[0040] Please refer to Figures 1 to 7 As shown, it shows the specific structure of the first preferred embodiment of the utility model, including an insulating body 10, a terminal set 20 and a shielding shell 30.

[0041] The rear end of the insulating body 10 has a positioning groove 101 for positioning the cable 40. Specifically, the insulating body 10 includes a main body 11 and a rear seat 12. The main body 11 includes a base 111 and a tongue plate 112 extending forward from the base 111. The rear seat 12 is arranged behind the base 111 and fixedly connected to the base 111. The positioning groove 101 is located on the rear seat 12, and support platforms 121 are provided on both sides of the positioning groove 101. The bottom surface of the positioning groove 101 is concavely provided with a plurality of left-and-right spaced-apart making way grooves 122, and each of the making way grooves 122 extends forward and backward.

[0042] The terminal group 20 is arranged on the insulating body 10, and the terminal group 20 has a plurality of contact portions 21, and the plurality of contact portions 21 are exposed on the upper and lower surfaces of the tongue plate 112 of the insulating body 10, and the terminal group 20 has a plurality of connecting pins 22, and the plurality of connecting pins 22 are arranged side by side and spaced in the positioning groove 101, and the plurality of connecting pins 22 are respectively connected with the corresponding contact portions 21 for data and current conversion. In this embodiment, the terminal group 20 and the main body 11 are fixed together by inlay molding, and the plurality of connecting pins 22 extend backward from the rear end surface of the base 111, and the plurality of connecting pins 22 are all in the form of spring sheet structure, so as to be elastically contacted and connected with the solder pad (not shown) on the end of the flat cable 40, and the connection is more stable and reliable. In addition, the plurality of connecting pins 22 are respectively suspended above the corresponding clearance grooves 122, and the clearance grooves 122 provide elastic deformation space for the connecting pins 22.

[0043] The shielding shell 30 is covered on the outside of the insulating body 10, and the front end of the shielding shell 30 has an insertion port 301, and the tongue plate 112 of the insulating body 10 is suspended in the insertion port 301. In this embodiment, both sides of the shielding shell 30 extend outward with fixing feet 302, and each fixing foot 302 is provided with a fixing hole 303, and each fixing hole 303 is provided with a screw 61 for fixing to the circuit board 50, and the screw 61 is screwed and fixed with a nut 62 to facilitate the disassembly and replacement of this product. In addition, a plurality of spring-pressing sheets 304 extend backward from the upper side of the rear end of the shielding shell 30, and the plurality of spring-pressing sheets 304 are arranged at intervals on the left and right. In addition, both sides of the rear end of the shielding shell 30 are bent inward to extend the limiting portion 305. Specifically, the shielding shell 30 includes an inner shell 31 and an outer shell 32; the inner shell 31 is a seamless stretch shell, which is sealed and installed with the main body 11, and the plug port 301 is located in the inner shell 31 to achieve a waterproof function; the outer shell 32 is fitted outside the inner shell 31 and fixedly connected by laser spot welding, and the fixing legs 302 extend outwards on both sides of the outer shell 32, and the bottom surface of the fixing legs 302 is flush with the bottom surface of the inner shell 31, so that the product can be installed on the board, that is, the product is installed and fixed on the surface of the circuit board 50. The multiple spring plates 304 extend backwards from the rear side of the outer shell 32, and the limit portion 305 is bent inwards and extends from both sides of the rear end of the outer shell 32.

[0044] Furthermore, a flip cover 70 that can be turned upside down to press or release the flat cable is provided in the positioning groove 101. When the flip cover 70 presses the flat cable 40, the flat cable 40 is in contact with the plurality of connecting pins 22 for conduction. In this embodiment, the flip cover 70 is hinged between the rear end of the insulating body 10 and the rear end of the shielding shell 30, and has a simple structure and is easy to assemble. Specifically, both ends of the front side of the flip cover 70 extend outward with bosses 71, which are arc-shaped asymmetrical structures. The two bosses 71 are rotatably pressed against the surfaces of the two support platforms 121, and the front side surface of the flip cover 70 is concavely provided with a plurality of hinge holes 72. The plurality of spring-pressing sheets 304 press against the front side surface of the flip cover 70 and extend into the corresponding hinge holes 72 for hinged connection, so as to cause the flip cover 70 to flip downward, so that the flip cover 70 can fix and press the cable 40. The hinge holes 72 can prevent the flip cover 70 from moving forward, and the front side bottom surface of the flip cover 70 extends downward with a pressing portion 73 for pressing the cable 40, so as to better press the cable 40. In addition, the two limiting portions 35 are respectively located behind the two bosses 71 to prevent the flip cover 70 from moving backward, so that the flip cover 70 can be stably installed.

[0045] The method of using this embodiment is described in detail as follows:

[0046] When in use, the product is placed on the surface of the circuit board 50, and then the screw 61 is passed from top to bottom through the fixing hole 303 and the through hole 51 of the circuit board 50 and screwed and fixed with the nut 62, so that the product is firmly fixed on the circuit board 50, and it is very convenient to disassemble. In the original state, the multiple spring-pressing pieces 304 provide elastic force, so that the flip cover 70 maintains the tendency to flip downward. When the cable 40 needs to be installed, the rear end of the flip cover 70 is applied by hand to flip the flip cover 70 upward, and then the end of the cable 40 is embedded in the positioning groove 101, so that each pad at the end of the cable 40 is respectively in contact with the corresponding connection pin 22, and then the flip cover 70 is released. Under the action of the multiple spring-pressing pieces 304, the flip cover 70 automatically flips downward to tightly press the cable 40, so that the cable 40 remains in contact with the multiple connection pins 22.

[0047] When the flat cable 40 needs to be replaced, the rear end of the flip cover 70 is manually applied to flip the flip cover 70 upward, and then the original flat cable 40 is taken out downward from the positioning groove 101, and the end of another flat cable 40 is embedded in the positioning groove 101, so that each pad at the end of the other flat cable 40 is respectively in contact with the corresponding connecting pins 22, and then the flip cover 70 is released. Under the action of the multiple spring-pressing sheets 304, the flip cover 70 automatically flips downward to tightly press the other flat cable 40, so that the other flat cable 40 remains in contact with the multiple connecting pins 22, thereby achieving the replacement of the flat cable 40.

[0048] Please refer to Figure 8 As shown, it shows the specific structure of the second preferred embodiment of the utility model. The specific structure of this embodiment is basically the same as the specific structure of the first preferred embodiment mentioned above, and the difference is that:

[0049] In this embodiment, the bottom surface of the fixing foot 302 is higher than the bottom surface of the inner shell 31, so that the product can be installed in a sunken plate, that is, the product is partially sunken into the notch 52 of the circuit board 50 to save the installation space occupied by the product.

[0050] The method of use of this embodiment is basically the same as the method of use of the first preferred embodiment described above, and the method of use of this embodiment will not be described in detail here.

[0051] The design focus of the utility model is: first, by setting a positioning groove at the rear end of the insulating body, the positioning groove is used to position the flat cable, and a plurality of connecting feet are set in the positioning groove, and a flip cover is set at the same time, which can be turned up and down to press or loosen the flat cable without welding, so that the flat cable can be replaced simply and quickly, which brings convenience to users.
