Definitions
- the present invention relates to a connection device essentially consisting of tabs fixed at regular intervals with at least one conductive core housed in an envelope insulating, said tabs protruding from the envelope for their connection to electrical terminals.
- connection can be connected to electrical devices modular fixed side by side on a standard support rail, and it makes then as a bypass bar.
- said bridging bar or more generally the connection device is flexible and elastic, and made for example in the form of a bar continue cutting to the desired length for the application made of it. In this case, it can easily be stored on a roll, and unwound as you want to cut some sections.
- the invention can be manufactured in the form of sections of precise lengths, corresponding by example to the width of electrical cabinets or fixtures that we want to install.
- connection device When the connection device is used with classic modular devices, mechanical properties mentioned above ensure compatibility between modular devices with different bridging levels, such as devices from different manufacturers, or devices from ranges staggered in time.
- Modular electrical devices have a housing insulating material which can be fixed to a standardized profile support rail.
- Said housing for this purpose comprises a base with a recess of shape longitudinal limited at its ends on the one hand by a notch and on the other hand by a locking latch, allowing the housing to be fixed to the edges of the rail. Disassembly must be carried out in relation to a device overcoming the devices arranged on their rail.
- connection device then acting as a comb are therefore intended to be connected to the terminals of the devices modules located on the same side as the notch, therefore opposite sliding latch.
- the base of the device may for example include a second sliding latch so that the device can be moved in a direction parallel to the axis of its sole with a stroke sufficient for the comb tongue is extracted from the terminal, making disassembly possible individual of said device.
- the addition of a second latch implies obviously multiple changes in the design of the device, which weigh heavily in terms of industrial process and generally result in increase the cost of products. Such a solution only applies more than for devices produced automatically with a second latch, which cannot obviously not retrofit devices from more ranges old.
- connection of the invention is mainly characterized in that the one or more conductive cores and the insulating jacket are made of a material flexible, the relative position of the tongues, of the core (s) and of the insulating jacket being fixed uniformly over the entire length of the device by the insulating envelope so as to form a structure continuous flexible and elastic of any length with a spatial periodicity equal to the distance between two consecutive tabs.
- a flexible structure surrounds at least one conductive core of axial shape on which are fixed periodically connecting tabs.
- the insulating envelope consists of an insulating coating flexible and elastic surrounding the conductive core (s) and a portion of the tabs attached to it.
- Elasticity which is not required for, for example, storage in reels, on the other hand is strictly necessary to ensure high dismountability, as well as compatibility between devices with non-bridging levels uniforms.
- said insulating coating is produced by overmolding of material flexible and elastic plastic around the structure consisting of the core or conductive cores fitted with tabs.
- the insulating coating should have a elasticity allowing transverse displacement of a tongue when the two adjacent tabs are locked.
- each conductive core consists of a braid conductive metal strand.
- the flexibility requirement naturally also accommodates other configurations of the conductive core, which can be implemented in the part of the invention.
- the multi-strand braid has many advantages: it is particularly easy to adapt to the amperage, and facilitates the fixing the tabs.
- the latter are preferably made of metal strips soldered or crimped to the flexible conductive core (s). They are for example produced by cutting from conductive strips and they have, for a given device of the invention, a geometry and identical dimensions.
- tabs depending on the application which is made of said device, for example in the form of a bridging comb, can be sectioned at the outlet of the insulator, in particular when said comb is applied to a double device without two adjacent connection terminals on its small faces (differential circuit breaker ).
- each metal strip has of a reduced width end intended to be inserted into a lumen practiced in the body of the coverslip after folding in a loop of said end around a conductive core, the part of said end which protrudes from the light then being widened to secure the loop.
- each strip is welded to two multi-strand braids.
- a configuration with two distinct cores can in particular be justified by the intensity of the current expected to be conveyed in the device connection of the invention. Multiple other configurations are fine heard feasible, including with separate rows of slats, if the need arises.
- FIG. 1 in fact illustrates the heart of the invention: at least one cable or wire flexible conductor (1) on which are fixed, at regular intervals, connection tabs (2).
- said flexible wire (1) consists of a multi-strand braid.
- Said tabs (2) are composed of a rectilinear part (3) intended to be inserted into the connection terminal by example of a modular electrical appliance, and of a folded part (4), instead of attachment to the wire (1)).
- these tongues (2) are made from strips cut from a strip of conductive material, for example copper.
- the length of the end (5) of reduced section is provided so that that a tightening can be exerted on the braid (1) (see figure 2), and that the end of this part, protruding from the light (6), can be widened for example by hammering to block the connection.
- Figure 4 shows a variant with two braids (1, 1 ') on which are welded the tabs (2).
- the portion (7) of the tabs on which the braids (1, 1 ') are fixed has a planar appearance, offset from the straight portion (3) of the tongue, and of sufficient area to receive two compacted portions (8) of the braids (1, 1 ').
- the conductor assembly described in Figure above is coated with a flexible insulating material (9) forming a flexible structure with protruding tabs (2).
- a bridging comb produced according to this variant can be manufactured in predetermined lengths.
- the side ends are coated an insulating layer protecting the end of the conductive braid (1).
- the structure of FIG. 5 can be manufactured by the meter or the roll and cut to the desired length by the user, on and according to the needs of the site.
- the conductive braids (1) are flush with the severed ends, and it is necessary to provide a protective cap (not shown).
- This mode of manufacturing offers the advantage of not constitute of fall: only the quantity strictly necessary for the realization of the comb is sectioned.
- the connection device configuration shown in this figure can also be stored on rolls or reels, which is another defining advantage.
- the manufacturing of this configuration can be done by injection molding of insulating plastic.
- FIG 6 there is shown a row of modular devices (10) fixed on a standardized rail (11), one of these modular devices (10) being in progress mounting / dismounting, and therefore laterally offset from the others.
- the bridging bar of the invention is fixed, via the tabs (2) in the terminals for connecting the devices (10) contiguous to that which is extracts / inserts, but the elasticity and flexibility of the device of the invention however allow the deformation of said bar at the device (10) to extract / insert.
- This deformation obviously implies that the braids (1, 1 ') have a sufficient length, between two tabs (2), to absorb said deformation.
