DE2362404A1 - Socket for fluorescent lamp compensating capacitor - has slider allowing capacitor to be switched from series to parallel compensation connection - Google Patents

Abstract

The socket for a fluorescent lamp compensating capacitor has two contact holes at one end for the compensating capacitor pins, and three contact holes at the other end to connect with the rest of the lamp circuitry. The socket has a rectangular hole through its side faces. A slider fits into this hole and can be moved between two positions, one connecting the capacitor for series compensation, and the other connecting it for parallel compensation. The slider has three contacts on one side surface, and three contact holes on its other side face. A notch acts as a positioning ratchet.

"Terminal for connecting a capacitor for series or Parallel compensation of fluorescent lamp luminaires "

• There are terminals for connecting a capacitor for series or parallel compensation of fluorescent lamp luminaires for example by the French patent 1 4-80 9 ^ 5 known. In the case of the 3-poügen described here Terminal is a short-circuit bridge that can be clamped from the outside provided, which must be removed when connecting a capacitor for series compensation. For the capacitor are In addition, special measures are required because ge after Type of circuit the capacitor must have a different distance between its connecting lugs,

One terminal has already become known, its insertion openings for the capacitor to the distance between the connection lugs However, different insertion openings are provided for series or parallel compensation.

The invention aims to provide a terminal for connecting a capacitor for series or parallel compensation of To create fluorescent lamp lights that are particularly simple and reliable. Is according to the invention a contact carrier, which can be changed in its position and has three contact elements, is provided in the terminal body which in the operating position are each two behind capacitor connection openings of the clamp body and with two of three mains or lamp circuit leads are connected, with an im Terminal body arranged, for bridging two of the three supply lines serving contact in the operating positions of the contact carrier is kept open or closed. The contact carrier consists of a slide on which the Contact elements as sockets, viewed in the slide direction, are arranged at the same height and at the same distance from one another and the sockets on the side facing the power supply or lamp circuit supply lines are transverse to the longitudinal axis of the slide Have angled contact tongues, two of which are adjacent are angled opposite to the third. -In the terminal body are on the facing the contact tongues Side with these depending on the contact carrier position in contact connection spring clips provided for the leads, two of which are on the same Height with the contact tongues angled in the same direction and the third at the height of the oppositely angled Contact tongue are arranged. The contact tongues, angled in the same direction, are connected to the associated contact spring !!. in one end position of the contact carrier and the diagonally arranged carrier in the other end position of the contact in contact with the corresponding springs.

Operating positions of the terminal.

The terminal shown in the drawing consists of one Terminal body 1 and a contact carrier 2 designed as a slide. On one side of the terminal body there are two Connection openings $ and 4 for connection tongues 5 of a capacitor 6. On the other side of the clamp body are there connection openings 7 * 8 and 9 frö? Network or ■ Lamp circuit leads 7a »8a, 9a. In the clamp body are located behind the connection openings 7, 8, 9 terminal springs 7b, 8b, 9b (Pig. 3 and · Ψ). The terminal spring 96 is not visible because it is located under the clamping spring 8b. In the terminal body is between the terminal springs 7b, 8b a contact bridge 10 is provided, the meaning of which will be explained later. The contact carrier 2 is displaceable in the terminal body and has three Sockets 17, 18, 19 on, the same distance from each other have and seen in the longitudinal direction of the slide on the same Height. The sockets have angled contact tongues 17a, 18a, 19a, which are located on the side of the contact carrier facing the terminal springs 7b, 8b, 9b

are located. The contact tongues 17a ₅ 18a are angled towards the same side and are level with the terminal springs 7b, 8b, while the contact tongue 19a is bent towards the opposite side and is level with the terminal spring 9b. Distinctive elements are provided for guiding the contact carrier 2 in the correct position in the terminal body 1. On one narrow side, the contact carrier 2 has a groove 11 over its length into which a web 12 arranged in the terminal body engages over the width of the terminal body. A recess 13 is also provided in the contact carrier between the contact tongues 17a and 18a, at the level of which the contact bridge is located in the terminal body 1.

The mode of operation of the clamp is clear from Mg. 5 and 6. In the position of the contact carrier 2 according to FIG the capacitor 6 is inserted into the connection openings 3 and 4-, so that its connecting tongues 5 in the sockets 17 and 18 intervene. Stand over the contact tongues 17a and 18a these sockets with the power line 7a or with the line 8a in connection. The line 8a is connected to a choke 14 which is in the circuit of a fluorescent lamp 15. The other end of the throttle is connected to the electrode 15a the fluorescent lamp in connection, while the other electrode 15b to the lead 9a which also leads to the scrap connected. The electrodes 15a and 15b are known in FIG Connected to a starter 16. By engaging in the sockets 17 and 18 connecting tongues 5 cLes Capacitor 6, the contact carrier 2 is blocked in its position. In the groove 13 (Fig. 2b and Fig. 3) of the contact carrier, the contact bridge 10 is spring-loaded so that between

the terminal springs 7b and 8b no contact connection consists. The supply line 9a has in the in Fig. -I? shown Position of the contact carrier only connection to the lamp electrode 15b inside the clamp. The capacitor 6 is in this switch position directly in the lamp circuit, -so that these. The switch position corresponds to the series compensation. - "" ■ - ..

If the capacitor 6 is plugged into the terminal when the contact carrier 2 is in the position shown in FIG. 6, it is connected to the network directly via the lines 7a and 9a. The groove 13 of the contact carrier is located outside the area of the contact bridge 10, so that it is pressed against the terminal springs 7; t> and 8b by the contact carrier and connects the springs. The contact bridge thus provides thus an electrical connection from the power supply line 7a to the preceding throttle 14 for _managerial: tung 8a forth. In this switching position, the capacitor 6 is parallel to the lamp circuit, so it is in a parallel compensation position. ■ ·

The clamp according to the invention is particularly advantageous because it can be made relatively easily that Contact carrier to be inserted unmistakably in the terminal body λ and only two insertion openings for the capacitor. ties are. Mixing up circuits is as good as impossible because of the protruding from the terminal body Ends of the contact carrier made clear switching parameters can be. The contact carrier only needs to be brought into the desired switching position. The capacitor needs then only to be plugged into the connection openings.
