Description

The utility model relates to instrumentation and can be used for mounting and cooling active devices, sensors and other devices, for example, generator lamps of a high-voltage module.

A device for cooling active devices is known (Author's certificate No. 520625, IPC: G12B 15/04, 1976), for example, of generator lamps, containing a pipe connected by impulse tubes to the cameras of the actuator. In this case, one of the impulse tubes is fixed in the pipeline at the installation site of the device to be cooled, and the other in front of the device to be cooled.

The disadvantage of this device is its structural complexity.

A device for mounting the device on a panel is known (Author's certificate No. 577710, IPC: H05K 7/00, G12B 9/10, 1977) containing a bracket in the form of a clamp wrapping around the device and a tightening screw. The clamp is equipped with elastic legs, forming an acute angle with the surface of the device, providing the possibility of mechanical interaction of each of them with the body of the device during rotation of the clamping screw. At the ends of the clamp there are ears bent at right angles with holes, one of which has a thread for the clamping screw.

The disadvantages of this device are:

a) the unreliability of the mounting of the device due to the insignificant area of interaction of the elastic legs with the body of the device;

b) the need for a flange on the housing of the fixed device and panel;

c) the inability to align the device.

A device for securing a device is known (Author's certificate No. 1226685, IPC: H05K 7/00, G12B 9/10, 1986), comprising a housing with coaxial cylindrical and threaded holes and with a cylindrical shoulder on one of its ends. An annular spring washer with radial slots forming petals is installed in the cylindrical hole of the housing, the free ends of which are located at an angle to the end of the washer, while the diameter of the geometric circle described by them is larger than the diameter of the housing of the fixed device.

The disadvantage of this device is the need for a flange formed by a cylindrical groove of special geometry on the housing of the device to be fixed.

A device for fixing the device is known (Author's certificate No. 1795523, IPC: G12B 9/10, H05K 7/00, 1993), comprising a housing with a central hole, an elastic element in the form of a split ring, with petals on one of its ends and with fixing screw. The device is equipped with additional fixing screws, while at the other end of the ring are made additional petals paired with it.

The disadvantage of this device is the inability to mount devices with a flangeless housing.

The closest in technical essence and the achieved results to the proposed technical solution is a device for mounting the device (Patent RU No. 49412, IPC: H05K 7/00, G12B 9/10, 2005), containing a bracket with elastic tabs covering the device, and at least one coupling element. In addition, the device contains at least one locking element, placed and fixed on the outer side surface of the bracket. At the same time, the coupling element located in the fixing element is made with the possibility of interaction with its end with the elastic tab of the bracket.

The disadvantages of this device are:

a) the unreliability of the mechanical fastening of the device due to the insignificant area of interaction of the elastic tab with the body of the device;

b) the absence of conductive heat removal from the surface of the device;

c) the unreliability of the electrical contact of the device and the housing.

The technical result, the achievement of which is claimed

the technical solution consists in increasing the reliability of the mechanical fastening of the device, providing conductive heat removal from its surface, as well as in increasing the reliability of the electrical contact of the device in the place of its fastening.

The technical result is achieved by the fact that the device for fastening and cooling the active device comprises a bracket configured to place and fasten the active device in it, a conductive contact clamp, conductive wires and at least one clamping element. Moreover, the bracket with conductive wires is mounted on a panel of dielectric material and is made of a material with high electrical conductivity and thermal conductivity, with fins on the outer side surface. The bracket contains an elastic terminal clamp in the form of a clamp with tabs in which the coupling element is placed. In this case, the conductive contact clamp with conductive wires is configured to cover the flange of the contact device and consists of two flange clamps, fixed to each other by means of fasteners.

The device for fastening and cooling the active device (Fig. 1-4) contains a bracket 1 mounted on a panel 2 of dielectric material with radio-electronic elements installed on it (not shown conditionally), a conductive contact - clamp 3, fixed on the device 4, placed and fixed in the bracket 1, as well as two or more conductive wires 5, at least one of which is in contact with the bracket 1, and the rest with the conductive contact - clamp 3.

The bracket 1 (Fig. 1-5) is made of a material with high electrical conductivity and thermal conductivity and has the shape of, for example, a parallelepiped. The outer side surface of the bracket 1 is made with fins 6 (Fig. 1, 3, 4, 5) to ensure the best heat exchange with the external environment. The bracket 1 contains an elastic terminal clip in the form of a clamp 7 with tabs 8 (Fig. 5) for placement of the device 4 in it with subsequent fixation. The terminal clamp is formed by two narrow grooves 9, 10 (Fig. 1, 5) and a blind hole 11 (Fig. 5), for example, of a cylindrical shape.

The tabs 8 are made coaxial cylindrical holes 12 (Fig. 5) to accommodate at least one clamping element 13 (Fig. 1), for example, in the form of a screw, for fixing the device 4 with a clamp 7.

On the outer side surface of the bracket 1, protrusions 14 with threaded holes 15 (Fig. 4) are made for rigidly fastening the bracket 1 to the panel 2 by means of fasteners 16 (Fig. 2, 3), for example, screws. At least one mounting hole 17 (Fig. 5) is made in the side surface of the bracket 1 for fixing one or more conductive wires 5 therein, for example, by soldering.

The device 4 (Fig. 1, 2, 4, 6), for example, a generator lamp of a high-voltage module, is made elongated, for example, of a cylindrical step shape, with a peripheral contact 18 (anode) and a flange - contact 19 (grid) in the middle part, made , for example, in the form of a thin-walled disk.

The peripheral contact 18 (Fig. 6) of the device 4, as the most heat-generating, is placed in the terminal clip of the bracket 1 and fixed in it with a clamp 7 by means of at least one coupling element 13 located in the holes 12 of the legs 8, which ensures reliable mechanical fastening of the device 4, as well as the best electrical contact and conductive heat removal from its surface. In this case, the peripheral contact 18 has the same geometry as the clamp 7 of the terminal clip.

On the middle part of the device 4 there is a conductive contact - clamp 3 (Fig. 1, 2, 4), covering the flange - contact 19, and consisting of two flanges - clamps 20 (Fig. 7), fixed between themselves by fasteners 21 (Fig. . 1, 2, 4), for example, in the form of screws with nuts.

Each flange - clamp 20 (Fig. 7) is made of a single plate with high electrical and thermal conductivity, for example, rectangular in plan view, with two holes 22 in opposite corners for fasteners 21 and a central hole 23, for example, of a cylindrical shape adjacent to him symmetrical grooves 24 (Fig. 2, 7), for example, a U-shaped. In addition, each flange - clamp 20 contains at least one mounting tab 25 (Fig. 1, 4, 7), made, for example, L-shaped, and which is its continuation. Mounting tab 25 is made with mounting hole 26 (Fig. 7) for fixing one or more conductive wires 5 therein, for example, by soldering.

Along the contour of symmetrical grooves 24, the flanges - clamps 20 are additionally rigidly fixed by soldering to the surface of the flange - contact 19, which provides additional electrical and mechanical contact of the conductive contact - clamp 3 with the flange - contact 19 of the device 4, as well as conductive heat removal from its surface.

Flanges - clamps 20 of the conductive contact - clamp 3 are fixed to each other so that their mounting tabs 25 are located next to each other and deployed in different directions to ensure the manufacturability of installation and wiring of the conductive elements 5 (Fig. 1).

The assembly of the fastening and cooling device of the active device is as follows.

On the flange - contact 19 (Fig. 6) of the device 4 install the flanges - clamps 20 (Fig. 7) of the conductive contact - clamp 3 and fix them together by fasteners 21 in a position in which their mounting tabs 25 are placed next to each other and deployed in different directions (Fig. 1).

Along the contour of the symmetrical grooves 24 (Fig. 2, 7), the flanges - clamps 20 are additionally rigidly fixed by soldering, providing reliable electrical and mechanical contact, as well as conductive heat removal from the surface of the device 4.

In the hole 26 (Fig. 7) of at least one mounting tab 25, one or more conductive wires 5 are soldered (Fig. 1).

The peripheral contact 18 (Fig. 6) of the device 4, as the most heat-generating element, is placed in the elastic terminal clamp of the bracket 1 (Fig. 5) and fixed with a clamp 7 by means of at least one clamping element 13 (Fig. 1) located in coaxial cylindrical holes 12 of the legs 8, providing conductive heat dissipation from the surface of the device 4, as well as reliable electrical and mechanical contact.

At least one mounting hole 17 (Fig. 5) of the bracket 1 solder one or more conductive wires 5.

The bracket 1 is fixed to the panel 2 by means of fasteners 16 (Fig. 2, 3) screwed into the threaded holes 15 in the protrusions 14 (Fig. 4), made on its outer side surface.

The manufacture of an attachment and cooling device for an active device does not require the use of unique materials and special technologies, so it can be repeatedly reproduced in industrial production.
