Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a fuse box used for electric wiring of a vehicle.

[Conventional technology]

As shown in FIG. 5, a conventional fuse box has a cavity 5 into which a terminal 3 is inserted in a box body 1 so as to face each other.
After arranging a plurality of them, and inserting and locking the terminal 3 in which the electric wire 4 is crimped into each cavity 5 from below the main body 1, the tab-shaped contact portions 2a, 2a of the fuse 2 are respectively inserted from above from a pair of terminals. It has a structure in which it is inserted and connected between the elastic holding pieces 3a, 3a.

[Problems to be solved by the device]

As shown in FIG. 5, the fuse box A has four electric wires,
That is, it is in a state of being connected to the wire harness W.

Therefore, the attachment of the fuse 2 cannot be automated by a machine, and the fuses 2 must be manually attached one by one, which hinders improvement in productivity.

An object of the present invention is to solve the above problems and provide a fuse box having a structure capable of automating the attachment of a fuse.

[Means for Solving the Problems]

In order to achieve the above object, the fuse box of the present invention is formed by dividing the box body into a fuse case and a terminal case, and a plurality of cavities are provided in the terminal case to crimp and connect electric wires. A terminal is inserted, and a tab insertion hole that communicates with each of the plurality of cavities is provided in the fuse case, and a fuse locking portion is provided at a hole edge of the tab insertion hole, and is inserted into the tab insertion hole. A structure is adopted in which the attached fuse is locked by the fuse locking portion and the fuse and the terminal are connected by assembling the fuse case and the terminal case.

Hereinafter, the above configuration will be specifically described with reference to the drawings showing an embodiment.

〔Example〕

FIG. 1 is an exploded perspective view of the fuse box B, FIG. 2 is a partial sectional view of the same as the assembled state, FIG. 3 is an enlarged perspective view of the fuse locking portion, and FIGS. The explanatory view of the working state of was shown.

In these figures, the box body of the fuse box B is divided into two parts, a fuse case 10 and a terminal case 11, and the case 10 and 11 have locking claws 12 and locking holes 13a. And a locking means consisting of a locking piece 13 having

As in the conventional case, the terminal case 11 is provided with a plurality of cavities 5 that are open at the top and bottom, arranged vertically and horizontally, and each cavity 5 has two terminals 3 crimped to the ends of the electric wires 4. It is housed opposite.

A downward lance 3c is cut and formed on the base plate portion 3b of the terminal 3 (FIG. 2), and the lance 3c is engaged with a groove (not shown) provided in the inner wall of the cavity 5 so that the lance 3c does not come out downward. It is blocking.

The fuse case 10 is provided with a plurality of tab insertion holes 14. The tab insertion hole 14 is formed as an elongated hole communicating with the cavity 5, and a stopper 14a for the body portion 2b of the fuse 2 is provided at the center of the hole 14.

A fuse locking portion 15 is provided on the hole edge of the tab insertion hole 14 as shown in an enlarged view in FIG. The fuse locking portion 15 is formed of a pair of flexible falling prevention walls 16 that face each other.
And a locking wall 17. The fall-off prevention wall 16 is in contact with the side surface of the body portion 2b of the fuse 2 and engages with the lower surface of the head portion 2c.
Have a on both sides. The locking wall 17 has hook-shaped locking pieces 17a on both sides that engage with the upper surface of the head 2c. As shown in FIG. 2, the protruding length of the hook portion 17b of the locking piece 17a is smaller than the width d of the head 2c of the fuse 2, and the tab of the fuse 2 is provided between the tip of the hook 2b and the fall prevention wall 16. Insertion space S of the circular contact portion 2a
To leave.

[Action]

As shown in FIGS. 4A to 4C, tab-shaped contact portions of the fuse 2
When 2a is pushed vertically from the insertion space S of the fuse locking portion 15 (a), the fall prevention wall 16 and the locking wall 17 respectively bend outward and expand (b). When pressed further, both walls 16,1
7, the projections 16a come into contact with the lower surface of the head 2c due to the elastic return of both walls 16 and 17, and the locking piece 17a (the hook portion 17b thereof) is attached to the head 2c.
The fuse 2 is locked by engaging the upper surface of the fuse (c).

Thus, the fuse 2 is inserted into the tab insertion hole 14 of the fuse case 10 by the fuse locking portion 15 in a locked state. As shown in FIGS. 4 (a) to 4 (c), the insertion may be performed by pushing vertically, and can be automated by a machine.

Therefore, as shown in FIG. 1, the fuse 2 can be separately attached to the fuse case 10, and the terminal 3 can be separately attached to the terminal case 11.

When the fuse case 10 is assembled to the terminal case 11 in this state, the tab-shaped contact portion 2a of the fuse 2 is fitted between the elastic clamping pieces 3a, 3a of the terminal 3 as shown in FIG. A plurality of fuses 2 and terminals 3 are simultaneously connected.

[Effect of device]

As described above, according to the present invention, the fuse is attached to the fuse case, and the terminals connected to the electric wires are separately inserted and locked into the terminal case. It can be done independently of the terminal case connected to the, and can be automated by a machine, which is expected to improve productivity.
