  • the main body 51 has an elastic stopper 55 as well as a guider 57 on each side end thereof.
  • the operating member 62 has a gripe 69 and an insert 64 on each side end thereof. Each of the insert 64 is inserted into a corresponding receiving hole 60 of the main body 51.
  • the operating member 62 is reliably prevented from an accidental separation from the main body 51 by a stop protrusion 67 and an auxiliary protrusion 68.
  • a pair of protrusions 67 and 68 is provided on the outer surface of each insert 64 of the operating member 62.
  • a plurality of terminals 53 is upwardly inserted into the corresponding lead receiving holes 61 of the main body 51.
  • Fig. 2 is a cross sectional view along the section line I - I of Fig. 1 of the prior art connector, which is provided with the cable leads 72.
  • a lead 72 of cable 71 inserted into the connector is reliably positioned by an elastic part 59 of a corresponding terminal 53 as well as by a corresponding projections 66 of the operating member 62.
  • the cable leads 72 are inserted into the connector before the projections 66 and the terminal 53 are inserted into the main body 51.
  • the projections 66 of the operating member 62 are inserted in order to fixedly support the cable leads 72 at their predetermined position with respect to the main body 51.
  • the terminals 53 having individual elastic parts 59 are inserted from the bottom into a terminal inserting hole 54 of he main body 51 so as to fixate the cable leads 72 at their predetermined position in cooperation with the projections 66 of the operation member 62.
  • each of the inserted terminals 53 is prevented from accidental separation from the main body 51 since an elastic projection 58 of the terminal 53 is elastically engaging a corresponding recess 61a formed on an inner surface of a side wall of the main body 51.
  • Fig. 3 shows a side view of the prior art connector in which the inserts 64 of the operating member 62 are received by the main body 51.
