Description

Connection of component to cable

Technical field

The technical solution relates to a field of technology in which various sensors terminated with a sensor cable are used, in particular the field of measuring, communication and automation technology.

BACKGROUND OF THE INVENTION

In the art, there is often a need to firmly attach a functional feature to a cable that conducts electrical current from / to the main body of the functional device.

According to the state of the art, the structural elements are firmly connected to the conductive cables by their contact conductors such that the contact conductors of the element are longitudinally applied to the individual conductors in the stripped cable parallel to each other and firmly attached (soldering, spotting, wrapping or crimping to the conductors) . Thus, the current connection is represented by two wires placed side by side and fixed in some way to each other. The individual joints must then be separated from each other and from the outside by a non-conductive material, as there is a risk of a short connection between the joints or between the joint and the external conductive environment, eg by the sensor sheath and the cable.

For the contact connection of the element to the prior art cable, it is necessary to:

1. Remove the cable sheath where necessary to detect insulated wires.

2. Remove the insulation from the individual wires in the required length.

3. Attach element wires by soldering, spotting, wrapping, or crimping to cable wires.

4. Electrically insulate the wires from each other.

5. Electrically insulate the conductors from the protective metal sheath.

The essence of the technical solution

The present technical solution represents a simpler connection of the structural element (its wires) with the cable (its wires). This connection consists in conductive contact of the element conductor placed (inserted) between the cable wires of the cable conductor in the direction of the individual cable conductors, fixed as necessary in the cable conductor termination area by soldering, conductive sealant, conductive paste or conductive adhesive.

The connection is characterized in that it does not require the removal of the appropriate part of the cable insulation necessary to connect or remove the appropriate length of the cable conductor or the attachment of the conductors of the element (eg sensor) to the cable conductors by mechanical means (soldering, wrapping, crimping, etc.). cable conductor wires and elasticity of cable conductor insulation and overall mechanically fixed and positioned by the mechanical strength of the cable conductors in conjunction with the cable sheath to the extent that it makes it possible to create a compact electromechanically sufficiently strong connection suitable for electrotechnical applications between the conductors and the protective sheath, it is possible to further secure the contact of the joints by subsequent soldering, conductive sealing or conductive bonding.

The developed new technical solution makes it possible to omit the steps according to paragraphs 1, 2, 4 and 5 mentioned above in the section "Prior Art" in comparison with the state of the art in connection construction. This results in less labor in the construction of the joint and hence lower costs.

In addition, such a connection assumes the mechanical strength of the cable, and so it is not necessary to insulate the conductors between themselves as they are insulated by the existing insulation of the cable conductors and are also at a sufficient distance from the edge of the cable sheath as well as the protective metal sheath. In this way, compared to the prior art, considerable savings are achieved on the material required for the subsequent insulation of the connections and conductors both between themselves and the outside.

Overview of the figure in the drawing

One drawing is enclosed. Giant. 1 shows the technical solution applied for.

Examples

The connection, according to FIG. 1, consists of an element I, for example a temperature sensor, and a cable, in the state in which its length has been cut, without further stripping the conductors of the cable 3 into which the conductors of the element 2 are inserted. In this way, the temperature sensor 1 is electrically contacted and fixed mechanically to the cable conductors by clamping the elasticity of the cable conductor insulation 4 and the cable sheath 5. possible subsequent additional soldering or bonding or bonding with conductive adhesive, but not necessary. Finally, the sensor can be aligned axially with the cable axis and the sensor connected in this way with the cable part can be inserted into the protective sheath.

Industrial applicability

Industrial applicability is mainly in the field of production of various sensors, terminated with cable and sensor for measuring and automation as well as communication technology.
