Holder for overvoltage C-asent charge arrester

The! Inflation is related to a holder for tTberspan «· voltage gas discharge arrester in button form ("button arrester")) especially for use in learning speaker systems,

The task of the fire is to create such a To train holder so that it consists of a small number of simply designed items and with a few simple steps can be mounted.

This object is achieved according to the invention in that the flat holder has two with a recess for has the arrester provided insulating material, between which the connection contacts are arranged and on which a irerriegelbaren pressure piece is pivotably mounted, which means a leather on a connecting contact piece acts and the necessary .KontaktÄxuck between the connection contacts, the

^ x1133 = £ P (7)

Arresters and the connecting contact piece produces.

According to a "particularly useful embodiment of the ! Price increases, the holder is designed so that it has two for protection a two-wire line (for example the a, b-wires of a telephone line) can accommodate certain arresters. at In such a configuration of the fire, the two arresters are based on one each with a wire of the one to be protected Connection contact coming into contact abä £ S £ 2SS, while the two arresters are common, from above atif the arresters Pressed "connecting contact piece in current-conducting connection with a middle connection contact lying on earth stands.

These and other details of the innovation can be found in the following description of one illustrated in the drawing Embodiment emerges. Show it:

Fig. 1 is a longitudinal section through the innovation according to the invention Holder along line I-I of Figure 2;

Pig. 2 shows a cross section through the holder along the line IT-II of the Pig. 1.

The holder shown is used to hold two button-shaped overvoltage gas discharge arresters, so-called "Button arresters. The holder essentially consists consisting of two insulating plates, a pressure piece

and a locking pawl 7.

Between the two insulating plates 4 and 5 made of thermosetting plastic "three connection contacts 8 _f 9" and 10 are arranged. The connection contacts 8 and 9 sit on peg-like projections 4 a of the insulating material plate 4.

In the holder 1, a connecting contact piece 11 is also provided, that at both ends with recesses 11a in the Button arrester 2 and 3 engages. Support in these indentations two Sehraub spring down 12 and 13, which are in recesses 6a and 6b of the pivotable pressure piece 6 are housed.

These coil springs 12, 13 produce the contact pressure between the connecting contact piece 11 and the button conductors 2, 3 and the central connection contact 10 and the contact pressure between the button conductors 2, 3 and the two other connection contacts 8 and 9.

The connection of the two insulating material plates 4 and 5 takes place via three meters 14, 15, 16, of which the Iiet 14 is also the pivot bearing point for the locking pawl 7 and the Uiet 15, the pivot bearing point for the pressure piece 6 forms. The button arresters 2 and 3 sit in recesses 17, 18 of the insulating panels 4 and 5. These recesses are like those from Pig. 1 emerges - open at the top, so that the

Head 2 and 3 after swiveling up the pressure piece 6 comfortably can be exchanged.

The connection contacts 8 and 9 come when the Halters on a telephone distribution facility with the two wires of the line to be protected against overvoltage in contact, while the middle connection contact 10 to earth located. The two outer lugs 19 and 20 of the holder 1 are used for guidance when placing the holder. The plugging in and Pulling out the holder 1 is facilitated by the corrugation 21, 22 provided in the outer region of its two narrow sides.

Claims (6)

RA. 836172 * 11/27/64 Safety requirements 1, Holder for surge arrester in the form of a button ("Button arrester"), especially for connection in telephone distribution systems, characterized, that the flat holder has two insulating material plates provided with a recess (17, 18) for the arrester (2,3) (4,5), between which the connection contacts (8,9,10) are arranged, on which a lockable Druekstüek (6) is pivotably mounted, which by means of a leather (12,1-3) a connecting contact piece (11) acts and the required Establishes contact pressure between sowing connection contacts, the arrester and the connecting contact piece. 2. Holder according to claim 1 for receiving two arresters intended to protect a two-wire line, thereby ■ indicates that see the two arresters (2,3) on one each comes into contact with a core of the line to be protected Support the connection contact (8, 9), while the connection contact piece which is common to the two arresters is printed onto the arrester from above (11) is in current-conducting connection with a central connection contact (10) lying on earth. ■ 3. Holder according to claims 1 and 2, characterized in that that the connecting contact piece (11) at its ends with each a recess intended for engagement in the arrester (2, 3) " (11a) is seen in which dxe is in recesses (6a, 6b) of the swiveling pressure piece (6) housed beds (12,13). 4 _f holder according to claims 1 and 2, characterized in that one of the two from '. Thermosetting plastic insulation plates (4 »5) peg-like gate projections (4a) for holding the connection con t alrfc e (8,9) provided with a corresponding hole. 5. Holder according to claim 1, characterized in that the locking of the pivotable pressure piece (6) by a likewise Locking pivoted on the insulating plates (4,5) sklinke (?) is formed, 6. Holder according to claims 1 and 5 ,. characterized in that the two insulating plates: (4 ₉ 5) are connected to each other by liets (14,15,16) which at the same time form the pivot bearing points for the pressure piece (6) and the locking pawl (7).
