Electromagnet pusher-interacts with a movable contact element, pressed the output of the product between the movable and stationary contact elements. 2 Il.

Description

The invention relates to electrical engineering, in particular to contact-clamping devices used to connect the leads of products to electrical measuring instruments.

A known contact block containing an insulating base with contact elements secured therein.

This contact device is characterized by sufficient simplicity and small dimensions, but it does not provide high reliability of contact and high performance in operation, especially when connecting thin and flexible terminals of radio elements to the measuring device.

Closest to the present invention is a contact device for connecting electrical terminals, comprising an insulating base with a metallized hole (fixed contact element) and a flat movable element (movable contact element) mounted in the hole with the possibility of movement relative to its surface.

This device is designed to connect electrical leads and allows for increased functionality as a result of increased electrical lead density.

However, the known device due to its design features does not provide automatic clamping of the terminals between the contact elements (fixed annular

 surface and a movable element inside the hole) with their simultaneous connection to the measuring device, which, in turn, has a negative effect on improving the reliability of contact and performance and does not allow expanding the technological capabilities of the device. The purpose of the invention is to increase the reliability due to automatic operation with the introduced output of the product.

FIG. 1 shows a block diagram of a contact clamping device; in fig. 2 is an electrical circuit diagram of the device.

The clamping device comprises a sensor A (K1) connected between the contact elements 2 and 3, and an electromagnet 5 (X1) connected to an electric sensor 4 and provided with a pusher 6 for moving the movable contact element 3 for clamping the output 7 of the connected product between the contact elements 2 and 3. A fixed contact element 2 and a movable contact element 3 are fastened to the insulation base 1, between which an electric sensor A is connected. The pressure mechanism of the movable contact element 3 is designed as an elec a magnet 5 connected to the sensor A and fitted with a pusher 6. In this case, the electromagnet 5 is installed with the ability of the pusher 6 to interact with the movable contact element 3, which is set at an angle to the stationary contact element 2, and the minimum distance between the contact elements 2 and 3 is smaller than the diameter pin 7 of the connected product.

The electric sensor A is made in the form of an electromagnetic relay connected to a power source (not shown) and triggered when the terminal 7 closes contact elements 2 and 3. When the sensor A triggers, the electromagnet 5 turns on

The electromagnet 5 has a movable bark 9, on which is fixed a pusher 6, which displaces a movable contact element 3 spring-loaded 8 with a fixed contact element 2 to a fixed contact element 2.

Contact-clamping device operates as follows.

The output 7 of the product is introduced into the gap between the contact elements 2 and 3. Since the movable contact element 3 is at an angle to the movable contact element 2, the output 7 at some point will close the contact elements 2 and 3; When the contact elements - and 3 are closed, the electric sensor A, which you

will give an electric signal to the electromagnet 5. When the electromagnet 5 is triggered, its measles H will move the movable contact element 3 through the pusher and fix the pin 7 between the contact elements 2 and 3. The fixed pin 7 is automatically connected to the measuring device. (not shown). After the necessary control operations have been completed, the power supply of sensor A is disconnected. The circuits of sensor A and electromagnet 5 are de-energized. In this case, the bark 9 of the electromagnet 5 occupies the initial position and retracts the pusher 6 from the movable contact element 3, which by means of the spring 8 moves away from the fixed contact element 2, and the output 7 of the product is released and removed from the gap between the contact elements 2 and 3. Thereafter the gap between the contact elements 2 and 3 introduces pin 7 of the next product and repeats the process.

The use of a contact-clamping device can reduce the labor intensity by 2-3 times, increase productivity by 20-30% and by 2-3 times the service life of the contact elements.
