Abstract

PROBLEM TO BE SOLVED: To increase the contact pressure of a watertight sealing member, bring the watertight sealing member into contact with the opening of a panel with the uniform contact pressure and improve the watertightness of the opening by a method wherein an annular rib is formed on the watertight sealing member. SOLUTION: An annular rib 18 is formed on a watertight ring 17 which is brought into contact with the other side surface of a panel 15. When a reverse retainer 14 is retained with the panel 15 so as not to fall off, a contact member 16 is brought into contact with the other side surface with the watertight ring 17 therebetween to increase the retention force of the reverse retainer 14 and the watertightness of the opening 15a of the panel 15 is maintained by the watertight ring 17. With this constitution, the annular rib 18 is brought into line contact with the other side surface of the panel 15 to increase the contact pressure of the watertight ring 17 and the watertight ring 17 is brought into contact with the panel 15 with the uniform contact pressure. As a result, the watertightness of the opening 15a of the panel 15 can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding member of a wire bundle, and more particularly, to a binding member of a wire bundle that binds a wire bundle such as a wire harness mounted on a panel of a vehicle body or an electric device.

[0002]

2. Description of the Related Art In general, it is known to use a binding band or the like as a binding member for binding and fixing a wire rod bundle such as a wire harness to a panel of a vehicle body or an electric device.
As the binding band, for example, a band as shown in FIG. 2 is known. In FIG. 2, reference numeral 1 denotes a binding band. The binding band 1 has a band member 3 wound around a wire harness 2, and a saw-tooth uneven portion 3a is formed in a predetermined region in the longitudinal direction of the band member 3. ing. A check locking member 4 is provided upright at a predetermined position of the band member 3, and the check locking member 4 is inserted through an opening 5a of a panel 5 of a vehicle body, an electric device, or the like. The distal ends 4a and 4b of the arm-shaped members of the locking body 4 are retained and locked to one side surface of the panel 5.

[0003] A contact member 6 is provided on the bottom of the check locking member 4.
A flat watertight ring 7 is provided between the contact member 6 and the distal ends 4a and 4b of the arm-shaped members of the non-return locking body 4, and the watertight ring 7 is located at the center. Is inserted from the top of the non-return locking member 4 so as to be interposed between the contact member 6 and the tip portions 4a and 4b of the arm-shaped members of the non-return locking member 4, The engagement with the distal end portions 4a and 4b of the arm-shaped members of the check locking body 4 prevents the binding member 1 from falling out of the binding band 1.

The contact member 6 is brought into contact with the other side surface of the panel 5 through the watertight ring 7 when the check locking member 4 is locked to the panel 5 so as not to come off. Body 4
And the watertightness of the opening 5 a of the panel 5 is maintained by the watertight ring 7.

[0005]

However, in such a conventional binding member of a wire bundle, since the flat watertight ring 7 is in surface contact with the other side surface of the panel 5, the contact pressure becomes uniform. There was a possibility that the liquid-tightness of the opening 5a could not be sufficiently maintained. Therefore, an object of the present invention is to provide a binding band that can sufficiently seal an opening of a panel with a sealing member.

[0006]

According to the first aspect of the present invention,
In order to solve the above-mentioned problem, a holding member for holding a wire rod bundle, and a non-return lock that is erected at a predetermined position of the holding member and can be locked to one side surface of the mating member through an opening of the mating member Body, a plate-shaped sealing member that is inserted into the non-return locking body and is prevented from falling out of the non-return locking body, and another side surface of a mating member provided at the bottom of the non-return locking body And a contact member that abuts on the sealing member with the sealing member to seal the opening of the counterpart member with the sealing member, wherein the sealing member is provided with an annular rib. Features.

In this case, since the annular rib makes line contact with the other side surface of the panel, the contact pressure of the sealing member can be increased, and the sealing member can be brought into contact with a uniform contact pressure. Hermeticity can be improved.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing one embodiment of a binding member of a wire bundle according to the present invention. First, the configuration will be described. In FIG. 1, reference numeral 11 denotes a binding band serving as a binding member. The binding band 11 has a band member 13 serving as a holding member wound around a wire bundle such as a wire harness 12, and a longitudinal direction of the band member 13. A saw-tooth uneven portion (not shown) is formed in the predetermined region.

At a predetermined position of the band member 13, a non-return locking member 14 is provided upright. The non-return locking member 14 is an opening of a panel (counter member) 15 of a vehicle body, an electric device or the like. 15a, the distal end portion 14a of the arm-shaped member of the check locking member 14,
14b is retained and locked on one side of the panel 15. Further, a dish-shaped contact member 16 is provided at the bottom of the non-return locking member 14, and the contact member 16 and the non-return locking member 14 are provided.
A flat dish-shaped watertight ring (sealing member) 17 is interposed between the tip portions 14a and 14b of the arm-shaped members. The watertight ring 17 has an opening 17a provided at the center thereof,
By being inserted from the top of 14, it is interposed between the abutting member 16 and the tip portions 14 a and 14 b of the arm members of the check locking member 14, and the tip of the arm member of the check locking member 14 is Parts 14a, 14b
Is prevented from falling out of the binding band 11.

An annular rib 18 is formed on the watertight ring 17, and the annular rib 18 comes into contact with the other side surface of the panel 15. Further, when the non-return locking member 14 is locked to the panel 15 so as not to come off, the abutting member 16 comes into contact with the other side surface of the panel 15 via the watertight ring 17 so as to be non-return. The locking force of the locking body 14 is increased, and the watertightness of the opening 15a of the panel 15 is maintained by the watertight ring 16.

An engaging member is provided at one end of the band member 13.
When the other end of the band member 13 is inserted in a state in which the wire harness 12 is wound around the band member 13, the locking claw provided inside the engagement member 19 has a saw-tooth uneven portion. , The band member 13 is positioned and fixed, and the function of holding the wire harness 12 is provided.
In the present embodiment, since the annular rib 18 is provided on the watertight ring 17, the annular rib 18 can be brought into line contact with the other side surface of the panel 15, so that the contact pressure of the watertight ring 17 can be increased and uniform contact can be achieved. The watertight ring 17 can be brought into contact with the pressure. As a result, the tightness of the opening 15a of the panel 15 can be improved.

In the present embodiment, the band member 13 is employed as the holding member. However, the present invention is not limited to this, and a plate-like member wound with a tape together with the wire harness 12 may be used.

[0013]

According to the present invention, since the annular rib makes line contact with the other side of the panel, the contact pressure of the sealing member can be increased and the sealing member can be brought into contact with a uniform contact pressure. The tightness of the opening of the panel can be improved.
