Definitions

  • the present invention relates to lock mechanisms for locking the connection of two electrical connectors (see EP-A-0 285 860).
  • Japanese U.M. patent application Kokai No. 63-172070 discloses a lock mechanism for electrical connectors which includes a pair of separate engaging metal fittings incorporated on the opposite sides of the insulation case of an electrical connector for engagement with the engaging metal fittings of a mating electrical connector for locking the connection of the two electrical connectors.
  • the engaging metal fittings are secured to the insulation case by fixtures on opposite sides, and the engaging portions are provided between these fixtures.
  • a lock mechanism for an electrical connector which includes a pair of extended sections each having a lock projection for engagement with a lock hole of a mating electrical connector; a linking arm for connecting the extended sections; a pair of press-fit portions with a metal fitting engaging projection for engagement with a press-fit groove of an insulation housing; and a pair of U-shaped sections for connecting the extended sections and the press-fit sections.
  • an electrical connector in Fig. 1, includes upper and lower case halves 10 and 11 made from an insulation material, such as a plastic, an insulation housing 30 to be placed in the case, and an engaging metal fitting 40 to be mounted on the insulation housing 30.
  • a mating electrical connector is mounted on a printed circuit board 1, for example, and includes an insulation housing 3 having a number of contacts arranged therein.
  • a pair of engaging metal fittings 4 are mounted on opposite sides of the insulation housing 3.
  • Each metal fitting 4 has an engaging hole 5 at the front portion and a ground extension 4A at the rear portion. The ground extension 4A is soldered at 2 to the ground conductor 1A of the board 1.
  • the upper case half 10 has at the front portion a receiving cavity for receiving the rear portion of the insulation housing 30 and at the rear portion a cable receiving port 11.
  • a pair of knob openings 12 are formed on opposite side walls of the upper case half 10.
  • a pair of holes 13 are provided on the upper case half 10 for fastening the upper case half 10 to the lower case half 20 with a pair of screws 14.
  • the lower case half 20 has a cable receiving port 21 and a pair of knob openings 22.
  • a pair of threaded holes 23 are provided for receiving the fastening screws 14.
  • a cable fixture receiving recess 24 is formed on the cable receiving port 21.
  • a cable fixture receiving recess similar to this is formed on the cable receiving port 11 of the upper case half 10.
  • the insulation housing 30 is made from an insulation material, such as a plastic, so as to have a number of contact channels 31 for receiving contacts as the insulation housings of ordinary connectors.
  • a pair of press-fit grooves 32 are formed on opposite sides of the front portion of the insulation housing 30.
  • the engaging metal fitting 40 is made from a springy metal sheet by stamping and forming so as to have a pair of extended sections 41, a pair of press-fit sections 43, a pair of U-shaped sections 42 between the extended sections 41 and the press-fit sections 43, and a linking arm 44 for connecting the press-fit sections 43.
  • the end portion of each extended section 41 is provided with a pair of knob retaining projections 46.
  • An lock projection 48 is stamped out from the front portion of the extended section 41.
  • An inwardly projecting reinforcing rib 47 is provided between the knob retaining projection 46 and the lock projection 48.
  • Each press-fit section 43 has a pair of metal fitting retaining projections 45.
  • a pair of knobs 50 made from a plastic, for example, so as to have a corrugated top so that it is easy to push for unlocking the connection of two connectors.
  • the knobs 50 have a groove for engaging the knob retaining projections 46 to secure them to the engaging fitting 40.
  • the insulation housing 30 is placed in the lower case half 20 so that the knobs 50 and the multiconductor cable 6 fit into the knob engaging openings 22 and the cable receiving port 21, respectively, and the multiconductor cable 6 is secured to the cable receiving port 21 with a cable fixture 8.
  • the upper case half 10 is secured to the lower case half 20 with fastening screws 14.
  • the engaging grooves 32 are formed on the side walls of the insulation housing 30 for receiving the engaging metal fitting 40 to secure the engaging metal fitting 40 to the insulation housing 30.
  • Fig. 3 shows, it is possible to secure the engaging meal fitting 40 to the lower case half 20A by wedging the metal fitting retaining projection 45 into the press-fit grooves 26 of an inner wall 25 which is provided on the lower case half 20A.
  • the engaging metal fitting 40 may be secured to the upper case half in the same way.
  • the engaging metal fitting 40 is secured to the lower or upper case half instead of the insulation housing 30, it is easy to insert contacts into the insulation housing 30.
  • the connected cable does not interfere with the attachment of the engaging metal fitting 40.
  • an engaging metal fitting 40A has a press-fit portion 49 extending from the center of a linking arm 44A.
  • the press-fit portion 49 has a pair of engaging projections 49A.
  • the insulation housing 30A is provided with a guide projection 33 on the central front portion.
  • the guide projection 33 has a press-fit opening 34.
  • the insulation housing 3A of the mating electrical connector is provided with a guide recess 3B for receiving the guide projection 33 of the insulation housing 30A. In this way, it is possible to reduce the width of the insulation housing.
