DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal block for a motor configured to store a capacitor in a capacitor storage section provided in a terminal block body.

[0002]

2. Description of the Related Art For example, in a motor (condenser induction motor) used in a fan device, a terminal block is mounted on one end of a stator, and a capacitor is stored in a capacitor storage section formed on the terminal block. I have. In this case, the capacitor is fixed to the terminal block by an adhesive.

However, when the capacitor is fixed to the terminal block with an adhesive as described above, it takes time for the adhesive to cure, and there is a possibility that the adhesive may adhere to other parts. The mounting work was inferior, such as difficulty in accurate positioning.

Further, there has been provided a capacitor in which mounting legs having screw holes are integrally provided, and the capacitor is mounted on a terminal block by screwing. According to this, the capacitor can be fixed to the terminal block without using an adhesive. However, even in this case, there are disadvantages that screws and the like are required, the number of parts is increased, and screwing work, which is a fine work, is required, and the mounting work is troublesome.

[0005] Under such circumstances, when mounting the capacitor to the terminal block, a configuration as shown in FIGS. 13 and 14 has been considered for the purpose of simplifying the mounting. In FIG. 13, the capacitor 1 is
The package 2 is molded with the package 2, and is configured such that two leads 1 a protrude from the front end surface of the package 2. A mounting leg 3 extending downward is provided integrally on the lower surface of the package 2, and an engagement hole 3 a is formed at a lower end of the mounting leg 3.

[0006] The terminal block 4 is formed by insert-molding a conductor 7 made of a metal plate with a synthetic resin, and has, on its upper surface, a capacitor accommodating portion for accommodating the capacitor 1 as shown in FIG. 5 has a substantially rectangular shape corresponding to the outer shape of the package 2 of the capacitor 1 and is formed in a concave shape. An insertion hole 5b into which the mounting leg 3 is inserted is formed at a position corresponding to the mounting leg 3 of the capacitor 1 at the bottom 5a of the capacitor housing portion 5, and the edge of the insertion hole 5b is formed at the edge of the insertion hole 5b. Is provided integrally with a mounting piece 6 extending continuously downward from the edge thereof. A spherical engaging projection 6a is provided below the mounting piece 6.

Is inserted into the insertion hole 5 b of the capacitor housing 5, the engagement hole 3 a of the mounting leg 3 engages with the engagement projection 6 a of the mounting piece 6, whereby the capacitor 1 can be mounted. Then, by electrically connecting the lead 1a of the capacitor 1 to the capacitor connecting portion 7a exposed in the capacitor housing portion 5 of the conductor 7 by spot welding, electrical and mechanical connection can be achieved.

[0008]

However, in the above-described device, the bottom 5a of the capacitor housing 5 in the terminal block 4 is thin because the capacitor housing 5 is formed in a concave shape. In addition, since the conductor 7 is not insert-molded, warpage tends to occur. Therefore, if the bottom 5a of the capacitor housing 5 is warped, a gap is generated between the capacitor 1 and the terminal block 4, which causes a backlash. In addition, there is also a problem that the capacitor 1 vibrates due to the play, thereby generating an abnormal sound.
