Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, specifically to a ring array grounding structure for conductor shielded terminals. Background Technology

[0002] In modern electronic and electrical systems, grounding technology is a key element in ensuring stable equipment operation and electromagnetic compatibility.

[0003] Traditional conductor-shielded terminal grounding structures often employ single-point grounding or simple linear connections. This design suffers from small contact area and high grounding impedance, making it difficult to effectively suppress high-frequency electromagnetic interference. When handling high-frequency signals such as 5G communications and radar systems, signal leakage and transmission loss frequently occur. Furthermore, existing grounding structures often rely on bolt fastening or welding, resulting in cumbersome installation processes. Single-point faults require complete disassembly and repair, leading to low construction and maintenance efficiency. Regarding the method of grounding electrode insertion, traditional straight-rod grounding devices experience high soil resistance, making it difficult to quickly and stably insert into hard clay layers or complex geological areas. They also have limited grounding area and high grounding resistance. In addition, traditional grounding structures are prone to displacement and loosening under the influence of environmental factors such as soil settlement and vibration, leading to grounding failure and seriously threatening equipment safety and signal quality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-4 This utility model provides a technical solution: a ring array grounding structure for conductor shielded terminals, comprising:

[0025] The connecting end 1 has an annular device 2 slidably connected to its outer wall. The annular device 2 is locked by rotation. The bottom end of the annular device 2 is fixedly connected to a grounding device 3. The wire is fixedly connected to the connecting end 1 and slidably connected to the sliding device. The grounding device 3 at the bottom end provides shielding.

[0026] The ring device 2 includes a receiving end 20. Contacts 21 are fixedly connected to the inner wall of the receiving end 20. The bottom ends of the contacts 21 are arranged in a circular array along the central axis of the receiving end 20. A connecting rod 22 is fixedly connected to the outer wall of the receiving end 20. The outer wall of the connecting rod 22 is arranged in a circular array along the central axis of the receiving end 20. A connecting ring 23 is fixedly connected to the end of the connecting rod 22 away from the receiving end 20. The inner wall of the connecting end 1 is slidably connected to the outer wall of the contacts 21, and the outer wall of the connecting end 1 is slidably connected to the inner wall of the receiving end 20. When the connecting end 1 is inserted into the receiving end 20, due to the sliding connection between the inner wall of the receiving end 20 and the outer wall of the contacts 21, the contacts 21 arranged in a circular array on the inner wall of the receiving end 20 are tightly fitted with the outer wall of the connecting end 1, forming a continuous ring conductive path. This design increases the grounding contact area by more than three times compared to single-point grounding, significantly reduces the grounding impedance, provides a low-resistance discharge path for high-frequency electromagnetic interference, and achieves efficient shielding.

[0027] A locking ring 24 is rotatably connected to the top of the receiving end 20. A retaining strip 25 is slidably connected to the inner wall of the locking ring 24. A curved groove 26 is symmetrically formed on the inner wall of the locking ring 24. A limit rod 27 is slidably connected to the inner wall of the curved groove 26. A lever 28 is fixedly connected to the outer wall of the locking ring 24. The outer wall of the retaining strip 25 is fixedly connected to the outer wall of the connecting end 1 and arranged in a circumferential array along the central axis of the connecting end 1. The bottom end of the limit rod 27 is fixedly connected to the top of the receiving end 20. When it is necessary to connect the connecting end 1 and the receiving end 20, the connecting end 1 will be connected... The connecting end 1 slides along the inner wall of the locking ring 24, and the locking strip 25 also slides along the inner wall of the locking ring 24. Since the outer wall of the locking ring 24 is fixedly connected to the lever 28, the lever 28 on the outer wall of the locking ring 24 is then moved, and the bottom end of the limiting rod 27 is fixedly connected to the bottom end of the receiving end 20, so that the locking ring 24 rotates 30 percent along the limiting rod 27 in the arc groove 26, thereby realizing the rapid locking of the ring device 2 and the connecting end 1. The sliding cooperation between the arc groove 26 and the limiting rod 27 allows the locking ring 24 to automatically fine-tune its position in the vibration environment.

[0028] The grounding device 3 includes a round rod 30, with a main cone 31 at its bottom end. A bulldozer block 32 is fixedly connected to the top of the main cone 31. The top of the round rod 30 is fixedly connected to the bottom of a connecting ring 23, and the tops of the round rod 30 are arranged in a circumferential array along the central axis of the connecting ring 23. The top of the bulldozer block 32 is fixedly connected to the bottom of the main cone 31. The main cone 31 at the bottom of the round rod 30 of the grounding device 3, in conjunction with the bulldozer block 32, allows the grounding device 3 to penetrate the ground during the process of penetration. The main cone 31 utilizes its sharp angle and inclined structure to reduce the soil penetration resistance. With reduced force, it can penetrate hard clay layers and quickly insert into the ground. When the ground height reaches the bulldozer block 32 and continues to move upward, the secondary cone 34 on the outer wall of the round rod 30 is subjected to lateral soil compression during the soil insertion process due to the structure of the bulldozer block 32. It rotates around the fixed block 33 and unfolds to 45%. Due to the contact between the baffle 35 and the outer wall of the secondary cone 34, the secondary cone 34 forms an umbrella-shaped grounding network. This structure makes the equivalent grounding area larger than that of a traditional straight rod, further reducing the grounding resistance, and at the same time providing multi-point anchoring during soil settlement.

[0029] A fixing block 33 is fixedly connected to the outer wall of the round rod 30. The outer wall of the fixing block 33 is arranged in a circumferential array along the central axis of the round rod 30. A secondary pointed cone 34 is rotatably connected to the inner wall of the fixing block 33. A stop bar 35 is fixedly connected to the inner wall of the fixing block 33. The outer wall of the stop bar 35 is in contact with the outer wall of the secondary pointed cone 34.

[0030] When in use, the wire is fixedly connected to the connecting end 1 and slidably connected to the sliding device, and shielding is performed through the grounding device 3 at the bottom.

[0031] When the connector 1 is inserted into the receiver 20, the inner wall of the receiver 20 is slidably connected to the outer wall of the contact 21. The contacts 21 arranged in a circular array on the inner wall of the receiver 20 are tightly attached to the outer wall of the connector 1, forming a continuous ring conductive path. This design increases the grounding contact area by more than three times compared to single-point grounding, significantly reduces the grounding impedance, provides a low-resistance discharge path for high-frequency electromagnetic interference, and achieves efficient shielding.

[0032] When it is necessary to connect the connecting end 1 and the receiving end 20, the connecting end 1 is slid along the inner wall of the locking ring 24, and the locking strip 25 also slides along the inner wall of the locking ring 24. Since the outer wall of the locking ring 24 is fixedly connected to the lever 28, the lever 28 on the outer wall of the locking ring 24 is then moved, and the bottom end of the limiting rod 27 is fixedly connected to the bottom end of the receiving end 20, so that the locking ring 24 rotates 30 percent along the limiting rod 27 in the arc groove 26, thereby realizing the rapid locking of the ring device 2 and the connecting end 1. The sliding cooperation between the arc groove 26 and the limiting rod 27 allows the locking ring 24 to automatically fine-tune its position in the vibration environment.

[0033] The main cone 31 at the bottom of the round rod 30 of the grounding device 3 works in conjunction with the bulldozer block 32. During the process of the grounding device 3 penetrating the ground, the main cone 31 uses its sharp angle and inclined structure to reduce the resistance to soil penetration, allowing it to penetrate the hard clay layer and quickly insert into the ground. When the ground height reaches the bulldozer block 32 and continues to move upward, the secondary cone 34 on the outer wall of the round rod 30 is subjected to lateral compression by the soil during the soil penetration process due to the structure of the bulldozer block 32. It rotates around the fixed block 33 and unfolds to 45%. Since the baffle 35 contacts the outer wall of the secondary cone 34, the structure of the baffle 35 causes the secondary cone 34 to form an umbrella-shaped grounding network. This structure makes the equivalent grounding area larger than that of a traditional straight rod, further reducing the grounding resistance, and at the same time providing multi-point anchoring during soil settlement.

[0034] After an accidental current is transmitted to the ring device 2, it can be quickly conducted to the round rod 30 through the connecting rod 22 and the connecting ring 23, and the current can be safely and efficiently introduced into the ground by utilizing the large-area contact between the grounding device 3 and the soil.
