Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example: Figures 1-6 As shown, the present invention provides a fault-proof interface for a medical active device, including a socket 1 and a plug 2. The socket 1 is integrally formed, with the rear of the socket 1 located inside the chassis and the front of the socket 1 opening to the outside of the chassis (see reference). Figure 2 and Figure 6 The rear of socket 1 can accommodate either a 6-pin or a 4-pin PCB board slot (see reference). Figure 3 , Figure 4 The 6-pin socket 1-6 is installed horizontally, and the 4-pin socket 1-4 is installed vertically, thus forming a 6-pin socket or a 4-pin socket. Socket 1 has three fixing holes 1-3 at the rear for fixing the PCB board with the sockets soldered on (see reference). Figure 2 , Figure 4 The PCB board (not shown) can be designed to solder a 6-pin socket 1-6 or a 4-pin socket 1-4 to adapt to different interface requirements. The 6-pin socket 1-6 on the PCB board (not shown) is soldered horizontally, and the 4-pin socket 1-4 is soldered vertically. The PCB board (not shown) containing the 6-pin socket 1-6 or the 4-pin socket 1-4 is assembled to the rear of the socket 1 through three fixing holes 1-3, so that the 6-pin socket 1-6 or the 4-pin socket 1-4 is assembled to the rear of the socket 1. After assembling the 4-pin socket 1-4, it becomes a 4-pin socket, and after assembling the 6-pin socket 1-6, it becomes a 6-pin socket.

[0033] The front part of the socket 1 can be inserted into the plug 2, which is composed of an upper cover 2A and a lower cover 2B. The plug 2 has a cross plate 2-10 inside, and the cross plate 2-10 has two horizontal openings 2-16 and two vertical openings 2-14. The plug 2 has horizontal limiting strips 2-20 and vertical limiting strips 2-15 inside. The plug 2 has horizontal blocking ribs 2-19 and vertical blocking ribs 2-17 inside. The plug 2 can be installed with two different PCB connector boards, one with six cores and the other with four cores. The six-core PCB connector board 2-6 is installed horizontally through the cross plate 2-10, the second horizontal opening 2-16, the horizontal limiting strip 2-20, and the horizontal blocking rib 2-19. The four-core PCB connector board 2-4 is installed vertically through the cross plate 2-10, the second vertical opening 2-14, the vertical limiting strip 2-15, and the vertical blocking rib 2-17. After assembling the four-core connector board 2-4, it becomes a four-core plug. After assembling the six-core connector board 2-6, it becomes a six-core plug (see Figure 5 ).

[0034] The socket 1 has a cross blocking plate 1-10 inside. The cross blocking plate 1-10 has a cross opening formed by a first horizontal opening 1-16 and a first vertical opening 1-14 in the middle. The first horizontal opening 1-16 allows the six-core PCB connector board 2-6 in the plug 2 to pass through. The first vertical opening 1-14 allows the four-core PCB connector board 2-4 in the plug 2 to pass through. When a four-core plug tries to be inserted into a six-core socket, the vertical four-core connector board 2-4 of the plug 2 is blocked by the horizontally placed six-core holder 1-6 in the socket and cannot be inserted. Similarly, when a six-core plug tries to be inserted into a four-core socket, the horizontal six-core connector board 2-6 of the plug 2 is blocked by the vertically placed four-core holder 1-4 in the socket and cannot be inserted, thus having an error prevention function.

[0035] The internal cross blocking plate 1-10 of the socket 1 is fixed inside the socket 1 through the connecting ribs 1-11 on both sides. The front part of the plug 2 has side slots 2-12 on both sides, which can avoid the connecting ribs 1-11 on both sides of the cross blocking plate 1-10 inside the socket 1, so that the plug 2 can be inserted into the socket 1.

[0036] The inside upper end of the socket 1 has a first small clamping groove 1-1. The upper end of the plug 2 has a small clamping tenon 2-1. When the plug 2 is inserted into the socket 1, the small clamping tenon 2-1 at the upper end of the plug 2 enters the first small clamping groove 1-1 at the upper end inside the socket 1, which serves as a self-locking function of the plug 2 and the socket 1, preventing the plug 2 from falling off and ensuring firm and reliable connection.

[0037] The outside of the socket 1 has two elastic clamping tenons 1-15 for installation. When the socket 1 is installed on a medical active device, as long as the socket 1 is inserted into the corresponding installation hole on the device, the elastic clamping tenon 1-15 will automatically lock, ensuring that the socket 1 is firmly installed on the medical active device.

[0038] The rear part of the plug 2 has an SR slot 2-21, which can be assembled with an SR head to avoid excessive bending of the cable to protect the cable.

[0039] The plug 2 has an upper cover connecting column 2-23 in the upper cover 2A and a lower cover connecting hole 2-22 in the lower cover 2B. When the upper cover 2A is buckled with the lower cover 2B, a screw is screwed into the lower cover connecting hole 2-22 and the upper cover connecting column 2-23 to fix the upper cover 2A and the lower cover 2B to form the plug 2.

[0040] The front part of the socket 1 has a socket upper protrusion 1-24 at the upper end of the hole, and the plug 2 has a plug upper protrusion 2-24 (see Figure 6 When the plug 2 is inserted into the socket 1, the plug upper protrusion 2-24 is aligned with the socket upper protrusion 1-24 to ensure correct insertion and prevent the plug 2 from being inserted in the wrong direction.

[0041] The socket upper protrusion 1-24 of the socket 1 has a small clamping groove 1-25 in the middle. When the plug 2 is inserted into the socket 1, the small clamping tenon 2-1 of the plug can pass through the second small clamping groove 1-25 to ensure that the plug 2 smoothly enters the socket 1.

[0042] Working principle: The socket 1 and the plug 2 of the present application are both made of ABS injection molding parts. After assembling the 4-core clamping seat 1-4 and the 6-core clamping seat 1-6, the socket 1 becomes a 4-core or 6-core socket. After assembling the 4-core PCB connector board 2-4 and the 6-core PCB connector board 2-6, the plug 2 becomes a 4-core or 6-core plug.

[0043] The present application adopts a perpendicular installation method that the 4-core clamping seat 1-4 is installed longitudinally in the socket 1, the 4-core connector board 2-4 is installed longitudinally in the plug 2, the 6-core clamping seat 1-6 is installed transversely in the socket 1, and the 6-core PCB connector board 2-6 is installed transversely in the plug 2, which realizes the mistake-proofing function that different core wires cannot be mistakenly inserted.

[0044] The present application adopts a longitudinal installation method that the 4-core clamping seat 1-4 and the 4-core PCB connector board 2-4 are respectively installed in the socket 1 and the plug 2, which forms the socket upper protrusion 1-24 in the socket 1 and the plug upper protrusion 2-24 in the plug 2. When the plug 2 is inserted into the socket 1, only the plug upper protrusion 2-24 is aligned with the socket upper protrusion 1-24 to ensure correct insertion, which realizes the mistake-proofing function that the plug 2 cannot be mistakenly inserted when the direction is wrong.

[0045] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Therefore, if these modifications and variations of the present application belong to the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
