Description

Technical Field

[0001] This invention belongs to the field of electrical connector technology, and particularly relates to a current switching converter. Background Technology

[0002] Existing electrical connectors mainly achieve circuit connection through the mutual plugging of male plugs and female connectors, while most related male and female plugs on the market are directly plugged in.

[0003] For example, patent document with authorization announcement number "CN111613935B" discloses an electrical connector, a mating electrical connector, and an electrical connector assembly. The mating electrical connector includes a body portion and a first mating portion located at the front end of the body portion. The electrical connector also has a second mating portion and an outer sleeve that extends forward beyond the second mating portion and forms a receiving cavity at the front end of the second mating portion. The body portion includes a first body portion and a second body portion located at the front end of the first body portion and smaller in size than the first body portion. The first mating portion and the second mating portion are mated together, and the second body portion is received in the receiving cavity. The receiving cavity cooperates with the second body portion. This patented technical solution enhances the mechanical connection strength between the electrical connector and the mating electrical connector.

[0004] Current combiners and current shunts also fall under the category of electrical connectors. A current combiner is an electrical connector that combines multiple current branches into a single current, while a current shunt is an electrical connector that splits a single current into multiple branches.

[0005] For example, patent document CN212725868U discloses a high-current blind-mating connector with a contact-type end face. The high-current connector includes a structural housing, contact components, inter-component busbars, and external busbars. The contact components are elastically deformable, and multiple contact components are compactly arranged on the structural housing. Multiple inter-component busbars are arranged along the contact components and connected to contact components of the same power type and polarity, respectively summing the current. Multiple external busbars are staggered and connected to multiple inter-component busbars on the side of the structural housing. The contact components are connected to the external interface of the high-current connector through the inter-component busbars and the external busbars to achieve current transmission. This patented technology solves the problems of miniaturization, floating tolerance limitations, insertion / extraction force limitations, and heat dissipation in multi-variety high-current-throughput power blind-mating connectors within a compact space.

[0006] However, in current busbars and current shunts, the more branch currents there are, the more parallel wires are required. In existing current busbars and current shunts, the wires inside the connectors are generally arranged in the same plane, which forces the size of the electrical connectors to increase. This makes it difficult to use electrical connectors in confined spaces. In addition, when existing connectors are connected, the conductive parts are usually in rigid plane butt contact. When there are pits or bumps on the rigid plane, it will lead to poor electrical contact between the electrical connectors, affecting the reliability of the electrical connection. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a current switching converter.

[0008] This invention provides a current switching converter, including a shell, multiple limiting rings, and multiple wires. The shell has a cavity, and the limiting rings are housed in the cavity. The limiting rings have limiting holes and conductive springs. The limiting holes communicate with the guide holes, and the conductive springs surround the limiting holes. One end of each wire is electrically connected to the conductive springs, and the other end of each wire extends out of the shell.

[0009] One end of the shell is screwed to the guide sleeve, and the other end of the shell is fixed to the end cap with a pin. The guide sleeve has a guide hole, and the shell cavity communicates with the guide hole. The end cap covers the opening end of the shell cavity. The shell cavity also has multiple insulating spacers, and the insulating spacers are sandwiched between any two adjacent limiting rings, between the limiting rings and the inner wall surface of the shell cavity, and between the limiting rings and the end cap.

[0010] The current switching converter also includes a base and a floating cylinder. The surface of the base is provided with a receiving cavity. The floating cylinder is supported in the receiving cavity by an axial spring. The floating cylinder is provided with a positioning groove. The guide sleeve is supported in the positioning groove by a radial coil spring. The guide sleeve is also fixedly connected to a flange. The floating cylinder is also bonded and fixedly connected to a cover plate, so that the flange is clamped between the floating cylinder and the cover plate.

[0011] The guide sleeve is also fixedly connected to the core cylinder, and the core cylinder is also provided with an adjusting hole, which is connected to the guide hole.

[0012] The adjusting hole is conical in shape.

[0013] The surface of the floating cylinder is also provided with raised ribs, which abut against the bottom surface of the flange.

[0014] The floating cylinder is a stepped cylindrical body, and the length direction of the ribs coincides with the radial direction of the floating cylinder.

[0015] The bottom surface of the accommodating cavity is also fixedly connected to one end of the support column, and the other end of the support column is screwed to the pressure block. The support column also passes through the axial spring and the floating cylinder in sequence from bottom to top, and the floating cylinder is clamped between the axial spring and the pressure block.

[0016] The pressure block can be replaced by bolts.

[0017] The surface of the guide sleeve is also provided with an annular groove, and at least a portion of the radial coil spring is accommodated in the annular groove.

[0018] The beneficial effects of this invention are as follows: Using the technical solution provided by this invention, as the number of branch currents increases, the wires can be arranged along the outer circumference of the limiting ring. Finally, after bending the wires, they are arranged in an alternating pattern within the housing cavity, allowing multiple wires to extend out of the housing cavity in parallel. Compared to existing technologies, the wires are no longer limited to being arranged in the same plane, which helps to reduce the external size of the electrical connector, enabling it to be assembled and used in confined spaces. Furthermore, because the conductive spring is elastic, when the electrical connector provided by this invention is plugged into other electrical connectors, the contact between the rigid surface and the flexible surface of the conductive spring ensures good electrical contact between the connectors and guarantees reliable electrical connection.

Detailed Implementation

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited thereto; This invention provides a current switching converter, such as... Figures 1 to 13 As shown, the device includes a shell 14, multiple limiting rings 4, and multiple wires 5. The shell 14 has a cavity 15 inside, and the limiting rings 4 are accommodated in the cavity 15. The limiting rings 4 have limiting holes 16 and conductive springs 17 inside. The limiting holes 16 are connected to guide holes 13, and the conductive springs 17 surround the limiting holes 16. One end of the wires 5 is electrically connected to the conductive springs 17, and the other end of the wires 5 extends out of the shell 14.

[0022] By employing the technical solution provided by this invention, as the number of branch currents increases, the wires can be arranged along the outer circumference of the limiting ring. Finally, after bending the wires, they are arranged in an alternating pattern within the housing cavity, allowing multiple wires to extend parallel outside the cavity. Compared to existing technologies, the wires are no longer confined to the same plane, which helps reduce the overall size of the electrical connector, enabling assembly and application in confined spaces. Furthermore, due to the elasticity of the conductive spring, when the electrical connector provided by this invention is plugged into other electrical connectors, the contact between the rigid surface and the flexible surface of the conductive spring ensures good electrical contact between the connectors and guarantees reliable electrical connection.

[0023] Specifically, one end of the shell 14 is screwed to the guide sleeve 3, and the other end of the shell 14 is fixed to the end cap 28 with a pin 29. The guide sleeve 3 is provided with a guide hole 13, and the shell cavity 15 communicates with the guide hole 13. The end cap 28 covers the opening end of the shell cavity 15. The shell cavity 15 is also provided with multiple insulating spacers 30, and the insulating spacers 30 are sandwiched between any two adjacent limiting rings 4, between the limiting ring 4 and the inner wall surface of the shell cavity 15, and between the limiting ring 4 and the end cap 28.

[0024] In addition, the current switching converter also includes a base 1 and a floating cylinder 2. The surface of the base 1 is provided with a receiving cavity 6. The floating cylinder 2 is supported in the receiving cavity 6 by an axial spring 7. The floating cylinder 2 is provided with a positioning groove 11. The guide sleeve 3 is supported in the positioning groove 11 by a radial coil spring 12. The guide sleeve 3 is also fixedly connected to the flange 18. The floating cylinder 2 is also bonded and fixedly connected to the cover plate 21, so that the flange 18 is clamped between the floating cylinder 2 and the cover plate 21. Preferably, the guide sleeve 3, the flange 18, and the core cylinder 19 are integrally manufactured. The surface of the floating cylinder 2 is also provided with a raised rib 22, which abuts against the bottom surface of the flange 18. The floating cylinder 2 is a stepped cylindrical body, and the length direction of the raised rib 22 coincides with the radial direction of the floating cylinder 2. The guide sleeve 3 is also fixedly connected to the core cylinder 19. The core cylinder 19 is provided with an adjusting hole 20, which communicates with the guide hole 13. The adjusting hole 20 is conical in shape. By employing the technical solution of this invention, when the external electrical connector is plugged into the electrical connector provided by this invention, under the elastic force of the axial spring, the guide sleeve can float along the axial direction of the guide sleeve with the floating cylinder, and the floating cylinder can compensate for the axial deviation of the plug; under the elastic force of the radial coil spring, the guide sleeve can also float along its radial direction, and the guide sleeve can compensate for the radial deviation of the plug; thus, the plug and the guide sleeve are tightly fitted together, improving the reliability of the electrical connection. In addition, under the guidance of the core cylinder 19, the external electrical connector is aligned along the inner wall of the adjusting hole 20, so that the central axis of the external electrical connector coincides with the central axis of the guide sleeve, laying the foundation for improving the reliability of the electrical connection.

[0025] Furthermore, the bottom surface of the accommodating cavity 6 is fixedly connected to one end of the support column 23, and the other end of the support column 23 is screwed to the pressure block 24. The support column 23 also passes through the axial spring 7 and the floating cylinder 2 in a bottom-to-top sequence, and clamps the floating cylinder 2 between the axial spring 7 and the pressure block 24. Preferably, the pressure block 24 can be replaced by bolts. With the technical solution of the present invention, the support column 23 is used to guide the extension and retraction movement of the axial spring 7, avoiding the axial spring 7 from bearing an off-center load, so that the present invention can operate reliably.

[0026] In addition, the surface of the base 1 is provided with an ear seat 25, and the surface of the ear seat 25 is provided with a mounting hole 26. By adopting the technical solution of the present invention and providing the mounting hole 26, the base 1 and the interface bottom plate 31 can be fixed together, which is beneficial to expanding the application scope of the present invention.

[0027] Specifically, the radial coil spring 12 is made of beryllium copper. The surface of the guide sleeve 3 is also provided with an annular groove 27, and at least a portion of the radial coil spring 12 is accommodated within the annular groove 27.
