DE102017111204A1 - Adapter for connectors - Google Patents

Abstract

The invention relates to an adapter (1) for plug connectors (2), comprising a housing (3) with a first plug side (3.1) and a second plug side (3.2), which has a means (4) for protection against lightning and overvoltage, wherein the means (4) within the housing (3) of the adapter (1) is arranged. This adapter (1) is necessary to protect components, electrical equipment or other electrical consumers from damage caused by lightning or overvoltage. Furthermore, the invention relates to a system with an adapter (1) according to the invention for protection against lightning and overvoltage.

Description

The invention relates to an adapter for connectors according to the preamble of independent claim 1.

Furthermore, the invention is based on a system for protection against lightning and overvoltage according to the preamble of independent claim 7.

Such adapters are needed, for example, to connect different connector types or to set up control points for the functionality of a component.

State of the art

The EP 2 009 747 A1 shows a connector system consisting of two housing parts, each comprising contact modules. Both housing parts are connected to each other via an adapter element. The adapter element simultaneously produces the electrical contact between the contact modules of the individual housing halves. The adapter element serves to connect the two housing halves and does not take on any further function.

The EP 0 576 171 B1 discloses a connection element for multi-pole electrical connectors. This connection element has a protective tube for protection against electromagnetic interference and a receptacle for a fixing element for electrical discharge, which engages around an end portion of the protective tube and which rotatably holds the fastener via clamping elements on the recording.

A disadvantage of the known variants for protection against lightning and overvoltage is that they are all directly fixedly mounted in a connector or a control cabinet. Thus, the protection against lightning and overvoltage within the cabinet is arranged and inflexible.

task

The object of the invention is to present an adapter for connectors, which reliably and flexibly protects a component and / or a system and / or a connector from overvoltages.

The object is solved by the subject matter of independent claim 1.

Advantageous embodiments of the invention are specified in the subclaims.

The invention relates to an adapter for connectors, comprising a housing having a first plug side and a second plug side, which has a means for protection against lightning and overvoltage, wherein the means is disposed within the housing of the adapter.

The adapter is designed like a connector. It has a housing and has a first plug side and a second plug side. The first plug-in side and the second plug-in side are arranged opposite one another. The adapter is suitable for connection to a plug connector and / or a component and / or a system through the first plug side and also the second plug side.

Components, systems or even electrical connections must be protected against overvoltages occurring, for example in the event of lightning or overcharging, as these will otherwise be destroyed. For this reason, the adapter according to the invention has a means of protection against lightning and overvoltage. This means is necessary so that the component is not damaged in the event of overvoltage. The means is arranged for optimum protection within the housing of the adapter. There, the agent itself is protected against environmental influences and is still flexible and suitable for use due to the installation in the adapter. Furthermore, results from the integration of the agent in the adapter and a space savings, because so the adapter can be mounted outside the cabinet or on a connector or on the component or on the system. This also offers the advantage that the entire system or the entire component is protected, including the inside of the cabinet located elements.

In a preferred embodiment, the means is designed as an electrical circuit. The advantage with this type of embodiment is the short reaction time to an overvoltage or a lightning strike. An electrical circuit can intercept these directly instead of having to convert them into, for example, mechanical energy or kinetic energy.

Advantageously, the electrical circuit is disposed within the adapter between the first plug side and the second plug side. Here is the most space inside the adapter. Furthermore, the lines between the adapter and the first mating side, such as between the adapter and the second mating side in this arrangement are approximately identical, so that here too a time delay is prevented, thereby increasing the overvoltage protection.

In a particularly preferred embodiment, the electrical circuit has a Gas arrester, at least two resistors and at least two diodes. These electrical components combined in a circuit, secure a connected to the adapter component or the like. The circuit allows effective protection against lightning and other forms of overvoltages.

In an advantageous embodiment, the gas discharge is a gas bladder with a gas discharge tube. The advantage of the gas discharge tube is the high breakdown voltage, which is between 65V and 10kV. Another advantage is the high current carrying capacity of the gas discharge tube, which is above 5kA.

Advantageously, the at least two diodes are each suppressor diodes or break-down diodes or zener diodes. The preferred variant is the suppressor diode, which has a short response time of about 1ps, withstands a continuous load of 1W and in the case of an overvoltage has an excellent quenching behavior without follow-up current.

The combination of gas discharge tube with gas discharge tube and suppressor diode enables a safe, stable and component-protecting form of protection against lightning and overvoltage.

The invention further relates to a system for protection, comprising a first component and a second component, wherein the first component and the second component can be connected to one another by means of at least one electrical conductor, wherein a means for protection between the first component and the second component Lightning and overvoltage is arranged, wherein the means is an adapter for connectors.

The adapter includes the above-mentioned properties and can be used in combination with the first component and the second component. Alternatively, the adapter can be used with only one of the two components, if this is connected directly to a voltage source.

The first component and the second component are, for example, an electrical system or a motor or an encoder or a rotary transformer or a connector or other consumer.

The adapter can be mounted in each case on the connection side of the first component or the second component. As a result, the adapter is outside the first or second component. This brings a large space savings and an increase in security with it.

The middle 4 To protect against lightning and overvoltage is inside the adapter 1 arranged. At the middle 4 it is an electrical circuit. The electrical circuit is at the first plug-in side 3.1 and to the second plug-in page 3.2 connected to ensure protection against lightning and overvoltage between these two sides.

The 2 is different from the 1 to the effect that the adapter 1 identifies an elongated cylinder as the base body. However, the first plug-in page 3.1 and the second plug-in page 3.2 not opposite each other, but arranged at right angles to each other at the two base surfaces of the cylinder. The middle 4 for protection is analog 1 inside the adapter 1 arranged.

The Circuit has a gas arrester 5 with a gas discharge tube, two resistors 6 and two suppressor diodes 7 on. Here is the gas arrester 5 connected to two phases and ground and in both phases is a resistor 6 installed. The resistors 6 are behind the gas collector 5 arranged. To the resistors 6 closes in each case a suppressor diode 7 which is in each case connected to one of the two first-mentioned phase on one side and on the other side to the remaining of the three phases. Over the remaining phase are the two suppressor diodes 7 also connected to ground again. This circuitry allows for effective protection against lightning and overvoltage.

The 4 shows in the middle an adapter 1 as he is in 1 is presented. To the adapter 1 becomes the first component to be a connector 2 connected and as a second component a rotary transformer. This is an exemplary use of the adapter according to the invention 1 ,
