Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a case with a terminal block that forms a toroidal coil to be mounted on an electronic circuit.

[0002]

[Prior Art]

 As shown in Fig. 4, a case with a terminal block used in a conventional toroidal coil has a terminal block 3 having a lead terminal fixing groove 9 for fixing a lead terminal of a winding and a soft magnetic toroidal core inside. Insulation case 1 in which a separation plate 6 for separating the two windings is attached to the center is integrated with the terminal block 3 by the terminal mounting portion 2. However, if the terminal block is accidentally damaged when the lead terminal is attached to the terminal block, the entire case with terminal block becomes unusable.

[0003]

[Problems to be solved by the device]

 In order to eliminate these drawbacks, the present invention makes it possible to easily perform winding on the insulating case, and to replace only the terminal block when the terminal block is damaged. It is possible to provide a split type terminal block mounting case by using an insulating case with a terminal block mounting part that pursues ease of work and a terminal block with a fitting recess that fits into the terminal block mounting part. To aim.

[0004]

[Means for Solving the Problems]

 The present invention is a terminal block mounting part that houses a soft magnetic toroidal core and is integrated with an insulating case made of a resin molding material that winds around the outer circumference, and a lead terminal that is installed on the board and fixes the winding lead terminal. The terminal block with the fixing groove is separated from the terminal block.The insulating case has a tapered terminal block mounting part with narrowed tip and tabs on both tapered surfaces, and the center of the terminal block. Insert the terminal block mounting part into the elastic terminal block with the fitting recess with a narrow bottom and the claw locking holes on both sides of the fitting recess, and mount it on both sides of the terminal block mounting part. The claw and the claw locking hole are fitted and fixed.

That is, the present invention provides a toroidal core of a soft magnetic material having a tapered surface on both side surfaces with a narrowed tip and a terminal block mounting portion on which a projection-shaped pawl is mounted in parallel with the base plate mounting surface on the tapered surface. An insulating case, a fitting recess for fitting the terminal block mounting part with a narrow bottom in the center, claw locking holes for locking the claws on both sides of the fitting recess, and leads on both sides. With a terminal block with a terminal mounting groove, the terminal block mounting part integrated with the insulating case is press-fitted into the fitting recess of the terminal block, and the claw and claw locking hole are fitted and fixed. It is a case.

[0006]

[Action]

 The insulating case that houses the soft magnetic toroidal core has a structure in which the terminal block mounting part that is smaller than the diameter of the insulating case is integrated, so winding work to the insulating case is easy and the terminal block mounting part does not The tip has a narrow taper, and the tapered surface of the taper mounting part has a protruding claw that extends in the direction parallel to the board surface.The claw fits the terminal block and the insulating case, so the bottom surface is in the center of the terminal block. A fitting recess with a narrow upper surface is provided, and locking holes are provided on both sides of the fitting recess to engage with pawls attached to the taper part of the insulating case. Also, because the terminal block is made of elastic resin material, when pushing the terminal block mounting part integrated with the insulation case into the fitting recess of the terminal block, the bottom surface of the fitting recess extends and the terminal block mounting part The claw and the claw locking hole of the fitting recess are engaged with each other, and the insulating case and the terminal block are tightly fitted and firmly fitted and fixed. The claws attached to the tapered part of the terminal block mounting part and the claw locking holes on both sides of the fitting recess of the terminal block are configured to lock with each other when the terminal block mounting part is pushed into the fitting recess.

【Example】

 FIG. 1 is an external perspective view showing a case with a terminal block according to the present invention, in which a toroidal core made of a soft magnetic material is housed in an insulating case 1, and a separating plate 6 is used as a boundary to form two windings in this embodiment. Are separately wound in the same winding direction. Both ends of the terminal block mounting portion 2 have narrow tapered ends, and projecting claws 5 parallel to the terminal block surface are attached to the tapered surfaces on both sides. A terminal block 3 is arranged below the insulating case. The terminal block 3 is made of an elastic material made of resin, and a fitting recess 7 having a tapered bottom is provided in the center. Claw locking holes 8 for locking the claws 5 on both sides of the terminal block mounting portion are attached to both sides of the above. FIG. 2 shows a sectional view of a portion of the terminal block 3 in which the terminal block mounting portion 2 of the insulating case 1 and the fitting recess 7 of the terminal block 3 are fitted, and the claw 5 and the claw locking of the terminal block 3 The hole 8 is fitted and locked. FIG. 3 is a completed drawing of a toroidal coil using the case with terminal block of the present invention in which the winding 4 is applied to the insulating case 1 and the lead terminal 4a is fixed to the terminal block 3 in the lead terminal fixing groove 9 of the substrate. .

[0008]

[Effect of the device]

 In the case with terminal block according to the present invention, the terminal block and the insulating case can be separated from each other, so that it is easy to wind the insulation case, and even if the terminal block is damaged, the terminal block can be replaced with a toroidal case. It is now possible to provide a case with a terminal block that can be reused without affecting the coil.
