Due to the limited free area for installation, it is also difficult to securely fix the device. The presented model helps to solve the following technical problem: - the possibility of extending the device in length and / or width by assembling and connecting an unlimited number of cases, using fixing grooves (clamps). The device consists of: a base made of plastic with mounting holes; top cover made of plastic, plastic removable partitions, plastic removable plugs, plastic fixing grooves, metal fasteners: screws, washers, grovers and nuts. other vehicle, from a source of electrical energy to one or more devices, and to avoid overloading the wiring, power surges and short circuits.

Description

The field of technology.

The presented model refers to switching devices for the distribution of electrical energy from a source to one or more devices, and is also used to protect the power supply wiring from possible short circuits or overloads of electrical networks.

The predominant field of application is car audio systems, power distribution of power supply in vehicles with a power supply of 12-24 volts.

State of the art.

Power distributors for car audio systems and power supply systems in vehicles with an integrated fuse holder are widely used, which allow switching power wiring and avoiding damage to devices connected to the power source due to overloads or surges in electrical voltage. The disadvantage of this type of switching device, when creating complex car audio systems and electrical wiring with the connection of multiple devices, is the limited free area for installation, the need to use several devices.

Due to the limited free space for installation, it is also difficult to securely fix the device.

The presented model helps to solve the following technical problem:

- allows to build up devices in length and / or width, by assembling and connecting an unlimited number of cases, using fixing grooves (clamps) (Fig. 17).

Disclosure of the utility model.

The presented utility model includes two types of cases: two-section (Fig. 1) and three-section (Fig. 8). Designed to perform the function of a power distributor with a fuse holder, which, due to the versatility of the design, can perform both the function of a power distributor and a fuse holder, and can also be assembled into a group of any number of fuse holders and (or) power distributors using retainers.

The device consists of: a base made of plastic with mounting holes; top cover made of plastic, plastic removable partitions, plastic removable plugs, plastic fixing grooves, metal fasteners: screws, washers, grovers and nuts.

The presented model is used when laying power cables, in a car audio system or for distributing power in any other vehicle, from a source of electrical energy to one or more devices, as well as to avoid wiring overload, electrical surges and short circuits.

The universal design of the case allows it to be implemented as a power distributor, with the ability to increase the width or length of the device, by connecting several devices to each other using plastic connecting grooves-retainers. In this case, it is possible to install a metal jumper made of copper or brass instead of the fuse to reduce losses in the transmission of current and voltage, which is fixed with screws. Also, a metal jumper makes it possible to connect plastic platforms, from any convenient side, providing additional rigidity of the connection.

The presence of movable, removable partitions prevents possible closure of contacts, as well as the ingress of foreign objects, and plastic removable plugs prevent the ingress of dust and moisture.

In the upper protective cover of the device, on both sides there are vertical recesses, thanks to which, using a screwdriver or a plastic remover, you can safely dismantle the cover for servicing the device, which is assembled between adjacent devices.

The upper protective cover is fixed to the main platform thanks to the wedge-shaped grooves that are inserted into the special holes in the base.

Also, when using the device as a power distributor, it is possible to connect to it an unlimited number of fuse holders or distributors, reliably interconnected, thereby creating the possibility of building complex connection systems. Or combining several fuse holders or distributors into a system of any configuration, both connected and not connected by conductive elements to each other.

Thus, a distinctive feature of this utility model is: the ability to use the same device to perform the functions of a distributor (distributor) and fuse holder, and the construction of complex power distribution systems by building up and combining several devices.

The material for the body, connecting grooves, and also movable partitions of the device is plastic.

A metal jumper, fuse and (or) terminals are fixed in the device case using fasteners such as screws and nuts.
