Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coil terminal block used for a coil with a terminal block in which a copper wire is wound around a ring core, and a toroidal coil using the tip of the copper wire as a lead wire is attached to the terminal block.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 4, a terminal block 3 is attached to a toroidal coil in which a copper wire 2 is wound around a ring core 1, and a lead wire 4 is drawn out below the terminal block 3 to manufacture a coil with a terminal block as shown in FIG. As shown in Fig. 3, a toroidal coil 7 is prepared by winding a copper wire around the ring core 1, the lead wire 4 is inserted into the lead wire through hole 6 provided below the terminal block 3, and the adhesive is applied to the terminal block 3. Although the terminal block 3 and the toroidal coil 7 were fixed with the agent 5, the work of inserting the lead wire 4 into the through hole 6 and the time of applying the adhesive agent 5 to the terminal block 3 are liable to be dirty and easily mounted on the board. In that case, there was a problem that the lead wire 4 floated up.

[0003]

[Problems to be solved by the device]

 The object of the present invention is to solve the above-mentioned problems, to create a coil with a terminal block, without requiring skill in assembling, good assembling workability, and using a coil on the terminal block without using an adhesive or the like. It aims to supply a coil terminal block that has a structure in which the lead wire does not easily float when mounted on a board.

[0004]

[Means for Solving the Problems]

 In order to solve these problems, the present invention inserts the lead wire 4 into the pitch groove by the convex portion 12 and the concave portion 11 of the terminal block 3 shown in FIG. Since the lead wire 4 is bent in a curved shape to fix the coil, work such as bonding work and through hole insertion work is unnecessary, and we devised a terminal block with a structure that can eliminate troublesome work. Specifically, the terminal block 3 having a resin hinge 9 and a lid 10 integrally formed with the mounting base 8 for mounting the coil shown in FIG. The convex portion 12 of the portion 10 gives a curved deformation to the lead wire 4 of the coil to fix it, and prevents the lead wire from floating during mounting on a substrate. At the same time, the terminal block having a structure in which the pitch between the lead wires can be secured by inserting it in the pitch groove 15 is provided.

That is, the present invention is a rectangular parallelepiped base, which is provided with an arcuate recess in the center, and a toroidal coil is installed in the recess, and the end of the winding is pulled out from the lower surface of the recess to the lower surface of the base. , The coil is fixed to the terminal block to form a coil with the terminal block.The terminal block is a flat plate with the mounting block that has a recess for installing the toroidal coil in the center of the top surface. It is composed of two lids with a convex portion on the lower inside, and the lid and the mount are connected by a hinge integrally formed at the corner of the side of the mount, and the other end of the lid is connected to the other end. Hooks for fixing the lid part to the mount part by being pushed into a groove provided on the side surface of the other end of the mount part, and a convex part provided at the lower center of the cover part. At the position corresponding to the protrusion, the lead used when the protrusion of the lid is pushed A structure is provided in which a recess having a size equal to the wire diameter is provided, and a pitch groove having a width and depth approximately the same as the wire diameter of the lead wire is machined at the center lower end of the recess of the mounting base. It is a characteristic coil terminal block.

[0006]

[Action]

 Since the lead wire is deformed in a curved shape by the recesses and pitch grooves provided on the mounting base part of the terminal block and the convex parts provided on the lid part, the lead wire of the toroidal coil is not deformed from the terminal block. Since the lid is hooked, the coil can be fixed by fixing the lead wire with one touch, and the pitch of the lead wire can be secured.

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing the assembly of a coil with a terminal block using the coil terminal block according to the embodiment of the present invention. FIG. 2 is an external perspective view of the coil with terminal block shown in FIG. FIG. 3 is a sectional view of the coil with terminal block shown in FIG. In FIG. 1, the toroidal coil 7 is installed on the mounting base portion 8 of the terminal block 3, and the projection 10 for fixing the lead wire is provided on the lid portion 10 with the hinge 9 integrally formed with the mounting base portion 8 as a fulcrum. . By closing the lid, the lead wire 4 is pressed, and the lead wire 4 is pushed into the recess 11 provided in the mounting base portion 8 and the lead wire 4 is pushed into the pitch groove 15 while the lead wire 4 is curvedly deformed. The hook 13 and the groove 14 provided in the mounting base 8 are fitted together. As shown in FIG. 3, the lead wire 4 is curvedly deformed by the convex portion 12 of the lid portion 10 and the concave portion 11 of the mounting base portion 8 to prevent the lead wire 4 from floating due to a force applied from below. As described above, the toroidal coil 7 is installed on the mounting base portion 8, the hooks 13 of the lid portions 10 on both sides are fitted into the grooves 14 of the mounting base portion 8, and the lead wire 4 is fixed to form the coil with the terminal base into the shape shown in FIG. Complete.

A coil with terminal block for toroidal type according to the present embodiment was used to prepare a coil with a toroidal type terminal block, and it was easily assembled without using an adhesive, and the floating at the time of mounting on the board was also suppressed. In addition, the lead wire pitch was constant, no rework was required during assembly, and a product with improved assemblability and mountability was obtained.
