Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a VGA male connector. Background Technology

[0002] A VGA male connector is a physical interface device used to transmit video signals, primarily for transferring video signals from one device to another. It is an analog display standard widely used for connections between computer monitors, projectors, and other display devices.

[0003] In existing technology, most connectors use washers to increase the distance between the control panel and the connector. Most do not have a similar protrusion design to precisely measure the distance between the control panel and the connector. Since the washers may loosen or deform during use, this may result in the distance between the panel and the connector being too tight or too loose during installation, affecting the contact quality and signal transmission stability. This can lead to significant errors during assembly, resulting in inconsistent connection quality between different devices.

[0004] Furthermore, the manufacturing cost of existing gaskets is higher than that of the punching process. At the same time, the gaskets require complex alignment and adjustment steps to ensure the correct installation position, which increases the assembly difficulty and time cost, adds processes and reduces work efficiency. To address this, the inventors have proposed a VGA male connector that solves the aforementioned technical problem of the distance between the control panel and the connector through a simplified structure. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] A VGA male connector includes a metal shell, a plastic body, and metal terminals. The metal shell, plastic body, and metal terminals are detachable. The surface of the plastic body is fitted with metal parts. The metal terminals are L-shaped. One horizontal end of the metal terminal is connected to a cylindrical conductor. The vertical end of the metal terminal is flat. A groove is provided at the flat end of the metal terminal to reduce the surface volume of the metal terminal. The surface of the metal shell is provided with a limiting structure for limiting the distance between the outer panel and the connector. The limiting structure is a protrusion that rises to one end.

[0007] This structure uses two protrusions stamped on each side of the connector's metal housing. When the connector is assembled with an external mechanism, the distance between the control panel and the connector can be adjusted by the height of the protrusions. That is, when the mechanism panel is locked with the connector, the panel is pressed against the protrusions after contacting them, so that the panel can no longer move forward, thus accurately ensuring the distance between the panel and the connector.

[0008] The height of the added protrusions can control the distance between the control panel and the connector, preventing it from being too tight or too loose. This avoids connector damage caused by excessive tightness or poor contact caused by excessive looseness. As long as the panel contacts the protrusions, a consistent installation distance can be guaranteed, improving assembly consistency and reliability. In addition, the protrusions provide extra support points, making the connector more stable after installation and reducing the risk of loosening or displacement caused by vibration or other external forces. By limiting further movement of the panel, the potential shaking of the connector during use is effectively reduced, improving overall stability.

[0009] On the other hand, the bumps can absorb external impact to a certain extent, reduce the stress directly transmitted to the internal hardware terminals and conductors, extend the service life of the connector, and ensure that the panel and connector maintain the optimal distance, avoiding poor contact problems caused by improper installation, ensuring the stability of signal transmission, helping to shield external electromagnetic interference, and improving the reliability of electrical performance.

[0010] Furthermore, the hardware is in the form of a harpoon structure, and the hardware is respectively installed on the left and right ends of the plastic body and extends beyond the surface of the plastic body. The protrusions are located on the left and right ends of the hardware shell and are symmetrical to each other.

[0011] The harpoon structure of the hardware increases the gripping force between the connector and the panel or housing of the external mechanism, thereby providing additional mechanical gripping force to prevent the connector from loosening or falling off during use. The symmetrical arrangement of the protrusions on the left and right ends of the hardware housing provides balanced support, making the force distribution between the connector and the external panel more uniform and enhancing the overall stability.

[0012] Furthermore, the hardware is connected to the plastic body by hardware rivets. One end of the hardware rivet penetrates the surface of both the hardware shell and the plastic body. The surfaces of the hardware rivet and the plastic body are provided with through holes for mating and installation with the hardware rivet. One end of the hardware rivet is provided with a limiting plate to increase the connection stability. The diameter of the front end of the hardware rivet away from the limiting plate is larger than the diameter of the middle part of the hardware rivet.

[0013] The front diameter of the hardware rivet is larger than the middle diameter, forming a structure similar to a "rivet head". This effectively prevents the hardware rivet from coming loose from the through hole, ensuring a tight connection between the connector components and the hardware. The limiting plate further enhances the fixing effect of the hardware rivet, avoiding loosening or displacement caused by external forces, thereby improving the stability of the overall structure. This design significantly improves the durability of the connector and extends the service life of the product.

[0014] Furthermore, the surface of the hardware housing is provided with a raised boss, the boss has an open structure, and the inner wall of the boss is provided with a number of raised structures to increase connection stability. The end of the hardware terminal connected to the conductor is installed inside the boss.

[0015] The raised structure on the inner wall of the boss can fit tightly with the hardware terminal, providing additional mechanical gripping force to prevent the hardware terminal from loosening or shifting during use. In addition, the open structure of the boss provides a clear installation position, allowing the corresponding connector to be quickly and accurately inserted into the designated position, reducing alignment and adjustment time. The raised structure on the inner wall can apply a certain clamping force to the hardware terminal after installation, ensuring that it always stays in the correct position and avoiding displacement caused by vibration or other external forces.

[0016] Furthermore, the surface of the plastic body is provided with a plurality of through holes for defining the positions of the hardware terminals, and the through holes penetrate the surfaces of both ends of the plastic body;

[0017] The use of through holes provides corresponding mounting positions for the hardware terminals, allowing one end of the hardware terminal to be accurately inserted into the designated position. This avoids poor contact or assembly errors caused by positional misalignment. Furthermore, the through holes penetrate the surface of both ends of the plastic body, enabling the hardware terminals to be fully limited throughout their movement, reducing the possibility of displacement during use, improving the overall structural stability, reducing the contact resistance between the terminals and conductors, thereby improving the stability and reliability of signal transmission, helping to maintain consistent spacing between hardware terminals, avoiding signal crosstalk or electromagnetic interference, and improving electrical performance.

[0018] Furthermore, one end of the plastic body is connected to a plastic back cover, and the plastic body and the plastic back cover are detachable. The surface of the plastic back cover is provided with several limiting grooves for limiting the position of the hardware terminals.

[0019] The limiting groove can apply a certain clamping force to the hardware terminal, reducing the possibility of loosening or displacement during use and improving the stability of the overall structure. Users can easily remove the plastic back cover as needed to replace or repair the hardware terminal. During installation, simply match the hardware terminal with the corresponding limiting groove to complete the fixation, reducing alignment and adjustment time and improving assembly efficiency.

[0020] Furthermore, the junction between the flat end of the hardware terminal and the conductor is arranged in an unfolded shape. The unfolded shape provides a structure with varying widths, which helps to reduce the inductance of the circuit, thereby improving the signal transmission quality. The narrower arrangement can shorten the length of the current loop, reduce electromagnetic interference (EMI) and radio frequency interference (RFI), reduce impedance, improve grounding stability, and help ensure signal integrity and reliable operation of the equipment.

[0021] Compared with the prior art, the beneficial effects of this utility model are: by stamping two protrusions on each side of the connector's metal housing, when the connector is assembled with an external mechanism, the distance between the control panel and the connector can be adjusted by the height of the protrusions. That is, when the mechanism panel is locked with the connector, after the panel contacts the protrusions, it is pressed down by the protrusions, so that the panel can no longer move forward, thereby accurately ensuring the distance between the panel and the connector.

[0022] In addition, by providing a groove at one end of the flat metal terminal to reduce the surface volume of the metal terminal, the stability of the overall structure is improved, the contact resistance between the terminal and the conductor is reduced, thereby improving the stability and reliability of signal transmission, helping to maintain consistent spacing between metal terminals, avoiding signal crosstalk or electromagnetic interference, and improving electrical performance.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0039] For this embodiment, please refer to Figures 1-14 A VGA male connector specifically implemented therein includes a metal housing 1, a plastic body 2, and metal terminals 3. The metal housing 1, plastic body 2, and metal terminals 3 are detachable. A metal part 4 is mounted on the surface of the plastic body 2. The metal terminals 3 have an L-shaped structure. One horizontal end of the metal terminals 3 is connected to a cylindrical conductor 7. The vertical end of the metal terminals 3 has a flat structure. A groove 5 is provided at the flat end of the metal terminals 3 to reduce the surface volume of the metal terminals 3. The surface of the metal housing 1 is provided with a limiting structure for limiting the distance between the outer panel and the connector. The limiting structure is a protrusion 8 that rises to one end.

[0040] This structure uses two protrusions 8 stamped on each side of the connector's metal housing 1. When the connector is assembled with an external mechanism, the distance between the control panel and the connector can be adjusted by the height of the protrusions 8. That is, when the mechanism panel is locked with the connector, the panel is pressed against the protrusions 8 after contacting them, so that the panel can no longer move forward, thus accurately ensuring the distance between the panel and the connector.

[0041] The height of the added protrusion 8 can control the distance between the control panel and the connector, preventing it from being too tight or too loose. This avoids connector damage caused by excessive tightness or poor contact caused by excessive looseness. As long as the panel contacts the protrusion 8, a consistent installation distance can be guaranteed, improving assembly consistency and reliability. In addition, the protrusion 8 provides an extra support point, making the connector more stable after installation and reducing the risk of loosening or displacement caused by vibration or other external forces. By limiting further movement of the panel, it effectively reduces the possible shaking of the connector during use and improves overall stability.

[0042] On the other hand, the bump 8 can absorb external impact to a certain extent, reduce the stress directly transmitted to the internal hardware terminals 3 and conductors 7, extend the service life of the connector, and ensure that the optimal distance is maintained between the panel and the connector, avoiding poor contact problems caused by improper installation, ensuring the stability of signal transmission, helping to shield external electromagnetic interference, and improving the reliability of electrical performance.

[0043] The hardware component 4 has a harpoon structure. The hardware component 4 is installed on the left and right ends of the plastic body 2 and extends beyond the surface of the plastic body 2. The protrusions 8 are located on the left and right ends of the hardware shell 1 and are symmetrical to each other.

[0044] The harpoon structure of the hardware component 4 increases the gripping force between the connector and the panel or housing of the external mechanism, thereby providing additional mechanical gripping force to prevent the connector from loosening or falling off during use. The symmetrical arrangement of the protrusions 8 at the left and right ends of the hardware housing 1 provides balanced support force, making the force distribution between the connector and the external panel more uniform and enhancing the overall stability.

[0045] The hardware component 4 is connected to the plastic body 2 by hardware rivets 6. One end of the hardware rivet 6 penetrates the surface of the hardware shell 1 and the plastic body 2 respectively. The surfaces of the hardware rivet 6 and the plastic body 2 are provided with through holes for matching and installing the hardware rivet 6. One end of the hardware rivet 6 is provided with a limiting plate 10 for increasing connection stability. The diameter of the front end of the hardware rivet 6 away from the limiting plate 10 is larger than the diameter of the middle part of the hardware rivet 6.

[0046] The front diameter of the hardware rivet 6 is larger than the middle diameter, forming a structure similar to a "rivet head". This effectively prevents the hardware rivet 6 from coming loose from the through hole, ensuring a tight connection between the connector components and the hardware 4. The limiting plate 10 further enhances the fixing effect of the hardware rivet 6, avoiding loosening or displacement caused by external forces, thereby improving the stability of the overall structure. This design significantly improves the durability of the connector and extends the service life of the product.

[0047] The surface of the hardware housing 1 is provided with a raised boss 9, which has an open structure. The inner wall of the boss 9 is provided with several raised structures to increase connection stability. The end of the hardware terminal 3 connected to the conductor 7 is installed inside the boss 9.

[0048] The raised structure on the inner wall of the boss 9 can fit tightly with the hardware terminal 3, providing additional mechanical gripping force to prevent the hardware terminal 3 from loosening or shifting during use. In addition, the open structure of the boss 9 provides a clear installation position, allowing the corresponding connector to be quickly and accurately inserted into the designated position, reducing alignment and adjustment time. The raised structure on the inner wall can apply a certain clamping force to the hardware terminal 3 after installation, ensuring that it always stays in the correct position and avoiding displacement caused by vibration or other external forces.

[0049] The surface of the plastic body 2 is provided with a plurality of through holes for defining the position of the hardware terminals 3, and the through holes penetrate the surfaces of both ends of the plastic body 2;

[0050] The use of through holes provides corresponding mounting positions for the hardware terminals 3, allowing one end of the hardware terminal 3 to be accurately inserted into the designated position. This avoids poor contact or assembly errors caused by positional misalignment. Furthermore, the through holes penetrate the surface of both ends of the plastic body 2, enabling the hardware terminals 3 to be fully limited throughout their movement. This reduces the possibility of displacement during use, improves the overall structural stability, and reduces the contact resistance between the hardware terminals 3 and the conductor 7. Consequently, it enhances the stability and reliability of signal transmission, helps maintain consistent spacing between the hardware terminals 3, avoids signal crosstalk or electromagnetic interference, and improves electrical performance.

[0051] One end of the plastic body 2 is connected to a plastic back cover 11. The plastic body 2 and the plastic back cover 11 are detachable. The surface of the plastic back cover 11 is provided with several limiting grooves 12 for limiting the position of the hardware terminals 3.

[0052] The limiting groove 12 can apply a certain clamping force to the hardware terminal 3, reducing the possibility of loosening or displacement during use and improving the stability of the overall structure. Users can easily remove the plastic back cover 11 as needed to replace or repair the hardware terminal 3. During installation, simply pair the hardware terminal 3 with the corresponding limiting groove 12 to complete the fixation, reducing the alignment and adjustment time and improving the assembly efficiency.

[0053] The junction between the flat end of the hardware terminal 3 and the conductor 7 is arranged in an unfolded shape. The unfolded shape provides a structure with varying widths, which helps to reduce the inductance of the circuit, thereby improving the signal transmission quality. The narrower setting can shorten the length of the current loop, reduce electromagnetic interference (EMI) and radio frequency interference (RFI), reduce impedance, improve grounding stability, and help ensure signal integrity and reliable operation of the equipment.

[0054] The key design feature of this utility model is that two protrusions 8 are stamped on each side of the connector hardware shell 1. When the connector is assembled with an external mechanism, the distance between the control panel and the connector can be adjusted by the height of the protrusions 8. That is, when the mechanism panel is locked with the connector, the panel is pressed against the protrusions 8 after contacting them, so that the panel can no longer move forward, thus accurately ensuring the distance between the panel and the connector.

[0055] In addition, by providing a groove 5 at one end of the flat structure of the hardware terminal 3 to reduce the surface volume of the hardware terminal 3, the stability of the overall structure is improved, the contact resistance between the hardware terminal 3 and the conductor 7 is reduced, thereby improving the stability and reliability of signal transmission, helping to maintain consistent spacing between the hardware terminals 3, avoiding signal crosstalk or electromagnetic interference, and improving electrical performance.

[0056] The junction between the flat end of the hardware terminal 3 and the conductor 7 is arranged in an unfolded shape. The unfolded shape provides a structure with varying widths, which helps to reduce the inductance of the circuit, thereby improving the signal transmission quality. The narrower setting can shorten the length of the current loop, reduce electromagnetic interference (EMI) and radio frequency interference (RFI), reduce impedance, improve grounding stability, and help ensure signal integrity and reliable operation of the equipment.

[0057] The assembly process of this utility model is as follows: After the metal shell 1, metal terminal 3 and harpoon-shaped hardware 4 of this product are stamped into shape by stamping, the metal shell 1, plastic body 2 and harpoon-shaped hardware 4 are riveted together by metal rivets 6. Then, the metal terminal 3 is inserted into the plastic body 2 and the plastic plug is inserted into the plastic body 2 to fix the metal terminal 3. In addition to punching a hole for fixing the metal rivet 6 on each side of the metal shell 1, there are also two protrusions 8 punched on each side. The height of the protrusions 8 can be adjusted according to the actual needs.

[0058] like Figure 14 As shown, the production process of this utility model is as follows:

[0059] The manufacturing process for VGA male connectors includes the following steps:

[0060] Step 1, stamping pressure: stamp the hardware terminal 3, hardware housing 1 and harpoon-shaped hardware 4 respectively, and control the quality requirements through inspection.

[0061] The second step is external electroplating: the stamped metal terminal 3, the metal housing 1 and the harpoon-shaped metal parts 4 are subjected to external electroplating surface treatment.

[0062] The third step is inspection: inspection ensures that the quality of the electroplated products meets the product requirements.

[0063] The fourth step is to assemble the metal casing, harpoon-shaped hardware, and plastic body: the metal casing 1, harpoon-shaped hardware 4, and plastic body 2 are riveted together using 6 metal rivets; the metal casing 1, harpoon-shaped hardware 4, and plastic body 2 have holes on both sides for fixing the 6 metal rivets, and then the quality is controlled by inspection.

[0064] Step 5: Assemble the hardware terminals and plastic back cover: Insert the hardware terminals 3 into the holes in the plastic body 2 specifically for fixing the hardware terminals 3, and install the plastic back cover 11 onto the plastic body 2 to prevent the hardware terminals 3 from shaking inside the plastic body 2. The plastic body 2 has fastening points for fixing the plastic back cover 11 to ensure that the plastic back cover 11 and the plastic body 2 are tightly fastened to reduce the probability of falling off. This step is inspected to ensure quality requirements.

It should not be construed that the specific implementation of the present invention is limited to these descriptions.
