Technical scheme: a kind of reverse type terminal thermostat, comprises housing, on described housing, left and right is provided with two terminals, and described terminal edge upwards extends to form inserted sheet, and terminal is provided with fixing hole, and terminal is connected with housing by fixing hole by screw; Lower cover is arranged in housing, embossing lid be sleeved on down cover and with housing clamping, thermal sensitive piece is arranged between lower cover and embossing lid, left joint pin, right joint pin are arranged in housing, and lower cover connects respectively, described right joint pin is fixed with a connecting piece, spring leaf and this brace are fixed, spring leaf is provided with wire, described wire is connected with terminal, left joint pin is fixed a connection contact, and described connection contact and spring leaf are respectively equipped with corresponding contact, push rod is arranged in lower cover, and contacts with spring leaf.
Above-mentioned reverse type terminal thermostat, described inserted sheet is the right-angled trapezium inserted sheet of hypotenuse to casing center, and described two inserted sheets are along casing center setting in a center of symmetry.
Above-mentioned reverse type terminal thermostat, described spring leaf is provided with the contact coordinated with push rod.
Above-mentioned reverse type terminal thermostat, the contact on described connection contact and spring leaf contacts with each other when initial condition.
Above-mentioned reverse type terminal thermostat, described thermal sensitive piece is bimetallic strip.
Improve as one of the present utility model, above-mentioned reverse type terminal thermostat, described housing is provided with movable installing ring, and described movable installing ring and housing are nested fixing.
Improve as one of the present utility model, above-mentioned reverse type terminal thermostat, described housing overcoat has capping.
Technique scheme can be found out, the utility model has following beneficial effect: reverse type terminal thermostat described in the utility model, and structure is simple, and production cost is low, connects fastening, contacts effective, stable practical.
Accompanying drawing explanation
Fig. 1 is the vertical view structural representation of reverse type terminal thermostat described in the utility model;
Fig. 2 is the structural representation of reverse type terminal thermostat described in the utility model;
Fig. 3 is the structural representation of the reverse type terminal thermostat of a kind of improvement described in the utility model;
Fig. 4 is the structural representation of the reverse type terminal thermostat that another kind described in the utility model improves.
In figure: 1 housing, 2 thermal sensitive pieces, 3 wires, 4 left joint pins, 5 right joint pins, 6 connection contacts, 7 braces, 8 spring leafs, 9 embossing lids, 10 lower covers, 11 push rods, 12 terminals, 12a inserted sheet, 12b fixing hole, 13 movable installing rings, 14 cappings.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
Reverse type terminal thermostat as shown in Figure 1-2, this thermostat comprises housing 1, comprise housing 1, on described housing 1, left and right is provided with two terminals 12, terminal 12 edge upwards extends to form inserted sheet 12a, inserted sheet 12a is the right-angled trapezium inserted sheet 12a of hypotenuse to housing 1 center, and two inserted sheet 12a are along the setting in a center of symmetry of housing 1 center.Terminal 12 is provided with fixing hole 12b, and terminal 12 is connected with housing 1 by fixing hole 12b by screw.Lower cover 10 is arranged in housing 1, embossing lid 9 to be sleeved on lower cover 10 and with housing 1 clamping, thermal sensitive piece 2 is arranged between lower cover 10 and embossing lid 9, left joint pin 4, right joint pin 5 is arranged in housing 1, and lower cover 10 connects respectively, described right joint pin 5 is fixed with a connecting piece 7, spring leaf 8 is fixed with this brace 7, spring leaf 8 is provided with wire 3, wire 3 is connected with terminal 12 and wire 3 and housing 1 are fixed by scolding tin and be connected with electric device, left joint pin 4 is fixed a connection contact 6, described connection contact 6 and spring leaf 8 are respectively equipped with corresponding contact, push rod 11 is arranged in lower cover 10, and contact with spring leaf 8.Described spring leaf 8 is provided with the contact coordinated with push rod 11.
As shown in Figure 3, described housing 1 is provided with movable installing ring 13, and described movable installing ring 13 is nested fixing with housing 1.Movable installing ring 13 left and right sides is respectively equipped with fixing hole, and movable installing ring 13 can rotate to suitable position at horizontal plane, and screw is tightened fixing by fixing hole and testee.
As shown in Figure 4, described housing 1 overcoat has capping 14, is tightened to one.
Under operating state, the contact on described connection contact 6 and spring leaf 8 contacts with each other when initial condition.When the temperature increases, thermal sensitive piece 2 temperature distortion, pushes up on push rod 11, promotes spring leaf 8 up, thus makes contact separation, forms off state.When the temperature decreases, thermal sensitive piece 2 reinstatement, push rod 11 horizontal reset under the promotion of spring leaf 8, connection contact 6 contacts again with spring leaf 8 contact, forms conducting state.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
