Description
Technical Field
[0001] This utility model relates to the field of power connection technology, and in particular to a multifunctional plug-in module for energy connection. Background Technology
[0002] A plug-in module, also known as a "dating connection module" or "pluggable connection module," is an electromechanical assembly used to achieve a fast, reliable, and reusable plug-and-play connection between two electrical / energy / signal systems. It consists of two parts: a male unit / plug end and a female unit / socket end. Through precise mechanical guidance and electrical contact engagement, it completes the transmission of power, signals, or data.
[0003] Traditional structures typically involve adding threaded holes to the surfaces of the guide seat and floating socket to facilitate screw insertion. However, this structure is only suitable for highly skilled operators. When different batches of operators perform the installation, the installation speed and efficiency vary due to differences in their skill levels. Furthermore, using ordinary non-magnetic threaded holes for screw fixing means that when working in confined spaces or blind spots, operators need to hold the screw upright with one hand and tighten it with the other, which can easily lead to problems such as screw slippage, misalignment, or falling off. This assembly process is cumbersome, has a low error tolerance, increases on-site maintenance time and labor costs, and is not conducive to standardized operations and rapid deployment. To address this, the inventors have proposed a multifunctional energy connection plug-in module that incorporates magnetic threaded holes to solve the aforementioned technical problems of needing to hold the screw upright with one hand and tighten it with the other, which can easily lead to screw slippage. Utility Model Content
[0004] In order to overcome the shortcomings mentioned above, the utility model aims to provide a technical solution that can solve the above problems.
[0005] A multifunctional energy connection plug-in module includes a male unit component and a female unit component. The male unit component includes a guide seat, a male interface module, a male grounding plug, and a plug module. The female unit component includes a floating socket, a female interface module, a female grounding socket, and a female grounding interface. The surfaces of the guide seat and the floating socket are provided with magnetic nails for auxiliary positioning and connection. The magnetic nails are in the shape of a nail, and one end of the magnetic nail is connected to a fixing washer for auxiliary fixing of the magnetic nail. The magnetic nail is used to assist screw alignment. The surface of the guide seat is provided with a guide pin, and the surface of the guide pin is connected with an iron card plate. The middle of the floating socket is provided with a connecting groove that matches the guide pin. The inner surface of the connecting groove is provided with a magnetic block that matches the card plate. The magnetic block has a raised structure. The card plate is located at both ends of the surface of the guide pin and has an open structure in the middle. This structure uses a card plate made of iron, which can be attracted by a magnetic block. The central opening structure allows the magnetic block to be directly aligned with and attracted to both ends of the card plate when inserted into the connecting slot, achieving automatic centering and improving insertion accuracy. The opening also avoids the obstruction of the middle solid, making the magnetic lines of force more concentrated at both ends, enhancing the adsorption stability. If there is a slight deviation during the insertion of the guide pin into the connecting slot, the magnetic attraction between the magnetic block and the card plate can be guided by the magnetic force generated by the opening area, which can automatically correct the position and improve the fault tolerance rate. Meanwhile, by adding magnetic nails to the surfaces of the guide seat and floating socket, when the male and female unit assemblies are connected, screws are needed to pass through the guide seat and floating socket for locking. This structure improves upon the traditional threaded hole by using a magnetic nail with a threaded hole in the middle to work with an external screw for assembly. When the external screw approaches the threaded hole of the magnetic nail, the magnetic force generated by the magnetic nail attracts the screw, thus allowing the screw to fit into the threaded hole in the middle of the magnetic nail. The operator only needs to straighten the screw and tighten it, which improves work efficiency and makes it easier for operators of different skill levels to use.
[0006] Furthermore, the male unit component includes a first pin header module and a second pin header module. Both the first pin header module and the second pin header module are equipped with pins. The first pin header module has more pins than the second pin header module. The first pin header module and the second pin header module are located between the male terminal interface module and the male terminal grounding plug. The first pin row module is used to transmit high-density signals, data, or auxiliary power, such as communication signals, control commands, and sensor feedback. It requires a large number of pins. The second pin row module has fewer pins and is used for high-current main power transmission or critical safety signals. It allows each pin to carry a higher current, reducing heat generation and voltage drop. The combination of more pins and fewer pins achieves functional separation of signal and power, improving the system's electromagnetic compatibility (EMC) and reliability.
[0007] Furthermore, the female unit assembly includes a first row of female sockets and a second row of female sockets. The surfaces of the first row of female sockets and the second row of female sockets are provided with connection holes for mutual connection with PIN pins. The connection holes and PIN pins are paired with each other. The two rows of female sockets correspond to the first row of pin modules and the second row of pin modules of the male end, respectively, forming corresponding channel pairings to avoid misconnection or short circuit. The inner wall of the connection hole is provided with an elastic contact piece to provide constant positive pressure after the PIN pin is inserted. The positions of the female socket and the male pin header correspond to each other. Combined with the magnetic positioning effect generated during the insertion of the guide pin into the connecting slot, it ensures that the grounding terminal of the plug module is connected first, followed by the signal / power terminal; and the signal / power terminal is disconnected first, followed by the grounding terminal. This timing sequence prevents arcing during live plugging and unplugging, thus improving operational safety.
[0008] Furthermore, the surfaces of the plug module and the female grounding interface are respectively provided with baffles and partitions. The highest point of the baffles and partitions is higher than the surfaces of the plug module and the female grounding interface. Both the baffles and partitions are in the form of sheet trapezoidal structures. As raised physical barriers, the baffles and partitions can effectively prevent foreign objects such as fingers from accidentally contacting the live plug module or the female grounding interface during installation, thereby improving operational safety. Moreover, the sheet trapezoidal structure provides high bending stiffness with limited material, and can withstand lateral forces or external impacts during insertion and removal. The improved shape extends the service life of the baffles and partitions themselves.
[0009] Furthermore, both the male and female unit components are provided with aluminum support rails on their surfaces. The support rails are respectively installed on the surfaces at both ends of the male and female unit components. The aluminum support rails installed at both ends of the components can form a frame structure. This structure can effectively resist the deformation caused by bending, twisting and vibration of the male and female unit components during installation or use. The surface of the support rails is provided with T-slots. The surfaces of the male end interface module, male end grounding plug, plug module, female end interface module, female end grounding socket and female end grounding interface are provided with protruding structures. The protruding structures are installed with the T-slots to play the role of fixing the support rails.
[0010] Furthermore, the surface of the guide seat is provided with anti-slip grooves to increase friction and shock-absorbing grooves to reduce force dispersion. The anti-slip grooves are transverse groove structures, which increase the contact friction coefficient between fingers or tools and the surface of the guide seat, preventing slippage during insertion, removal, handling, or fastening. By adding shock-absorbing grooves, the guide seat has a certain elastic deformation space. When the male and female units are quickly connected or the equipment is vibrating during operation, the material micro-deformation absorbs kinetic energy, reducing the impact force transmitted to the PIN pin, grounding terminal, or internal solder joint. When insertion or removal force or external load is applied to the guide seat, the shock-absorbing grooves can act as stress release areas, preventing stress concentration from being transmitted to the guide pin, magnetic nail, or interface module.
[0011] Furthermore, the guide pin has a raised structure, and its surface is provided with several anti-slip blocks to increase contact points. The anti-slip blocks are linearly arranged on the surface of the guide pin, and the distance between two adjacent anti-slip blocks is equidistant. This equidistant linear arrangement ensures that the load distribution of the anti-slip blocks is uniform along the length of the guide pin, avoiding material wear, deformation, or jamming caused by local stress concentration. The anti-slip blocks are in the shape of right-angled triangles, playing a partial guiding role. Through multiple anti-slip blocks forming a distributed guiding contact surface with the inner wall of the connecting groove, compared with single-point or asymmetrical structures, it can more effectively correct small angular deviations and guide the male and female units to accurately coaxially insert.
[0012] Compared with the prior art, the beneficial effects of this utility model are: by improving the traditional threaded hole, the assembly is carried out by a magnetic nail with a threaded hole in the middle and an external screw. When the external screw approaches the threaded hole of the magnetic nail, the magnetic force generated by the magnetic nail attracts the screw, so that the screw is put into the threaded hole in the middle of the magnetic nail. The operator only needs to straighten the screw and tighten it, which improves work efficiency and makes it easy for operators with different skill levels to use. In addition, by adding a card plate and a magnetic block, the magnetic block can be directly aligned with and attracted to both ends of the card plate when inserted into the connecting slot, achieving automatic centering and improving insertion accuracy. The opening avoids the obstruction of the middle solid, making the magnetic lines of force more concentrated at both ends, enhancing the attraction stability. If there is a slight deviation during the insertion of the guide pin into the connecting slot, the magnetic attraction between the magnetic block and the card plate can be guided by the magnetic force generated by the opening area, which can automatically correct the position and improve the fault tolerance rate. It is equipped with floating mating mounts on both sides, which can achieve precise mating and avoid pin position deviation. It can also be configured with modules as needed to provide multiple uses, with a high degree of operational flexibility to meet various needs. Attached Figure Description

Detailed Implementation
[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0015] For this embodiment, please refer to Figures 1-10 The specific implementation of this multifunctional energy connection plug-in module includes a male unit component and a female unit component. The male unit component includes a guide seat 1, a male terminal interface module 2, a male terminal grounding plug 3, and a plug module 4. The female unit component includes a floating socket 5, a female terminal interface module 6, a female terminal grounding socket 7, and a female terminal grounding interface 8. The surfaces of the guide seat 1 and the floating socket 5 are provided with magnetic nails 9 for auxiliary positioning and connection. The magnetic nails 9 are in the shape of a nail, and one end of the magnetic nail 9 is connected to a fixing washer 10 for auxiliary fixing of the magnetic nail 9. The magnetic nail 9 is used to assist screw alignment. The surface of the guide seat 1 is provided with a guide pin 11, and the surface of the guide pin 11 is connected with an iron card plate 12. The middle of the floating socket 5 is provided with a connecting groove 13 that is matched and installed with the guide pin 11. The inner surface of the connecting groove 13 is provided with a magnetic block 14 that is matched with the card plate 12. The magnetic block 14 has a raised structure. The card plate 12 is located at both ends of the surface of the guide pin 11 and has an open structure in the middle. This structure uses a card plate 12 made of iron, which can be attracted by a magnetic block 14. The central opening structure allows the magnetic block 14 to be directly aligned with and attracted to both ends of the card plate 12 when inserted into the connecting slot 13, achieving automatic centering and improving insertion accuracy. The opening also avoids the obstruction of the middle solid, making the magnetic lines of force more concentrated at both ends, enhancing the adsorption stability. If there is a slight offset during the insertion of the guide pin 11 into the connecting slot 13, the magnetic attraction between the magnetic block 14 and the card plate 12 can be guided by the magnetic force generated by the opening area, which can automatically correct the position and improve the fault tolerance rate. Meanwhile, by adding magnetic nails 9 to the surfaces of the guide seat 1 and the floating socket 5, when the male unit assembly and the female unit assembly are connected, screws need to be passed through the guide seat 1 and the floating socket 5 for locking. The traditional structure usually only adds threaded holes to the surfaces of the guide seat 1 and the floating socket 5 to facilitate the screw's entry. However, this structure is suitable for operators with high skill levels. When different batches of operators perform the installation, the installation speed and efficiency will vary due to differences in their skill levels. This structure improves upon the traditional threaded hole by using a magnetic nail 9 with a threaded hole in the middle to assemble with an external screw. When the external screw approaches the threaded hole of the magnetic nail 9, the magnetic force generated by the magnetic nail 9 attracts the screw, allowing the screw to fit into the threaded hole in the middle of the magnetic nail 9. The operator only needs to straighten the screw and tighten it, which improves work efficiency and makes it easier for operators with different skill levels to use.
[0016] The male unit component includes a first pin header module 15 and a second pin header module 16. Both the first pin header module 15 and the second pin header module 16 are equipped with pins 17. The number of pins 17 on the surface of the first pin header module 15 is greater than that on the second pin header module 16. The first pin header module 15 and the second pin header module 16 are located between the male terminal interface module 2 and the male terminal grounding plug 3. The first pin header module 15 is used to transmit high-density signals, data, or auxiliary power, such as communication signals, control commands, and sensor feedback. It requires a large number of pins 17. The second pin header module 16 has fewer pins 11 and is used for high-current main power transmission or critical safety signals. This allows each pin 17 to carry a higher current, reducing heat generation and voltage drop. The combination of more pins and fewer pins achieves functional separation of signal and power, improving the system's electromagnetic compatibility (EMC) and reliability.
[0017] The female unit assembly includes a first row of female sockets 18 and a second row of female sockets 19. The surfaces of the first row of female sockets 18 and the second row of female sockets 19 are provided with connection holes 20 for connecting with PIN pins 17. The connection holes 20 are paired with the PIN pins 17. The two rows of female sockets correspond to the first row of pin modules 15 and the second row of pin modules 16 of the male terminals, respectively, forming corresponding channel pairings to avoid misconnection or short circuit. The inner wall of the connection hole 20 is provided with an elastic contact piece (not shown) to provide constant positive pressure after the PIN pin 17 is inserted. The positions of the female socket and the male pin header correspond to each other. Combined with the magnetic positioning effect generated when the guide pin 11 is inserted into the connecting slot 13, it ensures that the grounding terminal of the plug module is connected first, followed by the signal / power terminal; and the signal / power terminal is disconnected first, followed by the grounding terminal. This timing sequence prevents arcing during plugging and unplugging and improves operational safety.
[0018] The surfaces of the plug module 4 and the female grounding interface 8 are respectively provided with a baffle 21 and a partition 22. The highest point of the baffle 21 and the partition 22 is higher than the surface of the plug module 4 and the female grounding interface 8. Both the baffle 21 and the partition 22 are in the form of a sheet trapezoidal structure. As a raised physical barrier, the baffle 21 and the partition 22 can effectively prevent foreign objects such as fingers from accidentally contacting the live plug module 4 or the female grounding interface 8 during installation, thereby improving operational safety. Moreover, the sheet trapezoidal structure provides high bending stiffness with limited material, and can withstand lateral forces or external impacts during the insertion and removal process. The improved shape extends the service life of the baffle 21 and the partition 22 themselves.
[0019] Both the male and female unit components are provided with aluminum support rails 23. The support rails 23 are respectively installed on the surfaces of the male and female unit components at both ends. The aluminum support rails 23 installed at both ends of the components can form a frame structure. This structure can effectively resist the deformation caused by bending, twisting and vibration of the male and female unit components during installation or use. The surface of the support rails 23 is provided with T-slots. The surfaces of the male end interface module 2, male end grounding plug 3, plug module 4, female end interface module 6, female end grounding socket 7 and female end grounding interface 8 are provided with protruding structures. The protruding structures are installed with the T-slots to fix the support rails 23.
[0020] The surface of the guide seat 1 is provided with anti-slip grooves 24 for increasing friction and shock-absorbing grooves 25 for reducing force dispersion. The anti-slip grooves 24 are transverse groove structures, which increase the contact friction coefficient between fingers or tools and the surface of the guide seat 1, preventing slippage during insertion, removal, handling or fastening. By adding shock-absorbing grooves 25, the guide seat 1 has a certain elastic deformation space. When the male and female units are quickly connected or the equipment is vibrating, the material micro-deformation absorbs kinetic energy, reducing the impact force transmitted to the PIN pin 17, grounding terminal or internal solder joint. When the insertion or removal force or external load is applied to the guide seat 1, the shock-absorbing grooves 25 can serve as stress release areas to prevent stress concentration from being transmitted to the guide pin 11, magnetic nail 9 or interface module.
[0021] The guide pin 11 has a raised structure, and its surface is provided with several anti-slip blocks 26 to increase contact points. The anti-slip blocks 26 are linearly arranged on the surface of the guide pin 11, and the distance between two adjacent anti-slip blocks 26 is equidistant. This equidistant linear arrangement ensures that the load distribution of the anti-slip blocks 26 is uniform along the length of the guide pin, avoiding material wear, deformation or jamming caused by local stress concentration. The anti-slip blocks 26 are right-angled triangular in shape and play a partial guiding role. The multiple anti-slip blocks 26 form a distributed guiding contact surface with the inner wall of the connecting groove 13. Compared with single-point or asymmetrical structures, this can more effectively correct small angular deviations and guide the male and female units to accurately coaxially insert.
[0022] The key design features of this invention are as follows: This structure improves upon the traditional threaded hole by using a magnetic nail 9 with a threaded hole in the middle to assemble with an external screw. When the external screw approaches the threaded hole of the magnetic nail 9, the magnetic force generated by the magnetic nail 9 attracts the screw, thereby allowing the screw to fit into the threaded hole in the middle of the magnetic nail 9. The operator only needs to straighten the screw and tighten it, which improves work efficiency and makes it easier for operators of different skill levels to use. Furthermore, by adding the card plate 12 and the magnetic block 14, the magnetic block 14 can be directly aligned with and attracted to both ends of the card plate 12 when inserted into the connecting slot 13, achieving automatic centering and improving insertion accuracy. The opening avoids the obstruction of the middle solid, making the magnetic lines of force more concentrated at both ends, enhancing the attraction stability. If there is a slight offset during the insertion of the guide pin 11 into the connecting slot 13, the magnetic attraction between the magnetic block 14 and the card plate 12 can be guided by the magnetic force generated by the opening area, which can automatically correct the position and improve the fault tolerance rate.
