Problems solved by technology

[0017] In addition, with the rotation of the imaging cables 46, 47, a torsional force is easily applied to the connecting portion of the imaging cables 46, 47 and the imaging device, resulting in disconnection, and the core wires of the imaging cables may contact each other to cause a short circuit. and other bad situations
[0018] Even if the adhesive filler softens, the cable bundling part of the heat-shrinkable tube is deformed, and a torsional force is generated in the connecting part of the electric unit (imaging device) and the cable (imaging cable), the above-mentioned defects will not occur immediately. However, due to repeated heat treatment on electronic equipment (endoscopes), there are disadvantages of reduced durability and shortened product life

no. 1 Embodiment approach

[0043] figure 1 - FIG. 6 shows the 1st Embodiment of this invention.

[0044] figure 1 A rigid electronic endoscope (hereinafter simply referred to as an "endoscope") 1 capable of being autoclaved (autoclaved) is shown in FIG.

[0045] The endoscope 1 includes: an insertion part 2; an operation part 3 provided continuously to the proximal end of the insertion part 2; a universal cord 4 extending from the operation part 3; a scope connector 5 ; and an electrical connector 6 provided at the end of the cable extending from the side of the scope connector 5 .

[0046] Further, the insertion portion 2 includes a distal end portion 11 , a curved portion 12 provided continuously to the distal end portion 11 , and a rigid portion 13 provided between the curved portion 12 and the operation portion 3 in this order from the distal end.

[0047] The operation part 3 is provided with two bending operation levers 14 and 15 for bending the bending part 12 up and down and left and right ...

no. 2 Embodiment approach

[0118] Figure 7 , Figure 8 The second embodiment of the present invention is shown.

[0119] In the above-mentioned first embodiment, the existing mist prevention element cable 58 and heat dissipation cable 60 function as twist prevention members, but in this embodiment, a dedicated The anti-twist member 61 is to block the rotational movement of the two imaging cables 46 and 47 by the anti-twist member 61 and the heat dissipation cable 60 as the second cable.

[0120] Depending on the endoscope 1 to be used, the above-mentioned cable 58 for the fog prevention element may not be necessary.

[0121] In such a case, the cable binding part 57a of the heat shrinkable tube 57 fastens and binds the first imaging cable 46, the second imaging cable 47, and the heat dissipation cable 60. The same effect as that of the above-mentioned first embodiment can be obtained by using the dedicated twist preventing member 61 for the cable 58 for the element.

[0122] That is, as Figure 7 ...

no. 3 Embodiment approach

[0133] Figure 9 The third embodiment of the present invention is shown.

[0134] Depending on the endoscope 1 to be used, both the aforementioned mist prevention element cable 58 and heat dissipation cable 60 may not be necessary.

[0135] In such a case, by using a pair of dedicated twist preventing members 61 instead of the two cables 58 and 60 , the same effect as that of the first embodiment described above can be obtained.

[0136] In addition, since the rear end portion 61b of the twist preventing member 61 of the present embodiment is thinner than the diameters of the two imaging cables 46 and 47, the center of the rear end portion 61b is arranged in the cable bundling portion 57a. The position where the central axis of the heat-shrinkable tube 57 deviates.

[0137] In this way, in this embodiment, by providing the dedicated twist preventing member 61, even in an endoscope that is not provided with both the mist prevention element cable 58 and the heat radiation cabl...

Abstract

The electrical unit of the present invention has: flexible first and second imaging cables (46, 47); and a cable binding part (57a) for binding the first and second imaging cables (46, 47) ) heat shrinkable tube (57); the first and second substrates (44, 45) connected with the first and second camera cables (46, 47); and the first and second camera cables (46, 47 ) are bundled together by the cable bundling part (57a) and protrude from the cable bundling part (57a) toward the first and second substrates (44, 45) side wire (60); and the reinforcing frame (56) that fixes the core wires (58a, 60a) of these two cables (58, 60), and the two cables (58, 60) are in the cable binding part ( 57a) is disposed at a position deviated from the central axis of the heat-shrinkable tube (57).

Description

technical field [0001] The present invention relates to an electrical unit in which it is difficult to transmit torsion of the first cable, which occurs when the first cable is looped, to the electrical component side, and an endoscope equipped with the electrical unit. Background technique [0002] As the functions of electronic equipment such as endoscopes increase, signals transmitted to electrical units such as imaging devices mounted on the electronic equipment increase, and the number of cables inevitably increases. [0003] Like an electronic device such as an endoscope, it has a relatively flexible elongated portion, a plurality of cables are inserted through the elongated portion, and the distal end of each cable is connected to an electric unit arranged on the distal end side of the electronic device. In this case, when the operator goes around the elongated portion of the electronic device, a twisting force in the rotational direction is generated in each cable ar...
