Title of the invention

Coupling device, in particular socket for luminaires

Field of application of the invention

The invention relates to a coupling device, in particular Einbaufassung for lights, which consists of a one-piece insulating body. The fit serves for contacting and holding the light source in luminaires, fluorescent lamps being particularly suitable as the light source.

Characteristic of the known technical solutions

For contacting and mounting of fluorescent lamps in lights several coupling devices are known, which together have the disadvantages that the! Version consists of several Isolierstoffteilen and that the line connections via screw or spring terminals are made * Moreover, they are automatically assembled only with great effort.

Fits, as proposed by WP 57 156, WP 142 481, WP 127 and WP 136 082, ensure the contact between fitting and socket pins of the fluorescent lamps by one-sided contact of the socket pins on spring contacts, wherein the locking reaches the contact position by a rotary body with Hastsegmenten becomes. The line connections are ensured by screw or spring terminals. A socket according to DE-OS 2 921 590 has contact arms bent to make contact with two legs, so-called jaw contacts, into which the base pins of the fluorescent lamp are latched. This solution has the additional disadvantage that it is very material-intensive. A Polish version, which is available as a sample and also consists of several insulating parts, has a two-sided contacting possibility via notches.

Object of the invention

The invention aims to provide a coupling device, in particular a one-piece Einbaufassung for lights that ensures safe positioning and contacting vo.n fluorescent lamps in lights and is economically and technologically inexpensive to manufacture and further processed,

Explanation of the essence of the invention

The invention has for its object to develop a one-piece Einbaufassung for lights that holds the fluorescent lamp safe, allows the insertion and removal of the lamp from the lamp with simple or no tools and compensates for their length tolerances, a stable and stable over a long period of use Contacting both between, connecting line and contact

clamp the fit and between the contact terminals and the base pins of the lamp guaranteed · Furthermore, the invention has to fulfill the task that the Einbaufassung automatically produced and automatically processed in the assembly process of the luminaire · According to the invention, this object is achieved in that in one one-piece cylindrical insulating body, whose diameter is greater than that of the fluorescent lamp, parallel to the diameter and at a distance of the base pins of a fluorescent lamp two sleeves are inserted, the metallic contact terminals record arresting. The sleeves have to lock the contact terminals at least one, preferably two outstanding retaining lugs, which engage in corresponding recesses of the contact terminals *

The contact terminal is U-shaped resilient and has two laterally projecting contact surfaces whose outer edges are widened in a Y-shape · In the legs of the U-shaped contact terminal recesses are mounted, which serve to lock in the sleeve. At the contact terminal, the connection line in variable length is preferably permanently attached. The Isolierstoffkörper has two through holes for selectively receiving the length-compensating cylinder springs and fasteners. At the periphery of the insulating material are outstanding segments that serve the sliding position fixing the Einbaufassung in the luminaire housing and / or their attachment. Likewise, a collar projecting in the direction of the fluorescent lamp, whose inside diameter approximately corresponds to the diameter of the fluorescent lamp cap, can be attached to the circumference of the insulating material body.

embodiment

The invention will be explained below with reference to an exemplary embodiment.

In the drawing show

Figure 1: the view of the mounting frame figure 2: a section through the socket

An insulating body produced by injection molding, which preferably consists of a thermoplastic, contains the holes 2 and 5 and the sleeves 3 · The contact terminal 7 is made separately in the cutting-bending process of resilient contact material and the lead 8, for example, soldered, pressed or wound · The Einbaufassung is manually or automatically mounted by the contact terminal 7 is pushed into the sleeve 3 of the insulating material until the holding mass engage in the corresponding recesses of the contact terminal 7 and lock them ·

The installation of the socket in the lamp is done by inserting a cylinder spring and optionally a fastener in the bore 5, the insertion of the socket into a corresponding receptacle of the lamp with the segments 6 slidably move in buten recording and fastening is done for example by Yerschrauben. It is also possible to use the segments as a locking device of the Einbaufassung in the recording su. To ensure the length compensation when inserting or removing the fluorescent lamps or to their length tolerance compensation, the sliding-resilient mounting of only one Einbaufassung is required, while the second Einbaufassung can be rigidly attached «

When inserting a fluorescent lamp, the socket pins are inserted into the holes 2, wherein the socket pins are contacted between the contact surfaces of the contact terminal 7 at two Kontaktspxankten. Taking advantage of the sliding-resilient mounting the Einbaufassung the base pins of the opposite end of the fluorescent lamp are inserted into the rigid or spring-mounted mounting recess. The spring force of the cylinder springs is dimensioned so that the fluorescent lamp is securely held between the mounting posts.
