Abstract

(57) [Summary] [Purpose] Take out the lead wire connected to the power supply terminal located on the side of the power module straight without bending. [Structure] The lead wire is not bent by bending the power supply terminals 6 horizontally attached to both sides of the lower case 3 of the power module at a predetermined position at a right angle.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a power module, and more particularly, to a structure of a power supply terminal.

[0002]

[Prior art]

 Conventionally, a power module such as an inverter is equipped with a giant transistor and a rectifying diode for AC-DC conversion for controlling three-phase AC waveforms and peripheral devices, and is controlled by a microcomputer. FIG. 3 is a view of a conventional power module, (a) is a front view and (b) is a side view. In the figure, reference numeral 5 is a power unit substrate, on which the lower case 3 is arranged. The power supply terminals 4 are mounted on both sides of the lower case 3, and the upper case 2 is disposed on the upper part. The signal terminal 1 is mounted on the upper surface of the upper case 2. The power module configured as described above is used by being attached to a predetermined device. Receptacles with lead wires are inserted into the power supply terminal 4 and the signal terminal 1 and connected to a predetermined device. Since the lead wire connected to the power supply terminal 4 is pulled out in the upward direction of the power module, if the power supply terminal 4 is bent at a right angle, the lead wire can be taken out smoothly without bending, but at present, it is a lead wire. Has a problem of bending at the power supply terminal 4, that is, at the side of the power module.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the conventional problems described above, and eliminates the bending of the lead wire straightly by bending the power supply terminal horizontally mounted on the side portion of the power module at a predetermined position at a right angle.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, a power section substrate on which a power element is mounted, a lower case arranged on the upper side of the power section board, and a control section board arranged on the upper side of the lower case, In a power module including an upper case mounted on the lower case so as to enclose the control unit board and a plurality of power supply terminals horizontally mounted on both sides of the lower case, the power supply terminal is predetermined. The present invention provides a power module characterized by being bent upward at a right angle or a substantially right angle at the position.

[0005]

[Action]

 According to the above configuration, the lead terminals are not bent by bending the power supply terminals horizontally attached to both sides of the lower case of the power module at a predetermined position at a right angle.

【Example】

 Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows an embodiment of the power module of the present invention. (A) is a front view, (b) is a side view, and FIG. 2 is a front sectional view of the power module of the present invention. In the figure, 3 is a lower case, and a power supply terminal 6 is arranged on the side. Reference numeral 2 is an upper case, on which the signal terminal 1 is arranged. In FIG. 2, reference numeral 5 is a power unit substrate, on the upper surface of which a power element (not shown) is mounted and hardened with an inner coat resin 7. The lower case 3 is disposed above the power unit substrate 5, and the control unit substrate 8 is disposed above the lower case 3. Electronic components such as a semiconductor element 9 are mounted on both surfaces of the control unit substrate 8. The power unit substrate 5 and the control unit substrate 8 are electrically connected by the connection terminals 10. Reference numeral 2 denotes an upper case, which is arranged above the lower case 3 so as to enclose the control unit substrate 8. The power supply terminal 6 arranged on the side of the lower case 3 is connected to a power element or the like. The power supply terminal 6 is bent at a predetermined position upwards at a substantially right angle. Therefore, when a receptacle with a lead wire is inserted into the power supply terminal 6, the lead wire is pulled out upward without bending the power module. be able to.

[0007]

[Effect of device]

 As described above, in the present invention, since the power supply terminal 4 is bent at a right angle, the lead wire connected to the power supply terminal is pulled straight out in the upward direction of the power module. The effect of eliminating bending at the side of the module is great.
