DETAILED DESCRIPTION

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0041] like Figures 1 to 24 As shown, the present invention provides a ground terminal and shielding sheet integrated connector, including a connector metal shell 1, a connector signal terminal 2, a connector terminal fixing part 3, a connector ground terminal 4, and a connector plastic shell 5. The connector signal terminal 2, the connector terminal fixing part 3 and the connector ground terminal 4 are all installed in the connector plastic shell 5. The connector metal shell 1 is sleeved on the connector plastic shell 5. The connector signal terminal 2 and the connector ground terminal 4 are used for data transmission.

[0042] The connector grounding terminal 4 includes a plurality of connector first grounding terminals 41 arranged side by side and a connector second grounding terminal 42 located at the first position grounding terminal. The connector first grounding terminal 41 includes a first limiting portion 411, a first welding portion 412, a first shielding portion 413, a first contact portion 414 and a first assembling portion 415. The first welding portion 412 and the first contact portion 414 are fixedly connected to form a "U"-shaped integral structure. The two "U"-shaped integral structures are respectively fixedly connected to the two ends of the first limiting portion 411 to form an integral structure and are symmetrically arranged. The bottom of the "U"-shaped integral structure protrudes outward to form the first assembling portion 415. The first shielding portion 413 is located at the top of the first limiting portion 411 and is a bent inverted "S"-shaped structure. The second grounding terminal 42 of the connector includes a second limiting portion 421, a second welding portion 422, a second shielding portion 423, a second contact portion 424 and a second assembling portion 425. The second limiting portion 421 has the same structure as the first limiting portion 411, the second welding portion 422 has the same structure as the first welding portion 412, the second contact portion 424 has the same structure as the first contact portion 414, and the connection relationship between the second limiting portion 421, the second welding portion 422, the second shielding portion 423, the second contact portion 424 and the second assembling portion 425 is the same as the connection relationship between the first limiting portion 411 and its corresponding part in the first grounding terminal 41 of the connector. The second shielding portion 423 is a bent structure. Since the bending position of the head of the first shielding portion 413 is lower than the bending position of the root of the second shielding portion 423, after the two grounding terminals are assembled to the connector terminal fixing member 3, the end of the first shielding portion 413 abuts against the root of the second shielding portion 423 and forms a retaining force, making the contact tighter.

[0043] In this embodiment, adjacent first shielding parts 413 are in an inverted "S" shape, so that the bending position of the head of the latter first shielding part 413 is lower than the root bending position of the former first shielding part 413, so that the head and the root of each first shielding part 413 contact each other after assembly and form a retaining force, making the contact tighter.

[0044] The first welding portion 412 is connected to the PCB board 6, and the portion where the first welding portion 412 is connected to the PCB board 6 is a rounded structure. The end bending portion of the first contact portion 414 is a rounded structure. The second contact portion 424 has the same structure as the first contact portion 414. It is convenient for the first welding portion 412, the first contact portion 414 to have good contact with other devices, and effectively prevents the burrs that may be generated on the grounding terminal from causing poor contact with other devices after assembly, affecting signal transmission. In this embodiment, the first welding portion 412 and the second welding portion 422 are welded and connected to the PCB board 6, and the rounded structure set thereon makes it easier to stick the melted solder when welding with the PCB, and absorb more solder, thereby ensuring welding stability.

[0045] After the first assembly part 415 and the second assembly part 425 are assembled, they are inserted into the fixing member through slot 311 and have an interference fit with the abutting part in the fixing member through slot 311. Thus, the connection between the connector ground terminal 4 and the connector terminal fixing member 3 is more stable and will not loosen.

[0046] There is an unperforated protruding portion next to the fixing slot 311, so that a groove is formed in the assembled connector terminal fixing 3, which corresponds to the position of each grounding terminal 4. When the grounding terminal 4 is assembled into the connector terminal fixing 3, the first limiting portion 411 and the second limiting portion 421 cooperate with the groove formed in the connector terminal fixing 3, thereby limiting the assembly position of the grounding terminal 4 and preventing the grounding terminal 4 from being damaged by over-insertion.

[0047] In actual use, the number of the first grounding terminals 41 of the connector is multiple and they are arranged in parallel, and the end of the first shielding portion 413 of the adjacent first grounding terminal 41 of the connector abuts against the root of the first shielding portion 413 of the next first grounding terminal 41 of the connector. The first shielding portion 413 located at the end abuts against the root of the second shielding portion 423 of the second grounding terminal 42 of the connector. When in use, the first grounding terminal 41 of the connector and the second grounding terminal 42 of the connector are respectively arranged in the connector terminal fixing member 3. The present invention adopts a method of connecting multiple first grounding terminals 41 of the connector and the second grounding terminal 42 of the connector in series, and the connector grounding terminal 4 has both grounding and shielding functions, so that the series connection has a shielding effect, realizes high-speed transmission of signals in the connector, and reduces crosstalk during high-speed transmission of signals. At the same time, there is no need to make a separate shielding sheet, which reduces the mold cost, its own cost and assembly cost of the product.

[0048] like Figure 13 to Figure 14 As shown, the connector terminal fixing part 3 is a rectangular parallelepiped structure, with a fixing part through slot 311 on the top, and the connector signal terminal 2 is passed through and fixedly connected between adjacent fixing part through slots 311, and the inner side of the connector terminal fixing part 3 is provided with a fixing part protrusion 312 and a fixing part circular hole 314, the fixing part protrusion 312 is a cylindrical structure, and the fixing part circular hole 314 is a groove structure. The outer side of the connector terminal fixing part 3 protrudes outward to form a fixing part second protrusion 313, and the cross section of the fixing part protrusion 313 is a trapezoid.

[0049] The two connector terminal fixing members 3 are connected to form a central symmetrical structure, and the two connector terminal fixing members 3 can be located in the fixing member circular hole 314 of the other one through the end of the fixing member protrusion 312 of one. The two sides of the connector grounding terminal 4 are respectively penetrated through the two assembled fixing member through grooves 311. The fixing member second protrusions 313 on the two connector terminal fixing members 3 are clamped with the connector plastic shell 5.

[0050] In actual use, when two connector terminal fixing members 3 are connected, the first contact portion 414 and the second contact portion 424 are respectively inserted into the two fixing member through grooves 311 .

[0051] The number of the fixing member through slots 311 is twice the total number of the connector first grounding terminals 41 and the connector second grounding terminals 42. The cross section of the fixing member through slots 311 is "L" shaped.

[0052] The number of fixing protrusions 312 and fixing circular holes 314 is equal and multiple and parallel to each other. The inner diameter of the fixing circular hole 314 is slightly larger than the outer diameter of the fixing protrusion 312, so that the fixing protrusion 312 can be located in the fixing circular hole 314. Due to the centrally symmetrical structure of the connector terminal fixings 3, the two connector terminal fixings 3 can be connected.

[0053] like Fig.15 and Fig.16 As shown, the connector plastic shell 5 is a rectangular parallelepiped structure, a connector plastic shell through slot 51 is provided on the top of the connector plastic shell 5, and the connector terminal fixing member 3 is located in the connector plastic shell through slot 51. Connector plastic shell connecting slots 52 are respectively provided on the sides of the connector plastic shell 5, and the ends of the second protrusions 313 of the fixing member extend into the two connector plastic shell connecting slots 52 and are clamped and fixed, and a connector plastic shell fixing column 53 is provided at the bottom of the connector plastic shell 5, and the connector plastic shell 5 is positioned on the PCB board 6 through the connector plastic shell fixing column 53.

[0054] A connector plastic shell protrusion 54 is provided inside the connector plastic shell 5. The connector plastic shell protrusion 54 is a rectangular parallelepiped structure. Two connector terminal fixing members 3 are connected to form a groove in the middle. The connector plastic shell protrusion 54 is located in the groove formed after assembly, which plays a role in rough positioning during assembly.

[0055] In actual use, the end of the connector plastic shell through slot 51 of the present application can be connected to an existing external matching card 7 or a gold finger cable connector. The end of the matching card 7 or the end of the gold finger cable connector is inserted into the connector plastic shell 5 from the open end of the connector plastic shell through slot 51, and contacts the first contact portion 414 and the second contact portion 424 of the signal terminal 2 and the ground terminal 3.

[0056] like Figure 19 to Figure 24As shown, the first grounding terminal 41 of the connector and the second grounding terminal 42 of the connector are made by stamping process, and adopt the form of double material strips, so that two products can be stamped out at one time, which increases the production capacity of the product and reduces the loss of raw materials. The first grounding terminal 41 of the connector and the second grounding terminal 42 of the connector are respectively installed on the metal material strip, and the part where the first grounding terminal 41 of the connector and the second grounding terminal 42 of the connector are connected to the metal material strip is made into a V-shaped groove pre-cut on both the front and back sides, as shown in FIG. Fig.24 As shown, the first grounding terminal 41 of the connector and the second grounding terminal 42 of the connector are removed from the material strip for convenience in subsequent assembly. The rounded corner structure provided on the first contact portion 414 and the second contact portion 424 can effectively prevent burrs and other undesirable conditions generated by the stamping process during the manufacturing process. At the same time, when contacting with the matching card 7 or the gold finger connector after assembly, there is no foreign matter to interfere with signal transmission. The front and back sides of the bottom surfaces of the first welding portion 412 and the second welding portion 422 are both provided with rounded corner structures, so that when welding with the PCB board 6, it is easier to stick the melted solder and absorb more solder to ensure the stability of welding.
