[0016]
FIGS. 3 and 4 show the movable connector portion of FIGS. 1 and 2 in more detail.
[0017]
1 to 4, holes 14 a and 14 b that are movably fitted to locking projections 13 a and 13 b provided on support portions 12 a and 12 b formed integrally with the main body 5 are provided at both ends thereof. holder 15a, and 15b, the holder 15a, the pawl 16a with an elastic provided in 15b, is fixed and held by 16b, Ri housing 18 Tona accommodating the relay lead 16 painters crimped terminal portion 17, the relay The movable connectors 19a and 19b coupled to both ends of the lead wire 16 are positioned in a state where the locking projections 13a and 13b of the main body 5 and the holes 14a and 14b of the holders 15a and 15b are fitted. The switch unit is disposed at a position substantially opposite to the fixed connectors 10a and 10b. Here, the movement of the movable connectors 19a and 19b is limited by the gap amount between the locking projections 13a and 13b and the holes 14a and 14b, so that the movable connectors 19a and 19b do not fall off the main body 5. The main body 5 and the holders 15a and 15b are coupled by means such as press fitting using the elastic force of the resin of the support portions 12a and 12b of the main body. Further, on the opposite side of the support portion 12a, 12b of the main body 5 between the holders 15a, 15b, a stopper portion 20a for locking the movable connectors 19a, 19b when the switch unit is removed integrally from the main body 5. 20b is provided.
[0018]
In the present embodiment, since a digital circuit is set on the wiper switch unit 2 side, the wiper switch unit 2 is provided with an output connector 3c that outputs a signal to the vehicle side.
[0019]
In the combination switch configured as described above, connection between each switch unit and the relay connector will be described with reference to FIGS. 1, 2, 5, and 6. FIG.
[0020]
Each switch unit is positioned and held by inserting the crosspieces 6a and 6b provided in the cases 4a and 4b into the grooves 5a and 5b provided in the main body 5. When the switch unit is inserted into the main body 5 at this time, the stopper claws 8a and 8b of the cases 4a and 4b are elastically fitted to the locking walls provided on the main body 5 due to the elasticity of the U-shaped mounting knob portions 7a and 7b. At the same time, the switch unit is held on the main body 5 without any change, and at the same time, the insertion state of the movable connectors 19a and 19b and the fixed connectors 10a and 10b is held.
[0021]
Generally fixed connector 10a of the switch unit side, the position of the 10b, the body 5 and the case 4a, per 4b gentlemen, fixed connector 10a, a printed board 9a and 10b, displacement mounting position to 9b, a printed board 9a, 9b of There are variations due to factors such as displacement of the mounting positions of the cases 4a and 4b and dimensional variations of the components, and the positions do not necessarily coincide with the positions of the movable connectors 19a and 19b mounted on the main body side. However, the fixed connectors 10a and 10b according to the present invention are supported by the locking projections 13a and 13b with respect to the main body 5 and thus do not fall off, and the holes 14a and 14b of the holders 15a and 15b and the locking on the main body side. Since the projections 13a and 13b move freely and freely by the dimensional difference, by moving according to the positions of the fixed connectors 10a and 10b on each unit side, the two are finally matched to the variation. Connector mating is achieved. Further, when the switch unit is removed, the holders 15a and 15b of the relay movable connectors 19a and 19b are regulated by the stopper portions 20a and 20b of the main body 5, so that the relay movable connectors 19a and 19b are moved in the removal direction. Instead, the switch unit side fixed connectors 10a and 10b are pulled out.
[0022]
Therefore, in the movable connectors 19a and 19b of the automobile combination switch configured as described above, the connector can be surely inserted and removed without increasing the dimensional accuracy of each component and unit, and a highly reliable relay connector structure. Is realized.
[0023]
Further, at this time, as shown in FIG. 6, at least one of the fixed connector 10a, 10b on the switch unit side or the movable connector 19a, 19b for relay is uneven on each ridge portion on the surface side (insertion side) facing each other. By providing the guide portions 21a and 21b that are more than the amount by which the positions of the two are displaced, the relay movable connectors 19a and 19b can be smoothly moved by being guided by the guide portions 21a and 21b, and more reliably inserted. And can be combined.
[0024]
Incidentally, in the above embodiment, the holder 15a, 15b in the hole 14a, 14b and is provided, the locking protrusion 13a on the 5-side body is provided with the 13b, which the same effect can be reversed structure Have
[0025]
In the above embodiment, the holders 15a and 15b and the housing 18 for holding the terminals are formed as separate parts, the housing 18 is inserted into the holders 15a and 15b, and the resin claws 16a provided on the holders 15a and 15b. , 16b is integrated to prevent the housing 18 from falling off, and the movable connectors 19a, 19b are constructed. However, the housing 18 is formed by resin molding and at the same time a holder having holes 14a, 14b at both ends thereof. By forming 15a and 15b as movable connectors, it is possible to further reduce the number of parts and simplify the assembly.
[0026]
