Description

[Detailed Description of the Invention] The present invention relates to an electric wire fuse holder that can connect a fuse and an electric wire with one touch.

Generally, a fuse 1 has metal caps 3, 3 attached to both ends of a glass tube 2, as shown in FIG.
The structure is such that both ends of the fusible body 4 inserted into the glass tube 2 are soldered to caps 3, 3.

Conventionally, a fuse holder supporting such a fuse 1 has a case member 5 as shown in FIG.
and the cap member 6, and the electric wire 8A is drawn into the inside of the case member 5 through the spring 7.
and the presser terminal 9B attached to the electric wire 8B drawn inside the cap member 6.
The current trend is to support Hughes 1 between the two countries.

In the fuse holder of the above structure, first, the electric wires 8A, 8B are passed through the case member 5 and the cap member 6, and then the electric wires 8A, 8B are held by the terminals 9A, 9.
It can be assembled by soldering B.

However, as a pre-process for soldering the presser terminals 9A, 9B, the vinyl coating 10 of the electric wires 8A, 8B must be peeled off to expose the copper wire 11, which further requires a troublesome soldering work. Therefore, there were drawbacks such as poor workability and decreased reliability of the product due to poor soldering.

The present invention was developed in view of these conventional drawbacks, and eliminates the need for stripping and soldering of wires, allowing wires and fuses to be connected with a single touch, improving workability and reliability. It provides a wire fuse holder.

The present invention will be described in detail below with reference to embodiments shown in the drawings.

3 to 9 show an embodiment of the present invention.

In the figure, 12 is a support base, and 13 is a cover, which are connected by a hinge 14 so as to be openable and closable, and are integrally molded from plastic such as nylon or polypropylene.

The support stand 12 has clip seats 15A and 15B spaced apart from each other on the center side thereof to support both ends of the outer periphery of the fuse 1, and semicircular clip seats 15A and 15B are provided on both sides of the support stand 12 along the longitudinal direction of the support stand 12. Groove 16
A, 16B are formed. This groove 16A, 1
6B has claws 17A and 17B protruding from the claw 1.
7A, 17B and the clip seats 15A, 15B are electrically connected together by a connecting plate 18, and this connecting plate 18 is buried in the support base 12.

The clip seat 15A, the claw 17A, and the connecting plate 18 are integrally formed by punching and molding a brass plate or the like, as shown in FIG. Support pieces 19, 19 on both sides of the claws 17A, 17B
Embedded in and supported on both sides.

Furthermore, grooves 16A, 1 are provided on the upper surface of the support base 12.
A semicircular groove 20 is formed in parallel to 6B, and protrusions 21 are provided on both sides of the support base 12.

The cover 13 has a hollow part 22 formed in the center thereof into which the fuse 1 is inserted, and grooves 16 of the support base 12 on both sides along the longitudinal direction.
Semicircular grooves 23A, 23 corresponding to A, 16B
B is formed. Furthermore, these grooves 23A, 23B
E-shaped cut grooves 24A, 24B into which the claws 17A, 17B are inserted are formed in the intermediate portions of the two.

Further, a semicircular groove 25 corresponding to the groove 20 provided in the support base 12 in parallel with the grooves 23A and 23B.
A stopper 26 is formed on the side surface of the cover 13 and detachably engages with the protrusion 21.
is provided. Note that 27 is a ventilation hole.

Next, the operation of the electric wire fuse holder having the above structure will be explained.

As shown in FIG. 8, the fuse 1 is fitted into the clip seats 15A and 15B and fixed. Two electric wires 8, 8 are integrally covered with vinyl and placed side by side, and the cord is separated from the middle, one electric wire 8 is cut, and the other electric wire 8 is cut into electric wires 8A, 8B, and the other electric wire 8 is inserted into the groove of the support base 12. Fit it to 20.

On the other hand, the cut wires 8A and 8B have their ends supported by support pieces 19 and 19, respectively, with claws 17A and 1.
Fit it into 7B.

In this state, as shown in FIG. 9, when the cover 13 is placed over the support base 12 and the cover 13 and the support base 12 are tightened using a tightening tool 28 such as pliers or pliers, the claws 17A and 17B are attached to the wires 8A and 8B. It breaks through the vinyl coating 10 and bites into the copper wire 11 so that the tip penetrates and is connected, and the stopper 26 engages with the protrusion 21 to fix the cover 13.

Therefore, the electric wires 8A, 8B can be connected to both ends of the fuse 1 with one touch by the bite of the claws 17A, 17B, and since the claws 17A, 17B bite into the copper wire 11, the connection can be ensured.

In addition, in the above structure, the support base 12 is provided with a groove 20, and the cover 13 is also provided with a corresponding groove 25, and the other electric wire 8 is held between both grooves 20 and 25, so that the other electric wire 8 is held between the two grooves 20 and 25. Also, separation of both electric wires 8, 8 can be prevented.

In the above embodiment, the clip seats 15A and 15B
Although a groove structure is shown in which the outer periphery of the fuse 1 is clamped and fixed, any shape may be used, such as one in which a plate spring is bent into an inverted U shape and both ends of the fuse 1 are pressed and fixed.

In addition, the grooves 20 and 25 for holding one of the electric wires 8 may not be provided in particular, and the structure may be made smaller, and the support stand 12 and the cover 13 may be molded from transparent plastic, so that the fuse 1 stored and held inside can be formed. The cut can be seen from the outside without removing the cover 13.

As explained above, according to the electric wire fuse holder of the present invention, the conventional work of peeling the vinyl coating, soldering, and caulking is completely unnecessary, and the electric wire and the clip seat that supports the fuse can be attached with a single touch. The assembly process, which conventionally took 3 minutes per piece, can be reduced to about 30 seconds.It has excellent workability and reliability, and is especially effective for electrical equipment manufacturers engaged in mass production. able to demonstrate.
