Description

Technical Field

[0001] The invention relates to the technical field of electronic connectors, in particular to a PCB flange connector which can prevent tipping and is used for panel installation. Background Art

[0002] PCB flange connector is a connector for circuit boards (PCBs). It has many types and uses, such as right-angle PCB mounting socket flange plug, right-angle M5 waterproof 90-degree board-end PCB connector flange female socket, 2.4mm female 2-hole flange millimeter wave PCB vertical solderless connector and Phoenix Contact plug-in connectors. Among them, the M8 PCB flange connector used for panel installation has the advantages of anti-vibration and anti-interference. It is widely used in industrial automation, robots, medical equipment and other fields, which can effectively improve production efficiency and equipment stability. The M8 front-mounted socket PCB plug-in type is to directly insert the connector pins into the through holes on the PCB board and fix them by welding. Due to different use environments, the number of pins can be 3, 4, 5, 6, 8, etc. In some specific application environments, it is also necessary to have good anti-electromagnetic interference performance.

[0003] For example, an MCX RF coaxial connector with publication number CN212062911U includes a flange, an inner conductor pin and a support foot are arranged on one side of the flange, and an interface is arranged on the other side of the flange, the diameter of the end of the support foot is smaller than the diameter of the connecting section, and the edge of the interface is provided with a stepped groove. The small diameter of the end of the support foot is convenient for inserting into the reserved socket of the PCB board, and it saves time and effort when cutting off, greatly improving work efficiency. The edge of the outer conductor of the connector is provided with a stepped groove to prevent the 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 convenient for welding operation and solder immersion; the setting of the tin immersion hole makes the cable and the connector firmly connected.

[0004] In the prior art, the commonly used PCB plug-in connector requires that the conducting pins be first inserted into the corresponding sockets reserved on the PCB board, and then the solder is filled into the sockets by welding, so that the conducting pins inserted into the sockets of the PCB board are connected to the internal circuit of the PCB board. Since the size of the socket is usually slightly larger than the conducting pin, by filling solder between the conducting pin and the socket, poor contact can be avoided, and the PCB plug-in connector can be fixed on the PCB board at the same time.

[0005] With regard to 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, and although the metal pins are made of metal, they are still prone to deformation and skewness when squeezed, resulting in the inability to correctly align the PCB plug-in connector when inserted into the socket of the PCB board. The deformed and skewed metal pins need to be manually corrected before subsequent installation. On the other hand, the commonly used PCB plug-in connector is not effectively fixed to the PCB board before welding, which makes welding difficult when used on site, and is also troublesome to disassemble after welding.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original PCB flange connector. Summary of the invention

[0007] The technical solution of the present invention is aimed at the technical problem that the existing technical solutions are too simple, and provides a solution that is significantly different from the existing technologies.

[0015] Preferably, the guiding structure includes a second oil groove opened inside the needle seat connecting seat, and the second oil groove extends to the bottom of the needle seat connecting seat, and a connecting groove is opened inside the needle seat connecting seat to connect the first oil groove and the second oil groove, and a second insulating rod slidably matched with the second oil groove is arranged inside the second oil groove, and an insulating guiding disk slidably matched with the conductive column is fixed to the bottom of the second insulating rod.

[0016] Preferably, a second sealing ring that fits with the inner wall of the second oil groove is fixed to the top outer wall of the second insulating rod, and a through hole is opened at the center of the insulating guide disk, which is located on the outside of the first insulating rod.

During the sliding process, the deformed and skewed conductive column can be automatically corrected, so as to avoid the phenomenon of misalignment with the second plug hole of the PCB board during installation, thereby affecting the subsequent installation. The present invention is provided with a pin assembly. Since the elastic metal sheet is inclined outward at the bottom of the conductive column, when the insulating guide disk moves to the lower end of the elastic metal sheet, the elastic metal sheet that expands outward can be squeezed and contracted by the insulating guide disk. The connector is continuously pressed, and the first insulating rod and the insulating guide disk can be moved upward by using the correction assembly. When the insulating guide disk 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 plug hole, thereby connecting the elastic metal sheet with the circuit in the PCB board, so that welding is not required during the installation process of the connector, and the installation operation is simple, which is conducive to convenient disassembly during later maintenance.

At this time, the supporting foot just contacts the upper surface of the PCB board, and the metal grounding sheet and the supporting foot are used to support the PCB flange connector in four directions, so that the PCB flange connector can be prevented from tilting due to an external force collision during later use, and has a good anti-dumping effect, further improving the installation stability of the connector, and facilitating the alignment of the conductive column and the elastic metal sheet with the second plug hole during installation.

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.

[0031] As an optional embodiment, the anti-dumping assembly includes support feet 6 symmetrically installed on the outer wall of the needle hub connector 1, and the outer wall of the needle hub connector 1 is symmetrically installed with metal grounding plates 7, and the support feet 6 and the metal grounding plates 7 are vertically distributed.

[0032] The metal grounding plate 7 is configured as a harpoon structure, and the metal grounding plate 7 matches the first plug hole 22 .

[0033] 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 shrinks when squeezed, and resets and opens after passing through the first plug hole 22. The PCB board 21 is stuck in the depression on the outer side of the metal grounding plate 7. At this time, the supporting feet 6 just rest against the upper surface of the PCB board 21. The metal grounding plate 7 and the supporting feet 6 are used to support the PCB flange connector in four directions, which can prevent the PCB flange connector from tilting due to external force collision during later use, and has a good anti-dumping effect.

[0034] As an optional embodiment, the correction component includes a first oil groove 10 opened at the bottom center of the needle seat connecting seat 1, an annular plate 11 is fixed to the upper inner wall 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 from the first oil groove 10 is fixedly connected to the bottom of the first spring 12, a first sealing ring that fits the inner wall of the first oil groove 10 is fixed to the upper outer wall of the first insulating rod 13, a guide structure is provided on one side of the first oil groove 10 inside the needle seat connecting seat 1, and an oil balance structure is provided on the top of the first oil groove 10 inside the needle seat connecting seat 1.

[0035] The first oil groove 10 is filled with oil 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 top outer wall. When plugged in, the first insulating rod 13 slides in the first oil groove 10 against the top surface of the PCB board 21, and the first insulating rod 13 has the ability to move and reset by squeezing the first spring 12 between the annular plate 11. The squeezed filled oil is used as a driving force to enable the guide structure and the oil balance structure to operate.

[0036] As an optional embodiment, the guiding structure includes a second oil groove 14 opened inside the needle seat connecting seat 1, and the second oil groove 14 extends to the bottom of the needle seat connecting seat 1, and a connecting groove 15 is opened inside the needle seat connecting seat 1 to connect the first oil groove 10 and the second oil groove 14, and a second insulating rod 16 is provided inside the second oil groove 14 to slide with it, and an insulating guiding disk 17 is fixed to the bottom of the second insulating rod 16 to slide with the conductive column 4.

[0037] A second sealing ring that fits 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 , and a through hole is opened at the center of the insulating guide plate 17 located outside the first insulating rod 13 .

[0038] The first oil groove 10 is connected with the second oil groove 14 through the connecting groove 15, and the top of the second insulating rod 16 is also filled with oil. The second insulating rod 16 slides in a sealed manner through the second sealing ring on the top outer wall. When pushed by the oil, the second insulating rod 16 moves downward and drives the insulating guide plate 17 to slide downward on the outer wall of the evenly distributed conductive column 4. The insulating guide plate 17 and the conductive column 4 are fitted and slidable, and the deformed and skewed conductive column 4 can be automatically corrected. The through hole at the center of the insulating guide plate 17 can avoid contact with the first insulating rod 13 during movement, and they do not affect each other.

[0039] As an optional embodiment, the oil balance structure includes a third oil groove 18 opened inside the needle seat connecting seat 1 and connected to the first oil groove 10, the top of the third oil groove 18 is connected to a pressure relief groove opened inside the needle seat connecting seat 1, and the top inner wall of the third oil groove 18 is fixedly connected to a second spring 19, and the bottom of the second spring 19 is fixedly connected to a piston plate 20 that slides with the third oil groove 18.

[0040] In the final stage of pressing the PCB flange connector, that is, when the insulating guide disk 17 contacts the top of the PCB board 21 after correcting the conductive column 4 and the elastic metal sheet 9, as the PCB flange connector continues to be pressed toward the surface of the PCB board 21, the first insulating rod 13 and the insulating guide disk 17 will be resisted and pushed upward, and the oil in the first oil groove 10 and the second oil groove 14 will be squeezed. In order 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, wherein 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 exhaust is exhausted through the pressure relief groove inside the needle seat connecting seat 1 to balance the pressure.

[0041] Working principle: When the PCB flange connector is installed and used, the alignment standard is to insert the symmetrical metal grounding plate 7 into the corresponding first plug hole 22 on the PCB board 21. The metal grounding plate 7 is a harpoon-shaped structure. At the same time, the metal material has a certain elastic deformation ability, and the outer edge of the metal grounding plate 7 is arc-shaped. It shrinks when squeezed and resets and opens after passing through the first plug hole 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 foot 6 just rests on the upper surface of the PCB board 21. The metal grounding plate 7 and the support foot 6 are used to support the PCB flange connector in four directions, which can prevent the PCB flange connector from being tilted due to external force collision during later use, and has a good anti-dumping effect; When the bottom end of the metal grounding plate 7 is inserted into the first plug hole 22, the bottom of the first insulating rod 13 also contacts the upper surface of the PCB board 21. As the metal grounding plate 7 is completely inserted into the first plug hole 22, the first insulating rod 13 is squeezed and moves into the first oil groove 10. The first insulating rod 13 slides in the first oil groove 10 through the first sealing ring on the 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 connecting groove 15. The oil pushes the second insulating rod 16 to move downward. The second insulating rod 16 slides in the second oil groove 14 through the second sealing ring. The second insulating rod 16 pushes the insulating rod 16 to move downward. The guiding disk 17 slides downward on the outer wall of the conductive column 4, wherein the elastic force of the second spring 19 is greater than the corrective force required for the deformation of the conductive column 4 and the elastic force of the elastic metal sheet 9 when the elastic metal sheet 9 contracts and deforms. 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 can just enable the second insulating rod 16 to push the insulating guiding disk 17 to move to the bottom of the elastic metal sheet 9. During the sliding process of the insulating guiding disk 17, the outer wall of the conductive column 4 fits and slides with the insulating guiding disk 17, so that 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 plug hole 23.

[0042] When the insulating guide 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, and the connector is pressed continuously. The first insulating rod 13 and the insulating guide disk 17 are squeezed and move upward. At this time, the oil in the first oil groove 10 and the second oil groove 14 are squeezed. In order 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, the exhaust is exhausted through the pressure relief groove inside the needle seat connecting seat 1 to balance the pressure. Then, when the insulating guide disk 17 moves upward, the elastic metal sheet 9 will gradually expand, so that the outer wall of the elastic metal sheet 9 is against the inner wall of the second jack 23, thereby connecting the elastic metal sheet 9 with the circuit in the PCB board 21. Conversely, the bottom of the metal grounding sheet 7 is pressed to shrink it to complete the disassembly of the connector.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
