Abstract
The utility model relates to a small glass-encapsulated type negative temperature thermosensitive resistor which is provided with two metal lead wires, a glass housing and a resistor chip. The resistor chip is vertically placed in the glass housing; silver electrodes are coated at the front ends of the two metal lead wires; the metal lead wires are connected with electrodes on the left and right surfaces of the resistor chip through the silver electrodes respectively; the front ends of the two metal lead wires and the resistor chip are encapsulated in the glass housing; and the two metal lead wires are extended out from one end of the glass housing. The thermosensitive resistor has a smaller volume and can be applied to small products; the operating temperature range of the thermosensitive resistor is wide, and the change rate of the resistance value in high-temperature and low-temperature working is smaller.
Description
Technical field
The utility model relates to glass packaging type negative temperature thermistor device, relates in particular to a kind of small size glass packaging type negative temperature thermistor device.
Background technology
Negative temperature coefficient thermistor is widely used in the temperature-compensating of the measuring temp of household appliances, communication class product and control, instrument and meter series products and to the measurement (as: wind speed, vacuum degree, temperature etc.) of environment.The conventional at present glass packaging type negative temperature coefficient thermistor of making adopts two-way wire type, have chip, lead-in wire and glass shell, lead-in wire contacts with the chip direct mechanical, lead-in wire is enclosed in the glass shell with the chip glass, lead-in wire stretches out from the two ends of glass shell are two-way, and the defective that this thermistor exists is: 1, the body dimension of thermistor is big, needs the space of installation bigger, general minimum needs the space of 5*8mm, can not be applied on the small sized product; 2, can not at high temperature work long hours, about 200 ℃ of general maximum operating temperatures, and also the rate of change of resistance is bigger, and rate of change was about 5% in general 1000 hours.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of small size glass packaging type negative temperature thermistor device is provided, the bulk volume of its thermistor is less, can be applicable on the small sized product, the applied operating temperature range of thermistor is wide, and its resistance varying-ratio is less during long-time high low-temperature working.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of small size glass packaging type negative temperature thermistor device, have two metal lead wires, glass shell and resistance chip, described resistance chip vertically is placed in the glass shell, described two metal lead wire front ends are coated with silver electrode, two metal lead wires are connected by the electrode of silver electrode with two sides, the resistance chip left and right sides respectively, two metal lead wire front ends and resistance chip are encapsulated in the glass shell, and two metal lead wires stretch out in the same way from an end of glass shell.
The beneficial effects of the utility model are: two metal lead wires of the present utility model stretch out in the same way from an end of glass shell, described small size is meant that the utility model is littler with respect to its bulk volume of thermistor of the two-way wire type same specification of prior art making, can be applicable on the small sized product, metal lead wire is connected with the resistance chip by silver electrode, make that the temperature range of its work is wideer, its resistance varying-ratio is less during long-time high low-temperature working.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Wherein: 1. metal lead wire, 2. glass shell, 3. resistance chip
Embodiment
