[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a cap with a terminal block for a toroidal coil of a toroidal coil mounted on an electronic device.

[0002]

[Prior Art]

 Conventionally, in order to fix this type of toroidal coil (hereinafter referred to as a coil) to a board on which an electronic circuit is mounted, the lead wire of the winding end of the toroidal coil is simply attached to the board and fixed by soldering. If the winding wire is thin, it may be broken or the coil to the mounting board may be fixed in an unstable state. In order to ensure electrical insulation, the coil was covered with a heat-shrinkable tube, but defects such as breakage of the heat-shrinkable tube and formation of holes occurred.

[0003]

[Problems to be solved by the device]

 The present invention uses a cap with a terminal block to cover the coil in order to fix the coil to the substrate to eliminate these drawbacks and to secure the electrical insulation characteristics. An object of the present invention is to provide a cap with a terminal block for a toroidal coil in which a terminal block having terminals implanted therein and a cap having a claw that engages with a substrate are engaged and assembled.

[0004]

[Means for Solving the Problems]

 According to the present invention, a claw that engages with a hole of a substrate is attached to both sides of the coil to fix the coil to the substrate, and a cap having an almost same R surface on the outer circumference of the coil and having an electric insulation characteristic that covers the entire surface of the coil. And the terminal block with the cap engaged and fixed in place, with pin terminals planted and a stand-off between the pin terminals, connect the coil winding ends to the pin terminals on both sides of the center of the terminal block and solder them. Then, the cap is fitted to the terminal block, the coil is engaged and fixed to the substrate by the claws attached to both ends of the cap, and the electric insulation characteristic is secured by the cap.

That is, according to the present invention, a terminal having a standoff in the center and pin terminals for twisting winding terminals of a toroidal coil placed on the upper surfaces of both side surfaces is implanted, and a terminal having lateral grooves on the side surfaces of the pin terminal. The base and the shape along the outer circumference of the toroidal coil, the side surface and the peripheral surface are made of electrically insulating resin, the lower surface both ends are provided with the claws for engaging the board, and the terminal block retainer for engaging the terminal block is provided inside. Place the toroidal coil on the terminal block with the attached cap, connect the winding ends to the pin terminals, cover the toroidal coil with the cap, engage the cap with the terminal block retainer, and engage the cap's claws and pins. A cap with a terminal block for a toroidal coil, which is configured to be locked to a substrate by a terminal.

[0006]

[Action]

 A standoff is attached to the center by engaging a cap that has claws that hold the board on both ends of the resin that has electrical insulation properties that covers both sides and the top of the coil, and terminal block retainers that are attached to both ends of the cap. A cap with a terminal block for a toroidal coil consisting of a mounted terminal block with at least two pin terminals planted, the coil is placed on the terminal block, and the coil winding end is mounted next to the pin terminal. Pull out to the pin terminal side through the horizontal groove, connect the winding terminal to the pin terminal, connect the coil to the terminal block with a cap, engage the terminal block and cap with the terminal block retainer, and attach to both ends of the cap. The toroidal coil is locked and mounted on the board by the claws.

In FIG. 1, the toroidal coil 2 is placed on the terminal block 7, and the winding terminals 5 of the toroidal coil 2 are passed through the lateral grooves 9 attached to both sides of the pin terminal 4 of the terminal block 7 shown in FIG. Attach the cap 1 with the toroidal coil fixed to the terminal block 7 by twisting it to 4, and the semicircular shape along the outer circumference of the toroidal coil with the claws 3 that engage with the board on both ends of the bottom surface of the terminal block inside the cap. The terminal block retainer 10 that engages with both ends of a certain terminal block engages the terminal block with the lower surface of the cap, and the toroidal coil is fixed in the cap by the terminal block 7 and the cap 1. Further, the toroidal coil is locked and attached to the substrate 6 by the claw 3 of the cap 1.

[0008]

[Effect of the device]

 The cap with terminal block for toroidal coil according to the present invention has a structure in which the toroidal coil is assembled by engaging the terminal block with pin terminals attached and the toroidal coil mounted and fixed to the cap with both ends attached. The coil is fixed with the terminal block, the winding is mounted on the substrate through the pin terminals, the outer circumference of the toroidal coil engages the inner peripheral surface of the cap and the terminal block, and the electrical insulating material covering the toroidal coil is used. Since the structure is such that both ends of the cap are engaged and fixed to the board, the toroidal coil terminal block for insulation of the toroidal coil and the installation of the toroidal coil on the board can prevent the occurrence of coil insulation and disconnection defects. It can be a cap.
