Description

The invention relates to one provided with screw, sleeve and plug pin contacts Power connection device.

The previously known devices of this type consisted of many parts and were therefore expensive to manufacture and cumbersome to assemble and use.

The device according to the invention consists only of two main parts, of which ίο which has a contact sleeve arranged parallel to the longitudinal axis, with an external thread is provided and the shape represents a cylinder, while the other part on the one hand has the pair of pins that fit into the contact sleeves, on the other hand the for. Screw in the cylindrical part matching Threaded hole and also contains the connection for the line cable.

This creates a connecting device ground from a previously unattainable compact and material-saving design, the following Application options offer:

a) Is the cylindrical part by means of its contact sleeves on the connector pins of the other Part "plugged on, so you can screw the device into a lamp thread, with the thread of a pin and the external thread of the cylindrical part is held in the lamp socket, so that in addition to the

attached to the device, a consumer device feeding cable at the same time a lamp can be connected in the threaded hole of the connector body. b) If the cylindrical part is screwed into the threaded hole of the plug body, the device with the pins can be plugged into any normal socket, whereby, in addition to the appliance powered by the cable connection, another plug can be inserted into the sleeve contacts of the cylindrical part so that the device also serves as an adapter. c) The plug on its own can be inserted into any normal socket, and at the same time a lamp can be screwed into its threaded hole. The drawing shows an embodiment of the invention. Fig. Ι shows a longitudinal section through the device with a screwed-in cylindrical part and exposed connector pins. Fig. 2 is a diagram of the device of Fig. 1 viewed from the side. Fig. 3 shows a diagram of the cylindrical part. Fig. 4 shows a cross section through the device along the line x-x in Fig. 2, and Fig. 5 shows the device when used for connection to lamp sockets with a screw cylinder part attached. In Fig. Ι α is the actual body of the power connection device, which is provided with two contact pins a1 and ß2. b is a cylindrical screw contact piece with an external thread which is screwed into the body α provided with the corresponding internal thread. The contact pin ß1 has a semicircular cross-section and is provided with a thread on the one outer surface, as can be seen from Figs. The screw contact piece b has two contact sleeves b1 and b2, of which, as Fig. 3 shows, the sleeve b1 is pressed segment-shaped into a corresponding recess in the outer surface of the screw contact piece b, while the sleeve b2 is an ordinary sleeve with a full circular cross-section and into the interior of part b protrudes. The contact pin a1 is conductively connected to the contact sleeve b1, while the contact pin a2 is conductively connected to the center piece d in part α by means of a screw c. The middle piece d is connected to the head e of a screw / conductively, which is screwed into the contact piece b. In the manner shown in Fig. 2 and 4, a cable g can be connected to the connector pins. If the device is to be used for connection to a lamp socket, part b must be unscrewed, as a result of which the internal thread of part α is free for screwing in a lamp or the like. Then, as shown in Fig. 5, part b is placed on the pins a1 and a2, so that the pin ä1 engages in the segment-shaped sleeve bx and supplements the thread missing here, while the pin a2 fits into the cylindrical sleeve b'2 pushes in. If the device is used as shown in Fig. 5, in that the connection is made through the threaded contact piece b to a lamp socket, the advantage here is that the plug is firmly seated in the lamp thread and cannot be removed by mere pull, since the contact pin α with its thread, which forms the complement to the missing thread of part b in bl, engages in the thread of the lamp socket. The device can therefore only be screwed out of the lamp thread at the same time as part b, but not pulled out. Ρλτεν τ-An s ι κ f <.: 111 :: :: 1.
