A device for connecting electrical cables containing a terminal block located in a housing with a removable cover (AS USSR No. 154307). The design allows the use of four core cables that connect to the terminal bolts. Conductor cables are introduced into the duct through cable entries. The terminal block is made detachable and consists of three plates. The middle plate is used for fastening current-carrying bolts. The bottom plate isolates live bolts from the bottom of the housing.

The disadvantage of this device is the need to provide sufficient space for installation and subsequent maintenance of the connecting device.

The presence of removable partitions, if necessary, allows you to quickly, simply and quickly change the connection diagram of the power wires without performing complex manipulations with them, associated with bending, turning, changing their position relative to the connecting device. Removable partitions can be moved by placing them in accordance with the desired connection diagram, respectively moving the jumper between the contact elements. In addition, the presence of removable partitions allows the use of a standard tool, in particular, a standard torque wrench, for mounting or dismounting power wires. This advantage is provided by the fact that during installation, tightening the nuts, the partitions are removed / absent and, accordingly, do not interfere with the execution of technological operations.

A common mounting unit for partitions also makes it possible to implement the required power circuit connection scheme in the claimed connecting device, since the presence of a common mounting unit allows you to move partitions and a jumper between contact elements in cramped conditions on a vehicle. In addition, a common mounting unit simplifies and speeds up the process of installing and removing partitions and jumpers, allows you to improve the process of servicing the connecting device.

The fastening of the terminal block plate to the box using a detachable connection allows you to implement the required connection diagram in cramped conditions on a vehicle, as if necessary, allows you to remove the terminal block plate from the box, which facilitates the maintenance process associated with a change in the wiring diagram by moving the jumper between the contact elements.

The technical result is also ensured by the fact that the common mounting unit is made in the form of an element in contact with the surface of each partition installed in the working position and equipped with a latch that ensures its stationary position relative to the terminal block plate.

In addition, the technical result is ensured by the fact that the element in contact with the surface of each partition is made in the form of at least one rail, and the latch of its position is made in the form of a threaded connection; and also the fact that the element in contact with the surface of each partition is combined with the inner surface of the lid, and elements of fastening the lid to the box are used as a position lock; and the fact that the element in contact with the surface of each partition is the inner surface of the lid, and the fastening elements of the lid to the box are used as a position lock.

The connecting (terminal) device consists of a box 1 with a removable cover 2. Cable entries 3 are made in the box 1. A terminal block 4 is placed inside the box 1. The terminal block 4 is attached to the box 1 using a detachable connection. It is preferable to use quick-disconnect connections that facilitate mounting / dismounting of the terminal block 4 in box 1 of the connecting device. The box 1 of the device is closed by a cover 2, the position of which is fixed by locks 5.

Box 1 is used as a supporting element and performs two functions: it serves for fastening the terminal strip 4, as well as for attaching the connecting device assembly to the body of the unit or vehicle. Box 1 can be made as a box-like element, as shown in FIG. 1, and in the form of a flat carrier plate (not shown). In the first case, the cover 2 is flat, and in the second case - box-shaped. A possible embodiment of the box 1 and the cover 2 in the form of two geometrically identical conjugate box-shaped elements with a connector along the cable entries 3.

The terminal block 4 is made in the form of a plate 6 with partitions 7 dividing the space between the contact current-carrying elements 8. The terminal block 4 is made of an insulating material. Partitions 7 terminal strip 4 are removable. The pairing and fastening of the partitions 7 with the plate 6, is carried out by means of a common mounting unit, providing simultaneous fixing of all partitions 7, their fixation relative to the plate 6, for example using fixing rails 9.

The plate 6 of the terminal strip 4 can be made in the form of a single part or several parts. The embodiment of the plate 6 is selected depending on the specific purpose of the connecting device, the conditions of its operation, as well as the design of the mount.

When describing the options for the practical implementation of the connecting device, the design of the plate 6 is revealed in the amount necessary to understand the essence of the claimed technical solution.

Each contact element 8 can be made in the form of a bolt 10 with a nut 11 for mounting terminals 12 of current-carrying wires. The bolt 10 is passed through the plate 6, and its head is fixed in the body of the plate 6 to protect against turning the bolt 10.

As a quick-connect terminal block with the box 1 can be used a threaded connection, which is more convenient to implement, for example using screws 13.

The connecting device with removable partitions 7 allows you to quickly change the connection diagram of the current-carrying wires, depending on the need. To change the wiring diagram, it is enough to remove the necessary partition 7 and change the position of the jumper 14 by connecting the necessary contact elements 8. A quick change in the wiring diagram is provided by the presence of a common attachment point for removable partitions 7. The height of the partitions 7, when they are in the working position, is selected from the excess height partitions 7 of the height of the contact element 8.

The common assembly of the partitions is made in the form of an element in contact with the surface of each partition 7, when all partitions 7 are installed in the working position. In addition, the common mounting unit of the partitions 7 is equipped with a latch, providing a fixed position of the latch relative to the plate 6 of the terminal block 4.

The applicant has developed several options for implementing the claimed device, each of which can be applied in the corresponding situation.

In the first version of the partition 7 of the terminal strip 4 are made mushroom-shaped (Fig. 2). In this case, the leg 15 of the partition has hooks 16 made in the form of a slot on the leg 15. In this embodiment, the hooks 16 are oriented outward. The leg 15 of the partition 7 is placed in the transverse slot 17 of the plate 6 .;

In this case, the common fastening unit is made in the form of two longitudinal rails 9 placed on opposite sides of the partitions 7. Each rail 9 is placed in the slot-hook 16 of the partition 7. The fixing of the rail 9 relative to the plate 6 is carried out by screws 18. The holes in the rail 9 for fixing screws 18 are made oblong according to GOST 16030-70, the long axis of which is oriented across the rail 9 (type G, Fig. 2). The length of the oblong holes is selected from the condition of release of the hook 16 when moving the rack along the long axis of the hole. In other words, the length of the oblong hole is equal to or greater than the sum of the diameter of the rail mounting screw and the hook depth 16.

This embodiment of the terminal strip 4 allows you to get the most compact design.

The second variant of the connecting device (Fig. 3) is characterized in that the hooks 16 of the partition 7 are oriented inward, i.e. facing each other, and in the body of the plate 6 of the terminal block 4, longitudinal grooves 19 are made. In this case, when the partition 7 is installed in the working position in the transverse slots 17, the hooks 16 form windows with longitudinal grooves 19 in which the rail 9 is located.

The formation of windows for placement of rails 9 in them reduces the general requirements for fixing the latter relative to the plate 6 of the terminal block 4.

The third version of the connecting device (Fig. 4) is applicable if it is necessary to use supporting elements 20 for current-carrying wires. The rails 9, fixing the position of the partitions 7 are installed on top of the supporting elements 20 and are fixed from movement by screws or nuts 21. Moreover, the holes for the fasteners can also be made oblong.

If there are restrictions on the overall width, the fourth option is applicable (Fig. 5), where the partitions 7 are mounted along their upper end surface. The rail 9, fixing the position of the partitions 7 is placed in the recesses made in the upper part of the partitions 7 and is fixed with screws 22 relative to the plate 6 of the terminal block 4.

If necessary, additional insulation of the rail 9 can be made of insulating material, for example PCB, the required width as in option 5, shown in FIG. 6.

In addition, in the fifth embodiment, the cover 2 of the connecting device can be used as the fixing element. The fixed fixation of the partitions 7 in this case is ensured by their compression by the inner surface of the cover 2 in the direction of the plate 6.

The use of the connecting device in the power circuits of the vehicle is as follows.

The connecting device is usually placed on the body of the consumer of electricity, such as a traction motor or near it. In some cases, additional means are used to protect against penetration into the box of the connecting device of moisture, water, dust, etc. or choose the location of the connecting device, which is guaranteed to exclude the ingress of water and dust into the box of the device.

To install the power circuit, remove the cover 2, release and remove the partitions 7, removing from contact with a common mount.

In the first embodiment, to release the partitions, the screws 18 are loosened and the slats 9 are moved outward within the oblong hole made in the slat 9. When the slat 9 is moved, the latter comes out of contact with the hook 16 of the leg 15, thereby releasing the partition 7. After releasing the partitions 7 they are removed from the slots made in the plate 6.

In the second embodiment of the practical implementation of the connecting device (Fig. 3), the screws 18 are also loosened to release the partitions. The rails 9 are not moved outward, but inward within the oblong hole made in the rail 9. When the rail 9 is moved in the longitudinal groove 19, the latter comes out from contact with the recess of the partition 7, freeing it.

In the third embodiment (Fig. 4), to release the partitions 7, the nuts 21 are loosened. The same applies to the fourth and fifth embodiments of the connecting device.

The developed connecting device allows to increase the reliability of the contact group of the power circuit, reduces the time of maintenance of the device in cramped conditions by facilitating access to the elements of the contact group.
