Description
[0001] The invention relates to a sealing grommet for a motor vehicle according to the preamble of claim 1. Furthermore, the invention relates to an arrangement of a sealing grommet in an opening of a component for a motor vehicle according to the preamble of claim 7.
[0002] EP 1 617 517 B1 discloses an electrically conductive connection between a cable end made of an electrically conductive metal, which has a terminal end and tabs for connecting, and a cable end which has a conductor section and an insulation section with an outer surface, wherein a sealing sleeve is provided which seals between a sleeve and an outer surface of an insulation section of the cable end.
[0003] The object of the invention is to provide a sealing grommet for a motor vehicle and an arrangement of a sealing grommet in an opening of a component for a motor vehicle, so that the signal transmission quality between two components of the motor vehicle can be particularly improved.
[0004] This problem is solved according to the invention by a sealing grommet for a motor vehicle with the features of claim 1 and by an arrangement of a sealing grommet in an opening of a component for a motor vehicle with the features of claim 7. Advantageous embodiments of the invention are the subject of the dependent claims and the description.
[0005] A first aspect of the invention relates to a sealing grommet for a motor vehicle, which is designed, for example, as a motor vehicle, in particular as a passenger car or as a commercial vehicle. Preferably, the motor vehicle, particularly in its fully manufactured state, has the sealing grommet.
[0006] The sealing sleeve has at least one contact area by which the sealing sleeve, which is to be arranged or is arranged in an opening of a component of the motor vehicle, can be arranged, in particular directly, on a wall of the component that defines or forms the opening, especially in the radial direction of the opening. In other words, the sealing sleeve is designed to be at least partially received or arranged in the opening of the component. When the sealing sleeve is at least partially received or arranged in the opening, it rests against the wall via the contact area, for example, directly. This means that the sealing sleeve can be supported or is supported, in particular in a sealing or sealing manner, on the wall of the component via the contact area, especially in the radial direction of the sealing sleeve to the outside.The component is, for example, a body part of the motor vehicle or another component of the motor vehicle. The sealing grommet and the component are designed separately. The contact area of the sealing grommet is preferably located on an outer surface of the sealing grommet. This means that the contact area is formed by an outer surface of the sealing grommet that points outwards, particularly in the radial direction of the sealing grommet.
[0007] The opening is designed, for example, to allow the passage of at least one conductor element, particularly one carrying data, such as electrical and / or optical components. The sealing grommet is specifically designed to seal the opening while simultaneously allowing the conductor element to pass through it, thus enabling the conductor element to be passed through the component or its opening via the sealing grommet. The sealing grommet can therefore serve to seal the passage of cables or conductors through the opening or the component and to protect the cables or conductors from external influences such as moisture, dust, and / or mechanical stress.
[0008] To significantly improve signal transmission quality between at least two components of the motor vehicle, the invention provides that the sealing grommet has at least two feed-through channels designed to receive a respective conductor, in particular a data-transmitting electrical and / or optical conductor. This means that the respective conductor can be received or held in the respective feed-through channel. In other words, the respective conductor can be inserted into the respective feed-through channel. Thus, the respective conductor received in the respective feed-through channel is located at least partially within the sealing grommet. In this context, the term "respective feed-through channel" can be understood as a respective cavity, in particular one extending within the sealing grommet.The feedthrough channels allow conductors to be routed, at least partially, through the sealing grommets for connecting two vehicle components, particularly for data transmission, electrically and / or optically. This means that the respective conductor can be received or held in the feedthrough channel to be guided through the sealing grommet, specifically to connect the aforementioned components. In other words, the feedthrough channel is designed to allow the conductor to pass through the sealing grommet. The feedthrough channels are helical in shape. This means that each feedthrough channel has a helical or helical form.In other words, the respective feedthrough channel is shaped according to a helix. The helix, which can also be described as a screw, helical, cylindrical spiral, or helical, can be understood here as a curve, particularly with a constant pitch, around the surface of a cylinder, especially an imaginary one. The curve can wind around the surface of the cylinder with a constant pitch. Consequently, the helical shape can be understood as a form corresponding to a helical or cylindrical spiral.
[0009] The respective conductor is, for example, a single wire, particularly of the conductor element. The single wire can also be referred to as a cable core. The conductor element can therefore be a cable consisting of at least two individual wires in the form of the aforementioned cores or conductors. The conductors or cores can be twisted together. The conductors are, for example, made of metal. For example, the respective conductor is a single wire, insulated or uninsulated. Thus, the conductor element is, for example, a twisted pair. The components are, for example, arranged on opposite sides of the component, particularly the opening, whereby connecting the components may necessitate the passage of the conductor through the component, particularly through the opening.In this context, "each component" refers to a specific electrical and / or electronic component. For example, at least one component may be an electronic computing device, such as a control unit. The other component may be a sensor element. Particularly when one or both components are configured as electronic computing devices, the components can be connected to each other via the conductors and the sealing sleeve for data transmission.
[0010] The invention is based in particular on the following findings and considerations: The current state of the art for sealing grommets, which can be used to seal openings, offers a multitude of configurations that can vary depending on the application. Such sealing grommets can primarily serve to seal the passage of cables or conduits and protect them from external influences such as moisture, dust, or mechanical stress. Sealing grommets are available in various designs adapted to the specific requirements of different areas of application. For example, such sealing grommets can be manufactured in different sizes, shapes, and materials, depending on the application requirements.A conventional grommet, also known as a standard grommet, can be equipped with a single hole, allowing a single sheathed cable to pass through. Alternatively, such a conventional grommet can also have multiple holes, enabling the passage of several wire pairs or single wires. However, conventional grommets always have parallel openings or holes. In an attempt to guide twisted single wires through a conventional grommet, the cable containing the single wires had to be partially untwisted. After passing the wires through, an attempt was made to partially untwist the cable, that is, to return it to its original twisted state.Surprisingly, it was noticed that some force was being transferred to the sealing grommet, preventing the cable or conductors from being guided through it centrally. Furthermore, time domain reflectometry (TDR) revealed an impedance deviation of over 10 ohms. This indicates that the TDR measurement showed that the subsequent untwisting of the conductors, or their off-center insertion through the grommet, was causing the impedance deviation. By twisting the cable as close as possible to the sealing inlet of the grommet, the impedance can return to a normal range, which might be, for example, 100 ± 3 ohms.A disadvantage of conventional sealing grommets is that twisted conductors require a greater degree of untwisting, meaning the wires must be guided parallel through the grommet or into the connector. This can make the conductors passing through the grommet, or the connector itself, more susceptible to external electromagnetic interference. Furthermore, the stability of any remaining twists in the conductors may be compromised. This can lead to further unraveling of the conductors. If the twisting is then performed manually, it can place a particularly high mechanical load on the conductors, potentially forcing them against the grommet or its inner wall on one side.This can cause a reduction in the tightness of the sealing grommet on the opposite side.
[0011] In contrast, the aforementioned disadvantages can be overcome particularly advantageously by means of the sealing grommet according to the invention. A key feature of the invention is that the sealing grommet has a spiral-shaped inner recess in the form of the respective feed-through channel. The conductor element, also referred to as a cable, can be guided through the sealing grommet in a helical shape via this inner recess, thus preserving the twist of the conductor element or the twisting of the conductors. This significantly improves signal quality. Furthermore, by preserving the twist, for example through an angled design, mechanical stresses can be minimized, thereby protecting signal quality.Twisting the conductors is often necessary to ensure signal transmission quality in electrical cables and to minimize crosstalk between individual conductors. A helical guide for each conductor within the grommet, created by the feedthrough channel, allows the conductors to retain their twist. In other words, the twist is maintained, which also serves as protection against untwisting. Furthermore, a tight seal is ensured despite the twisted arrangement. Since re-twisting is unnecessary, the mechanical influence caused by this process is either eliminated or significantly reduced. In differential connector systems, this can have a positive effect on the TDR (Total Dielectric Strength) with regard to the connector system's impedance.
[0012] In a further embodiment, it is provided that one, in particular each, central axis of the helical feedthrough channels extends at least substantially in the axial direction of the sealing sleeve. In other words, the central axis of the helical feedthrough channels and the axial direction of the sealing sleeve run parallel to each other. This allows the twisting of the conductor to be maintained particularly well. The central axis, which can also be referred to as the helix axis or screw axis, can be understood here as an axis around which the helical shape or the respective feedthrough channel winds. The central axis is thus an axis of the helix.
[0013] In a further embodiment, the feedthrough channels are arranged coaxially. In other words, the central axes of the feedthrough channels are congruent, specifically identical. This means that the feedthrough channels are twisted together, i.e., arranged in a twisted configuration relative to each other. Thus, a multi-start, particularly a double-start, helix or helical shape can be provided within the sealing sleeve, where a first start can be formed by a first of the feedthrough channels and a second start can be formed by the second of the feedthrough channels. The feedthrough channels can therefore form a multi-start, particularly a double-start, screw or helix. Because the feedthrough channels are arranged coaxially, the twisting of the conductors can be maintained particularly well within the sealing sleeve.
[0014] For example, it is intended that the sealing sleeve is designed, at least partially, and in particular predominantly or entirely, as a rubber sleeve. In other words, one material of the sealing sleeve is rubber. This allows for a particularly good sealing effect to be achieved with the sealing sleeve. Furthermore, the manufacturing effort for the sealing sleeve can be kept to a minimum.
[0015] In a further embodiment, the sealing sleeve is provided with an inlet opening on one of its inlet sides for inserting the conductor into the respective feedthrough channel. This means that the conductor can be inserted, or is inserted, through the inlet opening for placement in the feedthrough channel, with the inlet opening extending along the inlet side of the sealing sleeve. The respective inlet opening can also be referred to as the respective inlet area. The inlet side is, for example, an axial end face of the sealing sleeve. The axial direction of each inlet opening extends obliquely to the axial direction of the sealing sleeve. In other words, the conductor can be inserted into the respective feedthrough channel via the respective inlet opening at an angle to the axial direction of the sealing sleeve.The respective inlet opening, that is, the respective insertion holes into the respective helical structure, can thus be angled, particularly slightly angled, to reduce mechanical influence on the conductors when inserting them into the sealing sleeve. This prevents mechanical stress that could damage the conductors. This means that protection against damage is significantly increased. The components can therefore be connected to each other with particular security. In particular, this can significantly improve signal transmission quality.
[0016] The respective inlet opening is, for example, bounded by a surface, in particular the outer surface, of the sealing sleeve located on the inlet side, to which the respective axial direction of the respective inlet opening extends obliquely. This means that the surface located on the inlet side has or forms the inlet opening, with the respective axial direction of the respective inlet opening being oblique to this surface, i.e., not perpendicular to this surface. In other words, the respective conductor can be inserted through the respective inlet opening obliquely to the surface located on the inlet side and bounding the inlet opening.
[0017] In a further embodiment, the sealing sleeve has an outlet opening on its outlet side for leading out at least a portion of the conductor contained or arranged in the respective feedthrough channel. This means that at least a portion of the conductor in the respective feedthrough channel can be removed from the sealing sleeve via the outlet opening, which extends on the outlet side. The respective outlet opening can also be referred to as the outlet area. Thus, the respective feedthrough channel can be connected to the surroundings of the sealing sleeve via the respective inlet and outlet openings. In other words, the respective feedthrough channel opens into the surroundings via the respective inlet and outlet openings.Preferably, the axial direction of each outlet opening extends obliquely to the axial direction of the sealing sleeve. This means that the outlet opening is arranged obliquely, and in particular not perpendicularly, to the axial direction of the sealing sleeve. In other words, the outlet opening is designed to guide the conductor obliquely out of the feedthrough channel relative to the axial direction of the sealing element. The outlet opening, which can also be referred to as the exit hole, can thus be slightly angled to reduce the mechanical impact on the conductor as it passes through or exits the sealing sleeve. This effectively prevents damage to the conductor and significantly increases its resistance to damage.This can also improve the signal transmission quality in particular.
[0018] The respective outlet opening is, for example, bounded or formed by a surface located on the outlet side, which can also be referred to as the second surface. In other words, the surface located on the outlet side comprises the outlet opening. The second surface is, for example, an axial end face, particularly an outer end face, of the sealing sleeve. Thus, the outlet side can be an end face of the sealing sleeve. The inlet side and the outlet side are located on different sides of the sealing sleeve, in particular, on opposite sides. The axial direction of the respective outlet opening extends obliquely to the surface located on the outlet side. This means that the respective outlet opening is located obliquely, and in particular not perpendicularly, to the second surface.
[0019] A second aspect of the invention relates to an arrangement of a sealing grommet in an opening of a component for a motor vehicle or of the motor vehicle itself. The sealing grommet is preferably a sealing grommet according to the first aspect of the invention. Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention, and vice versa.
[0020] The sealing sleeve has at least one contact area over which the sealing sleeve is arranged on a wall of the component that limits or forms the opening of the component.
[0021] To particularly improve signal transmission quality between at least two components of the motor vehicle, the invention provides that the sealing sleeve has two feed-through channels designed to receive a respective conductor, through which the conductors for connecting the two components can be or are guided through the sealing sleeve, wherein the feed-through channels are helically shaped. This allows the conductors to be guided helically or spirally through the sealing sleeve, thereby enabling the conductors to retain a twist.
[0022] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or on their own.
[0023] The invention will now be explained in more detail with reference to a preferred embodiment and the drawings. The drawings show: Fig. 1 a schematic perspective view of a sealing sleeve according to the invention; Fig. 2 a particularly schematic representation of a component in whose opening a sealing sleeve according to the invention can be arranged; and Fig. 3 a schematic top view of a sealing sleeve according to the invention in a further embodiment.
[0024] In the figures, identical or functionally equivalent elements are provided with the same reference symbols.
[0025] Fig. Figure 1 shows a schematic perspective view of a sealing grommet 1 for a motor vehicle. The sealing grommet 1 can also simply be referred to as a grommet. The sealing grommet 1 is designed for placement in an opening 2, in particular a through-opening, of a component 3 of the motor vehicle. The component 3 is located in Fig. Figure 2 shows a particularly schematic representation. To arrange the sealing sleeve 1 in the opening 2, in particular to seal the component 3, that is, in particular to seal the sealing sleeve 1 arranged in the opening 2 against the component 3, the sealing sleeve 1 has at least one contact area 4 over which the sealing sleeve 1, to be arranged or already arranged in the opening 2 of the component 3, can be arranged or is arranged on at least one wall 5 of the component 3 that bounds the opening 2. The contact area 4 can be formed by an outer surface of the sealing sleeve 1. The sealing sleeve 1 can have a round or a square, in particular rectangular, cross-section. In the figure shown in Figure 2, the sealing sleeve 1 has at least one contact area 4 over which the sealing sleeve 1, to be arranged or already arranged in the opening 2 of the component 3, can be arranged or is arranged on at least one wall 5 of the component 3 that bounds the opening 2. The contact area 4 can be formed by an outer surface of the sealing sleeve 1. The sealing sleeve 1 can have a round or a square, in particular rectangular, cross-section. Fig. In the embodiment shown in Figure 1, the sealing sleeve 1 has a rectangular cross-section.
[0026] The sealing grommet 1 has two feedthrough channels 8 and 9, each designed to receive a conductor 6 or 7, respectively. This means that the first feedthrough channel 8 is designed to receive the first conductor 6, and the second feedthrough channel is designed to receive the second conductor 7. The conductors 6 and 7 can be passed through the sealing grommet 1 via the feedthrough channels 8 and 9 to connect two components of the motor vehicle. This means that the first conductor 6 can be passed through the sealing grommet 1 via the first feedthrough channel 8, and the second conductor 7 can be passed through the sealing grommet 1 via the second feedthrough channel 9, in order to connect the components. The conductors 6 and 7 are designed to transmit at least one piece of information.Thus, the components for transmitting at least one piece of information via conductors 6 and 7 can be connected to each other. In the exemplary embodiment, conductors 6 and 7 are cores of a twin-core cable element. The conductors 6 and 7 are twisted together, particularly outside the sealing sleeve 1.
[0027] In the Fig. In the embodiment shown in Figure 1, the sealing sleeve 1 has a base body 10, which can also be referred to as the sealing sleeve body. For example, the base body 10 has the contact area 4. In this case, the base body 10 is hollow, whereby the feedthrough channels 8, 9 are formed as hollow channels in the base body 10. This means that the respective feedthrough channel 8, 9 is formed by a respective cavity extending within the base body 10. Thus, the respective feedthrough channel 8, 9 is bounded or formed by the base body 10, in particular by a respective inner surface of the base body 10, for example in its respective radial direction. Fig. Figure 1 shows the sealing sleeve 1 partially transparent, making the feedthrough channels 8, 9 running inside the sealing sleeve 1 visible.
[0028] To significantly improve signal transmission quality between the components, particularly for information transmission, the feedthrough channels 8, 9 are designed with a helical shape. This means that each conductor 6, 7 is guided helically within the sealing grommet 1. This allows each conductor 6, 7 to be arranged helically within its respective feedthrough channel 8, 9, resulting in a helical shape. The sealing grommet 1 thus contains an internal recess resembling a spiral spring in the form of the feedthrough channel 8, 9. This structure enables a cable passing through the sealing grommet 1 to be guided in a helical shape within the grommet 1.This allows the conductors 6, 7, in particular individual wires or wire pairs, to retain their twist even when passing through the sealing sleeve 1, especially through the base body. This significantly improves the signal transmission quality between the components, as untwisting of the conductors 6, 7 within the sealing sleeve 1 is avoided. Furthermore, damage to the conductors 6, 7 is prevented, as manual untwisting of the conductors 6, 7 is unnecessary.
[0029] As in Fig. As shown in Figure 1, in this embodiment, a central axis 11 of the helical passage channels 8, 9 extends in the axial direction 12 of the sealing sleeve 1. The passage channels 8, 9 are arranged coaxially with each other. This means that the passage channels 8, 9 are twisted relative to each other, or intertwined, about the central axis 11, which is particularly common. This allows the conductors 6, 7 to also be guided through the sealing sleeve 1 in a twisted position. For example, the central axis 11 is arranged coaxially with a central axis 11 of the opening 2. The central axis 11 runs in the axial direction of the opening 2, which can also be referred to as a bore. Thus, it is particularly intended that the axial direction 12 of the sealing sleeve 1 runs parallel to the axial direction, or central axis 11, of the opening 2.
[0030] Preferably, each feedthrough channel 8, 9, that is, each helix according to which the respective feedthrough channel 8, 9 is shaped, revolves around the central axis 11 multiple times. This means that the respective helix or helix shape has several turns. Thus, each pitch of the respective helix or helix shape is preferably less than or equal to half the length of the sealing sleeve 1, in particular of the base body 10, in the axial direction 12.
[0031] In this case, the sealing grommet 1 is designed as a rubber grommet. Thus, for example, the base body 10 is made of rubber. Therefore, a seal against capillary action can be achieved for twisted conductors by means of a helical rubber grommet.
[0032] In this embodiment, the sealing sleeve 1 has an inlet side 14 and an outlet side 15 that differs from the inlet side 14. A first surface 16, which can also be referred to as the first surface 16, is arranged on the inlet side 14. A surface 17, which can also be referred to as the second surface 17, is arranged on the outlet side 15. The surfaces 16 and 17 face away from each other. The surfaces 16 and 17 extend, for example, obliquely or perpendicularly to the contact area 4. In this embodiment, the first surface is arranged at one end on the sealing sleeve 1, in particular on the base body 10, in the axial direction 12 of the sealing sleeve 1, and the second surface 17 is arranged at the other end on the sealing sleeve 1, in particular on the base body 10, in the axial direction 12 of the sealing sleeve 1.
[0033] The sealing grommet 1 has two inlet openings 18, 19, which are arranged on the inlet side 14 and are bounded or formed by the first surface 16. Each inlet opening 18, 19 is designed for inserting the respective conductor 6, 7 into the respective feedthrough channel 8, 9. This means that the first conductor 6 can be inserted, or is inserted, into the first feedthrough channel 8 via the first of the inlet openings 18, and that the second conductor 7 can be inserted, or is inserted, into the second feedthrough channel 9 via the second of the inlet openings 19.
[0034] Furthermore, the sealing sleeve 1 has two in Fig. One non-visible outlet opening 20, 21 is provided. The outlet openings 20, 21 are arranged on the outlet side 15 and are bounded or formed by the second surface 17. The respective outlet opening 20, 21 is provided for leading out at least a portion of the respective conductor 6, 7 received in the respective feedthrough channel 8, 9 from the sealing grommet 1. This means that at least a portion of the conductor 6 received in the first feedthrough channel 8 can be led out of the first feedthrough channel 8, and thus in particular out of the sealing grommet 1, via a first of the outlet openings 20, and that at least a portion of the second conductor 7 received in the second feedthrough channel 9 can be led out of the second feedthrough channel 9, and thus in particular out of the sealing grommet 1, via the second of the outlet openings 21.
[0035] In the exemplary embodiment, it is provided that a respective axial direction 22, 23 of the respective inlet opening 18, 19 extends obliquely to the axial direction 12, in particular obliquely to the first surface 16, and that a respective axial direction 24, 25 of the respective outlet opening 20, 21 extends obliquely to the axial direction 12, in particular obliquely to the second surface 17. Thus, an oblique inlet for the respective conductor 6, 7 and an oblique outlet for the respective conductor 6, 7 can be achieved. Extending the oblique direction relative to the axial direction 12 is, for example, particularly advantageous in Fig. Figure 3 shows the sealing sleeve 1 according to a further embodiment. Here, the axial direction 22 is the axial direction 22 of the first inlet opening 18, and the axial direction 23 is the axial direction 23 of the second inlet opening 19. Furthermore, the axial direction 24 is the axial direction 24 of the first outlet opening 20, and the axial direction 25 is the axial direction 25 of the second outlet opening 21. The conductors 6, 7 can thus be inserted obliquely into the respective helical structure, i.e., into the respective helical feedthrough channel 8, 9, thereby preventing damage to the respective conductor 6, 7 during insertion. The oblique insertion is shown in Fig. 3. This is illustrated by means of an oblique rectangle 26. Similarly, the conductors 6, 7 can be made obliquely from the helical structure, which also avoids damage.
[0036] In the Fig. In the embodiment shown in Figure 3, the sealing sleeve 1, in particular the base body 10, has at least one positive-locking structure 27 on its outer surface, via which the sealing sleeve 1 can be positively connected to, or is connected to, a positive-locking structure of the component 3 that corresponds to the positive-locking structure 27. The positive-locking structure of the component 3 is located, in particular, in the opening 2. The positive-locking structure 27 has, for example, at least one raised area and / or at least one recessed area, for example, in the form of a groove. The respective raised area or recessed area is preferably designed to correspond to the positive-locking structure of the component 3. This allows for a particularly secure and particularly tight connection.
[0037] Furthermore, in the Fig.In the embodiment shown in Figure 3, the inlet openings 18, 19 are arranged in respective receiving areas 28, 29. This means that the first inlet opening 18 is arranged in a first receiving area 28 and the second inlet opening 19 is arranged in a second receiving area 29. The receiving areas project from the base body 10 in the axial direction 12 of the sealing sleeve 1. For example, the receiving areas 28, 29 are spaced apart from each other. In this example, the outlet openings 20, 21 are arranged in respective receiving areas 30, 31. This means that the first outlet opening 20 is arranged in a third receiving area 30 and the second outlet opening 21 is arranged in a fourth receiving area 31. The receiving areas 30, 31 project from the base body 10 in the axial direction 12 of the sealing sleeve 1. For example, the receiving areas 30, 31 are spaced apart from each other.In this case, the receiving areas 29, 30 are arranged at one end of the base body 10, and the receiving areas 30, 31 are arranged at the other end of the base body 10. The receiving areas 28, 29, 30, 31 allow the conductors 6, 7 to be inserted particularly well into and guided through the feedthrough channels 8, 9, and out of them, especially when the sealing sleeve 1 is already arranged in the opening 2.
[0038] Furthermore, a method for arranging the sealing sleeve 1 in the opening 2 of the component 3, in particular a method for connecting the components, is disclosed. The sealing sleeve 1 can be arranged in the opening 2, particularly via the respective contact area 4, so that the sealing sleeve 1 rests, for example, against the wall 5 within the opening 2 via the contact area 4. Furthermore, the conductors 6, 7 can be guided helically through the sealing sleeve 1 by arranging the respective conductor 6, 7, for example, via the respective inlet opening 18, 19, in the respective feedthrough channel 8, 9, and, for example, via the respective outlet opening 20, 21, through or out of the respective feedthrough channel 8, 9. This allows the conductors 6, 7 to be connected at one end to a first component and at the other end to a second component.
