Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention is a fastener comprising a binding band having a plurality of convex teeth formed in a simple shape, and a pair of pawl members that can engage with the convex teeth. The present invention relates to a binding tool for electric wires, etc., which is made by combining the above-mentioned fasteners with a special structure to ensure engagement with a binding band.

(Prior art and its problems) Conventionally, binding tools for electric wires, etc. have been broadly classified into
- As shown in No. 6378, a wire band having a predetermined length and having serrated teeth formed on one side thereof is integrally formed with a stopper that engages with the teeth to stop the binding band; As shown in Japanese Patent Publication No. 51-36680, there is a device in which a binding band with hook-shaped teeth formed on one side and a stopper for fixing the binding band are separate pieces.

However, the length of the cable tie required for binding differs depending on the size of the objects to be bound, such as electric wires, etc., whereas in the former case, the length of the cable tie is constant, so unnecessary band ends must be cut off. Not necessarily,
In addition to being uneconomical due to material loss, when used in automatic machines, the wasted portion of the cable tie may interfere with the operation of the machine, so the former poses problems when used in automatic machines.

In the latter case, you only need to cut off the cable ties to the required length, so there is no loss. However, when the binding band is wrapped around the object and tightened by the stopper, the opening end of the stopper is pulled in the opposite direction, so the opening of the stopper is deformed and at the same time the lock formed in the opening is pulled. The artificial claws also transform. For this reason, the state of engagement between the convex teeth of the binding band and the engaging pawl of the stopper becomes unstable, and there is a possibility that the engagement may come off or the binding holding force may be reduced.

(Technical problem of the invention) In view of the above-mentioned circumstances, the present invention combines a binding band and a stopper that are separately configured, and improves the engagement state between the binding band wound around the object to be bound and the stopper. The technical problem is to propose a binding tool for electric wires, etc., which can be held firmly and securely, and which does not cause loss.

(Means for Solving the Problems) In order to solve the above problems, a binding device for electric wires, etc. according to the present invention wraps and binds objects such as electric wires in a loop, and has a plurality of protrusions on the surface. It has an elongated binding band in which shaped teeth are formed into a loose shape, and an opening through which the binding band is inserted with the back sides of the binding band overlapped, and from one opposing wall in the opening to each of the openings. In a binding tool for electric wires, etc., which is formed by combining a pair of claw members that engage with the convex teeth of the cable band inserted therein, and a stopper that projects in a V-shape, the inner surface of the base side of the claw member is connected to the opening. A binding band inserted into the opening is formed so as to be retracted from the binding band inserted into the opening, and the other opposing wall adjacent to one opposing wall of the opening and facing each other has a binding band inserted into the opening. forming a guide groove that guides both side edges of the binding band so that the overlapping surface of the binding band is inserted along the central axis of the opening, and a guide surface of the end of the guide groove on the winding side of the binding band It is characterized in that the gap between the tips of the pair of claw members is formed to be larger than the thickness of the binding band while expanding so as to separate from each other.

(Operations and Effects of the Invention) According to the above configuration, the binding tool according to the invention includes a long binding band having a plurality of convex teeth formed in a loose shape on the surface thereof, and a binding band that is connected with the back surfaces of the binding band. a stopper having an opening through which the cables are inserted in an overlapping state, and having a pair of claw members protruding from opposing walls within the opening to engage with the convex teeth of the binding band inserted through the opening; Since it is a combination, one end of the cable tie is inserted through the opening of the stopper, then wound around the object to be bound, such as an electric wire, in a loop shape, and then the one end is inserted into the opening of the stopper in the opposite direction. Then, the convex teeth are engaged with one claw member of the stopper, and then the base side of the binding band is tightened and the convex teeth are engaged with the other claw member of the stopper, thereby binding. Cut off the unnecessary part of the cable tie that protrudes from the stopper. For subsequent binding, the cut can be used as a tip with another stopper. Therefore, the cable ties can be used effectively without waste, and mechanical bundling becomes possible.

Furthermore, since both side edges of the cable ties inserted into the opening are guided by guide grooves so that the overlapping surfaces of the cable ties are along the central axis of the opening, the cable ties are stacked with their back sides together. The convex teeth engage with both of the pawl members reliably and evenly, thereby preventing uneven engagement.

Note that during the tying work, when one end of the tying band is first inserted through the opening, the tying band is guided toward the center by the guide groove, and the space between the tips of the pair of claw members is the length of the tying band. Since it is formed larger than the thickness, the insertion operation can be performed smoothly.

Furthermore, when the cable tie inserted into the opening is strongly tightened, the cable tie is guided to the center position by the guide groove, and the inner surface of the base side of the claw member retreats relative to the cable tie inserted into the opening. Therefore, the convex teeth of the binding band do not come into contact with the base of the claw member. Therefore, the engaged state of the tip of the claw member can be maintained well.

In addition, the guide surfaces at the ends of the winding side of the cable tie in the guide groove are widened so as to separate from each other, so that after the cable tie is inserted through the stopper opening and wound around an electric wire, etc. In addition to making it easier to insert the binding band into the opening, the opening of the binding band that comes out of the opening after tying becomes larger, which reduces the tightening resistance of the binding band and allows for stronger binding. Furthermore, since the distance between the fastener and the object to be bound is close, the binding state is stable and the appearance is good.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In the figure, symbol A indicates a binding tool. This binding device A is made up of a combination of a synthetic resin binding band 1 and a stopper 2, and is used for binding electric wires and the like.

The binding band 1 is used to bind objects such as electric wires by winding them in a loop, and as shown in Fig. 2, a plurality of convex teeth 3, 3, . It is a long member.

The stopper 2, as shown in FIGS. 3 and 4,
The binding has an opening 5 large enough to allow the binding band 1 to be inserted with its back surfaces aligned and stacked, and is inserted into the opening 5 from one opposing wall 6a, 6a in the opening 5. A pair of claw members 7, 7 that engage with the opposing walls 3, 3, . . . of the band 1 are provided in a protruding V-shape.

Next, the claw members 7, 7 are attached to the opposite wall 6 of the stopper 2.
a, 6a, and engaging grooves 8, 8 are formed facing each other on the inner surface of each tip, and the gap w between the tips is larger than the thickness of the binding band 1. Further, a recess 9 is formed on the opposing inner surface on the base side of the claw member 7, thereby forming an opening 5.
It is formed so as to be retracted from the binding band 1 inserted therein.

Note that the engagement groove 8 may be configured to engage with two or more convex teeth 3 of the binding band 1. Also,
Of course, the configuration in which the base side of the claw member 7 is retracted from the binding band 1 may also be achieved by separating the guide surface of the binding band guide groove 11, which will be described later, from the inner surface of the base part of the claw member 7.

Next, one opposing wall 6a, 6a of the opening 5
The other opposing wall 6 adjacent to and facing each other
b, 6b are inserted into the opening 5 so that the overlapping surfaces of the binding band 1 are aligned with the central axis P of the opening 5 by guiding both side edges 4, 4 of the binding band 1 inserted into the opening 5, respectively. guide grooves 11, 11
is formed. The guide surfaces 11a and 11a at the ends of the guide groove 11 on the winding side of the binding band 1 are expanded so as to separate from each other.

Here, to explain how the binding device A having the above structure is used, first, one end of the binding band 1 is inserted through the opening 5 of the stopper 2, and then the electric wires 10, 10 are inserted.
. . . and then insert the above-mentioned one end into the opening 5 of the stopper 2 in the opposite direction to tighten the cable tie 1.
are inserted into the opening 5 in a state in which they are overlapped with their back surfaces, and the convex tooth 3 is inserted into the claw member 7 of one side of the stopper 2.
to the engagement groove 8 of. Thereafter, the base side of the binding band 1 is tightened and the convex teeth 3 are engaged with the engagement grooves 8 of the other claw member 7 of the stopper 2, thereby making it possible to bind the band. The unnecessary portion of the binding band 1 that protrudes from the stopper 2 is cut off. The next conclusion is
The cut can be used as a tip with another stop.

Note that the distance between the tips of the pair of claw members 7, 7 is
is formed to be larger than the thickness of the cable tie 1, so that when the cable tie 1 is first inserted from the opening 5, the convex teeth 3 are less likely to catch on the claw member 7, and are also prevented from getting caught. Since it comes off quickly, the insertion process can be done smoothly.

Further, one opposing wall 6a, 6a of the opening 5
The other opposing wall 6 adjacent to and facing each other
b, 6b include the side edges 4, 4 on both sides of the cable tie 1.
Since guide grooves 11, 11 are formed to guide the binding bands 1 so that the overlapping surfaces of the binding bands 1 are inserted along the central axis P of the opening 5, the convex shape of the binding bands 1 overlapped with their back sides together is formed. The teeth 3 are reliably and evenly engaged with both of the claw members 7, 7, and uneven engagement can be prevented.

etc., and can prevent uneven engagement.

Note that during the binding work, when first inserting one end of the binding band 1 into the opening 5, the binding band 1
is guided toward the center by guide grooves 11, 11,
Also, since the distance between the tips of the pair of claw members 7, 7 is larger than the thickness of the binding band 1,
The insertion work can be performed smoothly.

By the way, when the binding band 1 wound around the object to be bound 10 is tightened, at the opening end of the binding side of the stopper 2, the exit side and the input side of the binding band 1 are pulled in opposite directions, so that the opening In addition to transforming 5,
If the convex teeth 3, 3 come into contact with the inner surface of the base of the pawl member 7 as shown in FIG. 2 in the same way as conventional binding tools.
There is a risk that the binding band 1 may become disengaged or the holding force of the stopper 2 may be reduced. However, the binding band 1 is guided to the center position by the guide grooves 11, 11, and the inner surface of the base side of the claw members 7, 7 is connected to the binding band 1 inserted into the opening 5 by the recesses 9, 9. Since it is formed to be retracted, the convex teeth of the binding band do not come into contact with the base of the claw member. Therefore, the engaged state of the tip of the claw member can be maintained well.

Further, guide grooves 11a, 11 at the ends of the guide grooves 11, 11 on the winding side of the binding band 1
By expanding a so as to separate from each other,
The work of inserting the binding band 1 through the stopper opening 5, winding it around the electric wires 10, 10, etc., and then inserting it into the opening 5 again can be carried out easily. Furthermore, since the opening of the binding band 1 that comes out from the opening 5 after binding becomes larger, the tightening resistance of the binding band 1 is reduced, and strong binding can be achieved.
Further, since the distance between the stopper 2 and the object to be bound 10 is close, the binding state is stable and the appearance is good.
