They are often connected to sensors through a one-to-four cable for real-time monitoring. The one-to-four cable protects the connection parts of the main cable and the branch cable through a simple card-mounted connector.

[0004] However, the traditional one-to-four cable connector is simply snapped together and can be easily damaged and separated when dropped or subjected to external collisions, thus losing its protective function for the cables and lacking stability. Utility Model Content

When the surface of the hemispherical block moves to the bottom surface of the guide rod hole, the surface of the second connecting head contacts the surface of the first connecting head at the same time. At this time, the hemispherical block is not in contact with the surface of the limit block. Due to the elasticity of the spring, the spring reset will push the baffle to move, so that the lower surface of the limit block contacts the plane surface of the hemispherical block.

[0029] A guide rod 11 is fixed on the surface of the second connecting head 3, a hemispherical block 12 is fixed on the end surface of the guide rod 11, a limit block 7 is provided on the surface of the hemispherical block 12, and the surface where the hemispherical block 12 contacts the limit block 7 has a certain slope, so the movement of the hemispherical block 12 will squeeze the limit block 7, so that the limit block 7 is stored in the storage groove 8, and a baffle 13 is fixed on the end of the limit block 7.

[0030] Embodiment 2

[0031] On the basis of the first embodiment, in order to achieve the stability of the connector clamping, the first connector 2 and the second connector 3 are provided with a main cable 1 on one end surface, the first connector 2 and the second connector 3 are provided with an output terminal 4 on the other end surface, and the first connector 2 and the second connector 3 on the other side of the main cable 1 are provided with an input terminal 5;

[0032] The main cable 1 has an outer cover 14 on its outer surface, a braid 15 on its inner curved surface, an aluminum foil 16 on its inner curved surface, a core wire 17 on its inner curved surface, and a group of white ground wires 18 inserted into the main cable 1.

[0033] There are multiple groups of hemispherical blocks 12, which are symmetrically distributed on the surface of the second connector 3. There are multiple groups of guide rod holes 6, which are symmetrically distributed on the surface of the first connector 2. The hemispherical blocks 12 correspond to the guide rod holes 6, and the hemispherical blocks 12 are clamped in the guide rod holes 6, and the two are movably connected.

[0034] There are multiple groups of baffles 13, which are symmetrically distributed inside the first connector 2. There are multiple groups of receiving grooves 8, which are symmetrically distributed on the arc surface of the guide rod hole 6. The baffles 13 correspond to the receiving grooves 8. The baffles 13 are clamped in the receiving grooves 8. The two are movably connected. The movement of the hemispherical block 12 will squeeze the limit block 7, so that the limit block 7 is stored in the receiving groove 8.

[0035] The size of the baffle 13 is the same as that of the storage slot 8, the size of the storage slot 8 is larger than the size of the slot 10, the size of the slot 10 is larger than the size of the limit block 7, and the baffle 13 is clamped in the storage slot 8, so the baffle 13 will not be separated from the storage slot 8, and the limit block 7 will not be separated from the storage slot 8;
