Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and more specifically, it relates to a sealed rectangular connector. Background Technology

[0002] In electronic devices and communication systems, sealed rectangular connectors are critical signal and current transmission components, and their performance directly affects the stability and reliability of the entire system.

[0003] In terms of sealing performance, traditional rectangular connectors have relatively simple sealing structures, often employing a single sealing method, such as relying solely on a sealing ring. This results in poor sealing performance, and traditional rectangular connectors also have inadequate shielding, affecting their lifespan and transmission performance. Therefore, this paper researches and improves upon existing structures and shortcomings to provide a sealed rectangular connector, aiming to achieve greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sealed rectangular connector, which is achieved by the following specific technical means:

[0005] A sealed rectangular connector includes an insulating base and a socket. The socket has a protrusion and a sleeve portion. The protrusion is located inside the sleeve portion. An insulating frame is mounted on the insulating base. A plurality of terminal bodies are disposed within the insulating frame. A plurality of slots adapted to the terminal bodies are fitted onto the surface of the protrusion. A plurality of rubber sleeves are disposed within the insulating frame. Each rubber sleeve is fixedly fitted onto a terminal body. The protrusion is inserted into the insulating frame. A raised frame is provided at the insulating frame. The sleeve portion is fitted onto the raised frame. A sealing ring is fitted onto the raised frame. A shielding assembly is disposed between the insulating base and the insulating frame. The shielding assembly includes a shielding plate and a conductive plastic plate. The conductive plastic plate is fixedly mounted on the insulating base. The shielding plate is fixedly mounted between the conductive plastic plate and the insulating frame.

[0006] Furthermore, both the shielding plate and the conductive plastic plate have openings on their surfaces, and the terminal bodies are fixedly inserted through the insulating frame and the insulating base. The terminal bodies include signal terminals and grounding terminals.

[0007] Furthermore, the grounding terminal is fixedly inserted through the shielding plate and the conductive plastic plate, and the signal terminal is inserted through the port.

[0008] Furthermore, each of the terminal bodies has a solder ball at its end.

[0009] Furthermore, a screw is provided between the insulating base and the socket, and the insulating base is threadedly fixed to the socket by the screw.

[0010] Furthermore, each of the slots is provided with a groove that is adapted to the rubber sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] I. This sealed rectangular connector adopts a double-sealing design, which can effectively block external interference. The first sealing line consists of a sealing ring fitted on the raised frame. Under the squeezing action of the fitted part and the raised frame, the sealing ring deforms and tightly fills the gap between the two, which can effectively prevent external dust, moisture and other impurities from entering the connector. The second sealing structure is formed by the tight fit between the rubber sleeve and the groove. The rubber sleeve is fixedly fitted on the terminal body. When the terminal body is inserted into the slot, the rubber sleeve enters the groove, further enhancing the overall sealing performance and providing a good protective environment for the internal components of the connector.

[0013] II. The shielding assembly consists of a shielding plate and a conductive plastic plate, which can effectively reduce signal interference and ensure signal transmission quality. The grounding terminal is fixedly connected through the shielding plate and the conductive plastic plate, so that the originally independent grounding terminals are connected into a whole through the shielding plate. The various grounding terminals are interconnected, which fundamentally reduces the generation of grounding resonance. At the same time, the shielding plate is directly connected to the conductive plastic plate, which can quickly absorb and eliminate any possible resonance energy, further suppressing the resonance phenomenon.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a sealed rectangular connector, including an insulating base 1 and a socket 2. The socket 2 is provided with a protrusion 21 and a sleeve 22. The socket 2, the protrusion 21 and the sleeve 22 are all made of insulating material. The protrusion 21 is located inside the sleeve 22. An insulating frame 11 is installed on the insulating base 1. A plurality of terminal bodies 13 are provided inside the insulating frame 11. A plurality of slots that are adapted to the terminal bodies 13 are provided on the surface of the protrusion 21. The protrusion 21 is inserted into the insulating frame 11. A protrusion frame 12 is provided at the insulating frame 11. The sleeve 22 is sleeved on the protrusion frame 12. A sealing ring 3 is sleeved on the protrusion frame 12. The sealing ring 3 deforms under the squeezing action of the sleeve 22 and the protrusion frame 12, thereby forming a first sealing barrier between the sleeve 22 and the insulating frame 11, effectively preventing external dust, moisture and other impurities from entering the connector.

[0026] A shielding assembly is provided between the insulating base 1 and the insulating frame 11. The shielding assembly includes a shielding plate 5 and a conductive plastic plate 6. The conductive plastic plate 6 is fixedly installed on the insulating base 1, and the shielding plate 5 is fixedly installed between the conductive plastic plate 6 and the insulating frame 11.

[0027] Both the shielding plate 5 and the conductive plastic plate 6 have openings 7 on their surfaces. The signal terminals pass through the openings 7 on the surfaces of the shielding plate 5 and the conductive plastic plate 6, avoiding direct contact between the signal terminals and the shielding components and preventing signal interference.

[0028] The terminal body 13 is fixedly inserted through the insulating frame 11 and the insulating base 1. The terminal body 13 includes signal terminals and grounding terminals.

[0029] The grounding terminal is fixed through the shielding plate 5 and the conductive plastic plate 6, and the signal terminal passes through the opening 7;

[0030] Each terminal body 13 has a solder ball 8 at its end, which can effectively improve the soldering effect with the circuit board.

[0031] A screw 9 is provided between the insulating base 1 and the socket 2. The insulating base 1 is fixed to the socket 2 by the screw 9, making the connection between the two more secure and preventing the connection from loosening due to vibration and other factors during use, thus ensuring the sealing performance and the stability of the electrical connection.

[0032] The insulating frame 11 is provided with several rubber sleeves 4. Each rubber sleeve 4 is fixedly fitted on the terminal body 13. Each slot has a groove 23 that matches the rubber sleeve 4. The tight fit between the rubber sleeve 4 and the groove 23 forms a second sealing structure, which further enhances the overall sealing performance.

[0033] The working principle of this embodiment:

[0034] Step 1: When mating the connector, the protrusion 21 on the socket 2 is precisely inserted into the insulating frame 11. During this process, the terminal body 13 is simultaneously inserted into the corresponding slot on the surface of the protrusion 21, realizing the initial mating of the signal and current transmission channels. At the same time, the sleeve 22 is tightly fitted onto the protrusion 12. Since the sealing ring 3 is fitted on the protrusion 12, the sealing ring 3 deforms under the squeezing action of the sleeve 22 and the protrusion 12, thus forming the first sealing barrier between the sleeve 22 and the insulating frame 11, effectively preventing external dust, moisture and other impurities from entering the connector. The rubber sleeve 4 fixedly fitted on the terminal body 13 is inserted into the groove 23 at the slot along with the terminal body 13. The tight fit between the rubber sleeve 4 and the groove 23 forms the second sealing structure, further enhancing the overall sealing performance. Finally, the insulating seat 1 and the socket 2 are threadedly fixed by the screw 9, making the connection between the two more secure, preventing the connection from loosening due to vibration and other factors during use, and ensuring the sealing performance and the stability of the electrical connection.

[0035] Step 2: The grounding terminal is fixed through the shielding plate 5 to achieve a fixed connection between the grounding terminal and the shielding plate 5. The independent grounding terminals are connected into a whole through the shielding plate 5. The grounding terminals are interconnected through the shielding plate 5, which can fundamentally and effectively reduce the generation of grounding resonance. The shielding plate 5 is directly connected to the conductive plastic plate 6. The conductive plastic plate 6 can effectively absorb and eliminate the possible resonance energy and ensure the integrity of signal transmission. Each terminal body 13 has a solder ball 8 fixedly connected to its end. The solder ball 8 can effectively improve the soldering effect with the circuit board.
