as shown in fig. 1 and fig. 2, the utility model discloses a water blocking type intermediate head contains stifled oil type connecting pipe 1, waterproof material 2, semi-conductive sticky tape 3 and intermediate head main part 4, the both ends cover of stifled oil type connecting pipe 1 is established in the cable core 5 outside of both sides, waterproof material 2, semi-conductive sticky tape 3 set up in the clearance between the insulating layer 6 of stifled oil type connecting pipe 1 and both sides cable and semi-conductive sticky tape 3 sets up in the outside of waterproof material 2, the outside at both sides cable insulating layer 6 and stifled oil type connecting pipe 1 is established to intermediate head main part 4 covers.
Stifled oil type connecting pipe 1 is circular body, and the diameter and the cable core 5 of the hole of stifled oil type connecting pipe 1 match, is provided with the baffle in the middle of the hole of stifled oil type connecting pipe 1 and separates the hole for first blind hole and second blind hole, and the cable core 5 of one side inserts and presses fastening in the first blind hole and decide, and the cable core 5 of opposite side inserts and presses fastening in the second blind hole and decides. Separate into two independent blind holes through the intermediate hole of connecting pipe 1 with the baffle structure and connect the cable core of both sides respectively, like this with the connecting pipe 1 of the body structure of the intercommunication type of prior art, the circulation of water in the connecting pipe is worse, can effectively restrain the rivers in the cable in to connecting pipe 1.
The outer diameter of the oil plugging type connecting pipe 1 is equal to or slightly smaller than the outer diameter of the cable insulation layer 6, and the end parts of the two ends of the oil plugging type connecting pipe 1 are rounded. The cable insulation 6 ends are beveled.
The waterproof material 3 is waterproof adhesive tape. Waterproof sticky tape winds the cable core 5 outside of wrapping in the clearance between 6 tip of cable insulation layer and the 1 tip of oil-blocking type connecting pipe. In this state, the waterproof tape winds and seals the gap between the end of the cable insulation layer 6 and the end of the oil-blocking type connecting pipe 1 around the wrapping layer, and water in the cable is effectively prevented from flowing to the end face of the cable joint from the gap.
The semi-conductive sticky tape 3 winds the outside of wrapping waterproof material 2 and oil blocking type connecting pipe 1 and is even with cable insulation 6 up to the lateral surface of semi-conductive sticky tape 3. Because in the actual operation process, the external diameter of stifled oil type connecting pipe 1 can slightly be less than the external diameter of cable insulation 6 after the crimping, and semi-conductive sticky tape 3 makes the lateral surface of semi-conductive sticky tape 3 and the lateral surface parallel and level of insulating layer 6 around the package in the outside of stifled oil type connecting pipe 1 again after filling the clearance between insulating layer 6 and stifled oil type connecting pipe 1.
As shown in fig. 4, when the water-blocking type intermediate joint of the present invention is operated, the cable is first processed according to the process requirement, and the end of the cable insulation layer is chamfered. Sleeving the oil-blocking type connecting pipe, and performing connecting pipe crimping and crimping burr removal. And a waterproof material is wrapped and filled in a gap between the cable insulation layer and the oil plugging connecting pipe, and the waterproof material is slightly overlapped with the oblique angle of the cable insulation end part. And then wrapping the oblique angle of the insulating end part of the cable and the oil-blocking type connecting pipe by using a semi-conductive adhesive tape until the oblique angle is flush with the insulating layer of the cable. The middle joint main body is sleeved. And then performing subsequent cable layer-by-layer recovery operation.
Example 2:
as shown in fig. 1 and 2, the utility model discloses a water blocking type intermediate head contains stifled oil type connecting pipe 1, waterproof material 2, semiconduction sticky tape 3 and intermediate head main part 4, the both ends cover of stifled oil type connecting pipe 1 is established in the cable core 5 outside of both sides, waterproof material 2, semiconduction sticky tape 3 set up in the clearance between the insulating layer 6 of stifled oil type connecting pipe 1 and both sides cable and semiconduction sticky tape 3 sets up the outside at waterproof material 2, the outside at both sides cable insulation layer 6 and stifled oil type connecting pipe 1 is established to intermediate head main part 4 covers.
Stifled oil type connecting pipe 1 is circular body, and the diameter and the cable core 5 of the hole of stifled oil type connecting pipe 1 match, is provided with the baffle in the middle of the hole of stifled oil type connecting pipe 1 and separates the hole for first blind hole and second blind hole, and the cable core 5 of one side inserts and presses fastening in the first blind hole and decide, and the cable core 5 of opposite side inserts and presses fastening in the second blind hole and decides. The middle hole of the connecting pipe 1 is divided into two independent blind holes through the partition plate structure to be respectively connected with the cable cores on two sides, so that the water circulation in the connecting pipe is poorer than that of the connecting pipe 1 of the communication type pipe body structure in the prior art, and the water in the cable can be effectively inhibited from flowing into the connecting pipe 1.
The outer diameter of the oil plugging type connecting pipe 1 is equal to or slightly smaller than the outer diameter of the cable insulation layer 6, and the end parts of the two ends of the oil plugging type connecting pipe 1 are rounded. The cable insulation 6 ends are beveled.
