Description

Technical Field

[0001] This application relates to the technical field of connectors, and in particular to a connector with a flared structure. Background Technology

[0002] In the field of electronic connectors, connectors are core components for circuit connections and are widely used in various electronic devices. As electronic devices become increasingly diversified and personalized, the structural requirements for connectors are also becoming more complex and varied. In different application scenarios, connectors must meet specific requirements for electrical performance, mechanical strength, and spatial layout. However, traditional connector designs often employ standardized structures, with all terminal slots used for inserting terminals to adapt to general applications. But in some special applications, this standardized design reveals significant limitations, failing to flexibly adapt to diverse practical needs.

[0003] In existing technology, a typical connector consists of a female socket, a male plug, and metal terminals. The male plug has four mating parts arranged side-by-side on one side, each with a mounting slot for securing the metal terminals. The female socket has four corresponding slots on one side, each containing a metal pin. In use, the male plug's mating parts are inserted into the female socket's slots, and the metal terminals abut against the metal pins, establishing electrical continuity. This design is widely used in standardized applications, offering advantages such as simple structure and reliable connection, and can meet the connection needs of most electronic devices.

[0004] However, in certain special scenarios, the client may require the number of metal pins on the connector to be less than the number of sockets, for example, retaining only the metal terminals and corresponding metal pins in the two outermost socket sections. In this case, the mounting slots in the two middle socket sections will be idle, becoming channels for dust, moisture, and impurities to enter the connector, affecting the stability of the electronic equipment. To solve this problem, existing technologies typically require redesigning the injection molds for the male plug and female socket for customized production. However, this redesign approach is costly, has a long development cycle, and has room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a connector with a flared structure to solve the problem in the above-mentioned related technologies that the cost and time required to redesign the male plug and female socket in order to meet the customer's requirements (the number of metal pins on the connector is less than the number of sockets).

[0006] The connector with a flared structure provided in this application adopts the following technical solution: A connector with a flared structure includes a female socket, a male plug, and two metal terminals. The male plug has two insertion portions on both sides and two positioning portions in the middle fixed on one side. The female socket has insertion slots for insertion portions and positioning slots for positioning portions on one side. The male plug has through insertion portions and mounting slots for metal terminals to be inserted and fixed on the side away from the insertion portions. The insertion portions and positioning portions have the same outline shape. The positioning portions have positioning slots, and a sealing partition is fixed on the inner wall of the positioning slots.

[0007] By adopting the above technical solution, when the number of metal pins is less than the number of sockets required by customers, there is no need to redesign the entire male plug and female socket structure. The unused middle part can be used as a positioning structure, reducing design and manufacturing costs and shortening the development cycle. At the same time, a sealing partition is set in the positioning slot in the positioning part, which effectively blocks the channels for external dust, moisture, impurities, etc. to enter the connector from the unused area, avoiding the problem of affecting the stability of electronic equipment operation due to contaminant intrusion. It also saves costs, shortens the development cycle, and can better adapt to the market demand for small-batch, rapid delivery.

[0008] Optionally, a positioning insert plate is fixedly provided on the inner wall of the positioning groove, and the positioning insert plate is simultaneously inserted into the positioning groove when the female socket and the male plug are plugged into each other.

[0009] By adopting the above technical solution, a positioning plate is installed on the inner wall of the positioning groove. When the female socket and male plug are inserted, the positioning plate is simultaneously inserted into the positioning groove, which can play a precise positioning role, ensuring that the male plug and female socket are accurately connected and improving connection reliability. At the same time, the positioning plate and the positioning groove cooperate to further enhance the structural stability of the connector after insertion, preventing poor contact caused by shaking during use.

[0010] Optionally, a flared recess is provided on the inner wall of the opening of the mounting through groove away from the insertion part, and a guide slope is provided at the connection between the flared recess and the mounting through groove.

[0011] By adopting the above technical solution, a flared countersunk groove with a guide bevel is opened on the inner wall of the mounting slot opening. When installing metal terminals, the flared countersunk groove increases the opening size, providing more ample insertion space for the metal terminals and facilitating quick positioning. The guide bevel acts as a guide, allowing the metal terminals to be smoothly inserted into the mounting slot along the bevel, reducing insertion difficulty, minimizing terminal damage or improper installation due to improper operation, improving installation efficiency and accuracy, ensuring the stability and reliability of the connector's electrical connection, and enhancing overall performance.

[0012] Optionally, a guide slope is provided on the inner wall of the opening of the flared groove away from the insertion part.

[0013] By adopting the above technical solution, the guide bevel can further optimize the metal terminal insertion process. When the terminal is close to the flared countersunk groove, the guide bevel can more accurately guide the terminal into the groove, making the insertion action smoother, reducing jamming, improving installation convenience and efficiency, and ensuring smooth connector assembly.

[0014] Optionally, a foolproof slot is provided on the guide slope, and a foolproof plug is fixedly provided on the metal terminal. The foolproof plug can be inserted into the foolproof slot after the metal terminal is installed.

[0015] By adopting the above technical solution, the anti-foolproof slot and anti-foolproof plug work together to prevent the metal terminals from being inserted into the mounting slot in the wrong direction or incorrectly, thus avoiding abnormal electrical performance of the connector due to installation errors. This ensures that the metal terminals are installed correctly on the first attempt, improving installation accuracy and efficiency, and guaranteeing stable and reliable operation of the connector.

[0016] Optionally, a limiting plate capable of elastic deformation and resetting is fixed on the inner wall of the mounting groove, and a limiting protrusion is fixed on the side of the limiting plate facing the metal terminal, and a limiting notch is opened on the metal terminal for the limiting protrusion to be engaged.

[0017] By adopting the above technical solution, the limiting plate can elastically deform and return to its original position. When installing metal terminals, the limiting protrusion can engage with the limiting notch, achieving precise positioning and stable fixation, preventing the terminals from loosening and falling off. At the same time, this design requires no complex structure, is easy to install and disassemble, and effectively improves the reliability and stability of the connector connection.

[0018] Optionally, an unlocking protrusion is fixed on the side of the limiting plate facing the mounting slot away from the male plug opening.

[0019] By adopting the above technical solution, the unlocking protrusion is set on a specific side of the limiting plate. When it is necessary to disassemble the metal terminal, the limiting plate can be deformed by pressing the unlocking protrusion, so that the limiting protrusion can be disengaged from the limiting notch, and the terminal can be taken out conveniently and quickly, which improves the convenience and efficiency of connector maintenance and terminal replacement.

[0020] Optionally, a fastener is fixedly provided on the outer surface of the male plug, and a snap fastener is fixedly provided on the outer surface of the female socket to engage with the fastener.

[0021] By adopting the above technical solution, the male plug is equipped with a fastener and the female socket is equipped with a snap fastener. The snap-fit ​​between the two can enhance the stability of the connector after it is plugged in, effectively prevent the male and female sockets from accidentally loosening and separating, ensure the continuous stability of the circuit connection, and the structure is simple and easy to operate. Reliable connection and separation can be achieved without complicated tools.

[0022] In summary, this application includes at least one of the following beneficial technical effects: When meeting customer requirements where the number of metal pins is less than the number of sockets, there is no need to redesign the entire male plug and female socket structure. The unused middle section can be used as a positioning structure, reducing design and manufacturing costs and shortening the development cycle. Simultaneously, a sealing baffle is installed within the positioning slot in the positioning section, effectively blocking external dust, moisture, and impurities from entering the connector from the unused area. This avoids issues such as contaminant intrusion affecting the operational stability of electronic devices, while also saving costs and shortening the development cycle, better adapting to the market demands of small-batch, rapid delivery.

[0025] The present application will be further described in detail below with reference to all the accompanying drawings.

[0026] Example: Reference Figure 1 , Figure 2 A connector with a flared structure includes a female socket 1, a male plug 2, and a metal terminal 3. The female socket 1 and the male plug 2 are injection molded, and the metal terminal 3 is made of metal as a single piece. Two injection molded insertion portions 24 are fixedly arranged side-by-side on one side of the male plug 2, located on both sides, and two injection molded positioning portions 23 are located in the middle. The insertion portions 24 and positioning portions 23 are symmetrically distributed and have the same outline shape. On one side of the female socket 1, insertion slots 15 for insertion of the insertion portions 24 and positioning slots 14 for insertion of the positioning portions 23 are arranged side-by-side.

[0027] The male plug 2 has a through-hole 28 on the side away from the plug part 24, which is for the metal terminal 3 to be inserted and fixed. The female socket 1 has a pin 12 fixed on it, which is inserted into the mounting slot 28 and abuts against the metal terminal 3.

[0028] Insert the metal terminal 3 into the mounting slot 28, and then connect the female socket 1 and the male plug 2. When the female socket 1 and the male plug 2 are connected, the plug part 24 and the positioning part 23 will be inserted into the plug slot 15 and the positioning slot 14 simultaneously. After the female socket 1 and the male plug 2 are connected, the assembly of the connector is completed.

[0029] Reference Figure 2 A fastener 21 is fixedly provided on the outer surface of the male plug 2, and a buckle 11 that engages with the fastener 21 is fixedly provided on the outer surface of the female socket 1. The engagement of the fastener 21 and the buckle 11 strengthens the connection between the female socket 1 and the male plug 2.

[0030] Reference Figure 3 The positioning part 23 is provided with a positioning through groove 22, and a sealing partition 25 is fixedly installed in the positioning through groove 22. A positioning insert 13 is fixedly installed on the inner wall of the positioning groove 14. The positioning insert 13 is inserted into the positioning through groove 22 simultaneously when the female socket 1 and the male plug 2 are plugged into each other.

[0031] The lateral constraint force generated by the positioning plate 13 inserted into the positioning slot 22 can suppress the shaking of the connection and strengthen the connection between the female socket 1 and the male plug 2. The setting of the sealing partition 25 can effectively prevent dust, moisture, impurities and other contaminants from entering the connector while reducing certain development costs, thus ensuring the stability of the electronic equipment operation.

[0032] Reference Figure 4 A flared recess 26 is provided on the inner wall of the opening of the mounting groove 28 away from the plug-in part 24. A guide slope 261 is provided at the connection between the flared recess 26 and the mounting groove 28. A guide slope 262 is provided on the inner wall of the opening of the flared recess 26 away from the plug-in part 24. The guide slope 261 and the guide slope 262 are connected through the flared recess 26.

[0033] The flared recess 26 provides more space for the insertion of the metal terminal 3, making it easier to insert and remove the metal terminal 3. The guide slope 262 and guide slope 261 provide guidance for the metal terminal 3 to be inserted into the mounting slot 28, making it easier for the metal terminal 3 to slide into the correct position.

[0034] A foolproof slot 2611 is provided on the guide slope 261, and a foolproof plug 32 is fixedly provided on the metal terminal 3. After the metal terminal 3 is installed, the foolproof plug 32 can be inserted into the foolproof slot 2611 to prevent the metal terminal 3 from being inserted in reverse.

[0035] Reference Figure 5 A limiting plate 27 capable of elastic deformation and reset is fixed on the inner wall of the mounting groove 28. A limiting protrusion 272 is fixed on the side of the limiting plate 27 facing the metal terminal 3. A limiting notch 31 is opened on the metal terminal 3 for the limiting protrusion 272 to be inserted.

[0036] An unlocking protrusion 271 is fixed on the side of the limiting plate 27 away from the male plug 2. The unlocking protrusion 271 and the limiting protrusion 272 are connected at a certain angle. The unlocking protrusion 271 can drive the limiting protrusion 272 to move to release the fixation of the metal terminal 3.

[0037] The limiting protrusion 272 on the limiting plate 27 serves to fix the metal terminal 3. When it is necessary to remove the metal terminal 3, the unlocking protrusion 271 is moved to drive the limiting protrusion 272 to move, thereby releasing the fixing of the limiting protrusion 272 to the metal terminal 3 and realizing the disassembly of the metal terminal 3.

[0038] The implementation principle of this application embodiment is as follows: When the male plug 2 and the female socket 1 are plugged in, the plug part 24 and the positioning part 23 will be inserted into the plug groove 15 and the positioning groove 14 simultaneously, and the positioning plate 13 will be inserted into the positioning through groove 22 to fix the female socket 1 and the male plug 2. The sealing partition 25 fixed inside the positioning part 23 effectively blocks the penetration of external pollutants. When assembling the metal terminal 3, the flared groove 26 reduces the insertion and extraction resistance by increasing the inlet cross-sectional area. Combined with the double-angle guiding surfaces of the guide slope 261 and the guide slope 262, the terminal contact point slides along a predetermined trajectory. The anti-foolproof slot 2611 and the insertion block have a concave-convex fit to ensure that the metal terminal 3 is inserted in the correct direction; the limiting plate 27 is fixed on the inner wall of the mounting through groove 28, and the limiting protrusion 272 abuts against the limiting notch 31. When unlocking, the unlocking protrusion 271 is moved to drive the limiting protrusion 272 to move, thereby releasing the limiting protrusion 272 from fixing the metal terminal 3 and realizing the disassembly of the metal terminal 3.

[0039] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
