Description

Socket for an elongated lamp body

The invention relates to a socket for a KmIe oitier double-ended electric lightbulb or fluorescent tube or a socket for receiving such a double c-ndigon luminous element.

It is desirable that one end contact be a double ended electric incandescent lamp or a double-ended electric Fluorescent tube is separated from the river whenever it is accessible is, while the other end contact is in a socket the lamp socket, which can be live.

The invention is based on the object of this requirement in easier and safer way to meet.

According to the invention, this object is achieved in a socket for one end of a double ended electric (ilbulb or fluorescent tube characterized by a lower part and a removable cover cap with at least one plug-in contact part,

Q300U / 0781

which engages in a socket in the lower part and in his Engagement closes a two-pole switch, which is an electrical Establishes connection between a main terminal and a contact which is arranged so that it is inserted into the socket at Lamp rests against a contact at the end.

In the case of a socket for receiving a double-ended electric light bulb or fluorescent tube, the above-mentioned problem is solved characterized by a lower part and a removable end cap for at least one end of the lamp or ear, Each end cap has at least one plug contact part, which engages in a socket in the lower part of the lamp socket and when engaged, a two-pole switch closes, which establishes an electrical connection for a contact of the lamp socket, which is arranged so that it is in the socket inserted lamp rests against a contact at the end.

When one or the other end cap is removed from the base is so that one end of the lamp is exposed, then the two-pole switch is opened in this way, where the contact

the
is interrupted for the / tteiden ends of the lamp receiving base and both lamp ends are de-energized. This solves the given problem.

A socket according to the invention makes it possible to have a free space of at least 8 mm between any live Part, d, .h. a part connected to the main lead, and any other electrically conductive part.

The two end caps can either be used as separate components be designed or they can be with a light diffuser <jr or a shield extending along the lamp socket or holder can be made in one piece.

The arrangement of plug contacts on the closure caps is one A matter of choice, for example, four such plug-in contacts can be used be provided as two pairs - one on each side of the end cap - are grounded to each other, with the connector on opposite sides are connected to each other and each plug has a contact that is connected to a contact in the lamp holder socket comes to the intervention. Not another, sometimes preferable arrangement; sees two plugs - one on each side of the End cap - before, each plug has a contact which, in use, lies over two contacts in the base, so 'let a connection is established between the socket contacts.

The plug contacts are preferably with a lock or latching device provided, which are resilient in a zu.c-assigned device or surface in the base engages so that the end caps on the socket during normal use in their In a position that they can be removed if the lamp needs to be replaced.

The contact in the socket against which the end contacts of the lamp close, is preferably formed as a small coiled piping ai sg <; -, which helps keep the lamp pliable in its socket while maintaining a perfect contact connection in their Able to hold.

A preferred embodiment of the invention is illustrated in FIG Drawings described. Show it:

Fig. ^R j is a perspective view of a Kndabschnitts the socket, as seen from below and with removed floor plate;

FIG. U shows a partially sectioned end view of FIG. 1; Fig. 7 shows a compression coil of the socket according to the invention.

The socket or holder has a lower part 2 with a standing base k at each end for receiving an end part 8 of a tube lamp 10. This lamp extends over the entire length of the socket, its end contacts being in contact with a helical spring 12 which is held in the base Ί.

An end cap l4 serves to cover each base k of the socket and to surround and protect the end parts B of the lamp 10.

The tube lamp 10 inserted into the socket rests on a curved one Support l6 and is resiliently held between the two springs 12 acting from each end.

Either two separate end caps can be provided or the end caps can be made in one piece with a light diffuser or a shield 18, which extends over the lungs of the socket and surrounds the lamp 10, is formed be, as shown in Fig. 1 on the right.

Each end cap has two downwardly directed plug contacts 20 - one on each side - which engage in plug-in sockets 22 (see FIG. K) on each side of the lower lamp part 2.

Each plug contact 20 is provided with a conductor 'Ik , which extends over the width of the inside of the contact 20 and,

• 3Ö0U / 0781

when the Kentakt is received in its socket, two contacts 26 (see FIG. 3) are bridged with one another. These contacts 26 are attached to the lower part 2, are part of a two-pole switch arrangement and, when they are connected by the conductors 2k to the plug contacts 20, complete the circuit to the contact springs 12 for the tube lamp.

Thus, when both end caps Ik are attached to the socket in the correct position, power is supplied to the lamp.

It is clear that the lamp cannot be removed or that its leading ends cannot be touched while the end caps Ik are in place. However, if an end cap Ik is removed, both end caps are cut off on the current side, and the lamp can be safely removed.

The end caps are barbed on their front or rear wall 28 provided, which has a slot 3 ^ in the end wall come to rest against the lamp socket with one shoulder; further barbs 32 are also provided on the outside of the plug contacts 20, which are located under a shoulder below the inlet reach into the jacks 22.

In this way, the end caps are held securely in their position on the lamp socket. Should the end caps removed both side faces /.usaramen are pressed, so that the barbs 32 are off their respective shoulders come free and the plug contact part from the plug bevels 22 can be pulled out.

The wire for each end-side base of the lamp socket 4 can be easily connected in the usual ise W _e, by the stripped ends into holes to the holes 3 '* in Kig. 5, to be pressed in. The wire ends are then gripped and held by a flexible contact member, ie the connection is made with it.

As it is desirable to place between any metal part and any stronif it is the part to provide effective insulation
To have a minimum distance of 8 mm, the distance between the two fixed contacts 2b in the lamp base Ü is normally chosen to be greater than 8 mm.

The wiring of the lamp assembly according to the invention, with a two-pole switch arrangement 36 provided at each of its ends
is shown in FIG.

A kin / off switch and / or can also be installed in the lamp socket
a connection for an electric shaver may be included.
