Abstract

The automatic multi-way cable tester is suitable for checking continuity of telephone cable connectors and other multi-pole connectors. A pulse unit constructed from integrated circuit TTL logic modules comprises a bistable multivibrator and a number of shift-registers. The test pulse appears at each of up to 50 output points in sequence. The pulses are applied to one side of the unit under test. The other side is connected, via a multipole adapter, to a visual display unit. This is constructed from LEDS each with its own series resistor. A diode indicator is connected into each electrical path of the specimen so that as the test pulse is applied to each in turn, the continuity can be observed from the energised diodes.

Description

Betr, Antrag auf ein Patent für ein Kabeiprüfgerät 1.) Patentansprüche: Oberbegriff: 1 Kabelprüfgerät für Reihen- und Kurzschlußmessungen. Re, application for a patent for a cable testing device 1.) Claims: Generic term: 1 cable tester for series and short circuit measurements.

Kennzeichnender Teil: Das Kabelprüfgerät besteht aus zwei abhängigen Teilfunktionen, worin der eine Teil die Steuerung, und der andere Teil die Anzeige übernimmt Oberbegriff des Unteranspruches 2, = siehe 1. Characteristic Part: The cable tester consists of two dependent Sub-functions, in which one part is the control and the other part the display takes over the generic term of dependent claim 2, = see 1.

kennzeichnender ieil des UnteransSruches: Das Kabelprüfgerät kann je nach Aufgabe auf unbestimmte Zahl der Prüffunktionen erweitert werden. Characteristic part of the sub-claim: The cable tester can can be extended to an indefinite number of test functions depending on the task.

1. Bezeichnung: Kabelprüfgerät mit Anzeigesystem 2. Anwendungsbereich: Durchmessen der einzelnen Adern auf Adernschluß und auf die richtige Reibenfolge 3. Zweck: Auf dem Gebiet der Nachrichtentechnik (spez. Sprechanlagenbau) gibt es sehr viele Anlagen, die ein großes Kabelnetz brauchen. Durch die Empfindlichkeit der modernen Ablagen wird das wabelnetz vorher ausgemessen.1. Designation: Cable tester with display system 2. Area of application: Measure the individual wires for wire connection and the correct sequence 3. Purpose: In the field of communications engineering (special intercom construction) there is a lot of systems that need a large cable network. The sensitivity The honeycomb network of the modern shelves is measured beforehand.

Störungen im Kabelnetz sind zeitrautend und kostspielig.Disruptions in the cable network are time-consuming and costly.

4. Aufgabe: das von mir entwickelte Gerät hat die Aufgabe, die zu messenden Adern auf Kurzschluß, bzw. übergangswiderstände bis 2o k o, und Vertauschungen optisch anzuzeigen. Mit Adapterkabeln ist dieses Gerät vielseitig einsetzbar und zeitsparend.4th task: the device developed by me has the task of measuring wires for short circuit, or contact resistance up to 2o k o, and interchanges to be displayed visually. With adapter cables, this device can be used in many ways and time saving.

5. Beschreibung zu Fg. 1 # 2: Adapterstecker oder Prüfstecker vom Gerät 2 einseitig mit dem Prüfungsobjekt verbinden. Prüfobjekte können sein: Fernsppechleisten, Fernsprechkabelenden, Anschlußdosen usw.5. Description of Fg. 1 # 2: Adapter plug or test plug from Connect device 2 to the test object on one side. The test objects can be: telecommunication strips, Telephone cable ends, junction boxes, etc.

Gerät einschalten. Gerät 1 anderseitig anschließen und prüfen.Turn on a device. Connect device 1 on the other side and check.

Dieser Prüfvorgang geht wie folgt: Gerät 2 erzeugt im raktabstand von 1-10 Sek. (einschaltbar) einen impuls, der eine bistabile kippstufe setzt. kiese Stufe Eilt auf die angeschlossene Ader ein H-Signal, so daß im Gerät 1 die Anzeige kommt. Im eingestellten Takt wird in Gerät 1 eine Reihenanzeige aufgebaut, die sich solange wiederholt, bis das Gerät 2 abgeschaltet wird. Durch die Reihenprüfung kann eine Vertauschung, sowie übergangswiderstände, sofort erkannt und teseitigt werden.This test process is as follows: Device 2 generates a pulse at a pitch of 1-10 seconds (can be switched on), which sets a bistable multivibrator. This level If an H signal is sent to the connected wire, the display is displayed in device 1. In the set Cycle a row display is built up in device 1, which is repeated until device 2 is switched off. A mix-up, as well as contact resistances, can be recognized and eliminated immediately through the series test.
