Abstract
Description
Technical Field
[0001] This invention relates to a connector terminal and a connector, and more particularly to a connector terminal having a conductive elastic element and being retractable, and a connector having the connector terminal. Background Technology
[0002] Currently, to achieve electrical connections between circuit boards, modules, or electronic components, a type of conductive terminal (spring pin or spring terminal) with elastic expansion and contraction function is often used. These terminals typically include a fixed conductive element, a movable conductive element, and a spring providing a restoring force, utilizing the spring's elastic pressure to maintain the stability of the electrical contact. However, when a spring current passes through, it generates a magnetic field. In high-frequency applications, the signal path is long, and there is inherent distributed capacitance (inter-turn capacitance) between adjacent coils in the spiral structure. These parasitic capacitances can form a parasitic resonant circuit with the inherent inductance of the spiral, causing it to exhibit unintended capacitive resonant characteristics and affecting the signal integrity of the conductive terminal.
[0003] Therefore, it is necessary to design a connector terminal to solve the above-mentioned technical problems. Summary of the Invention
[0004] The purpose of this invention is to provide a connector terminal and a connector that can effectively improve the resonance of the connector terminal and reduce signal distortion and delay caused by resonance.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A connector terminal includes: at least one conductive element and a conductive elastic element, wherein one of the conductive elements extends longitudinally and is provided with a mounting groove, the mounting groove passing through one end of the corresponding conductive element along the extension direction of the corresponding conductive element, the conductive elastic element being received in the mounting groove, the connector terminal being used to conduct with at least one mating member, the connector terminal being subjected to an external force and the conductive elastic element being compressed by the force, wherein one of the conductive element's mounting groove wall and one of the conductive elastic elements are provided with at least one conductive portion and at least one recessed portion opposite to the conductive portion, the conductive portion and the recessed portion being arranged along the compression direction of the conductive elastic element, the conductive portion being used to conduct with the other of the conductive element and the conductive elastic element to form an electrical connection.
[0006] Furthermore, the guide portion protrudes from the wall of the mounting groove into the mounting groove. The guide portion has a convex arc surface. The two ends of the convex arc surface and the highest point of the protrusion between them are spaced apart along the compression direction of the conductive elastic element. The convex arc surface is connected to the conductive elastic element.
[0007] Furthermore, the recess is provided with a concave arc surface, and the two ends of the concave arc surface and the lowest point of the recess between them are spaced apart along the compression direction of the conductive elastic element. The concave arc surface of the recess and the convex arc surface of the conductive part together form an undulating continuous arc surface structure.
[0008] Furthermore, one of the conductive elements has two side arms arranged side by side, with a mounting groove formed between the two side arms, and at least one of the side arms has a plurality of conductive portions and a plurality of recesses arranged alternately along the compression direction of the conductive elastic element.
[0009] Furthermore, each side arm is provided with multiple guide portions and multiple recesses arranged alternately along the compression direction of the conductive elastic element, with the guide portion of one side arm and the recess of the other side arm being laterally corresponding.
[0010] Furthermore, the connector terminal includes two conductive elements, each of which has a main body and two side arms connecting the main body. A mounting groove is formed between the two side arms. One of the two conductive elements is defined as the first conductive element and the other as the second conductive element. A contact portion is formed on the main body of the first conductive element for contacting one of the mating parts, and a conductive portion is formed on the main body of the second conductive element for conducting to the other mating part. The two side arms of the first conductive element elastically clamp the main body of the second conductive element, and the two side arms of the second conductive element elastically clamp the main body of the first conductive element, so that the first conductive element and the second conductive element form a cross-shaped structure. The mounting grooves of the first conductive element and the second conductive element together form a cross-shaped structure. In the same space that accommodates the conductive elastic element, each side arm of the first conductive element has a first guide surface at the end away from the corresponding main body. The first guide surface gradually slopes from the side of the corresponding side arm toward the mounting groove toward the other side away from the mounting groove. Each side arm of the first conductive element has a first protrusion between its end and the main body for abutting against the main body of the second conductive element. Each side arm of the second conductive element has a second guide surface at the end away from the corresponding main body. The second guide surface gradually slopes from the side of the corresponding side arm toward the mounting groove toward the other side away from the mounting groove. Each side arm of the second conductive element has a second protrusion between its end and the main body for abutting against the main body of the first conductive element.
[0011] Furthermore, the conductive portion and the recess are provided on the conductive elastic element and there are multiple of them. The conductive elastic element is a helical spring made of a metal conductive material. Each conductive portion is formed on at least one spring coil. The outer diameter of the spring coil where the conductive portion is located is larger than the outer diameter of the spring coil adjacent to the spring coil where the conductive portion is located in the compression direction of the conductive elastic element and which does not have a conductive portion.
[0012] Furthermore, the groove wall of the mounting groove has at least one sliding plane extending straight along the compression direction of the conductive elastic element. The conductive elastic element is a helical spring made of a metallic conductive material and has an actuating section located between the upper and lower ends. The outer diameter of the spring coil where the actuating section is located is the same, and the actuating section is wavy along the compression direction of the conductive elastic element. A guide portion and a recess are formed in the actuating section. The guide portion is provided in multiple places and makes lateral contact with the sliding plane to form multi-point contact.
[0013] The present invention also proposes a connector, including a base and a plurality of connector terminals as described above. The base is provided with a plurality of receiving slots, each receiving slot corresponding to a connector terminal.
[0014] Furthermore, the receiving groove includes a first groove and a second groove. Viewed along the compression direction of the conductive elastic element, the first groove and the second groove intersect in a cross shape. The connector terminal includes two conductive elements. Each conductive element has a main body, two side arms connecting the main body, and a mounting groove formed between the two side arms. One of the two conductive elements is defined as the first conductive element and the other as the second conductive element. A contact portion is formed on the main body of the first conductive element for contacting one of the mating parts. A conductive portion is formed on the main body of the second conductive element for conducting with the other mating part. The two side arms of the first conductive element elastically clamp the main body of the second conductive element, and the two side arms of the second conductive element elastically clamp the main body of the first conductive element, so that the first conductive element and the second conductive element form a cross-shaped structure. The mounting groove of the first conductive element and the mounting groove of the second conductive element together form a space for accommodating the conductive elastic element. The first conductive element is confined in the first groove, and the second conductive element is confined in the second groove.
[0015] Compared with the prior art, the connector terminals and connectors designed in this invention have the following advantages: In this invention, one of the conductive elements extends longitudinally and has a mounting groove. The mounting groove extends through one end of the corresponding conductive element along its extension direction. A conductive elastic element is housed in the mounting groove. The conductive element provides a limiting function for the conductive elastic element, and the mounting groove provides protection for the conductive elastic element. At least one conductive part and at least one recessed part are provided on the groove wall of the mounting groove of at least one conductive element and one of the conductive elastic elements, respectively, facing the other. The conductive part and the recessed part are arranged along the compression direction of the conductive elastic element, so that the conductive element and the conductive elastic element achieve point contact through the conductive part. A shorter conductive path is formed between the conductive element and the conductive elastic element, which provides a shorter flow path for current to pass through the conductive elastic element. This reduces the parasitic inductance generated by the current passing through the conductive elastic element, and significantly increases the self-resonant frequency of the connector terminal, exceeding the rated signal transmission frequency range of the connector terminal. This effectively avoids resonance phenomena within the rated signal transmission frequency range of the connector terminal, reducing signal distortion and delay caused by resonance.
[0016] The present invention also proposes a connector terminal for connecting to two mating parts, comprising: two conductive parts and a conductive elastic part. One of the two conductive parts is defined as a first conductive part and the other as a second conductive part. The first conductive part has a contact portion at one end for connecting to one of the mating parts. One end of the conductive elastic part abuts against the first conductive part, and the other end of the conductive elastic part abuts against the second conductive part. The second conductive part has a conductive portion at one end for connecting to the other mating part. The conductive elastic part is compressed by an external force. At least one of the conductive parts and the conductive elastic part has at least two conductive portions protruding laterally towards the other, spaced apart along the compression direction of the conductive elastic part. A recess is provided between any two adjacent conductive portions along the compression direction of the conductive elastic part. When the contact portion and the conductive portion are correspondingly connected to the two mating parts, and the contact portion moves relative to the conductive portion along the compression direction of the conductive elastic part to its final position, at least two conductive portions form an electrical connection with one of the conductive parts and the other of the conductive elastic part.
[0017] Furthermore, each conductive component is provided with a mounting groove, which extends in the compression direction of the conductive elastic component and passes through one of the two ends of the conductive component. The connecting part protrudes from the groove wall of the mounting groove into the mounting groove. The connecting part is provided with a convex arc surface. The two ends of the convex arc surface and the highest point of the protrusion between them are spaced apart along the compression direction of the conductive elastic component. The convex arc surface is connected to the conductive elastic component.
[0018] Furthermore, the recess is provided with a concave arc surface, and the two ends of the concave arc surface and the lowest point of the recess between them are spaced apart along the compression direction of the conductive elastic element. The concave arc surface of the recess and the convex arc surface of the conductive part together form an undulating continuous arc surface structure.
[0019] Furthermore, at least one of the conductive elements has two side arms arranged side by side, with a mounting groove formed between the two side arms, and at least one of the side arms has a plurality of conductive portions and a plurality of recesses arranged alternately along the compression direction of the conductive elastic element.
[0020] Furthermore, each side arm is provided with multiple guide portions and multiple recesses arranged alternately along the compression direction of the conductive elastic element, with the guide portion of one side arm and the recess of the other side arm being laterally corresponding.
[0021] Furthermore, the main bodies of both conductive components are formed from sheet metal. The two side arms of the first conductive component elastically clamp the main body of the second conductive component, and the two side arms of the second conductive component elastically clamp the main body of the first conductive component, forming a cross-shaped structure. The mounting grooves of the first and second conductive components together form a space to accommodate the conductive elastic component. Each side arm of the first conductive component has a first protrusion between its end furthest from the main body and the main body. The first protrusion abuts against the main body of the second conductive component. Each side arm of the second conductive component has a first protrusion between its end furthest from the main body and the main body. The first protrusion abuts against the main body of the second conductive component. A second protrusion is provided between the end of the main body and the main body, and the second protrusion is used to abut against the main body of the first conductive member; the distance between the highest point of the protrusion of any conductive part on one side arm of the first conductive member and the highest point of the protrusion of any conductive part on the other side arm in a direction perpendicular to the compression direction of the conductive elastic member is greater than the plate thickness of the side arm of the second conductive member, and / or the distance between the highest point of the protrusion of any conductive part on one side arm of the second conductive member and the highest point of the protrusion of any conductive part on the other side arm in a direction perpendicular to the compression direction of the conductive elastic member is greater than the plate thickness of the side arm of the first conductive member.
[0022] Furthermore, the conductive elastic element is a helical spring made of a metallic conductive material, and each conductive portion is formed on at least one spring coil. The outer diameter of the spring coil where the conductive portion is located is larger than the outer diameter of the spring coil adjacent to the spring coil where the conductive portion is located and which does not have a conductive portion, along the compression direction of the conductive elastic element.
[0023] Furthermore, each conductive element is provided with a mounting groove, which extends along the compression direction of the conductive elastic element and passes through one of the two ends of the conductive element. The groove wall of the mounting groove has at least one sliding plane that extends straight along the compression direction of the conductive elastic element. The conductive elastic element is a helical spring made of a metallic conductive material and has an actuating section located between its two ends. The outer diameter of the spring coil in which the actuating section is located is the same, and the actuating section is wavy along the compression direction of the conductive elastic element. The conductive part and the recess are formed in the actuating section, and multiple conductive parts make lateral contact with the sliding plane to form multi-point contact.
[0024] The present invention also proposes a connector, including a base and a plurality of connector terminals as described above. The base is provided with a plurality of receiving slots, each receiving slot corresponding to a connector terminal. The receiving slot includes a first slot and a second slot. When viewed along the compression direction of the conductive elastic element, the first slot and the second slot cross each other. The first conductive element is confined in the first slot, and the second conductive element is confined in the second slot.
[0025] Compared with the prior art, the connector terminals and connectors designed in this invention have the following advantages: In this invention, one of the conductive components and the conductive elastic component is provided with at least one conductive portion protruding laterally towards the other and at least one recessed portion recessed relative to the conductive portion. The conductive portion and the recessed portion are arranged along the compression direction of the conductive elastic component, so that the conductive component and the conductive elastic component achieve electrical contact through the conductive portion. A shorter conductive path is formed between the conductive component and the conductive elastic component, which can provide a shorter flow path for current when it passes through the conductive elastic component. This reduces the parasitic inductance generated by the current passing through the conductive elastic component, and significantly increases the self-resonant frequency of the connector terminal, which exceeds the rated signal transmission frequency range of the connector terminal. Thus, the connector terminal effectively avoids resonance phenomenon within the rated signal transmission frequency range, and reduces signal distortion and delay caused by resonance.

[0027] Explanation of reference numerals in the accompanying drawings for the specific implementation methods: Detailed Implementation To make the objectives, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] In the description of this invention, it should be noted that the terms "upper", "lower", "lateral", "width", "top", "bottom", "vertical", "inner", "outer", "middle", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the position or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.
[0029] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. It should be noted that when an element is referred to as "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intervening element.
[0030] Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," "third," or "fourth" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0031] For ease of understanding, we define the Z-axis extension direction as the up-down direction (where the positive Z-axis direction is upward), the Y-axis extension direction as the left-right direction (where the positive Y-axis direction is to the right), and the X-axis extension direction as the front-back direction (where the positive X-axis direction is forward).
[0032] like Figure 1 As shown, a connector 100 of the present invention includes a plurality of connector terminals 10 and a base 20 for receiving the plurality of connector terminals 10. The base 20 is provided with a plurality of receiving slots 201, each receiving slot 201 corresponding to one connector terminal 20. The connector 100 is used to mate with two spaced-apart mating parts 200 (see auxiliary reference). Figure 3 and Figure 9 ), Figures 2 to 7 The image shows a first embodiment of connector 100. Figures 8 to 13 The image shows a second embodiment of connector 100. Figures 14 to 17 The third embodiment of connector 100 shows only a schematic diagram of connector terminal 10. Figure 18The fourth embodiment of connector 100 shows only a schematic diagram of the structure of connector terminal 10. In these four embodiments, the main difference is in the structure of connector terminal 10, while the structure of base 20 is roughly the same. Please refer to the illustrations of the first and second embodiments.
[0033] like Figure 3 and Figure 9 As shown, in four embodiments, one end of connector terminal 20 is used to connect with one of the mating parts 200, and the other end of connector terminal 20 is used to connect with another mating part 200; one of the mating parts 200 is a circuit board, and the other mating part 200 is a chip. The chip is electrically connected to the circuit board through connector 100, so connector 100 is located between the two mating parts 200. In other embodiments, the type of mating part 200 can be selected according to the usage environment. For example, one of the mating parts 200 is a circuit board or a chip, and the other mating part 200 may be a cable or other component.
[0034] like Figure 1 As shown in the four embodiments, the seat 20 is generally rectangular, and has multiple spaced-apart receiving grooves 201 that penetrate two opposite side surfaces of the seat 20. The seat 20 is injection molded from insulating plastic material, and the receiving grooves 201 penetrate vertically, meaning they pass through the seat 20 vertically. In other embodiments, the seat 20 may be made of a combination of conductive and plastic materials, depending on the actual situation. The receiving grooves 201 may also penetrate in a front-back or left-right direction, and may be curved, with one end penetrating forward through the seat 20 and the other end penetrating downward through the seat 20.
[0035] like Figure 1 As shown, in the four embodiments, the receiving slot 201 includes a first slot 201a and a second slot 201b. When viewed along the through direction of the receiving slot 201, the first slot 201a and the second slot 201b intersect in a cross shape, so that the receiving slot 201 is approximately cross-shaped in cross section along its through direction perpendicular to its through direction.
[0036] like Figure 4 , Figure 10 , Figure 15 and Figure 18As shown, in four embodiments, the connector terminal 10 includes two conductive elements 1 and a conductive elastic element 2. One of the two conductive elements 1 is defined as a first conductive element 1a and the other as a second conductive element 1b. The first conductive element 1a is located in the first groove 201a of the corresponding receiving groove 201, and the second conductive element 1b is located in the second groove 201b of the corresponding receiving groove 201. Both the first conductive element 1a and the second conductive element 1b are made of metal sheet and are flat. One end of the conductive elastic element 2 abuts against the first conductive element 1a, and the other end of the conductive elastic element 2 abuts against the second conductive element 1b, so that the conductive elastic element 2 is compressed. In these embodiments, the conductive elastic element 2 is a helical spring made of metal conductive material, and the compression direction of the conductive elastic element 2 is the up and down direction. One end of the first conductive element 1a is used to connect with one of the mating parts 200, and one end of the second conductive element 1b is used to connect with the other mating part 200. In other embodiments, depending on the usage requirements, the compression direction of the conductive elastic element 2 can also be the front-back direction or the left-right direction. The conductive elastic element 2 can be made of other materials with conductivity and elasticity, such as conductive rubber.
[0037] like Figure 2 , Figure 8 , Figure 10 , Figure 16 and Figure 18 As shown, in the four embodiments, at least one of the conductive elements 1 extends longitudinally and is provided with a mounting groove 11. The mounting groove 11 extends through one end of the corresponding conductive element 1 along the extension direction of the corresponding conductive element 1. The elastic conductive element 1 is received in the mounting groove 11. At least one conductive part 3 and at least one recess 4 are provided on the groove wall of the mounting groove 11 of at least one conductive element 1 and one of the conductive elastic elements 2, which are laterally protruding towards the other. The conductive part 3 and the recess 4 are spaced apart along the compression direction of the conductive elastic element 2. When the connector terminal 10 is connected to the two mating parts 200, the connector terminal 10 is subjected to an external force along the compression direction of the conductive elastic element 2, and the conductive elastic element 2 is compressed. At least one conductive part 3 is connected to one of the conductive elements 1 and the conductive elastic element 2 to form an electrical connection.
[0038] like Figure 5 , Figure 6 , Figure 11 , Figure 12 , Figure 14 and Figure 18As shown, in the four embodiments, each conductive element 1 includes a main body 13 and two side arms 12. The two side arms 12 are connected to the main body 13 and arranged sideways side by side. A mounting groove 11 is formed between the two side arms 12, and the two side arms 12 are connected to the same end of the main body 13 in the compression direction (i.e., the up-down direction) of the conductive elastic element 2. The side arms 12 are cantilever structures and can elastically deform under force. The mounting groove 11 extends in the compression direction (i.e., the up-down direction) of the conductive elastic element 2 and penetrates one end of the corresponding conductive element 1. The mounting groove 11 is formed by stamping and removing part of the material on a flat metal plate. The first conductive element 1a and the second conductive element 1b form a cross structure. For example, in the above embodiments, the two side arms 12 of the first conductive element 1a can be spaced apart front to back and arranged side by side, while the two side arms 12 of the second conductive element 1b can be spaced apart left to right and arranged side by side. In other embodiments... In this embodiment, the two side arms 12 of the first conductive element 1a can be arranged side by side with a gap between them, while the two side arms 12 of the second conductive element 1b can be arranged side by side with a gap between them. The mounting groove 11 of the first conductive element 1a and the mounting groove 11 of the second conductive element 1b together form a space to accommodate the conductive elastic element 2. The top end of the conductive elastic element 2 abuts against the bottom end of the main body 13 of the first conductive element 1a between the corresponding two side arms 12. The bottom end of the conductive elastic element 2 abuts against the top end of the main body 13 of the second conductive element 1b between the corresponding two side arms 12. When the first conductive element 1a is connected to the mating part 200 located above the connector 100 and the second conductive element 1b is connected to the mating part 200 located below the connector 100, the first conductive element 1a and the second conductive element 1b are respectively subjected to external forces and move relative to each other, causing the conductive elastic element 2 to be compressed.
[0039] like Figure 5 , Figure 11 , Figure 14 and Figure 18 As shown, in the four embodiments, the side arm 12 of the first conductive member 1a is connected to one end of the corresponding main body 13, and the other end of the main body 13 of the first conductive member 1a forms a contact portion 13a, which is an arc surface. The arc surface contact portion 13a is used to contact one of the docking members 200. The side arm 12 of the second conductive member 1b is connected to one end of the main body 13, and the other end of the main body 13 of the second conductive member 1b forms a conductive portion 13b, which is also an arc surface. The arc surface conductive portion 13b is used to conduct to another docking member 200. The two side arms 12 of the first conductive member 1a are used to elastically clamp the plate surface of the main body 13 of the second conductive member 1b, and the two side arms 12 of the second conductive member 1b are used to elastically clamp the plate surface of the main body 13 of the first conductive member 1a, so that the first conductive member 1a and the second conductive member 1b form a cross structure.
[0040] like Figure 6, Figure 12 , Figure 15 and Figure 18 As shown, in four embodiments, each side arm 12 of the first conductive member 1a has a first guide surface 12a at the end away from the corresponding main body 13. The first guide surface 12a gradually slopes from the side of the corresponding side arm 12 facing the mounting groove 11 to the other side away from the mounting groove 11. Each side arm 12 of the second conductive member 1b has a second guide surface 12b at the end away from the corresponding main body 13. The second guide surface 12b gradually slopes from the side of the corresponding side arm 12 facing the mounting groove 11 to the other side away from the mounting groove 11. In some embodiments, during the installation of the first conductive member 1a and the second conductive member 1b, the ends of the two side arms 12 of the first conductive member 1a slide from the mounting groove 11 of the second conductive member 1b through the first guide surface 12a to abut against the main body 13 of the second conductive member 1b. Similarly, the ends of the two side arms 12 of the second conductive member 1b slide from the mounting groove 11 of the first conductive member 1a through the second guide surface 12b to abut against the main body 13 of the first conductive member 1a. In other embodiments, when the first conductive element 1a and the second conductive element 1b are in their normal state, the ends of the two side arms 12 of the first conductive element 1a abut against the main body 13 of the second conductive element 1b, and the ends of the two side arms 12 of the second conductive element 1b are located in the mounting groove 11 of the first conductive element 1a, but do not abut against the main body 13 of the first conductive element 1a. When the first conductive element 1a and the second conductive element 1b are subjected to external force and move relative to each other in the compression direction of the conductive elastic element 2 to their final positions, the two side arms 12 of the first conductive element 1a abut against and slide along the main body 13 of the second conductive element 1b, and the ends of the two side arms 12 of the second conductive element 1b slide from the mounting groove 11 of the first conductive element 1a to the position of the second conductive element 1b via the second guide surface 12b. The main body 13 of the first conductive element 1a abuts against the main body 13, or the ends of the two side arms 12 of the second conductive element 1b abut against the main body 13 of the first conductive element 1a. The ends of the two side arms 12 of the first conductive element 1a are located in the mounting groove 11 of the second conductive element 1b, and do not abut against the main body 13 of the second conductive element 1b. When the first conductive element 1a and the second conductive element 1b are subjected to external force and move relative to each other in the compression direction of the conductive elastic element 2 to the final position, the two side arms 12 of the second conductive element 1b abut against and slide along the main body 13 of the first conductive element 1a. The ends of the two side arms 12 of the first conductive element 1a slide from the mounting groove 11 of the second conductive element 1b through the first guide surface 12a to abut against the main body 13 of the second conductive element 1b.
[0041] like Figure 5 , Figure 11 , Figure 14 and Figure 18As shown, in the four embodiments, each side arm 12 of the first conductive member 1a has a first protrusion 14 protruding between its end and the main body 13 for abutting against the main body 13 of the second conductive member 1b. The first conductive member 1a can stably abut against the main body 13 of the second conductive member 1b through the first protrusion 14 of its two side arms 12, and / or each side arm 12 of the second conductive member 1b has a second protrusion 15 protruding between its end and the main body 13 for abutting against the main body 13 of the first conductive member 1a. The two side arms 12 of the second conductive member 1b can stably abut against the main body 13 of the first conductive member 1a through the second protrusion 15, so that the first conductive member 1a and the second conductive member 1b form an interconnected structure.
[0042] like Figure 5 , Figure 6 , Figure 11 , Figure 12 , Figure 14 , Figure 15 and Figure 18 As shown, in four embodiments, at least one conductive element 1 is provided with a slot 16, which penetrates the two plates of the corresponding main body portion 13. For example, the second conductive element 1b is provided with a slot 16. When the connector terminal 10 is in the normal state, the first protrusions 14 on the two side arms 12 of the first conductive element 1a respectively engage with the slot 16 to prevent the first conductive element 1a and the second conductive element 1b from separating from each other. When the first conductive element 1a and the second conductive element 1b are subjected to external force and move relative to each other in the compression direction of the conductive elastic element 2, the first protrusions 14 disengage from the slot 16 and move toward the conduction portion 13b and abut against the plate of the main body portion 13 of the second conductive element 1b. In other embodiments, a through slot 16 can be provided in the main body portion 13 of the first conductive element 1a for the second protrusion 15 to engage, or both the first conductive element 1a and the second conductive element 1b are provided with through slots 16 in their respective main bodies 13.
[0043] like Figure 2 and Figure 8As shown, in the first and second embodiments, the conductive portion 3 protrudes from the wall of the mounting groove 11 of the first conductive member 1a into the mounting groove 11, that is, the conductive portion 3 protrudes from the side arm 12 of the first conductive member 1a into the mounting groove 11. Both side arms 12 of the first conductive member 1a are provided with a plurality of conductive portions 3 and a plurality of recesses 4 arranged alternately along the compression direction of the conductive elastic member 2. The conductive portion 3 of one side arm 12 of the first conductive member 1a is laterally corresponding to the recess 4 of the other side arm 12. For example, the conductive portion 3 of one side arm 12 of the first conductive member 1a protrudes towards the other side arm 12, and the recess 4 of the other side arm 12 of the first conductive member 1a is recessed away from the conductive portion 3, so that in the compression direction perpendicular to the conductive elastic member 2, the conductive portion 3 and the recess 4 are located on opposite sides of the conductive elastic member 2.
[0044] like Figure 2 and Figure 8 As shown, in the first and second embodiments, the conductive part 3 is provided with a convex arc surface 31. The two ends of the convex arc surface 31 and the highest point of the protrusion between them are spaced apart in the compression direction of the conductive elastic element 2. The convex arc surface 31 is at least partially connected to the conductive elastic element 2. Between any two adjacent conductive parts 3, the recess 4 is provided with a concave arc surface 41. The two ends of the concave arc surface 41 and the lowest point of the concavity between them are spaced apart in the compression direction of the conductive elastic element 2. The concave arc surface 41 of the recess 4 and the convex arc surface 31 of the conductive part 3 together constitute a continuous arc surface structure undulating along the compression direction of the conductive elastic element 2. The continuous arc surface structure is specifically a wave-shaped structure.
[0045] like Figure 6 and Figure 12 As shown, in the first and second embodiments, the conductive elastic element 2 is made of a metal conductive material. The conductive elastic element 2 can be a cylindrical helical spring. Of course, in other embodiments, the conductive elastic element 2 can also be a serpentine metal spring or a wave-shaped metal spring.
[0046] like Figure 5 , Figure 6 , Figure 7As shown, in the first embodiment, both side arms 12 of the first conductive member 1a are provided with a plurality of conductive portions 3 and a plurality of recesses 4 arranged alternately along the compression direction of the conductive elastic member 2. Both side arms 12 of the second conductive member 1b are provided with a plurality of conductive portions 3 and a plurality of recesses 4 arranged alternately along the compression direction of the conductive elastic member 2. The distance between the highest point of the protrusion of any conductive portion 3 on one side arm 12 of the first conductive member 1a and the highest point of the protrusion of any conductive portion 3 on the other side arm 12 in a direction perpendicular to the compression direction of the conductive elastic member 2 is defined as the first distance D1. The plate thickness of the side arm 12 of the second conductive member 1b is defined as the first plate thickness T1. The first distance D1 is greater than the first plate thickness. T1, the distance between the highest point of the protrusion of any conductive part 3 on one side arm 12 of the second conductive member 1b and the highest point of the protrusion of any conductive part 3 on the other side arm 12 in a direction perpendicular to the compression direction of the conductive elastic member 2 is defined as the second distance D2. The plate thickness of the side arm 12 of the first conductive member 1a is defined as the second plate thickness T2. The second distance D2 is greater than the second plate thickness T2. The first conductive member 1a forms multi-point contact with the conductive elastic member 2 through multiple conductive parts 3 on it. At the same time, the second conductive member 1b forms multi-point contact with the conductive elastic member 2 through multiple conductive parts 3 on it. This can avoid interference between the first conductive member 1a and the second conductive member 1b when the two components move relative to each other.
[0047] like Figure 11 , Figure 12 , Figure 13 As shown, in the second embodiment, each of the two side arms 12 of the first conductive member 1a is provided with a plurality of conductive parts 3 and a plurality of recesses 4 arranged alternately along the compression direction of the conductive elastic member 2. The two side arms 12 of the second conductive member 1b are set as planar structures with their inner sides roughly along the compression direction of the conductive elastic member 2. The distance between the planar structures of the two side arms 12 of the second conductive member 1b is defined as the third distance D3. The third distance D3 is greater than the second plate thickness T2 of the first conductive member 1a, so that the conductive parts 3 of the first conductive member 1a protrude into the mounting groove 11 of the second conductive member 1b and contact the conductive elastic member 2. At the same time, interference between the first conductive member 1a and the second conductive member 1b can be avoided when the two components move relative to each other.
[0048] like Figures 14 to 17As shown, in the third embodiment, the mounting groove 11 of the first conductive member 1a has sliding planes 5 extending straight along the compression direction of the conductive elastic member 2 on both sides of the groove wall. The mounting groove 11 of the second conductive member 1b has sliding planes 5 extending straight along the compression direction of the conductive elastic member 2 on both sides of the groove wall. A plurality of conductive parts 3 are spaced apart on the conductive elastic member 2 along the compression direction of the conductive elastic member 2. The conductive elastic member 2 is a helical spring made of a metal conductive material. Each conductive part 3 is formed on at least one spring coil. The outer diameter of the spring coil where the conductive part 3 is located is larger than the outer diameter of the spring coil adjacent to the spring coil where the conductive part 3 is located in the compression direction of the conductive elastic member 2 and which does not have a conductive part 3. The space defined between the spring coil forming the conductive part 3 and the spring coil without the conductive part 3 protruding outward is the recess 4.
[0049] like Figure 18 As shown, in the fourth embodiment, the two side walls of the mounting groove 11 each have a sliding plane 5 extending straight along the compression direction of the conductive elastic element 2. The conductive elastic element 2 is a helical spring made of a conductive metal material and has an actuating section 6 located between its two ends. The outer diameter of the spring coils where the actuating section 6 is located is the same, and the actuating section 6 is wavy along the compression direction of the conductive elastic element. Multiple guide portions 3 and multiple recesses 4 are formed in the actuating section 6, and the multiple guide portions 3 and multiple recesses 4 are alternately arranged along the compression direction of the conductive elastic element 2; wherein A guide portion 3 protrudes towards one side of the groove wall of the mounting groove 11, and the actuating section 6 naturally recesses inward on the side opposite to the guide portion 3 to form a corresponding recess 4; the actuating section 6 forms multiple points of contact with the sliding plane 5 at multiple guide portions 3. When the first conductive member 1a and the second conductive member 1b are subjected to external force in the compression direction of the conductive elastic member 2, and the contact portion 13a and the conductive portion 13b move toward each other in the compression direction of the conductive elastic member 2, the conductive elastic member 2 is compressed and deformed by force, and multiple guide portions 3 slide along the sliding plane 5.
[0050] In other embodiments, the connector terminal 10 may be provided with only one conductive element 1 and one conductive elastic element 2. One of the contact portion 13a and the conductive portion 13b is provided on the conductive element 1, and the other is provided on the conductive elastic element 2. The conductive elastic element 2 is received in the mounting groove 11 of the conductive element 1. Of course, in other embodiments, the conductive elastic element 2 may be sleeved on the outside of the conductive element 1. In yet another embodiment, the conductive elastic element 2 may be sleeved on the outside of two conductive elements 1. Thus, when the conductive portion 3 and the recess 4 are provided on the conductive element 1, they are provided on the outside of the conductive element 1, for example, the two side arms 12 are away from each other's outside. Or, when the conductive portion 3 and the recess 4 are provided on the conductive elastic element 2, the conductive elastic element 2 is provided on the outside of the conductive element 1, for example, the two side arms 12 are away from each other's outside.
[0051] In summary, the connector terminals and connector of the present invention have the following beneficial effects: (1) In this invention, one of the conductive elements 1 extends longitudinally and is provided with a mounting groove 11. The mounting groove 11 extends through one end of the corresponding conductive element 1 along the extension direction of the corresponding conductive element 1. The conductive elastic element 2 is received in the mounting groove 11. The conductive element 1 provides a limiting function for the conductive elastic element 2, and the mounting groove 11 provides a protective function for the conductive elastic element 2. At least one of the groove wall of the mounting groove 11 of at least one conductive element 1 and the conductive elastic element 2 are provided with at least one guide portion 3 and at least one recess 4 that is recessed relative to the guide portion 3, and the guide portion 3 and the recess 4 are along the conductive elastic element. The compression direction setting of 2 enables point contact between conductive element 1 and conductive elastic element 2 through conductive part 3, forming a shorter conductive path between conductive element 1 and conductive elastic element 2. This provides a shorter flow path for current passing through conductive elastic element 2, reduces the parasitic inductance generated by current passing through conductive elastic element 2, and significantly increases the self-resonant frequency of connector terminal 10, exceeding the rated frequency range of signal transmission of connector terminal 10. This effectively avoids resonance phenomenon within the rated frequency range of signal transmission of connector terminal 10, reducing signal distortion and delay caused by resonance.
[0052] (2) By providing a convex arc surface 31 to the conductive part 3, the conductive part 3 can form a small area contact with the conductive elastic element 2. When the conductive elastic element 2 is compressed, the friction between the conductive part 3 and the conductive elastic element 2 is reduced. At the same time, it is ensured that the conductive element 1 forms a multi-point contact with the conductive elastic element 2 through multiple conductive parts 3 arranged at intervals. At least two conductive paths are formed between the conductive element 1 and the conductive elastic element 2, which can provide a shorter current flow path, improve the resonance generated by the conductive elastic element 2, and reduce the signal distortion and delay of the connector terminal 10 caused by the resonance.
[0053] (3) By forming a continuous arc surface structure along the compression direction of the conductive elastic element 2 by the concave arc surface 41 of the recess 4 and the convex arc surface 31 of the conductor 3, interference contact between the conductive elastic element 2 and other parts of the conductive element 1 except for the conductor 3 is avoided, and the wear of the conductive elastic element 2 and the conductive element 1 is reduced.
[0054] (4) By providing two side arms 12 arranged side by side in one of the conductive elements 1, and forming a mounting groove 11 between the two side arms 12 to accommodate the conductive elastic element 2, at least one of the side arms 12 is provided with a plurality of conductive parts 3 and a plurality of recesses 4 arranged alternately along the compression direction of the conductive elastic element 2. The recesses 4 provide deformation space for the conductive elastic element 2 to be compressed and deformed under force. Furthermore, interference contact between the conductive elastic element 2 and other parts of the conductive element 1 except for the conductive parts 3 is avoided, and the wear between the conductive elastic element 2 and the conductive element 1 is reduced.
[0055] (5) By providing a guide portion 3 and a recess 4 on each side arm 12, and making the guide portion 3 of one side arm 12 laterally corresponding to the recess 4 of the other side arm 12, the conductive elastic element 2 is subjected to asymmetrical force in any radial direction, avoiding excessive constraint that causes the conductive elastic element 2 to jam in the compression action, while ensuring that there are more contact points between the conductive element 1 and the conductive elastic element 2.
[0056] (6) The first side arm 12 abuts against the conductive part 13b of the second conductive member 1b through the first protrusion 14 at the end. The first protrusion 14 on the two opposite first side arms 12 is located on both sides of the second conductive member 1b, forming an elastic clamping effect on the second conductive member 1b. Similarly, the second side arm 12 abuts against the contact part 13a of the second conductive member 1b and the first conductive member 1a through the second protrusion 15 at the end. The second protrusion 15 on the two opposite second side arms 12 is located on both sides of the conductive part 13b of the first conductive member 1a, forming an elastic clamping effect on the second conductive member 1b, thereby improving the connection stability between the first conductive member 1a and the second conductive member 1b.
[0057] (7) By making the outer diameter of the spring coil where the conductor part 3 is located adjacent to the spring coil where the conductor part 3 is located in the compression direction of the conductive elastic element 2 and the spring coil where the conductor part 3 is located without the conductor part 3, the conductive elastic element 2 can achieve electrical conduction by multiple contact between the conductive elastic element 1 and the spring coil where the conductor part 3 is located with a larger outer diameter, providing a shorter flow path for the current to pass through the conductive elastic element 2, thereby effectively reducing the overall inductance and effectively suppressing high frequency resonance.
[0058] (8) By making an actuating segment 6 between the upper and lower ends of the conductive elastic element 2 wavy along the compression direction of the conductive elastic element 2, and forming multiple conductive parts 3 on the actuating segment 6, the actuating segment 6 and the sliding plane 5 form multiple points of contact, so that the conductive elastic element 2 can achieve electrical conduction through the actuating segment 6 and the conductive element 1 through multiple points of contact, providing a shorter current flow path, thereby effectively reducing the overall inductance and effectively suppressing high frequency resonance.
[0059] The above detailed description is only an illustration of a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
