Description

Waterproof joint of waterproof motor wire outlet hole

Technical Field

The utility model relates to a cable junction spare technical field, concretely relates to waterproof motor wire hole's water joint.

Background

The traditional waterproof connector for the motor is a connecting device frequently used in an electric power system, and the waterproof connector structure for the cable is generally connected to a waterproof shell of the device. As shown in fig. 1, the tail pressing mounting body, the threading clamping rubber mat and the pressing nut are comprised. The tightening nut is screwed down to compress the front end of the threading clamping rubber mat to be in close contact with the cable jacket, so that water can be prevented from entering the joint from the cable jacket. By adopting the mode, when the cable jacket is damaged or water enters from the wire end, the inside of the cable jacket cannot be waterproof, and the problem of water inlet and electricity leakage is caused. When the nut is tightened too tightly, the contact area of the nut and the cable is small, so that the hidden trouble of breaking the cable jacket can be caused. Once the insulating sheath of the cable is damaged, water can flow into the waterproof shell along the insulating inner core, causing damage to the equipment.

Disclosure of Invention

Problem to prior art existence, the utility model provides a waterproof connection of waterproof motor wire hole.

The utility model is realized like this.

The utility model discloses a water joint of waterproof motor wire hole, including cable water joint, the cable of constituteing by cable insulation overcoat and cable metal sinle silk of drawing forth from waterproof motor wire hole, its characterized in that: cable water joint is a U type sealed cylinder, be equipped with at the lower extreme of a U type sealed cylinder with waterproof motor wire hole assorted connector card platform, it has through wires hole I to open at the bottom center of a U type sealed cylinder, the connector card platform card dress of a U type sealed cylinder is at the tip of waterproof motor wire hole to through bolt I and waterproof motor wire hole fixed connection, be equipped with end cover at U type sealed cylinder open end, it has bolt hole I to open at the open end of a U type sealed cylinder, it has bolt hole II corresponding with bolt hole I to open on sealed end cover, and will through bolt II U type sealed cylinder and end cover fixed connection, form cable water joint cavity, be equipped with high elasticity rubber buffer in cable water joint cavity, be equipped with through wires hole II at high elasticity rubber buffer, also open cable wire hole on sealed end cover, the cable pass through wires hole I of a U type sealed cylinder, The cable outlet holes on the high-elasticity rubber plug and the sealing end cover extend out of the waterproof cable joint.

The utility model has the advantages that:

the utility model discloses cable water joint adopts miniaturized processing, simple structure, and is easy and simple to handle, can be to multicore cable overcoat inside waterproof, and sealing contact area is big, and the leakproofness is good, does not have the leakage, can protect the cable moreover and prevent to install too big tension excessively bad with the cable card.

Drawings

Fig. 1 is a schematic structural view of a conventional waterproof joint.

Fig. 2 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 2, the utility model discloses a water joint of waterproof motor wire hole, including cable water joint, the cable 6 that comprises cable insulation overcoat and cable metal core that draws forth from waterproof motor wire hole, its characterized in that: the cable waterproof joint is a U-shaped sealing barrel, a connecting clamping table 10 matched with a waterproof motor wire outlet hole 1 is arranged at the lower end of the U-shaped sealing barrel, a threading hole I9 is formed in the center of the bottom of the U-shaped sealing barrel, the connecting clamping table 10 of the U-shaped sealing barrel 2 is clamped at the end part of the waterproof motor wire outlet hole 1 and fixedly connected with the waterproof motor wire outlet hole 1 through a bolt I7, a sealing end cover 3 is arranged at the open end of the U-shaped sealing barrel 2, a bolt hole I is formed at the open end of the U-shaped sealing barrel, a bolt hole II corresponding to the bolt hole I is formed in the sealing end cover 3, the U-shaped sealing barrel 2 and the sealing end cover 3 are fixedly connected through a bolt II 4 to form a cable waterproof joint cavity, a high-elasticity rubber plug 8 is arranged in the cable waterproof joint cavity, a threading hole II is formed in the high-elasticity rubber plug 8, a cable wire outlet hole 5 is, the cable passes through the threading hole I9 of the U-shaped sealing barrel, the high-elasticity rubber plug 8 and the cable outlet hole 5 on the sealing end cover and extends out of the waterproof cable joint.

The utility model discloses a high elasticity rubber buffer is whole to be filled in with the water joint cavity, has increaseed waterproof area of contact. The waterproof effect becomes more reliable, the operation is simple, and the inside of the multi-core cable jacket can be prevented from being waterproofed.

The utility model discloses an installation:

firstly, a connecting clamping table 10 of a U-shaped sealing barrel 2 is fixedly connected with a motor wire outlet, a cable passes through a threading hole I9 of the U-shaped sealing barrel 2 and a threading hole II of a high-elasticity rubber plug 8, then the high-elasticity threading rubber plug 8 is plugged into the U-shaped sealing barrel 2, as the waterproof joint is the U-shaped sealing barrel and the interior of the U-shaped sealing barrel is designed to be concave, after the high-elasticity rubber plug 8 enters the U-shaped sealing barrel 2, the cable can be tensioned in the main body due to elastic deformation, then the cable passes through a cable wire outlet 5 of an end cover, and then the sealing end cover 3 is fixedly connected with the U-shaped sealing barrel 2 through a screw. After the screw is screwed down, the high-elasticity rubber plug 8 can be compressed to completely shrink the middle cable, and the cable jacket is made of rubber, so that the cable part passing through the high-elasticity rubber plug 8 is compressed in a large area while the high-elasticity rubber plug 8 is compressed, the cable insulation jacket is tightly attached to the metal wire core of the cable, and the effect of simultaneously preventing water inside and outside the cable is achieved.
