Definitions

  • the present invention relates to electrical connectors and more particularly but not exclusively to such connectors for effecting the connection of printed circuit cards.
  • Printed circuit cards have in the past had the ends of the tracks thereon coated with noble metal for direct connection.to edge connectors in a mounting frame. If for any reason it is necessary for the cards to be removed and replaced many times, it is likely that wear of the noble metal coating will lead to a high resistance or open circuit contact. Such a fault on one or two of the contacts may necessitate replacement of the entire card.
  • contacts of any connector should be firmly located within their housings to facilitate the assembly of the housing which, depending on the particular design, necessitates inserting each contact in channels in the housing from either the front or rear of the connector. Such location is usually achieved on assembly by providing in the housing a shoulder or abutment to which a portion of the contact comes up in the direction of insertion. A spring portion of the contact then enters an aperture in the housing or a resilient portion of the housing moves behind-a portion of the contact to prevent the withdrawal of the contact in the opposed direction. To replace a contact the spring portion (or resilient portion) is moved aside by use of a suitable tool to enable the contact to be withdrawn from the same end of the connector as that through which it was inserted.
  • an electrical connector of the kind comprising a one-piece moulded housing of electrically insulating material shaped to receive an electrically conductive contact number
  • the housing has a first abutment arranged to co-operate with a resilient tine of a fully inserted contact to prevent movement of said contact in one direction and a second abutment arranged to co-operate with a portion of a fully inserted contact to prevent movement of said contact in an opposed direction, said tine being positioned such that it may be displaced clear of said first abutment to permit removal of said contact member in said one direction and said contact being arranged to pivot under pressure to cause said portion to be displaced clear of said second abutment to permit removal of said contact member in said opposed direction.
  • the contact member includes a part-spherical embossment arranged to co-operate with a surface provided in said housing to provide the pivot point for said contact.
  • Said housing may be arranged to hold a plurality of contact members each arranged to be withdrawn as aforesaid.
  • the electrical connector may be an edge connector for use with printed circuit cards.
  • the connector has a one piece moulded plastics housing 1 which has a number of connector segments 2 arranged vertically in pairs. Each of the connector segments 2 is arranged to hold an electrical contact 3 a first section 4 of which is for connection to a printed circuit board 5.
  • a plated section 5 is provided which is for insertion in a typical printed circuit board edge connector (not shown).
  • the contact 3 which is formed by for example pressing out from a phosphor bronze strip has an aperture 6 in the section 4 to facilitate soldering to a printed circuit board and is pre-stressed as shown in the diagram. It will be noted that the pre-stressing causes the rear of the contact to be displaced from the section 4 to assist locking of the contact 3 when it is inserted in a housing. Two resilient tines 7 are provided one on either side of the contact. 3 also for locking purposes.
  • a partially spherical embossment 9 is provided, the purpose of which is to facilitate removal of the contact 3 as hereinafter described.
  • a contact 3 may be inserted in one of the segments 2 from either the front or rear of the connector in the following manner:-
  • the connector is inserted from the front (the right as shown in the diagram) the rear of the contact 3 is inserted and passes through an aperture in the housing 1 and along a dividing wall 10 of the housing 1.
  • the tines 7 will flatten under the resilience of the material of the contact member so that they also pass through the aperture.
  • Removal of the contact is a matter of causing the tines 7 to adopt a flattened position so that they are clear of the face 12. The contact may then be pulled forward.
  • the contact 3 is inserted from the rear of the connectors (the left as shown), the front end of the contact member is inserted in the aperture of the housing 1 and the contact is pushed forward until the tines 7 meet the face 12. Releasing the rear of the contact 3 causes the rear of the contact 3 to drop into its respective channel under the pre-tensioning with its end adjacent the abutment 11.
  • the contact 3 has two ti.nes 7, a single tine could be provided. However, if two tines 7 are provided as shown the centre of the aperture through which the contact passes may be larger than the outer edges thus facilitating insertion of the contact without overstressing of the material.
  • the connector herein described is a particular form of intermediate connector between a printed circuit board and an edge connector
  • the design of the contact may be varied to provide for example an edge connector to which the present connector may be fitted.
  • the abutment 11 could be provided forward of the rear of the housing 1 and could be arranged to lock with a corresponding shaped abutment of the contact so that the contact 3 could be clear of the housing to facilitate connection thereto by wire-wrapping or soldering for example.
