Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a connector suitably used as a terminal connector for a computer, for example.

BACKGROUND ART As shown in FIG. 4, this type of general connector includes an insulating insert 102 in which a plurality of through holes 101 are formed in a row at regular intervals, and a female mold is inserted into each through hole 101 of the insulating insert 102. It has a structure in which contacts 103 are press-fitted. And this female contact 1
As shown in FIG. 5, the parts 03 are made by punching out hoop material and are integrally connected by a connecting part 104.

However, the connector having such a structure has the following problem when the pitch interval P of the female contacts 103 is small.

Problem to be solved by the invention Now, the pitch interval P of the female contact 103 is
Taking the case of a 2.76mm standard product as an example,
In that case, the width W of the female contact 103 is:
Due to the diameter of the mating male contact and restrictions on punching, it has to be set to about 2.4 mm. Section 1031
The mutual spacing C ₃ is only about 0.36 mm, and the female contact 103 is connected to the connecting part 104 by punching.
This makes it impossible to build them in a connected state. Therefore, as shown by the broken line in Figure 5,
It is not possible to reduce the mutual spacing C ₃ between adjacent female contacts 103 to about 0.36 mm, and as shown by the solid line, the mutual spacing C ₄ has to be increased to at least about 0.5 mm, which is sufficient for punching. It was.

However, if the mutual spacing C ₄ of the female contacts is large, as shown in FIG.
04, it is impossible to press fit each female contact 103 into each through hole 101 of insert 102 at once. Connectors were manufactured by press-fitting them one by one. Therefore, in the past, the manufacturing efficiency of the connector was low, and since the corner portions 1031 of adjacent female contacts 103 were close to each other, there was a problem in terms of withstand voltage.

Means for Solving the Problem In order to solve the above problem, the present invention press-fits a female contact into each through hole of an insulating insert in which a plurality of through holes are formed in a row at regular intervals. The main feature of this connector is that the corners of adjacent female contacts, which act as detents, are positioned at different levels.

Effect of the device In this way, when the corners of adjacent female contacts are positioned in a stepped manner, the mutual spacing between the female contacts becomes large (for example, the pitch spacing of the female contacts is 2.76 mm as described above). Even if it is as small as 0.5mm, the distance between the corners of adjacent female contacts is 0.5mm.
(the above can be made), it is possible to punch and form the female contacts while connected to the connecting part, and it is possible to press fit each female contact into each through hole of the insert at once in that state. becomes. Moreover, when the mutual distance between the corner portions of adjacent female contacts is large, the withstand voltage is also increased, and reliability is further improved.

Example Hereinafter, the present invention will be described in detail with reference to Examples.

FIG. 1 is a sectional view showing a connector according to an embodiment of the present invention, in which 2 is an insulating insert made of synthetic resin or the like, and this insert 2 has a plurality of through holes 1 arranged at predetermined intervals. They are formed in rows with spaces between them. A female contact 3 is press-fitted into each through-hole 1, and is inserted so that it will not come off easily by corner portions 31 and 31' serving as left and right detents.

As shown in FIG. 2, these female contacts 3 are made into an asymmetrical shape by cutting off a portion 32 corresponding to a part of the corner 1031 of the conventional example shown by a broken line, and the left and right corners 31 serve as detents. , 31' are arranged at different levels. In this way, when the left and right corners 31, 31' are stepped, even if the pitch interval P of the female contacts 3 is small as in the conventional example, the mutual interval between adjacent female contacts
In other words, the distance C ₁ from the lower corner 31 of one female contact to the other adjacent female contact,
and the distance _C2 from one female contact to the upper corner 31' of the other adjacent female contact,
Both are larger than the conventional mutual spacing _C3 . Therefore, as shown in FIG. 2, even if the pitch interval P of the female contacts is made smaller in accordance with the interval between the through holes 1 of the insert 2, each female contact 3 is connected integrally to the connecting part 4. It is now possible to punch out the hoop material, and while in this connected state, each female contact 3 can be press-fitted into each through hole 1 of the insert 2 at once, and then each female contact 3 can be separated from the connecting part 4. This makes it possible to significantly improve manufacturing efficiency. Moreover, as mentioned above, the mutual spacing C ₁ , C ₂ between adjacent female contacts
When is large, the withstand voltage becomes high and the reliability also improves.

FIG. 3 is a sectional view showing another embodiment of the present invention, in which female contacts 3a and 3b of different shapes are alternately press-fitted into each through hole 1 of the insert 2. That is, these female contacts 3a and 3b are both symmetrical, but one female contact 3a has a height from the upper end to the left and right corners 31, similar to the conventional female contact. is set large, whereas the other female contact 3b has a large width at the left and right corners 31' from the top end.
The height to the corner portions 31, 3 of the adjacent female contacts 3a, 3b is set small.
1' are arranged in different steps.
Even with this configuration, the same effects as described above can be obtained.

Effects of the invention As can be understood from the above explanation, according to the invention, even if the pitch spacing of the female contacts is small, the mutual spacing between the female contacts can be set large, so the female contacts are integrated at the connecting part. It is now possible to punch out a hoop material while connected to the hoop and press-fit it all at once into the through hole of the body, which greatly improves manufacturing efficiency, increases the withstand voltage, and improves reliability. The effect of this can be obtained.
