Definitions

  • the present invention relates to a static charge removal connector to make an electric connection between two printed circuit boards or other electrical parts.
  • Board-to-Board electric connectors have been widely used, and some electric connectors have been equipped with static change removal means to prevent the flow of static electricity from a person handling the connector to its terminals.
  • An example of such a static charge removal connector is shown in United States Patent No. 5,002,495.
  • the connector in this patent comprises a female receptacle which mates with a male plug.
  • the male plug has a plurality of flat male terminals attached to its housing.
  • the female receptacle has a plurality of terminals corresponding to the male terminals and springs on each end of the plurality of terminals with one end of the spring attached to a printed circuit board and the other end in contact with a hinged metal over.
  • the springs are designed to resiliently contact the inner surface of the metal cover and bias the cover in the open position.
  • the metal cover has hinges on its opposite sides and slots made on its major surface to allow the female terminals to appear above the metal cover only when the cover is in the closed position. Before the male plug is inserted in the female receptacle, the metal cover is in its raised open position, thus protecting all the female terminals between the raised metal cover and the top surface of the housing of the female receptacle.
  • One object of the present invention is to provide an improved static charge removal connector which requires simple manufacturing techniques by attaching a metal cover to a receptacle housing.
  • Another object of the present invention is to provide such a static charge removal connector equipped with a grounding metal cover, which is simple, stout and durable, guaranteed free of contamination or deformation of female terminals and allowing for minor variations in dimensions which could cause connector mismatch.
  • a static charge removal connector comprising a male plug including a male housing having a base, a mount, and at least one male terminal fixed to the mount, and a female receptacle including a female housing having at least one terminal mounting cavity and a flexible female terminal in the cavity.
  • the female housing has a metal cover integrally connected to ground bars and applied to a top surface of the housing where the cover has apertures through which the mount with the male terminal can be inserted.
  • the terminal mount projecting from a floor of the housing of the male plug, and physically dimensioned so as to permit insertion through the aperture in the cover and into a slot in the female housing.
  • the male terminal is fixed to the terminal mount with the contact section of the male terminal laid on the top of the terminal mount, thus permitting the contact section of the male terminal to come into contact with the contact section of the flexible female terminal when the male plug is mated with the female receptacle.
  • the female terminal which is yieldingly deformable remains contained within the slot of the female housing prior to making contact with the counter male terminal.
  • the female terminal comprises a base section having two ends mounted within the female housing, one end integrally connected to a solder tail section adapted to be connected to a trace on a printed circuit board and the other end integrally connected to a flexible bent section.
  • a flexible arm extending from the other end of the flat contact section supports that other end of the flat contact section. Support of the flat contact section by both the flexible bent section and the flexible arm allows the flat contact section to provide a generally equal force against a mating male terminal across the entire length of flat contact section.
  • the metal cover comprises front, rear and opposite side sections to cover corresponding front, rear and opposite side surfaces of the female housing.
  • the opposite side sections have ground pieces integrally connected.
  • a plurality of female terminals are contained within slots arranged at regular intervals in staggered relation in said female housing and a plurality of male terminals are arranged in the male housing at the same regular intervals in staggered relation as the intervals of the female terminals.
  • the terminal mounts of the male plug are inserted in the apertures of the receptacle housing until the male terminals come to contact the female terminals in the receptacle housing.
  • the dimensions of the male terminal mounts are smaller than the dimensions of the apertures allowing for a slight mismatch of the terminals due to slight variation in dimensions.
  • the static electricity is discharged from the body of the person handling the connector to the metal cover of the female receptacle.
  • the metal cover is fixed to the receptacle housing to cover its front, rear, opposite, side and top surfaces except for the apertures in the top surface through which insertion of the male terminal mounts and terminals is permitted.
  • the metal cover can be attached to the receptacle housing with ease, and therefore, permitting attachment by machine of metal covers to receptacle housing.
  • the metal cover is stout and durable because it is attached to the receptacle housing and because it has no moving parts. Also, the female terminals which are within and partially protected by the substantially closed housing providing freedom of deformation and contamination.
  • Fig. 1 shows schematically a male plug 21 and a female receptacle 1 of a static charge removal connector according to the present invention before mating with each other.
  • Fig. 2 schematically shows the male plug 21 and the female receptacle 1 when mated together.
  • the male plug 21 is attached to a printed circuit board 50 and the female receptacle is attached to another printed board 40.
  • Figs. 3 to 7 show the female receptacle 1 and Figs. 8 to 15 show the male plug 21 and associated male terminals 24.
  • the female receptacle 1 has a hollow housing 2 covered with a metal cover 11.
  • the housing 2 has a female terminal mount 3, which has a plurality of slots 12 in alignment with the apertures 41 made in the metal cover 11.
  • Female terminals 4 are fitted in these slots 12 of the female terminal mount 3.
  • the female terminal comprises a solder tail section 9, a base section 7, a bent section 5, a horizontal section 17, a steep-inclined section 18, a slow-inclined contact section 6, and a bend-and-return section 8 integrally formed in the sequentially consecutive named order.
  • the entire female terminal 4 is within the slot 12 of the female terminal mount 3, leaving nothing exposed.
  • the top surface 10 of the housing 2 is covered by metal cover 11 except for the apertures 41 in alignment with slots 12, thereby permitting insertion of terminal mounts 23 and the male terminals 24.
  • the cover 11 is adapted to cover the surface 10 of the housing 2, and at the same time to cover the front, rear and opposite sides of the housing 2.
  • the opposite sides 14 of the metal cover 11 have horizontal ground pieces 15 integrally connected thereto.
  • the male plug 21 has a housing 22 with a flat base 29 and terminal mounts 23 erected thereon.
  • Each terminal mount 23 is physically dimensioned so as to fit within slot 12 in the female receptacle 1.
  • the dimension of terminal mount 23 is smaller than the length of the aperture 41 and slots 12. This allows the curved contact section 26 of the male terminal 24 to travel along the contact section 6 of the female terminal and make electrical contact everywhere.
  • Male terminal 24 is fixed to each terminal mount 23 by fitting edges into grooves within the terminal mount 23 with its curved contact section 26 laid on the top of the terminal mount 23.
  • a male terminal 24 consists of a descending front extension 30, a curved contact section 26, a descending rear extension 31 and a horizontal rear extension or a solder tail 27 which are integrally formed together, consecutively in the order named.
  • the descending front extension 30 of the male terminal 24 is inserted in the longitudinal hole 32 in the terminal mount 23 whereas the descending rear extension 31 is fitted in the groove 33 in the terminal mount 23.
  • attaching piece 28 are integrally connected to the back surface of the base 29.
  • all female terminals 4 are concealed within the receptacle housing 2, particularly in the slots 12 of the receptacle housing 2.
  • the contact sections 6 of the female terminals 4 do not appear beyond the outside surface of the metal cover 11 in the decoupling position of the static charge removal connector. Therefore, the contact sections 6 of the female terminals 4 cannot be deformed or contaminated by inadvertent application of undesired forces.
  • the static electricity if any, will be discharged from the body of a person handling the static charge removal connector through the cover 11, thus assuring that such static electricity will not flow in the male or female terminals.
  • the male plug 21 is coupled with the female receptacle 1 by inserting the terminal mounts 23 of the male plug 21 through the apertures 41 of the cover 11 and in the slots 12 of the receptacle housing 2.
  • Each male terminal 24 will contact the counter female terminal 4 by their contact section 26 and 6, thus making an electric connection between the two printed boards 40 and 50.
  • the female terminals 4 are yieldingly bent at their bend sections 5 until the tips 42 of the bend-and-return sections 8 have contacted the terminal base section 7 which is just above the upper surface of the base 16.
  • the force of the bend-and-return section 8 supporting one end of the contact section 6 and the force of the steep inclined section 18 supporting the other end of the contact section 6 will ensure that contact section 6 will exert an equal upward force opposite the male contact section 26 anywhere along contact section 6. This will cause a good contact pressure on each male terminal.
  • the contact section 6 of each female terminal 4 will also be placed and maintained in a horizontal position, thus permitting even contact with the counter contact section 26 of the male terminal 24 at an increased area.
  • a plurality of slots 12 are staggered at regular intervals in the housing 2 of the female receptacle 1, each having a female terminal 4 located therein. Accordingly, the contact sections 6 of the female terminals 4 are arranged in staggered relation, as best seen from Fig. 6 and 7, which are cross sections taken along the line 6-6 and line 7-7 in Fig. 4. Likewise, a plurality of terminal mounts 23 are staggered on the base 29 of the male plug 21, and accordingly the male terminals 24 are staggered.
