[0049] The cable assembly of the utility model utilizes shielding sheets of the same specifications arranged around the center line of the shielding tube to connect and form a shielding tube. The shielding sheets surround an inner cavity of the shielding tube to accommodate cable ends and contact pieces. The shielding sheets have the same specifications and can be manufactured using the same mold, saving mold fees and reducing costs.

[0050] Embodiment 1 of the connector of the present utility model:

[0051] like Figure 1 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 assemblies 100 are used to realize the connection between the cable 1 and the corresponding adapter connector and to transmit high-speed differential signals.

[0052] like Figure 1 , Figure 2 and Figure 3As shown, the cable assembly 100 includes a cable 1, a shielding sheet 2, a contact 3, an insulating sleeve 4 and a fixing body 5, and the fixing body 5 is used to fill between the cable 1 and the inner wall of the mounting hole of the connector housing 200 to fix the cable 1. There are two shielding sheets 2, and the two shielding sheets 2 are connected to form a shielding cylinder. The end of the cable 1, the contact 3 and the insulating sleeve 4 are all accommodated in the inner cavity of the shielding cylinder, so that the shielding cylinder is used to surround and shield the connection part between the cable 1 and the contact 3 and the connection part between the contact 3 and the adapter contact of the adapter connector.

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 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 adapter contact of the adapter connector is a pin. The spring clamping structure of the contact terminal 31 is used to clamp the pin to form a conductive contact when the connector is plugged in. The cable 1 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 1. The two contact terminals 31 are respectively welded with two wires of the same cable 1.

[0054] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 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 through the clamping platform 321 and the clamping groove 43. After the end of the cable 1 is welded to the contact terminal 31 and the contact 3 is clamped onto the insulating sleeve 4, the two shielding sheets 2 are wrapped around the cable 1, the contact 3, and the insulating sleeve 4.

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7As shown, the shielding sheet 2 is an L-shaped structure, and the shielding sheet 2 includes a first side wall 25 and a second side wall 26 that are perpendicular to each other. The first side wall 25 of one shielding sheet 2 is connected to the second side wall 26 of another shielding sheet 2. After the two L-shaped shielding sheets 2 are connected, a rectangular shielding tube is formed and an inner cavity of the shielding tube is surrounded. The length direction of the rectangular shielding tube 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 sheet 2 is consistent with the length direction of the shielding tube. The first side walls 25 of the two shielding sheets 2 are spaced opposite to each other in the thickness direction of the shielding tube, and the second side walls 26 of the two shielding sheets 2 are spaced opposite to each other in the width direction of the shielding tube. The two shielding sheets 2 have the same specifications, the same shape and size, and are arranged around the center line of the shielding tube. The two shielding sheets 2 are arranged in a central symmetric manner. For the installation of the cable 1, contact 3, insulating sleeve 4 and the shielding tube as a whole, the structure of the shielding tube matching the cable 1 will prevent the cable 1, contact 3, and insulating sleeve 4 from penetrating into the shielding tube as a whole along the length direction of the shielding tube. Therefore, the two shielding sheets 2 are buckled together perpendicular to the plug-in direction of the connector and surround the end of the cable 1, the contact 3, and the insulating sleeve 4. The two shielding sheets 2 form the inner cavity of the shielding tube to accommodate the end of the cable 1 and the contact 3. The shielding tube is formed by connecting two shielding sheets 2 of the same specifications. The two shielding sheets 2 have the same specifications and can be made with the same mold, saving mold costs and reducing costs. Moreover, the number of parts is small, which is convenient for assembly operation. When making the L-shaped shielding sheet 2, there are few bending processes, which is convenient for manufacturing.

[0056] The edge of the first side wall 25 of the shielding sheet 2 away from the second side wall 26 is provided with a plurality of first protrusions 251, and a first groove 252 is formed between two adjacent first protrusions 251. The edge of the second side wall 26 of the shielding sheet 2 away from the first side wall 25 is provided with a plurality of second protrusions 262, and a second groove 261 is formed between two adjacent second protrusions 262. The first protrusions 251 on the first side wall 25 correspond to the second grooves 261 on the second side wall 26, and the first grooves 252 on the first side wall 25 correspond to the second grooves 261 on the second side wall 26. 26 corresponds to the second convex part 262 on the first side wall 25. When the two shielding sheets 2 are buckled, the first convex part 251 is inserted into the corresponding second groove 261, and the second convex part 262 is inserted into the corresponding first groove 252. The convex part and the groove form a concave-convex matching structure to ensure the relative position of the two shielding sheets 2, so that the two shielding sheets 2 overlap each other to support each other. The convex part on any shielding sheet 2 constitutes a connecting part that buckles to the groove on the other shielding sheet 2 along the thickness direction of the shielding tube, so that the two shielding sheets 2 are buckled and connected along the thickness direction of the shielding tube, which is convenient for operation. A welding part is provided at the matching place of the first groove 252 on the first side wall 25 and the second convex part 262 on the second side wall 26, so as to facilitate the welding operation of the two shielding sheets 2 and ensure electrical conduction through welding. In order to prevent the heat generated during welding from affecting the insulating sleeve 4 made of plastic material, a heat-avoiding groove 42 is provided on the edge of the insulating sleeve 4 at the position corresponding to the welding part of the two shielding sheets 2, so as to increase the distance between the insulating sleeve 4 and the welding part, and avoid heat radiation damage and carbonization of the insulating sleeve 4 during welding.

[0057] A card slot 260 is provided on the second side wall 26 of the shielding sheet 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 260 allows the card connection protrusion 322 on the insulator 32 to be inserted into the thickness direction of the shielding tube to fix the insulating sleeve 4 and the shielding sheet 2. The structure is simple and the card connection operation is convenient. The cable assembly 100 has a head for plugging with an adapter connector and a tail for connecting the cable 1. A positioning window 253 is provided at one end of the shielding sheet 2 close to the head of the cable assembly 100. A positioning boss 41 is provided on the outer surface of the insulating sleeve 4 in the thickness direction. The positioning boss 41 can be inserted into the positioning window 253 to position the insulating sleeve 4 on the shielding sheet 2.

[0058] The end of the shielding sheet 2 near the rear of the cable assembly 100 is provided with a clamping claw 21, a wire bundling portion 22, a connecting tongue 23, and a contact groove 24. The clamping claws 21 on the two opposite sides in the width direction of the shielding tube can tighten the shielding layer of the cable 1. The wire bundling portion 22 is a bending structure. The wire bundling groove is formed by the wire bundling portions 22 on the two opposite sides in the width direction of the shielding tube. The cable 1 passes through the center, which can fix the position of the cable 1 and protect the shielding layer of the cable 1. The connecting tongue 23 is arranged on the first side wall 25 of the shielding sheet 2. The connecting tongue 23 is tilted inward and can contact the shielding layer of the cable 1. The contact groove 24 is arranged on the bending sheet. The groove wall of the contact groove 24 can contact the shielding layer of the cable 1, and there is a certain amount of extrusion, so as to realize the common ground connection between the shielding sheet 2 and the cable 1. The shielding layer of the cable 1 forms multiple contacts with the shielding sheet 2, which is conducive to reliable shielding conduction.

[0059] When assembling the cable assembly 100, first weld the wire end of the cable 1 to the contact terminal 31 of the contact piece 3, then extend the contact terminal 31 of the contact piece 3 into the insulating inner cavity 44 of the insulating sleeve 4 and clamp the insulator 32 of the contact piece 3 to the insulating sleeve 4; use two L-shaped shielding sheets 2 to wrap the contact piece 3 and the insulating sleeve 4, and the connecting tongue 23 and the contact groove 24 of the shielding sheet 2 are in contact with the shielding layer of the cable 1; then fix the two shielding sheets 2 by welding, and wrap and fix the clamping claws 21 of the two shielding sheets 2 and the cable 1 by the fixing body 5.

[0060] In other implementations, the shielding cylinder may also be a cylindrical structure, in which case the shielding sheet may be an arc-shaped sheet structure, with two or three shielding sheets surrounding the shielding cylinder.

[0061] In other implementation manners, four L-shaped shielding sheets may also be provided, and the four shielding sheets respectively form four corners of the shielding tube.

[0062] In other embodiments, the shielding sheet may also be provided with an insertion hole at the edge of the first side wall, and an insertion tongue at the edge of the second side wall, and the insertion tongue of one shielding sheet may be inserted into the insertion hole of another shielding sheet to achieve a limited fit.

[0063] Embodiment 2 of the connector of the present utility model:

[0064] The connector in this embodiment has the same contact piece, connector housing, and connection structure between the contact piece and the insulating sleeve as those in the above-mentioned embodiment 1, except that the heat-shielding grooves of the shielding sheet and the insulating sleeve are arranged. Specifically, Figure 8 , Figure 9 , Figure 10 , Figure 11As shown, the shielding sheet 2 is a U-shaped structure, and the shielding sheet 2 includes two shielding sheet side walls 201 arranged opposite to each other and a shielding sheet bottom wall 202 connecting the two shielding sheet side walls 201. The two U-shaped shielding sheets 2 form a shielding tube of a rectangular tube structure. The two shielding sheet side walls 201 of the shielding sheets 2 are opposite to each other in the width direction of the shielding tube, and the shielding sheet bottom walls 202 of the two shielding sheets 2 are opposite to each other in the thickness direction of the shielding tube. The shielding sheet side walls 201 of the two shielding sheets 2 are butt-jointed in the thickness direction of the shielding tube. The U-shaped shielding sheet has relatively good structural strength and is not easy to deform. The shielding sheet side wall 201 is provided with a slot for the engaging protrusion on the insulator of the contact piece to be engaged. The shielding sheet side wall 201 is also provided with a limiting protrusion 2011, a limiting groove 2012 and a concave portion 2013. The concave portion 2013 is bent toward the side where the contact piece and the insulating sleeve are located. The concave portion 2013 has an inner side surface facing the contact piece and the insulating sleeve and an outer side surface facing away from the contact piece and the insulating sleeve. When the two shielding sheets 2 are buckled, the limiting protrusion 2011 is engaged with the limiting groove 2012, and the concave portions 2013 of the two shielding sheet side walls 201 are butt-jointed. The limiting protrusion 2011 on one shielding sheet 2 and the limiting groove 2012 on the other shielding sheet 2 constitute a concave-convex matching structure, and the limiting groove 2012 on the shielding sheet 2 constitutes a connecting portion for the other shielding sheet to be buckled. The outer side surfaces of the concave parts 2013 of the two shielding sheet side walls 201 are flush, and a welding portion is provided at the joint of the concave parts 2013 of the two shielding sheet side walls 201. A welding point 20 is provided at the welding portion to fix the two shielding sheets 2. The welding point 20 is provided at the concave portion to prevent the welding point 20 from bulging outward and affecting the assembly of the cable assembly on the connector housing.

[0065] Since the welding point 20 is arranged on the side surface of the shielding tube in the width direction, the heat-avoiding groove 42 on the insulating sleeve 4 is arranged on the side surface of the insulating sleeve 4 in the width direction, and the heat-avoiding groove 42 passes through along the thickness direction of the insulating sleeve 4, so that a larger gap is formed between the insulating sleeve 4 and the welding part to avoid the heat generated during the welding process from damaging the insulating sleeve 4.

[0066] In other implementations, the shielding cylinder may also be divided into two U-shaped shielding sheets in the width direction, so that the cable assembly can be loaded from the side opening of the U-shaped shielding sheet.
