Description
- This invention relates to an electrical tab receptacle having a latch adapted positively to lock in an aperture in the tab to resist inadvertent separation of the tab and receptacle.
- In our US Patents 3,976,348 and Re. 30,277, we have disclosed an electrical tab receptacle formed from sheet metal with a box-like body of generally rectangular section and open at an end, and including a pair of spring arms opposed to a single spring arm to define between them a tab receiving space, a latch projection being formed centrally on one of the single spring arms and presenting a rear-facing shoulder in the tab receiving space arranged to engage a recess or aperture in a tab when received between the opposed spring arms to resist tab withdrawal.
- The tongue extends within the body with a free end projecting externally of a rear end of the body, and the shoulder being within the body. In such arrangement the receptacle may be disengaged from the tab by depressing the exposed free end of the tongue, and in one embodiment the receptacle is contained within a housing capable of limited relative movement to the receptacle whereby a pull on the housing will actuate the housing to depress the free end of the tongue.
- Tab receptacles of this kind have met with substantial commercial success, particularly in automotive applications, where the integrity of the electrical circuitry has been substantially improved. However, the use of such receptacles is limited to connectors having relatively few receptacles, and in which the alignment between the tabs and receptacles is relatively precise.
- It is an object of the invention to obtain the advantageous positive locking feature in receptacles having a wider application and capable of providing low frictional forces on engagement and disengagement such that they can conveniently be employed in multi-way connectors.
- According to the present invention, there is provided an electrical tab receptacle as defined above in the second paragraph which is characterised in that the spring arms extend forwardly cantilever fashion from a-pair of opposite sides of the body at that end, the spring arms converging forwardly and an end of at least one arm being bent outwardly to define a divergent entrance to the tab-receiving space, the single spring arm being of width corresponding to the overall width of the pair of spring arms and being formed with an aperture extending rearwardly of the latch projection to the body.
- The electrical tab receptacle according to the invention is capable of wide application and of providing low frictional forces on engagement and disengagement when compared with the prior electrical tab receptacle, the provision of the aperture in the single spring arm assisting in balancing the spring forces between the spring arms.
- Suitably, the latch projection formed on the single spring arm has an outwardly bent end portion and, preferably, all of the arms have outwardly bent end portions to facilitate tab entry.
- The bent out end portion of the spring arm having the latch projection suitably provides a release member for disengaging the latch. The receptacle may be mounted in a housing adapted for limited movement relative to the receptacle and formed with a projection arranged to engage the bent out end portion of the latch spring arm on relative rearward movement to effect release.
- The box-like body is suitably of open-seam form, the seam extending between ends at one side, and between individual arms of the pair of arms.
- The invention will now be described, by way of example, with reference to the accompanying drawings, in which:
- Figure 1 is a fragmentary exploded view of a multi-way connector according to the invention; and
- Figure 2 is a fragmentary sectional view of part of the connector of Figure 1.
- A multi-way connector housing 1 has a plurality of cavities for tab receptacles 2. Each receptacle 2 comprises a box-like body 3 having an open seam 4 and at a rear end being integrally formed with a crimping portion secured to a conductor wire. The body 3 is formed on the side opposite the seam 4 with a
latch 5 for releasably securing the receptacle in the housing by engagement with a forward facingshoulder 6. At the forward end, the body 3 is formed at the seam side with a pair ofspring arms 7, and at the opposite side with a single,wider spring arm 8, thespring arms forward ends forward end 10 of thewider arm 8 is adapted to engage a projection 11 at the forward end of the housing cavity, the projection having aninclined surface 12 adapted, on rearward movement relative to the receptacle 2, to engage theforward end 10, and cam thespring arm 8 outwards. - The
wider spring arm 8 is formed with alatch 13, forwardly of anaperture 14, and presenting a rear facingshoulder 15 adapted to engage anaperture 16 formed in thecomplementary tab 17. Theaperture 14 extends rearwardly towards the body 3, opposite the seam 4, and serves substantially to balance the spring characteristics ofspring arm 8 in relation to thearms 7. - The receptacle 2 is assembled into the housing with a
rib 18 of the housing 1 engaging the body seam 4, thelatch 5 engagingshoulder 6 and positioned in a forwardly extendinghousing slot 19.Shoulders 20 at opposite sides of the forward end of the receptacle body 3 are spaced rearwardly ofhousing shoulders 21, whereby relative movement of the housing 1 rearwardly of the receptacle 2 is possible in order to engage thehousing projections 12 with thespring ends 10 for release of thelatch projections 13 from thetab apertures 16 by cam action as has been described.
