Description

A fork terminal {Fork Terminal}

The present invention relates to a fork terminal, and more particularly to a fork terminal in which the shape of a fork terminal is formed to prevent stress from being received by the contact portion upon contact with an opponent terminal.

Various circuit components such as fuses and relays are mounted on circuit boards used in various electric circuit systems. In order to assemble the components on the circuit board, an electrical terminal of a proper shape must be provided.

The electrical terminals are mainly manufactured using a copper alloy, and inserted into a circuit board or the like to electrically and mechanically connect various components. A fork terminal is a kind of such a terminal, and it is assembled in such a manner that a circuit board or an opponent terminal is inserted between two fingers.

1 and 2, the terminal body 1 of the prior art has a flat terminal shape. Two fingers 5 extend from one side of the terminal body 3, and the fingers 5 are integrally formed with the terminal body 3. An insertion space 6 into which a mating terminal (not shown) is inserted is formed between the fingers 5, The connection 5 'is formed between the rejects 5.

A contact portion 7 is formed at the tip end of the finger 5 so that the contact portions 7 are protruded in directions opposite to each other and the moment the contact terminal 7 is inserted into the insertion space 6, . At this time, the fingers 5 are elastically deformed in correspondence with the mating terminal so that the mating terminal is firmly fixed to the fork terminal 1 while inserting the mating terminal.

However, when elastic deformation occurs between the two fingers 5, the stress is concentrated around the connection portion 5 'of the terminal body 3 to cause plastic deformation or damage . Particularly, plastic deformation of the terminal body 3 occurs more frequently when terminals are connected and disconnected repeatedly.

The fork terminal 10 of this embodiment shown in Figs. 3 and 4 has a terminal body 11 made of a metal in a flat plate shape. The terminal body 11 is integrally formed with the terminal body 11 by extending two fingers 15 from the body portion 13 and a body portion 13 which can be electrically connected to the components.

The fingers 15 are formed such that the faces facing each other are inclined so that the width becomes narrower toward the front end. The fingers 15 are formed to be elastically deformable in a predetermined direction about the body 13.

An insertion space 16 into which the mating terminal T is inserted is formed between the fingers 15 and the insertion space 16 is formed larger toward the tip of the finger 15. That is, the tip ends of the finger fingers 15 corresponding to the inlets into which the counterpart terminals T are inserted are formed to be large. In this embodiment, one side of the finger 15 is inclined so that the insertion space 16 is formed in a substantially triangular shape.

A connection portion 17 is formed between the body portion 13 and the finger 15 and a contact portion 20 is formed at the tip of the finger 15. The contact portion 20 is provided with a plurality of The contact protrusions 22 are protruded in the viewing direction. The contact protrusion 22 protrudes toward the insertion space 16 so as to have a convex curved surface and a depression 24 is formed at one side of the contact protrusion 22 toward the connection part 17 of the insertion space 16 .

The recessed portion 24 is formed to have a concave curved surface toward the tip of the finger 15 at a portion where the contact protrusion 22 and the finger 15 are connected to each other, And is elastically deformable toward the finger 15 as soon as it is inserted into the finger 16.

Hereinafter, the use of the fork terminal according to the present invention having the above-described configuration will be described in detail.

The body portion 13 provided on the terminal body 11 of the fork terminal 10 is connected to a fuse or a relay which requires electrical connection but this is not the main content of the present invention and will not be described in detail.

As shown in FIG. 5, a relative terminal T is inserted between the fingers 15 extending from the body portion 13. As shown in FIG. The counter terminal T is in the form of a flat plate such as a tap terminal and the tip of the counter terminal T contacts the contact portion 20 provided at the tip of the finger 15 in advance.

When the mating terminal (T) is brought into contact with one side of the contact protrusion (22) formed on the contact portion (20) of the finger 15, stress is applied to the connection portion (17) .

On the other hand, when the counterpart terminal T is continuously inserted, stress is applied to the depressed portion 24 of the contact portion 20 so that the contact protrusion 22 starts to be elastically deformed toward the finger 15 side.

As a result of the insertion of the mating terminal T, the contact protrusion 22 at the tip end of the finger 15 and the finger 15 itself are elastically deformed at the same time. Therefore, when the mating terminal T is inserted, the stresses can be dispersed in the connecting portion 17 and the depressed portion 24 of the terminal body 11, respectively.

According to this configuration, as compared with the case where the stress is concentrated on the connecting portion 5 'in the existing fork terminal 1, the contact protrusion 22 of the present invention is elastically deformed by the depressed portion 24, It is possible to prevent stress from being dispersed to cause plastic deformation or breakage during the insertion process of the counterpart terminal (T).

The description above is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Accordingly, the embodiments disclosed in this specification are intended to illustrate and not to limit the technical idea of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas which are within the scope of the same should be interpreted as being included in the scope of the present invention.

For example, as shown in FIG. 6, the recessed direction of the depression 24 may be formed perpendicular to the extending direction of the finger 15, And may be formed in the same direction as the extended direction (b).

In addition, a concave groove 25 may be formed at one side of the depression 24 to facilitate the elastic deformation of the contact protrusion 22 (c). All of these various examples need only to facilitate the elastic deformation of the contact protrusions 22 so as to disperse the stress concentrated on the connecting portions 17 most appropriately.
