Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electronic devices, and in particular to an electrical connector. Background Art
[0002] In the field of electronic devices such as electrical connectors, low-frequency current and high-frequency current have different ways of choosing the current outflow path. Low-frequency current usually chooses the path with the least resistance to flow out, while the choice of the outflow path of high-frequency current will change with the change of frequency.
[0003] Therefore, high-frequency current has higher requirements on the number of output paths and output stability of the connector to ensure efficient output of high-frequency current. Summary of the invention
[0004] In view of this, in order to solve the above problems, the present application provides an electrical connector that provides more output paths while ensuring stable output of current.
[0005] In a first aspect, the present application provides an electrical connector, comprising an insulating shell, two rows of electrical terminals and two conductive members, the insulating shell comprising a pair of oppositely arranged side walls and a docking groove located between the side walls, the electrical terminals being arranged inside the insulating shell and on both sides of the docking groove, each row of the electrical terminals comprising a plurality of power terminals and a plurality of signal terminals, the plurality of signal terminals comprising a plurality of differential pair terminals and a plurality of grounding terminals, wherein the plurality of differential pair terminals and the plurality of grounding terminals are arranged alternately; the two conductive members are mirror-symmetrical structures and are respectively mounted on the two side walls; the conductive member comprises a fixing seat and a plurality of elastic cantilevers connected to the fixing seat, the fixing seat is fixed to the side wall, the elastic cantilever passes through the side wall and is configured to abut against the grounding terminal to connect the plurality of grounding terminals.
[0006] The two conductive parts used in the present application are fixed on the side walls, and the elastic cantilever passes through the side walls into the insulating shell. The conductive parts will not damage other components in the electrical connector, and other components in the electrical connector will not affect the installation and removal of the conductive parts. The installation and removal efficiency of the conductive parts is higher; and the conductive parts are of a mirror-symmetrical structure, which reduces the structural diversity of the conductive parts. There is no need to set different production molds for the conductive parts on the two side walls. The production efficiency of the conductive parts is high, thereby reducing the mold cost for preparing the conductive parts; the conductive parts are provided with multiple elastic cantilevers, and the multiple elastic cantilevers can provide more output paths for the current. The cantilever structure of the elastic cantilever can also ensure the overlapping stability with the grounding terminal in different opening states, thereby ensuring the stable output of high-frequency current; at the same time, the cantilever structure makes the overlapped elastic cantilever closer to the contact point between the insertion card and the grounding terminal, and the high-frequency current output path is shorter, so that the current resonance point is transferred to the high-frequency band, which optimizes the impedance matching and is conducive to improving the efficiency and quality of high-frequency current output.
[0007] In a feasible embodiment, when observing a row of the electrical terminals along the length direction of the insulating shell, among the signal terminals close to the power terminals, the second signal terminal is the first grounding terminal, and the first elastic cantilever at the end of one of the conductive members passes through the side wall and is configured to abut against the first grounding terminal; when observing another row of the electrical terminals along the length direction of the insulating shell, among the signal terminals close to the power terminals, the first signal terminal is the first grounding terminal, and the fourth signal terminal is the second grounding terminal, and the first elastic cantilever at the end of another conductive member passes through the side wall and is configured to abut against the second grounding terminal.
[0008] The installation order of some of the grounding terminals in the signal terminals on both sides of the docking slot is inconsistent, that is, the grounding terminals on both sides are partially misaligned, which can reduce the electromagnetic interference between each other.
[0009] In a feasible implementation manner, the plurality of elastic cantilevers extending from the two conductive members are at the same position and are staggered from each other by two signal terminal positions on the side wall.
[0010] There is a misalignment of two signal terminals between the first grounding terminal in one row and the second grounding terminal in another row, and thus the two conductive members are installed in the above-mentioned misaligned manner, which can ensure that the two conductive members are correctly connected with the grounding terminals in the two rows of signal terminals respectively.
[0011] In a feasible implementation manner, the elastic cantilever is formed by extending obliquely upward from the inner bottom edge of the fixing seat.
[0012] The above arrangement makes the elastic cantilever and the fixing seat be arranged at an acute angle, so that when the elastic cantilever abuts against the grounding terminal, it can deform in the direction close to the fixing seat, thereby continuously applying a force to the grounding terminal away from the fixing seat to ensure the connection stability between the elastic cantilever and the grounding terminal.
[0013] In a feasible implementation manner, when the signal terminal is not actuated to deform, the elastic cantilever does not contact the corresponding ground terminal; when the signal terminal is actuated to deform, a plurality of the elastic cantilevers abut against the corresponding ground terminals one by one.
[0014] When the insertion card docking with the electrical connector is not inserted, the electrical terminal does not deform, that is, the electrical terminal does not abut against the conductive member, and the electrical connector is in a non-working state; after the insertion card is inserted into the docking slot, the electrical terminal abuts against the conductive member, and the electrical connector is in a working state, that is, through the cooperation between the insertion card and the electrical terminal, the electrical connector is switched between the working state and the non-working state, thereby ensuring the data security of the electronic device.
[0015] In a feasible implementation manner, the conductive member includes a conductive plastic member.
[0016] Conductive plastic is a plastic with conductive properties. Its dielectric constant is easier to adjust than existing materials, which is more conducive to the performance adjustment of electrical connectors. Its higher resistance can reduce the intensity of the incoming energy, thereby reducing interference with the electrical connector.
[0017] In a feasible embodiment, the signal terminal includes a fixing portion fixed to the side wall, an elastic arm extending obliquely from the fixing portion toward the docking groove, and the elastic arm has a contact portion protruding into the docking groove; the elastic cantilever passes through the side wall and is configured to abut against the elastic arm of the grounding terminal.
[0018] The contact portion extends into the docking slot, which can shorten the distance between the inserted card and the conductive member and speed up the docking process.
[0019] In a feasible implementation manner, an arc-shaped abutting portion is provided at one end of the elastic cantilever away from the fixing seat, and the arc-shaped abutting portion is configured to abut against the grounding terminal when the grounding terminal is deformed in a direction approaching the fixing seat.
[0020] The arc-shaped abutting portion is provided with an arc-shaped surface, which can increase the contact area between the elastic cantilever and the grounding terminal, disperse the contact stress, and ensure the structural integrity of the elastic cantilever; at the same time, during the deformation process of the grounding terminal, the arc-shaped surface can guide the grounding terminal to deform in a direction close to the conductive part, and automatically adjust the contact position with the grounding terminal, thereby ensuring good contact with the grounding terminal and improving the connection stability between the elastic cantilever and the grounding terminal.
[0021] In a feasible implementation manner, the electrical connector is a card edge connector that complies with the PCI Express Card Electromechanical Specification.
[0022] When the plug-in card is mated with the card edge connector, the ground terminal forms a reliable electrical connection with the plug-in card, thereby enabling signal and current flow between the plug-in card and the electronic device.
[0023] In a second aspect, the present application provides an electrical connector, comprising a longitudinal insulating shell, two rows of electrical terminals and two conductive members, the insulating shell comprising a power docking slot and a signal docking slot arranged along the longitudinal direction, each row of the electrical terminals comprising a plurality of power terminals and a plurality of signal terminals, the power terminals being arranged on both sides of the power docking slot, the signal terminals being arranged on both sides of the signal docking slot, the plurality of signal terminals comprising a plurality of differential pair terminals and a plurality of ground terminals; the two conductive members are mirror-symmetrical structures, respectively installed on both sides of the signal docking slot and electrically connected to the ground terminals one by one.
[0024] The power connection slot and the signal connection slot are arranged along the longitudinal direction, and the connection of the power terminal and the signal terminal does not interfere with each other.
[0025] In some embodiments, in two rows of electrical terminals, the first signal terminal in one row of electrical terminals is the ground terminal, the fourth signal terminal is the ground terminal, and the conductive element avoids the first signal terminal and starts connecting from the fourth signal terminal; the second signal terminal in the other row of electrical terminals is the ground terminal, and the conductive element starts connecting from the second signal terminal.
[0026] The installation order of some of the grounding terminals in the signal terminals on both sides of the signal docking slot is inconsistent, that is, the grounding terminals on both sides are partially misaligned, which can reduce the electromagnetic interference between each other.

DETAILED DESCRIPTION
[0038] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.
[0039] In the field of electronic devices such as connectors, low-frequency current and high-frequency current have different ways of selecting the current outflow path. Low-frequency current usually chooses the path with the least resistance to flow out, while the choice of the outflow path of high-frequency current will change with the change of frequency. Therefore, high-frequency current has higher requirements on the number of output paths and output stability of the connector to ensure the efficient output of high-frequency current.
[0040] In view of this, the present application provides an electrical connector 10, please refer to Figure 1 to Figure 10The electrical connector 10 includes an insulating shell 1, two rows of electrical terminals 2 and two conductive members 3. The insulating shell 1 includes a pair of oppositely arranged side walls 11 and a docking slot 14 located between the side walls 11. The electrical terminals 2 are arranged inside the insulating shell 1 and on both sides of the docking slot 14. Each row of electrical terminals 2 includes at least a plurality of power terminals 21 and a plurality of signal terminals 22. The plurality of signal terminals 22 include a plurality of differential pair terminals and a plurality of grounding terminals, wherein the plurality of differential pair terminals and the plurality of grounding terminals are arranged alternately. The electrical connector 10 is characterized in that the two conductive members 3 are mirror-symmetrical structures and are respectively installed on the two side walls 11. The conductive member 3 includes a fixed seat 31 and a plurality of elastic cantilevers 32 connected to the fixed seat 31. The fixed seat 31 is fixed to the side wall 11. The elastic cantilever 32 passes through the side wall 11 and is configured to abut against the grounding terminal to connect the plurality of grounding terminals. More specifically, the docking slot 14 of the electrical connector 10 of this embodiment includes Figure 1 The power connection slot 141 and the signal connection slot 142 are arranged along the longitudinal direction, and the power connection slot 141 and the signal connection slot 142 are spaced apart from each other. The power terminal 21 is disposed in the power connection slot 141 , and the signal terminal 22 is disposed in the signal connection slot 142 .
[0041] The two conductive members 3 used in the present application are fixed on the side wall 11, and the elastic cantilever 32 passes through the side wall 11 into the insulating housing 1. The conductive member 3 will not damage other components in the electrical connector 10, and other components in the electrical connector 10 will not affect the installation and removal of the conductive member 3, and the installation and removal efficiency of the conductive member 3 is higher; and the conductive member 3 is a mirror-symmetrical structure, which reduces the structural diversity of the conductive member 3, and there is no need to set different production molds for the conductive members 3 on the two side walls 11. The production efficiency of the conductive member 3 is high, thereby reducing the mold cost for preparing the conductive member 3; the conductive member 3 is provided with a plurality of elastic cantilevers 32, and the plurality of elastic cantilevers 32 can provide more output paths for the current. The cantilever structure of the elastic cantilever 32 can also ensure the lap stability with the ground terminal in different opening states, and ensure the stable output of high-frequency current; at the same time, the cantilever structure makes the elastic cantilever 32 after lap closer to the contact point between the insertion card 100 and the ground terminal, and the high-frequency current output path is shorter, so that the current resonance point is transferred to the high frequency band, and the impedance matching is optimized, which is conducive to improving the efficiency and quality of high-frequency current output.
[0042] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features in the following embodiments and examples can be combined with each other.
[0043] In the following, for the convenience of explanation, the transverse direction / first direction X is defined as the X-axis direction, the longitudinal direction / second direction Y is defined as the Y-axis direction, the third direction Z is defined as the Z-axis direction, and the first direction X, the second direction Y and the third direction Z are orthogonal to each other.
[0044] In some embodiments, please continue to refer to Figure 1~Figure 3 The insulating housing 1 is a mounting base for components such as the electrical terminal 2 and the conductive member 3. The insulating housing 1 is made of insulating material and is in a longitudinal shape. It includes a pair of longitudinal side walls 11 opposite to each other in the transverse direction / first direction X and a top wall 12 and a bottom wall 13 opposite to each other in the third direction Z. The insulating housing 1 is also provided with a docking slot 14, which is located between the two side walls 11, and the opening of the docking slot 14 passes through the top wall 12, for the insertion process of the insertion card 100. Specifically, the docking slot 14 includes a power docking slot 141 and a signal docking slot 142 arranged in the longitudinal direction, and the power docking slot 141 and the signal docking slot 142 are spaced apart from each other.
[0045] Please continue to refer to Figure 6 and Figure 7 The insulating housing 1 is also provided with two rows of terminal mounting holes 15 linearly arranged along the longitudinal direction / second direction Y, and the two ends of the terminal mounting holes 15 pass through the top wall 12 and the bottom wall 13 of the insulating housing 1 along the third direction Z. The two rows of terminal mounting holes 15 specifically include a row of first terminal holes 151 and a row of second terminal holes 152, and the first terminal holes 151 and the second terminal holes 152 are symmetrically arranged along a plane defined by the second direction Y and the third direction Z, and are respectively located on both sides of the docking groove 14 along the second direction Y, and the side openings of the first terminal hole 151 and the second terminal hole 152 are both facing the docking groove 14, so that the first terminal hole 151 and the second terminal hole 152 are connected to the docking groove 14 along the second direction Y. For understanding, please refer to Figure 4 and Figure 5 The first terminal hole 151 and the second terminal hole 152 are used to install the electrical terminals 2, and the two are respectively located on both sides of the docking slot 14 along the second direction Y, and the first terminal hole 151 and the second terminal hole 152 are both connected to the docking slot 14, so that after the insertion card 100 is docked with the docking slot 14, the part of the electrical terminals 2 extending into the docking slot 14 in the first terminal hole 151 and the second terminal hole 152 can be connected to the insertion card 100, thereby realizing reliable electrical connection and stable signal transmission between the insertion card 100 and the electrical connector 10.
[0046] In some embodiments, please continue to refer to Figure 4 and Figure 5 The two rows of terminal mounting holes 15 are used to mount two rows of electrical terminals 2. Please continue to refer to Fig. 9The electrical terminal 2 includes a fixing portion 221 fixed to the side wall 11, an elastic arm 222 extending obliquely from one end of the fixing portion 221 toward the docking groove 14, and a welding arm 223 extending from the other end of the fixing portion 221 toward the side wall 11, and the elastic arm 222 has a contact portion 2221 protruding into the docking groove 14. It can be understood that when the electrical terminal 2 is installed in the terminal mounting hole 15, the fixing portion 221 is accommodated inside the terminal mounting hole 15; at least part of the welding portion passes through the terminal mounting hole 15 and is exposed outside the bottom wall 13 of the insulating shell 1, and is used to reliably electrically connect the electrical terminal 2 with other circuit elements, such as wires, pads, etc. through a welding process; the contact portion 2221 of the elastic arm 222 extends into the docking groove 14, which can shorten the docking distance between the insertion card 100 and the conductive member 3 and speed up the docking process, that is, through the setting of the contact portion 2221, the grounding terminal can receive the force of the insertion card 100 in the docking groove 14 more quickly, so that the elastic arm 222 can be deformed in the direction close to the side wall 11 and contact the conductive member 3 installed on the side wall 11.
[0047] Each row of electrical terminals 2 includes multiple power terminals 21 and multiple signal terminals 22. The multiple signal terminals 22 include multiple differential pair terminals, multiple ground terminals and other signal terminals 22. Two adjacent differential pair terminals constitute a differential terminal pair. The differential pair terminals are used to transmit differential signals, that is, a pair of signals with opposite phases and the same amplitude. The ground terminal is used to provide a return path for the current.
[0048] A plurality of differential pair terminals and a plurality of ground terminals and other signal terminals 22 are alternately installed in the terminal mounting holes 15 along the second direction Y. Specifically, when observed along the second direction Y, each row of terminal mounting holes 15 includes a first part and a second part, the first part is located on both sides of the power docking groove 141, and the second part is located on both sides of the signal docking groove 142. A plurality of power terminals 21 are installed in the first part, and a plurality of differential pair terminals and a plurality of ground terminals and other signal terminals 22 are alternately installed in the second part. The present application does not limit the number of terminal mounting holes 15 included in the first part and the second part, which can be selected according to actual needs. Optionally, the first to eleventh terminal mounting holes 15 in each row are the first part, which are used to install the power terminals 21, and the terminal mounting holes 15 starting from the twelfth in each row are the second part, which are used to install the signal terminals 22.
[0049] It should be noted that the multiple power terminals 21, multiple grounding terminals and multiple differential pair terminals of the present application are all terminals with the same structure and material, and only the different installation positions of the terminal mounting holes 15 make the electrical functions of the three different. Among them, the power terminal 21 is installed in the power docking slot 141. In practice, part of the power terminal 21 transmits large current, and part of it transmits detection signals, etc. The signal terminal is installed in the signal docking slot 142, which is mainly a differential pair terminal and a grounding terminal, and also includes other low-frequency signal terminals such as detection terminals.
[0050] The present application does not limit the alternating order of the plurality of differential pair terminals and the plurality of ground terminals and other signal terminals 22 in each row of terminal mounting holes 15, and can be selected according to actual needs. Figure 3 In the present application, when observing a row of electrical terminals 2 along the length direction of the insulating housing 1, among the signal terminals 22 close to the power terminal 21, the second signal terminal 22 is the first grounding terminal, that is, the thirteenth electrical terminal 2 is the first grounding terminal; when observing another row of electrical terminals 2 along the length direction of the insulating housing 1, among the signal terminals 22 close to the power terminal 21, the first signal terminal 22 is the first grounding terminal, that is, the twelfth electrical terminal 2 is the first grounding terminal, and the fourth signal terminal 22 is the second grounding terminal, that is, the fifteenth electrical terminal 2 is the second grounding terminal. It can be understood that the same number of signal terminals 22 with the same arrangement are installed in the second parts of the first terminal hole 151 and the second terminal hole 152, and only the installation order of some of the grounding terminals in the signal terminals 22 on both sides of the docking slot 14 is inconsistent, that is, there is a partial misalignment of the grounding terminals on both sides, which can reduce the electromagnetic interference between each other; and the physical structure is designed to prevent operational errors. When the electrical connector 10 is docked with the insertion card 100, the insertion card 100 must be inserted in the correct direction to complete the connection with the electrical connector 10, thereby effectively avoiding circuit damage caused by misinsertion.
[0051] It should be noted that the two rows of electrical terminals 2 include a plurality of grounding terminals in addition to the first grounding terminal and the second grounding terminal. The present application does not limit the installation positions of the plurality of grounding terminals, which can be selected according to actual needs. Optionally, the electrical connector 10 used in the present application is a card edge connector that complies with the PCI Express Card Electromechanical Specification, and the arrangement structure of the plurality of grounding terminals complies with the design requirements of the card edge connector that complies with the PCI Express Card Electromechanical Specification.
[0052] In some embodiments, please continue to refer to Figure 2 and Figure 3The conductive member 3 for connecting the plurality of first terminals and the plurality of second terminals is installed on the side wall 11 of the insulating housing 1, and the conductive members 3 installed on the two side walls 11 are of a mirror-symmetrical structure. It can be understood that when the conductive member 3 is installed or removed from the side wall 11 of the insulating housing 1, the conductive member 3 will not damage other components in the connector, and other components in the connector will not affect the installation and removal of the conductive member 3, and the installation and removal efficiency of the conductive member 3 is higher; and the conductive members 3 installed on the two side walls 11 are of a mirror-symmetrical structure, which reduces the structural diversity of the conductive member 3, and there is no need to set different production molds for the conductive members 3 on the two side walls 11, the production efficiency of the conductive member 3 is high, thereby reducing the mold cost for preparing the conductive member 3.
[0053] Specifically, the first side wall 11 and the second side wall 11 of the insulating housing 1 are respectively provided with mounting grooves 111, and the mounting grooves 111 of the two side walls 11 are partially staggered along the second direction Y; the bottom of the mounting groove 111 is provided with a mounting through hole 1111, and the mounting through hole 1111 communicates with the mounting groove 111 and at least part of the terminal mounting hole 15. It can be understood that the mounting grooves 111 are respectively provided on the two side walls 11, and after the conductive member 3 is embedded and installed in the mounting grooves 111, the recessed structure of the mounting grooves 111 makes the side wall 11 have no protruding structure, does not increase the volume of the insulating housing 1, and the installation of the conductive member 3 is more stable.
[0054] Please continue to refer to Figure 8 The conductive member 3 includes a fixed seat 31 and a plurality of elastic cantilevers 32 connected to the fixed seat 31, both of which are made of conductive materials. The elastic cantilever 32 is formed by extending upward from the inner bottom edge of the fixed seat 31, and the elastic cantilever 32 includes a connecting member 321 and an elastic member 322 connected to each other, and the elastic member 322 is connected to the fixed seat 31 through the connecting member 321. It can be understood that the above arrangement makes the elastic cantilever 32 and the fixed seat 31 arranged at an acute angle, that is, the elastic member 322 and the connecting member 321 are arranged at an acute angle, so that when the elastic cantilever 32 abuts against the elastic arm 222 of the grounding terminal, it can be deformed in the direction close to the fixed seat 31, and then continuously exerts a force on the grounding terminal in the direction away from the fixed seat 31, so as to ensure the connection stability between the elastic cantilever 32 and the grounding terminal.
[0055] An arcuate abutment portion 3221 is provided at one end of the elastic member 322 away from the connecting member 321, and the arcuate abutment portion 3221 is configured to guide the elastic arm 222 of the grounding terminal to deform in a direction close to the fixing seat 31. It can be understood that the arcuate abutment portion 3221 is provided with an arcuate surface, and the arcuate surface can increase the contact area between the elastic member 322 and the contact portion 2221 of the elastic arm 222, disperse the contact stress, and ensure the structural integrity of the elastic member 322; at the same time, during the deformation process of the elastic arm 222, the arcuate surface can guide the elastic arm 222 to deform in a direction close to the conductive member 3, and automatically adjust the contact position with the grounding terminal, ensure good contact with the grounding terminal, and improve the connection stability between the elastic cantilever 32 and the grounding terminal.
[0056] In actual use, when the conductive member 3 is fixed to the side wall 11 and the signal terminal 22 is not deformed by the insertion card 100, the elastic cantilever 32 does not contact the corresponding ground terminal; when the signal terminal 22 is deformed, the multiple elastic cantilevers 32 abut against the corresponding ground terminals one by one. It can be understood that when the insertion card 100 docking with the electrical connector 10 is not inserted, the electrical terminal 2 does not deform, that is, the electrical terminal 2 does not abut against the conductive member 3, and the electrical connector 10 is in a non-working state; after the insertion card 100 is inserted into the docking slot 14, the electrical terminal 2 abuts against the conductive member 3, and the electrical connector 10 is in a working state, that is, through the cooperation between the insertion card 100 and the electrical terminal 2, the switching of the electrical connector 10 between the working state and the non-working state is realized, thereby ensuring the data security of the electronic device 200.
[0057] Furthermore, the mirror structure makes the multiple elastic cantilevers 32 extending from the two conductive parts 3 have the same position points, and there is a partial misalignment in the installation of the two conductive parts 3 on the side wall 11, so that the elastic cantilevers 32 are staggered from each other by two signal terminals 22 on the side wall 11. After the two conductive parts 3 are installed, the first elastic cantilever 32 at the end of one conductive part 3 can pass through the side wall 11 and abut against the first grounding terminal of a row of electrical terminals 2, the first elastic cantilever 32 at the end of the other conductive part 3 passes through the side wall 11 and abuts against the second grounding terminal of another row of electrical terminals 2, and the conductive cantilevers of the remaining parts of the conductive part 3 are connected one by one with multiple grounding terminals.
[0058] It should be noted that the length of the elastic cantilever 32 of the conductive member 3 of the present application can be selected according to actual needs and is not limited here. Optionally, after the conductive member 3 is installed and the signal terminal 22 is deformed, the contact position of the elastic cantilever 32 and the ground terminal is the first contact point, and the contact position of the ground terminal and the insertion card 100 is the second contact point, and the first contact point and the second contact point are approximately at the same height in the third direction Z, so that the output path of the current is shorter.
[0059] As an optional technical solution of the present application, the elastic member 322, the connecting member 321 and the fixing seat 31 of the present application can be an integrally formed structure, or a combined structure. Among them, the combined structure includes bonding, welding or detachable connection, etc. It can be understood that when the elastic member 322, the connecting member 321 and the fixing seat 31 are an integrally formed structure, a bonding structure or a welding structure, the overall strength of the insulating shell 1 is high and the service life is longer; when the elastic member 322, the connecting member 321 and the fixing seat 31 are a detachable structure, such as the matching connection of the clamping block and the clamping groove, when one of the elastic member 322, the connecting member 321 and the fixing seat 31 is damaged, it can be replaced separately, which reduces the maintenance cost of the electrical connector 10. Optionally, the elastic member 322, the connecting member 321 and the fixing seat 31 of the present application are an integrally formed structure.
[0060] The conductive part 3 used in the present application includes a conductive plastic part. It can be understood that the conductive plastic is a plastic with conductive properties. Its dielectric constant is easier to adjust than that of existing materials, which is more conducive to the performance adjustment of the electrical connector 10. Its higher resistance can reduce the intensity of the incoming energy, thereby reducing interference with the electrical connector 10.
[0061] In actual application, please continue to refer to Figure 4 and Figure 5 The insertion card 100 with contact points is docked with the electrical connector 10 through the docking slot 14, and as the insertion card 100 is inserted, multiple contact points of the insertion card 100 apply force to the contact portion 2221 of the ground terminal, so that the multiple elastic arms 222 move away from the insertion card 100 and abut against the multiple elastic cantilevers 32 of the conductive member 3. The elastic cantilevers 32 provide more outflow paths, and the elastic cantilevers 32 continue to apply force to the ground terminal to ensure the overlapping stability of the three under different opening states of the ground terminal, so as to achieve reliable electrical connection and stable signal transmission between the insertion card 100 and the electrical connector 10.
[0062] In some embodiments, the electrical connector 10 of the present application can be applied to electronic devices, including but not limited to computers, mobile phones, displays, external storage devices or cameras, which can be selected according to actual needs and are not limited here. Fig.10 The calculator includes a central processing unit 201, a graphics processor 202 and a display module 203. When the computer needs to execute a graphics instruction, the central processing unit 201 sends an instruction to the graphics processor 202. These instructions and related data are efficiently transmitted to the graphics processor 202 through the electrical connector 10. After receiving the instruction, the graphics processor 202 starts to process the graphics data and outputs the processing result to the display module 203 of the calculator. In the above processing process, the electrical connector 10 can realize the efficient transmission of high-frequency electrical signals.
