Definitions

  • the invention relates to an electrical connector for contouring a device provided with flat contacts, the flat contacts of which are arranged in the region of an outer wall of the device, a connector housing intended for receiving the device having an end wall provided with at least one opening and contact springs being arranged in the connector housing. which are each fastened with a fastening section in the housing and with a spring section carrying a contact dome protruding outwards from the housing through an associated opening in the end wall, such that the respective spring section is brought up to approximately the region of the end wall by an associated flat contact of the device is pushable back.
  • the invention is preferably applicable for contacting mobile telephone handsets or similar devices.
  • FIG. 10 schematically shows the arrangement of a mobile telephone handset (cell phone) on a stationary receiving part (cradle), in which the invention is preferably used.
  • This arrangement thus comprises a connector housing 1, which in the example is designed as a vehicle slot for a handset 2.
  • a stationary connector contact set 3 is accommodated in the connector housing 1, while a corresponding mobile contact set 4 with flat contacts arranged on the outer wall of the mobile part is provided in the mobile part 2.
  • the aim of the present invention is to provide an electrical connector of the type mentioned, in which the spring travel of the individual contact springs required for the front-side contacting is ensured with the simplest and most assembly-friendly construction, but the exposed contact spring surfaces are kept as small as possible; In this way, all contact spring parts that are not directly involved in the contact itself should be protected against contact and contamination if possible.
  • this goal is achieved in that the spring section emerging from the housing of each contact spring is arranged under an insulating protective hood, which in turn is movably mounted in the housing and is biased by spring force through the breakthrough of the housing, with only the contact tip by a front window of the protective hood protrudes outwards.
  • each contact spring has its own protective hood.
  • a common protective hood for a group of contact springs or for all contact springs of a connector, a separate window being preferably left out in the protective hood for each contact tip. Partitions projecting inwards on the protective hood can be formed between the windows.
  • the preload of the protective hood to the outside is expediently generated by the respective contact spring or contact springs. Also the guiding and storage of the protective hood can be made by the contact springs below it.
  • the protective hood is mounted in the housing for a longitudinal movement perpendicular to the end face.
  • the protective hood can in each case be pivoted about an axis also parallel to the end face via a support arm arranged approximately parallel to the end face. With a correspondingly long support arm, this also results in an approximately vertical movement of the protective hood to the end wall or to the contact surface for the short movement section.
  • the support arm can also be a rigid lever that is biased by a spring, preferably by the contact springs themselves; the support arm can also be formed in this case by the contact springs themselves.
  • each contact spring has a deformation zone between the fastening section and the contact section, which has at least one spring arm running transversely to the direction of movement of the contact section.
  • a spring support made of insulating material is preferably arranged in the housing, to which the contact springs are fastened next to one another in at least one row.
  • the contact springs are arranged alternately offset from one another by 180 ° in oppositely open chambers of the spring support, such that their contact tips lie in a single row, while their connecting lugs form two parallel rows on opposite sides of the spring support.
  • FIGS. 1 and 2 show a detail of an arrangement according to FIG. 10, a section of a stationary receiving part 1 and a mobile part 2 with a connector arrangement designed according to the invention.
  • a contact carrier 7 for individual contact elements 8 is provided on a circuit board 6 in the mobile part. These contact elements 8 are contacted on the printed circuit board 6 and form exposed flat contacts 9 towards the outside of the mobile part 2. These are to be contacted when the mobile part 2 is inserted into the receiving part 1.
  • a circuit board 10 is arranged in the stationary receiving part 1, on which a connector contact arrangement in the form of a female connector 11 is seated.
  • This female connector consists of a spring support 12 made of insulating material with a plurality of contact springs 13 and an insulating protective cover 14.
  • the female connector 11 is arranged on the circuit board 10 below an opening 15 provided in the receiving housing 1, so that the contact springs over the opening 15 with the flat contacts 9 come into contact.
  • the spring support 12 has fastening chambers 16 which are open alternately from opposite sides and into which the individual contact springs 13 are inserted alternately from opposite sides with U-shaped fastening sections 17.
  • the lower legs 17a of these fastening sections are fastened in the spring chambers 16 by clamping their side edges or in some other way, while the upper legs 17b can bend freely (see FIG. 2).
  • This upper leg 17b is already part of a likewise U-shaped deformation zone 18 of the contact spring, which is followed by a contact section 19 extending approximately perpendicular to the end wall 33 of the receiving housing 1.
  • This contact section 19 extends through the opening 15 of the housing to the outside and is curved hairpin-shaped at its outer end to form a contact tip 20 as the actual contacting zone of the contact spring.
  • the free end of the contact spring is angled into a hook 21, which engages on the inside of a web 22 of the protective hood and presses it out through the opening 15.
  • the protective hood 14 covers the entire row of contact springs 13 and forms a spring chamber 23 with a window 24 open to the outside for the contact section 19 of each contact spring, through which the contact tip 20 is exposed to the outside. Partitions 25 isolate the individual spring chambers from one another. Stop shoulders 26 of the protective hood, in cooperation with the inner edges of the opening 15, limit the movement of the protective hood 14 to the outside.
  • the identically designed contact springs 13 are inserted alternately rotated by 180 ° from opposite sides into the fastening chambers 16 of the spring support 12.
  • the protective hood is placed on the contact springs and connected to the spring carrier by snapping into place.
  • locking cams 27 provided at the ends of the protective hood are latched to end tabs 28 with snap hooks 29 of the spring support 12. This latching allows a free movement of the protective hood 14 against the spring force inwards. It is also designed so that both parts can move slightly tilted to each other.
  • the contact springs each have terminal lugs 30 which are designed as SMT connections and are soldered to contact surfaces of the printed circuit board 10.
  • the female connector is contacted and fastened on the printed circuit board, the arrangement itself being additionally stabilized by the oppositely inserted fastening sections 17.
  • the function of the connector arrangement can be seen from FIGS. 1 and 2.
  • the contact sections 19 of the contact springs are in the spring chambers 23 of the protective hood 14.
  • the contact tips 20 look through the small windows 24. 2, the contact surfaces of the flat contacts 9 on the mobile part are pressed against the contact tips 20 of the female connector 11.
  • the contact tips 20 move downward in the axial direction, the angled hooks 21 detaching from the protective hood 14.
  • the protective hood 14 can then freely move downwards together with the contact tips. Stop surfaces 31 on the protective hood, together with the stop surface 32 on the top of the spring support, limit the spring travel. In this way, excessive deformation of the contact springs is avoided.
  • FIGS. 6 to 9 A further embodiment of the connector according to the invention is shown in FIGS. 6 to 9. Insofar as the parts are the same or equivalent, they have the same reference numerals as in the previous exemplary embodiment.
  • a circuit board 10 is therefore arranged in the receiving housing 1, on which a somewhat modified female connector 41 is now attached. This consists of a spring support 42, a row of contact springs 43 and a protective hood 44. The contact springs are fastened in a row next to each other with a fastening section 47 on the spring support 42, the insulating distance being increased by an alternating height offset.
  • a spring arm 52 arranged approximately parallel to the end wall 33 in each case forms a deformation zone.
  • the protective hood 44 has separate spring chambers 45, in each of which a contact section 46 of a contact spring 43 is arranged.
  • a contact tip 48 projects through a window 50 to the outside.
  • the contact sections 46 are otherwise designed the same or similar to the contact sections 19 in the previous embodiment, so that a description of the details is not necessary.
  • the protective hood 44 is provided in this case with an integrally formed support arm 49, which is arranged approximately parallel to the end face 18 of the receiving housing 1 in the housing and is pivotably mounted via bearing pins 51. Due to the length of the support arm 49, the actual protective hood 44 also has a movement approximately perpendicular to the end face 18, so that the function during the contacting process in this exemplary embodiment is the same as in the previous one. As can be seen from FIGS. 8 and 9, the protective hood 44 is latched with latching lugs 53 in windows 55 by lateral tabs 54 of the spring support 42 - with free mobility inwards.
