Description

Technical Field

[0001] This utility model relates to the field of socket technology, specifically to an internally integrated adapter socket. Background Technology

[0002] With the increasing frequency of global tourism and business travel, the demand for power conversion equipment among cross-border travelers is becoming more and more urgent. Global travel adapters, as a core product that solves the differences in socket standards between different countries and regions, have become an essential tool for cross-border travel.

[0003] Currently, most universal adapter sockets on the market adopt a decentralized assembly structure design. Their core structural features include: the plug's conductive components, the prongs' conductive components, the universal socket springs, child safety features, and positioning components are all independent, scattered parts, assembled by multiple sets of screws and wire winding connections. This existing technology has the following significant shortcomings:

[0004] 1. The core functional components are designed in a decentralized manner, with a large number of independent parts. During assembly, assembly errors such as component misalignment and loose wire connections are prone to occur, resulting in a decrease in product qualification rate.

[0005] 2. In existing products, the conductive plates of the plugs and the motherboard, as well as the universal socket contacts and the motherboard, are mostly connected indirectly by wires or by simple overlap. During long-term use or plugging and unplugging, the connection points are prone to problems such as poor contact and increased resistance due to vibration and wear. This not only affects the stability of power supply, but may also cause safety hazards such as overheating and short circuits.

[0006] 3. The child safety screens in existing products are mostly installed directly on the outer casing or motherboard, lacking a dedicated positioning and fixing structure. After long-term use, they are prone to displacement and jamming, failing to effectively prevent accidental touch and reducing the safety performance of the product.

[0007] 4. The existing products have complex mating relationships between their internal components and the outer shell. The outer shell needs to be matched with multiple internal components one by one, which limits the design of the outer shell to the internal structure and makes it impossible to flexibly change the shape. At the same time, replacing the outer shell requires disassembling multiple internal fixing structures, which is cumbersome and makes it difficult to meet users' diverse and personalized needs for product appearance. Utility Model Content

[0008] The technical problems to be solved by this utility model are the large number of accessories, the complex assembly process, insufficient electrical conductivity, poor reliability of child protection structure, difficulty in replacing the shell, and monotonous design.

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0010] This utility model proposes an internally integrated adapter socket, comprising a socket body, the socket body including a shell and a middle frame and a face cover sequentially disposed at the opening of the shell, the face cover having multi-gauge sockets, the outer side of the shell having a multi-gauge pin assembly, and the shell containing a main bracket and a main board fixed to the main bracket for realizing circuit conduction and distribution; it also includes:

[0011] The conductive pins are arranged in parallel in the lower part of the main bracket and are attached to the upper and lower sides of the main bracket respectively. The conductive pins extend upward to form contact feet, which pass through the pre-set through holes of the main bracket and are welded to the main bracket to achieve conductive connection.

[0012] A universal socket spring is used to adapt to the insertion and conduction of plugs of different specifications. A child safety bracket is fixed between the universal socket spring and the main board.

[0013] A child safety feature is provided to prevent accidental touch. The child safety feature is installed on the outside of the universal hole spring and is detachably connected to the outside of the child safety plate bracket via a fixing structure.

[0014] Preferably, the child protection component includes a large child protection plate and a small child protection plate arranged vertically. The outer periphery of the child protection plate support is provided with a protruding bone position. The large and small child protection plates are positioned and cooperate with the child protection plate support through the bone position.

[0015] Furthermore, the small child protection plate has a first limiting post on its side end, the large child protection plate has a second limiting post at its bottom, and the outer side of the child protection plate bracket has multiple sets of external limiting grooves. Each of the external limiting grooves has a limiting pin corresponding to the first limiting post and the second limiting post. A spring fixing position is reserved between the first limiting post and the limiting pin, and between the second limiting post and the limiting pin, for fixing the spring.

[0016] Preferably, the universal hole spring is embedded in the child protection film bracket, and the universal hole spring is electrically connected to the motherboard via a connecting wire.

[0017] Preferably, the fixing structure consists of multiple fixing columns evenly distributed on the main support, preferably three fixing columns. The main board has fixing holes that match the fixing columns. The outer side of the child protection bracket is provided with a fixing sleeve, and the fixing columns are inserted into the fixing sleeve to achieve a detachable connection.

[0018] Preferably, the multi-standard pin assembly includes European standard pins, American standard pins, and British standard pins. The bottom of the housing has a U-shaped slot, and the European standard pin is hinged in the slot. The upper and lower sides of the housing are respectively provided with positioning slide grooves. The main bracket is provided with a bone position slide rail that matches the positioning slide groove at the corresponding position. The positioning slide groove is provided with a slidingly connected slide seat outside the positioning slide groove, which drives the American standard pin and the British standard pin to move along the upper and lower positioning slide grooves.

[0019] Preferably, it also includes an interference component, which is fixed to the back end of the main support by a snap-fit ​​structure. The interference component includes a large interference component and a small interference component. The large interference component and the small interference component are provided with a slot. The main support is provided with an elastic snap at the corresponding position. The elastic snap is engaged with the slot to fix the interference component in place and prevent it from falling off.

[0020] Preferably, the main bracket is further provided with a fuse mounting position, and the outer shell is provided with a fuse cover on the outside of the fuse mounting position, the fuse cover being detachably fitted onto the fuse mounting position.

[0021] Preferably, the conductive pin is made of copper alloy, and the contact pin is fixed to the motherboard by soldering; the main bracket is made of ABS flame-retardant plastic, and the surface of the motherboard is provided with an insulating protective layer.

[0022] The present invention proposes an internally integrated conversion socket, and the beneficial effects achieved by adopting the above structure are as follows:

[0023] 1. By using the main bracket as the core support carrier, key components such as the motherboard, conductive sheets, child safety components, and interference devices are integrated into one unit. This eliminates a large number of scattered connectors, reduces assembly steps, improves assembly efficiency, and lowers the assembly error rate, significantly improving the product's pass rate. Furthermore, after the internal components are integrated and fixed, core performance testing can be completed by powering on the entire system, eliminating the need to test each individual component and shortening quality inspection time.

[0024] 2. The internal integrated structure and the outer shell adopt a detachable design. The outer shell only needs to be adapted to the main bracket. There is no need to consider the installation relationship of the internal components. Different materials and shapes of the outer shell can be flexibly designed to meet the personalized needs of users, while also facilitating maintenance.

[0025] 3. The plug's conductive pad is directly soldered to the motherboard, and the pin's conductive pad is soldered and fixed to the motherboard through the upward-extending contact pins passing through the main bracket, achieving a rigid connection between the conductive components and the motherboard. This results in low and stable contact resistance, effectively avoiding the problems of loosening and poor contact that occur with traditional wire connections. At the same time, the child protection component, through bone positioning and spring elastic support, combined with the interfering component's snap-fit ​​fixing structure, ensures that the child protection pad will not shift or get stuck, ensuring reliable anti-accidental touch function and further enhancing the product's safety protection level.

[0026] 4. The components are arranged in layers around the main support, resulting in a compact overall structure. While ensuring multi-functional compatibility, the size of this product is smaller than that of traditional products, making it more portable. Attached Figure Description
