Definitions

• Double comb interconnection device Double comb interconnection device
• the present invention relates to interconnection devices used in particular and not exclusively for ensuring the interconnection of connection and / or link terminals arranged in line.
• the invention relates to an interconnection device comprising a first and a second interconnection combs arranged facing each other and which each comprise a connecting bar, and teeth which extend substantially perpendicularly from the connecting bar, the device comprising elastic teeth and rigid teeth.
• Such an interconnection device is used to connect several electrical conductors and put them at the same potential. More particularly, this device allows the interconnection of conductive bars in which slots are made intended to each receive two teeth of the device located opposite.
• Such devices are notably known from document EP-678 934 in which two interconnection combs are arranged opposite.
• One of these combs comprises only rigid teeth and the other comb comprises only elastic teeth, the rigid teeth being made of an electrically conductive material to ensure the passage of current while the elastic teeth being made of stainless steel and have a sufficient elasticity to ensure good contact at the level of rigid teeth.
• the elastic teeth are deformed so that the interconnection device as a whole is unbalanced, it can for example tilt under the effect of the elastic forces all acting in the same direction.
• only one is conductive, there is a heating force due to the passage of current.
• interconnection devices which include two combs of which all the teeth are conductive and are elastic. Even if this device has the advantage of being balanced since two teeth facing each other are symmetrical, no tooth makes it possible to take up the elastic forces exerted by the other teeth so that this device is subjected to numerous stresses.
• the object of the present invention is in particular to remedy these drawbacks by providing an interconnection device which is balanced while having good electrical conductivity, with simple, effective and inexpensive means.
• the interconnection device of the aforementioned type is essentially characterized in that the teeth of each of the first and second combs are alternately rigid and elastic, and in that the elastic teeth and the rigid teeth of the first comb are located respectively opposite the rigid teeth and elastic teeth of the second comb.
• the interconnection device has pairs of teeth in which one of the teeth is able to take up the elastic forces of the other of the teeth while each pair of teeth exerts an elastic force whose direction is opposite to the elastic force exerted by the neighboring pair.
• the interconnection device is thus balanced as a whole.
• the teeth of the first and second combs are all made of an electrically conductive material.
• one of the teeth does not undergo a temperature rise greater than the other of the teeth.
• the elastic teeth each comprise a base section and an end section which form an obtuse angle between them.
• the basic section forms an angle with the plane in which the connecting bar is inscribed.
• the elastic teeth each comprise a depression of short length relative to the length of the teeth, which is turned away from the rigid tooth opposite and which extends over the base and end sections.
• the rigid teeth have a concave cross section, the concavity of which faces the elastic tooth opposite.
• the elastic teeth and the rigid teeth each have free ends which converge towards the opposite tooth.
• the connecting bars of the first and second combs are integrally formed by being folded over one another.
• the first and second combs are made of a copper alloy material.
• Figure 1 is a perspective view of the interconnection device according to the present invention, ready to be inserted into connecting bars.
• FIG. 2 is a partial perspective view of one of the combs of the interconnection device of FIG. 1.
• Figure 3 is a side view of two teeth located opposite belonging to the first and second combs of the interconnection device.
• Figure 4 is a sectional view along line IV-IV of Figure 3.
• Figure 5 is a top view of the interconnection device during manufacture, before the two combs are folded one on the 'other.
• FIG. 1 represents an interconnection device 1 as well as four connection bars 2 which are associated with a connection and / or connection terminal, not shown. These connecting bars are arranged in line, and each comprise a slot 3 of substantially rectangular shape, extending transversely relative to the bar. The different slots 3 are aligned with each other to allow the creation of an interconnection between at least two connecting bars 2.
• the interconnection device 1 comprises a first interconnection comb 5 and a second interconnection comb 6 which are arranged opposite. Each of these two interconnection combs 5, 6 has a connecting bar 8 also called base of the comb. From each of these connecting bars 8 extends a number of teeth. In the present case, each comb comprises ten teeth which extend substantially perpendicularly from the respective connecting bar 8, and which are divided into two groups of teeth, on the one hand, elastic teeth 10 and, on the other apart, rigid teeth 11.
• the succession of teeth alternately comprises elastic teeth 10 and teeth rigid 11.
• Each tooth of the first comb 5 is located opposite a tooth of the second comb 6 and the elastic teeth 10 of the first comb 5 are offset relative to the elastic teeth 10 of the second comb 6, so that an elastic tooth 10 of the first comb 5 is located opposite a rigid tooth 11 of the second comb 6.
• each pair of teeth located opposite comprises an elastic tooth and a rigid tooth, and in the succession of pairs of teeth of the interconnection device 1, each pair is the mirror symmetry of a neighboring pair.
• each elastic and rigid tooth 10 is of generally rectangular shape and is made of an electrically conductive material.
• each elastic tooth 10 comprises a base section 12 located on the side of the connecting bar 8 and an opposite end section 13, located forward in the direction of introduction of the tooth in one of the connecting bars 2.
• the base section 12 forms with the end section 13 an acute angle, so that the elastic tooth 10 is elastically deformable perpendicular to the plane of the interconnection device 1.
• the base section 12 forms a certain angle with the connecting bar 8 which supports it, so that this base section 12 is inclined relative to the plane of the interconnection device 1.
• Each elastic tooth 10 comprises in addition to a depression 14 which extends both over the base section 12 and the end section 13. This depression is of short length relative to the length of the tooth which supports it and is turned opposite the rigid tooth 11 located opposite.
• This depression 14 is for example produced by stamping the tooth 10, and makes it possible to further improve the contact with the slot 3 of the bar 2, into which the tooth is intended to be inserted.
• the rigid teeth 11 extend substantially in the plane defined by the interconnection comb 1, being of cross section of concave shape, the concavity of which faces the elastic tooth 10 situated opposite. This concave shape extends almost over the entire length of the tooth and allows good rigidity of the tooth 11.
• the elastic teeth 10 and the rigid teeth 11 also each have free ends 15, 16 situated at the ends of these teeth and who converge on the opposite tooth. These folded ends 15 and 16 make it easier to insert the teeth into the slots 3 of the connecting bars 2.
• the first comb 5 and the second comb 6 are preferably integrally formed at their respective connecting bars 8.
• the whole of the interconnection device 1 is made flat by cutting, stamping and folding. After cutting and stamping, the two combs 5 and 6 are folded over one another by folding at their connecting bars 8.
• the interconnection device 1 according to the present invention provides a great improvement to the existing technique in providing an interconnection comb whose structure is balanced since the forces exerted by each elastic tooth in a pair are in the opposite direction to the forces of the elastic tooth of the neighboring pair.
• the entire interconnection device is made of a copper alloy, all the teeth are conductive and there is therefore no rise in temperature of one of the teeth relative to the others.
• the invention is not limited to the sole embodiment of the two combs previously described by way of example, on the contrary it embraces all variants.
• the number of constituent teeth could be only two, without departing from the scope of the present invention.
