Abstract

The invention relates to an overvoltage protection magazine (10) for a device used in telecommunications engineering, comprising a housing (12) with a front, back, top and bottom side and several tapping contacts (20) which extend along a section (32) from the rear side of the housing and, once mounted, tap contacts of the device used in telecommunications engineering. The invention also provides for at least one earth terminal (16) and several overvoltage protectors (14) which can be inserted into the overvoltage protection magazine (10) and comprise terminal pins (22) which when inserted are directly connected to the contacts (20) in an electrically conductive manner. To save space the overvoltage protectors (14) can be inserted into the magazine (10) alternately from above and below so that the terminal pins (22) in their inserted state extend either towards the bottom or the top in such a way that, viewed from the front side, they are staggered in relation to each other.

Description

Surge protection magazine for a facility for telecommunications technology

Technical field

The invention relates to an overvoltage protection magazine for a device in telecommunications technology according to the preamble of claims 1 and 4.

Surge protection magazines are widely used in telecommunications technology, which are placed on devices, for example terminal strips, of telecommunications technology in order to protect electronic components or devices which are connected to said device from overvoltages. Conventional protective magazines, in contrast to individual plugs assigned to protective plugs, have a plurality of surge arresters and are also designed such that they can be plugged onto the mostly strip-shaped devices of telecommunications technology in such a way that the applied voltage is tapped from all contacts of such a device. For this purpose, known surge protection magazines have a plurality of contacts which extend with a section from the rear of the surge protection magazine, that is to say the side which is directed toward the connection device, and which, when fitted, tap the contacts of the device for telecommunications technology. Surge arresters, which can be inserted into the surge protection magazine, are connected in an electrically conductive manner to these tapping contacts, so that an overvoltage present at the tapping contact of the surge protection magazine is also present at the individual surge arrester. When a certain voltage is exceeded, the surge arrester trips and discharges the electrical energy to earth. For this purpose, the overvoltage protection magazines described have an earth contact that extends out of the housing and is connected to earth.

State of the art

An overvoltage protection magazine according to the preamble of claim 1 is known from DE 30 14 796 C3. Here, surge arresters are inserted in a number that corresponds to the number of double wires that can be connected to the associated connection device, from one housing front side next to the other in the surge protection magazine. The surge arresters are wired components that have so-called legs, which are directly connected to the tapping contacts of the surge protection magazine in an electrically conductive manner. For this purpose, both the tapping contacts and the ground contact are bent into a U-shape at those sections where they contact the legs of the surge arresters, so that the legs of the surge arresters make electrical contact on the inner surfaces of the U-shaped regions of the tapping contacts become.

The shape of both the tapping contacts and the earth contact is comparatively complicated. This is because the bending edges for the formation of the U-shaped region are not parallel to those bending edges which are provided in the further course of the contacts for the formation of those sections with which the contacts of the connection device are tapped off. Thus the Production of the tapping and earth contacts of such an overvoltage protection magazine is complex due to the necessity of bending processes around bending edges that are not parallel to one another.

Furthermore, in this known surge protection magazine, the size of the magazine is necessarily due to the space required by the side by side

Surge arrester determined. In other words, the width of such a surge protection magazine cannot be made smaller than the dimension of the surge arresters arranged next to one another in the required number. This known overvoltage protection magazine thus limits the possibility, owing to the defined size, of reducing the space required for the telecommunications technology equipment, including the overvoltage protection magazine placed thereon.

From DE 31 13 759 C2 is one

Surge arrester device for isolating strips is known, in which a plurality of wired surge arresters can be used from the top of the housing, the legs of the surge arrester only being connected to the tapping contacts in an electrically conductive manner, namely via so-called clamp receptacles. Due to this fact and due to the comparatively large size of this known magazine, it is also in need of improvement.

A protective plug for connection and isolating strips, which has several non-wired surge arresters, is known from DE 42 25 484 C1. The non-wired, largely cylindrical surge arresters are contacted by a contact cage. However, this is necessarily designed to be complicated and, moreover, is not suitable for contacting wired surge arresters which are to be used in a generic manner. This applies in the same way to the magazine known from DE 34 30 922 AI, which has a printed circuit board through whose contact tracks the contacts of the connection device are tapped. Because of the necessity of a printed circuit board, this known magazine is economically disadvantageous.

Presentation of the invention

The invention has for its object to provide a generic surge protection magazine that has a simple structure so that it can be manufactured with little effort, and which can also be made particularly small.

This object is achieved on the one hand by the overvoltage protection magazine described in claim 1.

Accordingly, the tapping contacts with which the legs of the surge arresters are directly connected in an electrically conductive manner are designed in such a way that they have a contact slot which is defined by two contact legs which lie largely in one plane. As a result, complicated bending operations can be avoided for the tapping contacts, since the contact slot is not formed by bending a strip-shaped section into a U-shape, but rather by punching out the contact slot in the strip-shaped contact. Thus, two sheet metal strips lying largely in one plane, which represent the contact legs, define the contact slot between them. The direct contacting of the legs of the surge arrester between the two contact legs advantageously avoids a printed circuit board, so that the manufacturing outlay for the surge protection magazine according to the invention can be kept low. In addition, the tapping contacts designed in the manner described can be particularly easily by simple Manufacture punching and bending processes, which can in particular take place around mutually parallel edges.

In the first embodiment of the invention, the surge arresters can be inserted into the magazine from the front of the housing in the direction of their legs in such a way that the legs extend in a direction largely perpendicular to the contact slot in the magazine. Such contacting of the legs of wired surge arresters is a new measure for a surge arrester magazine. As will be explained in more detail below, the entire structure of the surge protection magazine can be considerably simplified.

In the present embodiment, the described insertion direction from the front of the housing also enables the surge arresters to be located alternately at at least two different levels with regard to the depth of the surge protection magazine in the inserted state. In other words, the surge arresters are arranged offset from one another when viewed from the top. With this approach, the largely cylindrical surge arresters can be recognized as circles. In the conventional surge protection magazine of the generic type, all centers of these circles lie on one line, so that the space requirement is determined by the sum of the diameters and cannot be reduced further.

According to the invention, the individual surge arresters, viewed from the top, are arranged offset from one another in such a way that their centers are on a zigzag line. As a result, the width of the magazine can be reduced, so that considerable space savings are made possible in connection with appropriately designed connection devices in telecommunications technology. To this end, the Tapping contacts, which are the contacts of the

Tap connection devices, alternately different distances towards the front of the

Surge protection magazine, so that the surge arresters inserted at different distances from the front can be contacted. In this embodiment of the surge protection magazine according to the invention, a space-saving design of the magazine is thus ensured with a simple construction.

Preferred developments of this first embodiment of the invention are described in the further claims.

Preferably, the front of the housing can be closed by a removable cover, so that the fully loaded magazine gives a complete impression, and the surge arresters used and the contacts and arresters housed in the magazine are protected from dirt.

A particularly simple construction also results if the overvoltage protection magazine has an earth rail to which, in the inserted state, one contact of the overvoltage arrester is directly connected in an electrically conductive manner. In other words, the basic idea of a direct electrically conductive connection of the legs of the surge arrester with the tapping contacts is also transferred to the earth contact in the form of an earth rail, so that any intermediate contacts or circuit boards required in the prior art can also be avoided in this area.

On the other hand, the object on which the invention is based is achieved by the overvoltage protection magazine according to claim 4.

In this embodiment of the invention, too, the size of the overvoltage protection magazine becomes more advantageous Reduced way compared to the magazines known in the prior art in that the surge arresters can be inserted offset in the magazine. In this embodiment, the basic idea of the invention is realized in that the surge arresters can be inserted into the magazine alternately from the top and bottom, the legs extending in the inserted state in each case to the bottom or top. Thus, the offset of the surge arresters can be seen from the front in this embodiment. In this direction, the surge arresters, which can be used from above or below in the direction of their legs, appear as circles. Similar to the embodiment described above, only rotated by 90 °, the circular surge arresters, viewed from the front, are offset from one another and arranged with their centers on a zigzag line. The legs of the surge arresters inserted from the top extend between two adjacent surge arresters inserted from the bottom.

In this embodiment of the invention as well, the need for a printed circuit board or intermediate contacts can be avoided by the preferred measures described below. In addition, in this embodiment, too, the overall size can be significantly reduced compared to the prior art, in that the width of the surge protection magazine compared to the sum of the diameters of the surge arresters used can be reduced by the offset described.

In the embodiment of the invention described last, the earth contact of the magazine is preferably electrically conductively connected to a strip-shaped earth rail, the sheet metal plane of which is at an angle of approximately 90 ° to the sheet plane 8th

Earth contact runs. As a result, the earth rail can be connected to the at least one earth contact in a simple manner by clamping.

In this case, the use of intermediate contacts for connection to the earth rail has proven to be particularly advantageous.

In the last-described embodiment, too, it is preferred for the tapping contacts and / or the intermediate contacts that they are provided with contact slots which are formed by two strip-shaped contact legs lying in one plane! are limited. The contacts designed in this way can be produced by stamping and a simple bending operation and allow a reliable, directly electrically conductive connection of the legs of the surge arrester to the contacts.

As is the case with the first embodiment, it is further preferred that the legs of the surge arresters can be inserted into the contact slots parallel to the latter. This previously unknown orientation of the pins to the contact slots in the technology for surge protection magazines, which becomes even clearer from the following description of the preferred exemplary embodiments with reference to the drawings, that the overall structure of the surge protection magazine can be simplified.

To compensate for tolerances on the contacts provided with the described contact slots, it is advantageous if a constriction is formed adjacent to at least one contact leg. As a result, the area of the contact slot can tilt a little elastically overall, so that manufacturing tolerances can be compensated for, and a safe electrically conductive contacting of the legs is always made possible. As already mentioned, it offers for everyone

Embodiments of the invention have considerable advantages if the tapping and / or intermediate contacts used are designed as sheet metal elements which are provided with at least one bend parallel to the sheet metal plane. As a result, the contacts can be brought into the shape with little effort, which is necessary for contacting both the contacts to be tapped on the connection device and the legs of the surge arrester. In the case of a multiple bend, all of the bending edges can be aligned parallel to one another, which simplifies production.

Finally, for the safe and positionally accurate insertion of the surge arresters, there are advantages if guides for the legs of the surge arresters are provided in the housing of the surge protection magazine. This ensures the correct arrangement of the legs, in particular in the described alignment of the legs parallel to a contact slot delimited by two strip-shaped contact legs.

the surge arrester 14 attached bracket 28 around a conventional fail-safe device.

1 also shows the novel, offset and therefore particularly space-saving arrangement of the surge arrester 14 in the surge protection magazine 10. As can easily be seen, in a conventional arrangement of the surge arrester 14, in which the center points or cylinder axes, that is to say the respective upper end of the leg 22 shown in FIG. 1, are on a line, the width of the surge protection magazine 10 limited by the sum of the diameters of the surge arresters 14. In addition, since the individual surge arresters 14 have to be separated from one another, and if necessary partition walls have to be formed between them, the width of the

Surge protection magazine 10 can not be reduced below a certain value. A narrowing is made possible according to the invention, however, in that the surge arresters 14 alternate at different depth levels, i.e. are at a different height as shown in FIG. 1. As a result, the surge arresters 14 can be moved closer together as viewed in the width direction. Furthermore, because of the greater distance between the surge arresters 14, partition walls can be dispensed with, which also has an advantageous effect on the required structural size.

In the space between two surge arresters 14 on the rear level, as shown in FIG. 1, the lower level, the legs of the surge arrester 14 arranged therebetween are located on the front level and the tab of the earth rail 26 extending to the leg 22 Space requirements can be significantly reduced by simple structural measures.

32 of the tapping contacts 20, which extend into the (not shown) device of the telecommunications technology, onto which the overvoltage protection magazine 10 is attached during use. In the plugged-on state, it is moreover in an orientation rotated by 90 ° with respect to the orientation of FIGS. 3 and 4. For the sake of simplicity, the overvoltage protection magazine 10 is shown upright in FIGS. 3 and 4 as well as in FIG. 1, so that the "rear" level appears as the lower level.

As can be seen in FIG. 3, the tapping contact 20 consists of the narrow, strip-shaped tapping section 32 described, which extends to the rear of the housing. In this area, a web 38 is formed, which extends to the section 36 with the contact slot 40 serving for the insertion of the leg 30. The sheet metal plane is bent between the tapping section 32 and the contact section 36, as can be seen in FIG. 2, so that the contact section 36 is inclined to the drawing plane of FIGS. 3 and 4. The tapping contact 20 is particularly simple, so that no further bends are required, but that the contact slot 40 is defined by two flat, largely strip-shaped contact legs 42 which lie in one plane and can be easily formed when punching the tapping contact 20 .

The leg 30 of the surge arrester 14 is inserted parallel to the contact legs 42 into the contact slot 40, the insertion movement being supported by guides, not shown, which are formed in the housing of the surge protection magazine 10. Consequently, the construction of the surge protection magazine 10 according to the invention is particularly simple, since no circuit board and no complicated bends of the tapping contact 20 are required for connecting the legs 30 to the tapping contacts 20. The middle leg 22 is also shown in FIG. 3 o Φ <J tr tr <! <ö Φ MP tr PJ ≥; ≤ o? ti CQ CQ α <<3 ≤ zt? d P. PJ tr φ 03 P. tr P φ Φ Φ Φ P Φ PPPP P- P P- φ JZ Φ Φ Φ 0 0 P- p- φ t! Φ Φ C Φ P- Φ Φ
