Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a connector used for seamless connection of non-telephone digital lines.

It goes up and down.

When switching non-telephone lines, if you simply make multiple connections and switch as with conventional telephone lines, there is a risk that the impedance of the line will change suddenly and error bits will occur in the digital signal.

Therefore, to prevent this from happening, the following new switching method has been developed.

4 or more and 1J (Fig. 12) (1) Low resistance 12 and high resistance 22 to the current core wire 10
The switching core wires 20 inserted in series are multi-connected.

(2) Cut the current core wire 10 at the switching point 14.

(3) At the same time as decreasing the value of the high resistance 22, increasing the value of the low resistance 12.

If this is done, the flow of the transmission signal will not cause a sign error from the working core wire 10 to the switching core wire 20.

It can be switched without any problem.

(4) Thereafter, the current core wire 10 and the switching core wire 20 are connected, and each of the resistors 12 and 22 is removed to complete the switching.

By the way, in order to implement the above method, it is necessary to connect and disconnect many tubes for one core wire.
゛When the number of core wires increases, the work becomes more difficult.

An object of the present invention is to provide a connector that can efficiently carry out the above switching method.

As shown in FIGS. 1 to 3, this connector for use as a connector consists of (1) a pair of connector halves 30A and 30B;

(2) In each half, an L-shaped conductor 34 is buried in the main body 32, and the upper end of the vertically rising part of the L-shaped conductor is 1
(3) The tip of the horizontal portion of the L-shaped conductor 34 also protrudes from the side surface of the main body 32 to form a contact 4OA having a groove 38 for connecting the conductor. B, and the contact is capable of being removably engaged with the contact of the other half.

Support 0 Details Top 1 Shell (Figures 1 to 3) The connector halves 3OA and 30B are almost the same. Therefore, one half of the connector 30A will be described, and only the different part 30B will be described.

The main body 32 is a substantially cubic insulator in which the iL-shaped body 4 is embedded.

The tip of the vertically rising portion of the L-shaped conductor 34 forms a core wire contact 36 . That is, there is provided a groove 38 having a width slightly narrower than the conductor of the core wire to be connected, and when the core wire is pushed into the groove, the coating is torn and the conductor is connected.

Further, the tip of the horizontal portion of the L-shaped conductor 34 also protrudes from the side surface of the main body 32 to form a contact 4OA, and can be detachably engaged with the contact 40B of the mating connector half 30B.

That is, when both are divided into three contact pieces 44, 46, 48 by, for example, two slits 42, and are engaged with each other (FIG. 3), the center contact piece 46 becomes a contact piece) 4.
The 0A one is on top of 40B, and the left and right contact pieces 44 and 48
The contact 4OA is placed below 40B, and due to the action of its own spring, it tightly presses together and maintains electrical contact.

If you pull it left and right again, it will separate.

Note that the structures of the contacts 4OA and 4H are not limited to those described above.

1. Normally, both of the co-octactor halves 30A and 30B are of a multiple type in which a large number of them are arranged in a direction perpendicular to the plane of the paper in FIG.

Reference numeral 50, also shown in FIG. 3, is an adapter used auxiliary at the time of switching connection.

This protrudes a contact piece 54 below the insulator 52, which
A lead wire 60 is attached to the upper part 56 of the contact piece 54, which is adapted to engage with the core wire contact 36 (see FIG. 2).
Connect. 58 is a cap.

A method for performing the above-mentioned new switching using the above-mentioned connector will be explained for only one side of the switching (corresponding to the left half of Fig. 9).

The same thing is done on the opposite side at the same time and in synchronization.

(1) As shown in FIG. 3, introduce the connector halves 30A and 30B, and as shown in FIG. 4, attach them to the current core wire 1O with the switching point 14 in the center. Note that 49 in FIG. 3 is a cap.

(2) As shown in FIG. 5, attach another connector half 3OB' to the switching core wire 20.

Then, using the adapter 50, the low resistance 12 is placed between each core wire contact 36 of the connector halves 30A and 30B, and the high resistance 22 is placed between the connector halves 30A and 30B.

Each is connected between each core wire contact 36 at 30A and 30B°.

(3) Cut the current core wire 10 at the switching point 14, and separate the connector halves 30A and 30B as shown in FIG.

Then, as described above, the resistance value of the high resistance 22 is lowered, and at the same time the resistance value of the low resistance 12 is increased.

(4) As shown in the ffS7 diagram, connector halves 30A and 30
B° and disconnecting each adapter 50 completes the switching (FIG. 8).

Note that an arbitrary switching clip may be used instead of the dedicated adapter 50 as described above.

5Ω usage month n (Figures 9 to 11) In the above method, instead of the connector half 3OB that is attached to the current core wire 10 to be removed after switching, a known switching connection holder 60 (or any other suitable alligator clip) is used. good)
This method uses

The rest is exactly the same as above, but to briefly explain: (1) Attach the connector half 30A and the connection holder 60 to the current core wire 10 (Fig. 9), (2) Cut at the switching point 14. 10), (3) Connect the connector half 30B attached to the switching core wire 20 to the connector half 30A (FIG. 11), (4) Remove each adapter 50 to complete the process (see Figure 11). Figure 8).

By doing so, in the above method, it is possible to eliminate waste of the connector half portion 30B that is stored in the tank after the switching is completed, and it is also possible to reduce the number of connectors used.

Note that the connection holder 60 can be used repeatedly as a tool.

3 and 1 A new switching method for non-telephone lines can be implemented efficiently.
