Description

Technical Field

[0001] This utility model relates to the field of grounding post structure technology, specifically a suspended grounding post structure. Background Technology

[0002] In today's rapidly evolving electronic equipment landscape, higher demands are placed on the environmental adaptability of electronic devices. The quality of grounding in a large system directly impacts the EMC (electromagnetic compatibility) test results. Even with individually designed insulated components, existing grounding posts still need to penetrate the equipment casing. Through-holes allow rainwater to seep into the casing through the grounding post threads and installation gaps, or the grounding post and casing may become connected by rainwater. In this case, the signal ground and casing ground are connected together; simultaneously, interference signals from the casing ground can enter the signal ground, causing EMC disruptions; in severe cases, it can even interfere with the entire system or cause instability in certain functions. Utility Model Content

[0003] The purpose of this invention is to provide a floating grounding post structure to solve the problem of poor accuracy and stability of detection data caused by the contact between the signal ground and the metal casing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a suspended grounding post structure, comprising: an upper connecting part disposed above a mounting panel; a lower connecting part extending upward from below the mounting panel and contacting the upper connecting part to transmit electrical signals; and an isolation structure made of insulating material, comprising an upper isolation member and a lower isolation member, wherein the upper isolation member is disposed between the upper connecting part and the mounting panel, and the lower isolation member is disposed between the lower connecting part and the mounting panel.

[0005] As a further improvement to the above technical solution:

[0006] A sealing ring is provided between the lower isolation component and the mounting panel.

[0007] The mounting panel is provided with a mounting groove for accommodating the sealing ring.

[0008] The upper connecting part has a through hole structure, and the lower connecting part passes through the upper connecting part and is connected to a pressure block.

[0009] The pressure block and the lower connecting part are threaded together.

[0010] The upper connecting part is a non-through hole structure. A wiring connecting post is provided above the upper connecting part, and a pressure block is provided on the wiring connecting post. The wiring connecting post and the pressure block are threaded together.

[0011] The lower connecting part includes an upper threaded section, a lower threaded section, and a middle support plate, and the lower isolation member is wrapped around the middle support plate.

[0012] The lower isolation component is fitted onto the upper threaded section and is located between the mounting panel and the lower connecting part.

[0013] The lower thread section is threaded with a ground nut.

[0014] The upper connecting part and the upper isolation part are integrally injection molded, and the lower connecting part and the lower isolation part are integrally injection molded.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Simplified structure and easy installation: By injection molding the upper connecting part and the upper isolation part, and the lower connecting part and the lower isolation part into one piece, the overall structure is simplified, containing only two main components, which greatly improves assembly efficiency and reduces installation difficulty.

[0017] Excellent insulation performance: The isolation structure made of insulating material effectively isolates the electrical contact between the upper and lower connecting parts and the mounting panel, preventing interference signals from the housing ground from entering the signal ground, thereby ensuring the accuracy and stability of the test data.

[0018] Excellent sealing performance: A sealing ring is installed between the lower isolation component and the mounting panel, and the sealing ring is limited by the mounting groove, which effectively reduces the intrusion of rainwater and dust when used outdoors, and improves the environmental adaptability and service life of the equipment.

[0019] Material savings and cost reduction: The one-piece injection molding design not only simplifies the structure but also reduces the number of parts, thereby saving materials and reducing production costs.

[0020] Enhanced safety: The use of insulating components effectively avoids the risk of accidental electric shock caused by the transmission of electrical signals, thus improving the safety of the equipment.

[0021] In summary, the floating grounding post structure of this embodiment achieves multiple beneficial effects such as simplified structure, convenient installation, good sealing performance, high safety, and low cost while ensuring electrical performance, and has broad application prospects and promotional value.

[0028] 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.

[0029] Example 1

[0030] like Figure 1 and Figure 2As shown, the floating grounding post structure of this embodiment includes: an upper connecting part 1, disposed above the mounting panel 5; a lower connecting part 2, extending upwards from below the mounting panel 5 and contacting the upper connecting part 1 to transmit electrical signals; this contact is typically a connection, such as a snap-fit ​​or threaded connection; and an isolation structure made of insulating material, including an upper isolation member 3 and a lower isolation member 4. The upper isolation member 3 is disposed between the upper connecting part 1 and the mounting panel 5, and the lower isolation member 4 is disposed between the lower connecting part 2 and the mounting panel 5. For ease of assembly, the upper connecting part 1 and the upper isolation member 3 are integrally injection molded, as are the lower connecting part 2 and the lower isolation member 4. After injection molding, it essentially consists of two parts, facilitating installation. The integrated design reduces the number of parts, making installation simple and quick; at the same time, the injection molding design greatly reduces processing time, making it suitable for mass production, with different specifications and models available for users to choose from. The insulating material of the isolation structure can be rubber, wood, insulating coating, insulating plastic, etc. When using wood, insulating coating, or rubber, integral molding is not possible; the insulating coating can be directly applied to non-connecting parts of the equipment. Insulating plastic materials can be used for one-piece injection molding.

[0031] A sealing ring 6 is provided between the lower isolation component 4 and the mounting panel 5. The sealing ring 6 reduces the probability of rainwater and dust entering when used outdoors.

[0032] The mounting panel 5 is provided with a mounting groove 51 for accommodating the sealing ring 6. The mounting groove 51 is used to limit the sealing ring 6, which can improve the sealing effect.

[0033] The upper connecting part 1 is a non-through hole structure. A wiring connecting post 8 is provided above the upper connecting part 1. A pressure block 7 is provided on the wiring connecting post 8. The wiring connecting post 8 and the pressure block 7 are threaded together.

[0034] The lower connecting part 2 includes an upper threaded section, a lower threaded section and a middle support plate, and the lower isolation member 4 is wrapped around the middle support plate.

[0035] The lower isolation component 4 is fitted onto the upper threaded section and is located between the mounting panel 5 and the lower connecting part 2.

[0036] The lower thread section is fitted with a ground nut 9.

[0037] In use, the upper connecting part 1 (with upper isolator 3) is located inside the housing, above the mounting panel 5, and the lower connecting part 2 (with lower isolator 4) is located outside the housing, below the mounting panel 5. The sealing ring 6 is installed into the mounting groove 51, and the head of the lower connecting part 2 is inserted into the mounting hole, making it threadedly connected to the upper connecting part 1. Then, the internal grounding wire can be installed using the pressure block 7, and the external grounding wire is installed using the ground nut. The insulating isolator insulates the metal conductive components from the mounting panel, preventing interference signals from the housing ground from entering the signal ground and affecting the detection data. External rainwater cannot enter the housing. After the upper part of the lower connecting part 2 passes through the mounting panel 5, the lower isolator 4 forms a clearance fit with the mounting panel 5 (i.e., the housing), ensuring good insulation even if assembly errors cause contact. If higher insulation strength is required, the contact area can be reduced, or a thicker insulating material can be designed, or a material with higher insulation properties can be selected. At this point, from a conductivity perspective, the signal ground is suspended above the housing ground.

[0038] Example 2

[0039] Unlike Embodiment 1, the upper connecting part 1 has a through hole structure, and the lower connecting part 2 passes through the upper connecting part 1 and is connected to the pressure block 7. The pressure block 7 and the lower connecting part 2 are threaded together.

[0040] In this embodiment, the lower connecting part 2 directly penetrates the upper connecting part 1, and the upper connecting part 1 can be made of a conventional nut without the need for separate structural design.

[0041] This invention's floating grounding post structure integrates the metal grounding material and the insulator in a die-casting mold, thus isolating the metal from direct contact with the metal chassis and achieving a floating grounding post effect. Common grounding posts are typically directly connected to the metal chassis; however, they cannot meet specific grounding requirements when isolation between the signal ground and the chassis ground is needed. This type of grounding post, once successfully implemented in engineering practice, can be mass-produced; installation is very simple and quick according to the provided opening requirements.

[0042] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
