Embodiment Construction

[0022] as from Figure 1A and 1B As can be seen in FIG. 1 , the plug device, here in the form of a cigarette lighter plug, denoted as a whole by 10 , has a housing 12 consisting of two complementary housing parts 12A and 12B. The housing is divided, for example, into a right-hand and a left-hand half in the plane of symmetry, and in the operating state the two housing parts are firmly screwed to each other. The plug device 10 has a front part which acts as a contact sleeve 11 which can be inserted into an electrical socket 20 at the Figure 1B In the contact sleeve 21 shown in the middle. The remaining housing parts, which are always placed outside the socket, act as handles for moving the plug device into the socket and for pulling it out, as well as for connecting the wires in the area of ​​the lead-in bushing 12C. Lead outward.

[0023] The contact sleeve 11 has two elongated housing wall cutouts 11A that lie opposite one another and extend in the plugging direction D. F...

Abstract

The invention relates to a plug device (10) in the form of a cigarette lighter plug, in particular for motor vehicles, for an electric connection to a low voltage outlet (20), comprising a housing part (12, 12A, 12B) located outside of the outlet (20), comprising a contact shell (11) that can be inserted into a contact sleeve (21) of the outlet (20), with at least one clamping means (13) arranged in a housing wall recess (11A) of the contact shell having at least one clamping jaw (13A) for fixing the plug device (10) after the insertion thereof into the outlet (20), with at least one spreading means (14) for outwardly spreading the at least one clamping jaw (13A) in relation to the contact shell (11) and with means for displacing the at least one spreading means (14). In order to be able to send relatively high currents to a user through a plug device in a safe manner and / or to improve the secure handling of the plug device, the invention proposes that the means for displacing the at least one spreading means (14) comprise a pushbutton arranged on a housing part (12, 12A, 12B) outside of the plug that is designed in such a way that the at least one spreading means (14) is displaced from a resting position (R) releasing the clamping jaws (13A) into a lockable spreading position (S) of the at least one clamping jaw (13A) and vice versa.

Description

technical field [0001] The invention relates to a plug arrangement in the form of a cigarette lighter plug, in particular for motor vehicles, which has the features of the preamble of claim 1 . Therefore, a cigarette lighter plug for a motor vehicle, that is to say a plug device generally used for electrical connection to a low-voltage socket, is provided with a housing part arranged outside the socket and with a contact sleeve that can be introduced into the socket. contact sleeve in the barrel. Furthermore, at least one clamping device with at least one clamping jaw arranged in the cutout of the contact sleeve is provided for securing the plug device after it has been introduced into the socket. At least one expansion means is used to expand the at least one clamping jaw outward relative to the contact sleeve, ie preferably transversely to the insertion direction of the plug device. When displacing the at least one expansion member, the direction component of the device ca...
