Embodiment Construction

[0012] figure 1 Suspension 1 for terminals 2 , 3 of resistive element 4 is shown. Said terminals pass vertically through the body 5 and are attached relative to the upper surface 6 of this body 5 . Said terminals enter a heated portion of the resistive element 4 in the form of a rod element extending downwards from the terminals 2 , 3 . One or several of the rods 7, 8 of the heated part 4 are supported by hooks 9, 10 attached to the lower surface 11 of said body.

[0013] According to the invention, the suspension device 1 for each terminal 2 , 3 comprises a first attachment 12 attached to the upper surface 6 of the body 5 and a second attachment 13 , 14 attached to the terminals 2 , 3 , wherein a spring device 15 passes between the first attachment part 12 and the second attachment part 13, 14, the spring device 15 being arranged such that the second attachment part 13, 14 can be moved along relative to the first attachment part 12 Move vertically.

Abstract

A suspension arrangement for terminals for electrical resistive elements, which terminals pass vertically through a body and are attached relative to the upper surface of the body, which terminals pass over into the hot zone of the resistive element in the form of a shank element, which extends downwards from the terminals, where one or several of the shanks of the hot zone is or are supported by hooks attached to the lower surface of the body. The suspension arrangement for each one of the terminals includes a first attachment attached relative to the upper surface of the body and a second attachment attached relative to the terminal. A spring arrangement passes between the first and the second attachment, which spring arrangement is arranged such that the second attachment is mobile in the vertical direction relative to the first attachment.

Description

technical field [0001] The invention relates to a suspension for terminals of a resistive element. Background technique [0002] One type of resistive element is suspended vertically in a holder in the form of a body through which the terminals pass. This element usually has several rods whereby the upper curved area of ​​the element hangs in a hot zone attachment in the form of a hook attached to the cage. The terminals are also attached at the upper surface of the holder so as to bear the weight of the terminals in this way. This element cannot bear the weight of the terminal in its heated state. [0003] When heated, the heated portion, the heated portion attachment and the terminals all become longer. The extension of the terminals between the respective terminal holder and the upper level of the heat receiving part is greater than the extension of the heat receiving part attachment. This causes the weight of the terminal to be transferred to the first rod of the hea...
