Description

Electrical connectors, electrical connection devices and electronic equipment Technical Field

[0001] This disclosure relates to the field of electrical connection technology, and in particular to an electrical connector, an electrical connection device, and an electronic device. Background Technology

[0002] Currently, wearable devices (wrist-worn devices, neck-worn devices, etc.), mobile communication devices (mobile phones, tablets, etc.), and mobile platforms (unmanned aerial vehicles, unmanned vehicles, etc.) have become indispensable technological products in people's lives. In order to reduce manufacturing difficulty and improve assembly efficiency, electronic devices usually use electrical connection devices containing male and female connectors to connect different electronic components (such as between different circuit boards, or between a circuit board and different electronic components).

[0003] In related technologies, to reduce the interference of electromagnetic radiation on other electronic devices and / or improve electromagnetic interference immunity, an electromagnetic shielding structure needs to be constructed around the electrical connection device. This prevents electromagnetic radiation of different frequency bands generated by antennas and other devices from interfering with the internal operation of the connector. However, the electromagnetic shielding performance of traditional electromagnetic shielding structures for electrical connections is not ideal, which is detrimental to improving the reliability of electronic equipment. Summary of the Invention

The connecting assembly includes an insulating member and conductive terminals fixedly disposed on the insulating member. The insulating member passes through the clearance notches and is fixedly connected to the shielding covers, such that at least a portion of the conductive terminals is disposed within the electromagnetic shielding cavity. The conductive terminals are insulated from the electromagnetic shielding shell.

[0007] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0008] This electrical connector can be used in male or female connectors. When in use, the conductive parts of other connectors are inserted into the electromagnetic shielding cavity and make electrical contact with the conductive terminals of this connector. At this time, the connector can shield against electromagnetic radiation generated by the conductive parts and terminals being energized through the shielding frame. Simultaneously, by fixing the shielding cover to the shielding frame, the shielding area at the bottom of the electromagnetic shielding cavity can be increased, thereby improving the electromagnetic shielding performance of the connector.

[0009] The technical solution of this disclosure will be further explained below:

[0010] In one embodiment, the electromagnetic shielding shell further includes an isolation terminal, which is fixedly connected to the shielding cover and extends toward the clearance notch.

[0014] In one embodiment, the shielding cover is snapped into the insulating component.

[0015] In one embodiment, the shielding cover and the insulating member are provided with a locking part and a buckle part that engages with the locking part.

[0016] In one embodiment, the shielding cover protrudes into the electromagnetic shielding cavity to form a locking portion, which has a locking groove. A snap-fit ​​portion is disposed on the insulating member and forms a protrusion that engages with the locking groove.

[0017] In one embodiment, the card part is further provided with a hook, which is inserted into the card slot, and the protrusion is provided with a mating groove that engages with the hook.

[0018] In one embodiment, the electrical connector is a female connector, and the card portion and the inner sidewall of the shielding frame are spaced apart to form a first clamping groove.

[0019] Alternatively, the electrical connector is a male connector, with the card portion and the inner sidewall of the shielding frame spaced apart to form a first limiting portion.

[0025] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0026] In use, the conductive terminals of the male connector are inserted into the electromagnetic shielding cavity of the female connector and make electrical contact with the conductive terminals of the female connector. The conductive terminals of the female connector are also inserted into the electromagnetic shielding cavity of the male connector. At this time, when electromagnetic radiation is generated by energizing the conductive components and terminals, the shielding frames of the male and female connectors work together to shield the electromagnetic radiation from spreading outwards. Simultaneously, the shielding cover is fixedly connected to the shielding frame, and the shielding covers of the male and female connectors at least increase the shielding area at the bottom of the electromagnetic shielding cavity of the female connector, reducing the diffusion of electromagnetic radiation to the outside of the electrical connection device, thereby improving the electromagnetic shielding performance of the electrical connection device.

[0027] The technical solution of this disclosure will be further explained below:

[0028] In one embodiment, the electromagnetic shielding shell further includes an isolation terminal, which is fixedly connected to the shielding cover and extends toward the clearance notch; when the conductive terminal of the male connector is electrically connected to the conductive terminal of the female connector, the isolation terminal of the male connector is electrically in contact with the isolation terminal of the female connector.

[0029] In one embodiment, at least a portion of the isolation terminal of the female connector is bent into an elastic portion; when the conductive terminal of the male connector is electrically connected to the conductive terminal of the female connector, the elastic portion elastically abuts against the isolation terminal of the male connector.

[0030] In one embodiment, the shielding frame of the female connector has a flange disposed outside the electromagnetic shielding cavity, and the flange and the shielding cover are spaced apart along the depth direction of the electromagnetic shielding cavity.

Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0049] Wearable devices (wrist-worn devices, neck-worn devices, etc.), mobile communication devices (mobile phones, tablets, etc.), and mobile platforms (unmanned aerial vehicles, unmanned vehicles, etc.) have become indispensable technological products in people's lives. However, with so many types and brands of electronic devices available, how to win people's favor and enhance product competitiveness has become an increasingly important issue for electronic device manufacturers.

[0050] Currently, in order to reduce manufacturing difficulty and improve assembly efficiency, electronic devices typically use electrical connection devices that include male and female connectors to connect different electronic components (e.g., between different circuit boards, or between a circuit board and different electronic components).

[0051] In related technologies, to reduce the interference of electromagnetic radiation on other electronic devices and / or improve electromagnetic interference immunity, a shielding structure needs to be constructed around the electrical connection device. For example, this prevents electromagnetic radiation of different frequency bands generated by antennas and other devices from interfering with the operation of the antenna's electrical connection device. However, the electromagnetic shielding structure of traditional electrical connection devices requires the use of conductive terminals to realize the shielding shell of the male connector, resulting in a small shielding area and unsatisfactory electromagnetic shielding performance, which is detrimental to improving the reliability of electronic equipment.

[0052] Therefore, it is necessary to provide an electrical connector. This electrical connector has a large shielding area, which can effectively improve the electromagnetic shielding performance of the electrical connection device. This, in turn, can improve the reliability of electronic devices using this electrical connection device.

[0053] To better understand the electrical connectors of this disclosure, the following description is provided with reference to the accompanying drawings.

[0054] As shown in Figures 1 to 3, an electrical connector 100 is provided, including an electromagnetic shielding shell 110 and a connecting assembly 120. The electromagnetic shielding shell 110 includes a shielding frame 112 surrounding an electromagnetic shielding cavity 111 and a shielding cover 113 fixedly connected to the shielding frame 112. Two shielding covers 113 are spaced apart on opposite sides of the shielding frame 112 to form clearance notches 114 communicating with the electromagnetic shielding cavity 111. The connecting assembly 120 includes an insulating member 121 and conductive terminals 122 fixedly disposed on the insulating member 121. The insulating member 121 passes through the clearance notch 114 and is fixedly connected to the shielding cover 113, such that at least a portion of the conductive terminals 122 is disposed within the electromagnetic shielding cavity 111. The conductive terminals 122 are insulated from the electromagnetic shielding shell 110.

[0055] The electrical connector 100 can be used in either the male connector 210 or the female connector 220. When in use, the conductive parts of other connectors are inserted into the electromagnetic shielding cavity 111 and make electrical contact with the conductive terminals 122 of the electrical connector 100. At this time, the electrical connector 100 can shield the electromagnetic radiation generated by the energization between the conductive parts and the conductive terminals 122 through the shielding frame 112. Simultaneously, by fixing the shielding cover 113 to the shielding frame 112, the shielding area at the bottom of the electromagnetic shielding cavity 111 can be increased, thereby improving the electromagnetic shielding performance of the electrical connector 100.

[0056] As shown in Figures 1 to 3, the electromagnetic shielding structure of a conventional electrical connection device 200 requires the integration of isolation terminals 115 on the insulating member 121 to achieve shielding connections between shielding shells. This increases the difficulty of arranging the conductive terminals 122 on the insulating member 121, increases the overall volume of the connection assembly 120, and consequently makes the electrical connector 100 larger. However, in some embodiments of this disclosure, the electromagnetic shielding shell 110 further includes isolation terminals 115, which are fixedly connected to the shielding cover 113 and extend towards the clearance notch 114. Thus, when the electrical connector 100 is in use, the conductive members of other connectors are inserted into the electromagnetic shielding cavity 111 and make electrical contact with the conductive terminals 122 of the electrical connector 100. In this case, the shielding connection between the isolation terminals 115 and the shielding structures of other connectors improves the shielding performance against electromagnetic radiation generated by the conductive members and conductive terminals 122 being energized. Meanwhile, the isolation terminal 115 on the electromagnetic shielding shell 110 can effectively reduce the manufacturing difficulty of the connection component 120, making the structure of the electrical connector 100 more compact, adapting to the miniaturization design needs of the electrical connector 100, and reducing the space occupied by the electronic device 10.

[0057] As shown in Figures 2 and 3, in some embodiments, at least a portion of the isolation terminal 115 is bent into an elastic portion 1151, and the insulating member 121 is provided with a relief groove 1211 to avoid the elastic portion 1151, with a portion of the elastic portion 1151 inserted into the relief groove 1211. Thus, by providing the elastic portion 1151, the isolation terminal 115 can elastically abut against other isolation structures, improving the reliability of the shielding connection. The relief groove 1211 ensures that the insulating member 121 does not interfere with the elastic deformation of the elastic portion 1151.

[0058] Optionally, in some embodiments, the shielding frame 112, the shielding cover 113, and the isolation terminal 115 are integrally formed. This reduces assembly steps and improves the production efficiency of the electromagnetic shielding shell 110.

[0059] It should be noted that there are various ways to achieve the integral molding of the shielding frame 112, shielding cover 113 and isolation terminal 115, including but not limited to die casting, stamping, etc.

[0060] For example, in some embodiments, the shielding frame 112 and the shielding cover 113 are drawn together, and the isolation terminal 115 is bent and connected to the shielding cover 113. Thus, the electromagnetic shielding shell 110 can be easily integrally formed using sheet metal parts, effectively improving production efficiency. Furthermore, a thinner electromagnetic shielding shell 110 can be obtained, effectively reducing the size of the electrical connector 100.

[0061] It should be noted that there are various ways to fix the electromagnetic shielding shell 110 and the connecting component 120, including but not limited to snap-fit ​​fixing, screw fixing, adhesive fixing, etc.

[0062] As shown in Figures 1 to 3, in some embodiments, the shielding cover 113 and the insulating component 121 are snap-fitted together. Thus, the snap-fit ​​connection between the shielding cover 113 and the insulating component 121 facilitates the fixing of the connecting assembly 120 onto the electromagnetic shielding shell 110, making assembly and disassembly convenient.

[0063] Optionally, in some embodiments, the shielding cover 113 and the insulating member 121 are provided with a locking portion 1131 and a latching portion 1212 that engages with the locking portion 1131. The latching connection between the locking portion 1131 and the latching portion 1212 facilitates the fixing of the insulating member 121 onto the electromagnetic shielding shell 110, enabling the electromagnetic shielding shell 110 to shield the electromagnetic radiation generated by the conductive terminal 122.

[0064] As shown in Figures 2 and 3, in some embodiments, the shielding cover 113 protrudes into the electromagnetic shielding cavity 111 to form a locking portion 1131, which has a locking groove 1132. This reduces the manufacturing difficulty of the electromagnetic shielding shell 110. A snap-fit ​​portion 1212 is provided on the insulating member 121 and forms a protrusion that engages with the locking groove 1132. Thus, through the snap-fit ​​engagement of the locking groove 1132 and the protrusion, the insulating member 121 is easily fixed to the electromagnetic shielding shell 110, facilitating the use of the electromagnetic shielding shell 110 to shield the electromagnetic radiation generated by the conductive terminal 122.

[0065] As shown in Figures 2 and 3, in some embodiments, the locking part 1131 is further provided with a locking hook 1133, which is inserted into the locking groove 1132. The protrusion is provided with a mating groove 1213 that engages with the locking hook 1133. In this way, by utilizing the engagement between the locking hook 1133 and the mating groove 1213, the connection between the insulating component 121 and the electromagnetic shielding shell 110 is further improved, making it less prone to separation and enhancing the reliability of the electrical connector 100.

[0066] As shown in Figure 1, in some embodiments, the electrical connector 100 is a male connector 210, and the locking portion 1131 and the inner sidewall of the shielding frame 112 are spaced apart to form a first limiting portion 117. In this way, the first limiting portion 117 can be used to clamp and cooperate with the female connector 220, so that the female connector 220 and the male connector 210 are firmly fixed and the electrical connection is stable.

[0067] As shown in Figure 2, in some embodiments, the electrical connector 100 is a female connector 220, and the locking portion 1131 and the inner sidewall of the shielding frame 112 are spaced apart to form a first clamping groove 116. In this way, the first clamping groove 116 can be used to clamp the male connector 210, so that the female connector 220 and the male connector 210 are firmly fixed and the electrical connection is stable.

[0068] As shown in Figures 2 and 3, in some embodiments, the electrical connector 100 is a female connector 220, and the shielding frame 112 has a flange 1121 disposed outside the electromagnetic shielding cavity 111. The flange 1121 and the shielding cover 113 are spaced apart along the depth direction of the electromagnetic shielding cavity 111. In this way, the electromagnetic shielding performance of the electrical connector 100 can be further improved by using the flange 1121.

[0069] For example, when the female connector 220 is connected to the male connector 210, the flange 1121 can cover the solder part of the male connector 210.

[0070] As shown in Figure 1, in some embodiments, a portion of the conductive terminal 122 is exposed through the clearance notch 114. This facilitates the soldering and fixing of the conductive terminal 122 to the pads of other electronic components 300 via the clearance notch 114. For example, the conductive terminal 122 is soldered and fixed to pads on a circuit board.

[0071] As shown in Figure 2, in some embodiments, the insulating member 121 includes at least two protrusions 1214 spaced apart on two opposite sides of the shielding frame 112. A second clamping groove 1215 is formed between two adjacent protrusions 1214. A third clamping groove 101 is formed between the outermost protrusion 1214 on the insulating member 121 and the inner sidewall of the shielding frame 112. At least a portion of the conductive terminal 122 is exposed in the second clamping groove 1215 and / or the protrusions 1214. This facilitates the use of the second clamping groove 1215 and the third clamping groove 101 to clamp the protrusion of the male connector 210, achieving a secure connection between the female connector 220 and the male connector 210, and ensuring a reliable electrical connection between the conductive terminals 122 of the female connector 220 and the conductive terminals 122 of the male connector 210.

[0072] As shown in Figures 4 and 5, in some embodiments, an electrical connection device 200 is also provided, including the electrical connector 100 in any of the above embodiments. The electrical connector 100 includes two connectors: a male connector 210 and a female connector 220 detachably connected to the male connector 210. When the conductive terminal 122 of the male connector 210 is electrically connected to the conductive terminal 122 of the female connector 220, the electromagnetic shielding shell 110 of the male connector is inserted into the electromagnetic shielding cavity 111 of the female connector 220, and the isolation terminal 115 of the male connector 210 is in electrical contact with the isolation terminal 115 of the female connector 220.

[0073] When the electrical connection device 200 is in use, the conductive terminal 122 of the male connector 210 is inserted into the electromagnetic shielding cavity 111 of the female connector 220 and makes electrical contact with the conductive terminal 122 of the female connector 220. The conductive terminal 122 of the female connector is also inserted into the electromagnetic shielding cavity 111 of the male connector 210. At this time, when electromagnetic radiation is generated by the conductive components and conductive terminals 122 being energized, the shielding frames 112 of both the male and female connectors can shield the electromagnetic radiation from spreading outwards. Simultaneously, the shielding cover 113 is fixedly connected to the shielding frame 112, and the shielding cover 113 of the male connector 210 and the shielding cover 113 of the female connector 220 are positioned opposite each other. This increases the shielding area at the bottom and top of the electromagnetic shielding cavity 111, reducing the diffusion of electromagnetic radiation to the outside of the electrical connection device 200, thereby improving the electromagnetic shielding performance of the electrical connection device 200.

[0074] As shown in Figures 4 and 5, in some embodiments, the electromagnetic shielding shell 110 further includes an isolation terminal 115. The isolation terminal 115 is fixedly connected to the shielding cover 113 and extends towards the clearance notch 114. When the conductive terminal 122 of the male connector 210 is electrically connected to the conductive terminal 122 of the female connector 220, the isolation terminal 115 of the male connector 210 is electrically in contact with the isolation terminal 115 of the female connector 220. Thus, when the electrical connection device 200 is in use, the conductive terminal 122 of the male connector 210 is inserted into the electromagnetic shielding cavity 111 of the female connector 220 and is electrically in contact with the conductive terminal 122 of the female connector 220. At this time, the isolation terminal 115 of the male connector 210 and the isolation terminal 115 of the female connector 220 are shielded together, so that the electromagnetic shielding shell 110 of the male connector 210 and the electromagnetic shielding shell 110 of the female connector 220 are connected as a whole, which can effectively improve the electromagnetic shielding performance of the electrical connection device 200. Meanwhile, the placement of isolation terminals 115 on the electromagnetic shielding shell 110 effectively reduces the manufacturing difficulty of the connection component 120, making the electrical connection device 200 more compact and tightly fitted. This adapts to the miniaturization design requirements of the electrical connection device 200 and reduces the space occupied inside the electronic device 10.

[0075] As shown in Figures 3 to 6, in some embodiments, at least a portion of the isolation terminal 115 of the female connector 220 is bent into an elastic portion 1151; when the conductive terminal 122 of the male connector 210 is electrically connected to the conductive terminal 122 of the female connector 220, the elastic portion 1151 elastically abuts against the isolation terminal 115 of the male connector 210. Thus, by providing the elastic portion 1151, the elastic abutment between the isolation terminal 115 of the female connector 220 and the isolation terminal 115 of the male connector 210 can be achieved, improving the reliability of the shielded connection.

[0076] As shown in Figures 4 to 6, in some embodiments, the shielding frame 112 of the female connector 220 is provided with a flange 1121 disposed outside the electromagnetic shielding cavity 111. The flange 1121 and the shielding cover 113 are spaced apart along the depth direction of the electromagnetic shielding cavity 111, and the conductive terminal 122 of the male connector 210 is provided with a soldering part. When the female connector 220 and the male connector 210 are connected, the flange 1121 can cover the soldering part. In this way, the electromagnetic shielding performance of the electrical connection device 200 can be further improved by using the flange 1121.

[0077] Optionally, in some embodiments, the shielding cover 113 of the male connector 210 and the shielding cover 113 of the female connector 220 are disposed opposite each other along the depth direction of the electromagnetic shielding cavity 111. This increases the shielding area at the bottom and top of the electromagnetic shielding cavity 111, reduces the diffusion of electromagnetic radiation to the outside of the electrical connection device 200, and thereby improves the electromagnetic shielding performance of the electrical connection device 200.

[0078] As shown in Figures 4 to 6, in some embodiments, the locking portion 1131 of the female connector 220 and the inner sidewall of its shielding frame 112 are spaced apart to form a first clamping groove 116. The locking portion 1131 of the male connector 210 and the inner sidewall of its shielding frame 112 are spaced apart to form a first limiting portion 117. This facilitates the use of the first clamping groove 116 to clamp the first limiting portion 117, ensuring a secure fixation between the female connector 220 and the male connector 210 and a stable electrical connection.

[0079] Optionally, in some embodiments, the electrical connection device 200 includes a board-to-board electrical connection device 200.

[0080] As shown in Figure 7, in some embodiments, an electronic device 10 is also provided, including at least two electronic devices 300 and an electrical connection device 200 in any of the above embodiments. One of the two electronic devices 300 is provided with a male connector 210, and the other is provided with a female connector 220 that is electrically connected and mated with the male connector 210.

[0081] The electronic device 10 uses the electrical connection device 200 in any of the above embodiments, which has good electromagnetic shielding performance, reduces the impact of electromagnetic radiation on the electronic device 300, and improves the reliability of the electronic device 10.

[0082] For example, as shown in Figure 7, in some embodiments, one electronic device 300 is a control motherboard 310, another is a flexible circuit board 320, and yet another is a radio frequency circuit board 330. One end of the control motherboard 310 and the flexible circuit board 320 are electrically connected via a set of electrical connection devices 200, and the other end of the radio frequency circuit board 330 and the flexible circuit board 320 are electrically connected via another set of electrical connection devices 200. Thus, due to the good electromagnetic shielding performance of the electrical connection devices 200, the impact of electromagnetic radiation of different frequency bands generated by other electronic devices 300 on antenna performance can be effectively reduced.

[0083] The electronic device 10 may include handheld devices, in-vehicle devices, wearable devices, monitoring devices, cellular phones, smartphones, personal digital assistants (PDAs), tablet computers, laptops, laptop computers, cameras, video recorders, cameras, smartwatches, smart bracelets, in-vehicle computers, and other electronic devices with imaging capabilities.
