Description

Cordless handset connector for communication equipment

The present invention relates to a method of preventing twisting of a cord line connecting a main body of a communication device and a handset, and more particularly, when a cord line is connected between a body of the communication device and a handset, and the connected part is fixed, when used in a communication device. Since twisting of the cord wire occurs, the present invention relates to the manufacture of a device for preventing this.

In general, the frequent use of landline telephones can see many twisted telephone cords. The reason the phone is twisted is because the phone talks with the right hand, picking up the handset, talking with the left hand, and talking with the right hand, ending the call and putting the handset on the body of the phone.

In this case, the cord line is already rotated by 90 to 540 degrees. This multiple call causes twisting or twisting of the fixed telephone line, and the same phenomenon occurs with the interphone, handset or facsimile handset that is used at home. In addition, untwisted or twisted wires can be difficult to find the original shape and shorten the life of the wires.

The present invention is to solve the above problems, even if the handset of the communication device is rotated so that the handset itself is rotated without transmitting the rotating force to the cord line and the texture of the call to maintain the best state and the handset and the cord By providing a device of a rotating conductor between the wires to provide a method of manufacturing a handset and a cord line connecting device of a communication device to maximize the aesthetic effect of aesthetically beautiful phone and have a semi-permanent life of the cord line. There is a purpose.

In order to achieve the above object, the present invention provides a device for rotating between a handset and a cord of a communication device.

1. Inserting a ball bearing between the bushing and the shaft

2. A combination of four sets of circular conductors and insulators is fixed to the shaft.

3. Assemble the body and the pin spring conductor fixed to the body and the four sets of circular conductors to maintain tension and make the shaft rotate.

4. Assembling so that the body and the shaft cord wire is integrated by inserting the cord wire connected to the handset of the communication device inside the shaft.

5. The steps of mounting the assembled inside the handset to be integrated

6. It is installed at a certain point of the cord line to make it compatible with commonly used handset cord line. Even if the handset rotates, the cord line can be used without twisting or twisting.

Hereinafter, described in detail by the accompanying drawings as follows.

Fig. 4 is a cross-sectional view of the cord-twisting connection device to the handset of the communication device, with the handset cord wire 3 and the shaft 4 bushing 5 ball bearing 6 ball bearing support 7 circular conductors 8 One group of four circular insulators (9) and one shaft bearing ball bearing (10) being one rotor, and one group of bodies (1) and pin spring terminals (2) being one rotor. Even when the body 4 is assembled and rotated, the cord wire 4 to be rotated is a cross-sectional view showing no twisting phenomenon.

On the other hand, Figure 7 shows a diagram of a code line that is currently widely used in general, let's fix the part of Figure 7 (11, C) and rotate the part (11, D).

As a result, the portion of the cord wire 3 can be directly twisted or twisted.

To compensate for this, see FIG. 5, which is invented to be compatible with FIG. 7.

By fixing the part of Fig. 5 (11, B) and rotating the part (11, A) by the experimental method of Fig. 7, it can be seen that the cord line 3 is not twisted or twisted. In this phenomenon, Figures 1 to 5 eliminate the problems as shown in Figure 7 and look at the configuration of the device for preventing the twist of the cord line as follows.

The body 1 of FIG. 1 is a synthetic resin molding material and should be processed after molding so that the bushing 5 part of FIG. 2 can be accurately inserted and fixed to the part (A) which is circularly drilled, and the pin spring terminal (2) It is suitable as a conductor when it is used as a gold plated material in stainless steel wire 0.15 ° which can maintain constant tension at all times.

3 shows that after inserting the ball bearing 6 into the bushing 5, the ball bearing support 7 is fixed to the shaft 4, and the total of four sets of circular insulators 8 and the circular insulator 9 is fixed. The four strands of the cord 3 are inserted to make contact with the four circular conductors 8, and FIG. 2 is assembled with FIG.

In this process, the ball bearing 10 is inserted to support the center of the shaft 4 and minimize the frictional force of the rotation, and as shown in FIG. 1 and FIG.

Here, the shaft (4) and the bushing (5) ball bearings (6) ball bearing support (7) should be made of polyurethane material to minimize the friction and friction when rotating.

In this case, the handset cord line of the communication device has no kink or twist and no friction noise is transmitted to the handset, so that the call sensitivity can be maintained at the best.

As described above, the present invention uses the circular conductor on the rotating shaft to invent an anti-twisting device of the handset cord line of the communication device, thereby eliminating the discomfort that may be caused during a call, thereby maximizing efficiency and By maintaining the original state of the line, it gives aesthetical beauty, life can be used semi-permanently, and it can have the result of eliminating the inconvenience of life due to communication devices.
