In order to reduce the width of the connector, the terminals are arranged in at least two rows at intervals in the front-back direction of the insulator seat. In order to meet the requirement of high-speed signal transmission, the terminal 6 includes signal terminals 61 and ground terminals 62, two adjacent signal terminals form a differential signal pair 63 for transmitting high-speed differential signals, the differential signal pair is disposed between the adjacent ground terminals, therefore, in the front/rear row of terminals, four terminals are in one group and form a terminal assembly, the terminal assembly array is in one row, correspondingly, the number of cables is the same as that of the terminal assemblies, the cables 3 are double-ground wire differential cables, and each cable is welded with one terminal assembly. Referring to fig. 17, the cable core in each cable includes two ground wires 32 and two signal wires 31, the ground wires 32 are welded to the ground terminal 62, the signal wires 31 are welded to the signal terminals 61, and the terminals in each row are distributed in the form of GSSGGSSG, so that stable transmission of high-speed signals is realized.

All terminal assemblies of the front/rear rows are produced by the same die, the state after the die processing is as shown in fig. 7, all terminals in the terminal assemblies are of an integrally formed structure, the terminals comprise an elastic contact area 601, an assembly holding area 602 and a wiring area 603 which are sequentially connected, the wiring area 603 is welded with a cable 3, the assembly holding area 602 is positioned in a mounting hole 513, the mounting hole 513 is arranged in the insulator seat 51 in a penetrating manner along the vertical direction, and the elastic contact area extends out of the bottom end opening of the mounting hole so as to be in contact with a copper foil contact 72 on the surface of the PCB. As shown in fig. 14, the assembly holding area is extended in the up-down direction, and at least one side of the assembly holding area in the width direction is provided with an interference bump 6021, so that the assembly holding area and the hole wall of the mounting hole are in interference fit to realize the positioning of the terminal; further, the assembly holding area is provided with a limit projection 6022 at least on one side thereof, and the limit projection is in stop fit with the insulator seat limit face 5131 at the side of the lower end of the mounting hole in the upward direction, and plays a limit role in the mounting of the terminal. When the terminal is mounted, the terminal is inserted into the corresponding mounting hole of the insulator seat from bottom to top, the limit convex part 6022 is regarded as being inserted in place when being abutted against the limit surface 5131 of the insulator seat, and then the terminal connection area 603 of the terminal is bent by a bending jig so that the assembly holding area 602 is perpendicular to the terminal connection area 603, thereby enabling the terminal to be in the state shown in fig. 10. As shown in fig. 9, 11 and 12, the wiring area is horizontally arranged along the front-back direction after being bent, the wiring area is clamped in the insulator base, an assembling groove 514 for accommodating the wiring area is formed in the insulator base 51, convex hulls 515 are arranged on the inner walls of two sides of the assembling groove, the wiring area is clamped in the assembling groove, two sides of the wiring area are in interference fit with the convex hulls, so that terminal rebounding caused by internal stress of materials after the terminal is bent is avoided, the wiring area is prevented from being tilted upwards, the terminal after being bent is vertically limited in the insulator base, reliable terminal holding force can be provided, and stable contact conduction of the connector and a PCB is ensured.

As shown in fig. 10, the elastic contact area 601 is an overhanging elastic sheet, which is U-shaped, V-shaped, L-shaped, or the like, that is, has a bent portion, and an elastic contact 6011 is formed at a lower end of the bent portion of the elastic sheet. Preferably, as shown in fig. 16, the lower end surface of the insulator base is provided with an avoiding groove 516, and when the elastic contact region is deformed upwards by the pressure of the PCB, the avoiding groove can accommodate the elastic contact region, so that the height of the elastic contact region protruding from the lower end surface of the insulator base can be effectively reduced, thereby reducing the height of the connector and facilitating the flat design of the connector.

As shown in fig. 17, the terminal areas of each row of terminals are in the same plane, and the ends of the cables horizontally overlap the upper surface of the terminal areas, i.e., the ground wires in the cables are placed on the upper surfaces of the terminal areas of the corresponding ground terminals, and the signal wires are placed on the upper surfaces of the terminal areas of the signal terminals, and then soldering is performed. As shown in fig. 16, in order to facilitate welding, a process recess 517 is formed below the connection region of each row of terminals on the insulator base, and the process recess is used to realize welding and fixing of the cable and the connection region by using laser welding, resistance welding, hot-press welding or other processes; specifically, the ground wire and the signal wire are pressed on the upper surface of the wiring area of the corresponding terminal, and then are heated through a lower process empty groove, so that each cable core of the cable and the corresponding terminal are hot-pressed and fused into a whole; alternatively, the bonding is performed directly on the upper surface of the terminal area by any of the above bonding processes.

With reference to fig. 6, 15, and 16, the terminal in the front row is set as a metal terminal i 6001, the terminal in the rear row is set as a metal terminal ii 6002, each of the metal terminals i and ii is a set of four terminals to form a terminal assembly, and each terminal assembly is correspondingly welded with one cable.

Under the prerequisite of two row at least terminals, because the metal terminal I of front row can certainly cross the metal terminal II of back row on the projection plane with the cable when welding, if two rows of terminals are in same setting height, then the cable of being connected with metal terminal I can shelter from the welding space who occupies back row metal terminal II. And the height of the metal terminal I is set to be higher than that of the metal terminal II, so that an avoidance space is provided for the cable connected to the metal terminal I in the vertical space, and the cable connected with the front row of terminals can cross over the rear row of terminals from the upper part of the rear row of terminals. Through the design, the arrangement height of the front row of terminals is higher than that of the rear row of terminals, and preferably, the difference between the thicknesses of the cables of the metal terminals I and the metal terminals II in the height direction of the insulator seat is 1/2-1 times, so that the high-speed size minimization of the connector can be ensured, and the welding of the rear row of terminals can be facilitated. In addition, because the metal terminals I at the front row are higher than the metal terminals II at the rear row in the height direction of the insulator seat, the terminals at the lower rear row can be welded firstly and the terminals at the front row can be welded secondly during welding, so that the welding efficiency is improved and the welding procedure is simplified.

Furthermore, the front row of terminals can be set to have a certain width dislocation amount compared with the rear row of terminals, and the purpose is to make the cables connected with the metal terminals I abdicate for the welding positions of the rear row of terminal assemblies, and by setting a little abdication, the welding parts of the rear row of terminal assemblies are exposed to a little more on the vertical projection plane, so that the stability and convenience of welding and fixing are facilitated (namely, the periphery of the welding points is interfered by other cables as little as possible). Preferably, the metal terminal i and the metal terminal ii differ by 1/2 to 1 times the cable width in the insulator seat width direction. It should be noted that the effect of reducing the width dimension of the connector can be achieved as long as the displacement amount of the front and rear two rows of terminal assemblies in the width direction is less than one time the width of the terminal assemblies. It is conceivable that if two rows of terminal assemblies are provided and the number of the two rows of terminal assemblies is the same, the amount of width misalignment between the two rows of terminal assemblies is only required to be less than one time the width of the terminals, and if three rows of terminal assemblies are provided, this amount of misalignment can be set again, in short, as long as the total width of the terminal assemblies after misalignment is made smaller than the total width of only one row of terminal assemblies of the same number. By means of the staggered arrangement in the height and width directions, the connector can be guaranteed to achieve the minimum overall dimension under the condition that the cables connected with the front/rear terminals are not overlapped and interfered and the cables are not interfered with the metal terminals.

The structure and size of the metal terminal I and the metal terminal II before being assembled and bent are completely the same, and as shown in FIG. 7, the bending point is slightly adjusted during bending, so that the length of the wiring area on the rear row terminal assembly compared with the wiring area on the front row terminal assembly is the same as the difference in the height direction of the front row terminal assembly and the rear row terminal assembly. Specifically, referring to fig. 16, when the land length of the rear row metal terminal ii is L1, the land length of the front row metal terminal i is L2, and the difference between the land lengths of the front/rear row terminals is L, L is L1 to L2; the height difference of the front/rear row of terminals in the height direction of the insulator seat is set to be H, when L is H, one set of die can be saved, and an automatic assembly line is simplified.

As shown in fig. 15, the high-speed cable connected with the front row of terminals is set as a cable i 301, the high-speed cable connected with the rear row of terminals is set as a cable ii 302, the cables i and ii are uniformly led out from the tail end of the insulator seat, all the cable tail end parts are uniformly led out from the insulator seat side by side, when the cables are led out side by side, all the cables are arranged in a row along the width direction, and then the cables are combined with the metal terminals to be installed in a staggered and separated manner, so that high density, small size and industrial integrity of the connector are realized. In order to facilitate all cables to form a row of wires along the width direction, a row of wire guiding grooves 518 are arranged at the rear end of the insulator seat along the width direction. Because two rows of terminals in the front and back misplace in the left and right directions, under the condition of being led out side by side, cable I needs to be bent towards one side, in order to realize the location of cable I, the welding end of cable I still extends along the front and back direction, a cable positioning groove 519 clamped with the cable is arranged on the insulator seat, and the cable positioning groove is located at the rear end of the front row of terminals, specifically as shown in fig. 8.

In order to enable the connector to transmit signals with higher speed and improve the signal transmission environment, the invention also designs a shielding module 9 assembled in the connector, as shown in fig. 18 and 19, the shielding module comprises an injection molding body 91 and a shielding sheet 92 arranged on the injection molding body, the shielding sheet and the injection molding body are connected into a whole through an insert injection molding process, the injection molding body 91 is a cuboid structural part extending along the width direction of the insulator seat, and the upper end of the injection molding body is convexly provided with a plurality of isolation parts 911 distributed at intervals. The shield plate 92 includes a body 921 and a plurality of elastic terminals 922 connected to the body, each of the elastic terminals being a bent plate-like contact member for elastically contacting a lower surface of a land of the ground terminal. The main part extends the setting along the length direction of the injection molding body, and the elastic terminal distributes in a row in the one end of main part, and the main part is fixed in the injection molding body, and the one end of elastic terminal is the stiff end of connecting the main part, and the other end is for stretching out in the expansion end of the injection molding body, and the expansion end has the shielding contact with ground terminal's wiring district lower surface looks elasticity laminating.

As shown in fig. 20, the insulator base is provided with two mounting grooves 520, the mounting grooves 520 are used for mounting the shielding module, and the two mounting grooves are respectively located below the wiring areas of the front/rear row of terminals. After the cables and the terminals are welded, the shielding module is buckled from the mounting groove formed in the bottom of the insulator seat, and after the shielding module is mounted, the lower surfaces of all the grounding terminals in each row of terminals are contacted with the corresponding elastic terminals, so that the intercommunication and interconnection of all the grounding terminals in each row are realized, the shielding effect of the cable connector is improved, and the transmission performance is improved.

The injection molding body is the plastic body, and the plastic body is electrically conductive plastic or ordinary plastic, and when being electrically conductive plastic, isolation portion has shielding ground connection's effect equally, and isolation portion will be same arrange adjacent differential signal pair in and keep apart, has further reduced the crosstalk between adjacent differential signal pair, has improved shielding effect, makes the high-speed transmission performance of connector better. When the injection molding body is ordinary plastic, then the isolated part does not have electric conductive property, and it does not play the shielding isolation effect between the terminal subassembly hardly, but the elastic terminal of being convenient for fixes a position, and the isolated part of elastic terminal side is equivalent to the fender wall this moment, can be used for keeping off the skew, skew etc. that elastic terminal probably produced in the use, plays firm keeping and limiting displacement to elastic terminal.
