Description

Technical Field

[0001] This utility model belongs to the field of signal data transmission technology and relates to a waterproof connector. Background Technology

[0002] Waterproof connectors are critical electronic connection components used in humid, outdoor, or harsh environments. The main function of waterproof connectors is to prevent moisture and corrosive substances from penetrating the connection parts of the connector and interface through a sealing structure, that is, to ensure that the male and female ends are in a sealed and waterproof environment.

[0003] Existing waterproof connectors generally have a dedicated interface structure designed inside the housing. For example, a Chinese invention patent with application number 2015101366043, entitled "Waterproof Network Connector and RJ45 Connector," has the defect of fixed and single interface type. A single product only supports a specific interface (such as only adapting to RJ45) and cannot be used to support interfaces such as fiber optic connectors, RCA, F-type connectors, BNC, USB, and HDMI. Therefore, the versatility and compatibility of existing waterproof connectors are insufficient. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a waterproof connector.

[0005] The objective of this utility model can be achieved through the following technical solution: a waterproof connector, comprising:

[0006] The main module is provided with a universal card slot, which is configured to accommodate different interface modules.

[0007] A waterproof housing, at least one of which is connected to the end of the main module. The main module and the waterproof housing together form a waterproof chamber, and the universal slot is located inside the waterproof chamber.

[0008] Preferably, the universal slot is configured as a rectangular through hole structure extending along the axial direction of the main body module, the openings at both ends of the universal slot are located at the end faces of both ends of the main body module, and the two side walls of the universal slot are provided with buckle portions.

[0009] Preferably, the interface module includes a base and an interface portion, the interface portion being located within the base, the base being snapped into the universal slot, and elastic buckles and limiting buckles being respectively provided on both sides of the base, the elastic buckles engaging with one of the buckle portions, and the limiting buckles engaging with the other buckle portion, thereby making the base detachably connected to the main module.

[0010] Preferably, the two ports of the universal card slot have the same diameter, and the universal card slot allows the interface module to have two symmetrical insertion angles in the circumferential direction.

[0011] Preferably, a shielding part is provided on one end face of the main module, the shielding part is located at the edge of one port of the universal card slot, and the shielding part covers the gap between the one port of the universal card slot and the outline of the interface module.

[0012] Preferably, there are two waterproof outer shells, and the two waterproof outer shells are respectively connected to both ends of the main module.

[0013] Preferably, one end of the main body module is provided with a first threaded connection part, and the other end of the main body module is provided with a second threaded connection part, and the two waterproof shells are respectively threadedly connected to the first threaded connection part and the second threaded connection part.

[0014] Preferably, the port of the main module has a quick-release notch.

[0015] Preferably, a sealing ring is installed between the waterproof outer shell and the end face of the main module.

[0016] Preferably, the waterproof housing is equipped with a waterproof ring and a waterproof cap. The end of the waterproof housing away from the main module is provided with a plurality of fastening claws along its circumference. The waterproof ring is located within the space formed by the fastening claws. The waterproof cap is connected to the end of the waterproof housing with the fastening claws by a thread.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The main module in this design can adapt to different types and specifications of interfaces. In actual use, the required interface modules can be installed into the universal slot of the main module, and the interface modules are placed in a waterproof chamber to prevent water vapor and corrosive substances from entering the internal circuit, thus extending the service life of the interface and greatly improving the versatility and compatibility of this waterproof connector.

[0019] 2. The base and the main module are connected in a detachable manner, which means that the interface module can be easily installed into or removed from the universal slot through simple operations. This design improves the flexibility and adaptability of the connector.

[0020] 3. Because the two ends of the universal slot have the same diameter and allow the interface module to have two symmetrical insertion angles (0° and 180°) in the circumferential direction, installers do not need to pay special attention to orientation when installing the interface module. Regardless of the angle at which the interface module is inserted, as long as it is aligned with the universal slot, installation can be completed smoothly. Attached Figure Description

Detailed Implementation

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] like Figures 1 to 10As shown, a waterproof connector includes: a main module 100, the main module 100 being provided with a universal slot 110, the universal slot 110 being configured to accommodate different interface modules 300; a waterproof housing 200, the number of waterproof housings 200 being at least one, the waterproof housing 200 being connected to the end of the main module 100, the main module 100 and the two waterproof housings 200 forming a waterproof chamber, the universal slot 110 being located within the waterproof chamber.

[0034] The main module 100 is the core component of the waterproof connector, featuring a universal slot 110. The universal slot 110 is designed to be highly flexible, accommodating and accommodating different types of interface modules 300. This means that users can replace different interface modules 300 as needed (e.g., RJ45, fiber optic, BNC, F-type connectors, USB, HDMI, etc.) without having to replace the entire connector.

[0035] The waterproof connector is designed to ensure the stability and safety of electronic device connections in humid or underwater environments. Therefore, the waterproof connector is equipped with a waterproof housing 200, which connects to the end of the main module 100 to form a sealed waterproof chamber. This design effectively prevents moisture and other impurities from entering the interior, thus ensuring the safety and normal operation of the connector's internal components.

[0036] The universal card slot 110 equipped with the main module 100 is not used to fix or install a single type of interface, but can accommodate a variety of different types and specifications of interface modules 300. This means that whether it is an RJ45 interface, fiber optic interface, BNC interface, F-type connector, or other types of interface, as long as they are designed to conform to the standard of the universal card slot 110, they can be installed in this card slot.

[0037] Thanks to the universal card slot 110, users can flexibly select and replace different interface modules 300 according to their actual needs. By simply replacing the interface module 300 without replacing the entire connector or device, this design allows a single connector to meet diverse interface connection requirements, greatly enhancing its practical value.

[0038] From the perspective of manufacturers or suppliers, adopting this universal slot 110 design also simplifies product line and inventory management. There's no need to produce or stock large quantities of dedicated connectors for different interfaces; simply producing a few different types of interface modules 300 is sufficient to meet market demand. This not only reduces costs but also increases the speed of response to market changes.

[0039] It should be noted that this waterproof connector itself does not include the interface module 300. In actual use, the required interface module 300 can be selected and then assembled with the main module 100. The interface module 300 can be any of various types, including but not limited to wired network interfaces, fiber optic coupler interfaces, audio / video transmission interfaces, control signal interfaces, power interfaces, mixed signal interfaces, and special industry interfaces. Specifically, the compatible interface module 300 type can cover one of the following options:

[0040] Wired network interface: such as RJ45 (Cat5e / 6 / 6a / 7 / 8 standard);

[0041] Fiber optic interfaces: such as LC, SC, or ST types;

[0042] Coaxial cable connectors: including BNC and F type connectors;

[0043] Audio and video transmission interfaces: such as HDMI, DisplayPort, and 3.5mm audio interface;

[0044] Control signal interfaces: such as RS232, RS485 and CAN bus;

[0045] General purpose and special purpose interfaces: USB interface, aviation plug;

[0046] Power interface: Industrial power terminals (such as M12, M8 specifications);

[0047] Power over Ethernet (PoE) interface.

[0048] like Figures 1 to 6 As shown, based on the above embodiment, the universal slot 110 is configured as a rectangular through hole structure extending along the axial direction of the main module 100. The openings at both ends of the universal slot 110 are located on the end faces at both ends of the main module 100, and both sides of the universal slot 110 are provided with a latching part 120.

[0049] The universal slot 110 extends along the axial direction of the main module 100 (i.e., the length direction of the connector). This design helps simplify the insertion and removal process of the interface module 300. Furthermore, the use of a rectangular through-hole as the universal slot 110 provides stable support and positioning for different types of interface modules 300, thus restricting rotation of the interface module 300. Two latching parts 120 are symmetrically arranged at the opening of the universal slot 110 to enable a detachable connection between the interface module 300 and the universal slot 110.

[0050] Based on the above embodiments, the interface module 300 includes a base 310 and an interface part 330. The interface part 330 is located inside the base 310, and the base 310 is snapped into the universal slot 110 and detachably connected to the main module 100.

[0051] The base 310 is the fundamental component of the interface module 300. It is designed to snap into the universal slot 110 of the main module 100. The main function of the base 310 is to provide physical support for the interface section 330 and, through its shape design, ensure that the interface module 300 can be securely mounted on the main module 100. The interface section 330 is located inside the base 310 and specifically implements functions such as data transmission, signal transmission, or power supply. Depending on the application scenario requirements, the interface section 330 can be one of the following types: RJ45, optical fiber interface, HDMI, USB, etc.

[0052] The base 310 and the main module 100 are connected in a detachable manner, which means that the interface module 300 can be easily installed into or removed from the universal slot 110 with simple operations. This design improves the flexibility and adaptability of the connector.

[0053] Based on the above embodiments, elastic buckles 320 and limiting buckles 340 are respectively provided on both sides of the base 310. The elastic buckles 320 and the limiting buckles 340 are symmetrically arranged. The elastic buckle 320 is fastened to one buckle part 120, and the limiting buckle 340 is fastened to the other buckle part 120, so that the base 310 and the main module 100 can be detachably connected.

[0054] The elastic buckle 320 is typically made of a material with a certain degree of flexibility (such as certain types of plastics or metals), capable of deforming under external force and returning to its original shape after the external force is removed. The elastic buckle 320 and the limiting buckle 340 can respectively fasten the two buckle parts 120, thereby achieving axial locking between the base 310 and the universal slot 110 through the buckle structure, thus realizing the detachable connection between the base 310 and the main module 100.

[0055] When the base 310 with the elastic latch 320 is inserted into the universal slot 110, the elastic latch 320 deforms, allowing the base 310 to slide smoothly into the universal slot 110 until the elastic latch 320 and the limiting latch 340 are engaged with the two latching parts 120 respectively. At this time, the elastic latch 320 will automatically reset and latch into the latching part 120 due to its elasticity, thus completing the secure connection between the base 310 and the main module 100. This latching mechanism not only provides the necessary physical constraint to ensure that the interface module 300 will not easily loosen or detach, but also allows the user to release the latch by applying appropriate pressure or using specific tools, so as to quickly replace the interface module 300.

[0056] In addition, both the main module 100 and the interface module 300 are provided with limiting surfaces. When the interface module 300 is connected to the main module 100, the two limiting surfaces fit together to limit the axial movement.

[0057] Based on the above embodiment, the latching part 120 is provided with a chamfered surface 121. When the base 310 passes over the latching part 120, the chamfered surface 121 forces the elastic latch 320 to deform and radially shrink.

[0058] The chamfered surface 121 is located at the snap-fit ​​portion 120, and is typically beveled or rounded at the entrance edge of the snap-fit ​​portion 120. The main purpose of this design is to guide the elastic snap 320 on the base 310 to smoothly transition as it passes over the snap-fit ​​portion 120, and to automatically deform and radially contract during this process.

[0059] When the user inserts the base 310 with the elastic latch 320 into the universal slot 110 and continues to push it until it encounters the latch part 120, the chamfered surface 121 begins to function. Due to the presence of the chamfered surface 121, as the base 310 is further inserted, the chamfered surface 121 gradually applies pressure to the elastic latch 320, forcing it to deform and contract inward (radially), making the installation of the interface module 300 smoother.

[0060] Example 1:

[0061] like Figures 1 to 4 As shown, the universal card slot 110 has the same diameter at both ports, and the universal card slot 110 allows the interface module 300 to have two symmetrical insertion angles in the circumferential direction.

[0062] Because the two ports of the universal card slot 110 have the same diameter and allow the interface module 300 to have two symmetrical insertion angles (0° and 180°) in the circumferential direction, installers do not need to pay special attention to orientation when installing the interface module 300. Regardless of the angle from which the interface module 300 is inserted, as long as it is aligned with the universal card slot 110, installation can be completed smoothly.

[0063] In practical applications, especially in scenarios requiring rapid deployment or replacement of the interface module 300, the design's ability to insert at any angle significantly reduces the time needed for adjustment and alignment. Construction personnel do not need to spend extra time confirming the correct insertion direction of the interface module 300, thus improving overall work efficiency.

[0064] Example 2:

[0065] like Figure 1 , Figure 5 , Figure 6As shown, a shielding part 111 is provided on one end face of the main module 100. The shielding part 111 is located at the edge of one port of the universal card slot 110, and the shielding part 111 covers the gap between one port of the universal card slot 110 and the outline of the interface module 300.

[0066] In the second embodiment, the shielding part 111 is located at the edge of the opening at one end of the front of the interface module 300 corresponding to the universal card slot. The shielding part 111 is designed to fit closely with the outline of the front end of the interface module 300. That is, the front outline of the interface module 300 is adapted to the size of the opening at one end of the universal card slot 110. This can effectively shield any possible gaps or irregularities and ensure a neat appearance.

[0067] Unlike Embodiment 1, in Embodiment 2, the diameters of one port and the other port on the front of the interface module 300 corresponding to the universal card slot 110 are different. This design means that the interface module 300 has only one insertion angle and cannot be installed at other angles.

[0068] Example 3:

[0069] like Figure 7 As shown, there is only one waterproof outer shell 200. The waterproof outer shell 200 is connected to one port of the main body module 100, thereby sealing one port of the main body module 100, while the other end of the main body module 100 is connected to a box or other object, thereby sealing the other port of the main body module 100.

[0070] Example 4:

[0071] like Figures 1 to 6 , Figures 8 to 10 As shown, there are two waterproof housings 200, and the two waterproof housings 200 are respectively connected to the two ends of the main module 100.

[0072] Based on Embodiment 4, one end of the main module 100 is provided with a first threaded connection part 130, and the other end of the main module 100 is provided with a second threaded connection part 140. The two waterproof shells 200 are respectively threadedly connected to the first threaded connection part 130 and the second threaded connection part 140.

[0073] Two waterproof housings 200 correspond to the threaded connections at both ends of the main module 100. During installation, each waterproof housing 200 must be tightened onto its corresponding threaded connection. This threaded connection method not only connects the waterproof housing 200 to the main module 100 but also ensures a good seal, forming a robust and highly waterproof overall structure.

[0074] Based on the above implementation method, a sealing ring 400 is installed between the end faces of the waterproof outer shell 200 and the main module 100.

[0075] The sealing ring 400 provides an effective seal between the two contact surfaces. When the waterproof housing 200 is tightly connected to the main module 100, the sealing ring 400 is compressed, filling any possible tiny gaps or unevenness, thus forming a tight waterproof barrier. The sealing ring 400 effectively prevents external contaminants such as moisture and dust from entering the connector, even under harsh environmental conditions.

[0076] Based on the above implementation method, the port of the main module 100 is provided with a quick-release notch 141.

[0077] In Embodiment 3, the quick-release notch 141 is located at one port of the main body module 100 corresponding to the elastic buckle 320, that is, at the rear port of the main body module 100.

[0078] In Embodiment 4, the main body module 100 has two quick-release notches 141 at its port, and the two quick-release notches 141 are symmetrically arranged about the axis of the main body module 100. Specifically, the quick-release notches 141 are directly formed on the second threaded connection portion 140, and the position of the quick-release notches 141 corresponds to the elastic buckle 320, allowing the user to directly contact the elastic buckle 320 through these notches. When it is necessary to disconnect the connection between the base 310 and the main body module 100, the user can press the elastic buckle 320 through these quick-release notches 141.

[0079] During the actual disassembly process, the user uses two fingers to pinch the base 310 of the interface module 300 through the two quick-release notches 141, and then presses the elastic buckle 320 to make it retract radially, thereby disengaging from the locked state of the buckle part 120, unlocking the interface module 300 and removing it from the universal slot 110.

[0080] like Figures 1 to 9 As shown, based on the above embodiment, the waterproof housing 200 is equipped with a waterproof ring 220 and a waterproof cap 230. The end of the waterproof housing 200 away from the main module 100 is provided with a plurality of fastening claws 210 along its circumference. The waterproof ring 220 is located in the space formed by the fastening claws 210. The waterproof cap 230 is connected to the end of the waterproof housing 200 with the fastening claws 210 by a thread.

[0081] The cable of the interface and connector enters from the end of the waterproof housing 200 and passes through a small hole located in the waterproof ring 220. The waterproof ring 220 is designed to tightly wrap around the cable, preventing moisture from seeping into the connector along the cable. The waterproof cap 230 is threaded to one end of the waterproof housing 200 where the fastening claw 210 is located. When the waterproof cap 230 is tightened, it gradually pushes inward and applies radial pressure to the fastening claw 210. Due to the elasticity of the fastening claw 210, it can bend or contract inward under radial pressure, thereby clamping the waterproof ring 220 located therein. This forces the waterproof ring 220 to fit tightly against the cable surface, effectively eliminating any possible gaps between the waterproof ring 220 and the cable. This tight contact not only prevents moisture intrusion but also provides additional physical protection against external impurities.

[0082] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0083] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0084] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0085] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
