Description

Technical Field

[0001] The invention belongs to the technical field of electrical connectors, in particular to the technical field of technical connectors for drive belts or tensioning belts of lifts. The invention relates to electrical connectors and electrical connection systems. In a specific embodiment, the invention is used in the field of lifts and / or elevators for both people and loads.

[0002] Likewise, the invention relates to a method for assembling said electrical connection system, and to a method for measuring the wear and / or breakage of a drive belt. Background Art

[0003] Today, the technical field of connectors for drive belts comprises known examples of connectors allowing electrical contact between metal cables embedded in said drive belt or carrier belt.

[0004] The carrier belt is formed by a stranded cable made of metal wire, usually steel wire, which constitutes a carrier element or cable, which is embedded in a plastic matrix, in particular a polymer matrix. The stranded cables are arranged in parallel, and the plastic matrix is ​​essentially used for environmental protection, maintaining the distance between the cables and reducing the friction between the stranded cables and other external elements, pulleys and other mechanisms of the machine. Therefore, the carrier belt constructed in this way is in the form of a flat, elongated belt, in which parallel metal cables with a substantially straight path are included. Although a carrier element with such a structure offers advantages in terms of flexibility compared to conventional drive cables, the plastic matrix-based configuration of the carrier element causes problems because it hinders or prevents visual inspection of the metal cables accommodated in the carrier element due to the plastic matrix being an opaque material.

[0005] In the prior art, there are several methods for checking the status of the load-bearing cables in configurations such as the one mentioned above, most of which are based on changes in the electrical characteristics of the load-bearing cables, which occur when the cables undergo normal wear or expected deterioration, which requires direct access to the load-bearing cables.

[0006] In this sense, in order to access the interior of the carrier tape and thus directly access the carrier cables accommodated therein, current electrical connectors have piercing elements which penetrate the plastic material of the drive tape by force until the piercing elements laterally contact the metal cables.

[0007] Therefore, the piercing elements must have sufficient length to be able to penetrate the entire layer of plastic material and thereby contact the metal cable inside. Further, these piercing elements must also have a sharp end that can be introduced into the plastic material and completely penetrate the plastic material until the sharp end reaches the metal cable.

[0008] This requires a compromise, considering that in the case where the piercing element is extremely small to facilitate entry into the drive belt, the piercing element may undergo deformation and have a diverting path. In other cases, if the piercing element is fragile, the applied force required to obtain a suitable path to the metal cable may cause the piercing element to break.

[0009] Furthermore, in the case of a solid piercing element, insertion into a plastic material is further complicated, where the resistance exerted by the plastic material may be higher than the force exerted when inserting the piercing element, thereby requiring additional force to achieve contact. Summary of the invention

[0010] The invention relates to an electrical connector for a drive belt which, in operating mode, allows an electrical connection to a metal cable embedded in the plastic material of the drive belt.

[0011] In addition, the present invention also relates to an electrical connection system and a method for assembling the electrical connection system.

[0012] Finally, the invention also relates to a method for measuring wear and / or breakage of a drive belt.

[0013] A first aspect of the invention relates to an electrical connector for a drive belt, characterized in that the electrical connector comprises:

[0014] - a body extending according to a longitudinal direction XX', wherein the body comprises:

[0015] ○Inner shell,

[0016] ○ a first end, and

[0017] o a second end, the second end comprising an opening allowing access to the inner housing,

[0018] - a contact device which is accommodated in the inner housing and is oriented toward the second end according to the longitudinal direction XX'.

[0019] Advantageously, the body of the connector allows the contact means to be housed in means allowing protection of the body, said body being a rigid element.

[0020] An opening present at the second end of the body allows access to the inner housing and therefore to the contact means. In a particular embodiment, the opening has a rectangular cross-section adapted to accommodate the cross-section of the drive belt.

[0021] In a particular embodiment, the contact means comprises a plurality of projections which are oriented towards the second end and thus towards the opening of the second end.

[0022] In particular embodiments, at least one protrusion of the plurality of protrusions includes a sharpened end configured for piercing or passing through the external element.

[0023] In particular embodiments, at least one protrusion of the plurality of protrusions includes a planar end configured to contact a planar surface of an external element.

[0024] In a particular embodiment, the contact means is arranged at a point of the inner housing of the body adjacent to the opening of the second end.

[0025] In a particular embodiment, the body is constructed from at least two parts, which are preferably attached to each other by means of a snap fit and / or a threaded attachment and / or a riveted attachment.

[0026] In a particular embodiment, at least one portion of the body is made of an insulating material, such as plastic, resin, etc. Advantageously, this allows any electrical connections established in the body to be isolated.

[0027] In a specific embodiment, the electrical connector further comprises electrical connection means connected to the contact means, and the electrical connection means is configured to connect the contact means to an external device, preferably by at least one connecting cable. In other words, the electrical connector advantageously allows an electrical connection from the contact means to an external device to be established by at least one metal cable when in use.

[0028] In a specific embodiment, the electrical connection means is a metal element and is in direct contact with the contact means. The electrical connection means preferably comprises a metal element, and a pin and / or a through element passing through the metal element of the electrical connection means and accommodated in the contact means, thereby allowing direct contact between these metal elements and the contact means.

[0029] In a particular embodiment, the electrical connector further comprises an actuation device configured for actuating the contact device, said actuation device being accommodated in the inner housing and oriented according to the longitudinal direction XX′.

[0030] Thus, the actuating device and the contacting device are positioned adjacent to each other and in contact with each other. In other words, according to this configuration, the actuating device serves as a push platform for the contacting device, wherein the positioning of the contacting device is thereby advantageously improved.

[0031] In a particular embodiment, the actuating means comprises at least one protruding element in contact with the contact means. In a particular embodiment, the at least one protruding element of the actuating means is partially accommodated at one end of the contact means.

[0032] The actuating device is housed in an inner housing of the body of the electrical connector. In a particular embodiment, the actuating device is supported by one of its ends on one end of the inner housing, wherein the opposite end comprises at least one protruding element in direct contact with the contact device. Thus, the attachment of the actuating device and the contact device is oriented according to the longitudinal direction XX' towards the opening of the second end, wherein the contact device is thus arranged closer to said opening in the inner housing of the body.

[0033] In a particular embodiment, the actuating device is an integral part of the body of the electrical connector. Advantageously, this allows a reinforced configuration of both the body and the actuating device, which configuration has a stronger support in its structure, which configuration is integrated in the inner housing of the electrical connector.

[0034] In a particular embodiment, the actuating device is a separate element positioned in the inner housing of the body of the electrical connector. This allows better adaptability of the position of the actuating device and simpler maintenance, wherein the actuating device can be replaced if necessary.

[0035] A second inventive aspect of the present invention describes an electrical connection system, the electrical connection system comprising:

[0036] a drive belt extending according to a longitudinal direction XX′ and comprising a first end, a second end and a plurality of metal cables arranged between the first end and the second end according to the longitudinal direction XX′,

[0037] - the first electrical connector according to the first inventive aspect, and

[0038] - the second electrical connector according to the first inventive aspect, the second electrical connector comprising an electrical connection device,

[0039] wherein a first end of the drive belt is inserted into the first connector through a corresponding opening of the first connector, and a second end of the belt is inserted into the second connector through a corresponding opening of the second connector,

[0040] The first electrical connector is longitudinally connected to the first end portion through electrical connections between a plurality of metal cables and the connecting device of the first electrical connector according to the longitudinal direction XX'.

[0041] The second connector is longitudinally connected to the second end portion through electrical connections between a plurality of metal cables and the connecting device of the second electrical connector according to the longitudinal direction XX', and

[0042] The second electrical connector is configured to be connected to at least one external device.

[0043] Included in the drive belt are metal cables arranged substantially in parallel along its entire length.

[0044] In a particular embodiment, the metal cable is embedded in a plastic material, preferably a polymer material, which extends along the exterior of said metal cable from the first end to the second end.

[0045] In a particular embodiment, the connection means comprises projections, wherein each projection directly contacts each of the metal cables of the drive belt. In other words, at least one projection of the contact means is pressed into one of the metal cables.

[0046] Advantageously, the present system allows electrical connection of both connectors to the metal cables of the drive belt in a longitudinal direction, thereby allowing a direct and more efficient connection.

[0047] Furthermore, the present system and the configuration of its electrical connectors positioned so that the electrical connection is established according to the longitudinal direction XX' allow a reduction in the space required to assemble connections having these characteristics, as well as greater accessibility for maintenance and / or replacement operations both for either of the two connectors and for the drive belt of the system.

[0048] In a specific embodiment, at least one of the first and second electrical connectors includes a fastening device configured to fix the drive band in a predetermined position when the drive band is inserted through the opening. Advantageously, this allows the position of the drive band to be fixed relative to the inner housing of the body of the connector.

[0049] In a particular embodiment, the fastening means are oriented according to a longitudinal direction XX'.

[0050] In a particular embodiment, the fastening means are oriented according to a direction transverse to the longitudinal direction XX′.

[0051] In a specific embodiment, the fastening means is selected from one of the following:

[0052] - threaded attachments and / or riveted attachments,

[0053] -pin,

[0054] - adhesives,

[0055] -Toe clips, or

[0056] - Cam.

[0057] In a particular embodiment, at least one of the electrical connectors is constructed in two parts, the electrical connector further comprising attachment means, preferably a threaded attachment, configured for attaching the parts of the electrical connector to each other.

[0058] In a particular embodiment, the attachment means are oriented according to a longitudinal direction XX'.

[0059] In a particular embodiment, the attachment means are located on opposite sides of the periphery of the body of the electrical connector.

[0060] In a particular embodiment, the attachment means are configured for bringing the contact means of the electrical connector closer to the plurality of metal cables of the drive belt according to the longitudinal direction XX′ by means of the actuation means.

[0061] Advantageously, this allows ensuring electrical contact between the contact device and the plurality of metal cables of the drive belt, thereby in turn fixing the relative position of the contact device relative to each of the metal cables of the drive belt. In addition, the proximity of the contact device to the plurality of metal cables of the drive belt allows a simpler assembly of the system.

[0062] In a particular embodiment, each protrusion of the contact device is electrically connected to a metal cable of the drive belt.

[0063] In a particular embodiment, each protrusion of the contact device is electrically connected to at least two metal cables of the drive belt. In a particular embodiment, two or more metal cables of the drive belt are associated.

[0064] In a specific embodiment, the electrical connection means are connected to two corresponding ends of the contact means in a direction transverse to the longitudinal direction XX', preferably to protrusions at the two ends of the contact means and to a connecting cable. Advantageously, this allows reducing the space required for the electrical connection to at least one external device.

[0065] In addition, the third and fourth invention aspects relate to a method for assembling an electrical connection system, such as the electrical connection system involved in the second invention aspect, and a method for measuring wear and / or breakage of a drive belt with the aid of an electrical connection system, such as the electrical connection system involved in the second invention aspect.

[0066] Specifically, in a specific embodiment, an electrical connection system, such as the electrical connection system involved in the second invention aspect, can be obtained from the following assembly sequence:

[0067] a) inserting a first end of the drive belt through an opening of the first electrical connector and inserting a second end of the drive belt through an opening of the second electrical connector, and

[0068] b) Connecting the contact devices of the first electrical connector and the second electrical connector to a plurality of metal cables of the drive belt respectively.

[0069] Additionally, step a) may also include the act of fixing the position of the first and second ends of the drive belt to the respective electrical connectors by means of attachment means, as indicated above.

[0070] In connection with a method for measuring wear and / or breakage of a drive belt, an analysis of the state of the drive belt can be performed with the aid of an electrical connection system, such as that involved in the second inventive aspect. For this purpose, in addition to the electrical connection system, at least one external device including a controller is provided.

[0071] In this way and according to a specific embodiment, the method for measuring the wear and / or breakage of at least one metal cable of a drive belt can be performed according to the following sequence:

[0072] a) Connect the electrical connection system to external equipment,

[0073] b) collecting, by means of a controller of an external device, data on electrical connections existing between the contact means of the first electrical connector and the second electrical connector, respectively, and a plurality of metal cables of the drive belt, and

[0074] c) Measuring the wear and / or breakage of at least one metal cable of the drive belt from the data collected in step b).

[0076] In a specific embodiment, step a) is performed by electrical connection of at least one electrical connector to an external device.

[0077] Furthermore, the method for measuring the wear and / or breakage of at least one metal cable of a drive belt comprises an additional step, wherein the additional step is a step d) of determining the risk of breakage of the drive belt based on the measurements performed in step c) for the purpose of making a suitable decision regarding the maintenance or repair of said drive belt.

[0087] Features of specific embodiments of the present invention are described based on the current drawings.

[0088] Figure 1A and Figure 1B An exemplary embodiment of the electrical connector 1 according to the first aspect of the present invention is shown, and Figure 1C and Figure 1D A second exemplary embodiment of the electrical connector 1 according to the first aspect of the invention is shown.

[0089] As shown in said figures, the electrical connector 1 comprises a body 1.1 which, in this case, is divided into two parts which allow them to be assembled and fixed to each other to form the body 1.1 of said electrical connector 1. This body 1.1 and therefore the electrical connector 1 extends according to a main direction, in particular a longitudinal direction XX'.

[0090] The parts of the body 1.1 are fixed to each other by means of attachment means 1.9, which in this case are bolts, in particular anchor screws, which extend longitudinally according to the longitudinal direction XX' and allow the parts of the body 1.1 to be brought closer in place and to fix the parts of the body 1.1 to each other. The attachment means 1.9 may also be attached by snap-fit ​​and / or riveting. Figure 1A and Figure 1B In this case, the attachment means 1.9 are located on two opposite faces of the periphery of the body 1.1, adjacent to the ends of the respective means of contacting the means 1.5. Figure 1C and Figure 1DIn this case, the attachment means 1.9 are located on two opposite faces of the periphery of the body 1.1 in a direction transverse to the direction in which the contact means 1.5 extend.

[0091] When the parts of the body 1 .1 are assembled, the body 1 .1 comprises an inner casing 1 .2, the body 1 .1 being thus partially hollow.

[0092] according to Figure 1A The electrical connector 1 is limited by a first end 1.4 and a second end 1.3, each of which corresponds to the end of one of the parts of the body 1.1. In addition, one of the parts of the body 1.1 includes an opening 1.1.1 for accommodating and fixing the drive belt 2.1, the opening 1.1.1 is preferably a rectangular opening. The opening 1.1.1 is located at the second end 1.3 of the electrical connector 1 and allows access to the inner housing 1.2 from the outside of the body 1.1 of the electrical connector 1.

[0093] Figure 1B The inner housing 1 .2 is shown, in which in turn an actuating device 1 .6 is accommodated, wherein a contact device 1 .5 is arranged on the actuating device 1 .6 , said contact device 1 .5 also being accommodated inside the inner housing 1 .2 of the body 1 .1 .

[0094] The contact device 1 .5 in turn comprises a plurality of protrusions 1 .5.1 oriented according to a longitudinal direction XX' towards the opening 1 .1 .1 at the second end 1 .4 of the body 1 .1 .

[0095] When the electrical connector 1 is used, the protrusion 1.5.1 allows electrical connection with the metal wire of the drive belt 2.1, thereby constructing an electrical circuit.

[0096] When the electrical connector 1 is used, the actuating device 1.6 allows the position of the contact device 1.5 and therefore the plurality of protrusions 1.5.1 in the longitudinal direction XX' to be modified and fixed, so that the contact device 1.5 becomes closer to the end of the drive belt 2.1 to cause electrical contact between the plurality of protrusions 1.5.1 and the metal wire embedded in the drive belt 2.1, thereby constructing a circuit.

[0097] In a specific embodiment, the electrical connector 1 comprises an electrical connection device 1.7 which is connected at one end to the contact device 1.5 and at the opposite end by means of a Figure 1A At least one connecting cable C shown in FIG. 1 is connected to an external device E.

[0098] Thus, the electrical connection means 1.7 allow electrical connection of the contact means 1.5 with an external device E allowing measurement of electrical data, in this case collected by the plurality of protrusions 1.5.1 when they are in contact with the metal wires of the drive belt 2.1.

[0099] like Figure 1A As shown in , the electrical connection device 1.7 is constructed by means of a portion that allows the accommodation of the end of a metallic connection cable C and the electrical connection of the end of the metallic connection cable C with a contact device 1.5 that is also metallic. The portion that accommodates and connects the end of the connection cable C is fixed to the contact device 1.5 by attachment means such as screws or pins, thereby allowing all parts of the electrical connection device 1.7 to be in electrical contact with the contact device 1.5.

[0100] Furthermore, the electrical connector 1 comprises in its body 1 .1 a housing for driving the fastening means 1 .8 of the strap 2 .1 when the electrical connector 1 is in use.

[0101] A second aspect of the present invention relates to an electrical connection system 2, the specific implementation of which is as follows: Figure 2A , Figure 2B , Figure 3A and Figure 3B Shown in.

[0102] Specifically, Figure 2A An electrical connection system 2 constructed by a first electrical connector 1 and a second electrical connector 1 is shown. Figure 2B A second example of an electrical connection system 2 is shown.

[0103] In this case, as can be observed, the second electrical connector 1 comprises electrical connection means 1.7, whereas the first electrical connector 1 does not have said electrical connection means 1.7. Thus, the second electrical connector 1 can be connected to one or more external devices via one or more connection cables C through said electrical connection means 1.7.

[0104] Specifically, the electrical connection device 1.7 is respectively connected to the protrusions 1.5.1 located at two corresponding ends of the contact device 1.5, that is, connected to the protrusions located at two ends of the contact device 1.5 and to the connection cable C, which is in turn connected to the corresponding external device E.

[0105] The electrical connection system 2 further comprises a drive belt 2.1 extending in the longitudinal direction XX'. The drive belt 2.1 comprises a first end 2.1.1 and a second end 2.1.2 fixed to the first electrical connector 1 and the second electrical connector 1 respectively. Specifically, as Figure 3AAs shown in the cross section of the first and second ends 2.1.1, 2.1.2 are introduced through the openings 1.1.1 of the first and second electrical connectors 1, 1, respectively, so that the first and second ends 2.1.1, 2.1.2 of the drive belt 2.1 are accommodated in the inner housings 1.2 of the first and second electrical connectors 1, 1. In the technical field of lifts / elevators, the first and second ends 2.1.1, 2.1.2 of the drive belt 2.1 are referred to as end A and end B of the drive belt, wherein end A corresponds to the end associated with the first connector 1 comprising the electrical connection means 1.7, and end B corresponds to the end associated with the second connector 1.

[0106] Specifically, Figure 2A and Figure 2B as well as Figure 3A and Figure 3B As shown in FIG. 1 , the drive belt 2.1 is fitted in the first electrical connector 1 and the second electrical connector 1 through the opening 1.1.1, wherein the position of the drive belt 2.1 is fixed by the fastening device 1.8.

[0107] Figure 1B The fastening means 1.8 is a set screw cooperating with a through opening made in the body 1.1 of the electrical connector 1 and oriented perpendicularly to the direction in which the contact means 1.5 extend.

[0108] Figure 1D The fastening means 1.8 are through screws oriented in a direction transverse to the direction in which the contact means 1.5 extend.

[0109] The position in which the drive belt 2.1 remains fixed is a predetermined position, wherein the predetermined position is a position appropriately close to the first end 2.1.1 or the second end 2.1.2 relative to the first electrical connector 1 and the second electrical connector 1.

[0110] Figure 3B A cross-sectional view of a first end 2.1.1 and a second end 2.1.2 of a drive belt 2.1 is shown, observing a plurality of metal cables 2.1.3 in the form of metal wires extending along a longitudinal direction XX and embedded in the drive belt 2.1. This situation shows how the metal cables 2.1.3 are evenly distributed along the cross section of the drive belt 2.1, wherein each of the metal cables 2.1.3 is a bundle of metal wires.

[0111] Figure 3A and Figure 3B The components of the electrical connection system 2 are shown when the drive strip 2 . 1 has been introduced into the first electrical connector 1 and the second electrical connector 1 and the position of the connectors has been fixed.

[0112] This case shows how a plurality of protrusions 1 .5.1 contact the metal cables 2.1 .3 of the drive belt 2.1 in the longitudinal direction XX'.

[0113] Thereby, the contact device 1.5 of the first electrical connector 1 electrically contacts the metal cable 2.1.3 from the first end 2.1.1 of the drive strip 2.1, while the contact device 1.5 of the second electrical connector 1 electrically contacts the metal cable 2.1.3 from the second end 2.1.2 of the drive strip 2.1.

[0114] In addition to providing a simpler configuration, this electrical contact in the longitudinal direction allows better access to the metal cable 2.1.3 of the drive strip 2.1 from the first end 2.1.1 and the second end 2.1.2 of the drive strip 2.1. Likewise, given that the protrusion 1.5.1 of the contact device 1.5 is housed inside each electrical connector 1 without being exposed or having to be embedded in the material forming the drive strip 2.1, the contact between the protrusion 1.5.1 and the metal cable 2.1.3 is therefore more direct and uniform, and this configuration of electrical connection is also safer.

[0115] Furthermore, the actuating device 1.6 allows the contact device 1.5 to be moved in the longitudinal direction XX' so that the protrusion 1.5.1 of said contact device 1.5 is brought closer to the metal cable 2.1.3 of the first end 2.1.1 or the second end 2.1.1 of the drive belt 2.1 respectively by means of the actuating device 1.6.

[0116] These electrical connections can be made based on different configurations. In the simplest exemplary embodiment, the connection of the two end protrusions 1.5.1 of the contact device 1.5 with the end metal cables 2.1.3 of the drive belt 2.1 and the electrical connection of the middle protrusion 1.5.1 with the middle metal cable 2.1.3 of the drive belt 2.1 are both made in the first connector 1 and the second connector 1.

[0117] In another exemplary embodiment, each protrusion 1.5.1 of the contact device 1.5 is electrically connected to a single metal cable 2.1.3 of the drive belt 2.1, wherein all protrusions 1.5.1 are thereby electrically connected to a single metal cable 2.1.3 of the available metal cables in the drive belt, or vice versa and wherein all metal cables 2.1.3 of the drive belt are electrically connected to a single protrusion 1.5.1 of the available plurality of protrusions in the contact device.

[0118] In another exemplary embodiment, each protrusion 1.5.1 of the contact device 1.5 is electrically connected to two associated metal cables 2.1.3 of the drive belt 2.1. In other words, each protrusion 1.5.1 is connected to two adjacent metal cables 2.1.3, while no one and the same metal cable 2.1.3 is connected to more than one protrusion 1.5.1. Therefore, each pair of metal cables 2.1.3 is a connection diagram between metal wires that allows each pair of metal cables 2.1.3 of the pair to be short-circuited in the circuit.

[0119] Any of these configurations provides a closed circuit, wherein the drive belt 2.1 is connected to an external device E via the second connector 1 for measuring various parameters, preferably wear and / or breakage, while the first connector 1 allows the circuit to be closed by connecting the first connector 1 to the opposite end of the drive belt 2.1.
