Wire waterproof connector, lamp and assembling method

Abstract

This invention discloses a waterproof wire connector, a lamp, and an assembly method. The connector includes a first connector, a second connector, a transfer connector, and an internal adapter assembly. The first end of the first connector is threaded to the opening of the lampshade, and the second connector is threaded to the first connector and sleeved on the outside of its second end. The transfer connector is located in the middle of the first connector and has an axially penetrating wiring channel. The internal adapter assembly is located between the first connector and the second connector. This invention achieves waterproofing of both the lampshade and the connection between the first and second connectors. The internal adapter assembly located between the first and second connectors forms a closed enclosure, with the connection point between the external and internal wires housed within the internal adapter assembly. This prevents the connection point from being exposed to the interior space of the lampshade, making it less susceptible to moisture and oxidation, and also preventing dust and moisture from corroding the connection point.

Description

[0002] In the field of lighting fixtures, especially when it comes to the mechanical connection and electrical conduction between the lampshade and the light-emitting element, it is usually necessary to introduce an external power cord into the lampshade and establish a reliable electrical connection with the light-emitting element. At the same time, to ensure the safety and lifespan of the luminaire in humid, outdoor, or rainy environments, the connection points must have excellent waterproof sealing performance.

[0003] In existing technologies, the industry typically creates lead-in holes and installs waterproof connectors on the lampshade, or uses a separate waterproof junction box to connect the external and internal wires before introducing them into the lampshade. However, in practical applications, the connection points between the external and internal wires are usually only wrapped with electrical tape or simple terminal blocks, leaving them directly exposed inside the lampshade. This makes them susceptible to moisture and oxidation, posing safety hazards.

[0059] Example 1 Reference Figures 1 to 7 This embodiment provides a waterproof wire connector 100 for connecting a lampshade 80 and a light-emitting element 90 (such as...). Figure 17 and Figure 18(As shown). The waterproof wire connector 100 includes a first connector 10, a second connector 20, a transfer connector 30, and an internal adapter assembly 40. It should be noted that, in this embodiment, the lampshade 80 using the above-mentioned waterproof wire connector 100 is typically a lampshade 80 with only one opening 81.

[0060] Reference Figures 1 to 4 The first connector 10 is generally cylindrical, having a first end 11 and a second end 12. The first connector 10 includes a main board 101 and an annular wall 102 extending from the edge of the main board 101 toward the light-emitting body 90. The main board 101 is circular, and the annular wall 102 has an annular sidewall structure. The end of the annular wall 102 closer to the light-emitting body is the first end 11, and the surface of the main board 101 away from the light-emitting body is the second end 12. Both the first end 11 and the second end 12 are circular wall surfaces. Exemplarily, in this embodiment, the material of the first connector 10 is preferably plastic, such as polyamide (PA), polypropylene (PP), or acrylonitrile-butadiene-styrene copolymer (ABS), which is integrally molded by injection molding. Preferably, the first end 11 of the first connector 10 is provided with a second external thread 14 for rotatably engaging with a second internal thread 82 provided at the opening 81 of the lampshade 80, thereby achieving a waterproof and secure connection between the first connector 10 and the lampshade 80. The second end 12 of the first connector 10 is provided with a first external thread 13 for waterproof connection with the second connector 20. At the axial center between the first end 11 and the second end 12 of the first connector 10, there is a through hole 16 that penetrates the main board 101 along the axial direction, and at least a portion of the inner wall of the through hole 16 is provided with a third internal thread 15.

[0061] Reference Figures 1 to 4 The second connector 20 is a cover structure. In this embodiment, the second connector 20 includes a top plate 201 and a side wall 202 surrounding the top plate 201 near the light-emitting end. The top plate 201 is circular, and the top plate 201 and the side wall 202 are integrally formed. The inner wall of the side wall 202 is provided with a first internal thread 21. The first internal thread 21 is adapted to the first external thread 13 on the outside of the second end 12 of the first connector 10 and can be rotatably engaged to achieve a waterproof connection. By screwing the first internal thread 21 and the first external thread 13 together, the second connector 20 is sleeved and threadedly connected to the outside of the second end 12 of the first connector 10. After the second connector 20 is connected to the first connector 10, an internal receiving space 101 can be formed between the second end 12 of the first connector 10 and the interior of the second connector 20. The connection point of the external wire and the internal wire, as well as the internal adapter component 40, can be placed inside the second connector 20 after assembly, and then the first connector 10 is screwed in.

[0062] Reference Figures 1 to 4The transfer connector 30 is a hollow cylinder, meaning it is a hollow cylindrical body. The hollow portion inside the transfer connector 30 forms an axially penetrating wiring channel 31 for wires to pass through. At least a portion of the outer wall surface 301 of the transfer connector 30 is provided with a third external thread 32 along the axial direction of the transfer connector 30. This third external thread 32 is adapted to the third internal thread 15 within the through hole 16 of the first connector 10. The transfer connector 30 is axially adjustable in the through hole 16 of the first connector 10 via the threaded engagement. The operator can adjust the length of the transfer connector 30 extending into the lampshade 80 by rotating it to extend or retract axially relative to the first connector 10 from the end closest to the light source / bottom end of the first connector 10. An internal adapter assembly 40 is disposed in the internal receiving space between the first connector 10 and the second connector 20. The internal adapter assembly 40 is used to realize the electrical transfer between the external wire 50 and the internal wire.

[0063] Reference Figure 6 The second connector 20 is provided with a waterproof wiring structure 22. The waterproof wiring structure 22 includes a wire hole 23 on the top plate 201 of the second connector 20, a terminal 24 at the port of the wire hole 23, and a waterproof nut 25 at the terminal 24. For example, the wire hole 23 is opened at the axis of the top plate 201; the terminal 24 extends outward along the axis from the port of the wire hole 23. The terminal 24 includes an external thread on its bottom outer circumference and a plurality of axially slotted tapered elastic claws on its top. The waterproof nut 25 has an internal thread adapted to the external thread, and the inner end of the waterproof nut 25 is provided with a tapered surface. When the external conductor 50 passes through the waterproof nut 25 and the wire hole 23 in sequence, and the waterproof nut 25 is tightened, its tapered surface presses the elastic claws of the terminal 24 to narrow radially inward, thereby tightly gripping the outer insulation of the external conductor 50. This structure achieves both waterproof sealing and the ability to withstand the tension of the power cord. An elastic sealing ring 26 (such as a silicone O-ring) can also be added between the waterproof nut 25 and the terminal 24 to further improve the sealing performance.

[0064] The first end of the internal adapter 40, which connects to the external wire 50, is electrically connected to the external wire 50 inside the second connector 20. The second end of the internal adapter 40, which connects to the light-emitting element 90, can be selectively placed within the wiring channel 31 of the intermediate connector 30, for example, by embedding a plug at the port of the intermediate connector 30 to connect with the light-emitting element 90 (e.g.). Figure 3 , Figure 4 and Figure 7 (as shown), or extend through the wiring channel 31 to the outside of the first connector 10 (as shown). Figure 1 , Figure 2 , Figure 5and Figure 6 (As shown), used for electrical connection with the light source 90 located further away.

[0065] Reference Figure 6 In this embodiment, triple waterproof protection is achieved through the threaded connection between the first connector 10 and the lampshade 80, the threaded connection between the first connector 10 and the second connector 20, and the clamping and sealing of the wire 50 by the waterproof nut 25. At the same time, the axially adjustable design of the transfer connector 30 allows the wiring length to be flexibly adjusted according to actual needs, adapting to the assembly requirements of lampshades 80 of different depths or different light-emitting bodies 90.

[0066] Example 2 Based on Embodiment 1, this embodiment further defines the internal adapter component 40.

[0067] It should be noted that the waterproof connector in this embodiment is not limited to the specific structure described below. Any existing general-purpose connector that can accommodate wire connection points and has a certain waterproof capability (such as commercially available IP68 junction boxes, potted terminal blocks, etc.) can be directly replaced.

[0068] Reference Figure 6 and Figure 8 The internal adapter assembly 40 includes a waterproof connector 41, an internal positive wire 42, and an internal negative wire 43. The waterproof connector 41 accommodates the connection point a (i.e., the position where the copper cores are twisted together after the wires are stripped) between the external wire 50 and the internal positive wire 42 and internal negative wire 43. The waterproof connector 41 can have the following specific structure: The waterproof connector 41 includes a container 411 and a cover 412. The container 411 is conical or box-shaped, with an internal cavity for accommodating the wire connection point, and its interior is covered with waterproof adhesive. The cover 412 is threaded to the container 411 (e.g., the container 411 has an external thread at its opening, and the cover 412 has an internal thread). The cover 412 has one or more slots or silicone slits 413 in its center for the internal positive wire 42 or internal negative wire 43 to pass through. A spring 414 (e.g., a coil spring or wave spring) is disposed between the cover 412 and the interior of the container 411. One end of the spring 414 abuts against the bottom of the container 411 or the wire connection point, and the other end abuts against the inside of the cover 412. When the cover 412 is tightened, the spring 414 inside the container 411 is compressed, generating a preload force on the cover 412, making it difficult to loosen.

[0069] During assembly, first screw the container 411 and the cover together, then twist the positive and negative core wires of the external wire 50 to one end of the internal positive wire 42 and the internal negative wire 43 respectively, and then insert them into the container 411 corresponding to the silicone seam 413. The waterproof connector 41 is housed in the receiving space between the first connector 10 and the second connector 20.

[0070] After the other end (i.e. the second end) of the internal positive wire 42 and the internal negative wire 43 passes through the waterproof connector 41, it can extend into the wiring channel 31 of the transfer connector 30, or further extend to the outside of the first connector 10 through the wiring channel 31 as needed, to adapt to different types of light emitters 90.

[0071] Example 3 Based on Embodiment 1, this embodiment further defines the storage space 103 and the accommodating structure between the first connector 10 and the second connector 20.

[0072] Reference Figure 6 The end face of the first connector 10 facing the second connector 20 is provided with a receiving step 17 (i.e., a stepped structure formed by the inward indentation of the central area of ​​the end face). The end face of the top plate 201 of the second connector 20 is an outwardly protruding conical end face 27, thereby naturally forming a conical space inside the second connector 20. When the first connector 10 and the second connector 20 are connected, the receiving step 17 and the conical end face 27 together form a storage space 103, which is used to store excess wire length in the internal adapter assembly 40, preventing the wires from piling up or being squeezed between the first connector 10 and the second connector 20, ensuring internal cleanliness and preventing wire breakage. Moreover, the thread stroke of the first connector 10 and the second connector 20 can be screwed in deeper.

[0073] Specifically, at least one receiving groove 18 is provided on the end face of the first connector 10 facing the second connector 20. Preferably, there are two receiving grooves 18, symmetrically arranged on both sides of the through hole 16 in the middle of the first connector 10, and positioned close to the through hole 16. This means that the other end (i.e., the second end) of the internal positive wire 42 and internal negative wire 43 of the waterproof connector 41 leading out from the receiving groove 18 is shorter after passing through the waterproof connector 41 to the transfer connector 30, effectively avoiding messy wiring. The shape of each receiving groove 18 is adapted to the shape of the waterproof connector 41. When the first connector 10 and the second connector 20 are fully screwed together, the waterproof connector 41 (especially its container 411 part) is completely or partially contained within the receiving groove 18. The receiving groove 18 not only serves a positioning function, preventing the waterproof connector 41 from shaking within the housing, but also further saves internal space, making the overall structure more compact. When the internal adapter assembly 40 contains two independent waterproof connectors 41 (e.g., one for the positive terminal and one for the negative terminal), the two receiving recesses 18 can respectively accommodate the two waterproof connectors 41, achieving physical isolation between the positive and negative terminals and effectively preventing short circuits.

[0074] Example 4 This embodiment provides a specific implementation of a lamp holder connection structure 60, which is used to detachably connect the waterproof wire connector 100 of any of the aforementioned embodiments to a standard E27 lamp holder (or other light-emitting body 90 with external threads).

[0075] Reference Figures 9 to 12 The lamp holder connection structure 60 includes a snap-fit ​​connector 61 and a base 63.

[0076] The snap-fit ​​connector 61 is generally annular or cylindrical, with a through mounting hole 611 at its center. The intermediate connector 30 extends beyond the first connector 10, and this portion also has an external thread structure, passing through the mounting hole 611. Then, a nut 62 is screwed into the external thread at the front end of the intermediate connector 30 from its end (it should be noted that this external thread can be an extension of the aforementioned third external thread 32, or a separately provided thread segment). By tightening the nut 62, the snap-fit ​​connector 61 is clamped and fixed between the end face of the first connector 10 and the nut 62. The outer periphery of the snap-fit ​​connector 61 is provided with snap-fit ​​connecting portions 612, such as two or three evenly distributed protruding claws, with hooks at the ends of the claws. In this embodiment, preferably, two symmetrically arranged snap-fit ​​connecting portions 612 are symmetrically arranged on the outer periphery of the snap-fit ​​connector 61 at the end away from the intermediate connector 30.

[0077] The main structure of the base 63 is preferably cylindrical. Preferably, an electrical insertion groove 631 is provided at the center of the end face of the base 63 away from the intermediate connector 30. The inner wall of the electrical insertion groove 631 is provided with internal threads for connection to a light-emitting element 90 with external threads (e.g., an E27 LED bulb). Figure 16 The light-emitting element 90 shown is threadedly connected. One or more contact portions 632 are provided at the bottom of the electrical connector groove 631 for contacting and communicating with the end contacts of the light-emitting element 90 (e.g., the bottom contacts of an E27 bulb). The internal thread portion of the electrical connector groove 631 itself acts as a conductor, communicating with the external threads of the light-emitting element 90 (e.g., the metal casing threads of an E27 bulb). The outer periphery of the base 63 is provided with mating snap-fit ​​portions 633 (e.g., recessed grooves adapted to the snap-fit ​​connection portions 612 of the snap-fit ​​connector 61). The base 63 achieves a quick and detachable snap-fit ​​connection with the snap-fit ​​connector 61 through the engagement of the snap-fit ​​connection portions 612 and the mating snap-fit ​​portions 633.

[0078] Regarding electrical connections, the internal positive wire 42 and internal negative wire 43, extending from the waterproof connector 41, pass through the wiring channel 31 of the transfer connector 30 and are respectively connected to the contact portion 632 of the base 63 and the threaded portion of the electrical connector slot 631 by plugging, soldering, or wire connection. Specifically, the internal positive wire 42 is connected to the contact portion 632, and the internal negative wire 43 is connected to the threaded portion of the electrical connector slot 631. Those skilled in the art will understand that the connection of the positive and negative electrodes can be adjusted accordingly based on the polarity definition of the light-emitting element 90.

[0079] When it is time to install a light bulb, simply screw the E27 bulb into the electrical socket 631 of the base 63. The bulb end contacts abut against the contact part 632, and the external thread of the bulb is connected to the internal thread of the electrical socket 631, thus establishing a circuit connection. The snap-fit ​​connection between the base 63 and the snap-fit ​​connector 61 allows users to quickly disassemble and assemble the entire lamp holder, facilitating maintenance.

[0080] Example 5 Reference Figure 13 , Figure 14 and Figure 17 This embodiment provides another specific implementation of the lamp holder connection structure 60, used to connect the waterproof wire connector 100 of the aforementioned embodiment one to a DC bulb (such as...). Figure 17 The light-emitting body 90 shown has a male plug 65 and circumferentially distributed LED light chip patches (connected by LED strips) and supports 360° unobstructed rotation.

[0081] The lamp holder connection structure 60 includes a plug / female connector 64. This plug / female connector 64 is fixedly disposed at the cylindrical port 33 of the transfer connector 30. As a preferred process, the plug / female connector 64 is integrally molded into the cylindrical port 33 of the transfer connector 30; that is, during the injection molding of the transfer connector 30, the plug / female connector 64 is placed into the mold as an insert, so that the plastic material covers the tail of the plug / female connector 64, forming a robust, integrated structure. The plug / female connector 64 is preferably a DC power plug / female connector or an audio plug / female connector.

[0082] The corresponding light-emitting element 90 is provided with a male plug 65 that is compatible with the female plug 64. When the male plug 65 is inserted into the female plug 64, electrical conduction is formed between the two. Since the male plug 65 and the female plug 64 are in cylindrical contact, the male plug 65 (together with the light-emitting element 90) can rotate freely 360° relative to the female plug 64 (and the entire connector 100) without interrupting the electrical connection or generating any torsional stress on the internal wires.

[0083] In this embodiment, after the internal positive wire 42 and the internal negative wire 43 pass through the wiring channel 31 of the transfer connector 30, they are directly soldered to the positive and negative contacts (e.g., the center pole and the outer ring pole) of the plug female 64. After injection molding, the internal positive wire 42 and the internal negative wire 43 are connected to the external wires respectively.

[0084] Example 6 This embodiment provides two preferred arrangements for the first external thread 13 and the second external thread 14 on the outside of the first connector 10.

[0085] Reference Figure 16 Option 1: Continuous Thread Design. The first external thread 13 and the second external thread 14 of the first connector 10 are interconnected, that is, the first external thread 13 and the second external thread 14 are integrated, so that the outer circumference of the first connector 10 forms a continuous external thread portion extending from the first end 11 to the second end 12. This design has a simple structure, is easy to process, and is suitable for conventional environments where the waterproofing requirements are not particularly stringent.

[0086] Reference Figure 17Option 2: Stepped Sealing Solution. A radially outward-protruding step 19 is provided between the first external thread 13 and the second external thread 14 of the first connector 10, such that the diameter of the cylinder containing the second external thread 14 is smaller than the diameter of the cylinder containing the first external thread 13. A sealing element 70, such as a silicone O-ring or a flat washer, is provided at the step 19. An abutment surface 83 adapted to the step 19 is provided at the lampshade opening 81. When the first connector 10 and the lampshade 80 are tightened together via the second external thread 14, the abutment surface 83 of the step 19 and the lampshade 80 approach each other and compress the sealing element 70, forming an additional end-face seal. This solution further improves the waterproof performance at the connection between the first connector 10 and the lampshade 80, making it suitable for outdoor or humid environments.

[0087] Example 7 Refer to 15 to Figure 17 This embodiment provides a lamp 200, including the waterproof wire connector 100, light-emitting element 90, and lampshade 80 described in any of the preceding embodiments. The light-emitting element 90 is connected to and electrically conductive with the waterproof wire connector 100 (the specific connection method can be found in the snap-fit ​​E27 solution of Embodiment 4 or the plug-type DC solution of Embodiment 5). The lampshade 80 has an opening 81 with a second internal thread 82, which is rotatably connected to the second external thread 14 of the first end 11 of the first connector 10 in the waterproof wire connector 100. When the connector 100 is screwed entirely into the lampshade opening 81, the light-emitting element 90 is completely located inside the lampshade 80, and most or all of the structure of the connector 100 is also accommodated within the lampshade opening 81, resulting in a neat and aesthetically pleasing overall appearance of the lamp 200.

[0088] Reference Figures 18 to 21 In the specific assembly process of the snap-on E27 bulb solution in Embodiment 4, the user can complete the assembly of the lamp 200 by following these steps: S1: Strip the positive and negative terminals of one end of the external power cord 50, and insert the entire cord into the waterproof nut 25.

[0092] S5 inserts the part of the connection point a into the waterproof connector 41 and places the waterproof connector 41 into the receiving groove 18 on the end face of the first connector 10.

[0093] S6 screws the first connector 10, which is equipped with the internal adapter assembly 40, and the second connector 20 together by threading.

[0094] S7 Tighten the waterproof nut 25 to clamp and secure the external wire 50.

[0095] S8 connects to the transfer connector 30 via nut 62, clamping and fixing the snap-fit ​​connector 61 to the first connector 10.

[0096] The portions of the positive conductor 42 and the negative conductor 43 inside S9 that pass through the intermediate connector 30 are respectively connected to the electrical connection points of 63 to form an electrical connection.

[0097] S10 installs the base 63 onto the snap-fit ​​connector 61 using a snap-fit ​​mechanism.

[0098] S11 then connects the light-emitting element 90 (E27 bulb) to the lamp holder connection structure 60.

[0099] S12 connects the lampshade 80 to the second external thread 14 of the first end 11 of the first connector 10 via a threaded connection, thereby achieving overall installation.

[0100] S13 connects the other end of the external conductor 50 to the mains power supply to achieve overall power-on.

[0101] Reference Figures 22 to 24 In the specific assembly process of the plug-type DC bulb solution of Embodiment 5, the user can complete the assembly of the lamp 200 by following these steps: L1: Strip the positive and negative terminals of one end of the external power cord 50, and insert the entire cord into the waterproof nut 25.

[0102] L2 inserts one end of the external power cord 50, with its positive and negative terminals, into the second connector 20 through the wire hole 23.

[0103] L3 passes the internal positive wire 42 and the internal negative wire 43 through the transfer connector 30, and then threads the transfer connector 30 to the through hole 16 of the first connector 10.

[0104] L4 connects the positive terminal of the external conductor 50 to the internal positive conductor 42 between the first connector 10 and the second connector 20, and the negative terminal is connected to the internal negative conductor 43 in the same way.

[0105] L5 inserts the part of the connection point a into the waterproof connector 41 and places the waterproof connector 41 into the receiving groove 18 on the end face of the first connector 10.

[0106] L6 connects the first connector 10, which contains the internal adapter assembly 40, and the second connector 20 by screwing them together.

[0107] Tighten L7 to secure the waterproof nut 25 to clamp and fix the external wire 50.

[0108] L8 electrically connects the male plug 65 and the female plug 64 of the light-emitting element 90 (DC bulb).

[0109] L9 connects the lampshade 80 to the second external thread 14 of the first end 11 of the first connector 10 via a threaded connection, thereby achieving overall installation.

[0110] L10 connects the other end of the external conductor 50 to the mains power supply to achieve overall power-on.

[0111] Those skilled in the art will understand that, in the foregoing embodiments, the first connector 10, the second connector 20, and the intermediate connector 30 are preferably made of plastic materials, such as polyamide PA6, PA66, polycarbonate PC, acrylonitrile-butadiene-styrene copolymer ABS, or polybutylene terephthalate PBT. These materials have good insulation, mechanical strength, and weather resistance, and are easy to injection mold. For applications requiring higher mechanical strength, the first connector 10 may also be made of metal materials (such as brass or stainless steel), but an insulating sleeve must be added at the threaded connection to prevent short circuits. The waterproof nut 25, the seal 70, etc., are preferably made of aging-resistant rubber or silicone.

[0112] Those skilled in the art should understand that, based on the technical solutions disclosed in this invention, various substitutions or modifications can be made without departing from the essence of this invention. For example, the waterproof connector 41 can directly use a commercially available general-purpose waterproof junction box, whose internal structure (such as terminal block, potting seal, etc.) is prior art and will not be described in detail here. Furthermore, the connection method between the first connector 10 and the second connector 20 is not limited to a single-threaded connection; multi-threaded or sawtoothed threads can also be used, as long as a screw-on seal can be achieved. Additionally, the snap-fit ​​connection in the lamp holder connection structure 60 can be replaced by a push-pull quick-connect structure, which also allows for quick assembly and disassembly. All these alternative solutions fall within the protection scope of this invention.

[0113] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can make various improvements and modifications without departing from the spirit and principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
