It is more than two.
Referring to the sealing structure for the MCL laser that Fig. 1~3, the embodiment of the present invention provide, including mounting bracket 1 and MCL
Laser 2, the mounting bracket 1 are equipped with laser installing port 11, and the MCL laser 2 is equipped in the laser
In installing port 11, sealing ring 3 is equipped between the side wall of the MCL laser 2 and the laser installing port 11, the MCL swashs
Side wall one week of light device 2 is equipped with annular groove 21, and the sealing ring 3 includes the embedded division 31 in the annular groove 21 and is located at annular groove 21
Outer bending part 32, the bending part 32 are bonded with the side wall of the MCL laser 2, the outside bending place of the bending part 32
The first chamfer 33 is formed, the edge of the laser installing port 11 forms the second chamfer 12, first inclined-plane
Chamfering 33 fits with second chamfer 12.
The sealing structure and light source module group of MCL laser 2 provided in an embodiment of the present invention, since sealing ring 3 includes being located at
Embedded division 31 in annular groove 21 and the bending part outside annular groove 21 32, the side of the bending part 32 and the MCL laser 2
The outside bending place of wall fitting, the bending part 32 forms the first chamfer 33, the edge of the laser installing port 11
The second chamfer 12 is formed, first chamfer 33 fits with second chamfer 12.It makes full use of as a result,
21 structure of annular groove of MCL laser 2, using the oblique sealing means in unconventional side, by sealing ring 3 and matched peace
Dress 1 face of bracket is made into slanting, and which increases the effective lengths of dust seal, while having reserved foot to the assembly of laser
Enough spaces, and then solve the problems, such as sealing space deficiency, it can satisfy the stringent Dustproof experiment requirement of light source module group, improve
Using effect and the service life of laser and light source module group.
In order to improve the effective length of sealing surface, as shown in figure 3, it is preferred that by the first chamfer 33 and second inclined-plane
The width D of chamfering 12 is set greater than or is equal to 1 millimeter.Sealing effect can be improved as a result,.
Wherein, the material of sealing ring 3 is preferably fluorubber, viton seal ring 3 while realizing dust seal also
Effect avoid conventional seals material at high temperature volatile organism the problem of.The hardness of sealing ring 3 can be 50 °~65 °, excellent
55 ° are selected as, sealing ring 3 there can be certain amount of elastic deformation as a result, to meet the needs of interference fit.
Optionally, the MCL laser 2 can be connected through a screw thread or snap connection with the mounting bracket 1.For the ease of
Installation, can be arranged guide groove in mounting bracket 1, and the guide groove extends along the loading direction of the MCL laser 2.
The MCL laser 2 and the installation process of mounting bracket 1 are as follows: being substantially inserted in it first with the elastic force of sealing ring 3
In the annular groove 21 of MCL laser 2, the peripheral raised bead pressing of sealing ring 3 is embedded into MCL laser in sequence with nonconductive tweezer
In 2 annular grooves 21, guarantee that insertion is complete and smooth.Then MCL laser 2 is slid into laser by the guide groove of mounting bracket 1
In installing port 11, positioning column is passed through, realizes positioning of the MCL laser 2 in mounting bracket 1.At this time the first chamfer 33 with
Second chamfer 12 is combined together.Laser is fixed on bracket finally by screw or buckle, in screwed lock
Preferably guarantee uniform force between the first chamfer 33 and second chamfer 12 using diagonally locking during attached,
Unbalance stress is avoided to cause to occur to tilt between the two to cause poor sealing, during screw locking, the first chamfer 33
Gradually interference fits together with second chamfer 12, thus can guarantee that sealing is close, it is preferable that the first chamfer
33 may be designed as 0.2~0.5 millimeter, preferably 0.3mm with the magnitude of interference of second chamfer 12.It can both protect as a result,
The close extruding force that laser will not be made to be subject to again of card sealing is excessive.
Since 2 size of MCL laser is small, also small, adjacent with MCL laser 2 lens of the size of corresponding optical path framework
Diameter is also smaller, the distance between this lens and MCL laser 2 also very little.For this feature, precision and Cheng Benfang are taken into account
Lens can be also also fixed on together in mounting bracket 1 by face, specifically, as shown in Fig. 2, lens can be arranged in mounting bracket 1
Installing port 13, and keep lens installing port 13 opposite with the light-emitting surface of MCL laser 2, then lens 4 are fixed on by sealant
In lens installing port 13, to guarantee the air-tightness of laser light source, optical attenuation is reduced.
Second aspect, as shown in figure 4, the embodiments of the present invention also provide a kind of light source module group, including main casing 100,
The sealing structure 200 of any of the above-described MCL laser 2 as described in the examples is equipped at the light inlet of the main casing 100.
Light source module group provided in an embodiment of the present invention, due to sealing ring 3 include embedded division 31 in the annular groove 21 and
Bending part 32 outside annular groove 21, the bending part 32 are bonded with the side wall of the MCL laser 2, the bending part 32
Outside bending place forms the first chamfer 33, and the edge of the laser installing port 11 forms the second chamfer 12, institute
The first chamfer 33 is stated to fit with second chamfer 12.The annular groove 21 of MCL laser 2 is taken full advantage of as a result,
Structure, using the oblique sealing means in unconventional side, sealing ring 3 and matched 1 face of mounting bracket are made into it is slanting,
Which increases the effective lengths of dust seal, while having reserved enough spaces to the assembly of laser, and then solve
The problem of sealing space deficiency can satisfy the stringent Dustproof experiment requirement of light source module group, improve laser and light source module group
Using effect and the service life.
Wherein, pass through 3 interference of sealing ring of viton seal ring 3 or other materials between mounting bracket 1 and main casing
Form is realized airtight.
Mounting bracket 1 plays heat radiation module simultaneously and fixes in this scheme, and hygrosensor is fixed, MCL laser 2 is solid
The effects of fixed, fixation of switching circuit board 5, fixed lens.Wherein: heat radiation module and laser are placed in front, and two sides, which hollow out, puts
Two switching circuit boards 5 are set, lens 4 and the connection with light source main casing 100 are placed in rear.It also achieves at the same time following
Function, it may be assumed that connection, the sealing of lens, mounting bracket between the sealing of MCL laser 2, MCL laser 2 and switching circuit board
It is airtight between 1 and main casing.One multi-purpose, and space is utilized to the greatest extent, realizes the miniaturization of light source regional area
Design.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
