Specifically, the flexible connector is used to bend the first flexible connection plate along a first direction under the action of an external force, and / or bend the second flexible connection plate along a second direction interlaced with the first direction, so as to adjust the position of the first connector and / or the second connector in space; wherein the first flexible connection plate and the second flexible connection plate both have two opposite and parallel facades, the first direction is a direction from one facade of the first flexible connection plate to the other facade or a corresponding reverse direction, and the second direction is a direction from one facade of the second flexible connection plate to the other facade or a corresponding reverse direction.

DETAILED DESCRIPTION

[0014] In the related art, the low-voltage busbar and the low-voltage switch are mostly connected electrically by a rigid connection device. The applicability of such a rigid connection device is very poor, which is mainly manifested in the following aspects: when the low-voltage switch has serious heating, burning and other faults and needs to be replaced, since the low-voltage switches produced by different manufacturers cannot be unified in size, it is often necessary to re-customize the rigid connection device when replacing the low-voltage switch to adapt to the new low-voltage switch, which leads to low efficiency of fault repair of the low-voltage switch, which will inevitably prolong the fault time and increase the difficulty and workload of fault repair. In view of this, the present application proposes a flexible connection device for establishing an electrical connection relationship in the following embodiments, which has a wide range of application and can effectively solve the above-mentioned drawbacks existing in the related art.

[0015] In order to make the purpose, technical solutions and advantages of the present application more obvious and easy to understand, the present application will be clearly and completely described below in conjunction with the embodiments of the present application and the corresponding drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. It should be understood that the embodiments of the present application described below are only used to explain the present application and are not used to limit the present application, that is, based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0016] See also Figure 1 , Figure 1: is a structural schematic diagram of a flexible connection device. This embodiment provides a flexible connection device for establishing an electrical connection relationship, which is used to electrically connect between a first electrical device and a second electrical device to establish an electrical connection between the first electrical device and the second electrical device, and includes a first joint 100, a second joint 200, a first fastening structure 400, a second fastening structure 500 and a flexible connector 300, one end of the first joint 100 is arranged on one end of the flexible connector 300, one end of the second joint 200 is arranged on the other end of the flexible connector 300, the other ends of the first joint 100 and the second joint 200 are both suspended, the first joint 100 and the second joint 200 are electrically connected to the flexible connector 300 respectively, the first fastening structure 400 is arranged on the first joint 100, and the second fastening structure 500 is arranged on the second joint 200. Specifically, the first connector 100 is used to be set on the first electrical equipment through the first fastening structure 400 to be electrically connected to the first electrical equipment; the second connector 200 is used to be set on the second electrical equipment through the second fastening structure 500 to be electrically connected to the second electrical equipment; the flexible connector 300 is used to twist under the action of external force to adjust the position of the first connector 100 and / or the second connector 200 in space, so that the positions of the first connector 100 and the second connector 200 in space are respectively adapted to the positions of the first electrical equipment and the second electrical equipment.

[0017] That is to say, when an electrical connection relationship is established between the first electrical device and the second electrical device through the flexible connection device, the flexible connection device can be placed between the first electrical device and the second electrical device, and then the flexible connection member 300 can be bent to cause it to twist, thereby adjusting the position of the first connector 100 and / or the second connector 200 in space, so that the positions of the first connector 100 and the second connector 200 in space are respectively adapted to the positions of the first electrical device and the second electrical device, and finally, the first connector 100 is set on the first electrical device through the first fastening structure 400, and the second connector 200 is set on the second electrical device through the second fastening structure 500, and thus the electrical connection between the first electrical device and the second electrical device is realized through the flexible connection device.

[0018] Typically, a low-voltage busbar and a low-voltage switch are provided in a low-voltage switch cabinet. The low-voltage busbar includes a main busbar and a branch busbar. The main busbar is a large current conductor used to collect and distribute electrical energy in the low-voltage switch cabinet, while the branch busbar is a small current conductor drawn from the main busbar and used to supply power to specific electrical equipment or branch circuits. Therefore, the main busbar and the branch busbar, the main busbar and conventional electrical equipment, and the branch busbar and specific electrical equipment or branch circuits all need to be electrically connected through a low-voltage switch. In this case, the main busbar and the low-voltage switch, and the branch busbar and the low-voltage switch can be electrically connected through the flexible connection device of this embodiment.

[0019] In this embodiment, the flexible connection device can be used between any two electrical devices that need to be electrically connected in this field, not limited to the low-voltage busbar and the low-voltage switch, such as: other electrical connections in the low-voltage switch cabinet except the low-voltage busbar and the low-voltage switch; electrical connections inside the medium / high-voltage switch cabinet; electrical connections between the transformer outlet and the low / medium / high-voltage busbar. It should be noted that as to which two electrical devices the flexible connection device of this embodiment is used between, it can be set according to actual needs, and this application does not make a sole limitation on this.

[0020] In this embodiment, the flexible connection device as a whole can be made of materials commonly used in the art with good conductivity, elasticity and corrosion resistance, such as copper, copper alloys (such as phosphor bronze and beryllium bronze), aluminum, aluminum alloys, composite metals (such as copper-clad aluminum and metal braids), conductive rubber, etc., which can be selected according to actual needs, and this application does not make a sole limitation on this. Preferably, the flexible connection device of this embodiment is made of T2Y copper as a whole.

[0021] As can be seen from the above, if the flexible connection device is applied between the low-voltage busbar and the low-voltage switch, that is, the first electrical device is the low-voltage busbar and the second electrical device is the low-voltage switch, then when replacing a low-voltage switch that has a serious heating, burning or other faults, even if the specifications of the two low-voltage switches before and after the replacement are different, there is no need to re-customize the rigid connection device electrically connected between the low-voltage busbar and the low-voltage switch as in the traditional solution. It is only necessary to adjust the position of the first connector 100 and / or the second connector 200 in space by twisting the flexible connector 300 to adapt to the replaced low-voltage switch. In other words, compared with the rigid connection device in the traditional solution, the flexible connection device of this embodiment has better applicability. When the low-voltage switch has a serious heating, burning or other faults and needs to be replaced, it can not only improve the efficiency of fault repair and shorten the fault time, but also reduce the difficulty and workload of fault repair.

[0022] In some embodiments, see Figure 1The flexible connector 300 includes a first adapter 310, a second adapter 320, a first flexible connection plate 330 and a second flexible connection plate 340. The opposite ends of the first flexible connection plate 330 are respectively arranged on one side of the first adapter 310 and on one side of the second adapter 320. The other side of the first adapter 310 is arranged on the end of the first connector 100 that is not suspended. One end of the second flexible connection plate 340 is arranged on the other side of the second adapter 320. The other end of the second flexible connection plate 340 is arranged on the end of the second connector 200 that is not suspended. The first connector 100, the first adapter 310, the first flexible connection plate 330, the second adapter 320, the second flexible connection plate 340 and the second connector 200 are electrically connected in sequence, and the first flexible connection plate 330 and the second flexible connection plate 340 are alternately arranged. It can be understood that since the first flexible connecting plate 330 and the second flexible connecting plate 340 are both plate-like structures, the first flexible connecting plate 330 and the second flexible connecting plate 340 both have two opposite and parallel facades, so the first flexible connecting plate 330 and the second flexible connecting plate 340 are staggered, which is mainly manifested in that the facade of the first flexible connecting plate 330 is staggered with the facade of the second flexible connecting plate 340; preferably, the facade of the first flexible connecting plate 330 is perpendicular to the facade of the second flexible connecting plate 340. In addition, it should be noted that the first flexible connecting plate 330 and the second flexible connecting plate 340 preferably both include a plurality of stacked copper foils, and the thickness of a single copper foil is 0.03~1mm. It should also be noted that any two adjacent structures between the first connector 100, the first adapter 310, the first flexible connecting plate 330, the second adapter 320, the second flexible connecting plate 340 and the second connector 200 can be connected by welding, crimping or integral molding.

[0023] Specifically, the flexible connector 300 is used to bend the first flexible connection plate 330 along a first direction and / or bend the second flexible connection plate 340 along a second direction interlaced with the first direction under the action of an external force, so as to adjust the position of the first connector 100 and / or the second connector 200 in space, so that the positions of the first connector 100 and the second connector 200 in space are respectively adapted to the positions of the first electrical device and the second electrical device. The first direction is a direction from the first external surface of the first flexible connection plate 330 to the second external surface, or the opposite direction from the second external surface of the first flexible connection plate 330 to the first external surface; similarly, the second direction is a direction from the first external surface of the second flexible connection plate 340 to the second external surface, or the opposite direction from the second external surface of the second flexible connection plate 340 to the first external surface. It can be understood that the first direction is actually two opposite directions perpendicular to the two outer facades of the first flexible connection plate 330 and outward, and the second direction is actually two opposite directions perpendicular to the two outer facades of the second flexible connection plate 340 and outward. Since the first flexible connection plate 330 and the second flexible connection plate 340 are staggered, the first direction and the second direction are also staggered. When the outer facade of the first flexible connection plate 330 is perpendicular to the outer facade of the second flexible connection plate 340, the first direction and the second direction are also perpendicular.

[0024] That is to say, when an electrical connection relationship is established between the first electrical device and the second electrical device through the flexible connection device, the flexible connection device can be placed between the first electrical device and the second electrical device, and then the first flexible connection plate 330 and / or the second flexible connection plate 340 are bent, so that the first flexible connection plate 330 and / or the second flexible connection plate 340 are bent, thereby adjusting the position of the first connector 100 and / or the second connector 200 in space, so that the positions of the first connector 100 and the second connector 200 in space are respectively adapted to the positions of the first electrical device and the second electrical device, and finally, the first connector 100 is set on the first electrical device through the first fastening structure 400, and the second connector 200 is set on the second electrical device through the second fastening structure 500, so that the electrical connection between the first electrical device and the second electrical device is realized through the flexible connection device. It can be understood that since the first direction and the second direction are staggered (preferably perpendicular), during the bending process of the first flexible connecting plate 330 and / or the second flexible connecting plate 340, the first joint 100 and / or the second joint 200 can be moved in six directions of up, down, left, right, front and back, so that the position of the first joint 100 and / or the second joint 200 in space can be adjusted within a predetermined range, and the predetermined range mainly depends on the size and degree of bendability of the first flexible connecting plate 330 and the second flexible connecting plate 340.

[0025] As one embodiment, the first adapter 310 includes a first adapter plate 311, and the second adapter 320 includes a second adapter plate 321. The thickness of the first adapter plate 311 and the second adapter plate 321 are the same and equal to the thickness of the first connector 100, and the thickness of the second connector 200 is the same as the thickness of the first connector 100. It can be understood that the first adapter plate 311 and the second adapter plate 321 are both disc-shaped structures. Figure 1 As can be seen from the previous description of the flexible connection device, the length direction of the first connector 100, the first flexible connection plate 330, the second flexible connection plate 340, and the second connector 200 is consistent with the thickness direction of the first adapter plate 311 and the second adapter plate 321, and the thickness direction of the first connector 100 and the second connector 200 is perpendicular to the thickness direction of the first adapter plate 311 and the second adapter plate 321. Therefore, in this embodiment, the thickness of the first adapter plate 311 and the second adapter plate 321 is set to be the same and equal to the thickness of the first connector 100 (equivalent to the second connector 200), which can ensure the current carrying capacity (i.e., the ability to carry current through) of the first adapter 310 and the second adapter 320, thereby improving the overall conductive performance of the flexible connection device.

[0026] In some embodiments, see Figure 1 , the first fastening structure 400 includes a first fastener (not shown) and a first fixing hole 410 provided on the first connector 100; the second fastening structure 500 includes a second fastener (not shown) and a second fixing hole 510 provided on the second connector 200. Specifically, the first fixing hole 410 is used to align with the first mounting hole on the first electrical device; the first fastener is used to be inserted into the first mounting hole through the first fixing hole 410 to set the first connector 100 on the first electrical device and electrically connect the first electrical device; the second fixing hole 510 is used to align with the second mounting hole on the second electrical device; the second fastener is used to be inserted into the second mounting hole through the second fixing hole 510 to set the second connector 200 on the second electrical device and electrically connect the second electrical device.

[0027] That is to say, in the process of establishing an electrical connection relationship between the first electrical device and the second electrical device through the flexible connection device, the position of the first connector 100 and / or the second connector 200 in space can be adjusted by bending the first flexible connection plate 330 and / or the second flexible connection plate 340. When the positions of the first connector 100 and the second connector 200 in space are adjusted to respectively adapt to the positions of the first electrical device and the second electrical device in space, the first fixing hole 410 on the first connector 100 will be aligned with the first mounting hole on the first electrical device, and the second fixing hole 510 on the second connector 200 will be aligned with the second mounting hole on the second electrical device. Then, the first fastener is inserted into the first mounting hole through the first fixing hole 410, and the second fastener is inserted into the second mounting hole through the second fixing hole 510, thereby realizing the relative fixation and electrical connection between the first connector 100 and the first electrical device, and the relative fixation and electrical connection between the second connector 200 and the second electrical device.

[0028] As one embodiment, the first fastener and the second fastener are both bolts, the first mounting hole and the second mounting hole are both screw holes, and the first fixing hole 410 and the second fixing hole 510 are both waist holes and through holes; wherein the hole diameter of the through hole is adapted to the diameter of the bolt, the size of the waist hole in the short axis direction is adapted to the diameter of the bolt, and the size in the long axis direction is larger than the diameter of the bolt. In this embodiment, the form of the first fixing hole 410 and the second fixing hole 510 can be: the first fixing hole 410 and the second fixing hole 510 are both waist holes; or, the first fixing hole 410 and the second fixing hole 510 are both through holes; or, the first fixing hole 410 is a waist hole, and the second fixing hole 510 is a through hole; or, the first fixing hole 410 is a through hole, and the second fixing hole 510 is a waist hole. Moreover, the number of the first fixing holes 410 and the second fixing holes 510 is not limited to one, that is, one or more first fixing holes 410 can be opened on the first joint 100, and one or more second fixing holes 510 can also be opened on the second joint 200. When multiple first fixing holes 410 / second fixing holes 510 are opened on the first joint 100 / second joint 200, the multiple first fixing holes 410 / second fixing holes 510 are preferably arranged at intervals along the length direction of the first joint 100 / second joint 200.

[0029] It can be understood that, taking the example that the first fastener is the first bolt, the first fixing hole 410 on the first connector 100 is the first waist hole, and the first mounting hole on the first electrical device is the first screw hole, when the first waist hole is aligned with the first screw hole on the first electrical device, and the first bolt is inserted into the first screw hole through the first waist hole, since the size of the first waist hole in the long axis direction is larger than the diameter of the first bolt, the first bolt can be slid in the first waist hole along the long axis direction of the first waist hole to adjust the position of the first bolt in the first waist hole, thereby achieving fine-tuning of the relative position between the first connector 100 and the first electrical device, which can further improve the applicability of the flexible connection device. Furthermore, taking the example that a plurality of first fixing holes 410 are provided on the first connector 100, different first fixing holes 410 can be aligned with the first mounting hole, and the first fastener can be inserted into the first mounting hole through different first fixing holes 410. At this time, the fine-tuning range of the relative position between the first connector 100 and the first electrical device will be wider, and the applicability of the flexible connection device will be better. In addition, it should be noted that Figure 1 As an example only, it shows the situation where two waist holes are opened on the first joint 100 and one through hole is opened on the second joint 200. However, the form and number of the first fixing hole 410 and the second fixing hole 510 are set according to actual needs, and this application does not make the sole limitation on this.

[0030] In some embodiments, the outer surfaces of the first connector 100 and the second connector 200 are coated with a silver-plated layer to enhance the flow capacity of the first connector 100 and the second connector 200; of course, it is not limited to silver plating on the outer surfaces of the first connector 100 and the second connector 200. In other embodiments, other materials commonly used in the art to enhance the flow capacity may also be plated on the outer surfaces of the first connector 100 and the second connector 200, such as gold, nickel, chromium, palladium, etc. The specific selection can be based on actual needs, and this application does not make a sole limitation on this. Furthermore, the outer surface of the flexible connector 300 is coated with a tin-plated layer, and preferably the outer surfaces of the first flexible connecting plate 330 and the second flexible connecting plate 340 are coated with a tin-plated layer to enhance the flow capacity of the flexible connector 300 and improve its corrosion resistance. Of course, it is not limited to tin plating on the outer surface of the flexible connector 300. In other embodiments, other materials commonly used in the field to enhance flow capacity and corrosion resistance may also be plated on the outer surface of the flexible connector 300, such as gold, nickel, chromium, palladium, etc. The specific selection can be based on actual needs, and the present application does not make a sole limitation on this.

[0031] In some embodiments, an insulating layer is coated on the outer surface of the flexible connection device, that is, the outer surfaces of the first connector 100, the second connector 200 and the flexible connector 300 are all coated with an insulating layer (equivalent to the outer surfaces of the silver-plated layer and the tin-plated layer being coated with an insulating layer), so as to improve the insulation performance of the flexible connection device. In addition, it should be noted that the form of the insulating layer can be commonly used in the art, such as a wound insulating tape, a coated insulating paint, a sleeved insulating sleeve, a sprayed insulating powder, and a coated heat shrink tube, etc. The material of the insulating layer can be commonly used in the art, such as rubber (such as natural rubber and synthetic rubber), plastic (such as polyvinyl chloride, polyethylene and polytetrafluoroethylene), fiber material (such as glass fiber and aramid fiber), etc., which can be selected according to actual needs, and this application does not make a sole limitation on this. Preferably, the insulating layer is a heat shrink tube coated on the outer surface of the flexible connection device, and heat shrink sleeves of different voltage levels can be used according to different usage scenarios, and this application does not make a sole limitation on this.

[0032] The above embodiments are only preferred implementations of the present application, and are not the only limitations on the contents related to the flexible connection device; in this regard, those skilled in the art can flexibly set them according to the actual application scenarios based on the above embodiments. It can be understood that, through the implementation of the above embodiments of the present application, the first joint 100, the second joint 200, the first fastening structure 400, the second fastening structure 500 and the flexible connector 300 constitute a flexible connection device, the first joint 100 is arranged on one end of the flexible connector 300, the second joint 200 is arranged on the other end of the flexible connector 300, the first joint 100 and the second joint 200 are both electrically connected to the flexible connector 300, the first fastening structure 400 is arranged on the first joint 100, and the second fastening structure 500 is arranged on the second joint 200. In actual applications, when an electrical connection is established between a first electrical device and a second electrical device, the flexible connection device can be placed between the first electrical device and the second electrical device, and then the flexible connector 300 can be bent to twist it, thereby adjusting the position of the first connector 100 and / or the second connector 200 in space, so that the positions of the first connector 100 and the second connector 200 in space are respectively adapted to the positions of the first electrical device and the second electrical device, and finally, the first connector 100 is set on the first electrical device through the first fastening structure 400, and the second connector 200 is set on the second electrical device through the second fastening structure 500, so that the electrical connection between the first electrical device and the second electrical device is realized through the flexible connection device. It is understandable that if the flexible connection device is applied between the low-voltage busbar and the low-voltage switch, that is, the first electrical device is the low-voltage busbar and the second electrical device is the low-voltage switch, then when replacing a low-voltage switch that has a serious heating, burning or other fault, even if the specifications of the two low-voltage switches before and after the replacement are different, there is no need to re-customize the rigid connection device electrically connected between the low-voltage busbar and the low-voltage switch as in the traditional solution. It is only necessary to adjust the position of the first connector 100 and / or the second connector 200 in space by twisting the flexible connector 300 to adapt to the replaced low-voltage switch. In other words, compared with the rigid connection device in the traditional solution, the flexible connection device of the present application has better applicability. When the low-voltage switch has a serious heating, burning or other fault and needs to be replaced, it can not only improve the efficiency of fault repair and shorten the fault time, but also reduce the difficulty and workload of fault repair.
