Description

Technical Field

[0001] This utility model relates to the field of Remo connector technology, and in particular to a connector with protective function. Background Technology

[0002] In modern industrial equipment and communication systems, the protective performance of connectors directly affects signal transmission stability and equipment lifespan. Remo connectors are a widely used type of connector. While traditional threaded connectors possess a basic sealing structure, they have certain shortcomings in dusty environments or when liquids penetrate. Currently, Remo connectors are generally threaded installation structures, which can easily form tiny gaps at the connection point. Moisture and particles from the environment can slowly penetrate along these gaps, and condensation or seeping liquids can easily accumulate in the threaded engagement area, leading to corrosion of metal components or a decrease in insulation performance. Furthermore, external mechanical impacts often cause deformation of the connector housing, thereby compromising the alignment accuracy of the internal terminals. Conventional metal shielding covers are mostly of fixed sizes, making it difficult to adapt to application scenarios with varying installation depths.

[0003] Therefore, this application provides a connector with protective function to solve the above-mentioned technical problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a connector with protective function to solve the problem that there are tiny gaps at the middle connection of the connector in the prior art, which make it easy for water vapor and particles to get in.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A connector with protective function includes a metal connector head and a tail cap. A threaded cylinder is fixed to the end of the metal connector head. A sealing ring is fixed around the connection between the threaded cylinder and the metal connector head. The end of the tail cap is provided with a threaded cavity for threaded insertion and installation with the threaded cylinder. A drain hole is provided at the port of the threaded cavity.

[0006] Optionally, a protective sleeve is threaded onto the outer center of the metal connector, and an extension sleeve is inserted into the end of the protective sleeve. The protective sleeve and the extension sleeve together cover the connection between the metal connector and the tail cap.

[0007] Optionally, a wire clamp is provided both inside the metal connector and the tail cap, and a rubber core is fixed inside the wire clamp, with a connecting terminal provided in the middle of the rubber core.

[0008] Optionally, the metal connector has an external thread in the middle, and the protective sleeve has an internal thread at the end away from the extension sleeve.

[0009] Optionally, an installation cavity is provided in the inner wall of the protective cylinder, and one end of the extension cylinder is inserted into the installation cavity.

[0010] Optionally, the drain hole has an outwardly expanding conical structure, with the inner port diameter being smaller than the outer port diameter.

[0011] Optionally, the cross-section of the sealing ring has an asymmetrical double-peak structure, including a rigid main peak that contacts the threaded cylinder and an elastic secondary peak that tilts towards the tail cap.

[0012] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, thanks to the setting of the sealing ring and the drain hole, the sealing ring can be used to prevent dust and moisture from entering between the metal connector and the end cap through the gap, and the drain hole can be used to discharge the moisture accumulated in the gap, which has a good dustproof and waterproof effect.

[0013] In the above solution, thanks to the setting of the protective tube and the extension tube, the connection of the metal connector and the tail cap can be covered and protected by the extension tube. This not only further improves the dustproof and waterproof protection effect, but also further improves the metal shielding effect and ensures signal quality.

[0014] In summary, this device has good waterproof and dustproof effects, and further ensures signal quality, resulting in good overall performance. Attached Figure Description

[0024] like Figure 1-4 As shown, an embodiment of this utility model provides a connector with protective function, including a metal connector head 1 and a tail cap 2. A threaded cylinder 101 is fixed to the end of the metal connector head 1, and the threaded cylinder 101 and the metal connector head 1 are manufactured by a precision one-piece molding process. A sealing ring 102 is fixed around the connection between the threaded cylinder 101 and the metal connector head 1. The sealing ring 102 is made of wear-resistant, corrosion-resistant, and highly elastic silicone rubber material, which allows the sealing ring 102 to fit tightly against the connection, effectively preventing dust and moisture from entering between the metal connector head 1 and the tail cap 2 through the gap, providing a reliable first line of defense for the connector. In other embodiments, the cross-section of the sealing ring 102 has an asymmetrical double-peak structure, including a rigid main peak in contact with the threaded cylinder 101 and an elastic secondary peak inclined towards the tail cap 2.

[0025] The end of the tail cap 2 is provided with a threaded cavity 201 for threaded insertion and installation with the threaded cylinder 101. During installation, align the threaded cavity 201 of the tail cap 2 with the threaded cylinder 101 of the metal connector 1, and slowly rotate the tail cap 2 to ensure a tight connection. A drain hole 202 is provided at the port of the threaded cavity 201. The drain hole 202 ensures that water vapor and other impurities blocked by the sealing ring 102 can be discharged smoothly, preventing them from accumulating inside and reducing their impact on the connector performance. In specific implementation, the drain hole 202 has an outwardly expanding tapered structure, with the inner port diameter being smaller than the outer port diameter.

[0026] The outer center of the metal connector 1 has an external thread, and the end of the protective sleeve 6 away from the extension sleeve 601 has a matching internal thread. The protective sleeve 6 is threadedly installed on the outer center of the metal connector 1. During installation, the internal thread of the protective sleeve 6 is aligned with the external thread of the metal connector 1, and the protective sleeve 6 is rotated to secure it firmly to the metal connector 1. The extension sleeve 601 is inserted into the end of the protective sleeve 6. A mounting cavity 602 is formed in the inner wall of the protective sleeve 6, and one end of the extension sleeve 601 is inserted into the mounting cavity 602. The extension sleeve 601 can extend and retract within the mounting cavity 602 to meet the protection requirements of different usage scenarios. When the connector is in use, the extension sleeve 601 extends out from the mounting cavity 602 of the protective sleeve 6, so that the protective sleeve 6 and the extension sleeve 601 together cover the connection between the metal connector 1 and the tail cap 2. This not only further improves the dustproof and waterproof protection, preventing dust and moisture from entering the connector from the connection point, but also effectively reduces the impact of external electromagnetic interference on the internal signal of the connector due to the shielding effect of the protective sleeve 6 and the extension sleeve 601, ensuring signal quality.

[0027] A wire clamp 3 is installed inside both the metal connector 1 and the end cap 2. The wire clamp 3 securely holds the cable, ensuring a stable and reliable connection between the cable and the connector. A rubber core 4 is fixed inside the wire clamp 3. The rubber core 4 is made of polytetrafluoroethylene (PTFE) plastic with excellent insulation properties, and a connecting terminal 5 is located in its center. The connecting terminal 5 is made of a gold alloy material with good conductivity. When the cable is inserted into the connector 1, the conductor portion of the cable contacts the connecting terminal 5. Through the fixing action of the wire clamp 3, a tight and stable connection is formed between the cable and the connecting terminal 5.

[0028] The working principle provided by this utility model is that, when using this connector with protective function, the cable is first inserted into the metal connector head 1 and the tail cap 2 so that the conductor part of the cable contacts the connecting terminal 5, and the cable is fixed with the wire clamp 3 to ensure a firm connection.

[0029] Then, the tail cap 2 is threadedly inserted into the threaded sleeve 101 of the metal connector 1 through the threaded cavity 201. During installation, the sealing ring 102 acts as a seal, effectively preventing dust and moisture from entering the connector. Next, depending on the actual usage environment, the protective sleeve 6 is threadedly installed on the outer middle of the metal connector 1, and the extension sleeve 601 extends out from the mounting cavity 602 of the protective sleeve 6, covering the connection between the metal connector 1 and the tail cap 2, providing all-round protection.

[0030] Meanwhile, when moisture accumulates inside the connector, it can be discharged through the drain hole 202 at the threaded cavity 201 port of the tail cap 2.

[0031] In summary, through the ingenious design of the sealing ring 102, drain hole 202, protective cylinder 6, and extension cylinder 601, this device has excellent waterproof and dustproof effects, further ensuring signal quality. It has good overall performance and can meet the high requirements of connector protection performance in different fields.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
