Description

Technical Field

[0001] This utility model relates to the field of connection cable technology, specifically to a video connection cable for an image display. Background Technology

[0002] The image display connection cable is a connection cable that connects the medical endoscope image processor and the video endotracheal intubation endoscope. It is a connection cable consisting of a connector head, a male connector, and a connecting wire.

[0003] Currently, most image processors for medical endoscopes on the market lack a sealed structure. This can lead to gaps in the cable during sterilization, affecting image output, resulting in unclear image display, vertical stripes in signal transmission, and ultimately impacting product lifespan. Therefore, our company is developing a waterproof and stable video connection cable for image displays to improve product lifespan and performance. Utility Model Content

[0004] This invention aims to solve the above-mentioned technical problems by providing a video connection cable for an image display.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A video connection cable for an image display includes a shielded cable, one end of which is fitted with a connector for connecting to a video endotracheal endoscope, and the other end of which is fitted with a plug for connecting to a medical endoscope image processor.

[0007] The connector includes a plug sheath and a plug back cover that connects to the plug sheath. The other end of the plug back cover is connected to a detachable plug outer shell. An insulator is installed inside the plug outer shell. Soldering pins are installed on both sides of the insulator. The shielding wire passes through the plug sheath and the plug back cover and is connected to the soldering pins. A locking cover is movably installed on the outside of the plug outer shell. Sealing rings are installed between the locking cover and the plug back cover and the plug outer shell.

[0008] Preferably, the plug housing and the plug rear housing are threaded together.

[0009] Preferably, a pressure ring is installed between the plug housing and the insulator.

[0010] Preferably, an L-shaped baffle is installed on the outer side of the plug housing, and a baffle is installed on one side of the locking cover, forming a sealing area between the L-shaped baffle and the baffle.

[0011] Preferably, a sealing groove is formed on the side of the plug rear shell near the baffle, and two sealing rings are installed in the sealing area and the sealing groove.

[0012] Preferably, a plug tail cap is threadedly connected to the side of the plug rear shell near the plug sheath.

[0013] Preferably, a cable clamp is installed inside the plug end cap and plug sheath.

[0014] Preferably, a sealing ring is installed between the cable clamp and the plug sheath.

[0015] With the above structure, this utility model has the following advantages:

[0016] The connector of this invention features a plug housing that achieves a sealing effect through an L-shaped baffle and a sealing ring within the baffle, which in turn seals the sealing ring within the sealing groove. When the plug housing rotates within the plug rear housing, it causes the L-shaped baffle to approach the locking cover and the plug rear housing, completing the seal through the two sealing rings. This protects the internal circuitry from liquid ingress, ensuring signal transmission is not affected. It also protects the internal solder joints. Furthermore, when connecting the image display cable to the video endotracheal intubation endoscope, only the locking cover needs to be rotated; the connecting cable does not need to be rotated, thus protecting the connection.

[0017] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.
