Abstract
An one-piece resistance strain gauge of a terminal is characterized by comprising a strain gauge (1), soldering points (2), shielding lines (3), a pad (4) with a copper wire harness and a base plate (5), wherein the strain gauge (1) is disposed on an upper surface of the base plate (5); the soldering points (2) are disposed on a left side of a surface of the base plate (5); the left side of the base plate (5) is provided with the pad (4) with the copper wire harness; the strain gauge (1) is connected onto the soldering points (2) through fine leads; and the shielding lines (3) are connected with the soldering points (2) and the pad (4) with the copper wire harness respectively. The One-piece resistance strain gauge of the terminal is simple in structure, and since one end of the strain gauge is extended and fixes the pad with the copper wire harness, the soldering is convenient, and a welding success rate is improved.
Description
Technical field:
The utility model relates to a kind of resistance strain gage, is specifically related to a kind of terminal integral type resistance strain gage.
Background technology:
Foil gauge has the characteristics such as sensitivity coefficient is large, and mechanical hysteresis is little, and Standard resistance range is large, and transversal effect is little, is mainly used in measuring stress distribution, and as the power-electric transition element of various sensors.In the sensor that is formed by semiconductor gauge, form full-bridge circuit by four foil gauges, on flexible member, wherein two at when work Tensiles with four strain gauge adhesions, and two of another shrimps can make the sensitivity of electric bridge output the highest by compression like this.But because shielding line is thinner, solder technology is had relatively high expectations during the foil gauge welding, be welded into power not high.
The utility model content:
The purpose of this utility model is to provide a kind of terminal integral type resistance strain gage, and it is simple in structure, and foil gauge one end extends the convenient welding of pad of fixed copper wire harness, improves to be welded into power.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises foil gauge 1, pad 2, shielding line 3, the pad 4 with the copper cash bundle, base plate 5, foil gauge 1 is arranged on base plate 5 upper surfaces, pad 2 is located at left side, base plate 5 surface, base plate 5 left sides are provided with the pad 4 with the copper cash bundle, and foil gauge 1 is connected on pad 2 by thin wire, and shielding line 3 is connected with pad 4 with the copper cash bundle with pad 2 respectively.
Described pad 4 with the copper cash bundle replaces original elongated shielding line, improves the success ratio of welding when using.
The utlity model has following beneficial effect: it is simple in structure, and foil gauge one end extends the convenient welding of pad of fixed copper wire harness, improves to be welded into power.
Description of drawings:
Fig. 1 is the utility model structural representation;
Embodiment:
Referring to Fig. 1, this embodiment is by the following technical solutions: it comprises foil gauge 1, pad 2, shielding line 3, the pad 4 with the copper cash bundle, base plate 5, foil gauge 1 is arranged on base plate 5 upper surfaces, pad 2 is located at left side, base plate 5 surface, base plate 5 left sides are provided with the pad 4 with the copper cash bundle, and foil gauge 1 is connected on pad 2 by thin wire, and shielding line 3 is connected with pad 4 with the copper cash bundle with pad 2 respectively.
Described base plate 5 with once make moulding with the pad 4 of copper cash bundle and form.
Described pad 4 with the copper cash bundle replaces original elongated shielding line, the success ratio of welding during very high the use.
This embodiment has following beneficial effect: it is simple in structure, and foil gauge one end extends the convenient welding of pad of fixed copper wire harness, improves to be welded into power.
