Description

Technical Field

[0001] The present invention relates to a connection device, belonging to the technical field of electrical line connection, and in particular to a safety connection device for electrical engineering lines. Background Art

[0002] With the development of society, electrical engineering has developed rapidly. In electrical engineering, the effect of line connection has a key impact on the assembly of electrical engineering equipment or the layout of household wiring. The current method for electricians to connect lines is to first turn off the power, then strip the insulation layer of the wire, and then use a wrench to twist the copper wires of the two wires together, and then wrap them with insulating tape. This method is slow, the connection effect is unstable, and there is a risk of leakage. Another connection method is to use an electrical engineering line connection device to connect the two cables together, but the cable ends and the connection device are easy to separate, so the connection effect is poor.

[0003] A Chinese patent application with application number 202410236162.9 and application date March 1, 2024 discloses a safe connection device for power grid cables, including a junction box, a terminal block fixed inside the junction box, symmetrically distributed terminal holes provided on the side walls of the terminal block, a groove body provided on the inner wall of the terminal hole, a conductor fixed at the bottom of the groove body, a rotating rod passing through the top of the junction box, a turntable fixed at the bottom of the rotating rod, a squeezing mechanism provided at the bottom of the turntable, symmetrically distributed support seats fixed inside the junction box, a pressure plate provided above the support seats, and the pressure plate connected to the rotating rod through a transmission mechanism; although this design can synchronously press the wires against the surface of the conductor, thereby achieving rapid connection of two cables, it still has the following defects:

[0004] In this design, when connecting a disconnected cable, the left branch and the right branch of the cable are connected together. The multiple wires of the left branch will be pressed together, and the multiple wires of the right branch will be pressed together. At this time, the broken connection of the wires will be caused, so a loop will be formed between the wires, and the loop will cause a short circuit problem, so the connection effect in the existing technology is poor.

The position of all the left pressure plates can be adjusted simultaneously by adjusting the left screw, thereby facilitating fixation. The left pressure plate is insulated, so when the left pressure plate presses on the left wire, it will not cause the left wires to be connected through the left pressure plate and the left screw, thereby preventing a short circuit. Therefore, the present invention is easy to fix.

[0030] 3. In an electrical engineering line safety connection device of the present invention, the left insulating column is provided with a left convex ring, and the right insulating column is provided with a right convex ring, and the left convex ring and the right convex ring are fixed by two half-ring clamps; the left insulating column is also covered with a left ring sleeve, and the left ring sleeve is covered with an external threaded sleeve, and the right insulating column is covered with a right ring sleeve, and the right ring sleeve is covered with an internal threaded sleeve, and the internal threaded sleeve is threadedly connected to the external threaded sleeve; the left connecting structure is covered with a left sealing sleeve, and a left waterproof ring is provided between the left sealing sleeve and the left ring sleeve, and the outer cover of the other end of the left sealing sleeve is provided with a left rubber sleeve and a left cone head sleeve, and the right connecting structure is covered with a right sealing sleeve, and a right waterproof ring is provided between the right sealing sleeve and the right ring sleeve, and the outer cover of the other end of the right sealing sleeve is provided with a right rubber sleeve and a right cone head sleeve. The head cover, when used, the left rubber cover and the left cone cover form a seal between the left cable and the left connecting structure, and the right rubber cover and the right cone cover form a seal between the right cable and the right connecting structure. The aforementioned structure not only has a good waterproof effect, but also fixes the position of the left cable and the right cable, preventing the left cable and the right cable from detaching from the present invention; the left ring cover, the right ring cover, the internal thread cover and the external thread cover are sleeved on the outside of the left insulating column and the right insulating column, also forming a sealing and waterproof effect; the two half-ring clamps fix the left insulating column and the right insulating column, protect the part where the conductor rod is connected to the guide rod hole, and also form a waterproof effect; the present invention has a good waterproof effect, so water droplets will not enter the present invention, so water droplets will not interfere with the signal transmission between the cables. Therefore, the signal transmission effect of the present invention is good. BRIEF DESCRIPTION OF THE DRAWINGS

The left connecting structure 2 is provided with a left screw 23 at the center of the left fixing frame 22. The movement stroke of the left screw 23 is to rotate with the left screw 23 as the axis. The middle part of the left screw 23 is provided with a screw collar 231, and the screw collar 231 is threadedly connected to the left screw 23. The outer surface of the screw collar 231 is hinged to one end of a plurality of left connecting rods 24, and the other end of the left connecting rod 24 is hinged to the left pressure plate 241. The left pressure plate 241 is an arc columnar structure, and the center of the left pressure plate 241 coincides with the center of the left fixing frame 22. The left screw rod 23 is covered by a left column frame 25.

A plurality of frame wear plates 222 are evenly distributed on the inner surface of the left fixed frame 22, and a plurality of insulating wear plates 242 are evenly distributed on the inner surface of the left pressure plate 241.

[0065] When used, take the fixation of the left cable 4 and the left connecting structure 2 as an example, first peel off the outer shell of the left cable 4, then separate the left wire 41 in the left cable 4 one by one, then insert the left wire 41 into the left frame hole 221 one by one until the left wire 41 is connected with the wire sleeve 111, then twist the left worm 253, when the left worm 253 rotates, it drives the left worm wheel 254 to rotate, and then the middle part of the left worm wheel 254 drives the left screw 23 to rotate, and when the left screw 23 rotates, it drives the screw sleeve ring 231 The left connecting rod 24 is moved upward, and then the screw collar 231 rotates the left connecting rod 24 counterclockwise, so the left connecting rod 24 rotates the left pressure plate 241 toward the left fixing frame 22. At this time, the left pressure plate 241 presses the left wire 41 toward the left fixing frame 22, thereby achieving the effect of connecting and fixing the left wire 41 to the left fixing frame 22.

At this time, the left pressure plate 241 is away from the left fixing frame 22, so the left wire 41 is disconnected from the left fixing frame 22, and then the left wire 41 can be pulled out in sequence; the inner surface of the left pressure plate 241 is evenly distributed with a plurality of insulating wear-resistant plates 2 42. A plurality of frame wear-resistant plates 222 are evenly distributed on the inner surface of the left fixing frame 22. The insulating wear-resistant plates 242 and the frame wear-resistant plates 222 can both achieve an extrusion and fixing effect on the left wire 41, and the insulating wear-resistant plates 242 and the frame wear-resistant plates 222 can increase the friction force of the left pressure plate 241 and the inner surface of the left fixing frame 22, so the fixing effect is better; the left pressure plate 241 and the insulating wear-resistant plates 242 are both insulated, which can prevent the left wire 41 from leaking electricity, thereby improving the safety of the present invention.
