Technical Field
[0001] This utility model belongs to the field of power engineering, and in particular relates to a protective shell for preventing accidental contact of power connection hardware. Background Technology
[0002] Electrical connection hardware is a key connecting component in power engineering, widely used in power transmission and distribution systems. It primarily serves to provide electrical connections and mechanical fixation between conductors, and between conductors and equipment or towers. Its performance directly affects the safe and stable operation of the power system.
[0003] However, in practical applications, some electrical connection hardware is exposed to the external environment for a long time, making it susceptible to environmental factors such as dust, moisture, and salt spray, which can lead to problems such as increased contact resistance, metal corrosion, or localized overheating. At the same time, exposed live hardware poses a high safety risk. Accidental contact by personnel or foreign objects may cause electric shock, short circuit, or arc discharge, threatening personal safety and power supply reliability.
[0004] Therefore, there is a particular need for a protective housing to prevent accidental contact of electrical connection hardware in order to solve the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of exposed power connection hardware being susceptible to environmental corrosion and posing a risk of accidental contact, which affects safety and power supply reliability, this utility model provides a protective shell for power connection hardware to prevent accidental contact.
[0006] This utility model is achieved through the following technical means: a protective shell for preventing accidental contact of electrical connection fittings, comprising a mounting plate, a retaining seat, a fixing ring, a guide rod, a sliding ring, a connecting plate, and an adjusting rod II. A retaining seat is fixedly connected to the front of the mounting plate. Two fixing rings arranged side-by-side are slidably arranged at the front of the mounting plate. Two guide rods are fixedly connected to both sides of the front of the mounting plate. A sliding ring is slidably arranged between two adjacent guide rods, with the sliding ring located in front of the corresponding fixing ring. A connecting plate is fixedly connected between the tops of the two sliding rings. An adjusting rod II is rotatably arranged at a high point at the front of the mounting plate, passing through the connecting plate and connecting to the fixing ring. The mounting plate, mounting plate, retaining seat, fixing ring, guide rod, sliding ring, connecting plate, and adjusting rod 2 together constitute the power connection hardware. It also includes a frame, protective frame, guide seat, retaining seat, retaining rod, and positioning component. The front of the mounting plate is fixedly connected to the frame, and the front of the frame is rotatably equipped with the protective frame. The protective frame and the frame together cover the retaining seat, fixing ring, guide rod, sliding ring, connecting plate, and adjusting rod 2. The guide seat is installed at the middle of the bottom of the protective frame, and the retaining seat is installed at the bottom of the frame. The retaining seat is located behind the guide seat, and the retaining rod is slidably mounted on the guide seat. One end of the retaining rod is inserted into the retaining seat.
[0007] As an improvement to the above solution, a positioning component is provided between the guide seat and the locking rod. The positioning component includes a positioning rod. The front part of the guide seat has two notches, No. 1 and No. 2. No. 1 is located behind No. 2. The end of the locking rod away from the locking seat is fixedly connected to the positioning rod, and the positioning rod is inserted into the right notch No. 1.
[0008] As an improvement to the above solution, it also includes a buffer block, an adjusting rod, and a limiting rod. Two symmetrically arranged limiting rods are slidably arranged on each sliding ring. A buffer block is fixed between the two limiting rods on the same sliding ring. The buffer block is slidably engaged with the corresponding sliding ring. An adjusting rod is threaded on each sliding ring. The rear end of the adjusting rod near the mounting plate is rotatably connected to the corresponding buffer block.
[0009] As an improvement to the above solution, an observation panel is also included, with the observation panel embedded in the front of the protective frame.
[0010] As an improvement to the above solution, it also includes hanging rings, with hanging rings fixed to both sides of the upper part of the mounting plate.
[0011] As an improvement to the above scheme, handwheels are fixedly provided at the front ends of both adjusting rod one and adjusting rod two away from the mounting plate.
[0012] Beneficial effects: 1. By setting up a frame, protective frame, guide seat, card seat, card rod, card seat and positioning component, the components set on the mounting plate can be effectively shielded, avoiding these components from being exposed to harsh environments such as dust, moisture, and salt spray, thereby reducing the risk of corrosion, increased contact resistance and local overheating. At the same time, it prevents accidental contact by personnel or foreign objects, significantly reducing the probability of accidents such as electric shock, short circuit or arc discharge, and improving personal safety and power supply reliability.
[0013] 2. Through the cooperation of the buffer block, adjusting rod 1 and limiting rod, a controllable secondary clamping force can be applied on the basis of the initial clamping of the wire by the sliding ring and the fixed ring, so as to further improve the stability and reliability of clamping.

Detailed Implementation
[0021] Example: A protective housing for preventing accidental contact of electrical connection hardware, such as... Figures 1-6 As shown, the device includes a mounting plate 1, a mounting base 8, a fixing ring 9, a guide rod 10, a sliding ring 11, a connecting plate 15, an adjusting rod 16, and a hanging ring 17. The mounting plate 1 is fixedly connected to the front of the mounting plate 1. Two fixing rings 9 are slidably arranged side-by-side at the front of the mounting plate 1. Two guide rods 10 are fixedly connected to the left and right sides of the front of the mounting plate 1. A sliding ring 11 is slidably arranged between two adjacent guide rods 10, with the sliding ring 11 located in front of the corresponding fixing ring 9. A connecting plate 15 is fixedly connected between the tops of the two sliding rings 11. An adjusting rod 16 is rotatably arranged at the high point of the front of the mounting plate 1. The adjusting rod 16 passes through the connecting plate 15 and is threadedly engaged with the connecting plate 15. A handwheel is fixedly provided at the front end of the adjusting rod 16 away from the mounting plate 1 for easy operation. The mounting plate 1, mounting base 8, fixing ring 9, guide rod 10, and sliding ring 17 are also included. 1. The connecting plate 15 and the adjusting rod 16 together constitute the power connection hardware. The upper left and right sides of the mounting plate 1 are fixedly connected with hanging rings 17 to facilitate the mounting plate 1 to be hung and fixed on the power facilities. It also includes a frame 2, a protective frame 3, an observation plate 4, a guide seat 5, a locking seat 6, a locking rod 7 and a positioning component. The front of the mounting plate 1 is fixedly connected to the frame 2. The front of the frame 2 is rotatably set with the protective frame 3. The protective frame 3 and the frame 2 together cover the locking seat 8, the fixing ring 9, the guide rod 10, the sliding ring 11, the connecting plate 15 and the adjusting rod 16. The observation plate 4 is embedded in the front of the protective frame 3. The guide seat 5 is fixed to the middle of the bottom of the protective frame 3 by bolts. The bottom of the frame 2 is fixed with the locking seat 6 by bolts. The locking seat 6 is located behind the guide seat 5. The locking rod 7 is slidably set on the guide seat 5. The rear end of the locking rod 7 is inserted into the locking seat 6.
[0022] like Figure 3As shown, a positioning component is provided between the guide seat 5 and the locking rod 7. The positioning component includes a positioning rod 71. The front part of the guide seat 5 has two notches 1 51 and two notches 2 52. Notches 1 51 are located behind notches 2 52. The front end of the locking rod 7 away from the locking seat 6 is fixedly connected to the positioning rod 71. The positioning rod 71 is inserted into the right notch 1 51, thereby fixing the position of the locking rod 7 on the guide seat 5 and ensuring that the rear end of the locking rod 7 is stably inserted into the locking seat 6.
[0023] like Figure 4 , Figure 5 and Figure 6 As shown, it also includes a buffer block 12, an adjusting rod 13, and a limiting rod 14. Two symmetrically arranged limiting rods 14 are slidably arranged on each sliding ring 11. A buffer block 12 is fixedly connected between the two limiting rods 14 on the same sliding ring 11. The buffer block 12 is slidably engaged with the corresponding sliding ring 11. An adjusting rod 13 is threaded on each sliding ring 11. The rear end of the adjusting rod 13 near the mounting plate 1 is rotatably connected to the corresponding buffer block 12. A handwheel is also fixedly provided at the front end of the adjusting rod 13 away from the mounting plate 1.
[0024] In use, the operator first rotates the positioning rod 71 clockwise to 90 degrees (with the front of the observation plate 4 as the viewing direction) to disengage the positioning rod 71 from the right notch 1 51. Then, the operator pinches the positioning rod 71 and pulls the locking rod 7 forward to disengage the rear end of the locking rod 7 from the locking seat 6. After disengagement, the operator continues to rotate the positioning rod 71 clockwise to 90 degrees to insert the positioning rod 71 into the left notch 2 52 (or rotates the positioning rod 71 counterclockwise to 90 degrees to insert it into the right notch 2 52), preventing the positioning rod 71 from clashing with the locking rod 7 in subsequent operations. If the wire slips unexpectedly during operation, rotate the protective frame 3 upwards to expose the mounting plate 1. Rotate the adjusting rod 16 clockwise (with the front of the mounting plate 1 as the viewing direction). Driven by the adjusting rod 16, the connecting plate 15 moves the two sliding rings 11 forward along the guide rod 10, increasing the distance between the sliding rings 11 and the fixed rings 9. Then, thread the wire through the left or right side of the frame 2, pulling the wire through the two fixed rings 9 and the two sliding rings 11 in sequence, and securing it with the holder 8. After threading, rotate the adjusting rod 16 counterclockwise to drive the connecting plate 15 to move the two sliding rings 11 backwards, so that the sliding rings 11 and the fixed rings 9 clamp the wire. To further enhance the clamping reliability, rotate the adjusting rod 13 clockwise (with the front of the sliding rings 11 as the viewing direction), moving the buffer block 12 backwards to apply a secondary clamping force to the wire. After clamping, rotate the protective frame 3 downwards. The protective frame 3 and the frame 2 together cover the components on the mounting plate 1. Then, rotate the positioning rod 7 counterclockwise. Rotate the positioning rod 71 from 1 to 90 degrees to disengage it from the left notch 2 52 (or rotate the positioning rod 71 clockwise to 90 degrees to disengage it from the right notch 2 52). Pinch the positioning rod 71 and push the locking rod 7 backward to re-insert the rear end of the locking rod 7 into the locking seat 6. Finally, rotate the positioning rod 71 counterclockwise to 90 degrees to re-insert it into the right notch 1 51 (or rotate the positioning rod 71 clockwise to 90 degrees to insert it into the left notch 1 51), thus firmly locking the protective frame 3 onto the frame 2 and achieving closed protection against accidental contact.
