Technical Field

[0001] The invention relates to the field of electrical connectors, and in particular to a quick-plug high-voltage busbar connection structure. Background Art

[0002] Busbar is a multi-layer composite structure connecting bar. This connecting bar adopts advanced composite materials and technology, has excellent electrical and mechanical properties, and can meet the needs of high power, high efficiency and high reliability in the field of new energy. As the "highway" of power transmission, high-voltage busbar can carry large current and ensure stable and efficient transmission of power to various electrical equipment. In the power system, high-voltage busbar also plays the role of structural support to ensure the stability and safety of the entire distribution system.

[0003] The shapes of high-voltage busbars are various, the most common ones are straight bar, arc, U-shaped, etc. The size of the high-voltage busbar is determined by factors such as current load, voltage level and heat dissipation requirements. Therefore, the shape design of high-voltage busbars is relatively rich, and the design will be detailed according to specific needs. Summary of the invention

[0004] The problem to be solved by the present invention is to provide a quick-insertion high-voltage busbar connection structure, which can be used for high-voltage electrical connection. The rolled spring sheet brings good elastic clamping force and has low processing cost.

[0005] In order to solve the above problems, the present invention provides a quick-plug high-voltage busbar connection structure. In order to achieve the above purpose, the technical solution adopted by the present invention to solve its technical problems is:

[0006] A quick-plug high-voltage busbar connection structure comprises: a rolled spring sheet, comprising a plurality of axial connecting strips and axial cantilever strips alternately arranged at intervals along the circumferential direction, wherein the two ends of the axial connecting strip in the length direction are integrally connected to the two axial ends of the rolled spring sheet, and only one end of the axial cantilever strip in the length direction is integrally connected to one axial end of the rolled spring sheet; a socket sleeve, assembled with the outer ring of the rolled spring sheet, the inner wall of the socket sleeve is provided with two inner convex edges protruding radially inward, the two axial ends of the rolled spring sheet respectively abut against the inner convex edges, and the inner convex edges can limit the longest axial dimension of the rolled spring sheet; the inner diameter dimensions of the rolled spring sheet corresponding to the middle parts of the axial connecting strip and the axial cantilever strip are smaller than the inner diameter dimensions of the rolled spring sheet corresponding to the two ends of the axial connecting strip and the axial cantilever strip; the rolled spring sheet is made of an integral conductive elastic material.

[0007] The beneficial effects of adopting the above technical solution are: the technical solution is a quick-insertion busbar connection structure design, which can be used in the high voltage field. The rolled spring is inserted into the external rod and elastically clamps the external rod, and plays the role of electrical connection and current transmission.

[0008] First, the maximum axial dimension of the coiled spring is limited, and any longitudinal section of the coiled spring is equivalent to an elastic arch bridge structure. The middle part of the inner wall of the coiled spring is in squeeze contact with the external rod, but the axial end of the coiled spring is fixed, which forces the middle part of the inner wall of the coiled spring to maintain an elastic state of radially inward arching, maintaining the ability to elastically clamp the external rod when it is inserted.

[0009] Secondly, the elastic forces of the axial connecting bar and the axial cantilever bar are different. The axial cantilever bar is a cantilever structure, which is easier to swing elastically than the axial connecting bar. The axial cantilever bar weakens the hardness, so the axial connecting bar and the axial cantilever bar are matched with each other to allow the rolled spring to obtain a suitable elastic clamping force.

[0010] Finally, both the axial connecting bar and the axial cantilever bar can contact with the external rod. From a microscopic point of view, the contact surface is not a simple line contact, so it is suitable for use in the high voltage field. In addition, the entire coiled spring is also easy to stamp and process, and the cost is low.

[0011] As a further improvement of the present invention, a U-shaped cutting slit penetrates the coiled spring piece, and the coiled spring piece portion half-surrounded by the U-shaped cutting slit forms an axial cantilever strip; and the ends of all the axial cantilever strips face the same axial direction of the coiled spring piece.

[0012] The beneficial effect of adopting the above technical solution is that the axial cantilever strip can be relatively formed by punching out the U-shaped cutting seam, and the shape characteristics of the rolled spring sheet facilitate its production by stamping and blanking.

[0013] As a further improvement of the present invention, the axial cantilever bar is bent in an arc shape, and the axial cantilever bar is divided into a widened portion and a narrowed portion according to different widths, and one end of the narrowed portion is the root of the axial cantilever bar.

[0014] The beneficial effect of adopting the above technical solution is that the narrowed portion weakens the structural strength of the root of the axial cantilever bar, which facilitates the adaptive elastic swing of the axial cantilever bar.

[0015] As a further improvement of the present invention, the axial cantilever bar also has a stamped protrusion extending radially outward, and the other side of the axial cantilever bar corresponding to the stamped protrusion is also radially recessed with a stamped pit, and the stamped protrusion and the stamped pit overlap radially; the stamped protrusion and the stamped pit are located in the widened part of the axial cantilever bar.

[0016] The beneficial effect of adopting the above technical solution is that due to the characteristics of the stamping process, the stamping protrusions and the stamping pits are naturally formed together.

[0017] As a further improvement of the present invention, each axial connecting strip includes a pair of root oblique sections and a pair of middle oblique sections, the two middle oblique sections are connected to each other at an obtuse angle, and the root oblique section is also connected to the adjacent middle oblique section at an obtuse angle; along the axis in one direction, a root oblique section, a middle oblique section, a middle oblique section, and a root oblique section of the axial connecting strip are connected in sequence to form a W shape; a radially outward positive angle is formed at the junction of the two middle oblique sections, and a radially inward positive angle is formed at the junction of the root oblique section and the adjacent middle oblique section.

[0018] The beneficial effect of adopting the above technical solution is that the W-shaped wavy shape of the axial connecting strip, from a local microscopic point of view, facilitates more contact positions and more contact areas between the middle part of the axial connecting strip and the rod inserted into the coiled spring outside, thereby improving the stability of the elastic assembly.

[0019] As a further improvement of the present invention, the rolled spring leaf has a first dividing seam extending axially therethrough; the rolled spring leaf has C-shaped rings at both ends along the axial direction, one end of the root of the axial cantilever bar is integrally connected to the C-shaped ring, and the two ends of the axial connecting bar are respectively integrally connected to the two C-shaped rings; the junction of the axial connecting bar, the axial cantilever bar and the C-shaped ring has a radial convex point extending radially outward.

[0020] The beneficial effects of adopting the above technical solution are: the rolled spring is not a complete closed loop, but can be stamped and bent from a flat piece, which controls the process cost. In addition, the radial convex point facilitates the extrusion assembly of the rolled spring and the socket sleeve.

[0021] As a further improvement of the present invention, the C-shaped ring is further penetrated by a positioning hole; both ends of the coiled spring along the axial direction are further axially recessed with notches facing each other, and the notches and the first separation seam are distributed on both sides of the axis of the coiled spring.

[0022] The beneficial effect of adopting the above technical solution is that the positioning holes and notches can facilitate the positioning of the rolled spring during its own stamping production stage or during the assembly stage with the socket set, thereby ensuring the accuracy of processing and assembly.

[0023] As a further improvement of the present invention, the socket sleeve includes a floating socket and a main socket, the main socket is located on the outer ring of the floating socket; the inner convex edge is located on the inner wall of the floating socket, and the outer wall of the floating socket has an outer convex edge extending radially outward; the outer wall of the main socket has an annular stop extending radially outward.

[0024] The beneficial effect of adopting the above technical solution is that the socket sleeve is not a separate independent component, and the floating socket and the main socket have the possibility of floating and moving between the two components, which can accommodate millimeter-level deviations of accessories and has high applicability.

[0025] As a further improvement of the present invention, a retaining spring is provided between the floating socket and the main socket, and the inner wall of the main socket has a circumferential groove that is engaged with the retaining spring; the retaining spring is C-shaped, and a second separation gap is formed between the two ends of the retaining spring along the circumferential direction; one side of the retaining spring is protruding with a plurality of axial convex points, and the axial convex points are in contact with one side of the outer convex edge.

[0026] The beneficial effects of adopting the above technical solution are: the C-shape of the circlip is to ensure that it has a slightly expanded or contracted elastic margin, so as to fine-tune its inner diameter. The mature circlip structure has more contact points, that is, more axial convex points, smaller contact impedance, and is easy to assemble.

[0027] The floating socket is fixed by a retaining spring structure, which has lower production cost, more controllable size and higher production efficiency than the original riveting structure.

[0028] The circlip and rolled spring use an assembly process, which has a simpler structure and more controllable size than riveting.

[0029] As a further improvement of the present invention, a spring contact finger is provided between the floating socket and the main socket, and the main socket has an annular groove for accommodating the spring contact finger; the spring contact finger and the retaining spring are respectively located on both sides of the outer convex edge, and the spring contact finger contacts one side of the outer convex edge.

[0030] The beneficial effect of adopting the above technical solution is that the transfer structure adopts spring contact fingers to increase the number of contact points, obtain smaller contact impedance and softer contact pressure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The present invention is further described in detail below in conjunction with specific embodiments:

[0044] In order to achieve the purpose of the present invention, a quick-plug high-voltage busbar connection structure includes: a rolled spring 1, including a plurality of axial connecting bars 12 and axial cantilever bars 13 arranged alternately and spaced along the circumferential direction, the two ends of the axial connecting bar 12 in the length direction are integrally connected to the two axial ends of the rolled spring 1, and only one end of the axial cantilever bar 13 in the length direction is integrally connected to one axial end of the rolled spring 1; a socket sleeve, assembled with the outer ring of the rolled spring 1, the inner wall of the socket sleeve has two inner convex edges 21 protruding radially inward, the two axial ends of the rolled spring 1 respectively abut against the inner convex edges 21, and the inner convex edges 21 can limit the longest axial dimension of the rolled spring 1; the inner diameter size of the rolled spring 1 corresponding to the middle part of the axial connecting bar 12 and the axial cantilever bar 13 is smaller than the inner diameter size of the rolled spring 1 corresponding to the two ends of the axial connecting bar 12 and the axial cantilever bar 13; the rolled spring 1 is made of an integrated conductive elastic material.

[0045] The beneficial effect of adopting the above technical solution is: this technical solution is a quick-insert busbar connection structure design, which can be used in the field of high voltage electricity. The coiled spring is inserted into the external rod and elastically clamps the external rod, and plays the role of electrical connection and current transmission. First, the maximum axial size of the coiled spring is limited, and any longitudinal section of the coiled spring is equivalent to an elastic arch bridge structure. The middle part of the inner wall of the coiled spring is in compression contact with the external rod, but the axial end of the coiled spring is fixed, which forces the middle part of the inner wall of the coiled spring to maintain an elastic state of radially arching inward, and maintains the ability to elastically clamp the external rod when inserted. Secondly, the elastic forces of the axial connecting strip and the axial cantilever strip are different. The axial cantilever strip is a cantilever structure, which is easier to swing elastically than the axial connecting strip. The axial cantilever strip has the effect of weakening hardness, so the axial connecting strip and the axial cantilever strip are matched with each other, so that the coiled spring can obtain a suitable elastic clamping force. Finally, both the axial connecting bar and the axial cantilever bar can contact with the external rod. From a microscopic point of view, the contact surface is not a simple line contact, so it is suitable for use in the high voltage field. In addition, the entire coiled spring is also easy to stamp and process, and the cost is low.

[0046] like Figure 5 As shown, in other embodiments of the present invention, a U-shaped cutting slit 14 passes through the coiled spring 1, and the portion of the coiled spring 1 half-surrounded by the U-shaped cutting slit 14 forms an axial cantilever bar 13; the ends of all the axial cantilever bars 13 face the same axial direction of the coiled spring 1.

[0047] The beneficial effect of adopting the above technical solution is that the axial cantilever strip can be relatively formed by punching out the U-shaped cutting seam, and the shape characteristics of the rolled spring sheet facilitate its production by stamping and blanking.

[0048] In some other embodiments of the present invention, the axial cantilever bar 13 is curved, and is divided into a widened portion 132 and a narrowed portion 131 according to different widths, and one end of the narrowed portion 131 is the root of the axial cantilever bar 13 .

[0049] The width of the narrowed section 131 is smaller than the width of the widened section 132 .

[0050] The beneficial effect of adopting the above technical solution is that the narrowed portion weakens the structural strength of the root of the axial cantilever bar, which facilitates the adaptive elastic swing of the axial cantilever bar.

[0051] like Figure 4 , Figure 5As shown, in some other embodiments of the present invention, the axial cantilever bar 13 also has a stamped protrusion 134 extending radially outward, and the other side of the axial cantilever bar 13 corresponding to the stamped protrusion 134 is also radially recessed with a stamped pit 133, and the stamped protrusion 134 and the stamped pit 133 overlap radially; the stamped protrusion 134 and the stamped pit 133 are located in the widened portion 132 of the axial cantilever bar 13.

[0052] The two sides of the punching protrusion 134 and the punching concave 133 are cut off from the axial cantilever bar 13 , that is, each punching protrusion 134 or punching concave 133 has two parallel cut seams of equal length.

[0053] The beneficial effect of adopting the above technical solution is that due to the characteristics of the stamping process, the stamping protrusions and the stamping pits are naturally formed together.

[0054] In other embodiments of the present invention, each axial connecting strip 12 includes a pair of root oblique sections 121 and a pair of middle oblique sections 122, the two middle oblique sections 122 are connected to each other at an obtuse angle, and the root oblique section 121 is also connected to the adjacent middle oblique section 122 at an obtuse angle; along the axis in one direction, a root oblique section 121, a middle oblique section 122, a middle oblique section 122, and a root oblique section 121 of the axial connecting strip 12 are connected in sequence to form a W shape; the junction of the two middle oblique sections 122 forms a radially outward positive angle, and the junction of the root oblique section 121 and the adjacent middle oblique section 122 forms a radially inward positive angle.

[0055] The inner diameter of the rolled spring leaf 1 at the junction of the two middle oblique sections 122 is smaller than the inner diameter of the rolled spring leaf 1 at the middle of the axial cantilever strip 13 .

[0056] The junction between the two middle oblique sections 122 is transitioned through a rounded corner, and the junction between the root oblique section 121 and the adjacent middle oblique section 122 is transitioned through a rounded corner.

[0057] The beneficial effect of adopting the above technical solution is that the W-shaped wavy shape of the axial connecting strip, from a local microscopic point of view, facilitates more contact positions and more contact areas between the middle part of the axial connecting strip and the rod inserted into the coiled spring outside, thereby improving the stability of the elastic assembly.

[0058] In other embodiments of the present invention, the rolled spring leaf 1 has a first axially penetrating separation gap 11; the rolled spring leaf 1 has C-shaped rings 18 at both ends along the axial direction, one end of the root of the axial cantilever bar 13 is integrally connected to the C-shaped ring 18, and both ends of the axial connecting bar 12 are respectively integrally connected to the two C-shaped rings 18; the junction of the axial connecting bar 12, the axial cantilever bar 13 and the C-shaped ring 18 has a radial convex point 15 extending radially outward.

[0059] The beneficial effects of adopting the above technical solution are: the rolled spring is not a complete closed loop, but can be stamped and bent from a flat piece, which controls the process cost. In addition, the radial convex point facilitates the extrusion assembly of the rolled spring and the socket sleeve.

[0060] In some other embodiments of the present invention, the C-shaped ring 18 is further penetrated by a positioning hole 16 ; the two ends of the coiled spring 1 along the axial direction are further axially recessed with notches 17 , and the notches 17 and the first separation gap 11 are distributed on both sides of the axis of the coiled spring 1 .

[0061] The positioning hole 16 is rectangular.

[0062] The beneficial effect of adopting the above technical solution is that the positioning holes and notches can facilitate the positioning of the rolled spring during its own stamping production stage or during the assembly stage with the socket set, thereby ensuring the accuracy of processing and assembly.

[0063] In other embodiments of the present invention, the socket sleeve includes a floating socket 2 and a main socket 3, wherein the main socket 3 is located on the outer ring of the floating socket 2; the inner convex edge 21 is located on the inner wall of the floating socket 2, and the outer wall of the floating socket 2 has an outer convex edge 22 extending radially outward; the outer wall of the main socket 3 has an annular stop 33 extending radially outward.

[0064] The floating socket 2 and the main socket 3 may be made of insulating material.

[0065] The beneficial effect of adopting the above technical solution is that the socket sleeve is not a separate independent component, and the floating socket and the main socket have the possibility of floating and moving between the two components, which can accommodate millimeter-level deviations of accessories and has high applicability.

[0066] like Figure 7 As shown, in some other embodiments of the present invention, a retaining spring 5 is provided between the floating socket 2 and the main socket 3, and the inner wall of the main socket 3 has a circumferential groove 32 that is engaged with the retaining spring 5; the retaining spring 5 is C-shaped, and a second separating gap 53 is formed between the two ends of the retaining spring 5 along the circumferential direction; one side of the retaining spring 5 is protruded with a plurality of axial convex points 52, and the axial convex points 52 are in contact with one side of the outer convex edge 22.

[0067] The first separation gap 11 and the second separation gap 53 have the same meaning, both of which destroy the complete closed loop shape. The main body of the clamping spring 5 is a C-shaped plate 51, and a plurality of axial convex dots 52 are arranged on the C-shaped plate 51 at equal intervals.

[0068] The convex shapes of the radial convex dots 15 and the axial convex dots 52 are both hemispherical or smaller than hemispherical.

[0069] The beneficial effects of adopting the above technical solution are: the C-shape of the retaining spring is to ensure that it has a slightly expanded or contracted elastic margin, so as to fine-tune its inner diameter. The mature retaining spring structure has more contacts, that is, more axial convex points, smaller contact impedance, and is easy to assemble. The retaining spring structure is used to fix the floating socket, which has lower production costs, more controllable dimensions, and higher production efficiency than the original riveted structure. The retaining spring and the rolled spring leaf use an assembly process, which is simpler in structure and more controllable in size than the riveted structure.

[0071] The spring contact finger 4 is a coil spring in the shape of a closed ring as a whole, that is, it has a circular profile as a whole, but is a coil spring.

[0072] The beneficial effect of adopting the above technical solution is that the transfer structure adopts spring contact fingers to increase the number of contact points, obtain smaller contact impedance and softer contact pressure.

[0073] like Figure 1 As shown, the annular stop 33 of the main body socket 3 contacts the plate-shaped material 6, and the plate-shaped material 6 is provided with a plurality of main body sockets 3. The central axial through space of the rolled spring sheet 1 is used for the rod-shaped material 7 to pass through and be fixed.

[0074] To facilitate the display of internal results, Figure 1 The two rolled springs 1 in the figure only show one rod-shaped material 7. The rod-shaped material 7 is a copper rod material.

[0075] like Figure 3 As shown, the portion of the rolled spring 1 that is not in direct contact with the floating socket 2 forms a first radial gap 8, which provides space for the radially outward elastic retreat of the rolled spring 1 when the rolled spring 1 contacts the rod-shaped material 7.

[0076] like Figure 3 As shown, there is also a second radial gap 9 between the floating socket 2 and the main socket 3 , and the second radial gap 9 provides space for radial micro-movement of the floating socket 2 .

[0077] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it.
