Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The invention relates to an arrangement for fixing electrical conductors in a distributor of a telecommunications device, in particular a telephone device. The arrangement comprises parallel lightning arresters as transverse members to earth and a fuse as a longitudinal member, the fuse being brought into contact with the contact members at both poles, one of the contact members being , in which the contact member adjacent to the associated surge arrester is connected to one pole of the surge arrester, and the other pole of the surge arrester is connected to a multiple earth line.

Prior Art An assembly of the type described above is disclosed in West German Patent No. 321201.
It is known from specification No. 3.

The fuse and arrester are held at the poles by contact pieces, which are fixed to the support member of the arrangement.

The contact piece ends in a contact surface, which is arranged along the longitudinal edge of the arrangement and is brought into contact with the plug-in contact of the contact spring of the membrane module. The support element is designed as an injection molded part, into which the contact piece is inserted. The contact pieces, like the fuses, extend approximately perpendicular to the direction of the rows. A small tubular fuse is held at its ends between vertically curved contact portions of the contact piece, which contact portions extend from the contact surface to either side of the support member of the arrangement. The contact portion is bent away from the contact piece at the longitudinally oriented folded edge of the fuse.

It can be seen from the drawing that one pole of the fuse is directly adjacent to the associated muffler. This pole is connected together with one pole of the δ avoidr by means of a spring leg of the directly associated contact piece. The other pole of the lightning arrester is in contact with the vertically bent tongue of the IJ-shaped multi-ground line, and the multi-ground line is connected to the ground spring of the membrane module and the receiver of the sump of the assembly. is forced to come into contact with

Furthermore, it is known from German Patent No. 2,508,845 to use an arrangement without fuses. In this arrangement, the lightning arrester, which is oriented perpendicular to the support element, rests with its earthed pole on the spring finger of a U-shaped earthing plate. The poles of the arrester pool rest on flat melting pieces, which abut the contact zones of the pocket pieces. The contact piece has a U-shaped vertical bend that reaches its highest point immediately adjacent to the end of the spring finger. When the molten piece melts, the spring fingers are lowered by 4 degrees such that the contact piece is directly grounded.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fuse and lightning arrester arrangement with a short-circuiting method of the type described above with little extra cost.

Means for Solving the Problems The present invention provides a means for solving the problem in which, in an arrangement of the type described at the outset, the multiple earth conductors are provided with molten pieces by means of spring fingers. The lightning arrester is in contact with the lightning arrester, and the spring finger or the arrester protrudes close to the associated contact member, and the distance between the contact member and the spring finger in the spring rebound direction is greater than the thickness of the melted piece. It's a small thing.

Advantages of the Invention Since the spring finger projects close to the contact element for the fuse, space can be saved, for example by eliminating vertically bent bends. When the melting piece melts, the spring finger rests directly on the contact element for the fuse, so that the corresponding conductor path is directly grounded.

lol! Advantageous embodiments of the non-inventive aspect A are described in claims 2 to 7.

The embodiment according to claim 2 makes it possible to realize a printed conductor plate with conductor tracks on both sides in a cost-effective manner. The vertical arrangement of the δ arresters allows the arresters to be arranged offset from each other with small distribution spacing to save space. The contact zone of the surge arrester reservoir is constructed as a simple extension of the conductor track. The escaper together with the melting piece is held tightly between the conductor plate and the spring finger.

The embodiment according to claim 6 allows a double contact between the contact element and the spring finger with a correspondingly higher contact reliability.

Claims! The embodiment according to item g4 allows multiple earth lines to be fastened to the arrangement in a simple manner without additional fastening elements. The contact safety of the arrangement is also increased because the spring fingers cover not only the lightning arrester but also the contact members of the fuse reservoir, which are exposed to the risk of overvoltage.

The embodiment according to claim 5 combines the advantages of injection molded parts with the advantages of printed conductor plates. With the embodiments according to claims 6 and 7, the arrangement can be optimally configured for better production, implementation and handling, with the use of contact elements and other modifications. A variety of fuses can be used for the arrangement without any.

According to the embodiment, FIG. g1, FIG. 2 and FIG. 6, the arrangement 1 has the following:
It includes a conductor plate 2 pasted on both sides, a casing member 3, a contact member 4, a fuse 5, a lightning arrester 6, a melting piece T, and a multiple earth wire t48. Along its longitudinal edge, the conductor plate 2 is provided with a contact surface 9 on the screen for a contact spring 10 of a membrane module in a distributor of a telephone exchange. The two contact springs 10 located one above the other are electrically connected to each other A via a conductor track 11 of the conductor plate 2, a contact member 4 and a fuse 5. One conductor track 110 is arranged on the side of the conductor plate 2 facing the fuse 5 and the lightning arrester 6 and, via a corresponding contact spring 10,
It is connected to the outer core of the subscriber conductor.

This conductor track extends below the surge arrester 6, where it forms an enlarged contact zone of the reservoir of melted flakes γ. The melting piece T is held between the lightning arrester 6 and the contact zone.

This conductor track 11 is guided on a soldering eye which is made into a through-contact, the soldering eye directly adjoining the contact point for the lightning arrester 6. In this soldering, one contact member 4Q for a fuse is soldered inside the eye.

A further contact element 4 is soldered to the soldering eye adjacent to the contact surface 9, this contact element being connected to the conductor grating 2.
connected to a conductor track located on another side of the

The flat contact element 4 is of fork-shaped construction and holds the fuse 5 in the pole piece between the spring legs 12. The contact member is upright and is soldered in the hole through which the conductor plate 20 is brought into contact with the protrusion 21. Surge arresters 6 arranged vertically on the conductor plate 2 and offset from each other are held between the spring fingers 14 and the melting piece 7 of the multiple earthing line 8 of the control. The spring fingers 14 extend onto the free end faces of the contact elements 4 which are adjacent and offset relative to each other. The distance between the spring finger 14 and the contact member 4 is less than the thickness of the melting piece γ. When the J melting piece melts, the spring finger 14 contacts the contact member 4, so that the conductor line is directly grounded. The spring finger 14 has a slit at its free end on the contact member 4, which provides a double contact on the contact member.

The multiple earth lines 8 i, i are constructed as U-shaped bent sheet members, contacting the plate 2 with four legs and surrounding the arrangement 1.

A housing part 3 made by injection molding is mounted on the conductor plate 2 and is connected thereto by hot pressing with projecting pins 15. The pin passes through a hole in the conductor plate 2. The housing part 3 constitutes a receiving part for the lightning arrester 6 and the fuse 5 and is provided with a circulating protective lip 16. The protective rim mechanically stabilizes the arrangement. Furthermore, gripping elements (not shown) are attached to the casing part 3 to facilitate handling of the arrangement.

4 and 5, the device 1 has a U-curved contact member 1 instead of a flat contact member 4 (FIG. 1).
8, the contact member is soldered into the eye 2 of the conductor plate 2 with its legs. The displaceable, free spring legs face each other in pairs and each have a small, tubular, short fuse 19 clamped on their end side. The free legs of the contact element 18 extend up to the support plate and spread out from each other, thereby pressing the fuse 19 against the space of the housing element 3. The distance between the two legs of the contact member 18 is equal to the fuse 19
It is adapted to the length of the The contact member 18 rests on the stop shoulder 17 of the housing member 3 with its end opposite to the conductor plate side and on the side facing away from the fuse. This reduces the spring action distance and increases the tightening force. The contact members 18, which are offset from each other 2 in accordance with the position of the lightning arrester 6, have tongues 13 protruding in the direction opposite to the conductor plate 2 at the extensions of the soldered legs. The piece has a similar function to the spring finger 14 as the flat contact element according to FIG.

According to FIGS. 6 and 7, the free spring leg of the contact element 18 is curved concavely in the longitudinal direction towards the fuse 19, so that it is secured in a position lateral to the fuse vi. There is.

According to FIG. 8, the fuse 19 is first pressed with one end obliquely against the contact member 18. The contact member has a very large margin so that the contact member can be displaced enough to cause the end face of the fuse 190 to slide against the base portion of the other contact member 18. The contact element abuts with its free leg end an opening 20 which prevents the preloaded free spring leg from returning too strongly.
