Conductive connection device for electrical engineering

Abstract

The present invention relates to the field of electrical connection technology, and more specifically to a conductive connection device for electrical engineering, comprising a main body and an eccentric flap. A guide channel is provided on the main body so that when a cable is inserted into the main body, the guide channel causes the multi-core conductors of the cable to bend in an arc shape. The eccentric flap is rotated to apply uniform pressure to the bent multi-core conductors, thereby preventing a certain core conductor from being subjected to excessive tension due to excessive initial tension when the cable is subjected to axial tension. As a result, the risk of the conductor falling off is greatly reduced, ensuring that the electrical connection system can operate reliably under various complex working conditions.

Description

Technical Field

[0001] The present invention relates to the technical field of electrical connection, and in particular to a conductive connection device for electrical engineering. Background Art

[0002] A strip-free connector is a convenient device that allows electrical connections without stripping the insulation of the wires. It is widely used in fields such as electricity, electronics, home improvement, and automotive circuits. When using a strip-free connector, first insert the multi-core or single-core cable into the corresponding wiring hole of the strip-free connector. Then, by pressing, rotating, or applying external force with the help of a tool, the sharp structure of the metal piercing piece allows the metal piercing piece to penetrate the insulation layer of the cable under pressure and make close contact with the internal conductor. At the same time, the clamping parts and elastic elements inside the strip-free connector can apply a certain clamping force to the cable after piercing the insulation layer of the cable, preventing the cable from loosening, ensuring the reliability of the connection, and achieving a fast, stable, and reliable electrical connection.

[0003] However, after inserting a multi-core conductor into a strip-free connector, the initial tension of each conductor varies during tightening, influenced by factors such as operating force, insertion angle, and the connector's internal spatial structure. When the cable is subjected to axial tension, the conductor with the highest initial tension remains taut, leaving a relatively small margin of grip between it and the strip-free connector. Consequently, it is the first to experience the additional tension. Once the added tension exceeds the gripping force limit of the conductor and the strip-free connector, the conductor will detach from the connector, causing the entire electrical connection system to fail, leading to circuit breakage, equipment downtime, and other malfunctions. Summary of the Invention

[0004] Based on this, it is necessary to provide a conductive connection device for electrical engineering to address the problem that the wires of the current stripping-free wire connector are easily detached from the stripping-free wire connector.

[0005] The above purpose is achieved through the following technical solutions:

[0006] A conductive connecting device for electrical engineering comprises a main body and an eccentric flip cover.

[0007] A guide channel and a conductive plate are provided inside the main body. When the wire enters the main body, the guide channel is used to guide the wire to move along a preset path. The conductive plate is attached to the main body and is provided with a plurality of punching thorns.

[0008] The eccentric flap is fixedly provided with a rotating shaft, and the eccentric flap is rotatably connected to the main body via the rotating shaft. The rotating shaft is located at a non-geometric center position of the eccentric flap, and the end of the eccentric flap away from the rotating shaft can fit the wire.

[0009] The eccentric flap has an open state and a closed state. When the eccentric flap is in the open state, the end of the eccentric flap away from the rotating shaft does not fit the wire, and the wire can slide relative to the main body. When the eccentric flap is in the closed state, the eccentric flap can squeeze the wire so that multiple punching thorns pierce the insulation layer of the wire to form multiple conductive contact points.

[0010] Furthermore, it also includes an adjustment structure, a slide groove is provided in the main body, and the rotating shaft can move relative to the main body in the slide groove along the horizontal plane where the axis of the rotating shaft is located.

[0011] When the eccentric flip cover is in the closed state, the side wall of the eccentric flip cover contacting the wire is set as a first slope, and the side wall of the main body contacting the wire through the conductive plate is set as a second slope, and the first slope and the second slope are parallel to each other.

[0012] The adjusting structure is movably arranged on the main body, and is used to drive the rotating shaft and the main body to move relative to each other.

[0013] Furthermore, the adjustment structure includes a plurality of adjusting screws and a movable plate, one end of the movable plate is connected to the main body through the plurality of adjusting screws, and the plurality of adjusting screws are rotated to adjust the distance between the movable plate and the main body, and the other end of the movable plate is fixed with two parallel oblique rods, and the two oblique rods abut against both sides of the rotating shaft, and the oblique rods are used to push the rotating shaft of the eccentric flip cover to slide relative to the main body.

[0014] Furthermore, it also includes an anti-loosening structure, which is sleeved on the main body. After the main body and the eccentric flip cover lock the wire, the anti-loosening structure prevents the eccentric flip cover from switching from the closed state to the open state.

[0015] Furthermore, the anti-loosening structure includes an external shell, which is sleeved on the outside of the main body and is used to limit the eccentric flip cover.

[0016] Furthermore, elastic binding members are provided on both sides of the main body, and the elastic binding members have a free state in which they form an angle with the main body and a fastened state in which they are closed and pressed against the wire.

[0017] Furthermore, the anti-loosening structure also includes a threaded cover, and the threaded cover is connected to one end of the external shell through a thread.

[0018] Furthermore, a multi-petal pressure block is provided inside one end of the external shell connected to the threaded cover, and an arc-shaped pressure plate that cooperates with the multi-petal pressure block is provided inside the threaded cover.

[0019] Furthermore, the guide channel guides the wire to perform an arc-shaped bend inside the main body.

[0020] Furthermore, the punching thorns are provided in two groups, wherein one group of the punching thorns is provided at the bending position of the wire, and the other group of the punching thorns is provided at the position where the wire is squeezed by the main body and the eccentric flap when the eccentric flap is in the closed state.

[0021] The beneficial effects of the present invention are:

[0022] The present invention provides a conductive connection device for electrical engineering, comprising a main body and an eccentric flap. By providing a guide channel in the main body, a conductor is bent into an arc during insertion into the main body. The bent conductor is then squeezed by the eccentric flap. The pressure of the eccentric flap secures the bent portion of the conductor, balancing the tension experienced by each conductor. This prevents a conductor from experiencing excessive tension due to excessive initial tension when the cable is subjected to axial tension. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The present invention provides a conductive connection device for electrical engineering, which is suitable for various electrical line connection scenarios, and is particularly suitable for complex electrical systems such as industrial automation and automotive circuits that require frequent wiring and high connection stability requirements. The cable 600 can be a single-core wire 610 or a multi-core wire 610. The embodiment of the present invention uses a multi-core wire 610 for description. Specifically, Figures 1 to 11 As shown, the conductive connection device for electrical engineering provided by the embodiment of the present invention includes: a main body 110 and a conductive plate 210.

[0045] The main body 110 serves as the foundation for mounting other components. It is equipped with multiple wire grooves (not labeled in the figure). These grooves are elongated and have retaining protrusions on both sides of the groove walls to stabilize the position of the wires 610 and prevent them from shifting during connection.

[0046] The conductive plate 210 is formed as a whole using a highly conductive metal material. The conductive plate 210 fits tightly against the inner wall of the main body 110. The conductive plate 210 is provided with a pin 220 and a punching spike 230. The pin 220 is mainly used to realize the conduction function of the electrical connection. When the two connecting devices are connected, there are a male connector and a female connector. The male connector is provided with a pin 220, and the female connector is provided with a conductive component connected to the pin 220. When the male connector and the female connector are docked, the pin 220 of the male end can fit tightly against the conductive component of the female end, ensuring that the current can pass smoothly and form a stable electrical path. The punching spike 230 is used to pierce the insulation layer of the wire 610. The punching spike 230 is usually in the shape of a sharp pyramid or sawtooth. By applying external force, the punching spike 230 can pierce the insulation layer outside the multi-core wire 610, so that the punching spike 230 is in direct contact with the internal conductor. At the same time, the tight engagement structure formed by the punching thorns 230 in contact with the conductor further enhances the firmness of the connection and the reliability of the electrical connection.

[0047] The multi-core conductor 610 is composed of multiple individual conductors 610 twisted together, each of which is covered with an insulation layer. When using the electrical engineering conductive connection device, the conductor 610 is placed in the conductor groove of the main body 110, and the punching barbs 230 contact and pierce the insulation layer of the conductor 610, tightly engaging the internal conductor of the conductor 610 to establish an electrical connection.

[0048] However, due to slight deviations in the insertion angle of the wires 610 when the cable 600 is inserted into the electrical connection device, as well as the limited internal space layout of the main body 110, the pressure on each wire 610 during the tightening process is unevenly distributed. This directly leads to differences in the initial tension of each wire 610, causing some wires 610 to be over-tightened while others are relatively loose. When the cable 600 is subjected to axial tension, the wire 610 with the higher initial tension and in a taut state will be the first to bear the load exceeding its load capacity when subjected to additional tension, and will be separated from the electrical connection device, compromising the integrity of the entire electrical connection system.

[0049] Based on this, the conductive connection device for electrical engineering provided by the embodiment of the present invention further includes an eccentric flip cover 310 .

[0050] Specifically, a guide channel is provided inside the main body 110. When the wire 610 enters the main body 110, the guide channel guides the wire 610 to perform an arc bend, such as Figure 7 and Figure 8 After the guide wire 610 of the guide channel is bent along the main body 110 , the bent wire 610 forms an acute angle with the unbent wire 610 .

[0051] The eccentric flap 310 is provided with a plurality of protrusions, which correspond to the limiting protrusions on both sides of the groove wall of the wire groove, and together constrain the position of the multi-core wire 610. The eccentric flap 310 is fixedly provided with a rotation axis 320, which is located at the bend of the wire 610. The eccentric flap 310 is rotatably connected to the main body 110 via the rotation axis 320. The rotation axis 320 is located at a non-geometric center position of the eccentric flap 310. The end of the eccentric flap 310 away from the rotation axis 320 can contact the wire 610. When the eccentric flap 310 and the main body 110 rotate relative to each other, the end of the eccentric flap 310 away from the rotation axis 320 moves more than the end closer to the rotation axis 320.

[0052] Among them, the eccentric flip cover 310 has an open state and a closed state. When the eccentric flip cover 310 is in the open state, the eccentric flip cover 310 and the main body 110 form an open channel, and the wire 610 passes into the main body 110 from the open channel; when the eccentric flip cover 310 is in the closed state, the eccentric flip cover 310 squeezes the wire 610 and causes multiple stamping thorns 230 to pierce the insulation layer of the wire 610.

[0053] When the eccentric flip cover 310 is in an open state, the multi-core wire 610 enters the main body 110 , and the guide channel guides the wire 610 to bend in an arc shape.

[0054] During the closing process of the eccentric flip cover 310 , the eccentric flip cover 310 rotates around the rotation axis 320 , generating a larger displacement at the end away from the rotation axis 320 , thereby applying an increasing pre-tightening force to the bent wire 610 .

[0055] When the eccentric flap 310 is closed, it applies a continuous and stable compressive force to the multi-core conductors 610. Simultaneously, the conductors 610 are bent within the main body 110, causing elastic deformation. This elastic deformation generates an elastic restoring force in the opposite direction of the conductors 610. This elastic restoring force, combined with the compressive force of the eccentric flap 310, creates a secure clamping force. When the cable 600 is subjected to axial tension, the clamping force created by the elastic restoring force and the compressive force of the eccentric flap 310 evenly distributes the axial tension to each conductor 610, thereby preventing a single conductor 610 from being subjected to excessive tension and significantly reducing the risk of the conductors 610 falling off.

[0056] Furthermore, existing stripping-free connectors are manufactured in a variety of sizes for cables 600 of varying diameters. While this can meet diverse usage requirements, it significantly increases the complexity of the production process. Therefore, the electrical engineering conductive connection device provided in an embodiment of the present invention further includes an adjustment structure 400 , which is movably mounted on the main body 110 and is used to drive the rotation shaft 320 to move relative to the main body 110 to accommodate wires 610 of varying diameters.

[0057] Specifically, a transverse sliding groove 113 is provided on the main body 110 , and both ends of the rotating shaft 320 are embedded in the sliding groove 113 . The rotating shaft 320 can drive the eccentric flip cover 310 and the main body 110 to move relative to each other in the transverse direction.

[0058] When the eccentric flip cover 310 is in the closed state, the side wall of the eccentric flip cover 310 that contacts the wire 610 is set to a first slope, and the side wall of the main body 110 that contacts the wire 610 through the conductive plate 210 is set to a second slope, and the first slope and the second slope are parallel to each other. Figure 7 and Figure 8 As shown, when the rotating shaft 320 causes the eccentric flip cover 310 to move toward the direction close to the ejector pin 220, the first inclined surface and the second inclined surface approach each other, so that the distance between the eccentric flip cover 310 and the main body 110 decreases; similarly, when the rotating shaft 320 causes the eccentric flip cover 310 to move toward the direction away from the ejector pin 220, the first inclined surface and the second inclined surface move away from each other, so that the distance between the eccentric flip cover 310 and the main body 110 increases.

[0059] The adjustment structure 400 includes multiple adjustment screws 410 and a movable plate 420. One end of the movable plate 420 is connected to the main body 110 through multiple adjustment screws 410. Rotating the multiple adjustment screws 410 can adjust the distance between the movable plate 420 and the main body 110. Two parallel inclined rods 430 are fixedly provided at the other end of the movable plate 420. The two inclined rods 430 abut against both sides of the rotating shaft 320. When the movable plate 420 moves up and down relative to the main body 110, the inclined rod 430 pushes the rotating shaft 320, so that the eccentric flip cover 310 and the main body 110 slide relative to each other in the horizontal direction.

[0060] When a smaller-diameter wire 610 needs to be accommodated, the adjustment screw 410 is rotated forward, causing the movable plate 420 to rise. The inclined rod 430 at the other end of the movable plate 420 pushes the rotating shaft 320 to slide toward the ejector pin 220. The passageway for the wire 610 between the eccentric flap 310 and the main body 110 is reduced, allowing the eccentric flap 310 and the main body 110 to apply a compressive force to the smaller-diameter wire 610. Conversely, when a larger-diameter wire 610 needs to be accommodated, the adjustment screw 410 is rotated backward, causing the movable plate 420 to fall. The inclined rod 430 on the movable plate 420 pushes the rotating shaft 320 to slide away from the ejector pin 220. The passageway for the wire 610 between the eccentric flap 310 and the main body 110 is increased, allowing the eccentric flap 310 and the main body 110 to apply a compressive force to the larger-diameter wire 610.

[0061] Therefore, when it is necessary to replace the wire 610 with a different caliber, the pressing force can be compensated by adjusting the structure 400, so that the same electrical engineering conductive connection device can be compatible with wires 610 of various calibers.

[0062] Furthermore, the conductive connection device for electrical engineering provided in an embodiment of the present invention also includes an anti-loosening structure 500, which is sleeved on the main body 110. After the main body 110 and the eccentric flip cover 310 lock the wire 610, the anti-loosening structure 500 prevents the eccentric flip cover 310 from switching from a closed state to an open state.

[0063] Specifically, elastic binding members 120 are fixedly provided on both sides of the main body 110. The elastic binding members 120 have a free state and a fastened state. When the elastic binding members 120 are in the free state, they form an angle with the main body 110; when the elastic binding members 120 are in the fastened state, the two elastic binding members 120 are forced to close and gather, tightly biting the outer surface of the cable 600.

[0064] The anti-loosening structure 500 includes an external housing 510 and a threaded cap 520. The external housing 510 is mounted on the exterior of the main body 110. When the eccentric flap 310 enters the locked state, the external housing 510 restrains the eccentric flap 310. Simultaneously, the radial pressure exerted by the inner wall of the external housing 510 forces the elastic binding member 120 to retract inward, transitioning the elastic binding member 120 from a free state to a tightened state. The threaded cap 520 is threadedly connected to one end of the external housing 510 and is used to lock the external housing 510 and the cable 600.

[0065] First, the external housing 510 and threaded cap 520 are pre-installed on the cable 600. After the eccentric flap 310 is rotated to the closed position and the punching spikes 230 pierce the insulation of the wire 610, the external housing 510 is pushed toward the main body 110. The external housing 510 engages the eccentric flap 310, preventing it from turning over. Simultaneously, the inner wall of the external housing 510 drives the elastic binding member 120 to clamp the cable 600. Finally, the threaded cap 520 is tightened, and its axial tension is transmitted to the external housing 510 through the threaded assembly, further compressing the elastic binding member 120 and squeezing the cable 600.

[0066] The external shell 510 provides the eccentric flip cover 310 with flipping resistance, the deformation of the elastic binding member 120 generates a continuous clamping force on the cable 600, and the spiral fastening of the threaded cover 520 further enhances the overall sealing, thereby improving the stability of the cable 600 connection.

[0067] Furthermore, in order to enable the external shell 510 and the threaded cover 520 to adapt to cables 600 of different calibers, a multi-petal pressure block is provided inside the end where the external shell 510 is connected to the threaded cover 520, and an arc-shaped pressure plate is provided inside the threaded cover 520 to cooperate with the multi-petal pressure block.

[0068] On the inner wall of one end of the external shell 510 close to the threaded cover 520, there are evenly distributed multiple radially movable pressure blocks. The pressure blocks are fan-shaped, with tiny gaps between adjacent pressure blocks, which can shrink toward the center when subjected to force. Inside the threaded cover 520, there is an arc-shaped pressure plate that cooperates with the pressure blocks. When the threaded cover 520 is screwed together with the external shell 510, as the threaded cover 520 is continuously tightened, the arc-shaped pressure plate gradually approaches the multiple-petal pressure blocks. Due to the curved surface structure of the arc-shaped pressure plate, when applying pressure to the multiple-petal pressure blocks, the arc-shaped pressure plate will convert the axial force into radial force, forcing the multiple-petal pressure blocks to shrink toward the center.

[0069] After the eccentric flap 310 has squeezed the wire 610 and the external housing 510 has limited the eccentric flap 310, the threaded cover 520 is tightened. As the threaded cover 520 rotates, the arc-shaped pressing plate gradually contacts the multi-petal pressing block, causing the multi-petal pressing block to squeeze the cable 600 from multiple directions.

[0070] When the diameter of the cable 600 is small, the multi-petal pressure block is retracted to a large extent and tightly wraps the cable 600; when the diameter of the cable 600 is large, the multi-petal pressure block is retracted to a small extent and can also fit tightly with the outer surface of the cable 600, thereby achieving stable locking of cables 600 of different diameters.

[0071] Furthermore, the plurality of punching thorns 230 are arranged into two groups, such as Figure 7 and Figure 8 As shown, one group of stamping spikes 230 is set at the bending position of the wire 610, and another group of stamping spikes 230 is set at the position where the wire 610 is squeezed by the main body 110 and the eccentric flip cover 310 when the eccentric flip cover 310 is in the closed state. The multiple stamping spikes 230 in each group are evenly distributed in a matrix form.

[0072] When the eccentric flap 310 rotates from an open position to a closed position via the rotating shaft 320, it applies pressure to the wire 610, causing stress concentration between the punched spikes 230 and the surface of the wire 610. When the pressure exceeds the puncture resistance of the insulation layer, the punched spikes 230 quickly pierce the insulation layer on the outside of the wire 610, making close contact with the inner conductor. The multiple conductive contact points formed by the multiple punched spikes 230 are electrically connected in parallel, reducing contact resistance and effectively preventing poor contact and unstable connections, ensuring stable operation of the electrical system.

[0073] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
