Embodiment Construction

[0032] figure 1 The illustrated contact device 1 comprises a housing 2 made of electrically insulating material. The housing 2 comprises four chambers 3 for accommodating a corresponding number of contact units 4 . Such a contact unit at figure 1 is shown exploded in order to clearly represent the individual components.

[0033] for plugging in a image 3 On the busbar 14 shown in , each contact unit 4 has a contact part 5 made of flat (steel) material with two elastic contact elements 6 . A bending spring 7 resting against the contact element 6 as described, for example, according to DE 3731625 A1 serves to provide a suitable contact force. The two contact elements 6 are bent at right angles and transition to a fixed leg section 8 on which two parallel elongated holes 10 are provided. As mentioned, two bolts 11 as fastening elements with corresponding washers 12 are used to fasten the contact part 5 .

[0034] Each chamber 3 includes a partition wall 13 as a support and...

Abstract

The invention relates to a contact device (1) for the detachable connection of a mobile appliance unit (30) to fixed conductor rails (14). Said device comprises a housing (2) consisting of insulating material, and contact units (4) which are housed in chambers (3) of the housing (2). Each contact unit (4) comprises at least one bent contact member (5), a connector part (16) which is likewise bent, and a guiding part (15) which is arranged between the two. An intermediate wall (13) is arranged in the chambers (3) of the housing (2), said wall comprising a window (22) for receiving the guiding part (15). An excessive thickness of the guiding part in relation to the intermediate wall (13), combined with the dimensions of the window (22), enables the contact units (4) to be displaced in the chambers (3) in relation to the housing (2). The contact units (4) can thus be oriented towards fixed conductor rails (14) without influencing the contact force.

Description

technical field [0001] The invention relates to a contact device for a detachable connection to a stationary busbar by pushing an adapter unit, comprising: [0002] at least one contact part made of flat material with contact elements and a fixed leg section bent from these contact elements, [0003] a connector for connecting the contact part to a conductor, [0004] a housing made of insulating material with a chamber for accommodating a contact unit consisting of said contact part and connecting piece, [0005] Wherein, the fixed leg section is connected with the connecting piece and is equipped with a through hole for the fixing piece to pass through. Background technique [0006] An important field of application for contact devices of this type is electrical switching devices, in particular low-voltage electrical switching devices. In this case, the adaptation unit comprises a combination of switching devices. These switching devices are required, for example, for ...
