Description

Technical Field

[0001] This application relates to the field of cable fittings, and in particular to a split-type cable connector. Background Technology

[0002] A cable joint, also known as a cable termination, is a component used to connect cable segments into a continuous line after the cable has been laid. These connecting components are called cable joints. Currently, to improve cable laying efficiency, prefabricated joints are commonly used. After the cable is laid, simply connect the ends of adjacent cable segments to the prefabricated joint.

[0003] However, on the one hand, since prefabricated cable joints are usually cold-shrink parts that have undergone expansion processing, they are prone to expansion again during storage or use, leading to stress relaxation in the cable joints. This greatly affects the storage and use of the cable joints. On the other hand, during installation, the cable joint needs to be pre-fitted onto one of the cable sections away from the end. Only after the ends of the two cable sections are crimped together can it be moved back and installed opposite the two ends. This is not only time-consuming and labor-intensive, but the cable joint is also prone to damage to the cable during the movement. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides a split-type cable connector.

[0005] This application provides a split-type cable connector using the following technical solution:

[0006] A split-type cable connector includes a detachable insulating sleeve, two stress cones, and a connecting tube. The insulating sleeve has a first inner cavity. The two stress cones are respectively accommodated at both ends of the first inner cavity. The connecting tube is accommodated in the first inner cavity, and its two ends are respectively used to connect to the two stress cones.

[0007] By adopting the above technical solution, the insulating sleeve, stress cone, and connecting pipe can be installed on the cable in sequence and then assembled relative to each other, eliminating the need for pre-expansion processing of the cable joint and effectively solving the stress relaxation problem caused by the expansion of the cable joint. At the same time, when installed relative to the cable, the insulating sleeve, stress cone, and connecting pipe can be installed in sequence and then assembled relative to each other, eliminating the need to move the cable joint as a whole, which not only saves time and effort but also prevents damage to the cable.

[0008] In one specific implementation, a snap-fit ​​portion is provided in the first inner cavity, the snap-fit ​​portion having a second inner cavity, and the ends of the two stress cones that are close to each other can be accommodated at both ends of the second inner cavity.

[0009] By adopting the above technical solution, the two stress cones can be engaged with the snap-fit ​​part, which effectively improves the assembly strength of the cable joint.

[0010] In one specific implementation, the snap-fit ​​portion is integrally formed with the insulating sleeve.

[0011] By adopting the above technical solution, the snap-fit ​​part can be processed integrally with the insulating sleeve, which effectively reduces the processing difficulty of the snap-fit ​​part.

[0012] In one specific implementation, a limiting ring is provided in the second inner cavity. The limiting ring is deformably configured such that the ends of the two stress cones that are close to each other can respectively abut against the two ends of the limiting ring.

[0013] By adopting the above technical solution, the limiting ring can limit the two stress cones, preventing them from being too close and affecting their stress conduction effect on the cable; at the same time, the deformable limiting ring facilitates the passage of the stress cones, reducing the assembly difficulty between the insulation sleeve and the stress cones.

[0014] In one specific implementation, the second inner cavity includes an inner cavity a formed within the limiting ring and two inner cavities b formed on opposite sides of the axial direction of the limiting ring. The diameter of the inner cavity a is smaller than the diameter of the inner cavity b, and the two stress cones are respectively accommodated in the two inner cavities b at their close proximity ends.

[0015] In one specific implementation, the two cavities b are symmetrically arranged about the cavity a.

[0016] By adopting the above technical solution, the two stress cones can be symmetrically assembled in the insulating sleeve, which effectively improves the stress dissipation effect of both on the cable.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. The insulating sleeve, stress cone, and connecting tube can be installed sequentially on the cable and then assembled relative to each other, eliminating the need for pre-expansion processing of the cable joint and effectively solving the stress relaxation problem caused by expansion of the cable joint;

[0019] 2. When installed opposite to the cable, the insulating sleeve, stress cone and connecting pipe can be installed in sequence and then assembled relative to each other, without the need to move the cable joint as a whole. This not only saves time and effort, but also avoids damage to the cable. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] See Figure 1-5 As shown, a split-type cable connector is shown, including a detachable insulating sleeve 1, two stress cones 2 and a connecting tube 3. The insulating sleeve 1 has a first inner cavity 4 coaxially formed inside, with openings at both ends of the first inner cavity 4. The two stress cones 2 can be accommodated at both ends of the first inner cavity 4, and the connecting tube 3 can be accommodated in the first inner cavity 4, with its two ends being used to connect to the two stress cones 2 respectively.

[0029] The split cable connector in this embodiment, such as Figure 2-3 As shown, before being installed opposite to cable 100, the insulating sleeve 1, stress cone 2, and connecting pipe 3 are relatively separate. They can be sequentially installed onto cable 100 and then assembled relative to each other. Since the two stress cones 2 and the connecting pipe 3 can connect the ends of the two cable sections, and the insulating sleeve 1 and the two stress cones 2 can fit tightly together, the installation strength of the cable joint on cable 100 in this embodiment can be guaranteed. The insulating sleeve 1, stress cone 2, and connecting pipe 3 do not require pre-expansion processing, effectively solving the problem of stress relaxation caused by the cable joint expanding again during storage and use. However, when installing the split-type cable joint opposite to cable 100, as... Figure 4-5 As shown, the insulating sleeve 1, stress cone 2, and connecting pipe 3 can be installed sequentially and then assembled relative to each other. The ends of the two cable sections 100 can be connected through the stress cone 2 and connecting pipe 3. Then, the cable joint can be installed by moving the insulating sleeve 1. Since the diameter of the first inner cavity 4 is larger than the diameter of the cable 100, moving the insulating sleeve 1 not only saves time and effort but also does not damage the cable 100.

[0030] In this embodiment, as Figure 1-3 As shown, a snap-fit ​​part 5 is provided in the first inner cavity 4, and the snap-fit ​​part 5 is integrally formed with the insulating sleeve 1. The snap-fit ​​part 5 has a second inner cavity 6, and both ends of the second inner cavity 6 also have openings. The ends of the two stress cones 2 that are close to each other can be accommodated at the two ends of the second inner cavity 6. The two stress cones 2 can snap against the snap-fit ​​part 5, which effectively improves the assembly strength of the cable joint.

[0031] In this embodiment, a limiting ring 7 is provided in the second inner cavity 6. The limiting ring 7 is a deformable rubber material integrally formed with the snap-fit ​​part 5. The ends of the two stress cones 2 that are close to each other can respectively abut against the two ends of the limiting ring 7. The limiting ring 7 can limit the two stress cones 2 inserted into the second inner cavity 6, preventing the two stress cones 2 from being too close and affecting their stress conduction effect on the cable 100. At the same time, when the insulating sleeve 1 and the stress cones 2 are assembled relative to each other, the deformable limiting ring 7 facilitates the passage of the stress cones 2, reducing the assembly difficulty between the insulating sleeve 1 and the stress cones 2.

[0032] In this embodiment, the second inner cavity 6 includes an inner cavity a61 formed within the limiting ring 7 and two inner cavities b62 respectively formed on both sides of the axial direction of the limiting ring 7. The diameter of the inner cavity a61 is smaller than the diameter of the inner cavity b62, and the ends of the two stress cones 2 that are close to each other can be accommodated in the two inner cavities b62. The two inner cavities b62 are symmetrically arranged about the inner cavity a61. The two stress cones 2 can be symmetrically assembled in the insulating sleeve 1, which effectively improves the stress conduction effect of both on the cable 100.

[0033] The implementation principle of a split-type cable connector according to an embodiment of this application is as follows:

[0034] When installing a cable joint between two cable segments 100, first, put the insulating sleeve 1 on one of the cable segments 100, then move the insulating sleeve 1 away from the end of the cable 100, then install the two stress cones 2 on the ends of the two cable segments 100 respectively, connect the two ends of the connecting pipe 3 to the two stress cones 2 respectively, and finally move the insulating sleeve 1 toward the end of the cable 100 and assemble it with the two stress cones 2.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
