Description

Technical Field

[0001] This utility model relates to the field of waterproof plug technology, specifically a novel waterproof plug with high connection strength. Background Technology

[0002] A waterproof socket is a type of outlet with waterproof properties, allowing for safe use in humid or underwater environments. It prevents water from entering the socket and causing safety hazards such as leakage and short circuits. Waterproof sockets not only have low contact resistance and more efficient current transmission, reducing energy loss, but their male and female plugs can also adapt to different devices and systems, offering wide applicability. Due to their stability, efficiency, wide applicability, and safety, male and female plugs hold an irreplaceable position in the field of electrical connections. However, because only one waterproof ring can be installed inside a waterproof socket, the waterproof effect is generally limited. Furthermore, the circular plug design allows for free rotation, but its stability is poor, making it prone to movement and causing the pins inside the plug to deform, potentially leading to a lack of power and limiting its lifespan.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202220962639.8, application date 2022-04-25) provides a waterproof plug, which consists of a male plug, a female plug, and a nut connecting the male and female plugs. A first waterproof ring is fitted onto the outer side of the external thread positioning ring on the male plug, and a second waterproof ring is fitted onto the outer side of the mating ring on the female plug. When the male and female plugs are connected by the nut, the two waterproof rings are used for waterproof sealing, resulting in better waterproof sealing performance. The mating ring is inserted into the external thread positioning ring, and the mating ring is inserted into the inner side of the external thread positioning ring. The female plug's socket is inserted into the male plug's socket, facilitating the insertion and positioning of the plug and female plug. The male plug's socket has a T-shaped groove, and the female plug's socket has a T-shaped protrusion that mates with the T-shaped groove. The use of a T-shaped interface makes the insertion more secure, preventing shaking and deformation, and extending the service life of the waterproof plug.

[0004] If the metal materials used for the plug pins and socket holes are not strong and tough enough, they are prone to deformation and breakage during insertion and removal. If inferior copper is used, its hardness and elasticity are poor, and the pins will bend after repeated insertion and removal, failing to make good contact with the socket and reducing the connection strength. During use, the above-mentioned device cannot improve the connection strength of the waterproof plug, resulting in unstable contact between the plug and socket, intermittent poor contact, which seriously affects the normal use of the equipment and significantly shortens the service life of the plug and socket. Utility Model Content

[0005] The purpose of this invention is to provide a new type of waterproof plug with high connection strength, in order to solve the problem mentioned in the background art that the connection strength of the waterproof plug cannot be improved, resulting in unstable contact between the plug and the socket, intermittent poor contact, which seriously affects the normal use of the equipment and significantly shortens the service life of the plug and the socket.

[0008] Preferably, a force-bearing plate is fixedly connected to one end of the sliding rod near the engaging block, and the sliding rods are symmetrically distributed about the center of the connecting plate, and a dustproof plate is fixedly connected to the surface of the rotating shaft.

[0009] Preferably, one end of the sliding rod near the engaging block is fixedly connected to a connecting spring, and the other end of the connecting spring is fixedly connected to the force-bearing plate.

[0010] Preferably, the lower end of the dustproof plate is fixedly connected to one end of a buffer spring, and the other end of the buffer spring is fixedly connected to the reinforcing cover.

[0011] Preferably, the sliding block has a sliding groove inside, and one end of a first spring is fixedly connected to the surface of the sliding groove, and the other end of the first spring is fixedly connected to a telescopic block.

[0012] Preferably, the telescopic blocks are symmetrically distributed about the center of the sliding block, and the lower end of the telescopic blocks is inclined, and the upper surface of the telescopic blocks is in contact with the lower surface of the locking block.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this new waterproof plug with high connection strength adopts a novel structural design, the specific details of which are as follows:

[0014] (1) The new type of waterproof plug with high connection strength, through the waterproof plug and the reinforcing cover, makes the connection tighter, reduces the situation of poor connection or disconnection caused by loosening, and at the same time ensures that the current is stably transmitted to the device through the plug, avoids the current fluctuation caused by the resistance change due to loose connection, and ensures that it can effectively resist moisture intrusion during long-term use.

[0015] Furthermore, the high-strength plugs ensure that the power supply and signal transmission of the equipment are not affected, guaranteeing the continuous and stable operation of the production line.

[0016] (2) This new type of waterproof plug with high connection strength effectively prevents dust from entering the connection part between the plug and the socket through the dustproof plate and buffer spring, ensuring that the metal contacts are always clean, maintaining good electrical connection, ensuring stable operation of the equipment, while extending the overall service life of the plug and socket, reducing the replacement frequency, and reducing the cost of use.

[0017] Furthermore, the buffer spring can effectively absorb impact force during insertion and removal, reduce the impact on internal metal parts, ensure a secure connection between the plug and socket, and prevent loosening.

[0018] (3) This new type of waterproof plug with high connection strength, through the setting of locking block and sliding block, makes it convenient for staff to maintain the waterproof plug, improves maintenance efficiency, and ensures that the reinforcing cover fits tightly and is accurately positioned with the waterproof plug body to achieve the best protection effect and ensure the stability of product quality.

Detailed Implementation

[0027] 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.

[0028] Example 1: By incorporating the anti-slip strip 2, reinforcing cover 8, and limiting block 13, the stability of the waterproof plug 1 during operation is improved, reducing the likelihood of poor connection or disconnection due to loosening. Figures 1-2 As shown: It includes a waterproof plug 1, an anti-slip strip 2 fixedly connected to the upper outer side of the waterproof plug 1, and the anti-slip strip 2 is distributed at equal angles on the outer side of the waterproof plug 1. A connecting plate 3 is fixedly connected to the outer side of the waterproof plug 1 near the anti-slip strip 2, and a reinforcing cover 8 is slidably connected to the upper surface of the connecting plate 3. A connecting block 9 is fixedly connected to the upper inner wall of the reinforcing cover 8, and a rotating shaft 18 is slidably connected inside the connecting block 9. A dustproof plate 10 is provided inside the reinforcing cover 8 through a reciprocating swing structure. A locking block 17 is fixedly connected to the upper front side of the connecting plate 3, and a limit block 13 is fixedly connected to the lower front side of the reinforcing cover 8. A sliding block 12 is connected inside the locking block 17 through a locking structure.

[0029] The operator aligns the reinforcing cover 8 with the upper surface of the connecting plate 3 via the outer connecting structure, and pushes the reinforcing cover 8 along the waterproof insert 1, causing the reinforcing cover 8 to slide on the upper surface of the connecting plate 3 (e.g., Figure 1 As shown), after the sliding block 12 inside the limiting block 13 engages with the engaging block 17, the installation of the reinforcing cover 8 is completed. At this time, the operator holds the external connector and, by increasing the friction through the anti-slip strip 2 on the outside of the waterproof plug 1, inserts the external connector more steadily into the waterproof plug 1. Figure 2 (As shown), and through the tight fit between the reinforcing cover 8 and the waterproof plug 1, the waterproof plug 1 is ensured to remain stable during the connection process, reducing poor connection caused by shaking or external force. At the same time, the adjusted dustproof plate 10 does not hinder the insertion of the external connector. After the external device is connected to the waterproof plug 1, the device begins to operate normally (as shown). Figure 2As shown, the reinforced cover 8 tightly wraps the connection area, making the connection tighter and reducing the possibility of poor connection or disconnection due to loosening. At the same time, it can ensure that the current is stably transmitted to the device through the plug, avoid current fluctuations caused by resistance changes due to loose connection, and ensure that it can effectively resist moisture intrusion during long-term use.

[0030] In Example 2, unlike Example 1, the locking block 17, sliding rod 5, and connecting plate 3 facilitate maintenance of the waterproof plug 1 by staff, improving repair efficiency. Figures 3-4 As shown: A fixing block 4 is fixedly connected to the front side of the connecting plate 3 near the locking block 17, and a sliding rod 5 is slidably connected inside the fixing block 4. A sliding block 12 is fixedly connected inside the limiting block 13. A force-bearing plate 6 is fixedly connected to the surface of the sliding rod 5 near the locking block 17, and the sliding rod 5 is symmetrically distributed about the center of the connecting plate 3. A dustproof plate 10 is fixedly connected to the surface of the rotating shaft 18. One end of the connecting spring 7 is fixedly connected to the surface of the sliding rod 5 near the locking block 17, and the other end of the connecting spring 7 is fixedly connected to the force-bearing plate 6.

[0031] When the operator performs maintenance on the waterproof insert 1, the operator presses the sliding rods 5 on both sides of the connecting plate 3, causing the sliding rods 5 to slide inside the fixed block 4 (e.g., Figure 3 As shown), and the connecting spring 7 on the surface of the fixed block 4 retracts towards the surface of the force plate 6, causing the force plate 6 to push and the telescopic block 16 to slide into the sliding block 12 (as shown). Figure 4 As shown, when the telescopic block 16 is fully inserted into the sliding block 12, the operator can pull the reinforcing cover 8 to remove it from the surface of the waterproof plug 1. This not only facilitates the maintenance of the waterproof plug 1, but also ensures that the reinforcing cover 8 fits tightly and is accurately positioned with the main body of the waterproof plug 1, so as to achieve the best protective effect and ensure the stability of product quality.

[0032] In Example 3, unlike Example 2, the use of a buffer spring 11, dustproof plate 10, and telescopic block 16 effectively prevents dust from entering the connection between the plug and socket, extending the service life of the waterproof plug 1. Figures 5-7 As shown: The lower end of the dustproof plate 10 is fixedly connected to one end of the buffer spring 11, and the other end of the buffer spring 11 is fixedly connected to the reinforcing cover 8. The sliding block 12 has a sliding groove 14 inside, and the surface of the sliding groove 14 is fixedly connected to one end of the first spring 15. The other end of the first spring 15 is fixedly connected to the telescopic block 16. The telescopic blocks 16 are symmetrically distributed about the center of the sliding block 12, and the lower end of the telescopic blocks 16 is inclined. The upper surface of the telescopic blocks 16 is in contact with the lower surface of the locking block 17.

[0033] When using the waterproof plug 1, the operator holds the waterproof plug 1 and connects it to the external connector. When the waterproof plug 1 contacts the external connector, the external connector pushes the dustproof plate 10 to rotate inside the reinforcing cover 8 around the pivot 18. Figure 6 As shown), the buffer spring 11 at the lower end of the dustproof plate 10 retracts towards the inner wall of the reinforcing cover 8, thus connecting the external connector to the waterproof plug 1. The reinforcing cover 8 surrounds the connection area between the external connector and the waterproof plug 1, providing additional lateral support to the connection by tightly wrapping the connection area. This prevents the connector from loosening or falling off due to external pulling or vibration, significantly enhancing the stability of the connection. (e.g.) Figure 5 and Figure 6 As shown), and when the sliding block 12 contacts the engaging block 17, the engaging block 17 pushes the telescopic block 16 to slide on the surface of the sliding groove 14, and causes the first spring 15 to retract towards the inner wall of the sliding block 12 (as shown). Figure 7 As shown, the sliding block 12 on the front side of the reinforcing cover 8 slides inside the locking block 17. After the external connector is connected to the waterproof plug 1, the first spring 15 pushes the upper surface of the telescopic block 16 to fit against the lower surface of the locking block 17, ensuring that the reinforcing cover 8 will not easily loosen or shift due to vibration or external pulling after connection. This greatly enhances the stability of the connection between the reinforcing cover 8 and the waterproof plug 1, ensuring that the waterproof plug 1 can maintain a good protective state in various complex environments.
