Abstract
An endoscope with a T-shaped flexible circuit board includes: a base mounting frame, a flexible circuit, a photosensitive element, two light emitting elements and a camera. The photosensitive element, the two light emitting elements and the camera are mounted onto the T-shaped flexible circuit board, then the flexible circuit board deforms to fit in the base mounting frame. During assembly, the photosensitive element, the two light emitting elements and the camera are maintained in the same orientation, and the T-shaped flexible circuit can be pushed into the base mounting frame simply by applying a force in a single direction parallel to the orientation direction of the photosensitive element, the two light emitting elements and the camera.
Claims3
An endoscope with a T-shaped flexible circuit board comprising;
- A U-shaped base mounting frame with two arm portions and a connecting portion connected between one ends of the two arm portions, between another ends of the two arm portions being defined a gap, each of the two arm portions extending from the connecting portion to the gap and having a length, a surface of the base mounting frame located between the two arm portions and the connecting portion being defined as an inner surface, and another surface opposite the inner surface being defined as an outer surface of the base mounting frame, each of the two arm portions having an end surface which extends in a forward direction;
- the T-shaped flexible circuit board including a mounting portion electrically connected to an electric connecting portion, the mounting portion and the electric connecting portion defining a non-zero angle with respect to each other, the T-shaped flexible circuit bard including a mounting surface and a connecting surface, the connecting surface being abutted against the inner surface of the base mounting frame in such a manner that the mounting portion is abutted against the end surfaces, the arm portions and the connecting portion of the base mounting frame, and the electric connecting portion bridges over the connecting portion and extends out of the base mounting frame to electrically connect a power supply or an imaging device;
- a photosensitive element electrically connected to the mounting portion of the flexible circuit board and mounted on the mounting surface;
- two light emitting elements being electrically connected to the mounting portion of the flexible circuit board, located in alignment with the end surfaces of the arm portions of the base mounting frame, and disposed in the forward direction;
- and
- a camera including a lens at one end and an engaging groove at another end thereof, and having a length larger than the length of the arm portions, the camera being disposed on the mounting surface of the mounting portion of the flexible circuit board in such a manner that the camera is disposed in a space defined by the two arm portions and the connecting portion of the base mounting frame, the photosensitive element is engaged in the engaging groove, the lens of the camera protrudes out of the gap between the arm portions of the base mounting frame and is disposed in the forward direction, and the camera is disposed in the forward direction and protrudes out of the end surfaces of the base mounting frame and also protrudes out of the two light emitting elements.
