  • Patent number: 9065188
    Abstract: The invention relates to an electrical connection having at least one plug contact element (10) and a connection wire (1) which is connected to the plug contact element (10), wherein the connection between the at least one plug contact element (10) and the connection wire (1) is established by means of at least one force-fitting connection (12, 13) which is in the form, in particular, of a crimped connection. According to the invention, provision is made for the force-fitting connection (13) to additionally be provided with a cohesive connection (15) or a soldered connection.

  • Publication number: 20030150634
    Abstract: An undetachable electrical and mechanical connection (4) between a contact element (7) has contacts (31) and a counter-contact element (8) has counter-contacts (27) with a flexible section (39) of the contact element (7) in at least the area of the contacts (31). Furthermore, the contact element (7) has at least one first and second layer (21, 22) which, in the area of the flexible section (39), define a gap (23) between them in which the counter-contact element (8) is located, the first and second layer (21, 22) each having at least one contact (31) on the inside surfaces (40) of the layers facing each other and the counter-contact part (8) having at least one counter-contact on each of its top and bottom (25, 26).

  • Patent number: 6364144
    Abstract: Short extensions (15) are formed on the housing (10) of a control device. These extensions (15) consist of the same material as the housing (10) and can therefore be produced in a simple and cost-effective manner in a single production process. The impact energy being created when the housing (10) is dropped on the ground can be compensated with the aid of these extensions (15). In special cases and as a function of the specifications, visually noticeable damage of the extensions (15) can be used as an indicator for possible damage to the electric components arranged in the housing (10).

  • Patent number: 5535098
    Abstract: The electrical device essentially consists of three main components, the circuit board (10), the housing bottom (11) and the housing cover (12). These three main components are joined to one another in the area of their outer edge. For this purpose, the housing bottom (11) and the housing cover (12) have mounting and, respectively, support sections (18, 25) which essentially extend parallel to the circuit board surface. In order to keep the unusable zones for mounting and joining circuit board and the housing parts small, the longitudinal extent of the joints is very much smaller than the total length of the corresponding circuit board edges (FIG. 3).
