Description

REGULATION OF DISTRIBUTION FOR THE TECHNIQUE OF TELECOMMUNICATIONS AND DATA Description: The invention relates to a distribution strip for the telecommunications and data technology, in particular for the main distributor of telephone and data lines according to the preamble of claim 1. Such distribution devices, in particular for the main distributor of telephone installations, they serve as a point of intersection for user zones and telephone facilities intermediation areas. From DE 195 37 529.7 a distribution strip for the telecommunications and data technology is known, in particular for the main distributor of telephone and data lines, which has cut and hold contact elements for the connection both of the user cables as well as the intermediation cables, and which is assembled in a modular manner and contains contact springs formed in one piece inside. The one-piece contact springs arranged inside the distribution strip are formed by connection contacts according to the cutting and clamping technique on the front and rear side of the terminal strip and by a telecommunications contact in the central area. The telecommunications contact consists of two contact surfaces, which can be formed as double contacts. A tap contact is formed in the front area of the contact spring. The manufacture of these one-piece contact springs is complicated. The object of the invention is to develop a distribution strip containing a contact element which is structured in a simple manner and in which the wire guide is improved and a secure placement of the cable webs is ensured. The solution to this task results from the features of claim 1. The two-part contact spring made according to the invention from a base part and a contact spring part ensures uncomplicated manufacture, with space saving and automatable of the contact elements of the distribution strip. By means of the two-part embodiment of the contact spring, different materials can be combined, which ensure an optimization of the characteristics of the contacts in terms of the spring paths, contact forces and protection functions to be satisfied. The molded bodies, formed adjacent to the housing parts on the one hand in the region of the cutting and clamping contacts, ensure that the positioning tool can only be applied in one direction to the cutting and clamping contacts. This ensures that the wire to be connected is always cut on the correct side. The channels for guiding wires provided by one of the surfaces of the modules facilitate the assignment and guidance of ordering wires to the contacts. Other advantageous structures of the invention result from the dependent claims. The invention is explained in more detail below with reference to an exemplary embodiment, represented in the drawings, of a distribution strip. They show: figure 1 the side elevation view of a contact spring, figure 2 the plan view from above on the contact spring according to figure figure 3 the side elevation view of the base part of the contact spring according to FIGS. 1, 2, FIG. 4 shows the plan view from above on the base part of the contact spring according to FIG. 3, FIG. 5 shows the side elevation view on the contact spring part of the contact spring according to FIG. Figures I, 2, Figure 6 the plan view from above on the contact spring part according to Figure 5, Figure 7 the perspective view from above on a completely assembled module of a distribution strip, Figure 8 the perspective view from above on the module according to the open figure 7 of a distribution strip, figure 9 the perspective view from above on the underside of the module according to figure 7 and the figure 10 shows an enlarged representation of a partial area of the grooves for the cutting and clamping connection contacts.

For the constitution of a main distributor in telecommunication and data networks, distribution strips composed of modules 17 according to FIGS. 7 to 10 are arranged on vertical blocks in assembly tables, not shown, on top of each other. Each distribution strip forms a functional module, for example in connection contact position or in separation contact position. The distribution strips consist of equal modules 17 and differ only in their relative position or in the arrangement of contact springs 1 according to figures 1 to 6 as well as in the connection with or without a protective plug against overvoltages or the like. Each distribution strip consists of two modules 17 of the same structure with cameras 15 and grooves 16, which arranged one above the other do form the distribution strip, a contact spring 1 (FIG. 9) being placed in the chambers 15 respectively. In the slots 16, the front and rear cutting and clamping contacts 7, 8 of the contact springs 1 are accessible (FIGS. 1 to 6). In the contact area 18 of the cutting and clamping contacts 7, 8, a shaped body 9 is attached on one side to the housing parts of the modules 17, which ensures that a positioning tool can only be applied in one direction on the cutting and holding contact element 7, 8 (FIG. 10). This ensures that the wire to be connected is always cut on the correct side. The contact spring 1 is made in two parts corresponding to the representation in figures 1 to 6 and is formed by a base part 3 and a contact spring part 2. Parts 2, 3 can be manufactured from materials different, to achieve optimal values for the spring paths and contact forces. The base part 3 according to FIGS. 3, 4 forms the base for the contact spring 1. The base part 3 comprises at each end of a cutting and holding contact 7, 8. In the central area, fixing points are provided 4 for the longitudinal direction. A bore 5 serves for fixing in place the contact spring part 2 to be placed on top, and an opening 6 serves to pass the inserted spring part 2 therethrough. A tap contact 19 serves to establish contact with test plugs. The contact spring part 2 according to FIGS. 5, 6 consists of four zones. The first zone I with a guide button 20 and a welding protrusion 21 serves for fixing the contact spring part 2 to the base part 1, for example by welding. The second zone II is the bending zone, to ensure the spring travel in zone III. The zone III with the two contact surfaces 23, 22 for protection against overvoltages and the telecommunications contact is reinforced by a reinforcing joint 24, to obtain approximately the same spring travel at both contact points 22, 23.

The zone IV serves for the support of the prestressed spring part 2. The contact surfaces 22 of the contact springs 1 of the modules 17 assembled as upper part and as a lower part abut each other in the assembled distribution strip and form together the actual telecommunications contact of the distribution strip. The zones I to IV of the contact spring part 2 can be varied in their mutual length ratios to optimize the spring forces required. Figures 7 and 8 show channels 10 for guiding wires, which are formed in one piece from a housing part of one of the modules 17 of the distribution strip. These channels 10 have bridges 11 on which an electrically conductive screening plate 12 can be fixed to cover the upper side of the distribution strip. The screening plate 12 has an elastically-shaped tongue 13 (FIG. 9) which is bent in such a way that it can be guided in the location 14 (FIGS. 8, 9) through the housing part of the respective module 17 and produces, when assembling the module 17 a ground connection to the frame not shown.
