DESCRIPTION OF THE PREFERRED EMBODIMENT
The male connector element, generally designated 10, is constructed in two half-shell portions 12 and 14, as can be seen from Fig. 2. Each of the conductor terminations o~ the conductor element consists of two jaw portions 16 and 18. The jaw portion 16 has two projections 20 and 22 and a recess 24 therebetween while the jaw portion 18 has two recesses 26 and 28 and a projection 30. The jaw portions are formed of flat 10~5~30 R. W. Donnelly et al. 11-5 metal, e.g. brass strip, and may be inexpensively produced by stamping from sheet stock. The jaw portions 16 are located in parallel slots 32 in the inner surface of half-shell portion 12 and the jaw portions 18 are located in parallel slots 34 in the inner surface of half-shell portion 14.
The upper half-shell 12 has a row of recesses such as 36 and the lower half-shell 14 has a row of up-standing pillars such as 38, each of which is aligned with one of the recesses 36.
In addition, the lower half-shell has two up-standing studs 40 (only one being visible in Fig. 2), each of which is aligned with a hole (not shown) in the upper half-shell. These pillars, studs, recesses, and holes are used to locate the two half-shells with respect to each other.
Each of the jaw portions 18 has an extension 42 which extends through an extended slot 44 in the body of the half-shell 14. The end of this extension is twisted 90~, as can be seen in Fig. 2, so as to be normal to the plane of the flat strip.
The half-shell portions 14 and 16 have cavities 46 and 48 in their inner surfaces at their left-hand ends as viewed in Fig. 2.
When the two half-shell portions are fitted together, the two cavities define a "tunnel" of rectangular cross-section within which there is a row of extensions 42, each of which (as will be seen) forms a male contact element. The edges 50 of the "tunnel" are bevelled, as can be seen from Fig. 3, to facilitate mating with a female connector element.
To terminate a flat cable, such a cable 52 is fitted to the lower half-shell 14 after the latter has had its jaw portions 18 installed, and then the upper half-shell 12 is fitted to the lower half-shell. The two half-shells are then squeezed together, for instance in a press tool or by a hand R. W. Donnelly et al. 11-5 lO~S~30 tool. This causes each strip conductor of the flat cable to be gripped between two jaw portions 16 and 18, and the insulation thereof to be ruptured to establish a good electrical connection as described in the aforementioned Saunders patent. This is facilitated by the serrations 54 on the lower jaw portion 18.
The two half-shells are then held together by an interference fit between the pillars 38 and projections 40 with the corresponding parts of the upper jaw member 12. This can be assisted by any suitable means, such as a glue, ox ultrasonic welding, or possibly by screws (as shown at 38).
The male connection element 10 also has two latches 56, 58 for latching it to the female element, as will be described below.
Now we consider the female connector element 60, Figs. 4, 5, and 6, which is similar in many respects to the male element 10.
Thus, only the differences will be described. The first to consider is the lower jaw element 18a, Fig. 6. This is the same as the corresponding element 18, Fig. 2, in its flat conductor contacting portion, but its extension 42A is bifurcated to form a female electrical contact suitable to cooperate ~ith the male contact 42 of Fig. 2. The bifurcated extension lies in the same plane as the flat strip portion of jaw 18a~ The jaw por-tions 16a, 18a can be produced by stamplng from flat sheet stoc~.
The left-hand portions of the connector element half-shells 12a, 14a together form a shroud 62 for the bifurcated female contacts, with a front wall 64 having a hole 66 aligned with each female contact.
The next important difference is that instead of rockable latches, as in the male element, the female element 60 has hooks 68, 70, Figs. 4 and 5, for cooperation with the latches.
_7_ 10~5430 R. W. Donnelly et al. 11-5 The connector element 60 terminates a flat cable 52a in the same manner that connector element 10 terminates flat cable 52.
When the two elements are to be fitted together, the shroud 62 of the female element 60 is fitted into the "tunnel"
of the male element 10, such that each male contact 42 enters one of the holes 66 in the shroud and thus engages with a female contact 42a. When the elements are fully mated, the latches 56, 58 on the male element engage with the hooks 68, 70 on the female element to hold the male and female elements together. To insure that the elements mate the right way up, the dimensions between the hooks and the connector body at the two ends thereof differ, as do the dimensions between the latches and the connector body. This can be seen clearly from the drawings, especially from Fig. 7. In addition, as can be seen from Figs.
3 and 4, bevels 50, 50a have been added to insure that polarization is correctly attained. When the connector elements are mated, they electrically connect the conductive tracks on the flat cables 52, 52a.
Each latch, Fig~ 8, has an extension 72, which fits into a hole 74 in the lower half-shell 14.
It is to be understood that the foregoing description of specific examples of this invention is made by way of example only, and is not to be considered as a limitation on its scope~
