Technical field to which the present invention pertains Prior art (FIGS. 5 to 6) Problems to be Solved by the Invention Means for Solving the Problems Embodiments of the Invention (FIGS. 1 to 4) Effects of the Invention

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly, to a connector suitable for application to a connector for mounting a printed circuit board, in which a plurality of connection terminals are arranged in a predetermined pitch.

[0003]

2. Description of the Related Art Conventionally, there is a connector of this type, for example, as shown in FIG. This connector 1 is shown in FIG.
As shown in FIG. 6A and FIG. 6B, the first connection portion 2 and the second connection portion 3 made of phosphor bronze, each having a substantially “Y” -shaped cross section, are connected to the first connection portion. A predetermined number of alternately press-fitted housing portions 4 of insulating material molded according to the shapes of the first connection portion 2 and the second connection portion 3 and provided on the front surface of the housing portion 4 for inserting a flexible wire. The part 5 includes first connection terminals 2A and 3A provided in the first connection part 2 and the second connection part 3, respectively.
It is configured to be exposed by pitches P having an arrangement of 0.5 [mm].

[0004] As shown in FIG.
Has a first fitting portion 2B and a second fitting portion 2C, and the first and second fitting portions 2B and 2C
Is held in the housing portion 4 by being press-fitted into the housing. A first connection terminal 2A is provided between the first fitting portion 2B and the second fitting portion 2C of the first connection portion 2 so as to face diagonally upward. As shown in FIG. 5, each first connection terminal 2A is
When each of the first connection terminals 2A
Is positioned in the corresponding groove 5A provided in the opening 5.

The tip 2AX of the first connection terminal 2A is formed in a convex shape, and the first connection terminal 2A is
When the connection portion 2 is press-fitted into the housing portion 4, the distal end portion 2AX of each first connection terminal 2A is formed to protrude from the corresponding groove 5A. As a result, when a flexible wire (not shown) is inserted into the opening 5, the distal end portion 2AX of the first connection terminal 2A is pressed by the flexible wire in the direction indicated by the arrow a in the drawing, whereby each first wire is pressed. 1
The connection terminal 2A and the corresponding flexible wire can be surely brought into contact with each other.

[0006] Similarly, as shown in FIG. 6B, the second connecting portion 3 has a first fitting portion 3B and a second fitting portion 3C. The parts 3B and 3C are held by the housing part 4 by being press-fitted into the housing part 4. In addition, the first of the second connecting portions 3
A first connection terminal 3A is provided between the fitting portion 3B and the second fitting portion 3C. As shown in FIG. 5, the first connection terminals 3 </ b> A are provided in the openings 5 according to the respective first connection terminals 2 </ b> A when the second connection portions 3 are press-fitted into the housing portion 4. Is positioned in the groove 5A.

Further, the tip 3AX of each first connection terminal 3A
Is formed in a convex shape, and each first connection terminal 3AX is
When the second connection part 3 is press-fitted into the housing part 4,
Of the connection terminal 3A is formed so as to protrude from the groove 5A. As a result, when the flexible wire is inserted into the opening 5, the distal end portion 3AX of each first connection terminal 3A is pressed by the flexible wire in the direction indicated by the arrow a in the figure, whereby each first connection terminal 3A is pressed. 3A and the flexible wire can be surely brought into contact with each other.

Here, the first connection terminal 2 of the first connection portion 2
A and the first connection terminal 3A of the second connection portion 3 have different lengths. That is, from the back surface 2D of each first connection part 2,
The length L1 of the connection terminal 2A to the tip 2AX is 2.9
[Mm], and the length L2 from the back surface 3D of each second connection portion 3 to the tip 3AX of each first connection terminal 3A is:
2.7 [mm] is selected. Accordingly, when each of the first connection portions 2 and each of the second connection portions 3 are press-fitted into the housing portion 4,
Since the lengths of the first connection terminal 2A and the first connection terminal 3A are different, the end of the first connection terminal 2A and the end of the second connection terminal 3A are arranged in a zigzag shape. .

The lower ends of the back surfaces 2D and 3D of the first connecting portions 2 and the second connecting portions 3 have second connecting terminals opposite to the first connecting terminals 2A and 3A, respectively. 2
E and 3E are provided. These second connection terminals 2
When the connector 1 is mounted on the printed circuit board 6, E and 3E can make contact with corresponding wiring (not shown) formed on the printed circuit board 6.

Thus, in the connector 1, when the flexible wire is inserted into the opening 4, the first connection terminal 2A of each first connection portion 2 and the first connection terminal 3A of each second connection portion 3 are connected. Connected to a corresponding flexible wire so that the flexible wire can be electrically connected to the printed circuit board 6 via the second connection terminals 2E and 3E of the first and second connection portions 2 and 3, respectively. It has been done.

[0011]

However, since the pitch P between the adjacent connection terminals 2A and 3A is as small as 0.5 [mm], a contact probe (not shown) is brought into contact with the first connection terminal 2A or 3A. In this case, it has been extremely difficult to stably conduct the continuity measurement work, for example, care must be taken so that the probe does not contact the adjacent first connection terminal 3A or 2A.

Further, since the pitch P between the adjacent connection terminals 2A and 3A is 0.5 [mm], the thickness of the contact probe must be formed to be less than 0.5 [mm]. However, when the thickness of each probe is less than 0.5 mm, the durability of the probe is weakened, and the probe may be damaged during the continuity measurement. There was a possibility that the reliability of the device was reduced.

As one method for solving such a problem, a pitch P between adjacent connection terminals 2A and 3A is used.
Can be considered. However, when the pitch P between the adjacent connection terminals 2A and 3A is widened, that is, when the arrangement pitch between the first connection portion 2 and the second connection portion 3 is widened,
Since the entire connector 1 is increased in size, there is a problem that it is impossible to cope with downsizing and higher density of electronic devices.

Although it is conceivable to conduct a continuity measurement by inserting a flexible wire directly into the opening 4 of the connector 1, the durability of the flexible wire is insufficient for conducting the continuity measurement, and the flexible wire is damaged. There was a fear. Furthermore, the insertion of a flexible wire into the opening 4 of the connector 1 to perform the continuity measurement has a problem that it greatly restricts the automation of the continuity measurement operation. At the same time, since the flexible wire is very thin, the wiring may be broken in the middle, and the reliability of the measurement result obtained by conducting the continuity measurement is insufficient.

The present invention has been made in view of the above points, and it is an object of the present invention to propose a connector capable of stably and easily measuring the continuity of a printed circuit board.

[0016]

SUMMARY OF THE INVENTION In order to solve this problem, according to the present invention, a holding portion for integrally holding a plurality of connection terminals arranged in a predetermined first pitch is wider than the first pitch. A plurality of conductive portions are provided so as to be connected to corresponding connection terminals so as to be exposed to the outside by the second pitch. According to the present invention, when conducting continuity of a printed circuit board, each conducting portion can be used instead of each connection terminal.
