Come off, and both modes can not all be used in printed board.
The content of the invention
The utility model embodiment technical problem to be solved is there is provided a kind of optical fiber clamping joint, simple in construction, production
Cost is low, can reliably fix optical fiber.
In order to solve the above technical problems, the utility model embodiment is adopted the following technical scheme that：A kind of optical fiber clamping joint, bag
The aperture for including the through hole in the middle part of the cylinder that front and rear insertion supplies optical fiber to pass through, the cylinder is not more than the external diameter of optical fiber, and described
The hole wall of through hole is provided with the burr for being used for increasing frictional resistance between hole wall and optical fiber outer wall.
Further, the burr is netted line.
Further, the small 0 ~ 0.5mm of external diameter of the aperture ratio optical fiber of the through hole.
Further, the lateral wall of the cylinder is also integrally formed provided with for the optical fiber clamping joint to be fixed into printing
Fixture on plate.
Further, what the fixture included that one end passes through that the lateral wall of connecting portion and the cylinder is integrally connected hangs
Groove gap is formed between arm, the lateral wall of the cantilever and cylinder, the width of the groove gap and the thickness of printed board match, and institute
Stating cantilever and being provided with the one side of the lateral wall towards cylinder is used for falling for the corresponding hook cooperation of block button hole corresponding with printed board
Button.
Further, constitute the cylinder of cell wall of the groove gap both sides and the surface facing each other of the cantilever is
The plane being parallel to each other.
Further, its material is engineering plastics.
Compared with the existing technology, the utility model embodiment at least has the advantages that：The utility model embodiment
By setting the through hole for being not more than fibre external diameters with netted striped to fix in the middle part of the cylinder that front and rear insertion is passed through for optical fiber
Optical fiber, simple in construction, production cost is low, easy to operate, can reliably fix optical fiber.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment optical fiber clamping joint.
Fig. 2 is the cross-sectional view of the utility model embodiment optical fiber clamping joint.
Embodiment
The application is described in further detail with specific embodiment below in conjunction with the accompanying drawings.It should be appreciated that following signal
Property embodiment and illustrate only to be used for explaining the present invention, it is not as a limitation of the invention, moreover, in the case where not conflicting,
The feature in embodiment and embodiment in the application can be combined with each other.
As shown in Figure 1 and Figure 2, a kind of optical fiber clamping joint involved by the utility model embodiment, including front and rear insertion supply light
The cylinder 1 that fibre 4 is passed through, the aperture of the through hole 11 at the middle part of cylinder 1 is not more than the external diameter of optical fiber 4, such as through hole 11
Small 0 ~ the 0.5mm of external diameter of aperture ratio optical fiber 4, and the through hole 11 hole wall be provided be used to increasing hole wall and the outer wall of optical fiber 4 it
Between frictional resistance burr, burr is netted line, and net striped can increase the frictional force between optical fiber clamping joint and optical fiber 4；Pass through
The aperture of through hole 11 is not more than the external diameter of optical fiber 4, using interference fit, optical fiber 4 can be made closely to be connected with optical fiber clamping joint, no
It is easy to fall off.
The lateral wall of cylinder 1 is also integrally formed provided with the fixture for being used to be fixed to the optical fiber clamping joint in printed board
2, fixture 2 includes the cantilever 22 that one end is integrally connected by connecting portion 21 with the lateral wall of the cylinder 1, cantilever 22 and cylinder
Groove gap 3 is formed between 1 lateral wall, the width of the groove gap 3 and the thickness of printed board match, and the cantilever 22 is in direction
The one side of the lateral wall of cylinder 1, which is provided with, is used for the back-off 23 of block button hole corresponding with printed board corresponding hook cooperation, and groove gap 3 is used
In housing printed board, back-off 23 is caught in the corresponding block button hole of printed board, and one lower cantalever 22 of light pressure can be by sonet card during dismounting
Joint is removed from printed board, can be to freely being mounted and dismounted between optical fiber clamping joint and printed board.Constitute groove gap 3
The cylinder 1 of the cell wall of both sides and the surface facing each other of cantilever 22 are the plane being parallel to each other, and optical fiber clamping joint is fixed on
When in printed board, the cell wall of the both sides of groove gap 3 of optical fiber clamping joint is close to printed board, so that optical fiber clamping joint is reliably fixed on print
Displacement and rotation are not produced in making sheet.Material uses engineering plastics, can produce optical fiber clamping joint, reduction production in batches using mould
Softening can be expanded after product cost, and engineering plastics heating, is easy to penetrate optical fiber 4 in optical fiber clamping joint through hole 11.
In use, optical fiber clamping joint is fixed on optical fiber 4 by the first step, optical fiber clamping joint heat gun is blown into heat first,
Optical fiber clamping joint is set somewhat to soften, the through hole 11 of heated rear optical fiber clamping joint can become big, then the requirement position being set on optical fiber 4
Put, wait optical fiber clamping joint after the cooling of optical fiber clamping joint to be just firmly fixed on optical fiber 4；Second step is to be mounted in optical fiber clamping joint
In printed board, the corresponding block button hole of back-off 23 with the cantilever 22 of the fixture 2 of optical fiber clamping joint is reserved first in printed board,
Optical fiber clamping joint is caught in printed board again, made in back-off 23 and the printed board of the cantilever 22 of the fixture 2 of optical fiber clamping joint
Corresponding block button hole is interlocked, so that optical fiber clamping joint is fixed in printed board, consolidating for optical fiber clamping joint is clicked during dismounting
Optical fiber clamping joint can just be unloaded from printed board by determining the cantilever 22 of part 2, easy to operate.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
Be appreciated that without departing from the principles and spirit of the present invention can to these embodiments carry out it is a variety of change, modification,
Replace and modification, the scope of the present invention is limited by appended claims and its equivalency range.
