Description

Technical Field

[0001] The invention relates to the technical field of component maintenance tools, and in particular to a conductive plug-in quick assembly and disassembly mechanism and a use method thereof. Background Art

[0002] Conduction heat dissipation plug-ins are referred to as conduction plug-ins. When they are used and repaired, they often need to be assembled and disassembled. At the same time, efficient heat dissipation during the operation of the conduction plug-in must be ensured. The blind-plug connectors used in the conduction plug-in require a large plug-in and pull-out force, which cannot be accomplished by hand alone.

[0003] At present, the insertion and locking of the conductive plug-in are effective, and the puller is used together with the locking strip, such as the UAV load plug-in chassis that uses conduction and air cooling to dissipate heat, as described in publication number CN112492845A. The wedge-shaped mechanism is first used to push the plug-in in, and then the locking strip is tightened by screws to provide sufficient clamping force for the side wall of the plug-in to ensure its heat dissipation. The high complexity of the installation and disassembly operations, the long time of the screw tightening process, and the need for auxiliary tools to tighten the screws will reduce the reliability of the equipment during use, and also make it extremely inconvenient for personnel during debugging and disassembly.

[0004] Another example is a locking strip floating installation mechanism and installation method described in publication number CN107979940A, which uses a one-piece locking strip with a handle to solve the problem of the locking strip itself getting stuck. However, this form cannot provide a driving force during insertion. When a driving force is required for the insertion of the plug-in, an independent puller still needs to be installed, which is inconvenient to operate.

[0005] Based on the search of the above information, it can be seen that the current installation of the conductive plug-in has the problems of high complexity of disassembly operation and long time of screw tightening process. Therefore, a conductive plug-in quick assembly and disassembly mechanism and a use method are proposed to realize the quick assembly and disassembly of the conductive plug-in, improve the convenience of debugging and maintenance and the reliability of the equipment, Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a conductive plug-in quick assembly and disassembly mechanism and a method of use, which solves the problems of high complexity of disassembly operations and long time of screw tightening process in the current installation of the conductive plug-in.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a conductive plug-in quick assembly and disassembly mechanism, including a chassis and a conductive plug-in inserted in the chassis, a quick-release component is fixedly installed on the top of the conductive plug-in, a chassis slot is fixedly installed on one side of the chassis, and the quick-release component is used in conjunction with the chassis slot.

[0008] The present invention is further configured as follows: the quick-release assembly includes a base, a front baffle is sleeved and slidably mounted on the outer periphery of one end of the base, a plurality of wedge-shaped blocks used in conjunction are slidably mounted on the top and bottom of the base, and a handle is rotatably mounted on one end of the base through a rivet; The front side of the base is fixedly mounted on the conductive plug-in by means of bolts, and the front side of the base is provided with a plurality of mounting holes used in conjunction with the bolts.

[0009] The present invention is further configured as follows: a threaded sleeve is fixedly connected to the other end of the base, one end of the threaded sleeve passes through and is threadedly installed with a limit screw, the outer periphery of the limit screw is sequentially sleeved with a rear baffle and a disc spring from left to right, and the two ends of the disc spring are respectively fixedly connected to the hollow rear baffle and the side opposite to the limit screw.

[0010] The present invention is further configured as follows: a first cam is integrally formed on the top of the handle, and a slot rear outer edge and a slot front outer edge which cooperate with the first cam are respectively provided on both sides of the inner cavity of the chassis slot.

[0011] The present invention is further configured as follows: a second cam is integrally formed at the bottom of the handle, and the second cam is used in conjunction with the front baffle.

[0012] The present invention is further configured as follows: a step slide groove is provided on the top and bottom of the base, the opposite sides of the two wedge blocks arranged at the top and the bottom are fixedly connected with a first slider used in conjunction with the step slide groove, and the opposite sides of the two first sliders arranged at the top and the bottom are fixedly connected with a second slider.

[0013] The present invention is further configured as follows: a return spring is fixedly connected between the front and rear sides of the second sliding block and the front and rear sides of the inner cavity of the stepped slide groove.

[0014] The present invention also discloses a method for using the conductive plug-in quick assembly and disassembly mechanism, which specifically comprises the following steps: Step 1: Insert the conductive plug-in and the quick-release assembly into the chassis together. After the first cam moves to between the rear outer edge of the slot and the front outer edge of the slot, turn the handle to make the first cam squeeze the front outer edge of the slot. Under the reaction force, the handle pushes the base to move into the chassis. When the handle is turned counterclockwise to forty-five degrees, the distance between the front outer edge of the slot and the center of the first cam is the maximum distance between the two contact features. After that, continue to turn the handle, the first cam and the front outer edge of the slot will remain tangent, and the quick-release assembly and the conductive plug-in will stop at the current position, that is, the conductive plug-in is inserted in place. Step 2: When the handle pushes the base to move into the chassis in step 1, the second cam squeezes the front baffle, and the front baffle squeezes the wedge block. The wedge block moves forward and backward respectively under the limit guide of the inclined surface of another adjacent wedge block. The wedge block drives the first slider to move forward and backward. During the process, the first slider drives the second slider to squeeze the return spring on one side and compress the return spring on the other side. When the handle is turned counterclockwise to forty-five degrees in step 1, the rightmost wedge block contacts the rear baffle; Step 3: Continue to turn the handle, the second cam pushes the front baffle to continue to squeeze the wedge block, at this time, the rightmost wedge block pushes the rear baffle to squeeze the disc spring, when the handle is turned to 90 degrees, the conductive plug-in is in a locked state; Step 4. When you need to pull out the conduction plug-in, first turn the handle forty-five degrees clockwise, the second cam stroke becomes shorter, the disc spring resets, the reset spring resets, and the handle continues to be turned clockwise. At this time, the first cam squeezes the rear outer edge of the groove. Under the reaction force, the handle pulls the base to move outside the chassis. Continue to turn it to pull out the conduction plug-in.

[0015] The present invention provides a conductive plug-in quick assembly and disassembly mechanism and a method of use. It has the following beneficial effects: The present invention provides leverage points for assembly and disassembly between the base and the chassis through the cooperation of the chassis slot, the first cam, the second cam and the handle, which facilitates the stable insertion of the conductive plug-in into the chassis and the convenient removal of the conductive plug-in from the chassis. In addition, through the cooperation of a plurality of wedge blocks, a front baffle, a rear baffle and a disc spring, the second cam is locked and the stable contact between the conductive plug-in and the chassis can be ensured by the movement of the wedge block. While ensuring the reliability of the equipment, it is easy to use and has the advantage of convenient assembly and disassembly, which effectively improves the convenience of debugging and maintenance.

In order to ensure the stable movement and convenient reset of the wedge block 9, a return spring 18 is fixedly connected between the front and rear sides of the second slider 13 and the front and rear sides of the inner cavity of the stepped slide groove 11. In order to ensure the stability of the second slider 13, at least three groups of return springs 18 are arranged on both sides of the same second slider 13. A second cam 21 is integrally formed at the bottom of the handle 6, and the second cam 21 is used in conjunction with the front baffle 8. In this way, when the handle 6 is rotated, the second cam 21 squeezes the front baffle 8, which can squeeze the wedge block 9. With the cooperation of the stepped slide groove 11 and the second slider 13, it is ensured that the wedge block 9 can only move forward and backward or left and right. When the front baffle 8 squeezes the leftmost wedge block 9, it can push the subsequent several wedge blocks 9 to move to the right first, and then with the cooperation of the inclined surfaces of the two adjacent wedge blocks 9, the several wedge blocks 9 are moved forward or backward respectively.

Figure 4 As shown in FIG. B, under the reaction force, the handle 6 pushes the base 20 to move into the chassis 10. When the handle 6 is rotated counterclockwise to 45 degrees, as shown in FIG. Figure 4 As shown in Figure C, the distance between the center of the first cam 7 and the front outer edge 5 of the groove is the maximum distance between the two contact features. After that, the handle 6 is continuously rotated, and the first cam 7 and the front outer edge 5 of the groove will maintain a tangent state, and the quick release assembly 2 and the conductive plug-in 3 stop at the current position, that is, the conductive plug-in 3 is inserted in place; Step 2. When the handle 6 pushes the base 20 to move into the chassis 10 in step 1, the second cam 21 squeezes the front baffle 8, and the front baffle 8 squeezes the wedge block 9. The wedge block 9 moves in the front and rear directions respectively under the limit guide of the inclined surface of another adjacent wedge block 9. The wedge block 9 drives the first slider 12 to move forward and backward. During the process, the first slider 12 drives the second slider 13 to squeeze the return spring 18 on one side and compress the return spring 18 on the other side. When the handle 6 is turned counterclockwise to forty-five degrees in step 1, as shown in the attached figure Figure 4 As shown in Figure C, the rightmost wedge block 9 is in contact with the rear baffle 17; Step 3: Continue to turn the handle 6, the second cam 21 pushes the front baffle 8 to continue to squeeze the wedge block 9. Figure 4 As shown in FIG. D, the rightmost wedge block 9 pushes the rear baffle 17 to squeeze the disc spring 15. When the handle 6 is rotated to 90 degrees, as shown in FIG. Figure 4 As shown in Figure E, the conductive plug 3 is in a locked state; Step 4: When the conductive plug-in 3 needs to be pulled out, the handle 6 is first turned 45 degrees clockwise, the stroke of the second cam 21 becomes shorter, the disc spring 15 is reset, the reset spring 18 is reset, and the handle 6 is continued to be turned clockwise. At this time, the first cam 7 squeezes the rear outer edge 4 in the groove, as shown in the attached figure. Figure 4 As shown in FIG. F, under the reaction force, the handle 6 pulls the base 20 to move outside the chassis 10, and the conductive plug-in 3 can be pulled out by continuing to rotate.
