Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and in particular to a cable assembly shielding barrel, a cable assembly and a connector. Background Art

[0002] The high-speed cable is connected to the corresponding equipment through a connector, such as a high-speed cable assembly disclosed in a Chinese invention patent application with application publication number CN116505314A. The high-speed cable assembly is a cable connector, including a differential assembly, a middle shell and an outer shell. The middle shell is installed in the outer shell. There are multiple differential assemblies. The differential assembly is inserted into the jack of the middle shell. The differential assembly includes a cable, a grounding hoop, a contact, an insulating sleeve, a shielding shell and a shielding cover. The cable includes a cable body, and a shielding layer and an insulating layer made of aluminum foil are sequentially arranged on the outside of the cable body. The contact includes a contact terminal and a plastic injection molded material for fixing the contact terminal. The shielding shell has a U-shaped cross-section, and the shielding shell has two side walls spaced opposite to each other and a connecting wall connecting the two side walls. The contact piece and the insulating sleeve are embedded in the shielding shell, and the shielding shell surrounds the three sides of the contact piece and the insulating sleeve. The shielding cover is buckled on the opening side of the shielding shell, and a plurality of shielding shell convex edges are arranged at the edge of the side wall of the shielding shell, and the shielding cover convex edges are arranged on the side of the shielding cover, and the shielding cover convex edges are embedded between the shielding shell convex edges. The shielding shell convex edges can limit the shielding cover, and ensure that the shielding cover can be aligned with the shielding shell in its width direction and length direction. Among them, the shielding cover is buckled on the shielding shell to form a shielding cylinder, and the contact piece, the insulating sleeve and the cable end are located in the shielding cylinder, and the shielding cylinder, the contact piece, the insulating sleeve and the cable form a cable assembly.

[0003] The shielding cylinder of the cable assembly of the above connector is composed of a shielding shell and a shielding cover, so that when the shielding cover is separated from the shielding shell, the cable end, the contact piece and the insulating sleeve can be installed in the shielding shell, and then the shielding cover is buckled to realize the installation of various components in the shielding cylinder. One end of the contact terminal of the contact piece is welded to the wire of the cable, and the other end is provided with a clamping spring. The adapter connector adapted to the connector has a pin component corresponding to the cable assembly one by one, and the pin component includes a pin and an insulator around the pin. When the cable assembly is plugged with the pin component, the pin of the pin component is inserted between the two clamping springs of the contact terminal in the shielding cylinder, and a part of the insulator of the pin component is also inserted into the shielding cylinder. The end of the shielding cylinder away from the cable constitutes the plug-in end of the shielding cylinder, and the pin component of the adapter connector constitutes the adapter plug-in component, and the plug-in end is formed with a socket for inserting the adapter plug-in component. The socket is surrounded by the end of the shielding cover and the end of the shielding shell. In order to prevent the shielding cover end of the flat structure from being easily deformed and affecting the size of the socket, an overlap structure is set between the end of the shielding cover and the end of the shielding shell, such as Figure 1As shown, the end of the shielding cover 1 has an overlapping protrusion 10, which overlaps the top surface of the side wall of the end of the shielding shell 2, and the top surface of the side wall of the U-shaped shielding shell 2 plays a limiting support role for the shielding cover 1. The shielding cover and the shielding shell are laser welded to achieve fixation and electrical conduction, wherein the socket of the shielding cylinder is located in the plug-in area, which requires a good shielding effect, so the end of the shielding cover close to the socket and the end of the shielding shell close to the socket need to be set with a connection point. Since the end of the shielding cover and the end of the shielding shell are overlapping structures, the connection point is set on the overlapping block, and the overlapping block is welded to the top surface of the side wall of the shielding shell by setting a welding point on the overlapping block.

[0004] However, since the sheet material used to make the shielding shell is usually thicker than the sheet material used to make the shielding shell, the top surface of the side wall of the shielding shell will be relatively narrow. During laser welding, it is easy for the overlap block and the top surface of the side wall of the shielding shell to be poorly welded due to welding position deviation, resulting in unreliable connection. The overlap block and the top surface of the side wall of the shielding shell are not fixed. When the pin component of the adapter connector is inserted, a certain supporting force will be applied to the socket of the shielding tube, causing the end of the shielding cover to be separated from the end of the shielding shell, and a grounding return path cannot be formed, thus affecting the shielding effect.

[0048] The shielding tube of the cable assembly of the utility model is achieved by integrally arranging cantilever arms on both side walls of the shielding shell, and the cantilever arms are located on the side of the shielding cover close to the socket, so that the two cantilever arms are cantilevered toward each other and the cantilever ends are connected, and the two cantilever arms are connected and surrounded by the two side walls and connecting walls of the shielding shell to form a socket of the shielding tube. Compared with the structure in which the end of the shielding cover is overlapped with the side wall of the end of the shielding shell to form a socket, the shielding tube is not restricted by the overlapping structure of the shielding cover and the shielding shell. The connection structure of the two cantilever arms is flexibly arranged, which is convenient for forming a reliable connection, ensuring that a stable grounding return path is formed at the socket, which is beneficial to ensuring the shielding effect.

[0049] Embodiments of the connector of the utility model:

[0050] like Figure 2 As shown, the connector includes a connector housing 200 and a plurality of cable assemblies 100 mounted on the connector housing 200. The connector housing 200 is provided with a mounting hole, and the cable assemblies 100 are inserted into the mounting hole. The cable assemblies 100 are arranged in rows and multiple rows are provided. The multiple cable assemblies 100 in the same row are arranged at intervals. The cable assembly 100 is used to realize the connection between the cable 6 and the corresponding adapter connector. The cable assembly 100 is used to transmit high-speed differential signals.

[0051] like Figure 2 , Figure 3 , Figure 4As shown, the cable assembly 100 includes a cable 6, a shielding cover 1, a shielding shell 2, a contact 3, an insulating sleeve 4 and a fixing body 5. The fixing body 5 is used to fill between the cable 6 and the inner wall of the mounting hole of the connector housing 200 to fix the cable 6. The end of the cable assembly 100 away from the cable 6 constitutes a plug-in end for plugging with the adapter plug-in component of the adapter connector. The shielding cover 1 and the shielding shell 2 are snap-connected to form a shielding cylinder, and the end of the cable 6, the contact 3 and the insulating sleeve 4 are all accommodated in the inner cavity of the shielding cylinder, so that the shielding cylinder can be used to surround and shield the connection part between the cable 6 and the contact 3 and the connection part between the contact 3 and the adapter plug-in component of the adapter connector.

[0052] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the contact member 3 includes a contact terminal 31 and an insulator 32. The contact terminals 31 are arranged in pairs, and the two contact terminals 31 form a differential pair. The contact terminal 31 is fixed to the insulator 32. One end of the contact terminal 31 is provided with a spring clamping structure, and the other end is provided with a welding portion. The cable 6 includes a wire and a shielding layer wrapped around the outer periphery of the wire. There is an insulating layer between the shielding layer and the wire. The welding portion of the contact terminal 31 is used to weld with the wire end of the cable 6. The two contact terminals 31 are respectively welded with two wires of the same cable 6. The spring clamping structure of the contact terminal 31 includes two clamping springs arranged oppositely. The adapter plug-in component of the adapter connector includes a pin and an insulating portion. When the connector is plugged in, the adapter plug-in component is inserted into the shielding cylinder of the cable assembly 100. The shielding cylinder has a socket located at the plug-in end of the cable assembly 100 and for inserting the adapter plug-in component. The two clamping springs of the spring clamping structure of the contact terminal 31 are used to clamp the pin to form a conductive contact.

[0053] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the insulating sleeve 4 has an insulating inner cavity 44 for the spring clamping structure of the contact terminal 31 to penetrate, a clamping platform 321 is provided on the side of the insulator 32 of the contact 3, and a clamping groove 43 is provided on the insulating sleeve 4. After the contact terminal 31 extends into the insulating inner cavity 44, the contact 3 and the insulating sleeve 4 are fixedly connected by the clamping platform 321 and the clamping groove 43. After the end of the cable 6 is welded to the contact terminal 31 and the contact 3 is clamped onto the insulating sleeve 4, the shielding shell 2 and the shielding cover 1 are wrapped around the end of the cable 6, the contact 3, and the insulating sleeve 4. The insulating inner cavity 44 is through along the plug-in direction of the connector. When the cable assembly 100 is plugged into the adapter contact component, the pin of the adapter contact component penetrates into the insulating inner cavity 44 to contact the contact terminal 31, and at the same time, the insulating part of the adapter plug component also extends into the shielding cylinder to form a limited fit with the insulating sleeve 4.

[0054] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, a shielding cover 1 is provided on the shielding shell 2, and the shielding shell 2 includes a U-shaped structure. The shielding shell 2 has two shell side walls 25 spaced opposite to each other and a shell connecting wall 24 connecting the two shell side walls 25. The shielding cover 1 is overlapped on the two shell side walls 25 of the shielding shell 2, that is, it is covered on the opening of the U-shaped structure. After the shielding shell 2 and the shielding cover 1 are connected, a shielding cylinder of a rectangular structure is formed and an inner cavity of the shielding cylinder is surrounded. The length direction of the shielding cylinder of the rectangular structure is consistent with the plug-in direction of the connector, the width direction is consistent with the spacing direction of the two contact terminals 31 of the differential pair, and the thickness direction is perpendicular to its length direction and width direction. The length direction of the shielding shell 2 and the shielding cover 1 is consistent with the length direction of the shielding cylinder. The shielding cover 1 and the shell connecting wall 24 of the shielding shell 2 are spaced opposite to each other in the thickness direction of the shielding cylinder, and the two shell side walls 25 of the shielding shell 2 are spaced opposite to each other in the width direction of the shielding cylinder. A cantilever arm is provided at the end of the shielding shell 2 away from the cable 6, and cantilever arms are respectively provided on the two shell side walls 25 of the shielding shell 2, and the cantilever arms are integrally connected to the top of the corresponding shell side wall 25 away from the shell connecting wall 24, and the two cantilever arms are respectively a first cantilever arm 26 and a second cantilever arm 27, and the cantilever arms have a root connected to the corresponding shell side wall 25 and a cantilevered end, and the first cantilever arm 26 and the second cantilever arm 27 are cantilevered toward each other, that is, they are cantilevered face to face, and the cantilevering direction of the cantilever arm is consistent with the width direction of the shielding tube, and the cantilever arm is formed by bending, and the cantilever modules of the first cantilever arm 26 and the second cantilever arm 27 are connected to the two shell side walls 25. The corresponding parts of the shell connecting wall 24 form a socket for the shielding tube. The cantilever arm is located at the end of the shielding shell 2 close to the socket of the shielding tube and at the side of the shielding cover 1 close to the socket, which does not affect the assembly of the cable 6, the contact piece 3 and the insulating sleeve 4 in the shielding shell 2. At the same time, the two cantilever arms are connected and connected with the two shell side walls 25 and the shell connecting wall 24 of the shielding shell 2 to form the socket of the shielding tube, so that the part surrounding the socket will not be restricted by the overlapping structure of the shielding cover 1 and the shielding shell 2. The connection structure of the two cantilever arms is flexibly arranged, which is convenient for forming a reliable connection, ensuring that a stable grounding return path is formed at the socket, which is beneficial to ensuring the shielding effect.

[0055] For the installation of the cable 6, the contact piece 3, the insulating sleeve 4 as a whole and the shielding cylinder, the structure of the shielding cylinder matching the cable 6 will prevent the cable 6, the contact piece 3, and the insulating sleeve 4 from penetrating into the shielding cylinder as a whole along the length direction of the shielding cylinder. Therefore, the shielding cylinder is formed by setting a structure in which the shielding cover 1 and the shielding shell 2 are buckled in a direction perpendicular to the connector plugging direction. When the shielding cover 1 is not buckled onto the shielding shell 2, the end of the cable 6, the contact piece 3, and the insulating sleeve 4 can be installed into the shielding shell 2 from the side, and then the shielding cover 1 can be buckled. The length of the shielding cover 1 is much larger than the size of the cantilever arm in the length direction of the shielding shell 2, so that the shielding shell 2 has a sufficiently large opening to meet the installation space requirements.

[0056] The end faces of the cantilevered ends of the first cantilevered arm 26 and the second cantilevered arm 27 are butted against each other, and the side faces of the first cantilevered arm 26 and the second cantilevered arm 27 along the thickness direction of the shielding tube are flush, so as to facilitate the insertion of the cable assembly 100 into the connector housing 200. The cantilevered end of the second cantilevered arm 27 is provided with an embedding protrusion, and the cantilevered end of the first cantilevered arm 26 is provided with an embedding groove for the embedding protrusion to fit in, the embedding groove is a dovetail-shaped groove with a small mouth and a large belly, and the embedding protrusion is a dovetail-shaped protrusion, the end face of the cantilevered end of the first cantilevered arm 26 includes the groove wall surface of the embedding groove, and the end face of the cantilevered end of the second cantilevered arm 27 includes the side face of the embedding protrusion matching the groove wall surface of the embedding groove. When the first cantilever arm 26 and the second cantilever arm 27 are connected, the embedding protrusion on the second cantilever arm 27 is pressed into the embedding groove from one side in the thickness direction of the shielding tube, and the first cantilever arm 26 and the second cantilever arm 27 are riveted closed, so that the first cantilever arm 26 and the second cantilever arm 27 are fixedly connected, and when the adapter plug-in component is plugged into the cable assembly 100 and the socket of the shielding tube is subjected to external tension, the first cantilever arm 26 and the second cantilever arm 27 will not be detached.

[0057] The shielding cover 1 is provided with an avoidance groove at one end close to the cantilever arm. There are two avoidance grooves. The two avoidance grooves and the two cantilever arms form two avoidance windows 202. The avoidance windows 202 correspond to the ends of the clamping springs of the contact terminal 31, so as to avoid when the pin of the adapter plug component is inserted between the two clamping springs of the contact terminal 31 and the ends of the clamping springs are tilted. The shielding cover 1 is provided with an intermediate connecting portion 17 at the portion between the two avoidance grooves. The intermediate connecting portion 17 is located at the edge of the shielding cover 1 close to the cantilever arm and corresponds to the joint of the first cantilever arm 26 and the second cantilever arm 27. The intermediate connecting portion 17 is connected to the end surface joint portion of the cantilevered ends of the two cantilever arms. A connecting welding point 201 is provided at the intersection of the intermediate connecting portion 17, the first cantilever arm 26 and the second cantilever arm 27, so that the three are connected by welding, which is conducive to the reliable fixation of the two cantilever arms and the reliable connection of the shielding cover 1 and the shielding shell 2. In order to prevent the connection solder joint 201 from protruding, a groove is provided at the docking position of the first cantilever arm 26 and the second cantilever arm 27 near the middle connecting part 17. The thickness of the middle connecting part 17 is less than the thickness of the shielding cover 1 body, so that a solder joint avoidance groove 28 is formed at the welding point between the shielding cover 1 and the two cantilever arms to prevent the connection solder joint 201 from protruding from the side plane of the shielding cover 1 and the cantilever arm body, thereby facilitating the assembly of the cable assembly 100.

[0058] The edges of both sides of the shielding cover 1 in the width direction are respectively provided with a plurality of first grooves 14 and first protrusions 15, and a first groove 14 is formed between two adjacent first protrusions 15. The edges of the shell sidewalls 25 of both sides of the shielding shell 2 away from the shell connecting wall 24 are provided with a plurality of second protrusions 251, and a second groove 252 is formed between two adjacent second protrusions 251. When the shielding sheet is buckled onto the shielding shell 2, the first protrusion 15 is inserted into the corresponding second groove 252, and the second protrusion 251 is inserted into the corresponding first groove 14. The protrusions and the grooves form a concave-convex matching structure to ensure the relative position of the shielding cover 1 and the shielding shell 2, so that the shielding cover 1 and the shielding shell 2 overlap each other to support each other. A welding portion is provided at the matching position of the first groove 14 on the shielding cover 1 and the second protrusion 251 on the shielding shell 2, so as to facilitate the welding operation of the shielding cover 1 and the shielding shell 2 and ensure electrical conduction through welding. In order to prevent the heat generated during welding from affecting the plastic insulating sleeve 4, a heat-avoiding groove 42 is provided on the edge of the insulating sleeve 4 at a position corresponding to the welding part to increase the distance between the insulating sleeve 4 and the welding part to avoid heat radiation damage and carbonization of the insulating sleeve 4 during welding.

[0059] A card slot 253 is provided on the shell side wall 25 of the shielding shell 2, and a card connection protrusion 322 is also provided on the side of the insulator 32 of the contact member 3. The card slot 253 allows the card connection protrusion 322 on the insulator 32 to be inserted along the thickness direction of the shielding cylinder to fix the insulator 32 to the shielding shell 2. The structure is simple and the card connection operation is convenient. A first positioning window 16 is provided at one end of the shielding cover 1 close to the plug-in end of the cable assembly 100, and a second positioning window 241 is provided at one end of the shielding shell 2 close to the plug-in end of the cable assembly 100. Positioning bosses 41 are respectively provided on the outer sides of the insulating sleeve 4 in the thickness direction. The positioning bosses 41 can be inserted into the positioning windows to position the insulating sleeve 4 on the shielding cylinder.

[0060] The end of the shielding cover 1 near the rear of the cable assembly 100 is provided with a first clamping claw 11, a first wire harness portion 12, a connecting tongue, and a contact groove 13 in sequence, and the end of the shielding shell 2 near the rear of the cable assembly 100 is provided with a second clamping claw 21, a second wire harness portion 22, and an abutment platform 23 in sequence. The shielding layer of the cable 6 can be clamped by clamping claws on two opposite sides of the shielding tube in the width direction. The wire harness portion is a bent structure, and a wire harness groove is formed by the wire harness portions on two opposite sides of the shielding tube in the width direction. The cable 6 passes through the center. The wire harness groove on the shielding cover 1 and the wire harness groove on the shielding shell 2 can fix the position of the cable 6 and protect the shielding layer of the cable 6. The connecting tongue on the shielding cover 1 is tilted inward, and the abutment platform 23 on the shielding shell 2 corresponds to the connecting tongue to form a top pressure contact with the shielding layer of the cable 6. The contact groove 13 is arranged on the bending piece on the shielding cover 1.
