Definitions

  • This invention relates to electrical connectors, particularly but not exclusively, electrical connectors for making electrical connection to electromagnetic relays and similar electrical devices where a body of the device has a plurality of parallel blade terminals extending from one face thereof.
  • a connector comprising a block-like moulded synthetic resin body having therein, parallel passages within which socket terminals are housed.
  • the socket terminals each include a locking lance which co-operates with an abutment on the wall of its respective passage to resist withdrawal of the socket terminal from its passage in one direction, the terminal and passage having abutting surfaces locating the terminal in the passage against movement in the direction opposite the withdrawal direction.
  • a connector includes a moulded synthetic resin body, a plurality of parallel terminal receiving passages in the body, said passages being open at one face of the body to permit insertion of the terminals into the passages and having abutment surfaces to limit movement of the terminals in the passages in the insertion direction, each of said passages having a shoulder intermediate the ends thereof for engagement by a locking latch of the terminal to resist withdrawal of the terminal, and each passage being open at an opposite face of the body to provide access to said terminals whereby mating terminals can be introduced into said terminals in use, the body having a plurality of locking bar passages extending into said body parallel to said terminal receiving passages, each locking bar passage being positioned adjacent a respective terminal receiving passage, and the connector including a plurality of locking bars for insertion into respective locking bar passages, the arrangement of the locking bars and the body being such that during insertion of the locking bars co-action of each locking bar and the body generates a movement of part of the body and/or the locking bar in a direction transverse to
  • each terminal receiving passage includes a flexible resilient region adjacent the respective locking bar passage, said region being moved, by insertion of the respective locking bar, transversely from'a rest position clear of the terminal of the respective terminal receiving passage, to a locking position in which the region engages the terminal to resist withdrawal of the terminal from its passage.
  • each locking bar passage and its respective terminal receiving passage communicate such that upon insertion of the respective locking bar a portion of the locking bar is deflected transversely to engage the respective terminal to resist withdrawal of the terminal from its passage.
  • said locking bars are carried by a locking plate which engages said opposite face of the body, said locking plate having apertures therein to provide access to said terminal receiving passages.
  • said locking plate and locking bars are parts of a common component.
  • said locking plate is engaged as a snap fit with said body.
  • said locking plate includes mounting means whereby the assembly of the plate and body may be mounted on a support structure.
  • a plurality of locking plates and respective bars are formed as parts of a common unit to which a plurality of respective connector bodies are coupled.
  • the locking plate constitutes a mask for the connector body whereby common connector bodies can be used in different applications, the connector bodies having terminal receiving and locking bar passages to suit a variety of applications and the locking plate having apertures associated with only those terminal receiving-passages which are to be used for a particular application.
  • the connector includes a moulded synthetic resin connector body 11 of block-like form and a terminal locking member 12 also formed as a synthetic resin moulding.
  • the connector body 11 is generally cubic including a pair of opposite faces 13, 14 which, hereinafter will be referred to as the upper and lower faces respectively. Extending within the body 11 and open at both upper and lower faces 13, 14 are nine, parallel, terminal receiving passages 15-23, the passages 15-19 being of larger width than the remaining passages 20-23 since they are intended to receive larger terminals than the passages 20-23.
  • the terminals to be engaged in each of the passages are of the same general type in the sense that they receive mating blade connectors and are shown in broken lines in Figure 3.
  • each terminal 24 of the passages 15-19 is a flat socket terminal of the kind known as a LUCAR (Registered Trade Mark) including a socket portion at one end and a lead connecting portion at the opposite end.
  • LUCAR Registered Trade Mark
  • Each terminal of the passages 20-23 is smaller and -includes a socket portion having curved fingers which grip the blade, and a lead connecting portion.
  • the lead connecting portion of each of the terminals 24 will, in use, be crimped around a respective conductive lead or leads to achieve electrical connection between the terminal and the core of the lead.
  • each of the passages 15-23 is open to permit insertion of the respective terminals 24 from the lower face 14 of the body.
  • the terminals are inserted socket end first, and the upper face ends of the passages 15-23 are partially closed thus defining internal abutments limiting the insertion movement of the terminals 24.
  • the upper face ends of the passages are not completely closed since access must be provided to the terminals 24 so that mating blade terminals 25 -(shown in broken lines in Figure 3) of the device to which connection is to be made, can be introduced into the socket terminals.
  • each passage wall is formed with a shoulder 26 facing towards the abutments at the upper face ends of the passages, and against which a locking lance 27 of each terminal 24 can abut.
  • the locking lances 27 are of conventional form, and the arrangement is such that as each terminal 24 is inserted into its respective passage the locking lance 27 thereof is deflected inwardly, and, when the terminal is correctly positioned within its passage the free end of the lance 27 aligns with the respective shoulder 26 and can spring outwardly to lock behind the shoulder 26 and thus resist withdrawal of the terminal from the passage.
  • the body 11 is formed with a further plurality of passages 28-36 (indicated by cross-hatching in Figure 8) arranged to receive locking bars of the locking member 12.
  • the passages 28-36 extend parallel to the passages 15-23 and each of the passages 28-36 is positioned adjacent a respective one of the passages 15-23.
  • a region of the wall which separates each passage 15-23 from its respective passage 28-36 is shaped to define a flexible resilient arm 37.
  • the arms 37 extend lengthwise of the passages and are disposed in the lower halves of their passages. Each arm 37 extends upwardly from the lower face region of the respective passages and has its free end adjacent the transverse central plane of the body.
  • the inherent resilience of the arms 37 urges the arms 37 to a rest position in which they are aligned with the length of their respective passages.
  • the arms can however be flexed in such a manner that they are inclined into their respective passages 15-23, so that their free ends occupy a position beneath the socket portions of their respective terminals 24.
  • the locking member 12 comprises a synthetic resin moulding in the form of a generally rectangular locking plate 41 from one face of which project nine parallel locking bars 42.
  • the locking bars 42 are integral with the plate 41 and are arranged in the same pattern as the locking bar passages 28-36 of the body.
  • the cross- sectional shape of each of the locking bars 42 corresponds to that of its respective locking bar passage 28-36 except that at its free end each of the locking bars 42 is tapered to define a ramp surface 43 on one face thereof.
  • the locking member 12 After introduction of the terminals 24 into the passages 15-23 the locking member 12 is engaged with the body 11 by inserting the locking bars 42 into the passages 28-36 from the upper face end of the passages 28-36. As the locking bars 42 are pushed simultaneously into their passages 28-36 the ramp surfaces 43 of the locking bars 42 co-act with the arms 37, and deflect the arms 37 from their rest positions to their operative positions so that the free ends of the arms 37 lock beneath the socket portions of the terminals 24. When the bars 42 are fully inserted into their passages 28-36 the undersurface of the plate 41 abuts the upper face 13 of the body 11. In order to provide access to the terminals 24 the plate 41 of the member 12 is provided with appropriately positioned apertures 44.
  • the apertures 44 are tapered from a maximum width at their outer end to provide a lead-in to guide blade terminals of the device to which connection is to be made into the passages 15-23 to mate with the socket portions of the terminals 24.
  • the plate 41 Adjacent its four corners the plate 41 is provided with four integral flexible legs 45 two of which extend down one side face of the body 11 and the other two of which extend down the opposite side face of the body 11 when the member 12 is fully engaged with the body 11.
  • Each of the legs 45 is formed with an aperture within which a respective lug 46 on the sides of the body 11 is received.
  • the lugs 46 include a ramp surface on one end which deflects the respective leg 45 as the member 12 is engaged with the body 11, the legs 45 then springing back to their original configuration to embrace the lugs 46 within the apertures of the legs 45 when the full engagement position of the member 12 on the body 11 is reached.
  • the ramp surfaces 43 of the bars 42 are replaced by equivalent ramp surfaces on the arms 37 or both the arms 37 and the bars 42 are provided with co-acting ramp surfaces.
  • each passage 15-23 communicates with its respective passage 28-36 in such a manner that a locking shoulder provided on each locking bar 42 can engage beneath the socket portion of the respective terminal 24.
  • the locking bars are deflected transversley by ramps on the body and/or bars, from their straight configuration so that when fully engaged with the body 11 the locking shoulders of the bars engage with the terminals to resist withdrawal. It will be recognised that in each alternative construction the lengthwise movement of the locking bars results, by virtue of a cam action, in transverse movement of a part of the body or of the locking bar to engage the respective terminal.
  • the plate 41 Since the plate 41 has apertures 44 through which the terminals 25 pass to mate with the terminals 24 then the plate 41 can be used as a mask permitting access only to desired passages 15-23. It follows from this that a common body moulding can be produced having passages to suit a wide variety of different applications, and each body 11- will then be engaged with a specific locking member 12, the plate 41 of which will contain only those apertures which are related to the application for which the connector is intended.
  • a plurality of locking members can be provided as parts of a common moulding to which a number of bodies 11 can be attached.
  • a single connector unit can be provided for a number of electrical devices and moreover each separate locking member 12, or a multiple locking member can carry mounting lugs or brackets whereby the connector can be secured to, for example a vehicle bulkhead.
  • Figure 9 illustrates diagrammatically the base of a conventional electromagnetic relay wherein the five blade terminals 25a shown in solid lines represent the conventional terminal layout.
  • the four terminals 25b shown in dotted lines are indicative of additional terminals one or more of which may be provided where the relay fulfils other functions.
  • the terminals 24 of the passages 20-23 are narrower and shorter in their socket portion than are the terminals 24 of the passages 15-19. This dimensional difference is easily accommodated in the locking action of the bars 42 by appropriate choice of length for the relevant bars 42.
  • the terminals 24 will be retained in their respective passages 15-23 by their lances 27 and the shoulders 26 prior to engagement of the locking member 12.
  • the lances 27 are not adequate .to protect the terminals against being pushed from their passages 15-23 in the withdrawal direction when a terminal 25 is mated therewith.
  • the arms 37 in conjunction with the locking bars 42 or parts of the bars 42 themselves constitute a more positive locking arrangement and have the added advantage that if the terminals 24 have not been inserted sufficient far into their passages then the locking member 12 will not be capable of being fully engaged with the body 11. It follows from this that the member 12 provides an immediate visual check that the terminals 24 are fully inserted into their respective passages. If it can be seen that the member 12 is fully engaged with the body 11, and is latched in place by the legs 45, then the operator is assured that the terminals 24 are fully home in their respective passages.
  • connectors described above is not restricted to making of connections to electromagnetic relays and relay variants, and clearly such connectors can be used with other electrical devices. Moreover, the use is not restricted to connectors having flat socket type terminals, although it is particularly advantageous with such terminals.
