Between the pair of first and second guide plates 5 and 7 facing each other in a substantially inverted V shape, a substantially V-shaped guide portion 14 having a lower portion separated is formed. Therefore, the guide portion has a substantially wavy shape as a whole.

Further, the contact insertion jig 1 is mounted on the first plate portion 5 located on one end side of the pair of first and second plate portions 5 and 7 formed continuously. The second additional plate portion 7 ′ facing each other and the second additional plate portion 7 ′ located on the other end side
And a first additional plate portion 5 ′ facing the plate portion 7 of FIG.

That is, in this embodiment of the contact insertion jig 1, the space portions of a plurality of pairs of the first and second plate portions 5 and 7 formed continuously, the first end portion on the one end side are formed. Board 5
The space portion of the second additional plate portion 7 ′ and the space portions of the second plate portion 7 and the first additional plate portion 5 ′ on the other end side serve as guide portions 14.

It is formed at a distance of twice or more. In addition,
In the example of the embodiment shown in FIG.
The distance P1 (pitch) between the center lines X1 and X1 of the two is set to be twice the distance P2 (pitch) between the center lines X2 and X2 of the adjacent insertion holes 12.

Next, a method of manufacturing a connector using the above-mentioned contact insertion jig 1 will be described.

First, the contact insertion jig 1 faces the insertion holes 12 and the lower guide ports 1 of the guide portions 14.
Position 8. This allows the plurality of contacts 20
While being guided, they are inserted one by one into the insertion holes 12.

When the contact 20 is temporarily inserted into the insulator 10, the insertion hole 12 and the contact portion 20b of the contact 20 are accurately aligned and inserted. Therefore, a tapered guide port 12a is formed from the rear surface of the insulator 10 to the insertion hole 12. When the tip of the contact part 20b enters the upper guide port 16, it can be inserted into the insertion hole 12 while being guided by the tapered surface of the guide part 14 even if there is a large deviation from the lower guide port 18. The lower guide port 18 of the guide portion 14 is installed so as to coincide with the guide port 12 of the insulator 10.

[0033]

As described above with reference to the embodiments, according to the contact insertion jig of the present invention, the upper portion of the guide portion is an upper guide port which is considerably larger than the guide port of the insulator. Even if the contact pitch is narrow, the contact portion of the contact can be reliably inserted into the insertion hole even if the contact is roughly inserted.

Further, since each of the guide portions is opposed to every other insertion hole of the insulator, the contact portion of the contact is temporarily inserted into the insertion hole of the insulator in the first step. Then, after shifting the contact insertion jig in the direction parallel to the rear surface of the insulator with the pitch of one insertion hole, and temporarily inserting the contact part of the contact as the second step, the contact is surely inserted into all the insertion holes of the insulator. it can.

Therefore, it is possible to provide a contact insertion jig which can improve the temporary insertion property, can make the positioning accuracy and the component accuracy rough, and can improve the productivity of the electrical connector.
