Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic equipment, in particular to a connector and an accessory of electronic equipment. BACKGROUND

[0002] In the connection of electronic equipment, the design of the conventional connector welding structure often arranges the ground pins and the power supply pins on both sides of the high-frequency signal pins. Although this design simplifies the layout and welding process of the connector to a certain extent, its high-frequency shielding effect is particularly insufficient in the environment of high-frequency signal transmission.

[0003] In the process of high-frequency signal transmission, the connector needs to have good shielding performance to reduce the influence of external electromagnetic interference (EMI) and radio frequency interference (RFI) on signal transmission. However, in the conventional connector welding structure, due to the arrangement mode of the ground pins and the power supply pins, the electromagnetic environment around the high-frequency signal pins becomes complex. The ground pins and the power supply pins may generate unnecessary electromagnetic radiation and interference in the process of high-frequency signal transmission, thereby affecting the signal transmission quality of the high-frequency signal pins.

[0004] Specifically, when high-frequency signals are transmitted through the pins (PINs), if the surrounding electromagnetic environment is unstable, it may cause signal attenuation, distortion or even loss. However, in the conventional connector welding structure, due to the interference of the ground pins and the power supply pins, the electromagnetic environment around the high-frequency signal pins is often difficult to maintain stable.

[0056] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0057] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplifying the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed.

[0058] For ease of description, spatial relative terms can be used herein to describe the positional relationship or movement of one element or feature relative to another element or feature as shown in the drawings, such as "inner", "outer", "inside", "outside", "below", "under", "above", "on", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over or reversed, or the device is moved or rotated, the indicative directions will also change accordingly, for example: the element described as "below" or "under" other elements or features will be subsequently oriented as "above" or "above" other elements or features. Therefore, the example term "under" can include both up and down positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used herein are interpreted accordingly.

[0059] In some example embodiments, a connector applied to an electronic device can realize stable transmission and efficient connection of internal signals. The electronic device is internally configured with various necessary accessories such as circuit boards and connectors to ensure normal operation of the device. The connector is assembled and connected with the circuit board to realize transmission. Alternatively, the connector is plugged with another connector in the electronic device to realize signal transmission.

[0060] As shown in Figures 1-7 The present application provides a connector, which includes a shielding member 1 and a terminal assembly 2, and the shielding member 1 is provided with a plurality of first shielding groups 11 and a plurality of second shielding groups 12. The terminal assembly 2 includes a plurality of ground terminal groups 21, wherein the plurality of ground terminal groups 21 correspond to and are welded to part of the plurality of first shielding groups 11 one by one, the plurality of ground terminal groups 21 correspond to the plurality of second shielding groups 12 one by one, and the second shielding groups 12 elastically abut against another part of the ground terminal groups 21.

[0061] The shielding member 1 can reduce the influence of external electromagnetic interference on the signal transmission inside the connector, thereby improving the electromagnetic compatibility and overall performance of the connector. The ground terminal group 21 is connected to the shielding member 1, which can provide a low-impedance path to quickly guide static electricity to the ground, preventing static electricity accumulation from damaging the internal circuit of the connector. In addition, the welding connection between the ground terminal group 21 and the shielding member 1 provides a stable low-impedance path, ensuring the reliability of the electrical connection between the shielding member 1 and the ground terminal group 21, especially in high-frequency signal transmission or high electromagnetic interference environments, welding can effectively reduce signal interference; the elastic abutment of the shielding member 1 to the ground terminal group 21 realizes contact, which can adapt to certain mechanical deformation and vibration, increasing the flexibility and vibration resistance of the connection.

[0062] In some embodiments, the first shielding group 11 is welded to the ground terminal group 21 in the first direction, and the second shielding group 12 elastically abuts the ground terminal group 21 in the second direction. The first direction is the thickness direction of the connector, and the second direction is perpendicular to the first direction, which is the insertion direction of the connector. By fixing the connection between the ground terminal group 21 and the shielding member 1 in the first direction, the stability of the connection between them is ensured; by elastically abutting the ground terminal group 21 with the shielding member 1 in the second direction, a certain buffering effect is provided during insertion. The elastic abutment can also dynamically adjust the contact pressure to ensure the stability of signal transmission.

[0063] In some embodiments, the ground terminal group 21 includes a first ground terminal 211 and a second ground terminal 212, which are arranged on both sides of the shielding member 1 along the first direction. When the first ground terminal 211 and the second ground terminal 212 are arranged on both sides of the shielding member 1, the formation of a ground loop can be effectively avoided. If the shielding member 1 is only grounded at one end, it may cause a voltage to be induced on the shielding member 1, thereby forming an antenna effect and interfering with signal transmission. Two-sided grounding can prevent the accumulation of induced voltage and reduce electromagnetic interference.

[0068] In some embodiments, the first shielding protrusion 111 and the second shielding protrusion 112 are symmetrical structures, which can effectively balance the stress generated during welding, minimizing welding deformation. By arranging symmetrical first shielding protrusions 111 and second shielding protrusions 112 on both sides of the shielding 1 along the first direction, the welding stress can be offset, thereby maintaining the stability of the overall structure of the shielding 1. In addition, symmetrical welding points can provide more uniform mechanical support, enhancing the strength and reliability of the welding joint.

[0069] In some embodiments, the first shielding contact 121 and the second shielding contact 122 are symmetrical structures, the symmetrical first shielding contact 121 and the second shielding contact 122 can ensure that a stable low-impedance path is formed between the shielding member 1 and the ground terminal group 21, thereby effectively reducing the propagation path of electromagnetic interference, and can also balance mechanical stress and reduce structural deformation caused by asymmetric stress.

[0070] In some embodiments, the first shielding protrusion 111 includes a shielding platform 1111 and at least two shielding feet 1112, the shielding feet 1112 connecting the shielding platform 1111 and the shielding member 1; wherein the shielding platform 1111 is welded with the ground terminal group 21.

The provision of the arc-shaped arm 1212 can provide a stable elastic abutting force, ensure that the shielding member 1 and the ground terminal group 21 always maintain good electrical contact, and also effectively reduce poor contact caused by mechanical vibration, thermal expansion or plugging operation.

[0072] In some embodiments, the connecting arm 1211 and the shielding member 1 are connected through a rounded transition, effectively dispersing stress and reducing the risk of breakage caused by mechanical stress or impact.
