Abstract
The utility model belongs to the field of a protector, and especially relates to a current overload protector. The purpose of the utility model is to provide an overload protector provided with a temperature-sensitive element with high temperature-sensitive precision. The overload protector is provided with a static contact piece, a cover plate, a static contact, a moving contact, a moving contact piece, the temperature-sensitive element, a heating slice, a connection slice, a base, a first pin and a second pin. The temperature-sensitive element is a circular member, the base is provided with an installation groove for placing the temperature-sensitive element therein, and the temperature-sensitive element is freely arranged in the installation groove. The advantages are as follows: the temperature-sensitive element is freely installed in the installation groove and the temperature-sensitive element is not provided with any openings so that the temperature-sensitive precision and the life are both increased.
Description
Technical field
The utility model relates to a kind of protector, particularly a kind of current over-load protector.
Background technology
Most protectors are applied on the electric tool such as motor, ballast; day by day accurate small and exquisite along with these tool designs; it is more and more less that the structure of protector also designs; Mini-sized protector, because volume is little, is not only conveniently installed to narrow and small position and also can be installed on required product by mosaic mode.The key structure of protector is the installation of temperature-sensing element, and quality is installed for it and configuration design is related to protector disconnection precision and life-span.
Utility model content
The purpose of this utility model is to provide a kind of temperature-sensing element temperature-sensitive precision higher overload protective device.
The technical scheme that realizes the utility model object is:
A kind of overload protective device; there is static contact, cover plate, fixed contact, moving contact, movable contact spring, temperature-sensing element, fever tablet, brace, base and first and second pin; above-mentioned temperature-sensing element is circular piece; above-mentioned base is provided with the mounting groove of laying temperature-sensing element, and temperature-sensing element is freely placed in mounting groove.
Above-mentioned static contact, first and second pin are directly inserted into base and fix by riveted joint.
The 5th, six pilot holes that above-mentioned base is provided with first and second pilot hole coordinating with the pin of static contact, third and fourth pilot hole coordinating with the pin of first and second pin and coordinates with the assembling post on cover plate.
Benefit of the present utility model is that this novel temperature-sensing element is freely arranged in the mounting groove of base, and temperature-sensing element is without any perforate, and temperature-sensitive precision and life-span are all improved.
Accompanying drawing explanation
Fig. 1 is generalized section of the present utility model.
Fig. 2 is protector rearview.
Fig. 3 is that protector goes schematic internal view after cover plate.
Fig. 4 is blast structural representation.
Embodiment
See Fig. 1, Fig. 2, Fig. 3 and Fig. 4, this novel overload protective device comprises static contact 1, cover plate 2, fixed contact 3, moving contact 4, movable contact spring 5, temperature-sensing element 6, fever tablet 7, brace 8, the second pin 9, base 10, the first pin 11.Above-mentioned moving contact 4 is arranged at one end of movable contact spring 5, and movable contact spring 5 one sides and brace 8 are welded and fixed.Above-mentioned fixed contact 3 is located on static contact 1, and on two pin inserted bases 10 of static contact 1 in first and second pilot hole 101,102, and riveted joint is fixing, and the static contact other end can be connected with outside inserted sheet.Above-mentioned the first pin 11 is welded and fixed with fever tablet 7, and fever tablet 7 other ends and the second pin 9 are welded and fixed, and the pin of first and second pin 11,9 is respectively on inserted base 10 in third and fourth pilot hole 103,104, and riveted joint is fixed.The first pin 11 can be connected with outside inserted sheet, and brace 8 and the second pin 9 are by being welded and fixed.Above-mentioned temperature-sensing element 6 is arranged between movable contact spring and fever tablet, is shelved on the mounting groove in base, and temperature-sensing element can be freely movable.On above-mentioned cover plate 2, there are two assembling posts, match with the 5th, six pilot holes 105,106 on base 10, and fix by the mode of hot melt.
In the time of this New Protector place in circuit; the large current heating of protector fever tablet 7; temperature-sensing element 6 is under thermal effect effect; sudden change upset promotes movable contact spring 5 and makes its one end perk with moving contact 4, and moving contact 5 is separated with fixed contact 3, thereby cuts off circuit loop; after on temperature-sensing element, heat leaves; temperature-sensing element 6 recovery that can automatically reset, thus circuit loops are connected in two contacts contacts, are more than current protector operation principle.
It is movable that this Novel temperature sensing element is free in floor installation groove, and on temperature-sensing element, without any perforate, protector disconnects precision and the life-span all improves a lot, and base adopts high-temperature plastic wood material, and product resistance to elevated temperatures improves a lot.
Obviously, above-mentioned embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to the utility model execution mode.For those of ordinary skill in the field, can also be easy on the basis of the above description make other pro forma variation or substitute, and these changes or alternative also by within being included in the definite protection range of the utility model.
