Definitions

  • the invention is based on a multi-pin connector for printed circuits according to the preamble of claim 1.
  • Plug connections are generally used for repeated connection or disconnection of electrical conduction paths, with the primary task of reliably and reproducibly making electrical and electrical contact or disconnection over a longer period of time under predetermined mechanical, electrical and climatic environmental conditions. In order to be able to optimally meet these environmental conditions, there is a wealth of embodiments of plug connections adapted to the respective intended use.
  • the connector described below is one of the connections that e.g. find use in radio or television sets or in computers and peripheral devices. Even in this narrow circle of plug connections there are a very large number of embodiments which e.g.
  • the connector according to the following description is called a so-called Small socket designated.
  • Small socket There are those of this type which have a wire connection and those which are suitable for use in a printed circuit. This different use naturally also requires different embodiments.
  • connectors for printed circuits In one type, it is installed vertically in the printed circuit, so that the direction of insertion of the plug is vertical. In the other type, the direction of insertion is parallel to the printed circuit.
  • a socket for printed circuits is already known, in which contact springs are used in an insulating body in its recesses, the solder connections of which are led out from the bottom of the insulating body.
  • the insulating body consists of a rectangular front plate, which is followed by an essentially cylindrical molded part on the back.
  • the insulating body also has a plug ring space for receiving a sleeve of a plug.
  • plugs whose sleeves are made of plastic or a metal. If the sleeve is made of plastic, one of the pins or poles must lead to ground. However, if the sleeve is made of a metal, there is usually an earth spring in the socket, which allows point contact.
  • the grounding spring here consists of an approximately U-shaped sheet metal part with a base part, the cut soldering tabs can be inserted into the printed circuit.
  • the sheet metal part is supported in the insulating body with the base part.
  • the actual contact tongue extends from the base part approximately in the middle upwards and backwards. In the installed state, this contact tongue projects into the plug ring space, so that when a plug is inserted with a metal sleeve, there is a point-like or linear contact.
  • the socket in turn consists of an insulating body, in which contact springs and an earth spring projecting into the plug ring space are present.
  • the plug ring space has a cylindrical extension into which a piece of pipe serving as a shielding sleeve is inserted. The pipe piece is punched out of a sheet and bent into a pipe. For the actual contacting with the connector sleeve, a cut out of the sheet metal and used inside curved contact tongue that protrudes into the connector ring space. Here, too, there is only point contact with the plug sleeve.
  • This piece of pipe also has a soldering tab that protrudes from the bottom of the insulating body.
  • the object of the present invention is to find, for a multipole plug connection for printed circuits of the type mentioned at the outset, an easily interchangeable earthing spring as required either with the earthing spring with single-point or line contacting, which permits reliable all-round contacting of the plug sleeve of the plug.
  • the all-round contacting of the plug sleeve achieves better shielding and earthing, and above all, it is cheaper at higher frequencies.
  • possible contact difficulties caused by impurities with different transition resistances which can never be completely ruled out with single-point or line contacting, are almost completely eliminated by the multiple contacting.
  • the all-round contact is made by resilient contact tongues, connector sleeves with the usual fluctuations in the manufacturing tolerances with regard to the diameter can also be used without the all-round contacting being adversely affected in any way.
  • a higher mechanical insertion or extraction force is achieved, which ultimately serves to ensure the safety of the plug connection, since this force is applied by several springs which are distributed uniformly both on the circumference and in the middle by the contact springs of the socket.
  • a single-point earthing spring will always load the connector sleeve on one side, so that the connector sleeve will be inclined differently in the socket, of course depending on the space available and the arrangement and number of contact springs.
  • the plug connection shown in FIG. 1 consists of a plug 2 and a socket 1.
  • the plug 2 is a 4-pin plug, the plug pins of which are designated by 8 in FIG.
  • a plug could also be used which has a different number of plug pins, for example three, five, six, seven or eight.
  • the connector pins not visible in FIG. 1 — are provided over part of their length with a cylindrical recess with which they are held in a hard paper plate or with which — as shown in FIG. 1 — they are injected into a holding body 21 made of plastic.
  • the holding body has an opening approximately in the middle through which a rivet eyelet 22 is guided and fastened by crimping.
  • This rivet eyelet is used to hold a sheet metal bracket 23 which engages in a recess of the holding body with an embossing which is not visible in FIG. This ensures that the sheet metal angle is protected against twisting.
  • the sheet metal bracket 23 is U-shaped by two angled tabs which serve to hold or relieve strain on a cable 25 guided through the rubber grommet 24. The cable is clamped by bending the two tabs inwards towards one another, and the cable shield can also be soldered on.
  • the rubber grommet is provided with a groove which is not visible in FIG. 1 and which engages in a collar-like bead of a sleeve-shaped outer conductor 3.
  • This outer conductor is manufactured, for example, in die-cast zinc and then copper-plated and nickel-plated, so that it is a good conductor of electricity.
  • a leg of the sheet metal bracket running parallel to the inner wall of the outer conductor is provided with a thread for a screw 26 which passes through a corresponding lateral hole in the outer conductor is guided. This creates the electrical connection between the outer conductor and the cable shield.
  • the counterpart of the plug 2 is formed by the socket 1 made of plastic.
  • This consists of an approximately rectangular housing end face 4 and a housing part 5 integrally molded thereon.
  • a middle part 6 surrounded by a plug ring space is integrally connected to the housing part, in the spring chambers of which the contact springs 7 in the form of forked springs for contacting are formed as flat stamped parts are inserted with the connector pins 8.
  • the contact springs 7 are held by a support plate 27 made of hard paper, which is attached to the back of the housing part by thermoforming two retaining pins 28 on the housing part, or by a support plate made of plastic, which is connected by a connection, e.g. Gluing, snapping, thermoforming of holding pins and the like. Is attached to the housing part.
  • the socket has a recess 20 on the front on the underside, which extends through the housing end face 4 into the housing part 5.
  • This recess receives the solder connection 18 of a sheet metal part 10.
  • Two soldering tabs 19 connect to the solder connection 18 and protrude from the bottom of the housing part.
  • the sheet metal part 10 itself consists of a metal which is preferably electrically good conductive.
  • the surface of the sheet metal part can e.g. silvered, tinned, nickel-plated or the like.
  • the sheet metal part is approximately rectangular and its size corresponds approximately to the front of the housing end face 4.
  • the push-through opening 11 In the middle of the sheet metal part is the push-through opening 11 through which the plug can be inserted into the socket.
  • the plug can be inserted into the socket.
  • the sheet metal part 10 has side edge sections 15 bent at right angles on three sides, the width of which corresponds approximately to the thickness of the housing end face. These margin sections have flanging holding tongues 16 distributed over their length at several points.
  • the sheet metal part is now pushed into the socket, the recess 20 receiving the solder connection 18 with the solder lugs. Then the retaining tongues 16 are bent, with which the sheet metal part is then fastened to the socket.
  • the sheet metal part represents an additional part to be attached. If a different ground connection is required, the usual earthing spring with the same solder connection and the same soldering lugs can be used instead of the sheet metal part.
  • the socket itself is completely identical in both cases.
  • a plurality of contact tongues 12 are arranged on the circumference, which are bent backwards and protrude into the plug ring space 9.
  • the push-through opening has a funnel-shaped edge part 14 which likewise projects into the plug ring space.
  • the inside width of the edge part is larger than the largest diameter of the plug outer conductor. Since the contact tongues resiliently rest on the outer conductor with pretension, plugs from different manufacturers can be used, which are also subject to the usual manufacturing tolerances.
  • the contact tongues extend from the edge part to the rear, and for better spring properties they have a decreasing width towards their free end.
  • each free end of a contact tongue is provided with an inward bend 13. With this deflection, the spring tongue rests on the connector outer conductor. Since the plug outer conductor is round, the contact tongues in the region of their foot at the edge part have a curvature which is adapted to the radius of curvature of the plug to be received.
