Abstract

An electrical tab receptacle for mating with a complementary tab is provided with an integral tongue having a lance whereby the receptacle can be releasably secured to the tab, the tongue being resiliently depressible by means of a finger, a tool, or part of a housing containing the receptacle, to release the receptacle from the tongue.

Description

The invention relates to an electrical tab receptacle.
Receptacles of this general description are well-known in various forms, for example as described in U.K. Patent Specification Nos. 777,677 and 793,654.
Such receptacles may be releasably engaged with a complementary tab in an exposed arrangement, or may be mounted in an insulating housing either singly, or as a group for simultaneous connection to a plurality of complementary tabs.
Such tab and receptacle connectors have in the past fifteen years formed the principal means of connecting harness wiring in consumer goods and the automotive industry.
In more recent years there has been an increasing demand for increased reliability of electrical connectors due to high maintenance and warranty liabilities of consumer goods and automotive manufacturers. There is thus a demand for a tab receptacle which can be used in the conventional manner but which is less susceptible to inadvertent disconnection from a complementary tab due, for example, to vibration or mishandling, but which can nevertheless be easily disconnected when required.
An electrical tab receptacle according to the invention is formed from sheet metal and comprises a generally channel-shaped receptacle portion having a base and upstanding side walls with free edge portions of the side walls turned in over the base for receiving a complementary tab between the base and the turned in edges of the side walls and an integral tongue extending from the base at the forward, tab entry end of the receptacle portion, the tongue extending rearwardly in inclined manner towards the turned-in edges of the side walls, the free end of the tongue at the rearward end of the receptacle portion projecting externally beyond the turned-in edges of the side walls, and the tongue within the receptacle portion being formed in a middle portion with a lance inclined rearwardly from the tongue towards the turned in edges of the side walls and arranged and adapted to engage a corresponding recess or aperture in a complementary tab when mated with the receptacle for latching the tab against withdrawal from the receptacle.
In a preferred embodiment the base of the receptacle portion is formed with a pair of longitudinal slots, one on each side of the tongue, from which slots the metal is turned up to present edges opposed to respective turned-in free edge portions of the side walls, a complementary tab mated with the receptacle being received between these opposed edges and the edges of the turned-in free edge portions of the side walls.
With the receptacle of the invention, the tongue constitutes a readily accessible release member for actuation by a finger or tool, depression of the tongue towards the base effecting release of the tongue lance from the tab aperture to allow withdrawal of the tab from the receptacle.
The invention will now be described by way of example with reference to the drawings, in which:
FIG. 1 is a perspective view of the receptacle portion of an electrical tab receptacle according to the invention;
FIG. 2 is a front end view from the left of FIG. 1;
FIG. 3 is a fragmentary side view of the receptacle of FIGS. 1 and 2 mated with a complementary tab;
FIG. 4 is a fragmentary sectional view of the receptacle of FIGS. 1 and 2 in a first form of insulating housing; and
FIG. 5 is a fragmentary sectional side view of a modified form of the receptacle of FIGS. 1 and 2 in a second form of insulating housing.
The receptacle of FIG. 1 may be formed at its right-hand end with a wire connecting portion such as a crimping ferrule of known form, not shown.
The receptacle portion of the receptacle is formed of sheet metal and is generally channel-shaped having a base 1, and upstanding side walls 2. Free edge portions 3 of the side walls 2 are turned in over the base 1 and are formed with elongate slots 3a, extending into the side walls 2 to increase the flexibility of the turned-in edge portions 3.
A tongue 4, integral with the forward end of the base 1 is turned back between the side walls 2 to extend rearwardly in inclined manner towards the turned-in edge portions 3 of the side walls 2. The tongue 4 extends beyond the rearward ends of the turned in edge portions 3, and is then turned outwards generally perpendicular to the base 1 to project externally of the receptacle portion to form a release member 5. The tongue 4 is formed in a middle portion with a pushed-up lance 6 inclined rearwardly towards the turned in edge portions 3 to present a latch for releasably engaging a complementary tab aperture as shown in and to be described with reference to FIG. 3.
Forward ends 7 of the turned in edge portions 3 are chamfered in rearwardly inclined manner towards the base 1 to facilitate tab entry. The base 1 is formed with a pair of longitudinal slots 8, one on each side of the tongue 4, and extending into the side walls 2. The metal from the slots 8 is pushed up from the base 1 to present upstanding flanges 9 with edges 10 opposed to the turned in edge portions 3.
In use, as shown in FIG. 3, a flat tab 11 having an aperture 12 is inserted into the forward end of the receptacle, between the turned in edge portions 3 and the flange edges 10. The tab 11 depresses the tongue 4 towards the base 1, and flexes the turned in edge portions 3 to clamp the tab 11 between the edge portions 3 and the edges 10. The latch lance 6 is received in the tab aperture 12 to resist withdrawal of the tab 11 from the FIG. 3 condition. Depression of the release member 5 towards the base 1 disengages the lance 6 from the aperture 12 to permit withdrawal of the tab 11 from the receptacle.
The receptacle is suitably mounted in an insulating housing 17 formed of resilient insulating material such as Nylon, as shown in FIGS. 4 and 5.
In the arrangement shown in FIG. 4 a lance 13 is pushed out from the base 1 of the receptacle below the tongue 4 to extend in rearwardly and outwardly inclined manner, which lance 13 engages a shoulder 14 in the base 18 of the housing 17 in known manner.
The housing 17 is formed in its upper wall 20 with a recess 15 into which the release member 5 of the receptacle freely projects. A flexible cover portion 16 extends over the recess 15, and manual pressure on the cover portion 16 serves to flex the cover portion 16 inwardly to engage and depress the release member 5 to release a tab mated with the receptacle, as described with reference to FIG. 3.
The forward end (left-hand end in FIG. 4) of the upper wall 20 of the housing 17 is formed with a depending wall 19 which serves to prevent insertion of a tab between the upper wall 20 of the housing 17 and the receptacle, and also serves to limit axial movement of the receptacle forwardly of the housing 17. Axial movement of the receptacle rearwardly of the housing 17 is limited by the engagement between the lance 13 and the housing shoulder 14. The receptacle is thus secured within the housing.
In the arrangement shown in FIG. 5, the base 1 of the receptacle is formed with a hole 21 in which there is received a boss 22 on the base 18 of the housing 17, the relative sizes of the hole 21 and boss 22 being such that the receptacle is capable of limited movement axially relative to the housing 17.
To allow for this movement of the receptacle the depending wall 19 of the housing of FIG. 4 is omitted, and insertion of a tab between the upper wall 20 of the housing 17 and the receptacle is prevented by a longitudinal rib 23 formed centrally on the upper wall 20 of the housing 17 and extending downwardly between the turned in edge portion 3 of the receptacle, in known manner.
The upper wall 20 of the housing 17 is formed with a sloping surface 24 directed towards the release member 5, and positioned relative thereto such that forward axial movement of the receptacle relative to the housing 17 causes the release member 5 to engage the sloping surface 24 and be depressed thereby to release a tab mated with the receptacle, as described with reference to FIG. 3.
The arrangement of FIG. 5 is particularly advantageous since with a wire connected to the receptacle and a tab mated therewith, a tensile force applied to the wire in the direction away from the tab will not disconnect the receptacle from the tab since the force will not cause relative axial movement between the receptacle and its housing, but the receptacle can simply and easily be disconnected from the tab by pulling the receptacle housing in the direction away from the tab. When this is done the housing moves axially relative to the receptacle because movement of the receptacle is prevented by its engagement with the tab by way of the lance 6, and thus the sloping surface 24 of the housing 17 will engage the release member 5 and releases the receptacle from the tab. The receptacle remains secured in its housing by the engagement of the boss 22 of the housing in the hole 21 in the base 1 of the receptacle.
Although the arrangements described above comprise only a single receptacle and associated housing, it will be appreciated that a single housing can, in known manner, being formed to receive a plurality of individual receptacles. Clearly the latching feature provided by the tongue of the receptacle of the invention need be provided for only one of the receptacles in the housing, and thus the other receptacles can be conventional ones, and the housing need be provided only with means, such as the flexible cover portion of FIG. 4 or the sloping surface of FIG. 5, to release the tongue of the one receptacle. Otherwise all the receptacles can be in accordance with the invention and the housing be provided with corresponding multiple tongue release means.
