[0002] The most common way to transfer power, transport, and transmit signals is through cables. At the starting point, end point, or even some intermediate points of power and signal transmission, it is often necessary to transfer to the cable through equipment. Generally speaking, cables and devices are connected through terminal blocks.

[0003] When using existing multi-interface connection terminals, the cables are usually crimped onto the terminal blocks by bolts and pressing plates. However, the existing multi-interface connection terminals are unable to clamp and fix the cables, which causes the cables to easily fall off when pulled by external forces, thereby causing the circuit to be disconnected. Moreover, when multiple groups of cables are connected to the terminal blocks at the same time, the cables are easily mixed and intertwined, thereby affecting the subsequent maintenance work and making it difficult to meet the usage requirements.

[0022] In this embodiment, through the elasticity of the spring 11, the movable rod 7 can be driven to slide on the fixed frame 6, thereby prompting the U-shaped insulating buckle 10 to be inserted into the slot group 5, so that the cable clamp crimped on the terminal body 2 can be fixed to the side of the base 1, and at the same time, by pulling the pull ring 9, the spring 11 can be squeezed to contract, and the U-shaped insulating buckle 10 can be pulled out of the slot group 5, so as to effectively fix the cable crimped on the terminal body 2, prevent the cable from falling off due to external force, and improve the stability during use. At the same time, multiple or multiple groups of cables connected to the terminal body 2 are combed to prevent the cables from being mixed and intertwined, which facilitates the normal progress of subsequent maintenance work and meets actual use needs.

[0023] Example 2: Figure 1-Figure 4 As shown, a protective cover plate 12 is provided on the top of the partition, and two groups of mounting bolts 17 are symmetrically provided at both ends of the top of the protective cover plate 12. One end of the mounting bolt 17 movably passes through the protective cover plate 12 and is connected to the partition. Four groups of bracket groups 13 are symmetrically provided at both ends of the protective cover plate 12. A fixed shaft 14 is fixedly connected to the inner side of the bracket group 13, and a protective buckle 15 is rotatably connected to the outer side of the fixed shaft 14. The protective buckle 15 is arranged in the connection area. A card slot 16 is penetrated through the top of the protective cover plate 12, and the size of the card slot 16 corresponds to the fixed block 3. Pressing sheets 18 are provided at both ends of the top of the terminal body 2. A fixing bolt 19 is provided on the top of the pressing sheet 18.

Mounting seats 21 are symmetrically provided on both sides of the base 1, and a countersunk screw hole 22 is penetrated through the top of the mounting seat 21.

[0024] In this embodiment, the protective cover 12 is fixed to the partition by installing bolts 17. The protective cover 12 can prevent dust or water vapor from damaging the terminal body 2 and the cable. At the same time, by toggling the protective buckle 15, it can be rotated on the fixed shaft 14 and then inserted into the connection area to limit the cable crimped on the terminal body 2 and prevent dust from accumulating in the connection area, thereby improving the protection performance of the device, extending its service life, and maintaining stable line connection. By inserting the fixing block 3 into the card slot 16, the protective cover 12 can be further fixed to prevent the protective cover 12 from falling off. By twisting the fixing bolt 19 and pushing the pressing piece 18 downward, the cable can be crimped onto the terminal body 2.

At this time, release the pull ring 9, make the spring 11 rebound, push the U-shaped insulating buckle 10 into the slot group 5, clamp the cable, repeat the above steps, connect all the cables to be connected to the terminal body 2, then turn the installation bolt 17, install and fix the protective cover 12, and finally, move multiple protective buckles 15 in turn to make them rotate on the fixed shaft 14, and insert them into the connection area to limit the cable, thereby completing the use of the terminal with multiple interfaces.
