Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a connector jack used in an information transmission line in which a plurality of devices are connected in series, and in particular,
This invention relates to a connector jack with a switch function that has contacts that short-circuit each pair.

An information transmission system that performs a conventional technology relay connection has relay devices A2 to 5n- between both end station devices A1 and An, as shown in FIG.
i are arranged in series, and each relay device is connected by fitting the connector plug 8 of the connector jack 71C device of the transmission line 6.

Conventionally, the connector jack used for this type of relay connection is as shown in the upper part of Fig. 4 and the upper part of Fig. 5 when viewed from direction A (however, the second contact 3 is removed from this drawing). A plurality of pairs of input/output jack contacts 1 are arranged in parallel. The cross section of one pair of them has a structure as shown in Fig. 7, and one connector glug 8t of the relay device shown in the middle part of Fig. 4 and the lower part of Fig. 5 when viewed from direction B. - Input/output connections were made by inserting. Therefore, if a failure occurs in one of the relay devices and you want to remove this device, pull out the connector plug 8 of the device and short-circuit the input and output with the short-circuit wire 11 instead as shown in Figure 8. To achieve this, a method of inserting another shorting plug 10 has generally been used.

However, in order to do this, short-circuiting plugs must be prepared at all times, resulting in increased costs and man-hours, and there are disadvantages in that information during replacement work is not transmitted.

Problems to be Solved by the Invention The purpose of the present invention is to solve the above-mentioned drawbacks, namely, when removing a faulty relay device, a shorting plug must be inserted into the connector jack of the transmission line, and during this work. To provide a connector jack with a switch function that solves the problem that information is no longer transmitted.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention consists of a jack case and two pairs of jack contact pieces inside the jack case, and each pair of jack contact pieces has the following features: Connected to the plug contact piece when mated with the connector plug! ! The present invention employs a configuration having one contact and a second contact that is short-circuited when the connector plug is not fitted and disconnected when the connector plug is fitted.

Operation Since the present invention is configured as described above, when the connector plug is fitted, the first contact of the jack contact piece is electrically connected to the plug contact piece, and the second contact of the paired jack contact piece is disconnected. Conversely, when the connector plug is removed, the second contacts of the pair of jack contacts are short-circuited.

Example Next, embodiments of the present invention will be described with reference to the drawings.

Referring to Figure 4, which is a perspective view of an embodiment of the present invention, and Figure 5, which is a front view of the mating surfaces of the connector jack and the connector plug, respectively, as seen from direction B, it will be understood that The connector jack 7 with a switch has 3 pairs, that is, 6 jack contact pieces 1t- that face each other, and the near connector plug 8 also has 3 pairs of plug contact pieces 5, which fit together to connect input and output. I do.

Next, please refer to FIG. 1, which shows this embodiment in cross section.

This embodiment includes a jack case 4 and a pair of jack contact pieces 1.1 that are engaged within the jack case 4 via a spring 9.
Each jack contact piece 1 has a first contact point 2 that connects with a plug contact piece, and a second contact point 3 that makes contact with the pair. Fig. g1 shows the state before the connector plug is fitted, Fig. 2 shows the plug in the intermediately inserted state, and Fig. 3 shows the completely fitted state.

Next, the operation of this embodiment will be explained using FIGS. 1 to 3. First, in FIG. 1, two jack contact pieces 1, 1
The jack is pulled forward from the jack case 4 by the force of the spring 9, and the second contacts 3, 3 of the pair of jack contacts 1.1 are short-circuited to each other. Next, in FIG. 2, plug contact piece 5
is inserted and the iE1 contact 2vc of the jack contact piece 1 is electrically connected, but the second contact 3 is short-circuited and remains at 9. When the spring 9 is further inserted and completely fitted as shown in FIG.
, 3 are separated. Conversely, when the connector plug is removed, the order of FIG. 3→FIG. 2→FIG. 1 occurs, and the second contact 3.3 of the jack contact piece is short-circuited.

Therefore, by using the connector jack with a switch function of the present invention as the connector jack 7 of the information transmission system shown in FIG. This eliminates the need for time-consuming operations and loss of information, and eliminates the need for short-circuit connector plugs.

Although this embodiment has been described assuming that there are three pairs of jack contacts, the present invention can be applied to any case where there are one or more pairs of jack contacts.

Effects of the Invention As explained above, according to the present invention, by adding a second contact to the jack contact piece, there is no need to perform a special 6-position even if any device in the transmission line is disconnected. This has the effect of guaranteeing a serial transmission line.
