Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a resistor mounted on a printed wiring board and having a voltage detection terminal at its terminal portion.

[0002]

[Prior Art]

 The terminals of a conventional resistor of this type are shown in FIG. Reference numeral 1 is a resistance element, and lead wires 3 are provided at both ends thereof via caps 2 (only one of which is shown here). A terminal 4 is attached to the lead wire 3 by welding. The terminal 4 is manufactured by cutting the outer shape and punching a metal flat plate with a molding press and simultaneously bending the metal plate. Reference numeral 5 denotes a voltage detection terminal, one end of which is fixed to a hole 6 formed in the terminal 4 by soldering or caulking.

[Problems to be solved by the device]

 However, the above-mentioned configuration requires the machining of the hole 6, the soldering of the terminal 5, or the manual processing such as caulking in order to provide the voltage detection terminal 5, so that the work is troublesome and the cost is high. There was a problem.

The present invention is intended to solve the above-mentioned conventional problems, and provides a resistor with a voltage detection terminal, which eliminates the manual work for providing the voltage detection terminal and reduces the cost. The purpose is to

[0005]

[Means for Solving the Problems]

 In order to achieve this object, the present invention has a structure in which the voltage detection terminals are integrally provided to the resistance terminals provided at both ends of the resistor by the cut-and-raising process during the forming press.

[0006]

[Action]

 According to the above configuration, when the resistance terminal is molded and pressed, the voltage detection terminal is provided by cutting and raising at the same time, so it is not necessary to manually attach the voltage detection terminal after molding the resistance terminal as in the conventional case. ..

[0007]

【Example】

 Hereinafter, embodiments will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of the present invention. Reference numeral 11 is a resistor, for example, a resistor element is housed in a ceramic case and is filled with cement. Reference numeral 12 denotes a resistance terminal, which is attached by welding to a lead wire 3 provided on both ends of the resistance element 1 via caps 2 as shown in FIG. Reference numeral 13 denotes a voltage detection terminal, which is cut and raised at the same time when the resistance terminal 12 is molded and pressed, and is provided integrally with the resistance terminal 12.

When the resistor having such a configuration is mounted on a printed wiring board and a current is passed between the resistance terminals 12, the voltage across the resistor 11 is detected between the voltage detection terminals 13.

[0009]

[Effect of the device]

 As described above, according to the present invention, when the resistance terminal is molded and pressed, the voltage detection terminal is also formed at the same time, so that the voltage detection terminal is manually attached after molding the resistance terminal as in the conventional case. Therefore, the workability is improved and the cost can be reduced.
