Abstract

(57) [Summary] [Structure] A connector formed by bending a tab to be inserted and connected to a continuity check portion of a fuse to be connected was embedded in the back surface of the fuse cover with the tab protruding. [Effect] By embedding the connector for connecting the fuses to be connected to each other on the back surface of the fuse cover, the busbars can be stacked even if the space for the busbar for the fuse circuit cannot be secured in the electrical connection box. Instead, a fuse circuit can be configured. Further, by disposing the connector on the back surface of the fuse cover so as to cope with the design change, the design change can be dealt with at any time. Further, since the tab formed on the connector is directly inserted and connected to the continuity check portion of the fuse, an intermediate connection terminal is not required, which is extremely economical. Therefore, it is possible to inexpensively provide a small-sized electrical junction box that can respond to design changes at any time.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an electric connection box used for wiring in an automobile.

[0002]

[Prior Art]

 As shown in FIG. 5, in a conventional electric connection box used for wiring in an automobile, a fuse 24 is connected to a tab 22 of a bus bar 21 arranged in the electric connection box 20 via an intermediate connection terminal 23. Was configured.

[0003]

[Problems to be solved by the device]

 However, in the electrical junction box configured as described above, when the space for arranging the bus bar 21 for connecting the fuse 24 cannot be secured at the stage of pattern design, the bus bar 21 is laminated as shown in the figure to form a fuse circuit. However, if the fuse circuit is formed by stacking the bus bars 21, the electric junction box will not only be large, but it will be uneconomical. Also, even if the fuse circuit is expanded, the existing electrical junction box will be used. No. 20 had a problem that it was extremely difficult to add more because the space for the fuse circuit was already defined.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an electric junction box that is small in size and can extremely easily add a fuse circuit due to a design change or the like at low cost.

[0005]

[Means for Solving the Problems]

 In the present invention, an electrical junction box is constructed by embedding a connector, which is formed by bending a tab to be inserted and connected to a continuity check portion provided in the fuse, by embedding the tab on the back surface of the cover covering the fuse with the tab protruding. This is a solution to the conventional problems.

[0006]

[Function] By covering the fuse mounting portion provided in the electrical junction box with the fuse cover, the tab formed by bending the connector embedded in the back surface of the fuse cover is inserted and connected to the fuse continuity check portion to be connected, Hold the fuse cover on the electrical junction box by forcibly fitting and locking the frame-shaped locking protrusions provided on both sides of the fuse cover with the locking protrusions provided on both sides of the fuse mounting part of the electrical junction box. By fixing, the fuses to be connected are electrically connected to each other by the connector.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 is a partially exploded perspective view showing an embodiment of the present invention, FIG. 2 is a sectional view of a fuse cover constituting the present invention, FIG. 3 is an exploded perspective view showing a circuit configuration, and 1 is an electric junction box, Reference numeral 2 denotes a fuse mounting portion provided on the electric connection box 1, and 3 denotes locking protrusions provided on both side surfaces of the fuse mounting portion 2. Reference numeral 4 denotes a plurality of fuses detachably arranged in the fuse mounting portion 2 and 4a denotes a continuity check portion provided in the fuse 4. Reference numeral 5 denotes a fuse cover detachably attached to the electric connection box 1, 6 denotes frame-shaped locking projections provided on both side surfaces of the fuse cover 5, and the frame-shaped locking projections 6 are attached to the electric connection box 1. By fitting and locking the locking projections 3 provided on both side surfaces of the fuse mounting portion 2, the fuse cover 5 is securely and firmly held in the electrical junction box 1. Reference numeral 7 is a connector made of a conductive metal plate in which tabs 7a, 7a are formed by bending and inserting tabs 7a, 7a into the conduction check portions 4a, 4a of the fuses 4, 4 to be connected. The tabs 7a, 7a are embedded so as to project.

By constructing the electrical junction box as described above, the fuse mounting portion 2 provided on the electrical junction box 1 is covered with the fuse cover 5, so that the connector 7 embedded in the back surface of the fuse cover 5 is bent. The formed tabs 7a, 7a are inserted into and connected to the continuity check portions 4a, 4a of the fuses 4, 4 to be connected, and the frame-shaped locking projections 6 provided on both side surfaces of the fuse cover 5 are mounted on the electrical connection box 1 as fuses. The fuses 5 to be connected are connected by the connector 7 by forcibly fitting and locking the locking protrusions 3 provided on both side surfaces of the portion 2 and holding and fixing the fuse cover 5 in the electrical junction box 1. The electrical connection is ensured, and electrical accidents such as poor continuity due to automobile vibration are reliably prevented.

Therefore, it is not necessary to stack the bus bars forming the fuse circuit as in the conventional case, so that not only can the electrical junction box be downsized, but as described above, the tabs 7a, 7a formed by bending the connector 7 can be formed. Is directly connected to the conduction check portions 4a and 4a of the fuses 4 and 4, so that it does not require an intermediate connection terminal and is extremely economical. In addition, a plurality of connectors 7 are embedded in the fuse cover 5 in advance so as to cope with design changes, and unnecessary tabs 7a are cut during mounting, or connections are made so that design changes can be accommodated. By providing in advance several kinds of fuse covers 5 in which the child 7 is embedded, design changes can be dealt with at any time. Further, as shown in FIG. 4, by providing the fuse cover 5 with an outlet 8 for energizing the connector 7, it is possible to configure a circuit for energizing the fuse 4 from the connector 7.

Although the electric junction box has been illustrated and described above, the present invention is not limited to this and can be applied to a fuse box.

[0011]

[Effect of the device]

 According to the present invention, as described above, it is possible to inexpensively provide an electric junction box which is small and can cope with design changes at any time, and the fuse cover 5 is provided with an outlet 8 for energizing the connector 7. As a result, there is an excellent advantage that a circuit for energizing the fuse 4 from the connector 7 can be configured.
