Abstract
The connector (1, 4) is a small elongate printed circuit board, having at one end plug-in tongues (5) which can be inserted between contact springs (10) of a distribution board. insulation piercing connecting devices (4) are soldered to the circuit board (1) to lie flat for the connection of electrical lines to contact pads (3) formed on tongues (5) via conductor tracks (2) on the circuit board (1). The connection and disconnection of the lines to and from the insulation piercing connecting devices (4) is so simple that the connector can be used for change-over operations in the exchange. <IMAGE>
Description
Connector for distribution boards of telecommunication systems.
The present invention relates to a connector for distribution boards of telecommunication systems, in particular for telephone systems, the distribution board having switch or break contacts between which the connector with corresponding opposite contacts can be inserted. A connector of this kind is described, for example, in German utility model number 81 22 459. The elongate, three-pole, flat connector comprises a small circuit board which ends in three plug-in tongues. The contacts at the ends of these tongues are designed as contact sufaces from where conductor tracks lead to the other end of the small circuit board, where wires of a flexible cord are soldered on and surrounded by a connector housing.
Connectors of this type with connected leads are used for instance for testing purposes.
Insulation piercing connecting devices with two separate clamping slits are commonly used as connection elements in distribution systems. Insulation piercing connecting devices of this kind are described, for example, in German Patent Specificaton 20 20 103.
Here two jumper wires can thus be connected simultaneously, which facilitates changing over or rewiring without interruption. To save costs, however, of late single-part insulation piercing connecting devices with one clamping slit are being used. An insulation piercing connecting device of this kind is described, for example, in
Geman Offenlegugschrift 33 11 447. It is not possible in this case, for example, to change from an old to a new switching system without interruption of the systems functioning.
An object of the present invention is to enable a rapid changing over of all subscribers to a new system, without interrupting the subscriber service.
This object is achieved, according to the invention, by.
The changeover to the new system is made by first inserting the safety connector between the switch contacts of the individual subscriber lines and immediately connecting the associated lines leading to the old switching system to these connectors. The safety connector is designed so that it only makes contact with the line coming from the subscriber. This preparatory work is carried out step by step, without resulting in any major interruptions to individual subscribers. In the meantime, for example, the lines leading to the new switching system can be connected to the contact elements that have become free. The connector separates the switch contacts so that no connection between the subscribers and the new switching system is made at this time.When the new exchange is to be switched in, all that is necessary is to pull out all the changeover connectors, which takes very little time. The switch contacts then close, connecting each subscriber to the new exchange.
The connector according to the invention is designed in such a manner that the same circuit board can be used as, for example, for a two-tongued test connector. As with the distribution board itself, insulation piercing connecting devices to which the insulated jumper wires can be connected without baring the wires serve as connection elements. This has the advantage that the same tool can be used for this as for the insulation piercing connecting devices of the distribution board. The insulation piercing connection device is connected in a simple manner to the associated conductor track by means of soldering.
According to an advantageous further development of the invention, the insulation piercing connecting device has a solder spine extending towards its associated contact and lying against the corresponding conductor track. The width of the solder spine can be matched to the width of the conductor track in such a manner that a reliable connection is established.
According to another further development of the invention, the insulation piercing connecting device is riveted to the circuit board. This makes the mechanical connection to the circuit board particularly reliable and stable. Riveting takes place before soldering, the insulation piercing connecting device being fixed securely and centred on the circuit board.
According to another further development of the invention, the circuit board underlies the entire insulation piercing connecting device and is provided in the area of clamping slit of each respective insulation piercing connecting device with a slit-shaped clearance for the insulated wire. These slit-shaped clearances can be made so narrow that the insulated wires are clamped into them and relieved of strain. Since it is fixed to the circuit board over its entire area, the insulation piercing connecting device can be supported over a wide area on the circuit board right into the clamping area.
An embodiment of the invention will now be explained in more detail with reference to the drawings, in which:
Figure 1 shows a side view of a connector for the changeover of distribution systems,
Figure 2 shows a top view of the connector according to
Figure 1,
Figure 3 shows a schematic diagram of a break contact of the distribution system with existing connected lines and new lines to be connected,
Figure 4 shows the break contact of Fogure 3 with a connector of Figure 1.
Referring to Figures 1 and 2, a connector 14 for the changeover of distribution system consists of an elongate circuit board 1 with conductor tracks 2, contact pads 3 and an insulation piercing connecting device 4. The contact pads 3 are designed as widened end surfaces of the conductor tracks 2 on plug-in tongues 5 extending longitudinally at one end of the circuit board 1. The insulation piercing connecting devices 4 are soldered onto the conductor tracks 2 at the other end of the circuit board 1 and are secured to the circuit board 1 by means of a rivet 6. The insulation piercing connecting device 4 is provided with a clamping slit 7 into which an insulated jumper wire can be clamped to make a contact without previously having to bare the wire.The circuit board l is designed to be so long that it fully covers the insulation piercing connecting device 4 up into the area of the clamping slit 7.
Referring now to Figure 3, a wire of a subscriber line 8 is connected to a connection element 9 of a distribution board. The connection element 9, which is designed as insulation piercing connecting device, is connected to a contact spring which together with another contact spring 10 forms a break contact 11. The other contact spring 10 is connected via a further connection element 9 to a line 12 which leads to the switching system a which is to be replaced. In the vicinity of this connection element 9, a new line 13 leading to a new switching system n has already been laid. The line 12 leading to the old exchange a can now be removed from the associated connection element 9 in accordance with the dashed line.
As shown in Figure 4, this line 12 is then immediately connected to the insulation piercing connecting device 4 of the connector for the chageover. This connector is inserted with its opposite contacts 3 between the poles of the break contact 11, whereby the contact springs 10 are separated. The connector is inserted in such a manner that the two lines 12 and 8 are electrically connected to each other via the insulation piercing connecting device 4, the conductor track 2, the contact pad 3 and the associated contact spring 10. The new line 13 is then connected to the corresponding insulation piercing connecting device 9 in the place of the old line 12.
After all subscriber lines 8 have been led via the connectors to the old switching system a, the entire distribution board can be switched over to the new switching system n within a short time by pulling out the connectors. The old switching system a is thereby disconnected, and the new switching system connected at the same time.
