Description

Technical Field

[0001] This utility model relates to the field of electronic mechanical engineering technology, specifically a quick-release grounding post. Background Technology

[0002] Military electronic equipment typically uses a threaded grounding post, where the grounding wire is secured to the post with a threaded nut or similar component. Installing the grounding wire requires manually unscrewing the nut, fitting the pre-drilled end of the grounding wire onto the threaded rod of the grounding post, and then screwing the nut back onto the rod to tighten the grounding wire. This entire process takes approximately 10 seconds. Removing the grounding wire is done in the reverse order, also taking about 10 seconds. To ensure proper tightening of the grounding post nut, there should be at least enough space in front of the grounding post to allow for hand-holding. The nut on the threaded grounding post needs to be removed during operation. To prevent loss, it is usually designed with a spring-loaded contact spring connected to the grounding post. This spring needs to be bent; if the surface treatment is inadequate, it can harden and break easily. Threaded grounding posts typically use metric M4 threads. However, threads have a limited lifespan. For general mechanical products, threaded fasteners must be replaced after 5-6 installations and removals to ensure a secure connection. Grounding posts, however, are used far more than 5-6 times, potentially hundreds of times. Therefore, the threads on grounding posts are easily damaged after prolonged use. Currently, threaded grounding posts are generally made of austenitic stainless steel with a passivated outer surface to improve strength. However, stainless steel does not have the best electrical conductivity among metals. Therefore, grounding posts made of stainless steel are prone to exceeding grounding resistance limits, resulting in poor grounding performance for the equipment.

[0003] In light of the problems with existing threaded grounding posts, there is a need to develop a grounding post product that is quick to install and remove, easy to operate, not easily damaged, and has good conductivity. Utility Model Content

[0026] Please see Figure 1-7 This utility model provides a technical solution:

[0027] A quick-release grounding post includes a pressure block 1, a clamping plate 2, a torsion spring 3, and a connecting wire 10. The torsion spring 3 has shaft through holes 33 at its center on both sides. The clamping plate 2 is located at the rear end of the torsion spring 3. A third shaft seat 21 and a fourth shaft seat 22 are respectively located on the top two sides of the back of the clamping plate 2. Riveting countersunk holes 23 are located at the center on both sides of the third shaft seat 21 and the fourth shaft seat 22, corresponding to the shaft through holes 33. The pressure block 1 is located at the front end of the torsion spring 3, and a first... The first rotating shaft seat 13 and the second rotating shaft seat 14 are connected. The outer side of the first rotating shaft seat 13 is in contact with the inner side of the third rotating shaft seat 21, and the inner side of the second rotating shaft seat 14 is in contact with the outer side of the fourth rotating shaft seat 22. Through holes are provided at the center of both sides of the first rotating shaft seat 13 and the second rotating shaft seat 14. The through holes correspond to the riveting countersunk holes 23. The rotating shaft 4 is provided at the through hole 33, the riveting countersunk hole 23 and the through hole. The two ends of the torsion spring 3 are the first hook 31 and the second hook 32, respectively. The first hook 31 and the second hook 32 hook the pressure block 1 and the clamping plate 2, respectively.

[0028] Furthermore, a screw through hole 24 is provided through the bottom front of the clamping plate 2, a pressure plate 12 is provided on the inner side of the pressure block 1 corresponding to the screw through hole 24, and a handle 11 is provided on the front of the pressure block 1 corresponding to the pressure plate 12.

[0029] Furthermore, a screw 5 is provided inside the screw through hole 24. The screw 5 includes a lap joint positioning boss 51, a limiting boss 52, and a fixing screw 53. The fixing screw 53 is located inside the screw through hole 24. The limiting boss 52 is provided on the surface of the fixing screw 53 and on the back of the clamping plate 2. The back of the limiting boss 52 is in contact with the back of the clamping plate 2. The front end of the limiting boss 52 is provided with the lap joint positioning boss 51.

[0030] Furthermore, a welding plate 9, a spring washer 8, and a flat washer 7 are arranged sequentially from the inside to the outside on the front end of the fixing screw 53 located on the front side of the clamping plate 2. A nut 6 is sleeved on the surface of the fixing screw 53, and the back of the nut 6 is in contact with the front of the flat washer 7.

[0031] Specifically, the fixing screw 53 and the limiting boss 52 of the screw 5 pass through the screw through hole 24 of the clamping plate 2. The nut 6, flat washer 7, and spring washer 8 are connected and fixed to the fixing screw 53 on the screw 5, which is used for the quick-release grounding post to be installed on the equipment. The welding piece 9 is used for the connection between the inside of the equipment and the casing ground.

[0032] Furthermore, mounting holes are provided at both ends of the lap joint 10, one of which is located at the lap joint positioning boss 51.

[0033] Furthermore, the two ends of the rotating shaft 4 are respectively provided with a semi-circular rivet head 41 and an expansion rivet hole 42. The semi-circular rivet head 41 is close to the third rotating shaft seat 21 of the clamping plate 2, and the expansion rivet hole 42 is exposed in the riveting countersunk hole 23. Since the hooks 31 and 32 at both ends of the torsion spring 3 hook the pressure block 1 and the clamping plate 2 respectively, the expansion rivet hole 42 is expanded and riveted open, thus completing the riveting process between the pressure block 1 and the clamping plate 2.

[0034] Working principle: When installing the connecting cable 10, the operator pinches the handle 11 on the pressure block 1, overcoming the torsional force of the torsion spring 3, and pulls it upwards to expose the connecting cable positioning boss 51 on the screw 5. The mounting hole of the connecting cable 10 is then fitted onto the connecting cable positioning boss 51. The operator releases the handle 11, and under the torsional force of the torsion spring 3, the pressure plate 12 on the pressure block 1 firmly presses the connecting cable 10, completing the installation of the connecting cable 10 on the grounding post. To remove the connecting cable 10, the operator pinches the handle 11 on the pressure block 1, overcoming the torsional force of the torsion spring 3, and pulls it upwards to expose the connecting cable 10. The connecting cable 10 is then removed from the connecting cable positioning boss 51. The operator releases the handle 11, and under the torsional force of the torsion spring 3, the pressure block 1 returns to its initial position. Both the installation and removal of the connecting cable 10 take very little time, approximately one second.

[0035] Under the torsional force of the torsion spring 3, the contact wire 10 and the grounding post maintain good contact at all times. The outer surfaces of the pressure block 1, clamping plate 2, torsion spring 3, rotating shaft 4, and screw 5 are all gold-plated, giving the parts excellent conductivity and ensuring good grounding effect of the grounding post.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
