[0029] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0030] When the relay 1 is installed on the slide rail 2, the clamping device includes a fixed clamping interface 3, a fastening bolt 4 and a movable clamping interface 5. The fixed clamping interface 3 and the movable clamping interface 5 are relatively installed at the two ends of the bottom of the relay body 1. The fixed clamping interface 3 is fastened to the relay body 1, and the movable clamping interface 5 is movably connected to the relay body 1 through the fastening bolts 4 installed on the side of the relay body 1. The slide rail 2 is clamped between the fixed clamping interface 3 and the movable clamping interface 5. The fixed clamping interface 3 and the movable clamping interface 5 cooperate with each other to install the relay body 1 on the slide rail 2, and then the movable clamping interface 5 is fastened and limited by the fastening bolts 4. The installation is simple, and when the position of the relay body 1 needs to be moved, it is only necessary to loosen the fastening bolts 4, then drag the relay body 1 to slide on the slide rail 2 to the desired position, and then tighten the fastening bolts 4 to limit it, which saves time and effort and has high installation efficiency.

[0031] It also includes an installation cavity 6, which is opened at the bottom of the relay body 1. A limit block 7 is provided in the installation cavity 6, and a reset spring 8 is provided between the limit block 7 and the installation cavity 6. After the relay body 1 is installed on the slide rail 2 through the clamping device, the limit block 7 rests on the slide rail 2, and is squeezed and stressed by the limit spring to push the limit block 7 onto the slide rail 2, thereby realizing secondary limiting and avoiding the problem of the relay body 1 falling off the slide rail 2 when the electrical cabinet is shaken.

[0032] It also includes a wedge block 9, which is installed between the reset spring 8 and the limit block 7. The threaded end of the fastening bolt 4 passes through the bottom of the relay body 1 and extends into the installation cavity 6, and the end of the fastening bolt 4 extending into the installation cavity 6 rests on the inclined surface of the wedge block 9. After the clamping device is installed on the slide rail 2, the fastening bolt 4 is tightened, and the threaded end of the fastening bolt 4 presses the wedge block 9 downward through the inclined surface of the wedge block 9, driving the limit block 7 to be tightly attached to the slide rail 2 to ensure effective limiting.

[0033] The slide rail 2 is provided with a mounting hole 10 , and the fasteners are used to detachably mount the slide rail 2 in the electrical cabinet through the mounting hole 10 , which is convenient for disassembly and access.

[0034] The movable card interface 5 is slidably installed with the bottom of the relay body 1 through a sliding component, and the sliding component is used to limit the movable card interface 5 to prevent the movable card interface 5 from being skewed during the tightening process of the fastening bolt 4.

[0035] The sliding assembly includes a sliding groove 11 and a slider 12. The slider 12 is arranged at the bottom of the relay body 1. The sliding grooves 11 are provided on both sides of the slider 12. The sliding boss 13 is located on both sides of the groove of the movable card interface 5. The sliding boss 13 is slidably installed in the sliding groove 11.

[0036] A stop plate 14 is provided at the end of the slide rail 2 to prevent the relay body 1 from slipping off during the sliding process on the slide rail 2 through the clamping device.

[0037] A gap is provided between the fixed card interface 3 and the movable card interface 5 and the relay body 1 , and the height of the gap matches the thickness of the rail edge of the slide rail 2 .

[0038] Rubber gaskets 15 are respectively installed on the opposite ends of the fixed card interface 3 and the movable card interface 5. When the width of the slide rail 2 is small, the opposite ends of the fixed card interface 3 and the movable card interface 5 are tightened and contacted, thereby increasing the friction between the fixed card interface 3 and the movable card interface 5.

[0039] When using:

[0040] After the relay body 1 is installed on the slide rail 2, loosen the fastening bolt 4 and pull the movable card interface 5 outward to make room for the installation distance, so that the fixed card interface 3 can be easily connected to the edge of the slide rail 2. Then tighten the fastening bolt 4 so that the movable card interface 5 is also connected to the edge of the slide rail 2. At this time, the threaded end of the fastening bolt 4 squeezes the wedge block 9 downward through the inclined surface of the wedge block 9, driving the limit block 7 to fit tightly against the slide rail 2. Relying on the fixed card interface 3 and the movable card interface 5 for secondary limiting, the stability of the installation of the relay body 1 is ensured.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
