An optical temperature sensor head having an optical fibre and a sensor material, which is optically connected to a free end of the optical fibre. The free end of the optical fibre has an overmould made of a plastics material, which engages over a free end of the optical fibre and forms a protective body. A transparent window is arranged in the protective body. The window permits an optical connection with the free end of the optical fibre. Luminescence radiation from a sensor material can enter the optical fibre. The protective body has the effect that the temperature sensor head is mechanically stable and is insensitive to environmental influences. A temperature sensor device having such a temperature sensor head. An electric machine having a winding with a winding wire, which is connected to a proposed temperature sensor head.

Optical temperature sensor head, temperature sensor device and electric machine having a temperature sensor head

An arrangement () for covering connecting points of electrical lines (-) in a moisture tight manner is indicated. The electrical conductors (-) of at least one first electrical line () are connected to the electrical conductors (-) with at least two further electrical lines (-). The connecting point is surrounded by a prefabricated housing () consisting of a mechanically stable synthetic material. The interior of the housing () is completely enclosed by a sealing material produced by injection molding which extends to both sides of the housing () up to the lines protruding beyond the housing (-).

Arrangement for sealing the connection point of electrical lines

A coupling part for an electrical line has an insulator having a receiving side and an oppositely lying plug-in side and throughholes, in which are arranged insulated electrical contact elements relative to each other, to which, in the mounted position, the electrical conductors of the line are connected on the receiving side of the insulator. A surrounding prefabricated housing is mounted over the connecting point of the conductors and contact elements, so that on the one side it stretches up to and over the insulator and on the other side up to and over the line.

Coupling part for an electrical conductor

A protective element for manufacturing circuit boards is provided, where conductors are fastened to the contacts of the conductors. The protective element includes recesses which are configured for arranging a conductor each, and the protective element can be arranged adjacent a support. The recesses of the protective element are arranged in a first position in alignment with the recesses of the support and in a second position at an angle relative to the recesses of the support. Preferably, the protective element has at least one hinge section which is configured for interacting with a complimentary hinge section of a support which can be mounted against the protective element, where pivoting of the protective element against the support about the pivoting axis of the interacting hinge sections moves the protective element on the support from the first position into the second position.
