Definitions

  • the invention relates to a lockable electrical sheet metal socket formed from sheet metal with a substantially channel-shaped receiving part, which has a bottom and edged side walls, free edge portions of the side walls being arched inward above the floor for receiving a complementary flat tab between two raised protrusions and the convex edge sections, with a tongue which is formed in one piece with the bottom and which extends rearward from the front end of the receiving part within the latter, the upper surface of which is provided within the receiving part with a tab which projects obliquely backwards from the tongue to the convex edge sections of the side walls , which is designed such that it engages in a corresponding recess or opening in the complementary flat connector when this is inserted into the flat connector, whereby the flat connector against being pulled out of the Flat receptacle can be secured, and with a release member at the free end of the tongue, by the actuation of which the tongue is resiliently bendable towards the bottom, so that the tab provided on the tongue can be released from the flat plug inserted into the flat
  • the invention is based on a flat receptacle and an electrical connector, as are known from FR-A-2 504 741.
  • the tongues are extended beyond the plug-in or receiving area and then angled upward to form a releasing member, and each penetrate a recess in the convex edge portions which protrude from the floor.
  • the invention has for its object to provide a lockable flat receptacle of the type mentioned, in which despite the attachment of a release member on the bent tongue, the length of the tongue is very short and consequently ur a narrow sheet metal strip is required to manufacture the flat receptacle and further has a low overall height.
  • a corresponding connector is also to be created.
  • This training has the advantage that the point of attack on the release link - over the insertion length, d. H. seen over the length of the receiving part - is between the locking tab and the rear end of the flat receptacle, despite the arrangement of the bent tongue. Due to this small distance of the point of application from the locking tab, only a slight deflection of the tongue end is required in order to pull the locking tab out of the opening or recess of the tab connector. The release link no longer protrudes above the floor or over the edge sections, so that the overall height of the flat receptacle is reduced. A central receptacle of the tab connector between the floor and edge sections is also possible.
  • each indentation comprises at least one shape extending in the direction of the free edge sections.
  • the free edge sections can initially be curved inwards, towards the floor, but then end with a short section pointing away from the floor.
  • the arch-shaped contact surfaces of the edge sections or the stampings obtained are then also refined after punching and bending. B. covered with tin.
  • the convex edge sections can have fingers behind the free end of the tongue, which extend downward and end below the free end. The fingers then serve as a plug-in limitation for the flat plug to be inserted.
  • the flat receptacle is characterized in that, in a symmetrical arrangement, two tabs of the tongue are formed as angles, which consist of an approximately horizontal part which extends in the plane of the tongue and an approximately vertical part which extends towards the floor exist, and that each approximately vertical part penetrates a slot.
  • An electrical connector with a flat receptacle has a Insulating housing in which the, flat socket is axially movable between two stops and in which at least one lower wall part is provided with an obliquely upward surface, which with an axial displacement of the flat socket relative to the housing with at least one tab of the
  • Tongue comes into sliding engagement, whereby the resilient bending of the tongue required for releasing is effected, and is characterized in that the inclined surfaces on the lower part of the wall are arranged within the indentations of the flat plug socket, as a result of which an extremely low overall height of the corresponding housing can be achieved.
  • a central arrangement of the plug-in area within the housing is possible, so that the flat plug socket can also be inserted into the housing offset by 180, ie. H. can be mounted on an envelope.
  • the flat receptacle is formed from tin-plated metal sheet and is provided with a connecting claw 2 for connection to a conductor, not shown. Such a connecting claw can be used for connection by means of crimping, welding, soldering and the like.
  • the front end of the flat receptacle 1 is designed as a receiving part 3 for a flat plug.
  • the flat receptacle 1 is constructed symmetrically so that the same parts are provided with the same reference numbers.
  • the likewise symmetrical receiving part 3 comprises a central bottom 4, to which stepped side walls 5 adjoin.
  • the side walls 5 consist of a first section 5a initially projecting at right angles from the bottom 4, a second section 5b which adjoins approximately horizontally and a third section 5c which in turn adjoins at right angles and which, finally bent, points back to the bottom 4 as a free edge section 6 .
  • the shape of the side walls 5 results in two indentations 5d running in the plugging direction of the flat plug socket. By bending away the ends 6a of the edge sections 6, two rounded edges 6b, pointing towards the bottom q, result in the front receiving area 3, cf.
  • Figure 2 By bending away the ends 6a of the edge sections 6, two rounded edges 6b, pointing towards the bottom q, result in the front receiving area 3, cf. Figure 2.
  • the edge portions 6 in the form of fingers 8 as a stop for the flat plug to be accommodated are bent further downward toward the bottom 4.
  • the edge portions 6 in the form of fingers 8 are bent further downward toward the bottom 4.
  • upwardly rounded shapes 9 are pressed out in the front region.
  • the indentations 5d are provided with slots 10, the width of which extends into the first and third sections 5a and 5c.
  • a tongue 11 is formed on the base 4 at the front end, which is slightly narrower than the distance between the two sections 5a.
  • the tongue 11 is bent upwards and backwards in the direction of the floor 4 by 180 ° and extends obliquely to the rear.
  • the tongue 11 ends within the receiving part 3 and lies with its rear end of the upper surface 12 against the rounded edges 6b of the edge sections 6, cf.
  • Figure. 1 In the central region of the tongue 11, a barb in the form of a tab 13 is punched out of the plane of the tongue 11.
  • the tab 13 forms a locking edge 14 for the flat plug to be inserted, cf.
  • Two tabs 16 formed laterally on the rear, free end 15 of the tongue 11 serve as release members.
  • Each tab 16 is shaped as an angle, with a horizontal part 17, which runs laterally next to the free end 15 of the tongue 11, and with one vertical part 18, which adjoins the horizontal part 17 downwards.
  • Each tab 16 penetrates the slots 10 with play with the vertical part 18, emerges from the bottom of the slots 5 and extends forward with a rounding 19, i. H. in the direction of the front end of the receiving part 3, see FIG. 3.
  • the vertical part 18 has a sloping surface 20 pointing towards the tongue 11, which slopes towards the front end of the receiving part 3.
  • a barb 21 punched out from the central region of the base 4 serves to latch the flat plug socket 1 in a housing.
  • the flat receptacle 1 is in a housing 22 made of insulating plastic, for. B. made of polyamide, to form an electrical connector 23.
  • the housing 22 is also constructed symmetrically and has one channel-shaped passage 24 with an upper wall 25, a lower wall 26 and side walls 27 and 28.
  • two grooves 33 are made in a symmetrical arrangement, which emerge in the rear area of the housing 22 which is broken off in FIGS. 3 and 4.
  • the surface 35 ends with an edge 37, which is adjoined by a stop surface 38 running vertically upwards.
  • the stop surface 38 opens into the bottom surfaces 39 of the passage 24, cf. Figures 3 to 5.
  • the housing bevels 40 are molded for the insertion of a tab described below.
  • the flat receptacle 1 is pushed into the housing 22 from the rear, see FIG. 3, until the barb 21 snaps into the groove 29 and is held in the housing 22 by the shoulder 30.
  • the second latching takes place by engaging the tab 31 which bends away during insertion behind the abutment surface 32.
  • the tabs 16 are located partly inside, partly below the slots 10 of the flat socket 1.
  • the vertical parts 18 hit the abutment surfaces during a further displacement 38 on, so that the flat receptacle 1 is secured with a predetermined play against displacement in both axial directions, cf. Figure 3.
  • FIG. 4 to 6 The connection with a flat plug is shown in Figures 4 to 6.
  • a flat plug 41 made of sheet metal and having an opening 42 is pushed between the tongue 11 and the edges 6b of the edge sections 6 until the tab 13 enters the opening 42.
  • the tongue 11 bends towards the bottom 4, so that the vertical parts 18 of the tabs 16 are bent further downward.
  • the edge sections 6 are somewhat bent, and the tab 41 is clamped between the edge sections 6 and the features 9, cf. in particular Figure 5.
  • the latch 13 prevents by its latching in the opening 42 that simply pulling on the flat connector 41 or on the flat connector 1, a release of the electrical connection is possible.
  • An excessive insertion of a tab 41 is opposed by the fingers 8, which extend further downward behind the free end 15 of the tongue 11 than the rounded edges 6b and thus form an axial stop 8a for the tab 41.
  • a loosening of the connection is possible by a further bending of the tongue 11 in the direction of the lower wall 26 of the housing 22, because the tab 13 then comes out of the opening 42 again.
  • the further deflection of the tongue 11 is possible by a further bending of the tongue 11 in the direction of the lower wall 26 of the housing 22, because the tab 13 then comes out of the opening 42 again.
  • the invention is particularly applicable to electrical devices, apparatus, devices and machines, in particular when they are exposed to vibrations, and also in the electrical wiring of automobiles. It serves for the permanent but easily detachable electrical connection of electrical lines with other electrical lines or of other electrical components with electrical lines.
