Multipole electrical socket with earth contact.

factory

The invention relates to a multi-pole electrical socket with earth contact, with a waterproof, from box and Cover existing insulated housing, with a connection » clamp for the earth line.

In the formation of sockets of this type with insulating housing, it is normally not necessary within the Housing an additional connection terminal for the earth conductor. Here, the earth conductor is inserted into the box The cables to be introduced are already carried and can be connected to the in the socket insert provided earth contact socket directly connected »If these sockets are installed in networks without an earth conductor, the must be connected to the socket via the socket device to be connected, a special earth wire is routed to the socket and connected to the earth contact socket to be brought. A socket has become known for this installation, in which a « wall arranged metal angle with a wall penetrating from the outside of the threaded bushing electrically connected and is attached to the wall, with a flexible connector connected to the ground contact socket of the socket on the elbow Lead wire is connected while outside the case

a separate earth wire can be connected to the threaded bushing. However, this training is very complex.

The invention creates a simplification that consists in that the connecting clamp on a side wall dung is attached within the box and the side wall at the level of the clamping surface of the earth conductor has a recess with a knockout wall for the introduction of the earth conductor on «has.

The connecting terminal is useful as a socket terminal at least one clamping hole for the earth conductor and the clamping hole with the recess in the wall of the socket « mating congruent · The recess is formed by counterpressing.

In a further embodiment, the connecting clamp is held in a pocket on the side wall of the box so that it cannot rotate and fastened by means of a fastening element, e.g. a screw «

Another feature is that the connecting clamp on the side wall containing the cable entry has a preference « wise is arranged directly next to the cable entry.

In further training there is a pocket on both sides of the cable entry to accommodate the connecting terminal and a recess. arranged with a break-out wall for the introduction of the earth conductor, one of the fastening member penetrated breakthrough is provided with an optional knockout wall.

The socket is shown in the drawing in one embodiment. It shows:

Fig * 1 is a plan view of the socket with; removed housing cover,

FIG. 2 shows a longitudinal section through the socket and FIG. 3 shows a view of the socket side wall.

A socket insert J> is fastened in the insulating housing made up of socket 1 and cover 2. This carries the sockets 4 for the phase lines and a socket 5 for an earth or protective contact line. 1 shows the connection of a three-wire cable which is inserted into the interior of the socket 1 penetrating the side wall 7 through a cable entry 8 that can be sealed with a sealing collar or screw connection and is connected to the sockets 4 with its line ends. For the connection of a separate ground wire 9, a connecting terminal 10 is arranged inside the socket 1 "This is held in a recess designed as a pocket 11 on the inside of the wall 7 in a torsion-proof manner and by a fastening member 12 designed as a screw that attaches the bottom of the Can 1 penetrates, fastened. The connecting terminal 10 is preferably provided with two clamping bores 13, one of which can receive the ground wire 9 coming from the outside and the other a flexible wire 14 connected to the ground contact socket 5. In the side wall 7, a recess with a breakable wall is provided for the introduction of the earth conductor 9. The recess is formed by counterpressing in such a way that

that on the wall outside a groove 15 from the bottom side of the can 1 and on the inside of the wall a groove 16 is pressed in from the upper edge of the wall 7, the ends of which are towards the Formation of a circular, with a hole 13 covering " The same opening overlap and are separated from one another only by a thin partition 17 that can be broken out are »This wall 17 can be pierced by means of a tool to introduce the earth conductor 9.

The connecting terminal 10 can optionally be arranged on the side walls 7 running parallel to the socket insert 3 or on the upper or lower side wall ¹ J containing the cable entry b. In the example shown, the connecting terminal 10 is arranged directly next to the cable entry 8.

In the illustrated embodiment, a pocket 11 for receiving the connecting terminal 10 and recesses 15, 16 with a breakable wall 17 for the introduction of the earth conductor 9 are provided on both sides of the cable entry ti »There is a recess l8 for the receptacle of the fastening screw 12 is arranged, which is provided at its confluence in the pocket 11 with a wall 19 which can be broken out if necessary. As a result, the socket 1 can also be used for a normal installation in which the earth conductor in the cable is introduced into the socket 1 through the cable entry 8 and no earth connection terminal 10 is required.
