Abstract
The utility model relates to a protection structure for a fiber connector, relates to a protection structure used for protecting the fiber connector and aims to provide the protection structure with higher safety for the fiber connector. The protection structure for the fiber connector comprises a protection casing (1) and a sealing tail sleeve (2), wherein the sealing tail sleeve (2) is fixedly provided with a safety casing (21), the safety casing (21) is a cylindrical structure, one end of the safety casing (21) contracts like a horn and is fixed on external circumference of the sealing tail sleeve (2), and the other end of the safety casing (21) extends in a direction to connect one end of the protection casing (1). When the sealing tail sleeve (2) is screwed tightly on the protection casing (1), the safety casing (21) is sleeved on the protection casing (1), and one end of the protection casing (1) which is far from the sealing tail sleeve (2) is in the safety casing (21).
Description
Technical field
The utility model relates to a kind of optical cable connection device, particularly relates to a kind of structure for the protection of the joints of optical fibre.
Background technology
The joints of optical fibre are in particular for the connector of indoor plastic material, its physical strength, when the waterproof and dustproof ability can not satisfy request for utilization, adopt usually connector 3 ' outside install a protection housing 1 ' and sealing tail cover 2 ' reinforce additional.As shown in Figure 1, during use, at first connect protected connector 3 ', install then protection housing 1 ', to the protected connector 3 ' physical strength protection is provided, will seal at last tail cover 2 ' be installed to protect housing 1 ' on.O-ring seal is contained in sealing tail cover 2 ' inside; at first with sealed loop-pad protection housing 1 ' near sealing tail cover 2 ' the termination and optical cable 4 ' between; and sealing tail cover 2 ' internal diameter diminish gradually from outside to inside; when sealing tail cover 2 ' be tightened onto protection housing 1 ' when going up; O-ring seal and optical cable 4 ' between can form extrusion structure, thereby will protect housing 1 ' stationkeeping get off.Usually connector 3 ' an end all reach in the casing; protect this moment housing 1 ' an end be close to casing and install; perhaps when connector 3 ' near when not having casing; as long as connector 3 ' both sides respectively install a protection housing 1 ' and sealing tail cover 2 '; like this after installation; protection housing 1 ', sealing tail cover 2 ' and optical cable 4 ' between form an airtight protection structure, make connector 3 ' waterproof and dustproof purpose to reach.
But the existing joints of optical fibre have following defective with the protection structure; as shown in Figure 2; when 3 ' time of needs dismountings connector; if operating personnel's maloperation; can be earlier to protection housing 1 ' dismantle; just the protection housing 1 to away from connector 3 ' direction move; and seal this moment tail cover 2 ' and optical cable 4 ' between remain tightening state; protection housing 1 ' can't freely retreat; like this removal force can through the protected connector 3 of optical cable 4 ' be delivered to ' on, might cause protected connector 3 ' damage.
The utility model content
The technical problems to be solved in the utility model provides the higher joints of optical fibre of a kind of security with protecting structure.
The utility model joints of optical fibre are with protecting structure; comprise protection housing and sealing tail cover; described sealing tail puts and also is fixed with a containment; containment is tubular; one end of containment is horn-like and tightens up on the excircle that is fixed on sealing tail cover, and the other end extends to the direction that connects protection housing one end, when sealing tail cover is tightened on the protection housing; containment is enclosed within on the protection housing, overlaps an end away from the sealing tail on the protection housing and is positioned at containment.
The utility model joints of optical fibre are with the protection structure, and are gapped between the outer wall of the inwall of wherein said containment and protection housing.
The utility model joints of optical fibre are with protection structure difference from prior art that sealing tail in the utility model puts and also are fixed with a containment; containment is tubular; one end of containment is horn-like and tightens up on the excircle that is fixed on sealing tail cover; the other end extends to the direction that connects protection housing one end; when sealing tail cover is tightened on the protection housing; containment is enclosed within on the protection housing; overlap an end away from the sealing tail on the protection housing and be positioned at containment; like this when the dismounting connector; because containment has covered the protection housing; operating personnel can't touch the protection housing; must unscrew sealing tail cover earlier; and tail cover backed out backward, could continue to dismantle and protect housing, finish the dismounting of connector at last.This shows that the utility model security with respect to prior art is higher.
Gapped between the outer wall of the utility model joints of optical fibre with the inwall of containment in the protection structure and protection housing, like this when containment more convenient in meeting when protecting on the housing suit or when protecting housing to resign from office.
The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the location diagram of the joints of optical fibre and protection mechanism in the prior art;
Force diagram when Fig. 2 dismantles for the joints of optical fibre in the prior art and protection structure mistake;
Fig. 3 is the front view of the utility model joints of optical fibre with the protection structure;
Fig. 4 is the utility model joints of optical fibre protection structure scheme of installation.
Embodiment
As shown in Figure 3; the utility model joints of optical fibre comprise protection housing 1 and sealing tail cover 2 with the protection structure; also be fixed with a containment 21 on the described sealing tail cover 2; containment 21 is tubular; one end of containment 21 is horn-like and tightens up on the excircle that is fixed on sealing tail cover 2; the other end extends to the direction that connects protection housing 1 one ends; when sealing tail cover 2 is tightened on the protection housing 1; containment 21 is enclosed within on the protection housing 1, overlaps 2 one ends away from the sealing tail on the protection housing 1 and is positioned at containment 21.In conjunction with Fig. 4 as can be known, gapped between the outer wall of the inwall of described containment 21 and protection housing 1.
When needs carry out reinforcement protection connector 3, will protect housing 1 and sealing tail cover 2 to be docile and obedient order and be through on cable or the optical cable 4, sealing tail cover 2 can adopt corresponding O-ring seal according to the size of hawser external diameter.During installation or removal connector 3, the internal and external relation between the containment 21 of protection housing 1 and sealing tail cover 2 on a kind of space of formation has guaranteed that operating process can not put upside down, and avoids damageeing protected connector 3.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
