Definitions
- the invention refers to a splice head for insulated wires of the type used by the telecommunication industry.
- Connectors for the telecommunication industry are know wherein a plurality of insulated wires are connected with electrical contacts.
- German patent DE 39 20 362 it has become known to provide a retaining body with a plurality of insulation displacing contact elements and to have the wires engaged with the contact elements by means of a pressing body so that the contact elements coact with the associated wires while piercing through the insulation thereof.
- the pressing body includes recesses or pockets into which the free ends of the cutting contact elements are plunged. Further, cutting elements are located in the retaining body which cut the projecting ends of the connected insulated wires.
- the splice head comprises accommodation means for a connector, i.e. at least one retaining body and at least one pressing body. It further includes a row of spaced separating fingers on one side of the accommodation means.
- a splice head is associated with the end of a cable or wire bundle, with the individual cores or wires exposed.
- the wires are arranged in the slots between the fingers and aligned with the individual insulation displacement contacts of the retaining body.
- the ends of the insulated wires extending beyond the accommodation means are fixed in a suitable manner until the all of wires has been laid onto the connector. Thereafter, the pressing body is pressed against the retaining body, preferably by a suitable tool, in order to concurrently bring the insulated wires in engagement with the insulation displacing contacts.
- the diameter of the insulated wires may be within a larger range.
- the coil springs are not suited to effectively fix wires of different diameters. Therefore, it is required to replace the springs in case of wires having different diameters.
- the spring is fixed at one end, therefore, the splicing operation has to be always started at this end of the spring.
- the invention provides a splice head for insulated wires, particularly for telecommunications, which is designed to work with and hold wires with different diameters.
- the splicing can be started contemporarenously at both ends of the spring.
- the bar may have a circular cross section so that the spring may slide easily forward and backward.
- an engaging surface is provided somewhat below the bar and is spaced a small distance therefrom which engaging surface is adapted to support the circumference of the spring while it is retained by the 5 bar interiorly.
- the space between the engaging surface and the bar is somewhat larger that the diameter or thickness of the wire forming the coil spring.
- the engaging surface is formed and provides a space with respect to the bar such that in the operational position of the spring the bar engages the spring approximately at the level of the longitudinal axis of the spring.
- the engaging surface extends partially circularly about the bar.
- the bar can be retained by a U-shaped retaining member which according to an embodiment of the invention integrally includes the engaging surface.
- the coil spring need not be replaced in order to fix wires of different diameter sizes. Since the coil spring is loosely arranged on the bar, radial bends at the ends of the spring could be omitted. This facilitates the manufacturing of the coil spring.
- Fig. 1 is a diagrammatic view of a splice head according to the invention.
- Figs. 2 to 4 illustrate the coil spring of the splice head of Fig. 1 in different operational positions.
- Fig. 5 is a cross sectional view through a coil spring of Fig. 2 along line 5-5.
- a splice head 10 is shown retained by retaining means 12 adapted to be manually held or fixed by known fastening means.
- the splice head 10 includes an accommodation means 14 for supporting a connector, not shown, adapted to receive a plurality of insulated wires.
- a connector is for example disclosed by the DE 39 20 367.
- the accommodation means 14 comprises a support plate 16 and two lateral guide elements 18 to keep a connector therebetween which includes at least a retaining body and a pressing body. Two rows of fingers 20 are located on one side of the accommodation means 14.
- a coil spring 22 is located on the opposite side of the plate 16 of the accommodation means.
- the coil spring 22 is retained by retaining means 24. Details of the retaining means and of the coil spring are illustrated in Figs. 2 to 5.
- the retaining means 24 consists of a U-shaped retaining member 26, with the legs thereof retaining a bar 28 of circular cross section.
- the bar 28 is fitted through holes in the legs accommodating said bar or a slot in the retaining means 24 and legs.
- coil spring 22 has a length smaller than the length between the legs or the length of bar 28.
- the coil spring 22 can be freely moved along bar 28.
- the diameter of spring 22 is for example 15 mm, and the thickness or diameter of the wire forming the coil spring 22 is for example 1.5 mm.
- the individual coils 30 or convolutions of spring 22 have a predetermined space therebetween.
- the ends of the wire forming the coil spring are simply cut and not deformed in a particular manner.
- an arcuate engaging surface 34 circular in cross section, is formed in the web 32 of the U-shaped retaining member 26. The most narrow space between bar 28 and engaging surface 34 is slightly larger than the thickness of the spring wire.
- the circular engaging surface 34 extends into or joins with an upper planar surface 36 which would extend parallel to a plane through the axis of coil spring 22.
- the normal distance between surface 36 and bar 28 is larger then the space between engaging surface 34 and bar 28.
- engaging surface 34 is formed and located relatively to bar 28 such that bar 28 engages spring 22 approximately at the level of the longitudinal axis of spring 22 when the spring 22 is in its operational position.
- Figs 2 to 5 it is illustrated how wires 40, 40', 40'', respectively, are inserted into and fixed by spring 22.
- Figs. 2 to 4 make clear that the start of the splicing operation can be selected arbitrarily in that the spring 22 may occupy an arbitrary position between the legs of the U-shaped retaining member 26 at the beginning of the splicing operation. It will be clear from Fig. 5 that apart from the diameter of bar 28, the largest part of the cross section of spring 22 is available for the fixing of wire 40, 40' or 40'', respectively, so that also two or more wires may be inserted between adjacent helical convolutions or coils 30.
