Definitions

  • This invention relates to electrical connector structures which are comprised of an assemblage of selected preexisting interfitting modules.
  • Another country may have a standard requiring a termination end be such the mating face is at right angles to a orinted circuit board surface.
  • Another country may have a domestic standard calling for the termination of the connector by the conductors of a multiconductor flat cable.
  • Still another country may have a domestic standard specifying that each connector contact be individually terminated by the insulation displacement termination of solid or stranded wire, etc.
  • a low cost way of meeting at least part of such worldwide market requirements is to provide a modular electrical connector construction which is made up of a molded olastic common housing which defines the mating portion of the connector and which includes a generally open-ended cavity.
  • a plurality of molded plastic insert members are then provided in the form of a set of contact supporting modules each defining a different termination configuration for the connector.
  • Each of the modules is formed so as to interchangeably nest in and substantially fill at least one end of the cavity in the common housing.
  • Each of the contact sudporting modules in a given set supports a plurality of contact elements having mating ends which conform to the mating portion of the housing and termination ends which conform to the particular termination portion of the connectors as defined by the specific contact supporting modules within the cavity of the housing.
  • the higher cost of tooling typically required for molding the common housing portion of a connector meeting international mating standards can be offset to a large extent by mass producing such housings at one or a relatively few strategically located primary locations within one or more countries embraced by the international market area of interest. Such housings may then be shipped to any of a larger number of secondary locations in a greater number of countrtes embraced by the market area. At these secondary locations the lower cost contact supporting modules meeting specialized domestic standards of a secondary location country can be manufactured and assembled into the common housing for sale in that domestic market.
  • Such modular connector, its method of manufacture and tooling enabling its manufacture are disclosed and claimed in a copending patent application assigned to the same assignee as the present invention.
  • a single common housing is provided along with a single set of different snap-in contact supporting modules each one defining a respectively different termination configuration for the housing and each supporting a plurality of contacts.
  • all of the contacts in any module of the set have identical mating ends.
  • the termination ends of all of the contacts in each different module conform the particular termination configuration defined by that module.
  • the mating face of the common housing with a snap in contact in place is such that it will mate with a non-modular standard connector.
  • the present invention takes advantage of certain features of the aforesaid modular connector structure in combination with certain improved structural features which enable complete subsets of different connector series to be produced in modular form.
  • complementary plug and receptacle type connectors are mateable with each other as well as with complementary nonmodular standard connectors.
  • the individual male and female contacts supported within selected modular plug ana receptacle connectors are field serviceable or replaceable. The attendant increased product versatility which is thereby afforded allows a greater part of the international market to be served with higher cost savings.
  • an entire series or family of connectors is categorized into subsets with the basic elements of each subset being intermateable plug and receptacle housings for a given connector size. Molded plastic inserts, carrying male or female contacts, are then provided in as many different conductor termination configurations as may be desired.
  • a modular electrical connector may be realized which constitutes one member of a subset of a pluraltiy of different subsets making up a family of intermateable modular electrical connectors.
  • Each connector is distinctly different from any of the others in the subset and each carrying electrical contacts with each one of the connectors in the subset having an outer housing end of either receptacle or plug configuration.
  • Any given member of the subset having an outer housing mating end or face of plug configuration is intermateable with any other given member of the subset having an outer housing mating face of receptacle configuration and vice versa.
  • the conductor termination end of any given member of the subset is differently configured from the conductor termination end of any given member of the subset.
  • the modular electrical connector so characterized comprises: an outer housing element corresponding to either a plug configuration or a receptacle configuration, each complementary to the other, said housing element having a mating face defining the front outer face of said modular connector, said mating face having an electrical contact access opening means therein for receiving electrical contacts carried by any other connector member of said subset having a complementary mating face;
  • contact restraining means supported within the housing and having a plurality of contact receiving openings extending generally between the mating face and the rearward portion of said housing, the rearward tranverse surface of said restraining means being displaced from the rear surface of the housing to form a generally open-ended cavity;
  • a male connector generally designated 10 and a female connector generally designated 12 which are intermateable with one another ana each comprising one member of a subset of a plurality of different subsets making up a complete family or series of modular electrical connectors.
  • a subset of a connector series or family comprises a plurality of distinctly different connectors having certain common mating features.
  • a connector within any given subset has a mating portion (or face) of either a plug or a receptacle configuration with either configuration being complementary to the other and therefore intermatable with the other. All connectors in any given subset also have the same number of contacts with complementary male and female mating ends, and with all contacts being positioned such that complementary male or female contacts held within complementary plug and receptacle connectors will mate upon the intermating of the connector.
  • any member of a given subset in accordance with the present invention, can be provided with different conductor termination configurations for use with printed circut boards, flat cables, solid or stranded wire insulation displacement, etc.
  • a male electrical connector 10 in accordance with this invention is comprised of a receptacle outer housing element 14 having front or mating face configuration 16 with an access opening 18 sized and shaped to received the outer housing element mating face configuration 20 of the female connector 12 shown in Figure 2.
  • the male contacts 17 adjacent the dielectric center wall 17' of male connector 10 are received into contact access ooening 19 of female connector 12 to mate with female contacts 32 adjacent the peripheral dielectric wall 21 within the female connector 12.
  • the connector 10 of Figure 1 may be characterized as a male connector with a receptacle housing and the connector 12 of Figure 2 a female connector with a plug housing.
  • housings such as 14 and 22 in any given subset may, depending on type of contacts used in the connector and especially where pin and socket type contacts are used, be supplemented by and interchanged with reciprocally sized housing elements.
  • a receptacle housing with male pin contacts is replaceable by plug housing having male contacts
  • plug housing with female contacts is replaceable by a receptacle housing having female contacts.
  • the receptacle outer housing 14, its complementary plug housing element 22 and their reciprocal counterparts are adapted to receive one of a plurality of different molded plastic contact supporting modules, such as 24 and 26, within a cavity formed in the rear of each housing element. This can better be seen by referring to Figure 3.
  • the outer housing element 22 of female connector 12 is shown formed with a contact restraining means or web 28 having a transverse rear surface 29 displaced from the rear outer surface 29' of the housing element to form a generally open-ended cavity 30.
  • the molded plastic contact supporting module 26 supporting contacts 32 within recesses 34 therein, (see also Figures 5 and 7) may then be nested in the cavity 30 with contacts 32 passing through contact receiving openings 36 in the contact restraining web 28.
  • the latching action is preferable accomplished by means of the upper surface of the hook portion 42 formed in each boss engaging the forward-most surface of the contact restraining web 28 or a rear surface of a ledge formed in latch openings 40 when the module is nested within the cavity 30.
  • complementary keying means in the form of a transversely extending nib or projection 44 and a registering recess (not shown) in the right hand edge surface 46 of the module 26 ensures that the module 26 can be positioned in the cavity 30 in only one orientation relative to the housing 22. This preserves the integrity of the contact numbering system used to assign indices to the various contact receiving recesses 34 for proper complementary matching with correspondingly numbered cavities in a mating connector.
  • the form of the female contact 32 is of an insulation displacement type for use with solid or stranded insulation wire.
  • the mating male and female contacts 32 and 58 ( Figure 4) are of a form similar to that shown in U.S.Patent 3,867,005 entitled "Insulation - Piercing Contact Member and Electrical Connector” and assigned to the assignee of the present invention.
  • the mating portions 32' and 58' of these contacts are configured differently from those shown in U.S.
  • Patent 3,867,005 so as to permit assembly of the contacts through the contact receiving openings such as 36 in the contact restraining webs of the housing members 14 and 22 to ultimately engage the contact preloading means 50 and 50' in the plug and receptacle housings.
  • the insulation displacement termination portion 32" and 58" of contacts 32 and 58 are, however, substantially the same as that shown in the aforereferenced patent and includes two pairs of detents such as 56 in contact 32 extending from opposite sidewalls of a U-shaped channel in the contact (see Figure 7), with the space between the detents comprising a notch 56' which will displace the insulation on solid or stranded wire when forced therein to effect an electrical termination of the contact to the conductor of the wire.
  • the male contact for use in male connector 10 shown in Figure 1 is reciprocal in form to the female contact 32 shown in Figure 4B, that is to say the mating surface 58' of contact 58 is on the same side of the flat blade as the insulation displacement terminating portion 58" while for the female contact 32 the insulation displacement termination portion 32" is on the opposite of the female contact surface 32'.
  • each of the contact members shown in Figure 4 are provided with raised portions 60 in the form of dimples or the like. As shown in Figure 7, it is the function of these raised portions 60 in combination with the inner side-walls of the forwardmost portion of cavities 34 within the contacts supporting module 26 to provide means for frictionally maintaining contacts within a contact supporting module prior to the nesting of the module into a housing.
  • molded plastic contact supporting modules in accordance with the present invention can be assembled and put into inventory for later selection and insertion into selected outer housing elements such as 22 shown in Figure 3 without the contacts inadvertently becoming displaced from the module during handling.
  • Figure 6 illustrates a cross-sectional view of the male modular connector shown in Figure 1 taken on a plane defined by line 6-6 looking in the direction of the arrows, and made up of receptacle outer housing element 14 with a male molded plastic contact supporting module 24 nested within a cavity 62 in the rearward portion of the outer housing element 14.
  • the male contacts 58 supported by module 24 extend through openings 64 in a contact restraining web 68 in a manner comparable to the female connector shown in Figures 2, 3 and 5.
  • termination portions such as 32" and 52" of contacts 32 and 58 may be readily modified to conform to any one or more of a variety of different conductor termination techniques without changing the configuration of the mating portions 32' and 58' of such contacts.
  • Dotted line 74 indicates that the insulation displacement portion of the contact termination end may be eliminated and substituted by a straight line extension of the material from which the contacts are made to provide direct printed circuit board mounting on the modular connectors.
  • dotted line 76 illustrates a solid conductor with a right angle bend which may be used in connection with a right angle printed circuit board mounting assembly.
  • Such extensions may also be formed so as to have a rectangular cross-section to permit wrap termination of wire conductors to the contacts and module.
  • FIG 8 illustrates a preferred form of the present invention wherein the contact supporting module termination face is adapted for terminating and providing str d in relief to a flat multiconductor cable.
  • the termination end of each contact 77 held by the molded plastic contact support module 78 is formed to provide a typical insulation displacement type flat cable conductor connection "V" or notch 81.
  • V insulation displacement type flat cable conductor connection
  • the module 78 may be of either male or female contact configuration for nesting within either a receptacle or plug outer housing element such as 14 or 22 as described hereinbefore.
  • the flat cable insulation displacement termination ends 81 are formed on the conductor termination portion of contacts such as 32 and 58 respectively in lieu of a singlesolid wire or stranded wire insulation displacement portion as illustrated in Figure 4 at 56.
  • the plastic insert module 78 is provided with two upright pressure plate and cable strain relief support locking members 82.
  • Cable pressure pTate 86 in turn is provided with two downwardly extending latch member 88 carrying latch hooks 91. After the cable has been put into place upon the top surface of the module 78 the pressure plate 86 is forced down over the cable with the latch hooks 91 engaging the lowermost surface 94 of each locking member 82 or the module 78.
  • the pressure plate 86 is preferably made of a material which has sufficient elasticity such that the latch members 88 are forced away from one another out over bosses 96 on the end surfaces of locking members 82 to permit the latch hooks 91 to engage the lower surfaces 94 of the locking members or module.
  • Strain relief clamp 100 is preferably made of a spring metal material.
