[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0030] Reference Figure 1-Figure 10 , an electromagnetic interference-proof graphics card connecting cable, comprising a connecting cable 1 and wiring heads 2 arranged at both ends, and also comprising: a first rubber sleeve 3, fixedly connected to the right end of the wiring head 2; a first spring 4, fixedly connected in the first rubber sleeve 3; a fixing plate 5, fixedly connected to the first spring 4; a second spring 6, fixedly connected in the first rubber sleeve 3; a connecting block 7, fixedly connected to the second spring 6; a clamping rod 8, rotatably connected in the first rubber sleeve 3; an L-shaped reset plate 9, slidably connected in the first rubber sleeve 3; a protective sleeve 10, slidably connected in the first rubber sleeve 3, a surface of the protective sleeve 10 is fixedly connected to a limiting rod 11, and a surface of the limiting rod 11 is provided with a clamping groove matching the clamping rod 8, when it is necessary to When protecting the terminal head 2, the limiting rod 11 is driven by the protective sleeve 10 to enter the first rubber sleeve 3, and the limiting rod 11 contacts the clamping rod 8. The clamping rod 8 shakes under the action of the second spring 6, so that the limiting rod 11 slides over the clamping rod 8 and contacts with the clamping groove of the limiting rod 11, so that the clamping rod 8 enters the clamping groove of the limiting rod 11. At the same time, the limiting rod 11 compresses the fixing plate 5 and squeezes the first spring 4. Under the reverse action force of the first spring 4, the fixing plate 5 pushes the limiting rod 11, so that the clamping groove of the limiting rod 11 can be closely fitted with the clamping rod 8, so that the stability of the limiting between the limiting rod 11 and the clamping rod 8 is better, so that the connection between the protective sleeve 10 and the first rubber sleeve 3 is more stable, which helps to protect the terminal head 2.

[0031] Installation grooves are provided on the upper and lower end surfaces of the first rubber sleeve 3, the first spring 4 is fixedly connected to the left inner wall of the installation groove of the first rubber sleeve 3, and the second spring 6 is fixedly connected to the right inner wall of the first rubber sleeve 3. The first spring 4 helps the fixing plate 5 to contact the limiting rod 11, so that the slot of the limiting rod 11 fits tightly with the clamping rod 8, which helps to improve the stability between the limiting rod 11 and the clamping rod 8. At the same time, the first spring 4 helps to reset the limiting rod 11, and the second spring 6 helps to make the clamping rod 8 shake, helps to make the limiting rod 11 stuck with it, and helps to reset the clamping rod 8.

[0032] A support rod 12 is fixedly connected to the inner wall at the bottom of the installation groove of the first rubber sleeve 3. The clamping rod 8 passes through the support rod 12 and is rotatably connected to the support rod 12. The support rod 12 can support the clamping rod 8, so that the clamping rod 8 can rotate and be clamped and limited by the limit rod 11.

[0033] A sliding groove is provided on the top surface of the first rubber sleeve 3, and the end of the L-shaped reset plate 9 away from the clamping rod 8 passes through the sliding groove of the first rubber sleeve 3 and is slidably connected to the sliding groove of the first rubber sleeve 3. By pushing the L-shaped reset plate 9 to slide along the sliding groove of the first rubber sleeve 3, the clamping rod 8 can be compressed to compress the second spring 6 through the connecting block 7, so that the clamping rod 8 rotates through the support rod 12 and disengages from the clamping groove of the limiting rod 11, thereby releasing the limit of the clamping rod 8 and the limiting rod 11, and then the protective sleeve 10 is separated from the first rubber sleeve 3, which is convenient for quick disassembly.

[0034] A guide groove is provided on the right inner wall of the first rubber sleeve 3, and a third spring 13 is fixedly connected to the inner wall of the guide groove of the first rubber sleeve 3. One end of the third spring 13 away from the inner wall of the guide groove of the first rubber sleeve 3 is fixedly connected to a guide rod 14, and one end of the guide rod 14 away from the third spring 13 is fixedly connected to the L-shaped reset plate 9. When the L-shaped reset plate 9 is pushed, the third spring 13 can be slidably compressed in the guide groove of the first rubber sleeve 3 by the guide rod 14, which helps to guide and support the L-shaped reset plate 9. The third spring 13 helps to reset the L-shaped reset plate 9 and prevents the L-shaped reset plate 9 from being too close to the clamping rod 8.

[0035] The end of the L-shaped reset plate 9 close to the connecting block 7 does not fit the connecting block 7. The L-shaped reset plate 9 does not fit the connecting block 7, which can prevent the clamping rod 8 from being unable to rotate and help the clamping rod 8 to rotate and limit the clamping groove of the limiting rod 11.

[0036] The surface of one end of the limiting rod 11 away from the protective sleeve 10 is a smooth arc surface, and the end of the clamping rod 8 away from the connecting block 7 is a smooth arc surface. The arc surface of the clamping rod 8 and the arc surface of the limiting rod 11 help the limiting rod 11 to enter the installation groove of the first rubber sleeve 3. The limiting rod 11 slides over the clamping rod 8 so that the clamping rod 8 is stuck in the clamping groove of the limiting rod 11.

[0037] A second rubber sleeve 15 is fixedly provided on the surface of the terminal head 2 at the right end of the connecting line 1, and two groups of limiting rods 11 and protective sleeves 10 are provided, and the two groups of limiting rods 11 and protective sleeves 10 are symmetrically arranged with the center line of the connecting line 1 as the symmetry axis. The two groups of limiting rods 11 and protective sleeves 10 help to make the connection between the protective sleeve 10 and the rubber sleeve more stable, thereby helping to protect the connecting line 1.

[0038] In the utility model, when it is necessary to perform a protective operation on the connecting line 1, the protective sleeve 10 drives the limiting rod 11 to enter the installation groove of the first rubber sleeve 3 and contact the clamping rod 8. The arc surface of the limiting rod 11 contacts the arc surface of the clamping rod 8, and cooperates with the second spring 6 to make the clamping rod 8 shake and pass. At the same time, the limiting rod 11 compresses the fixing plate 5 and the first spring 4, so that the clamping groove of the limiting rod 11 is clamped with the clamping rod 8. At this time, the first spring 4 applies a reverse thrust to the fixing plate 5 to make the fixing plate 5 push the limiting rod 11, so that the clamping groove of the limiting rod 11 is tightly fitted with the clamping rod 8, so that the connection between the clamping rod 8 and the limiting rod 11 is more stable, thereby making the connection between the protective sleeve 10 and the first rubber sleeve 3 more stable. The L-shaped reset plate 9 is pushed, and the L-shaped reset plate 9 slides in the guide groove on the inner wall of the mounting groove of the first rubber sleeve 3 through the guide rod 14, so that the L-shaped reset plate 9 contacts the connecting block 7 and compresses the second spring 6. Under the action of the support rod 12, the clamping rod 8 is rotated and disengaged from the clamping groove of the limiting rod 11, and then the L-shaped reset plate 9 is released. The third spring 13 automatically resets the L-shaped reset plate 9, and the first spring 4 assists the limiting rod 11 and the clamping rod 8 to release the limit through the fixing plate 5, so that the protective sleeve 10 is separated from the first rubber sleeve 3, thereby completing the quick disassembly and improving the work efficiency.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
