Description

Technical Field

[0001] This invention relates to the field of building material production technology, and more specifically, to a composite board processing equipment. Background Technology

[0002] In prefabricated concrete buildings, composite slabs, as typical horizontal load-bearing components, are usually composed of a factory-prefabricated base slab and a cast-in-place concrete overlay. Their performance is highly dependent on the collaborative working ability between the prefabricated and cast-in-place layers, which is directly constrained by two key technological aspects: the density of the concrete after pouring and the quality of the surface roughening treatment. Traditional composite slab production often uses attached or platform vibrators for compaction, which suffers from insufficient vibration force, uneven distribution, and difficulty in effectively eliminating internal air bubbles. This easily leads to internal porosity and honeycomb-like surface defects, affecting structural strength and durability. Simultaneously, existing roughening processes rely heavily on manual labor or simple machinery, making it difficult to achieve a controllable roughness surface with consistent depth and uniform texture, thus failing to consistently meet the code requirements for the shear resistance of the composite surface.

[0003] Furthermore, existing processing equipment generally separates the vibration and texturing processes, lacking integrated design. This not only occupies a large space and has a long cycle time, but also allows changes in the initial setting state of the concrete during the waiting period between vibration and texturing to easily affect the texturing effect. Although some equipment attempts to combine pressurization and texturing functions, the problem of synchronous operation in a sealed environment has not been solved, resulting in limited pressurization effect, dust emission, and insufficient texturing accuracy.

[0004] Therefore, there is an urgent need for a composite slab processing equipment that integrates high-efficiency gravity impact vibration, sealing pressure and precise controllable roughening, so as to realize the integrated and automated manufacturing of high-density concrete molding and high-quality composite surface, and improve the overall performance and industrial production level of precast components. Summary of the Invention

[0005] The purpose of this invention is to provide a composite board processing device, which aims to solve the problems mentioned in the background art.

[0006] Based on this, the technical problem to be solved by the present invention is: how to provide a composite slab processing equipment that integrates efficient vibration compaction and controllable surface treatment, which can not only significantly improve the density and surface roughness of concrete, but also ensure the accuracy and stability of steel bar positioning during the production process.

[0007] This invention is implemented as follows: a composite board processing device includes a device base and a device frame fixed thereon, and further includes: An adjustable mold mechanism is provided, wherein a guide post is slidably fitted on the outer side of the adjustable mold mechanism, and the lower end of the guide post is fixed to the equipment base; A vibration excitation mechanism is used to drive the adjustable mold mechanism to rise slowly and then fall rapidly under its own weight, so as to compact the concrete poured inside the adjustable mold mechanism. The pressure roughening mechanism is installed on the equipment frame via a sealed telescopic cylinder. The pressure roughening mechanism is used to seal and pressurize the adjustable mold mechanism and perform controllable roughening operations on the concrete inside the adjustable mold mechanism.

[0008] Optionally, a set of vibration excitation mechanisms is provided on each side of the adjustable mold mechanism. Each set of vibration excitation mechanisms includes two support frames. The lower end of the support frame is fixed to the equipment base. A support cylinder is fixed on the support frame. A rotating shaft is rotatably installed inside the support cylinder. A rotating plate is rotatably connected to the support cylinder. The other end of the rotating plate is hinged to a transmission plate through a first connecting shaft. The other end of the transmission plate is hinged to the outside of the adjustable mold mechanism through a second connecting shaft. The two rotating shafts of the same set of vibration excitation mechanisms are connected by a second transmission assembly. A second motor for driving the rotating shaft is fixed on one of the support frames. A linkage column is fixed on the rotating plate. A lever capable of actuating the linkage column is fixed on the rotating shaft.

[0009] Optionally, the two second connecting shafts of the same set of vibration excitation mechanisms are located at the two outer ends of the adjustable mold mechanism.

[0010] Optionally, the length of the rotating plate between the linkage column and the first connecting shaft is adjustable, and / or the length of the transmission plate is adjustable.

[0011] Optionally, the adjustable mold mechanism includes a base plate, with one guide post at each of the four corners of the base plate; a side mold is provided on the upper side of the base plate, with a rebar positioning groove on the side mold, and an outer frame is slidably fitted on the outer side of the side mold; an adjustable vibration telescopic cylinder is fixed on the base plate, and the telescopic spindle end of the adjustable vibration telescopic cylinder is fixedly connected to the outer frame; a rebar support post is provided on the outer side of the side mold, with end blocks rotatably installed at both ends of the rebar support post, the end blocks being fixed to the outer frame, and a first knob being fixed at the end of the rebar support post.

[0012] Optionally, multiple sets of auxiliary demolding components are fixed to the outside of the side mold. The auxiliary demolding components include a support plate, a fixed support member, a screw, and a second knob. The fixed support member is fixed to the outside of the side mold. A screw is threadedly connected to the fixed support member. A second knob is fixed to the upper end of the screw. The support plate is rotatably installed at the lower end of the screw. The support plate is slidably connected to the outer wall of the side mold.

[0013] Optionally, the pressure-applying roughening mechanism includes a sealing cover with a lower opening, which can abut against and seal against the base plate and completely cover the side mold. A pressure device is installed on the top of the sealing cover. A lead screw drive shaft is rotatably installed on each of the two sides inside the sealing cover. A movable support platform is threadedly connected to the two lead screw drive shafts. The two lead screw drive shafts are connected by a first transmission assembly. A first motor that is transmitted and connected to one of the lead screw drive shafts is fixed on the outer wall of the sealing cover. Multiple roughening plates are longitudinally slidably arranged on the movable support platform. A U-shaped rod is laterally slidably arranged on the upper end of the roughening plate. A lifting positioning plate is fixed across the upper end of the two branches of the U-shaped rod. A roughening adjustment telescopic cylinder for driving the lifting positioning plate to rise and fall is fixed on the top of the sealing cover.

[0014] Optionally, the lower end of the textured plate is integrated with a replaceable textured toothed plate assembly; the sealing surface of the sealing cover is embedded with a high-temperature resistant silicone sealing ring.

[0015] The composite board processing equipment provided by this invention has the following beneficial effects: The adjustable mold mechanism is driven by a vibration excitation mechanism to slowly rise and then fall rapidly under its own weight, achieving efficient compaction of concrete, effectively removing air bubbles, increasing density, and ensuring that the concrete fully fills the mold, significantly enhancing the strength, durability, and appearance quality of the component. At the same time, the pressure roughening mechanism can controllably roughen the concrete surface under sealed pressure to form a rough surface that meets the specifications, greatly improving the shear strength and bond strength between the precast composite slab and the post-cast concrete layer, thereby ensuring the integrity, structural safety, and long-term service performance of the prefabricated floor slab.

[0016] In summary, this invention significantly improves the density, surface roughness, and bonding performance with post-cast layers of composite slab concrete through the synergistic effect of gravity-impact vibration compaction and controlled roughening under sealed pressure, thereby ensuring the strength, durability, and overall structural reliability of the components.

Therefore, they should not be construed as limitations on this invention.

[0023] The following is a detailed description of a composite board processing device according to an embodiment of the present invention, with reference to the accompanying drawings.

[0024] like Figure 1-5 As shown, a composite board processing device according to an embodiment of the present invention includes a device base 1 and a device frame 2 fixedly mounted on it, and further includes: An adjustable mold mechanism 5 is provided with a guide post 7 slidingly on its outer side, and the lower end of the guide post 7 is fixed on the equipment base 1. Vibration excitation mechanism 6 is used to drive the adjustable mold mechanism 5 to rise slowly, and then the adjustable mold mechanism 5 falls quickly by its own gravity, thereby making the concrete poured inside the adjustable mold mechanism 5 dense. The vibration excitation mechanism 6 is provided on each side of the adjustable mold mechanism 5. Each vibration excitation mechanism 6 includes two support frames 62, the lower end of which is fixed to the equipment base 1. A support cylinder 67 is fixed on each support frame 62, and a rotating shaft 68 is rotatably mounted on the inner side of the support cylinder 67. A rotating plate 66 is rotatably connected to the support cylinder 67. The other end of the rotating plate 66 is hinged to a transmission plate 612 via a first connecting shaft 611, and the other end of the transmission plate 612 is connected to the adjustable mold mechanism 5 via a second connecting shaft 613. The two second connecting shafts 613 corresponding to the vibration excitation mechanism 6 in the same group are respectively located at the two outer ends of the adjustable mold mechanism 5. The two rotating shafts 68 corresponding to the vibration excitation mechanism 6 in the same group are connected by a second transmission assembly. A second motor 64 for driving the rotating shaft 68 to rotate is also fixed on one of the support frames 62 in the same group of vibration excitation mechanisms 6. A linkage column 610 is also fixed on the rotating plate 66, and a lever 69 that can move the linkage column 610 is fixed on the rotating shaft 68. Through the specific structural design of the vibration excitation mechanism 6, a second motor 64, in conjunction with a second transmission assembly, can drive two rotating shafts 68 on one side of the adjustable mold mechanism 5. The lever 69 rotates with the rotating shafts 68, which can move the linkage column 610, causing the rotating plate 66 to be slowly pulled upward with the help of the transmission plate 612. Then the linkage column 610 and the lever 69 separate, and the adjustable mold mechanism 5 falls rapidly under its own weight, making the concrete compact, venting, and fully filling the mold, thereby ensuring the strength, durability, appearance quality, and reliable bonding with the post-cast layer of the component.

[0025] The pressure roughening mechanism 4 is also installed on the equipment frame 2 via a sealed telescopic cylinder 3. The pressure roughening mechanism 4 is used to seal and pressurize the adjustable mold mechanism 5 and to control the roughening operation of the concrete poured in the adjustable mold mechanism 5, that is, to form a rough surface that meets the specifications on the surface of the molded composite slab, so as to ensure that it has sufficient shear strength and bond strength with the post-poured concrete layer, thereby ensuring the overall structural performance, safety and durability of the prefabricated floor slab.

[0026] In application, the adjustable mold mechanism 5 is driven by the vibration excitation mechanism 6 to slowly rise and then fall rapidly under its own weight, achieving efficient compaction of the concrete, effectively removing air bubbles, increasing density, and allowing the concrete to fully fill the mold, significantly enhancing the strength, durability, and appearance quality of the component. At the same time, the pressure roughening mechanism 4 performs controllable roughening of the concrete surface under sealed pressure, forming a rough surface that meets the specifications, greatly improving the shear strength and bond strength between the precast composite slab and the post-cast concrete layer, thereby ensuring the integrity, structural safety, and long-term service performance of the prefabricated floor slab.

[0027] like Figure 3-4As shown, in one embodiment, the adjustable mold mechanism 5 includes a base plate 51, and one guide post 7 is arranged at each of the four corners of the base plate 51 to improve the stability of the base plate 51 during lifting. A side mold 55 is provided on the upper side of the base plate 51, and the side mold 55 has a rebar positioning groove 56 for positioning rebars / rebar mesh. The side mold 55 can be manufactured using conventional processes and can be arranged as a detachable structure or an integral structure, which will not be elaborated further. An outer frame 52 is slidably fitted onto the outer side of the side mold 55 (the side mold 55 is located inside the outer frame 52, and the outer wall of the side mold 55 slides in conjunction with the inner wall of the outer frame 52). The lower side of the outer frame 52 is fixed to the base plate 51. A vibration telescopic cylinder 54 is provided, and the telescopic spindle end of the vibration telescopic cylinder 54 is fixedly connected to the outer frame 52. The outer frame 52 can be driven to rise and fall by adjusting the vibration telescopic cylinder 54. The outer side of the side mold 55 is also provided with a steel bar support column 53 for auxiliary support of steel bars / steel mesh. End blocks 57 are rotatably installed at both ends of the steel bar support column 53. The end blocks 57 are fixed on the outer frame 52. A first knob 58 is also fixed at the end of the steel bar support column 53. The end blocks 57 can stably support the steel bar support column 53. The first knob 58 can be operated to rotate the steel bar support column 53, thereby moving the steel bars / steel mesh to the designated position and improving the forming accuracy. Furthermore, by adjusting the height of the outer frame 52 through the vibration telescopic cylinder 54, the support height of the steel bar support column 53 for the steel bar / steel mesh can be adjusted, allowing for height adjustment of the steel bar / steel mesh arrangement, which is flexible in application. After the concrete is poured, in addition to using the vibration excitation mechanism 6 to vibrate the adjustable mold mechanism 5, the vibration telescopic cylinder 54 can also be controlled to reciprocate and extend within a small range, thereby micro-vibrating the steel bar / steel mesh, making the concrete adhere tightly to the steel bar / steel mesh, and venting air, further improving the component's forming strength, durability, appearance quality, and reliable bonding with the post-cast layer.

[0028] In one optional embodiment, a plurality of auxiliary demolding components are also fixed to the outer side of the side mold 55. The auxiliary demolding components include a support plate 59, a fixed support member 510, a screw 511, and a second knob 512. The fixed support member 510 is fixed to the outer side of the side mold 55. The screw 511 is threadedly connected to the fixed support member 510. The upper end of the screw 511 is fixed with the second knob 512. The lower end of the screw 511 is rotatably mounted with the support plate 59. The support plate 59 is also slidably connected to the outer wall of the side mold 55. During demolding, the second knob 512 can be operated to rotate the screw 511. Because the support plate 59 is slidably connected to the outer wall of the side mold 55, the support plate 59 will not twist and will move up and down. Then, by adjusting the vibration telescopic cylinder 54, the outer frame 52 is controlled to rise and fall and abut against the support plate 59, so that the side mold 55 can be separated from the bottom support plate 51. This facilitates the separation of the precast bottom layer (precast slab) inside the side mold 55 along with the side mold 55 and the bottom support plate 51, thus improving the overall demolding efficiency. It should be noted that in the normal state, the support plate 59 abuts against the fixed support member 510, so that the outer frame 52 has sufficient room for movement.

[0029] Preferably, the end of the steel bar support column 53 is integrated with a scale ring and a fine-tuning positioning pin. The scale ring is linked to the rotation angle of the first knob 58 to achieve precise adjustment of the position of the steel bar / steel mesh. In conjunction with the positioning reference line on the bottom support plate 51, the accuracy of the steel bar arrangement is improved.

[0030] Preferably, the reciprocating frequency and amplitude of the adjustable vibration telescopic cylinder 54 are intelligently matched and controlled. Its vibration frequency is preferably 40-80Hz and amplitude is 0.3-1.5mm. The PLC system automatically triggers small-range reciprocating expansion and contraction according to the initial setting time of the concrete (5-15 minutes after pouring), forming periodic micro-vibration, which effectively promotes the dense filling of the interface between concrete and steel reinforcement, while avoiding steel reinforcement displacement caused by excessive disturbance, thereby improving the density and increasing the shear strength of the component. The outer surface of the support plate 59 of the auxiliary demolding component is covered with a polymer anti-stick coating (such as polytetrafluoroethylene coating), and the sliding mating surface between the support plate 59 and the outer wall of the side mold 55 is provided with guide grooves and elastic buffer pads. During demolding, the lifting stroke of the support plate 59 and the contraction action of the adjustable vibration telescopic cylinder 54 are synchronously linked to form a three-stage progressive demolding mechanism of "micro-lifting-micro-vibration-separation", which significantly reduces the adsorption force between the side mold 55 and the precast slab, improves the demolding efficiency, and avoids corner damage caused by hard separation.

[0031] like Figure 4-5 As shown, in one embodiment, the second transmission assembly includes a second transmission member 61 and a second transmission wheel 65. The second transmission wheel 65 is fixed on the rotating shaft 68. The two second transmission wheels 65 are connected by the second transmission member 61. The second transmission member 61 can be a belt or a chain, and the second transmission wheel 65 can be a pulley or a sprocket.

[0032] The second motor 64 is fixedly connected to the support frame 62 via the second motor frame 63, so that the second motor 64 and the rotating shaft 68 are coaxial and can stably drive the rotating shaft 68 to rotate.

[0033] In one optional embodiment, the first connecting shaft 611 and the second connecting shaft 613 can be connected in a conventional way, such as the rotating plate 66 and the transmission plate 612 being rotatably connected to the first connecting shaft 611, the transmission plate 612 being rotatably connected to the second connecting shaft 613, and the second connecting shaft 613 being fixed to the outside of the base plate 51, which can meet the transmission requirements.

[0034] The length of the rotating plate 66 between the linkage column 610 and the first connecting shaft 611 can be adjusted, and / or the length of the transmission plate 612 can be adjusted, which can adjust the lifting distance of the adjustable mold mechanism 5 and the initial and falling positions of the adjustable mold mechanism 5, making it flexible, reliable and meeting the usage requirements.

[0035] Preferably, in the embodiment of the second transmission component, in order to deepen the technical disclosure and enhance the inventiveness, the following is added: the rim of the second transmission wheel 65 is provided with a precision toothed groove, which forms a high-precision meshing transmission with the toothed structure of the second transmission component 61 (belt or chain). The meshing gap is controlled within the range of 0.05-0.1mm, eliminating the slippage phenomenon of traditional belt transmission and ensuring that the rotational speed fluctuation rate of the rotating shaft 68 is ≤1.5%.

[0036] Preferably, the length adjustment mechanism of the rotating plate 66 adopts a double-thread synchronous adjustment structure, with adjusting screws at both ends that are threadedly connected to the first connecting shaft 611. The outer end of the adjusting screw is integrated with a scale and a locking nut. By rotating the adjusting screw, the length of the rotating plate 66 can be continuously adjusted steplessly. At the same time, the length adjustment of the transmission plate 612 adopts a modular quick-change design. The main body of the transmission plate 612 is a detachable multi-segment structure, and each segment is connected by magnetic snap-fit. The adjustment time for a single adjustment is shortened to within 5 seconds.

[0037] Preferably, in terms of vibration parameter optimization, the PLC control system automatically calculates and drives the adjustment mechanism based on the composite slab thickness parameters (e.g., 60-120mm), so that the amplitude (0.5-2.5mm) and frequency (30-100Hz) of the vibration excitation mechanism 6 are dynamically matched. When the thickness of the composite slab increases, the length of the rotating plate 66 automatically extends to increase the amplitude, ensuring that the uniformity of concrete density is improved. At the same time, the high-precision transmission of the second transmission component eliminates energy loss during vibration, thereby reducing equipment energy consumption.

[0038] In application, the coordinated design of the lever 69 and the linkage column 610 ensures that the adjustable mold mechanism 5 completes one "lift-release" cycle for each rotation of the rotating shaft 68. The vibration frequency can be controlled by adjusting the speed of the second motor 64, with a preferred range of 15-60 times / minute. The lifting height (i.e., amplitude) of the adjustable mold mechanism 5 can be changed by adjusting the length of the rotating plate 66 and / or the transmission plate 612, with a preferred range of 5-30mm. This gravity-impact vibration has high energy transfer efficiency, effectively overcoming internal friction and bonding forces in concrete, achieving deep compaction.

[0039] like Figure 1-2 As shown in Figures 6-8, in one embodiment, the number of the sealing telescopic cylinders 3 can be arranged as needed to stably drive the pressure-grinding mechanism 4 to rise and fall.

[0040] The pressure-applying roughening mechanism 4 includes a sealing cover 41 with a lower opening. The sealing cover 41 can abut against and seal the bottom support plate 51 and completely cover the side mold 55. A pressure device 42 capable of pressurizing its inner cavity is installed and fixed on the top of the sealing cover 41. A lead screw drive shaft 48 is rotatably installed on each of the two inner sides of the sealing cover 41. A movable support platform 410 is threadedly connected to the two lead screw drive shafts 48. The two lead screw drive shafts 48 are connected by a first transmission assembly. A first motor 45, which is transmitted and connected to one of the lead screw drive shafts 48, is also fixed on the outer wall of the sealing cover 41. Multiple roughening plates 49 are longitudinally slidably arranged on the movable support platform 410. A U-shaped rod 411 is laterally slidably arranged on the upper end of the roughening plate 49. A lifting positioning plate 412 is fixed across the upper end of the two branches of the U-shaped rod 411. A roughening adjustment telescopic cylinder 43 for driving the lifting positioning plate 412 to rise and fall is fixed on the top of the sealing cover 41. After the concrete is poured, the vibration excitation mechanism 6 can control the extension of the sealing telescopic cylinder 3 as needed to make the sealing cover 41 abut against the bottom support plate 51 before and after vibration compaction. Then, the pressurizing device 42 is activated to pressurize the inner cavity of the sealing cover 41, which can compact the concrete in the side mold 55. Then, according to the needs of concrete roughening, the height position of the roughening plate 49 can be adjusted by the roughening adjustment telescopic cylinder 43. Then, the first motor 45 can be started and driven by the first transmission component to move the moving support platform 410. The roughening plate 49 moves with the moving support platform 410. The U-shaped rod 411 can adapt to the lateral movement of the roughening plate 49, so that the roughening plate 49 can roughen the concrete as needed. It is flexible and reliable. That is, the lateral movement of multiple roughening plates 49 is synchronized, and the longitudinal movement can be controlled and adjusted individually without interference.

[0041] In one optional embodiment, the lower structure of the roughened plate 49 is not limited and can be arranged as needed; when the two lead screw drive shafts 48 rotate, the movable support platform 410 can move laterally in a consistent manner.

[0042] The first motor 45 is fixedly connected to the outer wall of the sealing cover 41 via the first motor frame 46 to ensure the reliability of the first motor 45; the first transmission assembly includes a first transmission wheel 44 and a first transmission component 47. The first transmission wheel 44 is fixed on the lead screw drive shaft 48, and the two first transmission wheels 44 are connected by the first transmission component 47; similarly, the first transmission component 47 can be a belt or a chain, and the first transmission wheel 44 can be selected as a pulley or a sprocket.

[0043] Preferably, the lower end of the texturing plate 49 of the pressure texturing mechanism 4 is integrated with a replaceable texturing tooth assembly, with a tooth height of 0.5-3.0mm and a tooth pitch of 5-10mm, which is precisely matched with the particle size of concrete aggregate to ensure uniform and controllable texturing depth; the texturing adjustment telescopic cylinder 43 is driven by a servo motor, with an adjustment accuracy of ±0.05mm and a texturing operation time of ≤10 seconds, which significantly improves efficiency.

[0044] Preferably, the pressurizing device 42 is a pneumatic or hydraulic system that applies moderate pressure to the surface of the concrete before its initial setting. The pressure range of the pressurizing device 42 is 0.2-0.5 MPa, and the PLC system intelligently matches the thickness of the composite slab (60-120 mm). When the thickness is ≤80 mm, the pressure is automatically increased to 0.3 MPa, and when the thickness is >80 mm, the pressure is increased to 0.4 MPa to avoid overpressure that could cause the concrete to crack. This pressure can further remove surface laitance and micro-air bubbles, increasing the surface density. On the other hand, it provides a stable pressure working surface for subsequent texturing operations, so that the concrete is in a micro-plastic state when the texturing teeth cut in, making it easy to form clear and uniform textures without collapsing.

[0045] Preferably, the sealing surface of the sealing cover 41 is embedded with a high-temperature resistant silicone sealing ring, with a sealing pressure ≥0.1MPa and zero leakage during the pressurization process; the surface of the roughened plate 49 is covered with a polytetrafluoroethylene anti-stick coating, so that there is no residue after the concrete is roughened, and the roughness Ra value of the roughened surface is stably controlled at 4-6μm, which meets the specifications. The shear strength of the component and the post-cast layer is improved, the roughening efficiency is increased, and the problems of uneven roughening depth, low efficiency and concrete adhesion in the prior art are solved.

[0046] The above embodiments of the present invention provide a composite slab processing equipment. A vibration excitation mechanism 6 drives an adjustable mold mechanism 5 to slowly rise and then rapidly fall under its own weight, ensuring the concrete is fully compacted, effectively vented, and completely fills the mold, significantly improving the strength, durability, and appearance quality of the component. A pressure roughening mechanism 4 controllably roughens the concrete surface, forming a compliant rough surface on the upper surface of the composite slab, ensuring sufficient shear strength and bond strength between it and the subsequent concrete layer, thereby guaranteeing the overall structural performance, safety, and reliability of the prefabricated floor slab. Simultaneously, by adjusting the height of the reinforcing bars and using small-range shaking assistance, the tight bonding between the concrete and reinforcing bars is further promoted, improving molding accuracy and structural synergy. During the demolding stage, efficient separation of the side mold 55 and the bottom support plate 51 is achieved, improving production efficiency and operational convenience.

[0047] The control, model, and circuit connection of each component are not specifically limited, and can be flexibly configured in practical applications. All circuits, electronic components, and modules involved are existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this invention does not involve improvements to the software and methods.

[0048] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
