Definitions

  • the present invention relates to an electric connector for use in making an electric connection between different electric devices, and particularly to an electric connector which is equipped with a cam mechanism to permit the mating of the connector plug with the connector receptacle with a reduce force.
  • connectors include more and more terminals. Consequently such connectors require if greater force to mate the numerous plug and receptacle terminals.
  • connectors be equipped with cam mechanisms, as for example in Japanese Utility Model Application Laid-Open No. 6-2577.
  • one part of the electric connector that is, the connector plug or connector receptacle has a projection formed thereon whereas the other counter part has a slot made therein for guiding the projection of the one part.
  • the projection follows the slot in such a way that the connector plug may be mated with the connector receptacle with a reduced mating force.
  • the cam mechanism has, in fact, the effect of reducing the mating force to be applied to the connector.
  • a draw back however, is that the parts needed to assemble a connector increase in number also the labor an time involved for assembling increases thereby increasing the overall cost of the connector.
  • One object of the present invention is to provide an electrical connector including a plug and a receptacle which is equipped with a cam mechanism to permit the mating of the connector plug with the connector receptacle with a reduced force and allowing the connector to be reduced in size and cost.
  • an electrical connector equipped with a cam mechanism allowing the mating of the connector plug with the connector receptacle with a reduced force is improved according to the present invention in that the connector plug has a housing with a space defined therein to accommodate the mating connector receptacle.
  • the connector receptacle has a housing and a protective cover slidably attached to the housing.
  • the cover is movable on the housing in a lateral direction perpendicular to the mating direction and the cam mechanism is capable of converting lateral displacement of the cover to the movement of the connector plug and the connector receptacle along the mating axis of the connector.
  • the cam mechanism includes at least one guide pin and a guide slot for guiding the guide pin.
  • the guide pin is located on the connector plug and the guided slot is formed in the slidable cover of the connector receptacle.
  • the guide slot may be so formed that the cam ratio may vary to permit the mating of said connector plug and connector receptacle without changing of the force applied to the protection cover even though the force required for mating the male terminals of the connector plug with the female terminals of the connector receptacle varies from the beginning of the mating process until the end.
  • one portion of the cam mechanism is integrally formed with the protection cover, thus requiring no extra parts for the cam mechanism.
  • an electrical connector As seen from Figs. 1 and 2, an electrical connector according to the present invention comprises a plug 1 and a receptacle 2.
  • the connector plug 1 is mounted on a printed circuit board (not shown), which is a part of an electrical machine or apparatus (not shown), whereas the connector receptacle 2 is connected to a plurality of wires 24 extending from another electrical machine or apparatus (not shown). These electrical machines can be electrically connected to each other by the mating of the connector plug 1 and the connector receptacle 2.
  • the connector is equipped with a cam mechanism 3 allowing the mating of the connector plug 1 with the connector receptacle 2 to take place with a reduced force.
  • the cam mechanism 3 is capable of converting lateral displacement of a selected part (later described) of the connector to the mating of the connector plug 1 with connector receptacle 2 while applying to the connector plug 1 the mating force caused by the lateral displacement of the selected part.
  • the cam mechanism 3 is composed of guide pins 5 and guide slots 6 for guiding the guide pins 5.
  • the connector plug 1 has a housing 11 and a plurality of plug terminals 12 mounted therein.
  • the plug housing 11 has a receptacle enclosing space 13 defined therein to accommodate the connector receptacle 2 upon mating.
  • the plug terminals 12 are arranged in the receptacle enclosing space 13, and the guide pins 5 are formed on the floor and ceiling of the receptacle enclosure of the plug housing 11, as best seen from Fig. 4.
  • the tail portions 14 of the plug terminals 12 appear on the rear side of the plug housing 11, as best seen from Fig. 5.
  • the tail portions 14 can be soldered to selected conductors of a printed circuit board to which the connector plug is to be attached.
  • the connector receptacle 2 has a housing 21 and a plurality of female terminals 22 mounted therein.
  • the receptacle housing 21 has a mating section 23 which enters the receptacle enclosing space 13 of the plug housing 11 upon mating.
  • a protective cover 26 is slidably attached to the major opposite surfaces of the receptacle housing 21 to cover the emerging lengths of conductors 24 extending from the female terminals 22 to an electrical machine or apparatus which is to be connected to the printed circuit via the electric connector.
  • the slidable, protective cover 26 has cam slots 6 located therein, particularly in the slidable section 27 lying over the mating section 23 of the receptacle housing 21.
  • Each cam slot 6 has a shape such that its cam ratio may differ from the pre-mating position to the post-mating position between the male and female terminals 12 and 22 of the connector plug and connector receptacle. More specifically the slot inclination relative to the longitudinal direction F in which the mating section 23 of the connector receptacle 2 enters the receptacle enclosing space 13 of the plug housing 11 may be at a relatively small angle prior to mating, and may be at a relatively large angle on the way to the final mating position, thereby assuring that little or no adverse effect is caused on the cam operation by the difference of the terminal mating force at the outset and sequential moment.
  • the cam slot 6 ends with the laterally positioned end 7, which extends somewhat in the lateral direction M perpendicular to the connector-mating direction F, thereby putting the male and female terminals in a stable mating condition.
  • the slidable protection cover 26 has lock pieces 8a and 8b for locating the protection cover 26 in the correct positions at the start and at the finish of the plug and receptacle mating, respectively.
  • Each lock piece has a catch projection 9a and 9b formed on its free end.
  • the lock piece 8a of the slidable protection cover 26 is engaged by the lock slot 25 of the receptacle housing 21, as shown in Fig. 10.
  • the lock piece 8a is released from the lock slot 25.
  • the lock piece 8b of the slidable protection cover 26 is engaged by the counter piece 15 of the plug housing 11, thereby holding the connector plug and receptacle in a mated condition.
  • the receptacle housing 21 has a catch projection 28 to catch a wire-binding strap 29.
  • the strap 29 is used to wind and bind conductors 24 emerging from the connector receptacle 2 into a bundle, thereby placing the bundle of conductors apart from the area in which the slidable protection cover 26 moves to prevent any jamming with the bundle of connectors, which otherwise, would be caused by interference with the moving cover 26.
  • the slidable protection cover 26 may be designed to be movable in either direction, and in this particular embodiment it can move in the left lateral direction as indicated by arrow M.
  • the direction in which the slidable protection cover 26 can be moved may be determined which way the connector is formed or in which direction the bundle of conductors 24 extend.
  • the catch projection 28 may be formed accordingly on either side of the housing 21.
  • the connector receptacle 2 and the connector plug 1 are put in an opposite relationship, and then, the connector receptacle 2 is moved in the longitudinal direction F until the mating section 23 of the receptacle housing 21 is received in the receptacle enclosing space 13 of the plug housing 11, as shown in Fig. 11. In this position, the guide pins 5 of the plug housing 11 enter the guide slots 6 of the protection cover 26 of the connector receptacle 2.
  • the catch projection 9a of the lock arm 8a formed on the protection cover 26 is engaged by the lock slot 25 of the receptacle housing 21 (Fig. 10), thereby placing the protection cover 26 and the guide slots 6 in correct positions.
  • the protection cover 26 is moved in the lateral sliding direction M perpendicular to the longitudinal mating direction F, thereby causing the displacement of the connector receptacle 2 in the mating direction F by allowing the guide pins 5 to follow the guide slots 6 thereby permitting the continuing insertion of the mating section 23 of the receptacle housing 21 into the receptacle receiving space 13 of the plug housing 11.
  • the catch projection 9a of the lock piece 8a is automatically released from the slot 25 of the receptacle housing 21.
  • the protection cover 26 is moved further in the lateral direction M until the connector plug and connector receptacle 1 and 2 have been completely mated.
  • the mating operation is composed of three sequential steps: at the first step the mating section 23 of the receptacle housing 21 is fitted in the receptacle receiving space 13 of the plug housing 11, but the mating of the plug and receptacle terminals 12 and 22 is not started (Fig. 12); at the second step the mating of the plug and receptacle terminals 12 and 22 is started (Fig. 13); and finally at the third step the mating of the plug and receptacle terminals 12 and 22 is completed (Fig. 14).
  • Each mating step has a different cam ratio to control the varying terminal mating force so as to cause no effect on the operating force which is applied to the cam mechanism before and after the starting of the mating of the plug and receptacle terminals 12 and 22.
  • the slidable protection cover 26 can be moved by applying a given constant force thereto all the way to the final position in the lateral sliding direction M.
  • the connector plug and receptacle 1 and 2 can be mated by applying a constant force of reduced strength to the protection cover 26 of the connector receptacle 2.
  • the positive, reliable mating is assured by permitting the catch projection 9b to be engaged by the counter piece 15 of the plug housing 11, as shown in Figs. 15 and 16.
  • the catch projection 9b can be released from the counter piece 15 of the plug housing 1 simply by pushing the lock arm 8b.
  • the decoupling of the connector plug and receptacle can be performed by the reversal of the proceedings described above.
  • the guide slots 6 of the cam mechanism 3 are formed in the slidable protection cover 26, thus requiring no extra separate parts to make up the cam mechanism. This has the effect of reducing the number of the assembled parts of connector plug and receptacle, and accordingly reducing the connector size and the manufacturing cost.
  • the connector plug housing 11 has guide pins 5 located in its receptacle receiving space 13, and the connector receptacle has guide slots 6 in its protection cover 26. Conversely, the connector plug housing 11 may have guide slots 6, and the connector receptacle may have guide pins 5 in its protection cover 26.
