Description

Description: TECHNICAL FIELD The present invention relates to a winding core for winding a tail cord with a terminal connector for an elevator.

[Prior Art; Problems to be Solved by the Invention]

A tail cord of an elevator is a flat cord formed by arranging a large number of insulated wires in which a stranded wire conductor made of a thin wire is coated with an insulating coating and using a flexible flat sheath. This is used by connecting one end to an elevator cage and terminating the other end to a junction box provided on a wall inside the elevator shaft so as to hang down in a substantially U-shaped manner. To facilitate termination of multiple insulated wires, the tail cord ends are stripped of the flat sheath to expose multiple insulated wires and each insulated wire is spliced to a terminal connector that houses multiple terminals. It is prepared in advance as equipped with a terminal connector.

Since the tail cord with terminal connector has a flat shape and therefore has a directionality to bending, it is spirally wound around the flat surface as a winding surface and is shipped.

Conventionally, the tail cord with the terminal connector wound as described above is provided for the above-mentioned laying while being pulled up from the winding start end side, but the cord itself is not twisted every time one roll is pulled up. In addition, the stranded wire conductor made of thin wires may be broken.

The problem of the above-mentioned twist is corrected by rotating the tail cord itself by the amount of the twist. However, since the tail cord is hung from the elevator room and laid in a predetermined manner, the terminal connector on the lower end side of the cord may be swung around each time the cord is rotationally corrected, and the tail cord may be damaged by colliding with the shaft wall. was there.

By the way, in general, a drum including a winding drum having flanges at both ends is used to wind a flat-shaped cord, and the flat cord is spirally wound on the winding drum with the flat surface as the winding surface. It was wrapped (radial winding).
This one does not twist the cord itself by unwinding the flat cord from the end of the winding, but in the conventional drum of this kind, if the cord with the terminal connector is simply wound up, When the terminal connector on the winding start side is projected onto the winding cylinder, the cord wound on it may be subjected to excessive bending stress, which may damage the cord.

In order to provide a conventional metal drum in which a tail cord with a terminal connector can be easily wound, a complicated and special drum structure is required, and the manufacturing cost is high and it is difficult to apply. Further, the drum has a large installation area and a large work space, and is not suitable for carrying into a narrow elevator room and feeding out a tail cord.

Therefore, the present inventor previously proposed a packing device for a tail cord with a terminal connector. (Japanese Patent Application No. 2-13129
No. 2, Japanese Patent Application No. 2-140374) FIG. 3 and FIG. 4 show an example of a packing apparatus according to the above-mentioned prior proposal example.
And a box body 2 made of corrugated board and a shaft body 3. That is, the tail cord winding unit 5 has the tail cord 4 spirally wound around the outer peripheral edge of the winding core 1 formed by stacking a plurality of corrugated cardboard pieces cut in a donut shape. The terminal connector 41 on the start side is set in a notch-shaped groove formed in the outer peripheral edge of the winding core 1 so as to be dropped.

Tail cord winding unit 5 formed in this way
Is a hollow tube 32 such as a paper tube that serves as an element of the shaft body 3 on the core 1.
It is stored in the thin box body 2 in a state where it is attached to skewers. Then, by inserting the core shaft 31 which is another element of the shaft body 3 into the hollow tube 32 through the hole 23a formed at the center of the side walls 21 of the box body 2 facing each other, the box body is inserted. The tail cord winding unit 5 is pivotally supported with respect to 2.

The core shaft 31 includes two hat-shaped members 31a, 31 made of plastic.
It is made of a combination of a and by inserting the flange until it comes into contact with the side wall of the box body 2, both end faces with holes come into contact with each other,
The end faces are tightly bound to each other by, for example, a plastic band so as to be fixed to the box body.

The hollow tube 32 is fitted so as to straddle the joints of the hat-shaped member 31a so as to prevent corner breakage of the joints.

When the assembly is completed as above, the box 2 is covered with a lid piece.
Complete the packing with the cover of 23b.

According to the packing device configured as described above, since it becomes a thin box body, it does not take up space even if it is carried into the elevator room where the cable is installed, and again, the lid piece 23b is opened and the winding is completed. By pulling out from the terminal connector 42 on the end side, the spiral tail cord is unwound while the winding core 1 rotates about the hollow tube 32 of the shaft body 3, and a predetermined feeding is performed without twisting. be able to.

By the way, in such winding, the terminal connector on the winding start side is merely set in the groove of the winding core 1 by dropping it, and the tail cord wound around the terminal connector is wound up to carelessly jump to the outside of the winding core 1. I was trying not to.

However, if the terminal connector is simply dropped into the groove as described above, the terminal connector protrudes from the groove and comes into contact with the inner surface of the box body 2. When the tail cord is pulled out and the winding core 1 is rotated in this state, , The terminal connector 42 rubs the inner surface of the box body 2, which prevents the winding core from rotating, and the tail cord pulled out from the box body is forcibly pulled out, and the tail cord itself and the exposed insulated wire and The connection with the terminal connector could be damaged.

Depending on the customer's specifications, the terminal connector may have a smaller size than the groove of the winding core.In that case, the movement of the terminal connector in the groove of the winding core becomes active and the terminal connector is exposed. The insulated wire itself and the connecting portion between the insulated wire and the terminal connector may be damaged.

The present invention has been made in view of the above-mentioned circumstances, and can stably store the terminal connector on the winding start side without using any special means. There is a primary purpose in providing.

Further, a second object of the present invention is that even if the size of the terminal connector is changed due to the specification change, the terminal connector accommodating portion corresponding thereto can be formed without using a special third member. It is to provide a core of a tail cord with a connector.

[Means for Solving the Problems]

A solution to achieve the first object of the present invention is to make a laminated body of a plurality of flat plate donut-shaped members made of fixed corrugated cardboard, and use the outer peripheral edge of the member as a winding surface of the tail cord. , All of the flat-plate donut-shaped members that are stacked together have the same shape, and each flat-plate donut-shaped member is
An inwardly-depressed portion is formed at the outer peripheral edge that is the winding surface of the cord, and the depressed portion of at least one flat plate donut-shaped member on the outer side is a circle with respect to the depressed portions of the other flat plate donut-shaped members. The position is shifted in the circumferential direction, and the space surrounded by the concave surface of the recessed portion due to the other flat plate donut-shaped member and the side surface of the outer flat plate donut-shaped member serves as a receiving portion for the terminal connector, and The flat plate donut-shaped member and the outer flat plate donut-shaped member are arranged such that a portion having an outer peripheral edge serving as a tail cord winding surface is positioned in parallel with the other depressed portion. Located on the core of the tail cord with terminal connector.

Further, a solution means for achieving the second object of the present invention is a laminated body of a plurality of flat plate donut-shaped members made of corrugated board,
The outer peripheral edge of the member is used as a winding surface of the tail cord, and a plurality of flat plate donut-shaped members to be laminated are:
The flat plate donut-shaped member having a recessed portion on the outer peripheral edge serving as the tail cord winding surface and the flat plate donut-shaped member serving as the disc body are combined with the flat plate donut-shaped member serving as the disc body on the outside, and the one flat plate The space surrounded by the concave surface of the depressed portion formed by the donut-shaped member and the side surface of the outer flat plate donut-shaped member serves as a housing portion for the terminal connector, and also serves as the tail cord winding surface of the outer flat-plate donut-shaped member. A core of a tail cord with a terminal connector is characterized in that a portion having a peripheral edge is arranged in parallel with a depressed portion of one flat plate donut-shaped member.

[Embodiment] FIGS. 1 (a), (b), (c) and (d) are preferred embodiments embodied as a winding core that achieves the first and second objects of the present invention.

The winding core 10 of this embodiment is a laminated body in which four flat plate donut-shaped members 11, 12, 13, 14 obtained by cutting a corrugated board are stacked and integrated with an adhesive or the like.

Each of the flat plate donut-shaped members 11, 12, 13, 14 has the same shape, and forms an inwardly depressed portion 15 at the outer peripheral edge which is the winding surface of the tail cord. The depressed portion 15 is an outer peripheral edge portion 16 which becomes a tail cord winding surface.
Is gradually cut deeper inward from, and when it reaches a certain depth, a portion 15a is formed which is raised at a right angle to the outer peripheral edge portion 16.

Then, the two flat plate donut-shaped members 11 and 14 on both outer sides of the flat plate donut-shaped members are aligned so that the recessed portions 15 are located at the positions corresponding to the rotational direction,
The two middle flat plate donut-shaped members 12 and 13 are provided on both outer flat plate donut-shaped members 11 and 14 with the depressed portion 15 therebetween.
They are aligned so as to coincide with each other at a position shifted by 180 ° in the circumferential direction with respect to the depressed portion 15 in.

Therefore, the recessed portions 15 of the outer flat plate donut-shaped members 11 and 14 are located on both sides of the portion having the outer peripheral edge 16 which is the cord winding surface of the middle flat plate donut-shaped members 12 and 13, and the tail cords. I try not to hinder the winding. On the other hand, the depressed portions 15 of the middle flat plate donut-shaped members 12 and 13 are formed by the flat plate donut-shaped members 11 and 14 on both outer sides.
Is located between the portions having the outer peripheral edge 16 which is the cord winding surface. This intermediate flat plate donut-shaped member 12, 13
The space surrounded by the concave surface of the recessed portion 15 and the side surfaces of the flat plate donut-shaped members 11 and 14 having the cord winding surface on both outer sides serves as a receiving portion for the terminal connector.

Now, according to the core of the present embodiment configured as described above,
At the terminal connector accommodating portion set in the depressed portion 15 of the flat plate donut-shaped members 12 and 13, the tail cord 4
The tail cord 4 is accommodated on the winding start side and the tail cord 4 is wound around the tail cord winding surface which is continuous all around by the outer peripheral edges 16 of the middle and outer flat donut-shaped members 11, 12, 13, 14.

Then, in a state in which a hollow tube 32 such as a paper tube which is one element of the shaft body is inserted in the lateral hole 17 formed at the center of the winding core, the hollow tube 32 is inserted into the box body 2 made of corrugated cardboard and the box body 2 A core shaft 31 penetrating the side wall is inserted into the hollow tube 31 and is rotatably supported in the box body.

Now, when the tail cord is pulled out from the winding end side, the winding core is rotated together with the tail cord, but the terminal connector 41 on the winding start side is boxed by the side surfaces of the flat plate donut-shaped members 11 and 14 on both outer sides. Since it is set in the recessed portion 15 of the intermediate flat plate donut-shaped member 12, 13 in a state of being separated from the side wall of the body 2, the rotation of the winding core causes the terminal connector 41 to contact the inner surface of the box body 2. There is no risk of damaging the insulated wire 4a itself exposed at the winding start end side of the tail cord 4 and the connecting portion between the insulated wire and the terminal connector 41.

In this embodiment, the terminal connector 41 is accommodated in a state in which the direction of the terminal cord 41 is changed by 90 degrees with respect to the winding of the tail cord 4,
In that case, some twist is applied to the exposed insulated wire 4a, but this degree of twist does not damage the insulated wire 4a itself and is performed within an allowable range.

The size of the terminal connector 41 may be changed by changing the specifications. For example, when a terminal connector having a size larger than the terminal connector 41 accommodated as described above is used, the flat plate donut-shaped members 11, 1 on both outer sides are used.
One of the members 4 is a flat plate donut-shaped member 12,
By laminating and stacking in accordance with 13, to form a wider terminal connector accommodating portion that provides a wall beside the recessed portion 15 of the other member only,
Allows the accommodation of large terminal connectors. In this case, one of the main terminal connectors is exposed to the inner surface of the box body 2, but the other terminal member is supported by the wall of the outer member. It is unlikely that the problem of damaging the exposed insulated wire by vigorously contacting the inner surface of the will occur.

The size change of the terminal connector accommodating portion can be dealt with by increasing or decreasing the number of stacked flat plate donut-shaped members.

FIG. 2 shows an embodiment embodied as a winding core that achieves the first object of the present invention. That is, in the winding core of this embodiment, three flat plate donut-shaped members 111, 112, 113 having a depressed portion 150 at the outer peripheral edge which is the tail cord winding surface are laminated so that the depressed portions are aligned with each other. In addition, the flat plate donut-shaped member 114, which is a disk body, is laminated on one outer side of the flat plate donut-shaped member 114.
The side wall of the portion having the outer peripheral edge serving as the cord winding surface provides a wall at one side opening of the recessed portion 150, thereby setting the accommodating portion of the terminal connector.
When the terminal connector is set in the recessed portion, it is supported laterally by the wall portion of the flat plate donut-shaped member 114 laminated on the outside, and the same protection as described above can be achieved.

The flat plate donut-shaped member 114 serving as a disk is not limited to one side, and may be laminated on both outer sides.

[Operation of the invention; Effect]

As can be understood from the above description, according to the core of the tail cord with terminal connector of the present invention, the terminal connector to be housed in the depressed portion of at least the middle flat plate donut-shaped member among the plurality of flat plate donut-shaped members. Is supported by the side wall of the outer flat plate donut-shaped member, the insulated wire itself and the insulated wire exposed at the end of the tail cord are rubbed against the side wall of the box body to be housed after winding the tail cord. There is no danger of damaging the connection between the terminal connector and the terminal connector, and there is no problem of the tail cord being damaged when it is pulled out. Therefore, the first object of the present invention is achieved.

Further, according to the present invention, it is possible to provide the above-mentioned predetermined terminal connector stable accommodating core by a combination of flat donut-shaped members having the same shape, thereby achieving the second object.

Furthermore, since the outer peripheral edge of the outer flat plate donut-shaped member is located in parallel with the recessed portion of the flat plate donut-shaped member used for accommodating the terminal connector, even if the recessed portion is provided, the tail cord winding is hindered. It is possible to wind smoothly without coming.
