Definitions

  • the invention relates to an electrical connector with a contact pin and a contact sleeve housing.
  • An electrical connector with lockable plug housings which has 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.
  • 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 is suitable for a miniaturized design Not the circular plug-in sleeve, 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 cumbersome when used in a lockable connector housing, because they at least make it difficult to remove the circular connector from the housing after unlocking and would also destroy a rubber seal when pulled out, which is attached, for example, in the insertion opening of a chamber of the connector housing. It is also almost impossible to arrange snap tabs on miniaturized circular receptacles.
  • 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 grimp area and the support area and between the support area and the round pin do not have sufficient strength against bending moments.
  • plug contacts that are already crimped onto electrical conductors (in the known plug housings) requires great care and effort.
  • the plug contacts sit loosely in a chamber and find no resistance to pulling out or falling out in the chambers and only the cams of the inserted locking slide ensure this resistance.
  • the in the housing chambers Known plug-in contacts that can be used 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 a connector with plug housings with a locking slide, in which the insertion and / or replacement of plug contacts is safer and easier.
  • the miniature version of the pin 1 rolled from a stamped sheet metal part and particularly suitable for the connector according to the invention 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 outer 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 grimp 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 designed as a bulge 10 which is pressed outwards and is semicircular in 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 according to the invention, which has a pin housing and a sleeve housing.
  • 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.
  • 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 plane 15b, elastically pivotable outward locking webs 29 are introduced in the region of each chamber 27, the bottom 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 bar-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. 7)
  • 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 locking lugs 30, a type of pre-locking is formed, which can, however, be released again when the pin 1 is pulled with a corresponding 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 inserted.
  • a round plug-in sleeve 35 which is particularly suitable for the plug connector according to the invention, 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 contact area 40 which extends towards the front.
  • 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.
  • 44 wedge-shaped slots 45 extend towards the front, which converge towards the end of the contact area 40 or towards the circular mouth 46, so that two are opposite one another 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 level 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 an abutment web 54 with a hook-shaped cross section (FIG. 22) whose function will be 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 circular 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 which are cut in the circumferential direction and which are bent into the punched-out 50 and flanged the edges of the punched-out 50 so that the spring-over 58 is firmly seated on the circular 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 overlap the corresponding abutment webs 54 and rest 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 edge-free contact area 40 of the circular plug-in sleeve 35 has been created, which can be inserted, for example, through corresponding holes in a rubber seal or pulled out of the rubber seal without fear of the rubber seal being 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. 20, 22, 10).
  • the sleeve housing 63 fits into the pin trough 13 of the pin housing 12 and results in the connector (Fig. 11).
  • 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.
  • Transverse walls 70 form with the side walls 64, 65 and the longitudinal chamber wall 69 chambers 71 for, for example, circular receptacles 35.
  • the height of one Chamber 71 corresponds approximately to the length of a circular plug-in sleeve, the contact area 40 being supported in a cylindrical chamber area 72, so that the spring arms 47, 48 find free space 73 for the springs to the outside.
  • U-shaped recesses 28a In the area above the chamber area 72 - as with the pin housing l2 - 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. 10).
  • 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. 13 shows this locking position.
  • the housings 12 and 63 according to the invention can of course also be used for other plug contacts which have a projecting element which has the same effect as the bead.
