A wiring module

Abstract

The present invention provides a wiring module. The bus bar clamp has a bolt pressing plate assembly disposed on the upper part of the contact member and a clamping member disposed on the lower part of the contact member and adapted to clamp the incoming bus bar. The bolt pressing plate assembly and the contact member relatively form a wire clamping cavity adapted to clamp the outgoing cable. The bus bar clamp is connected to the base through a guiding structure and can be slidably connected to the incoming bus bar through a coupling structure. The bus bar clamp has a first position where its bolt pressing plate assembly abuts against the contact member and a second position where, under the action of the incoming bus bar and the base, it can move upward relative to the contact member. During assembly, first insert the incoming bus bar into the slot on the base. During the insertion process, under the action of the incoming bus bar and the guiding structure of the base, the bus bar clamp can move upward relative to the contact member, thereby driving the bolt pressing plate assembly to move upward relative to the contact member, thus expanding the space of the wire clamping cavity to facilitate the insertion of the outgoing cable. The above structure makes the assembly process simpler, time-saving and labor-saving, and reduces the labor cost.

Description

Technical Field

[0001] The present invention relates to the technical field of low-voltage enclosed busbar systems, and particularly to a wiring module. Background Art

[0002] Wiring modules are widely used in electrical equipment to connect incoming busbars and outgoing cables. As Figures 9 - 11 shown, the wiring module includes a housing, and a busbar clamp 02 disposed in the housing 01 for clamping the incoming busbar and the outgoing cable. The busbar clamp 02 includes a busbar clamp body 021, a bolt pressing plate assembly 022 disposed above it, and a connecting plate 023 disposed in the middle thereof. The connecting plate 023 is fixed to the housing 01. The connecting plate 023 and the bolt pressing plate assembly 022 located above it relatively form a first wire clamping cavity 03 suitable for installing the outgoing cable, and the connecting plate 023 and the clamping plate portion 04 located below it relatively form a second wire clamping cavity 05 suitable for installing the incoming busbar. During assembly, the bolt pressing plate assembly 022 is tightened to move the busbar clamp body 021, so as to tightly connect the outgoing cable, the incoming busbar and the connecting plate 023.

[0003] The defect of the above solution is that before assembly, due to the self-gravity of the busbar clamp body 021, the side plates on both sides thereof abut against the connecting plate 023, resulting in a relatively small space of the first wire clamping cavity 03 between the bolt pressing plate assembly 022 and the connecting plate 023 (as Figure 12 shown), which is not enough to put the outgoing cable. Therefore, the assembler needs to lift the busbar clamp body 021 from the bottom upwards with one hand (as Figure 13 shown) to make the space of the first wire clamping cavity 03 larger, insert the outgoing cable into the first wire clamping cavity 03 from the side with the other hand, and then insert the incoming busbar into the second wire clamping cavity 05. The above assembly process is cumbersome, time-consuming and laborious, increasing the labor cost. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the existing technology, such as cumbersome assembly process, time-consuming and laborious, so as to provide a wiring module with simple and fast assembly.

[0005] To this end, the present invention provides a wiring module, comprising a base, a contact member, and a bus bar clamp. The base is provided at its bottom with a slot for inserting an incoming line bus bar; the contact member is fixedly provided on the base and is located in the middle of the clamping cavity of the bus bar clamp; the bus bar clamp has a bolt pressing plate assembly provided above the contact member, and a clamping member provided below the contact member and adapted to clamp the incoming line bus bar. The bolt pressing plate assembly and the contact member oppositely form a wire clamping cavity adapted to clamp an outgoing cable. The bus bar clamp is connected to the base through a guiding structure and can be slidably connected to the incoming line bus bar through a coupling structure. The bus bar clamp has a first position where the bolt pressing plate assembly thereof abuts against the contact member, and a second position where, under the action of the incoming line bus bar and the base, it can move upward relative to the contact member.

[0006] The coupling structure is a mating inclined surface provided on the bus bar clamp and slidably cooperating with the incoming line bus bar. The mating inclined surface is inclined downward and backward along the insertion direction of the incoming line bus bar.

[0007] The guiding structure is a slide rail structure provided between the bus bar clamp and the base.

[0008] The slide rail structure is adapted to make the moving direction of the bus bar clamp perpendicular to the moving direction of the incoming line bus bar.

[0009] The slide rail structure includes two chutes and two sliders. The two chutes are respectively provided on two opposite inner side surfaces of the base and extend in the vertical direction; the two sliders are respectively provided on both sides of the bus bar clamp and are adaptively connected to the corresponding chutes.

[0010] Above the base, there is a cover plate adapted to shield the bus bar clamp, and a locking structure adapted to lock the cover plate and the base is also included.

[0011] The locking structure includes two first jacks, two second jacks, and a locking member. The two first jacks are provided on the cover plate; the two second jacks are provided on the base and are correspondingly arranged with the two first jacks. At least one limiting hole is formed on the inner wall of the second jack; the locking member has a main body portion that can abut against the cover plate, and elastic arms respectively provided on both sides of the main body portion and perpendicular to the main body portion. A limiting block adapted to be adaptively connected to the limiting hole is provided on the outer side surface of the elastic arm.

[0012] On the outer side surface of the elastic arm, there is also an inverted tooth that can be oppositely arranged with the bottom wall of the first jack. The inverted tooth is provided above the limiting block.

[0013] A groove for inserting a screwdriver to pry up the locking member is formed on the main body portion.

[0014] The contact is fixed to the base by screws.

[0015] The technical solution of the present invention has the following advantages:

[0016] 1. For the wiring module provided by the present invention, the busbar clamp has a bolt pressing plate assembly provided on the upper part of the contact and a clamping member provided on the lower part of the contact and adapted to clamp the incoming busbar. The bolt pressing plate assembly and the contact relatively form a wire clamping cavity adapted to clamp the outgoing cable. The busbar clamp is connected to the base through a guiding structure and can be slidably connected to the incoming busbar through a coupling structure. The busbar clamp has a first position where its bolt pressing plate assembly abuts against the contact, and a second position where it can move upward relative to the contact under the action of the incoming busbar and the base. During assembly, first insert the incoming busbar into the slot on the base. During the insertion process, under the action of the incoming busbar and the guiding structure of the base, the busbar clamp can move upward relative to the contact, thereby driving the bolt pressing plate assembly to move upward relative to the contact, thus expanding the space of the wire clamping cavity for clamping the outgoing cable, so as to facilitate the insertion of the outgoing cable. Compared with the prior art where the assembler needs to lift the busbar clamp upward from below with one hand and insert the outgoing cable into the first wire clamping cavity from the side with the other hand, there is no need for two-handed operation at the same time, the assembly process is simpler, time-saving and labor-saving, and the labor cost is reduced.

[0017] 2. For the wiring module provided by the present invention, the coupling structure is a mating inclined surface provided on the busbar clamp and slidably cooperating with the incoming busbar. The mating inclined surface is inclined downward and backward along the insertion direction of the incoming busbar. The inventor cleverly sets the mating inclined surface, so that under the action of the guiding structure of the base and the lateral thrust of the incoming busbar, the busbar clamp can convert the lateral thrust of the incoming busbar into an acting force for driving the busbar clamp to move upward. The mating inclined surface has the advantage of simple structure.

[0018] 3. For the wiring module provided by the present invention, the slide rail structure is adapted to set the moving direction of the busbar clamp perpendicular to the moving direction of the incoming busbar. The above slide rail structure can prevent the busbar clamp from shifting left and right when moving upward, so as to facilitate the insertion of the outgoing cable, thus improving the assembly efficiency.

[0019] 4. For the wiring module provided by the present invention, the slide rail structure includes two chutes and two sliders. The two chutes are respectively arranged on two opposite inner side surfaces of the base and extend along the vertical direction; the two sliders are respectively arranged on both sides of the busbar clamp and are adaptively connected to the corresponding chutes. The mutually cooperating chutes and sliders have the advantage of simple structure.

[0020] 5. The wiring module provided by the present invention, the locking structure includes two first jacks, two second jacks and a locking member. The two first jacks are arranged on the cover plate; the two second jacks are arranged on the base and are correspondingly arranged with the two first jacks. At least one limiting hole is formed on the inner wall of the second jack; the locking member has a main body portion that can abut against the cover plate, and elastic arms respectively arranged on both sides of the main body portion and perpendicular to the main body portion. The outer side surface of the elastic arm is provided with a limiting block that can be adaptively connected with the limiting hole. The above locking structure makes the connection between the cover plate and the base more firm, not easy to separate, and has a simple structure.

[0021] 6. The wiring module provided by the present invention, the outer side surface of the elastic arm is also provided with reverse teeth that can be oppositely arranged with the bottom wall of the first jack. The reverse teeth are arranged above the limiting block. In this way, after the cover plate and the base are separated, the locking member is still connected to the cover plate, which has the advantage that the locking member is not easy to lose.

[0022] 7. The wiring module provided by the present invention, the main body portion is formed with a groove for inserting a screwdriver to pry up the locking member, so that it is convenient to pry up the locking member, separate the cover plate from the base, and the disassembly is quick and convenient.

[0042] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] Embodiment

[0044] This embodiment provides a wiring module, as Figure 1 and 2 shown, which includes a base 1, a contact 2, a bus bar clamp 3, a cover plate 6 and a locking member 7.

[0045] The base 1, as Figure 1 , 4 , 5 shown, has a slot 11 at its bottom for inserting an incoming line bus bar, and an installation step 15 located below the slot 11. There is a protrusion 16 on the installation step for preventing the incoming line bus bar from disengaging after insertion. Two chutes 12 are respectively provided on two inner sides of the base 1 arranged oppositely. The chutes 12 extend in the vertical direction. Two second jacks 13 are provided on the inner side surface of the base 1, and two limiting holes 14 are formed on the inner wall of the second jacks 13.

[0046] The contact 2, as Figure 2 shown, is fixedly provided on the base 1 by screws 21 and is located in the middle of the clamping cavity of the bus bar clamp 3. Anti-slip patterns in the shape of wavy lines are provided on the upper and lower sides of the contact 2.

[0047] The busbar clamp 3 has a first position in which the bolt pressure plate assembly 4 abuts against the contact member 2, and a second position in which the bolt pressure plate assembly 4 can move upward relative to the contact member 2 under the action of the incoming busbar and the base 1, such as Figure 1 , 2 As shown in Figures 3, 6 and 7, the busbar clamp 3 has a busbar clamp body 34, a bolt pressure plate assembly 4 arranged above the busbar clamp body, and a clamping member 31 below the busbar clamp body suitable for clamping the incoming busbar. A threaded hole is provided on the top of the busbar clamp body 34, and the bolt pressure plate assembly 4 includes a bolt 41 inserted into the threaded hole, and a pressure plate 42 arranged at the bottom of the bolt. The pressure plate and the contact member 2 are relatively formed to form a clamping cavity 5 suitable for clamping the outgoing cable. The busbar clamp 3 is provided with a mating inclined surface 32 that can slidably cooperate with the incoming busbar. The mating inclined surface 32 is arranged to be tilted downward and backward along the insertion direction of the incoming busbar. Slide blocks 33 are respectively provided on both sides of the busbar clamp 3, and the slide blocks 33 are adaptively connected with the corresponding slide grooves 33. Before assembly, as shown in FIG. Figure 2 As shown, the pressure plate 42 of the bolt pressure plate assembly 4 abuts against the contact member 2. Figure 2 Insert the busbar into the slot 11 in the direction of the arrow, and the incoming busbar slides with the matching inclined surface 32, driving the busbar clamp 3 to move vertically upward along the slide groove 12 of the base 1 to Figure 3 In the second position shown, since the bolt 41 is fixedly connected to the busbar clamp 3, the pressing plate 42 is driven to move upward, so that the space of the wire clamp cavity 5 becomes larger to facilitate the insertion of the outgoing cable.

[0048] It should be noted that the weight of the incoming busbar is much greater than the weight of the busbar clamp 3. Therefore, when the incoming busbar is fully inserted into the slot and when the hand removes the thrust on the incoming busbar, the busbar clamp 3 will not fall down, but will remain in the second position, thereby facilitating the insertion of the outgoing cable into the clamp cavity 5. In addition, the protrusion 16 on the installation step 15 can also limit the assembly position of the incoming busbar.

[0049] Cover plate 6, such as Figure 1 , 4 As shown in , 5 , it is arranged above the base 1 and is suitable for shielding the busbar clamp 3 . Two first plug holes 61 corresponding to the second plug holes 13 are arranged on the inner side surface of the cover plate 6 .

[0050] Locking member 7, such as Figure 1 , 4As shown in FIGS. 5 and 8, it has a main body portion 71 that can abut against the cover plate 6, and elastic arms 72 that are respectively provided on both sides of the main body portion 71 and are perpendicular to the main body portion 71. A limiting block 73 that can be adaptively connected to the limiting hole 14 is provided on the outer side surface of the elastic arm 72. A reverse tooth 74 that can be oppositely arranged with respect to the bottom wall 62 of the first jack 61 is also provided on the outer side surface of the elastic arm 72. The reverse tooth 74 is provided above the limiting block 73. A groove 75 for inserting a screwdriver to pry up the locking member 7 is formed in the main body portion 71.

[0051] As a transformable embodiment, the coupling structure is a mating arc surface provided on the busbar clamp 3 and slidably engaged with the incoming busbar.

[0052] As a transformable embodiment, the incoming busbar is formed with a mating inclined surface that can be slidably engaged with the busbar clamp 3 and drive the busbar clamp 3 to move upward.

[0053] For the wiring module provided by the present invention, the busbar clamp 3 has a bolt pressing plate assembly 4 provided on the upper part of the contact member 2, and a clamping member provided on the lower part of the contact member 2 and adapted to clamp the incoming busbar. The bolt pressing plate assembly 4 and the contact member 2 relatively form a wire clamping cavity 5 adapted to clamp the outgoing cable. The busbar clamp 3 is connected to the base 1 through a guiding structure and can be slidably connected to the incoming busbar through a coupling structure. The busbar clamp 3 has a first position where its bolt pressing plate assembly 4 abuts against the contact member 2, and a second position where it can move upward relative to the contact member 2 under the action of the incoming busbar and the base 1. During assembly, first insert the incoming busbar into the slot on the base. During the insertion process, the busbar clamp 3 can move upward relative to the contact member 2 under the action of the guiding structure of the incoming busbar and the base 1, thereby driving the bolt pressing plate assembly 4 to move upward relative to the contact member, thus expanding the space of the wire clamping cavity 5 for clamping the outgoing cable to facilitate the insertion of the outgoing cable. Compared with the prior art where the assembler needs to lift the busbar clamp upward with one hand from below and insert the outgoing cable into the first wire clamping cavity from the side with the other hand, there is no need for two-handed operation, the assembly process is simpler, time-saving and labor-saving, and the labor cost is reduced.

[0054] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
