Description

The invention relates to electrical engineering and can be used to switch the communication line of systems, as well as to take electrical characteristics from the communication line.

A bridging device is known, which consists of the conductor of its tire with spring-loaded petals bent from it, with openings in the place of their bends. The tire is mounted on the bridged contacts of the type of pins arranged in a row so that the bridged contacts are put on the tire opening, and the tire and its lobes are in contact with them.

If it is necessary to skip the contacts that are not to be bridged, the tire is removed and opposite to these contacts, insulating material is placed on the tire, and the petals are wrapped in this place.

The specified device does not allow switching of the cable line in the system, as well as bridging of randomly located contacts in different rows.

A device for bridging contacts in a connector, comprising a connector with a housing, bridging removable contact elements made of an elastic sheet material, which cooperates with a contact board, is known, the contact elements being zigzagged and mounted on the shanks of the bridged connector contacts, can bridging the connector contacts in an arbitrary order When setting up a different jumper circuit, the device is removed from the switching unit, the contact elements are removed, the contact elements are removed from the contact crosses, transferred to the shanks of other contacts, and the device is assembled again.

This device does not allow the commutation of the communication bus in the system (device-cable-device), the changeover of the device to a different circuit takes a long time. In addition, readjustment requires disassembly of the device and does not allow the removal of electrical characteristics from the line under investigation.

Closest to the present invention is a device for bridging the connector contacts, comprising a housing, a contact board with a current-carrying layer, mounted on the housing perpendicular to the axis of the jumper contacts, fixedly mounted on the current-carrying layer of the board contacts, liro-shaped contact elements with holes made in their base, and petals facing the upper wall of the case, it is equipped with a removable adapter contact plate with contacts made on one side in the form of pins, and on the other side in e nests set removable hollow insulating element, the current-carrying bus terminals are electrically bonded to the current carrying contact board layer, wherein the top wall of the housing formed guide holes for inserting therein bare removable insulating elements, and

0 in the contact plate and its current-carrying bus there are step openings for insertion of a removable transitional contact board into them.

This device does not allow production of the commutation of the communication line in the system (device-cable-device), and also requires the installation of additional hollow insulation elements during the readjustment. The aim of the invention is to improve manufacturability.

This goal is achieved by the fact that the device for crossing the contacts of electric circuits, containing boards with contacts located coaxially with each other.

5 is equipped with bridges in the form of pins for closing the contacts and flexible current-carrying bridges, while the contacts are made in the form of tubular sockets.

The device is convenient in operation, it allows to bridging (switching) the electrical circuits of the system without dismantling the cable line, bridging (switching) the electrical circuits of the system of any contacts and does not require special readjustment.

FIG. 1 and 2 shows the location of the sockets and their markings; in fig. 3 - the device, section; in fig. 4 is a diagram of an electrical device; in fig. 5 is a diagram of connecting the device to the system (device-cable-device).

The device for crossing the contacts of electrical circuits consists of connectors 5, 1, boards 2, sockets 3, pins 4, jumpers 5, wires 6, pins 7, cable 8 and device 9 systems.

The device is equipped with a flexible metal jumper 5, made of MGSHA type wire, at the ends of which two pins are installed and which are galvanically connected by means of jumper 5, two boards 2, which are made to a dielectric, on the planes of which there are sockets, 3 in number, equal to the number of contacts in connector 1. Contact sockets 4 are marked on 1a, 2a ... etc. In accordance with FIG. 4 at the ends of the boards 2 are installed on one connector 1. In this case, the connector MP is installed

with the number of contacts equal to 102. To allow the sockets 3 and pins 4 and 7 to contact, the board 2 is designed in such a way that both parts of the socket 4 of the same contact of connector 1 are located on the same axis. To provide a set of schemes without change, pin 7 is used, and to change the scheme, a flexible metal jumper 5 and pins 4 are used, while its length must be equal to at least half of the perimeter of the board 2.

Contact Jumper

electrical circuits works as follows.

Connect the device to the system (Fig. 5), i.e. During the opening of the cable 8 of the system, consisting of the device 9 and the cable 8, the following work is performed to jump the contacts of the system. In those sockets 4 that do not require a change in the circuit of the communication line, the pins 7 are installed, which provide a set of the scheme without change, i.e. One-to-one, in slots 4, which require a set of new schemes, are left free.

Example. For example, 51-D1 must be changed to chain 51-DYOO. In this case, pin 4 with a flexible metal bridge 5 is installed in socket 4, marked out as 15, and in socket 4, marked 100A, the chain 51A100 is produced with the help of pins 6 and jumper 5. The modified electrical circuit of the system has been obtained.

As shown by the analysis of the design of the device and its experimental testing

in comparison with the prototype, exclude the manufacture of parts of complex construction, as well as bridging the contacts without using a printed circuit board, okome, if you install jumper 5 in the disconnection

measuring device, it is possible to make the electrical characteristics of the communication line of the system.

This device makes it possible to increase the workability of the part and assemblies approximately three times, to reduce the dimensions by approximately five times, to improve the quality of the measurements approximately six times.

In addition, the simplicity of technological and design allows

reduce labor costs by about three times, and due to its small size it is convenient to operate.
