Description
Technical Field
The present application relates to an inverter device.
Background
In an inverter device used in a vehicle-mounted manner, when a flexible printed circuit board is used as a signal transmission means between control devices in the inverter device, if the number of transmission signals increases, the flexible printed circuit board connector is enlarged in the width direction, and therefore, the space efficiency in the inverter device is deteriorated.
As a countermeasure, it is considered that two flexible printed boards are arranged in an overlapping manner in the up-down direction to prevent the space efficiency in the width direction from deteriorating, but an inverter device for mounting on a vehicle mounted on an electric vehicle or a hybrid vehicle is sometimes mounted in a place where the vibration environment is severe, and when two flexible printed boards are overlapped, the flexible printed boards may shake due to vibration or may be damaged or broken due to contact with other components in the inverter device for mounting on the vehicle. In addition, when the electronic component is located in the periphery, the flexible printed circuit board is close to the electronic component and is susceptible to noise.

Detailed Description
Hereinafter, embodiment 1 of the present invention will be described with reference to the drawings. In the drawings, the same reference numerals denote the same or corresponding parts.
Fig. 1 is a perspective view showing an inverter device according to embodiment 1. Fig. 2 is a front view showing an inverter device according to embodiment 1. Fig. 3 is a cross-sectional view taken along line a-a of fig. 2 showing the inverter device according to embodiment 1. Fig. 4 is a cross-sectional view taken along line B-B of fig. 3 showing the inverter device according to embodiment 1. Fig. 5 is an enlarged sectional view of a main portion of an inverter device according to embodiment 1.
In the above drawings, reference numeral 1 denotes a first control board on which a first control group is mounted, reference numeral 2 denotes a first control board connector on which the first control board 1 is mounted, reference numeral 3 denotes a second control board on which a second control group is mounted, reference numeral 4 denotes a second control board connector on which the second control board 3 is mounted, reference numeral 5 denotes a first flexible printed board connector mounted on the first control board 1 and connected to the first control board connector 2, and reference numeral 6 denotes a second flexible printed board connector mounted on the second control board 3 and connected to the second control board connector 4.
A first protrusion 13 and a second protrusion 14 are provided in the holding member 7 made of a resin material by insert molding, a first bush 15 is fitted to the first protrusion 13, and a second bush 16 is fitted to the second protrusion 14. The first protrusion 13 is provided with a first pin 17, and the second protrusion 14 is provided with a second pin 18. These members are members for mounting the holding member 7, the first flexible printed circuit board 11, the second flexible printed circuit board 12, and the like to an inverter ground portion in an inverter device described later.
The operation will be described next. Since the first flexible printed circuit board 11 is inserted into the cylindrical first space 9 of the holding member 7 and held by the inner wall of the partition body 8 in the first space 9 and the second flexible printed circuit board 12 is inserted into the cylindrical second space 10 of the holding member 7 and held by the inner wall of the partition body 8 in the second space 10, the shaking caused by the vibration of the first flexible printed circuit board 11 and the second flexible printed circuit board 12 can be suppressed and the flexible printed circuit boards can be held locally.
Further, for example, the first flexible printed board 11 can be firmly held by the holding member 7 by fixing the inner wall of the partition body 8 in the cylindrical first space portion 9 of the holding member 7 with an adhesive tape. For example, the second flexible printed board 12 can be firmly held by the holding member 7 by fixing the inner wall of the partition body 8 in the cylindrical second space portion 10 of the holding member 7 with an adhesive tape.
Therefore, since the first flexible printed circuit board 11 and the second flexible printed circuit board 12 are fixed to the holding member 7 by the adhesive tape, the vibration generated by the vibration inside the holding member 7 can be reduced, the possibility of the first flexible printed circuit board and the second flexible printed circuit board 12 interfering with each other and damaging each other can be eliminated, and high reliability can be obtained.
In this way, since the first flexible printed circuit board 11 can be inserted and held in the cylindrical first space portion 9 of the holding member 7 and the second flexible printed circuit board 12 can be inserted and held in the cylindrical second space portion 10 of the holding member 7, it is possible to arrange the flexible printed circuit boards having a structure in which two flexible printed circuit boards are stacked, and it is possible to improve the space efficiency of the inverter device and to cope with the multi-polarization of the connector. Further, as shown in fig. 1, the first flexible printed circuit board 11 and the second flexible printed circuit board 12 are fitted to the first control board connector 2 and the second control board connector 4 via the first flexible printed board connector 5 and the second flexible printed board connector 6, and thus can favorably act on vibration as compared with the board assembly type.
Further, the first flexible printed board 11 is held by the partition body 8 in the first space portion 9 of the holding member 7 made of a resin material, and the second flexible printed board 12 is held by the partition body 8 in the second space portion 10 of the holding member 7, and therefore, the first flexible printed board 11 and the second flexible printed board 12 are fixed so as to maintain a mutual interval by the partition body 8.
Therefore, the first flexible printed circuit board 11 and the second flexible printed circuit board 12 can be formed in a two-piece structure without the first flexible printed circuit board 11 and the second flexible printed circuit board 12 contacting each other, and space efficiency can be achieved.
Further, since the flexible printed circuit board 11 and the second flexible printed circuit board 12 are not in contact with other components disposed inside the inverter device for vehicle mounting, high reliability can be obtained without causing damage or disconnection of the flexible printed circuit boards.
Further, since the first bush 15 of the holding member 7 fitted to the first protrusion 13 and the second bush 16 fitted to the second protrusion 14 are resin-molded products, by providing a female screw by using another component, screwing can be achieved, and the number of components can be reduced.
As shown in fig. 3 to 5, the steel plate 19 is inserted into the resin of the holding member 7 made of a resin material along the shape of the holding member 7. The steel plate 19 is fixed to an inverter ground in an inverter device described later, and therefore has an electromagnetic shielding effect, and can suppress noise emitted from the first flexible printed circuit board 11 and the second flexible printed circuit board 12 and noise generated from electronic components.

The first flexible printed board 11 is fixed vertically and horizontally by the engagement of the first engaging concave portion 20 and the first engaging convex portion 21.
As shown in fig. 9, second engagement concave portions 22 having a notch shape are formed at both side end portions of the second flexible printed board 12 so as to be shifted in position, second engagement convex portions 23 are formed at positions corresponding to the second engagement concave portions 22 in the inner wall of the first space portion 9 of the holding member 7 on the opposite side of the partition body, and the second flexible printed board 12 is positioned and assembled by engaging the second engagement concave portions 22 of the second flexible printed board 12 with the second engagement convex portions 23 of the first space portion 9 of the holding member 7 on the opposite side of the partition body. The second flexible printed board 12 is fixed vertically and horizontally by the engagement of the second engaging concave portion 22 and the second engaging convex portion 23.
In this way, when the first flexible printed circuit board 11 and the second flexible printed circuit board 12 are inserted into the first space portion 9 and the second space portion 10 of the holding member 7, the positioning of the first flexible printed circuit board 11 and the second flexible printed circuit board 12 is facilitated, and the assembling property is improved. The improvement of the assembling property can shorten the manufacturing rhythm and reduce the cost.
