[0043] Electrical connectors are electrical connections in electronic systems that are mechanically created to achieve connection between two systems while maintaining the separability of the system for ease of manufacturing, maintenance, upgrading and expansion. Electrical connectors are key components in electronic systems, and their design, manufacturing and application have a significant impact on the performance of the entire system. With the development of technology and the expansion of application areas, the market size and application scope of electrical connectors are also growing.

[0044] When connecting two systems, it is critical to determine the connection status of the electrical connector, which is essential to ensure the normal operation of the electronic device. However, the electrical connectors in the related art are usually difficult to provide feedback during electrical connection, and it is difficult to feedback the connection status of the electrical connector, which is prone to the problem of unsuccessful connection or even connection error, resulting in damage to the subsystem.

[0045] Based on this, an electrical connector is provided to obtain feedback of the electrical connection between the male connector and the female connector when the male connector and the female connector are connected, so as to judge the connection status of the two and determine whether the two are successfully connected. This can reduce the time waste caused by connection errors and the electrical damage caused by abnormal power supply due to connection errors.

[0046] Referring to Figures 1 and 2, Figure 1 is a schematic diagram of the structure of an electrical connector 10 in an embodiment of the present application. Figure 2 is a schematic diagram of the structure of the female connector 200 in the embodiment shown in Figure 1 after removing the second side wall. The electrical connector 10 of the present application includes a male connector 100 and a female connector 200, and the female connector 200 and the male connector 100 are plugged into each other, thereby realizing an electrical connection between a first electronic system connected to the female connector 200 and a second electronic system connected to the male connector 100.

[0047] The male connector 100 includes a plurality of first pins 110, and the female connector 200 includes a plurality of second pins 220 corresponding to the plurality of first pins 110. The plurality of first pins 110 of the male connector 100 are electrically connected to the respective components of the second electronic system, and the plurality of second pins 220 of the female connector 200 are electrically connected to the respective components of the second electronic system. In this way, the respective components of the first electronic system can be electrically connected to the respective components of the second electronic system through the male connector 100 and the female connector 200, thereby realizing the electrical connection between the first electronic system connected to the female connector 200 and the second electronic system connected to the male connector 100.

[0048] The second pin 220 includes a first sub-pin 221 and a second sub-pin 222, which are spaced apart from each other and electrically insulated from each other; a plug-in slot 210 for plugging the male connector 100 is defined between the first sub-pin 221 and the second sub-pin 222. The electrical connector 10 has a plug-in state, and when the electrical connector 10 is in the plug-in state, the male connector 100 is at least partially plugged into the plug-in slot 210, and the first pin 110 is electrically connected to the first sub-pin 221 and the second sub-pin 222 of the corresponding second pin 220, so that the first sub-pin 221 and the second sub-pin 222 can be electrically connected to each other through the first pin 110.

[0049] It can be understood that one of the first sub-pin 221 and the second sub-pin 222 can be set according to the needs to connect the electronic system that the female connector 200 needs to connect. If the first sub-pin 221 is selected to connect the electronic system, when the male connector 100 is plugged with the female connector 200, the electrical connection between the electronic system connected to the male connector 100 and the electronic system connected to the female connector 200 can be achieved through the electrical connection between the first pin 110 and the first sub-pin 221. Because when the male connector 100 and the female connector 200 are plugged, the first pin 110 is electrically connected between the first sub-pin 221 and the second sub-pin 222, and the first sub-pin 221 and the second sub-pin 222 are electrically conductive, then at this time, it can be determined whether the first pin 110 and the second pin 220 are connected correctly by detecting whether the second sub-pin 222 receives the electrical signal sent by the electronic system connected to the female connector 200. If an electrical signal is received from the electronic system connected to the female connector 200 , it means that the electrical signal is smoothly transmitted to the second sub-pin 222 through the first sub-pin 221 and the second pin 220 in sequence, thus indicating that the first sub-pin 221 and the second pin 220 are stably connected.

[0050] For the convenience of description in this application, the first sub-pin 221 is used for connecting the electronic system, and the second sub-pin 222 is used for detection. In fact, one of the first sub-pin 221 and the second sub-pin 222 can be used for connecting the electronic system, and the other can be used for detection. The selection can be made according to the actual situation without too much restriction.

[0051] In the electrical connector 10 of the present application, the male connector 100 is plugged into the plug slot 210 and connected with the female connector 200. The electrical connection between the male connector 100 and the female connector 200 is realized by abutting the corresponding first pin 110 and the second pin 220. At the same time, when the male connector 100 and the female connector 200 are relatively plugged, the first pin 110 is electrically connected between the first sub-pin 221 and the second sub-pin 222, so that the first sub-pin 221 and the second sub-pin 222 are electrically conductive. Then, by detecting the electrical signal received by one of the first sub-pin 221 and the second sub-pin 222, it is detected whether the corresponding first pin 110 and the second pin 220 are successfully electrically conductive. In this way, the present application can obtain feedback on the electrical connection between the male connector 100 and the female connector 200 when they are connected, judge the connection status of the two, and judge whether the two are successfully connected. Thereby, the time waste caused by connection errors and the electrical damage caused by abnormal power-on due to connection errors can be reduced.

[0052] In some embodiments, referring to FIG. 1 and FIG. 2 , the first sub-pin 221 and the second sub-pin 222 are arranged at intervals along the first direction F1, and the second pin 220 further includes a first lead portion 223 and a second lead portion 224. The first lead portion 223 and the second lead portion 224 are both arranged on the same side of the plug slot 210 along the first direction F1, and the first lead portion 223 and the second lead portion 224 are arranged at intervals along the second direction F2. One end of the first lead portion 223 extends out of the plug slot 210, and the other end is electrically connected to the first sub-pin 221. One end of the second lead portion 224 extends out of the plug slot 210, and the other end is electrically connected to the second sub-pin 222.

[0053] In this way, the first lead portion 223 is used to electrically connect the first sub-pin 221 to the outside. Specifically, one end of the first lead portion 223 is electrically connected to the first sub-pin 221, and the other end extends out of the plug slot 210, and is used to electrically connect to the corresponding device of the first electronic system. Correspondingly, one end of the second lead portion 224 is electrically connected to the second sub-pin 222, and the other end extends out of the plug slot 210, and is used to detect the electrical signal received by the second sub-pin 222, and determine whether the corresponding first pin 110 and second pin 220 are successfully electrically connected. At the same time, the first sub-pin 221 and the second sub-pin 222 are spaced apart from each other, and the corresponding first lead portion 223 and the second lead portion 224 are also spaced apart from each other, reducing the risk of the problem of accidental contact between the first sub-pin 221 and the second sub-pin 222, resulting in detection errors, which is conducive to improving the accuracy of detection.

[0054] In some embodiments, an electrical testing device or an electrical signal detection device can be connected to the second lead portion 224 to detect whether the second lead portion 224 or the second sub-pin 222 receives the same electrical signal as the first sub-pin 221, thereby determining whether the corresponding first sub-pin 221 is electrically connected normally to the corresponding first pin 110.

[0055] In some embodiments, the first pin 110 and the second pin 220 both adopt a metal spring structure. In this way, when the male connector 100 is connected to the female connector 200, the first pin 110 and the second pin 220 can provide elastic force toward each other, thereby increasing the contact strength between the first pin 110 and the second pin 220, thereby increasing the connection strength between the male connector 100 and the female connector 200.

[0056] In some embodiments, as shown in FIG. 2 , the second pin 220 further includes a middle portion 225, the middle portion 225 is electrically connected between the second sub-pin 222 and the second lead portion 224, and along the second direction F2, the size of the middle portion 225 is smaller than the size of the second sub-pin 222, and a slot is defined between the middle portion 225 and the second sub-pin 222, and the first lead portion 223 extends out of the plug slot 210 through the slot. It can be understood that the middle portion 225 and the second sub-pin 222 define an "L"-shaped slot, so that the first lead portion 223 extends out of the plug slot 210 from the "L"-shaped slot, and does not conflict with the second sub-lead and the second lead portion 224, which is conducive to the first sub-lead and the first lead portion 223 being spaced from the second sub-lead and the second lead portion 224, reducing the risk of conflict between the first sub-lead and the second sub-lead, and helping to improve the detection accuracy of the electrical connector 10.

[0057] In some embodiments, the first pin 110 includes a first connection portion 111 and a second connection portion 112, and the first connection portion 111 and the second connection portion 112 are arranged at intervals along the first direction F1. When the electrical connector 10 is in a plugged state, the first connection portion 111 abuts against the first sub-pin 221, and the second connection portion 112 abuts against the second sub-pin 222, and the first connection portion 111 and the second connection portion 112 are electrically connected. Thus, the first connection portion 111 and the second connection portion 112 of the first pin 110 are electrically connected to the first sub-pin 221 and the second sub-pin 222, respectively. In this way, the first pin 110 corresponding to the male connector 100 and the second pin 220 corresponding to the female connector 200 are connected, and the first sub-pin 221 and the second sub-pin 222 are electrically connected to each other through the first pin 110. Then, by detecting the electrical signal of the second sub-pin 222, it can be detected whether the first pin 110 corresponding to the male connector 100 and the second pin 220 corresponding to the female connector 200 are accurately connected.

[0058] The side of the first connection portion 111 facing the first sub-pin 221 is a plane, and the side of the first sub-pin 221 facing the first connection portion 111 is a plane, which is conducive to increasing the contact area between the first connection portion 111 and the first sub-pin 221, thereby facilitating the improvement of the point conduction efficiency. The side of the second connection portion 112 facing the second sub-pin 222 is a plane, and the side of the second sub-pin 222 facing the second connection portion 112 is a plane, which is conducive to increasing the contact area between the second connection portion 112 and the second sub-pin 222, thereby facilitating the improvement of the electrical conduction efficiency.

[0059] In some embodiments, the side of the first connection portion 111 facing the first sub-pin 221 can be of other surface shapes to meet the needs, such as a convex surface, or other curved surfaces, or other bent surfaces, etc. The side of the first sub-pin 221 facing the first connection portion 111 can also be of other surface shapes to meet the needs and match the side of the first connection portion 111 facing the first sub-pin 221, such as a convex surface, or other curved surfaces, or other bent surfaces, etc. No excessive restrictions are made here.

[0060] In some embodiments, refer to FIG. 3, which is a top view of the female connector 200 in the embodiment shown in FIG. 1. The first pin 110 also includes a first auxiliary pin portion 113, which is electrically connected between the first connection portion 111 and the second connection portion 112. The second pin 220 also includes a second auxiliary pin portion 226, which is electrically connected between the first lead portion 223 and the first sub-pin 221, and the second auxiliary pin portion 226 is located at the bottom of the plug slot 210. When the electrical connector 10 is in a plugged state, the first auxiliary pin portion 113 abuts against the second auxiliary pin portion 226. The arrangement of the first auxiliary pin portion 113 and the second auxiliary pin portion 226 is conducive to increasing the contact area between the first pin 110 and the first sub-pin 221, and is conducive to improving the electrical conduction efficiency between the first pin 110 corresponding to the male connector 100 and the first sub-pin 221 corresponding to the female connector 200.

[0061] In some embodiments, the side of the first auxiliary pin portion 113 facing the second auxiliary pin portion 226 is a plane, and the side of the second auxiliary pin portion 226 facing the first auxiliary pin portion 113 is a plane. It can be understood that when the first auxiliary pin portion 113 and the second auxiliary pin portion 226 are in contact connection, it is a contact connection mode of planes against planes, which is conducive to increasing the contact area between the two, and further helps to further improve the electrical conduction efficiency between the first pin 110 corresponding to the male connector 100 and the first sub-pin 221 corresponding to the female connector 200.

[0062] In some embodiments, the side of the first auxiliary pin portion 113 facing the second auxiliary pin portion 226 can be other surface shapes to meet the needs, for example, it can be a convex surface, or other curved surfaces, or other bent surfaces, etc. The side of the second auxiliary pin portion 226 facing the first auxiliary pin portion 113 can also be other surface shapes to meet the needs, and it can match the side of the first auxiliary pin portion 113 facing the second auxiliary pin portion 226, for example, it can be a convex surface, or other curved surfaces, or other bent surfaces, etc., and no excessive restrictions are made here.

[0063] In some embodiments, referring to FIG. 1 and FIG. 2 , the female connector 200 further includes a top surface 231 and a bottom wall, the top surface 231 and the bottom wall are arranged at intervals along the third direction F3, and are adjacent or arranged at intervals along the first direction F1, and the second side wall is connected between the top surface 231 and the bottom wall. The first pin 110 further includes a support portion 114, the support portion 114 is electrically connected to a side of the second connection portion 112 away from the first auxiliary pin portion 113, and when the electrical connector 10 is in a plugged state, the support portion 114 abuts against the top surface 231. In this way, when the male connector 100 and the female connector 200 are plugged and connected to each other, the support portion 114 of the first pin 110 abuts against the top surface 231 of the female connector 200, thereby improving the plugging stability of the male connector 100 and the female connector 200, improving the abutment stability between the first pin 110 and the corresponding second pin 220, and reducing the risk of connection failure between the first pin 110 and the second pin 220.

[0064] In some embodiments, referring to FIG. 1 and FIG. 2 , the second sub-pin 222 includes an abutting surface 2221 facing away from the bottom wall, and when the male connector 100 is inserted into the insertion slot 210, the support portion 114 abuts against the abutting surface 2221. In this way, the support portion 114 abuts against the second sub-pin 222, thereby increasing the contact area between the first pin 110 and the second sub-pin 222, thereby improving the electrical conduction efficiency between the first pin 110 and the second sub-pin 222, and facilitating improving the detection sensitivity.

[0065] In some embodiments, referring to FIG. 1 and FIG. 2 , the contact surface 2221 is a plane, and the side of the support portion 114 facing the top surface 231 is a plane. It can be understood that when the second sub-pin 222 and the first pin 110 are in contact connection, it is a contact connection mode of planes against planes, which is conducive to increasing the contact area between the two, and further helps to further improve the electrical conduction efficiency between the corresponding first sub-pin 221 and the second sub-pin, and helps to improve the detection sensitivity.

[0066] In some embodiments, the abutment surface 2221 can be other surface shapes to meet the needs, for example, it can be a convex surface, or other curved surfaces, or other bent surfaces, etc. The side of the support portion 114 facing the top surface 231 can also be other surface shapes to meet the needs and match the abutment surface 2221, for example, it can be a convex surface, or other curved surfaces, or other bent surfaces, etc., and no excessive restrictions are made here.

[0067] In some embodiments, refer to FIG. 4, which is a top view of the male connector 100 and the female connector 200 after being plugged in the embodiment shown in FIG. 1. The electrical connector 10 further includes a plurality of male circuits 310, a plurality of female circuits 320, and a plurality of detection circuits 330. The male circuits 310 are electrically connected to the first pins 110, and the plurality of male circuits 310 correspond to the plurality of first pins 110 one by one. That is, the first pin 110 is electrically connected to the male circuit 310, and is correspondingly connected to the device of the second electronic system connected to the male connector 100 through the male circuit 310.

[0068] The female end circuit 320 is electrically connected to the first sub pin 221, and the plurality of female end circuits 320 correspond one to one to the plurality of first sub pins 221. It can be understood that one end of the first lead portion 223 is electrically connected to the first sub pin 221, and the other end is electrically connected to the female end circuit 320, and the female end circuit 320 is correspondingly connected to the device of the first electronic system connected to the female connector 200.

[0069] The detection circuit 330 is electrically connected to the second sub-pin 222, and the plurality of detection circuits 330 correspond one to one to the plurality of second sub-pins 222. It can be understood that one end of the second lead portion 224 is electrically connected to the second sub-pin 222, and the other end is electrically connected to the detection circuit 330, and the detection circuit 330 is correspondingly connected to a corresponding electrical testing device or electrical signal detection device, etc., for detection.

[0070] In some embodiments, as shown in FIG. 1 , the female connector 200 includes a female body 230, which defines a receiving slot. The first sub-pin 221 of the first pin 110 is disposed on one of the two inner side walls of the receiving slot along the first direction F1, the second sub-pin 222 of the first pin 110 is disposed on the other of the two inner side walls of the receiving slot along the first direction F1, and the second auxiliary pin portion 226 is disposed on the bottom wall of the receiving slot. The top surface 231 is the top side surface of the female body 230 close to the second sub-pin 222.

[0071] Two vias are provided on one side of the female end body 230 near the second sub-pin 222, and the vias are connected to the receiving slot and the external environment. The first lead portion 223 passes through one of the two vias to pass out of the receiving slot and at the same time passes out of the plugging slot 210. The second lead portion 224 passes through the other of the two vias to pass out of the receiving slot and at the same time passes out of the plugging slot 210. In this way, the second pin 220 is supported by the female end body 230, which is conducive to improving the stability of the second pin 220, and further to improving the interference stability between the first pin 110 and the second pin 220.

[0072] In some embodiments, referring to FIG. 1 , the male connector 100 includes a male body 120, a first connection portion 111 is disposed on a side wall of the male body 120 along a first direction F1, a second connection portion 112 is disposed on another side wall of the male body 120 along the first direction F1, and a first auxiliary pin portion 113 is disposed on a bottom wall of the male body 120. In this way, the male body 120 supports the first pin 110, which is beneficial to improving the stability of the first pin 110, and further beneficial to improving the interference stability between the first pin 110 and the second pin 220.

[0073] In the electrical connector 10 of the present application, the male connector 100 is plugged into the plug slot 210 and connected with the female connector 200. The electrical connection between the male connector 100 and the female connector 200 is achieved by abutting the corresponding first pin 110 and the second pin 220. At the same time, when the male connector 100 and the female connector 200 are relatively plugged, the first pin 110 is electrically connected between the first sub-pin 221 and the second sub-pin 222, so that the first sub-pin 221 and the second sub-pin 222 are electrically conductive. In this way, it can be understood that one of the first sub-pin 221 and the second sub-pin 222 can be set according to demand to connect the electronic system to which the female connector 200 needs to be connected. The other one is used to detect whether the same electrical signal as one of them is received, or whether the electrical signal sent by the electronic system connected to the female connector 200 is received. If an electrical signal is received from the electronic system connected to the female connector 200, it means that the electrical signal is smoothly transmitted to the second sub-pin 222 through the first sub-pin 221 and the second pin 220 in sequence, which means that the first sub-pin 221 and the second pin 220 are stably connected. That is, when the male connector 100 is connected to the female connector 200, the present application can obtain feedback on the electrical connection between the two, determine the connection status of the two, and thereby determine whether the two are successfully connected. This can reduce the time waste caused by connection errors and the electrical damage that may be caused by abnormal power-on due to connection errors.
