In order to achieve the purpose, the utility model adopts the technical scheme that: a high-sealing plug on a cable junction box comprises an upper plug block, a rubber pressing block, a lower plug block, an extrusion screw, a binding post and a locking nut;
the upper plugging block is provided with an upper wire passing hole for a cable to pass through and an upper positioning hole for a binding post to pass through, and the extrusion screw is inserted and sleeved in the upper positioning hole and is in threaded connection with a screw hole on the upper end surface of the binding post;
the lower end face of the rubber pressing block is in contact and butt joint with the lower plugging block, the upper end face of the rubber pressing block is provided with a trapezoidal pressing block, the trapezoidal pressing block is provided with an extrusion hole which penetrates through the rubber pressing block and is opposite to the upper wire passing hole in position, the inner bottom face of the upper plugging block is provided with a trapezoidal pressing cavity, and the trapezoidal pressing cavity is sleeved on the outer peripheral face of the trapezoidal pressing block and extrudes the trapezoidal pressing block in use; the rubber pressing block is provided with a through hole opposite to the upper positioning hole;
the lower plugging block is provided with a lower wire passing hole and a locking hole, the lower wire passing hole is used for allowing a cable to pass through, and the locking hole is used for positioning a binding post and locking the binding post through a locking nut;
the wiring terminal is used for connecting the upper plugging block, the rubber pressing block and the lower plugging block, the upper end of the wiring terminal is positioned in the upper plugging block, and the lower end of the wiring terminal penetrates through the lower plugging block.
The extrusion hole is of a trapezoidal structure with a wide upper part and a narrow lower part.
The through hole is of a square hole structure, and the part, matched with the through hole, on the binding post is of a square structure.
After adopting the structure, compared with the prior art, the utility model has the advantages that: when the upper plugging block is used, the trapezoidal pressing cavity at the bottom of the upper plugging block extrudes the trapezoidal pressing block to shrink the aperture of the trapezoidal pressing block, so that the sealing effect is achieved.

Detailed Description
The following description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention, and the present invention is further described with reference to the accompanying drawings and embodiments.
Examples, see fig. 1-4: the utility model provides a high sealed end cap on cable terminal box, its includes sprue 10, rubber briquetting 11, lower sprue 12, extrusion screw 13, terminal 14 and lock nut 15, sprue 10, rubber briquetting 11 and lower sprue 12 are made for the rubber material, terminal 14 is used for connecting sprue 10, rubber briquetting 11 and lower sprue 12, and its upper end is fixed a position in last sprue 10, and its lower extreme runs through lower sprue 12, and this kind of split type connection structure can let easy to assemble and replacement. The upper plugging block 10 is provided with an upper wire passing hole 16 for a cable to pass through and an upper positioning hole 17 for a wiring terminal 14 to pass through, the aperture of the upper wire passing hole 16 is generally smaller than the outer diameter of the cable, and the upper wire passing hole is elastically expanded to be in interference insertion with the cable; the extrusion screw 13 is inserted and sleeved in the upper positioning hole 17 and is in threaded connection with a screw hole on the upper end face of the binding post 14, and when the extrusion screw 13 is rotated in use, a nut on the extrusion screw applies force to a step in the upper positioning hole 17 so as to drive the upper plugging block 10 to move downwards for extrusion. The lower terminal surface of rubber briquetting 11 contacts butt with lower sprue 12, its up end has trapezoidal briquetting 18, trapezoidal briquetting 18 is gone up to have and runs through rubber briquetting 11 and with last line hole 16 relative extrusion hole 19 in position, extrusion hole 19 is the narrow trapezium structure about wide, last sprue 12's interior bottom surface has trapezoidal pressure chamber 20, trapezoidal pressure chamber 20 is established at the outer peripheral face of trapezoidal briquetting 18 and is pushed it in last sprue 10 moves down to let it reduce the internal diameter, reach sealed effect.
