Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrical connector, for example for a proportional flow counter, comprising a plug assembly (B), a counterpiece (for example socket assembly A) and contacts required for power supply.

In radiation measurement technology in atomic science, particularly in the field of radiation protection (health) monitoring, proportional flow counters of various embodiments are used in many ways as detectors and measurement sensors. In order to operate these detectors, in addition to a power supply, gas lines are required for the flow of the counting gas. Some assemblies require, for example, thin hose pipes.

Traditionally, this counting gas supply has been carried out by a separate gas conduit, separate from the electrical cable connection between the detector and the measurement electronics. However, this would at least not cause the tube to sew or otherwise block the instrument head.

The object of the invention is to provide: 1. a novel connector connection which provides a good line of sight and saves space; The aim is to solve the problem of electricity supply and gas supply technically and completely.

The inventive connector developed for the above purpose is provided with two additional gas lines in the assemblies A and B which form two gas connections in the connector for supplying and discharging gas. It is characterized by

By incorporating the gas supply section into the electrical connector,
A particularly detailed embodiment of the measuring sonde is realized. Such an embodiment can be used, for example, to monitor contamination in narrow conduits. By the way, we have manufactured a special sonde that has an inner diameter of 16 mm and is suitable for measuring radioactivity in a 1 m long pipe.

According to an embodiment of the present invention of a proportional flow counter reservoir, one of the gas lines in the socket assembly extends substantially to the end of the sonde.

The electrical connector sump cable of the invention can be provided with two gas tubes integrated into the cable sheath.

The attached drawings show a connector assembly 2 and six low voltage contacts 6 according to the invention. This receiver i4 further accommodates two gas lines 5. One of the two gas pipes 5, which is used for gas supply, can be extended, for example, to the sonde end C (possibly through the tube).

Plug assembly IJB has correspondingly connectable contacts 2, 3 and gas line 5. These gas pipes 5
are each integrated with a corresponding conduit in the opposing piece.

Preamplifiers, which may be installed in the sensor, are preferably bridged by gas lines.

The socket assembly can also be used as a thermal cable connection assembly.

Plug assembly B can be used, for example, not only for electrical lines, but also for
It is provided at the end of the cable which also has a gas pipe which is located inside the cable sheath or is integrally connected to the cable sheath.

Although the respective casings of the reservoirs of assemblies IJA and B are not shown, these casings can be designed arbitrarily.

Thermal The illustrated electrical connector can be used not only in proportional flow counters, but also in all other devices where gas supply and discharge are required in addition to electrical connections.
