Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of VGA interface, in particular to a connector. Background Art
[0002] In modern electronic devices, connectors are key interconnect components, and their design and manufacturing quality directly affect the overall performance and reliability of the device. In particular, as a widely used standard interface, the stable connection between the video graphics array (VGA) connector and the printed circuit board (PBA) is crucial to ensure clear and distortion-free video signal transmission.
[0003] However, in the actual production process, the welding process of VGA connector and PBA often encounters the problem of unstable placement, resulting in poor welding quality, which is specifically manifested as follows:
[0004] Limited connector positioning accuracy: Traditional VGA connectors are usually composed of a mounting shell, a VGA female connector, a mounting seat, and a plug-in. Although the mounting seat is provided with a mounting groove to accommodate the VGA female connector, and the mounting shell is provided with a mounting opening for the end of the VGA female connector with a jack to pass through, when welding with the PBA, due to the lack of an accurate and efficient positioning mechanism, the connector is prone to slight offset during the placement stage before welding, and it is impossible to ensure that the connection terminals of the VGA female connector are accurately aligned with the corresponding pads on the PBA, thus affecting the welding effect.
[0005] Poor welding stability: In the existing VGA connector design, the plug-in usually includes two inserts spaced along a specific direction (first direction) for plugging and mating with the corresponding positioning holes on the PBA. Although these inserts help to stabilize the connection of the connector in the working state, they do not directly participate in fixing the position of the connector during the welding stage. The constraint system formed by the PBA and the inserts does not effectively prevent the connector from shaking in a direction perpendicular to the first direction (second direction), which leads to unstable connector position during welding.
[0006] Such unstable placement problems will not only cause welding defects, such as cold solder joints, false solder joints, cold solder joints, etc., affecting the reliability of electrical connections and signal transmission quality, but will also lead to increased repair rates and increased production costs. In serious cases, it may even lead to product recalls, damaging the manufacturer's economic interests and brand image. Although the prior art has attempted to improve welding quality by improving welding process parameters, using special welding materials, or optimizing clamping tools, these measures have not fundamentally solved the problem of unstable placement caused by structural design when the VGA connector is butt-welded with the PBA.
[0007] In view of this, the utility model proposes an innovative connector structure design to solve the problems of unstable placement and poor welding quality caused by the structural design of the existing VGA connector when welding with the PBA. The design optimizes the configuration relationship between the mounting seat, the connector and the positioning part, and introduces a new stabilization mechanism to achieve accurate positioning and efficient fixation of the VGA connector and the PBA during butt welding, significantly improve the welding quality, and ensure the high performance and high reliability of the electronic equipment.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.
[0033] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.
[0034] In order to solve the problem that the welding process of the VGA connector and the PBA often encounters the problem of unstable placement during the actual production process, resulting in the problem of low welding quality, an embodiment of the utility model provides a connector.
[0035] like Figure 1-3As shown, a connector provided by an embodiment of the utility model comprises a mounting shell 1, a VGA mounting seat 2, a female connector 3 and a plug-in component 4, wherein the mounting seat 2 is arranged on the inner side of the mounting shell 1 and has a mounting groove 21, a mounting opening 11 is provided on the mounting shell 1, the VGA female connector is installed in the mounting groove 21 and one end thereof having a plug hole 31 is passed through the mounting opening 11, the plug-in component 4 comprises two plug-in pieces 41 arranged at intervals along a first direction, the two plug-in pieces 41 are connected to the mounting seat 2 and extend in a direction opposite to the opening of the plug hole 31, the mounting shell 1 has two positioning portions 12 arranged at intervals in a second direction, the positioning portions 12 extend in the same direction as the plug-in pieces 41, the second direction is perpendicular to the first direction, and the two positioning portions 12 and the two plug-in pieces 41 are arranged around the VGA female connector 3.
[0036] With such arrangement, the two inserts 41 cooperate with the two positioning portions 12 in the first and second directions perpendicular to each other, and can be positioned accurately when the connector is installed on the soldering pad of the PBA, thereby solving the problem of unstable placement often encountered in the soldering process of the VGA connector and the PBA.
[0037] refer to Figure 3 As best shown in FIG. 1 , in this embodiment, the plug connector 4 includes a connection seat 42, and the plug piece 41 is connected to the mounting shell 1 through the connection seat 42. The mounting seat 42 can generally be provided with a mounting hole, and the connector can be inserted into the mounting hole, thereby achieving a tight connection between the plug connector and the mounting seat 2. Optionally, the plug piece 41 and the connection seat 42 are integrally formed.
[0038] Furthermore, the insert 41 is provided with a snap-in groove 411, and the opening direction of the snap-in groove 411 is opposite to the opening direction of the jack 31. When the connector is mounted on the pad of the PBA, a positioning piece that matches the snap-in groove 411 is usually provided on the pad, and the positioning piece can be plugged into the snap-in groove, thereby completing the pre-positioning of the connector relative to the PBA pad, which helps to improve the positioning accuracy of the connector.
[0039] In this embodiment, two positioning portions 12 are arranged at intervals along the second direction, and further, each positioning portion 12 includes at least two positioning pieces 121 arranged at intervals along the first direction. It can be understood that the plurality of positioning pieces 121 form an array in the first direction and the second direction, so that the mounting shell can be accurately positioned on the pad of the PBA, and the mounting seat and the VGA female connector are arranged on the mounting shell 1, so as to ensure that the VGA female connector can be further accurately positioned at the appropriate position on the PBA pad.
[0040] It should be noted that, in the present invention, the VGA female connector 3 also includes a plurality of connection terminals 32, each connection terminal 32 is correspondingly arranged in one of the jacks 31, the connection terminal 32 extends along the opening direction opposite to the jack 31 and protrudes out of the mounting base 2, and a plurality of the positioning pieces 121 and the two inserting pieces 41 are arranged around the connection terminal 32, which plays a certain protective role for the connection terminal and can assist in positioning the connection terminal 32 to a predetermined position on the PBA pad.
[0041] Further, refer to Figure 2 As shown, the mounting seat 2 has a mounting surface facing away from the opening direction of the jack 31, and a plurality of supporting bosses 22 are provided on the mounting seat. The side of the supporting bosses 22 away from the mounting surface forms a fitting surface for abutting against a mounting member (such as a PBA). The fitting surface abuts against the mounting surface of the PBA, so that the position of the connector and the PBA can be relatively fixed to avoid displacement.
[0042] There is a gap between any two connected support bosses 22. When the connector is soldered to the PBA, the generated molten metal solder residue can be shaken off through the gap to prevent this part of the metal residue from remaining between the VGA female plug and the PBA and causing a short circuit inside the connector.
[0043] Further, refer to Figure 3 As shown, the connector also includes an EMI spring finger 5. EMI spring finger (ElectromagneticInterference Finger) plays a key role in electromagnetic compatibility (EMC) in electronic equipment, and its main purpose is to reduce or suppress electromagnetic interference (Electromagnetic Interference, EMI). The specific role of EMI spring finger in different application scenarios can be summarized as follows:
[0044] Electromagnetic shielding: Blocking radiated interference: EMI shrapnel is usually made of conductive materials, such as copper, aluminum or plated metal, which can form a continuous conductive path and constitute an electromagnetic shielding barrier. When installed around the device interface (such as VGA interface, network port, etc.) or inside the chassis, the EMI shrapnel can effectively block the high-frequency electromagnetic energy generated inside from radiating outward, and prevent external electromagnetic interference from entering the device, thereby reducing the impact on device performance and electromagnetic pollution to the external environment.
[0045] Ground connection: Establish a low impedance path: The EMI shrapnel ensures that the current can flow smoothly into the earth through good contact with the device housing or ground plane, reducing the impedance of the ground loop. In this way, when electromagnetic interference currents are generated, they can be quickly introduced into the ground through the shrapnel instead of accumulating in the circuit or propagating through radiation, thereby effectively suppressing interference.
[0046] Electrical contact: Improved interface contact: In connector design, such as the connector structure described above, EMI springs can ensure good electrical contact between male and female connectors. The elasticity of the spring allows it to be in close contact with the male connector during the plugging process, reducing the increase in resistance, signal reflection or electromagnetic pulse emission caused by poor contact, which may cause electromagnetic interference.
[0047] Improve integrity: Enhance chassis sealing: In chassis applications, EMI shrapnel helps to tightly connect the chassis frame and side panels and other components into a whole, reducing gaps and the possibility of electromagnetic energy leaking from the joints. This integrated design is especially important for sensitive equipment, which can ensure the stability of the electromagnetic environment inside the equipment and prevent electromagnetic leakage from affecting the normal operation of the equipment itself or adjacent systems.
[0048] In the utility model, the EMI spring piece 5 is sleeved on the mounting opening 11 and connected to a side of the mounting shell 1 provided with the mounting opening. The EMI spring piece 5 has an abutment portion 51 extending away from the mounting shell 1. The abutment portion 51 is used to abut against the VGA male connector. The VGA male connector can be used to be plugged and matched with the VGA female connector 3.
[0049] Further, still refer to Figure 3 As shown, the EMI shrapnel 5 also includes two connecting portions 52 spaced apart in the first direction corresponding to the two plug-in sheets 41, the connecting portion 52, the mounting shell 1, the mounting seat 2 and the plug-in sheets corresponding to the connecting portion 52 have overlapping portions in a direction parallel to the jack opening, and the connecting portion 52, the mounting shell 1, the mounting seat and the overlapping portions of the plug-in sheets 41 corresponding to the connecting portions are sequentially connected through a connecting piece.
[0050] Furthermore, the connecting member is configured as a bolt 6 , the head 61 of the bolt abuts against the connecting portion 52 , and the screw 62 of the bolt sequentially penetrates the connecting portion 52 , the mounting shell 1 , the insert 41 and is threadedly connected with the insert 41 .
[0051] Preferably, each of the abutting portions 51 includes abutting pieces 511 symmetrically arranged on both sides of the connecting portion 52. In this way, the abutting pieces 511 located on both sides of the connecting portion 52 can better act on the VGA male plug that matches the VGA female plug.
[0052] In summary, the embodiments of the present invention achieve the following technical effects:
[0053] In the first and second directions perpendicular to each other, the two inserts 41 cooperate with the two positioning portions 12, and can be positioned accurately when the connector is installed on the pad of the PBA, thereby solving the problem of unstable placement often encountered in the welding process of the VGA connector and the PBA.
