Requested to 16 hr 30 October 1964 01 Mn to the O.A.M.P.I. (G.P. no. 50,525) by the financial anonymous said: company the stacks waving, residing in France.

Delivered 15 May 1966, published at Official ballot n° 4/5 of 1966. Priority: Patent application filed in France under the n° G.P. 919,860 27 December 1962 on behalf of the applicant.

Known couplers for the type called flat cells

of 4.5 volts, generally rectangular, which can exis -

tert in various sizes, and upper surface carrying

two tabs mounted asymmetrically and lengths

unequal.

These couplers provide contacts franc, a my -

strictly nonblocking and removal, and the ensuring of a branch -

telling a proper.

The present invention is a coupler of this type,

particularly simple and a very low cost.

To this end, a coupler according to the invention

essentially characterized in that it comprises a Receipt -

tackle sized to receive a flat and a

wafer, the latter traversed by two contacts overlying -

ceptibles rely on the blades of the stack, and the pro -

along the exterior of the receptacle, means being

provided to elastically press the wafer against

the stack.

In one embodiment particularly avanta -

geux of the invention, the means for pressing elastic -

telling the wafer against the stack are constituted by the

extensions contacts, in the form of two blades

arc compression strut against the corresponding wall of the récepta -

key before passing to the outside.

Preferably, the extensions of the contacts pass

outside by cutouts provided at corners of the

receptacle.

According to an improvement, these cut-outs are provided with

a shoulder overlapped by two tabs cut out

on the blades to ensure their strength.

According to a further improvement, there is a - LANs

listens for attached to part of the bottom of the receptacle and

extending outside.

Finally, according to a further improvement, the contacts

are formed by a flaring blades with a

spout can be collapsed to ensure the keeper on the PLA's -

quette.

The receptacle may include means for

its binding, mortise-or by screws or otherwise

with receptacles of the same type side by side, or face-to-face or back-to-back.

By designing is carried out and a coupler which, in addition to its simplicity and its very low cost, easy to place provides cells, couplings on the extensions easy external contacts, various fixtures in series or parallel, the use of stacks of different heights and excellent electrical contact scraping and non-flat.

The invention will be any case clearly understood by referring to the description which will follow, made opposite the attached drawing which shows one non-limiting example one embodiment of the invention and wherein:

Figure 1 shows a coupler in chain-dotted in elevation with a portion of a coupler neighbor;

Figure 2 is a cross-section of the coupler according to the line II-II of Figure 1;

Figure 3 is a side view of the coupler; and Figure 4 represents one of the contacts.

See individual drawing at a coupler according to the invention substantially consists of a receptacle of I, 2 consisting of a bottom and four walls 3, 4, 5 and 6 and by a wafer 7, all sized to contain, between the bottom 2, the walls 4, 5 and 6 and the wafer 7, a stack of the type called a 4.5 volts.

See that the walls are provided with tongues and grooves 8 and 9 which bring together several receptacles, as shown in chain-dotted in Figure 1. In addition, the base bears four holes not outlets 10 for links back to back by screw or rivet.

The wafer 7 carries two contacts 11 and 12 formed by the bent end of two blades 13 and 14 through-wafer by cutouts 15. Fitting the terminals on the wafer is ensured by a flaring 16 whose lower nose 17, after being folded to pass a portion of the cutout 18 inclined 15, is reset to the alignment of the flare. The blades then extend obliquely for arc buttress in 19 and 20 against the wall 3, after which it passes to the outside thereof by two lights corner 21.
