Definitions

  • the invention relates to electrical round plug contacts with a miniaturized round plug-in sleeve having a spring and a miniaturized round plug pin.
  • a circular spring sleeve having an over-spring which has two contact spring arms, on which two over-spring arms press from the outside.
  • the contact spring arms and the spring arms are not distributed symmetrically around the circumference, so that only a one-sided contact force can be guaranteed.
  • This circular socket is not suitable for a miniaturized design because the asymmetrically acting spring forces do not result in reliable contacting.
  • the over-spring has locking spring arms which are intended to engage behind a locking edge in a connector housing.
  • the detent spring tongues are a hindrance when used in a lockable connector housing, because they at least make it difficult to remove the circular plug-in sleeve from the housing after unlocking and would also destroy a rubber seal when pulled out, for example in the insertion opening of a chamber of the plug housing is appropriate. It is also almost impossible to arrange snap tabs on miniaturized circular receptacles.
  • EP-A-0 108 878 discloses an over-spring round piercing sleeve with a cylindrical spring arm base, at the front end of which spring arms are connected.
  • circular pins which have a crimp area lined up in the longitudinal direction, followed by a connecting web and then a support area and a hollow cylindrical round pin with a rounded tip.
  • the known circular pins are not suitable for a miniaturized embodiment and for use in a lockable connector housing, because the transition zones between the crimp area and the support area and between the support area and the round pin do not have sufficient strength against bending moments.
  • US-A-4 070 088 discloses a piercing pin with a contact area designed as a spring plate.
  • a lockable connector housing with two side walls, two end walls and housing chambers separated by chamber walls.
  • At least one chamber wall which is aligned parallel to the side walls and has holes aligned in the longitudinal direction for the passage of a locking slide, runs from one end face to the other end face.
  • the bar-like locking slide can be inserted into the connector housing through a corresponding end wall hole. It has laterally projecting cams which, when inserted, protrude into the interior of a chamber and engage behind an edge or the like of a plug-in sleeve or a plug-in pin, so that the plug contact is secured in the chamber of the plug housing against being pulled out.
  • plug contacts that are already crimped onto electrical conductors require great care and effort.
  • the plug contacts sit loosely in one chamber and do not find any in the chambers Resistance against pulling out or falling out and only the cams of the inserted locking slide ensure this resistance.
  • the known plug contacts which can be inserted into the housing chamber usually have a sharp-edged cutting edge which is engaged by a cam of the locking slide. When pulling out the plug contact, this sharp edge can destroy the rubber seal.
  • the known plug contacts also have other sharp-edged projections, which can destroy the rubber seal even when the plug element is inserted into the chamber of the plug housing.
  • the object of the invention is to provide circular plug-in contacts in a miniaturized embodiment which ensure very good electrical contacting and are very sturdy and preferably also have a good positive fit in a housing chamber and enable pre-locking when inserted into a housing chamber before the locking slide is inserted.
  • the plug contacts should not have any sharp-edged projections on the side.
  • the miniature version of the pin 1 rolled from a stamped sheet metal part is e.g. 16 mm long and has a crimp area 2, a hollow cylindrical base area 3 and a round pin-shaped hollow cylindrical plug or contact area 4 with a tapered tip 5.
  • the outside diameter of the contact area 4 in the miniature version is e.g. 1 mm, as can be seen from Fig. 2.
  • the stability against bending moments is expediently ensured by a short cylindrical transition area 6 between crimp area 2 and base area 3 and a step 7 between base area 3 and plug-in area 4, the edges 8 and corners 9 of which are rounded, the outer diameter of base area 3 being larger than the outer diameter of the contact area 4 and the transition area 6 and the outer diameter of the transition area 6 is larger than the outer diameter of the contact area 4.
  • This configuration or gradation of the areas 4, 3 and 6 results in a very high resistance to bending moments.
  • the area of the base area 3 adjoining the transition area 6 is formed as an outwardly pressed bead 10 with a semicircular cross section, so that there is a relatively large undercut or a relatively deep undercut for the transition between the bead 10 and the transition area 6 Step with an embossed transition, which makes the shaping considerably easier and also provides a relatively large annular locking surface 11 and also makes it possible to create the transition region 6 in a cylindrical and embossed manner and with a relatively large outer diameter.
  • a plurality of plug pins 1 can be inserted into a pin housing 12 of rectangular cross section of an electrical connector having a pin housing and a sleeve housing 63.
  • the pin housing 12 consists of the pin trough 13 and the chamber housing 14, which are arranged one above the other.
  • the pin pan 13 has a bottom wall 15, two parallel side walls 16, 17 and two end walls 18, 19. Holes 20 are made in the bottom wall 15 perpendicular to the bottom surface plane 15a, each of which is penetrated by the contact area 4 of a plug pin 1.
  • the chamber housing 14 arranged under the pin trough 13 has side walls 21, 22 which run parallel to the side walls 16, 17 of the pin trough 13, offset somewhat inwards, so that a step edge 23 is formed in each case.
  • the side walls 21, 22 are delimited frontally by the end walls 24, 24a. Parallel to the side walls 21, 22, a longitudinal chamber wall 25 is provided in the longitudinal center and a plurality of transverse chamber walls 26 are provided transversely thereto, so that essentially rectangular chambers 27 for pin contacts are formed.
  • the bottom web connecting the U-legs is arranged just above or at the level of the floor surface level 15b, elastically pivotable outward locking webs 29 are introduced in the region of each chamber 27, the bottom side with a is directed towards the chamber interior, rounded, protruding into the interior of the chamber with a chamfer 31.
  • the holes 20 widen in a step-like manner in the direction of the chambers 27 towards the holes 20a in such a way that the holes 20 can receive the contact areas 4 approximately in a form-fitting manner and the holes 20a can accommodate the base areas 3 of the plug pin 1.
  • the bead 10 of the plug pin 1 can be supported directly on the base area 15b on the base area side or is arranged above the base area 15b and is overlapped by the latching lug 30 on the transition area side.
  • a recess 32 extends from the end wall 24a through the longitudinal wall 25 and the transverse walls 26 to the end wall 24, in which a width-shaped locking slide 33 can be inserted and pulled out.
  • the slide 33 is adapted to the cross-sectional shape of the recess 32 and, as is known per se, has locking cams 34 projecting laterally on both sides into the chamber interior, which are arranged opposite the latching lugs 30 in the inserted state of the slide and have approximately the same cross-sectional shape as the latching lugs.
  • the locking cams 34 also overlap the bead 10 of the pin 1 (Fig. 11).
  • pins 1 can be inserted into the chambers 27 if the slide 33 is not in the housing or assumes a position in which the cams 34 do not protrude into the interior of the chambers. Since the pre-locking bars 29 engage behind the bead 10 of the pin 1 with their latching lugs 30, a type of pre-locking is formed, but this can be lifted again if the pin 1 is pulled with the appropriate force against the spring force of the pre-locking bar 29. The pre-locking webs 29 make the insertion and exchange of plug contacts considerably easier by holding the plug contacts used.
  • the circular plug-in sleeve 35 has a crimp area 36, a cylindrical short transition area 37, an adjoining bead 38 with an annular locking edge 39 and a somewhat conical tapering contact area 40.
  • the contact area 40 begins after the bead 38 with a cylindrical spring arm base 41, the diameter of which is larger than the diameter of the transition area 37.
  • the contact area 40 has a butt seam 42 in the longitudinal direction.
  • a circular punch 43 is made in the area of the butt seam 42; a further second circular punch 44 is located opposite in the spring arm base 41. From the circular punch 43, 44 wedge-shaped slots 45 extend forward, which converge towards the end of the contact area 40 or the circular mouth 46, so that two opposing Spring arms 47, 48 result.
  • the end region 49 of the spring arms 47, 48 is bent inwards towards the plug-in opening 46 and cut out in such a way that the circular plug-in opening 46 is formed, the diameter of which corresponds to the outer diameter of the plug-in region 4 of the round plug-in pin 1.
  • a rectangular punched-out 50 is made in the spring arm base 41 between the punched-out 44 and the bead 38, the purpose of which is explained below.
  • each spring arm 47, 48 a longitudinally extending, approximately rectangular punched-out 51 is made in the spring arms, each beginning approximately at the height of the punched-out 43, 44 and ending a bit in front of the mouth 46 with an edge 52.
  • a short incised flap 53 which extends to the spring arm base 41 and has a width corresponding to the width of the punched-out portion 51, is connected, which is bent in the shape of a criss-cross to the interior of the contact area 40, which results in a cross-sectionally shaped abutment web 54 (FIG. 15), the latter Function explained below.
  • the spring arm webs 55, 56 of each spring arm 47, 48 resulting from the punched-out portion 51 are cranked outward by a material thickness in connection with the spring arm base 41, so that a cranking edge 57 results.
  • the round plug-in sleeve 35 is equipped with an over-spring 58, which has a cylindrical over-spring arm base 59, which sits in a form-fitting manner on the spring arm base 41, the butt seam of the over-arm base 59 being arranged opposite the butt seam 42.
  • flaps 60 are provided which are cut in the circumferential direction and are bent into the punched-out 50 and flare the edges of the punched-out 50 so that the spring-over 58 is firmly seated on the circular plug-in sleeve 35.
  • the spring arm base 59 extends from the bead 38 to the cranking edge 57.
  • Two spring arms 61, 62 which extend towards the front and are arcuate in cross section are connected to the spring arm base 59 and extend into the recesses 51 as far as the connecting edge 52, the latter free end engages over the corresponding abutment webs 54 and is supported on them.
  • This configuration of the circular socket 35 results in that the spring 58 does not protrude beyond the contour of the circular socket.
  • the spring arms 61, 62 practically fill through the punched holes 51 gaps in the spring arms 47, 48 almost form-fitting again.
  • the depression of the spring arm base 41 which is created by the offset 57 of the spring arms 47, 48, is filled by the spring arm base 59.
  • an edgeless contact area 40 of the circular plug-in sleeve 35 is formed, which can be inserted, for example, through corresponding holes in a rubber seal or pulled out of the rubber seal without fear that the rubber seal will be destroyed or impaired.
  • the spring arms 61, 62 press on the abutment webs 54 and increase the spring force of the spring arms 47, 48.
  • the spring arms 47, 48 run conically towards one another, which results from the wedge-shaped course of the slots 45. Accordingly, the spring arms 61, 62 are designed to converge accordingly, so that the outer diameter of the spring arm base 59 is larger than the outer diameter of the plug-in area 46a of the spring arms 47, 48 (FIGS. 13, 15, 18).
  • the sleeve housing 63 fits into the pin trough 13 of the pin housing 12 and results in a connector (Fig. 19).
  • the sleeve housing 63 has longitudinal side walls (64, 65, end walls 66, 67 and a bottom wall 68.
  • a longitudinal chamber wall 69 extends parallel to the side walls 64, 65 in the longitudinal center of the sleeve housing 63 from one end wall 66 to the other end wall 67 with the side walls 64, 65 and the chamber longitudinal wall 69 chambers 71 for, for example, circular receptacles 35.
  • the height of a chamber 71 corresponds approximately to the length of a circular receptacle, the contact region 40 being supported in a cylindrical chamber region 72, so that the spring arms 47, 48 have free space 73 for find the feathers outward.
  • U-shaped recesses 28a In the area above the chamber area 72 - as with the pin housing 12 - in the side walls 64, 65 are U-shaped recesses 28a, the bottom webs connecting the U-legs of which are arranged just above the chamber area 72, elastically outwardly locking webs 29a in the area of each Chamber 71 introduced, which are provided in the free end region with a rounded locking lug 30a projecting into the interior of the chamber and projecting into the interior of the chamber with a run-on slope 31a. From the end wall 66 goes through the longitudinal wall 69 and the transverse walls 70 to the end wall 67, a recess 32a, in which a bar-shaped locking slide 33 is inserted and pulled out.
  • the slider 33 is adapted to the cross-sectional shape of the recess 32a and, as is known per se, has locking cams 34 projecting laterally on both sides into the chamber interior, which are arranged opposite the latching lugs 30a in the inserted state of the slider and have approximately the same cross-sectional shape as the latching lugs 30a .
  • the locking cams 34 like the locking lugs 30a, overlap the bead 38 of the circular socket 35 (FIG. 18).
  • the function of the locking slide 33 and the pre-locking webs 29a corresponds to the corresponding parts in the pin housing 12.
  • FIGS. 20 and 21 A different position of the locking slide 33 can be seen from FIGS. 20 and 21.
  • the locking slide has arcuate recesses 34a between the cams 34, the radius of curvature of which corresponds to the radius of curvature of the bead 10 or 38. If the locking slide 33 is in the position shown in FIG. 20, then the recesses 34a are located in the area of the chambers 71. Then only the locking lugs 30 and 30a protrude into the interior of the chamber. After this Inserting a plug contact 1, 35 into a chamber 71 engages behind the locking lug 30, 30a the bead 10, 38 of the plug contact, so that it can no longer fall out of the chamber. When the necessary plug contacts are inserted into the chambers, the locking slide 33 is inserted into the housing in such a way that the locking cams 34 are positioned in the area of one chamber. In this way, the plug contacts are locked. 21 shows this locking position.
  • the described plug contacts according to the invention can also be used in other housings or can be used without housings, in particular the circular plug-in sleeve in the area behind the spring can be designed differently than described above.
  • the stepped shape of the areas 4, 3 and 6 is essential to the invention.
  • the plug contacts can also be combined with other plug contacts, i.e. a plug pin 1 can be plugged together into another socket and a socket 35 with another pin. In this respect, both the plug pin 1 and the plug sleeve 35 have features that justify an invention.
