: - r-gR -, o-- hg.; - ;; | -; -. f -; -: -., -,.,. CABLE BLOCK.

The utility model relates to the field of instrumentation and can be used in the construction of cable blocks of the vehicle wiring harness.

The known design of an automotive fuse, see RF patent for industrial design No. 48552S, MKPO class 13-03, publ. I6.03.200lr., Bulletin RU BPO JVb3. The fuse includes a housing made of electrically insulating material in the form of a vertically oriented parallelepiped, and two plate contacts protruding from the housing.

The known design of the cable block for attaching a fuse, see patent US4921451, MKI5 H01R 13/68, publ. 05/01/90, including a housing made of electrically insulating material, and socket contacts located in the recesses of the housing.

The design drawbacks are the lack of tools that facilitate the orientation of the fuse when inserting its contacts into the socket contacts of the cable box housing and the means that ensure a reliable connection of the block with the fuse during installation of the wire harness on the product and during operation of the wire harness in the product.

For example, when installing a wiring harness on a car (see 1), a fuse may fall out of the cable block of the wiring harness, which will negatively affect the complexity of the assembly process and the condition of the vehicle.

The design of the cable block for connecting several fuses is taken as a prototype of the claimed utility model. Patent US5257951, MKI5 H01R 13/436, publ. 11/02/93 The cable block includes a housing.

made of electrically insulating material and provided with openings for accommodating female contacts, openings for inserting latches for female contacts, female contacts and a female contact lock.

The disadvantages of the design of the prototype is the lack of tools that facilitate the orientation of the fuse when introducing its contacts into the socket contacts of the cable box housing and the means that provide a reliable connection between the block and the fuse during installation of the wire harness on the product and the operation of the wire harness in the product.

The objective of the claimed utility model is the creation of a technologically advanced cable block design for attaching at least one fuse, equipped with tools that facilitate the orientation of the fuse when inserting its contacts into the socket contacts of the cable block body and means that ensure a reliable connection of the block with the fuse.

This problem is solved in the design of the cable block, which includes the block body of electrical insulation material, provided with at least one pair of holes for accommodating the fuse contacts (see, for example, the cable block described in US5257951).

The problem is solved in that the block is equipped with at least two racks to limit the movement of the fuse box, complete at the same time with the block body. In this case, the racks can be made, for example, in the form of profiles of a C- or G-shaped cross section.

The manufacturability of the design is determined by the manufacture of racks by casting along with the block body.

with boeoif

Due to the presence of racks repeating the external contour of the fuse box, the orientation of the fuse is easier when it is installed in a cable block.

Racks prevent the possibility of undesirable effects on the fuse box during installation of the wiring harness on the product and the operation of the wiring harness as part of the product, thereby increasing the reliability of the connection of the fuse to the contacts of the cable block.

The utility model is illustrated by the following drawings.

In FIG. 1 shows the body of a cable block with racks of a C-shaped cross section.

In FIG. 2 shows the body of a cable block with struts of an L-shaped cross section.

To implement the utility model, the housing 1 of the cable block (see Fig. 1, 2), made of an insulating material, for example, thermoplastic plastic, and provided with at least one pair of holes 2 for accommodating the contacts of the fuse, additionally provide at least at least two racks 3, 4 to limit the movement of the fuse box.

Racks 3, 4 are cast at the same time with the housing 1. In this case, the racks can be made in the form of profiles with a C-shaped cross section (see Fig. 1) or a L-shaped cross section (see Fig. 2).

When assembling the wiring harness, the ends of the wires pressed into the socket contacts are inserted into the holes 2 of the housing 1 of the cable block. Socket contacts are fixed in the holes using clamps similar to the clamps of the cable blocks of the patent US5257951 (Fig. Not shown).

Installation of a fuse is carried out by introducing the fuse body into the space bounded by the racks 3, 4 of the block, and by recessing the plate contacts of the fuse in the socket contacts of the cable block.
