[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to axial parts, and more specifically to the electrode leg structure of axial parts. It is related.

[0002]

[Prior art]

  Conventionally, the electrode leg structure of the axial part has been constructed as shown in FIG. As shown in FIG. 4 (a), the axial component 21 composed of electrodes is an electrode projecting at both ends. The leg 22 is provided, and each electrode leg 22 is bent in the same right angle direction from the vicinity of the component 21. ing.   The mounted state on the printed circuit board is as shown in FIG. 3 has a plurality of circuit patterns 24 on one surface, and each of the plurality of circuit patterns 24 has another The component 21 is mounted on the other surface of the printed circuit board 23 by providing the through hole 25 penetrating to the surface. At the same time, the respective electrode legs 22 are fitted into the plurality of through holes 25 and protrude from the through holes 25. Each electrode leg 22 and the circuit pattern 24 are electrically connected by soldering 26. There is.

[0003]

[Problems to be solved by the device]

  The above-mentioned conventional drawbacks are that the printed circuit board surface and the axial component come into contact with each other, A small gap is left between each electrode leg protruding from the component and the same printed circuit board surface. Therefore, the curved measuring element at the tip of the measuring probe is equipped on the measuring instrument. It cannot be hooked on the electrode leg, and therefore it can When adjusting or measuring various electric circuits from the component side, the electrodes of the axial components Workability that requires performing the adjustment and measurement while applying the measuring element to the leg There was a problem that work efficiency was poor.

[0004]

[Means for Solving the Problems]

  In order to solve the above-mentioned problems, the present invention provides an array of electrodes with protruding electrode legs at both ends. It consists of axial parts, and each of the electrode legs is placed in the same orthogonal direction from the vicinity of the same part. Along with the bending, there is a bending space between the bending part and the parts in the opposite direction to the bending. It is characterized in that the protruding portion is formed.

[0005]

[Action]

  According to the above configuration, each electrode leg protruding from both ends of the axial component is attached to the same component. Bend in the same right angle direction from the vicinity of the Adjustment of the electric circuit by forming a protrusion with a bending space in the opposite direction When measuring or measuring, pass the measuring element from the measuring instrument through the same space and hook it on the protrusion. It is something that can be done.

[0006]

【Example】

  An embodiment of the present invention will be described below with reference to the drawings.   As shown in the side view in Fig. 1, the axial parts 1 such as resistors and diodes are Each of the electrode legs 2 protruding from the same, and each electrode leg 2 from the vicinity of the component 1 at the same right angle. Bend in the same direction and then in the opposite direction to the same bend between the part and the part 1. A protrusion 4 having a space 3 is formed on each electrode leg 2.

[0007]   Next, the state of mounting the axial parts on the printed circuit board is shown in the partial cross section in FIG. As shown in the side view including, the printed circuit board 5 is provided with a plurality of circuit patterns 6 on one surface. The circuit pattern 6 of 1 is provided with a plurality of through holes 7 that penetrate to the other surface, and the component 1 is printed. While mounting on the other surface of the substrate 5, the respective electrode legs 2 are inserted into the plurality of through holes 7, Each electrode leg 2 protruding from the through hole 7 and each circuit pattern 6 are used as solder dips. Automatic soldering 8 by or soldering with a soldering iron 8 is done and electrical connection is completed Even if the printed circuit board 5 surface and the component 1 are in contact with each other, the space provided in each electrode leg 2 The protruding portion 4 formed of the interspace 3 is projected and remains on the surface of the printed circuit board 5.

[0008]   According to the above configuration, the curved shape of the tip of the measuring probe provided in the measuring device (not shown) The state in which the formed measuring element is hooked on the electrode leg is as shown in the perspective view of FIG. If various electric circuits are adjusted and measured from the side of various electric parts mounted on the printed circuit board 5. First, pass the tip of the element 9 through the space 3, and then hook the curved portion on the protrusion 4. Therefore, when there is a potential difference between the respective electrode legs 2, one of the electrode legs 2 2 to the first probe 10 and the other electrode leg 2 to the second probe 11 respectively. However, the respective potential differences can be measured at the same time.

[0009]   In addition, even if the protruding portion 4 is formed only on one of the electrode legs 2, the above-described configuration is established. It is a thing.

[0010]

[Effect of device]

  As described above, the present invention uses the same electrode legs that project from both ends of the axial component. Bend from the vicinity of the parts in the same right angle direction, and make sure that the same parts are By forming a protrusion with a bending space in the direction opposite to the bending, When making adjustments and measurements, easily pass the measuring element from the measuring instrument through the same space to the protrusion. Since it can be hooked on the Efficiency and can be improved.
