D iJ-t JLJ D.Ts.TS i DKZ The invention relates to the field of installation of electronic radio devices, namely to the device of templates for making wiring harnesses. A known template for the manufacture of wiring harnesses comprises spring clips of a group of wires mounted on its plane and tracing studs. When laying the wire into a bundle, one end of it is embedded between the coils of the spring and thereafter placed on the template between the tracing studs, and the other end of it is inserted into the spring of the other fixture {1j. The disadvantage of this template, which has spring clamps on the surface, is that the end and corner tracing pins interfere with the effective use of mobile means of mechanization in subsequent operations — when bandaging, viscous, braiding, etc. Closest to the invention is a template mounting device for fastening wires that contains at least a coil spring, a string located inside it and a flat rod with sharp edges, the spring enclosing the string and the rod with the possibility of longitudinal movement relative to them 2J. A disadvantage of the known device is that the mounting device used in it fixes only the ends of the wires by winding them onto a flat rod, and the longitudinal movement of the springs does not allow the wires to be fixed in a predetermined place. The aim of the invention is to expand the technological capabilities and increase the reliability of fixation. The goal is achieved by the fact that the template for the manufacture of harnesses containing wire clamps, made in the form of springs installed parallel to the template plane with a centering element, is provided with an additional base installed parallel to its lower plane, prism-shaped springs are made in the template and mounted on an additional base through the indicated grooves of the Jablon, the centering element of each clamp is installed with a gap between the template and to olnitelnym base and is attached to the middle of the spring coil. FIG. 1 shows a template for making wiring harnesses, top view; in fig. 2 — node I in FIG. I; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - spring. In the template 1, at the location of the latches, the through grooves 2 are made through which prismatic springs 3 are passed, strung on the centering rod 4. Template I is provided with an additional base 5 installed parallel to its lower plane, and the centering element of each retainer is installed with a gap and is attached to the middle turn of the prismatic spring 3, while the attachment point serves as the starting point of reference when laying. In the places of rotation of the main branches from the trunk of the harness b, rotary rods 7 are installed. Template 1 is installed with the possibility of vertical movement relative to the plane of the additional base 5. The wires are laid in the harness using the proposed template as follows. The wire laid in the harness with a folding head (not shown) or manually fixed in the middle turn of the spring 3, which is attached to the centering element 4, and laid out along a predetermined route on the template plane I, followed by its fixation in the final spring 3. Laying the wire in the harness 6 can be carried out in a continuous manner or in individual measured pieces of wires with the location of the bundle shaft between the springs 3. After the formation of the bundle is completed, the template 1 is lifted relative to the additional bases 5 or 1/3 the height of the spring coil 3 and lowered to its original position, which allows the subsequent operations to produce: banding, structure knitting, braiding, etc. When the template I is raised to the full height of the coil of the spring 3, the finished harness is removed. Supplying the template with an additional base and making the spring of each prismatic-shaped clamp allows the manufacture of harnesses with a more complex configuration, which expands technological capabilities and improves the reliability of fixing individual wires, the main trunk of the bundle and its branches.
