Description

The present invention relates to an electronic component mounted on a printed wiring board, and more particularly to the shape of a terminal of the electronic component.

A conductor pattern is formed on the surface of the printed wiring board. Corresponding to the conductor pattern, the printed wiring board is electrically connected with an IC chip such as a CPU, RAM, ROM, etc., various capacitors, resistors, transistors, etc. from the front or back surface.

When connecting each electronic component to the conductor pattern, the terminal of the component and the conductor pattern can be electrically connected by inserting the terminal of the component into the through hole and soldering.

When the electronic component is placed in close contact with the printed circuit board and soldered so that the terminal protruding from the through hole is electrically connected to the conductor pattern, the solder gas generated during the soldering is reduced to the solder meat. The electrical connection between the conductor pattern and the terminal of the electronic component tends to be insufficient due to slipping out of the raised portion, causing malfunction of the electronic device, heat generation, and ignition.

Therefore, when mounting the electronic component in order to effectively discharge the solder gas, there is one that secures a degassing portion for extracting the solder gas and solders. For example, in Japanese Utility Model Laid-Open No. 61-207070, terminals of electronic components are bent to the opposite sides, inserted into through holes, and attached so that the electronic components do not contact the printed circuit board, or Japanese Utility Model Application No. 1-171724. In the publication, there is shown a device in which a gas vent for removing a solder gas is provided in the lower part of an electronic component.

It is also conceivable that the electronic component is placed in a state of floating from the printed circuit board via a terminal so as not to be in close contact with the substrate, and the terminal is soldered. However, in the case of being supported only by the terminal, if the force is applied in a direction perpendicular to the line connecting the through hole in which the terminal is inserted, the terminal is easily tilted. Therefore, in the invention described in Japanese Utility Model Laid-Open No. 61-207070, the electronic component is mounted in a state of floating from the printed wiring board through the terminals, but the two terminals are bent in opposite directions. It ’s hard to fall down.
Japanese Utility Model Publication No. 61-207070 Japanese Utility Model Publication No. 1-171724

However, when the terminal is bent and arranged, it is weak against a force acting in a direction orthogonal to a line connecting the portions inserted into the through holes of the terminal. When the electronic component and the printed wiring board are general-purpose products, the interval between the through holes into which the terminals of the electronic component of the printed wiring board are inserted does not match the interval between the terminals of the electronic component, and The fall prevention effect is weakened or disappears at all.

In addition, it is easy to form a degassing part for removing the solder gas for a relatively large electronic component, but it forms a degassing part having a sufficient degassing effect for a small electronic component. This is very troublesome, and it takes time and cost to manufacture electronic components. Depending on the shape and configuration of the electronic component, it may be difficult to form a gas vent.

Therefore, the present invention is an electronic component that is electrically connected to a conductor pattern by soldering by inserting a terminal into a through-hole provided in a printed wiring board, without using a complicated structure or a special member, An object of the present invention is to provide an electronic component that effectively discharges solder gas, prevents contact failure between the terminal and the conductor pattern, and is difficult to collapse.

Provided is an electronic component characterized by being formed in a spiral shape that swivels.

According to this configuration, since the terminals of the electronic component are pivotally attached to the electronic component, even if an external force is applied to the electronic component, the direction of the external force can be dispersed by the terminal, so that it is difficult to fall down. Thereby, even if the terminal is fixed to the through hole of the printed wiring board in a state where the electronic component is floated from the printed wiring board, the electronic component can be prevented from falling.

It is possible to suppress the occurrence of soldering failure due to the solder gas generated when soldering. That is, it is possible to suppress the occurrence of poor contact between the conductor pattern formed on the printed wiring board and the terminal, and it is possible to suppress the occurrence of malfunctions such as malfunction, heat generation due to short circuit, and ignition.

In addition, since the turning angle of the terminal is 90 °, the terminal is not easily tilted regardless of the direction of the force acting on the electronic component. Moreover, since the terminal is formed by spirally turning, the manufacturing is easy and the manufacturing cost can be reduced.

That is, it is possible to suppress the occurrence of poor contact between the conductor pattern formed on the printed wiring board and the terminal, and it is possible to suppress the occurrence of malfunctions such as malfunction, heat generation due to short circuit, and ignition.

By turning the terminal at an angle greater than 0 ° and not greater than 90 °, it is possible to arbitrarily set a direction in which the electronic component is particularly difficult to fall. When it is mounted on the printed circuit board, it knows the direction in which the force is applied to some extent, and in normal electronic parts, it must be attached so that it can easily fall in the direction in which the force is applied. By selecting the component, the electronic component can be prevented from falling.

When turning at an angle larger than 90 °, the terminals are likely to come into contact with each other, causing problems such as short-circuiting and discharging, and it is sufficient if the turning angle of the terminal is between 0 ° and 90 ° or less. An effect can be obtained.

In addition, electronic components such as a transistor T, a resistance member R, and an electrolytic capacitor C are arranged on the surface FB.

As shown in FIG. 1, an electrolytic capacitor C which is an example of an electronic component according to the present invention has a terminal 2 inserted in a through hole TH. As will be described later, a portion protruding from the through hole TH of the terminal 2 is electrically connected to the conductor pattern Pt by soldering. Similarly, the transistor T and the resistance member R shown in FIG. 1 have terminals passing through the through holes TH, and the protrusions are electrically connected to the conductor pattern Pt by soldering. In this way, electronic components (transistor T, resistance member R, electrolytic capacitor C, etc.) are mounted on the printed circuit board MB,

2 is formed. In the printed wiring board MB, a through hole TH penetrating from the front surface FB to the back surface RB is formed.

As shown in FIG. 3B, the terminal 2 of the electrolytic capacitor C is inserted from the surface FB side of the through hole TH. The conductor pattern Pt and the portion 21 protruding from the through hole TH of the terminal 2 are connected and fixed so as to be in a conductive state by welding the solder 3.

By changing the turning angle, it tends to fall down in the direction orthogonal to the line connecting the end portions 41 of the terminals 4 (arrow ef direction), but in return, the end portions 41 of the terminals 4 are used. It becomes even more difficult to fall in the direction of the line connecting them (arrow line gh direction). Such electrolytic capacitor C
2 can be used in the case where a problem occurs when it falls in the direction connecting the end portions 41 of the terminals 4 (for example, a cooling fan is attached). .

That is, by attaching the terminals 51 and 53 at both ends so as to turn (here, a turning angle of 90 °), it is possible to prevent the terminals from falling down. Although not shown, when the central terminal 52 is not at the center of the terminals 51 and 53 on both sides, the terminals 5 (51, 52 and 53) are not easily fallen by turning around the center of the main body. Electronic components can be configured.

An electronic component having two or three terminals is described as an example of an electronic component to which the present invention is applied. However, the present invention is not limited to this, and a plurality of terminals are arranged in a straight line or a substantially straight line. Electronic parts can be widely adopted. However, if the number of terminals increases too much, the length of the terminal becomes too long, which may become unstable or take up too much space.
