Abstract
The utility model discloses a glass-sealed negative temperature coefficient thermistor with a single-ended outgoing line, and belongs to the technical field of a thermistor. The utility model mainly consists of a negative temperature coefficient thermistor core (1) and a pair of electrode layers (2) which are laid at the two sides of the negative temperature coefficient thermistor core (1), and an outgoing line which is fixed at a pair of electrode layers (2); an encapsulated layer (4) is added outside the negative temperature coefficient thermistor core (1). The utility model is convenient to be assembled and can be used in wide temperature zones.
Description
Technical field
The utility model belongs to the thermistor technology field, is specifically related to a kind of single-ended lead-out wire glass envelope type negative temperature coefficient thermistor.
Background technology
At present, the negative temperature coefficient thermistor that is used for the thermometric field, its primary structure has following two kinds: a kind of is single-ended epoxy packages type negative temperature coefficient thermistor, it is by the negative temperature coefficient heat-sensitive chip, be welded in two side by side the lead-in wire between, form with epoxy resin enclosed again, this welding manner has advantages such as simple in structure, easy for installation, but its use warm area is narrow, below 100 ℃.Another kind of draw glass envelope type negative temperature coefficient thermistor for axial two ends, it is by the negative temperature coefficient heat-sensitive chip, two lead-out wires and glass bulb composition, and lead-out wire is plugged in the glass bulb, and the negative temperature coefficient heat-sensitive chip is embedded between two line outlets.It has the advantage (maximum operation (service) temperature can reach 300 ℃) of using wide temperature region, but since two lead-out wires at the two ends of chip, be not easy to install and use.
Summary of the invention
In order to solve the problems of the technologies described above, the purpose of this utility model is that a kind of single-ended lead-out wire glass envelope type negative temperature coefficient thermistor will be provided, easy for installation and use wide temperature region.
The technical solution adopted in the utility model is as follows: it is made up of negative temperature coefficient heat-sensitive core and the be laid in pair of electrode layers of negative temperature coefficient heat-sensitive chip both sides and the lead-out wire that is installed on the pair of electrode layers, and described negative temperature coefficient heat-sensitive core outside has additional encapsulated layer.
Described negative temperature coefficient heat-sensitive chip adopts the oxide powder of manganese, cobalt, nickel, iron to be made.
The material of described electrode layer is silver or silver-colored palladium.
Described lead-out wire adopts the metallic conduction material to form.
The beneficial effects of the utility model are: when using this thermistor, only need its lead-out wire is got final product with the jack or the corresponding welding of flat cable of wiring board respectively, install very convenient; And, both can be used for the normal temperature place owing to adopt glass packaging, and also can be used for high temperature place (as microwave oven, water heater etc.), use wide temperature region.
Description of drawings
Fig. 1 is a sectional structure schematic diagram of the present utility model.
1. negative temperature coefficient heat-sensitive cores among the figure, 2. electrode layer, 3. lead-out wire, 4. encapsulated layer.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Be illustrated in figure 1 as a preferred embodiment of the present utility model.As shown in the figure, the utility model mainly is made up of negative temperature coefficient heat-sensitive core 1 and the be laid in pair of electrode layers 2 of negative temperature coefficient heat-sensitive chip 1 both sides and the lead-out wire 3 that is installed on the pair of electrode layers 2, and negative temperature coefficient heat-sensitive core 1 outside has additional encapsulated layer 4.
Negative temperature coefficient heat-sensitive chip 1 adopts the oxide powder of manganese, cobalt, nickel, iron to be made.The material of electrode layer 2 is a silver, and lead-out wire 3 adopts the metallic conduction material.The negative temperature coefficient heat-sensitive chip 1 that is welded with lead-out wire 3 is put encapsulated layer 4, and high temperature sintering makes encapsulated layer 4 fusions coat negative temperature coefficient heat-sensitive chip 1 then.Encapsulated layer 2 is resistant to elevated temperatures insulating material glass.
When using the utility model, only need lead-out wire 3 with negative temperature coefficient thermistor, get final product with the jack or the corresponding welding of flat cable of wiring board respectively, install very convenient.And, both can be used for the normal temperature place owing to adopt glass packaging, and also can be used for high temperature place (as microwave oven, water heater etc.), have advantages such as easy for installation, use wide temperature region.
