[0037] The present invention will be further described below with reference to the drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the specific embodiments cited are not intended to limit the present invention. Embodiment 1
[0038] Referring to Figures 1-8 As shown, a universal connector of the present invention includes:
[0039] A housing, on one side of which an insertion cavity 24 is provided;
[0040] An insulating mechanism, which is arranged on the other side of the housing and includes: an insulating body 10, a guide arm 22 and a receiving space 23. The insulating body 10 is provided with a plurality of guide arms 22, and a receiving space 23 is arranged between adjacent guide arms 22;
[0041] A terminal module, which includes a plurality of connection terminals and a plurality of contact terminals corresponding to and electrically connected to the connection terminals. The connection terminals are arranged in the insertion cavity, the contact terminals are correspondingly received in the receiving space, and the contact terminals include: a first limiting portion 72, an elastic portion 73, and a contact portion 74. The first limiting portion 72 is connected to the connection terminal 71, the elastic portion 73 is connected to the end of the first limiting portion 72, and the contact portion 74 is arranged between the guide arms 22 through the elastic portion 73 in a transitional manner.
[0042] A universal connector according to the present invention, the connection terminals 71 in the terminal module 7 extend into the insertion cavity 24 of the housing, and other connection objects are connected to the connection terminals 71 in the insertion cavity 24. The connection terminals 71 correspond to the number of contact terminals and are electrically connected. The contact terminals are limited by an insulating mechanism. By arranging the guiding arms 22 and the contact terminals alternately, the contact terminals are located in the receiving space 23 formed between adjacent guiding arms 22 and thus are limited. At the same time, the guiding arms 22 space adjacent contact terminals to prevent short circuit. The contact terminals elastically abut against the conductive sheets of the substrate 1. The plane where the substrate 1 is located is a horizontal plane, that is, the plane where the first direction (X-axis direction in the figure) and the second direction (Y-axis direction in the figure) are located. The contact portion 74 of the contact terminal is not parallel to the horizontal plane, that is, the direction where the contact portion of the contact terminal is located has an included angle with the horizontal plane, so that the connector can be connected to the substrates 1 with different heights in the first direction, enabling the connector to adapt to the substrates 1 in different devices, improving the adaptability range of the connector, and making it have universality.
[0043] In order to make the contact force between the contact terminals and the substrates 1 with different heights the same, improve the connection stability and increase the floating stroke, the direction where the contact portion 74 is located is perpendicular to the plane where the substrate 1 is located. The contact portion and the guiding arm are arranged in parallel at intervals, that is, the direction where the contact portion 74 is located is the third direction (Z-axis direction in the figure). The thickness of the PCB substrate is 0.8 mm - 1.2 mm, preferably 1.0 mm. The height of the contact portion is 0.8 - 5.0 mm. The height difference between the contact portion and the thickness of the substrate is 0 mm - 4.0 mm, that is, the vertical floating height range of the connector relative to the substrate 1 is between 0 mm - 4.0 mm. In this embodiment, the midpoint position of the contact portion 74 is used as the default installation position. The height of the contact portion 74 is 4.0 mm, the thickness of the substrate 1 is 1 mm, and the height difference between them is 3.0 mm, so that the floating range of the substrate and the connector in different housings is ±1.5 mm, which can not only adapt to the internal spaces of laptops and automotive center consoles, will not occupy too much height in the housing to be installed, and at the same time can meet the connection with substrates 1 with different heights inside laptops and automotive center consoles.
[0044] Figure 1 It is a three-dimensional view of the connector of this embodiment installed on the base 2 and abutting against the substrate 1 to be contacted, showing the installation state of the connector body and the connection relationship inside the electrical equipment. The illustrations of the two groups of substrates 1 represent the upper limit and lower limit positions of the floating of the substrate 1 relative to the connector. Other connection objects are connected to this connector through the insertion cavity 24.
[0045] See Figure 5As shown, the contact terminal includes: a first limiting portion 72, an elastic portion 73, a contact portion 74, and a second limiting portion 75. The first limiting portion 72 is connected to the connection terminal 71. The first limiting portion 72 is disposed at the top of the insulating body 10 and connected to the connection terminal 71. The elastic portion 73 is connected to the end of the first limiting portion 72. The contact portion 74 is elastically connected to the first limiting portion 72 through the elastic portion 73. The second limiting portion 75 is received in the receiving space 23. The contact portion 74 protrudes from the insulating body 10. The first limiting portion 72 is disposed in the receiving space 23 and does not contact the insulating body 10 in the initial state. The first limiting portion 72 is disposed along the second direction. The end of the first limiting portion 72 is connected to the contact portion 74 through the elastic portion 73. The elastic portion 73 is arc-shaped. Through the transition of the elastic portion 73, the contact portion 74 is disposed along the third direction. The end of the contact is limited by the second limiting portion 75. The two ends of the contact portion 74 are limited by the cooperation of the first limiting portion 72 and the second limiting portion 75.
[0046] See Figure 7 As shown, the receiving space 23 includes: a guiding groove 231, a partition groove 232, and a through hole 233. The guiding groove 231 is opened at the top of the insulating body 10. There is a distance between the first limiting portion 72 and the elastic portion 73 and the guiding groove 231. The partition groove is formed between adjacent guiding arms 22. The width of the partition groove is greater than the width of the contact portion 74. The through hole 233 is opened at the bottom of the insulating body 10. The second limiting portion 75 elastically abuts against the wall of the through hole 233. In the default state, the first limiting portion 72 is located in the cavity of the guiding groove 231 and does not contact the wall of the guiding groove 231. An arc transition is provided between the guiding groove 231 and the partition groove 232. The arc transition is adapted to the shape of the elastic portion 73, and the elastic portion 73 also does not contact the inner wall of the arc transition groove. A flange extends from the bottom of the insulating body 10 toward the guiding arm 22 side. The number of the through holes 233 corresponds to the second limiting portion 75. The through holes 233 penetrate the flange along the third direction. The through holes 233 are disposed in the projection area of the second limiting portion 75 along the third direction. The second limiting portion 75 inclines from the end of the contact portion 74 toward the side close to the insulating body 10. The inclination direction of the second limiting portion 75 is symmetric to the inclination direction of the elastic portion 73, so that the contact portion 74 protrudes on the contact terminal for easy abutment with the substrate 1.
[0047] During the installation of the connector and the substrate 1, the connector is installed from top to bottom onto the base 2, such that the contact portion 74 also slides and abuts against the conductive sheet of the substrate 1 from top to bottom accordingly. By providing the second guiding portion at the bottom of the contact portion 74, a guiding with an inclined angle can be formed between the contact portion 74 and the substrate 1, causing the substrate 1 to press against the second limiting portion 75 along the inclined angle until the connector is installed onto the base 2. At this time, the conductive sheet of the substrate 1 and the contact portion 74 are elastically abutted at corresponding heights.
[0048] Since the contact portion 74 inevitably tilts due to the deformation of the elastic portion 73 during the installation process, in some embodiments, the contact portion 74 tilts from the elastic portion 73 towards the side away from the elastic portion 73, with an inclined angle of 1° - 5°. The inclined angle is positively correlated with the set elastic pre-abutting force and can be set to 3°. When the installation of the contact portion 74 and the substrate 1 is completed, the elastic pre-abutting force at this time exactly causes the contact portion 74 to tilt 3° in the opposite direction along the inclined angle, keeping the contact portion 74 in a vertical state, so that the contact portion 74 fits with the conductive sheet, increasing the contact area and connection stability, and reducing signal loss.
[0049] The inclined angle can also be set to be adjustable, such that the elastic pre-tightening force between the connector and the substrate 1 is adjustable. By adjusting different inclined angles of the contact portion 74, the elastic pre-tightening force can be adjusted. For example, by detachably bonding gaskets with different thicknesses in the through hole, or by screwing through the side wall of the through hole to abut against the second limiting portion.
[0050] See Figure 2 、 Figure 3 、 Figure 8As shown in the figure, the housing includes: a first housing 11 and a second housing 3. The first housing 11 is wrapped around the outer periphery of the insulating mechanism. The second housing 3 is wrapped on one side of the first housing 11 and is connected to the base 2 to be installed on the other side of the first housing 11. The base 2 to be installed is provided with a third groove for accommodating the first housing 11. A double-layer housing structure is formed by the first housing 11 and the second housing 3. The inner first housing 11 is used to be connected to the limit. The insertion cavity 24 is arranged in the first housing 11. The first housing 11 is embedded in the base 2. The second housing 3 and the base 2 enclose the outer periphery of the first housing 11, and the second housing 3 is connected to the base 2. The limit seat is provided with a positioning rod 14 extending towards the first housing 11 in the third direction. The positioning rod 14 is adapted to the recess on the outer side of the first housing 11. The recess of the first housing 11 is the notch on both sides of the existing HDMI interface. The positioning rod 14 is arranged between the first housing 11 and the second housing 3 and is clamped in the notch. The first housing 11 is limited by locking the second housing 3 in the third groove of the base 2 to be installed. Further, the first housing 11 is limited in the first direction by the positioning rod 14, effectively preventing the side of the first housing 11 and the limit seat close to the substrate 1 from slipping or deforming in the first direction.
[0051] See Figure 2 , Figure 4 As shown in the figure, the limit seat is provided with a first positioning portion 19. The second housing 3 is provided with a first positioning hole that cooperates with the first positioning portion 19. The base 2 to be installed is provided with a second positioning portion 5. The second housing 3 is provided with a second positioning hole that cooperates with the second positioning portion 5. The second positioning hole is arranged in the first direction of the second housing 3. By the cooperation of the first positioning portion 19 and the first positioning hole, the positioning accuracy of the limit seat and the second housing 3 and the connection strength against lateral force are improved. By the cooperation of the provided second positioning portion 5 and the second positioning hole, the second housing 3 is positioned on the base 2. And the second positioning hole and the second positioning portion 5 are on both sides of the second housing 3 along the first direction, which can prevent the second housing 3 from expanding outwards in the first direction, resulting in the offset of the limit seat clamped thereto. Part of the connection terminal 71 is embedded into the interior of the limit seat, and one end of the connection terminal 71 is connected to the contact terminal, and the other end enters the insertion cavity 24 and is connected to the electrical object. The number of terminals is 19 groups, and the ground terminals and the signal terminals are arranged at intervals.
[0052] See Figures 2-4 As shown in the figure, the universal connector further includes a limiting mechanism. The limiting mechanism is arranged in the housing. The terminal module 7 is arranged in the limiting mechanism.
[0053] The limiting mechanism includes: a limiting seat, retaining walls 8, a convex body 20, a third limiting portion 6, a first groove 25, a second groove 26, and a positioning groove 21. The limiting seat extends to one side with at least two groups of retaining walls 8. The insulating body 10 is arranged between at least two groups of retaining walls 8. A convex body 20 is arranged on one side of at least two groups of retaining walls 8 close to the insulating body 10. The insulating body 10 is provided with a positioning groove 21 that matches the convex body 20. On both sides of the other side of the limiting seat, a first groove 25 and a second groove 26 are respectively opened. The first groove 25 matches the first end portion 12 of the first housing 11, and the second groove 26 matches the second end portion 13 of the second housing 3. The limiting seat extends to the other side with at least two groups of third limiting portions 6. One side of the first housing 11 is arranged between at least two groups of third limiting portions 6. The limiting seat limits the insulating body 10 in the first direction through the retaining walls 8. The convex body 20 on the retaining wall 8 is inserted into the positioning groove 21 of the insulating body 10 to position and limit the insulating body 10 in the second direction. The third limiting portion 6 is respectively formed with a first step surface 17 and a second step surface 18 on the upper and lower sides. The limiting seat is provided with a third step surface that matches the first step surface 17, so that the limiting seat is lapped on the third limiting portion 6. The bottom of the first housing 11 extends into the second step surface 18, so that the outer shell and the limiting seat limit the insulating body 10 in the third direction, thereby limiting and positioning the insulating body 10 in three directions.
[0054] The to-be-installed substrate 1 is provided with a fourth groove 15. Two groups of retaining walls 8 are respectively arranged on both sides of the fourth groove 15 along the first direction. Since the connector and the substrate 1 can relatively slide in the height direction, i.e., the third direction, and the substrate 1 and the connector are in an abutting relationship in the second direction, during the assembly process of the connector and the substrate 1, it is necessary to ensure the positioning in the first direction. By respectively abutting the retaining walls 8 on both sides in the first direction against the two side walls of the fourth groove 15, the fourth groove 15 and the two groups of retaining walls 8 are symmetric and have a matching shape. During the sliding insertion assembly process, the fourth groove 15 guides and limits the retaining walls 8 on both sides of the insulating body 10 in the first direction, which can improve the assembly accuracy and speed, and at the same time can protect the terminals from being crushed during the assembly. The assembly allowance between the fourth groove 15 and the retaining walls 8 is 0.1 mm, so that the assembly accuracy of the connector and the substrate 1 is greater than the width of the connection part between the contact part 74 and the conductive sheet, and at the same time is greater than the adjacent terminal pitch and the adjacent conductive sheet pitch, which can meet the requirements of connection accuracy.
[0055] On one side of the guiding arm 22 close to the elastic part 73, a taper part is provided. The elastic part 73 protrudes from the taper part in the first direction. On at least one side of the taper part along the third direction, a first taper surface 221 is provided. On at least one side of the taper part along the first direction, a second taper surface 223 is provided. The included angle between the second taper surface 223 and the second direction is an acute angle. The included angle between the first taper surface 221 and the third direction is less than 60°. During the installation of the connector, the first taper surface 221 of the taper part, especially the first taper surface 221 on the side, can play a protective role. The top surface 222 of the taper part is a plane. During installation, in order to maintain elastic abutting contact, the part usually approaches the insulating body 10. At the bottom of the guiding arm 22, since it is close to the substrate 1 and the initial abutting part of the contact part, it is not convenient to set a taper part to hinder the abutting of the substrate 1 and the contact part 74, and the bottom of the contact is a free end, which can allow a relatively large deformation angle within the elastic range. However, when reaching the middle of the contact part, if the installation force is large in the second direction, it will cause the elastic part 73 to deform excessively, exceeding the elastic deformation range and becoming plastic deformation, resulting in damage to the elasticity of the contact part 74 and it cannot be restored. Therefore, the taper part is set. If the installation force is too large, it will abut against the taper part and be blocked, and the contact part 74 is protected by the taper part. Further, the guiding arm 22 itself can also elastically deform along the first direction through the hollow window, and the elastic modulus of the guiding arm 22 is greater than that of the elastic part 73. The guiding arm 22 is a frame structure protruding from the insulating body 10. A window is formed by enclosing the guiding arm 22 and the insulating body 10. The materials of the insulating body 10, the taper part and the guiding arm 22 are selected from one or more of rubber, plastic, and silica gel. In this embodiment, the materials of the insulating body 10, the taper part and the guiding arm 22 are all plastic, and their elasticity is moderate and the insulation performance is good.
[0056] On the top of the insulating body 10, a plurality of extensions 16 corresponding to the contact terminals are provided. The extensions 16 extend from the insulating body 10 to the side close to the contact part. The height of the insulating body 10 is greater than that of the first limiting part 72. A mylar sheet 9 is provided between the insulating body 10 and the first housing 11. The mylar sheet 9 is specifically provided between the extension and the first housing 11. Through the extended extension 16, the elastic part 73 can be protected to prevent plastic deformation caused by accidental collision with the elastic part 73 during installation. By setting the mylar sheet 9, an insulating protection is formed between the first limiting part 72 and the second housing, and at the same time, a protective cushion layer is formed between the extension 16 and the second housing 3. The second housing 3 extends along the first direction to cover the extension 16 and does not directly contact the extension 16, further protecting the extension 16 and improving the integrity at the same time. The second housing 3 is also provided with a locking hole 4, and the base 2 is detachably connected to the locking hole 4 by bolts.
[0057] The substrate 1 to be installed is provided with a conductive sheet on one side close to the contact portion 74. At the same time, the conductive sheet extends toward the second direction on both surfaces of the substrate 1 along the third direction. The conductive sheet corresponds to the contact portion 74. The width of the contact portion 74 is 0.3 mm - 0.4 mm. In order to ensure the reliability of the connection between the contact portion 74 and the conductive sheet, the width of the conductive sheet is 0.6 mm - 0.8 mm. In this embodiment, the width of the contact portion 74 is 0.35 mm, and the width of the conductive sheet is 0.7 mm. Even if the conductive sheet has a slight displacement in the first direction, the contact portion 74 is completely on the conductive sheet. The distance between adjacent conductive sheets is 0.1 - 0.3 mm, and preferably 0.2 mm in this embodiment. Due to the small distance between adjacent conductive sheets, through the second taper surface 223 of the taper portion, the respective contact terminals are guided and positioned in the second direction. During the abutting process of the substrate 1, each contact terminal can accurately abut against the corresponding conductive sheet.
[0058] In this embodiment, the distance between adjacent contact terminals is 0.75 mm, which is compact in structure and avoids interfering with each other's signals at the same time.
[0059] Figure 9 It is a parameter curve graph of the IMPZ (characteristic impedance) of a universal connector in an embodiment of the present invention. As Figure 9 shown, the abscissa is the time of the differential pair, with the unit of ns, and the ordinate represents the resistance of the differential pair, with the unit of Ω. The four curves represent four groups of differential pairs. The two horizontal lines at the ordinate values of 90 and 110 are the standard upper and lower limits. Although the lower limit of TDRZt (Dff8) Setup22:Sweep1 in the differential pair curve is lower than 90, when observing this section of M1 and M2, the time coordinates of M1 and M2 are 160 ps and 226 ps respectively. The instantaneous impedance within this time period is still greater than 85 dB, and its impedance between M1 and M2 is greater than 85 dB, meeting the standard. Similarly, the effects of the other differential pairs are better than this curve, so all meet the standard.
[0060] Figure 10 It is a parameter curve graph of the IL (insertion loss) of a universal connector in an embodiment of the present invention. As Figure 10 shown, the abscissa difference is the frequency of the differential pair, with the unit of GHz, and the ordinate represents the ratio of the output power to the input power of the differential pair, with the unit of dB. The four curves represent the insertion losses of four groups of differential pairs at different frequencies. The effective frequency range is 0 GHz - 12 GHz. The oblique line Y is the qualified standard. The four groups of differential pairs in this embodiment select 2.5 GHz as the measurement point, and their insertion loss is less than 0.5481 dB, achieving the effects of small insertion loss and good performance indicators.
[0061] Figure 11This is the parameter curve graph of the IMPZ (characteristic impedance) of a general-purpose connector in an embodiment of the present invention. As Figure 11 shown, the abscissa difference is the frequency of the differential pair, with the unit of GHz, and the ordinate represents the signal-to-noise ratio of the differential pair, with the unit of dB. The two curves represent the signal-to-noise ratios of two groups of differential pairs at different frequencies. The effective frequency range is 0 GHz - 12 GHz. The multi-segment straight line Y is the qualified standard. The signal-to-noise ratios of the two curves within the effective frequency range all meet the requirements, and the signal-to-noise ratio can still reach 50 dB at 10 GHz. Its signal-to-noise ratio is high, and the influence of noise is smaller, so the anti-interference ability is strong. Embodiment 2
