[0040] The existing ring network cabinet top-out connection bent busbar adopts the form of a section of cable + crimping terminals 200 at both ends. In order to avoid other lines, the cable will be forcibly bent from a straight line to achieve a side bend connection during actual use, which causes great stress on the cable. Based on the above technical problems, the present application provides a hard-bent busbar 100 and a top-out extended hard-bent busbar structure. By structurally optimizing the first conductive rod 110 in the hard-bent busbar 100, a certain distance is created between the main section 111 of the first conductive rod 110 and the connection end, thereby facilitating the avoidance of other lines. There is no need to forcibly bend the cable during actual installation, thereby avoiding the loosening of the joint 210 due to stress after the cable is installed.

[0041] Please refer to Figure 1 In the first aspect of the present application, a rigid-bend busbar 100 is provided, comprising a first conductive rod 110, a cable insulation layer 120 and a cable shielding layer 130; the first conductive rod 110 comprises a main section 111, an extension section 112 and a connecting end 113, the extension section 112 connects the main section 111 and the connecting end 113, and the extension section 112 is arranged obliquely on the same side of the main section 111; the cable insulation layer 120 is wrapped on the main section 111 and the extension section 112, and the cable shielding layer 130 is wrapped on the cable insulation layer 120.

[0042] The extension section 112 of the first conductive rod 110 is obliquely connected to the main section 111, so that the first conductive rod 110 itself is curved, which can meet certain busbar bending requirements in the ring network cabinet. Even if the cable needs to be further bent, the first conductive rod 110 will still be within a reasonable stress range. Therefore, the cable can be stably installed on the connector 210 without applying excessive torque to the connector 210, so as to prevent deformation of the connector 210 from causing creepage, breakdown, partial discharge instability, etc.

[0043] The cable insulation layer 120 and the cable shielding layer 130 can not only insulate and shield electromagnetic waves, but also increase the flexibility of the entire rigid-bend busbar 100, so that the rigid-bend busbar 100 can be further bent to meet the busbar bending requirements in the ring network cabinet. The two ends of the first conductive rod 110 form a connecting end 113, which can form a stable electrical connection with the crimping terminal 200.

[0044] It should be noted that the so-called cable insulation layer 120 and the cable shielding layer 130 need to be made of materials with relatively high flexibility to meet the toughness requirements of the hard-bend busbar 100. Rubber materials are generally used. In view of the fact that the cable insulation layer 120 needs to be insulated and the shielding layer needs to be conductive, the cable insulation layer 120 uses insulating silicone rubber, and the cable shielding layer 130 uses conductive silicone rubber. The first conductive rod 110 generally uses a metal material with excellent conductive properties, preferably copper.

[0045] In a further embodiment of the present application, a pair of extension sections 112 and connecting ends 113 are provided, and each connecting end 113 is connected to the corresponding extension section 112; the main section 111 and the extension section 112 are integrally formed, and the first conductive rod 110 has a curved structure; the angle formed by each extension section 112 and the main section 111 is the same, both of which are 130°-150°; along the radial center plane of the main section 111, the extension sections 112 and the connecting ends 113 on both sides of the center plane are symmetrically arranged.

[0046] A pair of connecting terminals 113 enhances the stability of the connection between the cable and other devices or systems, allowing both ends of the rigid-bend busbar 100 to be connected via the connecting terminals 113, reducing the risk of overall connection failure due to a single connection point failure. The main section 111 and extension section 112 are integrally formed, and the overall curved structure not only enhances the mechanical strength of the cable but also allows it to better adapt to complex wiring environments during installation. In particular, when wiring requires avoidance, it reduces internal stress concentration caused by bending or twisting, thereby extending the service life of the rigid-bend busbar 100.

[0047] Each extension section 112 forms the same angle with the main section 111, and the extension sections 112 and the connecting ends 113 on both sides of the center plane are symmetrically arranged, so that the structures on both sides of the rigid bend busbar 100 are the same, so that the connecting ends 113 at both ends can be connected to any crimping terminal 200, thereby improving the versatility of the rigid bend busbar 100; at the same time, the symmetrical arrangement of the first conductive rod 110 helps to achieve force balance. When the first conductive rod 110 is subjected to external force, the symmetrical design of the first conductive rod 110 can reduce the stress concentration caused by the offset load, thereby improving the service life and safety of the conductive rod. At the same time, since the stresses on the connecting ends 113 at both ends are consistent, that is, the reaction forces on the connectors 210 connected to the connecting ends 113 at both ends are consistent, the connectors 210 connected at both ends will not be loose at one end. Similarly, due to stress reasons, the entire rigid bend busbar 100 can also be symmetrically arranged along both sides of the center plane.

[0048] The angle formed by the extension section 112 and the main section 111 is between 130° and 150°, which can meet the needs of avoiding most lines, facilitate electrical connection in compact or complex environments, reduce space requirements, and prevent the angle deviation of the main section 111 relative to the extension section 112 from being too large, thereby affecting the strength of the connection between the main section 111 and the extension section 112, thereby ensuring the service life of the entire hard-bent busbar 100.

[0049] In a further embodiment of the present application, the cable shielding layer 130 partially protrudes radially to form an opening portion 131 and a ring portion 132, and the ring portion 132 is connected to the grounding wire 300; an opening 131A is formed on the opening portion 131, and the cable insulation layer 120 partially protrudes radially and the radial protrusion is arranged in the opening 131A.

[0050] The opening portion 131 and the ring portion 132 cooperate with each other to conduct static electricity on the cable insulation layer 120 and the cable shielding layer 130 and the leakage current of the entire hard-bent busbar 100 from the connecting wires. The radial direction refers to the direction from the center of the cable core (the cable core in this application is the first conductive rod 110) toward the cable insulation layer 120.

[0051] Please refer to Figure 2-Figure 4 The second aspect of the present application provides an ejection-extended rigid-bend busbar structure, comprising the rigid-bend busbar 100 and the crimping terminal 200 provided in the first aspect, the crimping terminal 200 comprising a joint 210 and a connecting assembly 230; the joint 210 is provided with a joint hole 210A and a connecting hole 210B that are interconnected, the rigid-bend busbar 100 passes through the joint hole 210A and the connecting end 113 is partially arranged in the connecting hole 210B; the connecting assembly 230 is inserted into the connecting hole 210B and passes through the connecting end 113 to connect the joint 210 and the rigid-bend busbar 100.

[0052] Insert the rigid bend busbar 100 from the joint hole 210A until the connecting end 113 of the rigid bend busbar 100 passes through the joint hole 210A and enters the connecting hole 210B, and then insert the connecting assembly 230 from the connecting hole 210B. At this time, the connecting assembly 230 will also pass through the connecting end 113, thereby limiting the rigid bend busbar 100 so that the rigid bend busbar 100 cannot freely escape from the joint hole 210A.

[0053] The crimping terminal 200 adopts a combined design of a connector 210 and a connecting assembly 230 to ensure a firm connection between the connecting end 113 of the rigid bend busbar 100 and the connector 210. Compared with traditional welding or threaded connections, it has higher connection strength and stability, and can effectively resist loosening or falling off caused by external factors such as vibration and impact, thereby enhancing the reliability of the entire electrical connection structure. At the same time, it can also form a tight electrical connection between the crimping terminal 200 and the rigid bend busbar 100, reducing contact resistance.

[0054] In a further embodiment of the present application, the connector 210 includes a connector insulation layer 212 and a connector shielding layer 211, and the connector shielding layer 211 is wrapped around the connector insulation layer 212; the cable insulation layer 120 at both ends is exposed outside the cable shielding layer 130, and the cable insulation layer 120 exposed outside the cable shielding layer 130 is completely arranged in the connector hole 210A and connected to the connector insulation layer 212, and the cable shielding layer 130 is connected to the connector shielding layer 211 and the connector insulation layer 212.

[0055] The joint insulation layer 212 effectively isolates the electrical connection between the inside of the joint 210 and the external environment, ensuring the safe operation of the electrical connection structure. At the same time, the close connection between the cable insulation layer 120 and the joint insulation layer 212 further enhances the overall electrical insulation performance and prevents current leakage and short circuit.

[0056] The connector shielding layer 211 is not only wrapped around the connector insulation layer 212, but is also tightly connected to the cable shielding layer 130, forming a continuous shielding layer structure, which effectively blocks the influence of external electromagnetic interference on signal transmission, while also reducing the radiation of internal signals to the external environment, thereby improving the electromagnetic compatibility and signal transmission quality of the entire electrical connection structure.

[0057] In a further embodiment of the present application, the connecting assembly 230 includes: a connecting seat 232, which is arranged at the connection point between the joint hole 210A and the connecting hole 210B, and the connecting end 113 is passed through the connecting seat 232; and a connecting member 231, which passes through the connecting seat 232 and the connecting end 113 to connect the joint 210 and the hard-bent busbar 100.

[0058] The connecting seat 232 is arranged at the connection point between the connector hole 210A and the connecting hole 210B, serving as a support and positioning structure for the connecting end 113, ensuring that the connecting end 113 can be accurately aligned and stabilized in a predetermined position during the insertion process, thereby preventing an unstable connection caused by position displacement or shaking.

[0059] Since the connector 210 itself is made of a flexible material, the connection seat 232 needs to provide a certain strength to ensure the stability of the connection between the connector 210 and the rigid-bend busbar 100 .

[0060] In a further embodiment of the present application, a cable trough 232A, a through-hole 232B and a through-hole 232C are provided on the connecting seat 232. The through-hole 232B connects the through-hole 232C and the cable trough 232A. The through-hole 232C and the connecting hole 210B are coaxially arranged. The connecting piece 231 passes through the connecting seat 232 from the through-hole 232C; the rigid bend busbar 100 is inserted into the cable trough 232A, and the connecting end 113 passes through the connecting seat 232 from the through-hole 232B.

[0061] In this solution, the cable trough 232A provides a precise insertion path and positioning space for the rigid bend busbar 100, ensuring the stability and accuracy of the cable during the connection process. The through hole 232B serves as a channel for the connecting end 113 to pass through, and is connected to the cable trough 232A, further guiding the connecting end 113 to accurately align with the connecting hole 210B, thereby reducing connection problems caused by position offset.

[0062] Please continue to refer to Figure 3-Figure 4 , Figure 4 The provided crimping terminal 200 is used to connect a hard-bent busbar 100. Figure 3 The provided crimping terminal 200 is used to connect two rigid-bend busbars 100 .

[0063] In a further embodiment of the present application, two rigid bend busbars 100 are provided, and two corresponding connector holes 210A are provided on the connector 210 to respectively connect to the corresponding rigid bend busbars 100; two corresponding through holes 232B and cable troughs 232A are provided on the connecting seat 232, and the two through holes 232B are spaced apart in the extension direction of the connecting hole 210B, and each cable is inserted into the corresponding cable trough 232A.

[0064] In this scheme, when a crimping terminal 200 connects two rigid-bend busbars 100, two corresponding joint holes 210A are provided on the joint 210. By arranging the two through holes 232B on the connecting seat 232 at intervals in the extension direction of the connecting hole 210B, the connecting ends 113 on the two rigid-bend busbars 100 can enter the connecting hole 210B at different positions. At this time, the connecting assembly 230 passes through the connecting ends 113 on the two rigid-bend busbars 100, thereby fixing the two rigid-bend busbars 100 on the crimping terminal 200 respectively.

[0065] Please refer to Figure 5 In a further embodiment of the present application, connection assembly 230 further includes: a fastening member, which is locked within connection base 232 and connected to connection member 231; a plug cover 234, which covers connection member 231; and a protective cap 235, which covers connection hole 210B to seal connection hole 210B. Both plug cover 234 and protective cap 235 provide protection, preventing dust and other foreign matter from entering connection hole 210B.

[0066] Please refer to Figure 6 In a further embodiment of the present application, the crimping terminal 200 also includes: a second conductive rod 240, electrically connected to the first conductive rod 110; a sleeve 250, the second conductive rod 240 is passed through the sleeve 250 and the connecting hole 210B; and a support member 220, the support member 220 is sleeved on the sleeve 250, and the connector 210 is arranged on the support member 220.

[0067] In this solution, the second conductive rod 240 and the sleeve 250 cooperate with each other to increase the height of the entire crimping terminal 200, making it easier to avoid other structures, thereby better realizing the spatial arrangement of the cable.

[0068] In a further embodiment, the support member 220 is also composed of a supporting shielding layer and a supporting insulating layer. The supporting shielding layer is wrapped on the supporting insulating layer. The supporting insulating layer forms a cavity, and the sleeve 250 is disposed in the cavity.

[0069] In a further embodiment, the material of the support insulation layer and the connector insulation layer 212 is the same as that of the cable insulation layer 120, and the material of the support shielding layer and the connector shielding layer 211 is the same as that of the cable shielding layer 130. The support shielding layer and the connector shielding layer 211 are also connected to the ground wire 300 to conduct static electricity on the support member 220 and the connector 210.

[0070] In a further embodiment, the sleeve 250 is inserted into the connecting hole 210B, and the sleeve 250 and the connecting member 231 are respectively inserted into the two ends of the connecting hole 210B. A limiting hole is also provided on the sleeve 250, and the limiting hole is coaxially arranged with the connecting hole 210B. When the connecting member 231 is inserted into the connecting hole 210B, it first passes through the end hole 113A of the connecting end 113 on the hard-bent busbar 100, and then is inserted into the limiting hole to cooperate with the fastener 233 to limit the connecting member 231.
