It mainly consists of overhead lines, cables, poles, distribution transformers, disconnect switches, reactive power compensators, and some auxiliary facilities. For some broken cables, in order to reduce waste of resources, a wiring device is needed to connect the two cables.

[0003] Cables usually use copper or aluminum as the cable core, and an insulating layer is wrapped outside the cable core. Currently, when connecting two cables, the insulating layers at the ends of the two cable segments are usually peeled off to expose the cable cores inside, and then the two cable cores are wound and twisted together, and then wrapped with electrical tape. However, the connected cable is prone to be pulled under the influence of the environment, resulting in the twisting joint not being firm enough and breaking, which not only fails to meet the normal power supply requirements but also increases the number of maintenance times. Summary of the Utility Model

Detailed implementation mode

[0023] The technical solutions in the present invention will be further described below in conjunction with the drawings and embodiments.

[0024] As Figures 1 to 3 shown, an embodiment of the present invention provides a rapid wiring device for a distribution network, which is used to connect the cable 1 and includes:

[0025] A wiring cylinder 2 having a channel passing through its interior, and two cables 1 are respectively inserted through both ends of the channel;

[0026] A fixing assembly, a plurality of notches 401 are opened at both ends of the wiring cylinder 2, the fixing assembly includes a plurality of elastic blocks 402 arranged in the plurality of notches 401 and an adjusting member sleeved on the end of the wiring cylinder 2, the adjusting member abuts against the plurality of elastic blocks 402, and when the adjusting member moves along the axis direction of the wiring cylinder 2, the ends of the plurality of elastic blocks 402 are made to approach each other and abut against the surface of the cable 1.

[0027] In the embodiment of the present invention, the wiring cylinder 2 has a channel, and the channel passes through both ends thereof, so that the wiring cylinder 2 forms a hollow cylindrical structure. When connecting two cables 1, first twist the ends of the two cables 1, and after twisting, the connection point can be wrapped with a heat shrinkable tube or adhesive tape. After the operation, slide the wiring cylinder 2 to the twisting part, so that the twisting part is located in the middle of the wiring cylinder 2, and operate the adjusting member, so that the adjusting member moves along the axis direction of the wiring cylinder 2 to the end of the wiring cylinder 2, so that the inner side of the wiring cylinder 2 presses on each elastic block 402. The initial state of the elastic block 402 is a state where the end extends outwards. Under the extrusion of the wiring cylinder 2, the ends of each elastic block 402 approach each other and abut against the surface of the cable 1, pressing and fixing the cable 1 located in the wiring cylinder 2. Even if the cable 1 outside the wiring cylinder 2 is pulled, the stable mechanical connection provided by the elastic block 402 can ensure the firmness of the twisted joint of the cable 1, effectively preventing poor contact or separation of the cable 1 caused by external pulling or vibration; at the same time, the wiring cylinder 2 can also provide physical protection for the twisted joint, reducing the influence of bad weather conditions on the connection point, thereby extending the service life of the connection point.

[0028] Based on the above solution, as Figure 1 And Figure 3As shown in the figure, the adjusting member includes a first adjusting cylinder 3 sleeved on the end of the wiring cylinder 2 and abutted against a plurality of elastic blocks 402. A first thread section 4 is provided at the end of the wiring cylinder 2, and the first thread section 4 extends to the end of the first adjusting cylinder 3. The first adjusting cylinder 3 is threadedly connected to the first thread section 4.

[0029] Specifically, when pressing and fixing the cable 1 through the action of the adjusting member, by rotating the first adjusting cylinder 3, the first thread section 4 is driven to move under the action of the internal thread. In the initial state, the first adjusting cylinder 3 does not contact each elastic block 402. When the first adjusting cylinder 3 moves a certain position, the elastic end of the elastic block 402 abuts against the inner wall of the first adjusting cylinder 3. Under the continuous movement of the first adjusting cylinder 3, the other end of the elastic block 402 gradually moves into the notch 401 until the other end of the elastic block 402 abuts against the surface of the cable 1, and the first adjusting cylinder 3 is self-locked under the action of the first thread section 4, that is, the pressing and fixing of the cable 1 is completed.

[0030] Specifically, as Figure 3 shown, limit blocks 404 are provided at both ends of the wiring cylinder 2 to limit the axial movement of the first adjusting cylinder 3; under the action of the limit blocks 404, the axial movement range of the first adjusting cylinder 3 can be limited, and accidental detachment of the first adjusting cylinder 3 during operation can be avoided, thereby ensuring the safety of the connection.

[0031] Specifically, as Figure 3 shown, an anti-slip pad 403 is provided at the end of the elastic block 402, and the anti-slip pad 403 abuts against the surface of the cable 1; under the action of the anti-slip pad 403, the friction between the elastic block 402 and the surface of the cable 1 can be increased, so as to ensure that the cable 1 is more firmly fixed in the wiring cylinder 2 and is not likely to slide due to external forces. Moreover, the anti-slip pad 403 is made of silicone rubber, which can avoid surface damage that may be caused by the direct contact between the elastic block 402 and the cable 1. Especially when the surface of the cable 1 is soft or has a special coating, the cable 1 can be effectively protected from damage.

[0032] Specifically, as Figure 3 shown, a sealing ring 5 is provided inside the wiring cylinder 2, and the sealing ring 5 abuts against the circumference of the cable 1; the sealing ring 5 can effectively block moisture and dust from entering the inside of the wiring cylinder 2. Especially when used outdoors or in a humid environment, the waterproof ability of the whole device can be significantly improved, preventing moisture and dust from eroding the connection point of the cable 1, thereby avoiding the occurrence of faults.

[0033] Based on the above scheme, as Figure 2As shown in the figure, the wiring cylinder 2 includes two connecting cylinders 20 that are mirror-distributed. The connecting cylinder 20 includes a large cylinder 201 and a small cylinder 202 that are connected to each other. One of the large cylinders 201 is provided with a second threaded section 203, and the other large cylinder 201 is provided with an annular groove 204. A second adjusting cylinder 8 is rotatably arranged in the annular groove 204. When the two large cylinders 201 are butted, the second adjusting cylinder 8 is threadedly connected to the second threaded section 203. Since the diameter of the twisted part of the cable 1 is often larger than the diameter of the cable 1 itself after the cable 1 is twisted, in order to facilitate the installation of the wiring cylinder 2, before the cable 1 is twisted, the two connecting cylinders 20 are respectively sleeved on the two cables 1, and the large cylinders 201 of the two connecting cylinders 20 are made to correspond. After the two cables 1 are twisted, the two connecting cylinders 20 are respectively pushed to move on the cable 1, and the large cylinders 201 of the two connecting cylinders 20 are butted, and the second adjusting cylinder 8 of one of the large cylinders 201 is rotated so that the second adjusting cylinder 8 is threadedly connected to the second threaded section 203, completing the butting of the two connecting cylinders 20 and realizing the assembly of the wiring cylinder 2. And when it is necessary to check the twisted part subsequently, the wiring cylinder 2 can be easily opened to facilitate maintenance work.

[0034] Specifically, as Figure 2 shown, one of the large cylinders 201 is provided with a limiting rod 7, and the limiting rod 7 passes through the other large cylinder 201. When the two large cylinders 201 are butted, the limiting rod 7 of one of the large cylinders 201 is first inserted into the other large cylinder 201, which can ensure that the two large cylinders 201 are correctly aligned when butted, avoid connection problems caused by inaccurate alignment, and can also limit this large cylinder 201 to facilitate the threaded connection between the second adjusting cylinder 8 and the second threaded section 203.

[0035] Specifically, as Figure 4 shown, the end of one of the large cylinders 201 is provided with a sealing layer 6. The sealing layer 6 can ensure the sealing performance after the two connecting cylinders 20 are connected, and also avoid moisture and dust from entering the interior of the wiring cylinder 2 to ensure the sealing performance.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
