Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a novel fast waterproof connector. Background Technology

[0002] In the existing technology, the power cord of the lamp is usually connected to the transformer. However, since the lifespan of the power module (such as the transformer) is much shorter than that of the light-emitting or electrical module, the integrated design requires the whole unit to be replaced when the power supply is damaged, which results in waste of resources and increased costs, and makes the maintenance and disassembly of the lamp cumbersome and complicated. Furthermore, it cannot meet users' needs for flexible adaptation and modular expansion. For example, multiple interfaces can be connected in parallel at the output end of the light string to facilitate multi-branch connection.

[0003] Therefore, in order to solve the above problems, it is necessary to develop a new type of quick-connect waterproof connector, which adopts a lockable and waterproof quick-release connection structure design. Both ends can be connected to lamps and transformers without tools, ensuring a reliable and secure connection. This facilitates future maintenance, disassembly, and replacement, and also meets the user's needs for flexible adaptation and modular expansion. Utility Model Content

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: like Figure 1-5 As shown, a novel fast waterproof connector includes a connector body, the connector body including a connecting wire 1; One end of the connecting line 1 is provided with a first connector assembly that connects to a transformer connector (not shown in the figure), and the other end is provided with a second connector assembly that connects to a lamp connector (not shown in the figure); The first connector assembly includes a first connector 2 and a first locking mechanism 3; The surface of the first connector 2 is provided with a raised Z-shaped metal guide plate 4, which is electrically connected to the connecting wire 1; The first locking mechanism 3 includes a detachably connected upper cover 31 and a bottom shell 32; An installation cavity 10 for installing the first connector 2 is formed between the upper cover 31 and the bottom shell 32; an insertion interface 20 is provided at the end of the upper cover 31 and the bottom shell 32 away from the first connector 2; The upper surface of the cover 31 is provided with a threaded hole 31a that communicates with the mounting cavity 10; The first locking mechanism 3 also includes a second locking element 32 that is threadedly connected to the threaded hole 31a; The second locking member 32 is used to prevent the transformer connector, which is electrically connected to the Z-shaped metal guide plate 4, from disengaging from the first connector 2 when locking; The second connector assembly includes a second connector 5 that is plugged into and disconnected from the luminaire connector, and a second locking assembly that restricts the luminaire connector from separating from the second connector 5.

[0017] In this embodiment, the first connector 2 is fixed in the mounting cavity 10 by connecting the upper cover 31 to the bottom shell 32. When connecting to the transformer, the transformer connector is inserted into the mounting cavity 10 through the plug interface 20 and electrically connected to the first connector 2 through the Z-shaped metal guide plate 4. Then, to prevent the transformer connector from separating from the first connector 2, the second locking member 32 is tightened by external force to press the transformer connector. When connected to a lamp, the lamp connector is plugged into the second connector 5 by plugging and unplugging. Then, external force is applied to the second locking component to lock it, preventing the lamp connector from separating from the second connector 5. The above structure adopts a lockable quick-release connection structure design. Compared with the existing integrated structure, both ends can be tool-free quick-releasely connected to the lamps and transformers respectively. This not only ensures a reliable and secure connection and facilitates later maintenance, disassembly, and replacement, but also meets the user's needs for flexible adaptation and modular expansion. In this embodiment, the detachable interface supports the series or parallel expansion of light strings in practical applications, and users can increase or decrease the number of lights according to their needs; at the same time, during maintenance, the lights, connectors and transformers can be separated, improving the convenience of maintenance and reducing unnecessary damage and loss during maintenance.

[0018] Furthermore, such as Figure 1 , 2 As shown in Figures 4 and 5, the second locking member 32 includes a wire clamping knob 321 and a wire clamping bolt 322; The pressure bolt 322 is disposed in the mounting cavity 10 and is located between the upper cover 31 and the first connector 2; The pressure bolt 322 is threadedly connected to the threaded hole 31a of the upper cover 31 via an external thread; The wire pressing knob 321 is located above the upper cover 31, and the wire pressing knob 321 is detachably connected to the wire pressing bolt 322; after the wire pressing knob 321 and the wire pressing bolt 322 are connected, they cannot rotate relative to each other; The wire clamping knob 321 is used to drive the wire clamping bolt 322 to rotate to move closer to or away from the first connector 2; The connected upper cover 31 and the bottom shell 32 cannot be separated from each other in the vertical direction.

[0019] In this embodiment, a transformer connector insertion space is formed between the wire clamping bolt 322 and the first connector 2; since the upper cover 31 and the bottom shell 32 are inseparable in the vertical direction after connection, it is ensured that the upper cover 31 will not be separated from the bottom shell 32 by the downward force of the locking member, thus ensuring the reliability of the clamping.

[0020] In this example, once the transformer connector is inserted into the mounting cavity 10 and in place, external force can rotate the wire clamping knob 321 to move the wire clamping bolt 322 closer to the first connector 2 until the transformer connector is pressed tightly onto the first connector 2, thereby achieving a highly reliable and stable connection between the connector and the transformer.

[0021] In this embodiment, since the wire pressing knob 321 and the wire pressing bolt 322 are detachably connected, the wire pressing bolt 322 of different first connector assemblies can be rotated by a single wire pressing knob 321, which effectively reduces costs and avoids the unsightly and abrupt appearance of placing the wire pressing knob 321 on the first connector assembly, thus improving the design aesthetics.

[0022] Furthermore, such as Figure 1 , 2 As shown in Figure 4, in order to drive the wire pressing bolt 322 to rotate relative to the upper cover 31 more reliably and with a more stable connection; the lower end of the wire pressing knob 321 is provided with a cross-shaped connecting end 321a; The upper surface of the pressure bolt 322 is provided with a cross groove 322a; the cross groove 322a is provided in correspondence with the cross connecting end 321a.

[0023] Furthermore, such as Figure 1 , 2 As shown in Figure 4, in order to improve the waterproof performance of the first connector assembly, a waterproof silicone sleeve 7 is provided in the mounting cavity 10 between the wire clamping bolt 322 and the first connector 2; The waterproof silicone sleeve 7 is connected to the bottom shell 32, and the waterproof silicone sleeve 7 has an insertion groove 7a extending from the insertion interface 20 to the inside. The Z-shaped metal guide plate 4 extends through the waterproof silicone sleeve 7 and then extends above the insertion groove 7a.

[0024] Furthermore, such as Figure 1 , 4 As shown in Figure 5, in order to enable tool-free disassembly and assembly of the upper cover 31 and the bottom shell 32, a sliding snap-fit ​​structure 8 is provided between the upper cover 31 and the bottom shell 32, which can slide and snap-fit ​​left and right.

[0025] Furthermore, such as Figure 1 As shown, in order to lock the second connector to the lamp connector, the second locking assembly includes a locking nut 6 that is threadedly connected to the lamp connector; the locking nut 6 is sleeved on the end of the second connector near the connecting wire 1; The second connector 5 is provided with a limiting protrusion 51 at the end away from the connecting line 1.

[0026] Furthermore, such as Figure 1 , 4 As shown, in order to improve the waterproof sealing of the connection between the second connector 5 and the lamp connector, a sealing ring 9 is provided on the side of the limiting protrusion 51 away from the locking nut 6.

[0027] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
