Description

Technical Field

[0001] This utility model relates to the field of cables, and in particular to a cable joint device. Background Technology

[0002] Cables, as signal connection lines between various electrical appliances, instruments and automatic devices, are mainly used for signal transmission and control signal transmission in control, monitoring interlocking circuits and protection circuits, and are widely used in various industrial and mining enterprises, transportation and other important economic fields.

[0003] In existing technologies, the connection between cables is relatively complicated, requiring multiple screws to fix the two cable ends together. The screws are difficult to remove, and if the cable becomes loose during the laying process, personnel need to disassemble the cable joint for repair. The process is cumbersome, time-consuming, and not conducive to saving economic costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cable connector device.

[0005] The cable connector device provided by this utility model adopts the following technical solution:

[0006] A cable connector device includes a connector head, a first sleeve, and a second sleeve. A limiting component is disposed within the first sleeve, which also has a cavity. The limiting component is disposed within the cavity and includes an elastic element and a limiting rod. One end of the limiting rod is hinged within the cavity and abuts against the elastic element. The connector head includes an end, a connecting shaft, a sleeve, and a connecting ring. The two ends of the connecting shaft are respectively connected to the end and the sleeve. The diameter of the connecting shaft is smaller than the diameters of the end and the sleeve. The connecting ring is sleeved on the connecting shaft, and its diameter is equal to the diameters of the end and the sleeve. The connecting ring is in sliding engagement with the connecting shaft.

[0007] Optionally, the first sleeve is threadedly connected to the second sleeve.

[0008] Optionally, an annular groove is provided inside the second sleeve, and a sealing ring is provided inside the annular groove.

[0009] Optionally, a gasket may also be provided inside the annular groove.

[0010] Optionally, a limit ring is provided on the sleeve, and a detachable limit block is provided on the limit ring.

[0011] Optionally, when the connector is stationary relative to the first sleeve, the limiting ring abuts against the end of the first sleeve.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. When it is necessary to connect the connector and the sleeve, insert the connector into the sleeve. The end of the connector first abuts against the limiting rod and pushes the limiting rod, so that the limiting rod exerts pressure on the elastic element and moves outward. After the end passes, the limiting rod is reset and locked into the connecting shaft under the action of the elastic element, thus fixing the connector.

[0014] 2. When it is necessary to disassemble the connector, simply remove the limiting ring first, move the connector towards the second sleeve, the connecting ring squeezes the limiting rod, causing the limiting rod to apply pressure to the elastic element again, so that the limiting rod abuts against the outer wall of the connecting ring. At this time, pull the connector outward. Due to the friction between the limiting rod and the connecting ring, the connecting ring moves from near the sleeve to near the end, so that the end can be smoothly pulled out from the first sleeve. This solution does not require screw riveting, which greatly improves the connection and fixing efficiency of the connector, and disassembly and assembly are very convenient.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] Furthermore, "several" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] This utility model discloses a cable connector device. (Refer to...) Figure 1 A cable connector device includes a connector 1, a first sleeve 2, and a second sleeve 3. A limiting component is disposed within the first sleeve 2, and a cavity 4 is provided within the first sleeve 2. The limiting component is disposed within the cavity 4 and includes an elastic element 5 and a limiting rod 6. One end of the limiting rod 6 is hinged within the cavity 4 and abuts against the elastic element 5. The connector 1 is provided with an end 7, a connecting shaft 8, a sleeve 9, and a connecting ring 10. The two ends of the connecting shaft 8 are respectively connected to the end 7 and the sleeve 9. The diameter of the connecting shaft 8 is smaller than the diameter of the end 7 and the sleeve 9. The connecting ring 10 is sleeved on the connecting shaft 8. The diameter of the connecting ring 10 is equal to the diameter of the end 7 and the sleeve 9. The connecting ring 10 and the connecting shaft 8 are in sliding fit. With this design, when it is necessary to connect the connecting head 1 and the sleeve 2, the connecting head 1 is inserted into the sleeve 2. The end 7 of the connecting head 1 first abuts against the limiting rod 6 and pushes the limiting rod 6, so that the limiting rod 6 exerts pressure on the elastic element 5 and moves outward. After the end 7 passes, the limiting rod 6 is reset and locked onto the connecting shaft 8 under the action of the elastic element 5. (Reference) Figure 2 This forms a fixation of connector 1.

[0025] A limiting ring 14 is provided on the sleeve 9, and a detachable limiting block is provided on the limiting ring 14. When the connector 1 and the first sleeve 2 are relatively stationary, the limiting ring 14 abuts against the end of the first sleeve 2, thereby preventing the end 7 from further entering the second sleeve 3, forming a limiting and fixing effect on the connector 1. When it is necessary to remove the connector 1, simply remove the limiting ring 14 first, and move the connector 1 towards the second sleeve 3. (Refer to...) Figure 3 The connecting ring 10 presses against the limiting rod 6, causing the limiting rod 6 to apply pressure to the elastic element 5 again, making the limiting rod 6 abut against the outer wall of the connecting ring 10. At this time, the connecting head 1 is pulled outward. Due to the friction between the limiting rod 6 and the connecting ring 10, the connecting ring 10 moves from near the sleeve 9 to near the end 7. (Refer to...) Figure 4This allows end 7 to be easily pulled out from sleeve 2. This solution does not require screw riveting, which greatly improves the connection and fixing efficiency of connector 1, and is very convenient for disassembly and assembly.

[0026] Sleeve 2 is threadedly connected to sleeve 3. Sleeve 3 has an annular groove 11, a sealing ring 12, and a gasket 13. The annular groove 11 provides a specific installation position for the sealing ring 12. The sealing ring 12 is usually made of materials with good elasticity and sealing performance, such as rubber or silicone. When sleeve 2 and sleeve 3 are tightened by the threaded connection, the end of sleeve 2 will squeeze the sealing ring 12, causing it to deform elastically and fill the gap between sleeve 2 and sleeve 3, thus forming an effective sealing barrier to prevent external moisture, dust, corrosive gases, and other impurities from entering the cable joint.

[0027] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
