Description

Technical Field

[0001] The present application relates to the technical field of electrical connectors, and in particular to a 90-degree elbow waterproof connector that can be assembled quickly. Background Art

[0002] In the field of mechanical connectors, waterproof connectors are valued for their ability to ensure the normal operation of electrical equipment in humid or underwater environments. Waterproof connectors are widely used in various industrial equipment, marine detection equipment, and outdoor electronic equipment, which not only improves the reliability of the equipment, but also facilitates maintenance. In recent years, with the continuous improvement of industrial automation, the demand for waterproof connectors has continued to grow, and higher requirements have been placed on the connection speed and ease of operation of connectors. Rapid assembly and reliable waterproof performance have become the focus of market attention.

[0003] At present, the common designs for 90-degree elbow waterproof connectors mainly include threaded connection and snap-on connection. Although the threaded connection has good waterproof sealing, it requires the connector to be rotated during the assembly process, resulting in low assembly efficiency; the snap-on connection can improve assembly efficiency, but if the design is improper, it is difficult to ensure the waterproof effect. In addition, the snap-on connection may also become loose due to the aging of the elastic parts after long-term use, further affecting the stability of the connector.

[0004] However, it is difficult for existing snap-on connectors to achieve a good balance between assembly speed and waterproof performance. In particular, how to ensure structural stability and waterproof performance during rapid assembly has become a key issue that needs to be solved urgently.

[0005] Therefore, based on the above problems, the prior art needs to be improved. Summary of the invention

[0006] The purpose of the present application is to overcome the above-mentioned technical problems and provide a 90-degree elbow waterproof connector that can be quickly assembled.

[0007] The above-mentioned technical purpose of the present application is achieved through the following technical solutions: a 90-degree elbow waterproof connector that can be quickly assembled, comprising a first hollow shell and a second hollow shell, an insulator shell is arranged inside the first hollow shell, and a plurality of terminals are arranged inside the insulator shell; a card point is arranged on the first hollow shell, and a card slot is arranged on the second hollow shell, and the card slot includes a forward slot and a rotation avoidance slot, and the first hollow shell and the second hollow shell are initially connected and positioned by entering along the forward slot through the card point and then entering the rotation avoidance slot; a locking slot is arranged on the first hollow shell, and a locking buckle assembly is arranged on the second hollow shell, and the locking slot and the locking buckle assembly cooperate to limit the rotation of the first hollow shell relative to the second hollow shell after the first hollow shell is connected to the second hollow shell.

[0008] By adopting the above technical solution, by setting an insulator shell inside the first hollow shell and passing through a number of terminals, the stability and safety of the electrical connection are ensured. The card point on the first hollow shell cooperates with the card slot on the second hollow shell, wherein the forward slot and the rotation avoidance slot of the card slot enable the two shells to quickly achieve initial connection positioning, greatly improving the assembly efficiency. At the same time, the lock slot on the first hollow shell cooperates with the lock assembly on the second hollow shell, which can effectively limit the rotation of the first hollow shell relative to the second hollow shell after connection, ensuring the firmness and stability of the connection, thereby improving the reliability of the connector in various use environments, especially in occasions with high requirements for waterproof performance, the connector can play a better role.

[0009] Optionally, the locking assembly includes a mounting block arranged on the second hollow shell, the mounting block being provided with a mounting groove, a self-locking snap being embedded in the mounting groove, a latch being provided on the self-locking snap, and the latch being inserted into or away from the locking groove by the self-locking snap sliding in the mounting groove.

[0010] By adopting the above technical solution, the mounting block in the lock assembly is set on the second hollow shell, and the mounting groove of the mounting block provides a stable mounting position for the self-locking snap. The self-locking snap slides in the mounting groove, so that the pin can be easily inserted into or away from the lock slot. This design further improves the convenience of assembly of the connector. When connection is required, it is only necessary to slide the self-locking snap to insert the pin into the lock slot to quickly achieve a firm connection. When disassembly is required, the operation is also simple. This flexible locking method ensures that the connector can be quickly assembled during use, and can be reliably disassembled and maintained according to actual needs, thereby improving the practicality and applicability of the connector.

[0011] Optionally, the mounting block is hollow and has a mounting channel, a limiting spring sheet is provided at the channel opening at one end of the mounting channel away from the latch, a first elastic member is provided in the mounting channel, and a mounting pin is provided on the self-locking snap button, one end of the first elastic member abuts against the limiting spring sheet, and the other end is sleeved on the mounting pin and abuts against the self-locking snap button, so that the first elastic member is squeezed or released through the cooperation of the limiting spring sheet and the self-locking snap button.

[0012] By adopting the above technical solution, an installation channel is set in the hollow of the installation block, a limiting spring sheet is set at the entrance of the channel, and a first elastic member is set in the channel to cooperate with the self-locking snap. When the pin is inserted into the lock slot, the limiting spring sheet and the self-locking snap release the first elastic member. The first elastic member provides elastic force to make the connection of the pin in the lock slot more stable and reliable, which can effectively prevent accidental loosening and ensure the stable connection of the connector in various environments. When disassembly is required, the pin is moved by external force and the first elastic member is squeezed again, which makes the operation more convenient. This design not only improves the connection firmness of the connector, but also enhances its flexibility and convenience of use, making the connector more reliable and efficient in practical applications.

[0013] Optionally, a limiting piece is provided on the limiting spring sheet, a limiting slide groove is provided on the self-locking snap button, and the limiting piece is embedded in the limiting slide groove.

[0014] By adopting the above technical solution, the limiting piece on the limiting spring piece and the limiting slide groove on the self-locking snap are installed in mutual engagement, which can effectively limit the movement range of the self-locking snap during the use of the connector, ensuring that the self-locking snap slides more stably and accurately in the installation slide groove. This helps the pin to be accurately inserted into or away from the lock groove, improving the operational accuracy of connector assembly and disassembly. At the same time, this limiting structure also enhances the overall structural stability of the connector, allowing the connector to maintain a reliable connection state under various working conditions, further improving the performance and service life of the connector.

[0015] Optionally, a rotating shaft is provided on the first hollow shell, a plug-in snap is mounted on the rotating shaft, a second elastic member is provided on the first hollow shell, an end of the second elastic member away from the first hollow shell abuts against the plug-in snap, a buckle is provided on an end of the plug-in snap away from the second elastic member, a through hole is provided on the first hollow shell, and the buckle is passed through the through hole.

[0016] By adopting the above technical solution, the rotating shaft on the first hollow shell enables the plug-in snap to rotate flexibly, and under the action of the second elastic member, the snap at one end of the plug-in snap mounted on the rotating shaft can be stably inserted into the through hole on the first hollow shell. This structural design provides a convenient connection method during the assembly process of the connector. When it is necessary to connect with other components, the snap can be quickly engaged with the corresponding slot or interface to achieve quick connection and positioning. At the same time, the presence of the second elastic member enables the snap to have a certain elastic buffering effect during the connection process, and can adapt to connection objects of different sizes, thereby improving the versatility and compatibility of the connector. In addition, this design also facilitates the snap to be disconnected by pressing the plug-in snap when disassembly is required. The operation is simple and quick, which improves the convenience and efficiency of the connector.

[0017] Optionally, a groove is concavely provided on the insulator shell, a gasket is embedded in the groove, and a step structure is provided on the gasket for embedding and installing the second hollow shell.

[0018] By adopting the above technical solution, the groove provides a stable installation position for the gasket, ensuring that the gasket will not be easily displaced during use. The step structure on the gasket can be installed in an interlocking manner with the second hollow shell. On the one hand, it enhances the tightness of the connection between the first hollow shell and the second hollow shell, improves the waterproof performance, effectively prevents impurities such as moisture and dust from entering the connector, and protects the internal electrical components. On the other hand, the step structure makes the connection between the two hollow shells more accurate and stable, reduces problems such as looseness and poor contact caused by loose connections, and improves the reliability and service life of the connector. At the same time, this design also facilitates the assembly of the connector, making the assembly process more efficient and accurate.

[0019] Optionally, a first fixing groove is provided in a concave ring at one end of the insulator shell away from the second hollow shell, and a first waterproof ring is provided inside the first fixing groove.

[0020] By adopting the above technical solution, the first fixing groove provides a stable installation position for the first waterproof ring, so that the first waterproof ring will not be easily displaced or fall off during use. The first waterproof ring forms a reliable waterproof defense line here. When the external device is inserted into the first hollow shell and connected to the terminal, it can effectively prevent external moisture from invading the inside of the connector from this end, greatly improving the overall waterproof performance of the connector. This design enables the connector to still work stably in complex environments such as humidity and water, expanding its application scenarios. Good waterproof performance protects the internal electrical components from damage due to moisture intrusion, thereby extending the service life of the connector and improving its reliability and stability.

[0021] Optionally, a second fixing groove is provided in a concave ring at one end of the insulator shell close to the second hollow shell, and a second waterproof ring is provided inside the second fixing groove.

[0022] By adopting the above technical solution, the second fixing groove provides a stable installation position for the second waterproof ring, ensuring that it will not be easily changed during use. The second waterproof ring forms another solid waterproof barrier here, and cooperates with the first waterproof ring at the other end to effectively prevent moisture from penetrating into the connector from two directions. This greatly enhances the waterproof performance of the connector, enabling it to operate reliably in various harsh and humid environments and even underwater environments. Good waterproof protection extends the service life of internal electrical components and reduces the risk of failure caused by moisture intrusion. At the same time, this double waterproof design also improves the overall quality and reliability of the connector, making it more widely and reassuringly used in many fields.

[0023] Optionally, a third fixing groove is provided on the insulator shell, and a third waterproof ring is provided in the third fixing groove.

[0024] By adopting the above technical solution, the third fixing groove provides a stable installation position for the third waterproof ring, and the third waterproof ring is located at the installation position of the first hollow shell and the insulator shell, providing additional waterproof protection for the connection part. It effectively prevents moisture from penetrating from the connection between the first hollow shell and the insulator shell, further enhancing the overall waterproof performance of the connector. This multiple waterproof design ensures that the connector can maintain good sealing in various complex environments and prevents damage to internal electrical components due to moisture intrusion. At the same time, the presence of the third waterproof ring also improves the structural stability of the connector, making the connection between the first hollow shell and the insulator shell tighter and more reliable, reducing potential problems caused by looseness or gaps. This design improves the reliability and durability of the connector, enabling it to perform excellent performance in different application scenarios.

[0025] Optionally, an engaging groove is concavely provided in the bottom of the rotation avoidance groove for engaging and installing the card point, and a guide surface is provided in the rotation avoidance groove 62 .

[0026] By adopting the above technical solution, the guide surface in the avoidance groove is rotated to guide the card point to be inserted into the insertion groove. The insertion groove provides a clear and stable installation position for the card point, which enhances the stability of the connection between the first hollow shell and the second hollow shell, can effectively resist external impact and vibration, prevent accidental separation, and ensure stable connection in various working environments. At the same time, the accuracy of connection positioning is improved, which helps to improve assembly efficiency, reduce repeated operations, and ensure connector performance and quality. In addition, the gap between the shells is further reduced, the waterproof performance is enhanced, and impurities such as moisture and dust are prevented from entering the internal protection electrical components to extend the service life. On the whole, the connector connection structure is made more complex and reliable, the maintenance cost and failure rate are reduced, and the overall reliability of the connector is improved.

[0027] In summary, this application has at least the following beneficial effects: 1. The first hollow shell and the second hollow shell are quickly positioned and connected by the card point on the first hollow shell and the card slot on the second hollow shell, thereby improving the assembly speed of the connector; 2. The lock groove cooperates with the lock assembly to limit the rotation of the first hollow shell relative to the second hollow shell after the initial connection, thereby improving the structural stability and anti-loosening ability of the connector; 3. The multi-layer waterproof ring design inside the insulator shell ensures the waterproof sealing of the connector in humid or underwater environments, and improves the reliability of electrical equipment operation.

[0030] The present application is further described in detail below in conjunction with the accompanying drawings.

[0031] In this embodiment, refer to Figure 1-5 A 90-degree elbow waterproof connector that can be quickly assembled includes a first hollow shell 1 and a second hollow shell, wherein an insulator shell 3 is arranged inside the first hollow shell 1, and a plurality of terminals 4 are inserted into the insulator shell 3; a card point 5 is arranged on the first hollow shell 1, and a card slot 6 is arranged on the second hollow shell 2, and the card slot 6 includes a forward slot 61 and a rotation avoidance slot 62, and the card point 5 enters along the forward slot 61 and then enters the rotation avoidance slot 62 to achieve the initial connection and positioning of the first hollow shell 1 and the second hollow shell 2; a locking slot 7 is arranged on the first hollow shell 1, and a locking assembly 8 is arranged on the second hollow shell 2, and the locking slot 7 and the locking assembly 8 cooperate to limit the rotation of the first hollow shell 1 relative to the second hollow shell 2 after the first hollow shell 1 is connected to the second hollow shell 2. Through this scheme, not only the assembly speed is accelerated, but also the good waterproof performance of the connector is ensured.

[0032] Specifically, the first hollow shell 1 is made of plastic or metal material, and the first hollow shell 1 is hollow and used to accommodate the insulator shell 3, and three terminals 4 are inserted into the insulator shell 3. The insulator shell 3 can be made of a material with high insulation performance, such as epoxy resin or polytetrafluoroethylene. A plurality of terminal 4 fixing holes are provided in the insulator shell 3 for fixing the terminals 4. The card point 5 is arranged on the inner side wall of the first hollow shell 1, and can specifically be a block structure protruding outward, which is used to cooperate with the card slot 6 on the second hollow shell 2. The card point 5 material can be selected from the same material as the first hollow shell 1 or a high-hardness metal material, and the card point 5 is integrally formed with the first hollow shell 1. There are a plurality of card points 5, and a plurality of card slots 6 are provided corresponding to the card points 5. Preferably, there are three card points 5 and three card slots 6, respectively, and the three card points 5 are evenly spaced.

[0033] The second hollow shell 2 is also made of high-strength material. The card slot 6 is located on the outer side wall of the second hollow shell 2. The card slot 6 is subdivided into a forward slot 61 and a rotation avoidance slot 62. The forward slot 61 is the initial path for the card point 5 to enter. Its width is equal to or slightly larger than the maximum diameter of the card point 5, so that the card point 5 can enter smoothly; the rotation avoidance slot 62 is located on one side of the forward slot 61 and is used to locate the final card point 5. The specific structures of the forward slot 61 and the rotation avoidance slot 62 can be appropriately adjusted according to the design of the card point 5. It is preferred that the setting directions of the forward slot 61 and the rotation avoidance slot 62 are set at 90 degrees.

[0034] Through this structural design, when the first hollow shell 1 and the second hollow shell 2 are initially connected, the card point 5 enters along the forward groove 61. When the card point 5 moves to the end of the forward groove 61, the first hollow shell is rotated to move the card point 5 into the rotation avoidance groove 62, so that the first hollow shell cannot be separated from the second hollow shell along the setting direction of the forward groove 61, thereby achieving initial connection positioning.

[0035] A lock slot 7 is provided at a corresponding position on the outer side wall of the first hollow shell 1 to match the lock assembly 8. The lock slot 7 can adopt different shapes according to actual design requirements, such as rectangular, spherical or elliptical, etc. The design of the lock slot 7 can adapt to lock assemblies 8 of different shapes and sizes.

[0036] Reference Figure 2 The lock assembly 8 includes a mounting block 81 fixed on the second hollow shell 2. The mounting block 81 can adopt different shapes according to the design of the second hollow shell 2, such as rectangular, elliptical or cylindrical. The material of the mounting block 81 can be selected from high-strength engineering plastics or metal materials. A mounting slide 9 is provided on the mounting block 81. The mounting slide 9 is used to assemble the self-locking snap 82. The slide can be a straight groove or a groove with a curvature. The specific shape can be flexibly adjusted according to the design of the self-locking snap 82. The self-locking snap 82 is embedded in the mounting slide 9. The self-locking snap 82 is made of a high-toughness material, such as polyamide or thermoplastic polyester. A latch 83 is provided on the self-locking snap 82. The self-locking snap 82 slides in the mounting slide 9, so that the latch 83 is plugged into or away from the lock slot 7 to achieve the final locking function.

[0037] The combination logic and combination effect of all the secondary features that make up the lock assembly 8 are specifically described. The mounting block 81, the self-locking snap 82 and the latch 83 in the lock assembly 8 cooperate with each other to achieve the safe locking of the connector. The mounting block 81 fixes the self-locking snap 82 through the mounting slide 9 thereon, so that the self-locking snap 82 can slide freely in the slide; the latch 83 follows the movement of the self-locking snap 82 by being fixed on the self-locking snap 82. When the self-locking snap 82 slides to the position of the lock slot 7, the latch 83 is inserted into the lock slot 7, so that the card point 5 cannot move in the rotation avoidance groove 62, ensuring that the connection between the first hollow shell 1 and the second hollow shell 2 is firm and cannot be arbitrarily separated.

[0038] The implementation principle of this embodiment is as follows: this embodiment realizes rapid assembly by setting the card point 5 and the card slot 6, and realizes fixed locking by the lock assembly 8. By designing the positions of the card point 5 and the card slot 6 at specific positions, and reasonably arranging the lock slot 7 and the lock assembly 8, the stability and reliability of the connector during the assembly process are ensured. In addition, through reasonable material selection and structural design, the service life and performance of the connector are further improved, and the problems of low assembly efficiency and poor waterproof performance existing in the prior art are solved.

[0039] Example 2 Reference Figure 3-4 The difference between this embodiment and the above embodiment is that the specific implementation method of the lock assembly 8 is further optimized. Specifically, the installation block 81 is hollow with an installation channel 10, and a limiting spring sheet 84 is provided at the end of the installation channel 10 away from the latch 83, preferably a metal spring sheet, and a first elastic member 85 is provided in the installation channel 10, preferably a spring, and a mounting pin 11 is provided on the self-locking snap 82. One end of the first elastic member 85 abuts against the limiting spring sheet 84, and the other end is sleeved on the mounting pin 11 and abuts against the self-locking snap 82. The limiting spring sheet 84 and the self-locking snap 82 cooperate to squeeze or release the first elastic member 85. When the latch 83 is inserted into the lock slot 7, the limiting spring sheet 84 and the mounting pin 11 release the first elastic member 85. The first elastic member 85 provides elastic force to make the connection of the latch 83 in the lock slot 7 more stable and reliable, which can effectively prevent accidental loosening and ensure the stable connection of the connector in various environments. When disassembly is required, the latch 83 is moved by external force to re-squeeze the first elastic member 85, so that in the absence of external force, the latch 83 can rebound and fit into the lock slot 7 to complete the locking, which makes the operation more convenient.

[0040] Reference Figure 5The limiting spring piece 84 is provided with a limiting member 86, and the self-locking snap 82 is provided with a limiting slide groove 12, and the limiting member 86 is embedded in the limiting slide groove 12. The limiting member 86 on the limiting spring piece 84 and the limiting slide groove 12 on the self-locking snap 82 are embedded in each other, and during the use of the connector, the movement range of the self-locking snap 82 can be effectively limited to prevent the self-locking snap 82 from being separated from the mounting block 81, and at the same time ensure that the self-locking snap 82 slides in the mounting slide groove 9 more stably and accurately.

[0041] Example 3 Reference Figure 2 and Figure 4 , the difference between this embodiment and the above embodiment is that: a rotating shaft 13 is provided on the first hollow shell 1, a plug-in snap button 14 is mounted on the rotating shaft 13, a second elastic member 15 is provided on the first hollow shell 1, an end of the second elastic member 15 away from the first hollow shell 1 abuts against the plug-in snap button 14, a buckle 16 is provided on the end of the plug-in snap button 14 away from the second elastic member 15, a through hole 17 is provided on the first hollow shell 1, and the buckle 16 is passed through the through hole 17. Specifically, the second elastic member 15 is installed at a suitable position on the first hollow shell 1, and the second elastic member 15 is preferably a spring. One end of the second elastic member 15 should be firmly connected to the first hollow shell 1 to ensure that it will not shift during use. The end of the second elastic member 15 away from the first hollow shell 1 tightly abuts against the plug-in snap button 14 to provide elastic support force for the plug-in snap button 14. A buckle 16 is provided at the end of the plug-in snap button 14 away from the second elastic member 15. The design of the buckle 16 should meet the connection requirements and have a certain strength and a suitable shape so that it can be buckled with the corresponding connection part. A through hole 17 is set on the first hollow shell 1 at a position corresponding to the buckle 16. The size of the through hole 17 should be slightly larger than the buckle 16, so that the buckle 16 can be smoothly inserted into the through hole 17, and can be flexibly extended and retracted under the action of the elastic member to achieve connection and separation with the external device.

[0042] Example 4 Reference Figure 2, the difference between this embodiment and the above embodiment is that: a groove 18 is provided in the insulator housing 3, a gasket 19 is installed in the groove 18, and a step structure is provided on the gasket 19 for installing the second hollow housing 2. Specifically, during the design and manufacturing process of the insulator housing 3, the groove 18 is formed in the insulated part by a precise processing technology. The size and shape of the groove 18 should be designed according to the size and shape of the gasket 19 to ensure that the gasket 19 can be tightly fitted in the groove 18 without loosening or falling off. The material of the gasket 19 should have certain elasticity and wear resistance to meet the use requirements of the connector. The gasket 19 is installed in the groove 18 of the insulator housing 3 to ensure that the gasket 19 and the groove 18 are tightly and seamlessly fitted. A step structure is provided on the side of the gasket 19 away from the groove 18. The size and shape of the step structure should be designed according to the connection part of the second hollow housing 2 so that the second hollow housing 2 can be accurately fitted on the step structure of the gasket 19. When installing the second hollow housing 2, align it with the step structure of the gasket 19, gently press it or use other appropriate methods to make it tightly combined with the gasket 19 to achieve a stable connection. Such a design can improve the accuracy and stability of the connection, and also help to enhance the sealing and waterproof performance of the connector.

[0043] Example 5 Reference Figure 2 , the difference between this embodiment and the above embodiment is that: the waterproof structure design on the insulator housing 3 is described in detail, including the specific implementation methods of the first waterproof ring 21, the second waterproof ring 23 and the third waterproof ring 25. The insulator housing 3 is provided with a first fixed groove 20 in the concave ring at one end away from the second hollow housing 2, and a first waterproof ring 21 is arranged inside the first fixed groove 20. Preferably, the first fixed groove 20 is arranged at the installation connection between the external device and the insulator housing 3 to prevent water or other substances from entering the connector at the interface where the first hollow housing 1 is plugged into the external device. The insulator housing 3 is provided with a second fixed groove 22 in the concave ring at one end close to the second hollow housing 2, and a second waterproof ring 23 is arranged inside the second fixed groove 22. Preferably, the second fixed groove 22 is arranged at the installation connection between the second hollow housing 2 and the insulator housing 3 to prevent water or other substances from entering the connector. A third fixing groove 24 is provided on the insulator shell 3, and a third waterproof ring 25 is provided in the third fixing groove 24. The third fixing groove 24 is provided between the first fixing groove 20 and the second fixing groove 22, and is preferably provided at the installation connection between the first hollow shell 1 and the insulator shell 3, for supplementing the waterproof function. When the first waterproof ring 21 or the second waterproof ring 23 fails, it can still prevent water or other substances from entering the interior of the connector.

[0044] The implementation principle of this embodiment is: adopting a multi-layer waterproof ring structure and using different waterproof rings in combination to make the connector more stable and reliable in overall waterproof capability.

[0045] Embodiment 6, Reference Figure 3 The difference between this embodiment and the above embodiment is that: the bottom of the rotation avoidance groove 62 is concavely provided with an engaging groove 26 for engaging and installing the card point 5, and a guide surface is provided in the rotation avoidance groove 62. Preferably, the engaging groove 26 is provided at the end of the rotation avoidance groove 62 away from the forward groove 61. When the card point 5 enters the rotation avoidance groove 62, it is guided by the guide surface so that the card point 5 is engaged and installed into the engaging groove 26. The engaging groove 26 provides a clear and stable installation position for the card point 5, enhances the stability of the connection between the first hollow shell 1 and the second hollow shell 2, can effectively resist external impact and vibration, prevent accidental separation, and ensure stable connection under various working environments.
