Description

Cable assembly shield barrel and cable assembly, connector TECHNICAL FIELD

[0001] The utility model relates to connector technical field, concretely relates to a kind of cable assembly shield barrel and cable assembly, connector. BACKGROUND

[0002] High-speed cable is connected with corresponding equipment through connector, such as the high-speed cable assembly disclosed in the Chinese invention patent application with the application publication number CN116505314A, the high-speed cable assembly is cable connector, including differential assembly, middle shell and outer shell body, the middle shell is installed in the outer shell body, the differential assembly has multiple, the differential assembly is inserted into the jack of middle shell, the differential assembly includes cable, grounding clamp, contact piece, insulating sleeve, shielding shell and shielding cover, the cable includes cable main body, the outer side of cable main body is sequentially provided with shielding layer made of aluminum foil and insulating layer, the contact piece includes contact terminal and the fixed block for fixing contact terminal by injection molding, the contact terminal is welded and fixed with wire in cable main body by solder pad, the cross section of shielding shell is U-shaped structure, shielding shell has two side walls opposite with interval and connecting wall connecting two side walls, contact piece and insulating sleeve are embedded in shielding shell, shielding shell forms surrounding to three faces of contact piece and insulating sleeve, shielding cover is buckled at the opening side of shielding shell, a plurality of shielding shell convex edges are arranged at the edge of side wall of shielding shell, shielding cover convex edge is arranged at the side of shielding cover, shielding cover convex edge is embedded between shielding shell convex edge, shielding shell convex edge can limit the function of shielding cover, ensure that shielding cover can be aligned with shielding shell in its width direction and length direction. Wherein, shielding cover is buckled on shielding shell to form shielding barrel, contact piece, insulating sleeve and cable end are located in shielding barrel, shielding barrel, contact piece, insulating sleeve and cable form cable assembly.

[0003] The shielding barrel of the cable assembly of the connector is composed of a shielding cover and a shielding shell, so that when the shielding cover is separated from the shielding shell, the cable end, the contact and the insulating sleeve can be installed in the shielding shell, and then the shielding barrel is shielded by buckling the shielding cover. The contact terminal of the contact is welded to one end of the wire of the cable, and the other end is provided with a clamping spring. The mating connector which is adapted to be plugged into the connector has a pin component corresponding to the cable assembly. The pin component includes a pin and an insulator surrounding the pin. When the cable assembly is plugged into the pin component, the pin of the pin component is inserted between the two clamping springs of the contact terminal in the shielding barrel, and at the same time, a part of the insulator of the pin component is also inserted into the shielding barrel. The end of the shielding barrel away from the cable constitutes a plugging end of the shielding barrel, and the pin component of the mating connector constitutes a mating plugging component. The plugging end is formed with a socket for inserting the mating plugging component. The socket is surrounded by the end of the shielding cover and the end of the shielding shell. In order to avoid the deformation of the flat plate structure of the end of the shielding cover which affects the size of the socket, the end of the shielding cover and the end of the shielding shell are provided with an overlapping structure. As shown in FIG. 1, the end of the shielding cover has an overlapping protrusion 10 which overlaps the top surface of the side wall of the end of the shielding shell. The U-shaped side wall of the shielding shell supports the shielding cover. The shielding cover and the shielding shell are laser welded to realize fixation and electrical conduction. The socket of the shielding barrel is located in the plugging area, and good shielding effect is required. Therefore, the end of the shielding cover near the socket and the end of the shielding shell near the socket need to be provided 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 provided on the overlapping block. The overlapping block and the top surface of the side wall of the shielding shell are welded by providing a welding point on the overlapping block.

[0004] For the shielding barrel of the cable assembly, it is composed of a shielding cover and a shielding shell. The shielding cover is flat, and the shielding shell is U-shaped. The shapes and structures of the shielding cover and the shielding shell are different, and two sets of molds are needed to manufacture them respectively, which is expensive.

[0005] In addition, since the sheet material for manufacturing the shielding shell is usually thin, the top surface of the side wall of the shielding shell is relatively narrow. During laser welding, the overlapping block and the top surface of the side wall of the shielding shell are not fixed due to the deviation of the welding position, and the connection is not reliable. When the pin component of the mating connector is inserted, the end of the shielding cover and the end of the shielding shell are separated due to the opening force of the socket part of the shielding barrel, and the ground return path cannot be formed, which affects the shielding effect.

[0006] High-speed connectors are used for transmitting high-speed signals, and high shielding between signals is required. Existing high-speed cable connectors, such as a high-speed cable connector disclosed in a Chinese patent application publication No. CN117080809A, include a connector housing, and a plurality of pairs of contact pieces are fixedly installed on the front part of the connector housing. Each pair of contact pieces forms a differential pair. The front end of each contact piece is a plug-in end for plugging with an adapter connector, and the rear end is a connection end for connecting with a cable. The rear end of each differential pair is connected with a cable. The cable includes two core wires for transmitting differential signals, an insulation layer wrapped outside the core wires, a shielding layer wrapped outside the insulation layer, and an insulation outer skin wrapped outside the shielding layer. The two core wires are connected with the two contact pieces of the differential pair to transmit high-speed differential signals. The high-speed cable connector further includes a cable shielding grounding structure. The cable shielding grounding structure includes an upper shielding sheet arranged on the upper side of the connector housing and a lower shielding sheet arranged on the lower side of the connector housing. The upper and lower shielding sheets shield each differential pair from the upper and lower sides, respectively. The upper shielding sheet is provided with an upper pressing structure for pressing downward on the cable shielding layer. The lower shielding sheet is provided with a lower pressing structure for pressing upward on the cable shielding layer. The lower pressing structure corresponds to the upper pressing structure one by one in an up-down manner. Each cable shielding layer is clamped between the upper and lower pressing structures at the corresponding position to achieve shielding grounding.

[0007] In order to achieve reliable contact between the shielding sheet and the cable shielding layer, the connector provides a structure for interference fitting through a clamping groove in Embodiment 3. The upper pressing structure is an upper buckle protruding downward from the lower side of the upper shielding sheet. The upper buckle is provided with a downward-opening upper clamping groove. The lower pressing structure is a lower buckle protruding upward from the upper side of the lower shielding sheet. The lower buckle is provided with an upward-opening lower clamping groove. The clamping grooves are through from front to back. After the upper and lower buckles are buckled together, the upper and lower clamping grooves are clamped on the outside of the cable shielding layer from the upper and lower sides, respectively, to wrap the cable shielding layer. The cable shielding layer is interference-fitted with the clamping grooves, so that the groove walls of the clamping grooves press the cable shielding layer, thereby achieving reliable grounding. The upper and lower pressing structures corresponding to the same cable are each provided with two places to press the cable shielding layer in two places in the cable extension direction, further improving the pressing reliability.

[0008] The connector uses the clamping groove on the buckle to clamp the cable shielding layer to achieve reliable grounding. In order to ensure reliable clamping, the clamping groove usually has a relatively large depth and the groove width also needs to be adapted to the cable. Therefore, in order to process the clamping groove and ensure the structural strength, the size of the buckle is relatively large and vertically suspended inward from the main body of the shielding sheet. The buckle is integrally formed on the main body of the shielding sheet by blanking and bending. After the buckle is formed, a relatively large opening is left on the shielding sheet at the buckle. The opening is open outward and affects the shielding effect.

[0121] For the installation of the cable 1, the contact 3, the insulating sleeve 4 and the shielding cylinder as a whole, the structure of the shielding cylinder that cooperates with the cable 1 prevents the cable 1, the contact 3, the insulating sleeve 4 and the shielding cylinder as a whole from being inserted into the shielding cylinder along the length direction of the shielding cylinder. Therefore, the shielding cylinder is formed by the structure that the second shielding sheet 262 is buckled with the first shielding sheet 261 in the direction perpendicular to the connector plugging direction.
