Abstract
The utility model discloses an NTC (Negative Temperature Coefficient) temperature sensor adopting a double-row wire, which consists of an NTC chip and a PVC (polyvinyl chloride) lead welded on the chip, and the chip and the welding spot are encapsulated by epoxy resin. The NTC temperature sensor is characterized in that the adopted PVC lead is the double-row wire, the wire ends of the double-row wire are reshaped and processed to be close to each other to form a plier-shaped structure, and the plier-shaped structure has certain clamping force, the NTC chip is clamped by the wire ends and can be directly dip soldered, and the production efficiency is greatly improved.
Description
Technical field:
The utility model relates to the NTC sensor, specifically, relates to the lead-in wire of NTC sensor.
Background technology:
The NTC themistor chip directly is welded on the PVC lead-in wire, at surface-coated epoxy resin, can become a NTC temperature sensor, be widely used in fields such as automotive electronics, communication, computer power, Notebook Battery, household electrical appliance and play temperature control and thermometric effect, therefore the market demand is very big, and the raising of production efficiency is very important to reducing production costs.
Tradition NTC sensor generally adopt two independently lead-in wire be fixed on side by side on the dull and stereotyped frock, chip is positioned between two lead-in wires, owing to do not have holding force between two lead-in wires, the end of a thread of two lead-in wires is drawn close each other, ability clamping chip immerses the welding of tin stove with lead ends; Perhaps by chip of artificial each welding separately.These two kinds of method efficient are extremely low, and cost of labor is very high.
Summary of the invention:
For improving the welding efficiency of NTC sensor lead, lead-in wire of the present utility model is used double line instead, and (promptly two line parallels are connected as a single entity side by side, but have two heart yearns insulated from each other), and double line carried out following processing: behind will go between stripping head, the wicking, with unit clamp to soaking the end of a thread shaping of tin, make that two the end of a thread are drawn close each other, bending, have certain holding force, chip pushes the end of a thread gap and is promptly clamped.The immersed solder together of whole row's product, efficient can improve several times.
Description of drawings:
Fig. 1. double line and independent lead-in wire synoptic diagram
Fig. 2. the end of a thread is through the double line of shaping
Fig. 3. be fixed on the parallelly-arranged double-row line on the anchor clamps of plane
Fig. 4. clip the parallelly-arranged double-row line of chip
Fig. 5. the enlarged drawing of pincerlike the end of a thread (4) clamping chip (6)
Embodiment:
As shown in Figure 1: adopt double line (1) to replace original two independent lead-in wires (2), and, form two-wire head (3) with certain degree of hardness with double line stripping head, wicking.
Adopt unit clamp that the two-wire head (3) that strips out is carried out shaping, make two the end of a thread draw close each other, (making it have certain holding force), online cephalic par is outwardly-bent again separately, and (so that chip smoothly pushes) forms pincerlike two-wire head (4) as shown in Figure 2.
Many after the shaping double lines are fixed on the anchor clamps of plane on (5), as shown in Figure 3 side by side.Chip (6) is pushed in the middle of pincerlike the end of a thread (4) of each double line, and by pincerlike the end of a thread clamping, as shown in Figure 4.Fig. 5 is the enlarged drawing of pincerlike the end of a thread (4) clamping chip (6).
Tin liquor (wicking) 1-2 that a plurality of the end of a thread that will clip chip (6) immerse fusing side by side proposed after second, and each bar lead-in wire has just been got well with chips welding.Like this, the welding efficiency of NTC sensor lead has just improved several times.
Claims (2)
1. NTC temperature sensor that adopts double line, constituted by NTC chip, the PVC lead-in wire institute that is welded on the chip, chip and solder joint thereof are sealed by epoxy resin, it is characterized in that: the PVC lead-in wire that is adopted is double line, and connect an end of chip at double line,, make that the end of a thread is drawn close each other, bending in advance to two the end of a thread shapings processing, form pincerlike structure, have certain holding force.
2. a kind of NTC temperature sensor that adopts double line according to claim 1, it is characterized in that: when the NTC chip was connected with double line, chip directly inserted the end of a thread that double line is drawn close each other, and by the end of a thread clamping.
