Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a plug connector and connector assembly with low characteristic impedance in the contact area.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A plug connector, comprising:

[0006] An insulating base is formed with a plug-in groove and a through groove, wherein the through groove is connected to the plug-in groove;

[0007] The plug has a conductive terminal located within the insertion slot and connected to the insulating base. The conductive terminal has an abutment portion located within the insertion slot.

[0008] In one embodiment, the insulating base further forms a receiving cavity, which communicates with the insertion slot, and the through slot communicates with both the receiving cavity and the insertion slot.

[0009] In one embodiment, the abutting portion is located in the area where the insertion slot and the through slot are connected.

[0010] In one embodiment, the abutting portion protrudes into the receiving cavity; and / or,

[0011] The portion of the spring arm of the plug's conductive terminal that connects to the contact portion is correspondingly positioned to the through groove.

[0012] In one embodiment, the number of the plug conductive terminals is at least two, namely a first plug conductive terminal and a second plug conductive terminal;

[0013] The number of the insertion slots is at least two, namely a first insertion slot and a second insertion slot, both of which are connected to the receiving cavity; the through slot includes a first through slot and a second through slot; the first through slot is connected to the first insertion slot and the receiving cavity respectively, and the second through slot is connected to the second insertion slot and the receiving cavity respectively.

[0014] The first plug conductive terminal is located in the first insertion slot and connected to the insulating base, and the contact portion of the first plug conductive terminal is located in the area where the first insertion slot and the first through slot are connected; the second plug conductive terminal is located in the second insertion slot and connected to the insulating base, and the contact portion of the second plug conductive terminal is located in the area where the second insertion slot and the second through slot are connected.

[0015] In one embodiment, the contact portion of the first plug conductive terminal and the contact portion of the second plug conductive terminal both protrude into the receiving cavity.

[0016] In one embodiment, both the contact portion of the first plug conductive terminal and the contact portion of the second plug conductive terminal are bent, and both the contact portions of the first plug conductive terminal and the second plug conductive terminal are bent toward each other.

[0017] In one embodiment, each of the plug conductive terminals includes a solder pin, a locking point, a spring arm, and a contact portion connected in sequence. The solder pin is at least partially located outside the insulating base. The locking point is located inside the insertion slot and is fixedly connected to the insulating base. A portion of the spring arm is located in the area where the insertion slot communicates with the through slot.

[0018] In one embodiment, the spring arm includes a first bending portion, a second bending portion, a third bending portion, and a fourth bending portion connected in sequence. The end of the first bending portion away from the second bending portion is connected to the locking point fixing portion. The bending direction of the first bending portion is opposite to the bending direction of the second bending portion. The bending direction of the third bending portion is opposite to the bending direction of the fourth bending portion. The end of the fourth bending portion away from the third bending portion is connected to the abutting portion.

[0019] In one embodiment, the abutting portion is provided with an abutting point, and the fourth bending portion bends toward the side near the abutting point; and / or,

[0020] The contact portion includes a fifth bend and a sixth bend connected to each other.

Furthermore, the contact portion is located within the mating groove, and the groove connects to the through groove, allowing the inner cavity of the insulating base to communicate with its outer perimeter through the through groove. This prevents the plug's conductive terminals from being hindered by elastic deformation during mating with the socket connector. Simultaneously, the through groove effectively reduces the capacitance of the contact area between the plug's and socket's conductive terminals, significantly improving the characteristic impedance of the contact area and ensuring it meets design requirements.

[0042] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0043] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0044] 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 invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] This application provides a plug connector including an insulating base and a plug conductive terminal. The insulating base has a mating groove and a through groove, the through groove communicating with the mating groove. The plug conductive terminal is located in the mating groove and connected to the insulating base. The plug conductive terminal has an abutting portion located in the mating groove. Because the insulating base has a mating groove and a through groove, and the mating groove and through groove communicate, and because the plug conductive terminal is located in the mating groove and connected to the insulating base, the plug conductive terminal is fixedly mounted on the insulating base. Furthermore, because the abutting portion is located in the mating groove, and the mating groove and through groove communicate, the inner cavity of the insulating base communicates with the outer space of the insulating base through the slot of the through groove. This avoids the problem of elastic deformation of the plug conductive terminal being hindered when the plug connector and socket connector are mated. Simultaneously, the through groove effectively reduces the capacitance of the contact area between the plug conductive terminal and the socket conductive terminal, greatly improving the characteristic impedance of the contact area and ensuring that the characteristic impedance of the contact area meets design requirements.

[0046] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0047] like Figures 1 to 2bAs shown, one embodiment of the connector assembly 10 includes a plug connector 100. In one embodiment, the connector assembly 10 further includes a receptacle connector 200, the plug connector 100 and the receptacle connector 200 being inserted to achieve electrical connection between the plug connector 100 and the receptacle connector 200. In this embodiment, the connector assembly 10 is used to electrically connect to two circuit boards 20 respectively, wherein the plug connector 100 is electrically connected to one circuit board and the receptacle connector 200 is electrically connected to the other circuit board.

[0048] See also Figures 3 to 5 In one embodiment, the plug connector 100 includes an insulating base 100a and a plug conductive terminal 100b. The insulating base 100a has a mating groove 108 and a through groove 104. The through groove 104 communicates with the mating groove 108, allowing the inner cavity of the insulating base to communicate with the outer space of the insulating base through the slot of the through groove. This removes the insulating material from the middle of the insulating base, effectively reducing the capacitance of the contact area between the plug conductive terminal and the socket conductive terminal, greatly improving the characteristic impedance of the contact area, and ensuring that the characteristic impedance of the contact area meets the design requirements. The plug conductive terminal 100b is located in the mating groove 108 and connected to the insulating base 100a, so that the plug conductive terminal 100b is fixedly assembled on the insulating base 100a. The plug conductive terminal 100b has an abutment portion 110, which is located in the insertion groove 108. The abutment portion 110 is used to abut against the socket conductive terminal 200a of the socket connector 200 when the plug connector 100 and the socket connector 200 are plugged in, so that the plug connector 100 and the socket connector 200 are electrically connected to realize signal transmission. At the same time, the part of the abutment portion 110 that abuts against the socket conductive terminal of the socket connector 200 is exposed to the air, and can effectively reduce the capacitance of the contact area between the plug conductive terminal and the socket conductive terminal, greatly improve the characteristic impedance of the contact area, and ensure that the characteristic impedance of the contact area meets the design requirements.

[0049] The aforementioned plug connector 100 has an insulating base 100a with a mating groove 108 and a through groove 104. The mating groove 108 and the through groove 104 are connected. The plug conductive terminal 100b is located in the mating groove 108 and connected to the insulating base 100a, thus fixing the plug conductive terminal 100b to the insulating base 100a. Furthermore, since the contact part 110 is located in the mating groove 108 and the mating groove 108 is connected to the through groove 104, the inner cavity of the insulating base is connected to the outer space of the insulating base through the slot of the through groove. This avoids the problem of the plug conductive terminal being hindered by elastic deformation when the plug connector and the socket connector are mated. At the same time, the through groove can effectively reduce the capacitance of the contact area between the plug conductive terminal and the socket conductive terminal, greatly improve the characteristic impedance of the contact area, and ensure that the characteristic impedance of the contact area meets the design requirements.

[0050] See also Figure 4 and Figure 5 In one embodiment, the insulating base 100a further includes a receiving cavity 106, which communicates with the insertion slot 108. A through slot 104 communicates with both the receiving cavity 106 and the insertion slot 108, allowing the receiving cavity of the insulating base to communicate with the peripheral space of the insulating base through the slot of the through slot. This removes the insulating material from the middle of the insulating base, effectively reducing the capacitance of the contact area between the plug's conductive terminals and the socket's conductive terminals, significantly improving the characteristic impedance of the contact area, and ensuring that the characteristic impedance of the contact area meets design requirements. In this embodiment, the receiving cavity 106 is formed in the middle portion of the insulating base 100a. It is understood that in other embodiments, the receiving cavity 106 is not limited to being formed in the middle portion of the insulating base 100a; for example, the receiving cavity 106 may be formed in a region of the insulating base 100a that is offset from the middle portion.

[0051] See also Figure 4 and Figure 5 In one embodiment, the contact portion 110 is located in the area where the insertion groove 108 and the through groove 104 are connected. That is, the contact portion 110 is correspondingly disposed at the position where the insertion groove 108 and the through groove 104 are connected, i.e., the contact portion and the through groove are correspondingly disposed. This allows the receiving cavity of the insulating base to communicate with the outer space of the insulating base through the slot of the through groove. This eliminates the presence of insulating material in the middle of the insulating base, effectively reducing the capacitance of the contact area between the plug's conductive terminals and the socket's conductive terminals, greatly improving the characteristic impedance of the contact area, and ensuring that the characteristic impedance of the contact area meets design requirements. See also... Figure 5aFurthermore, the insulating base 100a has a through groove 104 formed in the area corresponding to the contact portion 110, so that the contact portion 110 can reliably elastically deform when it comes into contact with the socket conductive terminal 200a of the socket connector 200. That is, when the plug conductive terminal 100b comes into contact with the socket conductive terminal 200a of the socket connector 200, there is a reliable deformation space at the position corresponding to the through groove 104. This avoids the problem that the elastic deformation of the plug conductive terminal 100b is hindered by the insulating base 100a. Even if the plug conductive terminal 100b is compressed without obstruction, the through groove 302 connects the inner cavity of the plug connector 100 with the outer space, exposing the contact portion 110 of the plug conductive terminal 100b to the air. The terminal can be observed from the outside of the connector assembly 10, which plays a role in avoiding compression of the elastic wall and greatly improving the characteristic impedance of the electrical connection of the connector assembly 10 after the plug connector 100 and the socket connector 200 are mated. Furthermore, the portion of the spring arm 140 of the plug conductive terminal connected to the contact portion 110 is provided in accordance with the through groove, so that the spring arm can better avoid obstruction by the insulating base when it is elastically deformed.

[0052] like Figure 2a and Figure 6As shown, in one embodiment, the socket connector 200 includes a socket body 200b and a socket conductive terminal 200a. The socket body 200b has a communicating mounting groove 202 and a mating cavity 204. The socket conductive terminal 200a passes through the mounting groove 202 and is connected to the socket body 200b. The insulating base 100a is located in the mating cavity 204 and is plugged into the socket body 200b. In one embodiment, a tongue portion 204a protrudes from the inner wall of the insertion cavity 204. The tongue portion 204a forms a first fixing groove 206 communicating with the mounting groove 202. The socket conductive terminal 200a is partially located within the first fixing groove 206 and connected to the tongue portion 204a. The tongue portion 204a is located within the receiving cavity 106 and inserted into the insulating base 100a, allowing the plug connector 100 and the socket connector 200 to be connected. The abutment portion 110 abuts against the socket conductive terminal 200a within the receiving cavity 106, thereby reliably electrically connecting the plug conductive terminal 100b and the socket conductive terminal 200a. This ensures that the socket connector 200 and the plug connector 100 are electrically connected during insertion. Since the plug connector 100 and the socket connector 200 are inserted into each other, the plug connector 100 and the socket connector 200 are connected in a mating manner, which makes the mating interface of the plug connector 100 and the socket connector 200 have good stability during the floating process. Since the conductive terminal 200a of the socket is located in the first fixing groove 206 and connected to the tongue portion 204a, and the contact portion 110 abuts against the conductive terminal 200a of the socket in the mating cavity 204, coupled with the mating connection of the plug connector 100 and the socket connector 200, the plug connector 100 and the socket connector 200 are reliably electrically connected, which solves the problem of poor electrical connection stability of the connector assembly 10.

[0053] like Figure 2a and Figure 5As shown, in one embodiment, the number of plug conductive terminals 100b is at least two, namely a first plug conductive terminal 1002 and a second plug conductive terminal 1004. The first plug conductive terminal 1002 and the second plug conductive terminal 1004 are located on both sides of the tongue portion 204a. The number of insertion slots 108 is at least two, namely a first insertion slot 1082 and a second insertion slot 1084, both of which are connected to the receiving cavity 106; the through slot 104 includes a first through slot 1042 and a second through slot 1044; the first through slot 1042 is connected to the first insertion slot 1082 and the receiving cavity 106, and the second through slot 1044 is connected to the second insertion slot 1084 and the receiving cavity 106, respectively; the first plug conductive terminal 1002 is located in the first insertion slot 1082 and connected to the insulating base 100a, and the contact portion 1 of the first plug conductive terminal 1002 is... 10 is located in the area corresponding to the first plug groove 1082 and the first through groove 1042; the second plug conductive terminal 1004 is located in the second plug groove 1084 and connected to the insulating base 100a, and the contact portion 110 of the second plug conductive terminal 1004 is located in the area corresponding to the second plug groove 1084 and the second through groove 1044, so that each plug conductive terminal 100b is assembled and connected to the insulating base 100a, and at the same time, each plug conductive terminal 100b is exposed to the air through the corresponding plug groove 108 and through groove 104, so that each plug conductive terminal 100b has better deformation space and characteristic impedance. In this embodiment, there are multiple plug conductive terminals 100b, multiple insertion slots 108, and multiple through slots 104. The multiple insertion slots 108 and multiple through slots 104 are connected in a one-to-one correspondence. The multiple through slots 104 are all connected to the receiving cavity 106. The multiple plug conductive terminals 100b are located in the multiple insertion slots 108, and the contact portion 110 of each plug conductive terminal 100b is located in the area where the corresponding insertion slot 108 and the corresponding through slot 104 are connected. The multiple plug conductive terminals 100b are arranged in two rows, so that the multiple plug conductive terminals 100b can be reliably installed on the insulating base 100a. Each plug conductive terminal 100b is electrically connected to the corresponding socket conductive terminal through contact. At the same time, the impedance characteristics of each plug conductive terminal 100b and the corresponding socket conductive terminal through contact are greatly improved, ensuring that the characteristic impedance of the contact area meets the design requirements.Furthermore, the insulating base 100a has a corresponding through groove 104 formed in the area corresponding to the contact portion 110 of each plug conductive terminal 100b, so that the contact portion 110 of each plug conductive terminal 100b can reliably elastically deform when it comes into contact with the corresponding socket conductive terminal 200a. That is, when each plug conductive terminal 100b comes into contact with the corresponding socket conductive terminal 200a, there is a reliable deformation space at the position corresponding to the corresponding through groove 104. This avoids the problem that the elastic deformation of each plug conductive terminal 100b is hindered by the insulating base 100a, so that even when each plug conductive terminal 100b is compressed, there is no obstruction, and multiple signals can be reliably transmitted at the same time. For example. Figure 2a and Figure 6 As shown, in this embodiment, there are multiple mounting slots 202 and multiple socket conductive terminals 200a. Multiple socket conductive terminals 200a are respectively inserted into the corresponding mounting slots 202 and connected to the socket body 200b. Multiple socket conductive terminals 200a respectively abut against the contact portions 110 of multiple plug conductive terminals 100b one by one, so that each socket conductive terminal 200a abuts against the contact portion 110 of the corresponding plug conductive terminal 100b, thus electrically connecting each socket conductive terminal 200a to the contact portion 110 of the corresponding plug conductive terminal 100b, thereby simultaneously realizing the transmission of multiple electrical connection signals.

[0054] Such as 2a and Figure 5 As shown, in one embodiment, the abutment portion 110 protrudes into the receiving cavity 106, so that the abutment portion 110 reliably abuts against the terminal of the socket connector 200 when the plug connector 100 and the socket connector 200 are inserted. In one embodiment, the abutment portions 110 of the first plug conductive terminal 1002 and the second plug conductive terminal 1004 both protrude into the receiving cavity 106, so that the abutment portion 110 of each plug conductive terminal 100b can abut against and conduct electricity with the corresponding socket conductive terminal 200a when the plug connector 100 and the socket connector 200 are inserted.

[0055] Such as 2a and Figure 5As shown, in one embodiment, the contact portions 110 of the plug conductive terminals 100b are all bent toward the side closer to the tongue portion 204a, so that the contact portions 110 better abut against the socket conductive terminals 200a. In this embodiment, the number of plug conductive terminals 100b is at least two, and the contact portions 110 of both plug conductive terminals 100b are bent toward the side closer to the tongue portion 204a, so that the contact portions 110 of the two plug conductive terminals 100b better abut against the two socket conductive terminals 200a respectively. In this embodiment, the contact portions 110 of the two plug conductive terminals 100b are bent toward the side near the tongue portion 204a, and each plug conductive terminal 100b is formed by bending back the foremost part of the terminal in the contact area. This allows the plug connector 100 and the socket connector 200 to each form at least one contact point on the left and right sides of the contact area, so that the plug connector 100 and the socket connector 200 have better insertion and extraction force after being plugged in, and at the same time, the resistance encountered when the plug connector 100 and the socket connector 200 are plugged in is smaller. In one embodiment, the contact portion 110 of the first plug conductive terminal 1002 and the contact portion 110 of the second plug conductive terminal 1004 are both bent, and the contact portions 110 of the first plug conductive terminal 1002 and the contact portions 110 of the second plug conductive terminal 1004 are bent toward each other. When the plug connector 100 and the socket connector 200 are inserted, the contact portions 110 of the first plug conductive terminal 1002 and the contact portions 110 of the second plug conductive terminal 1004 can better clamp and abut against the tongue portion 204a of the socket connector 200, and at the same time, the plug connector 100 and the socket connector 200 are reliably electrically connected.

[0056] Such as 2a and Figure 5 As shown, in one embodiment, each plug conductive terminal 100b includes a soldering pin 120, a locking point 130, a spring arm 140, and an abutment portion 110 connected in sequence. The soldering pin 120 is at least partially located outside the insulating base 100a. The locking point 130 is located within the insertion groove 108 and is fixedly connected to the insulating base 100a. A portion of the spring arm 140 is located in the area where the insertion groove 108 communicates with the through groove 104. When each plug conductive terminal 100b abuts against the socket conductive terminal 200a, a shape is formed. When the spring arm 140 deforms, the deformation of the spring arm 140 is relatively large. Since part of the spring arm 140 is located in the area where the plug groove 108 and the through groove 104 are connected, the contact part 110 can reliably deform elastically when it comes into contact with the socket conductive terminal 200a. That is, when the plug conductive terminal 100b comes into contact with the socket conductive terminal 200a, there is a reliable deformation space at the position corresponding to the through groove 104. This avoids the problem that the elastic deformation of the plug conductive terminal 100b is hindered by the insulating base 100a. Even when the plug conductive terminal 100b is compressed, there is no obstruction.

[0057] For example, 2a Figure 5 and Figure 7 As shown, in one embodiment, the spring arm portion 140 of each plug conductive terminal 100b includes a first bending portion 142, a second bending portion 144, a third bending portion 146, and a fourth bending portion 148 connected in sequence. The end of the first bending portion 142 away from the second bending portion 144 is connected to the locking point fixing portion 130. The bending direction of the first bending portion 142 is opposite to the bending direction of the second bending portion 144. The bending direction of the third bending portion 146 is opposite to the bending direction of the fourth bending portion 148. The end of the fourth bending portion 148 away from the third bending portion 146 is connected to the abutment portion 110, so that the spring arm portion 140 has good elastic deformation and the structure of the spring arm portion 140 is more compact. In one embodiment, the bending angle of the first bending portion 142 is 60 degrees to 100 degrees, the bending angle of the second bending portion is 60 degrees to 100 degrees, the bending angle of the third bending portion is 100 degrees to 160 degrees, and the bending angle of the fourth bending portion is 100 degrees to 160 degrees. In this embodiment, the bending angle of the first bending portion 142 is 90 degrees, the bending angle of the second bending portion is 90 degrees, the bending angle of the third bending portion is 130 degrees, and the bending angle of the fourth bending portion is 130 degrees, so that the elastic arm portion 140 can better elastically abut against the contact portion 110 when inserted and abutted.

[0058] For example, 2a Figure 5 and Figure 7 As shown, in one embodiment, the abutment portion 110 is provided with an abutment point 112, and the fourth bend portion 148 bends toward the side near the abutment point, so that the spring arm portion 140 has better elasticity when the abutment portion 110 abuts against the socket conductive terminal 200a, thereby allowing the abutment portion 110 to better abut against the socket conductive terminal 200a, and making the abutment portion 110 and the socket conductive terminal 200a reliably electrically connected; and / or, in one embodiment, the abutment portion 110 includes a fifth bend portion 113 and a sixth bend portion 115 connected together, the end of the fifth bend portion 113 away from the sixth bend portion 115 is connected to the end of the fourth bend portion 148 away from the third bend portion 146, and both the fifth bend portion 113 and the sixth bend portion 115 are bent toward the side near the third bend portion 146. and / or, as Figure 4 As shown, in one embodiment, the plug connector 100 further includes a plug soldering reinforcing foot 100c. An insulating base 100a has a mating groove 108. The plug soldering reinforcing foot 100c passes through the mating groove 108 and connects to the insulating base 100a, thus fixing the insulating base 100a and the plug soldering reinforcing foot 100c together. In this embodiment, the plug connector 100 is fixedly soldered to the circuit board via the plug soldering reinforcing foot 100c.

[0059] For example, 2a Figure 5 and Figure 6 As shown, in one embodiment, the socket body 200b includes a fixed base 210 and a floating base 220. The fixed base 210 has a receiving groove 203, and the floating base 220 is located in the receiving groove 203 and is movably connected to the fixed base 210. See also... Figures 8 to 10 In this embodiment, the socket body 200b is a floating base 220, and the receiving groove 203 is used to receive part of the structure of the floating base 220, so that the fixed base 210 is used to receive the lower half 223 of the floating base 220, thereby enabling the insulating base 100a and the socket body 200b to achieve a floating connection, and enabling the connector assembly 10 to achieve board-to-board electrical connection. Furthermore, the mounting groove 202 includes a second fixing groove 202a formed in the fixed base 210 and a connecting groove 202b formed in the floating base 220. The second fixing groove 202a communicates with the connecting groove 202b. The insertion cavity 204 is formed in the floating base 220, so that the floating base 220 and the insulating base 100a are mutually inserted and connected. The socket conductive terminal 200a is located in the second fixing groove 202a and connected to the fixed base 210. The socket conductive terminal 200a is inserted into the first fixing groove 206 through the connecting groove 202b, so that the socket conductive terminal 200a is connected to the fixed base 210 and the floating base 220 respectively, and the fixed base 210 and the floating base 220 are relatively floatingly connected. In this embodiment, the number of mounting grooves 202 and socket conductive terminals 200a is at least two, and the two socket conductive terminals 200a are located on both sides of the tongue portion 204a. Each socket conductive terminal 200a is located in the corresponding second fixing groove 202a and connected to the fixing base 210. Each socket conductive terminal 200a is inserted into the corresponding first fixing groove 206 through the corresponding connecting groove 202b, so that each socket conductive terminal 200a is connected to the fixing base 210 and the floating base 220 respectively, and the fixing base 210 and the floating base 220 are relatively floatingly connected.

[0060] Such as 2a and Figure 6As shown, the connecting groove 202b further includes a connecting hole 2022 and a supporting clearance groove 2024 that are connected in communication. The socket conductive terminal 200a passes through the connecting hole 2022, and the socket conductive terminal 200a is located in the supporting clearance groove 2024 and connected to the floating base. This allows the socket conductive terminal to be reliably supported and installed on the floating base, thereby allowing the socket conductive terminal to be better elastically supported on the floating base. At the same time, it avoids the problem of large sliding between the socket conductive terminal and the floating base during the floating process relative to the fixed base, allowing the floating base to float better relative to the fixed base. In this embodiment, the connecting hole 2022 is connected to the first fixed groove 206. Furthermore, the supporting clearance groove 2024 is formed on the bottom surface of the floating base 220, making the processing difficulty of the supporting clearance groove 2024 lower. Furthermore, the inner wall of the support relief groove 2024 is formed with a support slope 2025, so that the support relief groove 2024 can better adapt to the deformation of the socket conductive terminal, thereby making the socket conductive terminal better fit and support the floating base.

[0061] For example, 2a Figure 6 and Figure 7As shown, in one embodiment, the socket conductive terminal 200a includes a socket soldering portion 250, a connecting interference portion 260, a middle bending portion 230, and an abutting interference portion 240 connected in sequence. The connecting interference portion 260 is located in the second fixing groove 202a and connected to the fixing base 210. The middle bending portion 230 of the socket conductive terminal 200a is located in the gap between the floating base 220 and the fixing base 210, so that the socket conductive terminal 200a is elastically supported on the floating base 220, thereby making the floating base 220 float and connected to the fixing base 210, thus enabling the connector assembly 10 to achieve a board-to-board floating connection. The abutting interference portion 240 of the socket conductive terminal 200a is inserted into the corresponding first fixing groove 206 through the connecting groove 202b, so that the socket conductive terminal 200a is assembled and connected to the tongue portion 204a. In this embodiment, the number of socket conductive terminals 200a is at least two. The connection interference portion 260 of each socket conductive terminal 200a is located in the corresponding second fixing groove 202a and connected to the fixing base 210, so that each socket conductive terminal 200a is connected to the fixing base 210. The middle bending portion 230 of each socket conductive terminal 200a is located in the gap between the floating base 220 and the fixing base 210, so that each socket conductive terminal 200a is elastically supported on the floating base 220, thus making the floating base 220 float and connected to the fixing base 210, thereby enabling the connector assembly 10 to achieve a board-to-board floating connection. The abutting interference portion 240 of each socket conductive terminal 200a is inserted into the corresponding first fixing groove 206 through the corresponding connecting groove 202b, so that each socket conductive terminal 200a is assembled and connected to the tongue portion 204a. In one embodiment, the socket welding portion 250, the connecting interference portion 260, the intermediate bending portion 230, and the abutting interference portion 240 are integrally formed, so that the socket welding portion 250, the connecting interference portion 260, the intermediate bending portion 230, and the abutting interference portion 240 are reliably fixedly connected in sequence, while making the structure of each socket conductive terminal 200a more compact. It can be understood that in other embodiments, the socket welding portion 250, the connecting interference portion 260, the intermediate bending portion 230, and the abutting interference portion 240 may also be formed separately and fixedly connected by welding or gluing.

[0062] For example, 2a Figure 6 and Figure 7As shown, in one embodiment, the intermediate bend 230 of each socket conductive terminal 200a includes a first bend 231, a first straight section 232, a second bend 233, a second straight section 234, a third bend 235, a third straight section 236, and a fourth bend 237 connected in sequence. The end of the first bend away from the first straight section is connected to the connecting interference section 260, and the end of the fourth bend away from the third straight section is connected to the contact interference section 240, so that the intermediate bend 230 of each socket conductive terminal 200a is connected to the connecting interference section 260 and the contact interference section 240 respectively. In one embodiment, the bending angle of the first bend is 110 degrees to 170 degrees, the bending angle of the second bend is 170 degrees to 200 degrees, the bending angle of the third bend is 100 degrees to 130 degrees, and the bending angle of the fourth bend is 110 degrees to 170 degrees. In this embodiment, the bending angle of the first bend is 150 degrees, the bending angle of the second bend is 180 degrees, the bending angle of the third bend is 110 degrees, and the bending angle of the fourth bend is 150 degrees. This gives the intermediate bend 230 better elasticity and allows it to better absorb the stress caused by misalignment, making the connector assembly 10 more structurally stable and avoiding the problem of easy damage and deformation of the connector assembly 10 structure, thus achieving a stable and reliable electrical connection. Specifically, the intermediate bend 230 is an R-shaped elastic deformable conductor, giving it better elasticity and allowing it to better absorb the stress caused by misalignment, making the floating of the connector assembly 10 structure more stable.

[0063] Such as 2a and Figure 6As shown, each socket conductive terminal 200a is further installed between the fixed base 210 and the floating base 220. When the plug connector 100 and the socket connector 200 are inserted and pulled out in the positive and negative directions of the Z axis, even if there is a misalignment in the positive and negative directions of the X axis and / or the positive and negative directions of the Y axis between the central axes of the two connector assemblies 10, the R-shaped elastic deformation conductor 60 can absorb the stress caused by the misalignment under the combined action of the guide post 301 of the plug connector 100 and the guide groove 801 of the socket connector 200, making the structure of the connector assembly 10 more stable and preventing structural damage or deformation of the connector assembly 10. This protects the soldering parts of the two connector assemblies 10 to the upper and lower circuit boards respectively, and realizes a stable and reliable electrical connection between the boards. In this embodiment, the shapes of the mating areas of the insulating base 100a and the socket body 200b are both frame-fitting structures. That is, the structure of the insulating base 100a mating with the socket body 200b and the structure of the socket body 200b mating with the insulating base 100a are both frame-fitting structures. This allows the mating areas of the insulating base 100a and the socket body 200b to be nested together, forming a stable frame structure. This ensures the stability of the base and its ability to withstand high temperatures, high vibrations, and large mechanical impacts during the floating process of the connector assembly 10.

[0064] like Figure 1 , Figure 8 and Figure 9 As shown, in one embodiment, the floating base 220 includes a base body 222, a first side wing 224, and a second side wing 226. The first side wing 224 and the second side wing 226 protrude from opposite sides of the base body 222. The base body 222 is located within the receiving groove 203 and is movably connected to the fixed base 210. The insertion cavity 204 is formed in the base body 222. See also... Figure 6 The maximum distance between the outline projection lines of the first side wing 224 and the second side wing 226 on the fixed base 210 in the width direction of the receiving groove 203 is greater than the width of the receiving groove 203. That is, the first extension distance of the first side wing 224 in the width direction of the fixed base 210 and the second extension distance of the second side wing 226 in the width direction of the fixed base 210 are greater than the width of the receiving groove 203. In other words, the distance between the outermost edge of the first side wing 224 and the outermost edge of the second side wing 226 in the width direction of the fixed base 210 is greater than the width of the receiving groove 203. See also... Figure 6 and Figure 10The upper half of the floating base 220 is wider than the receiving groove 203 of the fixed base 210, preventing the floating base 220 from tilting relative to the fixed base 210 when floating within the receiving groove 203. This ensures reliable contact between the plug conductive terminal 100b and the socket conductive terminal 200a, improving the electrical connection performance of the connector assembly 10. In this embodiment, the width direction of the receiving groove 203 is the Y-axis direction, the insertion / removal direction of the plug connector 100 and the socket connector 200 is the Z-axis direction, the plug conductive terminal 100b is located in the YOZ plane, and both ends of the plug conductive terminal 100b are respectively mounted on the fixed base 210 and the floating base 220. The floating base 220 can float relative to the fixed base 210 in the X, Y, and Z axis directions.

[0065] like Figure 1 , Figure 8 and Figure 9 As shown, in one embodiment, the first side wing 224 and the second side wing 226 protrude relative to each other from the outer side wall of the top of the base body 222, making the structure of the floating base 220 simpler and preventing the floating base 220 from tilting relative to the fixed base 210 when floating. To better prevent the floating base 220 from tilting relative to the fixed base 210, as... Figure 6 and Figure 10 As shown, furthermore, the length of the upper half 221 of the floating base 220 is greater than the length of the receiving groove 203 of the fixed base 210. That is, the length of the upper half of the floating base 220 in the X-axis direction is greater than the length of the receiving groove 203 of the fixed base 210 in the X-axis direction. This makes the dimension of the upper half of the floating base 220 in both the X-axis and Y-axis directions larger than the dimension of the receiving groove 203 of the fixed base 210. This avoids the problem of the upper half of the floating base 220 tilting relative to the plane of the fixed base 210 when the floating base 220 floats relative to the fixed base 210, thus preventing the upper half of the floating base 220 from tilting relative to the fixed base 210. This ensures reliable electrical connection and contact when the plug connector 100 and the socket connector 200 are mated. Figure 11 As shown, in this embodiment, the length L2 of the upper half of the floating base 220 is greater than the length of the receiving groove of the fixed base 210, and the length L2 of the upper half of the floating base is smaller than the outer perimeter length L1 of the fixed base. The width W2 of the upper half of the floating base is greater than the width of the receiving groove of the fixed base, and the width W2 of the upper half of the floating base is smaller than the outer perimeter width W1 of the fixed base. Figure 10As shown, further, the thickness of the two sides of the upper half 221 of the floating base 220 is greater than the thickness of the middle part to reinforce the structural strength of the floating base. And / or, in one embodiment, the tongue portion 204a protrudes from the top surface of the base body 222, such that the height of the tongue portion 204a is higher than the upper plane of the top of the base body 222, so that the insulating base 100a can be better connected to the floating base 220.

[0066] like Figure 12 and Figure 13 As shown, in one embodiment, the mating areas of the insulating base 100a and the socket body 200b are both frame-fitting structures, allowing the insulating base 100a and the socket body 200b to nest and interlock. This makes the connection between the mating areas of the insulating base 100a and the socket body 200b more stable, ensuring the stability of the base and its resistance to high temperatures, high vibrations, and large mechanical shocks during the floating process of the connector assembly. And / or, see also... Figure 1 and Figure 8 In one embodiment, the socket connector 200 further includes a socket soldering reinforcing foot 200c, which is connected to the socket body 200b and at least partially exposed on the outside of the socket body 200b. This allows the socket body 200b to be soldered to the circuit board via the socket soldering reinforcing foot 200c, thereby reliably fixing the socket body 200b to the circuit board. Further, the socket soldering reinforcing foot 200c forms two bent retaining feet 270, which are arranged opposite to each other and sleeved on the socket body 200b. Each bent retaining foot is used for soldering to the circuit board, connecting the socket soldering reinforcing foot 200c to the socket body 200b.

[0067] like Figure 2aAs shown, in one embodiment, the contact portion 110 of each plug conductive terminal 100b is provided with at least one contact point 112. The contact point of the contact portion 110 of each plug conductive terminal 100b abuts against the contact interference portion 240 of the corresponding socket conductive terminal 200a, so that each plug conductive terminal 100b and the corresponding socket conductive terminal 200a are reliably connected by contact. In one embodiment, the number of contact points of the contact portion 110 of each plug conductive terminal 100b is one, and the number of contact interference portions 240 of each socket conductive terminal 200a is one, so that the channel for the contact electrical connection between each socket conductive terminal 200a and the plug conductive terminal 100b has only one contact point. Each socket conductive terminal 200a has an interfering portion 240 located within a corresponding first fixing groove 206 and connected to a tongue portion 204a. The contact point of each plug conductive terminal 100b's contact portion 110 abuts against the corresponding socket conductive terminal 200a's interfering portion 240. In this embodiment, the contact portions 110 of both plug conductive terminals 100b are bent towards the side closest to the tongue portion 204a. Specifically, the contact point of each plug conductive terminal 100b's contact portion 110 is a bent protrusion, which protrudes towards the side closest to the tongue portion 204a and abuts against the interfering portion 240, so that the contact point of each plug conductive terminal 100b's contact portion 110 abuts against the corresponding socket conductive terminal 200a's interfering portion 240.

[0068] It is understood that in other embodiments, the number of contact points 112 of the contact portion 110 of each plug conductive terminal 100b is not limited to one. For example... Figure 14As shown, in one embodiment, the number of contact points 112 of the contact portion 110 of each plug conductive terminal 100b is two, namely the first contact point 112a and the second contact point 112b, so that there are only two contacts in the channel for each socket conductive terminal 200a to be electrically connected to the plug conductive terminal 100b. Each socket conductive terminal 200a has two contact interference portions 240, namely a first contact interference portion 240 and a second contact interference portion 240. The first contact interference portion 240 and the second contact interference portion 240 are arranged opposite to each other. The first contact interference portion 240 is located in the first fixing groove 206 and is connected to the tongue portion 204a. A third fixing groove 208 is formed on the inner wall of the insertion cavity 204. The third fixing groove 208 is connected to the mounting groove 202. The second contact interference portion 240 is located in the first fixing groove 206 and is connected to the inner wall of the insertion cavity 204. This allows each plug conductive terminal 100b to better contact and connect with the corresponding socket conductive terminal 200a, improving the insertion and extraction force after the plug connector 100 and the socket connector 200 are mated and increasing the number of contact points. This increases the contact robustness of the terminal contact under rapid changes in high and low temperatures, high vibration, and high mechanical shock scenarios, and further improves the contact stability of the connector assembly 10 in high temperature, high vibration, and high mechanical shock environments. In this embodiment, the contact portions 110 of both plug conductive terminals 100b are bent toward the side closer to the tongue portion 204a. Specifically, the first contact point of the contact portion 110 of each plug conductive terminal 100b is a first bending protrusion, and the second contact point is a second bending protrusion. The first bending protrusion protrudes toward the side closer to the tongue portion 204a and abuts against the first contact interference portion 240. The second bending protrusion protrudes toward the side away from the tongue portion 204a and abuts against the second contact interference portion 240, so that the contact portion 110 of each plug conductive terminal 100b more reliably abuts against the corresponding socket conductive terminal 200a.

[0069] Compared with the prior art, the present invention has at least the following advantages:

[0070] The aforementioned plug connector 100 has an insulating base 100a with a mating groove 108 and a through groove 104. The mating groove 108 and the through groove 104 are connected. The plug conductive terminal 100b is located in the mating groove 108 and connected to the insulating base 100a, thus fixing the plug conductive terminal 100b to the insulating base 100a. Furthermore, since the contact part 110 is located in the mating groove 108 and the mating groove 108 is connected to the through groove 104, the inner cavity of the insulating base is connected to the outer space of the insulating base through the slot of the through groove. This avoids the problem of the plug conductive terminal being hindered by elastic deformation when the plug connector and the socket connector are mated. At the same time, the through groove can effectively reduce the capacitance of the contact area between the plug conductive terminal and the socket conductive terminal, greatly improve the characteristic impedance of the contact area, and ensure that the characteristic impedance of the contact area meets the design requirements.

[0071] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
