Description

The present invention relates to a connector terminal.

A conventional connector terminal has a long-shaped holding portion, an elastic arm portion formed by extending from one end of the holding portion, an abutting portion formed by being bent in an arc shape from the end of the elastic arm portion, and a holding portion And a welded portion formed by extending from the other end. A normal holding part, an elastic arm part, a contact part, and a welding part are formed by processing the board material of the same thickness.

However, in the above-described conventional connector terminal technology, that is, when the above-described connector terminal is applied to an ultra-thin connector, the connector terminal of the same thickness is fixed in thickness and thin, so that the attaching / detaching force is small. Moreover, the structural strength was insufficient. Therefore, the present inventor considered that the above-mentioned drawbacks could be improved, and as a result of intensive studies, he came up with a proposal for the present invention to improve the problem reasonably and effectively.

The present invention has been made to solve the above-described conventional problems, and a main object of the present invention is to provide a connector terminal that increases the attachment / detachment force and the structural strength in order to solve the above-described problems. There is to do.

In order to solve the above-described problems and achieve the object, a connector terminal according to the present invention includes a holding portion that has an arc shape in the extending direction, an elastic arm portion that has an arc shape connected to one end of the holding portion, and a holding portion. And the arcuate shape is formed so that the entire elastic arm part protrudes outward, the contact part formed by recessing the end of the elastic arm part inward, and the other end of the holding part is bent inward. Contact portions formed by extending both sides toward the back after stretching, and the thickness of the holding portion and the elastic arm portion is non-uniform, from the holding portion toward the end of the elastic arm portion The thickness is gradually reduced.

As described above, the connector terminal according to the present invention gradually decreases in thickness from the holding part to the end of the elastic arm part, and both the holding part and the elastic arm part exhibit an arcuate outline. The structural strength and the vertical resistance of the terminal are greatly improved. Further, since the contact portion is thin, the function of the elastic terminal is achieved.

It is an external appearance perspective view which shows the connector terminal which concerns on 1st Embodiment of this invention. It is a side view of the connector terminal shown in FIG. It is a top view of the connector terminal shown in FIG. FIG. 2 is a perspective sectional view in which the connector terminal shown in FIG. 1 is attached to the connector.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiment described below does not limit the contents of the present invention described in the claims of the utility model registration. In addition, all the configurations described below are not necessarily essential requirements of the present invention.

(First embodiment)
Hereinafter, the present invention will be described with reference to FIGS. That is, the configuration of the first embodiment of the present invention is shown in FIGS. The connector terminal 100 according to the present invention includes a holding portion 10 that is stretched and has an arc shape in the extending direction, an elastic arm portion 20 that has an arc shape connected to one end of the holding portion 10, and the holding portion 10 and the elastic arm portion 20 are outside. The contact portion 30 is formed in an arc shape so as to protrude toward the end, the end of the elastic arm portion 20 is recessed inward, and the other end of the holding portion 10 is curved inward and extended. Later, both sides have contact portions 40 that are formed to extend backward. The thickness of the holding part 10 and the elastic arm part 20 is not uniform, and the thickness from the holding part 10 toward the end of the elastic arm part 20 is gradually reduced.

A convex hull 11 used for spot welding and fixing to an external device is provided on the outer surface of the holding part 10. The convex hull is provided on the outer surface close to one end of the holding portion 10, and lock grooves 12 are formed on both sides of the position close to one end of the holding portion 10, respectively, and are used for locking to an external device.

The width of the elastic arm portion 20 is larger than the width of the holding portion 10, and the width of the elastic arm portion 20 gradually decreases from one end connected to the holding portion 10 to the end.

The contact portion 30 is formed by being bent inward from the end of the elastic arm portion 20 toward the holding portion 10 and then extending forward, and then being bent and extended obliquely outward. The portion 30 is thinner than the elastic arm portion 20.

The abutting portion 40 is bent and extended from the other end of the holding portion 10 to the inside, and is bent and extended from both sides of the bending portion 41 toward the rear outside. The contact pin 42 is formed by extending toward the back, and a protrusion 43 is provided at the end of the contact pin 42 so as to protrude inward.

As shown in FIGS. 1 to 4, the connector terminal 100 according to the present invention employs a forging technique, and the thickness varies from the holding portion 10 to the end of the elastic arm portion 20. By gradually becoming thinner, both the holding portion 10 and the elastic arm portion 20 exhibit an arcuate outline. Since the structural strength and the vertical drag of the terminal are greatly improved, and the thickness of the contact portion 30 is thin, the function of the elastic terminal is achieved.

As described above, the connector terminal 100 according to the present invention is such that the holding portion 10 gradually decreases in thickness over the end of the elastic arm portion 20 so that both the holding portion 10 and the elastic arm portion 20 are arced. It exhibits the shape outline, the structural strength and the normal resistance of the terminal are greatly increased, and the thickness of the contact part 30 is thin, so that the function of the elastic terminal is achieved.

As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
