Description

The utility model relates to electronics and electrical engineering, in particular to devices for mounting electronic equipment, and can be used in the design of modular equipment installed on panel panels.

Known metal rail TH35 (DIN rail), made in the form of a metal profile of a special shape with a width of 35 mm This rail was developed by the German Institute for Standardization (DIN) and adopted by the International Electrotechnical Commission (IEC), adopted as the European Standard (EN) and as the national standard in Russia (GOST R IEC 60715-2003). It is known to use a DIN rail for mounting various modular equipment.

Known housing for mounting on a mounting rail (AS No. 0780939, BOPLA (Germany), publ. 06/25/1997), Housing for mounting on a mounting rail). This design has a transverse spring latch on the rear wall of the housing. To install the housing on the mounting rail, it is necessary to pull off the spring latch, install the housing, release the latch, which returns to its original state, as a result of which the housing is fixed on both sides of the mounting rail.

This case does not exclude the possibility of longitudinal movement of the equipment along the DIN rail. To prevent longitudinal movement, lateral clamps are used.

The closest technical solution to the invention is a device for mounting on a DIN rail (DIN rail latching system and method) (AS No. 1648064, Rockwell Automation, publ. 04/19/2006 - prototype). The fastening device consists of two transverse gate valves that fix the device on both sides of the DIN rail. The mounting method is to move the valves that have protrusions. When installed on a DIN rail, the valves move to the extreme position, the equipment is installed, the valves move to their original position, getting protrusions into the profile of the DIN rail.

This mounting method does not exclude the possibility of longitudinal movement of the equipment along the DIN rail.

The utility model is aimed at solving the problem of simplifying the design of the device, eliminating the longitudinal movement of equipment, combining various modular equipment, ensuring the accuracy of fastening and improving the ease of installation of equipment.

This is achieved by the fact that the housing of electronic equipment is used, which has a removable plastic or metal sliding latch mounted on the rear wall of the housing using tabs with protrusions and L-shaped holes, in a recess with beads made to the size of the fixed equipment, and the sliding latch is fixed on the back wall of the housing with fasteners and has grooves at the edges, the device is equipped with a latch and has an eye for moving the latch.

The utility model is illustrated by drawings, in which Fig. 1 schematically shows a mounting device for modular equipment, the rear wall of an electronic device; figure 2 is the same, a retractable latch; figure 3 - installation of a retractable latch on the rear wall of the electronic device, position I; figure 4 - installation of a retractable latch on the rear wall of the electronic device, position II; Figures 5 and 6 show a mounting method on the rear wall of one device of another device.

A device for mounting modular equipment comprises a housing 1 of an electronic device, collars 2, a rear wall 3, protrusions 4, tabs with protrusions 5, a cutout 6, a sliding latch 7.

The beads 2 are made according to the size of the fixed equipment. The sliding latch 7 (looks like a segment of a DIN rail) has an eyelet 8 for moving, cutouts 9 along the edges, L-shaped holes 10 and latches 11. The sliding latch 7 is secured with tabs with tabs 5 on the rear wall of the housing 1. The sliding latch 7 has cutouts 9 along the edges, made under the installed equipment.

The sliding latch 7 has two fixed positions set by the latch 11. To ensure accurate and rigid fastening of the equipment, in the housing 1 there is a recess in the back wall with collars 2 made in accordance with the dimensions of the equipment. On the one hand, the bead has a notch 6 in size of the sliding latch 7 for the possibility of its movement.

The device operates as follows

Another device 12 is brought to the back wall 3 of one device. The fixing method consists in moving the latch 7 to position I (Figs. 5 and 6). The protrusions of the latch 7 fall into the grooves of the device, ensuring reliable fixation of the equipment. The possibility of moving the equipment in the longitudinal direction is excluded with the help of collars 2. This design provides a solid mount for two devices.

The proposed device allows to exclude the longitudinal movement of equipment, to combine various modular equipment, to ensure accuracy of fastening and ease of installation of equipment.
