Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an unexploded I14#i multi-pole shielded connector.

Transmission equipment, measuring equipment, etc. are connected using shielded wires to completely prevent external noise from entering the signal circuit being transmitted.

Since the shield 1jsFi has a four-layer structure consisting of a center conductor, an insulator, a shield conductor, and an insulator, it is not easy to connect between the devices. In order to reduce the number of cables 13 used to connect the m devices 11 and 12, a serial transfer method is used, however, in such a serial transfer method.

The disadvantage is that the data transfer speed is inevitably slow.

On the other hand, in order to connect multiple signal sources and measurement equipment, it is necessary to wire dedicated cables between each signal source and the measurement equipment, and as in the data transfer described above, one connection cable
It cannot be reduced. In such a case, as shown in FIG.
Connection cables 2s to 26t are connected using a large number of coaxial connectors, or a coaxial flat cable connector 32Q to which a coaxial flat cable 31 is connected as shown in FIG.

However, the former method has the problem that many coaxial connectors must be individually disconnected when devices are repeatedly connected and disconnected, and it is not easy to connect and disconnect them.Also, the latter method requires only one connector. Therefore, it is easy to connect and disconnect 1, but as shown in Figure 4, the connector 33'
, printed 1Ijs board 41 mounted with the inside of S4
Since the conductors wired between the conductor and the mounting portion 42 do not have a shield structure between them, there is a problem that they cannot be used in measurement equipment where leakage between adjacent signal lines would be affected.

The present invention solves the above problem, and the connector is
The tortoise is composed of a pair of bodies made of conductors, and has a characteristic that a plurality of pairs of connector bins are placed facing each other and insulated and embedded in each of the bodies.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 5 is a structural sectional view showing an embodiment of the present invention. That is, the connector is connected to a pair of main bodies 51 . made of conductors.
55, one body 51 [i a plurality of hollow holes 52
are arranged in parallel, and an insulator 53 such as Teflon is placed coaxially on the connector bin 54 [7] and inserted into each hole 52 of the main body 51. The other main body 55 has hollow holes 56 corresponding to the holes 52 of the main body 51, and there are four contact surfaces 58vil and 58vil with the connector bin 54, and an insulator 57f such as Teflon is placed coaxially on the connector bin 59. This is then embedded in the hole 56 of the main body 55, facing the connector pin 54. Also, the previous We vs.? Eggplant body 51.
The connector bins 54 and 55 face each other in a state 11 in which the connector bins 54.5 are butted against each other, and both are connected by a fixing screw 60. The present invention provides that the center conductor 6 of the shielded wire 61 is attached to each of the connector bins 54, 59 as shown in FIG.
2 connected 17, and a shield conductor 6 connected to each of the main bodies 51 and 55.
Connect and use 3. Incidentally, an example of the use of the present invention is shown in FIG. 6, but this is an example and is not limited thereto.

Also 1 unexploded IPl#'i said connector pin 54.59
Since a multi-pole structure can be easily obtained depending on the number of embeddings and the arrangement pitch, a 1j42-pole shielded connector could be realized in the embodiment of the present invention.

FIG. 7 is a structural sectional view "1." showing another embodiment of the present invention. That is, a shield conductor 63f of a shielded electric wire 61 is fixed to the rear edge of each main body 51.55. A fixing part 72 is provided for fixing the conductor 63 with a fixing plate 71 made of a conductor.
is held down and fixed to the fixing part 72, and the fixing plate 7
1, the connection part between the conductor 65 and the connector pins 54 and 59 has a completely shielded structure.

Further, the front edge 55ai of the main body 55 is extended Km in front of the main body 55 to cover the connection portion between the two connector pins 54 and 59 to form a shield structure. In this embodiment, the signal line is completely covered with a shielded conductor, resulting in a highly noise-resistant connector. However, it is clear that if the connector bin is placed horizontally with a conductor, the same effect as described above can be obtained with other embedded structures, such as a structure in which it is sandwiched in a metal body. As shown in the figure, one of the main bodies b5.'4r device @ this pipe device panel 81
Attach the locking screw 82 to t! Ht'1. .

'This is used as a pole to connect the other main body 51.
It is clear that by providing a cable cover 84 with a cable and exit port 83, the multi-pole shielded connector of the present invention is easier to use.

As described above, according to the present invention, the connector is composed of a pair of main bodies made of conductors, and a plurality of pairs of connector bins are placed facing each other and are insulated and inserted into the front main body. I can do it.

It has high noise resistance and can be used in measurement equipment that is affected by leakage between adjacent signals. Furthermore, since the main body can be easily attached and detached using a set screw, it has the effect of making it easy to connect devices.
