Description
This is a Continuation of U.S. Ser. No. 10/508,093, filed 12 Apr. 2005, which is a National Stage of PCT/EP03/01717, filed 20 Feb. 2003, which claims priority to 102 11 826.4, filed 16 Mar. 2002, in Germany, and which applications are incorporated herein by reference and a claim of priority to all is made.
TECHNICAL FIELD The invention relates to a plug for terminal blocks of telecommunications and data systems equipment and a method for its production.
BACKGROUND OF THE INVENTION Terminal blocks for telecommunications and data systems equipment typically comprise a first row of contact elements for connecting incoming wires and a second row of contact elements for connecting outgoing wires. Arranged between the assigned contact elements of the first and second rows are tapping contacts, into which measuring, test and protective plugs can be inserted. The tapping contacts are designed as connecting or disconnecting contacts. The known test and protective plugs are symmetrically constructed, with the housing of the plug covering the contact elements of the first and second rows of contact elements, so that they are not accessible for activation purposes. If the fitted connecting cord of the measuring or test plug happens to be a temporary patch connection and if the temporary patch connection is to be replaced by permanent jumpering, the subscriber connection must first be disconnected by removing the plug before the permanent jumpering can take place.
SUMMARY The invention is therefore based on the technical problem of providing a plug for terminal blocks in telecommunications and data systems equipment which is simple to produce and allows interruption-free insertion in a tapping contact of a terminal block, and also of providing an associated production method.
BRIEF DESCRIPTION OF THE DRAWINGS The invention is explained in more detail below on the basis of a preferred exemplary embodiment. In the figures:
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 and 2, a plan view and a bottom view of a lower part 1 with a galvanic link 2 are perspectively represented. The lower part 1 is in this case made up as one piece by a basic body 3 and a core part 4 to be metallized. The core part 4 comprises metallized structures, which are formed as contact elements 5, interconnects 6 and terminal elements 7 and are galvanically reinforced. For this purpose, for example, the lower part 1 is produced in a two-shot injection-molding process, with a metallizable, pretreated plastic being injected by means of the first shot and the basic body 3 being molded by means of the second shot, with the later contact elements 5, interconnects 6 and terminal elements 7 remaining free. On these exposed surfaces, a basic metallization is built up in a chemical process. Subsequently, the lower part 1 is attached by means of the electrically conducting galvanic link 2 to a supporting frame, which is connected to a voltage source, whereas the lower part 1 is immersed in an electrolytic bath in which the counterelectrode is located. During the subsequent flow of current, metal is then deposited at the locations at which the base metallization previously took place, with only the surfaces which are connected in an electrically conducting manner to the supporting frame being reinforced. Subsequently, the galvanic link 2 can be removed from the lower part 1. In FIG. 1, the lower part 1 after galvanizing is represented, with six contact elements 5 having been respectively deposited on the upper side and lower side of the lower part 1 for a 12-pin plug. The contact elements 5 are then connected via the interconnects 6 to the terminal elements 7, which are formed as metallized cylinder pins. The contact elements 5 and the lower edge 9 of the lower part 1 are slightly beveled in each case. For better connection of the galvanic link 2 to the supporting frame (not represented), said link is formed with matching clearances 10.
In FIGS. 3 and 4, the fully assembled plug 11 is respectively represented. Along with the already described lower part 1, the plug 11 comprises an upper part 12, which is made shorter than the lower part 1. The upper part 12 is in this case connected to the basic body 3 of the lower part 1. Before the upper part 12 and lower part 1 are put together, a printed circuit board 13, which can be seen in FIG. 3 through the depicted aperture in the upper part 12, is fitted into the lower part 1. The printed circuit board 13 is formed with metallized holes, through which the terminal elements 7 are led. As a result, the printed circuit board 13 is electrically connected to the contact elements 5. On the printed circuit board 13, functional modules 14 are arranged and leads 15 of a patch cable 16 are soldered. The printed circuit board 13 is then completely protected by the upper part 12 and the basic body 3 of the lower part 1. The remaining webs 17 of the removed galvanic link no longer have any functional purpose, but they are useful as an aid for introducing the plug 11 into the tapping contacts of the terminal block.
