Abstract
Description
[Technical Field]
[0001] This utility model relates to a terminal module and an electrical connector, and more particularly to a terminal module and electrical connector that can reduce crosstalk. [Background Technology]
[0002] An electrical connector, such as Chinese Patent CN202111133180.7, has a terminal with a conductive portion that connects downward to a first electronic component and a floating contact portion that connects upward to a second electronic component. It also has a fixing portion that secures the terminal within a receiving groove, and an elastic arm and a deformable arm extending from the fixing portion toward the floating contact portion and the conductive portion, respectively. The elastic arm is insulated from the floating contact portion by an insulating block and provides elasticity to the floating contact portion. The deformable arm is insulated from the conductive portion by a plastic block and provides elasticity to the conductive portion. When the terminal is electrically connected to the first and second electronic components, the signal between the first and second electronic components is transmitted through the floating contact portion and the conductive portion, without flowing through the elastic arm, the deformable arm, and the fixing portion.
[0003] However, since the fixing part, elastic arm and deformable arm of the terminal are all made of metal, although they do not transmit signals, when the conductive part and floating contact part make contact with the first electronic component and the second electronic component, an induced magnetic field will be formed around them. This induced magnetic field will cause the metal fixing part, elastic arm and deformable arm to generate induced current. This induced current will cause crosstalk to the floating contact part and conductive part, thereby affecting the signal transmission between the terminal and the first electronic component and the second electronic component.
[0004] Therefore, it is necessary to design a terminal module and electrical connector to solve the above-mentioned technical problems. [Utility Model Content]
[0005] The purpose of this invention is to provide a terminal module and electrical connector that uses insulating components to connect and position the first and second terminals, thereby avoiding signal crosstalk between the first and second terminals.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A terminal module for electrically connecting a first electronic component to a second electronic component, characterized in that it comprises: a first terminal, wherein one end of the first terminal along its length is provided with a first connecting portion and the other end is provided with a first conductive portion, and the first terminal further provides a first contact portion located between the first connecting portion and the first conductive portion for abutting upward against the first electronic component; and a second terminal, located below the first terminal and separately disposed from the first terminal, wherein one end of the second terminal along its length is provided with a second connecting portion and the other end is provided with a second conductive portion, and the second terminal further provides a second contact portion located between the second connecting portion and the second conductive portion for electrically conducting with the second electronic component. The insulating component includes an insulating fixing portion, a first insulating arm that bends and extends toward and positions the first connecting portion, and a second insulating arm that bends and extends toward and positions the second connecting portion. The second insulating arm is located below the first insulating arm, and a deformation space exists between the first and second insulating arms. When a first electronic component presses down on the first contact portion and a second electronic component electrically connects the second contact portion, the first insulating arm is compressed and elastically deforms toward the deformation space, causing the first and second conductive portions to become electrically connected. Furthermore, the path from the first contact portion through the insulating component to the second contact portion is longer than the path from the first contact portion through the first and second conductive portions to the second contact portion. Further, the first insulating arm has a separately configured first bridging section and a first extension section. The first connecting portion positions the first bridging section, and the dielectric constant of the first bridging section is smaller than that of the first extension section.
[0008] Furthermore, one end of the first bridging section covers the first connecting portion, and the other end is provided with a first snap-fit portion. The first extension section is provided with a first mating groove. The first snap-fit portion and the first mating groove are engaged to fix the first bridging section and the first extension section. The first extension section is horizontally arranged, and the first bridging section bends upward relative to the first extension section.
[0009] Furthermore, the second insulating arm has a second bridging section and a second extension section that are separately configured, and the dielectric constant of the second bridging section is smaller than that of the second extension section. One end of the second bridging section covers the second connecting portion, and the other end is provided with a second snap-fit portion. The second extension section is provided with a second mating groove. The second snap-fit portion and the second mating groove are engaged to fix the second bridging section and the second extension section. The second extension section is horizontally configured, and the second bridging section bends downward relative to the second extension section. The first insulating arm is provided with a connecting section that integrally connects the first extension section and the second extension section. The connecting section is bent and integrally connected to the upper end of the insulating fixing portion.
[0010] Furthermore, the second conductive part elastically abuts against the second electronic component downwards, and the first conductive part abuts against the second conductive part.
[0011] Furthermore, both the first terminal and the second terminal are formed by blanking, and the plate surface of the first terminal and the plate surface of the second terminal are located on the same vertical plane. The first conductive portion is farther away from the insulating member than the first contact portion, and the first conductive portion has a first inclined surface extending obliquely in the thickness direction; the second conductive portion is farther away from the insulating member than the second contact portion, and the second conductive portion has a second inclined surface extending obliquely in the thickness direction. When the first electronic component presses down on the first contact portion and the second electronic component abuts against the second contact portion upward, the first inclined surface and the second inclined surface are in contact with each other.
[0012] Furthermore, the first connecting part has a first positioning hole, and one end of the first insulating arm is injection molded to cover the first connecting part and part of the insulating material extends into the first positioning hole. The second connecting part has a second positioning hole, and one end of the second insulating arm is injection molded to cover the second connecting part and part of the insulating material extends into the second positioning hole. The first insulating arm, the second insulating arm and the insulating fixing part are integrally formed and are made of elastic plastic.
[0013] This utility model also adopts the following technical solution: an electrical connector, including an insulating body and the aforementioned terminal module, characterized in that: the insulating body is provided with a receiving groove running vertically through it, and the terminal module is received in the receiving groove. Further, a limiting protrusion is provided in the receiving groove, and a limiting groove is formed between the side wall of the limiting protrusion and the side wall of the receiving groove. The insulating fixing part is inserted into the limiting groove and interferes with the inner wall of the limiting groove. The upper surface of the limiting protrusion is lower than the upper surface of the insulating body, used to support the second insulating arm upwards. Further, the end of the second contact part away from the second connecting part extends upwards and toward the side away from the insulating fixing part with an inclined section, and an abutting section extends upwards from the upper end of the inclined section. The second conductive part is connected to the upper end of the abutting section. When the first electronic component presses down on the first contact part and the second electronic component abuts upwards against the second contact part, the side surface of the abutting section away from the insulating fixing part abuts against the inner wall of the receiving groove, and the first conductive part abuts against the second conductive part.
[0014] Compared with the prior art, the terminal module and electrical connector designed in this utility model have the following advantages:
[0015] In this invention, the first terminal abuts against the first electronic component upwards via the first contact portion, and the second terminal is electrically connected to the second electronic component downwards via the second contact portion. Furthermore, the first and second contact portions are electrically connected to each other. This allows the signal from the first electronic component to flow from the first contact portion through the first and second contact portions to the second contact portion, and finally to the second electronic component via the second contact portion. Since the path from the first contact portion through the insulating member to the second contact portion is longer than the path from the first contact portion through the first and second contact portions to the second contact portion, the signal transmission path between the first and second electronic components is shortened, which is beneficial for high frequencies. Additionally, the insulating member has a first connecting portion that bends and extends towards the first terminal and is positioned... The first insulating arm of the first connecting portion and the second insulating arm of the second connecting portion bend and extend toward the second terminal and position the second connecting portion, and there is a deformation space between the first insulating arm and the second insulating arm, so that the first terminal and the second terminal can be displaced in the vertical direction, thereby ensuring that the first terminal can conduct the first electronic component well and the second terminal can conduct the second electronic component well. Moreover, since the insulating component is made of insulating material, when the first electronic component and the second electronic component transmit signals through the first terminal and the second terminal, the induced magnetic field generated by them will not cause the plastic insulating component to generate induced current, avoiding signal crosstalk between the first terminal and the second terminal, thereby enabling stable signal transmission between the first terminal and the second terminal, which is beneficial to the high-frequency performance of the electrical connector.

Detailed Implementation Methods
[0029] To better understand the content of this utility model, a more detailed description of this utility model will now be provided in conjunction with specific implementation schemes and illustrations.
[0030] like Figures 1 to 10 As shown, the terminal module 2 and electrical connector 1000 of this utility model define a front-back direction, and a left-right direction and a top-bottom direction perpendicular to the front-back direction. For ease of understanding of the accompanying drawings, the forward direction in the front-back direction is the positive direction of the X-axis, the rightward direction in the left-right direction is the positive direction of the Y-axis, and the upward direction in the top-bottom direction is the positive direction of the Z-axis.
[0031] like Figures 1 to 6 In the first embodiment of the electrical connector 1000 of this utility model, the electrical connector 1000 has an insulating body 1 and a plurality of terminal modules 2. The insulating body 1 is provided with a plurality of receiving grooves 11 extending through the top and bottom, and the plurality of terminal modules 2 are received in the receiving grooves 11.
[0032] like Figure 1 , Figure 2 and Figure 6 As shown, each receiving groove 11 is provided with a limiting protrusion 12. The upper surface of the limiting protrusion 12 is lower than the upper surface of the insulating body 1, and a limiting groove 13 is formed between the side wall of the limiting protrusion 12 and the side wall of the receiving groove 11. The limiting groove 13 is used to limit the terminal module 2, so that the terminal module 2 is fixed in the receiving groove 11.
[0033] like Figures 1 to 3 As shown, each terminal module 2 has a first terminal 21 and a second terminal 22 located below the first terminal 21. Both the first terminal 21 and the second terminal 22 are formed by blanking, and the plate surface of the first terminal 21 and the plate surface of the second terminal 22 are located on the same vertical plane. An insulating member 23 positions the first terminal 21 and the second terminal 22.
[0034] like Figure 1, Figures 3 to 6 As shown, the first terminal 21 has a first connecting portion 211 at one end and a first conductive portion 212 at the other end along its length. The first terminal 21 also has a first contact portion 213 located between the first connecting portion 211 and the first conductive portion 212 for upward contact with the first electronic component 2000. The first connecting portion 211 is embedded in the insulating member 23 and has a first positioning hole 2111 that penetrates the first connecting portion 211 in the thickness direction of the first terminal 21. In this embodiment, there are two first positioning holes 2111 (of course, in other embodiments, the number of first positioning holes 2111 can be one, three, etc.). The first positioning holes 2111 make the first connecting portion 211 more stably fixed to the insulating member 23. The first conductive portion 212 is farther away from the insulating member 23 than both the first connecting portion 211 and the first contact portion 213, and is used to contact the second terminal 22. The first conductive portion 212 also has a first inclined surface 2121 extending obliquely along the thickness direction. In this embodiment, the first inclined surface 2121 extends obliquely backward from the front surface of the first conductive portion 212 and is used to abut against the second terminal 22. The height of the lower end of the first connecting portion 211 is higher than the height of the lower end of the first conductive portion 212 in the vertical direction, so that the first connecting portion 211 has a shorter length, thereby reducing the stake effect generated by the first connecting portion 211. Moreover, the height of the first contact portion 213 is higher than the height of the first connecting portion 211 in the vertical direction, and the first contact portion 213 is exposed upward in the receiving groove 11, which facilitates the first contact portion 213 to be connected to the first electronic component 2000.
[0035] like Figure 1 , Figures 3 to 6As shown, the second terminal 22 is located below the first terminal 21 and is separately disposed from the first terminal 21. One end of the second terminal 22 along its length direction is provided with a second connecting portion 221, and the other end is provided with a second conductive portion 222. The second terminal 22 is also provided with a second contact portion 223 located between the second connecting portion 221 and the second conductive portion 222 for conducting the second electronic component 3000. In this embodiment, the second contact portion 223 elastically abuts against the second electronic component 3000 downward (of course, in other embodiments, the second contact portion 223 can also be conducted to the second electronic component 3000 by means of SMT or DIP). Specifically, the second connecting portion 221 is embedded in the insulating member 23, and the second connecting portion 221 has a second positioning hole 2211. The second positioning hole 2211 penetrates the second connecting portion 221 in the thickness direction of the second terminal 22. In this embodiment, there are two second positioning holes 2211 (of course, in other embodiments, the number of second positioning holes 2211 can be one, three, etc.). The setting of the second positioning hole 2211 can make the connection between the second connecting portion 221 and the insulating member 23 more stable. The end of the second contact portion 223 away from the second connecting portion 221 extends upward and toward the side away from the insulating member 23 with an inclined section 224 and an abutting section 225 extending upward from the upper end of the inclined section 224. The side surface of the abutting section 225 away from the insulating member 23 is used to abut against the inner wall surface of the receiving groove 11. The second conductive portion 222 is connected to the upper end of the abutment section 225, and the second conductive portion 222 is farther away from the insulating member 23 than the second contact portion 223, so as to abut against the first conductive portion 212 in its thickness direction. The second conductive portion 222 has a second inclined surface 2221 that extends obliquely in the thickness direction. In this embodiment, the second inclined surface 2221 extends obliquely forward from the rear surface of the second conductive portion 222 to fit against the first inclined surface 2121.
[0036] like Figure 1 , Figures 3 to 6As shown, the insulating member 23 has an insulating fixing portion 231, a first insulating arm 232 that bends and extends toward and positions the first connecting portion 211, and a second insulating arm 233 that bends and extends toward and positions the second connecting portion 221. The second insulating arm 233 is located below the first insulating arm 232, and there is a deformation space 24 between the first insulating arm 232 and the second insulating arm 233. Moreover, the second insulating arm 233, the first insulating arm 232, and the insulating fixing portion 231 are integrally formed. In this embodiment, the insulating member 23 is made of a plastic material with good elastic properties, such as silicone rubber or PA material. By injection molding one end of the first insulating arm 232 to cover the first connecting part 211 and part of the insulating material extending into the first positioning hole 2111, and by injection molding one end of the second insulating arm 233 to cover the second connecting part 221 and part of the insulating material extending into the second positioning hole 2211, the holding force between the first insulating arm 232 and the first connecting part 211 and the second insulating arm 233 and the second connecting part 221 can be increased.
[0037] like Figure 1 , Figures 3 to 6 As shown, the insulating fixing part 231 is inserted into the limiting groove 13 and interferes with the inner wall surface of the limiting groove 13, thereby allowing the entire terminal module 2 to be stably housed in the receiving groove 11. The first insulating arm 232 has a first horizontal segment 2321 and a first curved segment 2322 extending upward from one end of the first horizontal segment 2321. The first connecting part 211 is positioned at the first curved segment 2322. Since the first curved segment 2322 is curved, it can provide better elasticity for the first terminal 21. The second insulating arm 233 has a second horizontal segment 2331 and a second curved segment 2332 extending downward from one end of the second horizontal segment 2331. The second horizontal segment 2331 is located below the first horizontal segment 2321. The second connecting part 221 is positioned at the second curved segment 2332. Since the second curved segment 2332 is curved, it can provide better elasticity for the second terminal 22.
[0038] like Figures 1 to 6As shown, when the first electronic component 2000 presses down on the first contact portion 213 and the second electronic component 3000 abuts upward against the second contact portion 223, the first insulating arm 232 and the second insulating arm 233 are respectively pressed and elastically deformed toward the deformation space 24, and the first conductive portion 212 and the second conductive portion 222 are electrically connected (in this embodiment, the first conductive portion 212 and the second conductive portion 222 abut against each other and are electrically connected; of course, in other embodiments, the first conductive portion 212 and the second conductive portion 222 can be indirectly connected through a third party to achieve electrical connection). In this way, the signal between the first electronic component 2000 and the second electronic component 3000 can be transmitted through the first contact portion 213, the first conductive portion 212, the second conductive portion 222 and the second contact portion 223. The path from the first contact portion 213 through the insulating member 23 to the second contact portion 223 is called the first path, and the path from the first contact portion 213 through the first conductive portion 212 and the second conductive portion 222 to the second contact portion 223 is called the second path. The length of the first path is longer than the length of the second path. The signal between the first electronic component 2000 and the second electronic component 3000 is transmitted through the second path, which shortens the signal transmission path and is beneficial for high frequency.
[0039] like Figures 7 to 10 The diagram shows a second embodiment of the electrical connector 1000, which differs from the terminal module 2 and electrical connector 1000 of the first embodiment in that (the remaining structure and connection relationships are the same as in the first embodiment): the insulating member 23 is a three-piece type. Specifically, the first insulating arm 232 has a separately configured first bridging section 2322' and a first extension section 2321', and the first connecting portion 211 is positioned on the first bridging section 2322'. The second insulating arm 233 has a separately configured second bridging section 2332' and a second extension section 2331', and the second connecting portion 221 is positioned on the second bridging section 2332', and the second extension section 2331' is located below the first extension section 2321'. In this embodiment, the first extension section 2321' and the second extension section 2331' are horizontally arranged, the first bridging section 2322' extends upward relative to the first extension section 2321', and the second bridging section 2332' extends downward relative to the second extension section 2331'. The first insulating arm 232 also has a connecting section 2323 integrally connected to the first extension section 2321' and the second extension section 2331'. The connecting section 2323 is bent and integrally connected to the upper end of the insulating fixing part 231.
[0040] like Figures 7 to 10As shown, the insulating fixing part 231, the connecting section 2323, the first extension section 2321' and the second extension section 2331' are integrally formed and are made of a plastic material with good elasticity, such as silicone rubber or PA material; while the first bridging section 2322' and the second bridging section 2332' are separately set from the above four parts, and the end of the first bridging section 2322' away from the first extension section 2321' covers the first connecting part 211, so that part of the insulating material extends into the first positioning hole 2111, thereby strengthening the holding force between the first bridging section 2322' and the first connecting part 211; the other end of the first bridging section 2322' is also provided with a first buckle part 23221', and the first extension section 2322'... 321' is provided with a first mating groove 23211' corresponding to the first snap-fit portion 23221'. The first snap-fit portion 23221' and the first mating groove 23211' are engaged to fix the first bridging section 2322' and the first extension section 2321'. Moreover, the dielectric constant of the first bridging section 2322' is smaller than that of the first extension section 2321'. For example, a plastic with a dielectric constant (DK) value between 2.7 and 3.0 is used. This makes the dielectric constant of the first bridging section 2322' covering the first connecting portion 211 lower, which in turn makes the dielectric constant around the first connecting portion 211 smaller, causing the resonant frequency point to shift backward, which is beneficial to the high-frequency performance of the electrical connector 1000. The second bridging segment 2332' covers the second connecting portion 221 at one end away from the second extension segment 2331', and the other end is provided with a second snap-fit portion 23321'. The second extension segment 2331' is provided with a second mating groove 23311'. The second snap-fit portion 23321' and the second mating groove 23311' are engaged to fix the second bridging segment 2332' and the second extension segment 2331'. Moreover, the dielectric constant of the second bridging segment 2332' is smaller than that of the second extension segment 2331'. For example, a plastic with a dielectric constant (DK) value between 2.7 and 3.0 is used. This makes the dielectric constant of the second bridging segment 2332' covering the second connecting portion 221 lower, which in turn makes the dielectric constant around the second connecting portion 221 smaller, and the resonant frequency point shifts backward, which is beneficial to the high frequency of the connector.
[0041] In summary, the terminal module 2 and electrical connector 1000 of this utility model have the following beneficial effects:
[0042] (1) The first terminal 21 abuts against the first electronic component 2000 upward through the first contact portion 213, and the second terminal 22 is electrically connected to the second electronic component 3000 downward through the second contact portion 223. The first conductive portion 212 and the second conductive portion 222 are also electrically connected to each other. This allows the signal from the first electronic component 2000 to flow from the first contact portion 213 through the first conductive portion 212 and the second conductive portion 222 to the second contact portion 223, and finally to the second electronic component 3000 through the second contact portion 223. Furthermore, because the path from the first contact portion 213 through the insulating member 23 to the second contact portion 223 is longer than the path from the first contact portion 213 through the first conductive portion 212 and the second conductive portion 222 to the second contact portion 223, the signal transmission path between the first electronic component 2000 and the second electronic component 3000 is shortened, which is beneficial for high frequencies. Moreover, because the insulating member 23 has a first connecting portion 211 bent towards the first terminal 21... The first insulating arm 232 extends and positions the first connecting portion 211, and the second insulating arm 233 extends and positions the second connecting portion 221 towards the second terminal 22. A deformation space 24 exists between the first insulating arm 232 and the second insulating arm 233. This allows the first terminal 21 and the second terminal 22 to be displaced in the vertical direction, thereby ensuring that the first terminal 21 can conduct the first electronic component 2000 well and the second terminal 22 can conduct the second electronic component 3000 well. Moreover, since the insulating member 23 is made of insulating material, when the first electronic component 2000 and the second electronic component 3000 transmit signals through the first terminal 21 and the second terminal 22, the induced magnetic field generated will not cause the plastic insulating member 23 to generate an induced current, avoiding signal crosstalk between the first terminal 21 and the second terminal 22. This allows the signal between the first terminal 21 and the second terminal 22 to be transmitted stably, which is beneficial to the high-frequency performance of the electrical connector 1000.
[0043] (2) The first bridging segment 2322' and the first extension segment 2321' are separately disposed, and the dielectric constant of the first bridging segment 2322' is less than that of the first extension segment 2321'. The second bridging segment 2332' and the second extension segment 2331' are separately disposed, and the dielectric constant of the second bridging segment 2332' is less than that of the second extension segment 2331'. This results in lower dielectric constants for the first bridging segment 2322' covering the first connecting portion 211 and the second bridging segment 2332' covering the second connecting portion 221, thereby reducing the dielectric constant around the first connecting portion 211 and the second connecting portion 221. Furthermore, due to the lower dielectric constant of the first bridging segment 2322', the dielectric constant of the first connecting portion 211 and the second connecting portion 221 is also lower. During signal transmission, the signals flowing into the first connection portion 211 and the second connection portion 221 of the sub-component 2000 and the second electronic component 3000 will produce a stub effect. The stub effect is a type of resonance. According to relevant derivation formulas, the smaller the dielectric constant (DK) of the plastic, the faster the wave velocity and the shorter the electrical length (wavelength), which will increase the resonant frequency. This will reduce the dielectric constant around the first connection portion 211 and the second connection portion 221, thereby increasing the resonant frequency at the first connection portion 211 and the second connection portion 221. As a result, the resonant frequency point will shift backward, which is beneficial to the high frequency of the connector.
[0044] (3) The first insulating arm 232, the second insulating arm 233, and the insulating fixing part 231 are integrally formed and made of elastic plastic, which gives the insulating part 23 good elasticity, thereby providing elasticity for the first terminal 21 and the second terminal 22. The first connecting part 211 has a first positioning hole 2111. The first insulating arm 232 is injection molded so that one end covers the first connecting part 211 and part of the insulating material extends into the first positioning hole 2111. The second connecting part 221 has a second positioning hole 2211. One end of the injection-molded second insulating arm 233 covers the second connecting portion 221, and part of the insulating material extends into the second positioning hole 2211. Thus, the setting of the first positioning hole 2111 and the second positioning hole 2211 can increase the holding force of the first insulating arm 232 and the first connecting portion 211, as well as the holding force of the second insulating elastic arm and the second connecting portion 221, thereby preventing the first insulating arm 232 and the first connecting portion 211 from disengaging, and the second insulating arm 233 and the second connecting portion 221 from disengaging.
[0045] (4) The second contact portion 223 extends upward from the end away from the second connecting portion 221 and towards the side away from the insulating fixing portion 231, with an inclined section 224 and an abutting section 225 extending upward from the upper end of the inclined section 224. The second conductive portion 222 is connected to the upper end of the abutting section 225. When the first electronic component 2000 presses down on the first contact portion 213 and the second electronic component 3000 abuts upward against the second contact portion 223, the second insulating arm 233 will give the second terminal 22 a spring force to deform towards the side away from the insulating fixing portion 231, thereby enabling the abutting section 225 to abut against the side wall of the receiving groove 11, so that the first conductive portion 212 and the second conductive portion 222 can make stable contact.
