Abstract
The utility model discloses an LC male to female type fiber optic attenuator which comprises a front sleeve, a ferrule, a ceramic sleeve, a spring and a stop, wherein the front sleeve is arranged on the front end of the stop in a sleeve manner, and a buckle is arranged at the joint of the front sleeve and the front end of the stop; the ceramic sleeve and the spring are both arranged on the rear end of the ferrule in a sleeve manner; and the ferrule, the ceramic sleeve and the spring are all arranged in an internal cavity formed by the joint of the front sleeve and the stop. A front end dust cap is plug-in mounted on the front end of the front sleeve, and a second dust cap is plug-in mounted on the rear end of the stop. The external contour of the front sleeve is in a shape of square column, and the width of the front sleeve is 6.3mm. The LC male to female type fiber optic attenuator provided by the utility model is compact in structure, closely coordinated, and not easy to be damaged during use.
Description
Technical field
The utility model relates to a kind of LC negative and positive fibre optic attenuator.
Background technology
Existing LC negative and positive fibre optic attenuator, because inner structure is unreasonable, thereby volume is bigger, and combines undertighten between each parts, damages because of loosening easily when LC negative and positive fibre optic attenuator uses.
The utility model content
The utility model technical matters to be solved provides a kind of LC negative and positive fibre optic attenuator, and this LC negative and positive fibre optic attenuator compact conformation cooperates closely, and is in use not fragile.
The technical solution of utility model is following:
A kind of LC negative and positive fibre optic attenuator comprises protheca, lock pin, ceramic sleeve, spring and stop, and protheca is sleeved on the stop front end, and the junction of protheca and stop front end is provided with buckle; Ceramic sleeve and spring all are sleeved on the rear end of lock pin; Lock pin, ceramic sleeve and spring all are arranged in the internal cavities that protheca and stop be connected to form.
The front end of protheca is fitted with the front end dust cap, and the rear end of stop is fitted with second dust cap.
The outline of protheca is a square column type, and the width of protheca is 6.3mm.
Beneficial effect:
The LC negative and positive fibre optic attenuator of the utility model is designed to 6.3mm with the width of protheca, and attenuator and other optic module mate more, and when using the duplex attenuator, the duplex part can be very tight, avoids attenuator to damage.And LC negative and positive fibre optic attenuator is provided with dust cap, can play the good dust-proof effect.In addition, the front end of LC negative and positive fibre optic attenuator is public head, can directly be linked into the adapter of receiving equipment or patch panels.Its rear end is female head, can be connected with wire jumper.
Description of drawings
Fig. 1 is the structural representation (explosive view) of the LC negative and positive fibre optic attenuator of the utility model;
Fig. 2 is the structural representation (front view) after the combination of LC negative and positive fibre optic attenuator;
Fig. 3 is the structural representation (left view) after the combination of LC negative and positive fibre optic attenuator;
Label declaration: 1-front end dust cap, 2-protheca, 3-lock pin, 4-ceramic sleeve, 5-spring, 6-stop, 7-rear end dust cap.
