Description

Pair of plug-in contacts.

The present invention relates to a pair of plug-in contacts for a power supply network.

The invention relates to the laying of a network electrical and to the connection of devices and devices to the network electric In particular, the invention relates to contacts plug-ins that can be attached to each other and allow connection between various components of the electricity grid.

In such application objectives that probably require further adjustment of the electrical wiring, it is desirable that from the outset these are already foreseen adjustments at the time of building the power grid, to Simplify your future execution. This type of demand is usually pose, for example, in the exhibition stand structures commercial and in office and commercial buildings transformable, in which in all probability the situation of the dividing walls, for example, should be changed in some moment. If the couplings of the electrical devices (for example, lighting fixtures and plugs) for said sites are initially carried out in the manner conventional, that is, connecting the electrical devices to the electrical network through a fixed cable installation, the rear transfer of electrical devices will be very slow and uncomfortable. Also, in the first stage of installation (that is, when the wiring is carried out by first time in a construction), installation work performed as a conventional fixed installation results relatively slow

Therefore, instead of the conventional solution described above based on screw connections, a solution is presented in which the electrical devices, branch pieces and even the cables to be used in the wiring are provided from the beginning. (factory) with specific plug-in contacts. Therefore, in practice, the electrical installation work that must be carried out on site consists in mutually connecting the plug-in contacts of the cables and other devices in the desired manner. Obviously, this installation mode is much faster than the mode in which electrical devices need to be coupled with fixed cables.

In order to ensure that the plug-in contacts remain in place and therefore prevent them from establish loose electrical contacts, plug-in contacts acquaintances are provided with hitching means, thanks to the which the female contacts and the male contacts that fit they are hooked together at the time of installation. One of the plug-in contacts to be attached have at least an attachment element that can be disengaged and, in turn, the another presents a fixed complementary part of the element of hitch that can be disengaged. In practice, the hitch is effect in such a way that the coupling element joins said complementary piece. Therefore, if a force is exerted, by example, pushing by hand, on the hitch element that can be disengaged, plug-in contacts can disengage and the contacts can disengage one of the other.

The biggest drawback of contacts known plug-ins described above is that the release Two plug-in contacts can only be carried out through a plug-in contact. In practice, this creates problems, since the plug-in contact that has an element Hitch that can be used for disengagement should be placed on the device so that the hitch element is not accessible (or at least not easily accessible). These situations originate, for example, in shunt pieces or the electrical devices that are part of the electricity grid such as a lighting fixture with a contact of output for power supply from an input contact to a lamp of the lighting fixture, and from the contact Output to other electrical devices. In these applications, it is necessary to uselessly extract many pieces of the devices electrical, often using special tools, to be able to access the coupling elements that can be disengaged from the plug-in contact and disengage the two contacts pluggable

In US Patent No. 4,501,459, a electrical connector with coupling means to hold two connectors with each other. In this solution, the hooking means are located on the upper side and the lower side of the connector. This hinders access to the coupling means, in particular, if the connector is used in an installation where they have connected several similar connectors, one below the other, as is usually the case, for example, of bypass devices. Other disadvantage of this solution is that there are no male connectors and female separated. Instead, you can connect any pair of connectors with each other by rotating one of the connectors 180 °. Bliss solution significantly increases the risk of errors network assembly.

Also, in US Patent No. 3,569,909, it is given to know a plug-in contact with hook-shaped parts elongated that are attached to the corresponding parts in the form of hook of an opposite plug-in connector. The parts in the form of This solution's hook is designed in such a way that the parts Hook-shaped one of the contacts present the part open directed towards the plug connector body, while that the hook-shaped parts of the other plug-in contact presents the open part directed in the opposite direction to the body of the connector The difference in form between the parts in the form of elongated hook implies that the user of the plug-in connector on the practice will need to see the hook-shaped parts to be able to determine how force should be applied to the parts in the form of hook when trying to unhook the two plug-in contacts. Therefore, the plug-in connector is not very easy to handle for the user, since in practice it is often it is necessary to use these contacts in locations where it is very difficult to observe the elongated hook-shaped parts.

The objective of the present invention is to solve the problem described above and provide a solution through from which the plug-in contacts can be disengaged further easily than before, so that, in this way, the installation and uninstallation of the power grid, the connection of appliances and devices to the mains and disconnection of themselves and the extension of the electricity network can be carried out faster and more flexible than before, and through the which the previous operations cause the least possible amount of alterations in the environment. This goal is achieved with the pair of plug-in contacts for a power supply network according to the present invention The pair of plug-in contacts consists of a male contact and a female contact. The male contact comprises a body that has an upper side and a lower side, means of connection to receive at least two first electrical cables and, at least two first elongate coupling elements parallel coupled to the connection means of the male contact, delimiting said first elongate coupling elements a plane that intersects with the lateral faces of the male contact and being located all the coupling elements of said male contact in said plane. The female contact comprises a body presenting an upper side and a lower side, means of connection to receive at least two seconds electrical wires and at least two seconds elongated coupling elements parallels coupled with the connection means of the female contact, delimiting said second elongate coupling means a plane that intersects with the lateral faces of the male contact and being located all the coupling elements of said female contact in said plane. The first elements of coupling of the male contact and the second elements of Female contact coupling are designed to be parts complementary to each other, being able to engage each other to allow electrical contact between the first and second cables electric. The male and female contacts are provided with means of hitch that hold the male and female contacts with each other when the first and second coupling elements are couple with each other, understanding the hooking means of each contact at least one elongated element attached to the side face of the body by means of an arm, located at a proximal end, which it presents a hook-shaped part intended to be attached to the corresponding hook-shaped part of the plug-in contact opposite. The arms of the male contact and the female contact, respectively, they are located between the respective ends proximal and distal free of the respective elongated elements. Said arm of the respective plug-in contact yields, which determines that the position of the elongated element changes and the part in the form of a hook detaches from the hooked part of the opposite plug-in contact, when exerted on the element elongated a force directed towards the body of any of the plug-in contacts or in reverse. The shaped part of hook of one of the plug-in contacts presents the part open directed up and to the side and limited to the proximal and down end, and the hook-shaped part of the another plug-in contact presents the open part directed towards down and to the side and limited towards the proximal end and towards above, when the upper sides of the contact bodies Plug-ins are seen from above.

The present invention is based on the idea that, when the male contact and the female contact are provided with coupling elements that can be used for disengagement, these two contacts can be disengaged by means of any of the contacts, in such a way that in no case the contact of the pair of plug-in contacts of which the hooking element that can be disengaged will be located in a inaccessible place. Therefore, the pair of plug-in contacts according to the present invention facilitates the release of the two plug-in contacts and, consequently, installation and uninstallation of electrical networks, and also determines that the execution of adjustments in the couplings is much more flexible and easy.

Next, the present invention will be will describe in more detail by way of example, in relation to With the drawing attached.

Figure 1 illustrates the first form of preferred embodiment of the pair of plug-in contacts of the present invention On the left side of Figure 1, it is shown the male contact 1 from two different viewing angles, and in the right side, female contact 2 is shown from two angles of different vision Connection means 4 and 5 to receive three separate electrical cables are located in bodies 3 of the male contact 1 and female contact 2. In this way, the ends of separate electrical wires are introduced by the openings 5 and, after being connected to the plug-in contacts, fastened with clamping screws 4.

The connection means 4 and 5 of the male contact they are coupled to pin-shaped coupling elements 6, one of which is illustrated in Figure 1 by lines discontinuous The coupling element 6 is located within a 7-shaped plastic plug that protrudes from the body 3 of the contact 1. In the lower figure illustrating the contact male, the opening 8 of the plastic plug in the form of barrel 7.

In parallel, the connection means 4 and 5 of the female contact 2 are coupled to the elements of barrel-shaped coupling 9, one of which is illustrated by dashed lines in Figure 1. The element of barrel-shaped coupling 9 is located in a formed cavity by a piece of plastic 10 protruding from the body 3 of the female contact 1. In the lower figure illustrating the contact female, the opening 11 of the cavity is shown.

When the male contact and the female contact of Figure 1 connect to each other, the plastic plug 7 of the male contact 1 is introduced through the opening of cavity 11 of the female contact, such that the coupling element in Pin shape 6 of the male contact is inserted into the element 9-shaped coupling of the female contact, thereby establishing a contact between the elements of coupling 6 and 9.

The male and female contacts of Figure 1 they comprise hooking means that connect the plug-in contacts when the coupling elements 6 and 9 are connected to each other. In In the case of Figure 1, the coupling means comprise the elongated elements 12 and 13 with hook-shaped parts 14 and 15. In the case of Figure 1, the elongated elements 12 of the contact male 1 shown on the left side comprise parts in the form of hook 14 presenting the open part directed upwards. Of the similarly, the elongate elements 13 of the female contact 2 shown on the right side comprise hook-shaped parts 15 that present the open part directed downwards. Thus, elongated elements 12 and 13 of the plug-in contacts are hold each other by hook-shaped parts 14 and 15, when plug-in contacts 1 and 2 connect to each other.

Elongated elements 12 and 13 are attached to the 3 body of the plug-in contacts with a protruding arm 16 of the body. Since said arm 16 and elongate elements 12 and 13 are made of flexible / elastic plastic, the hitch between elongated elements can break exerting a force, oriented towards body 3 or the opposite direction of body 3, on the elongated elements 12 and 13 of any of the plug-in contacts 1 6 2. As a result, said elongated element or arm 16 bends and, thus, the parts in hook shape 14 and 15 disengage from each other.

The above description and figures related are only intended to be illustrative of this invention. As will be obvious to those skilled in the art, the The present invention can be varied and modified in various ways. ways without departing from the scope and essence of the invention such as defined in the appended claims.
