Description

  The present invention relates to an electrical junction box having a housing body and a lid that fits so as to close an opening of the housing body.

Conventionally, for example, an electric junction box is used as a module for distributing power supplied from a power source such as an automobile battery or an alternator to each electrical component.
Such an electrical connection box accommodates an electrical / electronic component or a portion for electrically connecting the terminal fitting of the electric wire with the terminal fitting therein, and draws out the electric wire from the electric wire outlet.

  For example, Patent Document 1 describes an electrical junction box that enhances drainage performance by drainage holes in a case that is locked to a cover.

JP 2004-96968 A

  However, when connecting the terminal fittings of the two electric wires with terminal fittings through the conductive member inside the electrical junction box, the terminal fittings must be fastened to the conductive member with bolts. That is, it is necessary to fasten each terminal fitting to the conductive member with two bolts, which increases the number of parts.

In order to solve this problem, it is conceivable to directly connect the terminal fittings of the two electric wires with terminal fittings inside the electric junction box.
For example, as shown in FIG. 10 (a), the electrical connection box 100 is connected by one bolt B by overlapping the plate-like connection portions C1 formed on the terminal fittings C of the two electric wires CW with terminal fittings. Each of the electric wires CW with two terminal fittings formed in the accommodating portion 110 having the accommodating main body portion 120 that accommodates the fixed portion and the lid portion 130 that is fitted so as to close the opening 120a of the accommodating main body portion 120. It is assumed that the electric wire W is pulled out from the electric wire outlet 140 in a state where the gap between the electric wire outlet 140 and the electric wire W is sealed by the sealing member E.

  In such an electrical connection box 100, since two plate-like connection portions C1 are overlapped, a step S is generated in the two electric wire outlets 140 by the thickness of the plate-like connection portion C1. For this reason, there is a problem that the seal member E provided in one of the wire outlets 140 protrudes due to the step S, and the lid 130 cannot be assembled to the housing main body 120 (FIG. 10A). reference).

  As one method for solving this problem, the seal member E on the protruding side is adjusted to a shape that does not protrude, or the shape of the terminal fitting C1 is devised to absorb the step S (see FIG. 10B). However, there is a problem in that the number of seal members E or terminal fittings C increases, resulting in an increase in the number of parts.

  Further, as another method for solving this problem, a step S caused by the plate thickness of the plate-like connection portion C1 in which two electric wire outlets are overlapped as in the electric connection box 200 shown in FIG. The fitting-side edge surfaces 150a and 160a of the housing main body 150 and the lid portion 160 are formed on one side corresponding to the step S, while being formed at positions shifted in the overlapping direction of the plate-like connection portion C1. Although it is conceivable to change in a step shape from the electric wire outlet 140 side toward the other electric wire outlet 140 side, a portion changing in a step shape is formed in the fitting portion between the housing main body 150 and the lid portion 160. For this reason, the sealing performance of the fitting portion is lowered, and as a result, the waterproof performance may be lowered.

  The present invention has been made in view of the above, and while reducing the number of parts, the waterproof performance of each of the electric wires with two terminal fittings that electrically connect and fix the terminal fittings inside is reduced. It is an object of the present invention to provide an electrical junction box that can be pulled out from each electric wire outlet without causing it to occur.

  In order to solve the above-described problems and achieve the object, an electrical junction box according to claim 1 of the present invention is obtained by superimposing plate-like connection portions formed on each terminal fitting of two electric wires with terminal fittings. An electric wire with two terminal fittings formed in an accommodating portion having an accommodating main body portion that accommodates a portion connected and fixed by one bolt and a lid portion that fits so as to close an opening of the accommodating main body portion. An electrical connection box for drawing out an electric wire from each electric wire outlet with a gap between the electric wire outlet opening sealed with a sealing member, and the two sealing members sealing each of the electric wire outlets are the same It is a component, and the accommodating portion is formed at a position shifted in the overlapping direction of the plate-like connection portion corresponding to a step caused by the plate thickness of the plate-like connection portion where the two wire outlets are overlapped. While The fitting-side edge surface of the storage main body and the lid is gradually changed in the overlapping direction from one wire lead-out port side to the other wire lead-out port side corresponding to the step. It is characterized by.

  Moreover, in the electrical junction box according to claim 2 of the present invention, in the above invention, the housing portion is configured such that the fitting body end surface of the housing main body portion and the lid portion is connected to one of the wire outlet ports. It is characterized by changing in an inclined shape toward the other electric wire outlet side.

  Further, in the electrical junction box according to claim 3 of the present invention, in the above invention, the lid portion has a wall facing the opening corresponding to the fitting side end surface of the lid portion. It is characterized by gradually changing in the overlapping direction from the outlet side toward the other electric wire outlet side.

  The electrical connection box according to claim 1 of the present invention can connect and fix the plate-like connection portions of the two electric wires with terminal fittings by using the one bolt, and the two pieces. The seal member that is set in the wire lead-out port that pulls out each wire of the terminal-attached wire is the same component, and the fitting-side edge surfaces of the housing main body and the lid are the plate-like connection. In correspondence with the level difference caused by the plate thickness of the part, it is adapted to gradually change in the overlapping direction from the one wire lead-out port side to the other wire lead-out port side, The fitting part with the lid part can be prevented from overlapping in a stepped manner, and the sealing performance of the fitting part can be prevented from being lowered. At each other's end Fitting can be drawn from the electrical respective wires outlet without the respective wire reduces the waterproof performance of the two wire with the terminal fitting to be connected and fixed.

  In the electrical junction box according to claim 2 of the present invention, the fitting-side end surface of the housing main body and the lid is inclined from one of the wire outlets to the other of the wire outlets. Therefore, the effect of the step can be reduced as much as possible to prevent a decrease in the sealing performance of the fitting portion between the housing body and the lid, resulting in waterproof performance. Can be reliably prevented.

  In the electrical junction box according to claim 3 of the present invention, the wall facing the opening of the lid portion is gradually changed in the overlapping direction in accordance with the step, and thus is located on the lower side by the step. Since the width of the electric wire outlet side is smaller than that of the electric wire outlet side positioned on the higher side due to the step, a compact size corresponding to the step can be obtained.
