Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a relay terminal incorporated in an electric connection box of a wire harness for an automobile and used.

[Prior Art] As shown in FIG. 2, a relay terminal 1 incorporated in a conventional electric connection box of a wire harness for an automobile has a box / tongue-shaped female terminal portion 2 and a faston-shaped female terminal portion 3 as shown in FIG. And had an integrally formed female-male structure. In the box / tongue-shaped female terminal portion 2, the tongue piece 5 integrated with the box body 4 is folded back and inserted into the entrance of the rectangular box body 4, and the tongue piece 5 is inserted into the entrance of the box body 4. It had a structure in which the insertion guide pieces 6 were provided so as to face each other.

In such a relay terminal 1, the faston-type female terminal portion 3 is connected to a terminal 7 of a bus bar in an electric connection box (not shown), and the box / tongue-shaped female terminal portion 2 is connected to a terminal 8 of an electronic component such as a fuse or a relay. Used by connecting.

As shown in FIG. 3, the relay terminal 1 having such a structure can be continuously manufactured by connecting the carrier 10 with the connecting portion 9 provided in the faston-type female terminal portion 3.

Due to the recent decrease in the electric components such as fuses and relays used in electrical junction boxes, it is necessary to downsize the relay terminal 1 as well, and the conventional faston female terminal 3 cannot stabilize the quality. , Both need to be box / tongue-shaped female terminals.

On the other hand, as a type different from this, as shown in FIGS. 4 and 5, the terminal outer component 11 and the terminal outer component which are separate components from each other.
A relay terminal 1 has been proposed, which is composed of an in-terminal component 12 incorporated in an inside 11. In this case, the outer terminal component 11 has a structure in which both ends have faston-shaped female terminal portions 13, and the inner terminal component 12 mainly has an arched plate body 14. The terminal internal component 12 is incorporated into the terminal external component 11 by being prevented from coming off by locking the projections 15 at both ends of the arch-shaped plate 14 to the notches 16 of the terminal external component 11.

[Problems to be Solved by the Invention] However, in the relay terminal 1 of the one-article type as shown in FIG. 2, both of which are box / tongue-shaped female terminal portions 2, because the tongue pieces 5 are provided, they are connected. The part 9 cannot be provided,
Therefore, there is a problem that the relay terminal 1 cannot be continuously manufactured.

On the other hand, in the case of the two article type as shown in FIGS. 4 and 5, since the connecting portion can be provided, the relay terminal 1 can be continuously manufactured.
Therefore, there is a problem that the quality cannot be stabilized.

An object of the present invention is to provide a relay terminal which can be continuously manufactured even in the form of a box and tongue.

[Means for Solving the Problems] The structure of the present invention for achieving the above-mentioned object will be described. The present invention includes a terminal external component and a terminal internal component incorporated in the terminal external component which are separate from each other. In the relay terminal, which has a female structure at both ends for connection, the outer terminal component is a box-shaped structure having a box body with opposite ends opened, and the inner terminal component Is composed of a spring structure having tongues at both ends of the board, and the internal terminal parts are incorporated with the tongues facing the respective box parts of the external terminal parts.

[Operation] When a relay terminal is formed by a combination of the box-shaped external terminal component having a box body and the spring-shaped external terminal component having tongues at both ends, all of these components are connected to the carrier. A connecting part can be provided, which allows continuous production of these parts.

Also, since both ends of this relay terminal are box-shaped and tongue-shaped, the quality can be stabilized more easily than the faston type.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG.

The relay terminal 1 of the present embodiment is a terminal external component 11 which is a separate component from each other.
And the internal terminal part 12 incorporated in the external terminal part 11 is the same as that shown in FIGS. 4 and 5 described above.

The external terminal component 11 of this embodiment has a box-shaped structure in which both ends are a box body 4, and each end of the box body 4 is open. An insertion guide piece 6 and a connecting portion 9 are provided at the entrances of the boxes 4 so as to face each other. Locking holes 17 are provided on both sides of the center of the external terminal component 11. The in-terminal component 12 is formed of a spring structure in which the tongue piece 5 is provided by folding back from both ends of the board 18, and the connecting portion 19 is provided in the center of the board 18.

Such an in-terminal component 12 is assembled in the out-terminal component 11 with the tongues 5 facing the respective box bodies 4. In this case, the connecting portion 19 of the internal terminal component 12 is inserted into the locking hole 17 of the external terminal component 11 to prevent the internal component 12 from coming off.

A box-shaped external terminal component 11 having such a box body 4,
When the relay terminal 1 is formed in combination with the internal terminal part 12 having the spring structure having the tongue pieces 5 at both ends, the connecting parts 9, 12 for connecting to the carrier 10 (see FIG. 3) are provided.
19 can be provided so that a continuous production of these parts 11, 12 can take place. Also, this relay terminal 1
Since both ends are box-shaped and tongue-shaped, the quality can be stabilized compared to the faston type.

In addition, it is also possible to lock the internal terminal component 12 to the external terminal component 11 by making the slit 20 between the adjacent box bodies 4 deep and fitting the connecting portion 19 of the internal component 12 into the slit 20. it can.

Also, bend the connecting portion 19 to the side opposite to the tongue 5 side,
By locking the connecting portion 19 in the hole on the bottom surface of the external terminal component 11, the internal terminal component 12 can also be locked in the external terminal component 11.

Further, the locking of the internal terminal part 12 to the external terminal part 11 can also be performed by cutting and raising a locking piece different from the connecting part 19 from any one of the parts and locking it in the hole of the other part. it can.

[Advantages of the Invention] As described above, the present invention forms the relay terminal by combining the box-shaped external terminal component having the box body and the spring-shaped external terminal component having the tongue pieces at both ends. Therefore, any of these parts can be provided with a connecting part for connecting to the carrier, and thus continuous production of these parts can be performed. Also, since both ends of this relay terminal are box-shaped and tongue-shaped, the quality can be stabilized more easily than the faston type.
