Embodiment
The present invention is further described with reference to the accompanying drawings and examples：
As shown in embodiment in Fig. 1 and Fig. 2, this pair of ceramic insertion core optical fiber splicing device, it includes, and lock pin is first 1, inserted block 2,
The inserted block 2 for cylindrical shape, the both ends of the inserted block 2 are machined with coaxial mounting hole 21 respectively, the mounting hole 21 it
Between by coaxial location hole 22 be connected, 22 size of location hole is correspondings with optical fiber, 22 diameter of location hole less than install
21 diameter of hole；Connect between the location hole 22 and mounting hole 21 by taper hole, described first 1 one end of lock pin is processed into and the peace
21 corresponding cylindrical shape of hole is filled, the outer end of first 1 cylindrical shape of lock pin is designed with cone corresponding with the taper hole size
Forming head, the axial location of first 1 cylindrical shape of lock pin were machined with line micropore 11, and described cross in line micropore 11 is incorporated with optical fiber
3, the optical fiber 3 inside lock pin first 1 is stretched out through the line micropore 11 of crossing from taper cephalic par；When the first 1 cylindrical end insertion institute of lock pin
When stating in the mounting hole 21 of inserted block 2, the conical bore of the nose cone and the inserted block 2 of the lock pin first 1 mutually assembles, and stretches out conical head
The optical fiber 3 of end is stretched into the location hole 22.
Double ceramic insertion core optical fiber splicing devices include two lock pin heads, which is mainly used to connect two sections of optical fiber 3
Connect, when specifically used, two sections of optical fiber 3 are inserted into the optical fiber micropore 11 of two lock pins first 1 respectively, then by lock pin
First 1 front end column part is inserted into the mounting hole 21 of the inserted block 2 so that two sections of optical fiber 3 for stretching out line micropore 11 are distinguished
The both sides of the location hole 22 are inserted into, ensure the centering of two sections of optical fiber 3 by the size and linear structure of location hole 22, thus
It can easily realize the positioning of two sections of optical fiber 3.The device realizes pair of two sections of optical fiber by the location hole 22 among inserted block
In, the positioning of line micropore 11 and location hole 22 was realized by the conical head of the taper hole in inserted block 2 and lock pin first 1, and it is micro- to cross line
As long as the location fit of hole 11 and location hole 22 ensures so that may be inserted into the location hole 22 through the optical fiber 3 for crossing line micropore 11
Can.Only need precisely to ensure that the straightness of the location hole 22 can realize that optical fiber 3 connects in the apparatus, significantly
The processing request of part is reduced, improves the connection effect of optical fiber 3.
In specific design, when the nose cone of the lock pin first 1 is inserted into the conical bore of the inserted block 2, the lock pin first 1
Nose cone outer end and the location hole 22 between have 0.2mm~2mm gap.Due to the size of common 3 outside diameter of optical fiber
Generally in 0.125mm or so, when the gap between the nose cone outer end of lock pin described in optical fiber first 1 and the location hole 22 is larger
When, optical fiber 3 is inserted into the location hole, and when the gap is smaller, it is necessary to assure the location hole 22 and the line excessively are micro-
The concentricity in hole 11 just can be with when the gap is 0.2mm~2mm, cost is the most economical.
In the specific implementation, as shown in Fig. 1 and Fig. 3, Fig. 4, the left and right directions point of the cylindrical part of the lock pin first 1
For inside and outside two sections, the first 1 inner segment diameter of lock pin is less than outer section of diameter, and the O of annular is machined with first 1 inner segment of lock pin is cylindrical
Type groove 12, is equipped with O type circles in the O-shaped groove 12.The O-ring is with being that mounting hole is slidingly sealed assembling.It can so ensure
Optical fiber 3 inside the inserted block 2 is isolated from the outside completely, is not easy into water, will not be subject to the dust pollution in the external world.
As depicted in figs. 1 and 2, the location hole 22 of the inserted block 2 is horizontal positioned, and the top of the location hole 22 is machined with
Vertical slot 23,23 lower part of slot are connected with 22 top of location hole, and inserted sheet 24, institute are equipped with the slot 23
State 24 top of inserted sheet and stretch out slot 23.When the inserted sheet 24 extends downwardly, left and right can be stretched into the optical fiber 3 of location hole 22
Lower part is pressed on, the location hole 22 is processed as circular micropore, and line micropore 11, the mistake were inserted into for the ease of the optical fiber 3
The diameter of line micropore 11 have to be larger than the fibre external diameters, so that left and right optical fiber 3 may have larger mistake in docking
Difference, and the inserted sheet 24 is inserted into the top of the location hole 22, and left and right optical fiber 3 is pressed on to the lower part of the location hole 22, makes
Optical fiber 3 can improve the connection precision of optical fiber 3 completely to it.
In specific design, as shown in Figure 3 and Figure 4, the rear portion of the lock pin first 1 is equipped with incoming line module 4, the inlet wire
The upper shaft 41 and lower rotary shaft 42 of two horizontal alignments are equipped with module 4, inlet wire mould is stretched out in one end of the upper shaft 41
Block 4 is equipped with adjusting handle 43, and the other end of the upper shaft 41 is sequentially connected by gear 44 and the lower rotary shaft 42, institute
State shaft 41 and be respectively fitted with the gear 44 being meshed with the end of the lower rotary shaft 42.The upper shaft 41, lower turn
Corresponding wire-crossing wheel 45 up and down is respectively fitted with axis 42, into the optical fiber 3 of the lock pin first 1 from upper and lower two wire-crossing wheels 45
Between pass through, the wire-crossing wheel 45 is made using elastic material, and upper and lower two wire-crossing wheels 45 compress the optical fiber 3.
When twisting the adjusting handle 43, the upper shaft 41 is driven to rotate, it is described since upper shaft passes through engagement
Gear 44 drives lower rotary shaft 42 to reversely rotate, and so described upper shaft 41 can be to bullet with the wire-crossing wheel 45 on the lower rotary shaft 42
Property compress the optical fiber 3 apply frictional force in the same direction, by the rotating to adjusting handle 43 can optical fiber 3 cross line
Realize and move forward and backward in micropore 1 so that the optical fiber in two lock pins first 1 can be entered easily in the location hole.Together
When the optical fiber 3 for stretching out line micropore 11 is lost, in that context it may be convenient to stretching is adjusted after cut-out again.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on, should all be included in the protection scope of the present invention.
