Abstract

PURPOSE:To prevent a cord from being twisted to maintain conductivity thereof, by packing, in place, connecting members connected to one side terminals of a member making cooperative rotation with a reel so that said connecting members can also make cooperative rotation and connecting their other ends to the fixed terminals of said member used for connecting related apparatuses thereto. CONSTITUTION:A reel 2 is rotatably fitted around a pole 11 projecting in the inner chamber of a package 3 and a parting board 12 is mounted in the direction of a peripheral tangent. Then, the conductive connecting members 8 are connected to a joint terminal 6 at one end of cord installed on a member 7 making cooperative rotation with the reel 2 and the other end is connected to fixed terminals 9 used for connecting related apparatuses thereto. Accordingly, in winding and unwinding work for the cord 1, the rotation of the reel 2 is transmitted to the member 7 making cooperative rotation, but the unwound amount of cord 1 is absorbed due to movement of connecting members 8, resulting in no influence on twist or direction of twist, thus proper relation of connection can be maintained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a winder for making it easier to handle long cords of electrical equipment such as telephones.

[Prior art]

Generally, equipment that uses electric wire cords or filament materials uses long cords to expand the range of movement of the equipment, but the cords get in the way and are packaged to handle long cords. Attempts have been made to store it rolled up inside the container or to use it by feeding it out.

[Problem that the invention seeks to solve]

However, in this method, kinks occur due to repeated winding and unwinding, which often causes accidents such as breakage of the connecting portion of the core wire of the cord or poor conductivity. This often occurs when the movement of the movable contact section applies repeated torsional motion to the connection point.
Conventionally, it has been considered to make sliding contact between the fixed contact and the movable contact to maintain conductivity, but even with this, there is a tendency for disconnection to occur at the point where the cord end connects to the movable contact, and the contact contact can cause noise. There were problems with communications such as sending and receiving calls.

SUMMARY OF THE INVENTION An object of the present invention is to provide a winder with a simple structure and low cost, which makes it easy to handle the cords of telephones and the like, and which accurately eliminates these conventional drawbacks.

The present invention provides: 1) A reel (2) capable of winding and feeding out cords (1) of filamentous material is rotatably provided in a package (3), and the reel (2) is equipped with a winding energy storage. A device comprising a force mechanism (4) and a locking member (5) that engages with a fixed part, wherein the terminal (6) for connecting the cord end is connected to a member (7) co-rotating with the reel (2). ), and the terminal (6)
A conductive connector (8) connected in series is loaded in a configuration that allows co-rotation, and the other end is connected to a fixed terminal (9) for connecting equipment.
This is a winder for cords such as telephones, characterized in that it is connected to a winder for cords such as telephones.

〔Example〕

To explain using an example of a telephone as shown in the figure, a reel 2 that can wind up and feed out an electric cord 1 connected to a telephone (not shown)
The package 6 is a casing in which a housing chamber 16 for the reel 2, a cord outlet 32, and a fixed terminal are formed.
It is designed as a stand with a phone mounting surface 61 on its top surface, but if necessary, it can be hung on the wall or used as a relay storage case, and can be used as a split casing or a casing that can be opened and closed. .

The reel 2 has an insertion hole 22 for the cord 1 in its winding core 2I.
The guide groove 23 for holding and fixing the cord is formed in a wave shape so that the cord can be held so that it will not be pulled out. For example, it can be connected to a screw terminal. A conductive connecting body 8, such as a metal band or a wire body that is a good electrical conductor, is attached to this terminal 6, and the co-rotating member 7 is loaded in a spiral shape so that it can co-rotate with the reel 2, and the other end is Connected to a fixed terminal 9 for connection to an electrical device, such as a safety device, the fixed terminal 9 is connected to a fixed terminal 9 for connection to an electrical device, such as a safety device, and the fixed terminal 9 prevents twisting even when the reel 2 rotates when the cord is fed out.
It is designed not to affect the

The reel 2 is rotatably fitted onto a pole 11 protruding into the inner chamber of the package 3, and if necessary, the reel provided with a spindle can be fitted into a shaft hole in the casing to make it rotatable. The reel 2 is housed in a storage chamber 16 having a cord outlet 62 in the tangential direction of the outer periphery of the reel 2.

Further, the reel 2 uses a spiral spring mainspring as a winding auxiliary force storage mechanism 4, so that the length of the cord 1 pulled out can be rewound by the spring force.
In addition, a ratchet is used as the locking member 5, and the spring member 5I
In combination with the stopper 52, a stop holding function that prevents reverse rotation and a winding function that allows idle rotation can be realized. Note that the contact pressure mechanism between the ratchet and the spring member is such that due to the engagement with the protrusion 15 and the relationship between the stopper 52 and the locking member 5, the lock is released when the cord 1 is slightly pulled out, and the reel 2 is in a free state. It is convenient to incorporate it as follows.

The connecting body 8 is a flexible conductive strip, that is, a conductive tape wrapped in a spiral shape, and one end is fixed to the terminal 6 of the co-rotating member 7 that rotates together with the reel 2. It is connected to terminal 9. This co-rotating member 7 is the ball 1
1, is connected to the winding core 21 of the reel 2 via a concave-convex engaging part or a key, and rotates together with the reel 2. If necessary, a partition plate 12 made of resin is provided so as to function as an idling plate. You can also. In this case, it also serves as a guide wall for winding the cord 1, and the electrical insulation of the connecting body 8 can be maintained, which is convenient. The connecting body 8 may be connected with a wire material such as a cord coated with or laminated with an insulating film, or a cord with enough slack, that is, the length of the cord 1 to be pulled out. It is reasonable to use the spiral belt-like body or the filamentous body from the viewpoint of shape and alignment, and it is reasonable to use the elastic body or the filamentous body with a bendable or extensible connecting body such as a coil spring. It is also possible to adopt a configuration in which the amount of the cord 1 that is fed out can be absorbed.

Furthermore, if the connecting body 8 is an insulating coating, there is no need to divide it into two stages using the partition plate 12, and the connecting body 8 can be arranged and loaded in the same space.

The reel 2 is designed so that the cord can be wound in a single line, but the reel diameter can be made smaller so that the cord can be wound twice or more.3 In the figure, 53 is a regulating piece;
The cord 14 for connecting to the rosette is the partition wall, 14+
is the spring latching part.

16 is a support shaft, and 17 is a split groove formed in the ball 11, which serves as a hook for one end of the spiral spring. Numeral 18 is a protrusion that serves as a support piece for the spring 51. Reference numeral 19 denotes a locking support step, which is formed on a stopper 52 that projects inside the package 3 and is opposed to the locking member 5 provided on the reel 2. 20 is a mounting screw hole, and 21 is a leg piece provided as necessary. 22 is a connecting screw.

In the specific example shown in FIG. 8, the package 6 is a wall-mounted package.

However, if the cord package 3 is interposed between the telephone and the rosette to which this telephone is connected, when the telephone is moved to another location and used for making and receiving calls, the cord 1 is inserted into the package 3. When it is pulled out from the bag and used and returned to its original location, it is rolled up and stored in the glue roll 2 in the package 3 and used in an orderly manner.

In this winding and unwinding operation, 20 rotations of the reel are transmitted to the co-rotating member 7, but the movement of the connecting body 8 absorbs the amount of the cord 1 being fed out, and the effect of twisting or twisting direction on the fixed terminal 9 toward the rosette side. This allows for proper connection relationships to be maintained.

〔Effect of the invention〕

The present invention makes it easy to handle long electric cords, allows the cords to be neatly arranged without getting in the way or making them look unsightly, and has a lead wire connecting portion that is movable for winding and unwinding the cords. Since there is no twisting effect, it can be used safely for a long period of time without causing disconnection accidents or poor conductivity, and the connection can be maintained under stable conditions without the risk of communication noise, making maintenance and security extremely simple. It has the above effect.
