Description

Technical Field

[0001] The present invention relates to the field of electrical connectors, and particularly to a high-speed connector. Background Art

[0002] Existing high-speed connector assemblies generally include a male connector and a female connector that docks with the male connector. Since the female connector usually uses elastic terminals for elastic electrical contact with the male connector, while the male end usually requires a straight terminal structure that is non-elastic or has weaker elasticity than the elastic terminals of the female end. Moreover, as the requirements for high-speed signal transmission gradually increase, the standard for the docking stability between the male connector and the female connector of the existing high-speed connector assembly has also increased. The existing male connector is prone to problems such as unstable fixing of the male terminals and poor centering accuracy. Therefore, when the male and female connectors are docked, the male terminals are prone to displacement and damage, or the terminals of the male and female ends do not contact properly, affecting the transmission of high-speed signals. Therefore, the firm reliability and centering accuracy of the terminals of the existing male connector need to be further improved. Summary of the Invention

[0003] In view of this, it is necessary to provide a high-speed connector that has the advantage of good holding stability of the conductive terminals to meet the centering accuracy requirements.

[0004] To solve the above technical problems, the present application provides a high-speed connector, including an insulating body and a plurality of conductive terminals held by the insulating body. The insulating body includes a base, and the base includes a plurality of installation grooves for the plurality of conductive terminals to be correspondingly inserted and fixed. The plurality of conductive terminals each include a contact portion for docking with the terminals of a docking connector, a fixing leg, and a holding portion connecting the contact portion and the fixing leg. The holding portion is held in the base by an interference fit. The holding portion includes at least one protruding portion, and when observed in the lateral direction, the protruding portion protrudes from the front surface or the rear surface of the holding portion.

[0005] Further, when observed in the lateral direction, the protruding portions of the plurality of conductive terminals of the high-speed connector of the present invention all protrude from the front surface or the rear surface of the holding portion in the same direction.

[0006] Further, the protruding portion of the high-speed connector of the present invention includes a clamping portion protruding from the surface of the holding portion and an inclined surface continuously extending from the surface of the holding portion to the clamping portion. The clamping portion is embedded and clamped on the inner wall surface of the installation groove in a direction opposite to the insertion and installation direction of the conductive terminal.

[0007] Furthermore, each of the plurality of conductive terminals of the high-speed connector of the present invention includes at least two protruding portions arranged vertically, and the clamping portions of the at least two protruding portions of each conductive terminal are respectively arranged in at least two horizontal regions perpendicular to the vertical direction.

[0008] Furthermore, the plurality of conductive terminals of the high-speed connector of the present invention include signal terminals and ground terminals. The inclined surface of the signal terminal is located below the clamping portion and continuously extends upward from the surface of the holding portion to the clamping portion. The inclined surface of the ground terminal is located above the clamping portion and continuously extends downward from the surface of the holding portion to the clamping portion.

[0009] Furthermore, the base of the high-speed connector of the present invention has an upper surface and a lower surface corresponding to the upper surface. The plurality of mounting grooves penetrate the base vertically. The plurality of mounting grooves include a plurality of first mounting grooves and a plurality of second mounting grooves for respectively receiving and fixing the signal terminals and the ground terminals. The first mounting groove includes a first step portion near the upper surface and a first mounting and fixing groove penetrating the base downward from the first step portion. The second mounting groove includes a second step portion near the lower surface and a second mounting and fixing groove penetrating the base upward from the second step portion. The holding portion further includes a stop portion protruding laterally from both sides of the holding portion. The stop portion of the signal terminal is located near the contact portion of the signal terminal, and the stop portion of the ground terminal is located near the fixing leg of the ground terminal. The signal terminal is inserted into the first mounting groove from top to bottom, and the stop portion of the signal terminal abuts downward against the first step portion. The ground terminal is inserted into the second mounting groove from bottom to top, and the stop portion of the ground terminal abuts upward against the second step portion.

[0010] Furthermore, the first mounting groove of the high-speed connector of the present invention further includes a first opening recessed from the upper surface. Two laterally adjacent first mounting and fixing grooves are connected in one first opening, and the stop portions of two laterally adjacent signal terminals corresponding to one first opening are received in the first opening. The second mounting groove further includes a second opening recessed from the lower surface, and the stop portion of the ground terminal is received in the second opening.

[0011] Furthermore, the vertical distance from the second step portion to the lower surface is greater than the vertical distance from the first step portion to the upper surface.

[0012] Furthermore, when the high-speed connector of the present invention is observed in the up and down direction, the laterally adjacent first opening and second opening partially overlap.

[0013] Furthermore, the holding part of the high-speed connector of the present invention further includes side convex parts protruding from both lateral sides. The plurality of conductive terminals include signal terminals and ground terminals, and the side convex parts of the signal terminals and the side convex parts of the ground terminals are arranged in a staggered manner in the up-down direction.

[0014] Compared with the prior art, the present invention has the following advantages: Since in the front-back direction, the holding part of the conductive terminal is provided with a protruding convex part, the conductive terminal can be positioned in the front-back direction; and because the side convex parts of adjacent signal terminals and ground terminals are arranged in a staggered manner in the up-down direction, better support and fixation of each terminal can also be achieved in the lateral direction; and because the clamping parts of each terminal are arranged in the same horizontal plane, it is beneficial to the stable holding between each terminal and the insulating body, and also ensures the orthogonality of the terminals.

[0036] The plurality of conductive terminals 2 include a plurality of signal terminals S and a plurality of ground terminals G. The plurality of signal terminals S and the plurality of ground terminals G are arranged in multiple rows L in a specific order and correspond to the plurality of mounting grooves. Among the plurality of conductive terminals 2 in a horizontal row L, the signal terminals S are provided in a pair, and a ground terminal G is arranged at an interval on one lateral side of the pair of signal terminals S. When there are multiple pairs of signal terminals S among the plurality of conductive terminals 2 in a horizontal row L, a ground terminal G is arranged at an interval between the two pairs of signal terminals S. In some embodiments, among the multiple rows L of conductive terminals 2 arranged side by side in the front-rear direction, signal terminals S are arranged at intervals between two adjacent ground terminals G in the front-rear direction. The conductive terminals 2 at the outermost lateral sides in a horizontal row L of the plurality of conductive terminals 2 are both ground terminals G, and no signal terminal S is arranged between the ground terminals G at the outermost lateral sides of each row L and the adjacent ground terminals G in the front-rear direction.

[0037] Please refer to Figure 9 As shown, the bottom ends of the fixing legs 23S of the signal terminals S are flush with the bottom ends of the fixing legs 23G of the ground terminals G. The overall height HS of the signal terminals S in the up-down direction is less than or equal to the overall height HG of the ground terminals G.

[0038] Please refer to Figure 8 、 Figure 9 、 Figure 11 and Figure 12 As shown, the ground terminal G includes a contact portion 21G, a holding portion 22G, and a fixing leg 23G. The holding portion 22G of the ground terminal G includes a convex portion 222G protruding in a tearing manner in the front-rear direction. The convex portion 222G includes a clamping portion 223G at the lower end and an inclined surface 224G extending from the upper end of the convex portion 222G to the clamping portion 223G. The clamping portion 223G protrudes in the front-rear direction from the corresponding surface of the holding portion 22G of the ground terminal G. The inclined surface 224G of the ground terminal G gradually protrudes from the corresponding surface of the holding portion 22G of the ground terminal G from top to bottom. The inclined surface 224G continuously extends to the clamping portion 223G to provide support for the clamping portion 223G. The clamping portion 223G is a tearing opening, which can facilitate the clamping portion 223G to be embedded and clamped on the inner wall surface of the mounting and fixing groove. The holding portion 22G of the ground terminal G further includes a stop portion 225G near the fixing leg 23G of the ground terminal G. The stop portion 225G protrudes laterally from both lateral sides of the holding portion 22G, and the overall lateral length of the stop portion 225G is greater than the overall lateral length of the corresponding mounting and fixing groove. In some embodiments, the convex portions 222G are at least two arranged vertically and all protrude from the corresponding surface of the holding portion 22G in the same front-rear direction.

[0039] Please refer to Figure 8 , Figure 9 , Figure 11 and Figure 12 As shown, the signal terminal S includes a contact portion 21S, a holding portion 22S, and a fixing pin 23S. The holding portion 22S of the signal terminal S includes a convex portion 222S formed by tearing and protruding in the front-rear direction. The convex portion 222S includes a clamping portion 223S located at the upper end and an inclined surface 224S extending from the lower end of the convex portion 222S to the clamping portion 223S. The clamping portion 223S protrudes in the front-rear direction from the corresponding surface of the holding portion 22S of the signal terminal S. The inclined surface 224S continuously extends to the clamping portion 223S to provide support for the clamping portion 223S. The clamping portion 223S is a tear opening, which can facilitate the clamping of the clamping portion 223S into the inner wall surface of the mounting and fixing groove. The inclined surface 224S of the signal terminal S gradually protrudes from the corresponding surface of the holding portion 22S of the signal terminal S from bottom to top. The holding portion 22S of the signal terminal also includes a stop portion 225S located near the contact portion 21S of the signal terminal S. The stop portion 225S protrudes laterally from both lateral sides of the holding portion 22S, and the overall lateral length of the stop portion 225S is greater than the overall lateral length of the 211S. In some embodiments, the convex portions 222S are at least two arranged vertically, and all protrude from the corresponding surface of the holding portion 22G in the same front-rear direction.

[0040] Please refer to Figure 8 , Figure 9 and Figure 12 As shown, when observed in the up-down direction, the overall front-rear thickness of the ground terminal G is greater than the overall front-rear thickness of the signal terminal S. The front-rear thickness of the contact portion 21G of the ground terminal G is greater than the front-rear thickness of the contact portion 21S of the signal terminal S. The lateral length of the contact portion 21G of the ground terminal G is greater than the lateral length of the contact portion 21S of the signal terminal S. The lateral length between the outer sides of the clamping portions 223G on both sides of the ground terminal G is greater than the lateral length between the outer sides of the clamping portions 223S on both sides of the signal terminal S.

[0041] Please refer to Figures 1 to 6 , and Figures 10 to 12 As shown, the plurality of mounting grooves include a plurality of first mounting grooves 12 and a plurality of second mounting grooves 13 for respectively receiving and fixing the signal terminal S and the ground terminal G. The first mounting grooves 12 and the second mounting grooves 13 are arranged at intervals in the transverse direction.

[0042] Please refer to Figure 10As shown, when observed from the front to the back, the first mounting groove 12 has a groove structure that is "wide at the top and narrow at the bottom" in the direction from top to bottom. The first mounting groove 12 includes a first opening 121 recessed downward from the upper surface 11a, a first step portion 122 formed within the first opening 121, and two first mounting and fixing grooves 123 that continue to penetrate downward through the base 11 from the lower end of the first opening 121. The first mounting and fixing grooves 123 are adapted to receive and fix the holding portion 22S of the signal terminal S. In a plane perpendicular to the up-and-down direction, the cross-sectional area of the first opening 121 is greater than the cross-sectional area of the first mounting and fixing grooves 123, and is also greater than the sum of the cross-sectional areas of the two first mounting and fixing grooves 123. The first step portion 122 is located at the connection between the two first mounting and fixing grooves 123 and the first opening 121.

[0043] Please refer to Figure 10 As shown, when observed from the front to the back, the second mounting groove 13 has a groove structure that is "narrow at the top and wide at the bottom" in the direction from bottom to top. The second mounting groove 13 includes a second opening 131 recessed upward from the lower surface 11b, a second step portion 132 formed within the second opening 131, and a second mounting and fixing groove 133 that continues to penetrate upward through the base 11 from the upper end of the second opening 131. The second mounting and fixing groove 133 is adapted to receive and fix the holding portion 22G of the ground terminal. In a plane perpendicular to the up-and-down direction, the cross-sectional area of the second opening 131 is greater than the cross-sectional area of the second mounting and fixing groove 133. The second step portion 132 is located at the connection between the second mounting and fixing groove 133 and the second opening 131. The vertical distance from the second step portion 132 to the lower surface 11b is greater than the vertical distance from the first step portion 122 to the upper surface 11a.

[0044] When observed in the up-and-down direction, among the first mounting groove 12 and the second mounting groove 13 in the same row, the front-to-back distance between the front and back surfaces of the inner side of the first opening 121 is less than the front-to-back distance between the front and back surfaces of the inner side of the second opening 131, the lateral distance between the left and right surfaces of the inner side of the first opening 121 is greater than the lateral distance between the left and right surfaces of the inner side of the second opening 131, and the first opening 121 and the second opening 131 partially overlap in the lateral direction at portion K.

[0045] Please refer to Figure 9 and Figure 11As shown, the side convex portion 221S of the signal terminal S and the side convex portion 221G of the ground terminal G are vertically offset in the up and down direction. In addition, the portion of the holding portion 22G of the ground terminal G corresponding horizontally to the side convex portion 221S of the signal terminal S becomes narrower horizontally. In this way, not only can the signal at this location be improved, but also the lateral extrusion between adjacent signal terminals S and ground terminals G in the same row through the base 11 can be avoided in the horizontal direction, thereby preventing the lateral offset of each terminal to meet the requirement of terminal ortho-position. In addition, it should be pointed out here that the first installation and fixing groove 123 and the second installation and fixing groove 133 corresponding to the horizontally adjacent signal terminal S and ground terminal G together form a wall abutting area. In this abutting area, a horizontal area where the side convex portion 221S of the signal terminal S is located is defined. The side wall of the holding portion 22G of the ground terminal G horizontally adjacent to the signal terminal S is attached to or has a gap with the inner wall surface of the second installation and fixing groove 133. In this way, a lateral deformation space facing the adjacent ground terminal G can be provided for the wall (the inner wall surface of the second installation and fixing groove 123 close to the adjacent ground terminal G) against which the side convex portion 221S of the signal terminal S abuts; by the same principle, another horizontal area where the side convex portion 221G of the ground terminal G is located is defined in this abutting area. The side wall of the holding portion 22S of the signal terminal S horizontally adjacent to the ground terminal G is attached to or has a gap with the inner wall surface of the first installation and fixing groove 123. In this way, a lateral deformation space facing the adjacent signal terminal S can be provided for the wall (the inner wall surface of the first installation and fixing groove 133 close to the adjacent signal terminal S) against which the side convex portion 221G of the ground terminal G abuts. To sum up, the base 11 forms a certain deformation V in this abutting area so that the side convex portions of each terminal can be more smoothly embedded and abutted against the inner wall surface of the installation and fixing groove, avoiding the lateral swing of the terminal and affecting the ortho-position.

[0046] During the assembly of the high-speed connector, the signal terminal S is installed on the base 11 from top to bottom, and the ground terminal G is installed on the base 11 from bottom to top. The fixing feet 23S and the holding parts 22S of the signal terminal S sequentially pass through the first opening 121 and the first installation and fixing groove 123 from top to bottom. The fixing feet 23S are exposed downward below the base 11, the contact part 21S is exposed above the base 11, and the side convex parts 211S and the protruding parts 222S of the holding part 22S are in interference fit with the transverse inner wall surface and the front and rear inner wall surfaces of the first installation and fixing groove 123 respectively to fix the signal terminal S. The inclined surface 224S of the protruding part 222S can facilitate the insertion of the signal terminal S. The clamping part 223S of the protruding part 222S is embedded and clamped on the inner wall surface of the first installation and fixing groove 123 in the direction opposite to the installation direction, which can effectively prevent the signal terminal S from detaching upward from the base 11 during use and also support the coaxiality of the signal terminal S in the front and rear directions. The stop part 225S of the signal terminal S abuts downward against the first step part 122 to prevent the signal terminal S from moving downward excessively. The stop parts 225S of the two signal terminals S are jointly located in a corresponding first opening 121.

[0047] In addition, the contact part 21G and the holding part 22G of the ground terminal G sequentially pass through the second opening 131 and the second installation and fixing groove 133 from bottom to top. The contact part 21G is exposed upward above the base 11, the fixing feet 23G are exposed below the base 11, and the side convex parts 211G and the protruding parts 222G of the holding part 22G are in interference fit with the transverse inner wall surface and the front and rear inner wall surfaces of the second installation and fixing groove 133 respectively to fix the ground terminal G. The inclined surface 224G of the protruding part 222G can facilitate the insertion of the ground terminal G. The clamping part 223G of the protruding part 222G is embedded and clamped on the inner wall surface of the second installation and fixing groove 133 in the direction opposite to the installation direction, which can effectively prevent the ground terminal G from detaching upward from the base 11 during use and also support the coaxiality of the ground terminal G in the front and rear directions. The stop part 225G of the ground terminal G abuts upward against the second step part 132 to prevent the ground terminal G from moving upward excessively. The stop part 225G is located in the corresponding second opening 131.

[0048] During the assembly process of the high-speed connector 100, first, all the signal terminals S are inserted into the base 11, and then the ground terminal G is inserted into the base 11. Since the overall thickness of the signal terminal S in the front-back direction is smaller than that of the ground terminal G, after the signal terminal S is inserted into the base 11, the deformation amount in the lateral plane area of the raised portion 222S of the signal terminal S in the base 11 is smaller than that in the corresponding area after the ground terminal G is inserted into the base 11. Therefore, inserting the signal terminal S first is beneficial to the subsequent smooth insertion of the ground terminal G. When the ground terminal G is finally inserted and positioned, the part between the raised portion 222S of the signal terminal S and the raised portion 222G of the ground terminal G in the base 11 is squeezed, making them clamped more tightly with each other.

[0049] Please refer to Figure 9 , Figure 11 and Figure 12 As shown, in the assembled high-speed connector 100, the clamping portions 223S of the signal terminals S and the clamping portions 223G of the ground terminals G are nearly at the same height M1 in the up-down direction, so that all the signal terminals S and the ground terminals G jointly squeeze the mounting fixing groove within the same horizontal interval to achieve a better fixing effect. When each terminal has multiple clamping portions, the clamping portions of the terminals corresponding to the same horizontal interval are nearly at the same height in the up-down direction. For example, when each terminal has two clamping portions, the clamping portions of each terminal are located at two parallel heights M1 and M2 in the up-down direction to achieve a better fixing effect compared with the setting of a single clamping portion. Moreover, since tear openings are formed at the clamping portions of the signal terminals S and the ground terminals G, this structure can be well embedded into the inner wall surface of the mounting fixing groove in the direction opposite to the mounting direction, ensuring the stability of the clamping.

[0050] Please refer to Figures 6 to 12 As shown, in the high-speed connector 100 of the present invention, the raised portions 222S of the signal terminals S and the raised portions 222G of the ground terminals G are rectangular in shape when observed from the front to the back. In some other embodiments, please refer to Figure 13As shown, the protruding portions 222S' of the signal terminal S' and the protruding portions 222G' of the ground terminal G' are trapezoidal in shape when observed from front to back. Since the installation directions of the signal terminal S' and the ground terminal G' relative to the base are different, the protruding portions 222S' of the signal terminal S' are in an inverted trapezoidal structure with a narrower bottom and a wider top, and the protruding portions 222G' of the ground terminal G' are in a regular trapezoidal structure with a narrower top and a wider bottom. The clamping portions 223S' of the signal terminal S' and the clamping portions 223G' of the ground terminal G' are the wider sides of the trapezoidal structure to ensure stable fixation with the base. Furthermore, the trapezoidally arranged protruding portions make the inclined surfaces 224S' of the signal terminal S' and the inclined surfaces 224G' of the ground terminal G' gradually widen along the installation direction, which is beneficial to the installation and insertion of the terminals and increases the fixation strength between the protruding portions and the base.

[0051] In summary, the high-speed connector of the present invention can effectively solve the problems of stable fixation and co-alignment of each conductive terminal 2 in the insulating body 1, ensuring smooth docking and docking reliability with the docking connector.

[0052] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0053] The above embodiments only represent the preferred embodiments of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
