W The proposed utility model relates to electrical engineering, namely to branching devices with built-in electrical elements, and can be used to simultaneously connect several consumers to the electric network, such as a computer, monitor, copier, fax, printer, audio and video systems. A housing for a line filter is described, described in a multi-unit extension block and containing a base and a cover with an opening for supplying power wires, blind cylindrical sockets with holes for plug pins and earthing contacts, oval shaped blind sockets with holes for plug pins and made on the outside of the cover a protrusion under the jamming filter board having a horizontal platform on which there is a hole for the switch and a marking field, while a protrusion under the jamming filter board tra housing cover configured situated towards the end of the body with an opening for wires pitayushego ramp under the circuit breaker accommodating semioval groove with the through hole therein for mounting electrical circuit breaker automatic button / 1 /.

This design of the housing for the surge protector (multi-unit shoe) allows you to provide in it a device for protecting it from current overloads while simultaneously connecting all the necessary equipment, which increases the durability of the surge protector housing and the reliability of the latter.

However, this design of the housing cover for the line filter

(multi-unit pads) with a protrusion under the noise suppression filter board having an inclined platform with an oval groove and a hole in it for the button of an automatic circuit breaker, complicates its manufacture and installation of such a mains filter housing (multi-pad), and the placement of the button of an automatic circuit breaker in the oval groove of the inclined platform of the protrusion leads to the inconvenience of its operation.

A housing for a line filter is also known, comprising a base and a cover, an opening for the supply wire located in one of the ends of the housing, blind cylindrical sockets with holes for the pins of the plugs made on the outside of the cover, and ground contacts located on the side of the end of the housing with an opening for the supply wires protrusion under the anti-interference filter board with a horizontal surface on which the platform for

markings and a hole for fixing the switch, cylindrical bosses made on the inside of the housing cover with an internal thread for the fasteners of the case and connected to the holes for the plugs of the plugs, hollow cylindrical bosses for fastening the supply contacts of the plugs, the mounting element of the supply wire mounted on the inside of the base of the housing with a gap at the end with an opening for the supply wire, two pairs of bosses for attaching the noise suppression filter board, two groups of transverse partitions for displacements of current-carrying tires, offset from each other and separated by two longitudinal partitions to accommodate an earthen tire, a transverse thrust partition located with a gap with respect to the opposite end of the casing, ten cylindrical bosses for mounting earthing contacts located in places corresponding to the holes for earth contacts on the cover , and mounting holes made on the inner side of the base in places corresponding to the location of the mounting bosses of the cover, The town and two pairs of bosses for mounting the circuit board are located at a distance that ensures the placement of the circuit breaker housing between them during installation, and in the places where the cover and the base are connected, a protrusion and a groove are made to ensure mechanical coupling / 2 /.

the operation of it, leading to a decrease in its durability, since the design of such a housing for a line filter does not provide for the presence of a current overload protection device when several electronic devices with high power consumption are connected to it, as well as the presence of structural elements to protect against damage supply wire, current-carrying and earth tires when they are mounted in the housing.

In addition, the presence in such a case for a line filter of blind cylindrical sockets of the same design, which stipulates the use of only Eurostandards, as well as the inability to mount such a case of a line filter on inclined and vertical surfaces, leads to the inconvenience of its operation and, therefore, limits its functionality.

Also known by construction and closest technical result to the claimed utility housing model for a surge protector, comprising a base and a cover, an opening for a supply wire located in one of the ends of the housing, blind cylindrical sockets with holes for plugs made on the outside of the cover and ground contacts, at least one blind cylindrical socket with holes for the pins of the plugs and a protrusion located on the side of the housing end with an opening for the supply wire Dr. fee

interference suppression filter with a horizontal surface on which there is a rectangular hole for fixing the line filter switch, a marking area for the line filter and an opening for the circuit breaker button located near the marking area on the side of the housing end with a hole for the supply wire, made on the inside side of the housing cover inner deaf bases

an electrical network through a surge protector without turning on or off the plugs of the individual wires of these electrical consumers during their operation and, therefore, improves the usability of the surge protector compared to the prototype.

The presence of additional sites for marking additional switches located on the lower stage of the lid in this way allows for quick identification of an individual power consumer, with the aim of turning it on

electrical network or disconnect from it, which makes it easier

the use of such switches and therefore improves convenience

end 4 of the mains filter housing and is also equipped with a fixed identical cover 45 (see Fig. 2).

The assembly of the proposed surge protector is as follows.

Initially, a supply wire (not shown) is laid in the hole 3 of the base 1 of the mains filter housing, it is fixed in an element 29 for fastening the supply wire, and then it is connected to a noise suppression filter board (not shown), which is screwed to the bosses 30 and 31 bases 1 of the housing. Next, in the longitudinal slots 33 of the transverse baffles 32 and the longitudinal slots 44 of the bridges 43 are laid live conductors (not shown in hell) so that their ends abut the bends 42 of two longitudinal dividers 34, and then the live conductors are connected to the anti-noise filter board. Between two longitudinal partitions

34 lay an earthen tire (to hell, not indicated), which with one

the sides abut against the cover 45, and on the other, into one of the bends 42 of two longitudinal partitions 34, and also connect it to the noise suppression filter board. To the cylindrical bosses 25 of the base 1 of the case, ground contacts (on black are not indicated) of each blind cylindrical socket 7 of the cover 2 are mounted and connected to the earth cover. On the protrusion 5 under the suppression filter board cover 2 of the housing in the hole 18 is fixed to the common switch 19
