The utility model has the advantages of it is following: the problem that the most simple structure of ordinary power cable among the prior art has been solved through grease proofing corrosion resistant rubber ring and separation rubber ring, can't adapt to special service environment, and grease proofing problem of non-corrosion has solved current special power cable through the electrically conductive casing of slot and has mostly worked a telephone switchboard for cutting open the line, the efficiency is influenced to waste time and energy.
The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1-4, a corrosion-resistant and oil-resistant special power cable includes: socket 1, socket 1 inner wall center bonding is connected with insulation board 3, three slot 4 has evenly been seted up to 3 outer wall one sides of insulation board, the card of the 4 inner walls of slot is equipped with conductive housing 5, the inner wall sliding connection of conductive housing 5 has contact point 6, conductive housing 5 keeps away from contact point 6 one side sliding connection has contact point 7 No. two, contact point 6 is equipped with spring 8 with No. two contact point 7 inner walls, socket 1 inner wall is pegged graft and is had cable conductor 9, cable conductor 9 is inside to be equipped with three wires 16, socket 1 one end welded connection has lotus flower tail 11, 11 outer wall threaded connection of lotus flower tail has lock sleeve 12, seal groove 13 has been seted up to lock sleeve 12 inner wall, lock sleeve 12 keeps away from 1 one end welded connection of socket and prevents expand tube 15, 3 both sides inner structure of insulation board is the same.
The diameter of the outer ring of the conductive shell 5 is larger than the diameter of the inner wall of the slot 4, the conductive shell is used for being more stably fixed on the inner wall of the insulating plate 3, the slot 4 is annularly and uniformly distributed on the outer wall of the insulating plate 3 and is used for adapting to the installation of an annularly distributed cable, the outer wall of the lotus tail 11, which is close to one end of the inserting seat 1, is sleeved with an oil-proof and corrosion-resistant rubber ring 10, the inner wall of the sealing groove 13 is provided with a blocking rubber ring 14 for playing a role in preventing corrosion and oil, the diameter of the inner wall of the inserting seat 1 is the same as that of the outer wall of the cable 9 and is used for tightly inserting, both ends of the outer wall of the inserting seat 1 are welded with the pointing blocks 2 for convenient recognition, the diameter of the outer wall of the cable 16 is the same as that of the inner wall of the slot 4 and is used for tightly inserting the cable 16, the inner wall of the locking sleeve 12 is inclined, and is used for providing a compression force when being screwed, one end of the lotus tail 11 is uniformly provided with a groove and is fixed with the inner wall of the cable 9, further increasing the sealing effect.
Specifically, when the cable connector is used, the locking sleeve 12 is sleeved on the outer wall of the cable 9, then the cable 9 is inserted into the socket 1 after the position is identified by the pointing block 2, at the moment, three wires 16 arranged in the cable 9 are inserted into the three slots 4 on one side of the insulating plate 3, the exposed parts of the three wires 16 are contacted with the first contact point 6 and are continuously inserted inwards, and after the cable is completely inserted, the locking sleeve 12 is gradually screwed on the outer wall of the socket 1, the inclined screw thread arranged on the inner wall of the locking sleeve 12 gradually extrudes the lotus tail 11 in the screwing process, so that the lotus tail 11 gradually clamps the outer wall of the cable 9, the problem that the efficiency is influenced by time and labor consumption because most of the existing special power cables are connected by cutting wires is solved, and grease proofing corrosion resistant rubber ring 10 and separation rubber ring 14 have solved the most simple structure of ordinary power cable among the prior art, can't adapt to special service environment, the grease proofing problem of corrosion resistant.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
Other parts not described in detail in the present invention belong to the prior art, and are not described herein again.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
