Description

Clip for fast connection of flat terminals The present invention

  a clip specifically designed for fast connection of flat terminals, which applies

  particularly in the field of household appliances.

  It often happens that the components of electrical appliances

  are equipped with flat terminals for connection to

  they are intended for. In some cases, it is

  necessary to perform a large number of functional connections

  between the terminals themselves, in addition to the

  connection connections to the different parts of the machine.

  This is the case, for example, of program control devices, selection, switches, etc., used in household appliances such as washing machines, dishwashers, dryers, electric stoves and the like. ' Currently, the most used form for making the two types of connections mentioned above, is to have double terminals at each connection tip, so that one of the terminals of each point can be used for connections to the connection. machine, while the other is intended for

functional connections.

  In other cases, where at each point there is no

  only one terminal is used for functional connections

  wire or tinned or cadmium-plated wire so that it

  It is also possible to connect the female terminals required

  for machine connections.

  Finally, there is also known a third system which consists in using staples or connecting bridges made of an electrically conductive material, which are introduced into the flat terminals and are anchored on

  these thanks to the force exerted by the elastic deformation

  that proper to which is subject the matter that constitutes them when they are connected to the terminals. These staples or bridges leave free a terminal length sufficient for it to be used, in turn, for the terminals

  The problem with the conventional technique is obvious.

  tooth. The first system, that which corresponds to doubling the connection terminals, assumes a considerable increase in the cost price as well as the space occupied, which, in

  many cases, is as important or more important than the price of

  comes from the device. The process of soldering the cables with tin is slow and labor-intensive,

and therefore it is expensive.

  The third system, which consists of using prefabricated bridges or staples, is the most appropriate and it is in his mind that the staple which constitutes the object of the

present invention.

  The known staples are constituted by a body shaped like

  flat blade with two windows or cut-outs

  mensions and position correspond to the terminals to be connected, and their main disadvantage is that it is necessary to pay particular attention when they are mounted on the terminals because these staples are not equipped with means of self- guiding and self-positioning which facilitate their introduction, and do not allow either

  make multiple connections between consecutive terminals.

  The clip for quick connection according to the invention provides a

  solution to this problem because it focuses automatically

  on the free ends of the terminals, allowing them to

fast and safe introduction.

  For this purpose it has been provided in the staples in question that the cut-outs formed therein, which are indispensable for being able to make their connection to the terminals, comprise in their extreme zones enlarged parts in the form of circular orifices, while on each side cutouts, and

  cooperation with the extreme orifices in question are defined

  of slightly trapezoidal shaped fins which are arranged with a slight inclination and which maintain a permanent pressure against the terminal, acting as a retainer of the clip and providing a connection

perfect electric.

  Also, the longitudinal edges of the staple are provided with a

  part bent which increases the rigidity of their structure.

  The clip can be provided with a single internal cutout. Lors-

  that it is not desired to bridge adjacent contiguous flat terminals, but on the contrary substantially distant, staples with a single cut-out are used to be connected by a wire, and therefore each of them has one of its edges two projections in the shape of a blade

  bent perpendicularly, intended to retain the conductive wire

self-folding.

  In other cases, that is to say when it comes to connecting two consecutive terminals or a larger number of consecutive terminals, the number of grooves that will be provided with the clip will coincide with the number of terminals, being provided in this case

  training between window cutouts of large size

  which will allow to see the numerical references of

terminals in question.

  Other features and advantages of the invention will be

  better understood by reading the following description

  of an exemplary embodiment and with reference to the accompanying drawings, in which: FIG. 1 represents a perspective view of a flat terminal fast connection clip made in accordance with the object of the present invention and provided for the purpose of connection

  electrical terminals separated from each other.

  FIG. 2 represents a cross-sectional detail of

  the staple shown in the previous figure after the auto-

  folding of its projections in the form of cable fixing blades

connection.

  Figure 3 shows, finally, a perspective detail of another clip provided, in this case, for the connection d; contiguous terminals, this clip being properly connected

to the corresponding terminals.

  In the figures mentioned above we can see that

  the clip for fast connection of flat terminals according to the invention

  tion is constituted by a blade-shaped body 1 provided with at least one transverse cutout 2 which, at each end, is

  widened by circular orifices 3 which allow an automatic

  perfect centering on the connection terminal 4.

  When the staple is intended to connect terminals distant from each other, as in the example shown in FIGS. 1 and 2, this staple comprises a single groove 2 and

  on each of its edges there are two flat projections 5 des-

  designed to be folded around the cable 6, as can be

  see it in the sectional detail of figure 2.

  In other cases, that is to say when both terminals

  number of two or more occupy positions in which

  tiguës, the blade-shaped body 1 has a length in

  agreement with the number of terminals and presents a number of

  cuts 2 which coincide with that of the terminals 4 in question.

  In this case, it is provided between two successive cutouts 2

  an ample window 7 through which is visible the reference

  this digital inscribed on the plate 8 which protrude the terminals 4, these references corresponding to each of the terminals in question. In all cases, the blade-shaped body

  the staple has two of its edges 9 bent perpendicular-

  the concrete and particular aim of giving rigidity

to its structure.

  As mentioned above, the circular orifices 3 formally

  at the ends of each cutout 2 make it possible to achieve perfect self-centering on the free ends of the terminals, which allows a quick and safe insertion of the clip into

question.

  The two trapezoidal fins 11 formed on both sides of the cutout 2, in connection with the orifices 3 themselves, which are bent outwardly as can be seen in detail in FIG. 2, determine, thanks to the elastic nature of their constituent material, a permanent pressure of the staple against the terminal or against the terminals 4, which

  ensures the optimal connection desired.

  Of course, various modifications may be made by the person skilled in the art to the devices or methods which have just been described by way of non-limiting example, without

depart from the scope of the invention.
