Abstract
The utility model discloses a short contact pin component. The short contact pin component comprises a base, a cover cap, a sleeve and an insertion core, wherein a through hole with steps is formed on the base; the sleeve and the through hole are coaxially connected with each other; the sleeve is in interference fit with the minor diameter end of the through hole; the cover cap is covered in the major diameter end of the through hole, and is coaxially connected with the through hole; one end of the cover cap is propped against the step surfaces of the through hole, and the cover cap is in interference fit with the major diameter end of the through hole; the cover cap is sleeved outside the sleeve, and is in interference fit with the sleeve; and the insertion core is inserted into the sleeve through the minor diameter end of the through hole. In the technical scheme, the sleeve is in interference fit with the cover cap, and the sleeve is in interference fit with the base, so that the sleeve is fixed relative to the base and the cover cap; the insertion core and the sleeve are matched in an inserted and withdrawn manner. Therefore, when an optical fiber connected with the insertion core swings, the alignment of two insertion cores can not be effected, and the stable transmission of optical signals is guaranteed.
Description
Technical field
The utility model relates to a kind of contact pin assembly, particularly a kind of short contact pin assembly that is used to convert the electrical signal to light signal.
Background technology
In optical communication field, the major function of light delivery module is to be light signal with electrical signal conversion, and light signal is converted to a kind of module of electric signal again.For realizing the mutual conversion of electric signal and light signal, generally all need optical fiber is connected with a flexible jumper by a short contact pin assembly, realize the transmission of light signal.
Existing short contact pin modular construction generally as shown in Figure 1, comprise a pedestal 11, pedestal 11 is provided with a through hole with the level, be provided with a block 12 and one sleeve pipe 13 in the bigger diameter end of through hole, block 12 is enclosed within sleeve pipe 13 outsides and its coaxial connection, for flexibly connecting, be to flexibly connect between block 12 and the pedestal 11 between block 12 and the sleeve pipe 13.An end face of block 12, sleeve pipe 13 is resisted against on the step surface of through hole, the internal diameter of sleeve pipe 13 is identical with the internal diameter of through hole miner diameter end, the central shaft of through hole overlaps on the central shaft of sleeve pipe 13 and the pedestal 11, has in the miner diameter end insertion sleeve pipe 13 of lock pin 14 by pedestal of fibre core.
The short contact pin assembly that adopts this structure in use, since the block 12 and sleeve pipe 13 between and between block and the pedestal all be the flexible connection, because sleeve pipe 13 is movable, therefore when swing appears in optical fiber, make two lock pin contrapositions in the sleeve pipe deviation occur easily, make transmission performance stable inadequately, might have influence on the normal use of equipment.
The utility model content
At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provides a kind of short contact pin assembly of new structure, two lock pin contrapositions when this short contact pin assembly swing occurs at optical fiber in the sleeve pipe 13 can not be affected, and guarantee that signal can stable transfer.
For solving the problems of the technologies described above, the utility model adopts following technical scheme.
Technique scheme has following beneficial effect:
A kind of short contact pin assembly, comprise pedestal, block, sleeve pipe and lock pin, described pedestal is provided with the through hole that has step, described sleeve pipe is connected with described through hole is coaxial, the miner diameter end of described sleeve pipe and described through hole is an interference fit, described block in the bigger diameter end of described through hole, described block is connected with described through hole is coaxial, one end of described block is resisted against on the step surface of described through hole, the bigger diameter end of described block and described through hole is an interference fit, described block is enclosed within described jacket exterior, is interference fit between described block and the described sleeve pipe, and described lock pin inserts described sleeve pipe by the miner diameter end of described through hole.
Preferably, described sleeve pipe runs through whole described through hole, and stretches out at the bigger diameter end of described through hole.
Preferably, described block, pedestal are metal material, and described sleeve pipe is a stupalith.
Adopt technique scheme to have following beneficial effect: in this technical scheme, all interference fit between sleeve pipe and block, sleeve pipe and the pedestal, sleeve pipe is relatively fixed with the base and cover cap like this, like this when the lock pin of inserting optical fiber is swung along with optical fiber, can not have influence on the contraposition of lock pin, just can guarantee the stable transfer of signal yet.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
