Description

Technical Field

[0001] This application relates to conductive connections; structural combinations of a group of mutually insulated electrical connection elements; connection devices; current collectors; and more specifically to the field of electronic products, particularly to an electrical connector and connector assembly. Background Technology

[0002] Electrical connectors, as standardized interface devices for transmitting electrical signals and power, reliably connect different devices, circuits, or cables through the mechanical mating of plugs and sockets, ensuring stable conduction of current, data, or signals between contact points. Connector assemblies, on the other hand, are standardized electrical connection units integrated from multiple cooperating components. While achieving reliable power transmission or signal interaction between devices, they also enhance performance in terms of resistance to environmental interference, prevention of mis-mating, and ease of maintenance. Both are widely used in electronic equipment, industrial control, communication systems, and consumer electronics products.

[0003] Traditional connector assemblies are typically fixed to circuit boards by soldering, crimping, or surface mounting, relying on the printed circuit board as an intermediary. The wires are first soldered onto the printed circuit board, and then the printed circuit board traces are connected to the terminals. However, due to the limitations of the printed circuit board trace width and pad size, it is difficult to optimize the conductive cross-section by increasing the area of ​​the solder pads, which leads to path obstruction during high current transmission and affects charging or high current transmission efficiency. Summary of the Invention

[0004] To address the problem that traditional connector assemblies are limited by circuit board trace width and solder joint size, resulting in obstructed paths and reduced charging or high-current transmission efficiency during high-current transmission, this application provides an electrical connector and connector assembly, employing the following technical solution:

[0005] A connector assembly includes a housing and a connecting shell fixed at one end of the housing. An insulating body first and an insulating body second are fitted inside the housing near the connecting shell. A second connecting terminal is embedded inside the insulating body second. A hook is provided at the top of the second connecting terminal, and a first connecting terminal is provided at the top of the hook. Both the first and second connecting terminals are integrally stamped. One end of each of the first and second connecting terminals has a contact portion. The end of each of the first and second connecting terminals away from the contact portion is a soldering end, and the cross-sectional area of ​​the soldering end is larger than the cross-sectional area of ​​the contact portion.

[0006] By adopting the above technical solution, the first and second connecting terminals, which are integrally stamped, have a larger cross-sectional area at the welding end than at the contact part, which facilitates the optimization of electrical performance. The integral stamping process improves the structural consistency, production efficiency, and strength of the terminals. The larger cross-sectional area at the welding end reduces resistance, reduces energy loss and heat generation during current transmission, and improves the connector's ability to carry high current and its reliability for long-term use. Combined with the dustproof and clamping mechanisms on the shell, the connector achieves excellent physical protection and connection stability on the basis of excellent electrical performance.

[0007] Preferably, the outer shell is symmetrically fixed with barbs at the middle of one end near the connecting shell, and the insulating body one and the insulating body two are each provided with a hook groove adapted to the barb on the opposite side near the outer shell. When the insulating body one and the insulating body two are inserted into the outer shell, the barb and the hook groove are engaged and fixed.

[0008] By adopting the above technical solution, the interlocking structure of the barb and the hook groove enables the rapid fixing of the outer shell to the inner insulating body one and the inner insulating body two, simplifying the assembly process.

[0009] Preferably, the first connecting terminal is provided with a plurality of pre-broken weak parts at intervals in the middle, and the insulating body one and the insulating body two are fixed with a contact post corresponding to the pre-broken weak parts on opposite sides. When the insulating body one and the insulating body two are closed, the contact post squeezes the pre-broken weak parts to break them, thereby separating the first connecting terminal into a plurality of independent electrical pins.

[0010] By adopting the above technical solution, the first connecting terminal is designed as an integral stamped structure with multiple pre-broken weak parts, and corresponding abutting posts are set on the first insulating body and the second insulating body. During the assembly process, the abutting posts squeeze and break the pre-broken weak parts, thereby dividing a continuous metal strip into multiple electrically independent pins. This replaces the complex process of pre-cutting and assembling multiple independent metal sheets one by one, simplifies the production process, and ensures a high degree of consistency in the spacing and position of each pin.

[0011] Preferably, an insulating base is fitted onto one end of the insulating body 1 and the insulating body 2 near the outer shell. Slots are provided on both sides of one end of the insulating base. One end of the hook is movably inserted into the slot. A locking block is fixed on both sides of the end of the insulating body 1 and the insulating body 2 near the outer shell. A locking groove adapted to the locking block is symmetrically opened on the inner side of the end of the insulating base near the insulating body 1 and the insulating body 2, so that the end of the insulating body 1 and the insulating body 2 near the insulating base is locked inside the insulating base.

[0012] By adopting the above technical solution, the hook is inserted into the slot to achieve the functions of movement guidance and limiting. The matching and locking of the card block and the card slot make the first insulating body, the second insulating body, and the first and second connecting terminals inside them an integrated module and positioned inside the insulating base.

[0013] Preferably, guide posts are fixedly provided diagonally on the middle of opposite sides of the insulating body one and the insulating body two. Guide grooves three adapted to the guide posts are opened on opposite sides of the insulating body one and the insulating body two at the guide posts. Wedge-shaped guide blocks are fixedly provided diagonally on opposite sides of the insulating body one and the insulating body two near one end of the outer shell. Guide grooves one adapted to the wedge-shaped guide blocks are opened at corresponding positions of the insulating body one and the insulating body two. A rectangular guide block is fixedly provided at the top of the insulating body two away from the outer shell. A guide groove two adapted to the rectangular guide block is fixedly provided at the rectangular guide block of the insulating body one.

[0014] By adopting the above technical solution, by setting multiple sets of guide blocks of different shapes and corresponding matching guide grooves on the opposite sides of the first insulating body and the second insulating body, the two can achieve precise alignment and guidance in multiple directions and angles when they are assembled together, preventing misalignment or deviation.

[0015] Preferably, the hook has symmetrically provided limiting grooves in the middle, the guide post passes through the limiting groove and is inserted into the guide groove three, the wedge-shaped guide block engages with the guide groove one, and the rectangular guide block engages with the guide groove two, so that the first connecting terminal, the hook and the second connecting terminal are jointly secured between the first insulating body and the second insulating body.

[0016] By adopting the above technical solution, a multi-dimensional mechanical interlocking system is formed by interlocking the limiting groove on the hook with the guide post, and by combining the wedge guide block and the rectangular guide block in the corresponding guide groove. This system precisely constrains and firmly clamps the first connecting terminal, the hook, and the second connecting terminal between the two insulating bodies, preventing the connecting terminals from shifting or loosening due to vibration or frequent insertion and removal during use.

[0017] Preferably, a spring is fixed at one end of the insulating base away from the first insulating body and the second insulating body, and a mating terminal receiving groove is formed at one end of the insulating base near the first insulating body and the second insulating body. The contact portion of the first connecting terminal and the second connecting terminal movably passes through the mating terminal receiving groove. A plurality of solder pads are provided at the top of the first connecting terminal away from the contact portion. A conductive terminal receiving groove is formed at one end of the first insulating body located at the solder pads. The solder pads pass through the conductive terminal receiving groove and extend to the outside of the conductive terminal receiving groove.

[0018] By adopting the above technical solution, the springs on the insulating base provide stable contact pressure for connector insertion, while extending the solder pads of the connection terminals to the outside of the insulating body, ensuring the reliability of electrical connection with the docking equipment and providing a convenient operating interface for wire soldering.

[0019] Preferably, the top of the outer shell is provided with a dustproof mechanism, which includes a fixed shell and a sliding shell disposed on one side of the fixed shell. The fixed shell is fixedly sleeved on the outer side of the outer shell near the connecting shell, and the sliding shell is slidably sleeved on the outer shell away from the connecting shell. A dustproof cover is fixedly provided on the end of the sliding shell away from the fixed shell, and a trigger block is fixedly provided on the outer side of the sliding shell outside the dustproof cover. A plurality of springs are disposed between the fixed shell and the sliding shell. An elastic protective shell is fixedly provided on the opposite side of the fixed shell and the sliding shell, and a push block is symmetrically fixedly provided on the outer side of the sliding shell.

[0020] By adopting the above technical solution, the dustproof mechanism, through the cooperation of the fixed shell and the sliding shell and the elastic connection of the spring and the elastic protective shell, forms a protective component that can slide along the outer shell axis. The dustproof cover, the trigger block and the push block are linked to achieve the dustproof sealing function of automatically opening when plugged in and automatically closing when pulled out.

[0021] Preferably, a clamping mechanism is symmetrically arranged on the outer side of the end of the outer shell away from the dustproof mechanism. The clamping mechanism includes a clamping block and a rotating rod rotatably arranged at one end of the clamping block. One end of the clamping block is provided with an inclined surface adapted to the end of the pushing block. The two ends of the rotating rod are fixedly sleeved with fixing rods fixed to the outer shell. A dustproof sleeve fixed to the fixed shell is fixed on the side of the clamping block near the outer shell. A second spring is provided inside the dustproof sleeve. The two ends of the second spring are respectively fixed to the side of the clamping block near the outer shell and the middle of the outer side of the fixed shell.

[0022] By adopting the above technical solution, the clamping mechanism achieves mechanical coupling with the push block through the design of the inclined surface of the clamping block and the second spring, and automatically completes the clamping and releasing actions during the insertion and removal process, thereby enhancing the pull-out stability of the connector.

[0023] An electrical connector, characterized in that it includes the connector assembly described above, wherein the solder pads of the first connecting terminal and the second connecting terminal are soldered to wires, and the housing is plugged into the interface of an electronic device.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By directly soldering the wires to the soldering ends of the first and second connection terminals, replacing the traditional method of connecting via a circuit board, the current transmission path bypasses the restricted onboard traces, allowing large currents to be directly conducted through a more optimized low-resistance path, reducing energy loss during charging or data transmission, and improving the efficiency of charging or transmitting current, making it easier to carry higher power or more stable signals. 2. During the assembly process, insulating body one and insulating body two are joined together, causing the contact post to break the pre-broken weak part on the first connecting terminal. This separates the originally stamped and integrally formed first connecting terminal into multiple electrically independent pins, enabling a single connector to achieve synchronous connection of multiple signals or power supplies without relying on external circuit boards for electrical separation. This improves production and assembly efficiency and optimizes internal space.

[0025] 3. When the device is inserted, the sliding of the dustproof mechanism and the rotation of the clamping mechanism are triggered in conjunction, so that the dustproof cover opens automatically and the clamping block performs the clamping action. This allows the connector to establish electrical contact while completing physical locking and sealing protection, thereby ensuring the stability of the connection and the cleanliness of the terminals in harsh environments such as vibration and dust, and enhancing the durability and reliability of the entire connector assembly.

[0028] The following is in conjunction with the appendix Figure 1 - Figure 14 This application will be described in further detail.

[0029] This application discloses an electrical connector and a connector assembly.

[0030] Example 1 Reference Figure 1 - Figure 9This application relates to conductive connections; a structural combination of a set of mutually insulated electrical connection elements; a connection device; a current collector; and provides a connector assembly, including a housing 1 and a connecting shell 4 fixed at one end of the housing 1. A barb 15 is symmetrically fixed at the center of the housing 1 near the connecting shell 4. An insulating body 1 5 and an insulating body 2 6 are fitted inside the housing 1 near the connecting shell 4. Hook grooves 16 are provided on the opposite side of the insulating body 1 near the housing 1, and the shape of the hook grooves 16 matches the shape of the barb 15. When the connecting shell 4 and the insulating body 1 5 and the insulating body 2 6 are assembled to the corresponding end of the housing 1, they are secured by the barb 15 and the hook grooves 16. A second connecting terminal 10 is embedded inside the insulating body 2 6. A receiving groove is provided on the side of the insulating body 2 6 facing the insulating body 1 5, and the second connecting terminal 10 is embedded in the receiving groove.

[0031] The top of the second connecting terminal 10 is provided with a hook 11 for locking when the housing 1 is plugged into the device to prevent accidental removal. The top of the hook 11 is provided with a first connecting terminal 9. One end of the first connecting terminal 9 and the second connecting terminal 10 is provided with a contact portion 17. The end of the first connecting terminal 9 and the second connecting terminal 10 away from the contact portion 17 is a soldering end for direct soldering connection to a wire. The cross-sectional area of ​​the soldering end is larger than that of the contact portion 17 to reduce resistance. The top of the first connecting terminal 9 away from the contact portion 17 is provided with multiple solder pads 12, insulating the body. One end of the first connecting terminal 9 is provided with a conductive terminal receiving groove 28 at the pad 12. The pad 12 passes through the conductive terminal receiving groove 28 and extends to the outside of the conductive terminal receiving groove 28. Multiple pre-break weak parts 13 are provided at intervals in the middle of the first connecting terminal 9. Multiple abutting posts 14 are fixed on the opposite side of the insulating body 15 and the insulating body 26 at the pre-break weak parts 13. When the insulating body 15 and the insulating body 26 are closed, the pre-break weak parts 13 are squeezed by the abutting posts 14 and break, thereby dividing the first connecting terminal 9 into multiple independent pins.

[0032] Guide posts 21 are fixed diagonally at the midpoint of opposite sides of the middle of insulating bodies 5 and 6. Guide grooves 26 are formed at the midpoint of opposite sides of the middle ... A wedge-shaped guide block 22 is fixed diagonally on one side of one end. A guide groove 23 is opened at the corresponding position of the insulating body 1 5 and the insulating body 2 6 and the wedge-shaped guide block 22. The wedge-shaped guide block 22 and the guide groove 23 are adapted to each other so that the wedge-shaped guide block 22 is inserted into the guide groove 23. A rectangular guide block 24 is fixed at the top of the insulating body 2 6 away from the outer shell 1. A guide groove 25 is fixed at the rectangular guide block 24 of the insulating body 1 5. The shape of the guide groove 25 is adapted to the shape of the rectangular guide block 24.

[0033] The rectangular guide block 24 is inserted into the second guide groove 25. The cooperation of the guide post 21 with the third guide groove 26, the wedge-shaped guide block 22 with the first guide groove 23, and the rectangular guide block 24 with the second guide groove 25 makes the first connecting terminal 9, the hook 11, and the second connecting terminal 10 secure between the first insulating body 5 and the second insulating body 6. The opposite side of the first connecting terminal 9 and the second connecting terminal 10 abuts against the upper and lower sides of the hook 11. The first insulating body 5 and the second insulating body 6 are both fixed with a locking block 19 on both sides of the end near the outer shell 1. The end of the first insulating body 5 and the second insulating body 6 near the outer shell 1 is fitted with an insulating base 7. The inner side of the insulating base 7 near the end of the first insulating body 5 and the second insulating body 6 is symmetrically provided with a locking groove 18. The locking groove 18 and the locking block 19 are adapted to make the end of the first insulating body 5 and the second insulating body 6 near the insulating base 7 secure to the inside of the insulating base 7.

[0034] A spring piece 8 is fixed at the end of the insulating base 7 away from the insulating body 1 5 and the insulating body 2 6. A docking terminal receiving groove 29 is opened at the end of the insulating base 7 near the insulating body 1 5 and the insulating body 2 6. The contact parts 17 of the first connecting terminal 9 and the second connecting terminal 10 near the insulating base 7 are movably inserted into the docking terminal receiving groove 29. Slots 20 are opened on both sides of the end of the insulating base 7 near the insulating body 1 5 and the insulating body 2 6. The end of the hook 11 near the insulating base 7 is movably inserted into the slot 20. The insulating base 7 is accommodated in the outer shell 1 and is located between the end of the insulating body 1 5 and the insulating body 2 6 and the port of the outer shell 1.

[0035] This electrical connector is suitable for the core component of the plug of an Android data cable. Before use, first, the insulating body 1 5 and the insulating body 2 6 are snapped onto the end of the outer shell 1 near the connecting shell 4. The buckle 15 and the hook groove 16 are used to secure them. Then, the insulating base 7 is put on the insulating body 1 5 and the insulating body 2 6. The insulating base 7 is fixed by the matching of the snap block 19 and the snap groove 18.

[0036] By closing the insulating body 1 5 and the insulating body 2 6, the internal contact post 14 presses the pre-broken weak part 13 of the first connecting terminal 9, causing it to break into multiple independent electrical pins. Through the multiple cooperation of the guide post 21 and the guide groove 3 26, the wedge-shaped guide block 22 and the guide groove 1 23, and the rectangular guide block 24 and the guide groove 2 25, the first connecting terminal 9, the hook 11 and the second connecting terminal 10 are firmly locked between the insulating bodies. At the same time, the two ends of the hook 11 are inserted into the slot 20. When the connector is plugged in, the contact between the spring piece 8 at the front end of the insulating base 7 and the mating terminal establishes a reliable electrical connection between the contact part 17 of the first connecting terminal 9 and the second connecting terminal 10, thereby achieving efficient electrical signal transmission.

[0037] The implementation principle of an electrical connector and connector assembly in this application embodiment is as follows: when the connector is inserted into the interface of an electronic device, the insulating base 7 and the spring 8 guide the contact portion 17 of the first connection terminal 9 and the second connection terminal 10 to align with the device terminal and establish an electrical connection. The multiple independent pins formed by the pre-broken weak portion 13 inside ensure the independent transmission of multiple signals or power.

[0038] Example 2 Reference Figure 10 - Figure 12 , Figure 14 - Figure 16 The top of the outer casing 1 is provided with a dustproof mechanism 2, which is used to prevent dust from entering the interior of the outer casing 1. A clamping mechanism 3 is symmetrically arranged on the outer side of the end of the outer casing 1 away from the dustproof mechanism 2, which is used to clamp and fix the outer casing 1 when it is connected to an electronic product. The dustproof mechanism 2 includes a fixed shell 201 and a sliding shell 202 arranged on one side of the fixed shell 201. The fixed shell 201 is fixedly sleeved on the outer side of the end of the outer casing 1 near the connecting shell 4. The sliding shell 202 is slidably sleeved on the end of the outer casing 1 away from the connecting shell 4. A dustproof cover 204 is fixedly provided on the end of the sliding shell 202 away from the fixed shell 201. The shape of the dustproof cover 204 is adapted to the contour of the end of the insulating body 5 away from the outer casing 1. When the dustproof cover 204 is closed, its inner surface fits and covers the end face of the outer casing 1. The shape of the dustproof cover 204 (e.g., ...) Figure 15As shown), the dust cover 204 is made of flexible rubber material. The dust cover 204 is composed of multiple sheet-like structures of flexible rubber material. A trigger block 203 is fixedly provided on the side of the sliding shell 202 near the dust cover 204. The trigger block 203 slides on the outside of the outer shell 1 and is located on the outside of the dust cover 204.

[0039] Multiple springs 205 are provided between the fixed shell 201 and the sliding shell 202. The two ends of the springs 205 are fixed to the opposite sides of the fixed shell 201 and the sliding shell 202, respectively. An elastic protective shell 206 is fixed to the opposite side of the fixed shell 201 and the sliding shell 202. The elastic protective shell 206 is made of rubber. The elastic protective shell 206 is in a stretched state in the initial state. When the operator inserts the outer shell 1 into the equipment, the equipment pushes the trigger block 203 and the sliding shell 202 to move towards the fixed shell 201, causing the dust cover 204 to deform and open. As the trigger block 203 moves, the elastic protective shell 206 rebounds and is compressed. When the outer shell 1 is separated from the equipment, the sliding shell 202 and the trigger block 203 are reset by the springs 205, which in turn causes the dust cover 204 to reset and close, preventing dust from entering the interior of the outer shell 1. Push blocks 207 are symmetrically fixed at the top and bottom of the sliding shell 202. The end of the push block 207 away from the sliding shell 202 is wedge-shaped.

[0040] The insertion of the outer casing 1 into the device interface causes the trigger block 203 to be pushed, which drives the sliding casing 202 to slide towards the fixed casing 201. This causes the flexible rubber sheet structure of the dust cover 204 to deform and open. At this time, the spring 205 is in a compressed state, and at the same time, the elastic protective casing 206, which is initially in a stretched state, rebounds and is compressed, thereby making room for the connection casing 4 and the end of the internal insulating body 5 to be exposed and connected to the device.

[0041] When the outer casing 1 is pulled out of the device, the spring 205 rebounds and drives the sliding casing 202 and the trigger block 203 to reset, thereby causing the dust cover 204 to return to its original shape and close tightly due to the elasticity of the rubber material. At the same time, the elastic protective casing 206 is stretched again to seal the gap between the fixed casing 201 and the sliding casing 202, preventing external dust from entering the interior of the outer casing 1 and contaminating the terminal contact area.

[0042] Reference Figure 13 , Figure 14 The clamping mechanism 3 includes a clamping block 301 and a rotating rod 302 rotatably disposed at one end of the clamping block 301. The shape of the clamping block 301 is as follows (e.g., Figure 14As shown), when rising, one end of the clamping block 301 has a rotating groove 304, and the rotating rod 302 rotates through the rotating groove 304. Fixed rods 303 are fixedly sleeved at both ends of the rotating rod 302. Rotating holes 305 are opened on both sides of the upper end of the fixed rod 303, and both ends of the rotating rod 302 are fixedly inserted through the rotating holes 305. The bottom end of the fixed rod 303 is fixed to the outer side of the outer shell 1 near the connecting shell 4. The clamping block 301 can rotate around the rotating rod 302 within a certain angle range. A dust cover 306 is fixedly installed on the side of the clamping block 301 near the outer shell 1. The end of the dust cover 306 away from the clamping block 301... The dust cover 306 is fixed to the outer middle of the fixed shell 201. It is made of flexible sealing rubber material. The dust cover 306 has a second spring 307 inside. The two ends of the second spring 307 are fixed to the side of the clamping block 301 near the outer shell 1 and the outer middle of the fixed shell 201, respectively. The clamping block 301 has an inclined surface at the end near the pushing block 207. This inclined surface is adapted to the wedge-shaped inclined surface at the end of the pushing block 207 away from the sliding shell 202. When the pushing block 207 moves with the sliding shell 202, it pushes the clamping block 301 to rotate upward and resets through the second spring 307, thus clamping and fixing the outer shell 1 and the equipment.

[0043] The formula for calculating the elastic force of spring 205 and spring 307 is F=kx, where F represents the spring force, k represents the spring constant, and x represents the spring compression.

[0044] The insertion of the outer casing 1 into the device interface causes the trigger block 203 to drive the push block 207 to slide towards the fixed casing 201. The wedge-shaped inclined surface of the push block 207 contacts the matching inclined surface at one end of the clamping block 301, causing the clamping block 301 to rotate upward around the rotating rod 302. At this time, the second spring 307 is in a stretched state. When the push block 207 slides past one end of the clamping block 301, the second spring 307 rebounds, causing the end of the clamping block 301 to swing inward, thereby fastening it to the device casing and achieving clamping and fixing between the outer casing 1 and the device.

[0045] The first connecting terminal 9 and the second connecting terminal 10 are integrally formed by stamping process, and a pre-broken weak part 13 is punched out on the first connecting terminal 9; the insulating body 1 5, the insulating body 2 6, the insulating base 7, the outer shell 1, the fixed shell 201, the sliding shell 202, the clamping block 301 and the dust cover 204 are obtained by injection molding respectively. Among them, the abutting post 14, the guide post 21, the wedge-shaped guide block 22, the rectangular guide block 24, the guide groove 3 26, the guide groove 1 23, the guide groove 2 25 and the locking block 19 are formed on the insulating body 1 5 and the insulating body 2 6.

[0046] In use, the push trigger block 203 on the end face of the equipment drives the sliding shell 202 to compress the first spring 205 and move towards the fixed shell 201, causing the dust cover 204 to deform and open. At the same time, the push block 207 is driven to abut against the inclined surface of the clamping block 301, causing the clamping block 301 to rotate upward around the rotating rod 302 and stretch the second spring 307. When the push block 207 has completely slid past, the second spring 307 rebounds and causes the lower end of the clamping block 301 to swing inward, thereby firmly clamping its end onto the equipment housing, achieving mechanical locking.

[0047] An electrical connector includes the connector assembly described above, wherein the solder pads 12 of the solder ends of the first connecting terminal 9 and the second connecting terminal 10 are soldered to wires, and the housing 1 is plugged into the interface of an electronic device.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
