Description

[Detailed Description of Device] a. DISCLOSURE OF THE INVENTION [Industrial field of use] The present invention provides a terminal for an electronic component provided with a case for housing an electronic component such as a coil used in the electronic component and a terminal block for fixing the lead terminal of the electronic component at a predetermined position. Of the case with a stand,
The present invention relates to a lead terminal fixing structure.

[Conventional technology]

For electronic parts used in electronic equipment, such as coils and chokes, which have a relatively large current, the winding wire material is thick, so it is common to use the tip of the winding as it is as a lead terminal for external connection. there were. Therefore, in this type, for example, a case with a terminal block for electronic parts, which is provided with a case that insulates the core used for the coil from the winding to house and cover the core, and a terminal block that fixes the tip of the winding as a lead terminal However, it has been generally used from the past.

A conventional case with a terminal block for electronic parts is provided with a ring case for accommodating and insulating a ring core in an upper part and a rectangular flat plate-like terminal block for fixing a terminal in a lower part, and a plan view of a bottom surface in FIG. As shown in Fig. 2, the ends of the windings wound on the ring case 14 are fixed to the terminal block 11 as lead terminals 13.
, And insert the lead terminal 13 into it as shown by arrow 15,
It was fixed with an adhesive. Moreover, the terminal block of the lead terminal 13
The width of the notch 12 was made as narrow as possible to the diameter of the lead terminal 13 in order to securely fix it to 11, and the internal termination was formed in a hole having a diameter slightly larger than the diameter of the lead terminal 13.
Therefore, when the lead terminal 13 is inserted into the notch, there are problems that the lead terminal 13 is bent or scratched to deteriorate the quality, or that a work time for inserting and bonding is required.

[Problems to be solved by the device]

The present invention eliminates such problems, and when inserting and fixing the lead terminal to the terminal block, does not cause bending or flaws on the lead terminal, and does not require adhesive work, and can save the working time. It is intended to provide a case with a terminal block for parts.

B. Configuration of the Invention [Means for Solving the Problems] The present invention integrally includes a case for mounting and housing electronic components and a terminal block provided with a notch for fixing lead terminals of the electronic components in predetermined positions. In the provided case with a terminal block for electronic parts, a slide plate having a terminal groove for fixing the lead terminal at a predetermined position is inserted into a guide integrally provided on a lower surface of the terminal block, and the lead terminal is connected to the terminal. It is a case with a terminal block for electronic parts, which is fixed by a notch of the table and a terminal groove of the slide plate.

[Action]

Insert the slide plate with the terminal groove into the guide on the lower surface of the terminal block, insert the lead terminal across the notch of the terminal block and the terminal groove of the guide plate, and fix the terminal groove at the specified position of the lead terminal. For example, the lead terminal is clamped and fixed at the intersection of the notch and the terminal groove. Therefore, select the end of the notch and the terminal groove as a crossing point at a predetermined position of the lead terminal, narrow it down to a diameter slightly larger than the thickness of the lead terminal, and make the other parts of the notch and the terminal groove sufficiently wider than the thickness of the lead terminal. If selected, the lead terminal can be inserted and fixed in a very simple manner without bending or scratching the lead terminal and without the need for adhesive work.

〔Example〕

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an exploded perspective view of a case with a terminal block for electronic parts having windings according to an embodiment of the present invention. That is, the winding 6 is applied to the ring case 4 in which the ring core (not shown) is covered and insulated, and the lead terminal 3 is formed by extending the tip end of the winding 6. A terminal block 1 connected by columns 7 is integrally provided at a lower portion of the ring case 4, and a wide opening toward the inside is formed at a predetermined position of the lead terminal 3 on two opposite sides of the terminal block 1, and a terminal end is a lead. A notch 2 narrowed to a diameter slightly larger than the diameter of the terminal 3 and an L-shaped guide 5 are formed on the bottom surface. Separately from this, there is prepared a slide plate 8 having a wide opening to be inserted into the guide 5 and having a hook-shaped terminal groove 9 whose end is narrowed down to a diameter slightly larger than that of the lead terminal. The case is made up. The lead terminal 3 is fixed to the predetermined position in the case with the terminal block for electronic parts configured as described above in the following manner.

FIG. 2 (a) is a bottom plan view of the case with electronic component terminal block in a state immediately before inserting the slide plate into the terminal block in FIG. 1 and fixing the lead wire at a predetermined position. That is, the slide plate 8 is inserted into the L-shaped guide 5 provided on the bottom surface of the terminal block 1, and the notch 2 of the terminal block 1 and the terminal groove 9 of the slide plate 8 are inserted.
The lead terminals 3 are inserted all the way along the sides of the.

If the slide plate 8 is further integrally inserted in the direction of the arrow 10 in this state, the lead terminal is inserted into the hook portion 16 of the hook-shaped terminal groove 9 and, as shown in FIG. The lead terminal 3 is fixed to a predetermined position of the closed space surrounded by the notch 2 provided in the above and the hook 16 of the terminal groove 9 provided in the slide plate 8 intersecting with the notch 2. In this case, cutout 2
The terminal groove 9 has a wide opening width, and a predetermined portion for fixing the lead terminal 3 at the end is narrowed to a diameter slightly larger than the thickness of the lead terminal 3. Therefore, in the work of inserting and fixing the lead terminal 3, the work can be performed easily and in a short time without bending or scratching the lead terminal 3. Further, the fixed portion of the lead terminal 3 is a closed space where the notch 2 and the hook portion 16 of the terminal groove 9 intersect with each other.
Since it is fixed by being surrounded by this closed space, it is not necessary to fix it with an adhesive or the like.

Although the guide 5 is L-shaped in the example of the present invention, it may be a slide-type guide having a combination of a wedge-shaped convex portion and a concave portion. Further, although the terminal groove 9 has a hook shape, it may be a linear type terminal groove in which two sides of the slide plate 8 are obliquely formed.

C. Effect of the Invention [Effect of the Invention] As described above, according to the present invention, when fixing the lead terminal of the electronic component to the terminal block, the lead terminal is not bent or flawed, and the work is performed. It is possible to provide a case with an electronic component terminal block that is simple, saves work time, has good electronic component quality, and can be manufactured at low cost.
