Abstract
Description
Technical Field
[0001] This utility model relates to the field of socket connector technology, and particularly to socket connectors and electrical connector assemblies. Background Technology
[0002] With the rapid development of electronic devices and display technology, DisplayPort (DP) and High-Definition Multimedia Interface (HDMI) have become the two most widely used video interface standards. They not only support high-definition video transmission, but can also carry audio and other auxiliary data. However, DP and HDMI interfaces have different physical dimensions. DP plugs are usually wider than HDMI plugs. If the socket is compatible with a DP plug, there may be misalignment issues when inserting an HDMI plug, resulting in extra space and causing the HDMI plug to wobble during use, affecting the stability of the connection. Utility Model Content
[0003] The main purpose of this utility model is to propose a socket connector and an electrical connector assembly, which aims to solve the technical problem that two different types of plugs cannot be adapted to a single socket.
[0004] To achieve the above objectives, the present invention provides a socket connector for inserting a first plug or a second plug, wherein the volume of the first plug is smaller than the volume of the second plug, and the socket connector comprises:
[0005] The mounting housing includes an outer shell and an inner shell disposed inside the outer shell, the inner shell forming a plug-in cavity with one end open;
[0006] A conductive structure is disposed within the insertion cavity, and the conductive structure extends toward the opening;
[0007] A foolproof spring clip, disposed in the inner shell, is used to prevent the first plug from entering the insertion cavity when the first plug is inserted in the wrong direction; and
[0008] A limiting spring is provided in the inner shell. The limiting spring is used to abut against the side of the first plug when the first plug is inserted to limit the first plug from shaking in the insertion cavity.
[0009] The anti-fooling spring and the limiting spring are used to abut against the surface of the first plug / second plug when the first plug or the second plug is inserted into the insertion cavity.
[0010] In one embodiment, the conductive structure includes:
[0011] An insulating body is disposed in the insertion cavity, the insulating body including an insulating base and an insulating plate disposed on the insulating base, the insulating plate extending toward the opening;
[0012] Multiple conductive terminals are provided, spaced apart on the insulating body. One end of each conductive terminal protrudes from the insulating plate to contact the first plug / second plug, and the other end extends out of the insertion cavity for connecting to a circuit board.
[0013] In one embodiment, a mounting hole is provided on one side of the inner shell near the opening, and a foolproof spring is provided at the mounting hole. The foolproof spring has a guide portion near the opening and a main body portion away from the opening. The guide portion is bent inward from the inner shell, and the width of the end of the main body portion near the guide portion is greater than that of the guide portion, so as to form a blocking position at the connection between the main body portion and the guide portion. The blocking position is used to abut against the end of the first plug when the first plug is inserted in reverse to prevent the first plug from entering the insertion cavity.
[0014] In one embodiment, the limiting spring is disposed in the mounting hole and near the side of the inner shell. The limiting spring includes a first end near the opening, a second end away from the opening, and a third end disposed between the first end and the second end. The first end is bent from the inner shell toward the inside of the insertion cavity to connect with the third end, and the second end is bent from the inner shell toward the inside of the insertion cavity to connect with the third end, such that the limiting spring is recessed inward and the third end is lower than the first plug, so that when the first plug is inserted into the insertion cavity, the third end abuts against the side of the first plug to limit the displacement of the first plug.
[0015] In one embodiment, the outer casing is provided with a limiting hole, which corresponds to the mounting hole, and a limiting rod is provided at the limiting hole, the limiting rod being perpendicular to the direction of the anti-fooling spring.
[0016] In one embodiment, the socket connector further includes a detection terminal disposed on the insulating body. The detection terminal has a first contact end protruding from the insulating plate and a second contact end extending out of the insertion cavity. The first contact end contacts the first plug / second plug within the insertion cavity, and the second contact end is used for conductive connection with the circuit board.
[0017] In one embodiment, the socket connector further includes a grounding terminal disposed on the insulating body, with one end of the grounding terminal inside the plug cavity and protruding from the insulating plate to contact the first plug / second plug, and the other end of the grounding terminal extending outside the plug cavity to be electrically connected to the circuit board.
[0018] In one embodiment, the outer shell and the inner shell are spot-welded together.
[0019] In one embodiment, the outer shell and the inner shell are made of stainless steel.
[0020] This utility model also proposes an electrical connector assembly, including a plug and a socket as described above, wherein the plug includes a first plug or a second plug, the volume of the first plug being smaller than the volume of the second plug, and the socket being used to insert the first plug or the second plug.
[0021] In this utility model's technical solution, the socket connector includes a mounting housing. The mounting housing adopts a double-shell configuration, comprising an outer shell and an inner shell arranged sequentially from the outside to the inside. A insertion cavity is formed within the inner shell for inserting a first plug or a second plug. When the first plug or the second plug is inserted into the insertion cavity from its open end, the conductive structure within the insertion cavity is electrically connected to the first plug or the second plug. The other end of the conductive structure is connected to a circuit board to achieve circuit continuity. Specifically, the cross-sectional shape of the insertion cavity of the inner shell is the same as the shape of the insertion end of the second plug, facilitating the insertion of the second plug. However, the insertion end of the first plug is smaller than the insertion end of the second plug, and the insertion end of the first plug is wider on one side and narrower on the other, making it prone to reverse insertion and resulting in a lack of conductivity. A foolproof spring is disposed on one side of the inner shell, facing the receiving cavity, and corresponds to the wider side of the first plug when correctly inserted. Therefore, if the first plug is inserted incorrectly, the foolproof spring corresponds to the narrower side of the first plug, causing the foolproof spring to abut against the narrower side of the first plug. At the corner where one end meets the side, it cannot enter the socket cavity. When the first plug is inserted in the correct direction, the wider side of the insertion end of the first plug corresponds to the anti-fooling spring, causing the anti-fooling spring to be pushed up and abut against the insertion end of the first plug. The anti-fooling spring can prevent the first plug from being inserted incorrectly and causing damage. At this time, the limiting spring abuts against the side of the first plug, which can prevent the first plug from wobbling left and right in the socket cavity, avoiding unstable conduction and reducing image or sound quality problems caused by poor contact. Whether the first plug or the second plug is inserted into the socket cavity, the limiting spring and the anti-fooling spring will abut against the surface of its insertion end, providing pressure to make its connection with the internal conductive structure more stable. The socket connector in this embodiment can be adapted to two different plug models without changing the equipment or using other converters. The setting that the first plug and the second plug are inserted into the socket cavity through one opening also reduces the space occupied by the equipment and facilitates use under different conditions.

[0047] This utility model proposes a socket connector and an electrical connector assembly.
[0048] Please see Figure 1 and Figure 4In one embodiment of this utility model, the socket connector 10 is used to insert a first plug 20 or a second plug 30, wherein the volume of the first plug 20 is smaller than the volume of the second plug 30, and the socket connector 10 includes:
[0049] Mounting housing 100 includes an outer shell 110 and an inner shell 120 disposed inside the outer shell 110. The inner shell 120 forms a plug-in cavity 101 with an opening at one end.
[0050] A conductive structure 200 is disposed in the insertion cavity 101, and the conductive structure 200 extends toward the opening;
[0051] A foolproof spring clip 300 is disposed in the inner shell 120. The foolproof spring clip 300 is used to prevent the first plug 20 from entering the insertion cavity 101 when the first plug 20 is inserted in the wrong direction; and
[0052] A limiting spring 400 is provided in the inner shell 120. The limiting spring 400 is used to abut against the side of the first plug 20 when the first plug 20 is inserted to limit the first plug 20 from shaking in the insertion cavity 101.
[0053] Among them, the anti-fooling spring 300 and the limiting spring 400 are used to abut against the surface of the first plug 20 / second plug 30 when the first plug 20 or the second plug 30 is inserted into the plug cavity 101.
[0054] In the technical solution of this utility model, the socket connector 10 includes a mounting housing 100, which is a double-shell configuration. The mounting housing 100 includes an outer shell 110 and an inner shell 120 arranged sequentially from the outside to the inside. A insertion cavity 101 is formed within the inner shell 120 for inserting a first plug 20 or a second plug 30. When the first plug 20 or the second plug 30 is inserted into the insertion cavity 101 from its open end, the conductive structure 200 within the insertion cavity 101 is electrically connected to the first plug 20 or the second plug 30, and the other end of the conductive structure 200 is connected to... A circuit board is connected to achieve circuit conduction. Specifically, the cross-sectional shape of the insertion cavity 101 of the inner shell 120 is the same as the insertion end shape of the second plug 30, facilitating the insertion of the second plug 30. However, the insertion end of the first plug 20 is smaller in volume than the insertion end of the second plug 30, and the insertion end of the first plug 20 is wider on one side and narrower on the other, making it prone to incorrect insertion and resulting in failure to conduct. The anti-misalignment spring 300 is located on one side of the inner shell 120, facing the receiving cavity, and the anti-misalignment spring 300 corresponds to the wider side of the first plug 20 when correctly inserted. Therefore, if... Figure 8 and Figure 9As shown, if the first plug 20 is inserted incorrectly, the anti-misalignment spring 300 corresponds to the narrower side of the first plug 20, causing the anti-misalignment spring 300 to abut against the corner 201 where the narrower end of the first plug 20 meets the side, preventing it from entering the insertion cavity 101. However, when the first plug 20 is inserted in the correct direction, as shown... Figure 10 As shown, the wider side of the insertion end of the first plug 20 corresponds to the anti-misalignment spring 300, causing the anti-misalignment spring 300 to be pushed up and abut against the insertion end of the first plug 20. The anti-misalignment spring 300 prevents the first plug 20 from being incorrectly inserted, thus avoiding damage. At this time, the limiting spring 400 abuts against the side of the first plug 20. Figure 11 and Figure 12 As shown, this design prevents the first plug 20 from wobbling left and right within the socket 101, avoiding unstable conductivity and reducing image or sound quality issues caused by poor contact. Whether the first plug 20 or the second plug 30 is inserted into the socket 101, the limiting spring 400 and the anti-fooling spring 300 abut against the surface of its insertion end, providing pressure and making its connection with the internal conductive structure 200 more stable. The socket connector 10 in this embodiment can accommodate two different plug models without requiring device replacement or other converters. Furthermore, the design of inserting the first plug 20 and the second plug 30 into the socket 101 through a single opening reduces the space occupied by the device, facilitating use under different conditions.
[0055] The first plug 20 is configured as an HDMI plug, and the second plug 30 is configured as a DisplayPort plug (hereinafter referred to as a DP plug). The insertion end of the HDMI plug is smaller than that of the DP plug, and the insertion end of the HDMI plug is asymmetrically arranged. Specifically, the HDMI plug has a first side 202 and a second side 203 arranged opposite each other, and a third side 204 and a fourth side 205 arranged opposite each other. The width of the first side 202 is smaller than that of the second side 203, and the third side 204 and the fourth side 205 are located at both ends of the second side 203. The third side 204 and the fourth side 205 are provided with corners 201 to connect the first side 202 and the second side 203. The first side 202, the second side 203, the third side 204, and the fourth side 205 form a socket. A connection terminal is provided in the socket, so that when the first plug 20 is inserted into the plug cavity 101, the conductive structure 200 is inserted into the socket and contacts the connection terminal to conduct electricity. When the first plug 20 is inserted into the plug cavity 101, as... Figure 8 and Figure 9 As shown, if the first plug 20 is inserted backwards, the first side 202 corresponds to one side of the anti-fooling spring 300, and the anti-fooling spring 300 abuts against the corner 201, preventing the first plug 20 from being inserted. When the first plug 20 is in the correct orientation, as shown... Figure 10-12 As shown, the second side 203 corresponds to one side of the anti-fooling spring 300. The second side 203 is wider, directly lifting the entire anti-fooling spring 300, making it easy to insert into the plug cavity 101. At this time, the limiting spring 400 abuts against the third side 204 / fourth side 205 to prevent the first plug 20 from shaking in the plug cavity 101, affecting the stability of the conductive connection. Correspondingly, the insertion end of the second plug 30 also has a socket. Since the shape of the second plug 30 is the same as the shape of the opening, the second plug 30 will not be inserted backward or shake when inserted into the plug cavity 101, ensuring stable conductivity. In addition, the mounting housing 100 includes an outer shell 110 and an inner shell 120. The double-shell design avoids the need for an excessively thick single shell while ensuring the strength of the housing. An excessively thick single shell would make it difficult for the anti-fooling spring 300 and the limiting spring 400 to deform, making it inconvenient to insert the first plug 20 and the second plug 30.
[0056] Please refer to Figure 4 In an embodiment of this utility model, the conductive structure 200 includes:
[0057] An insulating body 210 is disposed in the insertion cavity 101. The insulating body 210 includes an insulating base 211 and an insulating plate 212 disposed in the insulating base 211. The insulating plate 212 extends toward the opening.
[0058] Multiple conductive terminals 220 are provided, and the multiple conductive terminals 220 are spaced apart on the insulating body 210. One end of the conductive terminal 220 protrudes from the insulating plate 212 to contact the first plug 20 / second plug 30, and the other end extends out of the plug cavity 101 for connecting the circuit board.
[0059] Specifically, the conductive structure 200 includes an insulating body 210 and a conductive terminal 220. The insulating body 210 includes an insulating base 211 and an insulating plate 212. The insulating base 211 is installed in the insertion cavity 101 on the inner wall of the mounting housing 100 and away from the opening. The insulating plate 212 is installed on the other side of the insulating base 211 and extends towards the opening. The conductive terminal 220 is installed on the insulating base 211, with one end extending towards and protruding from the insulating plate 212, and the other end bent and extending in the opposite direction to protrude outside the insertion cavity 101 for easy connection. When the first plug 20 / second plug 30 is inserted into the plug cavity 101, the insulating plate 212 is inserted into the socket of the first plug 20 / second plug 30 so that the conductive terminal 220 can make contact with the connecting terminal and conduct electricity. There are multiple conductive terminals 220, which are spaced apart on the upper and lower sides of the insulating plate 212 along the width direction of the insulating plate 212. The conductive terminal 220 has a fixed end fixed on the insulating base 211, a conductive end protruding from the insulating plate 212, and a connecting end that extends out of the plug cavity 101 and connects to the circuit board. The conductive end and the connecting end are located at the two ends of the fixed end.
[0060] Please refer to Figure 2 , Figure 3 , Figures 4-12 In an embodiment of this utility model, a mounting hole 121 is provided on one side of the inner shell 120 near the opening. A foolproof spring 300 is provided at the mounting hole 121. The foolproof spring 300 has a guide portion 310 near the opening and a main body portion 320 away from the opening. The guide portion 310 is bent inward from the inner shell 120. The width of the end of the main body portion 320 near the guide portion 310 is greater than that of the guide portion 310, so as to form a blocking position 330 at the connection between the main body portion 320 and the guide portion 310. The blocking position 330 is used to abut against the end of the first plug 20 when the first plug 20 is inserted in reverse to prevent the first plug 20 from entering the insertion cavity 101.
[0061] Specifically, a mounting hole 121 is provided through one side of the inner shell 120, and a foolproof spring clip 300 is provided at the mounting hole 121. The foolproof spring clip 300 extends from the open end toward the direction away from the opening. The foolproof spring clip 300 includes a guide portion 310 and a main body portion 320. The main body portion 320 is connected to the inner shell 120 at the mounting hole 121 from the end away from the opening and extends toward the opening. The guide portion 310 extends from the open end toward the direction away from the opening and is connected to the main body portion 320. The width of the main body portion 320 is greater than that of the guide portion 310. The guide portion 310 bends from the open end toward the insertion cavity 101, and the connection point between the guide portion 310 and the main body portion 320 is lower than the inner wall of the inner shell 120. Since the main body portion 320 is wider than the guide portion 310, at the connection point, the excess part of the main body portion 320 is configured as a blocking position 330. The blocking position 330 is located near the middle of the insertion cavity 101, i.e. Figure 6 and Figure 10 As shown, when the first plug 20 is inserted in the correct direction or the second plug 30 is inserted into the socket 101, the insertion end is inserted into the socket 101 along the guide part 310, and the connection between the guide part 310 and the main body part 320 is pushed away from the socket 101 to insert into the socket 101. The connection between the guide part 310 and the main body part 320 abuts against the surface of the insertion end, which makes it more stable when inserted into the socket 101 and inconvenient to pull out. When the first plug 20 is inserted in the opposite direction, the blocking position 330 corresponds exactly to the corner 201 of the first plug 20. At this time, the blocking position 330 is lower than the corner 201, and the first plug 20 cannot be inserted into the socket 101. Therefore, it can only be reversed to avoid damage to the first plug 20 or the socket connector 10 after being inserted into the socket 101 in the wrong direction.
[0062] Please refer to Figures 4-12In an embodiment of this utility model, a limiting spring 400 is disposed in the mounting hole 121 and near the side of the inner shell 120. The limiting spring 400 includes a first end 410 near the opening, a second end 420 away from the opening, and a third end 430 disposed between the first end 410 and the second end 420. The first end 410 is bent from the inner shell 120 toward the inside of the insertion cavity 101 to connect with the third end 430, and the second end 420 is bent from the inner shell 120 toward the inside of the insertion cavity 101 to connect with the third end 430, so that the limiting spring 400 is recessed inward and the third end 430 is lower than the first plug 20, so that when the first plug 20 is inserted into the insertion cavity 101, the third end 430 abuts against the side of the first plug 20 to limit the displacement of the first plug 20.
[0063] Specifically, the mounting hole 121 is located near the side of the inner shell 120, while the anti-fooling spring 300 is located near the center, and the limiting spring 400 is located near the side. The limiting spring 400 and the anti-fooling spring 300 extend in the same direction, both extending from the open end away from the open end. The limiting spring 400 includes a third end 430 and first ends 410 and second ends 420 at both ends of the third end 430. Both the first ends 410 and the second ends 420 are bent towards the insertion cavity 101, so that the height of the third end 430 is lower than that of the first ends 410 and the second ends 420. That is, when viewed from the side, the limiting spring 400 has a structure that is concave in the middle and high at both ends. Figure 11 and Figure 12 As shown, when the first plug 20 is inserted into the socket 101 in the correct direction, the third end 430 abuts against the third side 204 / fourth side 205 to limit the first plug 20 from swaying left and right in the socket 101 and ensure the stability of the conductive connection between the first plug 20 and the socket.
[0064] Please refer to Figure 4 In an embodiment of this utility model, the outer shell 110 is provided with a limiting hole 111, which corresponds to the mounting hole 121. A limiting rod 112 is provided at the limiting hole 111, and the limiting rod 112 is perpendicular to the direction of the anti-fooling spring 300.
[0065] Specifically, a limiting hole 111 is provided at the position of the mounting hole 121 on the outer shell 110, so that after the first plug 20 / second plug 30 is inserted, the first plug 20 / second plug 30 will push up the limiting spring 400 and the anti-fooling spring 300, causing them to deform in the direction of the outer shell 110. The setting of the limiting hole 111 facilitates the upward pushing of the limiting spring 400 and the anti-fooling spring 300. A limiting rod 112 is provided at the limiting hole 111, which spans the limiting hole 111 and can block the limiting spring 400 and the anti-fooling spring 300, so that the limiting spring 400 and the anti-fooling spring 300 tend to press down into the insertion cavity 101, which facilitates pressing the first plug 20 / second plug 30 and preventing them from being easily pulled out.
[0066] In another embodiment, such as Figure 5 and Figure 8 As shown, two mounting holes 121 are provided on both sides of one side of the inner shell 120. Each mounting hole 121 is provided with a foolproof spring 300. Correspondingly, two limiting holes 111 are also provided on the outer shell 110 to correspond to the two mounting holes 121. The two foolproof springs 300 can simultaneously abut against the two corners 201 of the first plug 20, which can better prevent the first plug 20 from entering the insertion cavity 101 in reverse.
[0067] Please refer to Figure 4 In an embodiment of this utility model, the socket connector 10 further includes a detection terminal 500. The detection terminal 500 is disposed on the insulating body 210. The detection terminal 500 has a first contact end protruding from the insulating plate 212 and a second contact end extending out of the insertion cavity 101. The first contact end contacts the first plug 20 / second plug 30 in the insertion cavity 101, and the second contact end is used for conductive connection with the circuit board.
[0068] Specifically, the detection terminal 500 is fixed on the insulating body 210. The first contact end extends toward the insulating plate 212 and protrudes from the insulating plate 212. The second contact end extends out of the plug cavity 101 and connects to the circuit board. When the first plug 20 / second plug 30 is inserted into the plug cavity 101, the first contact end contacts it and determines whether the plug inserted into the plug cavity 101 is the first plug 20 or the second plug 30, so as to better transmit the signal. Specifically, a logic circuit can be set on the circuit board. When the detection terminal 500 receives the signal, it determines the plug type according to the preset rules and configures the signal path accordingly.
[0069] The detection terminal 500 can be connected to the insulating body 210 by welding or crimping, without limitation, and can be made of highly conductive and wear-resistant materials such as gold-plated copper or beryllium copper to ensure a reliable electrical connection.
[0070] Please refer to Figure 4In an embodiment of this utility model, the socket connector 10 further includes a grounding terminal 600. The grounding terminal 600 is disposed on the insulating body 210, and one end of the grounding terminal 600 is disposed in the insertion cavity 101 and protrudes from the insulating plate 212 to contact the first plug 20 / second plug 30. The other end of the grounding terminal 600 extends out of the insertion cavity 101 to be electrically connected to the circuit board.
[0071] Specifically, a grounding terminal 600 is also provided corresponding to the detection terminal 500. The detection terminal 500 and the grounding terminal 600 are respectively located at both ends of the insulating body 210. One end is located on the insulating plate 212 and extends along the direction of the insulating plate 212, protruding from the insulating plate 212 and used to connect the grounding pin on the first plug 20 / second plug 30. The other end extends out of the plug cavity 101 to connect to the grounding network on the circuit board. Specifically, soldering can be used to ensure that the connection has a low-impedance grounding path. The grounding terminal 600 can provide a safe electrical connection, reduce the influence of electrostatic discharge and electromagnetic interference, and help reduce signal noise, improve the quality of video and audio transmission, and reduce the failure rate caused by poor grounding.
[0072] The grounding terminal 600 is the same as the detection terminal 500. It can be welded or crimped to the insulating body 210 without limitation. It can also be made of highly conductive and wear-resistant materials such as gold-plated copper or beryllium copper to ensure a reliable electrical connection.
[0073] Referring to the figure, in the embodiment of this utility model, the outer shell 110 and the inner shell 120 are spot welded together, so that a firm connection is formed between the outer shell 110 and the inner shell 120, improving mechanical strength, ensuring that the outer shell 110 and the inner shell 120 fit tightly together, preventing loosening or separation under vibration, and the spot welded connection has good conductivity, effectively reducing the heat accumulation generated when current passes through, and reducing the risk of overheating.
[0074] In the embodiments of this utility model, the outer shell 110 and the inner shell 120 are made of stainless steel, which not only has good mechanical strength but also has certain corrosion resistance. The inner shell 120 is integrally formed with the anti-misalignment spring 300 and the limiting spring 400, which also improves the strength of the structure. The inner shell 120, the anti-misalignment spring 300, and the limiting spring 400 can be made of stainless steel with a certain degree of elasticity, such as stainless steel with a high nickel content, which combines elasticity and strength. This allows the limiting spring 400 and the mechanical spring to be pushed upward when the first plug 20 / second plug 30 is inserted, and the limiting spring 400 and the anti-misalignment spring 300 to rebound when the plug is pulled out, ensuring stable insertion and extraction force. It also provides a good anti-reverse insertion function when the first plug 20 is subsequently inserted in reverse.
[0075] This utility model discloses an electrical connector assembly, characterized in that it includes a plug and a socket. The plug includes a first plug 20 or a second plug 30, the volume of the first plug 20 being smaller than the volume of the second plug 30. The socket is used to insert the first plug 20 or the second plug 30. The specific structure of the socket is as described in the above embodiments. Since this electrical connector assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. Specifically, the first plug 20 is configured as an HDMI plug, and the second plug 30 is configured as a DisplayPort plug (hereinafter referred to as a DP plug). The insertion end of the HDMI plug is smaller than the insertion end of the DP plug, and the insertion end of the HDMI plug is asymmetrically arranged. Through this socket, both HDMI and DP plugs can be inserted separately, and damage to the plug and socket can be prevented by inserting the HDMI plug in reverse. Please also refer to... Figure 6 and Figure 7 A hook portion 301 is provided on one side of the second plug 30 corresponding to the limiting hole 111. When the second plug 30 is inserted, the hook portion 301 cooperates with the limiting rod 112 to prevent the second plug 30 from being easily pulled out and improve the stability of the connection.
