Such repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0039] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0040] As Figure 1 , Figure 2 and Figure 3 shown, an embodiment of the present utility model provides a cable wiring device, including: a first connector 1, a second connector 2, two fixing plates 3, a plurality of positioning protrusions 4, an adjusting member 5, and a sealing assembly 6.

[0041] A first mounting through hole 11 is provided in the middle of the first connector 1, and two first adjusting screw holes 12 communicating with the first mounting through hole 11 are provided on the side wall of the first connector 1. A second mounting through hole 21 is provided in the middle of the second connector 2, and two second adjusting screw holes 22 communicating with the second mounting through hole 21 are provided on the side wall of the second connector 2. A fixing hole 31 for fixing the cable is formed in the middle of the two fixing plates 3 that are fitted together. After the two fixing plates 3 are fitted together, one end of the fixing plates 3 is located in the first mounting through hole 11, and the other end is located in the second mounting through hole 21. A plurality of positioning protrusions 4 are evenly arranged on the side of the fixing plate 3 away from the first connector 1 or the second connector 2, and a clearance groove 41 is provided between two adjacent positioning protrusions 4. The adjusting member 5 abuts against the fixing plate 3 through the first adjusting screw hole 12 and the second adjusting screw hole 22. The sealing component 6 is arranged in the first mounting through hole 11 and the second mounting through hole 21. When the two fixing plates 3 are fitted together, the positioning protrusions 4 on the fixing plates 3 are arranged alternately; when the two relatively installed adjusting members 5 move relative to each other, the positioning protrusions 4 on the two fixing plates 3 are embedded in the giving way grooves 41 .

[0042] When in use, first expose the wire ends at the connection points at both ends of the cable, then put the first connector 1 and the second connector 2 on the two cables respectively, then wrap the exposed wire ends together, and place them on the positioning protrusions 4 after wrapping, then snap the fixing plate 3 at the other end so that the cable is fixed between the positioning protrusions 4, then insert one end of the fixing plate 3 into the first mounting through hole 11 of the first connector 1, and then insert the other end into the second mounting through hole 21 of the second connector 2. After installation, the first connector 1 and the second connector 2 are fixed together by bolts. When the first connector 1 and the second connector 2 are connected, the positions of the two positioning protrusions 4 can be adjusted by the adjusting member 5 so that the positioning protrusions 4 on both sides press the connectors of the cables, and a sealing component 6 is set in the first connector 1 and the second connector 2. The sealing component 6 can reduce the probability of dust and water entering the wiring device during use.

[0043] More specifically, the position of the positioning protrusions 4 can be adjusted by the adjusting member 5 so that the staggered positioning protrusions 4 can be inserted into their corresponding grooves, so that the spacing between the positioning protrusions 4 on both sides becomes smaller. When the spacing between the positioning protrusions 4 is reduced, the cable is fixed between the positioning protrusions 4, avoiding displacement of the cable during use, resulting in the connection falling off.

[0044] In another embodiment, if Figure 4 and Figure 5As shown, in order to prevent the fixing plate 3 from rotating within the first connector 1 and the second connector 2 during use, which may cause the cable connection to become loose, positioning chutes are provided on the inner walls of both the first connector 1 and the second connector 2, and limiting protrusions 32 that cooperate with the positioning chutes are provided on the fixing plate 3. The rotation of the fixing plate 3 is restricted by the positioning chutes and the positioning protrusions 4, thereby increasing the service life after the cable is connected.

[0045] In another embodiment, to prevent electric leakage during use, both the fixing plate 3 and the positioning protrusions 4 are made of insulating materials.

[0046] In another embodiment, as Figure 3 shown, the sealing assembly 6 includes: a plurality of one-way flaps 61. One end of each of the plurality of one-way flaps 61 is stacked in a ring shape in sequence on the inner side wall of the first connector 1 or the second connector 2, and the other end of the one-way flap 61 converges radially.

[0047] The one-way flaps 61 are provided to facilitate the passage of the cable. After the cable passes through, the one-way flaps 61 will automatically adhere to the outer side wall of the cable's insulating layer, improving the sealing performance of the wiring device. At the same time, the contact between the one-way flaps 61 and the cable's insulating layer can also reduce the problem of cable displacement during use. It should be noted that if the cable is displaced, it may cause the connection at the wire end to become loose, resulting in poor contact.

[0048] In another embodiment, the thickness of the one-way flap 61 at the end connected to the first connector 1 and the second connector 2 gradually decreases towards the end away from the connection. To make it more convenient for the cable to pass through the sealing assembly 6, the thickness of the one-way flap 61 at the end away from the connection of the sealing assembly 6 is less than its thickness at the connection.

[0049] In another embodiment, to improve the insulation performance of the wiring device, the one-way flap 61 is made of rubber.

[0050] In another embodiment, to facilitate adjusting the position of the positioning protrusions 4 during use, the fixing plate 3 is arc-shaped, and the included angle between the two sides of the fixing plate 3 is 120 degrees - 160 degrees.

[0051] In another embodiment, as Figure 3 and Figure 4 shown, the positioning protrusion 4 is a semi-circular plate. The arc-shaped side of the positioning protrusion 4 is connected to the fixing plate 3, and a bayonet 42 is provided at one end of the straight side of the positioning protrusion 4. The positioning protrusion 4 is set as a semi-circular plate to facilitate adjusting the distance between the bayonets 42 of the two positioning protrusions 4 and prevent the cable from sliding within the wiring device after being connected.

[0052] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
