Abstract
The invention relates to a device for concentrated switch connection of machine cabinets of machine rooms of China telecom, China mobile and Unicom, and discloses a linked connecting plug of a single-core optical fiber. The linked connecting plug comprises a tail sleeve sleeved on the optical fiber, wherein a pull handle is connected with a pressure plate; the pressure plate is connected with an inner shell of the plug; a core inserting seat is arranged inside the inner shell of the plug; a spring is sleeved at one end of the core inserting seat and is arranged inside a spring seat; the spring seat is fixed at the end part of the inner shell of the plug; one end of a middle sleeve of an adapter is connected with the core inserting seat, and the other end of the middle sleeve of the adapter is connected with an inner sleeve; the tail part of the inner sleeve penetrates into an optical fiber cable; an outer sleeve is sleeved outside the optical fiber cable; and the tail sleeve wraps the middle sleeve, the inner sleeve and the outer sleeve of the adapter. The linked connecting plug is low in cost, can be matched with the existing device, and can improve the capacity of the machine room with the same size as the like product.
Description
Technical field
The present invention relates to the device that the machine room rack of telecommunications, movement, UNICOM concentrates conversion to connect, be specifically related to a kind of single-core fiber plug that is connected.
Background technology
Three major companies of existing domestic telecommunication, movement, UNICOM adopt the coupling arrangement of single core list adapter to carry out signal conversion, and single core list is joined and existed volume large, can't expand jumbo shortcoming with the rack of volume.The external product that adopts West Europe, Japan to produce although can reduce volume, adopt φ 1.5mm lock pin, and this coupling arrangement cost is high, can't mate with domestic existing equipment simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of single-core fiber plug that is connected, cost is low, can mate with existing equipment, can with the situation of like product equal volume under, improve the machine room capacity.
In order to achieve the above object, the present invention has following technical scheme:
A kind of single-core fiber of the present invention plug that is connected, comprise the tail cover that is enclosed within on the optical fiber, pull handle is connected with pressing plate, pressing plate is connected with the plug inner casing, the lock pin seat is positioned within the plug inner casing, end cover at the lock pin seat has spring, this spring is positioned at spring base, spring base is fixed on the end of plug inner casing, one end of adapter intermediate sleeve is connected with the lock pin seat, and the other end of adapter intermediate sleeve is connected with the inner sleeve, and the afterbody of inner sleeve penetrates in the optical fiber skin cable, overcoat is enclosed within outside the optical fiber skin cable, and the tail cover is wrapped in adapter intermediate sleeve, inner sleeve, puts outward.
Wherein, described lock pin seat is the lock pin seat that can insert φ 2.5mm lock pin.
The invention has the advantages that:
1. the present invention can utilize the part of domestic maturation, can mate with domestic existing equipment, so cost is low, install, and debugging, easy to maintenance.
2. the present invention has reduced volume, can with the situation of like product equal volume under, improve the machine room capacity.
When 3, the present invention uses, as long as gently lift handle, just can pull the plug out of the socket, solve the problem that a lot of plug close-packed arrays in the rack are extracted inconvenience.
4, because the present invention is provided with spring and spring base, the disconnected fibre of optical fiber can occur in use, or affect the performance of optical fiber.

Embodiment
Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
Referring to Fig. 1～14, a kind of single-core fiber of the present invention plug that is connected, by plug inner casing 1-1, can insert the lock pin seat 1-2 of φ 2.5mm lock pin, pressing plate 1-3, pull handle 1-4, spring 1-5, spring base 1-6, adapter intermediate sleeve 1-7, inner sleeve 1-8, overcoat 1-9, tail cover 1-10, optical fiber 1-11 forms, wherein, pull handle is connected with pressing plate, pressing plate is connected with the plug inner casing, the lock pin seat is positioned within the plug inner casing, end cover at the lock pin seat has spring, this spring is positioned at spring base, spring base is fixed on the end of plug inner casing, one end of adapter intermediate sleeve is connected with the lock pin seat, and the other end of adapter intermediate sleeve is connected with the inner sleeve, and the afterbody of inner sleeve penetrates in the optical fiber skin cable, overcoat is enclosed within outside the optical fiber skin cable, and the tail cover is wrapped in the adapter intermediate sleeve, inner sleeve, put outward.
The present invention by plug inner casing 1-1, lock pin seat 1-2, pressing plate 1-3, pull handle 1-4, spring 1-5, spring base 1-6 totally six parts be combined in order semi-manufacture one, see Figure 12.By adapter intermediate sleeve 1-7, inner sleeve 1-8, overcoat 1-9 totally three parts form in order semi-manufacture two, see Figure 13.Semi-manufacture two are pressed into semi-manufacture one, make semi-manufacture two be fastened on the lock pin seat 1-2 afterbody of semi-manufacture one the inside.Be that adapter intermediate sleeve endoporus is connected with lock pin seat afterbody is peripheral.In use the lock pin head is when the interior compression, and whole optical cable and then retreats and can not form bending and disconnected fibre or affect optical fiber property.
As mentioned above, just can realize comparatively fully the present invention.The above only is comparatively reasonably embodiment of the present invention, and protection scope of the present invention includes but are not limited to: this, and any the including based on unsubstantiality sex change change on the technical solution of the present invention of those skilled in the art the present invention includes within the scope.
