Definitions

  • the invention relates to a connector for a high frequency of insertion according to the preamble of claim 1.
  • Such a connector is previously known from DE-A-3 027 047 / US-A-4 410 225.
  • the connector insert is designed as a printed circuit board on which the conductor tracks are printed.
  • two plug tongues are provided, each with printed conductor tracks on both sides.
  • the plug insert is inserted with its two plug tongues into the insert part which is accommodated in the housing, web-like extensions of the insert part engaging between the two plug tongues, which are provided with locking knobs at the free ends.
  • the connector tongues engage between the isolating contacts of the terminal block and the locking knobs in the plastic body of the terminal block.
  • a connector of a connecting cord for distributors of telephone exchange technology is also known, which connector is formed from two connector tongues, a connecting cord and a handle part.
  • Each connector tongue consists of two metal strips with opposing teeth, which are bent at a certain angle to each other.
  • the space occupied by the sheet metal strip is sprayed with insulating material, preferably plastic, so that the two sheet metal strips form electrically separate contact paths of the plug tongues.
  • insulating material preferably plastic
  • a connector as a connector for telecommunications, which is formed from a plastic body with a thickening provided with slot-shaped openings serving as a connector handle and from sheet metal strips as conductor tracks which are inserted into the slot-shaped openings are.
  • the metal sheet strips are bent semicircularly at the end of the connector tongues and inserted into grooves formed at the end of the connector tongues. Furthermore, the metal sheet strips are slightly pre-bent outwards in the region of the thickening transversely to the longitudinal direction, so as to be pressed firmly against them in the region of the plug tongues.
  • barbs are formed on the metal sheet strips, which engage behind notches provided in the area of the thickening.
  • this known plug does not require a separate housing for receiving a plug insert, it is extremely complex to manufacture due to the complicated design of the conductor tracks from metal strip strips which are to be machined repeatedly and are difficult to assemble.
  • the invention is therefore based on the object to improve a connector of the generic type in such a way that the conductor tracks and the plug insert are simple and inexpensive to manufacture, and that wear or destruction of the conductor tracks is avoided despite the high frequency of plugging.
  • the conductor tracks of the plug insert consist of stamped parts which are simple and inexpensive to manufacture.
  • the carrier and the insert are also formed in one piece from plastic injection molding material, the conductor tracks being encapsulated with the plastic in the area of the insert and only partially embedded in the plastic in the area of the plug tongue and the connection end.
  • a particularly advantageous embodiment of the stamped parts results from sub-claim 2.
  • the conductor tracks formed from stamped parts are held particularly securely, in particular on the thin and narrow plug tongues. Due to the features of subclaim 3, the free ends of the plug tongues are formed in full width from the stamped parts forming the conductor tracks, premature wear of the plug tongues being avoided with a high frequency of plugging of the plug, on the one hand, and reliable contacting with the contacts of a terminal strip being ensured on the other hand.
  • Figures 1 and 5 show a two-pole plug insert 1, which is formed from a carrier 2 and an insert part 3 made of plastic, the carrier 2 having on both sides conductor tracks 4, which are formed from stamped parts, made of thin conductive metal.
  • the two-pole plug insert 1 is made with its support 2 and the insert 3 in one piece from plastic by injection molding, the conductor tracks 4 formed from stamped parts being extrusion-coated with the plastic in the area of the insert 3 and partially in the plastic in the area of the tongue 5 and the connection end 6 are embedded.
  • the insert 3 is thus located approximately in the middle between the tongue 5 and the connection end 6 of the plug insert 1.
  • each conductor track 4 formed from a stamped part is provided on the longitudinal side edges with angled legs 7, which extend into the plastic carrier 2, so that each conductor track 4 with the legs 7 is buried in the plastic carrier 2.
  • the surface of the conductor track 4 protrudes slightly beyond the surface of the plastic carrier 2.
  • the conductor tracks 4 formed from stamped parts are widened to the entire width of the connector tongue 5 at the end of the connector tongue 5, so that wide insert blades 8 are formed.
  • FIGS. 5 and 8 also show that the plastic carrier 2 of the connector tongue 5 is provided on one side with a locking knob 9 which is arched outward in the form of an arc from the plastic material of the connector tongue 5 and which is used for latching behind catches 33 formed in the terminal strips 34, as will be described later.
  • the approximately in the middle between the tongue and the connecting end 6 of the plug insert 1 and compared to the plastic carrier 2 in the area of the tongue 5 and the connecting end 6 thicker insert 3 has in the illustration according to Figures 1 and 5 on the top and left side of a groove 10 and on the right-hand side a projecting web 11, the internal dimensions of the groove 10 being matched to one another so that the web 11 fits into the groove 10 of a further plug insert 1, 21, as will be described later.
  • a locking lug 12 and on your web 11 a locking groove 13 are provided, which serve for locking when the groove 10 and the web 11 engage.
  • connection end 6 of the carrier 2 made of plastic is provided for each conductor track 4 with a bushing 14, which is extended on the opposite side of the carrier 2 by means of a tubular sleeve 15 which is integrally formed with the carrier 2 made of plastic.
  • the bushing 14 with the sleeve 15 is used to lay a connecting cable (not shown) to the conductor tracks 4, which have an arcuate cutout 16 in the area of the sleeve 15.
  • the conductor tracks 4 formed from stamped parts comprise connecting tabs 17 with which the conductor tracks 4 for carrying out the injection molding process are accommodated in a frame (not shown) for receiving in the plastic injection mold and which are cut off after the molding.
  • FIGS. 2, 3 and 6, 7 show a four-pole plug insert 21, which essentially corresponds to the 2-pole plug insert 1 according to FIGS. 1, 5 and 8.
  • the 4-pin plug insert 21 has a plastic carrier 22, an insert part 23 and four conductor tracks 4, which are formed on the opposite sides of two plug tongues 5, 5 '. Both plug tongues 5, 5 '- each have a locking knob 9, 9' - on their opposite outer sides.
  • the connecting end 26 of the 4-pin plug insert 21 is provided with four bushings 14, each provided with a sleeve 15, which on each of the both sides of the connecting end 26 are formed.
  • the insert 23 is provided on the left side with a groove 10 with a detent 12 located therein.
  • FIG. 4 shows how two plug inserts shown here only in a simplified representation according to FIGS. 1 and 2, namely the 2-pin plug insert 1 according to FIG. 1 and the 4-pin plug insert 21 according to FIG. 2 are lined up, the Web 11 of the 2-pin plug insert 1 engages in the groove 10 of the 4-pin 20 plug insert 21. In a manner not shown here, locking web 12 and locking groove 13 also engage in one another. A 6-pin plug insert 31 is thus formed.
  • FIG. 9 shows the 6-pin plug insert 31 according to FIG. 4 in a housing 32 which, according to DE-A-3 022 047 / US-A-4 410 225, is formed from two identical housing shells which form the 6-pin plug insert 31, the ribs 24 of the insert parts 3, 23 engaging in a manner not shown in the grooves formed in both housing shells, not shown.
  • FIG. 10 shows a 4-pin plug from the double-shell housing 32 with a 4-pin plug insert 21 according to FIG. 2 inserted therein
  • FIGS. 11 and 12 show a 4-pin plug inserted into a terminal block 34 with a 4-pin plug insert 21, the latching knobs 9, 9 'of which engage behind detents 33 which are formed in the plastic body of the terminal block 34.
  • the terminal block 34 is described in its basic design in DE-A-2 804 478 / US-A-4 283 103.
