For example, in the time of will being replaced by new sheath because of the sheath that timeliness changes aged general flexible cord 110, disconnect cables 112, cable 112 is extracted from general flexible cord 110 from operating portion 109 sides from the single line pin 152 and the coaxial pins 154 of electric connector 120.With cable 112 slotting the leading in the sheath of new general flexible cord 110 of extracting, and be connected once more on the single line pin 152 and coaxial pins 154 of electric connector 120.

And, in the time will being replaced by new sheath, disconnect cables 112 from the single line pin 152 and the coaxial pins 154 of electric connector 120 because of the sheath that timeliness changes aged general flexible cord 110.The cable 112 that disconnects from operating portion 1 09 side-linings is also extracted from the sheath of general flexible cord 110, further from the front trailing cable line 112 of insertion section 108 and extract from the sheath of operating portion 109 and insertion section 108.The cable 112 that to extract from operating portion 109 and insertion section 108 is once more inserted and is led in the sheath of new insertion section 108, and then inserts once more and lead in operating portion 109 and general flexible cord 110, is connected once more afterwards on the single line pin 152 and coaxial pins 154 of electric connector 120.

Promptly, the affirmation of the image unit of the fujinon electronic video endoscope 102 that connects via cable 112 on existing electric connector 120 or the confirming operation of Switch, trouble location and changing when repairing needs to be connected cable 112 on the electric connector 120 and cuts off, is connected to the cable 112 that cuts off on the checking tool and once more cable 112 is connected to loaded down with trivial details operation such on the electric connector 120 and more activity duration.And, when changing the sheath of insertion section 108 or general flexible cord 110, also need to cut off, the cable 112 that cuts off is extracted, is inserted into once more the sheath of new insertion section 108 and general flexible cord 110 and once more cable 112 is connected loaded down with trivial details operation on the electric connector 120 and the more activity duration from the sheath of general flexible cord 110 and insertion section 108 with being connected cable 112 on the electric connector 120.

And a plurality of single line pins 152 and the coaxial pins 154 that are arranged on the electric connector 120 are arranged in the limited area, so each single line pin 152 and coaxial pins 154 interval each other are narrower.Single line pin 152 and coaxial pins 154 interval each other are narrow, and be difficult to only cut off the cable 112 that is connected with image unit from single line pin 152 with coaxial pins 154, perhaps be difficult to optionally only cut off the cable 112 that is connected with Switch with coaxial pins 154 from single line pin 152.Therefore, when any confirming operation that carries out image unit or Switch and fault investigation, whole cables 112 that preferably will be connected on the electric connector 120 cut off.Therefore, after the investigation of confirming operation and fault, must be once more with being connected to all on pin interval narrow and small the single line pin 152 and coaxial pins 154 of the cable 112 that is connected with image unit or Switch, operation is loaded down with trivial details.

In addition, the single line pin 152 of electric connector 120 and coaxial pins 154 are arranged to the axially parallel with joint 131, and vertical with cap assembly 138, insulator 139 and substrate 141.Therefore, on single line pin 152 and coaxial pins 154 during connection cord line 112, perpendicular to the mode of the operation post of level electric connector 120 is set with single line pin 152 and coaxial pins 154.Be connected on the single line pin 152 and coaxial pins 154 of this plumbness by the leading section of welding, and make this cable 112 coaxial with single line pin 152 and coaxial pins 154 with cable 112.Promptly, in the operation that cable 112 is connected on single line pin 152 and the coaxial pins 154, need frequent attention not make near the bending of cable 112 from welding portion, perhaps need often to note contact and the welding of other cable 112 is arrived in overslaugh, perhaps need to prepare the instrument that does not keep with making cable 112 bendings with adjacent single line pin 152 or coaxial pins 154.Therefore, must give cable 112 is connected the more attention of operation on a plurality of single line pins 152 and the coaxial pins 154, the activity duration is long.

In addition, between the single line electric wire 155 and coaxial cord 156 of single line pin 152 and coaxial pins 154, cable 112, be welded to connect sometimes across electronic units such as diode or resistance.Under this situation, not only should be noted that the bending of cable 112, be also noted that the bending of the lead-in wire of electronic unit, so it is more loaded down with trivial details and the time is long that cable 112 is connected operation on a plurality of single line pins 152 and the coaxial pins 154.

Like this, disconnect a plurality of electric wires of the cable 112 is connected with the single line pin and the coaxial pins at narrow interval, direct once more or be connected to the unusual complexity of reconditioning work itself on single line pin and the coaxial pins via electronic unit, spend the more time, must carry out cautiously.

And when carrying out the investigation of above-mentioned confirming operation or fault, for cable 112 is connected on the checking tool, the insulated cladding of strip cable line 112 front ends is welded on the checking tool.When utilizing the investigation of confirming operation that checking tool carries out and trouble location to finish, in order to remove and being connected of checking tool, the front end of cable 112 is cut off.With the front end of the cable 112 that being connected of this checking tool has been cut off once more by welding and be connected with coaxial pins 154 with the single line pin 152 of electric connector 120, insulated cladding is stripped from.Therefore, the front end of cable 112 all is cut off when carrying out the investigation of confirming operation and trouble location at every turn, so the total length of cable 112 shortens.If the total length of this cable 112 shortens, then the operation of connection again of confirming operation, fault investigation and cable 112 becomes difficulty, needs the more time.
