[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] A side-entry, foolproof shielded interface, such as Figure 1As shown, the interface includes a main body 1, which is usually rectangular in structure and is installed on the side of a circuit board or circuit board for connecting cables of external devices to realize signal transmission and communication of the circuit board. One end of the main body 1 is provided with a connector socket 11, and the connector socket 11 is provided with a foolproof slot 12. Fixing grooves 17 are provided on both sides of the main body 1, and a locking block 13 is fastened to the fixing groove 17. A shielding shell 2 is fastened inside the fixing groove 17 and is fixed to the locking block 13. The locking block 13 fixes the shielding shell 2.

[0027] like Figures 2-4 As shown, a positioning protrusion 14 is fixedly provided inside the foolproof slot 12. When the foolproof plug on the plug is inserted into the foolproof slot 12, a positioning groove is provided on the foolproof plug. The positioning groove is slidably connected with the positioning protrusion 14. A through groove is provided on the positioning protrusion 14. A rubber plug 15 is fixedly provided in the through groove. The rubber plug 15 is inserted into the positioning protrusion 14 and slidably connected with the positioning groove. If the foolproof plug is inserted into the foolproof slot 12 and after long-term use, the positioning groove and the positioning protrusion 14 are too tightly attracted. At this time, pulling out the rubber plug 15 can reduce the attraction force of the positioning groove. At the same time, a screwdriver can be used to press the positioning groove through the through groove to push the foolproof plug and the plug out of the connector socket 11, providing certainty for the plug to be pulled out.

[0028] A groove 16 is provided below the main body 1, and pins 18 are vertically installed in the groove 16. The number of pins 18 is set according to actual needs. In this embodiment, there are 8 pins 18.

[0029] A mounting post 3 is fixedly provided at the bottom of the main body 1. The mounting post 3 is inserted into a pre-drilled hole on the circuit board or circuit board and fixed by means of glue, welding or other methods. The end of the mounting post 3 is provided with an internal threaded hole 31. When the mounting post 3 is inserted into one side of the circuit board or circuit board, a screw is installed on the other side of the circuit board or circuit board. The screw is threadedly connected to the internal threaded hole 31 to lock the mounting post 3 onto the circuit board or circuit board.

[0030] In this embodiment, by setting a foolproof structure on the interface, such as a foolproof slot 12 and a positioning protrusion 14, the accuracy of the connection between the plug and the interface is ensured, the concept of plug mis-insertion is reduced, the problem of short circuit on the circuit board or circuit board caused by plug reverse insertion is reduced, and the safety of using the side-entry interface is improved.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
