Detailed Description

In the description of the present invention, it should be understood that the terms "left", "right", "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

The contents of the present invention will be further described in detail with reference to the specific embodiments, and fig. 2, fig. 3 and fig. 4 respectively show an assembly view, a top view and an a-a sectional view of the medium-high speed data connector of the present invention, and it can be seen that the medium-high speed data connector mainly comprises several parts, such as a PCB board 1, an insulating column 2, a metal conductive male seat 3, an insulating plastic female seat 4 and a wire 5. The lead 5 is electrically connected to the PCB board 1 and is inserted into the insulating column 2. The metal conductive male socket 3 includes a conductive shell body 31 and a plug-in post 32. The plug-in post 32 is formed by extending the right sidewall of the conductive shell body 31 to the right, and is provided with an accommodating cavity 321 therein for inserting and adapting the insulating post 2. The metal conductive male socket 3 is inserted and butted with the insulating plastic female socket 4 along the left and right direction by means of the insertion column 32. A fool-proof post 21 (shown in fig. 7) is provided on the right end face of the insulating post 2. An assembly stop boss 3211 is provided on the inner sidewall of the receiving cavity 321, and correspondingly, an abutting step 22 (shown in fig. 7) is provided on the outer sidewall of the insulating column 2. When the insulating column 2 is inserted into position relative to the accommodating cavity 321 along the right-to-left direction, the abutting step 22 abuts against and is matched with the assembling stop boss 3211. In this way, it is effectively ensured that the insulating column 2 occupies the correct assembly position inside the metallic conductive male socket 3, thereby improving the assembly accuracy.

In addition, in the above embodiment, the insulation column 2 is inserted into the metal conductive male socket 3 from the non-fool-proof column end thereof to achieve the insertion fit, so as to prevent the fool-proof column 21 from being worn or broken. In order to reduce the difficulty of insertion and ensure the alignment accuracy, a chamfer 24 (as shown in fig. 7) may be provided around the outer edge of the left end face of the insulating cylinder 2 to facilitate the smooth introduction of the insulating cylinder 2 into the mating cylinder 32.

As a further optimization of the above-mentioned high-speed data connector structure, a plurality of limiting protrusions 3212 (shown in fig. 8, 9 and 10) may be uniformly distributed around the periphery of the inner sidewall of the accommodating cavity 321 and at the right side of the fitting stop boss 3211. As known, the insulating column 2 is a plastic part, and has a certain elasticity, so that, in the process of inserting the insulating column 2 into the inserting column 32, the sidewall of the insulating column 2 is plastically deformed under the action of the abutting force of the limiting protrusion 3212, so as to realize the embedding with the limiting protrusion 3212 (as shown in fig. 4), thereby effectively improving the fixing binding force between the insulating column 2 and the inserting column 32, and preventing the displacement and play or separation in the later use process.

Fig. 5 and fig. 6 respectively show a front view of the high-speed data connector and a cross-sectional view B-B thereof, and it can be seen that a flattened rotation-stopping surface 23 (as shown in fig. 7) may be further disposed around the peripheral side wall of the insulating post 2 along the length direction thereof, and directly faces the assembly position-stopping boss 3211, thereby effectively preventing the insulating post 2 from turning over relative to the metal conductive male socket 3 in the subsequent specific application process, and ensuring smooth execution of the Pin mating process.

In view of improving the connection reliability and stability of the metal conductive male socket 3 and the insulating plastic female socket 4, as shown in fig. 3 and 4, two anti-drop annular protrusions 322 may be further disposed around the periphery of the plug column 32 and arranged in a linear array along the axial direction thereof (as shown in fig. 8), and accordingly, an anti-drop groove (not shown in the figure) adapted to the anti-drop annular protrusion 322 is disposed on the inner wall of the plug cavity of the insulating plastic female socket 4.

Of course, the number of the anti-slip ring-shaped protrusions 322 and the anti-slip grooves may also be set to 1, 3, 4, etc., and the setting may be specifically performed according to the actual design requirement when the design work is performed.

Finally, a limiting post 311 (as shown in fig. 8) may extend downwards along the bottom wall of the conductive shell body 31, and correspondingly, a limiting hole (not shown) adapted to the limiting post 311 is formed on the PCB 1, and then reliable connection between the metal conductive male socket 3 and the PCB 1 is achieved by soldering, so as to avoid a disengagement phenomenon during a specific application process.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
