Description
Technical field
The utility model relates to a kind of optical communication system outdoor base station optical connector.
Background technology
At present, the optical communication system outdoor base station with the product structure mode that optical connector extensively adopts is: on international standard connector LC and MTRJ basis, be made into the outdoor optical cable connector that satisfies outdoor light path interconnection through the metal parts that increases some functions that prevent to drench with rain outside these connector plugs and adapter.Owing in this connector, used LC, MTRJ plug and adapter, must look after on the one hand the shape of the plug of use and adapter and volume etc., the temperature range of LC and MTRJ connector also narrow (25 ℃～70 ℃) on the other hand, this makes that the outdoor optical cable connector volume ratio of design is bigger, and the usable range of product also is subjected to certain limitation.
Summary of the invention
The purpose of this utility model provides the optical communication system outdoor base station optical connector that a kind of temperature range is wide, volume is little.
The technical solution of the utility model: plug is made up of plug spare and plug annex two parts, and plug is fixed on the contact pin parts in porcelain bushing and the plug in the spline housing of plug by plug insulator, pressing plate and back-up ring; The sleeve of plug annex links together by holding screw, cushion rubber and spline housing; Pressure welding case and interior cover are fixed spinning synthetic fibre in the optical cable; Back-up ring and sealing nut compress rubber sleeve.Contact pin parts in the plug are made up of ceramic contact pin, sleeve, ring flange, spring, back cover and optical fiber, and ceramic contact pin one end is fixed on the ring flange and places sleeve, and spring is fixed in ring flange and back inner room, and optical fiber is connected with ceramic contact pin by the back cover is fixing.
Socket is fixed on the contact pin parts in the socket in the square plate housing of socket by socket insulator, pressing plate and back-up ring.
Effect of the present utility model is, because optical connector main problem in outdoor application is sealing, the utility model adopts interfacial seal to add the tightening screw lock in plug between sleeve and the plug, not only can realize sealing, also guarantee the firm connection between annex and the plug simultaneously; The fixing tensile materials in the optical cable of cover and pressure welding case in adopting between plug and the optical cable, and sleeve afterbody employing cable joint-box, pressing plate and sealing nut guarantee between optical cable and the plug annex sealing with firmly be connected; Be provided with dust cap in the plug and socket, dust cap is mainly used in the interior contact pin of protection plug and female part is avoided external environmental and influenced properties of product; Adopt five keys, five groove structures between the plug and socket, both can guarantee blind inserting between the headstock, can prevent the interconnection rotation again; Plug and socket directly adopt radially seal with O ring and the rubber sealing at interface, reach the purpose of two seals; Because narrower LC and the MTRJ connector of serviceability temperature scope no longer in plug and socket, like this, when designing, novel connector construction can optimize and reduce small product size on the one hand, another side adopts temperature range wideer ceramic contact pin, metal flange dish and heatproof greater than 100 ℃ plastics, the working temperature that can guarantee product reach-40 ℃～more than+80 ℃, be more suitable in outdoor environment, using.

Embodiment
Below the present invention is described in further details.Referring to Fig. 1,2,3,4,5,6 embodiment, the utility model is made up of plug 2 and socket 1.Plug 2 and socket 1 adopt the blind inserting structure of five keys, five grooves, thread connecting mode.
Plug 2 is made up of plug spare 36 and plug annex 37, plug spare 36 is made up of dust cap parts 3, spline housing 4, coupling nut 5, plug insulator 7, porcelain bushing 6, contact pin parts 8, pressing plate 10, back-up ring 12, and plug annex 37 is made up of dust cap parts 3, holding screw 9, pressing plate 10, cushion rubber 11, back-up ring 12, sleeve 13, pressure welding case 14, interior cover 15, sealing nut 16, back-up ring 17, rubber sleeve 18 and optical cable 19.Contact pin parts 8 are made up of ceramic contact pin 30, sleeve 31, ring flange 32, spring 33, back cover 34 and optical fiber 35.Dust cap parts 3 are mainly used in the protection of plug 2 front end parts and prevent dust; plug spare 35 is working portions of this optical connector; plug annex 37 is mainly used in fixedlying connected of plug 2 and optical cable 19; guarantee sealing between optical cable 19 and the plug 2; a plug 2 is more suitable in outdoor application, and optical cable 19 is mainly used in other optical cable, device and equipment etc. and is connected.The benefit that plug dust cap parts 3 are fixed on the optical connector plug 2 is to lose when avoiding connector to use.
Socket 1 is made up of dust cap parts 20, square plate housing 21, O shape circle 22, cushion rubber 23, square plate rubber cushion 24, socket insulator 25, contact pin parts 26, pressing plate 27, back-up ring 28 and optical cable 29.Socket dust cap parts 20 are mainly used in the protection of socket front end part and dustproof, during use the stiff end of socket dust cap parts 20 are fixed near the optical connector socket, and dust cap is lost and influenced the performance of product when avoiding connector to use.Socket 1 is the working portion of this optical connector, and optical cable is mainly used in other optical cable, device and equipment etc. and is connected.
Because this product is used by plug 2 and socket 1 and finishes the entire product function, therefore here the function after plug 2 and socket 1 interconnection is introduced.Owing between socket 1 and the equipment seal gasket 24 is installed, therefore can guarantee water-tight between socket 1 and the equipment, we can see by Fig. 2: adopt between plug spare 36 and the plug annex 37 to be threaded, and it is fixing with holding screw 9, between plug spare 36 and plug annex 37, O-ring seal 11 is arranged, therefore not only fixed between plug spare 36 and the plug annex 37, and can reach the purpose of waterproof sealing, between plug annex 37 and optical cable 19, adopt rubber sleeve 18 that optical cable 19 and plug annex 37 are sealed, also can realize waterproof sealing; When plug 2 and socket 1 plug together, contact pin parts 26 in the socket 1 enter the porcelain bushing 6 in the plug 2 and dock with ceramic contact pin 30, because the length sum of contact pin parts 26 and ceramic contact pin 30 is bigger with length after socket 1 is connected than plug 2, therefore contact pin parts 26 will compress ceramic contact pin 30, ceramic contact pin 30 retreats and compression spring 33, make ceramic contact pin 30 obtain one constant in relay, thereby guarantee the reliable connection of plug 2 and socket 1 light path; Owing between plug 2 housings and socket 1 housing, adopt O shape circle 22 sealings radially, and between plug 2 and socket 1 interface, adopt cushion rubber 23 sealings, can play the double seal effect, guarantee outdoor long-term use.Do not influence properties of product for guaranteeing that product repeatedly uses, on plug and socket, disposed dust cap 3,20 respectively, when plug and socket when inserting, dust cap 3 and 20 also can be interconnected, can avoid the ceramic contact pin 8,26 in dust cap secondary pollution plug or the socket and cause the decline of properties of product.
