Abstract
The utility model relates to a novel combined Hall element and discloses a surface mount type Hall element which is fixedly welded on a small-sized circuit printed board. The electrical property of the novel combined Hall element is equal to the electrical property of an existing four-foot plug-in type encapsulating Hall element. The novel combined Hall circuit printed board with low price comprises a rectangular double-sided circuit printed board and the surface mount type Hall element, and is characterized in that four feet of the surface mount type Hall element are respectively and fixedly welded on four centrosymmetrical welding plates of the rectangular printed board. The novel combined Hall element is simple in structure, lower in price compared with the four-foot plug-in type encapsulating Hall element, and very convenient in production and welding.
Description
Technical field
The utility model relates to a kind of electronic building brick, is a kind of novel combination Hall element specifically.
Background technology
Current sensor is a kind of application electronic component very widely, and it is widely used in welding equipment, frequency converter, and various power supplys etc. are with in the automatic control field of electric current as controlling object.
Current sensor is based on the electronic component that hall principle is measured the various current signals that need detection.One of wherein most crucial element is exactly a Hall element, the Hall element encapsulation generally is divided into plug-in type, SMD, integrated encapsulation, the three respectively has pluses and minuses: 1, the plug-in type encapsulation is convenient installs, price is higher relatively, because plug-in type Hall element commonly used supply shortage is in short supply, use the higher plug-in unit Hall element of price instead in the recent period, cause the rising of production cost; 2, SMD Hall element is cheap, ample supply and prompt delivery, but need be furnished with special-purpose miniature circuit printed board, cost performance height on the whole; 3, the Hall element price height of integrated encapsulation, cost performance is not high.
Summary of the invention
It is on the high side that the utility model purpose provides the Hall element that solves the plug-in type encapsulation, a kind of scheme that mass production processes is complicated.
Technical solution of the present utility model is:
(1) SMD Hall element is weldingly fixed in the rectangle double-sided circuit printed board of SMD Hall coupling, general SMD Hall element is the encapsulation of four legs, and the circuit printed board that is complementary has corresponding four pads and eight rectangular pads of positive and negative;
(2) eight rectangular pads of rectangle double-sided circuit printed board positive and negative can be combined closely with current sensor main circuit board slot, and the pad on convenient and the main circuit board is corresponding one by one, and convenient the welding fixed.
Useful result of the present utility model is:
1, SMD Hall element of the present utility model is cheap, adds the price of miniature circuit printed board, and the plug-in type Hall element of using on the market is much lower, and has same good performance, therefore has very high cost performance.
2, eight rectangular pads of positive and negative can be combined closely with current sensor main circuit board slot, and convenience is corresponding one by one fixing with welding with the pad on the main circuit board, and the stability of current sensor is guaranteed.
