Description

Technical Field

[0001] The present application relates to the technical field of electrical connectors, and in particular to a conductive terminal, a wire end connector, and an electrical connector combination. Background Art

[0002] The line end connector generally realizes electrical connection through the elastic contact of the conductive terminal (such as a crown spring, a leaf spring, a torsion spring and other structures). In the related art, the elastic contact point of the conductive terminal is generally located in the middle of its body. In order to meet the needs of high current circuits, technicians need to increase the length of the conductive terminal so that the elastic contact point of the conductive terminal moves forward, thereby increasing the thickness of the conductor in the line end connector. However, due to the increase in the length of the conductive terminal, the volume of the line end connector will also increase, which is not conducive to the miniaturization of the electrical connection combination. Summary of the invention

[0003] In view of this, it is necessary to provide a conductive terminal, a wire end connector and an electrical connection assembly to improve the technical problems that the existing conductive terminals are large in size and the electrical connection assembly is difficult to miniaturize.

[0004] One embodiment of the present application provides a conductive terminal. The conductive terminal includes a base and an elastic arm. The base is constructed in a ring shape. There are multiple elastic arms, and the multiple elastic arms are distributed along the circumference of the base to form a docking space. The docking space is configured for the board-end connector to be plugged in. The elastic arm includes a connecting section and a contact section, the connecting section is connected to the base, and the contact section is connected to an end of the connecting section away from the base. Along the axial direction of the base, the connection between the connecting section and the contact section is closer to the axis of the base than the connection between the connecting section and the base, and the contact section is configured to be able to move away from or approach the axis of the base along the radial direction of the base.

[0005] In the above-mentioned conductive terminal, by setting the contact section of the elastic arm at its end, that is, at the end of the connecting section away from the base, the conductor thickness of the line end connector can be increased without changing the overall length of the conductive terminal to meet the use of high current circuits, which is conducive to the miniaturized design of the electrical connection combination.

[0006] In some embodiments of the present application, the elastic arm includes a plurality of first elastic arms and a plurality of second elastic arms. The first elastic arms and the second elastic arms are alternately distributed along the circumference of the substrate to form a docking space. A gap space is formed between two adjacent first elastic arms, and along the radial direction of the substrate, the second elastic arm is located on the side of the gap space facing the axis of the substrate.

[0007] By adopting the method of staggered arrangement of elastic arms, it is beneficial to increase the number of elastic arms in the conductive terminal, avoid the waste of the gap space between two adjacent first elastic arms, and improve the utilization rate of the conductive terminal. In addition, due to the increase in the number of elastic arms, the contact points between the conductive terminal and the conductive member in the line end connector will also increase, which is beneficial to reduce the contact resistance of the conductive terminal, reduce the temperature rise of the conductive terminal, and meet the large current demand.

[0008] In some embodiments of the present application, a first avoidance gap is formed between the first elastic arm and the second elastic arm along the radial direction of the base.

[0009] By setting the first avoidance gap, it is helpful to reduce the risk of motion interference between the adjacent first elastic arms and the second elastic arms, and ensure the stability and safety of the conductive terminal. When the board-end connector is plugged into the conductive terminal, the first elastic arm and the second elastic arm move in a direction away from the axis of the base under the action of an external force, and the first avoidance gap can provide a moving distance for the second elastic arm, that is, avoid the second elastic arm.

[0010] In some embodiments of the present application, the connecting section includes a straight portion and a bent portion connected to the straight portion, and the straight portion and the bent portion are distributed along the axial direction of the substrate. In the first elastic arm, the straight portion is connected to the substrate, and the bent portion is connected to the contact section. In the second elastic arm, the straight portion is connected to the contact section, and the bent portion is connected to the substrate. By setting the straight portion and the bent portion, a gap space and a first avoidance gap are formed in the conductive terminal.

[0011] In some embodiments of the present application, along the radial direction of the substrate, the distance between the lowest point of the contact segment in the first elastic arm and the axis of the substrate is L1, and the distance between the lowest point of the contact segment in the second elastic arm and the axis of the substrate is L2, and L1=L2.

[0012] By setting the lowest point of the contact segment in the first elastic arm and the lowest point of the contact segment in the second elastic arm to be on the same loop line, when the board-end connector is plugged into the conductive terminal, the first elastic arm and the second elastic arm can move synchronously in a direction away from the axis of the base, which is beneficial to further reduce the risk of interference between adjacent first elastic arms and second elastic arms.

[0013] In some embodiments of the present application, a second avoidance gap is formed between adjacent first elastic arm middle contact segments and second elastic arm middle contact segments along the circumference of the base.

[0014] By setting the second avoidance gap, it is helpful to reduce the risk of friction and interference between the adjacent contact segments in the first elastic arm and the second elastic arm due to the lowest point of the contact segment in the first elastic arm and the lowest point of the contact segment in the second elastic arm being on the same loop line, thereby further reducing the risk of interference between the adjacent first elastic arms and the second elastic arms.

[0015] In some embodiments of the present application, the base and the elastic arm are constructed as an integral structure.

[0016] By configuring the base and the elastic wall as an integrated structure, it is beneficial to improve the structural strength of the connection between the elastic arm and the base, and it is also beneficial to simplify the production steps. Technicians do not need to assemble the base and the elastic arm, thereby improving production efficiency.

[0017] An embodiment of the present application provides a line end connector for adapting to a board end connector. The line end connector includes a conductive member and a conductive terminal as described in any of the above embodiments. The conductive member is configured to be connected to a cable, and the conductive member is provided with an assembly groove. The conductive terminal is installed in the assembly groove. In the assembly groove, the base is connected to the conductive member, and the gap between the elastic arm and the groove wall of the assembly groove is distributed.

[0018] In the above-mentioned wire-end connector, the above-mentioned conductive terminal is used. When the wire-end connector and the board-end connector are plugged into each other, the contact section of the elastic arm in the conductive terminal can be away from the axis of the substrate in the radial direction of the substrate and contact the conductive member to achieve electrical connection between the circuit board and the cable. By arranging the contact section of the elastic arm at its end, that is, at the end of the connecting section away from the substrate, the conductor thickness of the wire-end connector can be increased without changing the overall length of the conductive terminal to meet the use of high-current circuits, which is conducive to the miniaturized design of the wire-end connector, and further conducive to the miniaturized design of the electrical connection combination.

[0019] In some embodiments of the present application, the line end connector further includes a fixing member, which is installed in the assembly groove and connected to the conductive member. The fixing member is provided with a first mounting portion, and the base is provided with a second mounting portion, and the first mounting portion cooperates with the second mounting portion to connect the conductive terminal to the fixing member.

[0020] When assembling the line-end connector, the technician can install the conductive terminal on the fixing member through the first installation part and the second installation part, and then install the fixing member with the conductive terminal installed in the assembly groove of the conductive member. This is conducive to reducing the risk of deformation and damage of the elastic arm of the conductive terminal during the assembly process of the line-end connector, improving the installation efficiency of the conductive terminal, and is conducive to improving the stability of the installation of the conductive terminal.

[0021] One embodiment of the present application provides an electrical connection combination. The electrical connection combination includes a board-end connector and the above-mentioned wire-end connector. The board-end connector is configured to be connected to a circuit board. The board-end connector is provided with a plug-in section, and the plug-in section is configured to be plugged into the docking space of the conductive terminal and to be moved out of the docking space of the conductive terminal. When the plug-in section is plugged into the docking space, the contact section moves away from the axis of the substrate along the radial direction of the substrate and contacts the conductive member. When the plug-in section moves out of the docking space, the contact section moves close to the axis of the substrate along the radial direction of the substrate and is separated from the conductive member.

[0022] In the above-mentioned electrical connection combination, by setting the contact section of the elastic arm in the conductive terminal at its end, that is, at the end of the connection section away from the substrate, the conductor thickness of the line end connector can be increased without changing the overall length of the conductive terminal to meet the use of high current circuits, which is conducive to the miniaturized design of the electrical connection combination.

[0062] 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.

[0063] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0064] The line-end connector generally realizes electrical connection through the elastic contact of conductive terminals (such as crown springs, leaf springs, torsion springs, etc.). The board-end connector is installed on the circuit board in the chassis, and the line-end connector is connected to the board-end connector to realize signal transmission.

[0065] With the rapid development of the server industry, product miniaturization has become a trend. In the related art, the elastic contact point of the conductive terminal is generally located in the middle of its body. In order to meet the needs of high-current circuits, technicians need to increase the length of the conductive terminal to move the elastic contact point of the conductive terminal forward, thereby increasing the conductor thickness in the line end connector. However, due to the increase in the length of the conductive terminal, the volume of the electrical connection combination will also increase, which makes it difficult to miniaturize the electrical connection combination.

[0066] One embodiment of the present application provides a conductive terminal. The conductive terminal includes a base and an elastic arm. The base is constructed in a ring shape. There are multiple elastic arms, and the multiple elastic arms are distributed along the circumference of the base to form a docking space. The docking space is configured for the board-end connector to be plugged in. The elastic arm includes a connecting section and a contact section, the connecting section is connected to the base, and the contact section is connected to an end of the connecting section away from the base. Along the axial direction of the base, the connection between the connecting section and the contact section is closer to the axis of the base than the connection between the connecting section and the base, and the contact section is configured to be able to move away from or approach the axis of the base along the radial direction of the base.

[0067] In the above-mentioned conductive terminal, by setting the contact section of the elastic arm at its end, that is, at the end of the connecting section away from the base, the conductor thickness of the line end connector can be increased without changing the overall length of the conductive terminal to meet the use of high current circuits, which is conducive to the miniaturized design of the electrical connection combination.

[0068] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0069] An embodiment of the present application provides an electrical connection assembly 100, in particular an electrical connection assembly capable of transmitting large currents. Large currents specifically refer to currents above 10A. The electrical connection assembly 100 is used to electrically connect multiple electrical devices (not shown), for example, a computer display screen and a computer host.

[0070] See also Figure 1 In some embodiments, the electrical connection combination 100 includes a wire-end connector 10 and a board-end connector 20, the wire-end connector 10 is configured to be connected to a cable 200, the board-end connector 20 is configured to be connected to a circuit board (not shown), and the board-end connector 20 is adapted to the wire-end connector 10.

[0071] Specifically, the board-end connector 20 is provided with a plug-in section 21, which is configured to be plugged into the line-end connector 10 or removed from the line-end connector 10. When the plug-in section 21 is plugged into the line-end connector 10, the cable 200 is connected to the circuit board; when the plug-in section 21 is separated from the line-end connector 10, the cable 200 is disconnected from the circuit board.

[0072] The arrangement of the line-end connector 10 and the board-end connector 20 facilitates the connection or disconnection between multiple electrical devices.

[0073] Please refer to Figure 2 and Figure 3 In some embodiments, the line end connector 10 includes a conductive terminal 11 and a conductive member 12. The conductive member 12 is configured to be connected to the cable 200, and the conductive member 12 is provided with a mounting groove 121, and the conductive terminal 11 is installed in the mounting groove 121. The plug section 21 is plugged into the conductive terminal 11 or removed from the conductive terminal 11.

[0074] It can be understood that when the plug section 21 is plugged into the conductive terminal 11, the conductive terminal 11 contacts the conductive member 12 to achieve electrical connection between the cable 200 and the circuit board. When the plug section 21 is removed from the conductive terminal 11, the conductive terminal 11 and the conductive member 12 separate to disconnect the electrical connection between the cable 200 and the circuit board.

[0075] Please refer to Figures 3 to 5 In some embodiments, the conductive terminal 11 includes a base 111 and an elastic arm 112. The base 111 is configured as a ring, and the base 111 is connected to the conductive member 12 in the assembly groove 121 to achieve connection between the conductive terminal 11 and the conductive member 12.

[0076] Exemplarily, the base 111 is a circular ring, the conductive member 12 is provided with a mounting groove 121 adapted to the circular ring, the circular ring is installed in the mounting groove 121 and connected to the conductive member 12 .

[0077] In other embodiments, the base 111 may also be a ring body of other shapes such as an elliptical ring, a rectangular ring, etc., which is not limited in the present application and those skilled in the art may choose according to actual conditions.

[0078] In some embodiments, there are multiple elastic arms 112, which are distributed along the circumference of the base 111 and form a docking space 115. The docking space 115 is configured for the plug-in section 21 in the board-end connector 20 to plug in. The gap between the elastic arm 112 and the groove wall of the assembly groove 121 is distributed.

[0079] The elastic arm 112 includes a connecting section 1121 and a contact section 1122, wherein the connecting section 1121 is connected to the base 111, and the contact section 1122 is connected to one end of the connecting section 1121 away from the base 111. Along the axial direction of the base 111, the connection between the connecting section 1121 and the contact section 1122 is closer to the axis of the base 111 than the connection between the connecting section 1121 and the base 111, and the contact section 1122 is configured to be able to move away from or approach the axis of the base 111 along the radial direction of the base 111.

[0080] It can be understood that when the plug-in section 21 is plugged into the docking space 115, the plug-in section 21 squeezes the elastic arm 112, and the elastic arm 112 is elastically deformed under the force. The contact section 1122 moves away from the axis of the substrate 111 along the radial direction of the substrate 111 and contacts the conductive member 12. At this time, the circuit board and the cable 200 are connected. When the plug-in section 21 is moved out of the docking space 115, the contact section 1122, under the action of the elastic force, moves close to the axis of the substrate 111 along the radial direction of the substrate 111 and separates from the conductive member 12. At this time, the circuit board and the cable 200 are disconnected.

[0081] By setting the contact section 1122 at the end of the elastic arm 112 (that is, at the end of the connecting section 1121 away from the base 111), the conductor thickness of the line end connector 10 can be increased without changing the overall length of the conductive terminal 11 to meet the use of high current circuits, which is beneficial to the miniaturized design of the electrical connection assembly 100.

[0082] It should be noted that the position of the conductive member 12 in contact with the contact segment 1122 is defined as the first position, the position of the conductive member 12 where the cable 200 is connected is defined as the second position, and the conductor thickness specifically refers to the length between the first position and the second position of the conductive member 12.

[0083] In the prior art, a blanking gap formed by processing equipment (specifically a punching machine, etc.) is usually left between two adjacent elastic arms of the conductive terminal, and the blanking gap can prevent the two adjacent elastic arms from interfering with each other during the plugging and unplugging process of the board-end connector and the line-end connector. However, due to the existence of the blanking gap, the material utilization rate of the conductive terminal is reduced, resulting in an increase in the production cost of the conductive terminal 11, and further increasing the production cost of the entire electrical connection assembly 100.

[0084] Please refer to Figure 4 and Figure 5 In some embodiments, the elastic arm 112 includes a plurality of first elastic arms 113 and a plurality of second elastic arms 114. The first elastic arms 113 and the second elastic arms 114 are alternately distributed along the circumference of the base 111 to form a docking space 115. A gap space 116 is formed between two adjacent first elastic arms 113, and along the radial direction of the base 111, the second elastic arm 114 is located on the side of the gap space 116 facing the axis of the base 111.

[0085] Specifically, the first elastic arm 113 is arranged in a ring shape around the axis of the base 111, and the second elastic arm 114 is arranged in a ring shape around the axis of the base 111. A second elastic arm 114 is arranged between two adjacent first elastic arms 113, and the second elastic arm 114 is closer to the axis of the base 111.

[0086] By adopting the staggered arrangement of the elastic arms 112, it is helpful to increase the number of elastic arms 112 in the conductive terminal 11, avoid wasting the gap space 116 between two adjacent first elastic arms 113, and improve the utilization rate of the conductive terminal 11. In addition, due to the increase in the number of elastic arms 112, the contact points between the conductive terminal 11 and the conductive member 12 in the line end connector 10 will also increase, which is helpful to reduce the contact resistance of the conductive terminal 11, reduce the temperature rise of the conductive terminal 11, and meet the large current demand.

[0087] Please refer to Figures 3 to 5 In some embodiments, a first avoidance gap 117 is formed between the first elastic arm 113 and the second elastic arm 114 along the radial direction of the base 111. When the board-end connector 20 is plugged into the conductive terminal 11, the first elastic arm 113 and the second elastic arm 114 move in a direction away from the axis of the base 111 under the action of the plug-in section 21, and the first avoidance gap 117 can provide a moving distance for the second elastic arm 114, that is, to avoid the second elastic arm 114.

[0088] The first avoidance gap 117 is provided to reduce the risk of movement interference between the adjacent first elastic arms 113 and second elastic arms 114 , thereby ensuring the stability and safety of the conductive terminal 11 .

[0089] Please refer to Figure 4 and Figure 5 In some embodiments, the connecting section 1121 includes a straight portion 11211 and a bent portion 11212 connected to the straight portion 11211. The straight portion 11211 and the bent portion 11212 are distributed along the axial direction of the base 111. In the first elastic arm 113, the straight portion 11211 is connected to the base 111, and the bent portion 11212 is connected to the contact section 1122. In the second elastic arm 114, the straight portion 11211 is connected to the contact section 1122, and the bent portion 11212 is connected to the base 111.

[0090] By disposing the straight portion 11211 and the bent portion 11212 , a gap space 116 and a first avoidance gap 117 can be formed in the conductive terminal 11 .

[0091] Exemplarily, the base 111 extends along its axial direction to form a first straight portion 1131, and one end of the first straight portion 1131 away from the base 111 is bent (i.e., convexly arranged) in a direction away from the axis of the base 111 to form a first bent portion 1132, and the first bent portion 1132 is connected to the contact section 1122. The first bent portion 1132 and the first straight portion 1131 together form the first elastic arm 113.

[0092] The base 111 is bent (i.e., recessed) in a direction close to its axis to form a second bent portion 1142. The end of the second bent portion 1142 away from the base 111 extends in the axial direction of the base 111 to form a second straight portion 1141. The second straight portion 1141 is connected to the contact section 1122. The second bent portion 1142 and the second straight portion 1141 together form the second elastic arm 114.

[0093] Please refer to Figure 4 and Figure 5 In some embodiments, along the radial direction of the substrate 111, the distance between the lowest point of the contact segment 1122 in the first elastic arm 113 and the axis of the substrate 111 is L1, and the distance between the lowest point of the contact segment 1122 in the second elastic arm 114 and the axis of the substrate 111 is L2, and L1=L2.

[0094] It should be noted that the lowest point of the contact segment 1122 specifically refers to the portion of the contact segment 1122 that is closest to the axis of the base body 111 along the radial direction of the base body 111 .

[0095] When the board connector 20 is plugged into the conductive terminal 11 , the first elastic arm 113 and the second elastic arm 114 move synchronously in a direction away from the axis of the base 111 to ensure that the first avoidance gap 117 along the radial direction of the base 111 always exists.

[0096] By arranging the lowest point of the contact segment 1122 in the first elastic arm 113 and the lowest point of the contact segment 1122 in the second elastic arm 114 to be on the same loop line, the risk of interference between the adjacent first elastic arms 113 and second elastic arms 114 can be further reduced.

[0097] In other embodiments, the lowest point of the contact segment 1122 in the first elastic arm 113 and the lowest point of the contact segment 1122 in the second elastic arm 114 may not be on the same loop, that is, L1≠L2. When the board connector 20 is plugged into the conductive terminal 11, the first elastic arm 113 and the second elastic arm 114 do not move synchronously.

[0098] For example, the second elastic arm 114 moves first and the first elastic arm 113 moves later, or the first elastic arm 113 moves first and the second elastic arm 114 moves later. This application does not limit this, and those skilled in the art can make a choice according to actual conditions.

[0099] Since the deformation of the elastic arm 112 is mainly on the contact segment 1122, that is, the deformation of the contact segment 1122 is larger, when the first elastic arm 113 and the second elastic arm 114 move synchronously in a direction away from the axis of the base 111, two adjacent contact segments 1122 are prone to relative movement.

[0100] At the same time, since the lowest point of the contact segment 1122 in the first elastic arm 113 and the lowest point of the contact segment 1122 in the second elastic arm 114 are on the same loop, when two adjacent contact segments 1122 move relative to each other, the two adjacent contact segments 1122 will generate friction to hinder the relative movement between the two adjacent contact segments 1122, resulting in interference between the first elastic arm 113 and the second elastic arm 114.

[0101] Please refer to Figure 4 and Figure 5 In some embodiments, along the circumference of the base 111 , a second avoidance gap 118 is formed between the contact segment 1122 in the adjacent first elastic arm 113 and the contact segment 1122 in the adjacent second elastic arm 114 .

[0102] The second avoidance gap 118 is provided to reduce the risk of interference between the contact segments 1122 in the adjacent first elastic arms 113 and the contact segments 1122 in the adjacent second elastic arms 114 , and further reduce the risk of interference between the adjacent first elastic arms 113 and the adjacent second elastic arms 114 .

[0103] In some embodiments, the base 111 and the elastic arm 112 are constructed as an integrated structure. By setting the base 111 and the elastic arm 112 as an integrated structure, it is helpful to improve the structural strength of the connection between the elastic arm 112 and the base 111, and it is also helpful to simplify the production steps. The technicians do not need to assemble the base 111 and the elastic arm 112, thereby improving the production efficiency.

[0104] For example, a circular ring is selected and cut axially by a cutting machine to divide the circular ring into a plurality of strip-shaped plates, and a section of the whole ring (i.e., the base 111) is reserved. Subsequently, the strip-shaped plates are bent to form the elastic arms 112. In other embodiments, casting and other methods may also be used, which are not limited in this application, and those skilled in the art may choose according to actual conditions.

[0105] Please refer to Figure 2 and Figure 3 In some embodiments, the line end connector 10 further includes a fixing member 13, which is installed in the assembly groove 121 and connected to the conductive member 12. The fixing member 13 is provided with a first mounting portion 131, and the base 111 is provided with a second mounting portion 1111. The first mounting portion 131 cooperates with the second mounting portion 1111 to connect the conductive terminal 11 to the fixing member 13.
