The electrical plug contains inside it the electrical contacts and is fed through a wire that penetrates in the body of the connector through its back part 104.
- connection with the male has to be fastened in such a way as to impede accidental unhooking and for this reason fast attachment systems are foreseen that connect the male to the female.
- these fast attachment systems have the shape of a shank 105 which is fixed by one of its ends 105' to the external casing 101 that forms the body of the connector.
- the opposite end terminates with a tooth 105" which, through an appropriate opening, has access in part to the seat 102, penetrating in the thickness of the casing.
- the male foresees an appropriate receiving seat or a complementary tooth that comes into contact with the end of the tooth 105" , realizing the block at the moment of the insertion.
- the tooth that is present in the complementary connector during its insertion in the seat 102, climbs over the tooth 105" , constraining themselves one against the other.

- the seat 21, by the way, is not essential for the unblock since, once the pushing of the button 11' has taken place, the two teeth are not in contrast anymore.

- the electrical plug 4 is made of Nylon plastic of the PA66 type with a three or six-pole connector.
Description
- The present invention concerns the technical field relative to industrial electric connectors.
- In particular, the invention refers to an industrial electric connector provided with an innovative retention/unhooking system that allows to connect it in a removable way to its complementary connector.
- Industrial electric connectors have long been known and serve to feed electrically various devices, such as, in the case in question, outdoor and indoor pumps/circulators to various apparatus, like solar thermal systems, boilers, floor heating systems, etc.
- These types of connectors, through an electric wire, are connected on one side to a current source, generally coming from an electric panel on the equipment, while on the opposite side they are connected in a removable way to a complementary connector installed on the device to feed.
- The connectors, as per
figure 1 of the prior art, foresees an electrical plug contained in a casing forming the body of the connector itself. The electrical plug is fed electrically through a wire that terminates in the body of the connector and, in turn, the plug transmits the current to the external device when it is connected to it through its complementary connector, which is inserted in the electrical plug. -
Figure 1 shows anexternal casing 101 which is hollow internally in such a way as to form alodging seat 102 inside which theelectrical plug 103 is placed. - As it is well known, the
electrical plug 103 serves to hold the male (complementary connector). To that aim, the electrical plug is provided with holes 103' in which the metallic terminals of the male are inserted. The electrical plug contains inside it the electrical contacts and is fed through a wire that penetrates in the body of the connector through itsback part 104. - The connection with the male has to be fastened in such a way as to impede accidental unhooking and for this reason fast attachment systems are foreseen that connect the male to the female.
- In the background art, always with reference to
figure 1 , these fast attachment systems have the shape of ashank 105 which is fixed by one of its ends 105' to theexternal casing 101 that forms the body of the connector. The opposite end, instead, terminates with atooth 105" which, through an appropriate opening, has access in part to theseat 102, penetrating in the thickness of the casing. The male foresees an appropriate receiving seat or a complementary tooth that comes into contact with the end of thetooth 105" , realizing the block at the moment of the insertion. In particular, the tooth that is present in the complementary connector, during its insertion in theseat 102, climbs over thetooth 105" , constraining themselves one against the other. - To operate the removal of the male electric connector (complementary) it is therefore necessary to manually operate the lifting of the
shank 105 in such a way that the tooth disengages, allowing its removal. When the male connector has exited, the shank is released and goes back elastically to the initial position. To make an insertion it is therefore enough to insert again the male inside the seat until the tooth snaps, i.e. it engages in a pre-established point of the male connector, blocking it in position. - It is clear that this solution presents various technical inconveniences.
- For example, the removal of the male connector is not easy because it is not easy to operate the lifting of the shank. It is required to act with the tip of the fingers and this operation can produce abrasions.
- Moreover, if the shank is excessively forced, it can be broken, rendering the entire connector not usable. It is therefore clear that this solution lends itself well to accidental breakings.
EP 0 942 495 A1 andUS 7 077 683 B1 disclose electrical connectors according to the preamble of claim 1. - It is therefore the aim of the present invention to provide an innovative electric connector that solves at least in part said technical inconveniences.
- In particular, it is the aim of the present invention to provide an industrial electric connector wherein the retainlunhooking device of the internal plug satisfy to regulation requirements that impose a traction resistance superior to the 100 N, in such a way as to result applicable in many different sectors.
- It is also the aim of the present invention to provide an industrial connector wherein the retain/unhooking device is such as to allow an unhooking that is fast, simple and does not imply risks of abrasions for the user.
- Last, it is the aim of the present invention to provide an industrial connector provided with a retain/unhooking device that results long-lasting.
- These aims are reached with the present electric connector 1 according to the invention.
- The electric connector (1) is suitable for coupling in a releasable way to a complementary electric connector (100).
- The electric connector (1) according to the invention is disclosed in claim 1. This solution easily solves said technical problems.
- It is not necessary anymore to operate a difficult lifting of the shank to disengage the tooth from the complementary connector, with the risk of injuries or breakings. The solution proposed allows the unhooking by simply acting using pressure on a button, i.e. by pressing the button. Not only does this solution cause abrasions but, above all, is much more solid and long-lasting than the preceding one. The engaging element (41), in the shape of a tooth, for example, is integral to the slab, therefore a sliding of the slab causes a disengagement of this tooth with the complementary engaging element. The action of crushing between the engaging elements (41, 42) in the unhooking phase is certainly safer against breakings with respect to an operation of lifting of the shank.
- The present solution, further, does not require modifications of the complementary electric connector, which continue productively to maintain their original configuration. This solution, therefore, adapts itself well to the block of complementary electric connectors already in commerce without requiring their adapting structural modification.
- Further advantages can be deduced from the dependent claims.
- Further characteristics and advantages of the present industrial electric connector, according to the invention, will result clearer with the description that follows of some embodiments, made to illustrate but not to limit, with reference to the annexed drawing, wherein:
-
Figure 1 represents an axonometric view of a connector in accordance with the background art; -
Figure 2 represents an axonometric view of the industrial electric connector in accordance with the invention; -
Figure 3 shows an exploded view of the connector offigure 2 ; -
Figure 4 and figure 5 show a technical detail, in axonometry, of the fast hooking/unhooking device in accordance with the invention; -
Figure 6 shows the same solution in a top view; - Figures from 7 to 11 show possible forms of electric connector that couples to a complementary
electric connector 100; -
Figure 12 andfigure 13 show in an axonometric view the teeth (41, 42) to connect thecomplementary connector 100 to theplug 4; -
Figure 12A highlights the gap between the U-shaped guide, where theslab 11 is placed slidingly, and the body of theplug 4 in such a way as to allow the insertion of thetooth 42 of the complementary connector that engages with thetooth 41; -
Figure 14 shows a variant wherein the spring is integrated directly in the body of the slab, in particular it is a bent appendix of the slab. - With reference to
figure 2 , an industrial connector is highlighted in accordance with the present invention. - The industrial connector 1 foresees an
external casing 2, for example generally L-shaped. It forms aninternal seat 3 suitable for holding, in a permanent way, anelectrical plug 4. - The
external casing 2 is, preferably but not necessarily, realized in PVC so as to be easily moulded with well-known mould processes as per the background art. -
Figure 3 shows in an exploded view the essential components. Theelectrical plug 4 is therefore highlighted, removed from theseat 3 just for descriptive clarity purposes. Always infigure 3 theelectric wire 20 is highlighted that feeds the current to theplug 4.Figure 2 highlights thewire 20 that enters in thecasing 2 of the connector through itsback part 5. - Always
figure 3 highlights, according to the background art, the three or moreelectrical contacts 7 that are connected from one of their parts to thewire 20. To that aim, thewire 20 foresees three or more corresponding branches 20' that engage in the appropriate connections 7' found at the end of thecontacts 7. - The
electric contacts 7 result inserted in the body of theplug 4 and the branches 20' engage in the hooks 7', penetrating through theholes 8 of the plug 4 (see dotted lines that join the branches 20' to the holes 8). -
Figure 2 , likefigure 3 as well, shows the hooking/unhookingdevice 10 that is the subject of the invention. - This device foresees a
slab 11, for example made of plastic, of such a length that when applied, as described right below, one of its exceeding parts 11' exits from the casing forming a button. Thecasing 2 foresees anopening 50 through which the end 11' of theslab 11 can exit. The slab is slidingly assembled inside aguide 12 and brings integral to it atooth 41. The guide is found integral to the body of the plug but it could also be separate and then connected in the production phase. - As shown in
figure 5 , for example, the guide is preferably constituted by a U-shaped element open from one side and that forms the twosides - As it is then highlighted in
figure 12A , the U-shaped guide is connected or integral to theplug 4 in such a way as to result distanced from it of a pre-determined quantity. In this way, as better clarified below, thetooth 41 offigure 12 belonging to the slab exits from the guide, facing theplug 4. - The casing itself 2 forms a constraint against a
shoulder 40 of theslab 11 to impede the exit of the slab from theopening 50 and, therefore, limiting the exit of the single end 11' that has the function of unhooking button. Alternatively, a stop could be foreseen, directly found on a side (13, 14) of the U-shaped seat. - The U-shaped element therefore terminates with a
support base 15. Bothfigure 4 and figure 5 highlight an elastic spring 16 (for example, of compression) which is arranged inside the U-shaped element in such a way as to result comprised between thesupport base 15 and theslab 11 assembled slidingly inside the U-shaped element itself. - In particular, as highlighted in
figure 5 , the spring is fixed on one side to thesupport base 15 and on the opposite side to a point of the slab. - In this particular solution of
figure 5 , the fixing of thespring 16 to theslab 11 is obtained by conforming in a particular way the slab itself, as described right below. - The slab foresees a
cut 21 that generates a lower side 21' and a passage channel that goes from the side 21' to theside 22 and in which to insert the end of the spring. The passage channel of the spring therefore starts from thebase 22 of theslab 11 and terminates on the lower side 21'. The path of the channel is inclined in such a way as to follow the profile of the terminal section of spring that is inserted in it. The exceeding part of spring that exits from the opening 21' is bent in such a way as to constrain, the spring to the slab. This solution has the advantage of realizing a simple connection and guarantees an optimal coaxiality between spring and button and therefore a precise functioning. - Obviously, other connection systems could anyway be realized without for this moving apart from the present invective concept.
- For example, in a variant it would be possible to avoid the realization of the channel that joins the
side 22 to the side 21' and glue or weld the end of the spring directly to theside 22. - As shown in
figure 6 , therefore, the slab exits from thecasing 2 through anappropriate opening 50 found in said casing. The exceeding part 11' of slab that exits from the cut therefore forms a fast unhooking button. - In a further variant, shown in
figure 14 , the spring is substituted by anappendix 216 elastically flexible and found directly in theslab 11. On the basis of the thickness of the appendix, it will result adjustable in flexibility, acting exactly as a spring integrated to the slab. - Going back to
figure 5 orfigure 3 , these show theshoulder 40, for instance, found in the slab and that goes in contrast against the casing in such a way that the slab is not expelled by the push action of the spring. - In the realization phase, the
entire plug 4 is assembled together with thecontacts 7 and the electric wires 20', and thecasing 2 is moulded around these elements. - Figures from 7 to 11 show many different types of electric connectors 1 connectable to a
complementary connector 100. For example,figure 11 shows theseats 101 where thecontacts 102 are placed, which hold thecontacts 7 of the connector 1. - As shown in
figure 12 , the slab (obviously in all the embodiments described) also foresees integrated in it ablock element 41, in the shape of atooth 41, for example, which is configured to engage against anequivalent block element 42, such as atooth 42, belonging to themale connector 100 and highlighted both infigure 7 and infigure 13 . -
Figure 13 shows thecut 21 to allow, as better clarified right below, an enhanced extraction of themale connector 100 with respect to the electrical plug 1. - In use, therefore, as shown in
figure 12 , the spring maintains the slab all extended in such a way that the exceeding part 11' of slab that exits from thecasing 2 forms the release button for the user. The slab, thanks to itsshoulder 40, stops against the casing and is not expelled. - In this position, the
tooth 42 of the male 100, at the moment of the insertion, results in line (therefore in the insertion trajectory) with thetooth 41 of the slab. Thetooth 41 exits from the guide and faces the plug through the gap described with reference tofigure 12A . In this way, during the insertion of thecomplementary plug 100, the teeth intercept themselves and the climbing over of thetooth 42 on thetooth 41 takes place. Once the climbing over has taken place, the flat face 42' is found in contrast against the flat face 41' , realizing the block. In this position, themale connector 100 is impeded from exiting also if a high traction force is applied, since thetooth 42 is in contrast against thetooth 41. - To operate the release, it is necessary to push the
button 11, i.e. the exceeding part 11' of slab that exits from the casing. So during the crushing of the slab, the flat face 41' of thetooth 41 slides on the flat face 42' of thetooth 42, realizing a disengagement of the teeth and thus bringing thetooth 42 in line with theseat 21. In this position, not being the teeth in contrast one against the other anymore, thetooth 42 is free to slide into theseat 21, appropriately wide, allowing the unhooking that allows to extract the male 100 from theplug 4. - From what has been described about the functioning, it is now clear that, in a further variant of the invention, the U-shaped guide found integral to the plug could be instead found directly in the casing and, as usual, open from one side in such a way that the
tooth 41 belonging to the slab faces theplug 4, appropriately distanced to allow the insertion of thetooth 42 belonging to thecomplementary connector 100. - In order to favour the climbing over of the
tooth 42 it is clear that theteeth figure 13 atooth 42 is shown that presents aninclined face 42" complementary to theinclined face 41" of thetooth 41. The inclined faces realize inclined surfaces that facilitate the snap and therefore the reciprocal climbing over for the block. - It is clear that equivalent realization solutions are possible.
- For instance, always with reference to
figure 12 or13 , it can be foreseen that the sliding U-shaped seat of the slab is of such a height as to allow a minimal vertical play of theslab 11. In this way, the insertion would be enhanced by lifting a little the slab during the insertion of thecomplementary connector 100 that would favour the climbing over of thetooth 42 on thetooth 41. - Alternatively, a system of tighter tolerances can be realized, resorting to precise dimensions of the teeth (42, 41) and to the yielding of the materials, so as to obtain a safer block.
- The
seat 21, by the way, is not essential for the unblock since, once the pushing of the button 11' has taken place, the two teeth are not in contrast anymore. It is clear that aseat 21 eliminates completely the eventual rubbing friction that would be created between the crest of thetooth 42 and the surface of the slab itself during the removal phase, thus facilitating the extraction significantly. - Preferably, but not necessarily, the
electrical plug 4 is made of Nylon plastic of the PA66 type with a three or six-pole connector.
