Definitions

  • This invention relates to electrical connectors and more particularly to an electrical connector assembly for releasably interconnecting electrical circuits through a fuse.
  • Customarily electrical circuitry is connected through fuses so that in the event of electrical overload exceeding the capacity of the fuse, the fuse opens the circuit and prevents damage to the circuit components.
  • cartridge fuses are employed, a cartridge fuse comprising a short tubular component of standard length and diameter incorporating an insulating sleeve, usually of glass, contains a fuse wire core connected at its ends to metal end-caps to the sleeve.
  • the fuse is generally mounted in a connector with each end-cap in a receptacle and each receptacle is then connected to one or more circuit leads. Opening of the circuit containing the fuse requires removal of the fuse and caps from the receptacles.
  • a connector according to the invention comprises a bipartite insulating housing, a first part releasably mating with a second part and the first part containing spaced fuse cap receptacles for receiving respective end-caps of a cartridge fuse, the second part carrying at least one tab contact arranged so that on mating engagement of the two housings the tab contact is arranged to engage an end of an end-cap of the fuse.
  • the second part of the housing is formed with a pair of spaced tab contacts arranged for engaging the fuse end-caps at respective ends of the fuse.
  • Means may be provided for arranging second tab contacts in back-toback relationship with respect to the first mentioned tab contacts to effect multiple connections at each end of the fuse.
  • Another object is to provide an electrical connector assembly in which the first housing part contains fuse receptacles for receiving end-caps of a cartridge fuse.
  • Still another object is to provide an electrical connector assembly in which the second housing part carries at least one tab contact.
  • FIGURE 1 is a sectional elevation of a bipartite electrical connector assembly
  • FIGURE 2 is a transverse section of the electrical connector assembly taken on the line 22 of FIGURE 1.
  • the connector assembly comprises first and seconr matable housing parts 1 and 2 of resilient insulatin material.
  • the housing part 1 contains spaced pairs 0. tab terminals 3 which project into a recess 4 of the hous ing part 1 to define fuse end-cap receptacles, each pair 0: tabs 3 receiving an end-cap 11 of a cartridge fuse 5 therebetween.
  • Each ta-b terminal 3 is crimped at its rear end to a conductor Wire 3a extending externally of the housing part 1 and forwardly of the crimp section is formed with a pair of pushed-out tongues 6 projecting on the same side of the tab and engaging a rear facing shoulder 1a of the housing part, as seen in FIGURE 2.
  • Each tab terminal 3 is formed forwardly of the tongues 6 with a rearwardly and sidewardly-inclined detent tongue 7 projecting on the same side as the tongues 6 and centrally disposed between them. The tongue 7 is pushed out from a slot in the tab to engage a forward facing shoulder 1b of the housing part 1 to latch the tab terminal in a slot 8 formed in the housing part and opening to a base of the recess 4.
  • the tab terminal 3 projects forwardly of the detent tongue 7 as a flat rectangular tongue of reduced width formed at its forward extremity with a central dimple-like indentation 9. As seen most clearly in FIGURE 2, the dimples 9 of the tabs 3 of each pair being opposed in convex manner towards each other.
  • the housing part 1 is formed with projections 10 presenting, as seen in FIGURE 2, arcuate concave recesses for cradling respective end-caps 11 of the fuse 5.
  • Each fuse end-cap 11 is resiliently gripped between the forwardly projecting parts of the tab terminals 3 within the recess 4 beyond the dimples 9, as seen in FIG- URE 2, which clamp the end-caps 11 in the cradle portions of the projections 10.
  • the recess 4 of housing part 1 is defined within a forwardly extending wall 12 defining a protective shroud for the projecting tab portions within the recess, and the wall has side parts 13 closely spaced from the ends of the fuse end-caps 11 to define narrow slots 14 between the end-caps 11 and the wall parts 13. Forward inner side portions of wall parts 13 are outwardly chamfered at 13' to provide lead-in surfaces as described below.
  • the housing part 1 is provided rearwardly of the wall 12 with a pair of forwardly extending external resilient latch arms 15 integrally formed with the housing part 1 and projecting at their forward ends to engage strap portions 16 of housing part 2 releasably to latch the two housing parts together.
  • the housing part 2 has a forward shroud portion 17 slidably embracing the wall portion 12- of part 1 in telescopic manner and at its forward end abutting a stop 18 of housing part 1 to limit relative movement of the housing parts 1 and 2 together.
  • Slots 19 are formed in housing part 2 which open within the shroud 17 opposite to re spective slots 14 defined between the fuse end-caps 11 and the wall parts 13 of housing part '1.
  • Each slot 19 is formed with an inner forward shoulder 20 and an outer rearward shoulder 21 which are forward facing and are associated with corresponding rear facing shoulders 22 and 23 spaced rearwardly. Rearwardly of shoulders 22 and 23, the slots 19 are widened on opposite sides to accommodate conductor wires 24, 25 extending rearwardly outside housing part 2.
  • the conductor wires 24, 25 are crimped at their forward ends to respective tabs 26 of identical form to the tabs 3 mounted in housing part 1. Identical reference numerals are applied to parts of tabs 26 corresponding to similar parts of tabs 3.
  • a pair of tabs 26 are arranged in backto-back fashion with the dimples 9 and detent tongues 7 on remote sides, as seen in FIGURE 1.
  • the detent ongues 7 and ears 6 engage respective shoulders 20, 21, md 22, 23 to latch the tabs 26 in the slots 19 and, in view of the rearward staggering of shoulders 21, 23 compared with inner shoulders 20, 22, the inner tab 26 projects further forward than the outer tab 26.
  • the portion of the inner tab projecting forwardly of the outer tab 26 is disposed within the complementary slot 14 with the dimple 9 engaging the end of the fuse end-cap 11 and the tab is resiliently gripped between the adjacent wall part 13 of wall 12 housing part 1 and the end of the fuse endcap 11 in a wedge fit.
  • the chamfered surfaces 13 act as guide surfaces directing forward ends of the inner tabs 26 into the slots 14 and towards the ends of the fuse end-caps 11, and furthermore may engage forward ends of the dimples 9 of the outer tabs 26 to clamp the outer tabs tightly against the inner tabs.
  • pairs of tabs 26 are provided at positions corresponding to opposite ends of each cartridge fuse in the manner shown in FIGURE 1, but outer tabs 26 of each pair may be omitted if desired.
  • the housing part 1 is formed with sidewardly projecting flanges 30 formed with apertures 31 arranged so that the housing part 1 may be disposed in a bulkhead aperture and secured to the bulkhead by fasteners extending through apertures 31 into the bulkhead.
  • An electrical fuse connector assembly comprising a bipartite insulating housing having a first housing member releasably connected with a second housing member, the first housing member having mounted therein spaced fuse receptacles for receiving end-caps of a cartridge fuse and the said second housing member having mounted therein at least one tab contact member so that upon mating engagement of the first and second housing members, the tab contact engages an end-cap of the fuse, the tab contact being disposed in a slot in the second housing member and arranged to wedgingly engage an end of the fuse endcap in a slot defined between the end portion of the endcap and an adjacent wall of the first housing member.
