Description

The invention relates to electronic equipment, in particular to contact devices used to connect the contact elements of electronic products to installations for measuring parameters.

A contact device is known that is used in instrumentation for connecting the terminals of integrated circuits with blocks for setting modes and parameter control (patent RU No. 2042993, IPC H01R 23/68). However, it is used only for monitoring electronic products with bent leads on two sides and does not allow checking electronic products with flat contact pads, and the contact device has a complex structure.

A contact device is known that is used in control devices for connecting integrated circuits in flat cases with flat terminals to measuring circuits (copyright certificate SU No. 501503, IPC H05K 1/04, H01R 9/22). This device is used only for monitoring products with flat terminals on two sides. It has a complex structure.

The closest taken as a prototype is a contact device (copyright certificate SU No. 1173567, IPC H05K 1/18) for connecting electronic products containing a dielectric base with elastic contacts fixed in it, a separation dielectric element and a pressure cover. The dividing element is made in the form of a set of identical flat plates vertically located between the elastic contacts with a recess under the body of the electronic product, freely located on the base. This device can be used in equipment for controlling the parameters of electronic products in a housing with planar leads. Partial unification of contact devices for housings with planar leads on two sides, with a different number of leads is provided.

The known contact device does not allow to achieve unification for its use in measuring the parameters of electronic products with planar leads located on four sides.

The technical problem to be solved by the development of this invention is the creation of contact devices for measuring the parameters of electronic products in various buildings with different numbers and locations of contact elements, while ensuring reliable contact.

The technical result that is required to be achieved in the development of this invention is to ensure the unification of the design of the contact device through the use of components, changing which you can use the contact device to measure the parameters of various electronic products with different numbers and locations of contact elements while making reliable contact.

The technical result is achieved due to the fact that the contact device contains a base of dielectric material on which elastic contacts are attached, a separating element of dielectric material with a recess for mounting the body of the controlled electronic product and a pressure cover, the separation element being made of one above the other, rigidly fixed on the basis of plates of dielectric material, which contain grooves and cutouts of various sizes and locations for placement elastic contacts in them, isolating them between themselves and positioning the working part of the elastic contacts to the corresponding contact elements of the monitored electronic equipment product, while the lower plate of the separation element is fixed to the base, and the recess under the body of the monitored electronic product is located in the upper plate of the separation element, from the side of the pressure cap, technological sleeves can be installed between the plates of the separation element.

In FIG. 1 shows a design of a contact device, a longitudinal section; in FIG. 2 - the design of the contact device for electronic products in the housing QLCC40 / 40-1.

The contact device contains a base of dielectric material - 1, on which the lower dielectric plate - 2 is located, there are elastic contacts - 3, technological sleeves, which are installed, if necessary, around the perimeter under the intermediate dielectric plate - 5, which isolates the elastic contacts between themselves and positions the working part of the elastic contacts - 3 to the corresponding contact elements - 6 of the controlled product of electronic equipment - 7, the upper dielectric plate - 8, in which a recess for the body of the controlled electronic product, pin - 9, fixing plates - 2, 5, 8 one above the other and relative to the base - 1, pressure cover - 10. In FIG. 1 clamping cover - 10 and a controlled product of electronic equipment - 7 with contact elements - 6 are shown conditionally.

Contacting is as follows.

When the pressure cover is open - 10 the controlled electronic product - 7 is laid with the contact elements - 6 down, in the recess in the upper plate - 8. When the pressure cover is closed - 10, the body of the electronic equipment - 7 is pressed to the intermediate dielectric plate - 5, the contact elements - 6 of the checked product of electronic equipment - 7 are pressed against the working part of the corresponding elastic contacts - 3. The pressure cover - 10 is locked with a latch (not shown). Contacting completed.

The separation element of the proposed contact device consists of plates of dielectric material mounted one above the other, which can be easily replaced. The size and location of the grooves and cuts in these plates and their thickness, as well as, if necessary, application, and the height of the process sleeves, are selected and made depending on the height, shape and number of elastic contacts that are necessary for contacting when measuring the parameters of a particular controlled product electronically technicians.

The necessary elastic contacts are installed on the dielectric base in the grooves and cutouts of the lower plate of the dielectric material of the separation element. The positioning of the working part of the elastic contacts to the contact elements of a particular controlled product of electronic equipment is carried out using grooves and cutouts made in the intermediate plates of the dielectric material of the separation element, their number depends on the height of the elastic contacts and can be adjusted using technological bushings. In the upper plate of dielectric material, a recess is made for a specific controlled product of electronic equipment.

Thus, replacing the constituent parts of the contact device, namely, plates made of the dielectric material of the separation element adapted for positioning the working part of the elastic contacts to the contact elements of a particular controlled electronic equipment product, the proposed design can be used to measure the parameters of various electronic products in various housings with different locations and the number of contact elements and the implementation while reliable contact. Unification of contact device achieved.

The contact device has been tested for electronic products in the QLCC40 / 40-1 package. The QLCC40 / 40-1 housing has 40 contact elements located on four sides. The contact device is made in accordance with the invention and consists of a dielectric base - 1, a lower dielectric plate - 2, elastic contacts - 3 in an amount of 40 pieces, a process sleeve in an amount of 4 pieces, an intermediate dielectric plate - 5, an upper dielectric plate - 8, the pin - 9 in the amount of 4 pieces, the pressure cover - 10 (not shown conditionally). The grooves and cutouts in the dielectric plates - 2 and 5 were selected with the aim of accurately locating them and bringing the working part of the elastic contacts - 3 to the contact elements - 6 of the controlled electronic product - 7 in the QLCC40 / 40-1 package. The height of the location of the intermediate dielectric plate - 5 to provide the necessary protrusion of the working part of the elastic contacts - 3 can be set by using technological bushings - 4 of a certain height. The recess in the upper dielectric plate - 8 ensures an exact fit of the QLCC40 / 40-1 housing and fixes the electronic product at a certain height. The use of technological bushings of a certain height between the plates of the separation element allows you to set the intermediate dielectric plate - 5 to the required height and provide the necessary and sufficient force to press the elastic contacts - 3 on the contact element of the controlled electronic product - 7 when lowering the pressure cover - 10 (not shown conventionally) , which allows to increase the life of the contact device, in particular elastic contacts - 3, and also provides reliable contact them with and building electronic equipment - 7 without destroying the appearance. Reliability of contacting is also ensured by increasing the reliability of positioning of elastic contacts - 3 to contact elements - 6 electronic products - 7 in the slots and cutouts of dielectric plates - 2, 5 of the separation element, eliminating the closure of adjacent elastic contacts - 3 with each other and eliminating the possibility of them deviations from the vertical arrangement.

Thus, the proposed design made it possible to create a contact device for the QLCC40 / 40-1 housing with flat contact elements on four sides and at the same time ensure reliable contact.

Also, the contact device has been tested for electronic products in a non-standard case, in the form of a printed circuit board, with an arbitrary arrangement of contact elements in the amount of 10 pieces. The design of the contact device is made in accordance with the proposed invention and consists of a base of dielectric material - 1, a lower plate of dielectric material - 2, elastic contacts - 3 in the amount of 10 pieces, a process sleeve in the amount of 4 pieces, an intermediate plate of dielectric material - 5 , the top plate of dielectric material - 8, in which a recess was made for an electronic product in a non-standard case, a pin - 9 in the amount of 4 pieces, a pressure cover - 10. To ensure cities account for major area of contact and a reliable clamping to the contact pads of the tested article of electronic equipment were selected elastic contacts - 3 with the increased area of contact of the working part. The use of technological bushings of a certain height between the plates 2 and 5 of the separation element helps to set the intermediate dielectric plate - 5 to the required height, to ensure the protrusion of the working part of the elastic contacts - 3, and to provide the necessary and sufficient force of pressing the elastic contacts - 3 on the contact element of the electronic technology - 7, which allows to increase the life of the contact device, in particular elastic contacts - 3, and also provides reliable contact e with the product of electronic equipment - 7 without fracture appearance.

Thus, we can conclude that the present invention allows to solve the technical problem. The proposed design of the contact device can be used to measure the parameters of electronic products in various housings, with a different number and arrangement of contact elements, while ensuring reliable contact.

The technical result, which consists in ensuring the unification of the design of the contact device through the use of components, changing which you can use the contact device to measure the parameters of various electronic products with different numbers and locations of contact elements while making reliable contact.

The unification of the proposed contact device is achieved by changing the size and location of the grooves and cutouts in the dielectric plates of the separation element and their thickness, by choosing the necessary shape and number of elastic contacts, as well as by changing the shape and size of the recess for the controlled electronic product. To ensure the necessary height of the protrusion of the working part of the elastic contacts can be used technological bushings of a certain height. In addition, the proposed design of the contact device is more technologically advanced than the known ones, since the plates in it are made of sheet dielectric material and do not require molds and other complex equipment for their manufacture, which can significantly accelerate the process and reduce the cost of its manufacture. All this allows to significantly increase the economic efficiency of contact devices developed in accordance with the invention.
