Definitions

  • the present invention relates to a connection socket with a connection part and a contact part.
  • connection sockets are used, for example, with filter plugs.
  • the contact part is usually designed as a plug-in area, while the connection part is designed as a soldering pin for a printed circuit or as a crimp connection for a line.
  • connection sockets have been made in one piece.
  • conventional connection sockets are gold-plated overall.
  • the connecting part which is designed as a soldering pin, is tinned in order to enable the soldering of lines or conductor tracks of printed circuits. It has now been found that, despite the tinning of the connection part, after a while it can no longer be soldered to lines. On connection sockets already connected to lines, it can be observed that the contact resistance in the solder joints deteriorates increasingly after some time.
  • connection socket create which can ensure both a low contact resistance on the connection part as well as on the contact part, is the object of the present invention.
  • connection part and the contact part are designed as separate components which are joined together to form the connection socket. If necessary, this can be done by a press fit.
  • connection socket Due to the separate design of the contact part and the connecting part of the connection socket, these parts can have different base or surface materials. In contrast to one-piece connection sockets according to the prior art, the connection socket according to the invention only needs to be subjected to a simple surface treatment in the region of its connection part. Another advantage of the two-part design of the connection socket is that different socket types can be produced with relatively little effort. For example, the same contact part can either be provided with a connecting part designed as a solder pin or with a connecting part designed as a crimp or crimp connection.
  • connection part consists of tin or a tin alloy at least in the area of its surface, while the contact part consists of gold or a gold alloy at least in the area of its surface.
  • the connecting part is advantageously formed at one end as an elongated tubular socket receptacle.
  • the contact part forming the actual socket can be inserted into this socket receptacle.
  • the contact part is designed as an elongated, tubular plug-in socket, the outer diameter of the plug-in socket being adapted to the inner diameter of the socket receptacle of the connecting part as a press fit.
  • the plug-in socket has approximately diametrically opposed longitudinal slots which extend from the open socket end to approximately a socket foot piece which closes the plug-in socket.
  • the parts of the socket delimited by the longitudinal slots can yield resiliently and thus ensure good contact resistance between the plug and socket.
  • a circumferential, annular bead is arranged on the outer circumference of the plug-in socket at a distance from the socket foot piece and from the open socket end in the region of the longitudinal slots, the outer diameter of which is larger than the inner diameter of the socket receptacle of the connecting part.
  • This circular ring-shaped bead has a double function.
  • the tongues of the plug-in socket remaining between the longitudinal slots are pressed resiliently inward so that they exert a force radially outward on the socket receptacle via the annular bead. This further improves the fit of the plug-in socket in the socket receptacle.
  • connection socket the inward pressing of the tongues of the plug-in socket remaining between the longitudinal slots causes a certain pretension, so that when a plug is inserted into the socket, a resilient yielding of the tongues of the plug-in socket remaining between the longitudinal slots is achieved.
  • connection part is not designed as a solder pin or crimp connection.
  • connection part and the contact part are coated with different surface materials.
  • connection socket Claim 7 The further configuration according to is particularly advantageous for the assembly of the connection socket Claim 7, according to which an inclined insertion slope is arranged on the circumferential bead from the direction of the socket foot piece.
  • the socket foot piece is cylindrical and is provided with splines on its cylinder outside, the diameter of the enveloping spline being larger than the inside diameter of the beech receptacle of the connecting part in the area of the socket foot piece.
  • the joining of the connecting socket can be made considerably easier in accordance with the features of claim 8 in that the inside diameter of the socket receptacle of the connecting part in the region of the socket foot piece is smaller than that of the remaining socket receptacle. Until the socket base has reached the areas with the smaller inside diameter of the socket receptacle, the plug-in socket can be used with extraordinary Push little effort into the connector.
  • connection socket itself can be used as a temperature measuring element.
  • FIG. 1 shows an overall perspective view of a connection socket 1 according to the invention.
  • the connection socket 1 comprises a connection part 2 and a contact part 3.
  • the connection part 2 and the contact part 3 are designed as separate components.
  • connection part 2 has a solder pin 4 at its end facing away from the contact part 3.
  • the entire connector part 2, including the solder pin 4 is with a Tin coating or consists of a tin alloy through and through.
  • the contact part 3 which is shown as a separate component in Figure 2, however, is provided with a gold plating.
  • a crimp or crimp sleeve 5 is attached to the connecting part 2 instead of the soldering pin.
  • connection part 2 has an elongated, tubular socket receptacle 6 at its end facing away from the solder pin 4 or the crimp sleeve 5.
  • the contact part 3 is designed as an elongated, tubular plug-in socket (see FIG. 2), the outer diameter of the plug-in socket 3 being adapted to the inner diameter of the socket receptacle 6 of the connecting part 2 in such a way that both components can be press-fitted to form the connection socket 1 (cf. Fig.1).
  • the plug-in socket 3 is provided with approximately diametrically opposed longitudinal slots 7 which delimit elongated tongues 8 between them.
  • the longitudinal slots 7 or tongues 8 extend from the open socket end 9 to approximately a socket foot piece 10 which closes the plug-in socket 3.
  • the annular bead 11 is approximately 1/5 of the way from the socket foot piece 10 to the open socket end 9.
  • the outside diameter of the annular bead is larger than the inside diameter of the tubular socket receptacle 6 of the connecting part 2.
  • FIG. 2 shows particularly clearly that the annular bead 11 has an insertion bevel 12 rising from the direction of the socket foot piece 10.
  • the socket foot piece 10 is cylindrical, the length of the socket foot piece 10 corresponding approximately to the diameter of the same in the exemplary embodiment shown here.
  • the socket base 10 On its outside of the cylinder, the socket base 10 has a spline 13 with a plurality of longitudinally Direction of the socket 3 extending, radially projecting teeth.
  • the inner diameter of the socket receptacle 6 in the region 14 of the socket foot piece 10 is smaller than the diameter of the remaining socket receptacle 6.
  • the open socket end 9 is reinforced so that when a plug contact is inserted, it is guided through an enlarged collecting funnel.
  • connection part 2 and contact part or plug-in socket 3 are stored separately from each other. If it is a connection part 2 provided with solder pin 4, this will be provided with a tin coating.
  • the contact part 3, however, will usually always be covered with a thin gold layer.
  • the socket 3 is inserted into the socket 6 of the connector 2. First of all, this is done without great effort, since the inner diameter of the socket receptacle 6 in the region of its open ends is larger than the outer diameter of the socket foot piece 10. However, as soon as the edge of the socket receptacle 6 the insertion bevel 12 of the ring-shaped Bead 11 touches, the effort is slightly greater, since the tongues 8 are pressed radially inward while overcoming a spring force. Then the plug-in socket 3 is pushed further until the spline 13 of the socket foot piece 10 reaches the area 14 of the socket receptacle 6.
  • connection part 2 leads to a practically inseparable connection between the connection part 2 and the contact part 3.
  • the resilient tongues 8 can deflect radially outward in an elastic manner. This ensures a tight fit of the connector.
  • the socket receptacle 6 radially surrounding the tongues 8 prevents the tongues 8 from being bent too far in the radial direction when the plug is inserted, which would result in a plastic deformation of the tongues 8. Due to the construction according to the invention, an elastic pretension of the tongues 8 is always maintained, even in the event of an unfavorable or improper insertion of the plug into the open end 9 of the connector 1 is not eliminated.
