JP 2004-31439 A

Removing the modular jack from the patch panel is frequently performed during maintenance or when changing the network configuration . There is a case where the assembly work of the patch panel is performed at the construction site.
An object of the present invention is to provide a patch panel in which a cassette from which a modular jack can be attached and detached can be easily attached to and detached from a frame with fingers.

The patch panel in which modular jacks are arranged at high density has a total of 48 modular jacks, and stores 24 rows of modular jacks in two rows (two stages) at a high density. This patch panel has a frame and a frame-shaped face plate attached to the frame. The face plate has a holding latch capable of holding the rear portion of each modular jack. The holding latch extends in an arm shape obliquely upward from the lower wall of the face plate.
When removing the modular jack from the patch panel, the operator needs to push down the arm-shaped holding latch to release the engagement of the holding latch with respect to the modular jack, and pull the modular jack backward.
Since the above-described patch panel accommodates the modular jack at a high density, the operator cannot insert a finger to the position of the holding latch when releasing the engagement of the holding latch with the modular jack. Therefore, the operator pushes down the holding latch downward by inserting a tool such as a flathead screwdriver from the rear or the front into the gap between the frame (lower flange) and the modular jack, and releases the engagement by the holding latch. In this state, it is necessary to remove the modular jack by pulling it behind the modular jack with a finger. For this reason, in the conventional patch panel, both hands are used when removing the modular jack, and there is a problem that the efficiency of the removal work is extremely poor.
A second object of the present invention is to provide a patch panel in which a modular jack can be attached and detached with one finger using a simple structure.

Since the patch panel 11 of the present embodiment can quickly replace individual modular jacks 15, particularly when such a large number of modular jacks 15 are arranged at a high density, the total work is required. Time can be significantly reduced. For this reason, as the number of modular jacks 15 increases, the usefulness thereof increases.

  The finger hook 61 protrudes rearward from the rear end 15A of the main body of the modular jack 15 (see FIGS. 9 and 2). According to this configuration, even in the high-density patch panel 11 in which the modular jacks 15 are arranged in multiple stages in the vertical direction as in the present embodiment, the user can place a finger on the finger hooking portion 61. Accordingly, the modular jack 15 can be quickly attached and detached even in the patch panel 11 having a high density.

  The number of components (cassette 14, modular jack 15, storage unit 51, etc.) shown in the above embodiment is only an example, and can be implemented with appropriate changes according to the implementation format. The attachment position of the lever 52 is also an example, and the lever 52 may be disposed below the frame body 32. In addition, the present invention can be implemented with appropriate modifications without departing from the spirit of the present invention.
