Description

Technical Field

[0001] The present invention relates to a design structure of a connector, and more specifically, to a right-angle bend rubber and plastic connector and its usage method. Background Art

[0002] A right-angle bend rubber and plastic connector is a connecting piece widely used in various electrical equipment and systems, mainly used to achieve reliable connection between wires and cables, especially in environments with limited space. Such connectors are usually made of rubber or plastic materials, have good insulation performance and environmental resistance, and can effectively prevent current leakage and short-circuit accidents. Their design allows the cable to turn at a 90-degree angle, thus saving installation space and facilitating wiring. However, their installation complexity is relatively high. Compared with straight connectors, the right-angle bend design increases the difficulty during the installation process. Especially when operating in a narrow space, more professional knowledge and technical support may be required to ensure correct installation.

[0003] The design principle of traditional right-angle bend rubber and plastic connectors is to directly screw the socket with loose wires into the bent housing. However, when the number of loose wires is large, the loose wires will overlap with each other, thus generating additional bending stress between them. This stress may not only cause the loose wires to fall off from the socket, but also increase the complexity and uncertainty of the assembly process, thereby affecting the reliability and stability of the final product. In addition, the falling off of the loose wires may also cause poor electrical connection, increasing the maintenance cost and failure rate. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a right-angle bend rubber and plastic connector and its usage method, which are convenient for leading out loose wires, have good overall reliability and overall performance of the product, and can adapt to more severe application environments after installation.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A right-angle bend rubber and plastic connector, including a housing, a right-angle channel for passing a cable is provided inside the housing, the right-angle channel includes a connection section and an outgoing section, a bending part is provided between the connection section and the outgoing section, an opening is provided at the rear end of the housing, and an outgoing channel is provided between the opening and the bending part. The outgoing channel is configured to lead out loose wires from the rear end of the housing. A sealing end cover is further provided inside the outgoing channel, the shape of the sealing end cover matches the shape of the outgoing channel, and the sealing end cover is configured to ensure the sealing performance at the opening.

[0006] The present invention is further configured such that: the sealing end cover includes a connecting body and a cover body, a plurality of sealing strips are arranged in the lead-out channel, a sealing groove matching the sealing strip is arranged on the connecting body, and the sealing groove and the sealing strip cooperate to form a seal for the lead-out channel. A sealing ring is further arranged at the bottom of the cover body.

[0007] The present invention is further configured such that: a threaded groove is arranged on the inner wall of the connecting section, and the threaded groove is used to allow the detachable connection between the housing and the socket.

[0008] Preferably, a rubber ring is further arranged at one end of the connecting section away from the bent part.

[0009] The present invention is further configured such that: a rubber sleeve is arranged on the inner walls of the lead-out section and the bent part, and the rubber sleeve is used to prevent the cable from being worn during the threading process.

[0010] The present invention is further configured such that: a bending cavity is arranged in the bent part, and the bending cavity has a guiding surface matching the connecting section and an outlet opening arranged on the guiding surface and matching the lead-out section.

[0011] The present application further provides a usage method of a right-angle bending rubber and plastic connector. The usage method includes the following steps: S11. Connect the housing to the socket through the threaded groove in the connecting section, and introduce all the loose wires in the socket into the right-angle channel;

[0012] S12. Divide the loose wires inside the right-angle channel. The staff classifies the loose wires according to the ports of the loose wires inside the right-angle channel. Set the classified diameter of the loose wires as D, and the actual diameter of the current loose wire as D1. If D1 < D, it is determined that the diameter of the current loose wire is smaller, and the loose wire is bent at the bent part and introduced into the lead-out section of the housing. On the contrary, if D1 > D, it is determined that the diameter of the current loose wire is larger, and the loose wire is directly led out from the opening at the rear end of the housing;

[0013] S13. After the loose wires are led out, bend the loose wires inside the opening outside the housing and introduce them back into the right-angle channel from the opening, and lead them out from the lead-out section of the right-angle channel;

[0014] S14. After the loose wires at the opening are led out, push the sealing end cover into the opening of the housing and press it tightly to form a seal for the opening of the housing;

[0015] S15. After the sealing end cover is installed, detect the installed housing. Place a humidity sensor inside the housing, and place the installed housing and the socket in water for a continuous T time period;

[0016] S16. After a time period T, the humidity sensor detects the humidity W inside the housing, and sets the minimum allowable humidity inside the housing as W0. If W < W0, it is determined that the sealing performance of the current housing meets the standard and the current connector is qualified. Otherwise, it is determined that the sealing state of the current connector is poor, and the opening of the connector is inspected. If the sealing end cover of the connector is installed incorrectly or there is a gap between the housing and the socket, it is determined that the reason for the poor sealing is an error in the installation process, and the housing is reinstalled and inspected. Otherwise, it is determined that the sealing performance of the current housing is poor after installation, and the housing is transferred to professional staff for maintenance.

[0017] Preferably, the described usage method further includes a processing method for the housing, including the following steps: S21. Fix the housing on a special fixture, and make the whole housing perpendicular to the horizontal plane of the special fixture.

[0018] S22. After the housing is installed, a first channel is processed through the housing. The first channel is the connection section and the opening of the housing.

[0019] S23. Process the connection section and the opening so that a thread groove for connecting with the socket is formed in the connection section, and a structure allowing the installation of the sealing end cover and forming a seal is formed in the opening.

[0020] S24. After the connection section and the opening are processed, the housing is re-clamped so that the channel processed in step S22 is parallel to the horizontal plane of the special fixture.

[0021] S25. After the housing is clamped, a second channel is processed on the housing so that the second channel communicates with the first channel.

[0022] S26. After the second channel is processed, a vulcanized layer adhesive is applied to the inner wall of the second channel, and a rubber sleeve is inserted into the second channel.

[0023] S27. After the rubber sleeve is installed, hot air at 110 °C is introduced into the second channel for a ventilation time of T1 so that the rubber sleeve is chemically bonded to the inner wall of the second channel.

[0024] By adopting the above technical solutions, the beneficial effects are as follows: 1. In this application, a split-type sealing end cover design is adopted, and a channel sealing strip and a sealing ring are used for multiple seals of the connection of the housing. At the same time, a relatively large opening is provided at the rear end of the housing, so that the scattered wires can extend naturally after entering the housing, preventing the scattered wires from being excessively bent inside the housing, thereby causing internal stress accumulation, reducing the risk of scattered wire detachment during the installation process. At the same time, after the housing is installed, it is sealed by the sealing ring and the sealing strip, improving the waterproof and dustproof capabilities of the connector, and meeting the usage requirements of scenarios with high waterproof and reliability requirements.

[0025] 2. Furthermore, the rear end of the shell is provided with an opening, and the opening can provide a larger bending space for the three wires during the wiring process. Specifically, in the process of leading out the scattered wires, if the rear end of the shell is not provided with an opening for leading out the scattered wires, the scattered wires need to be twisted directly at the bend of the channel, which makes it difficult to lead the wires. In addition, in the process of twisting the scattered wires, local stress concentration will occur due to space limitations, increasing the risk of the scattered wires falling off, thereby reducing the overall mechanical strength and reliability of the connector. By providing an opening at the rear end of the shell, the scattered wires can be conveniently sorted and guided inside the right-angle channel. Specifically, after the scattered wires enter the right-angle channel, they are led out from the rear end of the shell. The bent loose wires are then led back to the right-angle channel from the opening, avoiding bending of the loose wires inside the right-angle channel, reducing the difficulty of operation, and improving the efficiency of wiring. At the same time, the loose wires pass through the bottom through the larger opening below, making it easier for operators to install, reducing assembly errors caused by improper operation, and improving the qualified rate of products. In addition, since the loose wires no longer generate stress due to excessive bending, after the shell and the socket are connected, a stable connection can be maintained between the two, preventing the loose wires from falling off, and being able to maintain stable electrical contact with the socket for a long time, ensuring the stability of the electrical performance of the connector during long-term use and improving the electrical transmission efficiency.

[0026] 3. At the same time, the sealing end cover can form a seal with the opening of the shell, so as to ensure that the device has good dustproof and waterproof properties during use. Specifically, the sealing end cover and the opening form multiple seals of the sealing end cover and the opening through the sealing groove on the connector and the sealing strip in the lead-out channel, and the overall sealing effect is good. At the same time, by pressing the sealing end cover into the inside of the opening, the self-tightening seal of the device is achieved through a pushing action, which can prevent the seal from failing due to vibration or temperature changes. The effect of use is good and the service life is long. The end cover not only provides a sealing function, but also enhances the mechanical strength of the shell, protects the internal components of the shell from external impact and vibration, and extends the service life of the connector.

[0027] 4. Moreover, the above-mentioned connector is provided with a right-angle channel for wire bending in the housing, enabling it to be applied to various wiring scenarios. After the above-mentioned connector is manufactured, by connecting it to the socket part and conducting a sealing test on the connection body, unqualified processed products are prevented from entering the market. At the same time, the qualified products have good waterproof and dustproof properties and can meet complex and harsh environments, such as industrial automation, automotive manufacturing, aerospace and other fields. The scattered wires have high versatility and flexibility within the connector of the present application. At the same time, the present application is easy to assemble, has good overall sealing performance, and the maintenance of the cable can be conveniently achieved by disassembling and assembling the sealing end cover, significantly reducing the maintenance cost and downtime. Through the optimization of the connector structure, the present application not only solves the assembly problems existing in traditional right-angle bend rubber and plastic connectors, but also significantly improves the mechanical strength, electrical performance, protection performance and application scope of the connector, having important technical significance.

[0028] 5. Furthermore, during the processing of the present application, by respectively processing the first channel and the second channel in the housing, a connected section, an opening and an outlet section that communicate with each other are formed in the housing. And by respectively processing the connected section, the opening and the outlet section. Specifically, by processing threaded grooves in the connected section, it can be conveniently connected to the socket part. At the same time, by providing a rubber ring at one end of the connected section away from the bent part, after the connected section of the housing is connected to the socket part, the connection surface between the two is sealed by the rubber ring, and the waterproof effect is good. Moreover, a rubber sleeve is provided in the outlet section through a vulcanization reaction, so as to prevent damage to the scattered wires during the wire leading process, and the use effect is good. And several groups of sealing strips and sealing rings for sealing are provided at the opening, realizing the sealing of the opening end after installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] S14. After the loose wires at the opening are led out, push the sealing end cover into the opening of the housing and press it tightly to form a seal for the opening of the housing;

[0048] S16. After the T time period, the humidity sensor detects the humidity W inside the housing, and set the minimum allowable humidity inside the housing as W0. If W < W0, it is determined that the sealing performance of the current housing meets the standard and the current connector is qualified. Otherwise, it is determined that the sealing state of the current connector is poor, and the opening of the connector is inspected. If the sealing end cover of the connector is installed incorrectly or there is a gap between the housing and the socket, it is determined that the reason for the poor sealing is an error in the installation process, and the housing is reinstalled and detected again. Otherwise, it is determined that the sealing performance of the current housing is poor after installation, and the housing is transferred to professional staff for maintenance.

[0049] Preferably, the usage method further includes a processing method for the housing, comprising the following steps: S21. Fix the housing on a special fixture and make the whole housing perpendicular to the horizontal plane of the special fixture;

[0050] S22. After the housing is installed, a first channel is machined through the housing. The first channel is the connection section and the opening of the housing;

[0051] S23. Machine the connection section and the opening so that a threaded groove for connecting with a socket is formed in the connection section, and a structure allowing the installation of a sealing end cap and forming a seal is formed in the opening;

[0052] S24. After the connection section and the opening are machined, re-clamp the housing so that the channel machined in step S22 is parallel to the horizontal plane of the special fixture;

[0053] S25. After the housing is clamped, a second channel is machined on the housing so that the second channel communicates with the first channel;

[0054] S26. After the second channel is machined, apply a vulcanized layer adhesive to the inner wall of the second channel and insert a rubber sleeve into the second channel;

[0055] S27. After the rubber sleeve is installed, pass hot air at 110 °C into the second channel for a ventilation time of T1 to chemically bond the rubber sleeve to the inner wall of the second channel.

[0056] In this application, by adopting the split sealing end cap 3 design, and using the channel sealing strip 26 and the sealing ring to perform multiple seals on the connection of the housing 1. At the same time, by opening a larger opening 24 at the rear end of the housing 1, the scattered wires can naturally extend after entering the housing 1, preventing the scattered wires from being excessively bent inside the housing 1, thereby causing internal stress accumulation, reducing the risk of scattered wire detachment during installation. At the same time, after the housing 1 is installed, it is sealed by the sealing ring and the sealing strip 26, improving the waterproof and dustproof capabilities of the connector, and meeting the usage requirements of scenarios with high waterproof and reliability requirements.

[0057] Furthermore, the rear end of the shell 1 is provided with an opening 24, and the opening 24 can provide a larger bending space for the three wires during the wiring process. Specifically, in the process of leading out the scattered wires, if the rear end of the shell 1 is not provided with an opening 24 for leading out the scattered wires, the scattered wires need to be twisted directly at the bend of the channel, which makes it difficult to lead the wires, and in the process of twisting the scattered wires, local stress concentration will occur due to space limitations, increasing the risk of the scattered wires falling off, thereby reducing the overall mechanical strength and reliability of the connector. By providing an opening 24 at the rear end of the shell 1, the scattered wires can be conveniently sorted and guided inside the right-angle channel 2. Specifically, after the scattered wires enter the right-angle channel 2, they are pulled out from the rear of the shell 1.

At the same time, the loose wires pass through the bottom through the larger opening 24 below, making it easier for operators to install, reducing assembly errors caused by improper operation, and improving the qualified rate of products. In addition, since the loose wires no longer generate stress due to excessive bending, after the shell 1 and the socket are connected, a stable connection can be maintained between the two, preventing the loose wires from falling off, and being able to maintain stable electrical contact with the socket for a long time, ensuring the stability of the electrical performance of the connector during long-term use and improving the electrical transmission efficiency.

[0058] At the same time, the sealing end cover 3 can form a seal with the opening 24 of the shell 1, so as to ensure that the device has good dustproof and waterproof properties during use. Specifically, the sealing end cover 3 and the opening 24 form multiple seals of the sealing end cover 3 and the opening 24 through the sealing groove 33 on the connector 31 and the sealing strip 26 in the lead-out channel 25, and the overall sealing effect is good. At the same time, by pressing the sealing end cover 3 into the opening 24, the self-tightening seal of the device is achieved through a pushing action, which can prevent vibration or temperature changes from causing sealing failure.
