Detailed description of the invention
In order to provide effective implementation, the invention provides following embodiment, below in conjunction with Figure of description, the embodiment of the present invention is illustrated.
Present invention firstly provides a kind of optical module connecting device, schematic diagram as shown in Figure 1, including guard mechanism 101, connecting mechanism for rotating 102, shell 103, draw ring 104；Wherein:
Guard mechanism 101, for blocking the light that laser instrument sends from the transmission mouth of shell, the light being arranged at described shell sends mouth place and covers the transmission mouth of optical module, is connected with shell by described connecting mechanism for rotating；
Connecting mechanism for rotating 102: be used for connecting guard mechanism 101 and optical module, and make guard mechanism 101 can rotate to the second position around the junction of guard mechanism Yu optical module from primary importance；
Shell: there is the space for holding optical module 105, and there is the opening of the receiving port sending mouth and light as light；
Draw ring 104: be arranged at described shell aperture place, between described guard mechanism 101 and described transmission mouth；Can rotate around the link position of draw ring with shell；For fixing and unclamp the connection of described shell and described optical module；
Described primary importance is that guard mechanism 101 Guan Bi hides in the position sending mouth of described light and the transmission inc position of mouth of guard mechanism 101 and described light；The described second position is another in the position sending mouth of the guard mechanism 101 Guan Bi described light of covering and the transmission inc position of mouth of guard mechanism 101 and described light.
Described connecting mechanism for rotating 102, owing to being blocked by shell 103 and draw ring 104, is adopted in FIG and is represented by dashed line.Owing to optical module 105 is blocked by shell 103, therefore the part in optical module 105 portion in the enclosure is adopted and is represented by dashed line in FIG.
As can be seen from above, optical module connecting device provided by the present invention, various optical modules can be applicable to, there is the shell for holding optical module, at the transmission mouth place of the light of shell glazing module, be provided with guard mechanism, thus the laser instrument that this connecting device can block optical module physically sends, by shell, the light that mouth sends, meanwhile, described optical module connecting device can also avoid dust to enter from the transmission mouth of light, extends the service life of optical module.
In an embodiment of the present invention, under described guard mechanism closure state, the transmission mouth of described light is blocked by described guard mechanism completely.
In the ordinary course of things; if the transmission mouth part of described light is blocked by described guard mechanism; namely the transmission mouth of described light is not exclusively covered under guard mechanism closure state; the light that laser instrument is emitted by the light transmission mouth on shell also is able to the part that is blocked, it is also possible to play the effects such as certain human eye protection.But in order to protect human eyes from influence of laser irradiation to the full extent; the transmission mouth of described light is completely covered under described guard mechanism closure state; as shown in Figure 2; guard mechanism 101 is completely covered light and sends mouth 1051; and block draw ring 104 sending mouth 1051 place; and the light entrance port 1052 on the left of Fig. 2, in embodiments of the present invention without blocking.
