Description

Technical Field

[0001] This application relates to the technical field of power connectors, and particularly to a male-female pluggable industrial connector. Background Art

[0002] In industrial applications, power connectors are key components for power transmission between different modules inside equipment. With the development of technology, more and more equipment needs to work under harsh conditions, such as immersion in water, high temperature, high humidity, and high-frequency vibration environments. However, conventional connectors on the market currently cannot meet the power transmission requirements under these harsh conditions, and there are problems such as insufficient structural strength, poor sealing performance, and susceptibility to external environmental interference.

[0003] Currently, conventional connectors are not specifically designed to consider environmental factors such as immersion in water, high temperature, high humidity, and high-frequency vibration. Therefore, when used under these conditions, problems such as unstable power transmission and damage to the connector structure are likely to occur. This not only affects the normal operation of the equipment but may also pose safety hazards.

[0004] Therefore, based on the above problems, the existing technology needs to be improved. Summary of the Utility Model

[0005] The purpose of this application is to strengthen the structural strength and sealing effect through tail dispensing, and to improve the sealing and shock absorption performance by adding a waterproof ring at the position of the insertion slot, so as to achieve stable power transmission under harsh conditions (immersion in water, high temperature, high humidity, high-frequency vibration).

[0006] The above technical purpose of this application is achieved through the following technical solutions: A male-female pluggable industrial connector includes a male connector and a female connector. The male connector includes a plastic shell. A plurality of first installation channels are hollowly provided in the plastic shell. Female terminals are installed in the first installation channels. One end of the plastic shell close to the female connector is recessed to form an insertion slot. A first installation slot is provided at one end of the plastic shell away from the female connector. A first dispensing layer is provided in the first installation slot. The female connector includes a housing. A glue core is provided inside the housing. A plurality of second installation channels are provided on the glue core. Male terminals are installed in the second installation channels. A second installation slot is formed by surrounding the side of the housing and the glue core away from the male connector. A second dispensing layer is provided in the second installation slot.

[0007] By adopting the above technical solutions, the precise installation of the male terminal and the female terminal in the first installation channel and the second installation channel ensures good contact, reduces resistance and energy loss, and makes the power transmission more stable and efficient. The setting of the first glue layer and the second glue layer enhances the structural stability and sealing performance, and at the same time reduces the connection looseness caused by vibration or temperature change, further ensuring the stability of power transmission. The plastic shell and the outer shell provide good physical protection for the internal terminals and glue cores, preventing external physical impacts and foreign object intrusion. The design of the insertion slot and the possible waterproof ring effectively prevent impurities such as moisture and dust from entering the connector, ensuring normal operation in harsh environments such as humidity and dust. The comprehensive protection and stability performance enable it to work normally under harsh conditions such as immersion in water, high temperature, high humidity, and high-frequency vibration.

[0008] Optionally, a waterproof ring is provided in the insertion slot.

[0009] By adopting the above technical solutions, the setting of the waterproof ring can effectively block moisture from entering the connector, ensuring that the connector can still work normally in a humid or even water-immersed environment, and guaranteeing the stability and safety of power transmission. The waterproof ring enables the connector to be widely used in various harsh humid environments without being affected by moisture, expanding its scope of use and application scenarios. The waterproof ring prevents moisture from eroding the internal components, reducing corrosion and damage caused by water ingress, and thus extending the overall service life of the connector.

[0010] Optionally, the insertion slot is provided with convex ribs, and the outer shell is recessed with grooves, and the convex ribs are fitted and embedded in the grooves.

[0011] By adopting the above technical solutions, the cooperation between the convex ribs and the grooves can ensure the precise alignment of the male connector and the female connector during insertion, avoiding deviation, thereby improving the connection stability and reducing problems such as poor contact or connection looseness caused by inaccurate insertion. When subjected to high-frequency vibration, the mutual engagement of the convex ribs and the grooves can effectively limit the relative displacement between the male and female connectors, preventing connection looseness or disconnection caused by vibration and ensuring the continuity of power transmission. This cooperation structure can increase the sealing performance of the connector, reduce the possibility of dust, impurities, etc. entering the connector, further protecting the internal terminals and glue cores, and improving the reliability and service life of the connector.

[0012] Optionally, a plurality of convex ribs are provided.

[0013] By adopting the above technical solutions, the cooperation of multiple convex ribs and grooves can provide more uniform support and fixation, making the connection between the male and female connectors more stable, and reducing the risk of loosening or displacement in complex working environments. The multiple convex ribs share the external force received during connection, making the stress distribution more uniform, reducing structural damage caused by excessive local stress, and improving the overall durability of the connector. More convex ribs can better fill the gaps at the insertion part, further enhancing the sealing performance of the connector, effectively preventing the intrusion of external substances, and ensuring the reliability of the internal electrical connection.

[0014] Optionally, an installation part is provided on the plastic shell, an installation plate is provided on the outer shell, and installation holes are provided on the installation plate corresponding to the installation part.

[0015] By adopting the above technical solutions, the cooperation of the installation part, the installation plate and the installation holes enables the connector to be conveniently, quickly and firmly installed at a specified position on the device, improving the installation efficiency and reducing the cumbersome operations during the installation process. It ensures that the connector will not be displaced or detached due to external force or vibration during use, guaranteeing the stability and reliability of power transmission. The installation position and angle of the connector can be flexibly adjusted according to the space and wiring requirements inside the device to adapt to different installation environments and device structures.

[0016] Optionally, a limiting groove is recessed on the rubber core, and a limiting part is provided on the outer shell.

[0017] By adopting the above technical solutions, the cooperation of the limiting groove and the limiting part can ensure the accurate installation position of the rubber core in the outer shell, avoiding the deviation or misalignment of the rubber core installation, thereby ensuring the rationality and stability of the internal structure of the connector. It can effectively limit the movement of the rubber core in the outer shell, prevent the rubber core from being displaced due to vibration or external force during use, and improve the overall structural strength and stability of the connector. During the assembly process, the rubber core can be quickly and accurately installed into the outer shell through the guidance of the limiting groove and the limiting part, improving the production efficiency and reducing the probability of assembly errors.

[0018] Optionally, an installation calibration part is provided on the rubber core, and an installation calibration groove is recessed in the outer shell.

[0019] By adopting the above technical solution, the cooperation between the installation calibration part and the installation calibration groove provides clear guidance and positioning for the installation process, enabling the rubber core to be quickly and accurately installed in the correct position within the housing, greatly improving the installation efficiency and accuracy, and reducing the possibility of installation errors. It ensures that the relative positions of the rubber core and the housing are consistent during each assembly, thus guaranteeing the stability of the performance and quality of the connector and reducing connection problems or performance degradation caused by assembly deviations. This clear calibration structure is conducive to realizing automated assembly in large-scale production, improving production consistency and speed, and reducing production costs. Through precise calibration and installation, the combination between the rubber core and the housing becomes tighter and more coordinated, enhancing the overall structural strength and stability of the connector.

[0020] Optionally, a threaded structure is provided on the wall of the second installation groove.

[0021] By adopting the above technical solution, the threaded structure increases the contact area and friction between the dispensing layer and the groove wall, enabling the dispensing layer to adhere more firmly to the groove wall, improving the structural stability and sealing performance. When subjected to vibration, the threads can effectively disperse and buffer the impact force, reducing the risk of the dispensing layer falling off or cracking, and enhancing the reliability of the connector in a vibrating environment. The presence of the threads helps to fill the tiny gaps between the dispensing layer and the groove wall, further improving the sealing performance and preventing the intrusion of dust, water vapor, etc. During the production process, the threaded structure facilitates controlling the distribution and thickness of the dispensing; during maintenance, it is also beneficial for the removal and reapplication of the dispensing layer.

[0022] In summary, the present application has at least the following beneficial effects:

[0023] 1. By adopting a specific structural design and combining the use of waterproof materials, the waterproof performance of the connector in water immersion, high-temperature, and high-humidity environments is ensured, thus maintaining the stable transmission of electricity.

[0024] 2. Preferably, multiple sealing and reinforcement measures are adopted, such as the dispensing layer, waterproof ring, and rib structure, etc. Due to the combined effect of these measures, the stability and durability of the connector in a high-frequency vibration environment are significantly enhanced.

[0032] The following further describes the present application in detail with reference to the accompanying drawings.

[0033] In this embodiment, referring to Figures 1-5 , a male-female pluggable industrial connector includes a male connector 1 and a female connector 2 adapted thereto. The main structure of the male connector 1 is a plastic shell 101 made of PA66+GF material with high temperature resistance, moisture resistance and high mechanical strength. A plurality of first installation channels 3 are provided inside the plastic shell 101, and these channels penetrate both sides of the plastic shell 101 for installing the female terminals 102. The female terminals 102 are made of phosphor bronze and plated with a layer of metal gold on the surface to improve the electrical conductivity and corrosion resistance. At one end of the plastic shell 101, an insertion slot 4 is provided, and the shape of the insertion slot 4 matches the docking part of the female connector 2. At the other end of the plastic shell 101, a first installation slot 5 is provided for accommodating the first glue application layer 103.

[0034] The female connector 2 is composed of an outer shell 201 and a glue core 202. The outer shell 201 is made of aluminum alloy and its surface is anodized to enhance corrosion resistance and wear resistance. The glue core 202 is also made of PA66+GF material, and a plurality of second installation channels 6 are provided inside it for installing the male terminals 203. The material and surface treatment of the male terminals 203 are the same as those of the female terminals 102. The outer shell 201 and the glue core 202 form a second installation slot 7 at the end far from the male connector 1, and the second installation slot 7 is used for accommodating the second glue application layer 204. The first glue application layer 103 and the second glue application layer 204 are made of epoxy resin material. By applying glue at the tail of the connector, the structural strength and sealing performance of the connector can be effectively enhanced.

[0035] The implementation principle of Embodiment 1 is as follows: During the assembly process, first, the female terminal 102 is inserted into the first installation channel 3 of the male connector 1 to ensure that the female terminal 102 is in close contact with the wall surface of the channel. Next, a waterproof ring 104 is installed in the insertion slot 4 of the plastic shell 101. The waterproof ring 104 is made of silicone material, has good elasticity and water resistance, and can provide an effective sealing effect when the male and female connectors 2 are inserted into each other. Then, glue-dropping treatment is carried out in the first installation groove 5, and epoxy resin glue drops are dropped into the groove. After the glue is cured, a first glue-dropping layer 103 is formed. The key to this step is to control the amount of glue dropped and the uniformity of the glue to ensure that the glue-dropping layer can evenly cover the entire bottom area of the groove, thereby enhancing the structural strength and sealing performance of the connector.

[0036] For the assembly of the female connector 2, first, the male terminal 203 is inserted into the second installation channel 6 of the glue core 202, and it is also necessary to ensure that the male terminal 203 is in close contact with the wall surface of the channel. Then, the glue core 202 is inserted into the outer shell 201 to ensure the fitting accuracy between the two. Next, glue-dropping treatment is carried out in the second installation groove 7 to form a second glue-dropping layer 204. Finally, the outer shell 201 and the glue core 202 are fixed through a fastening device (such as a screw) to complete the assembly of the female connector 2.

[0037] When the male connector 1 and the female connector 2 need to be inserted into each other, the insertion slot 4 of the male connector 1 is aligned with the docking part of the female connector 2 and inserted. During the insertion process, the waterproof ring 104 will be compressed and closely adhere to the contact surface between the two, thereby providing an effective waterproof and sealing effect. At the same time, the cooperation of the convex rib 8 and the groove 9 can also enhance the structural stability and shock absorption effect of the connector.

[0038] Embodiment 2

[0039] The difference between this embodiment and Embodiment 1 is that, referring to Figure 3 and Figure 4 , a further waterproof ring 104 is added in the insertion slot 4. This improvement enhances the waterproof performance of the connector during docking, ensuring that power transmission can be maintained stably even in a submerged environment. The waterproof ring 104 is made of silicone material, has good elasticity and water resistance, and can effectively fill the gap when the male and female connectors 2 are docked to prevent water from seeping in.

[0040] Embodiment 3

[0041] The difference between this embodiment and Embodiment 2 is that, referring to Figure 4 and Figure 5, a rib 8 structure is additionally provided in the insertion slot 4, and a groove 9 is correspondingly provided on the outer shell 201. When the male and female connectors 2 are inserted into each other, the rib 8 will tightly fit into the groove 9 to form a stable docking structure. This design not only improves the accuracy of the connector docking but also significantly enhances its seismic resistance, enabling it to maintain a reliable electrical connection even in a high-frequency vibration environment.

[0042] Embodiment 4

[0043] To further improve the seismic effect, on the basis of Embodiment 3, referring to Figure 4 , multiple ribs 8 are provided. The multiple ribs 8 can form multiple supports during the connector docking, thus more effectively resisting the interference of external vibrations on power transmission. At the same time, this design also increases the stability of the connector docking and extends its service life.

[0044] Embodiment 5

[0045] The difference in this embodiment is that, referring to Figure 4 and Figure 5 , mounting parts 10 are additionally provided on the plastic shell 101, and a mounting plate 11 with mounting holes 12 is correspondingly provided on the outer shell 201. Through these mounting parts 10 and mounting holes 12, the connector can be conveniently fixed and installed inside the device, improving its stability and reliability during use.

[0046] Embodiment 6

[0047] To ensure the assembly accuracy between the rubber core 202 and the outer shell 201, referring to Figure 2 and Figure 3 , a limiting groove 13 is recessed on the rubber core 202 in this embodiment, and a limiting part 14 is additionally provided on the outer shell 201 correspondingly. During the assembly process, the limiting part 14 will tightly fit into the limiting groove 13, thereby ensuring that the relative position between the rubber core 202 and the outer shell 201 remains fixed, improving the overall structural stability of the connector.

[0048] Embodiment 7

[0049] To simplify the alignment steps during installation, referring to Figure 2 and Figure 5 , a mounting calibration part 15 is additionally provided on the rubber core 202 in this embodiment, and a mounting calibration groove 16 is correspondingly provided inside the outer shell 201. During the installation process, just align the mounting calibration part 15 with the mounting calibration groove 16, and the accurate docking of the rubber core 202 can be quickly completed, greatly improving the installation efficiency of the rubber core 202 and the outer shell 201.

[0050] Embodiment 8

[0051] To further enhance the bonding force between the dispensing layer and the wall of the installation groove, referring toFigure 2 and Figure 3 to improve the structural strength of the connector. In this embodiment, a threaded structure 17 is added to the groove wall of the second installation groove 7. When filling the dispensing layer, the glue can adhere more tightly to the groove wall with the threaded structure 17, so as to form a more firm bond after curing.

[0052] The embodiments of this specific implementation manner are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
