Description

[Detailed Description of the Invention] The present invention relates to a clamper for bundling wires and fixing them on the surface of a printed circuit board.

When a complex circuit is constructed using a small printed circuit board, the printed parts alone are not enough to connect each component of the circuit, and a large number of wires may be attached to the printed circuit board for connection. In this case, these wires float on the printed circuit board, making the assembled printed circuit board bulky and difficult to handle. For this reason, in the past, for example, as described in the specification of Utility Model Application No. 136906/1980, a protruding part is processed on the board, and the protruding part and the wire are tied together with a binding tool to hold and fix the wire to the board. There is technology. With this conventional technique, the position for holding and fixing cannot be set freely, and the position is determined when the board is created, and the position, quantity, mounting interval, etc. cannot be changed. Furthermore, serious problems remain, such as the processing of the board reduces the packaging density of the board.

The present invention was proposed in view of these points, and it eliminates the above-mentioned problems, allows wires to be bundled well, and furthermore, when the bundled wires are fixed to a printed circuit board, the mounting density of the printed circuit board is not affected. Furthermore, the present invention provides a clamper that does not require additional processing of printed circuit boards.

The present invention will be explained below with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of the present invention, and FIG. 2 is a perspective view showing a specific usage example of the same embodiment.

In the figure, reference numeral 1 denotes a clamper, and one end thereof forms a ring-shaped body 2 that can be elastically opened and closed to bundle the wire rods 4 when the wire rods 4 are inserted thereinto. The other end constitutes a locking portion 3 that is hooked onto a lead terminal 13 of a resistor 12 soldered to a printed circuit board 3, for example.
That is, this clamper 1 holds the wire 4 at a predetermined distance from the printed circuit board. This clamper 1
is made of an insulating and elastic material such as synthetic resin, and the ring-shaped body 2 has its free end 2' expanded by utilizing its elasticity so that the wire 4 can be inserted therethrough.
The locking part 3 is locked to the lead terminal 13, and when the wire 4 is inserted through the ring-shaped body 2, the tension of the ring-shaped body 2 causes the locking part 3 to be pulled in the direction of the wire 4.
It is held so that it cannot be pulled out. In addition, when the locking part 3 is hooked on the lead terminal 13, the lead terminal 1
3 is attached to the locking part 3 to prevent it from being pulled out from the locking part 3.
A raised portion 14 as shown by the dotted line in the figure may also be provided.

Further, FIG. 3 is a perspective view showing another embodiment, and FIG.
The figure is a bottom view of the same embodiment, and FIG. 5 is a perspective view showing a specific usage example of the same embodiment.

Reference numeral 5 in FIG. 3 corresponds to the annular body 2 of the above-described embodiment, and 7 corresponds to a locking portion. In this embodiment, when the wire 4 is inserted into the annular body 5, the wire 4 is biased to be gripped and the wire 5 is bundled as in the previous embodiment. Further, by sliding the locking portion 7 along the surface of the printed circuit board 3 from the lead terminal 13 side of the resistor 12, the lead terminal 13 is inserted into the groove through the insertion groove 8 provided in the locking portion 7. One side insertion groove 8
A pair of protrusions 6 are provided inside facing each other, and the lead terminal 13 of the resistor 12 inserted into the insertion groove 8 rides over the pair of protrusions 6 and is locked, thereby fixing the clamper 9 to the printed circuit board 3. do. The insertion groove 8 has a width into which the resistor 12 is fitted.

In the case of FIG. 3, one end of the locking part 7 is fitted to the resistor 12, but at least one end of the locking part 7 is fitted to the lead terminal 13.
It is fine as long as it can be locked to.

As described above, according to the present invention, the wires floating on the printed circuit board can be bundled, and the bundled wires can be attached to the electronic components mounted on the printed circuit board. It is effective because it can reduce the bulk. Furthermore, by attaching to the lead terminals of electronic components, the mounting density on the printed circuit board is not reduced, there is no need to process new printed circuit boards, and the mounting position and number of clampers can be changed relatively freely as necessary. This has a practical effect.
