Definitions

  • the invention relates to a plug connection for producing an electrical connection, in an electrical device or the like, with at least two releasably connectable contact partners, which are electrically conductively connected to current-carrying means such as electrical lines or the like.
  • Electrical plug connections for example formed by a flat plug and a plug-in sleeve fitted thereon, are widely used, for example, in electrical devices, controls or the like.
  • this type of electrical contacting in the sense of quality assurance of the devices equipped with this type of contacting, the function of each contacting occurring therein can only be guaranteed for all functions of the device in question.
  • Such comprehensive, so-called 100% inspections are extremely time-consuming and therefore extremely cost-intensive.
  • Inexpensive inspection measures such as a visual inspection or the like, have so far not been expedient in the case of electrical plug connections in view of the high quality standard of electrical devices, since it cannot be ensured that the electrical contacting of the two is reliably guaranteed, despite the visually properly assembled electrical contact partners.
  • the invention has for its object to avoid the disadvantages of the prior art with simple design measures.
  • At least one of the contact partners is at least partially provided with means whose origin looks and / or the original color changes visibly from a predetermined temperature threshold, the temperature threshold being selected such that it lies below the destruction temperature of the contact partners and / or the current carrying means.
  • a reliable test which can be reduced to an inexpensive visual test is a test of electrical plug connections provided when electrical devices are in operation. After the means applied to at least one of the contact partners have responded, an electrical plug connection with inadequate electrical contact between the assembled contact partners can be determined directly and without error, even by so-called training staff for quality assurance. In this way, the risk is easily avoided that, due to a lack of electrical conductivity between two contact partners assembled to form an electrical plug connection, an electrical device reaches an end user and the inoperability of the device must be determined there. In addition, the choice of the response temperature of the means prevents the electrical / electronic components of the device from being destroyed and thus its damage.
  • a lack of electrical contact between two contact partners of an electrical plug connection can be determined particularly easily and reliably in the course of a visual inspection if a provision is made according to a preferred embodiment of the subject matter of the invention that the means are designed as color codes, the color of their origin after reaching the temperature threshold turns.
  • the means are designed as color codes, the color of their origin after reaching the temperature threshold turns.
  • a color change is always particularly well recognizable due to a lack of electrical conductivity between the contact partners if, according to a further preferred embodiment of the subject of the invention, it is provided that the color code is arranged on a plug-in sleeve of the plug connection designed as a contact partner. Due to the fact that the color code is particularly suitable for visual inspection as part of quality monitoring, even with a large number of electrical connectors to be tested with a high throughput rate, each of the connectors can still be inspected reliably in order to detect a malfunction of the electrical contact ,
  • the color code on the receptacle is particularly easy to apply with the largest possible area for a particularly effective and safe visual inspection if, according to a next advantageous embodiment of the object of the invention, it is provided that the color code is formed in strips and is arranged outside the overlap area of the two contact partners in the longitudinal direction of the receptacle ,
  • two strip-like color identifiers are provided on the plug-in sleeve, both of which are arranged outside the overlap area of the contact partners.
  • a color change for a test person By attaching two color codes provided for a color change, a color change for a test person, indicating a lack of electrical contacting of the contact partners assembled to form an electrical plug connection, can also be determined with a high degree of probability even if the plug connection is poor at producing an electrical connection visible place inside an electrical device.
  • the color coding on the plug-in sleeve which is provided twice, also significantly reduces the possibility that the color coding is covered by other components and is therefore not visibly recognizable and verifiable.
  • the color identifier suitable for a color change is arranged on the plug-in sleeve at least difficult to remove.
  • a permanent attachment of the color code suitable for the color change ensures that it remains reliably present on the socket even after all assembly work has been completed as part of a production run of an electrical device, and thus a color change can be reliably checked between the two contact partners if there is no electrical conductivity.
  • a fault in an electrical plug connection with regard to insufficient electrical contacting of the merged contact partners can be recognized particularly quickly and reliably if, according to a last preferred embodiment of the subject of the invention, it is provided that the color code after its color change has at least approximately the color of a signal color.

  • FIG. 2 shows the electrical plug connection according to FIG. 1, in a sectional view, according to the section line II - II,
  • Figure 3 shows the electrical connector according to Figure 1 after a color change of the strip-like markings on the
  • Figure 4 shows the electrical connector according to Figure 3 in a sectional view along the section line IV - IV.
  • an electrical plug-in connection 10 which is produced by two interleaved contact partners, is shown, one in the exemplary embodiment shown here has a flat profile socket 11.
  • This has a line holding web 12, at the free end of which adjacently located line brackets 13 are seated, which are formed by a lateral extension of the holding web 12 rolled up approximately to a circular ring contour.
  • the line holding web 12 has contact holders 14 which, like the line holders 13, are formed by lateral cantilevers of the line web 12 rolled up to form an approximately circular ring contour.
  • the line brackets 13 are used for fastening in the present case formed as plastic-coated cable strands 15 electrical lines which are gripped by the line brackets 13 on their plastic sheathing used for their insulation for the purpose of fastening them to the line holding web 12.
  • the wire strands 15 have wire cores 16, which are surrounded for their electrical insulation with the plastic sheath, which is removed at the free end of the wire strands 15, whereby the wire cores 16 for electrical contacting of the wire strands 15 are fixed in electrical contact within the contact holders 14.
  • the plug-in sleeve 11 has a sleeve section 17 which comprises a support and guide section 18 with a flat profile in cross section.
  • the support and guide section 18 has a contact surface 19 which serves for electrical contacting, and contacting sections 20 which essentially have a semicircular cross section which is formed by rolling in laterally protruding projections which are integrally formed on the support and guide track 18.
  • the contacting sections 20 have holding elements 21 which are formed by the free ends of the rolled-up lateral projections.
  • the free end of the holding elements 21 is arranged at a distance a above the bearing surface 19, the distance a being set to a predetermined dimension within the scope of the usual manufacturing tolerances.
  • strip-like color identifiers 22 extending in the direction of the contacting sections are provided on the contacting sections 20, almost over their entire length.
  • the coating can also be designed such that, in addition to a color change, a shape or shape change also occurs, the Coating can also be designed such that only a change in shape and / or shape is effected when a predetermined temperature threshold is exceeded.
  • the plug-in sleeve 11 serves to receive a contact partner designed in the present case as a flat plug 23, which, as is particularly evident from FIGS. 1 and 3, forms an overlap region B with the contact surface 19 with its contact section 24 in the inserted state and which, as shown in particular in FIG. 2, is pressed in a fully functional contact between the two contact partners by the holding elements 21 on the plug-in sleeve 11 for its electrical contacting against the bearing surface 19.
  • the tab 23 inserted for its electrical contacting in the socket 11 is arranged both at a distance from the contact surface 19 and from the holding elements 21, as a result of which there are electrically insulating air gaps s between the contact surface 19 and the tab 23 as well as between this and the holding elements 21.
  • the air gaps s significantly increase the electrical contact resistance between the flat plug 23 and the plug sleeve 11, as a result of which the plug connection 10 heats up to a temperature which, in the color code 22 shown in FIG. 2 in the initial state, results in a color change, as shown in FIG. 4 is leads.
  • a test person for example as part of a quality assurance, is already clearly shown on the basis of a mere visual inspection that there are contact weaknesses or a complete contact fault in the contact partners 11 and 23 joined to form an electrical plug connection 10.
  • the color identifier 22 can be set to different response temperatures with regard to its material or its chemical composition.
