Description

Technical Field

[0001] This utility model relates to the field of power conversion connector technology, specifically a novel plug with a conversion socket expansion function that can be connected to wires. Background Technology

[0002] Most existing adapter sockets on the market are simple socket expansion structures. They need to be plugged into existing wall sockets and can only increase the number of sockets in the same location. The power supply location is limited by the installation position of the original socket and cannot flexibly extend the power supply distance. When the electrical equipment is far from the socket and there are not enough sockets on site, it is usually necessary to use a pre-made power strip for expansion. The purchase cost is high, and the power strip cord length is fixed, so it cannot be flexibly adjusted according to the actual situation. At the same time, conventional adapter plugs do not have an external lead expansion interface, which cannot meet the user's need to extend the power supply point independently. They have the drawbacks of insufficient flexibility and high expansion cost.

[0003] Therefore, there is an urgent need for a new type of plug that can be wired with conversion socket expansion function to solve the above problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a novel plug with a conversion socket expansion function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel plug with a wire extension function includes a plug body, a fixed housing fixed to the outside of the plug body, and a wire extension mechanism. The adapter plug body includes a plug housing and electrical components, with the electrical components fixed inside the plug housing; The wiring extension mechanism includes: a wiring through hole, a plug, and a wiring position; the wiring through hole is opened through the rear side of the plug housing of the fixed housing and the adapter body, and is used to allow external wires to pass into the internal cavity of the plug housing; the plug is detachably embedded and sealed in the wiring through hole; the wiring position is fixedly set in the internal cavity of the plug housing and connected to the conductive circuit of the adapter body, and the wiring position corresponds to the position of the wiring through hole, and is used to achieve electrical connection with the external wires passing through the wiring through hole.

[0006] As a further embodiment of this utility model: the plug housing includes a bottom housing and a top housing, which are detachably connected by bolts. The plug housing is fastened and fixed to the fixed housing to form a rectangular housing. The wiring through hole is formed by a semi-circular through hole one opened at the mating edge of the plug housing and a semi-circular through hole two opened at the mating edge of the fixed housing.

[0007] As a further embodiment of this utility model: the plug is made of insulating elastic material, the outer circumference of the plug is interference-fitted with the inner diameter of the wiring through hole, and the outer end face of the plug is provided with a prying part for easy removal and disassembly.

[0008] As a further embodiment of this utility model: the wiring position includes at least a neutral wire terminal and a live wire terminal, the neutral wire terminal is electrically connected to the neutral wire input pin of the adapter body, and the live wire terminal is electrically connected to the live wire input pin of the adapter body.

[0009] As a further embodiment of this utility model: the wiring position also includes a ground wire terminal, which is electrically connected to the ground input pin of the adapter body.

[0010] As a further embodiment of this utility model: the adapter plug body is provided with at least one power output socket, and the power output socket is connected to the conductive circuit of the adapter plug body.

[0011] As a further embodiment of this utility model: a wire pressing block is fixed inside the plug housing by bolts. The wire pressing block is located between the wiring position and the wiring through hole and is used to assist in wire pressing.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By integrating a conductive wiring structure and a closable cable routing channel into the conventional adapter plug, the problem of traditional adapter plugs being limited to expanding the number of sockets in the original location and unable to flexibly extend the power supply distance is solved. When plugged in, it does not affect the basic function of the original socket. It can both increase the number of available sockets in the original location and extend the power supply point to a distance by connecting external wires, realizing the extension of power supply from a single socket point to multiple areas and long distances, greatly improving the flexibility and spatial adaptability of power supply extension. Users no longer need to worry about insufficient original sockets when using external wire plugs, nor do they need to spend money to buy an additional multi-outlet extension socket or power strip to solve this need, nor do they need to worry about the space-consuming and unsightly problem of adding an extension socket to the original socket. Compared with other extension plugs or power strips, it is more economical and adaptable to different scenarios.

[0013] Second, by supporting users to independently select the length and specifications of external wires, the design solves the problems of fixed wire length, poor scene adaptability, and high overall procurement cost of finished power strips. Users can choose the wire length as needed according to the actual wiring distance and freely arrange the location and number of external sockets without paying extra costs for fixed wire lengths. Compared with finished power strips, it is more economical and adaptable to different scenarios.

[0014] Third, by adopting a split-type shell with a semi-circular groove to form a through hole for wiring, the problem of difficult side opening processing of the one-piece shell and inconvenient internal wire connection operation is solved. This not only reduces the cost of mold development and production processing, but also facilitates the wire threading and wiring operation during assembly, effectively improving production and assembly efficiency.

[0015] Fourth, by configuring a detachable insulating sealing structure to seal the wiring through holes, the safety hazards of exposed internal live structures and easy entry of dust and moisture into the housing are solved in the non-wiring state. Under normal use mode, it can ensure complete insulation protection performance and effectively improve the electrical safety and service life of the product. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In this embodiment of the utility model, please refer to Figures 1 to 7 A novel plug with a conversion socket expansion function is disclosed, comprising a plug body 1, a fixed outer shell 2, and a wiring expansion mechanism. The plug body 1 includes a plug outer shell and internal electrical components 103. The plug outer shell includes a bottom outer shell 101 and a top outer shell 102, which are detachably connected by bolts. The fixed outer shell 2 is fastened to the rear side of the plug body 1. Together, they form a complete rectangular insulating shell, providing protection and insulation for the internal conductive structure. The plug body 1 is provided with input pins for plugging into a wall socket to draw power; the input pins can be three-pronged or two-pronged. At least one power output socket is provided on the top or side of the plug body 1. The output socket is connected to the internal conductive circuit and can directly supply power to electrical equipment, realizing the function of in-situ socket expansion.

[0026] The wiring extension mechanism is located on the rear side of the plug and includes a wiring through hole, a plug 5, and a wiring position 6. The wiring through hole is formed by the mating of a semi-circular through hole 3 and a semi-circular through hole 4: the semi-circular through hole 3 is opened at the mating edge of the plug housing of the adapter body 1 (bottom housing 101), and the semi-circular through hole 4 is opened at the mating edge of the fixed housing 2. When the plug housing and the fixed housing 2 are fastened together, the two semi-circular holes form a complete circular wiring through hole, which runs through the housing from front to back, allowing external wires to pass into the interior of the housing.

[0027] The plug 5 is an elastic plug made of insulating rubber or silicone. Its outer diameter is slightly larger than the inner diameter of the through hole, forming an interference fit. It can be stably embedded in the through hole to seal it. The outer end face of the plug 5 has a protruding prying part, which the user can use to pull the plug 5 out of the through hole and open the wiring channel. The plug 5 can also be connected to the outer wall of the fixed housing 2 by a flexible insulating connecting strip. Even after being pulled out, it remains connected to the plug body to prevent the loss of small parts.

[0028] Wiring point 6 is fixedly installed in the internal cavity of the plug housing, directly opposite the wiring through hole, facilitating direct connection of the inserted wires. Wiring point 6 includes a neutral wire terminal, a live wire terminal, and a ground wire terminal. These three terminals are electrically connected to the neutral, live, and ground input pins of the adapter body 1, respectively, and connected to the main conductive circuit. The terminals adopt a screw crimping structure to fix the core of the external wires, achieving stable electrical conduction.

[0029] The plug housing has a wire clamping block 7 fixed inside by bolts. The wire clamping block 7 is located between the wiring position 6 and the wiring through hole and is used to assist in wire clamping.

[0030] The working principle of this utility model is as follows: In the ordinary adapter plug mode: when there is no need to extend the power supply distance, the plug 5 is embedded and sealed inside the wiring hole to isolate the internal live structure and ensure safe use. At this time, the input pin of the adapter plug body 1 is plugged into the wall socket. Current flows through the input pin into the internal conductive circuit and then supplies power externally through the power output socket on the adapter plug body 1, realizing the conventional socket expansion function and increasing the number of available sockets in the original location.

[0031] Wiring Extension Mode: When extending the power supply point to a distant location, pry open the outer end of the plug 5 to remove it from the wiring through-hole, exposing the internal wiring channel. Insert the prepared external wire through the wiring through-hole into the plug's internal cavity. Crim the neutral, live, and ground wires of the wire onto the corresponding terminals of the wiring position 6, secure them firmly, and then arrange the wire along the wiring through-hole. When the plug is inserted into the wall socket, current is supplied to its own output socket and simultaneously to the external wire through the wiring position 6. The other end of the wire can be connected to an additional socket or electrical device, achieving long-distance power supply extension. Users can choose the wire length according to their actual needs and flexibly arrange the location of the external socket. Compared to pre-made extension sockets and power strips, this method is lower in cost and more adaptable.
