Description

Technical Field

[0001] The invention belongs to the technical field of distribution boxes, and in particular relates to a comprehensive distribution box. Background Art

[0002] The integrated power distribution box, also known as the JP cabinet, is a device used to receive and distribute electricity. It is mainly used to convert high-voltage electricity into low-voltage electricity and safely distribute it to various electrical equipment. It is currently widely used in various places, such as residential areas, commercial buildings, industrial plants, etc.

[0003] Electrical devices such as circuit breakers, disconnectors, contactors, and relays are usually installed in the cabinet of the integrated distribution box. In order to realize the input and output of electricity, inlet and outlet pipes are also provided on the outside of the cabinet. The cables pass through the inlet and outlet pipes and are electrically connected to the electrical devices in the cabinet.

[0004] However, in actual use, since the existing inlet and outlet pipes do not have any structure that can hinder the movement of cables, after the cables are installed, they can be easily pulled out of the cabinet by a small external force, such as when the user pulls the cables when tidying them or when the cables are accidentally touched when using the JP cabinet. At the same time, the stability of the connection between them and the electrical device will also be affected, which may affect the subsequent use of the JP cabinet. Summary of the invention

[0005] The existing integrated distribution box lacks structures that hinder the movement of cables on the inlet and outlet pipes. When the cables are pulled by external forces, the connection stability between them and the electrical device may be reduced, which may easily affect the subsequent use of the integrated distribution box. To solve this problem, the following invention is proposed:

[0006] A comprehensive distribution box comprises a cabinet body, wherein the cabinet body is provided with a fixed side panel and a cabinet door movably connected to the side panel, a plurality of wire tubes are fixedly provided on the outer side of the side panel, the wire tubes are provided with wire holes connecting the cabinet body and the outside world, cables are inserted into the wire holes, a first clamping piece is fixedly provided on the inner side of the side panel, the first clamping piece is provided with a clamping hole connected to the wire hole, a plurality of first clamping arms arranged in an annular manner are provided in the clamping hole, a second clamping piece threadedly connected to the first clamping piece is provided on the side of the first clamping piece, a plurality of second clamping arms arranged in an annular manner are provided on the second clamping piece, the cable passes through the gap between the first clamping arm and the second clamping arm, and is clamped by the double-layer clamping structure formed by the first clamping arm and the second clamping arm after the second clamping piece rotates, and when the cable is pulled by an external force, the friction between the clamping arm and the cable can hinder the cable from moving outward to a certain extent, so as to improve the stability of the connection between the cable and the electrical device in the cabinet.

[0007] Furthermore, each of the first clamping arms is provided with a first arc-shaped clamping surface, and each of the second clamping arms is provided with a second arc-shaped clamping surface, wherein the second clamping surface faces in the opposite direction to the arc surface of the first clamping surface, and the arc-shaped clamping surface can improve the adaptation effect of the first clamping arm and the second clamping arm in clamping cables of different sizes.

The first limiting member is sleeved on the outside of the first fixing column and fits with the first connecting platform. The external thread on the second fixing column and the external thread on the first fixing column have opposite rotation directions, so that the first limiting member prevents the second clamping member from being screwed out along the first fixing column.

[0010] Furthermore, it also includes a third clamping member, the third clamping member is provided with a second connecting platform threadedly connected to the second fixing column, the second connecting platform is fixedly connected to a plurality of third clamping arms arranged in a ring, the third clamping arm is provided with an arc-shaped third clamping surface, the third clamping surface and the arc surface of the second clamping surface are opposite to each other, and when the three clamping surfaces are in contact with the cable at the same time, a multi-layer clamping structure is formed.

[0011] Furthermore, a fixing socket is provided at the end of the second fixing column, and a fixing column is threadedly connected in the fixing socket. The internal thread in the fixing socket and the external thread on the second fixing column have opposite rotation directions. The end of the fixing column is provided with a second limiting member which is sleeved on the outside of the second fixing column and fits with the third clamping member. The second limiting member prevents the third clamping member from being screwed out along the second fixing column.

[0012] Furthermore, the second clamping member and the third clamping member are both provided with a first slot in the shape of an annular prism, the end of the second limiting member is provided with a second slot in the shape of a prism, and the outer periphery of the first limiting member is also prism-shaped, so that the operator can use specific tools to screw in and out the second clamping member, the third clamping member, the first limiting member and the second limiting member.

[0013] Furthermore, the first clamping surface, the second clamping surface and the third clamping surface are each provided with a plurality of spaced-apart clamping blocks, and the clamping blocks increase the friction between the clamping surface and the cable after the two are in contact.

When the cables are pulled by external force, the first clamping surface, the second clamping surface, and the third clamping surface simultaneously hinder the cables from moving out of the cabinet through friction, thereby maintaining the stability of the cables. This can avoid, to a certain extent, the failure of the connection between the cables and other electrical devices in the cabinet due to pulling, and is relatively reliable.

[0028] like Figure 1-Figure 4 As shown, it is a preferred embodiment of the present invention, an integrated distribution box, including a cabinet 1, the cabinet 1 is provided with a fixed side panel 12 and a cabinet door 11 movably connected to the side panel 12, a plurality of wire tubes 2 penetrating the side panel 12 are fixedly provided on the outer side of the side panel 12, the wire tubes 2 are provided with wire holes 3 connecting the cabinet 1 with the outside, and the cables are inserted into the cabinet 1 through the wire holes 3, and a first clamping member 4 is fixedly provided on the inner side of the side panel 12, and a clamping hole 33 connected to the wire hole 3 is provided on the first clamping member 4, and a fixing platform 43 is provided at the center of the clamping hole 33, and four first clamping arms 41 arranged in a ring are provided on the periphery of the fixing platform 43, and a second clamping member 5 is threadedly connected to the inner side of the fixing platform 43. It should be noted here that the inner side of a component defaults to the side facing the inside of the cabinet 1, and four second clamping arms 51 arranged in a ring are provided in the second clamping member 5.

[0029] An outer fixing plate 21 is provided on the wire tube 2, and a plurality of outer fixing holes 22 are provided on the outer fixing plate 21. An inner fixing plate 31 is provided on the first clamping member 4, and a plurality of inner fixing holes 32 are provided on the inner fixing plate 31. Fasteners 23 passing through the side plate 12 are fixedly connected in the inner fixing holes 32 and the outer fixing holes 22 to fix the wire tube 2 and the first clamping member 4 to the side plate 12.

[0030] After the first clamping member 4 is fixedly installed on the side plate 12, the second clamping member 5 is threadedly connected to the fixing platform 43, and a gap is left between the first clamping arm 41 and the second clamping arm 51 for the cable to pass through. The cable passes through the cable hole 3 and passes through the gap. After that, the second clamping member 5 is screwed toward the first clamping member 4 until the first clamping arm 41 and the second clamping arm 51 clamp the cable, forming a double-layer staggered clamping and fixing structure for the cable. When the cable is pulled by an external force, the first clamping arm 41 and the second clamping arm 51 prevent the cable from being easily pulled through friction. Since there are multiple first clamping arms 41 and second clamping arms 51, multiple cables can be clamped and fixed at the same time.

[0031] In this embodiment, each of the first clamping arms 41 is further provided with an arc-shaped concave first clamping surface 42, and each of the second clamping arms 51 is further provided with an arc-shaped concave second clamping surface 52, wherein the arc surfaces of the second clamping surface 52 and the first clamping surface 42 face oppositely, and a plurality of spaced clamping blocks 47 are further provided on the first clamping surface 42 and the second clamping surface 52. After the cable is clamped by the first clamping arm 41 and the second clamping arm 51, the first clamping surface 42 and the second clamping surface 52 are in contact with the cable, and the friction force of the contact surface is increased by the clamping block 47, further increasing the force required for pulling the cable, and at the same time, the arc-shaped first clamping surface 42 and the second clamping surface 52 can better clamp and fix cables of different sizes.

[0032] In this embodiment, a first fixing column 44 is also provided inside the center of the fixing platform 43, a first connecting platform 53 and an annular plate 54 are provided on the second clamping member 5, and the two ends of the second clamping arm 51 are respectively fixedly connected to the first connecting platform 53 and the annular plate 54, and are arranged in an annular shape with the first connecting platform 53 as the center. The first connecting platform 53 is threadedly connected and sleeved on the first fixing column 44. After the second clamping member 5 is rotated, the second clamping arm 51 will rotate with the first fixing column 44 as the center. Further, a second fixing column 45 is also provided inside the center of the first fixing column 44, and the second fixing column 45 is provided with an external thread with a rotation direction opposite to that of the first fixing column 44. A first stopper 7 is threadedly connected to the second fixing column 45, and one end of the first stopper 7 is sleeved on the outer periphery of the first fixing column 44 at intervals, and fits with the first connecting platform 53 on the second clamping member 5 after being screwed in. The external threads on the first fixing column 44 and the second fixing column 45 are in opposite directions, so that the tightening directions of the second clamping member 5 and the first limiting member 7 are also opposite. When the cable is pulled, the first limiting member 7 prevents the second clamping member 5 from being screwed out along the first fixing column 44, thereby ensuring the clamping effect on the cable.

[0033] In this embodiment, a third clamping member 6 is also provided on the inner side of the fixing platform 43, and the third clamping member 6 includes a second connecting platform 63 provided at the center and an annular plate 54 provided at intervals on the outer periphery of the second connecting platform 63, and a third clamping arm 61 having two ends fixedly connected to the second connecting platform 63 and the annular plate 54 is provided between the second connecting platform 63 and the annular plate 54, and the third clamping arm 61 is arranged in a ring shape with the second connecting platform 63 as the center, and a third clamping surface 62 with an arc-shaped inward concave is provided on the third clamping arm 61, wherein the third clamping surface 62 faces the opposite arc surface of the second clamping surface 52, and a plurality of spaced clamping blocks 47 are also provided on the third clamping surface 62. After the cable is clamped by the first clamping surface 42 and the second clamping surface 52, the third clamping member 6 can be screwed toward the first limiter 7, so that the cable can be further clamped by the third clamping surface 62 on the third clamping arm 61, forming a three-layer dislocation clamping structure, and increasing the clamping area of ​​the cable and the force required to pull the cable.

[0034] Furthermore, a fixing socket 46 is provided at the end of the second fixing column 45, and an internal thread with a rotation direction opposite to that of the external thread on the second fixing column 45 is provided in the fixing socket 46, and a fixing plug 81 is connected to the internal thread of the fixing socket 46, and a second stopper 8 is provided at the end of the fixing plug 81, which is sleeved on the outer periphery of the second fixing column 45 and fits with the third clamping member 6. Similarly, since the internal thread of the fixing socket 46 is rotated in the opposite direction to that of the external thread on the second fixing column 45, the second stopper 8 can prevent the third clamping member 6 from being screwed out along the second fixing column 45, ensuring that the clamping of the cable by the third clamping member 6 will not fail.

[0035] In this embodiment, a first slot 55 in the form of an annular hexagonal prism is provided on the second clamping member 5 and the third clamping member 6, and a second slot 82 in the form of a prism is provided at the end of the second limiting member 8. At the same time, the outer periphery of the first limiting member 7 is also in the form of a prism. By using a tool that is compatible with the first slot 55, the second slot 82 and the first limiting member 7, the purpose of quickly screwing the second clamping member 5, the third clamping member 6, the first limiting member 7 and the second limiting member 8 can be achieved.

[0036] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
