Description

Technical Field

[0001] The invention relates to the field of parts of connection devices, and in particular to a terminal module and a male end plug-in module. Background Art

[0002] As communication equipment develops towards miniaturization, high density and high speed, high-speed cable connectors are increasingly used. Figure 1-3 The structure of each part of the male end plug-in module 1 in the high-speed cable connection assembly is shown. The existing male end plug-in module 1 mainly includes a terminal module 13, an insulating sleeve 14 and a shielding tube 11. The terminal module 13 includes an insulating component 130 (i.e., a block-shaped body) and a male end contact piece injection-molded in the insulating component 130. The two ends of the male end contact piece extend from the two ends of the insulating component 130 respectively. The rear end of the male end contact piece extending from the insulating component 130 is a wiring terminal. The male end contact piece extends from the front end of the insulating component 130 by one end to form an overhanging section 134. The front end of the overhanging section 134 has a contact portion 135 for conductive contact with the adapter contact piece. The overhanging sections 134 are usually arranged in pairs, and an insertion space for inserting the adapter contact piece is formed between the contact portions 135 at the front ends of the same pair of overhanging sections 134. The wire core of the high-speed cable part is connected to the terminal on the terminal module 13. The insulating sleeve 14 includes a hollow rectangular body, one end of which is used for the adapter female contact to extend into the plug-in port, and the other end has clamping arms extending on both sides in the width direction for clamping with the two sides in the width direction of the insulating component 130.

[0003] As shown in Figure 3, the shielding tube 11 of the existing male plug-in module is a split structure, including a U-shaped bottom shell 113 and a flat cover plate 114 fixedly buckled at the opening of the bottom shell 113. The two parts are buckled to wrap the terminal module 13 and the insulating sleeve 14. A card slot that cooperates with the limiting protrusion 112 on the shielding tube is provided on the side of the clamping arm of the insulating sleeve 14 facing the shielding tube 11, and a limiting protrusion 140 is provided on the side in the thickness direction of the insulating sleeve 14. The two side surfaces in the thickness direction of the shielding tube 11 are respectively provided with a limiting protrusion 112 for cooperating with the corresponding side of the insulating component 130 and a limiting hole 110 for cooperating with the limiting protrusion 140, thereby realizing the installation of the shielding tube 11 and the terminal module 13. When the male-end plug-in module 1 is plugged into the female-end plug-in module 2, the matching contact of the female-end plug-in module 2 extends from the plug-in port into the insulating sleeve 14 and plugs into the male-end contact of the male-end plug-in module 1. The above-mentioned existing male-end plug-in module has a high degree of integration and a small volume, and the plug-in position is fully shielded by the shielding tube 11, thereby avoiding crosstalk between different signals.

[0004] However, in the above-mentioned prior art, the insulating sleeve 14 extends forward from the terminal module 13 to the front end of the shielding tube 11, and completely wraps the overhanging section 134 of the male contact and the position where the contact portion 135 and the adapter contact are inserted. Although this structural form ensures the insulation reliability between the male contact and the shielding tube 11, the ideal high-speed signal transmission model is to set a full shielding structure surrounding the transmission line at a suitable distance (not too large, preferably small) outside the signal transmission line, and the signal transmission line and the full shielding structure are isolated by air insulation. The structural form of the above-mentioned existing design is not conducive to high-speed signal transmission. Summary of the invention

DETAILED DESCRIPTION

[0028] The present invention proposes an improved technical solution to the problems existing in the above technical solution. The core concept of the present invention is: side longitudinal beams extending forward to the front side of the contact part are respectively arranged on the left and right sides of the block body, and a plug-in guide frame is arranged on the front side of the two side longitudinal beams. The frame holes of the plug-in guide frame are used to guide the insertion of the adapter contact and plug it into the contact part of the male contact. The side longitudinal beams only extend forward from the two sides of the overhanging section, and the plug-in guide frame on the front side of the side longitudinal beams is also located on the front side of the contact part. In this way, the air insulation area between the overhanging section of the signal transmission route and the shielding tube is expanded, and the signal transmission performance of the male plug-in module can be improved during signal transmission.

[0029] Based on the above concept, a terminal module of the present invention includes an insulating component and a male contact fixed in the insulating component, wherein the insulating component includes Figure 4The block body 131 shown, the male contact has an overhanging section 134 extending forward from the front end of the block body 131, and the front end of the overhanging section 134 has a contact portion 135 for plugging with the adapter contact. The left and right sides of the block body 131 are respectively provided with side longitudinal beams 132 extending forward to the front side of the contact portion 135, and the front side of the side longitudinal beam 132 is connected to a plug-in guide frame 133, and the frame hole of the plug-in guide frame 133 is used to guide the adapter contact to be inserted and plugged with the contact portion 135 of the male contact. At this time, it is not necessary to provide a clamping structure for clamping with the clamping arm of the insulating sleeve on the left and right sides of the block body 131, so as to avoid the wire air gap at the clamping position due to the clamping of the two, so as to avoid the wire resonance phenomenon at this place, and ensure the high-speed transmission of the signal. At the same time, the side longitudinal beam 132 only extends forward from both sides of the overhanging section 134, and the plug-in guide frame 133 on the front side of the side longitudinal beam 132 is also located in front of the contact portion 135. In this way, the air insulation area between the overhanging section 134 and the shielding tube 11 on the signal transmission route is expanded, which can improve the signal transmission performance of the male end plug-in module during signal transmission.

[0030] The thickness of the side longitudinal beam 132 in this embodiment is less than the thickness of the fixed sleeve 131. Figure 4 , Figure 5 , Figure 6 As shown, one of the two sides in the thickness direction of the side longitudinal beam 132 is flush with the fixed sleeve 131, and a positioning protrusion 137 for abutting against the shielding cylinder 11 is provided on the other side in the thickness direction of the side longitudinal beam 132, corresponding to the position of the contact portion 135. The positioning protrusion 137 can prevent the side longitudinal beam 132 from vibrating due to improper installation or impact, and ensure the stability of the side longitudinal beam 132 located in front of the fixed sleeve 131.

[0031] In this embodiment, if Figure 5 , Figure 6 As shown, the insulating component is an upper and lower petal structure in the thickness direction, including an upper petal 12 and a lower petal 15. Among the two pairs of male contact pieces fixed in the insulating component, the two on the same side in the thickness direction of the insulating component are on the corresponding same petal, and the upper and lower petals both have upper and lower side longitudinal beams, and the front ends of the upper and lower side longitudinal beams are connected to upper and lower cross beams. After the upper and lower petals are interlocked with each other, the upper and lower side longitudinal beams on the corresponding sides jointly constitute the side longitudinal beams 132, and the upper and lower cross beams and the side longitudinal beams jointly form the plug-in guide frame 133. The upper and lower petal settings make the insulating component easier to process and shape during the manufacturing process, saving manufacturing costs. At the same time, when the male contact piece is damaged, only the petal on the corresponding side of the insulating component needs to be replaced, saving maintenance and replacement costs. In addition, in other embodiments, the insulating component can also be an integrated structure, and the male contact piece and the insulating component are integrally injection molded.

[0032] In this embodiment, the upper and lower petals are plugged and buckled together through a concave-convex matching structure. At this time, a protrusion can be set on one of the upper and lower petals, and a concave part can be set on the other petal, and the upper and lower petals can be buckled together through the cooperation of the protrusion and the concave part. In addition, in other embodiments, the upper and lower petals can also be connected by screws. Of course, in another embodiment, the upper and lower petals can also be connected by bonding.

[0033] In this embodiment, the concave-convex matching structure includes a plug hole 151 on one petal and a plug post on the other petal. Figure 6 As shown, the lower petal 15 is provided with an insertion hole 151, and correspondingly, the upper petal 12 is provided with a corresponding insertion column. The insertion hole 151 and the insertion column have simple structures, and after the two are plugged in, the upper and lower petals can be reliably buckled. In addition, in other embodiments, the concave-convex matching structure can also be a positioning groove on one petal, and a protrusion on the other petal that can extend into the positioning groove.

[0034] In this embodiment, the cross-sectional shape of the plug-in column is a plum blossom shape. The plug-in column needs to be interference-fitted with the plug-in hole 151. When the plug-in column of the plum blossom shape is inserted, the circumferential area for interference-fitting with the plug-in hole 151 is small, so it is more convenient and labor-saving during installation. In addition, in other embodiments, the cross-sectional shape of the plug-in column can also be circular, as long as the plug-in column can be inserted into the plug-in hole 151 to achieve the buckling of the upper and lower petals 15.

[0035] In this embodiment, the insulating component further includes an intermediate longitudinal beam 139 between the left and right pairs of male contact pieces, and the front end of the intermediate longitudinal beam 139 is connected to the plug-in guide frame 133. The intermediate longitudinal beam 139 can also enhance the structural strength of the insulating component and improve the structural reliability of the insulating component.

[0036] Another aspect of the present invention further provides a male end plug-in module 1, the male end plug-in module 1 comprises: Figure 7-Figure 9 The shielding tube 11 and the terminal module 13 are shown. Since the terminal module 13 is the same as the embodiment of the terminal module 13 described above, they are not described again here.

[0037] In a preferred embodiment, if Fig.10 , Fig.11 , Fig.13 As shown, the shielding cylinder 11 is provided with an abutting structure for abutting with the shielding shell of the female plug-in module 2. In this way, the reliability of the contact between the shielding cylinder 11 of the male plug-in module and the shielding shell of the female plug-in module 2 is ensured. In addition, in other embodiments, the shielding cylinder may not be provided with an abutting structure, and the shielding contact between the two is achieved by the surface contact between the cylinder wall of the shielding cylinder and the shell wall of the shielding shell.

[0038] In a preferred embodiment, the abutment structure is located on the upper wall and / or the lower wall of the shielding cylinder 11. Fig.12 As shown, shielding shell spring pieces 16 are provided on the left and right side walls of the shielding shell of the female end plug-in module 2. When the male end plug-in module 1 is inserted into the shielding shell, the shielding shell spring pieces 16 abut the shielding cylinder 11 to achieve shielding contact between the shielding cylinder 11 and the shielding shell. In this embodiment, an abutment structure is provided on the upper cylinder wall and / or the lower cylinder wall of the shielding cylinder 11, so that the shielding cylinder 11 can reliably contact the shielding shell at the upper cylinder wall and / or the lower cylinder wall, and the reliability of the contact between the shielding shell and the shielding cylinder 11 can be further improved. Of course, in other embodiments, the abutment structure can also be on the left cylinder wall and / or the right cylinder wall of the shielding cylinder 11, as long as the reliability of the contact between the shielding cylinder 11 and the shielding shell can be achieved.

[0039] exist Fig.11 In the illustrated embodiment, the abutment structure is a cantilevered spring sheet 16 disposed at the front end of the shielding tube 11 and which can be pressed down when subjected to force. The spring sheet 16 has a simple structure and can be pressed down when subjected to force, so there will be no large resistance when the shielding tube 11 and the shielding shell are installed, the installation is convenient, and reliable abutment between the shielding tube 11 and the shielding shell can be achieved. In addition, in other embodiments, the abutment structure can also be an abutment spring sheet disposed at the front end of the shielding tube, which is inclined outward and cantilevered backward. After the shielding tube is forcibly installed in the shielding shell, the abutment spring sheet abuts against the wall of the shielding shell to achieve shielding contact between the two. It is easy to imagine that the abutment structure can also be a lower recess disposed on the shielding tube. In this case, a corresponding spring sheet needs to be disposed on the shielding shell, and the lower recess on the shielding tube contacts the spring sheet disposed on the shielding shell to achieve abutment between the shielding tube and the shielding shell.

[0040] In a preferred embodiment, the spring sheet 16 is provided with a recessed portion 161 for cooperating with the convex bump 20 on the shielding shell of the female plug-in module 2. When the convex bump 20 on the shielding shell is sunken into the recessed portion 161, the relative displacement between the shielding tube 11 and the shielding shell caused by impact can be avoided, and the reliability of the abutment between the shielding tube 11 and the shielding shell can be further improved.

[0041] In such Fig.10 , Fig.11 , Fig.13In the embodiment shown, the upper and lower walls of the shielding tube 11 are provided with protruding protrusions 115 protruding toward the inner cavity of the shielding tube 11 at the front side of the contact portion 135. After the adapter contact is inserted between the contact portions 135, the two paired overhanging sections 134 are pushed to opposite sides by the adapter contact to keep the adapter contact pressed, so the distance from the overhanging section 134 to the wall of the shielding tube 11 on the same side is smaller than the distance from the adapter contact to the wall. Therefore, in this embodiment, the protruding protrusion 115 is provided at the front end of the contact portion 135, so that after the male contact and the adapter contact are plugged in, the distance from the overhanging section 134 to the wall of the shielding tube 11 on the same side can be reduced to the difference between the distance from the adapter contact to the wall, and become closer, so that on the extension path of the signal transmission line, the distance between the outer ground shield and the signal transmission line is more uniform, which is conducive to ensuring the quality of signal transmission. In a preferred embodiment, the protrusion near the ground 115 is located at the rear side of the plug-in guide frame 133 and is disposed adjacent to the plug-in guide frame 133. In this way, the distance between the signal transmission route and the ground shield in the area between the contact portion 135 and the front end of the plug-in area of ​​the adapter contact and the rear side of the plug-in guide frame 133 can be made more uniform, thereby ensuring the signal transmission quality in this area. In addition, in other embodiments, when the contact portion is far away from the plug-in guide frame, the protrusion near the ground is also disposed close to the contact portion, that is, the protrusion near the ground is not disposed adjacent to the plug-in guide frame. Of course, it is easy to imagine that in another embodiment, the protrusion near the ground may also be located at the front side of the plug-in guide frame.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the contents of the description and drawings of the present invention should also be included in the protection scope of the present invention.
