Description
Technical field
The present invention relates to the safety device on a kind of gas-cooker utensil, the electrical connection that it comprises electromagnetic valve, flame detector thermocouple and is used for thermocouple wire is connected to this valve.
Background technology
Be equipped with on the kitchen range stove circle (hob) of safety valve, be called " main lead-in wire (1ine) " by two and the electric wire of " ground wire (ground) " provides the excitation electromagnet by the flame detector thermocouple, this two wire is provided with waits to be inserted into promptly slotting accordingly (fast-on) splicing ear in the corresponding joint pin on the valve.This safety valve is a cylindricality, and be assemblied in kitchen range with in the metal shell in the combustion gas regulating cock of metal stop nut tight jam-pack.Thermocouple " ground wire " terminal is connected with this stop nut." main lead-in wire " terminal is connected with cylindricality joint pin on the valve, and this joint pin extends vertically and reaches outside " ground wire " stop nut.The valve binding post has the annular groove that is used for fixing the thermocouple line terminal.From
EP-0691510-AIn known such electric commutator that is used for safety valve.
Because the free space in the kitchen range stove circle below safety valve is limited, therefore must carry out thermocouple wire is connected to attended operation on the valve from cross side, and must radially terminal is inserted along relative valve axis.
FR-2696531-A3Disclose a kind of flame detector thermocouple with two wires (" main lead-in wire ", " ground wire "), this two wire is connected on the safety valve electromagnet from the side, thereby locatees with respect to the radial axis of valve.
The shortcoming that this known electrical connection has is, respectively two thermocouple wires are connected on the valve by twice manual operation, in addition, for fixing " ground wire " terminal and to make it electrically contact impedance less, " ground wire " terminal has increased in the lip-deep electric welding operation of regulating cock.
Summary of the invention
The combination that the objective of the invention is to a kind of flame detector thermocouple and electromagnetic valve is to be applicable to gas-cooker stove circle, two terminals of thermocouple wire are arranged in the connector body of insulation, are used in the mode of edge with respect to the radial directed of described valve axis described two terminals being inserted in the safety valve joint pin.
The objective of the invention is to, it is that spigot is connected on the corresponding valve joint pin that two thermocouple wires should make the assembling user to carry out two with the quick operation of single with being electrically connected of safety valve, promptly be connected on axially extended " main lead-in wire " post and " ground wire " post (for the valve chest stop nut), this stop nut outer exposed goes out to be used for the contact surface of the general planar of ground wire terminal.Two terminals all are included in the insulator connector of hollow, thereby provide low-resistance contact to be connected between the stop nut outside ground wire terminal and valve, and make electric wire in case insert just be fixedly attached on the valve.
