Abstract
The invention provides a tail end bending-resistant FC connector comprising an inserting core, an internal shell, a tail handle, an external shell, a spring, a rear shell and a sheath. The inserting core, the internal shell, the tail handle and the rear shell are connected in turn. The spring is arranged between the tail handle and the rear shell. One end of the external shell sleeves the internal shell, and the other end of the external shell sleeves the sheath. The sheath and the rear shell are clamped. The tail end bending-resistant FC connector also comprises an armored pipe which is arranged in the tail handle in a penetrating way. The armored pipe is arranged, one end of the armored pipe penetrates into a tight-buffered optical fiber of an optical cable, and then the tight-buffered optical fiber and the armored pipe penetrate into the tail handle together so that bending-resistant performance of the connector can be greatly enhanced and thus online bending performance can be enhanced.
Description
Technical field
The present invention relates to field of connectors, particularly relate to the counter-bending FC connector of a kind of tail end.
Background technology
The FC connector of current industry, is directly connected optical cable with lock pin, and such anti-bending strength is poor, can not meet the requirement of the online bending property of client.
Summary of the invention
In order to solve the problems of the prior art, the invention provides the counter-bending FC connector of a kind of tail end.
The invention provides the counter-bending FC connector of a kind of tail end, comprise lock pin, inner casing, caudal peduncle, shell, spring, back cover and sheath, described lock pin, inner casing, caudal peduncle, back cover connect successively, described spring is located between described caudal peduncle and described back cover, described shell one end is placed on described inner casing, and the described shell other end is placed on described sheath, described sheath and described back cover clamping, the counter-bending FC connector of this tail end also comprises armour pipe, and described armour pipe is through in described caudal peduncle.
As a further improvement on the present invention, described sheath is interior engraved structure.
As a further improvement on the present invention, described sheath afterbody is provided with line feeder.
As a further improvement on the present invention, described spring one end and described caudal peduncle offset, and the described spring other end and described back cover offset.
As a further improvement on the present invention, described spring is volute spring.
As a further improvement on the present invention, also comprise crimp rings, described crimp rings is located between described back cover and described sheath.
As a further improvement on the present invention, described armour pipe is metal armour pipe.
The invention has the beneficial effects as follows: armour pipe is set, one end of armour pipe is penetrated on the tight tube fiber of optical cable, then tight tube fiber and armour pipe are penetrated in caudal peduncle together, greatly can strengthen the bending resistance of connector like this, thus improve online bending property.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the counter-bending FC connector of a kind of tail end of the present invention.
Embodiment
Reference numeral: 1-lock pin 2-inner casing 3-caudal peduncle 4-back cover 5-spring 6-shell 7-sheath 8-crimp rings 9-armour pipe 10-optical cable 11-tight tube fiber.
As shown in Figure 1, the invention discloses the counter-bending FC connector of a kind of tail end, comprise lock pin 1, inner casing 2, caudal peduncle 3, back cover 4, shell 6, spring 5, sheath 7, crimp rings 8 and armour pipe 9, described lock pin 1, inner casing 2, caudal peduncle 3 and back cover 4 connect successively, described lock pin 1 is through in described inner casing 2, described spring 5 is located between described caudal peduncle 3 and described back cover 4, described spring 5 one end peaks at described caudal peduncle 3, the other end peaks in described back cover 4, described caudal peduncle 3 can compress described spring 5, and shell 4 is interior mobile in the rear, described armour pipe 9 one end penetrates on the tight tube fiber 11 of optical cable 10, described armour pipe 9 other end penetrates in described caudal peduncle 3 together with described tight tube fiber 11, described shell 6 one end is placed on outside described inner casing 2, described shell 6 other end is placed on outside described sheath 7, described sheath 7 and the clamping of described back cover 4 tail end, described crimp rings 8 is located between described sheath 7 and described back cover 4.
In the present embodiment, described sheath 7 is interior engraved structure, improves bending resistance.
In the present embodiment, described sheath 7 afterbody is also provided with line feeder, ensure that the stretching resistance of sheath.
In the present embodiment, described spring 5 is volute spring.
In the present embodiment, described armour pipe 9 is metal armour pipe, and described metal armour pipe adopts super flexible stainless steel material, the bending resistance of so better raising connector.
In the present embodiment, the internal diameter of described caudal peduncle 3 is 1.1mm-1.12mm, the external diameter of described armour pipe 9 is 1.03mm-1.05mm, wall thickness is 0.1mm, and by one end of armour pipe 9 is penetrated on the tight tube fiber 11 of optical cable 10, again tight tube fiber 11 and armour pipe 9 are penetrated in caudal peduncle 3 together, and sheath 7 is set to interior engraved structure, line feeder is increased at sheath 7 afterbody, greatly can strengthen the bending resistance of connector tail end like this, thus improve online bending property, thus online pulling force and the bending resistance of client can be met.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
