A type of conduit connector

Abstract

This utility model relates to the field of PVC conduit connection technology, and more specifically, to a conduit connector, including a main body and an elastic fixing cover. The main body includes a snap-fit ​​part and a socket part, which are connected. The outer wall of the snap-fit ​​part has a first slot, and the inner wall of the snap-fit ​​part has a second slot. The fixing cover is inserted into the end of the snap-fit ​​part away from the socket part. The outer wall of the fixing cover has a locking block, which engages with the second slot. The outer wall of the fixing cover abuts against the inner wall of the snap-fit ​​part. The main body is engaged with the switch box through the first slot. When the fixing cover is inserted into the snap-fit ​​part, the locking block engages with the second slot. Under the action of the fixing cover's own elasticity, the outer wall of the fixing cover abuts against the inner wall of the snap-fit ​​part, and the locking block engages with the second slot, squeezing the second slot to prevent deformation of the snap-fit ​​part. This increases the external force required to pull the main body out of the switch box, making the connection between the main body and the switch box more stable.

Description

Technical Field

[0001] This utility model relates to the field of PVC conduit connection technology, and more specifically, to a conduit connector. Background Technology

[0002] Common methods for connecting conduit connectors to switch boxes both domestically and internationally include: direct insertion, junction box connectors, transition connectors, and locknuts. Among these, the direct insertion method is widely used due to its convenience; however, it also has significant drawbacks, such as poor connection reliability, insufficient sealing, and stability issues under long-term use. Traditional conduit connector and junction box connection methods, due to their complex and time-consuming installation, can no longer meet the demands for reliability and efficiency.

[0003] Patent CN108591625A discloses an integrated snap-fit ​​PVC conduit connector, comprising a body, one end of which has a socket, and the other end has a snap-fit ​​with several notches. This connector allows installers to quickly install the conduit by simply opening a pre-drilled hole in the junction box, inserting the conduit into the socket, and then inserting the head of the connector into the pre-drilled hole. A "click" sound indicates installation is complete. This saves installation time, improves efficiency, and truly achieves one-click quick installation. However, in this solution, the connector and junction box are only connected by a snap-fit. When external force pulls the main body out of the junction box, the snap-fit ​​is prone to deformation, causing the main body to detach from the junction box, resulting in poor connection strength and stability. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of poor connection strength and stability in the existing technology, and to provide a conduit connector that can improve the connection strength between the conduit connector and the switch box while making the installation of the conduit connector more stable.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A conduit connector is provided, comprising a body and a resilient fixing cover. The body includes a snap-fit ​​portion and a socket portion for connecting with a conduit. The snap-fit ​​portion is connected to the socket portion. The outer wall of the snap-fit ​​portion has a first slot for engaging with a switch box, and the inner wall of the snap-fit ​​portion has a second slot. The fixing cover is inserted into the end of the snap-fit ​​portion away from the socket portion. The outer wall of the fixing cover has a locking block that engages with the second slot. The outer wall of the fixing cover abuts against the inner wall of the snap-fit ​​portion.

[0006] During installation, the main body of this utility model's conduit connector is inserted into a pre-drilled hole in the switch box. The main body is initially secured to the switch box via a first groove on the outer wall of the snap-fit ​​part. A flexible fixing cap is then inserted into the end of the snap-fit ​​part furthest from the receiving part. During insertion, the fixing cap contracts and deforms. The locking block on the outer wall of the fixing cap engages with the second groove on the inner wall of the snap-fit ​​part. Under the elastic force of the fixing cap itself, the outer wall of the fixing cap abuts against the inner wall of the snap-fit ​​part, and the locking block engages with and presses against the second groove, preventing deformation of the snap-fit ​​part. This increases the external force required to remove the main body from the switch box, making the connection between the main body and the switch box more stable. The elasticity of the fixing cap ensures a tight engagement between the locking block and the second groove, limiting the relative position of the fixing cap and the main body in the axial direction and preventing the fixing cap from detaching from the snap-fit ​​part. Finally, the conduit is connected to the receiving part of the main body, completing the installation.

[0007] Furthermore, the end of the fixing cover that inserts into the buckle portion is provided with several first elastic grooves. These first elastic grooves provide deformation space for the fixing cover. When the fixing cover is inserted into the buckle portion, the first elastic grooves are compressed and shrink, reducing the diameter of the insertion end of the fixing cover, thus facilitating smooth insertion. After the second slot aligns with the locking block, the fixing cover resets, and its outer wall abuts against the inner wall of the buckle portion, causing the locking block to engage tightly with the second slot, completing the installation of the fixing cover. The first elastic grooves reduce insertion resistance, making the installation of the fixing cover easier, simplifying the precision requirements for the fixing cover's processing, and reducing manufacturing costs.

[0008] Furthermore, the end of the latching part away from the socket part is provided with several second elastic grooves. These second elastic grooves provide deformation space for the latching part. When the main body is inserted into the switch box, the second elastic grooves contract and deform, causing the latching part to deform and its outer diameter to decrease, facilitating insertion into the pre-drilled hole in the switch box. When the first slot aligns with the pre-drilled hole in the switch box, the latching part resets, and the first slot engages with the pre-drilled hole in the switch box. When the fixing cover is inserted into the latching part, the latching part deforms, increasing its opening diameter, facilitating insertion of the fixing cover and reducing the assembly tolerance requirements between the fixing cover and the latching part. After the fixing cover is installed, the second elastic grooves reset, and the inner wall of the latching part fits tightly against the outer wall of the fixing cover, enhancing the overall structural strength, reducing gaps between components, and improving sealing. The second elastic grooves also disperse stress, reducing the risk of damage to the latching part due to excessive force during assembly.

[0009] Furthermore, a first guide slope is provided at the end of the snap-fit ​​portion away from the socket portion. The first guide slope guides the insertion direction of the fixing cover, reduces offset during insertion, makes it easier for the fixing cover to be inserted into the snap-fit ​​portion, and shortens the installation time.

[0010] Furthermore, the second slot is an annular groove, and the locking block is an annular protrusion. The annular structure ensures uniform circumferential contact between the locking block and the slot, resulting in a more reasonable stress distribution and extended service life.

[0011] Furthermore, it also includes a conduit fixing device, which is a ring-shaped structure. The conduit fixing device is sleeved on the outer wall of the main body and slidably connected to the main body. The inner wall of the conduit fixing device abuts against the outer wall of the socket. When connecting the conduit, the conduit fixing device is slid towards the snap-fit ​​part to leave space for conduit insertion. A conduit with an outer diameter slightly larger than the inner diameter of the socket is inserted into the socket. The conduit fixing device is then slid in the opposite direction, so that the inner wall of the conduit fixing device tightly presses against the outer wall of the socket, making the inner wall of the socket and the outer wall of the conduit fit tightly together. This increases the pressure and contact area between the socket and the conduit, thereby increasing the friction between the socket and the conduit and enhancing the connection strength between the conduit and the socket, thus completing the installation of the conduit. The ring-shaped structure forms a uniform circumferential pressure on the socket, preventing damage to the socket due to local pressure. It can adapt to the insertion requirements of conduits of different lengths and diameters within a certain range, improving the versatility of the connector.

[0012] Furthermore, the end of the socket portion away from the snap-fit ​​portion is provided with several third elastic grooves. These third elastic grooves at the end of the socket portion away from the snap-fit ​​portion give the socket portion a certain elastic deformation capability. When the conduit is inserted into the socket portion, the third elastic grooves are compressed and deformed, expanding and increasing the snap-fit ​​diameter of the socket portion. This facilitates smooth insertion of the conduit and allows the socket portion to adapt to conduits of different outer diameters within a certain range, improving the compatibility of the conduit joint.

[0013] Furthermore, the inner diameter of the socket gradually decreases from the opening of the socket to the connection with the snap-fit ​​part. The gradual decrease in the inner diameter of the socket from the opening to the connection with the snap-fit ​​part forms a tapered structure, guiding the conduit into the socket and allowing it to be inserted deeper. During insertion, as the insertion depth increases, the fit between the inner wall of the socket and the outer wall of the conduit gradually increases, and the pressure gradually increases. When the inner wall of the socket presses against the outer wall of the conduit, the conduit is initially fixed. The squeezing action of the tapered surface enhances the friction between the socket and the conduit, improving the connection strength and assisting in fixing the conduit.

[0014] Furthermore, it also includes a first limiting part and a second limiting part for limiting the sliding range of the conduit fixing device. The first limiting part is disposed on the outer wall of the snap-fit ​​part and located between the first snap-fit ​​groove and the socket part. The second limiting part is disposed on the outer wall of the socket part. The outer diameters of the first limiting part and the second limiting part are larger than the outer diameter of the conduit fixing device. The first limiting part restricts the conduit fixing device from sliding excessively towards the opening of the snap-fit ​​part, avoiding affecting the fit between the fixing cover and the snap-fit ​​part. The second limiting part prevents the conduit fixing device from falling off from the opening of the socket part, ensuring that the conduit fixing device always slides within its effective working range.

[0015] Furthermore, a second guide slope is provided on the side of the second limiting part away from the snap-fit ​​part. The second guide slope on the side of the second limiting part away from the snap-fit ​​part guides the conduit fixing device to smoothly fit into the socket part during installation, reducing resistance during installation and facilitating rapid construction.

[0016] Compared with the prior art, the beneficial effects of this utility model are: The conduit connector of this utility model: 1. Under the action of the elasticity of the fixing cover itself, the outer wall of the fixing cover abuts against the inner wall of the buckle part, and the buckle block abuts against the second buckle groove, preventing the buckle part from deforming, increasing the amount of external force required to pull the main body out of the switch box, and making the connection between the main body and the switch box more stable; 2. The first elastic groove provides deformation space for the fixing cover. When the fixing cover is inserted into the buckle part, the first elastic groove is squeezed and shrinks, reducing the diameter of the insertion end of the fixing cover, making it easier to smoothly insert the fixing cover into the buckle part and achieve quick installation; 3. After the conduit is inserted into the socket part, the conduit fixing device is slid towards the opening direction of the socket part, so that the inner wall of the conduit fixing device abuts against the outer wall of the socket part, making the inner wall of the socket part and the outer wall of the conduit part fit tightly, increasing the pressure and contact area between the socket part and the conduit, thereby increasing the friction between the socket part and the conduit part and enhancing the connection strength between the conduit and the socket part.

[0021] Example 1 like Figures 1 to 7The first embodiment of the conduit connector of this utility model is shown, including a main body and an elastic fixing cover 3. The main body includes a snap-fit ​​part 1 and a socket part 2 for connecting with the conduit. The snap-fit ​​part 1 is connected to the socket part 2. The outer wall of the snap-fit ​​part 1 is provided with a first slot 11 for engaging with a switch box 5, and the inner wall of the snap-fit ​​part 1 is provided with a second slot 12. The fixing cover 3 is inserted into the end of the snap-fit ​​part 1 away from the socket part 2. The outer wall of the fixing cover 3 is provided with a locking block 31 that engages with the second slot 12. The locking block 31 engages with the second slot 12, and the outer wall of the fixing cover 3 abuts against the inner wall of the snap-fit ​​part 1. In this embodiment, the outer wall of the fixing cover 3 is also provided with a third limiting part 33, which is an annular protrusion used to prevent the fixing cover 3 from being inserted too deeply into the main body, making it impossible to remove. Both the main body and the fixing cover 3 are made of PVC.

[0022] The conduit connector of this utility model, during installation, such as... Figure 3 and Figure 4 As shown, the snap-fit ​​part 1 of the main body is inserted into the reserved hole 51 of the switch box 5, and the main body is initially snapped and fixed to the switch box 5 through the first slot 11 on the outer wall of the snap-fit ​​part 1; as Figure 1 As shown, the elastic fixing cover 3 is inserted into the end of the snap-fit ​​part 1 away from the socket part 2. During the insertion process, the fixing cover 3 shrinks and deforms. After the snap block 31 on the outer wall of the fixing cover 3 engages with the second snap groove 12 on the inner wall of the snap-fit ​​part 1, the outer wall of the fixing cover 3 abuts against the inner wall of the snap-fit ​​part 1 under the action of the elastic force of the fixing cover 3 itself. The snap block 31 engages with the second snap groove 12 and squeezes the second snap groove 12 to prevent the snap-fit ​​part 1 from deforming. This increases the amount of external force required to pull the main body out of the switch box 5, making the connection between the main body and the switch box 5 more stable. The elastic force of the fixing cover 3 makes the snap block 31 and the second snap groove 12 tightly engage, restricting the relative position of the fixing cover 3 and the main body in the axial direction and preventing the fixing cover 3 from detaching from the snap-fit ​​part 1. The conduit is then connected to the socket part 2 of the main body to complete the installation.

[0023] like Figure 7 As shown, the fixed cover 3 has several first elastic grooves 32 at one end of the insertion buckle part 1. These first elastic grooves 32 provide deformation space for the fixed cover 3. When the fixed cover 3 is inserted into the buckle part 1, the first elastic grooves 32 are compressed and deform, reducing the diameter of the insertion end of the fixed cover 3, facilitating its smooth insertion into the buckle part 1. After the second slot 12 aligns with the locking block 31, the fixed cover 3 resets, causing the locking block 31 to engage tightly with the second slot 12, completing the installation of the fixed cover 3. The first elastic grooves 32 reduce insertion resistance, making the installation of the fixed cover 3 easier, simplifying the precision requirements for the fixed cover 3's processing, and reducing manufacturing costs. In this embodiment, three first elastic grooves 32 are provided, evenly distributed circumferentially.

[0024] The working principle of the conduit connector in this embodiment is as follows: During installation, the snap-fit ​​part 1 of the main body is inserted into the reserved hole 51 of the switch box 5. The main body is initially snapped and fixed to the switch box 5 through the first slot 11 on the outer wall of the snap-fit ​​part 1. The elastic fixing cover 3 is inserted into the end of the snap-fit ​​part 1 away from the socket part 2. The first elastic groove 32 is compressed and shrinks, reducing the diameter of the insertion end of the fixing cover 3 until the snap block 31 on the outer wall of the fixing cover 3 is aligned with the second slot 12 on the inner wall of the snap-fit ​​part 1. The fixing cover 3 is reset, causing the outer wall of the fixing cover 3 to abut against the inner wall of the snap-fit ​​part 1. The snap block 31 engages with the second slot 12 and presses the second slot 12. The conduit is then connected to the socket part 2 of the main body to complete the installation.

[0025] Example 2 This embodiment is the second embodiment of the conduit connector of this utility model. This embodiment is similar to the first embodiment, except that, as Figure 5 and Figure 6 As shown, the end of the latching part 1 away from the socket part 2 is provided with a plurality of second elastic grooves 13. In this embodiment, there are three second elastic grooves 13, which are evenly distributed circumferentially. The second elastic grooves 13 at the end of the latching part 1 away from the socket part 2 provide deformation space for the latching part 1. When the main body is inserted into the switch box 5, the second elastic grooves 13 shrink and deform, the latching part 1 deforms, and the outer diameter of the latching part 1 decreases, making it easier to insert the latching part 1 into the reserved hole 51 of the switch box 5. When the first slot 11 is aligned with the reserved hole 51 of the switch box 5, the latching part 1 resets, and the first slot 11 engages with the reserved hole 51 of the switch box 5. When the fixing cover 3 is inserted into the latching part 1, The second elastic groove 13 expands and deforms, causing the snap-fit ​​part 1 to deform and increasing the opening diameter of the snap-fit ​​part 1. This facilitates the insertion of the fixing cover 3 into the snap-fit ​​part 1 and reduces the assembly tolerance requirements between the fixing cover 3 and the snap-fit ​​part 1. After the fixing cover 3 is installed, the second elastic groove 13 returns to its original position, and the inner wall of the snap-fit ​​part 1 fits tightly against the outer wall of the fixing cover 3, enhancing the overall structural strength, reducing the gap between components, and improving the sealing performance. The second elastic groove 13 can also distribute stress, reducing the risk of the snap-fit ​​part 1 being damaged due to excessive force during assembly.

[0026] like Figure 6 As shown, the end of the snap-fit ​​part 1 away from the socket part 2 is provided with a first guide slope. The first guide slope guides the insertion direction of the fixing cover 3, reduces the offset during insertion, makes it easier for the fixing cover 3 to be inserted into the snap-fit ​​part 1, and shortens the installation time.

[0027] like Figure 5 As shown, the second slot 12 is an annular groove, and the locking block 31 is an annular protrusion. The annular structure ensures that the locking block 31 makes uniform contact with the slot circumferentially, resulting in a more reasonable stress distribution and extending service life. In this embodiment, the locking block 31 has a notch at the position where it passes through the second elastic groove 13.

[0028] The working principle of the conduit connector in this embodiment is as follows: During installation, the snap-fit ​​part 1 of the main body is inserted into the reserved hole 51 of the switch box 5. The second elastic groove 13 shrinks and deforms, the snap-fit ​​part 1 deforms, and the outer diameter of the snap-fit ​​part 1 shrinks until the first groove 11 is aligned with the reserved hole 51 of the switch box 5. The snap-fit ​​part 1 returns to its original position under its own elastic force, and the first groove 11 on the outer wall of the snap-fit ​​part 1 is initially snapped and fixed with the switch box 5. The elastic fixing cover 3 is inserted into the end of the snap-fit ​​part 1 away from the receiving part 2. The first guide slope guides the fixing cover 3 into the receiving part 2, and the first elastic groove 32 is squeezed by the snap-fit ​​part 1. The shrinkage deformation reduces the diameter of the insertion end of the fixing cover 3, and the second elastic groove 13 expands and deforms under the pressure of the fixing cover 3, increasing the diameter of the snap-fit ​​part 1. The deformation cooperation between the first elastic groove 32 and the second elastic groove 13 allows the fixing cover 3 to be inserted into the snap-fit ​​part 1 more smoothly. When the locking block 31 on the outer wall of the fixing cover 3 aligns with the second locking groove 12 on the inner wall of the snap-fit ​​part 1, the fixing cover 3 and the snap-fit ​​part 1 reset, causing the outer wall of the fixing cover 3 to abut against the inner wall of the snap-fit ​​part 1. The locking block 31 engages with the second locking groove 12 and presses the second locking groove 12. The conduit is then connected to the socket part 2 of the main body, completing the installation.

[0029] Example 3 This embodiment is the third embodiment of the conduit connector of this utility model. This embodiment is similar to embodiment two, except that, as Figure 2 and Figure 8 As shown, it also includes a conduit fixing device 4, which is a ring-shaped structure; as Figure 1 , Figure 3 and Figure 4 As shown, the conduit fixing device 4 is sleeved on the outer wall of the main body and slidably connected to the main body. The inner wall of the conduit fixing device 4 abuts against the outer wall of the socket 2. When connecting the conduit, the conduit fixing device 4 is slid towards the snap-fit ​​part 1 to leave space for conduit insertion. A conduit with an outer diameter slightly larger than the inner diameter of the socket 2 is inserted into the socket 2. The conduit fixing device 4 is then slid in the opposite direction, so that the inner wall of the conduit fixing device 4 tightly presses against the outer wall of the socket 2, making the inner wall of the socket 2 and the outer wall of the conduit fit tightly together. This increases the pressure and contact area between the socket 2 and the conduit, thereby increasing the friction between the socket 2 and the conduit, enhancing the connection strength between the conduit and the socket 2, and completing the installation of the conduit. The annular structure forms a uniform circumferential pressure on the socket 2, preventing damage to the socket 2 due to local pressure. It can adapt to the insertion requirements of conduits of different lengths and diameters within a certain range, improving the versatility of the connector. In this embodiment, the conduit fixing device 4 is a PVC structure.

[0030] like Figures 1 to 6As shown, the end of the socket 2 away from the snap-fit ​​part 1 is provided with several third elastic grooves 21. These third elastic grooves 21 at the end of the socket 2 away from the snap-fit ​​part 1 give the socket 2 a certain elastic deformation capability. When the conduit is inserted into the socket 2, the third elastic grooves 21 are compressed and deformed, expanding and increasing the snap-fit ​​diameter of the socket 2, facilitating smooth insertion of the conduit. This allows the socket 2 to adapt to conduits of different outer diameters within a certain range, improving the compatibility of the conduit joint. In this embodiment, three third elastic grooves 21 are provided, evenly distributed circumferentially.

[0031] like Figure 1 , Figure 4 and Figure 6 As shown, the inner diameter of the socket 2 gradually decreases from its opening to its connection with the snap-fit ​​part 1. This gradual reduction in diameter forms a tapered structure, guiding the conduit into the socket 2 and allowing it to penetrate deeper. As the insertion depth increases, the fit between the inner wall of the socket 2 and the outer wall of the conduit gradually increases, resulting in greater pressure. When the inner wall of the socket 2 presses against the outer wall of the conduit, initial fixation of the conduit is achieved. The tapered surface's squeezing action enhances the friction between the socket 2 and the conduit, increasing connection strength and aiding in conduit fixation. It also reduces the gap between the conduit and the socket 2, improving sealing. Furthermore, it guides the conduit's insertion direction, preventing misalignment during insertion.

[0032] like Figure 5 As shown, it also includes a first limiting part 14 and a second limiting part 22 for limiting the sliding range of the conduit fixing device 4. The first limiting part 14 is disposed on the outer wall of the snap-fit ​​part 1, and the second limiting part 22 is disposed on the outer wall of the socket part 2. The outer diameters of the first limiting part 14 and the second limiting part 22 are larger than the outer diameter of the conduit fixing device 4. The first limiting part 14 limits the conduit fixing device 4 from sliding excessively towards the opening of the snap-fit ​​part 1, so as to avoid affecting the fit between the fixing cover 3 and the snap-fit ​​part 1; the second limiting part 22 prevents the conduit fixing device 4 from falling off from the opening of the socket part 2, ensuring that the conduit fixing device 4 always slides within the effective working range.

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the second limiting part 22 has a second guide slope on the side away from the snap-fit ​​part 1. This second guide slope on the side of the second limiting part 22 away from the snap-fit ​​part 1 guides the conduit fixing device 4 to smoothly fit into the socket part 2 during installation, reducing resistance and jamming during installation. Simultaneously, the slope structure disperses stress when the fixing device contacts the limiting part, preventing component wear; simplifies the installation process of the conduit fixing device 4, improving assembly efficiency; reduces frictional damage between components, extending service life; and lowers the precision requirements for installers, facilitating rapid construction.

[0034] The working principle of the conduit connector in this embodiment is as follows: The first slot 11 of the snap-fit ​​part 1 is snapped into the reserved hole 51 of the switch box 5. The fixing cover 3 is inserted from the end of the snap-fit ​​part 1 away from the socket part 2, so that the snap-fit ​​block 31 is snapped into the second slot 12, completing the connection between the conduit connector and the switch box 5. The conduit fixing device 4 is inserted into the main body along the second guide slope, allowing the conduit fixing device 4 to slide between the first limiting part 14 and the second limiting part 22. The conduit fixing device 4 is slid towards the snap-fit ​​part 1, leaving space for conduit insertion. A conduit with an outer diameter slightly larger than the socket part 2 is then inserted into the main body. The conduit with an inner diameter of insert 2 is inserted into socket 2. The conduit moves along the conical inner wall of socket 2 deeper into socket 2 until the inner wall of socket 2 presses against the outer wall of conduit, thus achieving initial fixation of conduit. Conduit fixing device 4 slides in the opposite direction, so that the inner wall of conduit fixing device 4 tightly presses against the outer wall of socket 2, so that the inner wall of socket 2 and the outer wall of conduit are tightly fitted, increasing the pressure and contact area between socket 2 and conduit, thereby increasing the friction between socket 2 and conduit, enhancing the connection strength between conduit and socket 2, and completing the installation of conduit.

[0035] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
