DE961730C - Socket for ring-shaped fluorescent lamps with four connection pins - Google Patents

Description

The invention relates to a socket for ring-shaped Fluorescent lamps with all four pins ending in the socket.

While such sockets are known, one type is a one-piece housing has, the insertion of the contact sockets and those line connection difficult. Also is that Insufficient insulation between the individual contact sockets. The nipple is separated from the socket housed in a special housing with which it is connected to the socket.

In another embodiment, the socket housing is in the direction of the supply cable divided longitudinally, but with the contact sleeves in recesses running perpendicular to the plane of division of the housing halves are inserted. This version is very expensive to manufacture, in particular in that the housing parts are very bulky and the contact sockets are also very large. Two fastening screws are therefore also necessary to hold these known housings together. In contrast, there is no nipple nut, which makes the socket incomplete. It would take on even greater proportions if it were there.

Another known device has a split in the longitudinal direction of the contact sockets Housing, which is also held together by two fastening screws.

A version is therefore proposed whose structure is simple and expedient and in addition, the modern requirements

fits is. The socket, which is divided in the longitudinal direction of the line, consists of two almost equal parts. One The difficult task is to find the four used in recesses of longitudinally divided housing halves Sufficiently isolate contact sockets from one another.

According to the invention, the two are mutually exclusive corresponding shell-shaped housing halves in their upper part two by one ίο Separation bar separate recesses for inserting two in the direction of the dividing plane arranged running contact sockets, while in its lower part the two housing halves in a complementary recess provided with an adjusting screw for fastening the Take up the connecting tube serving nipple nut and the contact sockets of both halves be separated by an insulating plate in the bucket recess between the housing halves ao is clamped, the housing halves by a fastening means penetrating the separating webs be held together. The insulating plate has a U-shaped shape and is so in the Socket used that its U-shank upwards are directed. The one connecting the two U-legs Part engages in corresponding recesses in the separating webs of the two housing halves a.

The new version is shown in the drawing in four figures.

Fig. Ι shows a perspective view of the socket,

Fig. 2 shows a section through a pair of contact sockets perpendicular to the parting plane of the housing; Fig. 3 shows a housing half with an interior view in perspective, and

Fig. 4 shows the insulating washer separating the contact sockets on its own.

The four contact sleeves are in the housing 1 (Fig. 1) 2, 3, 4 and 5 combined to receive the four tube pins of the ring-shaped lamp. That Housing made entirely of insulating material consists of two parts 6 and 7 (Fig. 1 and 2). The contact sockets are located in recesses of the two corresponding and complementary housing halves 6 and 7 and are paired by the. Isolation plate 8 (Fig. 2) from each other separated. The insulating plate 8 (Fig. 4) is U-shaped and is between the two Housing halves in recesses 14 of the housing and in recesses 15 of the webs 9, which each separate two contact sockets in a plane perpendicular to the parting plane of the housing, held. The insulating plate points upwards with its U-legs, while the connecting Part of the U-legs in the recesses 15 of the Separation webs 9 engages.

In the lower part of the two housing halves there is a recess 10, into which a nipple is used with adjusting screw 13 for the connection of a pipeline. Both halves of the housing are, by a screw 12, which of the Kantakt sockets 2, 3, 4 and 5 and also completely isolated from the threaded nipple 11, held together. Here, the fastening screw penetrates the separating webs 9 of both housing halves 6 and 7 in holes 16.

The construction of the socket is very simple and enables the quick and easy connection of the Supply lines. However, the perfect insulation between the individual is particularly important Contact sockets with each other and between the contact sockets and the connecting screw on the one hand and the connecting screw and the nipple nut on the other.

Claims (3)

PATENT CLAIMS: ι. Socket for ring-shaped fluorescent lamps with four connecting pins, in which the housing accommodating the loose contact sockets in the longitudinal direction of the introduced lines is divided, characterized by two corresponding, shell-shaped housing halves (6, 7), which in their upper part each two recesses separated from one another by a separating web (9) for the insertion of have two contact sockets (2, 4 or 3, 5) extending in the direction of the parting plane, in their lower part in a complementary recess (10) in both halves with a set screw (13) provided nipple nut (11) in take up and which with the interposition of the contact sockets of both halves of each other separating insulating plate (8) are pressed together by a fastening means (12), which penetrates the separating webs of both housing halves. 2. Socket according to claim 1, characterized in that that the inserted insulating plate (8) in a recess (14) in both housing halves is used. 3. Socket according to claim 2, characterized by an insulating plate (8) U-shaped, which is inserted into the socket so that its U-legs are directed upwards while their part connecting the two U-legs in ■ corresponding recesses (15) of the separating webs of the two housing halves engages.
