Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic connection devices, and in particular to a connector that prevents mis-insertion. Background Technology
[0002] In a modern medical environment, a successful surgery requires the coordination of multiple devices. For example, the anesthesia machine, a key device for maintaining the patient's vital signs during surgery, needs to work with various monitoring instruments and exchange data. Currently, these devices are mostly connected via a standard USB interface.
[0003] Existing USB connectors and interfaces require distinguishing between the correct and incorrect orientations, which can easily lead to mis-insertion in emergency situations. Furthermore, operating rooms contain numerous devices that connect using standard USB interfaces without proper labeling, increasing the risk of connection errors.
[0004] In addition, USB connectors require at least 25mm of straight insertion space, but the available space on the connector panel of some surgical equipment is less than 25mm, and the available space on the side of anesthesia machines is usually less than 20mm, making it difficult to insert USB connectors. Even if they are forced to insert, the USB connector cable needs to be bent to accommodate the stress, which concentrates at the bend and makes it easy to break, reducing its service life.

[0034] This utility model provides a mis-plugging prevention connector that plugs into a device's interface panel, such as... Figure 1 and Figure 2 As shown, the anti-misplug connector includes a plug body 1, a wiring portion 2, and a cable 3. The wiring portion 2 is disposed on the plug body 1, and the cable 3 is inserted into and passes through the wiring portion 2 to connect with the plug body 1.
[0035] Combination Figure 3As shown, the plug body 1 includes a connector portion 11, a plug middle portion 12, a fixing wing 13, a positioning protrusion 14, and a plug tail portion 15. The plug middle portion 12 connects the connector portion 11 and the plug tail portion 15, and is located between the connector portion 11 and the plug tail portion 15. The fixing wing 13 is disposed on the outer side wall 121 of the plug middle portion 12. The positioning protrusion 14 is disposed on the surface of the plug body 1 that contacts the plug panel (not shown in the figure), and cooperates with the positioning groove on the surface of the plug panel to achieve plug positioning and prevent the connector from being mis-inserted when there are multiple different plug panels.
[0036] like Figure 2 As shown, the connector portion 11 is provided with a connector terminal 111 and a connector opening 112. The connector terminal 111 is located inside the connector portion 11 and is connected to the cable 3. The connector opening 112 is located at one end of the connector portion 11 away from the middle part 12 of the plug and exposes the connector terminal 111.
[0037] Combination Figure 3 As shown, the fixed wing 13 includes a left fixed wing 131 and a right fixed wing 132, which are located on the left and right sides of the middle portion 12 of the plug, respectively. The positioning protrusion 14 is disposed on one of the left fixed wing 131 or the right fixed wing 132. In a preferred embodiment of the present invention, the positioning protrusion 14 is disposed on the left fixed wing 131. In a preferred embodiment of the present invention, the positioning protrusion 14 is an asymmetrical trapezoid with a height of 4.2 mm, forming a unique matching relationship with the positioning groove of the plug panel.
[0038] like Figure 2 As shown, a left fixing hole 133 is provided at the end of the left fixing wing 131 away from the center 12 of the plug, and a right fixing hole 133 is provided at the end of the right fixing wing 132 away from the center 12 of the plug. The left fixing hole 133 and the right fixing hole 134 cooperate with the corresponding screws on the plug panel to fix the anti-misinsertion connector of this utility model on the plug panel. The distance from the center of the left fixing hole 133 to the central axis L of the plug body 1 is different from the distance from the center of the right fixing hole 134 to the central axis L of the plug body, thereby preventing the anti-misinsertion connector from being upside down during insertion and reducing the risk of misinsertion.
[0039] In a preferred embodiment of this utility model, the distance from the center of the left fixing hole 133 to the central axis L of the connector body is 24.85 mm, and the distance from the center of the right fixing hole 134 to the central axis L of the connector body is 22.85 mm, but not limited thereto.
[0040] Preferably, a fixing nut 135 is provided in the left fixing hole 133 and the right fixing hole 134 through an interference fit. The fixing nut 135 can cooperate with the corresponding screw on the plug panel to fix the anti-misinsertion connector of this utility model on the plug panel. In the preferred embodiment of this utility model, the fixing nut 135 is a 304 stainless steel hexagonal nut, but it is not limited thereto.
[0041] Combination Figure 4 As shown, the wiring portion 2 is located on the upper or lower surface of the plug tail 15 of the plug body 1, and the interior of the wiring portion 2 communicates with the interior of the plug body 1. One end of the wiring portion 2 connected to the plug tail 15 is a wiring connection end 21, and the other end is provided with a wiring opening 22. The cable 3 is inserted into the wiring portion 2 through the wiring opening 22. The wire in the cable 3 passes through the wiring portion 2 into the plug body 1 and connects to the plug terminal 111. Figure 3 As shown, preferably, the wiring opening 22 faces the side of the plug body 1, and the insertion direction A of the connector portion 11 is perpendicular to the extension direction B of the cable. This ensures that the cable routing is parallel to the surface of the connector panel, solving the problem of difficult wiring in confined spaces. It also reduces the cable bending radius to ≥5 times the wire diameter, avoiding exceeding the minimum bending radius specified in the UL758 standard.
[0042] In a preferred embodiment of the present invention, the wiring part 2 is disposed on the lower surface of the plug tail. Therefore, after the cable 3 is inserted into the wiring part 2, the wire in the cable 3 bends upward at 90° at the wiring connection end 21 and enters the plug tail 15 of the plug body 1. Then, at the plug tail 15, it bends 90° toward the plug connector 11, passes through the middle part 12 of the plug, enters the plug connector 11, and connects with the plug terminal 111.
[0043] When using the anti-misinsertion plug of this utility model, the corresponding plug panel is first identified by the positioning protrusion 14, and the front and back sides are distinguished by the different distances from the left fixing hole 133 and the right fixing hole 134 on the fixing wing 13 to the central axis L.
[0044] The advantages of this utility model are:
[0045] 1. The anti-misfit connector of this utility model has a positioning protrusion 14 that is uniquely matched with the positioning groove of the connector panel, so that the operator can quickly identify the connector that is matched with the connector panel and prevent the connector from being matched with the wrong connector panel.
[0046] 2. The present invention uses a design where the distances from the left fixing hole 133 and the right fixing hole 134 to the central axis L of the connector portion 11 are different, so that the operator can quickly determine the front and back of the connector and the connector panel, and prevent the connector from being incorrectly fixed on the connector panel.
[0047] 3. By designing the wiring part 2, the wires in the cable 3 are connected to the plug terminal 111 after two 90° bends, so that the extension direction of the cable 3 is perpendicular to the insertion direction of the plug part 11. In this way, the extension direction of the cable 3 is parallel to the plug panel, saving plug space, solving the problem of difficult wiring in narrow spaces, reducing the time for medical staff to adjust the cable, and avoiding stress concentration caused by right-angle bends of the exposed cable 3, reducing the risk of cable 3 breakage and extending service life.
