- the coaxial cable at a predetermined position is fitted into the mold, and the material constituting the holding material 20 in the mold is in a liquid state, while the outermost layer AO of the coaxial cable melts and the holding material
- the material constituting the material 20 is poured in a liquid state so as to be compatible with the material constituting the outermost layer AO, and then cooled to join the holding material 20 to the coaxial cable.
- the holding material and each coaxial cable are fused, and the holding elements keep the coaxial cables arranged in a horizontal row so that the gap between the coaxial cables can be obtained even during use. Since it is possible to prevent cuts in the portions, it is possible to set each coaxial cable to an appropriate length, thereby preventing, for example, tangling of the coaxial cables.
- the holding material 20 that holds the eight coaxial cables A12 to A82 has been described.
- the present invention is not limited to this, and for example, as shown in FIG. 21, the adjacent coaxial cables, in this embodiment, the coaxial cables A12, A 32, A52 and A22, A42, A62 are held in a line in a row, and the gap between the coaxial cables is held. It is also possible to prevent the occurrence of breaks in the Can be held in detail, and each coaxial cable can be set to an optimum length. Also, in the case of this drip-proof holding member, as in the case of the above-mentioned connection portion cover and outermost layer, the adhesion to the outermost layer can be improved by thermocompression bonding or processing that applies external force. Of course, what you can do is possible.
- the antenna and the coaxial cable can be seamlessly covered with the connection portion cover and the outermost layer, so that the disinfection solution can be sprayed by spraying, for example.
- the connection portion cover and the outermost layer so that the disinfection solution can be sprayed by spraying, for example.
- the force described in the case of the antenna unit is not limited to this, and any application can be applied as long as a coaxial cable is used.
- a coaxial cable is connected to a device that requires drip-proofing
- the connecting part of the device and the coaxial cable for example, a connector and a coaxial cable are formed in the same way as in the example, the drip-proofing property will be the same.
- the present invention can naturally be applied to the case of a single cable.
- the antenna unit and the method for manufacturing the antenna unit according to the present invention are useful for a medical observation apparatus that is introduced into a human body and observes a region to be examined. This is suitable for preventing moisture from entering the gaps between the antenna and the coaxial cable and the connection part and improving the drip-proof property.
