  • Such a socket-type multipolar electrical connector is for example known from EP-A-0 123 590.
  • the socket-type multipolar electrical connector When a socket-type multipolar electrical connector is used together with its counter connector or plug-type multipolar electrical connector in which all the terminal pins are arranged in a predetermined assembly pattern with high density, the socket-type multipolar electrical connector is required such that all the contact pieces thereof corresponding to the terminal pins are also arranged in the same assembly pattern with high density.
  • socket-type multipolar electrical connector capable of satisfying the requirement above-mentioned, which has contact piece groups comprising a plurality of contact pieces all of which are assembled with the body of the connector with the horizontal pitch between each adjacent contact pieces being fine.
  • this plug-type multipolar electrical connector is arranged such that the terminal pins are divided into a terminal pin group for thin conductors and a terminal pin group for thick conductors, wherein the horizontal pitch between each adjacent terminal pins of the terminal pin group for thin conductors is substantially smaller than the horizontal pitch between each adjacent terminal pins of the terminal pin group for thick conductors, the terminal pin group for thin conductors is disposed at the center of the body made of an insulating material, and the terminal pin group for thick conductors is disposed at a lateral side of the terminal pin group for thin conductors.

  • the layout and the horizontal and vertical pitches of the plurality of first and second contact pieces forming the contact piece groups can fit in with the layout and the horizontal and vertical pitches of terminal pin groups for thin and thick conductors of a plug-type multipolar electrical connector using a composite cable. Accordingly, such a plug-type multipolar electrical connector can be used as a counter connector. Further, by connecting the plurality of first contact pieces to the thin conductors of the composite cable and by connecting the plurality of second contact pieces to the thick conductors of the composite cable, the respective contact pieces can be readily connected to the respective conductors of the composite cable having different diameters. Accordingly, the socket-type multipolar electrical connector of the present invention can be miniaturized with the density of the contact pieces increased.

  • the layout or arrangement of the terminal is generally similar to the layout or arrangement of the contact pieces. More specifically, it means that, when the contact pieces are arranged in a grid manner, the terminals are also arranged in a grid manner.

More specifically, the arrangement of the respective terminals 71 forming the terminal group 7 is generally similar to the arrangement of the respective contact pieces 41 forming the contact piece group 4.
  • the terminals 71 are basically arranged in a grid manner in the transverse and longitudinal directions.
  • the transverse pitch between each adjacent terminals 71 is the same as the horizontal pitch P1 between each adjacent contact pieces 41.
  • the longitudinal pitch of the terminals 71 is slightly greater than the vertical pitch of the contact pieces 41. With such an arrangement, the terminals 71 can be regularly arranged. This is useful for simplifying the production steps.
  • the assembly pattern of the terminal holding holes 81 in the terminal holder 8 is the same as the assembly pattern of the terminals 71 forming the terminal group 7.
  • the terminals 71 forming the terminal group 7 are respectively inserted into the terminal holding holes 81 of the terminal holder 8, and the terminal holder 8 is fitted into the opening 1b (See Fig. 10) at the bottom of the rearward portion of the body 1 as shown in Fig. 6 or 8. Accordingly, the terminal holder 8 not only securely maintains the terminals 71 in a predetermined pitch, but also prevents the contact pieces 41 from being positionally shifted in the rearward direction R. Further, the terminal holder 8 can maintain the shapes of the terminals 71. This causes the terminals 71 to be hardly deformed even though each of the terminals 71 is made in the form of a very slender piece.
  • the concave portions 82 of the terminal holder 8 are fitted to the plate portions 19 of the body, 1 and the engagement projections 83 of the concave portions 82 are engaged with the engagement grooves 19b (See Fig. 10) of the plate portions 19, as shown in Figa. 5 and 8.

  • the terminal holder 8 closes the opening 1b at the bottom of the body 1.
  • Such an arrangement provides an excellent shielding function as an anti-noise measure.
  • the terminals 25, 26 integrally formed at the shield cover 2 are grounded. This further improves the connector in shielding performance.
  • a space 9 (See Figs. 4 and 7) into which a case-like shield cover 100 of a plug-type multipolar electrical connector to be discussed later, can be fitted. Since the upper and lower portions of the case-like portion 21 are formed asymmetrically with each other, the plug-side shield cover 100 can be fitted to the space 9 only in a predetermined orientation. This effectively prevents the plug-type multipolar electrical connector from being erroneously inserted.

  • the projections 511 of the movable pieces 510 are guided by the guides 21e of the shield cover 2, so that the movable pieces 510 pass through the guides 21e while the sliders 600 fitted in the concave grooves 14 are bent and inwardly displaced.
  • the tips of the sliders 600 come in contact with the inclined surfaces 14a of the concave grooves 14, as shown in Fig. 13.
  • the plug-type multipolar electrical connector is further inserted, only the movable pieces 510 are moved forward as shown in Fig. 14, and the sliders 600 which remain in contact with the inclined surfaces 14a, are prevented from being moved forward, so that the spring members 530 are compressed.
  • the projections 511 reach the engagement holes 21f formed in the shield cover 2.
  • the movable pieces 510 are outwardly displaced and reset due to the resiliency thereof, so that the projections 511 are fitted into the engagement holes 21f.
  • the sliders 600 are displaced and reset, and the sliders 600 are then pushed out by the spring loads of the spring members 530.
  • the sliders 600 are fitted between the shield cover 2 and the surface of the forward portion 11 of the body 1. Accordingly, the sliders 600 are backed up from the back sides thereof by the surface of the forward portion 11 of the body 1, thereby to prevent the movable pieces 510 from being inwardly displaced. Accordingly, even though the composite cable 400 or the strain relief 700 is pulled, there is no possibility of the projections 511 coming out from the engagement holes 21f. This prevents the plug-type multipolar electrical connector from unexpectedly coming out from the socket-type multipolar electrical connector.
  • the plug-type multipolar electrical connector For pulling out the plug-type multipolar electrical connector as connected to the socket-type multipolar electrical connector as shown in Fig. 15, from the socket-type multipolar electrical connector, the plug-type multipolar electrical connector can be pulled out in a direction shown by an arrow Y in Fig. 16 with the sleeve 710 held with the hand.
  • the engagement portion 711 of the sleeve 710 engaged with the rear ends of the base portions 610 of the sliders 600 pushes the base portions 610 in the forward direction F (See Fig. 1), so that the sliders 600 are retreated against the spring loads of the spring members 530.
  • F See Fig. 1
  • the sliders 600 come out from between the surface of the forward portion 11 of the body 1 and the movable pieces 510 to form gaps at the back sides of the movable pieces 510. This enables the movable pieces 510 to be inwardly displaced. Accordingly, when the plug-type multipolar electrical connector is further pulled out, the pulling force causes the projections 511 to be inwardly pulled out from the engagement holes 21f. Then, the movable pieces 510 and the shield cover 100 are pulled out from the shield cover 2, so that the plug-type multipolar electrical connector is removed from the socket-type multipolar electrical connector.
  • the projections 511 are engaged with the engagement holes 21f at the left- and right-hands of the both electrical connectors. This enables the inserting and pulling operations to be carried out in a well balanced manner.
