Definitions

  • the invention relates to a method for producing tools for unlocking cable connections.
  • the invention also relates to a tool for unlocking cable connections with a shaft which is provided with at least one unlocking pin.
  • the cable end is usually connected to a brass contact.
  • the plug contacts are held in a plug socket by diametrically opposite latching tongues, wherein the latching tongues can be attached to the plug contact or the plug socket and the opposite parts of the latching connection are attached to the other part.
  • the connections formed in this way cannot be broken without the use of tools. This represents 2- or 4- Core plugs are usually not a problem.
  • the non-destructive loosening of the connections is desirable in order to keep the exclusion rate of the cable harnesses as low as possible.
  • Unlocking tools are known for non-destructive loosening of this plug connection.
  • the tool is inserted into the corresponding hole in a plug socket past the plug contact.
  • unlocking pins come into contact with the latching tongues and press them out of their latched position, so that the wire can be pulled out of the plug socket together with the plug contact.
  • the known unlocking tools have a handle with a shaft.
  • the shaft has a circular profile.
  • An end part adjoins the shaft, which is provided with diametrically opposite unlocking pins which extend in the extension of the shaft to flat-ground ends.
  • End part is formed in that material of the shaft is removed in sections, so that the unlocking pins are formed by a recess in the end part.
  • an unlocking tool is known from DE 94 1 1 537 U1, which has a shaft.
  • the shaft has a round or polygonal cross section and is made of a suitable material such as brass, steel, light metal or plastic. From an end face at the free end of the shaft, two opposite bores extend into which unlocking pins are firmly inserted, for example by press fitting or gluing.
  • the unlocking pins are made of metallic material, for example brass, steel or light metal.
  • a diametrical slot extends from the end face of the shaft and serves to receive a protruding contact tongue.
  • an unlocking tool is also known in which the head of the tool can be rotated relative to the handle.
  • the known unlocking tools have the disadvantage that the recess or slot provided is milled and ground from the full material of the shaft and then polished. As a result, the inside of the pins have a high surface roughness caused by milling and grinding. This inevitably leads to damage to the contacts. Furthermore, the penetration depth is limited by the internal machining of the tools. In addition, the formation of the unlocking pins by separate pins, which are inserted into the end face at the free end of the shaft, is complex. This is because it is necessary to provide bores. The drilling of the bores and the production of the pins themselves and their insertion into the bores make the manufacture of the unlocking tools labor-intensive and thus increase the costs.
  • the invention seeks to remedy this.
  • the invention has for its object to provide a method for producing tools for unlocking cable connections, which significantly simplifies the manufacture of the unlocking tools and thus leads to faster and cheaper manufacture of the tools.
  • this object is achieved in that a spring steel is used that is cut to length, and that the cut spring steel is pressed into a sleeve and crimped onto the sleeve.
  • a method for producing tools for unlocking cable connections is created, with which the tools can be produced in a short time.
  • material savings are created.
  • the advantages mentioned lead to a significantly cheaper production of the tools.
  • machining the spring steel is not necessary. As a result, the roughness depth is low, so that there is no damage to the contacts. There is also no limit to the penetration depth.
  • the spring steel is drawn into a U-profile and bent.
  • a tool for unlocking cable connections can be created in a simple, quick and at the same time inexpensive manner, which has two unlocking pins.
  • the free ends of the spring steel are ground. By grinding the free ends of the spring steel, it is possible to change the contour of the spring steel and thus to allow the tool to be adapted to the cable connections to be loosened in each case.
  • the invention also has for its object to provide a tool for unlocking cable connections that is inexpensive to manufacture and at the same time stable. According to the invention, this object is achieved in that the shaft is formed by a sleeve into which a spring steel is pressed and at least one unlocking pin is formed at the free ends thereof.
  • an unlocking tool is created which is inexpensive to manufacture and flexible at the free ends of the spring steel, so that the unlocking pins are prevented from breaking off.
  • making the tool from one piece makes it more stable.
  • the spring steel is bent in a U-shape. This creates an unlocking tool with two unlocking pins. Since the tool is also made from one piece here, it is inexpensive to manufacture. It also has a high level of stability, a low roughness depth and an unlimited penetration depth.
  • the spring steel advantageously has a square cross section.
  • the smooth outside is supported broadly on the housing of the cable connector when the cable connection is unlocked.
  • the outside of known tools is round, so that the tool is only supported on the housing with a small area, which can lead to the housing breaking.
  • An embodiment of an unlocking tool produced by the method is shown in the drawing and is described in detail below. Show it:
  • Figure 1 is a partial view of an unlocking tool in an enlarged view
  • 2 shows the partial view of an unlocking tool in an enlarged view with U-shaped spring steel
  • FIG. 3 shows the partial view of an unlocking tool in an enlarged view in another embodiment.
  • the unlocking tool chosen as an exemplary embodiment has a shaft 1 which is formed by a sleeve. One end of the shaft 1 is pressed into a handle 2. However, the unlocking tool can also be used without the provision of a handle. At the end facing away from the handle 2, a spring steel 3 is pressed into the shaft 1.
  • the shaft 1 has a round cross section.
  • the sleeve forming the shaft 1 is a simple sheet metal sleeve, since this enables the unlocking tools to be manufactured cost-effectively. However, it is also possible to use other materials for the sleeve forming the shaft 1, if this is desired.
  • the handle 2 is designed in a manner known per se. At its end facing the shaft 1, a flange-like finger guard 21 is provided, which is followed by a constriction 22. Following the constriction 22, the handle 2 - not shown - has a substantially square cross-section which forms the head of the handle.
  • the handle 2 can be made of wood or plastic his. The design of the handle from several different materials is also conceivable in order to enable improved handling of the handle.
  • the spring steel 3 has a square cross section.
  • the spring steel 3 is dimensionally rolled in width and height.
  • the use of spring steel with a round cross section is possible.
  • the choice of the cross section of the spring steel depends essentially on the design of the plug contacts, which are to be solved with the help of the unlocking tool.
  • the spring steel 3 is straight.
  • the spring steel 3 is bent in a U-shape.
  • the spring steel 3 is pressed into the shaft 1; in the case of the U-shaped spring steels of FIGS. 2 and 3, the pressing takes place in the region of the bend.
  • the pressing causes a tongue-like, flattened region 11 at the end of the shaft 1 facing away from the handle 2.
  • the spring steel 3 has ground ends 31.
  • the spring steel 3 is provided with a taper 32 at its ends on the sides facing one another. The taper 32 ends in a shoulder 33.
  • the free ends of the spring steel 3 are formed without additional shapes. The design of the free ends of the spring steel 3 depends on the plug contacts to be released in each case. In addition to the variants shown in the figures, a large number of configurations are conceivable.
  • the or the free ends of the spring steel 3 form the unlocking pins.
  • Their shape is determined on the one hand by the shape of the cross section of the spring steel 3, and on the other hand by the processing steps that are carried out at the ends.
  • the spring steel 3 which is usually rolled up on a roll, is unwound and pulled through a straightening bracket in order to eliminate the bending of the spring steel caused by the rolling up. The spring steel 3 is then cut to the desired length.
  • the spring steel 3 is drawn into a U-profile and bent over if a tool is to be produced according to the exemplary embodiments according to FIGS. 2 and 3. It is then pressed into a sleeve that forms the shaft 2 and crimped onto the sleeve.
  • the spring steel 3 is then deburred and ground to size. So-called vibratory grinding is used for grinding, in which a compound made of stones or glass beads, for example, is filled with a liquid polishing paste and possibly water together with the tools in a drum, which is then set in rotation.
  • deburring which is all-round deburring, sharp edges on the free ends of the spring steel 3 are eliminated in order to avoid damage to the contacts when using the tools.
  • the free ends of the spring steel 3 are ground. In this way, for example, the ground ends 31 or the taper 32 with shoulder 33, as shown in FIG. 3, can be produced.
