[0028] Example:

[0029] like Figures 1-5 As shown, an embodiment of the present invention provides an integrated new type of cable terminal adapter clamp, including a base plate 1, a boss 2, a cable entry hole 3, a locking bolt hole 4, a mounting hole 5, a mounting groove 6 and a torque bolt 7. A boss 2 is integrally formed in the center of the upper surface of the base plate 1, and a plurality of cable entry holes 3 are opened on the side of the boss 2. A plurality of locking bolt holes 4 are opened above the boss 2, and the bottom of the locking bolt hole 4 passes through the cable entry hole 3. A through groove 301 is opened between two adjacent cable entry holes 3. Mounting holes 5 are opened on both sides of the upper surface of the base plate 1, and mounting grooves 6 are opened on both sides of the upper surface of the base plate 1. The locking bolt hole 4 is threadedly connected to a torque bolt 7.

[0030] The torque bolt 7 comprises a dismounting hex head 701, a breaking part 702, a tightening hex head 703 and a thread groove 704, the bottom of the torque bolt 7 is fixedly provided with the dismounting hex head 701, the top of the dismounting hex head 701 is fixedly provided with the breaking part 702, the top of the breaking part 702 is fixedly provided with the tightening hex head 703, and the bottom of the torque bolt 7 is provided with the thread groove 704.

[0031] The utility model discloses a plurality of cable through holes 3 are set up, so that one wire clamp can complete the switching demand of cable terminal, and the structure is more compact, and the operation is more convenient.

[0032] Through being provided with the through groove 301, the ventilation of the cable through hole 3 is increased, so that the heat of the cable and the cable through hole 3 contact place is dissipated from the through groove 301, prevents cable overheating and fuses, prevents the occurrence of power failure.

[0033] In the embodiment, the bottom plate 1 and the boss 2 are made of aviation aluminum alloy material.

[0034] The aviation aluminum alloy material is corrosion-resistant, has small surface contact resistance, low operating temperature rise under rated current conditions, less power loss and significant energy-saving effect.

[0035] In the embodiment, the number of the corresponding locking bolt holes 4 on each cable through hole 3 is not less than 2.

[0036] The cable is fastened in the cable through hole 3 by the plurality of torque bolts 7, the stability of the cable fixed in the cable through hole 3 is increased, and the cable is prevented from loosening.

[0037] In the embodiment, the breaking part 702 is in the shape of a cylinder with large diameter at both ends and small diameter in the middle, facilitating the breaking of the breaking part.

[0038] By setting the torque bolt, only a socket wrench matched with the tightening hex head 703 is needed to complete installation without professional installation skills; the breaking part on the safety value torque bolt is automatically disconnected, thereby ensuring the uniformity of construction, solidifying the installation torque, making acceptance convenient, safe and reliable, and improving work efficiency.

[0039] In the embodiment, the height of the through groove 301 is 0.2-0.5 times the cable through hole, and the height of the through groove is smaller than the size of the cable, preventing the cable from entering the through groove 301.
