[0022] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. However, those skilled in the art can understand that, in the embodiments of the present application, many technical details are proposed in order to make the reader better understand the present application. However, the technical solutions claimed by the present application can be implemented even without these technical details and based on various changes and modifications of the following embodiments.

[0023] Referring to Figures 1 to 6 , the first embodiment of the present application relates to a laminated busbar 10. The core of the present embodiment is that the laminated busbar 10 comprises: a busbar body 11, a first end head 12 arranged at a first end of the busbar body 11, and a second end head 13 arranged at a second end of the busbar body 11; the busbar body 11 comprises a first conductive layer 111, a first insulating substrate 112, and a second conductive layer 113 stacked along a first direction X; the first end head 12 comprises: a first conductive member 121 and a second conductive member 122 connected to the first conductive layer 111 and the second conductive layer 113, respectively; the first conductive member 121 comprises: a first conductive part 1211 extending from the first conductive layer 111 along the first direction X, and a first extension part 1212 extending from the first conductive part 1211 in a direction away from the second end; the second conductive member 122 comprises: a second conductive part 1221 extending from the second conductive layer 113 along the first direction X, and a second extension part 1222 extending from the second conductive part 1221 in a direction away from the second end; the first extension part 1212 and the second extension part 1222 are arranged opposite to each other in a second direction Y perpendicular to the first direction X.

[0024] Since the first conductive part 1211 extends from the first conductive layer 111 in the first direction X, and the first direction X is the stacking direction of the busbar body 11, the first conductive part 1211 is bent by 90° once with respect to the extension direction of the busbar body 11. Since the first extension part 1212 extends from the first conductive part 1211 in a direction away from the second end, the first extension part 1212 is bent by 90° once with respect to the extension direction of the first conductive part 1211. After two bends, the orientation of the first conductive part 121 is rotated by 90°. Based on similar reasons, the orientation of the second conductive part 122 is also rotated by 90°. Since the first extension part 1212 and the second extension part 1222 are arranged opposite to each other in the second direction Y perpendicular to the first direction X, the first extension part 1212 and the second extension part 1222 can be directly plugged with the adapter 30 as the positive and negative poles, respectively, in the direction connecting the first end and the second end of the busbar body 11, without the need for conversion via the PCB board, simplifying the structure of the power input system, improving the space utilization, and reducing the equipment cost.

[0025] The implementation details of the stacked busbar 10 of the present embodiment will be specifically described below. The following content is only the implementation details provided for the convenience of understanding, and is not essential for implementing the present solution.

[0026] The first conductive layer 111 and the second first conductive layer 111 can be positive and negative conductive copper bars, respectively. The first conductive layer 111 and the first conductive part 121 can be made of conductive material in one piece. The second conductive layer 113 and the second conductive part 122 can be made of conductive material in one piece.

[0027] Referring to Figure 2 Specifically, the busbar body 11 can further include a second insulating substrate 114 surrounding the first conductive layer 111 and arranged in the same layer as the first conductive layer 111, and a third insulating substrate 115 surrounding the second conductive layer 113 and arranged in the same layer as the second conductive layer 113. The first insulating substrate 112 extends between the second insulating substrate 114 and the third insulating substrate 115. The second insulating substrate 114 and the third insulating substrate 115 insulate and support the first conductive layer 111 and the second conductive layer 113, respectively.

[0028] Optionally, the fourth insulating substrate 116 can be arranged on the side of the first conductive layer 111 away from the first insulating substrate 112, and the fifth insulating substrate 117 can be arranged on the side of the second conductive layer 113 away from the first insulating substrate 112, so as to avoid problems such as short circuit caused by exposure of the first conductive layer 111 and the second conductive layer 113. That is, the combination part of the busbar body 11 and the first end 12 is not covered by insulating material, and the remaining part is treated with insulating sealing, thereby improving safety.

[0029] In addition, PP plates (polypropylene plates) can be provided between the fourth insulating substrate 116 and the first conductive layer 111, between the first conductive layer 111 and the first insulating substrate 112, between the first insulating substrate 112 and the second conductive layer 113, and between the second conductive layer 113 and the fifth insulating substrate 117, so as to ensure the impact resistance of the busbar body 11.

[0030] See Figure 3 , Figure 4 In this embodiment, the first conductive portion 1211 includes: a first portion 1211a extending from the edge of the first conductive layer 111 along a first direction X, a second portion 1211b extending from the first portion 1211a by bending, and a third portion 1211c extending from the second portion 1211b along the first direction X. The first extension 1212 extends from the third portion 1211c in a direction away from the second end. The busbar body 11 and the second portion 1211b are located on the same side of the first portion 1211a. The second extension 1222 includes: from the second conductive portion 1211a... The fourth portion 1222a extending away from the second end and away from the busbar body 11, and the fifth portion 1222b extending away from the fourth portion 1222a in a direction away from the second end, are located directly above the second extension 1222 in a second direction Y perpendicular to the first direction X (the second direction Y can be the direction Z perpendicular to the first direction X and perpendicular to the line connecting the first end and the second end). In practical applications, the shapes of the first conductive element 121 and the second conductive element 122 can be integrally pressed together by an insulating substrate.

[0031] This arrangement results in a larger distance between the first conductive part 1211 and the second conductive part 1221 in the second direction Y, and a larger distance between the first extension part 1212 and the second extension part 1222 in the second direction Y, ensuring that there is sufficient space between the first conductive member 121 and the second conductive member 122, which are respectively the positive and negative poles, to achieve isolation.

[0032] It is understandable that the busbar body 11 and the second part 1211b can also be located on both sides of the first part 1211a. Correspondingly, the fourth part 1222a extends from the second conductive part 1221 in a direction away from the second end and close to the busbar body 11. In the second direction Y perpendicular to the first direction X, the first extension 1212 is located directly below the second extension 1222. This arrangement can also achieve a similar technical effect, which will not be elaborated here.

[0033] In actual application, in order to avoid the first conductive part 121 and the second conductive part 122 being exposed, which leads to short circuit or safety hazard, the laminated busbar 10 can further include an insulating insert 14, the insulating insert 14 includes a first through hole and a second through hole, the first through hole is used for accommodating the first conductive part 121, the second through hole is used for accommodating the second conductive part 122, the first conductive part 121 is inserted from one side of the first through hole and connected with the connector through the other side of the first through hole, and the second conductive part 122 is inserted from one side of the second through hole and connected with the connector through the other side of the second through hole.

[0034] Optionally, the insulating insert 14 can be provided with a first positioning part 15, the first positioning part 15 is used for covering the first through hole and the second through hole after the first conductive part 121 and the second conductive part 122 are respectively installed in the first through hole and the second through hole, specifically, the first positioning part 15 is used for clamping the second conductive layer 113 in the insulating insert 14, the insulating insert 14 can be provided with two second positioning parts 16, the two second positioning parts 16 hold the second part 1211b from both sides along the direction Z of the line connecting the first end and the second end, thereby improving the stability of the first conductive part 121 and the second conductive part 122 installed in the insulating insert 14.

[0035] That is, after assembly, the insulating insert, the first conductive part 121 and the second conductive part 122 form a socket end, which can directly connect to the adapter 20 to realize conduction with the external circuit.

[0036] Referring to Figure 5 , Figure 6 Specifically, the second end head 13 includes a third conductive part 131 extending from the first conductive layer 111 along the first direction X and a fourth conductive part 132 extending from the second conductive layer 113 along the first direction X, the third conductive part 131 and the fourth conductive part 132 are located in the same plane, and the power end head or other end head can be directly covered on the third conductive part 131 and the fourth conductive part 132 to realize electrical connection.

[0037] In order to realize the installation and fixation of the second end head 13, the second end head 13 can further include an insulating fixing seat 17, the insulating fixing seat 17 includes oppositely arranged first and second surfaces, and the third conductive part 131 and the fourth conductive part 132 are fixed on the first surface. In actual application, the third conductive part 131 and the fourth conductive part 132 can be provided with a fixing part 18, the insulating fixing seat 17 is provided with at least two through holes, and the fixing part 18 is in interference fit with the through hole, so as to fix the third conductive part 131 and the fourth conductive part 132 on the insulating fixing seat 17.

[0038] Optionally, multiple ribs 19 are provided around each fastener 18 on the first surface, and the fastener 18 is interference-fitted with the multiple ribs 19. The fastener 18 can be a press-fit nut. That is, firstly, holes are made in the third conductive element 131 and the fourth conductive element 132, and the holes are riveted to the press-fit nut by a pressing process. Then, the other end of the press-fit nut is pressed into the through hole of the insulating fixing base 17. At this time, the multiple ribs 19 are interference-fitted with the fastener 18, which ensures the firmness of the third conductive element 131 and the fourth conductive element 132 installed on the insulating fixing base 17.

[0039] In other words, after assembly, the insulating fixing base 17, the third conductive element 131, and the fourth conductive element 132 form a terminal block, which can directly attach cables or similar copper busbars to realize the internal circuit conduction and current shunting.

[0040] Compared with the prior art, this embodiment has a first end 12 which is a socket end that can be directly plugged into the adapter 20 to achieve communication with external circuits. The second end 13 is a terminal block that can be directly attached to cables or similar copper busbars to achieve internal circuit communication and current splitting. It does not require conversion through components such as PCB boards, and the connection method is simple and the operation direction is straightforward.

[0041] The second embodiment of the present invention relates to a power input connection component, such as... Figures 7 to 13 As shown, it includes: the stacked busbar 10 as described above, and an adapter 20 that is plugged into the first end 12 of the stacked busbar 10. Furthermore, the technical effects of this embodiment are similar to those of the first embodiment, and will not be repeated here.

[0042] The following is a detailed description of the implementation details of the stacked busbar 10 in this embodiment. The following content is only for the convenience of understanding and is not necessary for implementing this solution.

[0043] See Figure 7Specifically, the adapter 20 includes: a base 201, a first contact 202 and a second contact (not shown) located within the base 201. The first contact 202 includes: a 2021 for connecting to the first extension 1212, and a second contact 2022 extending from the first contact 2021 by bending. The second contact includes: a third contact for connecting to the second extension 1222, and a fourth contact extending from the third contact by bending. Furthermore, the first contact 2021 and the third contact are arranged in parallel, the second contact 2022 extends away from the third contact, and the fourth contact extends away from the first contact 2021. This arrangement changes the orientation of the first contact 202 and the second contact, thereby enabling better cooperation with the plug 40 of the external circuit. Through three bends (two bends of the first end 12 and one bend of the first contact 202 and the second contact), the contact method / direction is continuously changed, improving operational convenience and increasing space utilization.

[0044] In practical applications, the adapter 20 also includes: a panel seal 204, a cover plate 205, two spring clips 206, and two shielding plates 207. The base 201 is mounted on the housing. The panel seal 204 is directly mounted on the base 201 to achieve a seal on the housing. The stacked busbar is installed inside the housing. One spring clip 206 is positioned and fixed to the first contact 202 via a protrusion 31 (protruding inwards from the spring clip 206), a groove 42, and a limiting slot 43. The first contact 202 is inserted into a pre-drilled mounting hole in the base 201 and limited by the groove 41. The installation method of the other spring clip 206 and the second contact is similar and will not be described further here. After the first contact 202 and the second contact are installed, the cover plate 205 is inserted and fixed to the base 201 via a first retaining structure 21 and a second retaining structure 22. Two shielding plates 207 are inserted into the other end of the base 201 and fixed and positioned via a groove 61 and a protrusion 62. The first contact and the third contact are both connected to the plug 40 at one end and to the stacked busbar at the other end to realize the conduction of the circuit.

[0045] This configuration ensures the connector's excellent reliability, meets the reliability requirements in small spaces, greatly reduces the usable space, and at the same time achieves the goal of saving installation and design costs.

[0046] See Figure 8In this embodiment, the power input connection assembly may further include a plug 40 for connecting to the adapter 20. The plug 40 may include a housing 401 and a locking assembly 402 located within the housing 401 for fixing the conductive terminal 4024. Specifically, the plug 40 may further include an interface seal 403, a wrench 404, a spring 405, a button 406, an elastic claw 407, a cable seal 408, and a nut 409. The interface seal 403 is installed in the plastic groove 44' of the housing 401. The wrench 404 is connected to the housing 401 through the through hole 21' and the protrusion 41', and rotates around the protrusion 41'. The locking assembly 402 is installed into the cavity of the housing 401 by the guide groove 31' and is fixed by a side unlocking buckle. The spring 405 and the button 406 are installed sequentially from right to left into the button groove 43' of the housing 401, serving to unlock and engage the wrench 404. The cable seal 408 is inserted into the elastic claw 407, with the bottom surface of the elastic claw 407 coinciding with the top surface 82 of the boss on the cable seal 408. The protrusion 72 is engaged in the groove 81, and then it is inserted into the housing 401, secured by the protrusion 71 and the groove 42'. Finally, the nut 409 is screwed into the thread on the right end of the housing 401. The hook of the wrench 404 engages with the bosses on both sides of the base 201 of the adapter 20, completing the connection between the two.

[0047] See Figures 9 to 12 The wire-locking assembly 402 includes an outer base 4021, an inner base 4022, and a wire-pressing device 4023. The wire-pressing device 4023 is used to press the conductive terminal 4024 vertically. The inner base 4022 is a closed structure with a first opening for inserting the wire-pressing device 4023 and the conductive terminal 4024. The outer base 4021 is a closed structure with a second opening for inserting the inner base 4022. After the inner base 4022 is inserted into the outer base 4021 through the second opening, the inner wall of the outer base 4021 covers the first opening. Since the outer base 4021 adopts an integral fitting structure, the risk of cracking caused by excessive torque can be eliminated, improving product reliability. At the same time, since the outer base 4021 adopts a fully enclosed form, the inner base 4022 is inserted into the outer base 4021 to form a complete wire-locking assembly 402, avoiding the risk of lightning strike breakdown caused by poor fastening of the split structure.

[0048] To prevent the inner base 4022 from coming out of the second opening, a limiting part can be provided near the second opening. After the inner base 4022 is inserted into the outer base 4021 through the second opening, the limiting part can limit the inner base 4022, thereby ensuring the reliability of the locking assembly 402.

[0049] The wire pressing device 4023 includes a wire pressing frame 4023a, at least one screw 4023b passing through the wire pressing frame 4023a, and a pressing plate 4023c fixed to the tail of the screw 4023b. The conductive terminal 4024 is sandwiched between the wire pressing frame 4023a and the pressing plate 4023c.

[0050] Optionally, the wire clamp 4023a is provided with at least one first through hole and at least one second through hole. The screw 4023b located in the first through hole is used to hold the end of the conductive terminal 4024, and the screw 4023b located in the second through hole is used to adjust the distance between the wire clamp 4023a and the clamping plate 4023c. That is, the screw 4023b located in the first through hole is to confirm whether the conductive terminal 4024 (i.e., the cable) is inserted in place, and the screw 4023b located in the second through hole is to ensure the reliability of the crimping. The use of the double screw 4023b wire clamping structure can further ensure the firmness of the cable crimping on the basis of ensuring that the cable is inserted in place, preventing various hidden dangers caused by cable falling off, poor contact, etc., and improving the reliability of the power connector.

[0051] Specifically, the conductive terminal 4024 includes a positive terminal and a negative terminal. The end of the positive terminal is bent away from the negative terminal, and / or the end of the negative terminal is bent away from the positive terminal to form a supporting portion. The screw 4023b located in the first through hole is used to support the supporting portion. This arrangement changes the contact method between the conductive terminal 4024 and the screw 4023b from a clip to an insert, which facilitates the crimping of the screw 4023b.

[0052] In other words, in this embodiment, the wire locking assembly 402 comprises four screws 4023b, four clamping plates 4023c, two wire clamping frames 4023a, two conductive terminals 4024 (i.e., positive and negative terminals), an inner base 4022, and an outer base 4021. The screws 4023b move in the up-down direction. After being inserted into the wire clamping frames 4023a, the tail of the screws 4023b is riveted to the clamping plates 4023c, and then the conductive terminals 4024 are inserted from left to right. After assembly, the entire assembly is inserted into the inner base 4022 from bottom to top, with the 41” inserting into the 51” for positioning. The assembled inner base 4022 is then inserted into the outer base 4021 from right to left. The first guide groove 91, the second guide groove 92, and the third guide groove 93 are guided and fitted together by the first rib 94, the second rib 95, and the third rib 96, achieving stable, effective, and reliable assembly, ultimately forming the wire-locking assembly 402. The screw 4023b is inserted from below the inner base 4022, effectively utilizing product space. Furthermore, because the outer base 4021 adopts an integral, fitted structure, it avoids the risk of cracking due to the inner base 4022's weak unilateral structure being unable to withstand large torques when tightening the screw 4023b, thus reducing the width dimension.

[0053] In other words, the inner base 4022 is a cavity component with limiting slots and guide slots on the bottom and sides; the outer base 4021 is a cavity component with limiting and guide ribs on the bottom and sides; the screw 4023b is a conductor used to fix the conductive terminal 4024 (i.e., the wire conductor part) and apply torque to the wire clamping frame 4023a; the wire clamping frame 4023a is a cavity that carries the conductive terminal 4024, mainly accommodating the conductive terminal 4024, screw 4023b and wire, and bearing the torque of the screw 4023b, serving as the cable contact area; the conductive terminal 4024 is a stamped part, mainly serving to connect the front-end adapter 20 and the rear-end wire. When using this adapter 20 to connect the plug 40 to the stacked busbar, the plug 40 can be directly inserted into the adapter 20, which has the advantages of simple operation, low cost and small structural size. At the same time, it can also be arbitrarily expanded as a CBB module, which is in line with the application trend of integrated and miniaturized supporting equipment.

[0054] See Figure 13 In practical applications, the power input connection assembly may further include a protective cover 50 for connection to the adapter 20. The adapter 20 includes a connection port for electrical connection to an external line, and the protective cover 50 covers the connection port. The protective cover 50 is used to prevent the adapter 20 from being exposed and short-circuited when it is not connected to the plug 40.

[0055] In order to fix the protective cover 50 to the adapter 20, a wrench 501 can be provided on the protective cover 50 and a retaining part is provided on the adapter 20. The wrench 501 is retained on the retaining part to facilitate the removal and installation of the protective cover 50. Specifically, the protective cover 50 is provided with at least two connecting parts 502. The protective cover 50 is connected to the wrench 501 through the connecting parts 502 and can rotate around the center of the line connecting the at least two connecting parts 502.

[0056] To facilitate the storage of the protective cover 50 when not in use and to prevent it from being lost, the protective cover 50 is provided with a pull strap 503 and a hanging hole 504. When the protective cover 50 is not in use, it can be fixed to the housing of the adapter 20 using the hanging hole 504 for easy access. Specifically, the protective cover 50 may also be provided with a protrusion 505, and the pull strap 503 is provided with a fixing hole 506. The pull strap 503 is connected to the protective cover 50 via the fixing hole 506 and the protrusion 505.

[0057] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes in form and detail may be made without departing from the spirit and scope of the present invention.
