As described in the background section, the bus bar adaptor is mainly used to electrically connect the circuit breaker 7 and the bus bar system 8, and generally, the circuit breaker 7 and the bus bar adaptor are connected by a first threaded connection 71. In a specific implementation, the first threaded connector 71 may be a screw or a bolt, the bus bar adapter may be provided with a threaded hole, the circuit breaker 7 may be provided with a through hole, and the first threaded connector 71 may pass through the through hole of the circuit breaker 7 and be in threaded connection with the threaded hole of the bus bar adapter, so that the circuit breaker 7 may be fixed to the bus bar adapter.

However, the conventional bus bar adaptor has a certain arrangement position of the threaded hole, which results in that the bus bar adaptor can only adapt to the installation of one type of circuit breaker 7, and the compatibility is poor. When the model of the circuit breaker 7 is changed, a new bus bar adapter needs to be designed again, which causes more types of bus bar adapters and is not beneficial to management.

To this end, the embodiment of the present invention provides a bus bar adapter, as shown in fig. 1 and fig. 2, the bus bar adapter includes a base 1, the base 1 is mounted with a conductive bar 2 and a first nut member 3, the first nut member 3 is slidably connected with the base 1 for adjusting a mounting position of the first nut member 3 on the base 1, and the first nut member 3 is provided with a threaded hole 31.

By adopting the structure, the mounting position of the first nut member 3 of the bus adapter on the base 1 can be adjusted, the bus adapter can be suitable for mounting of circuit breakers 7 of different types, so that the compatibility is improved, meanwhile, the types of the bus adapter can be reduced, and the management and the use of the bus adapter can be facilitated.

It should be noted that the first nut member 3 is only a specific form of the thread matching component for matching with the first thread connecting piece 71 in the bus bar adapter provided by the embodiment of the present invention, and the installation position of the thread matching component can be adjusted, so as to achieve the technical purpose of adapting to the installation of different types of circuit breakers 7; however, the bus bar adaptor provided in the embodiment of the present invention does not necessarily have only the screw-fit component that can adjust the mounting position, but may have a screw-fit component that fixes the mounting position, for example, the screw-fit component that fixes the mounting position may be a screw hole or the like provided in the base 1; that is, there may be only a portion of the screw-fit components whose mounting positions are adjustable, which is also a technical solution that may be adopted in specific practice.

The specific form of the sliding fit structure of the first nut member 3 and the base 1 can be various, and in specific practice, a person skilled in the art can select the sliding fit structure according to actual needs as long as the corresponding technical effect can be achieved. Likewise, the sliding direction of the first nut member 3 on the base 1 is not limited.

In a specific solution, as shown in fig. 2-4, the base 1 may include a base body 11 and a sliding sleeve 12, the base body 11 may be provided with a first sliding rail 111 extending along a first direction, the sliding sleeve 12 may be slidably connected to the first sliding rail 111, the first nut member 3 may be mounted on the sliding sleeve 12 and can slide in a second direction within the sliding sleeve 12, and the first direction and the second direction may be disposed at an included angle.

In this way, the relative sliding of the first nut member 3 in the first direction can be achieved by the sliding sleeve 12, and the relative sliding of the first nut member 3 in the second direction can be achieved within the sliding sleeve 12, so that the position adjustment of the first nut member 3 can be performed in both the first direction and the second direction, and the adjustable range of the first nut member 3 is larger. Thus, embodiments of the present invention provide bus bar adapters that can accommodate the installation of bus bar adapters having different fixed spacings in a first direction and/or different fixed spacings in a second direction.

Here, the fixed pitch in the first direction refers to a pitch of two first screw connectors 71 in the first direction, and the fixed pitch in the second direction refers to a pitch of two first screw connectors 71 in the second direction. The specific value of the included angle between the first direction and the second direction is not limited herein, and in particular practice, the included angle between the first direction and the second direction may be set by those skilled in the art according to actual needs, and in general, the included angle between the first direction and the second direction may be 90 degrees.

With continued reference to fig. 3 and fig. 4, the sliding sleeve 12 may include a top plate 123 and a peripheral plate, the peripheral plate may include two first plates 121 oppositely disposed in a first direction and two second plates 122 oppositely disposed in a second direction, and both the first plates 121 and the second plates 122 are connected to the peripheral plate 123; the second plate 122 may be slidably connected to the first slide rail 111, a specific form of the sliding fit structure between the second plate 122 and the first slide rail 111 is not limited herein, in the embodiment of fig. 3, the second plate 122 may be bent to form a sliding slot structure on the second plate 122, so as to form a sliding fit with the first slide rail 111 of the seat body 11, and the sliding fit between the second plate 122 and the first slide rail 111 may have a certain interference in the second direction, so that the sliding sleeve 12 may be clamped in the first slide rail 111, so as to ensure the installation position of the sliding sleeve 12 without an external force; the first nut member 3 may be clearance-fitted with the second plate bodies 122 in the second direction, so that the first nut member 3 may slide between the two second plate bodies 122 in the second direction.

The sliding sleeve 12 may also be provided with a stop member, and both the stop member and the top plate body 123 may be used to limit the position of the first nut member 3 in the third direction, so as to prevent the first nut member 3 from being removed from the sliding sleeve 12 in the third direction. The third direction may be perpendicular to both the first direction and the second direction.

Here, the embodiment of the present invention is not limited to a specific structural form of the limiting member, and in practical applications, a person skilled in the art may set the limiting member as needed as long as the technical effects described above can be achieved. In an exemplary aspect, at least one of the first plate body 121 and the second plate body 122 may be provided with a covered edge portion 121a, and the covered edge portion 121a may serve as the aforementioned limiting member; in the embodiment of fig. 4, the hemming portion 121a may be formed only by the first plate body 121.

The end of the first nut member 3 facing the top plate body 123 can be used as an insertion end, and in this case, a hollowed structure 123a needs to be provided on the top plate body 123 to expose the threaded hole 31, so that the first threaded connector 71 can be inserted into the threaded hole 31 from the top plate body 123. Alternatively, the end of the first nut member 3 away from the top plate body 123 may be used as the insertion end, and in this case, the edge-covering range of the edge-covering portion 121a needs to be controlled so as to avoid the edge-covering portion 121a from shielding the threaded hole 31, and the first threaded connector 71 can be inserted into the threaded hole 31 from the position of the edge-covering portion 121 a.

Further, the first nut member 3 may be provided with a tapered guide hole 32, the guide hole 32 may communicate with the threaded hole 31, and the diameter of the guide hole 32 may be gradually reduced in a direction approaching the threaded hole 31.

During assembly, the first threaded connector 71 can contact the guide hole 32 first and can be guided through the hole wall of the guide hole 32, so that the first threaded connector 71 can be inserted into the threaded hole 31 more easily; further, the process of guiding the first threaded connector 71 by the hole wall of the guide hole 32 is also actually the process of adjusting the mounting position of the first threaded connector 71 to the first nut member 3.

Further, the first nut member 3 may be provided with a plurality of threaded holes 31, and the hole diameter of each threaded hole 31 may be different. That is, the first nut member 3 may also be provided with screw holes 31 of various specifications to accommodate combination fitting with first screw-threaded connecting members 71 of different specifications.

Here, the embodiment of the present invention does not limit the number of the threaded holes 31 provided in one first nut member 3, and in particular, in practice, the skilled person can set the number according to actual needs. In general, the number of the screw holes 31 may be two, and the specifications of the two screw holes 31 may be M6 and M5, respectively.

In addition to different fixed distances and different first threaded connections 71, different types of circuit breakers 7 may have different spacing distances. Therefore, the bus bar adaptor provided by the embodiment of the invention can be provided with a corresponding improved structure to adapt to the assembly of the circuit breakers 7 with different phase distances, so that the compatibility of the bus bar adaptor can be improved to a greater extent.

The conductive bar 2 can be a copper bar generally, of course, other conductive materials can also be adopted, for example, metal materials such as aluminum, iron, or some non-metal conductive materials, the number of the conductive bars can be multiple, and each conductive bar 2 can be arranged on the base 1 at intervals, and the direction of the interval arrangement is actually the aforementioned second direction. Here, the embodiment of the present invention does not limit the number of the conductive bars 2, which is specifically related to the model of the circuit breaker 7; if the circuit breaker 7 is a three-pole circuit breaker, the number of the conducting bars 2 may be three, and this embodiment can be seen in fig. 7 and 10; if the circuit breaker 7 is a four-pole circuit breaker, the number of conductor bars 2 may be four, as can be seen in fig. 11.

At least one of the conductive bars 2 may be configured with strip-shaped holes 21 extending along the aforementioned direction arranged at intervals; a second nut member 4 may be further included, the second nut member 4 being capable of being opposed to the strip-shaped hole 21 and being slidable in a direction set at intervals for connection with the second screw-connection member 72 that fixes the conductive column 73.

The second threaded connector 72 can slide along the direction of the interval arrangement, so that the assembly of the circuit breakers 7 with different interval distances can be adapted, and the compatibility of the bus bar adapter provided by the embodiment of the invention can be further improved.

Taking the scheme of three conductive bars 2 as an example, the three conductive bars 2 may be provided with the strip-shaped holes 21 and the second nut members 4 corresponding to the corresponding strip-shaped holes 21, and at this time, the connection position of each conductive bar 2 and the second threaded connection member 72 may be adjustable; alternatively, one of the three conductor bars 2 may have a screw connection hole with a fixed position as a reference for installation, and the other two conductor bars 2 may have the strip-shaped hole 21 and the second nut member 4, so as to meet the use requirement.

The second nut member 4 may be slidably connected to the base 1, may also be slidably connected to the conductive bar 2, and may also be slidably connected to the base 1 and the conductive bar 2 at the same time.

In the embodiment of the drawings, as shown in fig. 8, the second nut member 4 may be slidably connected to the conductive bar 2, specifically, slidably connected to a hole wall of the strip-shaped hole 21, and the second nut member 4 may be clamped on the hole wall of the strip-shaped hole 21, so as to prevent the second nut member 4 from being separated from the conductive bar 2 in the third direction.

In detail, referring to fig. 9, the peripheral wall of the second nut member 4 may be provided with a flattened portion 41 for increasing the sliding contact area between the second nut member 4 and the strip-shaped hole 21, so as to improve the stability of the sliding connection between the second nut member 4 and the strip-shaped hole 21; in the hole walls of the flat cutting part 41 and the strip-shaped hole 21, one of them may be provided with a clamping protrusion (not shown in the figure), and the other may be provided with a clamping groove (not shown in the figure), and the clamping protrusion may be clamped into the clamping groove to realize the clamping assembly of the second nut piece 4 and the conductive bar 2, and meanwhile, the matching of the clamping protrusion and the clamping groove may actually guide the sliding of the second nut piece 4 in the conductive bar 2.

With reference to fig. 10, during specific assembly, the second threaded connector 72 may penetrate into the circuit breaker 7, then the conductive post 73 (specifically, a copper post, or other conductive material) may be externally installed on the second threaded connector 72 and overlapped with the circuit breaker 7, then the second threaded connector 72 may be butted with the second nut 4 and the second threaded connector 72 may be screwed, and in the process of screwing the second threaded connector 72, the second threaded connector 72 may further adjust the position of the corresponding second nut 4 to adapt to the distance between the phases of the circuit breaker 7.

Referring to fig. 12, fig. 12 is a schematic structural diagram of another embodiment of the bus bar adapter of the present invention.

Different from the solution of providing the strip-shaped hole 21 and the second nut member 4 on the conductive bar 2, the embodiment of the present invention provides another solution that can adapt to the installation of circuit breakers 7 with different spacing distances.

Specifically, as shown in fig. 12, a flexible conductive plate 5 may be further included, one end of the flexible conductive plate 5 may be connected to the conductive bar 2, and the other end may be connected to the circuit breaker 7, and since the flexible conductive plate 5 has a flexible deformation capability, it may be well adapted to the installation of circuit breakers 7 with different inter-phase distances, and may further ensure the compatibility of the bus bar adaptor.

Here, the embodiment of the present invention does not limit the material of the flexible conductive plate 5, and in practice, a person skilled in the art may select the material according to actual needs.

Referring to fig. 13-14, fig. 13 is a schematic structural view of the extension base, and fig. 14 is a structural view of the connection between the base and the extension base.

In practical application, there are also circuit breakers 7 integrated with a leakage detection module or an automatic reclosing function, and the length (the size in the first direction) of these circuit breakers 7 is long, resulting in a great increase in the fixed distance, and the conventional bus adapter cannot meet the requirements of fixed installation.

Therefore, the bus bar adapter provided by the embodiment of the invention may further include an elongated seat 6, the elongated seat 6 may be connected to the base 1 to extend the length of the entire bus bar adapter, and the elongated seat 6 may be provided with a second slide rail 64 corresponding to the first slide rail 111, and the second slide rail 64 may also extend along the first direction and may be connected to the first slide rail 111, so that the sliding sleeve 12 may also be slidably connected to the second slide rail 64, so that the first nut member 3 may also slide into the elongated seat 6, thereby adapting to the installation of the breaker 7 with a longer length.

The fixed connection between the extension base 6 and the base 1 is not limited herein, as long as the reliable connection between the two can be ensured. For example, the elongated seat 6 and the base 1 may be connected by a threaded connection in the form of a screw, a bolt, or the like; or, the lengthening seat 6 and the base 1 can be fixedly connected in various forms such as riveting, welding, bonding, clamping and the like.

Taking clamping as an example, the lengthened seat 6 may be provided with an abutting block 61, a clamping hook 62 and an inserting strip 63, and correspondingly, the base 1 may be provided with an abutting groove 112, a clamping groove and an inserting groove. During specific assembly, the inserting strip 63 can be inserted into the inserting groove to realize the connection of the lengthening seat 6 and the base 1 in the first direction, the clamping hook 62 can be clamped into the clamping groove to realize the connection of the lengthening seat 6 and the base 1 in the third direction, and the butt joint block 61 can be clamped into the butt joint groove 112 to ensure the relative fixation of the lengthening seat 6 and the base 1 in the second direction.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
