DETAILED DESCRIPTION OF THE INVENTION

(13) The present innovation refers to a cable retaining device (6) comprising two elements, a retaining element (1) and a housing element (2).

(14) The housing element (2) is an elongated body (20) provided with a channel (21), particularly centered on one side of the body (20), said channel (21) extending along the elongated body (20), extending from one end of the body (20) to the other end.

(15) The channel (21) of the housing element (2) has a locking system formed by grooved faces securing the optical drop (3) by locking it.

(16) The retaining element (1) is an elongated body (10) in the form of a rail suitable for receiving the housing (20) of the housing element (2) by insertion into the body (10). The body (10) of the retaining element (1) has a cross-section, substantially in the shape of laid C, with a centralized inner shoulder (11), and the edges (12) of the C have shoulder (121) facing towards the inner part of the elongated body (10), which ensures better attachment of the housing element (2) to the retaining element (1).

(17) The cross-section of the elongated body (10) is complementary to that of the housing (20) of the housing element (2) except for the shoulder (11) which is spaced from the channel (21), forming a space between them when inserting the body (20) of the housing element (2) into the body (10) of the retainer element (1). Said space is sufficiently smaller than the space occupied by an optical drop (3), so as to allow the positioning of the optical drop (3) in the channel (21) and its retention to the device (6) when inserting the housing element (2) in the retaining element (1), being retained in said space, pressed by the shoulder (11) and the channel (21).

(18) Said retaining element (1) comprises a shoulder (13) from its upper face which is provided with a hole (131) used to receive a hook (5) (see FIGS. 9 and 10) which assists in fixing the device (6) on post pulleys or guide rings (not shown).

(19) The retaining element (1) further comprises a housing (14) from the shoulder (13), the housing being provided with an opening (141) (see FIG. 3).

(20) Said housing element (2) further comprises a cable (23) from one end of the body (20), and at the opposite end of the cable (23) there is a enlargement (24) in the form of a diametrical widening of the cable (23) suitable for coupling in the housing (14) through the opening (141) of the retaining element (1), which allows the housing element (2) to be secured to the retaining element (1), facilitating the use of the device (6) when attaching it to an optical drop (3).

(21) The housing element (2) further comprises a protrusion (22) on its lower face which is used to be pressed by the user when inserting and sliding the housing element (2) into the retaining element (1).

(22) For the use of the device (6), as illustrated in FIGS. 9, 10 and 11, the optical drop (3) is firstly positioned in the channel (21) of the housing element (2), after which it is inserted the housing element (2) on the retaining element (1) until the drop (3) is retained within the device (6).

(23) By inserting the housing element (2) into the retaining element (1), with the optical drop (3) in the channel (21), the optical drop (3) is pressed between the grooves of the channel (21) and the shoulder (11) and, in this manner, it is anchored to the device (6) by the pressure applied along and around the entire outer surface of the optical drop (3) retained on the device (6).

(24) As a state of the art device reference, there is the device illustrated in FIG. 1, which is provided with two elements, being a wedge-shaped element (42) which is inserted into a hollow body (41) wherein it was previously positioned the optical drop (3). This device is not suitable, as the optical drop (3) is held in the device by means of protrusions (411) and (421), where the compressive forces are concentrated, which may compromise the signal due to its attenuation. Moreover, this device does not prevent the drop (3) from moving to the sides of the hollow body (41) when inserting the wedge (42), which does not allow proper retention of the optical drop (3), that can become loose.

(25) Having described an example of preferred embodiment, it should be understood that the scope of the present innovation is limited only by the content of the appended claims, including the possible equivalents thereof.
