Description

Technical Field

[0001] This utility model relates to a cable accessory, and more particularly to a cable connector. Background Technology

[0002] Cable connectors are primarily used for signal transmission between various digital program-controlled exchanges, optoelectronic transmission equipment, and patch panels, for transmitting data, audio, video, and other communication devices. There are also specialized mid-range connectors for cable connections. Because some cables consist of multi-strand wires with larger connection diameters, traditional connectors with their simple structures are insufficient for most applications. For example, simple threaded sleeves can be used for installation and fixing at the junction box. Utility Model Content

[0003] In view of the shortcomings of existing technology, this utility model provides a cable connector.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cable connector, including a connecting seat, an inner sleeve, a closing sleeve, and a screw ring. The connecting seat is a cylindrical structure with a through-center. The connecting seat has external threads at both ends and a limiting flange between the two ends. The inner sleeve has a stepped structure in the radial projection. The outer wall of the inner sleeve has an upper step and a lower step. The outer diameter of the lower step is adapted to the inner diameter of the connecting pipe, and the outer diameter of the upper step is adapted to the inner diameter of the closing sleeve. The two ends of the inner sleeve are respectively fitted into the connecting seat and the closing sleeve. The connecting seat and the closing sleeve are fixedly connected by threads. The end of the connecting seat facing away from the closing sleeve is threadedly connected to the screw ring.

[0005] Preferably, a stop ring is provided on the inner wall of the connecting seat, and the stop ring and the flange are positioned opposite each other in the radial direction of the connecting pipe.

[0006] Preferably, the closing sleeve has a clamp with a gradually narrowing diameter.

[0007] Preferably, the inner wall of the closing sleeve at the clamp has an annular arc surface.

[0008] Preferably, the flange and the outer surface of the closing sleeve have a regular hexagonal structure.

[0009] Preferably, the inner sleeve is an insulating rubber sleeve.

[0010] The beneficial effects of this utility model are as follows: The cable connector provided by this utility model adopts a threaded combination structure, which can provide limited protection and strengthen the cable connection. The design is simple, reliable, delicate and reasonable, and has practicality and economy. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] like Figure 1 As shown, a cable connector includes a connecting seat 1, an inner sleeve 2, a closing sleeve 3, and a screw ring 4. The connecting seat 1 is a cylindrical structure with a through-center. The connecting seat 1 has external threads at both ends and a limiting flange 5 between the two ends. The inner sleeve 2 has a stepped structure in its radial projection. The outer wall of the inner sleeve 2 has an upper step 6 and a lower step 7. The outer diameter of the lower step 7 matches the inner diameter of the connecting pipe, and the outer diameter of the upper step 6 matches the inner diameter of the closing sleeve 3. The two ends of the inner sleeve 2 are respectively fitted into the connecting seat 1 and the closing sleeve 3. The connecting seat 1 and the closing sleeve 3 are fixed by a threaded connection. The end of the connecting seat 1 facing away from the closing sleeve 3 is threadedly connected to the screw ring 4. Using the inner sleeve 2 as protection at the cable connection point, combined with the tightening effect of the connecting seat 1 and the closing sleeve 3, helps to strengthen the connection and narrow the protection. Based on the threaded connection, the stepped design of the inner sleeve 2 helps to enhance positioning stability, making it less prone to misalignment during installation. The flange 5 design serves two purposes: indicating the installation position and limiting the connection.

[0013] The inner wall of the connector 1 is provided with a stop ring, which is radially opposite to the flange 5 in the connecting pipe. The stop ring is designed to further increase the reliability of cable insertion and prevent the inner sleeve 2 from deforming or deviating. The retaining sleeve 3 has a clamp 9 with a gradually narrowing diameter. The inner wall of the retaining sleeve 3 at the clamp 9 has an annular arc surface. The clamp 9 is designed to narrow after multiple strands of wire are inserted, maintaining structural stability and preventing easy pulling or detachment. The annular arc surface has a certain guiding effect on the cable harness, and the interaction force during pulling is actually more conducive to increasing resistance. The outer surfaces of the flange 5 and the retaining sleeve 3 are hexagonal, and tools can be used when disassembly is required to avoid excessive tightness that would prevent operation. The inner sleeve 2 is an insulating rubber sleeve, which is beneficial to line stability and meets design requirements.

[0014] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. At the same time, the basic principles, main features, and advantages of this utility model have been shown and described above, which should be understood by those skilled in the art.
