Description

TECHNICAL FIELD The present invention relates to an electric connection box used for electric wiring of an automobile.

2. Description of the Related Art The electric junction box has a main purpose of eliminating the octopus wiring by absorbing the joint portion of the wire harness to simplify the arrangement form and prevent enlargement. In use, as shown in FIG. 6, a connection block such as a relay block c or a fuse block d is connected in a cassette type to an end surface or a side surface of a case b of an electric connection box a and is often assembled to a vehicle body or a panel.

The connection structure is as shown in FIGS. 7a and 7b, in which a band f is inserted and locked to a lock plate e protruding from the case b side of the electric connection box, or as shown in FIG. There is one in which an insertion frame g is provided on one side and an insertion member h is provided on the other side for fitting.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the conventional connection structure, the relay block c and the like are firmly fixed to the electric connection box a in a plane. on the other hand,
Since the mounting surface and the shape of the vehicle body to which the electrical junction box is to be mounted differ depending on the destination and grade, and even in the same vehicle model, depending on whether the right handle or the left handle, the mounting position and shape of the relay block c relative to the electrical junction box a. (Angle) must be changed. Therefore, the block c cannot be shared, and it is necessary to manufacture it for each destination or vehicle type, which increases the number of product numbers and causes a high cost.

An object of the present invention is to eliminate such drawbacks and to provide an electric connection box in which the mounting posture of the connection block with respect to the electric connection box can be freely changed according to the shape of the vehicle body.

Means for Solving the Problems In order to achieve the above-mentioned object, in the present invention, in an electric junction box in which a desired connection block is detachably attached to a side surface or an end surface of a case, an attachment angle of the connection block with respect to the case It is characterized in that it can be fixed by changing.

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

Embodiments In FIGS. 1 to 4, reference numeral 1 denotes a case of an electric junction box A, 2 denotes a case of a relay block B, and both cases 1 and 2 are rotatably connected at opposing end faces.

That is, on the end surface of the case 1, the support arm 3 having the shaft holes 3a on both sides is projected, and the ridge 4 having a triangular cross section is laterally provided in the center. In addition, a bearing member 5 that is fitted between the support arms 3 and 3 is provided on the end surface of the case 2 so as to project therefrom. The tip portion of the bearing member 5 is formed in a semicircular cross section, has a shaft hole 5a at its center, and has a plurality of angle regulating grooves 6 engaging with the projections 4 on the peripheral surface with the shaft hole 5a as the center. It is provided in a saw-tooth shape in cross section.

The case 1 and the case 2 are connected by inserting the pin shaft 7 from the shaft hole 3a of the one supporting arm 3 with the ridge 4 fitted in the desired angle regulation groove 6, and then inserting the pin shaft 7 into the shaft hole 5a of the bearing member 5. Through, and the nut 8 is screwed onto the threaded portion 7a protruding from the other support arm 3. As a result, the mounting posture of the relay block B with respect to the electrical junction box A can be changed from the horizontal to the vertical direction by up to 90 °.

In addition, a connector 9 for coupling to a wire harness (not shown) is formed on both surfaces of the case 1, a relay block coupling connector 10 is formed on one surface thereof, and a relay connection portion is formed on one surface (or both surfaces) of the case 2. An electric junction box coupling connector 14 is provided together with 11, the circuit breaker connecting portion 12, and the fuse connecting portion 13. Further, another end surface of the case 1 is formed with an insertion frame 15 having a lock arm 16 that engages with a locking hole 18a of a fixed bracket 18 of the vehicle body P, and a bolt hole 17a is formed on the end surface of the case 2. The mounting plate 17 is provided so as to project, and is fixed to the weld bolt 19 of the bracket 18 'by a nut 20.

The above is an example in which the support arm 3 is provided in the case 1 of the electrical junction box A and the case 2 of the relay block B is pivotally supported, but the case may be reversed. Further, the electrical junction box A can be provided with a connection portion for a relay, a fuse, a circuit brake, etc., if necessary.

[Action]

As shown in Fig. 5a, even if the vehicle body P has a bent portion P ', if the space before and after the bent portion P'is large, it is not difficult to keep the electric junction box A and the relay block B in a substantially horizontal state, and the fixing brackets 18, 18' are provided. Can be fixed to. This also applies to the conventional electrical junction box.

On the other hand, as shown in FIG. 5b, when the vehicle body P has an obstacle due to the new installation of the optional device Q, the mounting angle of the relay block B with respect to the electric junction box A in accordance with the bending portion P'is determined by the above-described method. It can be easily fixed by changing (Figs. 2 to 4). Since it is fixed along the vehicle bodies P and P ', no dead space is generated.

Effect of the Invention As described above, in the electric connection box of the present invention, the connection block can be attached at various angles,
Even if the destination of the automobile or the model of the automobile changes, it can be easily fixed according to the shape of the vehicle body or panel, and the cost can be reduced by reducing the number of products and making them common.
