Description

Technical Field

[0001] The present invention relates to the technical field of electronic connectors, and in particular to a PCB flange connector for panel mounting that can prevent tipping over. Background Art

[0002] A PCB flange connector is a connector used for a printed circuit board (PCB). It has various types and uses, such as a right-angle PCB mounting socket flange plug, a right-angle M5 waterproof 90-degree board-end PCB connector flange female socket, a 2.4mm female head 2-hole flange millimeter-wave PCB vertical solderless connector, and a pluggable connector from Phoenix Contact, etc. Among them, the M8 type PCB flange connector applied to panel mounting has advantages such as anti-vibration and anti-interference. It is widely used in fields such as industrial automation, robotics, and medical equipment, and can effectively improve production efficiency and equipment stability. The M8 front-panel mounting socket PCB plug-in type inserts the pins of the connector directly into the through holes on the PCB board and fixes them by soldering. Due to different usage environments, the number of its pins can be 3, 4, 5, 6, 8, etc. In some specific application environments, it also needs to have good electromagnetic interference prevention performance.

[0003] For example, an MCX radio frequency coaxial connector with the publication number CN212062911U includes a flange. On one side of the flange, there are inner conductor pins and support feet. On the other side of the flange, there is an interface. The diameter of the end of the support foot is smaller than the diameter of the connecting section. A stepped groove is provided at the edge of the interface. The small diameter of the end of the support foot facilitates insertion into the reserved holes on the PCB board, and it is time-saving and labor-saving when cutting it off, greatly improving work efficiency. A stepped groove is provided at the edge of the outer conductor of this connector to prevent solder from flowing to the interface, and the opening of the stepped groove is larger than the opening of the outer conductor body, which is easy for welding operation and solder immersion; the setting of the tin dipping holes makes the connection between the cable and the connector firm.

[0004] In the prior art, for the commonly used PCB plug-in type connectors, the conduction pins need to be correspondingly inserted into the reserved holes on the PCB board first, and then solder is filled into the holes by welding to connect the conduction pins inserted into the holes on the PCB board with the internal circuit of the PCB board. Since the size of the holes is usually slightly larger than that of the conduction pins, filling solder between the conduction pins and the holes can avoid the phenomenon of poor contact, and at the same time fix the PCB plug-in type connector on the PCB board.

[0005] In view of the above-mentioned prior art, on the one hand, the metal pins of the PCB plug-in connector are in an exposed state during production and transportation. Although the metal pins are made of metal, they are still prone to deformation and skew when being squeezed, resulting in incorrect alignment when inserting the PCB plug-in connector into the jack of the PCB board. It is necessary to manually correct the deformed and skewed metal pins before subsequent installation. On the other hand, the commonly used PCB plug-in connectors are not effectively fixed to the PCB board before soldering, so it is difficult to solder on-site and it is also troublesome to disassemble after soldering.

[0006] In view of the above problems, there is an urgent need to innovate and design on the basis of the original PCB flange connector. Summary of the Invention

[0007] The technical solution of the present invention aims at the technical problem that the prior art solution is too single, and provides a solution significantly different from the prior art. Specifically, the purpose of the present invention is to provide a PCB flange connector for panel mounting that can prevent tipping, so as to solve the problem that after the metal pins of the PCB plug-in connector are deformed and skewed after being squeezed, it is necessary to manually correct the deformed and skewed metal pins before subsequent installation as mentioned in the above background technology.

[0008] To achieve the above object, the present invention provides the following technical solution: A PCB flange connector for panel mounting that can prevent tipping, including a pin seat connecting seat, and further including an installation component arranged outside the pin seat connecting seat for fixing after the connection end is inserted, a pin component uniformly arranged inside the pin seat connecting seat for mounting on the PCB board and fixing without soldering, an anti-tipping component arranged outside the pin seat connecting seat for improving the installation stability of the connector, and a correction component arranged inside the pin seat connecting seat for automatically correcting during the insertion with the PCB board;

[0009] The first jack and the second jack corresponding to the pin component and the anti-tipping component are arranged on the PCB board.

[0010] Preferably, the installation component includes a pin seat flange housing fixed on the outer wall of the upper end of the pin seat connecting seat, a locking nut threadedly engaged with the lower end of the pin seat flange housing, and an O-ring sleeved on the outer wall of the pin seat connecting seat below the locking nut.

[0011] Preferably, the pin component includes a conductive column arranged inside the pin seat connecting seat, and a pin head is fixedly arranged at the top end of the conductive column.

[0012] Preferably, elastic metal sheets are fixedly arranged at equal angles at the bottom end of the conductive column, and the elastic metal sheets are all inclined outwards.

[0013] Preferably, the anti-tipping assembly includes support feet symmetrically installed on the outer wall of the needle base connector, and metal grounding plates are symmetrically installed on the outer wall of the needle base connector. The support feet and the metal grounding plates are vertically distributed.

[0014] Preferably, the metal grounding plate is set in a harpoon structure and is matched with the first jack.

[0015] Preferably, the correction assembly includes a first oil groove opened at the center of the bottom of the needle base connector. An annular plate is fixed to the inner wall of the upper end of the first oil groove. A first spring is fixedly connected to the bottom of the annular plate. A first insulating rod extending out of the first oil groove is fixedly connected to the bottom of the first spring. A first sealing ring fitting with the inner wall of the first oil groove is fixedly installed on the outer wall of the upper end of the first insulating rod. A guiding structure is arranged on one side of the first oil groove inside the needle base connector, and an oil liquid balance structure is arranged on the top of the first oil groove inside the needle base connector.

[0016] Preferably, the guiding structure includes a second oil groove opened inside the needle base connector, and the second oil groove extends to the bottom of the needle base connector. A communication groove for communicating the first oil groove and the second oil groove is opened inside the needle base connector. A second insulating rod slidably matched with the second oil groove is arranged inside the second oil groove. An insulating guiding disk slidably matched with the conductive column is fixed to the bottom of the second insulating rod.

[0017] Preferably, a second sealing ring fitting with the inner wall of the second oil groove is fixedly installed on the outer wall of the top end of the second insulating rod. A through hole is opened at the center of the insulating guiding disk outside the first insulating rod.

[0018] Preferably, the oil liquid balance structure includes a third oil groove opened inside the needle base connector and communicating with the first oil groove. A pressure relief groove opened inside the needle base connector is communicated with the top of the third oil groove. A second spring is fixedly connected to the inner wall of the top end of the third oil groove. A piston plate slidably matched with the third oil groove is fixedly connected to the bottom of the second spring.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] In the present invention, a correction assembly is provided. During the process of the metal grounding plate being completely inserted into the first jack of the PCB board, the first insulating rod is extruded to squeeze the oil liquid into the second oil groove, so that the second insulating rod pushes the insulating guiding disk to slide downward on the outer wall of the conductive column and be flush with the bottom of the elastic metal sheet. During the sliding process, the deformed and skewed conductive column can be automatically corrected, avoiding the phenomenon of misalignment with the second jack of the PCB board during installation, thereby affecting the subsequent installation.

[0021] In the present invention, a pin component is provided. Since the elastic metal sheet inclines outward at the bottom of the conductive post, when the insulating alignment disc moves to the lower end of the elastic metal sheet, the outward-expanded elastic metal sheet can be squeezed by the insulating alignment disc and made to contract. By continuously pressing the connector, the first insulating rod and the insulating alignment disc can be moved upward by using the calibration component. When the insulating alignment disc moves upward, the elastic metal sheet will gradually expand, so that the outer wall of the elastic metal sheet abuts against and fits the inner wall of the second jack, thereby connecting the elastic metal sheet to the circuit in the PCB board. Thus, welding is not required during the installation of the connector, and the installation operation is simple, which is beneficial for convenient disassembly during later maintenance.

[0022] In the present invention, an anti-tipping component is provided. The symmetrical metal grounding sheets are correspondingly inserted into the corresponding first jacks on the PCB board. The metal grounding sheets are in a harpoon-shaped structure, and at the same time, the metal material has a certain elastic deformation ability, and the outer edge of the metal grounding sheet is arc-shaped. The PCB board is stuck in the recess on the outside of the metal grounding sheet. At this time, the support feet just abut against the upper surface of the PCB board. By using the metal grounding sheets and the support feet to support in four directions of the PCB flange connector, it can prevent the PCB flange connector from tilting due to external collision during later use, has a good anti-tipping effect, further improves the installation stability of the connector, and at the same time facilitates the alignment of the conductive post and the elastic metal sheet with the second jack during installation.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0034] Please refer to Figures 1 to 9 , the present invention provides a technical solution: a PCB flange connector for panel mounting that can prevent tipping, including a pin socket connection seat 1, and further including an installation component arranged outside the pin socket connection seat 1 for fixing after the connection end is inserted, a pin insertion component evenly arranged inside the pin socket connection seat 1 for being installed on the PCB board 21 and fixed without soldering, an anti-tipping component arranged outside the pin socket connection seat 1 for improving the installation stability of the connector, and a correction component arranged inside the pin socket connection seat 1 for automatically correcting during the insertion with the PCB board 21;

[0035] The PCB board 21 is provided with a first jack 22 and a second jack 23 corresponding to the pin insertion component and the anti-tipping component.

[0036] In the above embodiment, the operator can fix the PCB flange connector when plugging it with the connecting end through the installation component, and can plug it with the second socket 23 on the PCB board 21 through the pin component, so that the PCB flange connector does not need to be welded during the installation process, and the installation operation is simple, which is conducive to convenient disassembly during later maintenance. The anti-dumping component can be docked with the first socket 22 on the PCB board 21, which can prevent the PCB flange connector from tilting due to external force collision during later use, has a good anti-dumping effect, and further improves the installation stability of the PCB flange connector. The deformed and crooked pin component can be automatically corrected through the correction component to avoid misalignment with the second socket 23 on the PCB board 21 during installation, thereby affecting subsequent installation.

[0037] It should be noted that the PCB board 21 is a conventional existing structure, and the size settings of the first hole 22 and the second hole 23 are compatible with the model of the PCB flange connector used for installation, which will not be repeated here.

[0038] As an optional embodiment, the installation assembly includes a needle seat flange shell 2 fixed to the outer wall of the upper end of the needle seat connecting seat 1, and a locking nut 3 threadedly matched with the needle seat flange shell 2 is provided at the lower end of the needle seat connecting seat 1, and an O-ring 5 is provided on the outer wall of the needle seat connecting seat 1 below the locking nut 3.

[0039] After the connection end is docked with the PCB flange connector, the connection end can be fixed to the PCB flange connector by rotating the locking nut 3, wherein the O-ring 5 plays the role of waterproofing, dustproofing and sealing in the PCB flange connector. The above are all conventional existing technologies and will not be repeated here.

[0040] As an optional embodiment, the pin assembly includes a conductive column 4 arranged inside the needle seat connection seat 1, and a pin head 8 is fixedly arranged on the top of the conductive column 4.

[0041] The conductive pillar 4 and the pin head 8 can be made of conventional metal conductive materials, and the pin head 8 is used to connect the circuit with the docking end.

[0042] As an optional embodiment, elastic metal sheets 9 are fixed at equal angles to the bottom ends of the conductive pillars 4 , and the elastic metal sheets 9 are all arranged to tilt outwards.

[0043] The elastic metal sheet 9 can be made of copper alloy, which has good conductivity and elasticity. The outer wall of the elastic metal sheet 9 inclined outward can be contracted when squeezed. When inserted into the second socket 23, the expanded elastic metal sheet 9 can fit tightly against the inner wall of the second socket 23. According to the prior art, when in contact with the inner wall of the second socket 23, the elastic metal sheet 9 can be connected to the PCB board 21 for circuit connection.

[0044] As an alternative embodiment, the anti-tipping component includes support feet 6 symmetrically mounted on the outer wall of the needle seat connector 1, and metal grounding plates 7 are symmetrically mounted on the outer wall of the needle seat connector 1. The support feet 6 and the metal grounding plates 7 are vertically distributed.

[0045] The metal grounding plate 7 is arranged in a harpoon structure and is matched with the first jack 22.

[0046] The metal grounding plate 7 has a certain elastic deformation ability, and the outer edge of the metal grounding plate 7 is arc-shaped. It contracts when being squeezed and resets and expands after passing through the first jack 22. The PCB board 21 is stuck in the depression on the outer side of the metal grounding plate 7. At this time, the support feet 6 just abut against the upper surface of the PCB board 21. By using the metal grounding plate 7 and the support feet 6 to support in four directions of the PCB flange connector, it can prevent the PCB flange connector from tilting due to external force collision during later use, and has a good anti-tipping effect.

[0047] As an alternative embodiment, the calibration component includes a first oil groove 10 opened at the center of the bottom of the needle seat connector 1. An annular plate 11 is fixed to the inner wall of the upper end of the first oil groove 10. A first spring 12 is fixedly connected to the bottom of the annular plate 11. A first insulating rod 13 extending out of the first oil groove 10 is fixedly connected to the bottom of the first spring 12. A first sealing ring fitting the inner wall of the first oil groove 10 is fixed to the outer wall of the upper end of the first insulating rod 13. A guiding structure is arranged on one side of the first oil groove 10 inside the needle seat connector 1, and an oil liquid balance structure is arranged on the top of the first oil groove 10 inside the needle seat connector 1.

[0048] The first oil groove 10 is filled with oil liquid at the top of the first insulating rod 13. The first insulating rod 13 slides in a sealed manner through the first sealing ring on the outer wall of its top. During insertion, the first insulating rod 13 abuts against the top surface of the PCB board 21 and slides into the first oil groove 10, and the first insulating rod 13 has the ability to move and reset by squeezing the first spring 12 between it and the annular plate 11. The squeezed filled oil liquid can be used as a driving force to make the guiding structure and the oil liquid balance structure operate.

[0049] As an alternative embodiment, the guiding structure includes a second oil groove 14 opened inside the needle seat connector 1, and the second oil groove 14 extends to the bottom of the needle seat connector 1. A communication groove 15 for communicating the first oil groove 10 and the second oil groove 14 is opened inside the needle seat connector 1. A second insulating rod 16 slidably matched with the second oil groove 14 is arranged inside the second oil groove 14. An insulating guiding disk 17 slidably matched with the conductive column 4 is fixed to the bottom of the second insulating rod 16.

[0050] A second sealing ring fitting the inner wall of the second oil groove 14 is fixed to the outer wall of the top end of the second insulating rod 16. A through hole is opened at the center of the insulating guiding disk 17 on the outside of the first insulating rod 13.

[0051] Wherein, the first oil tank 10 and the second oil tank 14 are communicated through a communication tank 15. Similarly, the top of the second insulating rod 16 is also filled with oil. The second insulating rod 16 is sealed and slid through a second sealing ring on the outer wall of the top. When pushed by the oil, the second insulating rod 16 moves downward and drives the insulating alignment disc 17 to slide downward on the outer wall of the uniformly distributed conductive columns 4. The insulating alignment disc 17 and the conductive columns 4 are fitted and slidable, and the deformed and skewed conductive columns 4 can be automatically corrected. Moreover, the through hole at the center of the insulating alignment disc 17 can avoid contact with the first insulating rod 13 during movement, without affecting each other.

[0052] As an alternative embodiment, the oil balance structure includes a third oil tank 18 opened inside the pin socket connector 1 and communicated with the first oil tank 10. The top of the third oil tank 18 is communicated with a pressure relief tank opened inside the pin socket connector 1. And the inner wall of the top end of the third oil tank 18 is fixedly connected with a second spring 19. The bottom of the second spring 19 is fixedly connected with a piston plate 20 that is slidably matched with the third oil tank 18.

[0053] In the final stage of pressing the PCB flange connector, that is, when the insulating alignment disc 17 contacts the top of the PCB board 21 after correcting the conductive columns 4 and the elastic metal sheets 9, as the PCB flange connector continues to be pressed onto the surface of the PCB board 21, the first insulating rod 13 and the insulating alignment disc 17 will be resisted and pushed upward. The oil in the first oil tank 10 and the second oil tank 14 are both squeezed. To balance the oil in the first oil tank 10, the second oil tank 14 and the third oil tank 18, the oil will push the piston plate 20 to slide upward in the third oil tank 18 and squeeze the second spring 19. The elastic force of the second spring 19 is greater than the elastic force of the first spring 12. And when the piston plate 20 slides, the pressure is balanced by exhausting air through the pressure relief tank inside the pin socket connector 1.

[0054] Working principle: When the PCB flange connector is installed and used, the alignment standard is to insert the symmetrical metal grounding pieces 7 into the corresponding first jacks 22 on the PCB board 21. The metal grounding pieces 7 are in a harpoon shape, and the metal material has a certain elastic deformation ability. And the outer edge of the metal grounding piece 7 is arc-shaped, which shrinks when being squeezed and resets and expands after passing through the first jack 22. The PCB board 21 is stuck in the depression on the outer side of the metal grounding piece 7. At this time, the supporting feet 6 just abut against the upper surface of the PCB board 21. Using the metal grounding pieces 7 and the supporting feet 6 to support in four directions of the PCB flange connector can prevent the PCB flange connector from tilting due to external collision during later use, and has a good anti-tipping effect.

[0055] While the bottom end of the metal grounding piece 7 is inserted into the first jack 22, the bottom of the first insulating rod 13 also contacts the upper surface of the PCB board 21. As the metal grounding piece 7 is fully snapped into the first jack 22, the first insulating rod 13 is squeezed and moves into the first oil groove 10. The first insulating rod 13 seals and slides in the first oil groove 10 through the first sealing ring on its outer wall and squeezes the first spring 12. At the same time, the oil in the first oil groove 10 is squeezed into the second oil groove 14 through the communication groove 15, and the oil pushes the second insulating rod 16 to move downward. The second insulating rod 16 seals and slides in the second oil groove 14 through the second sealing ring, and the second insulating rod 16 pushes the insulating alignment disk 17 to slide downward on the outer wall of the conductive column 4. The elastic force of the second spring 19 is greater than the correction force required for the deformation of the conductive column 4 and the elastic force when the elastic metal sheet 9 undergoes shrinkage deformation. When the bottom of the first insulating rod 13 moves to be flush with the bottom of the elastic metal sheet 9, the amount of oil squeezed by the first insulating rod 13 is just enough to enable the second insulating rod 16 to push the insulating alignment disk 17 to move to the bottom of the elastic metal sheet 9. During the sliding process of the insulating alignment disk 17, since the outer wall of the conductive column 4 fits and slides with the insulating alignment disk 17, the deformed and skewed conductive column 4 can be automatically corrected, and the conductive column 4 and the elastic metal sheet 9 at its bottom can be correspondingly inserted into the second jack 23.

[0056] When the insulating alignment disk 17 moves to the lower end of the elastic metal sheet 9, the elastic metal sheet 9 at the bottom of each group of conductive columns 4 shrinks to the minimum. Continuing to press the connector, the first insulating rod 13 and the insulating alignment disk 17 will be squeezed and move upward. At this time, the oil in the first oil groove 10 and the second oil groove 14 are both squeezed. To balance the oil in the first oil groove 10, the second oil groove 14 and the third oil groove 18, the oil will push the piston plate 20 to slide upward in the third oil groove 18 and squeeze the second spring 19. And when the piston plate 20 slides, it exhausts air through the pressure discharge groove inside the needle seat connecting seat 1 to balance the pressure. Then when the insulating alignment disk 17 moves upward, the elastic metal sheet 9 will gradually expand, so that the outer wall of the elastic metal sheet 9 abuts against and fits the inner wall of the second jack 23, thereby connecting the elastic metal sheet 9 to the circuit in the PCB board 21. Conversely, pressing the bottom of the metal grounding piece 7 to make it shrink can complete the disassembly of the connector.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
