Abstract
The utility model relates to a welding type thermal resistor, which comprises a chip, a pair of leads and an epoxy resin encapsulating layer, wherein the chip is connected between two lead clamping segments and is welded with the two leads; the outer parts of the chip and the lead clamping segments are integrally encapsulated by the epoxy resin encapsulating layer; and the extending parts of the leads, not encapsulated by the epoxy resin encapsulating layer, are provided with a pair of mutually-corresponding outer convex grooves. Due to the outer convex grooves, when a pair of leads of the extending part of the welding type thermal resistor is welded onto an external circuit, the operation is easier, the leads not welded are not easily damaged, and therefore the welding cost is saved.
Description
Technical field
The utility model relates to a kind of thermistor, particularly a kind of solder type thermistor that has lead-in wire.
Background technology
In daily commercial production and life, thermistor is widely used in the measuring temp and the control in household electrical appliances communication and instrument product field.The solder type thermistor comprises chip, pair of lead wires and encapsulated layer; In daily application; Often the lead-in wire of entrapped extension is not welded to be connected on the external circuitry; In the process of welding, often occur damaging lead-in wire or the low situation of welding efficiency, thereby had a strong impact on the cost of welding.
The utility model content
The utility model provides a kind of processing ease, not the solder type thermistor of fragile lead-in wire to the deficiency of prior art.
The utility model is realized through following technical scheme:
A kind of solder type thermistor; Comprise chip, pair of lead wires and epoxy resin enclosed layer; It is characterized in that: said chip be connected between the pair of lead wires folder section and with two wire bonds; Chip and the outer integral body of lead-in wire clamping connection section are sealed by epoxy resin enclosed layer, and the extension of not sealed by epoxy resin enclosed layer of said pair of lead wires has the outer tongue of a pair of mutual correspondence.
Further, said chip is vertically indulged between the clipper joint that inserts in two lead-in wires.
The beneficial effect of the utility model is: when the pair of lead wires of this solder type thermistor extension of outer bound pair is welded on the external circuitry; Free space during welding that nationality is emitted by the outer tongue in the lead-in wire of the extension of not sealed by epoxy resin enclosed layer; Make the welding process operation easy; Not fragile lead-in wire, thus welding cost reduced.
Description of drawings
Fig. 1 is the sketch map of solder type thermistor.
Wherein, Reference numeral
1---chip
2---lead-in wire
3---epoxy resin enclosed layer
4---outer tongue
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
As can be seen from Figure 1; A kind of solder type thermistor; Comprise chip 1, pair of lead wires 2 and epoxy resin enclosed layer 3; Said chip 1 vertical indulging between the clipper joint that inserts in pair of lead wires 2 and with two lead-in wires 2 welded, and chip 1 and the outer integral body of the 2 clamping connection sections that go between are sealed by epoxy resin enclosed layer 3, and the extension of not sealed by epoxy resin enclosed layer 3 of said pair of lead wires 2 has the outer tongue 4 of a pair of mutual correspondence.
When the pair of lead wires 2 of this solder type thermistor extension of outer bound pair is welded on the external circuitry; Free space during welding that nationality is emitted by the outer tongue 4 in the lead-in wire 2 of the extension of not sealed by epoxy resin enclosed layer 3; Make the welding process operation easy; Not fragile lead-in wire 2, thus welding cost reduced.
Below the utility model is done a detailed description, but obvious, those skilled in the art can carry out various changes and improvement, and the scope of the utility model that does not deviate from appended claims and limited.
