Description
Technical field
The utility model relates to LC fiber adapter accessory, a kind of specifically metal joint seat that is used for fiber adapter.
Background technology
In the existing communication technical field, fiber adapter is used for communication facilities in a large number, and fiber adapter has two kinds of fiber modes, vertical machine card plate fiber and dumper card plate fiber.
The fiber adapter of vertical machine card plate fiber requires before the machine card plate bigger fiber space is arranged, raising along with system complex degree and integrated level, the preceding available space of machine dish is very limited in the equipment, adopt the fiber adapter of vertical machine card plate fiber often to cause connector tail optical fiber and frame door to interfere and can not close the door, if it is then more impossible to install attenuator additional before fiber adapter.
The fiber adapter of dumper card plate fiber can solve the problem of above-mentioned existence, but the fiber adapter of existing dumper card plate fiber need solve the problem of machine dish electromagnetic screen and dust tightness.In order to solve the problem of electromagnetic screen and dust tightness, each opening part of the pedestal that tilts all has an outer, pedestal is inwardly packed into by machine card plate outside, the outer is stuck in the outside surface of machine card plate, there is conductive fabric electrically to contact on it, forms projection, influence attractive in appearance at machine card plate outside surface with machine card plate, anti-dust performance is good inadequately, is unfavorable at machine dish outside surface pad pasting.
The utility model content
At the defective that exists in the prior art, the purpose of this utility model is to provide a kind of metal joint seat that is used for fiber adapter, simple in structure, with low cost, can install in the fiber adapter plinth of machine card plate the fiber adapter of vertical fiber is oblique, capability of electromagnetic shielding is good, easy-to-use, dust tightness is preferable, make the machine panel surface smooth, both artistic and practical from installed inside.
For reaching above purpose, the technical scheme that the utility model is taked is:
A kind of metal joint seat that is used for fiber adapter, it is characterized in that: metal joint seat 1 comprises some stacked inner chambers 12 up and down, each inner chamber 12 comprises upper wall 21 connected vertically and lower wall 22, the left and right sides of upper wall 21 and lower wall 22 is provided with sidewall 23, and upper wall 21 is provided with the mounting hole adaptive with fiber adapter; Metal joint seat 1 left and right sides side is provided with conductive fabric liner 9, and what upper wall 21 front ends tilted is connected with metal joint seat 1 side, and the angle of inclination is 40～60 °.
On the basis of technique scheme, the front of the top and bottom of metal joint seat 1 is provided with first fixed orifice 10.
On the basis of technique scheme, two sides are provided with second fixed orifice 11 about the top and bottom of metal joint seat 1.
The metal joint seat that is used for fiber adapter described in the utility model, simple in structure, with low cost, can install in the fiber adapter plinth of machine card plate the fiber adapter of vertical fiber is oblique, capability of electromagnetic shielding is good, easy-to-use, dust tightness is preferable, make the machine panel surface smooth, both artistic and practical from installed inside.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 4, the metal joint seat that is used for fiber adapter described in the utility model, comprise some stacked inner chambers 12 up and down, each inner chamber 12 comprises upper wall 21 connected vertically and lower wall 22, the left and right sides of upper wall 21 and lower wall 22 is provided with sidewall 23, and upper wall 21 is provided with the mounting hole adaptive with fiber adapter; Metal joint seat 1 left and right sides side is provided with conductive fabric liner 9, and what upper wall 21 front ends tilted is connected with metal joint seat 1 side, and the angle of inclination is 40～60 °.
On the basis of technique scheme, the front of the top and bottom of metal joint seat 1 is provided with first fixed orifice 10.
On the basis of technique scheme, two sides are provided with second fixed orifice 11 about the top and bottom of metal joint seat 1.
The fixed form of the utility model in the machine dish has two kinds (optional one or uses simultaneously):
1,, as shown in Figure 1, fixing with machine card plate 4 with screw 6 by first fixed orifice 10;
2,, as shown in Figure 3, fixing with machine dish pcb board 5 with screw 7 by second fixed orifice 11.
During use, fiber adapter 2 is inserted in the mounting hole of upper walls 21, be 40～60 ° of angles between fiber adapter 2 and machine card plate, realized installing in the purpose of machine card plate the fiber adapter of vertical fiber is oblique.
The beneficial effects of the utility model are:
1, by metal joint seat is set, so that the fiber adapter Way out is consistent with plinth lumen openings direction, because lumen openings direction and machine card plate tilt, therefore after being installed in fiber adapter on the metal joint seat, fiber adapter also tilts with machine card plate, has realized the oblique of fiber adapter fiber;
2, simple in structure, the plug of fiber adapter 2 and LC optical fiber is easy, cost of manufacture is low and aesthetic appearance good;
3, increased space between fiber adapter fiber and the frame door, shown in Fig. 1～3, can increase the fiber length of the LC joints of optical fibre 3 tail optical fibers, also be convenient to configuration and be connected other device;
4, conductive fabric liner 9 can guarantee that the machine dish has good capability of electromagnetic shielding in the fiber adapter exit;
5, conductive fabric liner 9 can guarantee the seal in the fiber adapter exit of machine dish, thereby has good dust-proof effect.
