BACKGROUND - :
Bu . The invention relates to a protectivve plug for connector or dieconnector banks of telecommunication systems provided with a collective earth connection according to the : preamble of claim 1. + A protective plug of the mentioned species is : : ! \ 19 known. . This protective plug comprises two half 3 : ghells of housing, in the interior of which a
Cor . protective hybrid with two parallel conductive : , _ pathe is arranged. The conductive paths are Co , connected over conductor contacts with the a-b wires or a - Db’ wires, Treep., of the . telecommunication line. Further, overvoltage : suppressors arranged side-by-side are provided
Co : being held between conductive pathe of the ! : protective hybrid and an earthing sheet. the : . ‘20 earthing sheet arranged underneath the oo protective hybride comprises for holding the oo ‘iy by - oe ! , - . : .
R. Cu ; Co :
Sh Te Po , . Ct overvoltage suppressors two resilient sheet- metal tongues being angled to form U-shaped clamps laterally to the longitudinal eides of the earthing sheet. In order to connect the overvoltage BUPPressors to earth, two additional sheet-metal tongues are required. , these sheet-metal tongues comprise one leg each being spaced relative to the conductive paths.
It is dieadvantageous, with this protective 19 plug, that by the arrangement of two eide-by- side overvoltage suppresgeors and by the earthing sheet including several eheet-metal tongues, the width and the thicknese of the housing are increased considerably.
When inserting the protective plug into a connector or disconnector bank, thus the wiring side of the bank is hidden euch that for connecting or diegconnecting (wiring) cable wires, firet the protective plug has to be pulled out. Another disadvantage is that the houeing of the protective plug is formed ae two-piece housing. - 2 _ i
The invention 'is based, therefore, on the . object to provide a protectivve plug of the : : aforementioned species, the housing of which is as small as poesible and in which the cables connected on the wiring eide of a connector or . disconnector bank are accesslble even after insertion of the protectivve plug.
The solution for this object results from the characterizing features of claim 1. The - 19 overvoltage suppressors are contacted with the
Co collective earth connection only after mounting
EE : | the protegtive plug on a connector. or - a _ disconnector bank, thus an earth connection : I a SEE being formed. According to the invention, the
LT RE | 15 collective earth connection is arranged outside , the housing of the protective plug, thus the ! housing “being substantially reduced in elze.
Co : : By reducing the housing size of the protectivve ’ plug, the cable wires connected on the wiring ; 20 side of the connector or disconnector bank are . accesslble even after plugging the protective ' plug on euch that wiring operations, e.g. 3. ¢ } ’ ) i : , oo loosening cable wires connected already, is } possible even without removing the protective rlug. Furthermore, the protective plug is constituted of a one-piece housing such that it can be manufactured much more economically. . Further advantagesous embodiments of the invention result from the subclaimes.
Particular attention should be directed to the embodiment according to claim 8, 7 and 8, } wherein the luge of the collective earth connection for contacting the overvoltage
BUPPressors exhibit a short length only.

According to Fig. 5, the connector or disconnector bank 4 made of plastic is plugged on lugs 37 of a metal mounting bracket 36 connected to an earth line and 1s engaged therewith. Such a connector or disconnector bank to be latched on a mounting bracket 36 consists of a lower part and of an upper par? latched therewith. At the connector or 12 disconnector bank, at the one side (cable side) the cable wires 38 coming from the subscribers, and on the other side (wiring eide) the wires 39 leading to exchange installations are connected to insulation dieplacement contact pleceg 489, 41 disposed in two rows. The insulation dieplacement <ontact piece 49 of the one row is connected over a fork-type contact plece 47 to the insulation displacement contact piece 41 of the other row.
In parallel to the ¢onnector or disconnector bank 4, a metal collective earth connection 5 : ig plugged on. The collective earth connection comprises at the front sides two fork-type contact pleces 57 engaging over the lugs 37 of the mounting bracket 36 and connecting, thus, : the collective earth connection 6 electrically 5 to the mounting bracket 36.
The collective earth connection 5 comprises several lugs 11 with interposed slots 42. Per double wire 9a-b wire), one lug 11 ie provided. oo In cage an overvoltage protection is required
Co 19 for the cable wire 38 connected to the oo connector or disconnector bank 4, then for each - cable wire one protective plug 1 ie inserted . into the bank 4 between the two rows of. } '
Co insulation dieplacement contacte 49, 41 into . Co 15 the fork-type contact 47. The latch 43 of the " = : - insertion section 18 of the protective plug 1 ! Co enEagen, here, into the: bank a. The fork-type + oo , contacts 47 engage over the conductor contact

collective earth connection engages into one insertion channel 48 of a protectivve plug 1.
In the firet embodiment of the protectivve plug 1 (Fige. 1 to 4), the luge 11 press the hooks 6, 7 holding the overvoltage suppreescre 3 away ~- as shown in Fig. 4 - and contact the one pole side 28 of the overvoltage euppressors 3 being, thus, connected to earth. The overvoltage suppressors 3 are pressed hy the resilient 19 conductor aontact pleces 13, 14 against the luge 11 of the collective earth connection 5, thus a safe contacting hetween the lugs 11 snd the pole side Z8 of the overvoltage suppressors 3 being mschieved. When pulling the protective plug 1 out off the connector or disconnector bank 4, the latch hooks B, 7 engsge =sgain behind the one ploe elde 28 of the overvoltage suppressors 3 and fix them again in the housing 2 of the protective plug 1. :
In the second embodiment of the protective pluf (Figs. 5 to 11), the lugs 11 cover one half
. each of the front eide 18 of the protective plug 1 guch. that the slot 42 disposed between the lugs 11 extends centrally on the longitudinal axis 9 of the protective plug 1 and receives the latch hooks 6, 7 and the guide piece 35 of the central piece 33. For a better guiding of the lugs 11, two additional guide pleces 44 are arranged at the front side 10 ‘of the narrow sides 4b. 19 The the third embodiment (Figs. 12 to 16), the lugs are, when inserting sthe protective plug 1 into the insertion channel 48, pressed under ' the shoulder pleces 24, as shown in Fig. 12.
In order to facilitate the insertion, the lugs 11 are, in this embodiment, glightly bent off + : at the front side 46. | :
In the fourth embodiment (Figs. 17 and 18), the oo lugs 11 are provided with a shorter length relativve to the embodiments described oo previously, as the lug 11 in this embodiment needs only be connected electrically with the Co sheet -metal part HA. For gniding the Ing 11, one guide angle 53 ench ie provided at the longitudinal elded 8 of the housing 2 guch that in the ingertion channel 48 the 1g 11 of the collective earth connection 5 16 arranged between the guide angles 53 and the sheet-metal part 50.
The case geyveral protective plugs 1 are connected gide-by-side at the longitudinal 19 sides 8, Aa protective plug bank 31 is formed.
In the following, the overvoltage CAaee le briefly deecribed. In «ase an overvoltage occurs, the overvoltage or the overcurrent, resp. , ie conducted over the cable wires 38, 39, the itnegulation displacement contacts 49, 41, the fork-type contact 47, the conductor . contacts 13, 14, the melt bead 3@ to the one pole side 29 of the overvoltage suppressor 3.
