DETAILED DESCRIPTION

(7) The invention concerns a marker-holder system for a terminal block, comprising a marker-holder device 1 for a terminal block 11 and a fastener 12 disposed on the terminal block 11.

(8) FIG. 1 is a perspective view of a linear arrangement 10 comprising ten marker-holder devices 1 aligned edge-to-edge and made, in one piece, of an electrically insulating material. Each marker-holder device 1 is detachable from the linear arrangement 10, and can be used individually, independently of the other marker-holder devices 1 of the arrangement 10.

(9) Each device is intended to be fastened to an electrical terminal block 11. FIGS. 4 and 5 show a set of ten terminal blocks 11, mounted side by side. Each terminal block 11 can be detached from the set and can be used individually, independently of the other terminal blocks of the set. Each terminal block comprises one part made of insulating material.

(10) At least one fastener 12 is disposed on the insulating material part of each terminal block, as shown in FIG. 5. The fastener 12 is intended to receive forcibly a complementary element 3 located at one of the ends 2a, 2b of the marker-holder device. The marker-holder device 1 has a central part of a substantially parallelepipedal shape, elongated according to a direction of extension. The complementary element 3 is, in the embodiment described here, an elongate cylinder in a direction transverse to the direction of extension of the marker-holder device 1. The cylinder is maintained between two extensions of the central part of the marker-holder device, located at one end 2a in the direction of extension and/or at the other end 2b in the direction opposite to the direction of extension of the marker-holder device.

(11) The central part of the marker-holder 1 has two opposite faces 5, 6 onto which can be added a marker or a label bearing an appropriate reference.

(12) When the cylindrical element 3, located at the end 2a or 2b of the marker-holder device 1, is forcibly inserted into a fastener 12 disposed on the terminal block 11, then the marker-holder device 1 is attached, in a removable manner, to the terminal block 11, and is movable in rotation about the axis of the cylindrical element 3, so that it can take a first position in which a first face 5 of the marker-holder device 1 is oriented towards the terminal block 11 and a second face 6 of the marker-holder device 1 is oriented in a direction opposite to the terminal block, or a second position in which the first face 5 of the marker-holder device 1 is oriented in a direction opposite to the terminal block and the second face 6 of the marker-holder device 1 is oriented towards the terminal block 11. It is thus possible to use in a simple manner the same device for bearing a different marker on the first face and on the second face. These two markers will be alternately visible in the first or in the second position.

(13) According to a second use of the marker-holder device 1, this device can close, in one of its two positions, an opening 14 arranged in the terminal block 11, and when the opening 14 is to receive, in accordance with its destination, a connecting element or a withdrawable connector 13, the marker-holder device 1 can open, as illustrated in FIG. 5, to let pass the connecting element or the withdrawable connector 13, then close again to cover and protect this connecting element or this withdrawable connector 13 after its insertion into the opening 14, as illustrated in FIG. 4.

(14) The marker-holder device 1 illustrated in FIG. 1 can be fastened by these two ends 2a and 2b simultaneously on the terminal block 11, provided that the latter is equipped with two fasteners 12 corresponding to the cylindrical elements 3 located at each end 2a and 2b. In this case, the marker-holder device 1 is no longer movable in rotation.

(15) According to a variant of the marker-holder device 1, this device includes, at its central part, a thinned portion 4 located between the two ends 2a and 2b of the marker-holder device 1, so that the marker-holder device 1 is divisible in two parts, each part can then become a marker-holder device, however with a dimension according to the direction of extension which is shorter than that of the initial marker-holder device 1. Each marker-holder device resulting from this separation into two parts is then provided with a single end that can be fastened to the terminal block according to a rotary connection similar to that described above for the marker-holder device 1 according to the first embodiment.

(16) As indicated in FIGS. 4 and 5, the marker-holder devices can be used not only individually but also grouped according to linear arrangements 10 that can gather an undetermined number of marker-holder devices 1, and intended to be mounted on as many corresponding terminal blocks gathered together. The invention therefore also concerns an arrangement 10 of a plurality of marker-holder systems according to any of the variants described above, for a plurality of terminal blocks, each marker-holder system of the plurality of marker-holder systems comprising a marker-holder device 1 and the fastener(s) 12 configured to be disposed on a corresponding terminal block 11 of the plurality of terminal blocks; the marker-holder devices 1 of the plurality of marker-holder systems being aligned according to a direction transverse to the direction of extension of one of the devices, each marker-holder device 1 being securely attached to the neighboring marker-holder devices 1 located on either side of this marker holder device 1; the fastener(s) 12 disposed on the terminal block being correspondingly aligned with the alignment of the ends 2a or ends 2b of the marker-holder devices 1.
