Description

Technical Field

[0001] This utility model relates to the field of cable connection technology, and specifically to a wiring device. Background Technology

[0002] There are two methods for wiring electrical components. The traditional method involves stripping the insulation from both ends of the cables, winding them together, and then wrapping the connector with insulating tape. This method is not only unsightly but also cumbersome, time-consuming, and labor-intensive, especially when connecting two rigid cables or a rigid-to-flexible cable. The second method is to use connectors, which is currently the most common and convenient connection method in household appliances, such as for wiring light fixtures. The most commonly used connector is the push-button quick connector; the protruding cable end is inserted into the corresponding socket, and the spring contacts secure it to the pressure plate.

[0003] However, the existing press-type quick connectors also have the following drawbacks: for thinner, softer cables, the connection effect is not good, and it is only achieved by a fixed pressing point between the spring and the pressure plate, so the connection is not reliable and it is easy to loosen. Utility Model Content

[0004] The purpose of this utility model is to provide a wiring device to solve the technical problems of unreliable connection of flexible cables and easy loosening in the prior art.

[0005] To achieve the above objectives, the present invention provides a wiring device with the following technical solution: A wiring device includes an insulating housing, the insulating housing having at least one mounting cavity, a conductor metal sheet being disposed in the mounting cavity, the conductor metal sheet having upwardly folded spring pieces at both ends, the insulating housing having insertion ports corresponding to each spring piece for the stripped end of the cable to extend into, each spring piece having a winding post or insertion hole, and each spring piece having two or more upwardly protruding bent portions spaced apart along the cable extension direction, and an insulating pressure plate for fixing the cable being disposed at each insertion port on the insulating housing.

[0006] The lower surface of the insulating pressure plate is provided with a protrusion for engaging with the bending section to fix the cable.

[0007] The protrusion includes a ridge that corresponds one-to-one with the bend.

[0008] One end of each pressure plate is rotatably connected to an insulating housing, and the other end is provided with a locking post. The housing is provided with a locking hole for inserting the locking post, and the locking post is provided with a locking protrusion that engages with the locking hole.

[0009] The housing is provided with a groove, the locking hole is located on the bottom of the groove, the pressure plate is provided with a protrusion that matches the groove, and the locking post is located on the protrusion.

[0010] The housing is provided with a mounting hole, the upper wall of the mounting hole is open and has a narrowing structure, and the pressure plate is provided with a rotating shaft that rotates with the mounting hole and is limited by the narrowing structure.

[0011] The bottom wall of the mounting cavity is provided with a limiting protrusion, and the conductor metal sheet is provided with a bending groove that matches the limiting protrusion for limiting installation. The limiting protrusion and the conductor metal sheet are fixedly connected by screws.

[0012] The top of the housing has a through hole for the screw to pass through.

[0013] The beneficial effects of this invention are as follows: After the insulation is stripped from the end of the flexible cable, it is called the stripped end. This stripped end extends from the insertion port into the spring inside the insulating shell. It is then wound around the winding post or passes through the insertion hole and secured by the insulating pressure plate. Because the spring has multiple upward-protruding bends, which, in conjunction with the insulating pressure plate, form multiple cable fixing points, and combined with the winding post or insertion hole, the cable's stability is greatly increased, ensuring it is not easily loosened. Furthermore, the wiring device of this invention does not affect the connection of rigid cables and can be used for both rigid and flexible cables, making it widely applicable and convenient to use.

[0020] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0021] It should be noted that, unless otherwise defined, the technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The use of "belonging" in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this invention.

[0022] One embodiment of the wiring device of this utility model is as follows: Figures 1-3 As shown, the device includes an insulating housing 1, within which a mounting cavity 2 is provided. A conductor metal sheet 3 is disposed within the mounting cavity 2, and both ends of the conductor metal sheet have upwardly folded elastic tabs 4. A limiting protrusion 18 is provided on the bottom wall of the mounting cavity, and a bending groove 19 is provided on the conductor metal sheet to limit and mate with the limiting protrusion. Figure 3 As shown. In this embodiment, the longitudinal section of the limiting protrusion is a trapezoidal structure, and the bending groove is a matching trapezoidal groove structure. The limiting protrusion and the conductor metal sheet are fixedly connected by screws 15. The top of the housing is provided with a through hole 16 for the screw to pass through. The advantage of this design is that the conductor metal sheet is horizontally inserted into the mounting cavity, and the screw is directly passed through the top of the housing for fixation.

[0023] The insulating housing 1 has an inlet corresponding to each spring for the stripped end of the cable to enter. Each spring is provided with a winding post 6, and each spring 4 has two or more upwardly protruding bends 5 spaced apart along the cable insertion direction. In this embodiment, there are three bends. An insulating pressure plate 7 for fixing the cable is provided at each inlet on the insulating housing. Specifically, the lower surface of the insulating pressure plate has a protrusion for pressing against the bends to fix the cable. In this embodiment, the protrusion includes a ridge 8 corresponding to each bend. During the connection between the insulating pressure plate and the housing, the ridges and bends work together to form multiple compression and limiting fixation of the cable.

[0024] Each insulating pressure plate 8 has one end rotatably connected to an insulating housing, and the other end is provided with a locking post 10. The housing has locking holes 13 for inserting the locking posts, and the locking posts have locking protrusions 11 that engage with the locking holes. Specifically, the housing has mounting holes with an open upper wall and a constricted structure. The pressure plate has a rotating shaft 9 that rotatably engages with the mounting holes and is limited by the constricted structure. In this embodiment, for the sake of a flat overall shape, the housing has a groove 12, the locking holes 13 are located at the bottom of the groove, the pressure plate has a protrusion 14 that matches the groove, and the locking posts 10 are located on the protrusion 14. To facilitate the smooth insertion of thicker cables into the mounting cavity, a notch 17 is provided on the mounting plate.

[0025] In this embodiment, one wiring device corresponds to the wiring of one cable. Two wiring devices are needed for two cables, and similarly, three wiring devices are needed for three cables. In use, for thinner, flexible cables, the stripped end is inserted into the mounting cavity through the inlet and positioned above the corresponding spring clip. The stripped end is then wound around the winding post and secured with an insulating pressure plate. For thicker, flexible cables (cables with multiple strands of fine copper wire), the winding post is not required; the insulating pressure plate can be used directly for fixation. Similarly, for rigid cables, the winding post is not required; the insulating pressure plate can be used directly for fixation. This wiring device is well-suited for wiring both flexible and rigid cables.

[0026] In the foregoing description of this specification, unless otherwise expressly specified and limited, the terms "fixed," "installed," "connected," or "joined" should be interpreted broadly. For example, the term "joined" can refer to a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can refer to the internal communication of two components or the interaction between two components. Therefore, unless otherwise expressly limited in this specification, those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Based on the above description in this specification, those skilled in the art will also understand that terms used, such as "upper," "lower," "front," "rear," "left," "right," "length," "width," "thickness," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," "circumferential," "center," "longitudinal," "transverse," "clockwise," or "counterclockwise," are terms indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0028] Furthermore, the terms "first" or "second," etc., used in this specification to refer to numbers or ordinal numbers are for descriptive purposes only and should not be construed as indicating, explicitly or implicitly, relative importance or specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this specification, "a plurality of" means at least two, such as two, three, or more, unless otherwise explicitly specified.

[0029] A second embodiment of the wiring device of this utility model, such as Figure 4 As shown, the only difference from Embodiment 1 is the structure of the protrusion. In this embodiment, the protrusion is an integral protruding plane 8, and the cable is squeezed and fixed by the protruding plane and the bending part on the spring piece.

[0030] A third embodiment of the wiring device of this utility model, such as Figure 5 As shown, the only difference from Embodiment 1 is that the winding post is replaced by the insertion hole 20. Thin, soft cables can be wound around the insertion hole (by passing through at least twice to achieve winding), while thick, soft cables and hard cables can simply have their ends inserted into the insertion hole without winding.

[0031] Embodiment four of the wiring device of this utility model, such as Figure 6 As shown, the only difference from Embodiment 1 is that the housing has two mounting cavities, which can be used to connect two cables.

[0032] In other embodiments of this utility model, the outer casing may also include three mounting cavities to realize the wiring of three cables; the number of bending parts can also be adjusted according to the actual situation, for example, two; the mounting hole can be a complete hole, and the shaft is rotated and installed in the mounting hole, but the installation is slightly more troublesome, requiring the outer casing to be bent for installation.
