Description of the Related Art In a vehicle, for example, an automobile, a demand for comfort during riding increases, for example, audio equipment, a navigation device, a television, and the like.
There is a tendency to increase the number of in-vehicle electrical components such as electric antennas, air conditioners, rear window heaters, seat heaters, power seats, and suspension hardness control devices. [0003] These on-vehicle electrical components are supplied with power from a wire harness or the like via an electric connection box arranged near a battery in an engine room. At this time, in the electric connection box, a fuse for preventing an excessive current from flowing when the wire harness or the like and the body are short-circuited due to some trouble, or when a load of a motor or the like breaks down, and various operation switches. In conjunction with the above, electric components such as a relay for controlling power supply to the on-vehicle electrical components are mounted. [0004] Such an electric junction box is, as shown in FIG.
Electrical components such as a relay 51, a fuse 52, and an external connection terminal 53 connected to the vehicle body-side wire harness are mounted at predetermined positions and can be combined with each other. The lower case 1 and the upper case 2, the lower case 1 and the upper case 2
And an electrically insulative wiring board 3 in which the electric wire W is arranged in a desired shape (only a part is shown in FIG. 6), and electrically connects the electric wire W and the electric component. And press-connecting terminals 3t for connecting the two. As shown in FIG. 7, a plurality of wiring grooves 3s slightly wider than the electric wires W are formed in the wiring board 3 to arrange the electric wires W into a desired shape. Board 3
Is located at a predetermined position on the outer edge of the terminal Ws of the wired electric wire W.
Is formed with a notch 3k having a size substantially equal to the diameter of the electric wire W for supporting the electric wire W. And the electric wire W is
The wire W is inserted into the wiring groove 3s and wired in a predetermined path, and the terminal end portion Ws of the electric wire W is cut near the outside of the notch 3k. [0006] The wiring work of the electric wire W is generally performed using an automatic wiring device. More specifically, the starting end of the electric wire W is inserted into a predetermined position of the wiring groove 3s by an automatic wiring device (not shown), and then the electric wire W is passed through a desired path in a so-called one-stroke manner. Are drawn out continuously from the notch 3k shown in FIG. 7, and cut around the notch 3k using a cutter (not shown) provided near the electric wire supply nozzle. Thereafter, the continuously laid wires W are cut at predetermined locations to divide them into desired circuits, and the crimping terminals 3t are driven into predetermined locations of the wires W to provide wires W for each circuit.
And electrical parts and wire harness connectors. Subsequently, as shown in FIG. 6, a lower case 1 is assembled by attaching a bus bar 4c to one side surface (a lower surface in the figure) of the wiring board 3, and an insulating plate 5 to which the bus bars 4a and 4b are attached and an upper plate. The case 2 is mounted on the other side surface (the upper surface in the figure) of the wiring board 3 and the electronic control unit 6 is mounted. Further, electrical components such as the relay 51 and the fuse 52 are mounted to complete the electrical junction box. [0008] In performing the wiring work on the wiring board 3, when the electric wire W is cut by a cutter, FIG.
As shown in FIG. 7, the electric wire W is cut while slightly projecting (for example, about 2 mm) from the notch 3k. When the wiring board 3 is assembled to the lower case 1 in a state where the electric wires W protrude from the outer edge of the wiring board 3, as shown in FIG. 8, the electric wire terminal portion Ws and the peripheral wall of the lower case 1 interfere with each other. More specifically, when the amount of protrusion of the electric wire W is long (for example, 2 mm or more), the electric wire end Ws is
The wiring board 3 and the lower case 1 cannot be assembled properly due to interference with the peripheral wall. Therefore, the operator needs an extra operation of further cutting the wire end portion Ws. On the other hand, when the protrusion amount of the electric wire W is not so long (for example, 2 mm or less), the wiring board 3 can be assembled to the lower case 1, but the electric wire end portion Ws is pushed up by the peripheral edge of the lower case 1 at the time of assembling. As a result, the wiring board 3 may be assembled to the lower case 1 in a state where the electric wire W is detached from the notch 3k. In this state, the insulating plate 5 to which the bus bar 4b is attached is mounted on the wiring board 3,
Further, when the electric connection box is completed by assembling the upper case 2 and the like and mounted on a vehicle or the like, the vibration of the vehicle or the like causes the insulation coating portion of the electric wire end portion Ws to rub against the edge of the bus bar 4b, and the insulation coating portion is eventually broken. Therefore, the conductor of the electric wire W may be short-circuited to the bus bar 4b. The above problem is particularly likely to occur when the peripheral wall of the lower case 1 is warped inward. Since the lower case 1 is generally made of resin, the peripheral wall of the lower case 1 may be warped. When the wiring board 3 is assembled to the warped lower case 1, the wiring board 3
The clearance between the peripheral edge of the wire W and the inner surface of the peripheral wall of the lower case 1 is reduced, and the terminal end portion Ws of the electric wire W easily interferes with the peripheral wall of the lower case 1. In order to prevent the above-mentioned problems, the assembling worker checks whether or not the peripheral wall of the lower case 1 is warped, and every time the wiring work is completed, the wire end portion Ws has a notch 3k.
After the wiring board 3 and the lower case 1 are assembled, the wire end Ws is notched 3k.
It was necessary to check that it was not out of the way. SUMMARY OF THE INVENTION An object of the present invention is to provide an electric junction box in which, when assembling a wiring board to an upper case or a lower case, an end portion of an electric wire laid on the wiring board does not hinder assembling or come off from the wiring board. . [0011] In order to achieve the above object, an electric junction box according to the present invention comprises a first case and a second case, which can be combined with each other, and a first case and a second case. electrically insulating circuit board that will be placed between the second case
When the wire is laid therein provided wiring board
Wiring grooves and predetermined wiring paths inserted into the wiring grooves
And an electrical connection on which predetermined electrical components are mounted.
A connection box, which is formed at a predetermined position of a peripheral portion of the wiring board or at least one of inner side surfaces of a peripheral wall of the first case or the second case, and is arranged in a wiring groove to form a wiring portion; Marginal
Wire groove that accommodates the end of the protruding wire
It is characterized in that it has an accommodating portion composed of a wide groove . Since the housing for accommodating the terminal portion of the electric wire is formed at a proper position on at least one of the wiring board and the first case or the second case, the first portion adjacent to the terminal portion of the electric wire is provided. Interference between the case or the second case and the end of the electric wire can be prevented. As a result, such interference does not hinder the assembly of the electrical junction box. Also, the end of the electric wire does not deviate from the appropriate wiring position and does not interfere with the bus bar or the like, and therefore, the bus bar and the end of the electric wire do not rub against each other due to vibration.
There is no possibility that the wire conductor is broken and the wire conductor is short-circuited. An electric junction box according to an embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the electric connection box 10 according to one embodiment of the present invention includes a lower case 11 on which a relay 51 is mounted, and an external connection terminal 53 on which a fuse 52 is mounted and which is connected to a wire harness. Upper case 12 formed
A wiring board 13 disposed between the lower case 11 and the upper case 12 and having electric wires W for small current conduction, and having electrical insulation properties; and the wiring board 13 and the upper case 12.
, And between the wiring board 13 and the lower case 11 for conducting large current.
b, 14c, an insulating plate 15 attached to the wiring board 13, an electronic unit 16 attached to the lower case 11, and the like. As shown in FIG. 2, a wiring groove 13s slightly wider than the width of the electric wire W is formed in the wiring board 13 vertically and horizontally. Then, the electric wire W is routed from the starting end accommodating portion 13r along a predetermined path of the wiring groove 13s in a one-stroke manner. In addition, the electric wire W is cut at a required position in order to form a plurality of separate circuits, and a plurality of press-contact terminals 13t are driven into predetermined positions of the electric wire W. As shown in FIG. 1, the press contact terminal 13t is electrically connected to electrical components such as a relay 51, a fuse 52, and an external connection terminal 53 via a receptacle 23. on the other hand,
The bus bars 14a, 14b, and 14c are for forming an electric circuit for conducting large current, and an insulating plate 15 is interposed between the bus bars 14a and 14b. An insulating projection (not shown) is formed on the insulating plate 15 at a predetermined position on a surface facing the wiring board 13. The insulating projections are respectively inserted and fitted to cut portions of the electric wires W laid on the wiring board 13 to ensure insulation between the circuits of the electric wires W. At a predetermined position on the periphery of the wiring board 13, FIG.
As shown in FIG. 3, a housing recess 13h for housing the wire terminal end Ws is formed. The housing recess 13h is
To be inserted mosquitoes Potter for cutting the wire W has a sufficient width X, and when cutting the wire W by a cutter,
The wire end Ws has a depth Y that does not protrude from the outer peripheral surface of the wiring board 13. The accommodation recess 13h extends on both sides in the width direction of the wiring groove 13s, and as shown in FIG.
Even if the wire end portion Ws has a bending habit, the wire end portion Ws
Can be securely accommodated. Since the electric junction box 10 is constructed as described above, after laying the electric wire W using the automatic wiring device, when cutting with a cutter, the tip of the cutter is caused to enter the recess 13h. Thus, the electric wire W can be cut in the housing recess 13h. As a result, the wire termination Ws is
Does not protrude from the outer peripheral edge. Therefore, even if the wiring board 13 is assembled to the lower case 11 after the wiring, as shown in FIG. 3, the wire end portion Ws and the peripheral wall of the lower case 11 are sufficiently separated from each other, and there is no interference between them. Further, even if the inner peripheral wall of the lower case 11 is warped inward at the time of molding, the electric wire end portion Ws does not interfere with the inner peripheral wall of the lower case 11. Therefore, when the wiring board 13 cannot be assembled to the lower case 11 or when the wiring board 13 is assembled to the lower case 11,
3 can be prevented reliably. Note that, unlike the above embodiment, the accommodation recess 1
1h may be provided on the inner surface of the peripheral wall of the lower case 11, as shown in FIG. The depth of the housing recess 11h is a depth that does not interfere with the wire end portion Ws protruding from the wiring board 13, and the depth is such that when the wiring board 13 is assembled to the lower case 11, the wire end portion Ws The depth is such that it does not interfere with the peripheral wall. By forming the housing recess 11h on the lower case 11 side in this manner, the cutter can be connected to the housing recess 13h of the wiring board 13 as in the above-described embodiment.
And it is not necessary to cut the electric wire W in the housing recess 13h, so that a relatively large cutter can be used. As shown in FIG. 5, the housing recesses 11h and 13h may be provided in both the lower case 11 and the wiring board 13, respectively. With this configuration, the housing recesses 11h, 13h
Can be substantially sufficiently large, so that interference with the lower cover 11 can be prevented even if the wire end portion Ws projects considerably as shown by a two-dot chain line in the figure. Assembling the wiring board into the upper case,
In the case of an electric connection box having a structure in which these are further assembled to the lower case, unlike the above-described embodiment, the housing recess may be formed in the upper case instead of being formed in the lower case. Thus, it is possible to prevent the wire end portion from interfering with the peripheral wall of the upper case. As described above, the electric junction box according to the present invention comprises a first case and a second case which can be combined with each other, and a first case and a second case which can be combined with each other. And an electric insulating wiring board on which the electric wires are arranged in a desired shape, and in the electric connection box on which the electric components are mounted, the electric connection box accommodates the terminal end of the electric wire and is adjacent to the terminal end of the electric wire. An accommodating portion for preventing interference between the first case or the second case and the terminal portion of the electric wire is formed on at least one of the wiring board and the first case or the second case. It is characterized by. Since the housing for accommodating the terminal end of the electric wire is formed at an appropriate position on at least one of the wiring board and the first case or the second case, the first portion adjacent to the terminal end of the electric wire is provided. Interference between the case or the second case and the end of the electric wire can be prevented. As a result, such interference does not hinder the assembly of the electrical junction box. Also, the end of the electric wire does not deviate from the appropriate wiring position and does not interfere with the bus bar or the like, and therefore, the bus bar and the end of the electric wire do not rub against each other due to vibration.
There is no possibility that the wire conductor is broken and the wire conductor is short-circuited.
