Detailed Description

The following description provides many different embodiments, or examples, for implementing different features of the invention. The particular examples set forth below are illustrative only and are not intended to be limiting.

In the utility model, the near end and the far end are the far and near positions of the structure relative to the operation of human body in the use environment, so as to conveniently describe the position relationship between the components and facilitate understanding; "proximal" and "distal" are positional relationships relative to the operator.

Referring to fig. 1 and 2, the present invention provides an endoscope flexible electrical connector, comprising: a flexible circuit board 13 and a crystal oscillator 40, wherein the flexible circuit board 13 is in a strip shape, and the flexible circuit board 13 is used for extending from the front end of an insertion part (not shown in figure 1) to the rear end of the insertion part; compared with the existing mode of welding by adopting wires, the flexible circuit board 13 has the advantages that the arrangement of the neatly planned lines of the flexible circuit board 13 is realized, and the anti-interference capacity of the endoscope can be effectively improved by the anti-interference coating coated outside the flexible circuit board 13.

The crystal oscillator 40 is disposed on the flexible circuit board 13, and both the flexible circuit board 13 and the crystal oscillator 40 are disposed in the insertion portion of the endoscope. In the prior art, the crystal oscillator 40 is arranged in the handle of the endoscope, and the crystal oscillator 40 is separated from the image sensor 12 at the front end of the insertion part by the length of the insertion part, so that the anti-interference performance of signals is weakened; therefore, it is preferable that the crystal oscillator 40 is provided near the distal end of the insertion portion of the endoscope, and the shorter the distance between the crystal oscillator 40 and the image sensor 12, the greater the interference resistance of the endoscope image display.

In addition, if the crystal oscillator 40 is not integrally disposed on the flexible circuit board 13, but the crystal oscillator 40 is directly connected to a signal line for transmitting an image signal, several points need to be soldered, and it needs to be considered how the soldered crystal oscillator 40 is disposed in the inner space of the insertion portion because the space in the insertion portion is extremely limited; meanwhile, in order to improve the comfort of the patient, the external diameter of the insertion part is required to be reduced, so that the accommodating space in the insertion part is further compressed; therefore, when the manner in which the signal line is directly soldered to the crystal oscillator 40 is adopted, it is difficult to dispose the crystal oscillator 40 in the insertion portion, and only the crystal oscillator 40 can be disposed in the handle, however, the crystal oscillator 40 disposed in the handle lengthens the signal transmission distance, resulting in a reduction in the interference resistance. Therefore, for the special needs of reply endoscope to reducing the insertion part size, the utility model discloses in, with crystal oscillator 40 integrated on flexible circuit board 13, through reasonable arranging, be favorable to reducing crystal oscillator 40's size to can arrange crystal oscillator 40 in the insertion part, reduce the interference killing feature who has improved the endoscope.

Preferably, when the flexible electrical connector is disposed in the insert portion, the crystal oscillator 40 is disposed near the front end of the insert portion. Alternatively, when the flexible electrical connector is disposed at the insertion portion, the crystal oscillator 40 is located at the front end portion of the passive bending tube. Specifically, as shown in fig. 3, the crystal oscillator 40 is disposed behind the active bending section 30(L1) of the insertion portion and at the front end of the passive bending section (L2). The reason for this is that since the crystal oscillator 40 itself has a certain rigidity or brittleness, being provided in the active bending section 30(L1) will easily affect the bending of the active bending section 30(L1), resulting in an unsmooth or stuck bending process, and in addition, the crystal oscillator 40 is easily crushed and damaged when the active bending section 30(L1) is bent. Meanwhile, the crystal oscillator 40 is arranged at the front end of the passive bending pipe section (L2), so that the distance between the crystal oscillator 40 and the image sensor 12 can be reduced to the greatest extent, and the anti-interference performance of the endoscope image display is improved.

Please refer to fig. 4, the present invention further provides a camera module 10, which includes the above-mentioned flexible electrical connector, a lens 11 and an image sensor 12, wherein one side of the image sensor 12 is connected to the lens 11, and the other side of the image sensor 12 is connected to the front end of the flexible circuit board 13. Specifically, connect through a plurality of contacts 121 that set up between image sensor 12 and the flexible circuit board 13, can connect into a relatively independent module with image sensor 12 and flexible circuit board 13 in actual production process, make things convenient for the later stage installation, perhaps set up camera lens 11, image sensor 12, flexible circuit board 13 into a whole, can improve the installation effectiveness of later stage endoscope.
