Abstract
An electrical mains plug having a body formed of an electrically insulating material is described. Two contact pins are arranged parallel to one another and which project out of the body at a first side thereof, and inside the body are connected or can be connected in each case to an electrical conductor which leads out or can be led out of the body at a second side thereof. The thermal bimetallic element is provided as a temperature sensor, said thermal bimetallic element being a constituent part of the thermal bimetallic switch which is associated with at least one of two contact pins. An electrical connection cable suitable therefor and an electrical device connected thereto are also described.
Claims22
An electrical mains plug having a body formed from an electrically insulating material,
- two contact pins being arranged parallel to each other, each of which projects out of the body at a first side thereof,
- a sensor provided in association with said plug,
- said sensor being a temperature sensor having at least one thermal bimetallic switch, said at least one thermal bimetallic switch having a thermal bimetallic element,
- said sensor being associated with at least one of said two contact pins,
- further comprising a separate electrically insulating cover provided in said body,
- wherein said cover forms a mount for said at least one thermal bimetallic switch, and
- wherein said mount is open on its side opposite of said first side wherein said at least one thermal bimetallic switch is insertable from the opposite of said first side into said mount.
An electrical mains plug having a body formed from an electrically insulating material,
- two contact pins being arranged parallel to each other, each of which projects out of the body at a first side thereof,
- a sensor provided inside of said plug,
- said sensor being a temperature sensor having at least one thermal bimetallic switch, said at least one thermal bimetallic switch having a housing and a thermal bimetallic element in said housing,
- said sensor being thermally associated with at least one of said two contact pins,
- a separate electrically insulating cover being provided inside the body of the plug,
- and at least one mount arranged in said cover and constructed to hold said at least one thermal bimetallic switch,
- wherein said mount has an opening to insert said at least one thermal bimetallic switch into said mount, and
- wherein said opening and said at least one thermal bimetallic switch are over-moulded with a synthetic material of the body.
An electrical mains plug having a body formed from an electrically insulating material,
- two contact pins being arranged parallel to each other, each of which projects out of the body at a first side thereof,
- a sensor provided inside of said plug,
- said sensor being a temperature sensor having two thermal bimetallic switches, each of said two thermal bimetallic switches having a thermal bimetallic element,
- wherein one of said two thermal bimetallic switches is closer to a first of said two contact pins than to a second of said two contact pins, and that the other of said two thermal bimetallic switches is closer to the second of said two contact pins than to the first of said two contact pins,
- wherein said mains plug has an electrical connection conductor cable attached to said mains plug, electrical conductors and two extended signal lines extending inside said electrical connection conductor cable, each of said two contact pins being connected to one of said electrical conductors,
- and wherein said two thermal bimetallic switches are electrically connected in series and each of said two signal lines being connected to one of said two thermal bimetallic switches.
An electrical mains plug having a body formed from an electrically insulating material,
- two contact pins being arranged parallel to each other, each of which projects out of the body at a first side thereof,
- a sensor provided inside of said plug,
- said sensor being a temperature sensor having at least one thermal bimetallic switch,
- said at !east one thermal bimetallic switch having a metallic housing and a thermal bimetallic element in said housing,
- a separate electrically insulating cover being provided inside the body of the plug,
- wherein said cover forms a mount holding said at least one thermal bimetallic switch in a position next to at least one of said two contact pins in such a way that said housing does not come into contact with said two contact pins.
