Detailed Description
The following further description of embodiments of the invention is made with reference to the accompanying drawings:
as shown in figure 1, the cable joint sealing structure comprises a body 5, a nut 1, a clamping claw 2, a clamping head 6, a clamping ring 7 and a cable plug 8, wherein the outer surface of the left end of the body 5 is in threaded connection with the nut 1, the outer surface of the right end of the body 5 is in threaded connection with the left end of the clamping head 6, the middle of the body 5 is provided with a circle of outer hexagon of the body, a body O-shaped ring groove is formed in the outer hexagon of the body and faces one side face of the nut 1, a body O-shaped sealing ring 4 is arranged in the body O-shaped ring groove, the left end of the clamping claw 2 is inserted into the body 5, the clamping claw 2 is in sealed connection with the body 5 through the clamping claw O-shaped sealing ring 3, the right end of the clamping claw 2 is positioned outside the body 5 and inside the clamping head 6, the inner side of one end (namely the right end of the clamping claw 2) of the clamping claw 2 positioned outside the body 5, one end of the cable plug 8 is plugged into the through hole at the right end of the packing head 6 and is positioned at the inner side of the packing ring 7.
In this embodiment, as shown in fig. 2, an electric cabinet shell 10 is installed between the nut 1 and the outer hexagon of the body.
In this embodiment, as shown in fig. 1, a clamping claw O-ring groove is formed in an outer surface of one end of the clamping claw 2, and a clamping claw O-ring 3 is placed in the clamping claw O-ring groove.
In this embodiment, as shown in fig. 1, one end of the clamping claw 2 (i.e. the right end of the clamping claw 2) provided with the clamping ring 7 is provided with a circle of gap 9 extending along the length direction thereof, so that the clamping head 6 can compress the clamping claw 2, thereby clamping the cable through the clamping ring 7.
In this embodiment, the inner diameter of one end (i.e. the left end of the packing head 6) of the packing head 6 connected with the body 5 is larger than the inner diameter of the other end (i.e. the right end of the packing head 6).
In this embodiment, the clamping claw 2 is made of plastic.
In this embodiment, body O type sealing washer 4, step up claw O type sealing washer 3, compel tight circle 7 and cable stopper 8 all adopt rubber material.
In this embodiment, the nut 1, the body 5 and the packing head 6 are all made of stainless steel.
The installation process of this embodiment is:
internal sealing: when installing the cable, the cable plug 8 needs to be removed and a cable with a predetermined diameter is installed. The tightening head 6 rotates rightwards to compress the tightening claw 2, the tightening claw 2 contracts inwards to press the tightening ring 7, and external gas or liquid cannot enter the electric cabinet from the outer diameter of the cable. The clamping claw O-shaped ring 3 is mainly used for sealing between the clamping claw 2 and the body 5. Eliminating the problem of sealing inside the body 5.
External sealing: as shown in fig. 2, the conventional stainless steel joint does not have the main body O-ring 4 and the main body O-ring groove. Basically, the nut 1 and the body 5 are sealed by a flat gasket, but when the nut and the body are connected through the electric cabinet shell 10, the phenomenon of poor sealing of the flat gasket can be generated. In this embodiment, after the body O-ring groove and the body O-ring 4 are added, no leakage occurs between the body 5 and the electric cabinet case 10.
Fig. 1 shows that the sealing effect of the stainless steel joint can meet the requirement of IP68 from the perspective of the stainless steel joint. Fig. 2 shows that from the whole system, only the inner seal can not meet the requirement, and only the inner seal and the outer seal can all meet the requirement of IP68, so that the system can meet the requirement of IP 68.
This embodiment increases waterproof performance through body O type ring groove. And a body O-shaped sealing ring 4 is arranged in the body O-shaped ring groove. The groove depth of the O-shaped seal ring groove of the body is 2/3 the diameter of the O-shaped seal ring 4 of the body, and the nut 1 is screwed down, so that the electric cabinet shell 10 is in close contact with the O-shaped seal ring 4 of the body, and the external sealing performance is achieved. To sum up, this embodiment simple structure, convenient operation, installation maintenance is convenient. The market types and the models of the selected products are complete, and the relative products can be reasonably selected according to the use condition. The waterproof grade is improved, and the waterproof effect is greatly improved under the same condition.
The protection scope of the present invention includes but is not limited to the above embodiments, the protection scope of the present invention is subject to the claims, and any replacement, deformation, and improvement that can be easily conceived by those skilled in the art made by the present technology all fall into the protection scope of the present invention.
