Try to extend the life of the connection cord.

[Industrial application field]

TECHNICAL FIELD The present invention relates to a connecting device with a rotating mechanism used for connecting connection cords of various terminal devices.

In recent years, curl cords have become widely used as connection cords for communication equipment such as telephones and radios, and OA terminal equipment such as personal computers and word processors. ) parts are used in different conditions, twisting and tangling may occur and hinder operation, and there is a concern that the lifespan of the connection cord will be shortened if the connection cord is used forcibly in this condition. There is a strong demand for a connecting machine with a rotating mechanism that can easily eliminate twists and entanglements.

[Conventional technology]

FIG. 3 is a diagram illustrating an example of mounting a conventional connection cord on a telephone set (al is a perspective view, and (b) is a perspective view of the main part of the cord twisted).

In the figure, the telephone body 1 and the handset 2 are connected by a curl cord 3, and the connection part of the curl cord 3 with the handset 2 is made of rubber or the like. The phone body 1 is connected via the bushing 4.
The connecting portion is connected via a connector 5 or a bushing 4.

[Problem that the invention seeks to solve]

A curl cord 3 is used to connect the conventional telephone body and the receiver, and it is fixed on both the telephone body side and the handset side, so when a signal is received in the telephone and the handset is picked up from the telephone body, the curl cord 3 is used. If the recipient of the call is someone other than the person who picked up the handset, hand the handset or place it on the desk and then change the direction or the hand with which the recipient picks up the handset. Curl cords (twists occur) due to the twisting (right and left hands), and when these twists overlap, they become tangled, making it difficult to operate and causing the core wire to break, resulting in a shortened lifespan.

[Means for solving problems]

The present invention solves the above-mentioned problems and provides a connecting machine with a rotating mechanism that can easily eliminate twisting of curled cords.

In other words, a connecting device with a rotating mechanism installed in the middle of the connection cord of various terminals is connected to a pair of rotating terminal plates with connecting terminals planted on both sides, and conductivity is established between the pair of rotating terminal plates. a ball support plate formed by loosely fitting a plurality of balls, which are rotatably supported by a support shaft via a spring, and a cover fitted to the pair of rotary terminal plates, or one of the rotary terminal plates; This problem can be solved by using connector pins as the connection terminals.

[Effect]

By using such a connecting device with a rotation mechanism, twists occurring in the curled cord can be easily eliminated, and the operability of the receiver can be improved, and the service life of the receiver can be extended.

〔Example〕

FIG. 1 is a diagram illustrating an embodiment of the present invention.

B' is a view taken along the arrow B', (d) is a view taken along the line CC', and (e) is a side cross-sectional view with one side as a connector, in which the same parts as in FIG. 3 are given the same reference numerals.

In the figure, a connecting terminal 7.8 made of a conductive metal such as copper and having a hole 71.81 in the center is shown in FIG. 1(b).
, Td) (a pair of rotary terminals made of a synthetic resin molded product, which are implanted on both sides of a rotary terminal plate 6 with a hole 61 in the center and a protrusion 62 at the negative end) A plate 6 is formed.

On the other hand, the ball support plate 10 is made of a synthetic resin molded product as shown in FIG. A ball support plate 10 is provided, and the cross section is formed into a square shape.
A plurality of electrically conductive balls 9 (iron balls or the like whose surfaces are plated with precious metals) are fitted into the ball loose fitting holes 102 and held between the pair of terminal plates 6 in the form of a rod, A support shaft 12 made of a conductive metal such as brass is inserted into the holes 61 and 101, and is rotatably supported by a spring stopper 13 with a spring 11 interposed therebetween.

After inserting the curl cord 3 into the cord insertion hole 141 formed in the cover 14 made of a synthetic resin molded product, the core wires 31 are bonded to the connection terminals 7 and 8 with solder, and the cover 14 is connected to the rotating terminal. When fitted onto the plate 6, the core wires 31 soldered to the connection terminals 7 are electrically connected via the balls 9, and the other core wires 31 are connected to the connection terminals 8 and the support shaft 12.
．． The spring stopper 13 and the spring 11 are electrically connected to each other.

FIG. 1(e) shows a connecting machine with a rotating mechanism in which the protruding parts of the connecting terminals 7 and 8 implanted in one rotating terminal plate 6 are extended to form a connector pin 15, and one side is used as a connector. This connector can be inserted into the phone body.

By doing so, the rotating terminal plate 6 to which the curl cord 3 is soldered rotates via the ball 9 due to the twist of the curl cord 3, so that the twist can be easily eliminated.

Fig. 2 is a diagram explaining the present invention in detail, (a) is a perspective view, and (b) is an enlarged view of the main part of the connection part, and the same parts as in Fig. 1 are given the same reference numerals. are doing.

The connecting part with the curl cord 3 is connected using the connecting machine with a rotating mechanism with one side as a connector as explained in Fig. 1 +d+.
The two are connected to each other via the rotary mechanism-equipped connector described in FIG. 1(a).

In this embodiment, the connection device with a rotating mechanism is used between the telephone main body side and the curl cord, but depending on the usage condition, one connector may be provided on the telephone main body side. Further, although the explanation has been given using four balls 9, the number is not limited to four, but may be three or more.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the twists and entanglements of the curled cord can be easily eliminated, which improves operability and is extremely effective in extending the life of the cord.
