[0035] Reference Figure 3 and Figure 4 The fixing assembly 7 includes a moving plate 71, and the fixing assembly 7 is provided with four groups, corresponding to four groups of relays 5 at different positions. A slide groove is provided on the top of the moving plate 71, and the slide groove is symmetrically distributed in two groups. The slide groove guides the clamping plate 72 to prevent the clamping plate 72 from deflecting when moving. The inner wall of the slide groove is slidably connected with a clamping plate 72, and the clamping plate 72 is symmetrically distributed in two groups. The clamping surface of the clamping plate 72 is made of rubber material. The right side of the clamping plate 72 is fixedly connected with a cylindrical block 75, and the cylindrical block 75 is symmetrically distributed in two groups. Through the fixing effect of the cylindrical block 75, the cylindrical block 75 is prevented from deflecting. To prevent the movable plate 71 from shifting during movement, a circular hole 710 is provided on the top of the mounting plate 4. The bottom end of the inner wall of the circular hole 710 is elastically connected to the bottom left end of the movable plate 71 through a spring 73. Through the elastic force of the spring 73, the movable plate 71 always keeps sliding upward along the inner wall of the guide groove without being affected by external force.

[0036] Reference Figure 1and Figure 6 The snap-fit ​​assembly 8 includes snap hooks 81, and there are two groups of snap hooks 81 symmetrically distributed. The left inner wall of the bottom plate 1 is elastically connected with a wedge block 83 through a reset spring 82. Through the elastic force of the reset spring 82, the wedge block 83 always maintains the snap-fit ​​effect with the snap hook 81 when not affected by external force, thereby limiting the cover plate 2.

[0037] Reference Figure 4 and Figure 5 A groove 77 is provided on the top of the mounting plate 4, and the inner wall of the groove 77 is elastically connected to the limiting block 78 through a limiting spring 79. Through the elastic force of the limiting spring 79, the limiting block 78 always remains engaged with the top of the moving plate 71 without being affected by external force, thereby limiting the moving plate 71. One end of the spring 73 is fixedly connected to the bottom end of the inner wall of the circular hole 710, and the other end of the spring 73 is fixedly connected to the bottom left end of the moving plate 71. The fixing effect of the spring 73 prevents the spring 73 from falling off.

[0038] Reference Figure 3 and Figure 4 The top of the movable plate 71 contacts the bottom of the relay 5, and the bottom pin of the relay 5 can pass through the top opening of the movable plate 71, so that the bottom of the relay 5 can contact the top of the movable plate 71, and the right side of the movable plate 71 is slidably connected to the inner wall of the guide groove. Through the sliding effect of the movable plate 71, the movable plate 71 can lift the relay 5 upward, and the cylindrical block 75 is slidably connected to the inner wall of the inclined groove 76. Through the sliding effect of the cylindrical block 75, the clamping plate 72 slides along the inner wall of the slide groove. The bottom end of the inner wall of the circular hole 710 is fixedly connected with a telescopic rod 74. The telescopic rod 74 improves the stability of the movable plate 71 during movement, and the top of the telescopic rod 74 is fixedly connected to the bottom left end of the movable plate 71.

[0039] Reference Figure 1 and Figure 6 The top of the buckle 81 is fixedly connected to the bottom of the cover plate 2, and the fixing effect of the buckle 81 prevents the buckle 81 from falling off. The inner wall of the cover plate 2 is plugged into the outer periphery of the frame 3. One end of the return spring 82 is fixedly connected to the left inner wall of the bottom plate 1, and the other end of the return spring 82 is fixedly connected to the right side of the wedge block 83. The fixing effect of the return spring 82 keeps the wedge block 83 fixed to prevent the wedge block 83 from falling off. The outer wall of the wedge block 83 is slidably connected to the left inner wall of the bottom plate 1. The sliding effect of the wedge block 83 makes the wedge block 83 and the buckle 81 be engaged or released. The outer wall of the wedge block 83 is engaged with the inner wall of the buckle 81. The engaging effect of the wedge block 83 and the buckle 81 makes the bottom plate 1 limit the cover plate 2.

[0040] Reference Figure 5The locking cam 77 is pressed against the locking cam 78 to lock the locking cam 76. The locking cam 76 is pressed against the support cam 76 and the support cam 76 is engaged with the stop cam 76. The stop cam 76 is pressed against the support cam 76 to lock the locking cam 76.

[0041] Working principle: When the staff needs to install the electrical components in the vehicle fuse box, the staff presses the wedge block 83 to release the clamping effect of the wedge block 83 on the buckle 81, and at the same time releases the limiting effect on the cover plate 2, so that the staff can remove the cover plate 2, and then plug the pins of the fuse 6 into the mounting plate 4, and move the pins of the relay 5 downward through the top opening of the movable plate 71, so that the movable plate 71 slides downward along the inner wall of the guide groove to squeeze the spring 73, and at the same time drives the cylindrical block 75 to slide along the inner wall of the inclined groove 76, so that the clamping plate 72 slides along the inner wall of the slide groove toward the relay 5 until the pins of the relay 5 are plugged into the mounting plate 4, and at the same time, the two sets of clamping plates 72 can clamp and fix the relay 5.

[0042] When the bottom of the movable plate 71 contacts the top of the mounting plate 4, the limit block 78 is clamped with the top of the movable plate 71 through the elastic force of the limit spring 79, so that the movable plate 71 remains fixed, and at the same time, the two sets of clamping plates 72 are always kept in a fixed clamping state, thereby performing a secondary fixation on the relay 5. Subsequently, the staff plugs the cover plate 2 and the frame 3 together, so that the wedge block 83 is clamped with the buckle 81 under the elastic force of the reset spring 82, and at the same time, the cover plate 2 is limited, so that the cover plate 2 remains fixedly installed on the base plate 1, thereby protecting the electrical components in the frame 3.

[0043] When the relay 5 in the frame 3 needs to be maintained, the staff removes the cover plate 2 and pushes the limit block 78 outward so that the limit block 78 releases the clamping effect on the movable plate 71, thereby releasing the limiting effect on the movable plate 71. At the same time, the elastic force of the spring 73 drives the movable plate 71 to move upward, so that the movable plate 71 drives the relay 5 to move upward, releasing the plug-in effect with the mounting plate 4. At the same time, the clamping plate 72 is driven by the cylindrical block 75 to slide in the direction away from the relay 5, thereby releasing the clamping and fixing effect on the relay 5, thereby facilitating the staff to disassemble and maintain the relay 5.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
