DETAILED DESCRIPTION

[0039] The features and performance of the present application are further described below in connection with the embodiments.

[0040] The present application is based on an ideal transmission model of high-speed signals, and the structure of the insulation sleeve in the male terminal module is improved, so that the insulation sleeve is arranged on the front side of the insulation part and spaced from the insulation part, so that at least part of the overhanging section of the male contact piece is insulated and isolated from the shielding cylinder by air, thereby improving the high-speed transmission performance of the male terminal module.

[0041] Based on the above design concept, the utility model provides a plurality of different embodiments for illustration.

[0042] In a basic embodiment, the male connector comprises a male connection module 1, which is a high-speed connection module, comprising a shielding cylinder, a terminal module 13 fixedly installed in the shielding cylinder, and an insulating sleeve 14. As an improved invention, the structure of the terminal module 13 can be the same as that of the terminal module 13 in the prior art, and this will not be described in detail. The key is that the insulating sleeve 14 is located on the front side (the side close to the insertion direction) of the insulating part 130 of the terminal module 13, and is arranged in a spaced manner between the insulating sleeve 14 and the insulating part 130. The position of the insulating sleeve 14 is such that the front end of the overhanging section 131 of the male contact piece extends to the rear end position of the insulating cylinder body 142. In this way, the entire overhanging section or most of the overhanging section 131 of the male contact piece can be isolated from the shielding cylinder by air insulation, and the signal transmission performance of the male connection module 1 can be improved.

[0043] On the basis of the above embodiment, the overall form of the shielding cylinder can be similar to that of the prior art, that is, the shielding cylinder is a cylindrical structure with a rectangular cross-section, comprising a U-shaped bottom shell portion 12 and a flat plate-shaped cover portion 11 fixedly buckled at the opening of the bottom shell, the two portions being buckled to wrap the terminal module 13 and the insulating sleeve 14 inside, and the insulating sleeve 14 comprising an insulating cylinder body 142 with a rectangular cross-section and mounting lugs 143 arranged on opposite sides of the insulating cylinder body 142. The shielding cylinder is provided with a clamping groove 112 on the cylinder wall corresponding to the mounting lugs 143, so that the mounting lugs 143 can be clamped in to fix the insulating sleeve 14. In this way, detachable assembly between the shielding cylinder and the insulating sleeve 14 can be achieved. Of course, in other embodiments, the insulating sleeve 14 can be fixed to the shielding cylinder in a non-detachable manner, such as by adhesive bonding, or by providing a barb structure on the shielding cylinder, and then by inserting the barb structure into the cylinder wall of the insulating sleeve 14 to achieve fixed assembly after forcibly assembling the insulating sleeve 14 into the shielding cylinder.

[0044] In the above embodiment, when the mounting lugs 143 and the clamping grooves 112 are used to achieve assembly between the shielding cylinder and the insulating sleeve 14, the mounting lugs 143 can be arranged on both sides in the width direction of the insulating sleeve 14 and assembled with the clamping grooves 112 on the opposite parallel side walls of the bottom shell portion 12. Figures 8-12In the shown embodiment, the mounting lugs 143 are arranged on opposite sides of the insulating cylinder 142 in the thickness direction, and the bottom wall of the bottom shell part 12 of the shielding cylinder and the cover plate part 11 are respectively provided with clamping grooves 112, and the mounting lugs 143 are respectively assembled with the U-shaped bottom shell part 12 and the cover plate part 11 of the shielding cylinder, so that the insulating sleeve 14 can be conveniently put into the bottom shell part 12, and the insulating sleeve 14 is fixed in the shielding cylinder by the relative buckling of the cover plate part 11 and the bottom shell part 12.

[0045] On the basis of the above-mentioned embodiment, the mounting lugs 143 can be arranged on the two sides of the insulating cylinder 142 in the thickness direction, or as shown, the mounting lugs 143 are suspended rearward from the rear end face of the insulating cylinder 142, and Figure 10 As can be seen from the figure, the front end of the male contact piece is suspended to the position where the mounting lugs are located. Figures 10-11

[0046] On the basis of the above-mentioned embodiment, in a more preferred embodiment, the insulating cylinder 142 is provided with a ring-shaped conductive structure in a plane perpendicular to the front-rear direction, the conductive structure is in electrical conduction with the shielding cylinder, and the inner edge is closer to the male contact piece than the inner side of the shielding cylinder. In this way, the distance between the male contact piece and the grounding component can be shortened by conductive contact, thereby improving the signal transmission performance.

[0047] In an embodiment, the conductive structure can be a metal ring poured in the insulating cylinder 142, which is consistent with the cross-sectional shape of the insulating cylinder 142, the outer edge of the metal ring is flush with the outer surface of the insulating cylinder 142, or slightly protrudes from the outer surface of the insulating cylinder 142, so as to be in electrical conduction with the inner wall surface of the shielding cylinder, and the inner edge of the metal ring is close to the inner surface of the insulating cylinder 142 but does not expose the inner surface of the insulating cylinder 142, so as to ensure insulation.

[0048] Considering that when the male contact piece and the mating contact piece are inserted, the mating contact piece is inserted between the pair of male contact pieces, and the contact part of the male contact piece is pressed by the mating contact piece and approaches the shielding cylinder, at this time, the distance from the contact part to the shielding cylinder is smaller than the distance from the rear suspension section 131 of the contact part to the shielding cylinder, in order to make the distance between the signal transmission line and the grounding component as uniform as possible on the signal transmission line, in a preferred embodiment, the conductive structure is located at the rear side of the contact part.

[0049] ​In order to facilitate processing and manufacturing, in a preferred embodiment, the annular conductive structure is a near-ground conductive transition layer provided on at least one end surface of the insulating barrel 142. When the conductive structure is arranged at the rear side position of the contact part, a near-ground conductive plating layer can be arranged on the rear end surface of the insulating barrel 142. The electrical connection between the near-ground conductive plating layer and the shielding barrel can be achieved by applying conductive glue between the end surface of the insulating barrel 142 and the shielding barrel, or in an embodiment, the outer surface of the insulating barrel 142 is provided with a transition conductive transition layer, the transition conductive transition layer is connected with the near-ground conductive transition layer, and the near-ground conductive transition layer is electrically connected with the shielding barrel through the transition conductive transition layer. In this way, by controlling the plating area of the conductive plating layer, it is more convenient to achieve.

[0050] In addition, more specifically, in the embodiment as shown in Figure 12 The inner part of the insulating barrel 142 is provided with an intermediate partition plate 144 connected to the two side barrel walls in the thickness direction at the middle position in the width direction. The intermediate partition plate 144 extends from the rear end of the insulating barrel 142 to the front and extends to the middle position. The inner cavity of the insulating barrel 142 is divided into two separate cavities parallel in the width direction by the intermediate partition plate 144. The inner sides of the upper and lower side barrel walls of the insulating barrel 142 are provided with sunken platform structures 145 at the front side position of the intermediate partition plate 144. By arranging the sunken platform structures 145, the size in the upward and downward direction at this position is increased. The front edge of the sunken platform structure 145 has a guide slope, which facilitates the insertion of the contact piece.

[0051] The embodiment of the male connection module 1 of the utility model has the same structure as the male connection module 1 in the embodiment of the male connector introduced above, and this will not be described again.

[0052] The above is only a preferred embodiment of the utility model, and does not limit the utility model.
