Definitions

  • the invention relates to a connection terminal for electrical conductors with a terminal housing made of insulating material and with a contact insert having a plurality of juxtaposed in a row terminal points, in which the stripped ends of the electrical conductors from the same side of the terminal housing are inserted parallel to each other.
  • the contact insert such terminals usually consists of a piece of spring steel plate and a common terminal points busbar, which is made of a highly electrically conductive material. From the piece of spring steel sheet a plurality of leaf springs in the form of leaf spring tongues are cut free (or punched) according to the number of clamping points such that their tongue roots are connected to the upper edge region of the spring steel sheet. The free ends of the leaf spring tongues extend in the direction of the lower edge of the spring steel sheet and are each directed against the busbar. They form with the busbar each a terminal point for the electrical and mechanical terminals of an inserted into the connection terminal electrical conductor.
  • connection terminals has been known since 1973 ( DE 23 17 040 C3 ). It has in its basic structure a busbar in the form of a massive (thick), rigid in itself Contact plate made of a highly electrically conductive copper material.
  • the contact plate is the supporting element of the contact insert.
  • the spring steel plate is attached with the cut-leaf spring tongues.
  • a window recess is incorporated for each nip. The electrical conductor to be clamped is first inserted through the window recess, and then the inserted conductor end is clamped by means of the free end of the respectively associated leaf spring tongue against the lower edge or against the lower edge region of the contact plate.
  • DE 25 14 791 A1 discloses a screwless terminal in which a opposite to the Leitereinsteckraum facing contact part, which forms a busbar, at the free ends of a plurality of juxtaposed, separated by recesses Reinlagerplatten has.
  • a recess is arranged, so that these rear bearing plates of the contact part engage through the recess of the spring member, while the clamping fingers come to lie regionally in the recesses of the contact part.
  • the area of the clamping edge carrying the clamping edge Clamping finger is arranged on the fastening point of contact part and spring part remote from the contact part.
  • DE 198 30 484 C1 discloses a clamping connection with a U-shaped bent leaf spring, in which a Anachlusslasche is inserted.
  • the terminal lug is located between two in leaf insertion direction facing leaf spring legs.
  • DE 196 08 356 A1 discloses an electrical terminal with leaf spring terminals for electrical conductors which are formed in loop form with a back opening for the insertion of the electrical conductors and have a loop end which forms the socket part for receiving a solder pin.
  • the loop end with the female part is extended to behind the head ends of the plugged electrical conductors.
  • the present invention is based on the terminal type according to the aforementioned DE 203 03 537 U1 out.
  • the stripping conductors are first inserted through one of the window recesses, which are created by the cutout of the leaf spring tongues in the spring steel sheet.
  • the electrical conductors are then electrically and mechanically clamped in the terminal points, which are formed between the free ends of the leaf spring tongue and the respective strip or bar-shaped busbar.
  • the object of the invention is to provide a connection terminal with reduced overall height, in which a flat and in its wall thickness preferably thin busbar by means of the lower edge region of the spring steel sheet is kept long-fixed, without additional fastening aids (such as, for example, spot welding , Rivets or caulking).
  • connection terminal for the purpose of fixing the location of the busbar, the lower edge region of the spring steel sheet is bent back with a portion of the window recesses there ending against the Porterereinsteckraum, whereby an open against the Porterereinsteck512 and metal-mounted on its other side V-shaped receiving space is formed.
  • V-shaped receiving space is the flat in cross-section and in their Wall thickness thin busbar used, the lengths of the leaf spring tongues are dimensioned so that their tongue ends in unoccupied, closed terminal point engage through the window recesses of the spring steel sheet and rest against the underside of the busbar and fix them.
  • This method of fixing the position of a flat, strip-shaped busbar (or, if desired, a rod-shaped busbar) on or in the lower edge region of the spring steel sheet has considerable advantages in the production of the new terminal by automatic production machine.
  • the prefixed contact insert can also be used in its entirety automatically by automatic production machine in an insulating material.
  • the main extension direction of the window recesses in the spring steel sheet intersect the axes of the clamped electrical conductors at a maximum flat angle of attack, which is achieved by keeping both the upper edge region of the spring steel sheet with the tongue roots of the leaf spring tongues and the lower edge region of the spring steel sheet with the position-fixed Busbar are each positioned closely adjacent to the stripping ends of the clamped electrical conductors.
  • connection terminal is based on a different way. It combines a maximum flat angle of attack with a short leaf spring length, achieving a significant reduction in height, without (or as will be described in more detail below) adversely affecting ladder clamping forces and / or ladder pull-out forces.
  • connection clamp for example a connection socket clamp
  • the tongue ends of the leaf spring tongues are angled in the manner against the clamped electrical conductor, that the measured in the clamping edge of the tongue ends against the electrical conductor wedge angle ⁇ 10 °.
  • Double-row connection terminals are usually only the mirror-symmetrical duplication of a single-row terminal.
  • Such a bus bar has a flat (bottomless) underside, which may be positioned in the V-shaped receiving space such that it is inclined against the Porterereinsteckides such that the underside of the busbar for the inserted into the nip electrical conductor serves as an inlet slope.
  • FIG. 1 shows in cross-section the terminal housing 10 with a superior in autismeinsteckraum housing cover 11 having the Porterereinsteckö réelleen 12, 13 and 14 for the rectified and parallel insertion of a total of three electrical conductors 15 (see Fig. 3 ).
  • FIGS. 4, 5 and 6 show the contact insert, which is installed in the terminal housing 10.
  • the contact insert consists of a piece of spring steel sheet 16 (see Fig. 6 ) and from a busbar 17 (see Fig. 5 ), which is made of a highly electrically conductive copper material.
  • the illustrated 3-conductor connection terminal has three terminal points.
  • the nips are each formed between the free ends 20 of the leaf spring tongues 21 and the bus bar 17. This best shows the in Fig. 4 shown side view of the fully assembled contact insert.
  • the leaf spring tongues 21 are cut from the spring steel sheet 16 in the manner (see Fig. 6 ) that their tongue roots 22 are firmly connected to the so-called upper edge portion 23 of the spring steel sheet.
  • the free ends of the leaf spring tongues 21 extend in the direction of the lower edge region 24 of the spring steel sheet 16.
  • the lower edge region 24 of the spring steel sheet is bent back with the section 25 of the window recesses there ending against the Porterereinsteckraum, whereby means of the spring steel sheet against the Porterereinsteck512 open and on its other sides largely metal-shaped V-shaped receiving space 26 is formed.
  • busbar 17 used in the V-shaped receiving space 26 in the in Fig. 5 shown busbar 17 used.
  • the busbar 17 is formed in cross section as a flat, strip-shaped busbar. It extends over all free terminal points, their wall thickness is relatively thin and only slightly stronger than the material thickness of the spring steel sheet (see. Fig. 4 ).
  • the busbar has three laterally projecting busbar heads 27, which extend into the V-shaped receiving space 26 in the bent back in Leitereinsteckides sections 25 of the window recesses upon insertion of the busbar.
  • the flat and relatively thin bus bar 17 is positioned in the V-shaped receiving space 26 so that its smooth underside serves as an inlet slope for the electrical conductor 15 to be inserted.
  • a comparison of Fig. 4 With Fig. 2 shows this more exactly.
  • the last end piece 20 of the leaf spring tongues 21 is slightly angled against the clamped conductors 15, so that the measured in the clamping edge of the tongue ends against the electrical conductor 15 wedge angle ⁇ 10 °. This wedge angle design increases the ladder pull-out forces.
  • the conductor clamping forces, the leaf spring tongues 21 as a result of the manufacturing technology pre-deformed root bow 28 and the pre-deformed reverse bend 29 on the clamped electrical conductor 15th exercise, are sufficiently large. They are supported by the separating cuts 30 in the spring steel sheet (see Fig. 6 ), which on both sides adjacent to each leaf spring tongue 21 separate support webs 31 form, which independently rebound on rebound of the leaf spring tongue 21. In order to reinforce this desired co-springing of the support webs 31, the support webs 31 each have pre-formed suspension bends 32 (see FIG 4 and FIG. 6 ).
  • Fig. 2 and Fig. 1 show that both the upper edge portion 23 of the spring steel sheet 16 with the tongue roots in 22 of the leaf spring tongues 21 and the lower edge portion 24 of the spring steel sheet 16 with the position-held bus bar 17 are respectively positioned closely adjacent to the stripped ends 18 of the clamped electrical conductors 15.
  • the main direction of extension of the window recesses caused by the free cutting (or free punching) of the leaf spring tongues 21 in the spring steel sheet 16 intersect the axes of the clamped electrical conductors 15 at a maximum flat angle of attack.
  • the overall height of the contact insert (and thus the overall height of the connection terminal is significantly reduced overall.
  • the height reduction of the clamp is from the Figures 1 and 2 good to see. Neither the upper edge region 23 of the spring steel sheet 18 (including the leaf spring tongues 21 running away therefrom) nor the lower edge region 24 of the spring steel sheet 16 (including the busbar 17 held in position) protrude beyond the outer contour formed by the axially parallel extension of the outer diameter of the insulation jacket 19 is predetermined, the to belongs to the maximum conductor cross-section, which can be clamped in the illustrated connection terminal.
