Magazine

The invention relates to a magazine for insertion into disconnecting contacts of strips in telecommunications and data technology.

Such a magazine of the generic type is known, for example, from DE 10 2009 007 338 B3. One disadvantage with the known magazines is the fact that, for example, measurements at the disconnection point are no longer possible when the magazine is inserted.

The invention is based on the technical problem of providing a magazine which enables access to the signals at a disconnecting contact with few modifications to the design.

The solution to this technical problem results from the subject matter having the features of claim 1. Further advantageous configurations of the invention result from the dependent claims.

In this regard, the magazine for insertion into disconnecting contacts of strips in telecommunications and data technology comprises a housing and a printed circuit board, functional elements being arranged on the printed circuit board, and the printed circuit board being formed with tongues, the printed circuit board being mounted in the housing, the tongues protruding out of a lower side of the housing, the housing being connected to a separate cover, the cover being formed with openings, via which contact points on the printed circuit board or the functional elements are accessible. This makes it possible, using simple means, for a measurement to be performed in one line, for example. Simply by replacing the cover, it is possible in this case for a magazine to be matched in a simple manner to the required conditions. The cover is preferably latched to the housing. The functional elements on the printed circuit board can provide overvoltage protection, but can also be other active or passive functional elements such as filters, amplifiers, splitters or measurement and test devices, for example.

In the embodiment, further disconnecting contacts are arranged in the cover and are connected to the printed circuit board. This then provides the possibility of nevertheless dividing the line and possibly performing the measurement when the magazine is inserted. When the functional elements are in the form of overvoltage protection, the line therefore remains protected and it is nevertheless possible for a measurement to be performed. Alternatively, additional functional elements can be connected into the line via a plug. The disconnecting contacts in the cover are in this case accessible from the outside via the openings in the cover.

In a further embodiment, the cover is formed in at least two parts, comprising a cover upper part and a cover lower part.

In a further embodiment, the disconnecting contacts are each formed by two contacts, the contacts each having a longitudinal section, which longitudinal sections each have an upper and a lower hook-shaped end piece.

In a further embodiment, the contacts of a disconnecting contact are each inserted into a chamber from the front side and a chamber from the rear side of the cover lower part, the two upper end pieces and the two lower end pieces touching one another in the assembled state of the cover. This results in two contact points, with the printed circuit board being pushed between the two lower end pieces when the cover is placed onto the housing. In this case, the touching contacts can be such that virtually no contact force arises between the end pieces or else even a certain prestress occurs. In this case, provision can also be made for the end pieces not to touch one another in the assembled state of the cover and for touching contact between the upper end pieces only to arise by virtue of the printed circuit board being inserted between the two lower end pieces.

In a further embodiment, the cover upper part is formed with webs, which fix the contacts in the region of the longitudinal sections. This ensures that the contacts cannot be pressed out of the chamber. A further function of the webs is for said webs to represent a contact-pressure point when the printed circuit board is pushed between the lower end pieces. This builds up a corresponding contact-pressure force at the upper end pieces, with the result that a sufficient contact force is produced.

In a further embodiment, the chambers have V-shaped depressions at the sides, with the contacts being wider in the central region of the longitudinal sections than at the upper and lower end sections, with the wider regions lying at least partially in the V-shaped depression. The apex of the V-shaped depression can in this case also be rounded off. By virtue of the depressions, a movement of the contacts in the plug-in direction of a disconnecting plug is suppressed. Instead of the V-shaped depressions, other forms of a depression are also conceivable, with part of the contacts dipping into said depression in order thus to prevent a movement. For example, the depressions are rectangular and, correspondingly, the longitudinal sections of the contacts are formed with rectangular or similar projections.

In a further embodiment, the cover has guides and/or latching elements for a plug.

In a further embodiment, at least one grounding contact, which is preferably U-shaped, is arranged on the printed circuit board.

The invention will be explained in more detail below with reference to a preferred exemplary embodiment. In the drawings: figure 1 shows a perspective illustration of a magazine with a first cover, figure 2 shows a perspective illustration of a magazine with a second cover, figure 3 shows a perspective illustration of the first cover, figure 4 shows a perspective illustration of the first cover with the disconnecting plug inserted, figure 5 shows a perspective illustration of the second cover, figure 6 shows an exploded illustration of the first cover, figure 7 shows a perspective illustration of a magazine which has been inserted into a strip and has a first cover, figure 8 shows a perspective illustration of a magazine which has been inserted into a strip and has a second cover, and figure 9 shows a sectional illustration through the arrangements shown in figure 7.

Figure 1 shows a magazine 1. The magazine 1 comprises a housing 2 and a first cover 3. A printed circuit board 4 with overvoltage protection elements 5 (see figure 9) is arranged in the housing 2. The printed circuit board 4 is formed with notches in the lower region, with the result that tongues 6 are formed. These tongues 6 protrude out of a lower side 7 of the housing 2. Then, in each case two contact pads (not illustrated) are arranged on each tongue 6 on the front and rear sides. In this case, in each case one tongue 6 is used for connecting two disconnecting contacts 51 of a strip 50 (see figure 9), wherein the disconnecting contacts 51 are separated when the tongues 6 are inserted therein and contact is made between a contact limb of the disconnecting contact 51 and a contact pad on the printed circuit board 4. Furthermore, a grounding contact 8, which likewise protrudes out of the lower side 7 of the housing 2, is arranged on the printed circuit board 4. The grounding contact 8 is U-shaped in cross section, wherein only the two parallel limbs are shown in figure 1. The grounding contact 8 then makes contact with a grounding contact of a grounding rail, for example, said grounding rail being electrically connected to a mounting rack. The cover 3 is latched to the housing 1. For this purpose, the housing 1 has latching receptacles 9 and the cover 3 has corresponding latching hooks 10 (see figure 3). The cover 3 furthermore has openings 12 in its upper side 11, wherein it is possible for a disconnecting plug 13 to be inserted into said openings 12 into disconnecting contacts of the cover 3, for example, which will be explained in more detail further below. The cover 3 is stepped in cross section and has a higher side 14 with the openings 12 and a flatter side 15.

Figure 2 illustrates a magazine Γ with an alternative second cover 3'. The cover 3' likewise has openings 12' in its upper side 11', said openings having a different shape than the openings 12 shown in figure 1. Figure 5 illustrates the cover 3' on its own, with the result that the latching hooks 10' are shown. The printed circuit board 4 is accessible from the outside through the openings 12' and it is possible for measuring or test plugs to be inserted through said openings, for example, said measuring or test plugs then tapping off signals at contact pads on the printed circuit board 4, for example.

Figure 3 shows the cover 3 on its own without disconnecting plugs 13, wherein a guide 18 for the disconnecting plug 13 is illustrated by way of example on the front and rear sides 16, 17. Preferably, guides 18 are provided corresponding to the maximum possible number of disconnecting plugs 13 which can be inserted.

It should be noted here that the housing 2 has an identical design for both magazines 1, Γ, with the result that a magazine 1, Γ with different functionality can be provided merely by replacing a cover 3,3'.

Figures 6 and 9 will now be used to explain the design of the disconnecting contacts 34 (see figure 9) in the cover 3 in more detail. The cover 3 has a cover upper part 20 and a cover lower part 21, which can be latched to one another, for example. In this case, the cover lower part 21 preferably completely enters the cover upper part 20. The cover lower part 21 in this case has a substantially square basic structure. The housing lower part 21 has slots 22, which are aligned with the openings 12 in the assembled state. The slots 22 can extend from an upper side 23 of the cover lower part 21 as far as a lower side 24. Alternatively, the slot 22 can also be interrupted, in which case separate slots are arranged on the lower side 24 of the cover lower part 21. Chambers 27, into which contacts 28 are inserted, are arranged on a front side 25 and a rear side 26 of the cover lower part 21. In each case one contact 28 on the front side 25 and one opposite contact 28 on the rear side 26 form a disconnecting contact, wherein in each case two disconnecting contacts 34 are separated by a disconnecting plug 13 in an opening 12. The chambers 27 in this case each have a V-shaped depression 29 on the left-hand side and on the fright-hand side. Figure 6 shows, by way of example, two contacts 28 on the front side 25 and two contacts 28 on the rear side 26, which together form two disconnecting contacts of a disconnection point, which can be accessed via the opening 12 by means of a disconnecting plug 13. Furthermore, figure 6 shows an enlarged illustration of a contact 28. The contact geometry of the contact 28 will now be explained in more detail using this enlarged illustration.

The contact 28 has a longitudinal section 30, which is adjoined at its upper end by a hook-shaped end section 31. Correspondingly, a hook-shaped end section 32 is arranged on the lower end. The width B in the center of the longitudinal section 30 is greater than the width b at the end sections 31, 32. The increase or decrease in the width between b and B or B and b is in this case preferably continuous, further preferably monotonically increasing or decreasing. For example, the lateral contour of the contact 28 is likewise V-shaped. When inserted into the chambers 27, the contact then lies with its wider portion in the V-shaped depressions 29 of the chamber 27. This prevents the possibility of the contact 28 being shifted in the longitudinal direction L of the slot 22.

Figures 7 and 8 illustrate the magazine 1 and T, respectively, in the assembled state with a strip 50 in telecommunications and data technology. In this case, the strip has a row of disconnecting contacts, into which the tongues 6 of the magazine 1 and Γ are inserted. Figure 9 shows a sectional illustration through figure 7, with the section passing through the disconnecting plug 13.

As illustrated in figure 9, a tongue 6 of the printed circuit board 4 of the magazine 1 is inserted into a disconnecting contact 51 of the strip 50. The opposite end of the printed circuit board 4 lies between two lower end sections 32 of the contacts. Webs 33 of the cover upper part 20 in this case fix the contacts 28 approximately in the center. It should be noted here that the illustration shown in figure 9 does not show the deflections of the contacts 28. Correctly, the end section 32 rests on the upper side of the printed circuit board 4 and the end section 32 of the lower contact 28 bears against the lower side of the printed circuit board 4. In the process, the end sections 32 preferably make contact with contact pads arranged on the printed circuit board 4 on the upper and lower side, said contact pads not being through-plated. The electrical circuit is then closed by the closed disconnecting contact 34, which is formed by the two upper end sections 31. Likewise, the longitudinal section 30 is below (for the upper contact 28) or above (for the lower contact 28) the webs 33 in the region of said webs 33. Correspondingly, the end section 31 of the upper contact 28 rests on a tongue 35 of the disconnecting plug 13 or the end section 31 of the lower contact 28 bears against the lower side of the tongue 35. The above statements also apply to the illustration of the disconnecting contact 51. The contacts 28 are moved away from one another by the printed circuit board 4 between the end sections 32, wherein the contacts 28 cannot be deflected upwards or downwards owing to the webs 33. As a result, a force is built up in the contacts 28 which pushes the upper end sections 31 against one another. The two upper end sections 31 of the two contacts 28 which are pressed against one another then form the disconnecting contact 34 in the cover 3, into which the tongue 35 of the disconnecting plug 13 is inserted in figure 9.
