Description

  The present invention relates to a splice unit that is provided in a rack and connects optical fibers.

  The splice unit is attached to the inside of the rack, and an adapter panel to which a plurality of adapters for connecting optical fibers are attached is fixed to the front surface of the case. The adapters provided on the adapter panel are arranged vertically and horizontally, and the adapters connect the optical fibers by inserting connectors provided at the front ends of the optical fibers from both the front and rear sides. A support plate protrudes forward from the lower end of the adapter panel so as to support the optical fiber connected to the adapter so as not to be broken (see, for example, Patent Document 1).

JP 2006-350133 A (FIGS. 1 to 3)

  As described above, the splice unit is provided with the adapter panel arranged vertically and horizontally on the adapter panel. Especially, the adapter provided below has a work space in front of the connection port of the adapter because the bottom surface of the case or the support plate is obstructive. Therefore, it is very difficult to attach and detach the optical fiber connector, and the workability is poor.

  According to the first aspect of the present invention, in the splice unit comprising an adapter panel provided with a plurality of adapters for connecting optical fibers on the front surface of the case, the lower part of the adapter panel is attached to the case. It is characterized by being able to tilt forward by wearing a butterfly.

  According to a second aspect of the present invention, in the splice unit according to the first aspect, the support plate that protrudes forward from the lower part of the adapter panel and supports the optical fiber connected to the adapter is provided at the lower part of the adapter panel. It is characterized by being able to tilt forward by wearing a butterfly.

  According to the first aspect of the present invention, the adapter panel is tilted forward so that the back side connection port of the adapter 4 faces obliquely upward, and the front space of the back side connection port of the adapter provided at the lowest level of the adapter panel. Therefore, it becomes easy to attach and detach the optical fiber from the back side to the adapter provided in the lower part, and the workability is improved.

  According to the invention described in claim 2, in addition to the effect of the invention described in claim 1, the front space of the front side connection port of the adapter provided at the lowermost stage of the adapter panel by tilting the support plate forward. Therefore, it is easy to attach and detach the optical fiber from the front side to the adapter provided below, and the workability is improved.

  The splice unit is an adapter panel provided with a plurality of adapters for connecting optical fibers so that it can be tilted forward by attaching it to the front of the case, and in order to support the optical fibers connected to the adapter from the front, A support plate protruding forward at the lower end is hinged to the adapter panel so that it can be tilted forward.

  A first embodiment of a splice unit according to the present invention will be described with reference to the accompanying drawings of FIGS.

  The splice unit 1 includes a case 2, an adapter panel 5 provided on the front surface of the case 2 and attached with a plurality of adapters 4 for connecting the optical fibers 3, and a support projecting forward from the lower end of the adapter panel 5. It consists of a plate 6.

  The case 2 is formed by a bottom face portion 2a and left and right side face parts 2b in a substantially U-shape with the front surface, top face, and back face open, and a rack (not shown) is provided on the front edge of the left and right side face parts 2b in the left and right outer directions. An attachment piece 2c for attaching to the projection is provided. The left and right front ends of the case 2 are formed with L-shaped case-side bent portions 2d for attaching the adapter panel 5. A lid plate (not shown) is attached to the upper surface of the case 2.

  The adapter panel 5 is arranged such that the adapters 4 are aligned vertically and horizontally, and the adapter 4 is configured to connect the optical fibers by inserting a connector 3a provided at the front end of the optical fiber 3 from both the front and rear sides. The adapter panel 5 has L-shaped panel-side bent portions 5a that coincide with the case-side bent portions 2d of the case 2 at both left and right ends, and the panel-side bent portions 5a are connected to the case-side bent portions 2d by hinges 7. It is attached so that it can be tilted forward. Further, a latch 8 is provided at the upper end of the panel side bent portion 5a, and can be engaged and disengaged with a latch hole 2e formed in the case side bent portion 2d.

  The support plate 6 is formed in a substantially U shape by the bottom plate portion 6a and the left and right side plate portions 6b, and the lower end portion of the left and right side plate portion 6b is shared with the hinge 7 of the adapter panel 5 to the case side bent portion 2d of the case 2. It is attached so that it can be tilted forward. The upper edge of the hinge 7 of the left right side plate portion 6b is bent outwardly in a bent portion 6c, and a latch 9 is provided in the bent portion 6c so as to be formed in the panel side bent portion 5a of the adapter panel 5. The latch hole 5b can be engaged and disengaged. The left and right side plate portions 6b are provided with substantially U-shaped cutouts 6d for pulling out the optical fibers 3 connected to the adapter 4 to the left and right outer sides, and the cutouts 6d are placed so as not to damage the drawn optical fibers 3. The portion 6e is bent outward.

  The splice unit 1 formed in this manner has the mounting piece 2c of the case 2 brought into contact with the mount angle of the rack from the front side, and a screw is inserted into the hole of the mounting piece 2c to be fastened and fixed to the mount angle. Mounted in the rack. In the splice unit 1 thus mounted in the rack, in order to attach or detach the optical fiber 3 to the adapter 4 of the adapter panel 5 from the back side, the latch 8 of the adapter panel 5 is pulled toward the front side to release the engagement with the case 2. Then, the adapter panel 5 is tilted forward by rotating the hinge 7 around the fulcrum. The adapter panel 5 is held in a forward tilted posture by the lower end of the panel side bent portion 5 a coming into contact with the case side bent portion 2 d of the case 2. By tilting the adapter panel 5 forward, the back side connection port of the adapter 4 is directed obliquely upward, and the front space of the back side connection port of the adapter 4 provided at the lowermost stage of the adapter panel 5 is widened. The optical fiber 3 can be easily attached to and detached from the adapter 4 provided. After the connection is completed, the adapter panel 5 is rotated so as to be vertical, the panel side bent portion 5a is pressed against the case side bent portion 2d, and the latch 8 is pushed into the latch hole 2e. Engage and fix.

  In order to attach / detach the optical fiber 3 to / from the adapter 4 of the adapter panel 5 from the front side, the adapter panel 5 is fixed vertically to the case 2, and the latch 9 of the support plate 6 is pulled to engage with the adapter panel 5. This is performed in a state in which the support plate 6 is tilted forward by rotating the hinge 7 around the fulcrum. Note that the support plate 6 is held in a forward inclined posture by the lower end of the bent portion 6 c coming into contact with the panel-side bent portion 5 a of the adapter panel 5. By tilting the support plate 6 forward, the front space of the front-side connection port of the adapter 4 provided at the lowermost stage of the adapter panel 5 is widened. Therefore, the optical fiber 3 is particularly attached to and detached from the adapter 4 provided below. It becomes easy. After the work is completed, the front end of the support plate 6 is lifted and rotated, the bent portion 6c is pressed against the panel side bent portion 5a, and the latch 9 is pushed in, thereby engaging the latch 9 with the latch hole 5b. And fix.

  The position and structure of the hinge 7 for tilting the adapter panel 5 and the support plate 6 forward, and the structure for fixing the adapter panel 5 and the support plate 6 to the fixing position are not limited, and can be changed as appropriate.

It is a perspective view which shows the splice unit which concerns on this invention. It is a side view of a splice unit. It is a perspective view from the back side of the state which inclined the adapter panel forward. It is a side view of the state which inclined the adapter panel forward.
