Description

Technical Field

[0001] The present invention relates to the technical field of line connectors, and in particular to a wiring device. Background Art

[0002] The use of electrical equipment often requires the connection of wires. Most of the quick wiring devices for safe voltages on the market are inconvenient to use and have no waterproof function, and are not suitable for harsh outdoor conditions such as wind and rain. The common quick wiring devices currently used are usually to press the tail end of the power cord into a plastic part using a special tool (or fix the power cord in the plastic part by injection molding). There is a copper sheet with a spike at one end in the plastic part that is connected to the wire, and the spike end is exposed outside the plastic part. During use, the exposed copper sheet spikes pierce the insulation layer of the power cord and connect to the internal wires through threads or buckles, thereby achieving the connection between the main line and the branch line. From the factory side, this method requires the factory to first connect the power cord to the plastic part by injection molding, and then assemble the product, which will bring inconvenience to assembly and cumbersome production steps. Therefore, many manufacturers do not install fixed wiring devices on the product power cord, but provide wiring devices separately. This requires leading out a power cord of more than ten centimeters on the wiring device for interconnection with the product's lead-out wires. This is not only inconvenient for customers to use, but also increases the instability of the circuit system. From the client's perspective, this product has no protective properties. Over time, the copper sheet will oxidize and corrode, and there will be risks of local heating or even leakage when encountering rain or contact with other impurities. Summary of the invention

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] like Figure 1-Figure 8 As shown, an embodiment of the present invention provides a wiring device, including a first cover body 10, a second cover body 20, a conductive metal sheet 30, a spinning plate 40 and a sealing device 50. The second cover body 20 is detachably connected to the first cover body 10. In the embodiment of the present invention, the second cover body 20 is screwed to the first cover body 10 by threads. Of course, the second cover body 20 can also be connected to the first cover body 10 by snap-on lap joints or the like. The first cover body 10 is used to accommodate wires. The bottom surface of the first cover body 10 is circular, and the upper part of the outer surface is a first thread segment 13. The first thread segment 13 is used to be threadedly connected to the second cover body 20. The lower part of the outer surface has a plurality of smoothly connected edges, which is convenient for the operator to hold the hand non-slip. A plurality of wire holes 11 are arranged on the side of the first cover body 10. In the embodiment of the present invention, the wiring device is used to realize the connection between a main line wire 60 and a branch line wire 70. Therefore, three wire holes 11 are arranged on the side of the first cover body 10, two of which are used to pass through a main line wire 60, and the other wire hole 11 is used to pass through the branch line wire 70. In other embodiments, according to the actual number of connecting wires, the side of the first cover 10 may be provided with other numbers of wire holes 11, which is not limited to this embodiment. The conductive metal sheet 30 is an L-shaped sheet, and the two ends of the L-shape have upward spike ends, such as Figure 4 As shown. The conductive metal sheet 30 is fixed on the inner side of the first cover body 10, and is arranged on the upper part of the conductive metal sheet 30 when the wires are connected. The spiked end of the conductive metal sheet 30 is used to pierce the outer insulation layer of the wire and contact the inner core of the wire, thereby realizing the circuit connection between the wires. The number of the conductive metal sheets 30 is determined according to the number of cores of the wire. In the embodiment of the present invention, the main wire 60 and the branch wire 70 are two-core wires, so two L-shaped conductive metal sheets 30 are provided. The two conductive metal sheets 30 are placed side by side and spaced apart. When the spiked end of the same conductive metal sheet 30 pierces the main wire 60 and the branch wire 70 respectively, the circuit connection of one inner core of the main wire 60 and the branch wire 70 is realized, and the two conductive metal sheets 30 realize the complete connection of the two-core wires. Moreover, the design of the spiked end makes the insulating layer pierced only at the conductive part, and the other parts of the wire are intact, without the risk of leakage, and the safety is extremely high.

[0042] Preferably, if Figure 2As shown, the second cover body 20 is similar in appearance to the first cover body 10, with a circular bottom surface and a second threaded section 22 inside the side surface. The second threaded section 22 is used to be threadedly connected with the first threaded section 13 of the first cover body 10; the outside of the side surface has multiple smoothly connected edges, which is convenient for the operator to hold and rotate the cover body without slipping. Anti-UV and flame retardants are added to the second cover body 20 and the first cover body 10 to improve weather resistance and flame retardancy, and increase the safety performance of the equipment. The spinning plate 40 is located between the second cover body 20 and the first cover body 10, and a protrusion 41 is provided on its lower side at a position corresponding to the conductive metal sheet 30. When performing wiring operations, the operator rotates the second cover body 20, thereby squeezing the spinning plate 40 downward, and the protrusion 41 on the spinning plate 40 presses the wire located on the conductive metal sheet 30 downward, forcing the wire insulation sheath to be quickly pierced by the spiked end of the conductive metal sheet 30. On the one hand, the setting of the protrusion 41 can apply force accurately so that the conductive metal sheet 30 can quickly pierce the insulating sheath of the wire. On the other hand, the protrusion 41 can squeeze and fix the wire, and cooperate with the pointed end of the conductive metal sheet 30 up and down to prevent the wire from detaching, thereby ensuring the reliability of connection and circuit conduction.

[0043] The sealing device 50 is used to seal the gap between the spinning plate 40 and the first cover body 10. Further, the sealing device 50 includes an upper sealing ring 51 and a lower sealing ring 52. The lower sealing ring 52 is fixed to the inner side of the first cover body 10, and the upper sealing ring 51 is fixed to the inner side of the spinning plate 40. In order to achieve a better fit with the inner side of the cover body, the upper sealing ring 51 and the lower sealing ring 52 are both circular in shape, and the inner side of the cover body is sealed while avoiding the area where the wire is located.

[0044] Furthermore, the side of the upper sealing ring 51 has a plurality of first sealing blocks 511, and the side of the lower sealing ring 52 has a plurality of second sealing blocks 521. The first sealing blocks 511 and the second sealing blocks 521 correspond to the wire holes 11 of the first cover 10 one by one. Therefore, in the embodiment of the present invention, the side of the upper sealing ring 51 has three first sealing blocks 511, and the side of the lower sealing ring 52 has three second sealing blocks 521. The first sealing blocks 511 and the second sealing blocks 521 are both located in the wire holes 11, and cooperate with each other to wrap the wires, so as to prevent external dust and water vapor from entering the interior of the wiring device through the wire holes 11, and to prevent the conductive metal sheet 30 from rusting, and are suitable for a variety of harsh working environments such as humidity, dust, and outdoor rain and snow weather. The overall design of the sealing device 50 can reliably seal the internal wiring area of ​​the wiring device, thereby achieving a dustproof and waterproof effect, effectively avoiding the risk of leakage caused by oxidation of the conductive metal sheet 30, and making the entire electrical system safer and more stable.

[0045] Furthermore, if Figure 3As shown, the side of the spinning plate 40 has a plurality of first stop blocks 42, and the first stop blocks 42 correspond to the wire holes 11 one by one, and are used to limit the rotation of the spinning plate 40. In the embodiment of the present invention, three first stop blocks 42 are provided on the side of the spinning plate 40. The first stop blocks 42 enable the spinning plate 40 to be placed accurately, and can prevent the spinning plate 40 from rotating when the second cover 20 is screwed on, thereby ensuring the squeezing effect of the spinning plate 40 on the wire.

[0046] Furthermore, the sealing device 50 is made of rubber, which has good elasticity and recovery ability, strong anti-aging performance, can effectively compensate for the gap, and has good sealing performance.

[0047] Furthermore, if Figure 2 , Figure 3 As shown, the second cover 20 has a first annular boss 21 on the inner side, and the second cover 20 presses the spinning plate 40 through the first annular boss 21. The provision of the first annular boss 21 makes the spinning plate 40 more concentratedly stressed. When the wiring device is used, the operator only needs to gently rotate the second cover 20 to apply pressure to the spinning plate 40.

[0048] Furthermore, the first cover 10 has a plurality of wire grooves 12 on the inner side, and the outlets of the wire grooves 12 correspond to the wire holes 11. In the embodiment of the present invention, the first cover 10 has two wire grooves 12: a main wire groove and a branch wire groove, which are used to accommodate the main wire 60 and the branch wire 70 respectively. The arrangement of the wire grooves 12 prevents the wires from curling in the wiring device, thereby affecting the accuracy of the conductive metal sheet 30 piercing the insulation layer of the outer skin of the wire. The main wire groove connects two wire holes 11, and the branch wire groove connects one wire hole 11.

[0049] Furthermore, a second boss 43 is provided on the upper side of the spinning plate 40 , and the operator can easily take out the spinning plate 40 by holding the second boss 43 .

[0050] Furthermore, the conductive metal sheet 30 is located in the wire groove 12. To achieve a better fixing effect, the conductive metal sheet 30 can be injection molded into one piece with the first cover body 10. Preferably, the conductive metal sheet 30 is an L-shaped metal sheet, and the spike ends at both ends are exposed from the inner surface of the first cover body 10 and are vertically upward. Preferably, the conductive metal sheet 30 is made of a copper sheet, and the surface is treated with rust and oxidation prevention. The copper sheet has high conductivity and high strength. The surface treatment optimizes the conductivity, thereby increasing the service life of the product and the reliability of the circuit connection.

[0051] Furthermore, the sealing device 50 further comprises a first sealing sheet 53, a second sealing sheet 54 and a third sealing ring 55, which are respectively located in the two wire grooves 12, and the first sealing sheet 53 and the second sealing sheet 54 are used for sealing the conductive metal sheet 30 and for local reliable sealing at the place where the conductive metal sheet 30 pierces the wire, and the third sealing ring 55 is used for sealing the end of the branch wire 70. Preferably, the first sealing sheet 53 and the second sealing sheet 54 have through holes, and the spiked end of the conductive metal sheet 30 can pass through the through holes, exposing the upper surfaces of the first sealing sheet 53 and the second sealing sheet 54.

[0052] Furthermore, the end surface of the wire hole 11 of the first cover body 10 is provided with a plurality of first limiting grooves 14, and the spinning plate 40 is provided with a plurality of second limiting blocks 44; the second limiting blocks 44 are located in the first limiting grooves 14, and cooperate to indicate the screwing state of the second cover body 20. Figure 7 , Figure 8 As shown, if the second stopper 44 is higher than the upper surface of the first stopper groove 14, it means that the second cover 20 is not screwed into place; if the second stopper 44 is lower than the upper surface of the first stopper groove 14, it means that the second cover 20 is screwed into place, and the sealing device 50 is in an effective sealing state. The first stopper groove 14 and the second stopper 44 are provided to prevent the second cover 20 from being screwed insufficiently, resulting in the sealing device 50 being unable to achieve a good sealing effect, and to prevent the second cover 20 from being screwed too tightly, resulting in the conductive metal sheet 30 squeezing and damaging the wire.

[0053] In this embodiment, when the wiring device is used, the main line conductor 60 is first placed in the main line wiring groove, and the branch line conductor 70 is placed in the branch line wiring groove. Then, the spinning plate 40 with the upper sealing ring 51 is covered on top of the first cover body 10. Note that the limit block 42 of the spinning plate 40 is placed in the wire hole 11 of the first cover body 10. Finally, the second cover body 20 is covered and gently screwed. When the second cover body 20 is threadedly connected to the first cover body 10, the spinning plate 40 is squeezed by the second cover body 20, and the protrusion 41 under the spinning plate 40 presses the wire downward, causing the insulating layer of the wire sheath to be quickly pierced by the sharp end of the conductive metal sheet 30, thereby realizing the circuit connection between the main line conductor 60 and the branch line conductor 70. When the second cover body 20 is screwed, the spinning plate 40 is pressurized to gradually compress the sealing device 50, and the position of the second limit block 44 in the first limit groove 14 gradually decreases. When the second limit block 44 is lower than the upper surface of the first limit groove 14, the second cover body 20 is screwed into place, and the wire connection and effective sealing are completed.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
