Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a connector assembly with a waterproof sealing structure. Background Technology

[0002] Connectors, as key components for signal and power transmission in electronic devices, are widely used in communication equipment, industrial control, automotive electronics, and consumer electronics. Their performance directly affects the reliability, safety, and user experience of these devices. With the miniaturization, high-density integration, and high-frequency / high-speed development of electronic devices, connector components face higher technical requirements, such as… Authorized publication number CN219350820U discloses a connector assembly. The locking device has a fixing groove inside. Before the plug and socket are inserted, the fixing groove engages with the locking retaining device, fixing the locking retaining device in a first state. The locking device includes a pressure block. After the plug and socket are inserted, the pressure block disengages the locking retaining device from the fixing groove, fixing the locking retaining device in a second state. This design, in order to unlock the plug and socket, first requires retracting the locking retaining device and then applying further force to the locking device to achieve unlocking and disengagement, ensuring the safety of the connector. Furthermore, this utility model has the advantages of simple structure, which facilitates production and saves costs.

[0003] However, existing connector assemblies rely solely on a single O-ring seal to fill the connection between the male and female connectors. This makes the seal prone to failure under the influence of external environmental factors such as ultraviolet light during long-term use, allowing moisture to easily penetrate the interior of the male and female connectors and affecting their stability. Therefore, in order to address the above problems, there is an urgent need for innovative design based on the existing connector components. Utility Model Content

[0004] The purpose of this invention is to provide a connector assembly with a waterproof sealing structure to solve the problem mentioned in the background art that current connector assemblies rely solely on a single O-ring to fill the connection between the male and female connectors. This leads to the O-ring easily failing under the influence of external environmental factors such as ultraviolet light during long-term use, resulting in moisture and other substances easily penetrating the interior of the male and female connectors and affecting their operational stability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a connector assembly with a waterproof sealing structure, comprising: a male connector body, and a pin disposed inside the male connector body, wherein a female connector body is connected to the right side of the male connector body, and a slot is provided inside the female connector body; Also includes: The first waterproof ring is attached to the right side surface of the pin, and a second waterproof ring is provided on the right side of the first waterproof ring. A first guide block is provided on the outer side of the male head body, and a connecting block is provided on the outer side of the first guide block. A shock-absorbing pre-tightening component is provided on the inner side of the female head body, and a fourth waterproof ring is provided on the right side of the female head body. The third guide block is installed on the outside of the female head body, and a pressing block is connected to the outside of the third guide block. A locking block is connected to the left side of the pressing block, and a second spring is attached to the inside of the locking block. A green indicator plate is provided on the right side of the pressing block, and a red indicator plate is provided on the outside of the green indicator plate.

[0006] In one possible implementation, the first guide block is slidably connected to the female head body, and the first guide block is symmetrically arranged about the central axis of the male head body.

[0007] In one possible implementation, the pressing block is slidably connected to the third guide block, and the longitudinal section of the third guide block is a "T" shaped structure.

[0008] In one possible scenario, the locking block and the connecting block are engaged relative to each other, and the locking block is arranged symmetrically about the central axis of the female head body.

[0009] In one possible scenario, both the second waterproof ring and the first waterproof ring are engaged with the male connector body.

[0010] In one possible implementation, the shock-absorbing preload assembly includes a positioning block mounted on the outside of the slot, and a support frame connected to the left side of the positioning block, a third waterproof ring provided in the middle of the support frame, and a second guide block connected to the left side of the support frame. The positioning block and the support frame are engaged and connected, and the support frame is symmetrically arranged about the central axis of the female head body.

[0011] In one possible implementation, the second guide block is slidably connected to the support frame, and the third waterproof ring is engaged with the support frame.

[0012] In one possible implementation, the damping pretensioning assembly further includes a guide column installed inside the support frame, and a pretensioning plate is connected to the left side of the guide column, with a first spring provided on the inner side of the pretensioning plate; The pre-tightening plate and the guide post are slidably connected.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: The connector assembly with a waterproof sealing structure provides waterproof protection for the device by setting a main seal plus a secondary seal on the inner side of the male and female heads respectively. This ensures that the secondary seal structure still has strong sealing performance when the single sealing ring fails due to aging. Furthermore, the bipolar sealing structure can further improve the sealing and waterproof effect of the device, preventing water from breaking through the single sealing structure and directly entering the device when immersed. At the same time, an effective reverse pre-tightening structure is set inside the device, which ensures that the device still has effective stability when used in a vibration environment, resulting in better performance. The specific details are as follows. 1. The fourth waterproof ring, together with the female head body and the first waterproof ring, forms a complex three-layer waterproof mesh. This ensures that even if one of the four waterproof rings, the female head body, or the first waterproof ring loses its sealing effect due to aging, the other sealing structures still provide effective blocking. This prevents moisture from the outside of the device from directly entering the interior of the male and female heads through the waterproof mesh. By adopting this combined waterproof structure, the device maintains a strong waterproof effect even under high-pressure waterproof environments such as prolonged immersion, further improving the device's waterproof performance. 2. The first spring, in conjunction with the guide column, pushes the pre-tightening plate to move to the left inside the support frame, so that the device can always be kept taut during use, avoiding loosening of the connection due to vibration and improving the stability of the device. At the same time, the third waterproof ring set in the middle of the support frame provides a final waterproof barrier for the device inside. 3. By pressing the block in conjunction with the third guide block, the locking block is pushed from the outside to the inside of the female head body. This causes the locking block, which is displaced inward, to relax its locking limit on the connecting block, making it easier for the operator to pull the male head body and the female head body directly to the right to separate them. At the same time, the pressing block moves up and down, causing the green and red indicator plates to move synchronously. This allows the operator to observe the rebound status of the pressing block by observing the status of the red and green indicator plates, thus avoiding connection failure due to insufficient rebound.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1-5 The present invention provides the following technical solution: A connector assembly with a waterproof sealing structure includes: a male head body 1, a pin 2, a first waterproof ring 3, a second waterproof ring 4, a first guide block 5, a connecting block 6, a female head body 7, a slot 8, a positioning block 9, a support frame 10, a third waterproof ring 11, a second guide block 12, a guide post 13, a preload plate 14, a first spring 15, a third guide block 16, a pressing block 17, a locking block 18, a second spring 19, a green indicator plate 20, a red indicator plate 21, and a fourth waterproof ring 22. Specifically, such as Figure 1 , Figure 3 and Figure 5As shown, before using the device, the support frame 10 is installed inside the female head body 7. Due to the engaging connection structure between the positioning block 9 and the support frame 10, the positioning block 9 inside the female head body 7 can effectively limit and fix the support frame 10 placed inside the female head body 7. At the same time, the first guide block 5, which is set along the outside of the male head body 1, is installed on the right side of the male head body 1. At this time, the pin 2 inside the male head body 1 is inserted into the slot 8 opened inside the female head body 7, thereby completing the connection between the male head body 1 and the female head body 7. This allows the fourth waterproof ring 22, which is attached to the left side of the female head body 7, to be inserted into the male head body 1. Meanwhile, the second waterproof ring 4, which is attached to the right side of the male head body 1, is inserted into the interior of the female head body 7. The fourth waterproof ring 22, together with the female head body 7 and the first waterproof ring 3, forms a complex three-layer waterproof mesh. This ensures that even if one of the fourth waterproof ring 22, the female head body 7, or the first waterproof ring 3 loses its sealing effect due to aging, the other sealing structures still have an effective blocking structure, preventing moisture from the outside of the device from directly entering the interior of the male head body 1 and the female head body 7 through the waterproof mesh. By adopting this combined waterproof structure, the device still has a strong waterproof effect even under high-pressure waterproof environments such as long-term immersion, further improving the waterproof effect of the device. Simultaneously, during the installation process of the male connector body 1 and the female connector body 7, the support frame 10 installed inside the female connector body 7 inserts into the interior of the male connector body 1. Due to the sliding connection structure between the second guide block 12 and the support frame 10, the operator must strictly ensure that the second guide block 12 enters the designated groove during the connection of the male connector body 1 and the female connector body 7, further reducing the possibility of installation deviation. At the same time, the pre-tightening plate 14 set on the left side of the support frame 10 first contacts the inner surface of the male connector body 1. As the female connector body 7 continues to approach the male connector body 1, the pre-tightening plate 14 is squeezed and continuously retracts into the interior of the support frame 10. The first spring 15 is compressed, and due to the sliding connection structure between the pretension plate 14 and the guide post 13, the pretension plate 14 is guided and limited by the guide post 13 during its movement into the support frame 10, which prevents the pretension plate 14 from shifting position during its movement. At this time, the first spring 15 set inside the pretension plate 14 generates a reverse pretension force during the compression process, so that the device can always remain taut during use, preventing the device from becoming loose due to vibration, and improving the stability of the device. At the same time, the third waterproof ring 11 set in the middle of the support frame 10 also provides the device with a final waterproof barrier inside. Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, after the device is used, pressing the pressing block 17 inward causes it to move the locking block 18 connected to its left side inward, compressing the second spring 19. Due to the sliding connection between the third guide block 16 and the pressing block 17, the pressing block 17 and the locking block 18 are guided and limited by the third guide block 16 during their inward movement, preventing positional displacement. At this time, the inward-moving pressing block 17 causes the green indicator plate 20 and the red indicator plate 21 connected to its right side to move downward, bringing the red indicator plate 21 to the notch. Due to the engaging connection between the locking block 18 and the connecting block 6... The mechanism allows the locking block 18, which has shifted inward, to loosen its locking limit on the connecting block 6, making it easier for the operator to pull the male head body 1 and the female head body 7 directly to the right. At the same time, it loosens the pressing action on the pressing block 17, causing the compressed second spring 19 to push the pressing block 17 and the locking block 18 to move outward. At this time, the pressing block 17, which has reset outward, causes the green indicator plate 20 and the red indicator plate 21 to move outward again, so that the green indicator plate 20 returns to the notch. This allows the operator to observe the rebound state of the pressing block 17 by observing the state of the red indicator plate 21 and the green indicator plate 20, thus avoiding connection failure due to insufficient rebound.
