The cable joint protection device is used for protecting joint parts of two cables and comprises a first hard shell, a second hard shell and two welding sections, wherein the first hard shell is used for sleeving one cable; the second hard shell is used for being sleeved on another cable, and the second hard shell is connected with the first hard shell in a sealing mode to form an accommodating space for accommodating the joint part of the cable; the two welding sections are respectively connected to the ends, deviating from each other, of the first hard shell and the second hard shell, and the welding sections can be in welding connection with the outer sheath of the cable. The cable joint protection device is simple in structure, has the capability of resisting external extrusion and is good in waterproof effect.)

1. A cable splice protector for protecting splice sites of two cables, comprising:

a first hard shell (1) for sheathing one of the cables;

the second hard shell (2) is sleeved on another cable, and the second hard shell (2) is connected with the first hard shell (1) in a sealing mode to form a containing space for containing a joint part of the cable;

the two welding sections (3) are respectively connected to one ends, deviating from each other, of the first hard shell (1) and the second hard shell (2), and the welding sections (3) can be in welding connection with the outer sheath of the cable.

2. The cable joint protector according to claim 1, characterized in that one of the first hard shell (1) and the second hard shell (2) is provided with an annular boss (4) on the end surface, and the other end surface is provided with a plug groove (5) along the circumferential direction, and the annular boss (4) is plugged into the plug groove (5).

3. The cable joint protector according to claim 2, characterized in that the circumferential surface of the annular boss (4) is provided with an annular groove (6), the annular groove (6) and the wall of the insertion groove (5) enclose an annular accommodating cavity, and the annular accommodating cavity is filled with waterproof glue.

4. A cable splice guard as claimed in claim 3, characterized in that the wall of the plug groove (5) is provided with glue injection holes (7), said glue injection holes (7) communicating with the annular groove (6).

5. A cable splice guard as claimed in claim 4, characterized in that the cable splice guard further comprises a connecting peg (9), the connecting peg (9) being capable of plugging the glue hole (7).

6. The cable splice guard according to claim 5, wherein the circumferential surface of the annular boss (4) is provided with a positioning hole (8) corresponding to the position of the glue injection hole (7), and the connecting bolt (9) can be inserted into the positioning hole (8) through the glue injection hole (7).

7. The cable joint protector according to claim 6, characterized in that the number of the glue injection holes (7) and the number of the positioning holes (8) are equal and multiple, and the glue injection holes (7) are uniformly distributed along the circumferential direction of the wall of the insertion groove (5).

8. A cable splice protection device according to any one of claims 1 to 7, characterized in that said fused section (3) is a shell of revolution, the cross-sectional area of the end of said fused section (3) connecting said first rigid shell (1) and said second rigid shell (2) being greater than the cross-sectional area of the other end.

9. A cable splice protection device according to any one of claims 1 to 7, characterised in that said fusion splicing section (3) is made of ethylene propylene diene monomer; and/or the first hard shell (1) and the second hard shell (2) are made of polyethylene.

10. A cable splice protection device according to any one of claims 1 to 7, characterized in that two of said fused sections (3) are fused to said first rigid shell (1) and said second rigid shell (2), respectively.
