Description

Technical Field

[0001] The present invention relates to the technical field of camera lenses, and in particular to a lens circuit board structure matching E-mount, Z-mount and X-mount cameras. Background Art

[0002] Due to their lightweight size and gradually improved chip photosensitivity, micro-single cameras have been replacing traditional SLR cameras in recent years. As a core component, micro-single lenses have also entered the field of vision of more and more consumers. Due to the technological innovation of micro-single cameras, traditional SLR lenses cannot be matched with new micro-single cameras, which has given rise to a large number of demands for third-party lenses.

[0003] Since China does not have the ability to design and manufacture SLR or micro-single cameras, and Japanese and German cameras have monopolized the global market, domestic lens manufacturers can only be forced to make supporting lenses for camera manufacturers such as Canon, Nikon, and Sony, which are usually called secondary factory lenses. However, the investment cost and cycle of developing a secondary factory lens are very high and long, and many camera manufacturers, whether Canon, Nikon, Sony, Fuji, etc., do not have universal lenses. The bayonet mounts for connecting their cameras and lenses are also different, and the number and position of the contact interfaces inside are also inconsistent, resulting in the need for a large change in the components of the secondary factory micro-single lens to adapt to different cameras. This will bring some difficulties to the design and production of secondary factory lenses. For example, if the same specification of lens is to be able to meet the use of the micro-single cameras of the above-mentioned manufacturers at the same time, it is necessary to develop a secondary factory lens for each manufacturer's micro-single camera.

[0004] Since the circuit board in the aftermarket lens needs to be electrically connected to the contact interface on the original lens through a flexible circuit board, and the number and position of contacts on the contact interface on each original lens are inconsistent, the original lens with a large number of contacts needs to use a flexible circuit board with a larger line width. Correspondingly, the socket of the circuit board in the aftermarket lens is also wider, and the circuit boards cannot be shared. As a result, multiple circuit boards need to be developed and designed for multiple original lenses of the same specification. Since the circuit board is a major component in the aftermarket lens with a complex design and high cost, this will increase the variety of materials and the difficulty of project management, as well as higher procurement and warehousing costs, which is not conducive to reducing the production costs of aftermarket lens manufacturers. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the circuit board in the third-party lens cannot match lenses of different manufacturers at the same time, thereby providing a lens circuit board structure that matches E-mount, Z-mount and X-mount cameras.

[0012] Furthermore, N first-type conductive circuits are cross-arranged on different thickness layers of the first-type flexible flat cable.

[0013] Furthermore, the contact group structure on the second-type lens includes M contact pins; the second-type contact wiring part is provided with M second-type contacts arranged one-to-one corresponding to the M contact pins, and the second-type wiring gold finger part is provided with M second-type conductive contact pieces, and the M second-type conductive contact pieces and the M second-type contacts are electrically connected through second-type conductive circuits, respectively, wherein M is a positive integer greater than 1; and the M second-type conductive circuits are cross-arranged on different thickness layers of the second-type soft cable.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] like Figure 1-8 shows a lens circuit board structure matching E-mount, Z-mount and X-mount cameras, which is applied to a third-party lens that is connected to an original lens. The circuit board structure includes a hard circuit board 100, a first-class flexible flat cable 200, a second-class flexible flat cable 400, a third-class flexible flat cable 600 and a fourth-class flexible flat cable 800; a socket 110 is provided on the hard circuit board 100, and the socket 110 is specifically a 19-pin socket 110. The cable widths of the first type of flexible flat cable 200, the second type of flexible flat cable 400, the third type of flexible flat cable 600 and the fourth type of flexible flat cable 800 are equal, so that one end of the first type of flexible flat cable 200, the second type of flexible flat cable 400, the third type of flexible flat cable 600 and the fourth type of flexible flat cable 800 can be replaced and electrically connected to the socket 110 of the rigid circuit board 100, and the other ends of the first type of flexible flat cable 200, the second type of flexible flat cable 400, the third type of flexible flat cable 600 and the fourth type of flexible flat cable 800 are respectively electrically connected to the contact group structures of different types of lenses. It can be understood here that the number of flexible flat cables is not limited to four categories. No matter how many types of flexible flat cables there are, as long as the cable widths of all flexible flat cables are equal and can be electrically connected to the same type of socket 110, they are within the protection scope of this application.

[0036] Specifically, the first type of flexible flat cable 200 includes a first type of flat cable gold finger portion 210 and a first type of contact flat cable portion 220 disposed corresponding to the contact group structure position on the first type of lens 300.

[0037] With this lens circuit board structure that matches E-mount, Z-mount, and X-mount cameras, multiple flexible cables connecting multiple original lenses can share the same socket 110 and hard circuit board 100. When designing multiple third-party lenses for multiple original lenses of the same specification, only one hard circuit board 100 needs to be developed, which is conducive to reducing the types of electronic parts required for multiple third-party lenses, shortening the R&D and trial production cycle, reducing procurement costs and warehousing and testing costs, and improving R&D and production efficiency.

The common Sony E-mount flexible flat cable, the common Nikon Z-mount flexible flat cable, the innovative Fuji X-mount flexible flat cable, and the innovative Sony E-mount flexible flat cable have the same cable width, but different internal wiring structures.

A connection hole is provided at one end of the second type contact wiring part 420 close to the second type cable gold finger part 410, and the second type flexible flat cable 400 is fixed to the second type lens 500 by a screw passing through the connection hole.

[0044] 1. Multiple flexible cables connecting multiple original lenses can share the same socket 110 and hard circuit board 100. When designing multiple third-party lenses for multiple original lenses of the same specification, only one hard circuit board 100 needs to be developed, which is conducive to reducing the types of electronic parts required for multiple third-party lenses, shortening the R&D and trial production cycle, reducing procurement costs and warehousing and testing costs, and improving R&D and production efficiency.
