Description

Technical Field

[0001] This invention relates to the field of connectors, and more specifically to a power supply connector. Background Technology

[0002] Power supply connectors involve the physical connection between electronic devices to enable signal transmission and power supply. Connectors are typically made of conductive materials, such as metal or plastic, which have conductivity and mechanical strength. When designing and manufacturing connectors, the following background technologies need to be considered: contact technology, conductive materials, shielding technology, environmental adaptability, standards and certifications.

[0003] However, current connectors involve a cumbersome wiring process, requiring repeated disassembly and reassembly of components with tools. This results in low efficiency in wire connection and fixation, significantly increasing the workload for construction workers and limiting their usability. Furthermore, the fully enclosed, opaque housing structure makes it impossible to visually inspect the internal wiring status and the working condition of conductive components. Faults such as loose wires and poor contact are difficult to detect in a timely manner. Moreover, the housing assembly is merely a simple splicing, resulting in poor positioning accuracy and sealing. External dust and moisture can easily penetrate the internal cavity, corroding conductive and wiring components and shortening the overall lifespan of the device. Summary of the Invention

[0004] This invention addresses the technical problems existing in the prior art by providing a power supply connector.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a power supply connector, comprising a protective housing assembly, a wiring and connection assembly, and a support and fixing assembly; The protective housing assembly forms a closed internal mounting cavity. The wiring and connection assembly is fixedly installed at the center of the internal cavity of the protective housing assembly. The support and fixing assembly is fixedly connected to the bottom of the protective housing assembly to achieve overall stable support. The protective housing assembly has a transparent and visible structure to monitor the internal working status in real time. The wiring and connection assembly has a quick docking structure to simplify wire connection operations. The protective housing assembly includes a base plate, an outer shell, and a top cover. The bottom of the outer shell is snapped and fixed to the top of the base plate. The top cover seals and closes to the top opening of the outer shell. A glass window is embedded and fixed in the middle of the top cover. The wiring and connection assembly includes terminals, wires, connecting tubes, and wiring nuts. The terminals are fixedly installed in the center of the internal cavity of the housing. The connecting tubes are symmetrically fixed to the outer walls of the left and right sides of the housing. The outer end of the connecting tube is coaxially and fixedly connected to the wiring nut. The inner end of the connecting tube has a wiring hole communicating with the internal cavity of the housing. The wire passes through the wiring nut, connecting tube, and wiring hole in sequence and is then fixedly connected to the terminal. The protective housing assembly forms a closed cavity, protecting the internal components. The supporting and fixing assembly is located at the bottom to ensure overall stability. The protective housing assembly is connected to the housing by a base plate and sealed with a top cover to form a complete housing. The glass window on the top cover allows for internal visibility. The wiring and connection assembly forms a wire passage channel through the connecting tubes, wiring nuts, and wiring holes on both sides of the housing. After the wire is inserted, it is fixedly connected to the terminal.

[0006] In a preferred embodiment, a plurality of threaded holes are equidistantly provided around the top perimeter of the outer casing, and screws are inserted around the perimeter of the top cover at positions corresponding to the threaded holes. The screws are threadedly locked into the threaded holes to achieve a detachable and sealed fixation between the top cover and the outer casing.

[0007] In a preferred embodiment, in order to prevent dust and moisture from entering the interior of the housing and to improve the overall structural strength of the housing, this application is approved. The top edge of the bottom plate is integrally formed with an annular locking block, which engages with the inner wall of the bottom of the housing in a circumferential manner to form a positioning seal between the bottom plate and the housing.

[0008] In a preferred embodiment, the system further includes a support and fixing component, which comprises a support structure fixedly installed at the bottom of the base plate; The support structure is any one of the following: base, fixing adhesive and / or anti-slip legs; Furthermore, the base is a plate-shaped support component, and the base is integrally fixed to the bottom of the base plate to support the connector as a whole; The adhesive is an bonding layer and is directly fixed to the bottom of the base plate to achieve wall / counter surface bonding and fixing of the connector; The anti-slip legs are anti-slip support feet, fixed to the bottom of the base plate to increase the friction of the contact surface and achieve anti-slip support. It should be noted that the base is a plate-shaped component, integrally fixed to the bottom of the base plate, providing large-area stable support; the adhesive layer allows the connector to be pasted onto walls, countertops, and other flat surfaces; the anti-slip legs are support feet that achieve anti-slip support by increasing friction. These three structures adapt to different installation scenarios and meet diverse fixing needs.

[0009] In a preferred embodiment, a plurality of heat dissipation holes are evenly opened on the top of the terminal block, and a grid is fixedly connected to the periphery of the heat dissipation holes. The grid covers the heat dissipation holes and forms a protective heat dissipation structure. The copper sheet inside the grid serves as a conductive carrier. The retainer presses the end of the wire tightly against the upper surface of the copper sheet, so that the wire and the copper sheet are in close contact to form a stable conductive connection and prevent the wire from loosening. In some other specific embodiments, the copper sheet can be equivalently replaced by an aluminum conductive sheet, a silver alloy conductive sheet, or a copper-aluminum composite conductive sheet, and the retainer can be equivalently replaced by an elastic pressure plate, a bolt pressure block, or a snap-on pressure piece, all of which can achieve a tight conductive connection between the wire and the conductive piece.

[0010] In a preferred embodiment, a copper sheet is fixedly installed at the center of the inside of the grid, and a retainer is fixedly installed on the top of the copper sheet. The retainer presses and fixes the end of the wire to the upper surface of the copper sheet, thereby achieving a stable conductive connection between the wire and the copper sheet.

[0011] In a preferred embodiment, an insulating sleeve is fitted onto the outer surface of the conductor, the insulating sleeve wraps around the outer periphery of the conductor to form an insulating protective layer, and a conductive wire is threaded through the center of the conductor.

[0012] In a preferred embodiment, after the end insulating sleeve of the conductive wire is removed, it passes through the wiring hole and extends into the interior of the outer casing. The end of the conductive wire is tightly attached to the upper surface of the copper sheet to form a closed conductive path.

[0013] Specifically, after the insulation sleeve at the end of the conductive wire is removed, it passes through the wiring hole and extends into the inside of the housing, where it fits tightly with the copper sheet to form a closed conductive path, ensuring that power is stably transmitted from the wire to the wiring terminal. The design of removing the insulation ensures the effectiveness of the conductive contact.

[0014] In a preferred embodiment, the glass window is vertically positioned facing the wiring terminals inside the housing, forming an unobstructed internal observation channel for real-time monitoring of the working status of the wiring terminals and wires. In a preferred embodiment, the terminal block is connected to the wire via a retainer to form a detachable clamping connection, and the terminal nut is coaxially engaged with the connecting tube to jointly form a quick insertion, positioning and locking structure for the wire.

[0015] The beneficial effects of this invention are as follows: the quick-connection structure of the wiring and conduction components simplifies the wire threading, positioning, and locking process, allowing wiring operations to be completed without complex tools, effectively reducing the workload of construction personnel. Furthermore, the connection status and working condition of the internal wiring terminals and wires can be observed in real time, enabling the troubleshooting of potential faults. The combination of wiring terminals and wires increases the practicality of the device during use, making wire wiring operations more convenient. The wiring terminals allow for the connection and fixation of wires during use, securing the wires within the equipment to prevent loosening or detachment, thereby ensuring the stability and reliability of the circuit.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] As attached Figure 1-6 As shown, this embodiment provides: a power supply connector, including a protective housing assembly, a wiring continuity assembly, and a support and fixing assembly; The protective housing assembly forms a closed internal mounting cavity. The wiring and connection assembly is fixedly installed at the center of the internal cavity of the protective housing assembly. The support and fixing assembly is fixedly connected to the bottom of the protective housing assembly to achieve overall stability. The protective housing assembly has a transparent and visible structure to monitor the internal working status in real time. The wiring and connection assembly has a quick-connect structure to simplify wire connection operations. The protective housing assembly includes a base plate 2, an outer shell 1, and a top cover 3. The bottom of the outer shell 1 is snapped and fixed to the top of the base plate 2. The top cover 3 seals and covers the top opening of the outer shell 1. A glass window 12 is embedded and fixed in the middle of the top cover 3. The wiring and conduction assembly includes a terminal block 4, a wire 5, a connecting tube 7, and a wiring nut 8. The terminal block 4 is fixedly installed in the center of the internal cavity of the housing 1. The connecting tube 7 is symmetrically fixed on the outer walls of the left and right sides of the housing 1. The outer end of the connecting tube 7 is coaxially fixedly connected to the wiring nut 8. The inner end of the connecting tube 7 has a wiring hole 9 that communicates with the internal cavity of the housing 1. The wire 5 passes through the wiring nut 8, the connecting tube 7, and the wiring hole 9 in sequence and is then fixedly connected to the terminal block 4.

[0020] The protective housing assembly forms a closed cavity to protect the internal parts, and the supporting and fixing assembly is located at the bottom to ensure overall stability. The protective housing assembly is connected to the outer shell 1 by the base plate 2 and sealed by the top cover 3 to form a complete shell. The glass window 12 of the top cover 3 allows for internal visibility. The wiring and conduction assembly forms a wire passage channel through the connecting pipes 7 on both sides of the outer shell 1, the wiring nuts 8 and the wiring holes 9. After the wire 5 is inserted, it is fixed and connected to the wiring terminal 4. In some other specific embodiments, the outer shell 1 can be equivalently replaced by an integrated injection-molded shell or a spliced ​​metal shell, and in the wiring and conduction assembly, the connecting pipe 7 can be equivalently replaced by a flexible insulated conduit or a metal corrugated pipe, and the terminal block 4 can be equivalently replaced by a modular terminal block or a pluggable conductive terminal, which can also realize the rapid insertion and conduction of the wire 5.

[0021] The top of the outer casing 1 has several threaded holes 6 at equal intervals around its perimeter. Screws 13 are inserted around the top cover 3 at positions corresponding to the threaded holes 6. The screws 13 are threadedly locked to the threaded holes 6, thereby achieving a detachable and sealed fixation between the top cover 3 and the outer casing 1.

[0022] As described above, threaded holes 6 are equidistantly arranged around the top of the outer casing 1. The top cover 3 is screwed into the threaded holes 6 by screws 13, achieving a detachable and sealed fixation. This ensures the airtightness of the casing and facilitates subsequent disassembly and maintenance of the internal wiring terminals 4 and wires 5. Alternatively, this application also provides other connection methods, such as snap-fit ​​connection, quick-release bolt connection, and rotary locking connection. Screws 13 can be equivalently replaced by hexagon socket head cap screws, cross-head screws, and expansion clips. The equidistant arrangement of the threaded holes 6 can be equivalently replaced by a symmetrical arrangement or a four-corner single-point arrangement, all of which can achieve a detachable and sealed fixation between the top cover 3 and the outer casing 1.

[0023] In order to prevent dust and moisture from entering the shell and to improve the overall structural strength of the shell, this application is approved. The top edge of the base plate 2 is integrally formed with an annular locking block 10. The annular locking block 10 is engaged with the inner wall of the bottom of the shell 1 in a circumferential manner, and forms a positioning seal between the base plate 2 and the shell 1.

[0024] It also includes a support and fixing component, which includes a support structure 11 fixedly installed at the bottom of the base plate 2; The support structure 11 is any one of the base 1101, the fixing adhesive 1102 and / or the anti-slip leg 1103; Furthermore, the base 1101 is a plate-shaped support component, and the base 1101 is integrally fixed to the bottom of the base plate 2 to support the connector as a whole; The fixing adhesive 1102 is an adhesive layer and is directly fixed to the bottom of the base plate 2 to achieve wall / counter surface adhesion and fixing of the connector; The anti-slip leg 1103 is an anti-slip support foot. The anti-slip leg 1103 is fixed to the bottom of the base plate 2 to increase the friction of the contact surface and achieve anti-slip support.

[0025] It should be noted that the base 1101 is a plate-shaped component, integrally fixed to the bottom of the base plate 2, providing large-area stable support; the fixing adhesive 1102 is an adhesive layer that allows the connector to be pasted onto flat surfaces such as walls and countertops; the anti-slip legs 1103 are support feet that increase friction to achieve anti-slip support. These three structures are suitable for different installation scenarios and meet diverse fixing needs. In addition to the three fixing and support methods proposed in this application, there are other equivalent alternatives, which will not be elaborated here.

[0026] A plurality of heat dissipation holes 14 are evenly opened on the top of the terminal block 4. A grid 15 is fixedly connected to the periphery of the heat dissipation holes 14. The grid 15 covers the heat dissipation holes 14 and forms a protective heat dissipation structure. The copper sheet 16 inside the grid 15 serves as a conductive carrier. The fixing device 17 presses the end of the wire 5 tightly onto the upper surface of the copper sheet 16, so that the wire 5 and the copper sheet 16 are in close contact to form a stable conductive connection and prevent the wire 5 from loosening. In some other specific embodiments, the copper sheet 16 can be equivalently replaced by an aluminum conductive sheet, a silver alloy conductive sheet, or a copper-aluminum composite conductive sheet. The fixing device 17 can be equivalently replaced by an elastic pressure plate, a bolt pressure block, or a snap-on pressure piece, all of which can achieve a tight conductive connection between the wire 5 and the conductive piece.

[0027] A copper sheet 16 is fixedly installed in the center of the inside of the grille 15. A fixture 17 is fixedly installed on the top of the copper sheet 16. The fixture 17 presses and fixes the end of the wire 5 to the upper surface of the copper sheet 16, so as to achieve a stable conductive connection between the wire 5 and the copper sheet 16.

[0028] An insulating sleeve 18 is fitted onto the outer surface of the conductor 5. The insulating sleeve 18 wraps around the outer periphery of the conductor 5 to form an insulating protective layer. A conductive wire 19 is threaded through the center of the conductor 5.

[0029] After the end insulating sleeve 18 is removed from the conductive wire 19, it passes through the wiring hole 9 and extends into the inside of the outer casing 1. The end of the conductive wire 19 is tightly attached to the upper surface of the copper sheet 16 to form a closed conductive path.

[0030] Specifically, after the end insulation sleeve 18 is removed from the conductive wire 19, it passes through the wiring hole 9 and extends into the interior of the housing 1, where it fits tightly with the copper sheet 16 to form a closed conductive path, ensuring that power is stably transmitted from the wire 5 to the wiring terminal 4. The design of removing the insulation ensures the effectiveness of the conductive contact.

[0031] The glass window 12 is vertically positioned facing the wiring terminal 4 inside the outer casing 1, forming an unobstructed internal observation channel for real-time viewing of the working status of the wiring terminal 4 and the wire 5.

[0032] The terminal 4 is connected to the wire 5 by the retainer 17 to form a detachable clamping connection. The terminal nut 8 and the connecting tube 7 are coaxially engaged to form a quick insertion, positioning and locking structure for the wire 5.
