A high-speed data connector

Abstract

The present invention relates to a high-speed data connector, which includes a PCB board, insulating columns, a metal conductive male socket, an insulating plastic female socket, and wires. The metal conductive male socket includes a conductive shell body and insertion columns. The insertion columns extend further to the right from the right side wall of the conductive shell body, and a receiving cavity is provided therein. The metal conductive male socket is inserted and docked with the insulating plastic female socket along the left-right direction by means of the insertion columns. An anti-fooling column is provided on the right end face of the insulating column. An assembly stop boss is provided on the inner side wall of the receiving cavity. Correspondingly, a top-leaning step is provided on the outer side wall of the insulating column. In this way, on the one hand, after the insulating column is inserted into place relative to the receiving cavity along the direction from right to left, the top-leaning step is in abutting cooperation with the assembly stop boss, thereby ensuring that the insulating column occupies the correct assembly position; on the other hand, the non-anti-fooling end of the insulating column can be inserted into the metal conductive male socket, effectively preventing the anti-fooling column from being worn.

Description

Technical Field

[0001] The present invention relates to the technical field of audio / video device data connection, and particularly to a high-speed data connector. Background Art

[0002] The HSD connector is a High-Speed Data connector, that is, a high-speed transmission connector. Based on the four-core principle, it performs symmetric and impedance-controlled transmission of 100 ohms, and is widely used in handheld products such as mobile phones, digital cameras, MP3 players, and personal digital assistants (PDAs), as well as the automotive manufacturing field. The HSD connector is one of the most important auxiliary connectors in automotive video, which is related to the integrity and efficiency of the video.

[0003] In the prior art, the insulating post lacks a positioning reference relative to the metal conductive male seat, which is not convenient for determining the insertion depth value of the insulating post relative to the metal conductive male seat. In addition, the insulating posts are all inserted from the tail of the metal conductive male seat (that is, Figure 1 in the direction from left to right as shown in the figure). In this way, when there is a little positioning error of the insulating post relative to the metal conductive male seat, the anti-fooling post provided on its right end face may be scratched and damaged, or even broken by the metal conductive male seat, thus affecting the smooth execution of the subsequent Pin pairing process. Therefore, it is urgent for technicians to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a high-speed data connector with a simple structure design, which can avoid damage to the anti-fooling post and ensure that the insulating post has the correct insertion depth value relative to the metal conductive male seat.

[0005] To solve the above technical problems, the present invention relates to a high-speed data connector, including a PCB board, an insulating post, a metal conductive male seat, an insulating plastic female seat, and a wire. The wire is electrically connected to the PCB board and passes through the insulating post. The metal conductive male seat includes a conductive shell body and a plugging column. The plugging column extends further to the right from the right side wall of the conductive shell body, and a receiving cavity is provided therein for placing the above-mentioned insulating post. The metal conductive male seat is inserted and docked with the insulating plastic female seat along the left-right direction through the plugging column. An anti-fooling post is provided on the right end face of the insulating post. An assembly stop boss is provided on the inner side wall of the receiving cavity. Correspondingly, a top-relying step is provided on the outer side wall of the insulating post. When the insulating post is inserted into the receiving cavity in place along the direction from right to left, the top-relying step abuts and cooperates with the assembly stop boss.

[0006] As a further improvement of the technical solution of the present invention, a plurality of limiting protrusions are evenly distributed on the right side of the assembly stop boss around the inner side wall periphery of the receiving cavity.

[0007] As a further improvement of the technical solution of the present invention, a flattened anti-rotation surface is provided along the peripheral side wall of the above-mentioned insulating column in the length direction thereof, and is exactly corresponding to the assembly stop boss.

[0008] As a further improvement of the technical solution of the present invention, a chamfer or fillet is provided around the outer edge of the left end face of the insulating column.

[0009] As a further improvement of the technical solution of the present invention, at least one anti-disengagement annular protrusion is provided around the peripheral edge of the plug post.

[0010] As a further improvement of the technical solution of the present invention, a limiting post extends downward continuously along the bottom wall of the conductive shell body. Correspondingly, a limiting hole adapted to the above-mentioned limiting post is provided on the PCB board.

[0011] Compared with the high-speed data connector of the traditional design structure, in the technical solution disclosed in the present invention, by means of the mutual cooperation relationship between the abutting step and the assembly stop boss, the correct assembly position of the insulating column in the metal conductive male seat is effectively ensured, thereby improving the assembly accuracy; in addition, the insulating column is inserted into the metal conductive male seat from its non-anti-fooling post end, thus preventing the occurrence of wear or breakage of the anti-fooling post.

Specific embodiments

[0024] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "left", "right", "upper", "lower", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0025] The following combines specific embodiments to further elaborate on the content of the present invention. Figure 2 、 Figure 3 、 Figure 4 Respectively show the assembly drawing, top view and A-A cross-sectional view of the high-speed data connector in the present invention. It can be seen that it mainly consists of several parts such as a PCB board 1, an insulating post 2, a male metal conductive seat 3, an insulating plastic female seat 4 and a wire 5. Among them, the wire 5 is electrically connected to the PCB board 1 and passes through the insulating post 2. The male metal conductive seat 3 includes a conductive shell body 31 and a plugging post 32. The plugging post 32 extends further to the right from the right side wall of the conductive shell body 31, and an accommodating cavity 321 is provided therein to be used for placing and adapting to the above-mentioned insulating post 2. The male metal conductive seat 3 is inserted and docked with the insulating plastic female seat 4 along the left-right direction by means of the plugging post 32. An anti-fooling post 21 is provided on the right end face of the insulating post 2 (as shown in Figure 7 ). An assembly stop boss 3211 is provided on the inner side wall of the accommodating cavity 321. Correspondingly, an abutting step 22 is provided on the outer side wall of the insulating post 2 (as shown in Figure 7As shown in the figure. After the insulating column 2 is inserted into place relative to the receiving cavity 321 in the right-to-left direction, the abutting step 22 abuts against the assembly stop boss 3211. In this way, it effectively ensures that the insulating column 2 occupies the correct assembly position in the metal conductive male socket 3, thereby improving the assembly accuracy.

[0026] In addition, it should be noted here that in the above embodiment, the insulating column 2 is inserted into the metal conductive male socket 3 from its non-anti-false-position column end to achieve the plug-in fit, thereby preventing the occurrence of wear or breakage of the anti-false-position column 21. Considering aspects such as reducing the insertion difficulty and ensuring the alignment accuracy, a chamfer 24 or a fillet (as shown in Figure 7 the figure) can also be provided around the outer edge of the left end face of the insulating column 2 to facilitate the smooth introduction of the insulating column 2 into the plug column 32.

[0027] As a further optimization of the above high-speed data connector structure, a plurality of limiting protrusions 3212 can be evenly distributed on the right side of the assembly stop boss 3211 around the inner peripheral wall of the receiving cavity 321 (as shown in Figure 8 、 9 、10). It is known that the insulating columns 2 are all plastic parts and have a certain elasticity. In this way, during the process of inserting the insulating column 2 into the plug column 32, the side wall of the insulating column 2 undergoes plastic deformation under the action of the abutting force of the above-mentioned limiting protrusions 3212, so as to achieve the engagement with the limiting protrusions 3212 (as shown in Figure 4 the figure), thereby effectively improving the fixed bonding force between the insulating column 2 and the plug column 32 and preventing displacement, crosstalk or detachment during the subsequent use process.

[0028] Figure 5 、 Figure 6 respectively show the front view and the B-B cross-sectional view of the high-speed data connector. It can be seen that a flattened anti-rotation surface 23 can also be provided along the length direction around the peripheral side wall of the above-mentioned insulating column 2 (as shown in Figure 7 the figure), and it corresponds exactly to the above-mentioned assembly stop boss 3211, thereby effectively preventing the insulating column 2 from flipping relative to the metal conductive male socket 3 during the subsequent specific application process and ensuring the smooth execution of the Pin pairing process.

[0029] Considering improving the connection reliability and stability between the metal conductive male socket 3 and the insulating plastic female socket 4, as shown in Figure 3 、 4 the figure, two anti-disengagement annular protrusions 322 can also be provided around the periphery of the plug column 32 and linearly arranged along its axis (as shown in Figure 8 the figure). Correspondingly, an anti-disengagement groove adapted to the above-mentioned anti-disengagement annular protrusions 322 is provided on the inner wall of the plugging cavity of the insulating plastic female socket 4 (not shown in the figure).

[0030] Of course, the number of the above anti - detachment annular protrusions 322 and anti - detachment grooves can also be set to 1, 3, 4, etc. During the design work, it can be specifically set according to the actual design requirements.

[0031] Finally, a limiting post 311 can also extend downward continuously along the bottom wall of the conductive shell body 31 (as shown in Figure 8 ), correspondingly, a limiting hole (not shown in the figure) adapted to the above - mentioned limiting post 311 is opened on the PCB board 1, and subsequent soldering is used to achieve a reliable connection between the metal conductive male seat 3 and the PCB board 1, avoiding the phenomenon of disconnection during its specific application.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
