The jig for supporting setting electric wires 1 according to the embodiment of the present invention, for example, is used when the electric wires W are set on the electric wire holder 130 which is assembled into the vehicle indoor lamp 100.
First, the construction of the vehicle indoor lamp 100 is described, and then the jig for supporting setting electric wires 1 is described.
The vehicle indoor lamp 100 includes the lens 110, a lighting function portion 120, and the housing 140 which is used as a base of the vehicle indoor lamp 100 and to which the lens 110 and the lighting function portion 120 are assembled.
The lens 110 is a board-like member made of light-permeable material, collects light emitted from bulbs 123 of the lighting function portion 120, and allows the light to pass to the outside of the housing 140.
The lighting function portion 120 is a function portion of the vehicle indoor lamp 100, and includes a bus bar 121 , a switch operation portion 122, the bulbs 123 and an electric wire holder 130.
The bus bar 121 includes power supply terminals 121a and four press contact terminals 121b which have press contact blades 121 c to connect the electric wires W.
In this embodiment, it is exemplified that the number of the electric wires W is four, but the number of the electric wires W is not limited to four. The number of the press contact terminals 121b is also not limited, and is set according to the number of the electric wires W.
The switch operation portion 122 is an operation portion for switching ON/OFF the bulbs 123, and includes three switches 122a to switch among three modes. The switches 122a are accommodated in the housing 140. The switch operation portion 122 is connected to the power supply terminals 121a of the bus bar 121 through contacts 122b so that the bulbs 123 may be electrified.
In order to press-contact part of the four electric wires W to the press contact terminals 121b which are provided in the housing 140, the electric wire holder 130, as a portion separate from the housing 140, holds part of the four electric wires W, and is assembled while pivoting around rotation shafts 131 a which are supported by a rotation support portion 141 a.
In particular, in the electric wire holder 130, as shown in Figs. 3 to 5, the upper holding portion 131 and the lower holding portion 132 are coupled through a joint 133 which may be bent. While the joint 133 is bent, the plurality of electric wires W are sandwiched between the upper holding portion 131 and the lower holding portion 132 so that the four electric wires W are held.
The upper holding portion 131 , as an electric wire holding portion, includes the rotation shafts 131a, four electric wire retention grooves 131c which are aligned on an electric wire attached face 131b in order to hold the four electric wires W, and a plurality of electric wire retention protrusions 131e which are projected so that part of the upper ends of groove faces 13 I d of the electric wire retention grooves 131 c are extended upwards to make it difficult for the electric wires W to move away from the electric wire retention grooves 131c, and which are aligned in the direction the electric wires W are arranged. Adjacent projected upper end portions 13 If of the electric wire retention protrusions 13 l e become accepting portions for the electric wires. The electric wire holder in this embodiment is so provided that the electric wire retention protrusions 13 le are aligned in the direction the electric wires W are arranged at two end portions of the electric wire retention grooves 131c.
The rotation shafts 131a have a cylindrical shape which has a semicircular cross-section, and are provided near an end portion of the upper holding portion 131.
The lower holding portion 132 has a plurality of lower holding portion side electric wire retention grooves 132a which are formed to fit with the electric wire retention grooves 131c, when the joint 133 is bent so that the lower holding portion is overlaid on the upper holding portion 131 , to hold the electric wires W, and a press contact blade penetrating portion 132b which is formed so that the lower holding portion 132 is penetrated when the press contact blades 121 c press-contact the part where the electric wires are held in the electric wire holder 130.
The housing 140 includes the electric wire holder attached portion 141 which becomes a portion where the electric wire holder 130 is assembled.
As shown in Fig. 2, the electric wire holder attached portion 141 has the rotation support portion 141a which rotatably supports the rotation shafts 131 a of the electric wire holder 130, and a lock portion 141b which abuts with the electric wire holder 130 to fix the electric wire holder 130 at an assembled position.
Next, the jig for supporting setting electric wires 1 is described.
As shown in Figs. 6 and 7, the jig for supporting setting electric wires 1 includes a positioning platform 10 where the positions of the upper holding portion 131 of the electric wire holder 130 and an electric wire guide portion 30 to be described below are fixed, a tension adjusting portion 20 which adjusts the tension of the electric wires W, and the electric wire guide portion 30 which guides the four electric wires W to the accepting portions 13 l g of the electric wire holder 130.
The positioning platform 10 has an electric wire holder set portion 11 which includes openings, steps and the like which are formed in accordance with the external shape of the electric wire holder 130 to fix the electric wire holder 130 at a predetermined position on the positioning platform 10. The electric wire holder 130 is fixed between a first electric wire guide portion 31 and a second electric wire guide portion 32 to be described below in a state that the upper holding portion 131 is not overlaid on the lower holding portion 132 and the electric wire retention protrusions 13 le of the upper holding portion 131 face upwards.
The tension adjusting portion 20 adjusts the tension of the electric wires W so that the four electric wires W are easily guided to the accepting portions 13 lg by the electric wire guide portion 30.
The tension adjusting portion 20 has columnar protrusions 20a which are spaced and raised at six positions on the positioning platform 10. The tension of the electric wires W is adjusted by bending the electric wires W around the columnar protrusions 20a.
The electric wire guide portion 30 has a first electric wire guide portion 3 1 and a second electric wire guide portion 32 which are arranged to sandwich the upper holding portion 131 of the electric wire holder 130, which is set on the positioning platform 10, and face each other.
The first electric wire guide portion 31 and the second electric wire guide portion 32 have the same shape, and each has a plate shaped guide base part 33 and five guide protrusion pieces 34.
The plate shaped guide base parts 33 are hoard-like parts which are arranged near the upper holding portion 131 of the electric wire holder 130 and along the direction the four electric wires W.
The five guide protrusion pieces 34 are projected from the upper edge face 33a of the plate shaped guide base part 33, and are projected so that the areas around base end portions 34a, when viewed from the direction perpendicular to the direction the four electric wires W are arranged, overlap with the electric wire retention protrusions 131e.
The guide protrusion pieces 34 are so formed that the base end portions 34a are located below the accepting portions 13 l g, the distance between adjacent guide protrusion pieces 34 at upper end portions 34b is larger than the distance between adjacent guide protrusion pieces 34 at the base end portions 34a, and the upper end portions 34b are extended to positions above the projected upper end portions 131 f of the electric wire retention protrusions 13 le.
With such an electric wire guide portion 30, when the electric wires W are set on the electric wire holder 130, the electric wires W are inserted between the adjacent guide protrusion pieces 34 of the first electric wire guide portion 31 and the second electric wire guide portion 32 respectively, and are guided to the accepting portions 13 l g by the guide protrusion pieces 34 of the first electric wire guide portion 31 and the second electric wire guide portion 32.
Next, a procedure of setting the four electric wires W into the electric wire holder 130 is described by using Figs. 1 1A to 13B. Figs. 1 1A to 13B are figures which show the procedure of setting the four electric wires W into the electric wire holder 130.
First, an operator sets the electric wire holder 130 on the positioning platform 10 (refer to Figs. 11A and 1 IB). Thereby, the upper holding portion 131 of the electric wire holder 130 is fixed between the first electric wire guide portion 31 and the second electric wire guide portion 32 in a state that the electric wires W can be set into the accepting portions 131 g from above.
Then the operator draws the four electric wires W around the columnar protrusions 20a, and inserts the electric wires W between the guide protrusion pieces 34 of the first electric wire guide portion 31 and the second electric wire guide portion 32 (refer to Figs. 12A and 12B). For the first electric wire guide portion 31 and the second electric wire guide portion 32, the distance between the adjacent guide protrusion pieces 34 at the upper end portions 34b is larger than the distance between the adjacent guide protrusion pieces 34 at the base end portions 34a. That is, the distance between the upper end portions 34b of the guide protrusion pieces 34 is wider than the distance between the electric wire retention protrusions 13 l e at the accepting portions 13 l g. Therefore, the electric wires W are easily inserted between the adjacent guide protrusion pieces 34. Because the base end portions 34a of the guide protrusion pieces 34 are formed at positions below the accepting portions 131g, the electric wires W are guided to the accepting portions 131 g by the guide protrusion pieces 34.
Then, the operator folds the lower holding portion 132 of the electric wire holder 130 towards the side of the upper holding portion 131 to sandwich the four electric wires W (refer to Figs. 13A and 13B). Thereby, the operation of setting the four electric wires W in the electric wire holder 130 is completed. That is, the four electric wires W are partly fitted in the electric wire retention grooves 131c, and are aligned and held on the electric wire attached face 131b of the upper holding portion 131.
When the four electric wires W which are partly held by the electric wire holder 130 are connected to the press contact terminals 121b, the electric wire holder 130 is assembled to the housing 140 as shown in Figs. 14A to 14C. Figs. 14A to 14C are figures which show a procedure of connecting the four electric wires W which are partly held by the electric wire holder 130 to the press contact terminals 121b.
In particular, the operator sets the rotation shafts 131 a of the electric wire holder 130 on the rotation support portion 141a of the housing 140 (refer to Fig. 14 A), and then makes the electric wire holder 130 to be pivoted around the rotation shafts 131 a (refer to Fig. 14B) and fixed to the housing 140 by the lock portion 141b at an assembled position of the electric wire holder 130 (refer to Fig. 14C). Thereby, the electric wires W held by the electric wire holder 130 are press-contacted to the press contact terminals 121b.
In the jig for supporting setting electric wires 1 according to the embodiment of the present invention, the plurality of guide protrusion pieces 34 are so formed that the base end portions 34a are. located below the accepting portions 13 l g, the distance between adjacent guide protrusion pieces 34 at the upper end portions 34b is larger than the distance between adjacent guide protrusion pieces 34 at the base end portions 34a, and the upper end portions 34b are extended to positions above the projected upper end portions 13 I f of the electric wire retention protrusions 13 l e. Thus, the distance between the upper end portions 34b of the guide protrusion pieces 34 is wider than the distance between the electric wire retention protrusions 13 l e at the accepting portions 131 g. Therefore, the electric wires W is easily inserted between the adjacent guide protrusion pieces 34, and the electric wires W are easily guided to the accepting portions 131g by the guide protrusion pieces 34. As a result, the plurality of electric wires W is easily set into the electric wire retention grooves 131 c respectively even if the plurality of electric wire retention grooves 131c are aligned with narrow pitches.
In the jig for supporting setting electric wires 1 according to the embodiment of the present invention, the electric wire guide portion 30 is provided in pairs so that the upper holding portion 131 , which is used as the electric wire holding part, is sandwiched in the extending direction of the electric wires W, and the plate shaped guide base parts 33 of the first electric wire guide portion 31 and the second electric wire guide portion 32 face each other. Thus, the electric wires W is supported in two places that are spaced, and it becomes easier to guide the four electric wires W in an aligned state. As a result, with the jig for supporting setting electric wires 1 , the operation of setting the four electric wires W in the upper holding portion 131 is performed more easily.
Moreover, with the jig for supporting setting electric wires 1 according to the embodiment of the present invention, an operation of positioning the upper holding portion 131 and the electric wire guide portion 30 is not necessary. Therefore, with the jig for supporting setting electric wires 1 , the operation of setting the four electric wires W in the upper holding portion 131 is performed more easily.
With the jig for supporting setting electric wires 1 according to the embodiment of the present invention, the electric wires W, whose tension is adjusted by the tension adjusting portion 20, is guided to the accepting portions 13 l g by the guide protrusion pieces 34. Therefore, with the jig for supporting setting electric wires 1 , the operation of setting the four electric wires W in the upper holding portion 131 is performed more easily.
