[0021] like Figure 1-7 As shown, the present invention provides an insertion end for a connector, comprising: Mounting body 100 and first terminal group 201 and second terminal group 202; wherein, mounting body 100 is made of 30% glass fiber reinforced material; mounting platform 300 is disposed inside mounting body 100 and divides the interior of mounting body 100 into first mounting space 301 and second mounting space 302; first terminal group 201 and second terminal group 202 are respectively disposed in first mounting space 301 and second mounting space 302; external devices are connected through first terminal group 201 and second terminal group 202, and when the PCB board is inserted into first terminal group 201 and second terminal group 202, the external device and the PCB board are connected; in this utility model, first terminal group 201 and second terminal group 202 are both made of C17200 copper alloy, and a gold plating layer of not less than 1μm is also provided on the contact position of first terminal group 201 and second terminal group 202 with PCB board; An air groove is provided on the mounting platform 300, and the first terminal group 201 and the second terminal group 202 are placed on both sides of the air groove; a shielding plate 500 is also provided in the air groove; on the one hand, the mounting platform 300 divides the interior of the mounting body 100 into the first mounting space 301 and the second mounting space 302; on the other hand, the shielding plate 500 is installed on the mounting platform 300; through the cooperation of the mounting platform 300 and the shielding plate 500, the signal during data transmission between the first terminal group 201 and the second terminal group 202 and the PCB board can be blocked; thereby, the crosstalk between the first terminal group 201 and the second terminal group 202 and the PCB board can be effectively reduced, and the stability of data transmission is improved; in this utility model, the shielding plate 500 is a copper alloy shielding plate 500; and a protective layer is provided on the outer surface of the shielding plate 500, preferably, the protective layer is a nickel plating layer with a thickness of not less than 5μm.
[0022] The technical solution of this utility model divides the mounting body 100 into a first mounting space 301 and a second mounting space 302 through the mounting platform 300 on the mounting body 100. A first terminal group 201 and a second terminal group 202 are respectively arranged in the first mounting space 301 and the second mounting space 302. The first terminal group 201 and the second terminal group 202 are used to connect with external devices. In use, the PCB board is inserted into the first mounting space 301 and the second mounting space 302 respectively, and contacts the first terminal group 201 and the second terminal group 202 within the first mounting space 301 and the second mounting space 302, thus establishing communication between the first terminal group 201 and the second terminal group 202 and the PCB board. During data transmission, a shielding plate 500 placed in an air cavity blocks data transmission between the PCB boards, preventing crosstalk. Simultaneously, the air cavity reduces the dielectric constant, further reducing crosstalk. Compared with the prior art, the technical solution of this utility model effectively blocks crosstalk between PCB boards during data transmission, providing stability for data transmission.
[0023] like Figure 3-5 As shown, the first buckle 601 and the second buckle 602 are disposed opposite to each other at both ends of the mounting body 100; after the PCB board is inserted into the first mounting space 301 and the second mounting space 302, the first buckle 601 and the second buckle 602 simultaneously clamp the two ends of the PCB board, thereby ensuring the stability of the PCB board after it is inserted into the first mounting space 301 and the second mounting space 302. In addition, the mounting body 100 is provided with a first slot and a second slot at both ends, and a first buckle 601 and a second buckle 602 are respectively disposed in the first slot and the second slot. The first slot and the second slot can fix the first buckle 601 and the second buckle 602, thereby ensuring the stability of the first buckle 601 and the second buckle 602. This ensures the stability of the PCB board when clamping it later. Specifically, a first limiting platform and a second limiting platform are respectively disposed in the first slot and the second slot. A first mounting port 603 and a second mounting port are respectively disposed on the first buckle 601 and the second buckle 602. The first mounting port 603 is adapted to the first limiting platform, and the second mounting port is adapted to the second limiting platform. In addition, both the first buckle 601 and the second buckle 602 are provided with protruding plates 605; such as Figure 4 and Figure 5 As shown, after the PCB board is inserted, the protruding plate 605 limits the PCB board to ensure that the PCB board will wobble. The first latch 601 is inserted into the first slot, and the first mounting port 603 is engaged with the first limiting platform. Thus, the first limiting platform limits the first latch 601, and the two ends of the first latch 601 are limited by the sides of the first slot. Figure 7 As shown, after the PCB board is inserted, it will contact the first buckle 601. The PCB board and the first buckle 601 will contact each other and thus squeeze each other, which will increase the connection strength between the first buckle 601 and the PCB board. It should be noted that the connection and fixing method between the second buckle 602, the second slot, the second mounting port, the second limiting stage and the PCB board is the same as the connection and fixing method between the first buckle 601, the first slot, the first mounting port 603, the first limiting stage and the PCB board. For the sake of space, this utility model will not be described further.
[0024] In practical use, after connecting to external devices via the first terminal group 201 and the second terminal group 202, to ensure the stability of the first terminal group 201 and the second terminal group 202 after external connection, a first mounting arm 701 and a second mounting arm 702 are respectively provided at both ends of the mounting body 100. The first mounting arm 701 is provided with a first mounting hole 703, and the second mounting arm 702 is provided with a second mounting hole 704. In practical use, the connection to external devices is achieved by passing bolts through the first mounting hole 703 and the second mounting hole 704, thereby ensuring the stability of the connection between the first terminal group 201 and the second terminal group 202 and the external devices.
[0025] In addition, in this utility model, the diameter of the first mounting hole 703 is larger than the diameter of the second mounting hole 704; thus, when installing with external equipment, the first mounting hole 703 and the second mounting hole 704 can be used to determine whether the installation direction is correct, avoiding misoperation that could damage the first terminal group 201 and the second terminal group 202.
[0026] like Figure 6 As shown, a first mounting plate 303 is provided in the first mounting space 301, and a second mounting plate 304 is provided in the second mounting space 302; a first terminal group 201 is provided on the first mounting plate 303, and a second terminal group 202 is provided on the second mounting plate 304; the first mounting plate 303 and the second mounting plate 304 provide support for the interior of the first terminal group 201 and the second terminal group 202 to prevent deformation during extreme use and affect the connection effect.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
