3 , a contact piece 5 is provided on the side of the movable end 41 facing the conductor 3, the contact piece 5 is integrally formed with the movable end 41, and is bent toward the conductor 3, forming an acute angle with the movable end. A contact piece 5 is integrally bent toward the conductor 3 on the movable end of the elastic support device 4, so as to achieve contact between the contact piece 5 and the conductor 3; wherein, a hollow portion 411 is provided at the bending position, one end of the contact piece 5 is separated from the hollow portion 411, and the other end of the contact piece 5 is directly bent on the conductor 3; when the electrical connector is plugged in, the contact piece 5 is pressed inwardly and directly contacts the conductor 3, and when the electrical connector is not plugged in, under the action of the elastic restoring force, there is a gap between the contact piece 5 and the conductor 3, so as to avoid the electrical connector being directly powered when it is not plugged in, thereby further improving the safety of electricity use; wherein, the contact piece 5 is integrally formed with the movable end, and is bent toward the conductor 3.

[0045] Example 3

[0046] Based on Example 2, Figure 3 A T-shaped hole 412 is provided adjacent to the bend of the contact member 5, which can dissipate the heat on the elastic support device 4 as quickly as possible to prevent the elastic support device 4 from overheating and affecting the stability of the circuit connection. In this embodiment, the contact member 5 is a contact spring.

[0047] Example 4

[0048] Based on Example 3, Figure 4 A plurality of elastic support devices 4 are fixed in sequence along the length direction of the conductor 3. When one of the elastic support devices 4 fails, it can be directly replaced from the power extraction slot 2 without having to replace the entire device, thereby reducing the replacement cost.

[0049] Example 5

[0050] Based on Example 1, Figure 5A plurality of elastic reinforcement holes 31 are provided on the surface of the conductor 3. When the temperature rises instantly during the power-drawing process, the elastic reinforcement holes 31 provide the conductor 3 with sufficient elastic deformation capability, thereby improving the overall ductility.

[0051] Example 6

[0052] Based on Example 1, Figure 7 The surface of the rubber strip 6 is provided with wavy folds 61. When the electrical connector is inserted into the device, the folds reduce the friction with the contact head of the electrical connector, thereby reducing the loss of the rubber strip 6 and enabling the electrical connector to be smoothly inserted into the corresponding power supply slot 2.

[0053] Example 6

[0054] refer to Fig. 9 The difference from Example 1 is that the bottom of the fixed end 42 of the elastic support device 4 and the longitudinal clamping column 72 of the insulating support device 7 are designed to be an integrally formed structure, that is, the overall fixed end 42 includes the longitudinal clamping column 72, thereby improving the overall integrity of the elastic support device 4 and facilitating production and installation.

[0055] Example 7

[0056] refer to Fig.10 , which is different from the embodiment 2, in this embodiment, the movable end 41 is not provided with a contact piece 5, but a groove 413 is provided on the surface of the movable end 41. When the tail of the contact of the electrical connector contacts the outer side of the shell, the outer surface protrusion of the groove 413 on the surface of the movable end 41 on the elastic support device 4 contacts the conductor 3, and the electrical connector contact is powered. The power supply method is direct and the response is sensitive. Stretching plate

[0057] Example 8

[0058] refer to Fig.11 The difference from Example 2 is that in this embodiment, no contact piece is provided in the movable end 41, but the movable end 41 is directly bent. When the tail of the contact of the electrical connector contacts the outside of the shell, the bent inclined surface of the movable end 41 located on the elastic support device 4 contacts the conductor 3, and the electrical connector contact is energized.

[0059] Example 9

[0060] refer to Fig.12 and Fig.13, which is different from Embodiment 2 in that the contact piece 5 in the movable end 41 of this embodiment is a convex block protruding toward the conductor 3, and a concave depression is provided at the corresponding position on the conductor 3; when the electrical connector is inserted into the housing 1, the terminal of the electrical connector gradually contacts the movable end 41 of the elastic support device 4, and when the terminal of the electrical connector is fully extended into the power extraction slot 2, the convex block of the contact piece 5 on the elastic support device 4 will sink into the concave depression of the conductor 3, thereby connecting the conductor 3 with the elastic support device 4 and the electrical connector. In this embodiment, the contact piece 5 composed of the convex block is integrally formed with the movable end 41, thereby increasing the strength and integrity of the movable end 41.

[0061] Example 10

[0062] refer to Fig.14 On the basis of the fifth embodiment, a plurality of T-shaped holes 412 are provided on the movable end 41 at a position adjacent to the contact member 5 , and their functions are the same as those of the third embodiment.

[0063] In the present invention, Figure 1-15 As shown, a method for obtaining electricity includes the following steps:

[0064] a) Fix the housing of the rail-type plug-in bridge electrical channel directly to the plane;

[0065] Among them, the fixing method can be a variety of detachable fixing connections such as clamping plate clamping, bolt fixing connection, glue bonding, etc., that is, the track-type plug-in bridge-type electrical channel can be removed from the wall, which is convenient for use in multiple scenarios;

[0066] When step a is completed, proceed to step b:

[0067] b) Connecting the conductor to the power supply through the power cord;

[0068] This method generally involves directly connecting a power line at one end of the conductor, and then connecting the power line to the power source, wherein the live conductor is connected to the live wire, and the neutral conductor is connected to the neutral wire;

[0069] When step b is completed, proceed to step c:

[0070] c) Insert the contacts of the electrical connector into the power supply slot through the plug interface. When the tail of the contacts of the electrical connector contacts the outside of the shell, the elastic support device contacts the conductor, and the contacts of the electrical connector are energized.

[0071] Among them, plane refers to various common planes such as wall, tabletop, cabinet plane, box plane, etc.

[0072] The fixed connection referred to in the present invention may be a detachable fixed connection, that is, various detachable fixed connection methods such as a snap connection, a nested connection, a bolt connection, a sliding buckle connection, etc.

[0073] Due to the structure of the present invention, when the contact root of the electrical connector, i.e. the edge of the insulating material of the electrical connector, contacts the outer side of the shell, the elastic support device contacts the conductor and the electrical connector contact is energized, which means that the electrical connector is plugged in place.

[0074] 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.
