The handhole of the present invention has one more unit than the known handholes in current use. Its external unit does not have a bottom floor and its sides are (partially) perforated for the removal of any water that may enter, protecting in this way the internal unit which houses the cables and the top of which closes with a flat plate that extends slightly beyond its main body. The bottom floor of the internal unit is conical and ends with a hole which is closed by a conical plug. Both the hole and the plug are threaded. The conical plug has a slot which allows it to be easily opened for the removal of water in the event the unit requires cleaning. The absence of flexible gaskets or metallic screws between the main bodies and plates of the units reduces the total cost of the handhole. ## Claims ### Claim 1 A handhole for outdoor use for the watertight passage of cables, comprising an external unit (1), said external unit (1) comprising side walls with an open bottom and an open top covered with a cap (2) arranged proximally to the surface of the ground and characterised in that it further comprises an internal unit (3) defining a watertight space for the passage of cables, said internal unit (3) comprising a main body with side walls, a closed bottom (5) and an open top covered with a cap (4), said internal unit (3) being smaller than said external unit (1), a space being provided between said external unit (1) and said internal unit (3) whereby any water entering under the cap (2) of the external unit (1) runs downwardly in the space provided between said external unit (1) and said internal unit (3) into the ground, at least one opening being provided in said side walls of the internal unit (3) and at least one opening being provided in said side walls of the external unit (1), said at least one opening of the internal unit (3) being located oppositely said at least one opening of the external unit (1), at least one conduit (7, 8, 9, 10) extending horizontally outwardly said at least one opening of said side walls of the internal unit (3), through a corresponding said at least one opening of said side walls of the external unit (1). ### Claim 2 (depends on 1) A handhole according to claim 1, characterized in that it is being produced in a monoblock construction consisting of said external unit (1) comprising said at least one opening in the side walls thereof and said internal unit (3) comprising said at least one opening in the side walls thereof and said at least one conduit (7, 8, 9, 10) extending horizontally outwardly said at least one opening of said side walls of the internal unit (3) through a corresponding said at least one opening of said side walls of the external unit (1). ### Claim 3 (depends on 1) A handhole according to claim 1, characterized in that said at least one conduit (7, 8, 9, 10) extending horizontally outwardly said at least one opening of said side walls of the internal unit (3) through a corresponding said at least one opening of said side walls of the external unit (1), protrudes exteriorly said external unit (1) with rebated edges having standard commercial dimensions for connection thereof to conduits of a cable network. ### Claim 4 (depends on 1) A handhole according to claim 1, characterized in that the bottom (5) of said internal unit (3) is conical or pyramidal, a threaded hole (6) being provided at the center of said bottom (5) of said internal unit (3), a threaded conical plug (11) being adapted to seal said threaded hole (6). ### Claim 5 (depends on 4) A handhole according to claim 4, characterized in that said threaded plug (11) is provided with a slot-shaped recess allowing unscrewing thereof. ### Claim 6 (depends on 1) A handhole according to claim 1, characterized in that said cap (4) extends marginally beyond the main body of said internal unit (3) thereby enhancing guiding downwardly to the ground water entering under said cap (2) of the external unit (1). ### Claim 7 (depends on 1) A handhole according to claim 1, characterized in that a portion (14) of said side wall of said external unit (1) lying beneath said at least one conduit (7, 8, 9, 10) is perforated thereby enhancing outflow of water entering under said cap (2) of said external unit (1). ### Claim 8 (depends on 1) A handhole according to claim 1, characterized in that said conduits (7, 8, 9, 10) extending outwardly said at least one opening in the side walls of the internal unit (3) and passing through a corresponding opening in the side walls of the external unit (1) are at right angles to each other thereby forming a cross shaped pattern. ### Claim 9 (canceled) ### Claim 10 (depends on 2) A handhole according to claim 2, characterized in that said at least one conduit (7, 8, 9, 10) extending horizontally outwardly said at least one opening of said side walls of the internal unit (3) through a corresponding said at least one opening of said side walls of the external unit (1), protrudes exteriorly said external unit (1) with rebated edges having standard commercial dimensions for connection thereof to conduits of a cable network. ### Claim 11 (depends on 2) A handhole according to claim 2, characterized in that the bottom (5) of said internal unit (3) is conical or pyramidal, a threaded hole (6) being provided at the center of said bottom (5) of said internal unit (3), a threaded conical plug (11) being adapted to seal said threaded hole (6). ### Claim 12 (depends on 11) A handhole according to claim 11, characterized in that said threaded plug (11) is provided with a slot-shaped recess allowing unscrewing thereof. ### Claim at position 13 13-15.
