Embodiment:
See also Fig. 2 and shown in Figure 3, the utility model light receiving and transmitting submodule comprises with socket 20 accommodates pipe 21; One optical fiber retaining piece 30 is arranged at this front end of accommodating pipe 21; One sleeve 40 is arranged in this and accommodates pipe 21 and optical fiber retaining piece 30; One headgear 50 is arranged in this sleeve 40 and optical fiber retaining piece 30; Reach an optical fiber 54 and be inserted in headgear 50, it is arranged in this optical fiber retaining piece 30 and the headgear 50 from this optical fiber retaining piece 30.
As shown in Figure 4; This inside of accommodating pipe 21 has the part length of this optical fiber retaining piece 30 of one first accepting hole, 22 receivabilities; The part length of this sleeve 40 of one second accepting hole, 23 receivabilities; Reach a connecting hole 24 and be positioned at the rear end of accommodating pipe 21, can supply a fibre-optical splice to insert and link, must make the transmission of light signal.This first accepting hole 22 is positioned at the front end of accommodating pipe 21, and its diameter dimension is bigger than second accepting hole 23.The diameter dimension of this second accepting hole 23 is bigger than this connecting hole 24, and this connecting hole 24 is positioned at this rear end of accommodating pipe 21.
As shown in Figure 5, this optical fiber retaining piece 30 has an interface portion 31 and a tilt head 32.This interface portion 31 defines one the 3rd accepting hole 33, and its diameter dimension can be in order to admit the part length of this sleeve 40, and reaching one the 4th accepting hole 34 can be in order to admit the part length of this headgear 50.
This tilt head 32 defines an angling hole 35 and a zone of transition 39; This zone of transition 39 communicates with this angling hole 35; And near the 4th accepting hole 34, the front end (inclination) of its this optical fiber 54 of diameter dimension receivability partly and makes the luminous signal of luminescence component be coupled to optical fiber 54.This zone of transition 39 can make optical fiber 54 gradual changes, and optical fiber 54 when angling hole 35 inserts, can slowly be turned in this zone of transition 39, makes bending radius become big.This tilt head 32 is formed with first and second annular shoulder 36,37.
The front end face of this tilt head 32 is an inclined-plane 38, can prevent that reflected light from directly injecting in luminescence component, causes luminescence component to receive interference of noise.
As shown in Figure 6, the inside of this sleeve 40 have a through hole 41 can in order to the front end of admitting this fibre-optical splice partly and the rear end of this headgear 50 partly.
As shown in Figure 7, this headgear 50 has rightabout forward and backward facial 51,52, and a perforation 53 extends axially in this forward and backward facial 51,52.The rear end of this this optical fiber 54 of 53 receivabilities of boring a hole (not tilting) partly.
The front end of this perforation 53 has a conical optic fibre guide hole 55; When optical fiber 54 when zone of transition 39 extends to optic fibre guide hole 55, the top that can make optical fiber 54 gets in this perforation 53 along the internal face in optic fibre guide hole 55.
Because the tilt head 32 of optical fiber retaining piece 30 is to utilize the metal powder mode of penetrating into and the interface portion 31 formula structure that is combined into one, reaches and significantly reduce production costs and can reduce the loss of incident light signal; And the front end of this optical fiber 54 partly is arranged in the angling hole 35 of this tilt head 32 with the inclination mode, makes the incident direction of light exit direction and light coaxial, to satisfy the computing formula of light beam shooting angle; So; The light signal that luminescence component 60 is sent can be assembled in the optical fiber 54 that is coupled to this tilt head 32 in a large number, reduces coupling loss by this, significantly to improve light coupling efficient; As shown in Figure 8; Because of tilt head 32 θ 2 angles that tilt, be coaxial in order to the incident direction of the light exit direction of correcting this tilt head 32 and the luminous signal of luminescence component 60, can obtain the light coupling efficient of the best.
The above content is merely the explanation of this case one preferred embodiment, but not in order to the utility model is done any restriction.The people of any this skill of being familiar with possibly utilize and take off that technology contents changes or be modified to other embodiment and the spirit and the category that still do not break away from the utility model, and the utility model scope is only by following claim restriction.
