Description

Technical Field

[0001] The utility model relates to the field of cable joints, and particularly relates to a waterproof structure for the cable part of a cable joint. Background Art

[0002] Cable joints are divided into a joint part and a cable part, which are structures used to connect adjacent cable bodies and belong to a part of the cable. When connecting cables, adjacent cable bodies are connected through the joint part. In order to ensure the waterproof performance after connection, a waterproof protective sleeve is usually arranged on the joint part to achieve waterproofing.

[0003] When the existing cable joints are in use, after the cable bodies are connected through the joint part, only a waterproof structure is arranged on the joint part. For the cable part, no waterproof structure is provided. In a humid environment, there are gaps at the part where the cable part is connected to the joint part, and moisture easily enters the joint interior through the gaps, thereby causing connection failures of the joint and affecting the connection effect of the entire cable. In some cable joints, waterproof tapes are arranged between the joint part and the cable part, but the waterproof effect of the waterproof tapes is average and they cannot play a role in relative fixation, resulting in poor use effects.

Detailed implementation manners

[0017] To make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0018] As Figures 1 - 4 shown, a waterproof structure for the cable part of a cable joint includes a joint body 1 and a cable body 2. The joint body 1 is connected to the cable body 2. A connecting head 5 and a limiting insertion plate 6 are provided on the joint body 1. A waterproof structure 3 connected to the connecting head 5 is provided on the cable body 2. A contact head 4 is provided on the joint body 1, and the contact head 4 is electrically connected to the wire inside the cable body 2. An insertion ring 7 is provided on the limiting insertion plate 6, and the limiting insertion plate 6 and the insertion ring 7 are connected inside the waterproof structure 3.

[0019] When using the cable, a waterproof structure 3 is provided at the connection between the cable part and the joint part of the cable joint. The waterproof structure 3 is fixed to the joint body 1 through the connecting head 5. The limiting insertion plate 6 and the insertion ring 7 are inserted into the waterproof structure 3 to play a sealing role. At the same time, the waterproof structure 3 is relatively fixed with the cable body 2, thereby ensuring that the cable body 2 and the joint body 1 are relatively fixed, and the situation of loose connection between the cable body 2 and the joint body 1 can be avoided, guaranteeing the use effect of the cable joint.

[0020] Through the above implementation, the waterproof structure 3 includes a waterproof cover 301, a slot 303, a sealing gasket 304, a fastening assembly 306, and a locking member 307. The slot 303 is formed on the waterproof cover 301. The sealing gasket 304 is disposed in the slot 303 on the waterproof cover 301. The fastening assembly 306 is fixed on the waterproof cover 301. The locking member 307 is connected to the fastening assembly 306. The waterproof structure 3 further includes a threaded groove 302, an annular groove 305, and a rubber seal 308. The threaded groove 302 is formed on the waterproof cover 301, and the waterproof cover 301 is threadedly connected to the connector 5 through the threaded groove 302. The annular groove 305 is formed on the sealing gasket 304, and the sealing gasket 304 is connected to the insertion ring 7 through the annular groove 305. The rubber seal 308 is disposed inside the waterproof cover 301 and is in close contact with the cable body 2. The rubber seal 308 is composed of a rubber sleeve and a rubber pad. The rubber sleeve is inserted at a position inside the waterproof cover 301 near the fastening assembly 306. The locking member 307 is threadedly connected to the fastening assembly 306. The fastening assembly 306 includes a threaded joint 3061, a clamping groove 3062, a square hole 3063, a deformable inner lining 3064, a clamping ring 3065, an elastic pressing piece 3066, and a pressing head 3067. The clamping groove 3062 and the square hole 3063 are formed on the threaded joint 3061. The deformable inner lining 3064 is fixedly connected to the clamping ring 3065 and is disposed inside the threaded joint 3061. The clamping ring 3065 is connected in the clamping groove 3062. The elastic pressing piece 3066 and the pressing head 3067 are fixedly connected, and the end of the elastic pressing piece 3066 is connected to the deformable inner lining 3064. The elastic pressing piece 3066 passes through the square hole 3063, and there is a small gap between the pressing head 3067 and the deformable inner lining 3064.

[0021] Through the provided waterproof structure 3, connector 5, limit insertion plate 6, and insertion ring 7, the waterproof structure 3 is threadedly connected to the connector 5. The limit insertion plate 6 is located in the slot 303, and the insertion ring 7 is connected within the annular groove 305 on the gasket 304, which can waterproof the connection part between the joint body 1 and the cable body 2, ensuring good waterproof performance for the cable part of the cable joint. By using the fastening assembly 306 and locking member 307, structures such as a deformable inner lining 3064, elastic pressing piece 3066, and pressing head 3067 are provided in the fastening assembly 306. After the locking member 307 is screwed onto the threaded joint 3061, a force is exerted on the elastic pressing piece 3066, causing the pressing head 3067 to abut against the deformable inner lining 3064 and exert a force, fixing the deformable inner lining 3064 to the cable body 2, which can relatively fix the cable body 2 and the joint body 1, preventing loosening of the connection between the cable body 2 and the joint body 1. A rubber seal 308 is provided inside the waterproof cover 301, and the rubber seal 308 is in close contact with the cable body 2, further improving the sealing performance and preventing moisture from entering the waterproof cover 301 from the fastening assembly 306, ensuring the waterproof effect.

[0022] When connecting the waterproof structure 3, the waterproof cover 301 is installed onto the connector 5 through the threaded groove 302. The end of the connector 5 abuts against the rubber seal 308. The limit insertion plate 6 is inserted into the slot 303 and abuts against the gasket 304. At the same time, the insertion ring 7 is connected into the annular groove 305. Subsequently, the locking member 307 is screwed onto the threaded joint 3061 in the fastening assembly 306. As the locking member 307 rotates and displaces, the locking member 307 exerts a force on the elastic pressing piece 3066, causing the elastic pressing piece 3066 to deform and drive the pressing head 3067 to move. When the pressing head 3067 contacts the deformable inner lining 3064, the deformable inner lining 3064 is stressed and undergoes slight deformation, thereby clamping onto the cable body 2. In this way, the entire waterproof structure 3 and the cable body 2 are fixed together. After the waterproof structure 3 is installed and used, during the use process, the waterproof cover 301 is located at the position where the cable body 2 is connected to the joint body 1, serving a waterproof function. The connector 5 abuts against the rubber seal 308, causing the rubber seal 308 to deform and thus contact the cable body 2 more tightly, which can achieve a good sealing effect at the fastening assembly 306, preventing moisture from entering the inside of the waterproof cover 301 from the fastening assembly 306. The limit insertion plate 6 abuts against the gasket 304, and the insertion ring 7 is located in the annular groove 305, which can seal one end of the waterproof cover 301 close to the joint body 1, ensuring the waterproof effect of the waterproof structure 3. The fastening assembly 306 is fixed to the cable body 2, and the entire waterproof structure 3 fixes the joint body 1 and the cable body 2 together, which can achieve an anti-pulling effect and prevent the cable body 2 and the joint body 1 from coming into contact and loosening, ensuring the use effect.
