Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method of manufacturing a connector for electrically connecting devices of various electronic devices, and in particular, the present invention relates to a method of manufacturing a connector for electrically connecting devices of various electronic devices, and in particular, twisting a part of the contact to insulate the contact. The present invention relates to a method of manufacturing a connector configured to be fixed to a body.

In manufacturing connectors in which multiple plate-shaped contacts made of brass strips, phosphor bronze strips, etc. are inserted into square holes provided in an insulator, after the contacts are inserted into the insulator, the roots are twisted and the insulation is removed. Methods to prevent them from falling off the body are widely used.

No matter how the number of plate contacts increases in the manufacture of such connectors, there is a need for a method that can reliably fix the contacts to an insulator with good workability.

[Conventional technology]

FIG. 2 shows an example of a conventional manufacturing method. FIG. 2a is a plan view showing the shape of a plate-shaped contact, and FIG. 2b is a perspective view showing a method of twisting the base of the contact.

The contact 1 made of brass, phosphor bronze, etc. has a stopper 2, and also has a stopper 2 to facilitate twisting.
Notches 3 and 4 are provided at locations to form claws 5. The contact 1 is inserted into the square hole 7 provided in the insulator 6, and then a punch 8 and a die 9, each having a pressing slope at the tip and pressing the claw 5 from above and below, are inserted.
The contact 1 is inserted by sewing the gap between the contacts 1 inserted around the periphery, changing the angle of the claw 5, and locking the contact 1 to the insulator 6.

[Problem that the invention seeks to solve]

In the conventional manufacturing method, if the number of rows of contacts 1 is about two, punches 8 and dies 9 are arranged one above the other, and sufficient twisting can be performed from the right angle direction of the contacts 1.

However, when the number of rows of contacts 1 increases and the upper and lower contacts 1 overlap, there is no longer a gap for inserting the punch 8 and die 9, causing problems such as making twisting impossible.

[Means for solving problems]

The problem described above is that the contact is inserted into the insulator until the first notch of at least two notches forming claws in the plate contact is exposed from the insulator. After inserting a twisting tool from the direction to apply a predetermined twist and then further inserting the contact until the second notch is exposed from the insulator, the surfaces of the plate-shaped contact exposed on both sides of the insulator By twisting the twisting tool inserted into the contact in the opposite direction so that they form the same plane, the claw formed by the notch is twisted so as to form an arbitrary angle with respect to the surface of the plate-shaped contact. This problem is solved by the method of manufacturing a connector according to the present invention.

[Effect]

A two-step process in which twisting is applied at the point where the first notch 3 is exposed from the insulator 6, and untwisting is performed at the point where the second notch 4 is exposed from the insulator 6, allows the insulator to be exposed on both sides. At the same time, the surfaces of the plate-like contacts formed on the same plane form the same plane, and at the same time, the angle of the claw 5 sandwiched between the notches 3 and 4 can be changed, and the angle of the claw 5 can be changed depending on the number of rows of contacts 1. It is possible to insert the twisting tool from the axial direction and perform processing.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.
Note that the same objects as in FIG. 2 are represented by the same symbols. FIG. 1 is a perspective view showing a method of manufacturing a connector according to the present invention, and FIG. 1a is an example of a twisting tool;
Figures b to 1e show the manufacturing process.

As shown in FIG. 1a, the twisting tool 10 has a groove 12 at one end of a shaft 11 into which the contact 1 is inserted, and a grip 13 at the other end.

To manufacture a connector using such a twisting tool, as shown in FIG. 1b, the contact 1 is inserted into the square hole 7 until the first notch 3 is exposed from the insulator 6,
As shown in Figure c, the groove 12 of the twisting tool 10 is inserted into the contact 1 from the axial direction to apply a predetermined twist.

Next, as shown in FIG. 1d, contact 1 is connected to the second
Further insert the plate contact 1 until the notch 4 of the insulator 6 is exposed from the insulator 6, and as shown in FIG. Twist the twisting tool 10 inserted into the contact in the opposite direction.

Twisting is applied at the point where the first notch 3 is exposed from the insulator 6, and the second notch 4 is exposed from the insulator 6.
A two-step process in which the exposed point is twisted in the opposite direction,
The twist in the first notch 3 is slightly restored, but since that part is plastically deformed, not all of the twist is restored, and the second notch 4 is twisted in the opposite direction. arise.

Therefore, after twisting the notch 3 part, the notch 4
By twisting the part in the opposite direction, the surfaces of the plate contact exposed on both sides of the insulator form the same plane, and the claw 5 forms an arbitrary angle with the surface of the plate contact. is given a twist.

Furthermore, by inserting the twisting jig 10 from the axial direction of the contacts 1, it is possible to securely fix the contacts 1 to the insulator with good workability, regardless of the number of rows of the contacts 1.

〔Effect of the invention〕

As described above, according to the present invention, contacts can be securely fixed to an insulator with good workability regardless of the number of rows of contacts.
