Description

Technical Field

[0001] The present invention relates to the technical field of medical active device interfaces, and particularly to an anti-misconnection interface for medical active devices. Background Art

[0002] Medical active devices achieve therapeutic purposes through application parts and signal parts. These application parts or signal parts usually have one or more external cable interfaces. The basic function of the interfaces is to connect external therapeutic accessories or signal acquisition accessories through pluggable cables. The main feature of the interfaces is to ensure a reliable electrical connection between the medical active devices and the external accessories, and the connected accessories can be inserted or removed as needed to ensure the realization of therapeutic and diagnostic functions, and to ensure the ease of use and maintenance convenience of the devices; When a medical active device has multiple interfaces, it must be able to prevent incorrect connections. Once an incorrect connection occurs, it may cause medical accidents and seriously endanger the life and health of patients; Existing medical active devices usually use connectors of different models and specifications for interfaces with different functions to avoid incorrect connections. The use of interfaces with different models and specifications in existing medical active devices makes the structure of medical devices relatively complex. The installation processes of interfaces with different models and specifications may be different, which not only makes the installation process complex but also increases the procurement and deployment difficulties of interface accessories; In view of the above problems, the inventor proposes an anti-misconnection interface for medical active devices to solve the above problems. Summary of the Invention

[0003] In order to solve the above problems, the purpose of the present invention is to provide an anti-misconnection interface for medical active devices.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: An anti-misconnection interface for medical active devices includes a socket and a plug. The socket is integrally formed. The plug is composed of an upper cover and a lower cover. A 6-core card seat or a 4-core card seat can be installed at the rear of the socket. There are three fixing holes at the rear of the socket 1, and the fixing holes are used to fix and weld the PCB board with the card seat. The 6-core card seat is installed horizontally, and the 4-core card seat is installed vertically; There is a cross plate inside the plug. There are a second horizontal opening and a second vertical opening on the cross plate. There are a horizontal limiting strip and a vertical limiting strip inside the plug. There are a horizontal blocking rib and a vertical blocking rib inside the plug; A 6-core PCB connector board or a 4-core PCB connector board can be installed inside the plug. The 6-core PCB connector board is horizontally installed through the cross plate, the second horizontal opening, the horizontal limiting strip and the horizontal blocking rib.

[0006] Preferably, there is a cross baffle inside the socket. The cross baffle is formed by a first horizontal opening and a first vertical opening to form a cross opening. The first horizontal opening allows the 6-core PCB connector board in the plug to pass through, and the first vertical opening allows the 4-core PCB connector board in the plug to pass through.

[0007] Preferably, the cross baffle inside the socket is fixed inside the socket through the connecting ribs on both sides. There are side grooves on both sides of the front part of the plug, and the side grooves are used to avoid the connecting ribs on both sides of the cross baffle inside the socket.

[0008] Preferably, there is a small card slot at the upper end inside the socket, and there is a small tenon at the upper end of the plug, and the small tenon is movably clamped with the small card slot.

[0009] Preferably, there are two elastic tenons for installation on the outside of the socket.

[0010] Preferably, there are upper cover connecting columns in the upper cover of the plug, and there are lower cover connecting holes in the lower cover of the plug. There is an upper protrusion on the socket at the upper end of the front opening of the socket, and there is an upper protrusion on the upper cover of the plug.

[0011] Preferably, there is a small card slot in the middle of the upper protrusion of the socket.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment: As Figure 1-6 shown, the present invention provides an anti-misconnection interface for a medical active device, including a socket 1 and a plug 2. The socket 1 is integrally formed. The rear part of the socket 1 is inside the chassis, and the front part of the socket 1 leads to the outside of the chassis (refer to Figure 2 and Figure 6 ). Two different PCB board card holders with 6 cores or 4 cores can be installed at the rear part of the socket 1 (refer to Figure 3 , Figure 4 ). Among them, the 6-core card holder 1-6 is installed horizontally, and the 4-core card holder 1-4 is installed vertically, thus becoming a 6-core socket or a 4-core socket. There are three fixing holes 1-3 at the rear part of the socket 1 for fixing the PCB board welded with the card holder (refer to Figure 2 , Figure 4 ). The PCB board (not shown) can be designed to be welded with the 6-core card holder 1-6 or the 4-core card holder 1-4 to meet different interface requirements. The 6-core card holder 1-6 on the PCB board (not shown) is welded horizontally, and the 4-core card holder 1-4 is welded vertically. The PCB board (not shown) where the 6-core card holder 1-6 or the 4-core card holder 1-4 is located is assembled at the rear part of the socket 1 through three fixing holes 1-3, so that the 6-core card holder 1-6 or the 4-core card holder 1-4 is assembled at the rear part of the socket 1. After assembling the 4-core card holder 1-4, it becomes a 4-core socket, and after assembling the 6-core card holder 1-6, it becomes a 6-core socket; The front part of the socket 1 can insert the plug 2. The plug 2 is composed of an upper cover 2A and a lower cover 2B. There is a cross plate 2-10 inside the plug 2. There are a second horizontal opening 2-16 and a second vertical opening 2-14 on the cross plate 2-10. There are a horizontal limiting strip 2-20 and a vertical limiting strip 2-15 inside the plug 2. There are a horizontal blocking rib 2-19 and a vertical blocking rib 2-17 inside the plug 2. Two different PCB connector boards with 6 cores or 4 cores can be installed inside the plug 2. Among them, the 6-core PCB connector board 2-6 is horizontally installed 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, and the 4-core PCB connector board 2-4 is vertically installed 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 4-core connector board 2-4, it becomes a 4-core plug, and after assembling the 6-core connector board 2-6, it becomes a 6-core plug (refer to Figure 5 ).

[0023] Inside the socket 1, there is a cross baffle 1-10. In the middle of the cross baffle 1-10, a cross opening is formed by a first horizontal opening 1-16 and a first vertical opening 1-14. The first horizontal opening 1-16 allows the 6-core PCB connector board 2-6 in the plug 2 to pass through, and the first vertical opening 1-14 allows the 4-core PCB connector board 2-4 in the plug 2 to pass through. When a 4-core plug attempts to be inserted into a 6-core socket, the longitudinal 4-core connector board 2-4 of the plug 2 is blocked by the horizontally placed 6-core socket holder 1-6 in the socket and cannot be inserted. Similarly, when a 6-core plug attempts to be inserted into a 4-core socket, the horizontal 6-core connector board 2-6 of the plug 2 is blocked by the vertically placed 4-core socket holder 1-4 in the socket and cannot be inserted, which has the function of preventing misconnection.

[0024] The internal cross baffle 1-10 of the socket 1 is fixed inside the socket 1 through the connecting ribs 1-11 on both sides thereof. On both sides of the front part of the plug 2, there are side slots 2-12, and the side slots 2-12 can avoid the connecting ribs 1-11 on both sides of the cross baffle 1-10 inside the socket 2, enabling the plug 2 to be inserted into the socket 1.

[0025] At the upper end inside the socket 1, there is a small card slot 1-1, and at the upper end of the plug 2, there is a small tenon 2-1. When the plug 2 is inserted into the socket 1, the small tenon 2-1 at the upper end of the plug 2 enters the small card slot 1-1 at the upper end inside the socket 1, playing a self-locking function between the plug 2 and the socket 1, which can prevent the plug 2 from falling off and make the connection firm and reliable.

[0026] On the outside of the socket 1, there are two elastic tenons 1-15 for installation. When the socket 1 is installed on a medical active device, as long as the socket 1 is pressed into the corresponding installation hole on the device, the elastic tenons 1-15 will automatically lock, ensuring that the socket 1 is firmly installed on the medical active device.

[0027] At the rear part of the plug 2, there is an SR slot 2-21, which can be assembled with an SR head to avoid excessive bending of the cable to protect the cable.

[0028] In the upper cover 2A of the plug 2, there are upper cover connection posts 2-23, and in the lower cover 2B of the plug 2, there are lower cover connection holes 2-22. When the upper cover 2A and the lower cover 2B are buckled, screws are screwed into the lower cover connection holes 2-22 and the upper cover connection posts 2-23 to fix the upper cover 2A and the lower cover 2B to form the plug 2.

[0029] At the upper end of the front opening of the socket 1, there is an upper socket protrusion 1-24, and at the upper part of the upper cover 2A of the plug 2, there is an upper plug protrusion 2-24 (refer to Figure 6 ) When the plug 2 is inserted into the socket 1, the upper plug protrusion 2-24 is aligned with the upper socket protrusion 1-24 to be correctly inserted, preventing the plug 2 from being inserted in the wrong direction.

[0030] There is a small card slot 1-25 in the middle of the upper protrusion 1-24 of the socket 1. When the plug 2 is inserted into the socket 1, the small tenon 2-1 on the upper part of the plug can pass through the small card slot 1-25 to ensure that the plug 2 smoothly enters the socket 1.

[0031] Working principle: The socket 1 and the plug 2 body of this application are both made of ABS injection molded parts. After the socket 1 is assembled with a 4-core card seat 1-4 and a 6-core card seat 1-6, it becomes a 4-core or 6-core socket. After the plug 2 is assembled with a 4-core PCB connector board 2-4 and a 6-core PCB connector board 2-6, it becomes a 4-core or 6-core plug. This application adopts a mutually perpendicular installation method in which the 4-core card seat 1-4 is longitudinally installed in the socket 1, the 4-core connector board 2-4 is longitudinally installed in the plug 2, the 6-core card seat 1-6 is horizontally installed in the socket 1, and the 6-core PCB connector board 2-6 is horizontally installed in the plug 2, realizing the anti-misinsertion function that different core wires cannot be misinserted with each other. In this application, since the 4-core card seat 1-4 and the 4-core PCB connector board 2-4 are respectively arranged longitudinally in the socket 1 and the plug 2, an upper protrusion 1-24 of the socket is formed in the socket 1, and an upper protrusion 2-24 of the plug is formed in the plug 2. When the plug 2 is inserted into the socket 1, only when the upper protrusion 2-24 of the plug is aligned with the upper protrusion 1-24 of the socket can it be correctly inserted, realizing the anti-misinsertion function that the plug 2 cannot be misinserted when the direction is incorrect.

[0032] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and its equivalent technologies, the present invention is also intended to include these modifications and variations.
