Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector terminal structure.

[0002]

2. Description of the Related Art Leads of board connector terminals are soldered to a board. Therefore, the alignment of the connector terminals with respect to the solder through hole or the soldering pattern is important. In particular, in recent narrow-pitch connectors, if there is a slight irregularity, there is a problem that the through-hole cannot be inserted or the solder cannot be soldered to a correct position. The reason for this is that when pressing the connector terminal, the cross section of the lead 10 is not finished in a square shape, but becomes a polygonal shape (pentagonal shape) as shown in FIGS.

[0003]

As described above, in the conventional example, the lead 10 has a polygonal shape (pentagonal shape) because the cross section of the lead 10 is not finished in a square shape, but is formed in a polygonal shape (pentagonal shape).
When bending is performed using the jigs 12 and 13, the force point b is shifted with respect to the fulcrum a as shown in FIG. 6 at the time of bending, so that the lead 10 rolls and twists, and as shown in FIG. There has been a problem that the lead 10 of the terminal is bent obliquely and irregular.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a connector terminal structure in which the leads of the connector terminals are straightened and the board mounting is improved even though the connector is a narrow pitch connector. .

[0005]

To achieve the above objects resolving means for the, the present invention is a partial cross-sectional shape of bending after the connector terminal leads, I the fulcrum side to the power point at the time of partially bending the And the other part is formed as a linear part .

[0006]

With this configuration, when the lead is bent using the jig, the power point does not shift with respect to the fulcrum at the time of bending, and the lead is straightened without the problem that the lead is rolled and twisted. For this reason, the leads of the connector terminals are aligned straight, and the mounting on the substrate is improved even though the connector is a narrow pitch connector.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a connector having a connector terminal structure according to the present invention, and FIG. 2 is a plan view of the connector terminal. The connector includes a synthetic resin housing 1.
The leads 5 of a large number of connector terminals 4 are exposed at predetermined intervals on both sides of the rear surface 2 of the housing 1, and these leads 5 are bent at substantially right angles in the middle. . Then, one side is arcuate A sectional shape of the lead 5 is a four square as shown in FIG. 3 (b)
As shown in ( b ), a part is formed as a semi- circular arc, and the other part is
Is press-molded into any of those which are formed linearly .

As described above, the cross section of the lead 5 has a linear portion.
For those having a circular arc portion 7 to the arc-shaped portion and the flat surface 6 to be formed is formed and bent the lead 5 using a jig, without emphasis b deviates from the fulcrum a at bending, The lead 5 is straightened without the problem of rolling and twisting. Therefore, the leads 5 of the connector terminal 4 are aligned straight as shown in FIG.

[0009]

As described above, according to the present invention, the cross-sectional shape of the part of the connector terminal that is bent after the lead is partially changed.
An arc-shaped portion ing the fulcrum side to the power point at the bend, the other
Is formed as a linear part, so that when the lead is bent using a jig, the power point does not shift with respect to the fulcrum at the time of bending, and there is no problem that the lead rolls and twists occur, and it is straightened . For this reason, the leads of the connector terminals are aligned straight, and the mounting on the substrate is improved even though the connector is a narrow pitch connector.
