Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a jack, and particularly relates to an improvement of the contact terminal thereof.

(Prior Art) In a conventional jack, the contact terminal 1 is formed by punching out a metal plate so that the spring contact part 11 and the terminal leg part 12 form an L-shape from the beginning, as shown in FIG. Was. However, this method of forming the contact terminal 1 has the drawback that a large amount of material is wasted, resulting in high costs.

(Purpose of the invention) An object of the invention is to provide a jack which is equipped with a contact terminal having a structure that can be formed without wasting material and which can reduce costs.

(Structure of the invention) In the present invention, a contact terminal is incorporated in a jack housing, and the contact terminal is a stamped and molded product of a metal plate, and the spring contact part and the terminal leg part form an L-shape. In the jack, the contact terminal has a shape in which the spring contact portion and the terminal leg portion are parallel when unfolded into a flat plate shape, and are connected to each other by a connecting piece portion in a direction that intersects with each other; The contact terminal is characterized in that it is formed into a substantially L-shape by bending at the connecting piece.

In this way, the contact terminal of the jack of the present invention has a shape in which the spring contact part and the terminal leg part are connected by the connecting piece part in the direction that intersects with each other when it is unfolded in a flat state. Since the contact portion and the terminal leg portion are oriented parallel to each other, the jack can be manufactured without wasting material, and as a result, the cost of the jack can be reduced.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings. First, the structure of the contact terminal 1 used in the jack of the present invention will be explained.

FIG. 2 is a plan view for explaining the unfolded state of the contact terminal 1, which forms the main part of the jack of the present invention. This contact terminal 1, in the unfolded state,
The spring contact part 11 and the terminal leg part 12 are parallel to each other, and the connecting piece part 1 is oriented so that they intersect with each other.
It has a shape that is connected by 3. Therefore, in this state, the spring contact portion 11 and the terminal leg portion 12 are oriented parallel to each other, and can be punched and formed without wasting material.

In addition, in FIG. 2, 21, 22, and 23 are bending lines added for ease of explanation.

FIG. 3 is for explaining the bending state of the contact terminal 1 used in the present invention at the bending lines 21, 22, and 23, and all plate thicknesses are omitted.
The contact terminal 1 shown in FIG.
At the bending line 22, the connecting piece 13 is bent in a direction perpendicular to the spring contact part 11, and at the bending line 22, the connecting piece 13 is bent at right angles in a direction in which the part adjacent to the terminal leg 12 is separated from the spring contact part 11. Bend the terminal leg 12 to the spring contact part 1 at the bending line 23.
It is bent at right angles so as to be lined up in one plane with 1, so that the entire shape is approximately L-shaped.

The contact terminal 1 shown in FIG.
2, bend the connecting piece 13 at a right angle, and follow the bending line 23.
The terminal leg portion 12 is bent at a right angle so that the plate surfaces of the spring contact portion 11 and the terminal leg portion 12 are perpendicular to each other, so that the overall shape is approximately L-shaped. Note that when the spring contact portion 11 is bent along the bending line 21 as shown by the two-dot chain line, it will be in the state shown in FIG. 3.

The configurations shown in FIGS. 3 and 4 are effective in preventing flux failures.

In the contact terminal 1 shown in FIG. 5, the spring contact part 11 and the connecting piece part 13 are bent in a direction perpendicular to each other along the bending line 21, and the connecting piece part 13 is bent at the bending line 22 at the part adjacent to the terminal leg part 12. is bent at right angles in the direction approaching the spring contact part 11, and the bending line 2
3, bend the terminal leg part 12 at right angles in the direction away from the spring contact part 11, and
The plate surfaces of the terminal leg portion 12 and the terminal leg portion 12 are arranged in the same plane, and the overall shape is approximately L-shaped.
Here, if the bending along the bending line 21 is not performed, a structure similar to that shown in FIG. 4 will be obtained as shown by the two-dot chain line.

FIG. 6 is a plan view showing the unfolded state of a specific contact terminal 1 used in the jack of the present invention.
3 shows an example in which a notch portion 14 is provided in the terminal leg portion 12 adjacent to the terminal leg portion 3.

7 to 9 show specific examples of the jack 3 according to the present invention. This jack 3 is
It consists of a jack housing 4, a lid 5 that closes the opening of the jack housing 4, and a chip contact terminal 1A, a ring contact terminal 1B, and a sleeve contact terminal 1C incorporated into the jack housing 4. There is. The tip contact terminal 1A has a spring contact portion 11 bent at its tip to form a contact portion 1D that contacts the tip of the plug. A break contact 6 is normally brought into contact with the intermediate portion of the spring contact portion 11. The ring contact terminal 1B has a spring contact portion 11 bent at its intermediate portion to form a contact portion 1E that contacts the ring of the plug. A break contact 7 is usually located at the tip of the spring contact part 11.
are increasingly being contacted. The sleeve contacting contact portion 1C is formed by bending the middle portion of the spring contact portion 11 to form a contact portion 1F that contacts the sleeve of the plug.

(Effect of the invention) The contact terminal of the jack according to the invention has a shape in which the spring contact part and the terminal leg part are connected by the connecting piece part in a direction that intersects with each other when it is unfolded in a flat state. In this state, the spring contact part and the terminal leg part are oriented parallel to each other, so it can be manufactured without wasting material.
The cost can be reduced, and therefore the cost of the jack can be reduced.
