As shown in fig. 7-11, the present invention provides a bus bar adapter, which includes a base 1, wherein the base 1 is provided with a plurality of conductive bars 2, the conductive bars 2 may be copper bars, and of course, other conductive materials may also be adopted, such as metal materials, such as aluminum, iron, or some non-metal conductive materials, and the number of the conductive bars 2 may be multiple, and each conductive bar 2 may be arranged on the base 1 at intervals, and the direction of the interval arrangement is actually the second direction in the following text.

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, such an embodiment may be seen in fig. 7 and 12; if the circuit breaker 7 is a four-pole circuit breaker, the number of conductor bars 2 can be four, as can be seen in fig. 13 for this embodiment.

The second nut member 4 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 utility model 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 bar-shaped hole 21, and the second nut member 4 may be a hole wall clamped in the bar-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; one of the flattened part 41 and the hole wall of the strip-shaped hole 21 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 clamping assembly of the second nut piece 4 and the conductive bar 2, so that the second nut piece 4 can be prevented from falling from the conductive bar 2; meanwhile, the cooperation of the clamping protrusion and the clamping groove can actually guide the sliding of the second nut member 4 in the conductive bar 2.

Referring to fig. 1 to 6, fig. 1 is a connection structure diagram of a bus bar system and an embodiment of a bus bar adapter provided by the present invention, fig. 2 is a connection structure diagram of a sliding sleeve, a base body and a first nut member, fig. 3 is a connection structure diagram of a sliding sleeve and a first nut member, fig. 4 is a schematic structural diagram of fig. 3 at another view angle, fig. 5 is a connection structure diagram of a circuit breaker and a base, and fig. 6 is an installation structure diagram of a conductive bar and a base.

The bus bar adapter is mainly used for electrically connecting the circuit breaker 7 and the bus bar system 8, and generally, the circuit breaker 7 and the bus bar adapter are connected by a first threaded connector 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 screw-thread matching component for matching with the first screw-thread connector 71 in the bus bar adapter provided by the embodiment of the present invention, and the installation position of the screw-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 adapter provided in the embodiment of the present invention does not necessarily have only the screw-fitting member that can adjust the mounting position, but may have a screw-fitting member that fixes the mounting position, for example, the screw-fitting member 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 first nut member 3 can slide relatively in the first direction by the sliding sleeve 12, and the first nut member 3 can slide relatively in the second direction by the sliding sleeve 12, so that the first nut member 3 can be adjusted in position 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 can also be provided with a limiting member, and both the limiting member and the top plate body 123 can be used for limiting the position of the first nut member 3 in the third direction so as to prevent the first nut member 3 from being pulled out of 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 the 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 covering portion 121a, and the covering 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.

With reference to fig. 3 and 4, the first nut member 3 is actually installed in a cavity defined by two first plate bodies 121, two second plate bodies 122, a top plate body 123 and a covering portion 121a, the two first plate bodies 121 can limit the first nut member 3 in a first direction, the two second plate bodies 122 can limit the first nut member 3 in a second direction, and the top plate body 123 and the covering portion 121a can limit the first nut member 3 in a third direction.

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-out structure 123a needs to be provided on the top plate body 123 to expose the threaded hole 31, so that the first threaded connecting member 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 wrapping range of the wrapping portion 121a needs to be controlled so as to avoid the wrapping 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 wrapping 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 threaded holes 31 may be two, and the specifications of the two threaded holes 31 may be M6 and M5, respectively.

In addition to different fixed distances and different first threaded connections 71, different models of circuit breakers 7 may also have different spacing distances. Therefore, the bus bar adapter provided by the embodiment of the utility model 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 adapter can be improved to a greater extent.

It is understood that the above-mentioned solution of providing the first nut member 3 and the sliding sleeve 12 to achieve the position adjustment of the first nut member 3 in the first direction and the second direction, and thus the installation of the circuit breakers 7 adapted to different fixed distances, is only an exemplary description of the embodiment of the present invention, and actually, in addition to the above-mentioned solution, other solutions can be adopted to achieve the adaptive assembly of the circuit breakers 7 adapted to different fixed distances, for example, the solution can be achieved by providing a plurality of threaded installation holes.

Referring to fig. 14-15, fig. 14 is a schematic structural view of the elongated base, and fig. 15 is a structural view of the connection between the base and the elongated 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 utility model 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, various forms of fixed connection modes such as riveting, welding, bonding, clamping and the like can be adopted between the lengthened seat 6 and the base 1.

Taking clamping as an example, the lengthened seat 6 may be provided with a butt joint block 61, a clamping hook 62 and an inserting strip 63, and correspondingly, the base 1 may be provided with a butt joint 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.
