Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to a cable joint connection structure. Background Art

[0002] A cable is an important component in power, communication, control signal and other transmission systems. It consists of at least two insulated conductors, which are usually placed in a common sheath or outer protective layer. The cable can transmit electrical energy or signals from one place to another. It is safer and more efficient than a single wire because it reduces the number of exposed conductors and provides additional protection.

[0003] For conventional and short-distance line cables, an integrally formed cable joint structure is mostly adopted to ensure the stability of the connection. For some long-line cables with uncertain distances, cable joints are needed to connect multiple sections of cables. Most of them are directly sleeved outside the connection of two cables, and heat shrinkable sleeves are used to fix the cable head and the cable. When the cable is pulled or dragged multiple times, looseness or even detachment may occur between the cable and the cable joint, resulting in poor contact and affecting signal transmission. Summary of the Utility Model

In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0029] Referring to Figures 1-4 , the present utility model provides a cable joint connection structure, including:

[0030] A main body unit 100, including two sets of cable sleeves 101, and cable cores 102 are fixedly connected inside the two sets of cable sleeves 101;

[0031] A connection unit 200, including a first fixed shell 201 fixedly connected to one set of cable sleeves 101, and turning slots 202 are opened on both the upper and lower sides of the first fixed shell 201. A second fixed shell 214 is provided on one side of the first fixed shell 201, and two connecting rods 204 are rotatably connected to the surface of the second fixed shell 214. The second fixed shell 214 is fixedly connected to the other set of cable sleeves 101 on one side. Two pull rods 203 are rotatably connected inside the two turning slots 202, and receiving rod slots 213 are opened inside the two pull rods 203. The inner wall surfaces of the two receiving rod slots 213 are movably connected to the surfaces of the connecting rods 204. Locking components 206 are provided on both sides of each of the two receiving rod slots 213, and retraction slots 205 are opened on one side of each of the locking components 206. Rotating shafts are fixedly connected to both sides of the two connecting rods 204, and the rotating shafts are rotatably connected to the inner wall surfaces of the locking slots 207.

[0032] Among them, each group of the locking components 206 includes a card plate 206a that is slidably connected to the inner wall surface of the retraction groove 205, and one side of the card plate 206a is movably connected to the inner wall surface of the card slot 207, and the other side of each group of the card plates 206a is inserted and connected with two groups of fixed rods 206c, and the surface of the fixed rods 206c is sleeved with springs 206b, and the two ends of each group of the springs 206b are respectively fixedly connected to the inner wall surface of the retraction groove 205 and the surface of the card plate 206a. Pushed by the elastic force of the spring 206b, the card plate 206a slides out from the inside of the retraction groove 205 and fits with the inner wall of the card slot 207, thereby locking the rotating shaft inside the card slot 207.

[0033] Furthermore, the surfaces of the opposite sides of each group of the clamping plates 206a are designed to be inclined, and the length dimension of each group of the clamping plates 206a is greater than the lateral dimension of the slot 207. When the connecting rod 204 drives the rotating shaft to move inside the slot 207, the inclined design allows the rotating shaft to push the clamping plate 206a to slide into the inside of the retracted slot 205, thereby making the rotating shaft contact with the bottom of the inner wall of the slot 207.

[0034] Furthermore, one end of the two groups of pull rods 203 is rotatably connected to a lever 209, and a soft pad 208 is provided on one side surface of the lever 209. The two groups of soft pads 208 are rotatably connected to the inner wall surface of the flip groove 202. The two groups of soft pads 208 are made of rubber material. The elastic force of the rubber can pop the lever 209 out of the flip groove 202, making it convenient for the staff to pull the pull rod 203.

[0035] Furthermore, a threaded ring 211 is fixedly connected to the surface of the fixed shell 201, and a protective shell 210 is threadedly connected to the surface of the threaded ring 211. The protective shell 210 is slidingly connected to the surface of another cable sleeve 101. The protective shell 210 can be flexibly removed from the surface of the threaded ring 211 by threadedly rotating the protective shell 210.

[0036] Furthermore, a sealing ring 212 is fixedly connected to the side of the protective shell 210 away from the threaded ring 211, and the sealing ring 212 is made of rubber material. The sealing ring 212 is slidably connected to the surface of another cable sleeve 101, has a sealing effect, and plays a role in waterproofing and dustproofing.

[0037] During use, align the fixed housing 1 (201) with the fixed housing 2 (214), move the connecting rod 204 to flip on the surface of the fixed housing 2 (214), and the rotating shaft fixedly connected to the connecting rod 204 slides into the card slot 207. By pushing the inclined card plate 206a, the card plate 206a slides into the inside of the retraction slot 205, so that the rotating shaft is movably connected to the bottom of the inner wall of the card slot 207. Then, the card plate 206a slides out of the inside of the retraction slot 205 under the push of the spring 206b and fits against the inner wall of the card slot 207 to lock the rotating shaft. Then, pull the pull rod 203 to flip into the inside of the retraction rod slot 213. At the same time, drive the connecting rod 204 to move through the rotating shaft, and the fixed housing 2 (214) rotatably connected to the connecting rod 204 closely adheres to and is fixed to the fixed housing 1 (201), tightly connecting the two groups of cable cores 102. Rotate the protective housing 210 so that the protective housing 210 is threadedly connected to the threaded ring 211, which can protect the fixed housing 1 (201) and the fixed housing 2 (214).

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. 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 within the scope of the claims of the present invention.
