Description

 V i

The invention relates to instrumentation and can be mainly used in control and test equipment, where a simple and low-labor-intensive process of communicating the volume under study, the circuit, and the necessary software parameters with the simultaneous "yes-no" control is required.

The known switching panels of the devices are made of insulating material and contain in these holes contact pairs electrically connected; they are connected to switched circuits and included in the instrument’s package with a conductor pin and pin that carry the switching elements I.

Such panels provide a certain amount of switching combinations by filling in a certain way switching points in the switching panel.

Due to the impossibility of using in the devices switching panels with large dimensions, since the latter significantly affect the dimensions of the devices, the number of switching: the combinations become very limited, which leads to a limited range of dialing (01 panels and devices operating according to this principle.)

In addition, the time for implementation of the tcoMmutan is determined by the time of commutation of switching points in the plug of the pin of the device that does not meet the requirements of urgency of finding the NIN failure and repair of the radio devices (not effective), and creating a contact piece and the body of the unit and the body of the unit and the body of the unit. will lead to greater joint forces and especially disconnected commuting fields, which is practically impossible to implement constructively.

There are also other switching panels that are closest to the invention, which consist of not a contact plate, in the holes of which current-carrying contacts are placed, and switching elements that have, like the analogue of the preceding, the above-noted drawbacks 2.

Claims (2)

The purpose of the invention is to expand the functionality. This goal is achieved in that the switching panel is provided with a pressure frame, a printing stencil and fastening elements, the switching elements are made in the form of a printing stencil, in a printing stencil, a contact plate, and the pressure frame are coaxially drilled and the guide pins are installed, and the printing stencil, installed between the presser frame and the contact plate and connected to the last presser frame and bank elements. The conductors on the board contacts are made in the form of a conical helically-axial spring, the upper part of which has the shape of a cylindrical helix. This achieves the fact that the separation force of the printed pattern with the contact plate is absent, and the coupling force is sufficiently small with a large number of contacts. Reliability of contact is ensured by contact of the flat part of the contact of the stencil with the edge of the spring in the form of a cylindrical spiral than the contact. line of contact. Parallelism of the contacting surfaces is provided by the samovar | ovation in contact. Extensive functional areas are provided by the fact that for the specific devices under investigation, for example, using the method of foiled materials, it is possible to pre-fabricate stencils in advance, and they can be replenished during the operation of the devices. The contact-clamping frame ensures reliable clamping, fixation and quick stencil change, which ensures high productivity in operation. FIG. I - shows a general view of the panel in FIG. 2 shows the component parts of the panel; FIG. 3 - 4 shows sections A-A and BB, panels in the interactions of the nodes. The flat-contact switching panel consists of a contact plate 1, with holes to accommodate the current lead c (their spiral-axial springs 2, guide pins 3, printing stencil 4 with built-in contacts 5, contact-clamping frame 6, plate 7, and CKpertlie elements 8. The pins 3 are installed in coaxially made holes 9, 0, II, respectively, made in the presser frame, the printing stencil and the contact board.On the contact plate 1 is superimposed along the guides pin 3 of the contact-presser frame O together with the previously installed The printed stencil 4 is fixed with the fixing plates 7, then the frame is pressed against the contact field and fixed with fastening elements 8. The contacts 5 of the printed stencil contact the contact surface of the spiral-axial springs 2, as a result of which an electrical connection of the switched circuits occurs. the contact-contact frame is provided with holes for monitoring the object under investigation in the diagnostic mode using a tester. The use of this panel design allows you to reduce the time for a single inspection. Claims.
