Abstract
An indicating instrument has contact pins (6, 7, 8) which project into an encapsulation chamber (9). Within this encapsulation chamber (9), the contact pins (6, 7 8) are connected by welding to individual cores (10, 11, 12) of a connecting cable (13). The weld points are then covered by encapsulation compound in the encapsulation chamber (9).
Claims9
An indicating instrument which is intended in particular for a vehicle and has a housing with a connection having contact pins for a connecting cable comprising a number of individual cores, wherein the contact pins (6, 7, 8) are connected within an encapsulation chamber (9) by welding to the individual cores (10, 11, 12), and the weld points are covered by encapsulation compound in the encapsulation chamber (9).
The indicating instrument as claimed in at least one of the preceding claims, wherein the encapsulation chamber is provided on the rear face of the housing (1) of the indicating instrument, and is in the form of a box whose cross section is smaller than the cross section of the indicating instrument and which is open toward the rear face of the housing (1).
A method for connecting a printed circuit board of an indicating instrument, in particular in a vehicle, to a connecting cable having individual cores, in which the individual cores are each connected to a contact pin of the indicating instrument, wherein the contact pins are first soldered to the printed circuit board and are passed through the housing of the indicating instrument into an encapsulation chamber which is formed on the outside of the housing, wherein the individual cores of the connecting cable are then each connected by welding to a contact pin, and wherein an encapsulation compound is then introduced into the encapsulation chamber.
