Definitions

  • the invention relates to a mother connector part of an electrical connector, having at least the following:
  • At least one contact socket with on the one hand a socket part for receiving a plug pin and on the other hand a connecting part to which an electrical conductor can be fastened, and
  • At least one contact sleeve with a substantially cylindrical spring holder and a plurality of contact springs which encompass at least one end face of the spring holder.
  • the known contact sockets for mother plug parts are made in several parts, ie the contact socket is composed of several parts.
  • the socket parts of the known contact socket consist of at least two turned parts (that is, parts produced by turning) which have to be connected to one another.
  • the manufacture and assembly of such contact sockets is complex and consumes material.
  • the object of the invention is to design a mother connector part for an electrical connector in such a way that the manufacturing and assembly work is as low as possible and that constant contact forces and the largest possible contact area for the passage of current are ensured even after frequent contacting.
  • the contact socket is formed from a one-piece piece of a contact plate and that the contact sleeve is mounted in the socket part of the contact socket by means of at least one tongue and groove arrangement.
  • the design of the mother plug part according to the invention not only enables essentially constant plug-in and pulling forces with reliable contact between the plug pin and sleeve, but also low material consumption and manufacturability of the mother plug part with automatic machines, the mother plug part being able to be produced automatically from a one-piece blank of a contact plate is.
  • the electrical contact between the contact sleeve and the body of the contact socket is also improved.
  • the tongue and groove arrangement as the groove has at least one bulge in the socket part.
  • a further preferred embodiment of the invention provides that the tongue and groove arrangement as a spring has a section of at least one contact spring.
  • contact springs are designed as wires.
  • electrical conductor can be fastened to the connecting part of the contact socket by crimping or crimping.
  • the socket part of the contact socket has a plurality of radial bulges in which end regions of the contact springs are received.
  • Another preferred embodiment of the invention provides that the contact springs engage the inner wall of the socket part of the contact socket under radial tension.
  • a further preferred embodiment of the invention provides that the contact springs are formed as wires which surround the cylindrical contact spring holder with a bending point at least at one free end face, an end region of each contact spring being in engagement with the inner wall of the socket part.
  • a further preferred embodiment of the invention provides that the section of the contact socket forming the socket part has complementary recesses and projections which are each formed on adjacent edges of the contact plate forming the socket part in order to form a closed cylindrical shape.
  • the free end of the socket part of the contact socket is at least partially bent inwards. With such a radial bending point, the socket part and thus the contact socket are in additional electrical contact with the contact sleeve, and there is also an additional safeguard against undesired pulling out of the contact sleeve from the socket part.
  • the socket part of the contact socket is provided, at least in the region of its two axial ends, with radially directed bulges into which the contact springs engage, the springs being under radial tension.
  • the socket part of the contact socket can also be provided over its entire length with bead-shaped formations, which form the aforementioned bulges for receiving the contact springs after the socket part has rolled.
  • the contact springs can be formed on the one hand by separate wires, but on the other hand also from the material of the substantially zylinderför contact spring holder itself.
  • the contact springs are punched out of the material of the contact spring holder and bent over the axial face of the contact spring holder, so that they with the inner wall of the socket part come into engagement, as is otherwise described here for separate wire springs.
  • the springs punched out of the contact spring holder are integral with the contact spring holder at one end.
  • the socket part In the manufacture of the mother plug part, the socket part can be rolled and, as explained above, by means of interlocking interlocking recesses and projections, the longitudinal edges of the sheet metal forming the socket part, which are adjacent after the rolling, can be linked together. If the contact sleeve has previously been inserted into the rolled socket part, the radial tension of the contact springs can be achieved in a simple manner in this way during the manufacturing process.
  • the above-mentioned projections and recesses on the longitudinal edges of the sheet forming the bushing part are exactly complementary to one another, ie the projections fit exactly into the corresponding recesses, so that when the bushing part is completely rolled up, a closed cylindrical shape is created.
  • the recesses on the longitudinal edges of the sheet metal forming the socket part are preferably behind cut to achieve a positive connection with the projections engaging in the recesses.
  • connection of the longitudinal edges of the sheet that come into mutual contact when the bushing part rolls can also be achieved in that at least one recess and at least one projection are provided on each of the two longitudinal edges in order to achieve a mutual connection of the longitudinal edges.
  • the mother plug part has a section with a reduced diameter, so that a step is formed by different radii, with the aid of which the mother plug part engages in a designated position in the housing.
  • Figure 1 is a side view of a contact socket for a mother connector part
  • FIG. 2 shows a view of a contact socket corresponding to FIG. 1, the so-called socket section being cut;
  • FIG. 3 shows a section through a contact socket according to FIG. 1 in the region of the socket part.
  • the mother plug part according to the exemplary embodiment shown has a contact socket 1 which is designed overall in a rotationally symmetrical manner about its longitudinal axis A.
  • the contact socket 1 consists overall of a one-piece cut of a sheet with good electrical contact properties.
  • the contact socket 1 serves for the electrical connection between a plug pin 15 (see FIG. 2) and an electrical conductor 17.
  • the contact socket 1 contains a contact sleeve 2 (see FIG. 2) which is inserted into a socket part 3 of the contact socket 1.
  • the contact sleeve 2 receives the plug pin 15 and thereby creates a continuous contact from the plug pin 15 to the wall of the contact socket 1.
  • Electrically insulating components which at least partially surround the contact socket 1 and also an outer housing are not shown in the drawing, since the insulating parts and the housing as such does not form the subject of the invention.
  • the contact socket has a connection part 4 at its end located at the top in the figures, which serves to connect the conductor 17.
  • a tongue 18 is formed on the conductor 17, which protrudes into the connecting part 4 (cf. the dashed line of the tongue 18).
  • the contact socket 1 has a constriction 5 with a reduced diameter between the socket part 3 and the connecting part 4. This section with reduced diameter is used to position the contact socket in a housing (not shown).
  • the constriction 5 forms, according to FIGS. 1 and 2, conical steps at both ends, which can be brought into engagement with corresponding conical surfaces in the housing (not shown) in a precisely positioned manner.
  • a contact sleeve 2 is positioned in the socket part 3 of the contact socket 1.
  • the contact sleeve 2 has a cylindrical contact spring holder 6 and contact springs 7.
  • the contact springs 7 are designed as resilient wires.
  • a large number of resilient wires 7 extend through the interior of the contact spring holder 6.
  • the contact springs 7 are bent over and thus form bending points 8.
  • the end regions the contact springs 7 are designated 8 *. These end regions 8 'of the contact springs 7 are in electrical contact with the wall of the socket part 3.
  • the bending points 8 of the contact springs 7 are under radial tension.
  • FIG. 3 shows a section perpendicular to the axis A of the contact socket 1 in the region of an end face of the socket part 3.
  • the socket part 3 is formed with a plurality of bulges 9 into which the end regions 8 ′ of the contact springs 7 engage.
  • the engagement of the end regions 8 'of the contact springs 7 in the bulges 9 on the one hand a large-area electrical contact between the contact springs 7 and the socket part 3 of the contact socket 1 is achieved and, on the other hand, the engagement of the end regions 8' in the bulges 9 ensures a rotation of the Contact sleeve 2 overall in the socket part 3.
  • the anti-rotation device described above by means of the end regions 8 'of the contact springs and the bulges 9 acts in the manner of a tongue and groove connection.
  • the radial tension in the contact springs 7, in particular in their bending points 8, causes a jamming of the contact sleeve 2 in the socket part 3 of the contact socket 1.
  • the bulges 9 can either extend over the entire axial length of the socket part 3 or can be formed only at the axial ends of the socket part 3.
  • the end regions 8 'of the contact springs 7 can be longer than is shown in FIG. 2.
  • contact springs 7 are guided in six corresponding bulges 9 in the socket part 3.
  • a plug pin 15 is inserted in the direction of the arrow into the socket part 3 and into the contact sleeve 2 and thus comes into electrical contact with the contact springs 7.
  • the contact socket 1 and in particular its socket part 3 can be produced by rolling a correspondingly cut piece of sheet metal.
  • the socket part 3 In order to achieve a closed cylindrical shape for the socket part 3 (cf. FIG. 3), it is provided that the longitudinal rims coming into mutual contact after the rolling 10, 11 of the sheet metal piece forming the socket part 3, recesses 13 or projections 14 are formed in the manner shown (FIG. 1).
  • the projections 14 complementary fit into the undercut recesses 13, so that there is an uninterrupted surface of the socket part 3.
  • the socket part 3 can at least partially be slightly bent inwards at its axial end located below in the figures, so that the contact sleeve 2 is secured in the socket part 3.
  • the contact sleeve 2 can also have a contact spring holder 6 which is formed in one piece (integral) with the contact springs 7.
  • the contact springs z. B. bent out of the contact spring holder 6 by partial punching, for. B. in the form of individual sheet metal strips, which are bent around the axial end faces of the contact spring holder according to the contact springs 7 shown in the figures and thus come into axial engagement with the inner wall of the socket part 3, the bending points being under radial tension.
