Abstract

PURPOSE:To prevent an electrical part from increasing in size due to the increasing number of signals to be transmitted by a method wherein two kinds of signals in an electrical part are transmitted by one contact pin. CONSTITUTION:Among conductors 2, 4 and an insulator 3, a connecting terminal 41 of the conductor 1 is fitted into a hollow of the insulator 3 and the insulator a is fitted into a hollow of the conductor 1 so as to constitute a contact pin. The conductors 2, 4 are thus electrically insulated by the insulator 3. This enables a signal of a line 6 in an electrical part to be transmitted to a substrate line 13 and a signal in a line 5 in the electrical part to be transmitted to a substrate line 14 simultaneously. Two kinds of signals can be thus transmitted by one contact pin so that increase in size of the electrical part can be avoided even if the number of signals to be transmitted increases.

Description

DETAILED DESCRIPTION OF THE INVENTION ±Blood 1 The present invention relates to a connection pin, and particularly to a connection pin provided on an electric component such as an IC.

Previously, this type of connection pin was made of a conductor-only material, and after being inserted into a hole in a board, etc., the connection was made by soldering or crimping.

This conventional connection pin has the disadvantage that only one signal can be transmitted per pin, so as the number of signals to be transmitted increases, the number of pins increases accordingly and the size of the electrical components increases. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a connecting pin that does not require an increase in the size of electrical components even when the number of signals to be transmitted increases.

The connecting pin of the present invention is a connecting pin that is provided on a component to be mounted on a board and inserted into a hole for mounting the component on the board, and the connecting pin is connected to an insulator member and the insulator. A plurality of conductor members are electrically insulated by the members.

K 1 Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is an external view of a connecting pin according to an embodiment of the present invention. In FIG. 0, a connecting pin 1 according to an embodiment of the present invention is
Connection ends 21 and 41, fixed ring part 22, and insulation fI
M31, and is provided on an electrical component (not shown).

Next, the internal structure of the connecting pin 1 will be explained using FIG. 2. FIG. 2 is an exploded view of the connecting pin of this embodiment. As shown in FIG. 0, the connecting pin of this embodiment is composed of three parts, namely 2.3 and 4.

Of these, 2 and 4 are made of a conductor, and 3 is made of an insulator.

The conductor 2 has a configuration in which a connecting end 21 and a fixing ring portion 22 are provided in a hollow cylinder.

The insulator 3 has a structure in which an insulation @31 is provided in a hollow cylinder.

The conductor 4 has a cylindrical structure with a connecting end 41 provided therein.

As described above, among the conductors 2 and 4 and the insulator 3, the connection end 41 of the conductor 4 is fitted into the hollow part of the insulator 3, and the insulator 3 is fitted into the hollow part of the conductor 2, so that the connection end 41 of the conductor 4 is fitted into the hollow part of the insulator 3. The connecting pin 1 shown in FIG. 1 is constructed. In other words, the conductors 2 and 4 are electrically insulated by the insulator 3.

Next, a case where the connection pin of this embodiment is used in an electrical component will be explained using FIG. FIG. 3 is a cross-sectional view showing the structure when the connecting pin of this embodiment is used in an electrical component. Parts equivalent to those in FIGS. 1 and 2 are designated by the same reference numerals. This electrical component 15 has connection ends 21 and 41 of the connection pins of this embodiment.
is buried. Further, after this connecting pin is inserted into the hole of the board 10 in the direction of arrow A, the conductor 2 and the board wiring 13 are connected by the solder 11, and the conductor 4 and the board wiring 14 are connected by the solder 12. It is something that

On the other hand, the connection end 21 of the connection pin is connected to the electrical component wiring 6 in advance, and the connection @41 is connected to the electrical component wiring 5 in advance. Further, the fixing ring part 22 of the connecting pin keeps the position of the connecting pin and the hole of the board 10 constant to prevent the conductor 2 and the board wiring 14 from being connected, and also prevents the board wiring 14 from being connected.
This is provided to increase the contact area to ensure a reliable connection. Furthermore, the insulated end 31 is connected to the conductors 2 and 4.
Since the diameter is larger, it is possible to prevent erroneous connections due to solder 11 or 12.

According to this configuration, the signal of the electrical component wiring 6 can be transmitted to the board wiring 13, and at the same time, the signal of the electrical component wiring 5 can be transmitted to the board wiring 13.
This means that the signal can be transmitted to the board wiring 14. Therefore, since two types of signals can be transmitted using one connection pin, even if the number of signals to be transmitted increases, there is no need to increase the size of the electrical components.

In addition, although the case where the shape of the connection pin is cylindrical has been described in this embodiment, other shapes, such as a square prism, may be used.
It is not limited to that.

Further, in this embodiment, two types of signals are transmitted using one connection pin, but it is clear that three types of signals can be transmitted using one connection pin.

In this case, the conductor may have a three-layer structure, and an insulating layer may be provided between each conductor.

As explained above, the present invention transmits two types of signals in an electrical component using one connection pin, so that even if the number of signals to be transmitted increases, the size of the electrical component can be increased. The effect is that you don't have to do it.
