The inner wall of the insulating sheath is connected with the outer wall of the copper rod. The clamping groove is located at the lower end of the inner wall of the plug tube, and the circular The clamping plate is connected and fixed, the insulating cork is fixedly connected to the lower end surface of the pressing plate, the threading hole is located on the central axis of the pressing plate and the insulating cork, the slope of the cork and the cork tube Inner tube hole fit, compression connection.

Preferably, the connection between the plug tube and the copper rod is a transition connection.

Preferably, the depth of the contact hole does not exceed the edge distance of the middle locking groove.

Beneficial effect:

The device of the utility model has a simple structure, is easy to operate, can quickly connect the wire cores, saves the cumbersome process of installation, and the soft contact makes the whole device have good airtightness and waterproof ability after the wires are connected.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, further clarifies the utility model, and this embodiment implements under the premise of the technical solution of the utility model, and it should be understood that these examples are only used to illustrate the utility model and are not intended to limit the utility model range.

As shown in Figures 1 to 5, a disconnection connection device includes a conductor, a protective layer and a fastening device, and a copper rod 11, a contact hole 12, a circular clamp 13 and an intermediate clamp are arranged on the conductor Groove 14; an insulating leather sheath 21 and an intermediate boss 22 are provided on the protective layer; a plug tube 31, a card slot 32, a pressing plate 33, an insulating cork 34, Threading hole 35.

The contact hole 12 is located at the center of both ends of the copper rod 11, the bottom of the hole is not open, the contact hole 12 is used to place the inner core of the wire, the copper rod 11 acts as an indirect conductor, and transmits the current of the line. The two ends of the outer wall at both ends of the rod 11 are fixedly connected with the copper rod 11, and the material is the same as that of the copper rod 11. The diameter of the outer ring is 1.5 times the outer diameter of the copper rod 11, and the wider convex edge can have a better fixing effect , the middle card slot 14 is located in the middle of the outer wall of the copper pipe, the upper and lower width of the middle card slot 14 cannot exceed the solid length in the middle of the copper rod 11, so as to ensure that the upper and lower wall thicknesses will not be too thin, which will affect the strength, and the middle boss 22 is located in the insulating leather sheath The middle position of the inner wall of 21 is connected with the middle card slot 14 to fix the insulating sheath 21. The inner wall of the insulating sheath 21 is connected with the outer wall of the copper rod 11. In order to ensure the sealing, the insulating sheath 21 adopts the way of encapsulation , firmly fixed on the outer wall of the copper rod 11.

The clamp groove 32 is located at the lower end of the inner wall of the plug tube 31, and cooperates with the circular clamp 13 to connect and fix the plug tube 31 to the two ends of the copper rod 11 so that it will not loosen and fall off. After the connection, the insulating leather sheath 21 packs When gluing, seal the gap between the lower end of the plug tube 31 and the copper rod together to ensure that water or other liquids can slowly seep in. The insulating soft plug 34 is fixedly connected to the lower end surface of the pressing plate 33, and the pressing plate 33 is made of hard It needs to ensure that it will not be deformed due to force. The insulating cork 34 has the ability to compress radially. After being deformed, the hole of the threading hole can be squeezed and deformed inward. The threading hole 35 is located on the pressing plate 33 and the insulating cork 34. On the central axis, the inclined plane of the insulating soft plug 34 is matched with the inner tube hole of the plug tube 31, and is compressed and connected. In order to ensure that the device has good sealing performance, the plug tube 31 and the pressing plate 33 are made of hard insulating material.

During use, the insulation layer at the broken wire end is peeled off for one end distance, and the electric wire is passed through the upper end of the threading hole 35, and the wire core passes through the threading hole 35 completely, and touches the bottom end of the contact hole 12, and the insulating soft plug 34 is pressed into the plug tube On the upper end of 31, the insulating soft plug 34 is deformed and squeezed inward, and the threading hole 35 will reduce the hole diameter, compact and fix the wire tightly, and have good sealing performance. The same operation at both ends can quickly connect the broken wire Good, and waterproof and dustproof.
