As shown in fig. 1 to 5, the present invention provides an adapter, which includes a housing 1, wherein the housing 1 may be made of an insulating material such as plastic, so as to ensure the safe use of the adapter. The inside of casing 1 is equipped with electrically conductive piece 2, and this electrically conductive piece 2 specifically can be common electric conductor such as electrically conductive copper bar, and its one end and circuit breaker 6 electricity are connected, and another end can be connected with the generating line system 4 electricity in the peripheral hardware switch board, and then realizes the switching function. The peripheral power distribution cabinet can be a cabinet body in various forms such as a fixed separation cabinet and an electric appliance cabinet.

In particular, the other end of the conductive element 2 may be provided with a plug contact 3, which plug contact 3 comprises two conductive tabs 31 arranged opposite each other. In the assembled state, referring to fig. 8 and 9, the adaptor can be plugged into the bus bar system 4 through the plug contact 3, and the two conductive inserting sheets 31 clamp the main bus bar 41 of the bus bar system 4 to complete power taking. The main busbar 41 is mainly referred to as an incoming main busbar.

Compared with the prior art, the adapter provided by the invention has the advantages that the plug contact 3 is connected with the bus system 4 through plug connection, additional copper bars, bolts and the like for fastening connection are not needed, the wire inlet connection structure between the adapter and the wire inlet main bus bar can be simplified, the installation efficiency is improved, and the use cost is reduced; and when not in use or in need of maintenance and replacement, even if the bus system 4 is not powered off, the adapter can be directly pulled out, and the function of hot plug (live plug) can be realized.

In addition, the plug-in base in the prior art can be used only by being matched with a special plug-in molded case circuit breaker, so that the limitation is large, the use cost is relatively high, the structure of the circuit breaker 6 is not specially required by the adapter provided by the invention, the molded case circuit breaker in a general form can be used, the use cost can be further reduced, and the popularization and the use are facilitated.

As shown in fig. 4, one end (upper end in the drawing) of the conductive tab 31 is connected to the conductive member 2, and the end (lower end in the drawing) away from the fixed end is a free end. When an external force acts on the conductive insert 31, the free end of the conductive insert 31 can rotate around the connection position of the conductive insert and the conductive piece 2, and when the external force disappears, the free end of the conductive insert 31 can return to the original position, that is, the conductive insert 31 can have a certain elasticity.

In this way, in one embodiment, the elasticity of the conductive insert 31 itself can be utilized to reliably clamp the main busbar 41. In detail, the shortest distance between the two conductive tabs 31 is set to be smaller than the thickness of the main bus bar 41, when the adaptor is plugged into the bus bar system 4, the main bus bar 41 can generate an outward pushing force on the free ends of the conductive tabs 31 to force the conductive tabs 31 to open outwards, and the main bus bar 41 can push into the gap between the two conductive tabs 31; at this time, under the action of the elastic force of the conductive insert 31, the free end of the conductive insert 31 has a tendency to rotate inwards to restore to the original state, i.e. the conductive insert 31 itself can generate an inward abutting force on the main busbar 41, so as to ensure reliable electrical connection between the conductive insert 31 and the main busbar 41.

The description of the azimuth or positional relationship such as "inner", "outer", etc. is referred to herein with reference to fig. 4, and in fig. 4, the direction approaching the central axis is referred to as inner, and the direction away from the central axis is referred to as outer, with reference to the vertical central axis of the plug contact 3. For any structure or component, the end or side thereof that is closer to the central axis is referred to as the inner end or inner end surface, the end or side thereof that is farther from the central axis is referred to as the outer end or outer end surface, and the left end surface of the conductive insert 31 may be referred to as the outer end surface and the right end surface may be referred to as the inner end surface, taking the conductive insert 31 on the left side in fig. 4 as an example.

In another embodiment, the external elastic mechanism may be used to apply force to the two conductive tabs 31, so as to clamp the two conductive tabs 31 to the main busbar 41. In this embodiment, the relationship between the shortest distance between the two conductive tabs 31 and the thickness of the main busbar 41 in the original state (when the elastic mechanism is not provided) is not limited, as long as the shortest distance between the two conductive tabs 31 can be smaller than the thickness of the main busbar 41 under the action of the elastic mechanism, and the main busbar 41 can be reliably clamped.

The elastic mechanism may specifically be a clip spring 32, but may be other members capable of generating elastic abutment force to the conductive tab 31. Taking the snap spring 32 as an example, as shown in fig. 3, the front and rear side walls of the conductive insert 31 near the end of the conductive member 2 may be provided with a clamping groove 314, so that the snap spring 32 may be clamped in the clamping groove 314 to complete the assembly of the snap spring 32. Referring to fig. 5, the clamping groove 314 may be a necking groove, that is, the notch of the clamping groove 314 has a small size and a large internal size, so that the clamping spring 32 installed in the clamping groove 314 is not easy to be separated from the notch. Alternatively, the conductive insert 31 may be provided with mounting holes, and then the clip 32 may be inserted through the mounting holes of the two conductive inserts 31, and the clip 32 may be mounted on the plug contact 3.

After the snap spring 32 is installed, two abutting ends of the snap spring 32 can respectively abut against outer end surfaces of the two conductive inserting sheets 31, so when the main busbar 41 is extruded into a gap between the two conductive inserting sheets 31, an outward thrust can be generated on the free ends of the conductive inserting sheets 31, and then the two abutting ends of the snap spring 32 act on the two abutting ends of the snap spring 32, and by means of elasticity of the two abutting ends of the snap spring 32, an inward reaction force can be generated on the two conductive inserting sheets 31, so that the conductive inserting sheets 31 are abutted against the main busbar 41, and reliable electrical connection between the conductive inserting sheets 31 and the main busbar 41 is guaranteed.

Further, referring to fig. 5, and referring to fig. 3, the outer end surfaces of the two conductive inserting pieces 31 may further be provided with receiving grooves 315, and two abutting ends of the clamping spring 32 may be respectively inserted into the corresponding receiving grooves 315. The arrangement is that the abutting end of the clamp spring 32 can be abutted against the same position of the conductive inserting sheet 31 all the time in the use process, so that the situation that the abutting end of the clamp spring 32 is deviated, moved or misplaced and the abutting end of the clamp spring 32 cannot be abutted against the outer end face of the conductive inserting sheet 31 due to the deviation, the movement or the misplacement of the abutting end of the clamp spring 32 can be avoided to a large extent; and this accommodation groove 315 still is equivalent to keeping away from the one end of electrically conductive piece 2 to jump ring 32 and carries out spacingly, and then the interval of accessible adjustment accommodation groove 315 and draw-in groove 314 for jump ring 32 supports tightly in draw-in groove 314 inside, with auxiliary positioning jump ring 32, thereby can prevent to a greater extent that jump ring 32 from deviating from the notch of draw-in groove 314.

In comparison, in the two embodiments, the elasticity of the conductive insert 31 is directly utilized to ensure the compaction of the conductive insert 31 and the main busbar 41, so that the structure of the plug contact 3 is simpler and the manufacturing cost is lower; the latter solution is more advantageous for ensuring a reliable compression of the conductive insert 31 with the main busbar 41, which is a preferred solution of the embodiment of the invention.

For a single plug contact 3, it is also possible to include a conductive tab 33, to which conductive tab 33 two conductive tabs 31 are connected and which can be fixed to the conductive element 2 by means of the conductive tab 33. In this case, the plug contact 3 may have an integral structure, the shape of which is substantially U-shaped, and both side plates of the U-shape are conductive tabs 31, and of course, the plug contact 3 may have other shapes, for example, may have an inverted convex shape with a lower opening in fig. 4, or may have an inverted trapezoid shape with a lower opening. The plug contact 3 may also be of a split type structure, i.e. it may comprise two conductive tabs 33, the two conductive tabs 33 being connected to respective conductive tabs 31, and the conductive tabs 31 being then fastened to the conductive member 2 by means of the respective conductive tabs 33. In the embodiment of the present invention, the integrated plug contact 3 is preferably used to simplify the installation structure of the plug contact 3 and the conductive member 2.

Taking integrated plug contact 3 as an example, during installation, the plug contact can further comprise a pressing plate 21, wherein the pressing plate 21 can be arranged on the end face of the conductive contact piece 33, which is away from the conductive piece 2, and the pressing plate 21 is arranged on the lower end face of the conductive contact piece 33, which is attached to the pressing plate 21, in view of fig. 4, a connecting hole is formed in the pressing plate 21, and a first peripheral connecting piece can sequentially pass through the conductive piece 2 and the conductive contact piece 33 and is connected with the connecting hole of the pressing plate 21 so as to press-connect and fix the conductive contact piece 33 to the conductive piece 2, and then the plug contact 3 and the conductive piece 2 are fixedly connected. The first connecting piece and the pressing plate 21 may be specifically in a threaded connection or in a riveting manner, and correspondingly, the first connecting piece may be a screw or a rivet; for ease of installation, the embodiment of the invention preferably employs screws to mate with the pressure plate 21 to secure the plug contact 3 to the conductive member 2.

The number of the connecting holes is preferably more than three, and the three connecting holes can be distributed in a triangular shape so as to ensure the reliable compression of the plug contact 3; when the number of the connecting holes is three or more, the connecting holes can be uniformly distributed on the pressing plate 21, and the uniformity of the stress of the conductive tab 33 can be improved. In practical application, taking the first connecting piece as an example, a screw is adopted, and a plurality of nuts can be adopted to replace the pressing plate 21, however, considering that the internal space of the plug contact 3 is limited, a certain time is required for installation by adopting the plurality of nuts, the scheme of the pressing plate 21 is preferably adopted in the embodiment of the invention, so that the assembly process of the adapter is simplified, and the assembly efficiency is improved.

As shown in fig. 3, the conductive insert 31 may further be provided with a slot 311 extending along the plugging direction, and the slot 311 may divide the conductive insert 31 into a first sheet 312 and a second sheet 313, so as to improve the breaking and arc extinguishing capability of the conductive insert 31, thereby ensuring the safety performance of the adapter provided by the present invention. Further, the slot 311 may be L-shaped, and the L-shaped transverse slit may be disposed away from the conductive member 2, so as to reduce the possibility of arc expansion, thereby improving the safety performance of the adapter to a greater extent.

It should be noted that the length and width of the slot 311 and the lengths of the L-shaped transverse slit and the L-shaped longitudinal slit are not limited in the embodiment of the present invention, and are specifically related to parameters such as the passing current of the plug contact 3, and may be set by those skilled in the art according to actual use requirements.

Based on the above arrangement of the slots 311, for a single plug contact 3, the number of the snap springs 32 may be two, and two abutting ends of each snap spring 32 may respectively abut against the outer end surfaces of two opposite first pieces 312 and two opposite second pieces 313, so as to ensure that each first piece 312 and each second piece 313 may reliably abut against the main busbar 41. Of course, even if the slots 311 are not present, two or more snap springs 32 may be disposed on the single plug contact 3 to enhance the effective abutment of the conductive insert 31 with the main busbar 41.

With continued reference to fig. 3, and with reference to fig. 4, the end portions (the lower end portions in the drawing) of the first and second pieces 312 and 313 away from the conductive member 2 may be gradually bent outwards along the direction away from the conductive member 2, i.e. the end portions of the plug contacts 3 away from the conductive member 2 form flares gradually expanding along the direction away from the conductive member 2, so as to facilitate the insertion of the plug contacts 3 into the main busbar 41.

Further, a connection board 5 may be further included, and the connection board 5 may be used to connect the housing 1 and the circuit breaker 6, so as to mount the circuit breaker 6 to the adaptor provided by the present invention.

As shown in fig. 2, the connection plate 5 may be a slot-type plate, one of which may be connected to the housing 1 and the other may be connected to the circuit breaker 6, of opposite side plates (upper and lower side plates in fig. 2). Specifically, the upper and lower side plates of the connection plate 5 may be provided with screw holes 51, and then the connection plate 5 may be fixed to the case 1 and the circuit breaker 6 by screws. More specifically, the length of the upper side plate may be longer, and the threaded hole 51 of the upper side plate may be provided at a portion exceeding the lower side plate in the length direction thereof, so that a larger avoiding gap may be provided below the upper side plate, so as to avoid damage to other structures inside the housing 1 caused by the tail portion of the screw screwed into and penetrating through the upper side plate to a greater extent; meanwhile, an avoidance hole 52 can be formed in the position, opposite to the threaded hole 51 formed in the lower side plate, of the upper side plate, the size of the avoidance hole 52 can be larger than that of the threaded hole 51 and the size of the head of a screw, when the screw is installed, the tail of the screw can penetrate through the avoidance hole 52 and is inserted into the threaded hole 51 of the lower side plate, and then screw operation tools such as a screwdriver can penetrate through the avoidance hole 52 and abut against the head of the screw inserted into the threaded hole 51 of the lower side plate so as to operate the screw.

Still further, the circuit breaker may further include a conductive post 22, and the conductive post 22 may be a copper post, and in an assembled state, two axial ends of the conductive post 22 may be connected to a wire inlet end of the circuit breaker 6 and the conductive member 2, so as to electrically connect the circuit breaker 6 and the adapter.

Specifically, the conductive post 22 may be provided with a through hole extending along an axial direction, and the peripheral second connecting member, such as a screw, a bolt, etc., may pass through the circuit breaker 6 and the through hole and be connected with the conductive member 2, so as to compress the wire inlet end of the circuit breaker 6 and the conductive member 2 on two axial ends of the conductive post 22 respectively, thereby ensuring connection reliability of the wire inlet end of the circuit breaker 6 and the conductive member 2.

It should be understood that the above-mentioned scheme of arranging the connection board 5 to connect the circuit breaker 6 with the adapter and arranging the conductive post 22 to connect the circuit breaker 6 with the adapter is merely an exemplary description of the embodiment of the present invention, and is not intended to limit the implementation range of the adapter provided by the present invention, and other manners of connecting and electrically connecting the circuit breaker 6 with the adapter may be adopted on the premise of satisfying the use function; for example, a flat plate type connection plate 5 may be used to connect the circuit breaker 6 and the housing 1 of the adapter at the same time, or even, the circuit breaker 6 and the housing 1 of the adapter may be directly connected by a connection member such as a screw, instead of the connection plate 5, or the wire inlet end of the circuit breaker 6 may be directly pressed against the conductive member 2 by a bolt, etc.

The following examples of the present invention will also describe the structure of the housing 1 of the adapter according to the above embodiments.

As shown in fig. 6 and 9, the circuit breaker 6 and the bus bar system 4 may be disposed on opposite end surfaces of the housing 1, respectively, and for convenience of description, an end surface of the housing 1, on which the circuit breaker 6 is attached (i.e., an installation end surface of the circuit breaker 6), may be referred to as a first end surface, an end surface of the housing 1, on which the bus bar system 4 is attached (opposite), may be referred to as a second end surface, and a wall surface of the housing 1 surrounding the plugging direction may be referred to as a peripheral wall surface.

The end surface of the housing 1, which is attached to the bus bar system 4, that is, the second end surface may be provided with a limiting pin 13, as shown in fig. 8, where the bus bar system 4 includes a bracket 42, a main bus bar 41 inserted in the bracket 42, and a fixing base plate 43 fixed on the bracket 42, and the adaptor provided by the present invention may be hung on the fixing base plate 43 of the bus bar system 4 through the limiting pin 13, so as to determine the installation position of the adaptor relative to the bus bar system 4, and then fix the adaptor on the fixing base plate 43 through a third connecting piece such as a fastening screw, so as to complete the fixed installation of the adaptor. By adopting the mounting structure which is positioned by the limiting pin 13 and then fixedly connected by the third connecting piece, on one hand, the mounting structure is more beneficial to finding the mounting position of the adapter; on the other hand, before the third connecting piece is installed, the adapter is positioned, and when the third connecting piece is installed, the adapter does not need to be supported, so that the installation process is easier.

In particular, in the embodiment of the present invention, the number of the limiting pins 13 is preferably two, and the two limiting pins 13 may be respectively disposed at two opposite angles of the second end surface, and then the fastening screws may be disposed at the other two opposite angles, so that the adapter can be reliably connected to the bus bar system 4 only by using a smaller number (two) of fastening screws, and the two fastening screws are disposed diagonally, which can ensure the reliable connection between the adapter housing 1 and the fixing base plate 43.

In the actual installation, the above-mentioned limiting pin 13 may be omitted, that is, a third connecting member such as a fastening screw may be directly used to fix the adapter to the bus bar system 4, and the reliable installation of the adapter may be achieved.

The peripheral wall surface of the shell 1 can be provided with a plurality of hand-held structures, and an operator can directly apply acting force to the hand-held structures so as to conveniently perform plugging operation, thereby realizing quick installation and disassembly of the adapter; meanwhile, the hand holding structure can meet the requirement of safe production, and can avoid electric shock accidents caused by the fact that an operator stretches fingers to the abutting position of the shell 1 and the bus system 4 to carry out buckling operation without applying force when pulling out the adapter. Specifically, the grip structure may be a handle or a projection provided on the peripheral wall surface of the housing 1, or may be a groove 12 provided on the peripheral wall surface of the housing 1.

Further, the contact part of the hand holding structure and the fingers of the operator can be provided with the prismatic or convex points and other touch parts so as to improve the touch feeling, and meanwhile, the operator can conveniently and accurately and quickly find the hand holding structure through the fingers so as to apply force.

The peripheral wall surface of the shell 1 surrounding the plugging direction can be further provided with an interface 11 for installing safety interlocking accessories so as to select customized safety interlocking accessories according to actual use requirements and meet the safety use requirements of the adapter. The interface 11 may be in a hole shape, a bar-shaped groove, or a combination of various forms, regardless of the form, as long as it can be matched with a safety interlocking accessory actually required to be installed.

The embodiment of the invention also provides an adapter assembly, which comprises the circuit breaker 6 and the adapter related to the embodiments, wherein the circuit breaker 6 is arranged on the adapter, the connection end of the conducting piece 2 in the adapter and the circuit breaker 6 is provided with a conducting column 22, and the circuit breaker 6 can be electrically connected with the conducting column 22.

Since the above-mentioned adaptor has the technical effects as described above, the adaptor assembly having the adaptor also has similar technical effects, and thus will not be described herein.

The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
