[0001]

BACKGROUND OF THE INVENTION The present invention relates to a composite flat terminal used for connecting two electric wires to a battery terminal or the like.

[0002]

2. Description of the Related Art As a conventional composite flat terminal, for example, there is one as shown in FIG. FIG. 6 shows a case where the electric wire 5 for the vehicle power supply and the other electric wires 7 are connected to the terminal 3 of the battery 1, and includes a thick terminal 9 and a thin terminal 11. The thick terminal 9 is formed of a thick terminal plate 13 and includes a bolt insertion hole 15 and an electric wire connecting portion 17, and the electric wire for vehicle power supply 5 is connected to the electric wire connecting portion 17. The thin terminal 11 is formed of a thin terminal plate 19 and has a bolt insertion port 21 and an electric wire connection portion 23. The other electric wire 7 is connected to the electric wire connection portion 23. Then, the terminals 9 and 1 are connected to the studs 25 erected on the terminal 3 of the battery 1.
One of the bolt insertion holes 15 and 21 is inserted, and the nuts 27 are tightened together.

[0003]

However, in such a structure, the terminal plates 13 and 19 are merely overlapped and fastened together, and the terminal plates 13 and 19 are likely to be displaced. Due to such misalignment, the nut 27
Was easy to loosen. Furthermore, embedded bolt 2
Since both terminals 9 and 11 must be inserted separately into the terminal 5, there is a risk that the thin terminal 11 may be forgotten to be mounted.

On the other hand, there is one disclosed in Japanese Utility Model Laid-Open No. 2-46376 as shown in FIG. In this example, both are thin terminals 29 and 31, and one thin terminal 29 is provided with an engagement hook 33 and a cut-and-raised piece 37 provided with a locking hole 35, and the other thin terminal 29. The terminal 31 is provided with a protruding piece 41 provided with a locking hole 39 and a rising piece 45 provided with an engaging claw 43. When mounting, first, the engaging hole 33 of the protruding piece 41 is inserted into the engaging hook 33.
And then the other terminal plate 3 to one terminal plate 30
2 and the engaging claw 43 of the rising piece 45 is cut and raised to form a piece 3
The locking holes 35 are locked by elastic deformation.

However, in such a structure, both the terminal plates 30 and 32 are thin, and the engaging hook 33, the cut-and-raised piece 37, and the rising piece 45 are simply bent.
Since it is only cut and raised and further raised, it is extremely easily deformed, and the deformation of the engaging claw 43 with the locking hole 35 is easily disengaged by the deformation due to external force, so that the integrated handling can be performed. There is a risk of disappearing.

Accordingly, the present invention provides a composite flat terminal which can prevent two terminals from easily engaging each other and prevent loosening due to displacement and forgetting to attach one terminal. The purpose is to provide.

[0007]

In order to solve the above-mentioned problems, the present invention provides a terminal plate having a bolt insertion hole and a relatively thin and thick wall provided with an electric wire connection portion in the terminal plate. A thin terminal overlaps with the thick terminal, and the electric wire connection portions are connected so as not to overlap with each other. In the composite flat terminal, the terminal is located on a terminal plate side edge of the thin terminal. A pair of lock pieces opposing the terminal plate side edge of the meat terminal project toward the thick terminal, and the lock piece has an elastic locking claw that engages with the terminal plate side edge. Wherein a hook-like projection engaging with one side edge of the lock piece and a flange facing the other side edge are formed on the side edge of the thick terminal. I do.

[0008]

When the thin terminal is superimposed on the thick terminal and the lock piece of the thin terminal is engaged with the thick terminal, the two terminals can be handled integrally. Moreover, the lock piece has a hook-like projection of a thick terminal engaged with one side edge, and a flange of the thick terminal opposed to the other side edge.
It does not deform easily.

Embodiments of the present invention will be described below.

FIG. 1 is an exploded perspective view of a composite flat terminal according to an embodiment of the present invention. This composite flat terminal is used to connect the power supply wire 5 and the other wires 7 to the terminal 3 of the battery 1 in the same manner as shown in FIG. Is substantially the same as that shown in FIG. Therefore, the same components are denoted by the same reference numerals, and redundant description will be omitted.

On the other hand, in the embodiment of the present invention, as shown in FIGS. 1 to 4, a pair of lock pieces 51 project from the side edges of the thin terminal, and the tip of the lock piece 51 is thick. It is bent toward the terminal 9 of the meat and is in a protruding state. As shown in FIG. 4, a lock claw 53 having elasticity is cut and raised in these lock pieces 51 and protrudes inward. The distance H between the tips of the lock pieces 51 and the lower surface of the thin terminal plate 19 is equal to the thickness of the thick terminal plate 13.
Are slightly larger than the plate thickness t _{2 of the first} embodiment. In addition, the thickness of the thin terminal board 19 is t ₁ which is smaller than the thickness t _{2 of the} thick terminal board 13.

The thick terminal 9 has a pair of hook-like projections 55 and a flange 57 formed on a side edge of the terminal plate 13, and the flange 57 is further bent downward. ing. Then, the hook-shaped protrusion 55 and the flange 57
As a result, the connecting portion 5 with which the lock pieces 51 and 51 ′ of the thin terminal plate 19 engage with the distal end side of the thick terminal plate 13.
9, 59 '. And this connecting part 5
Width l ₁ between 9,59' Do substantially equal to the width l ₂ of the inner between the locking piece portion 51, 51 ', are those formed slightly smaller.

When the terminals 9 and 11 are fastened to the terminal 3 of the battery 1, the terminals 9 and 11 are connected in advance so as to be integrally handled. That is, when the two terminal plates 13 and 19 are overlapped so that the bolt insertion hole 21 of the thin terminal plate 19 is aligned with the bolt insertion hole 15 of the thick terminal plate 13, the lock piece 51 of the thin terminal plate 19 becomes It faces the connecting portion 59 of the thick terminal plate 13. When the thin terminal plate 19 is pressed against the thick terminal plate 13 in this state, the lock claw 53 of the lock piece portion 51 is elastically deformed, and the lock piece portion 51 enters the coupling portion 59, and the lock claw 53 becomes thick. Terminal plate 13
On the back side. At this time, even if an external force acts on the thin terminal plate 19, the movement of one side edge of the lock piece 51 is restricted by the hook-shaped protrusion 55, and the other side edge is controlled by the flange 57. Since the movement is restricted, the deformation of the lock piece 51 is suppressed, and the terminals 9 and 11 do not easily come off. Moreover, both bolt insertion holes 15,
The positioning of the terminal 21 is ensured by the relative positioning of the terminal plates 13 and 19, and can be easily performed when the terminal board 21 is mounted on the stud bolt 25 of the terminal 3.
In this manner, both terminals 9 and 11 are connected with the studs 25.
Then, if the nuts 27 are tightened, the mounting of the terminals 9 and 11 is completed. Even after mounting, both terminals 9, 11
Is restricted, and the nut 27 can be prevented from loosening. At the time of mounting to the terminal 3, since both terminals 9 and 11 can be handled integrally, there is no possibility of forgetting to mount the thin terminal 11.

[0014]

As is apparent from the above description, according to the structure of the present invention, the thick terminal and the thin terminal can be preliminarily connected to each other by the lock piece, and can be handled integrally. Is extremely easy and does not cause forgetting to attach one terminal. Further, by using a lock piece for integrating the two terminals, and by regulating the movement of the lock piece by the hook-shaped protrusion and the flange of the thick terminal plate, the relative rotation of the two terminals is reduced. This can prevent loosening of the fastening. Conversely, using a projection for regulating the relative rotation, the opening of the lock piece is regulated by making it a hook shape, and the lock claw having elasticity of the lock piece is attached to the terminal plate side edge. And it is ensured that both terminals are handled integrally.
