The projection 18a of the male coupler half 16a is locked in the locking hole 18b, and the lead wires 14a and 14b are electrically connected.
[0031]
Next, as shown in FIGS. 2 and 10, the lead wire coupler 15 thus fitted is disposed between the first divided cover 21 and the second divided cover 22, and the first divided cover 21. And the second divided cover 22 are combined so that the contact portions 21c and 22c of the side walls 21b and 22b overlap each other.
[0032]
At this time, when the two divided covers 21 and 22 are brought close to each other, first, the positioning columnar protrusion 25a is inserted into the insertion hole 25b, and the relative position between the first divided cover 21 and the second divided cover 22 is preliminarily adjusted. Subsequently, the first and second divided covers 21 are aligned by inserting the positioning plate-like protrusions 23 a of the first divided cover 21 into the inner side surface 23 b of the side wall 22 b of the second divided cover 22. At the same time, the hook 24a of the first divided cover 21 abuts on the engaged portion 24b of the second divided cover 22 and enters while elastically deforming, and the first divided cover 21 and the abutting portion 21c of the side wall 21b of the first divided cover 21 When the contact portion 22c of the side wall 22b of the two-divided cover 22 contacts, the hook 24a engages with the through hole 24c of the engaged portion 24b. Thereby, the 1st and 2nd division | segmentation covers 21 and 22 are integrated.
[0033]
In this state, first, since the engaging portion between the hook 24a and the engaged portion 24b cannot be touched from the outside, the engaged state cannot be released.
[0034]
Further, the first and second divided covers 21 and 22 are locked with the coupler locking portions 28a and 28b in contact with the end portion 16c of the male coupler half 16a on the lead wire 14a side. On the other hand, the stepped portion 15a of the female coupler half 16b is locked with the coupler locking portions 29a and 29b of the first and second divided covers 22 in contact with each other. Therefore, the lead wire coupler 15 accommodated in the cover member 20 is locked in a state where it cannot move in any of the lead wires 14a and 14b, and the two coupler halves 16a and 16b of the lead wire coupler 15 are separated. Is blocked.
[0035]
Further, in this state, the female coupler half 16b is accommodated in the cover member 20 with the lead wire insertion portion 15c of the lead wire 14b exposed. The entire male coupler half 16 a is accommodated in the cover member 20.

Thereafter, the metal band 19 is deformed and wound around the cover member 20 in such a state, and both ends of the metal band 19 are connected by the rivets 32, so that the cover member 20 is covered with the metal band 19, and each divided cover 21 is covered. , 22 to prevent separation. At this time, the metal strip 19 is disposed between the stoppers 31 on the outer peripheral surfaces of the first and second divided covers 21 and 22.
[0038]
According to the lead wire coupler separation preventing structure configured as described above, the first and second divided covers 21 and 22 are combined to engage the hook 24a and the engaged portion 24b. When the wire coupler 15 is accommodated in the cover member 20, the hook 24 a and the engaged portion 24 b are engaged, and the engaged state cannot be released from the outside. Therefore, the cover member 20 is connected to the first divided cover 21 and the first cover 21. It cannot be divided into two divided covers 22 and opened. At the same time, in this state, the end portion 16c of the male coupler half 16a and the step portion 15c of the female coupler half 16b are respectively locked to the coupler locking portions 28a, 28b, 29a, 29b, and the lead wires 14a, 14b cannot be taken out, and separation between the male coupler half 16a and the female coupler half 16b can be prevented. Therefore, unless the cover member 20 is destroyed, the male coupler half 16a and the female coupler half 16b cannot be separated, and separation of the lead wire coupler 15 can be reliably prevented.
[0039]
Further, since the step portion 15a is formed between the fitting portion 15b on the side surface of the female coupler half 16b and the lead wire insertion portion 15c of the lead wire 14b, the female coupler half 16b is entirely covered with a cover member. Even if not covered with 20, if only the fitting portion 15b side is covered, the step portion 15a can be locked to the coupler locking portions 29a and 29b, and separation of the female coupler half 16b can be prevented. It is. Therefore, it is easy to reduce the size of the cover member 20. Particularly, in the case of a saddle-ride type vehicle, since the space for disposing each component is small compared to other vehicles such as automobiles, it is necessary to make the cover member 20 as small as possible.
[0040]
Furthermore, since the projection 18a and the locking hole 18b of the male coupler half 16a and the female coupler half 16b are covered with the first and second divided covers 21 and 22 in the locked state, the projection 18a and The locked state of the locking hole 18b cannot be released from the outside, and the separation of the lead wire coupler 15 can be prevented more reliably.
[0041]
Further, since the metal strip 19 is wound around the outer surfaces of the first and second divided covers 21 and 22 made of synthetic resin, even if the cover member 20 is made of synthetic resin with relatively low strength, the metal strip 19 can be protected and can be made difficult to destroy.
[0042]
In addition, a stopper 31 is provided on the outer surface of the cover member 20 to prevent the metal strip 19 from coming off in the direction of the lead wires 14 a and 14 b, and the metal strip 19 is wound between the stoppers 31. Since the protruding portions of the side walls 21b and 22b of both the split covers 21 and 22 are inserted, the metal strip 19 wound around the cover member 20 cannot be shifted in the extending direction of the lead wires 14a and 14b, and the cover member 20 is Easy to protect.
[0043]
Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate. For example, in the above description, an example of a motorcycle has been described, but the present invention may be applied to other saddle-type vehicles such as a motorcycle. It is equally applicable.
[0044]
In the above description, an example in which the metal strip 19 is wound around the outer periphery of the cover member 20 has been described. However, without using the metal strip 19, the cover member 20 can sufficiently obtain the effect of preventing the lead wire coupler 15 from being separated. It is possible.
[0045]
Furthermore, in the above description, an example in which a part of the female coupler half 16b is exposed has been described. However, if the male coupler half 16a has a surface that can contact from the lead wire 14a side, It is also possible to accommodate the male and female coupler halves 16a and 16b with the cover member 20 in a state where a part of each is exposed. If there is a sufficient space for the arrangement, both the male and female coupler halves 16a and 16b may be accommodated in the cover member 20.
[0046]
【The invention's effect】
As described above in detail, according to the first aspect of the present invention, the cover member is composed of a pair of split covers that house the lead wire coupler, and one split cover is formed with an engaging portion, The other split cover is formed with an engaged portion with which the engaging portion is engaged, and the engaged state between the engaging portion and the engaged portion is configured so as not to be released from the outside. Since the coupler locking portion for locking the lead wire coupler is formed on both split covers in a state where the portion and the engaged portion are engaged, when the lead wire coupler is accommodated in the cover member, Since the engaging portion of the split cover and the engaged portion of the other split cover are engaged and the engaged state cannot be released from the outside, the cover member cannot be divided and opened. And the other coupler half is locked by the coupler locking portion, respectively. Can not be issued Ri, it is possible to reliably prevent the separation of the two coupler halves of the coupler lead wire.
In addition, since the metal strip is wound around the cover member in the engaged state of the pair of split covers, and the split strip cover is prevented from being separated by the metal strip, the synthetic resin having relatively low strength. Even if it is a property cover member, it is protected by a metal strip and can be made difficult to break.
[0047]
According to the second aspect of the present invention, the female coupler half has a step portion between the fitting portion of the male coupler half and the fixing portion of the lead wire. Since it is locked to the coupler locking portion of the split cover, if only the fitting portion side of the female coupler half is covered with a cover member, separation of both coupler halves of the lead wire coupler can be prevented. It is not necessary to cover the entire female coupler with the cover member. Therefore, it is easy to reduce the size of the cover member.
[0048]
Furthermore, according to the invention described in claim 3, the fitting engagement portion is formed in one coupler half, and the engagement engagement portion is engaged in the other coupler half. The stopper is formed, and the fitting locking part is locked to the mating locking part in a state where one and the other coupler halves are fitted, and the cover member is covered in the locked state. As a result, it is impossible to release the locking state between the fitting locking portion and the mating locking portion from the outside, and more reliably prevent separation between one coupler half and the other coupler half. can do.
