Therefore, the design of high-voltage busbar shapes is quite diverse and is tailored to specific needs. Summary of the Invention

[0004] The problem to be solved by the present invention is to provide a high-current elastic connector with a C-shaped support.

[0005] To solve the above problems, the present invention provides a high-current elastic connector with a C-shaped support. To achieve the above objectives, the technical solution adopted by the present invention to solve its technical problems is as follows: A high-current flexible connector with a C-shaped support includes: a C-shaped support comprising a C-shaped body, a radial notch formed between the two ends of the C-shaped body, and a plurality of outward protrusions on one side of the C-shaped support along the arc direction of the C-shaped body; each end of the C-shaped body having a through hole; a floating socket having an outwardly extending radially protruding edge on its outer wall; and a main socket located on the outer ring of the floating socket, the inner wall of the main socket having a circumferential groove; wherein the outer ring of the C-shaped support is assembled with the circumferential groove; one side of the outward protrusions contacts the outward protruding edge; and the distance from the outward protrusions to the center of the C-shaped support is less than the distance from the through hole to the center of the C-shaped support.

[0006] As a further improvement of the present invention, the C-shaped support member has a number of recesses on the opposite side of the side where the outer convex bulge is located.

[0007] As a further improvement of the present invention, the inner wall of the concave pit is composed of a first convex curved surface and a first flat bottom surface, and the outer wall of the convex bulge is composed of a second convex curved surface and a second flat bottom surface, wherein the first flat bottom surface and the second flat bottom surface are parallel to each other; the first convex curved surface is the side surface of the inner wall of the concave pit, and the second convex curved surface is the side surface of the outer wall of the convex bulge; the area of ​​the first flat bottom surface is smaller than the area of ​​the second flat bottom surface.

[0008] As a further improvement of the present invention, the diameter of the circle corresponding to the root of the convex bulge is larger than the diameter of the through hole.

[0009] As a further improvement of the present invention, one end of the main socket has an annular groove, and the circumferential groove is recessed in the side wall of the annular groove; the inner diameter of the annular groove is larger than the outer diameter of the outer protrusion, and there is a gap between the inner wall of the annular groove and the outer edge of the outer protrusion, and the axial projection of the through hole intersects with the gap.

[0010] As a further improvement of the present invention, the axial length of the main socket is less than the axial length of the floating socket, and the two ends of the floating socket are exposed from the two ends of the main socket.

[0011] As a further improvement of the present invention, the outer bulge and the through hole are located on both sides of the extended center line of the C-shaped support.

[0012] As a further improvement of the present invention, the central angle corresponding to the radial notch is in the range of 40° to 50°, and the central angle between two adjacent outward convex bulges is in the range of 15° to 25°.

[0013] As a further improvement of the present invention, both ends of the C-shaped body are straight cut edges. Of the two extended lines of the straight cut edges, one intersects the center of the C-shaped support, and the other does not intersect the center of the C-shaped support.

[0014] As a further improvement of the present invention, the C-shaped support is made of an integral elastic metal material.

[0015] The beneficial technical effects of using the high-current flexible connector with C-shaped support of this application are: This technical solution is a quick-connect busbar connection structure design that can be used in high-voltage electrical fields. The C-shaped support has a radial notch and a retractable structure. After retraction, it can be assembled with the circumferential groove of the main socket. The overall assembly operation is convenient, and the assembly method of the outer ring and the circumferential groove can provide stable positioning of the C-shaped support, ensuring the reliability of the overall assembly structure of the connector.

[0016] The C-shaped support has several outward protrusions along the arc direction, which contact the outward protrusion of the floating socket to form a multi-point contact conductive structure. The multi-point contact effectively improves the stability of current flow and can meet the requirements of high current loads.

[0017] The C-shaped support has through holes at both ends, and the distance from the outer bulge to the center of the circle is differentiated by the distance from the through hole to the outer bulge. The tightness of the C-shaped support can be adjusted by inserting a tool into the through hole, thereby controlling the contact pressure between the outer bulge and the outer edge. It also facilitates the disassembly and assembly of the connector and makes it easier for later maintenance.

[0018] The elastic support structure of the C-shaped support, combined with the precise contact between the outward bulge and the outward bulge edge, makes it easier to control the lateral insertion and extraction force of the connector through structural dimensions, adapting to the insertion and extraction operation requirements in different usage scenarios and improving the adaptability of the connector.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to specific embodiments: To achieve the objectives of this invention, a high-current elastic connector with a C-shaped support includes: as follows Figure 1 As shown, the C-shaped support 1 includes a C-shaped body 11, with a radial notch 12 formed between the two ends of the C-shaped body 11, as... Figure 4 , Figure 6 As shown, one side of the C-shaped support 1 has several outwardly protruding bulges 14 along the arc direction of the C-shaped body 11, and each end of the C-shaped body 11 has a through hole 15. Figure 7 As shown, the floating socket 2 has an outwardly extending radially protruding edge 22 on its outer wall. The main socket 3 is located on the outer ring of the floating socket 2, and its inner wall has a circumferential groove 32. The outer ring of the C-shaped support 1 is assembled with the circumferential groove 32. The outwardly protruding bulge 14 contacts one axial end face of the outwardly protruding edge 22. The radial distance from the outwardly protruding bulge 14 to the center of the C-shaped support 1 is less than the radial distance from the through hole 15 to the center of the C-shaped support.

[0023] The beneficial effects of adopting the above technical solution are: the overall process of the C-shaped support 1 is simple. Using needle-nose pliers to shrink the C-shaped support 1, after assembly, the C-shaped support 1 plays the role of supporting the main body structure, and the outward convex 14 forms contacts, and multiple contacts are conducive to current flow.

[0024] Multi-point contact ensures good contact stability, a simple overall structure, and easy control of lateral insertion and extraction forces. Suitable for assembled and embedded injection molded terminals, multiple contact positions can meet high current loads.

[0025] Lateral thrust can be controlled by size. When it is necessary to disassemble or adjust the C-shaped support 1, a sharp clamp or other tool can be inserted into the through hole 15 to adjust the tightness, that is, to adjust the curvature of the C-shaped support 1, which is equivalent to adjusting the outer diameter of the C-shaped support 1. Changing the unstable riveting structure to an assembly structure is beneficial to the stability of product performance. There is also no riveting imbalance, and disassembly and assembly can be achieved with only a small lateral thrust.

[0026] In some other embodiments of the present invention, the C-shaped support 1 has a plurality of recesses 13 on the opposite side of the side where the outer convex 14 is located.

[0027] Each convex 14 corresponds to an inner recess 13 along the axial direction. The convex 14 and the inner recess 13 are formed by stamping. The inner recess 13 is formed by pressing one side of the C-shaped support 1. The plastic deformation displacement of the material forms the convex 14.

[0028] The beneficial effects of adopting the above technical solution are as follows: A recess 13 is provided on the opposite side of the C-shaped support 1 corresponding to the outer convex 14, which can be formed in one step by stamping, simplifying the processing technology. The recess 13 gives the outer convex 14 better elastic deformation capability, ensuring stable contact with the outer convex edge 22, further enhancing electrical conductivity reliability.

[0029] like Figure 2 As shown, in some embodiments of the present invention, the inner wall of the recess 13 is formed by a first convex surface 131 and a first flat bottom surface 132, and the outer wall of the convex bulge 14 is formed by a second convex surface 141 and a second flat bottom surface 142, wherein the first flat bottom surface 132 and the second flat bottom surface 142 are parallel to each other. The first convex surface 131 corresponds to the side surface of the inner wall of the recess 13, and the second convex surface 141 corresponds to the side surface of the outer wall of the convex bulge 14. The area of ​​the first flat bottom surface 132 is smaller than the area of ​​the second flat bottom surface 142.

[0030] The beneficial effects of adopting the above technical solution are: this structure makes the contact surface flat, the contact resistance low, the curved part helps to guide positioning, and the area difference ensures that the contact pressure is moderate, the contact is stable and not easy to wear.

[0031] like Figure 1 As shown, in some other embodiments of the present invention, the diameter of the circle corresponding to the root of the convex bulge 14 is larger than the diameter of the through hole 15.

[0032] In addition, such as Figure 3 As shown, the diameter of the circle corresponding to the root of the convex bulge 14 is greater than the convex height of the convex bulge 14.

[0033] The beneficial effects of adopting the above technical solution are: the diameter of the circle corresponding to the root of the convex bulge 14 is larger than the diameter of the through hole 15, ensuring that the root of the convex bulge 14 has sufficient strength and is not easily deformed. At the same time, the through hole 15 is located in a relatively outer ring position, which facilitates the insertion of tools to apply force and adjust, making the overall force distribution more reasonable.

[0034] In other embodiments of the present invention, one end of the main socket 3 has an annular groove 31, and a circumferential groove 32 is recessed into the side wall of the annular groove 31. The inner diameter of the annular groove 31 is larger than the outer diameter of the outer protrusion 22, and there is a gap between the inner wall of the annular groove 31 and the outer edge of the outer protrusion 22, such as... Figure 8 , Figure 9 As shown, the axial projection of the through hole 15 intersects with the gap.

[0035] The opening of the circumferential groove 32 faces radially inward, and the opening of the annular groove 31 is axial.

[0036] In addition, such as Figure 9 As shown, the opening edge of the annular groove 31 has inner serrations 34, and several inner serrations 34 are arranged in a ring array.

[0037] In addition, such as Figure 7 As shown, one end of the outer wall of the main socket 3 has an annular stop 33 extending radially outward.

[0038] The beneficial effects of adopting the above technical solution are: the through hole 15 is exposed in the gap, which makes it convenient for the tool to operate and adjust the C-shaped support 1 from the axial direction, while the annular groove 31 provides a accommodating space to avoid interference.

[0039] like Figure 7 As shown, in some other embodiments of the present invention, the axial length of the main socket 3 is less than the axial length of the floating socket 2, and the two ends of the floating socket 2 are exposed from the two ends of the main socket 3 respectively.

[0040] In addition, such as Figure 7 As shown, the floating socket 2 has an axially penetrating cavity 23 inside. The two ends of the inner wall of the cavity 23 have radially inwardly extending inner convex edges 21, and the radial extension length of the outer convex edge 22 is greater than the radial extension length of the inner convex edge 21.

[0041] The advantages of adopting the above technical solution are: it facilitates the connection of the floating socket 2 with other components, the exposed ends increase the connection flexibility and adapt to different installation needs, and the support of the main socket 3 is concentrated in the middle, which does not affect the plugging at both ends.

[0042] like Figure 1 As shown, in some other embodiments of the present invention, the outer bulge 14 and the through hole 15 are located on both sides of the extended center line of the C-shaped support 1.

[0043] The convex bulge 14 is relatively close to the inner edge of the C-shaped support 1, and the through hole 15 is relatively close to the outer edge of the C-shaped support 1.

[0044] The beneficial effect of adopting the above technical solution is that it makes the through hole 15 as far out as possible, thereby ensuring that the through hole 15 is located at the position of the gap.

[0045] like Figure 1As shown, in some other embodiments of the present invention, the central angle corresponding to the radial notch 12 is the first central angle β, the angle range of the first central angle β is 40° to 50°, and the central angle corresponding to the two adjacent outward convex bulges 14 is the second central angle θ, the angle range of the second central angle θ is 15° to 25°.

[0046] In terms of preferred degrees, the central angle corresponding to the radial notch 12 is twice the central angle between two adjacent convex bulges 14. Specifically, the central angle corresponding to the radial notch 12 is 43°, and the central angle between two adjacent convex bulges 14 is 21°.

[0047] The beneficial effects of adopting the above technical solution are: this angle range ensures that the C-shaped support 1 has sufficient elastic deformation capacity and can maintain shape stability when shrinking, and the spacing of the outer protrusion 14 is moderate, ensuring uniform multi-point contact and sufficient contact area to meet the requirements of large current passage.

[0048] like Figure 1 As shown, in some other embodiments of the present invention, both ends of the C-shaped body 11 are straight cut edges, and one of the extension lines of the two straight cut edges intersects the center of the C-shaped support 1, while the other does not intersect the center of the C-shaped support 1.

[0049] Figure 1 Using the dashed line to connect the straight cut edge to the center of the C-shaped support 1, it can be seen that one of the straight cut edges does not completely coincide with the direction of the corresponding dashed line.

[0050] The beneficial effects of adopting the above technical solution are: this asymmetrical cut design allows the deformation direction of the C-shaped support 1 to be controlled under stress, avoiding jamming, and facilitating positioning during assembly, thus improving assembly efficiency. It also facilitates breaking the symmetry, making it easier for personnel to quickly distinguish the front and back sides.

[0051] In other embodiments of the present invention, the C-shaped support 1 is made of an integral elastic metal material.

[0052] The beneficial effects of adopting the above technical solution are: the C-shaped support 1 is made of an integral elastic metal material, which ensures the structural strength and conductivity. The elastic metal gives it good elasticity and conductivity, making it suitable for high current applications. Moreover, the integral molding process is simple and the cost is low.

[0053] In one implementation, several convex ridges are added axially to the inner ring of the C-shaped support 1. These tiny convex ridges form auxiliary line contact or surface contact with the side of the outer convex edge 22 of the floating socket 2, which not only further increases the current conduction path, but also plays a damping and anti-loosening role in a vibration environment. At the same time, a chamfer is set at the edge of the through hole 15 to form a guide slope, which facilitates automatic centering when the tool is inserted, reduces operational deviation, and makes the adjustment more precise and smooth.

[0054] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
