Background

Traditional consumer cables such as HDMI, USB2.0 and TYPE C all adopt copper cable transmission, with transmission bandwidth and speed requirement higher and higher, simultaneously have requirements such as lossless transmission, use optic fibre as transmission cable and more popularize, have developed into TYPE consumer photon class products such as HDMI-AOC and TYPE C-AOC. However, the commercial AOC products of consumer light type mainly have the following application defects:

1. because the bending radius of the optical fiber is too small, the optical fiber is easy to break and cannot transmit signals, and the communication interfaces at the two ends are provided with photoelectric chips, the price is high, so that a user has to replace the whole product, and the use cost is relatively high;

2. in the production process, the host and the cable need to be welded and connected to complete the whole machine, and the process is complex;

3. the length of the product is determined in the production process, and the cable length cannot be changed at the later stage;

although the HDMI-AOC on the market at present is converted by a TYPE-AOC as an interface and forms an HDMI-AOC product, the problem that the optical fiber cable cannot be replaced due to breakage is also solved.

Disclosure of Invention

In order to solve at least one of the problems in the prior art, the invention provides a photonic communication interface supporting plug and pull interchange of an optical fiber cable, which solves the problem that a cable needs to be replaced when a user uses a consumer photonic product of an optical fiber or a photoelectric mixed cable or the cable is difficult to replace after the cable is broken, and practically improves the convenience and cost saving property of the user.

The technical scheme adopted by the invention is as follows:

the utility model provides a support photon communication interface that optic fibre cable plug exchanged, includes cable and host interface, and the host interface includes the circuit board, and circuit board one end is equipped with communication interface, and the circuit board other end is equipped with cable detachable grafting end, can realize the transmission of information between circuit board and the cable after circuit board and cable grafting are accomplished.

In order to form better protection for the cable and the host interface, as preferable, a protective shell is further sleeved outside the connection interface of the circuit board and the cable, the protective shell comprises a front end cover and a rear end cover which are detachably connected, the rear end cover is sleeved outside the cable and can slide on the cable, and the front end cover and the rear end cover can be locked at a certain position of the host interface after being connected and can protect the connection interface and the circuit board.

For the detachable connection mode of the front end cover and the rear end cover, a threaded connection mode can be adopted, and after the front end cover and the rear end cover are connected in the arrangement mode, a certain space exists among the protective shell, the circuit board and the communication interface, and the circuit board is relatively poor in protection performance; the front end cover and the rear end cover can be connected in an interference fit mode, the shape and the size of the front end cover are matched with the circuit board and the communication interface, and the front end cover and the rear end cover are connected in a translational motion mode in the opposite direction; or the front end cover and the rear end cover are detachably connected in a buckling mode. The detachable connection manner of the front end cover and the rear end cover is not limited to the above manner, and any manner capable of realizing the detachable connection of the front end cover and the rear end cover is within the optional implementation scope of the invention.

For the positioning of the front end cover and the rear end cover after connection, the front end cover and the communication interface can be fixedly connected relatively, namely, the front end cover and the communication interface can not slide relatively in a left-right staggered manner, and then the rear end cover is connected with the front end cover, and certainly, the front end cover and the communication interface can also be fixedly connected directly. Or the rear end cover is fixedly connected with the cable, and then the rear end cover is connected with the front end cover. Or a stop member is arranged at the host interface and the cable at a certain position, so that the movement of the protective shell is limited after the front end cover and the rear end cover are connected.

In order to conveniently sleeve the rear end cover on the cable, the rear end cover can adopt a split buckling connection mode, the two rear end covers are sleeved outside the cable and are buckled and connected, and therefore the integral installation and the replacement and use of different cables can be more convenient.

In order to better limit the sliding of the protective shell and facilitate the detachable connection of the front end cover and the rear end cover, preferably, a first bulge is arranged at one end of the communication interface close to the circuit board, a first clamping frame matched with the first bulge is arranged at one end of the front end cover, and the front end cover slides into the first bulge from one end of the communication interface and stops at the position of the first bulge; the cable is also provided with a second bulge at one end close to the circuit board, one end of the rear end cover is provided with a second clamping frame matched with the second bulge, and the sliding process of the rear end cover on the cable is stopped at the position of the second bulge.

After the free end of the elastic sheet extends into the front end cover, the rear end cover and the front end cover can be detached or separated due to friction between the end part of the free end of the elastic sheet and the inner side wall of the front end cover.

In order to further enhance the stability of the connection between the rear end cover and the front end cover, preferably, two groups of elastic pieces are arranged and distributed on two sides of the rear end cover.

In order to further ensure the stability of the whole structure after the rear end cover is connected with the front end cover, preferably, the free end of the elastic sheet is provided with a chamfer bulge, and the inner side wall of the front end cover is provided with a clamping groove matched with the chamfer bulge; when the elastic sheet slides into the front end cover and is clamped into the clamping groove, the front end cover is abutted with the rear end cover; when the protective shell needs to be disassembled, the side wall of the rear end cover is pressed, and the chamfer protrusions are separated from the clamping grooves, so that the front end cover and the rear end cover can be disassembled.

In order to better realize the detachable connection between the cable and the circuit board and simultaneously ensure the signal transmission between the circuit board and the cable, as an optimization, one end of the cable is provided with an electric connector male end component, and the inserting end on the circuit board is an electric connector female end component which is detachably and electrically connected with the electric connector male end component; the optical module is electrically connected with the circuit board and comprises an optical element and an optical transceiving element electrically connected with the circuit board, and the optical element and the optical transceiving element can realize information transceiving.

In order to facilitate the production of the host interface and the specific structural design of the optical module, it is preferable that the optical module and the male terminal assembly of the electrical connector are separately provided. Compared with the integrated arrangement of the optical module and the male end component of the electric connector, the optical module is more conveniently designed by a manufacturer, and the assembly line production of the manufacturer is more convenient.

Preferably, the host interfaces are provided with two groups and distributed at two ends of the cable, and the communication interfaces of the host interfaces at the two ends can adopt different communication interfaces.

Wherein, the interface of the communication interface can be any one of the specifications conforming to HDMI, USB2.0 and TYPE C.
