Definitions

  • a buzzer or bell may be mounted within the housing on the cup bottom and may be optionally connected in circuit by a special screw interlinking two of the tabs.
  • Our present invention relates to a connector of the plug-in type, particularly as used in telephone installations for temporarily connecting a multiconductor cord to an outgoing line terminating at a wall socket or other mating outlet.
  • the construction of such connectors varies in difierent parts of the world and may also be modified locally, as to the number of conductors used, to satisfy particular requirements.
  • the prongs of the male connector or plug may assume a variety of shapes, such as that of round pins or flat blades, and their relative positions are also not invariably the same.
  • a separate acoustic signal such as a bell or a buzzer, in the vicinity of a connector in response to an incoming call, as when the associated handset does not carry its own acoustic device.
  • Another object of our invention is to provide, in such connector, acoustic signaling means responding to incoming calls.
  • a plug-in connector designed to accomplish the aforestated objects, comprises a generally cup-shaped housing (usually of insulating mate rial) whose mouth is adapted to receive an insulating cover or insert serving as a carrier for an array of prongs designed to fit the jacks of a particular socket.
  • the prongs are conductively joined to respective tabs which, upon assembly of the housing and the insert, overlie respective conductor terminals within the housing, these terminals ice being individually connected to the several conductors of a telephone cord extending from an associated handset through an opening of the housing into the interior thereof.
  • the housing has several internal bosses with preferably threaded bores which are directed toward the mouth of the cup and, in the assembled condition, are aligned with respective holes of corresponding terminal members, perforations of respective tabs and apertures of the terminal carrier for passage therethrough of individual fasteners, such as screws, serving to join the carrier to the housing and at the same time to establish a conductive connection between the tabs and the respective terminal members, thereby also connecting the corresponding cord conductors to the associated prongs.
  • individual fasteners such as screws
  • the housing further accommodates an acoustic signaling device such as a buzzer which is preferably mounted directly on the bottom of the cup so as to transmit its sonicvibrations most effectively to the connector and through it to the surrounding atmosphere.
  • the energizing circuit of this signaling device includes at least one of the aforementioned tabs, rigid with an associated prong, as well as an additional and preferably resilient tab which has no prong of its own but can be brought into contact with the aforementioned rigid tab by a connector element such as a screw introduced through a further aperture in the terminal carrier.
  • a detent in the form of a spring-biased hook adapted to grip the face plate of the socket unless released by a pushbutton or other actuator accessible from the outside.
  • FIG. 1 is an exploded perspective view of the principal elements of a connector according to the invention
  • FIG. 2 is a fragmentary sectional view taken on the line IIII of FIG. 1 and showing the connector together with an associated socket plate;
  • FIG. 3 is a bottom view of an insert of terminal carrier forming part of the connector
  • FIG. 4 is a perspective view of a cover supplementing the parts shown in FIG. 1;
  • FIG. 5 is a cross-sectional view taken substantially on the line VV of FIG. 1.
  • the male connector or plug shown in the drawing comprises a generally cup-shaped housing 1 provided with a laterally extending neck 21 which forms an opening for a multiconductor telephone cord 22. Individual conductors 23 of that cord are clamped to respective terminal posts 3 rising from the bottom of the insulating housing 1.
  • An acoustic signaling device in the form of a buzzer 4, is rigid with the bottom of housing 1 which also accommodates an associated circuit element 5, such as a condenser shunting the electromagnet of the buzzer.
  • Screws 6 fit into the threaded bores of internal bosses 9 of the housing and pass through apertures 23 of an insulating terminal carrier 2 which is partly received in the mouth 24 of housing 1 as an insert or cover therefor and which has a neck 25 overlying the neck 21 of the housing to hold the cable 22 in position.
  • an insulating terminal carrier 2 which is partly received in the mouth 24 of housing 1 as an insert or cover therefor and which has a neck 25 overlying the neck 21 of the housing to hold the cable 22 in position.
  • four terminal members 10 Connected in circuit with the posts 3 and the terminals of buzzer 4 and condenser 5, via leads illustrated only in part, are four terminal members 10 having the shape of rings soldered onto the associated leads.
  • the screws 6 pass, in the assembled condition of the connector, through the apertures 23 of terminal carrier 2, the holes of conductor members and perforations 26 (FIG.
  • tabs 8a, 8b, 17 and 18 aligned therewith, these tabs being firmly clamped between the terminal members 10 and the bottom of carrier 2 when the screws are driven home in the associated bosses 9.
  • Three of the tabs, i.e. the tabs 8a, 8b and 18, are rigid metal strips joined to the inner extremities of respective prongs 7a, 7b and 7c projecting outwardly from carrier 2; this may be accomplished by notching and spreading the inner ends of the prongs, as best seen in FIG. 2.
  • Tab 17 is not so connected and is a resilient tongue spacedly overlying the tab 18 to which it may be mechanically and galvanically joined by a further screw 19 insertable through an aperture 20 of carrier 2; tabs 17 and 18 are provided, for this purpose, with aligned holes to receive the screw 19, the holes 27 of tab 18 being complementarily threaded.
  • a further aperture, not shown, may be provided on carrier 2 as a repository for screw 19 when the latter is not in use to interconnect the tabs 17 and 18.
  • Terminal carrier 2 is formed with a depression 28 to receive a lid 11 (best seen in FIG. 4) which has a cutout 29 to clear the prongs 7a, 7b and 7c and is provided with depending lugs 30 insertable with frictional fit into recesses 13 of carrier 2.
  • Pron'gs 7a, 7b and 7c are all shown as coplanar flat blades.
  • Prong 7b is undercut at 31 to provide clearance for a hook 14 rising from the terminal carrier 2 on which it is fulcrumed at 32 under pressure of a biasing spring 15.
  • This spring urges the book 14 into positive engagement with a face plate 33 (FIG. 2) of a mating socket one of whose jacks is designed to receive the prong 7b; since hook 14 is a blade coplanar with that prong and retractable within the undercut 31 thereof, its introduction into the socket through the corresponding slot 34 of plate 33 presents no problem.
  • a pushbutton 16 accessible from outside the housing 1 may be actuated, this button projecting through a side opening 35 of carrier 2.
  • a plug-in connector receivable in a socket for connecting a multiconductor cord of a telephone handset to an outside line comprising a generally cup-shaped housing with an opening for an associated multiconductor cord, a plurality of terminal members within said housing joined to respective conductors of said cord, said housing being provided with a plurality of internal bosses having bores directed toward the mouth of the cup, an insulating terminal carrier receivable on said mouth and provided with an array of outwardly projecting prongs engageable with respective jacks of an associated socket, said prongs terminating in conductive tabs on the side of said carrier facing the interior of said housing, said terminal members being receivable between said carrier and respective internal bosses of said housing and having holes engageable with the bores of said bosses, said tabs being formed with perforations and said carrier being provided with apertures in line with said perforations registering with the bores of said bosses, and a plurality of fasteners respectively insertable through said apertures and perforations and through
  • a conductor as defined in claim 2 wherein said energizing circuit further includes an additional tab on said carrier normally spaced from said one of said tabs and connector means engageable with said additional tab and said one of said tabs for conductively interlinking same.
  • said detent means comprises a hook projecting from said carrier alongside one of said prongs, the latter being provided with an undercut accommodating said hook.
