Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to terminals of coil bobbins such as surface mount type transformers and choke coils.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 2, in FIG. 2A, one S-shaped terminal 3 which is a modification of the coil bobbin 1 is attached to a terminal block 2 and a fine wire 4 is wound. In (b), the rod-shaped terminal 3 is provided on the terminal block 2 of the coil bobbin 1, and the ultrafine wire 4 is wound. The terminal 3 of this type of coil bobbin 1 has a drawback that the wire 4 of an ultrafine wire is entangled, soldered, and then cut by deflection of the terminal such as pressure. Also, in order to prevent disconnection, there was a structure in which the terminal and the coil bobbin were twisted into a figure 8, and measures were taken to lift the coil bobbin at the root of the terminal to twist it, but it is weak against lateral pressure. There was a drawback. There was also the drawback that the thin wires twisted on the terminal block would soon come apart.

[0003]

[Problems to be solved by the device]

 In order to eliminate these drawbacks, the present invention is provided with a plurality of Z-shaped terminals at the top and bottom of the terminal block, which is the place where the bobbin is twisted. The purpose is not to be cut and to be cut.

[0004]

[Means for Solving the Problems]

 That is, the present invention is a coil bobbin used for a transformer or a choke coil mounted on a printed circuit board. When an ultrafine wire is used, an even number of plate-shaped Z-shaped terminals with a rectangular cross section are placed on the prismatic terminal block of the coil bobbin. It is an extra-fine wire cord terminal that is symmetrically provided on the horizontal axis.

[0005]

According to the present invention, in addition to a Z-shaped terminal having a rectangular cross section, a plurality of Z-shaped terminals having a rectangular cross section are vertically arranged symmetrically with respect to the horizontal axis in order to reinforce the barb. The feature is that even if pressure is applied to the top, bottom, left and right, the wire will not come apart and will not be easily cut. That is, a thin wire is wound between two upper and lower Z-shaped terminals in an eight shape, and the two terminals are arranged so as to be symmetrical about the Z shape in the horizontal direction. The thin line never derails. Next, the thin wires applied to the terminal block are routed between the terminals, so there is no derailment from here. In addition, the thin wire is placed so that it fills up completely between the two terminals and fills the two terminals, so the two terminals do not bend when pressure is applied to the upper and lower terminals, and the wire breaks. Is to prevent.

【Example】

 FIG. 1 is a perspective view of an extra-fine wire entanglement terminal according to an embodiment of the present invention. FIG. 2 is a perspective view of an extra-fine wire-pulling terminal of a conventional example. In FIG. 2, a single S-shaped terminal 3 is provided on a terminal block 2 attached to a coil bobbin 1, and as shown in FIG. 2 (a), a substantially fine wire 4 is wound around the S-shaped terminal. It can also be twisted on the terminal block. In the case of thin wires, the number of turns of the extra-fine wire is large due to soldering or disconnection, and it may cause the cutting, loosening, slacking, and disconnection of the extra-fine wire due to the bending of the terminal block (a) or the S-shaped terminal Was becoming. As shown in (b), the same applies to the wire 4 of the winding wound around the rod-shaped terminal 3 planted in the terminal base 2 provided on the coil bobbin 1. FIG. 1 describes a substantially Z-shaped barb terminal and a bark-reinforced terminal provided with two substantially Z-shaped terminals on the terminal block 2 attached to the coil bobbin 1. First, two substantially Z-shaped terminals are implanted in the terminal block 2 so as to be symmetrical in the lateral direction. The upper substantially Z-shaped terminal is the barbed terminal 5. The lower, substantially Z-shaped terminal is an extra-fine wire-barrel reinforcing terminal 51, which is symmetrically planted with the upper barb terminal. That is, the direction is reversed. The ultrafine wire 4 is wound between the barbed terminal of the substantially Z-shaped terminal 5 of FIG. 1 and the barbed reinforcing terminal 51 of the ultrafine wire so as to draw a figure of 8, and the winding of the lead wire is further performed. An extra fine wire 4 is also wound on the terminal block 2 between the wire, that is, between a barbed terminal 5 of a substantially Z-shaped terminal and a barbed reinforcing terminal 51 of an ultrafine wire. As long as the wire 4 of the thin wire provided with two thin Z-shaped terminals does not cross the board mounting surface 6 of the terminal, which is attached to the printed circuit board, that is, the Z-shaped terminal Z As long as it does not cross the hook-shaped corner, the ultrafine wire will not slacken, will not derail, and will not come apart. Further, the ultrafine wire 4 wound on the terminal block 2 is also caught between the two substantially Z-shaped terminals and cannot be derailed. As a result, cutting, loosening, derailment, and loosening of the ultrafine wire 4 applied to the terminal block 2 do not occur. Also, the wire between the caulking terminals, which are the two substantially Z-shaped terminals, and the caulking reinforcing terminal of the ultrafine wire is completely filled with the wire 4 of the ultrafine wire. The gap between the two substantially Z-shaped terminals is filled with the wire 4, and the movement of the terminals is stopped. In the regular winding, the gap between the two substantially Z-shaped terminals is filled in tightly. This stops the movement of arrow 7 and prevents disconnection.

[Effect of the device]

 As described above, according to the present invention, by entwining a fine wire with a sled terminal, a slender reinforcing terminal of the ultrafine wire, and a terminal block of the bobbin in a slalom shape, the terminal can be pressed up, down, left, or right. It is now possible to provide a fine wire twisting terminal of a coil bobbin that makes it difficult for wires to come loose, loosen, derail, or be cut even when a force is applied.
