All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1

[0022] Please see Figures 1 to 2 This utility model provides a technical solution: a wiring assembly for oilfield drilling and control equipment, including a junction box 1, with terminals 18 on the surface of the junction box 1, a sealing cover 2 embedded on the surface of the junction box 1, sliding plates 4 slidably connected to both ends of the surface of the sealing cover 2, a stop block 12 inserted into one end of the surface of the sliding plate 4, the stop block 12 pressing against the surface of the junction box cover 1, multiple insert plates 7 slidably connected to the surface of the terminals 18, a rubber sleeve 15 covering the surface of the insert plates 7, and an arc plate 14 fixedly connected to one end of the insert plates 7. A sliding plate 4 and a fixing plate 5 are provided on the surface of the sealing cover 2, and a retractable stop block 12 is provided on the surface of the fixing plate 5, allowing the stop block 12 to pass through the surface of the junction box 1 for quick sealing. This makes the wiring assembly easier and faster to install and disassemble, improving the maintainability of the equipment. Through the cooperation between the insert plates 7, the arc plate 14, and the rubber sleeve 15, the wiring can be clamped and fixed, improving the strength of the wiring and ensuring the stability and accuracy of signal transmission.

[0023] Example 2

[0024] Please see Figures 1 to 3, on the basis of Embodiment 1, in order to achieve the quick fixation and disassembly between the junction box body 1 and the sealing cover 2, fixing grooves 8 are formed on the two end surfaces of the junction box body 1. The fixing grooves 8 are square grooves. A "hui"-shaped groove is provided on the top surface of the junction box body 1. The height of the groove is the same as the surface height of the sealing cover 2. A rubber pad 6 is fixedly connected to the surface of the groove. The rubber pad 6 is clamped between the junction box body 1 and the sealing cover 2. The rubber pad 6 is provided to prevent gaps at the connection between the junction box body 1 and the sealing box body 2, improving the waterproof and moisture-proof properties. Sliding grooves 3 are formed on the two end surfaces of the sealing cover 2. A sliding plate 4 is slidably connected to the surface of the sliding groove 3. The sliding plate 4 is in a square plate-like structure. A limiting groove 10 is formed on the surface of the sliding plate 4. The limiting groove 10 is an arc-shaped groove at one end. The width of the limiting groove 10 is greater than the length of the fixing plate 5. A limiting rod 11 penetrates through the surface of the limiting groove 10;

[0025] The limiting rod 11 can slide in the limiting groove 10 to limit the sliding range of the sliding plate 4. The limiting rod 11 is in a cylindrical structure. The limiting rod 11 is fixedly connected between the two ends of the sliding groove 3. Fixing plates 5 are fixedly connected to the surfaces of the two sliding grooves 3 away from each other. The fixing plates 5 are in a square plate-like structure. The fixing plates 5 penetrate through the surfaces of the fixing grooves 8. A retaining groove is formed on the surface of the fixing plate 5. A rubber block 13 is fixedly connected to the central position of the surface of the retaining groove. Two retaining blocks 12 are respectively fixedly connected to the two end surfaces of the rubber block 13. One end of the retaining block 12 has an inclined surface. When one end of the inclined surface of the retaining block 12 is squeezed by the surface of the junction box body, the retaining block 12 squeezes the rubber block 13 from the original state to the compressed state, and the retaining block 12 thus enters the retaining groove. Until the fixing plate 5 penetrates through the fixing groove 8, the rubber block 13 returns from the compressed state to the original state, and the retaining block 12 is ejected to press against the surface of the junction box 1.

[0026] Embodiment 3

[0027] Please refer to Figures 1 to 5Based on Embodiment 2, in order to clamp the wires connected in the wire holes 9, the surface of the terminal 18 is integrally formed with multiple wire holes 9, and the surface of the terminal 18 has multiple circular holes that communicate with the wire holes 9. A rubber groove 17 is formed on the surface of the circular hole. The rubber groove 17 is circular, and its diameter is larger than the diameter of the circular hole. The insert plate 7 passes through the surface of the circular hole, and the cover plate 16 slides in the rubber groove 17, which can pull the rubber sleeve 15. The insert plate 7 has a T-shaped circular plate structure, and the cover plate 16 is fixedly connected to the surface of the insert plate 7. The cover plate 16 has an annular plate structure. The two ends of 5 are fixedly connected to the surfaces of the rubber groove 17 and the cover plate 16, respectively. When the rubber sleeve 15 is in its original state, the arc plate 14 is in the middle part of the wire hole 9. When the insert plate 7 is pulled upward, the rubber sleeve 15 changes from its original state to a stretched state and tends to spring back downward. When the insert plate 7 is released, the rubber sleeve 15 loses its tension and returns to its original state from the stretched state, thereby moving the arc plate 14 downward from the top surface of the wire hole 9 and clamping it on the surface of the wire. The bottom end of the arc plate 14 is provided with multiple arrays of protrusions. The protrusions can increase the friction between the arc plate 14 and the wire, making the arc plate 14 clamp the wire more firmly.

[0028] In actual use, firstly, move the insert plate 7 upwards along the rubber groove 17, slide the cover plate 16 along the rubber groove 17, and slide the arc plate 14 to the upper end of the wire hole 9. The slide plate 16 drives the rubber sleeve 15 from its original state to a stretched state. Then, pass the wire through the wire hole 9 and connect and fix it to the connection end at the center of the terminal 18. After fixing, release the insert plate 7, the rubber sleeve 15 loses tension and returns to its original state from the stretched state. The arc plate 14 moves downwards from the top surface of the wire hole 9 and clamps the surface of the wire. The protrusions on the surface of the arc plate 14 and the wire surface... The surface contacts the junction box, increasing the friction with the wiring surface. Then, the sealing box cover 2 is placed on the surface of the junction box body 1. The cover plate 4 is slid to both ends. When one end of the inclined surface of the stop block 12 is squeezed by the surface of the junction box body, the stop block 12 squeezes the rubber block 13 from its original state to a compressed state. The stop block 12 is then placed in the retaining groove. After the fixing plate 5 passes through the fixing groove 8, the rubber block 13 returns to its original state from the compressed state, and the stop block 12 is ejected to press against the surface of the junction box 1, completing the sealing of the wiring. When disassembly is required, simply press the stop blocks 12 on both sides back into the retaining groove.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
