Description
A signal connector device for new energy vehicles Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to a signal connector device for new energy vehicles. Background Technology
[0002] In the field of electrical connections for automotive components, plugs and sockets are common connection methods used to enable signal transmission and power supply between electrical devices.
[0003] In the field of electrical connections for automotive components, existing plug and socket connection technologies typically employ a simple plug-and-play design. Basic sealing measures (such as sealing rings or waterproof tape) prevent moisture ingress, and terminals are secured using simple snap-fit or crimping methods. However, this traditional design has several shortcomings in practical applications. For example, the insertion and extraction forces are relatively high, leading to inconvenience and potential damage to the plug or socket; waterproof performance is limited, making it difficult to effectively resist moisture intrusion in humid environments or water-filled scenarios, potentially causing electrical short circuits or malfunctions; furthermore, the lack of an effective locking mechanism makes it easy for the plug and socket to accidentally disconnect due to misoperation or external force, posing a safety hazard.
[0004] To address the aforementioned shortcomings, a signal connector device for new energy vehicles is provided. Summary of the Invention
[0005] The purpose of this utility model is to provide a signal connector device for new energy vehicles in order to solve the above-mentioned problems.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a new energy vehicle signal connector device, comprising a socket housing, a plug housing, and an electrical connection structure disposed in the socket housing and the plug housing and cooperating therewith, further comprising:
[0007] Cylindrical: Fixed to the side end of the socket housing;
[0008] Handle: Rotatably mounted on the outside of the plug housing via a connecting structure;
[0009] Arc-shaped groove: formed in the handle, when the socket housing and the plug housing are inserted, as the cylinder slides into the arc-shaped groove, rotating the handle drives the socket housing and the plug housing to be inserted.
[0010] Elastic limiting structure: It is provided on the socket housing, which restricts the rotation of the handle to return to its original position when the socket housing and the plug housing are fully connected.
[0011] Preferably, the electrical connection structure includes:
[0012] Pin mechanism: a socket pin disposed in the socket housing, and a socket TPA, a wire plug and a blind plug that are assembled with the socket housing to accommodate the socket pin;
[0013] Spring mechanism: a plug spring disposed in the plug housing, and a plug TPA and a wire plug II that cooperate with the plug housing to assemble the plug spring.
[0014] Preferably, the connection structure includes a round shaft fixed to the side end of the plug housing, and a round hole adapted to the round shaft is formed in the handle.
[0015] Preferably, the handle is provided with a boss, and the elastic limiting structure includes a buckle fixed to the plug housing.
[0016] Preferably, the buckle is deformable within a certain range and returns to its original shape after the external force is removed, and the protrusion has an inclined surface that slides against the buckle.
[0017] Preferably, the socket housing and the plug housing are provided with a multi-level sealing structure.
[0018] Preferably, the multi-stage sealing structure includes a socket sealing ring and a plug sealing ring. The socket housing is integrally formed with a raised rib, the socket sealing ring is arranged on the raised rib, and the plug sealing ring is embedded in the plug housing. When the plug housing is inserted into the socket housing, the socket sealing ring and the plug sealing ring are compressed and undergo elastic deformation to form a sealing layer.
[0019] Preferably, the socket housing is provided with an insert nut, and the socket housing and the insert nut are integrally formed by overmolding.
[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0021] 1. This application utilizes a rotating handle structure to make connecting and disconnecting the plug and socket easier. The arc-shaped trajectory structure, combined with the cylindrical structure of the socket housing, distributes the insertion and extraction force during rotation, significantly reducing the force required for direct insertion and extraction. This design not only improves operational convenience but also reduces the risk of plug or socket damage due to excessive insertion and extraction force, extending the connector's lifespan.
[0022] 2. This application establishes an electrical connection through a mechanical insertion action, where the pin mechanism and spring mechanism cooperate during the insertion process between the plug housing and the socket housing. The barbs and terminal locking structure inside the socket housing ensure the fixation of the socket pins, while the barbs and ribs inside the plug housing fix the plug spring, allowing it to stably engage with the socket pins. This design ensures the stability of signal transmission and power supply, resulting in excellent electrical performance of the connection device and meeting the reliability requirements of automotive components for electrical connections.
[0023] 3. By adopting a multi-level sealing structure, this application significantly improves the waterproof performance of the connection device, enabling it to adapt to humid environments or water-related scenarios, avoiding electrical faults caused by water intrusion, and further enhancing the reliability and service life of the connection device.
[0024] 4. The pre-installation and locking functions implemented by the TPA device in this application improve the assembly efficiency, connection reliability, and maintenance convenience of electrical connectors. The pre-installation function ensures that the terminals remain temporarily fixed during insertion, reducing assembly errors and improving production efficiency; while the locking function enhances the stability of the connection by firmly fixing the terminals, effectively preventing the terminals from loosening due to vibration or external force, thereby improving the reliability of the connector in complex environments.

[0033] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0034] Please refer to Figures 1-6. This utility model provides a technical solution: a signal connector device for new energy vehicles, including a socket housing 1, a plug housing 9, and an electrical connection structure disposed in the socket housing 1 and the plug housing 9 to cooperate with each other, and further including:
[0035] Cylindrical 101: Fixed to the side end of the socket housing 1;
[0036] Handle 8: Rotatably mounted on the outside of the plug housing 9 via a connecting structure;
[0037] Arc groove 802: Formed in handle 8, when socket housing 1 and plug housing 9 are inserted, as cylinder 101 slides into arc groove 802, rotating handle 8 drives socket housing 1 and plug housing 9 to be inserted.
[0038] Elastic limiting structure: It is set on the socket housing 1. When the socket housing 1 and the plug housing 9 are plugged in, it limits the rotation of the handle 8 and resets it.
[0039] During the insertion process, the plug housing 9 aligns with and is inserted into the socket housing 1. At this time, the cylinder 101 on the side of the socket housing 1 gradually slides into the arc-shaped groove 802 on the handle 8. Rotating the handle 8 causes the cylinder 101 inside the arc-shaped groove 802 to gradually push the plug housing 9 closer to the socket housing 1, thus achieving the connection between the plug and the socket. This rotational method reduces the force required for direct insertion and removal by distributing the insertion and removal forces, making the insertion and removal process easier and reducing mechanical impact on the plug and socket.
[0040] The flexible limiting structure ensures that the plug housing 9 and the socket housing 1 will not be accidentally separated due to external force or misoperation after the plug is connected, thus achieving reliable mechanical locking.
[0041] During the insertion of the plug housing 9 into the socket housing 1, the pin mechanism (socket pin 5, socket TPA4, etc.) and the spring mechanism (plug spring 12, plug TPA10, etc.) cooperate to complete the electrical connection. This design establishes the electrical connection through a mechanical insertion action, ensuring the stability of signal transmission and power supply. The combination of electrical connection and mechanical locking ensures that the connection device has reliable mechanical stability while ensuring electrical functionality.
[0042] Specifically, as shown in Figures 3-6, the electrical connection structure includes:
[0043] Pin mechanism: a socket pin 5 disposed in the socket housing 1, and a socket TPA4, a wire plug 6 and a blind plug 7 assembled with the socket housing 1 to assemble the socket pin 5;
[0044] Spring mechanism: a plug spring 12 is provided in the plug housing 9, and a plug TPA 10 and a wire plug 13 are assembled with the plug housing 9 to accommodate the plug spring 12.
[0045] The TPA4 socket engages with the recessed part of the socket housing 1 via a snap-fit mechanism, enabling pre-installation and locking to ensure that the terminals remain in place after insertion. Inside the socket housing 1, barbs are used to secure the socket pins 5. The socket pins 5 are used for electrical connection and are locked in place by the TPA4 socket after insertion into the socket housing 1.
[0046] When the terminal is inserted into the connector but not fully in place, the TPA4 socket is in a pre-installed state. At this time, the latches of the TPA4 socket will press against the protrusion on one side of the socket housing 1, while the other latch will hook into the groove of the socket housing 1, keeping the TPA4 socket in the pre-installed position. Its main purpose is to provide a temporary fixed position during terminal insertion, ensuring that the terminal will not be accidentally dislodged due to external force. This step reduces the time for wire harness manufacturers to insert terminals and improves assembly efficiency. When the terminal is fully inserted, push the TPA4 socket to put it into the locking state. At this time, the latches of the TPA4 socket will hook into the protrusion on the other side of the socket housing 1, ensuring that the terminal is firmly fixed inside the socket.
[0047] The plug housing 9 has barbs inside to fix the plug spring 12. The plug spring 12 is used to make electrical connections with the socket pin 5. The position is fixed by the barbs and ribs inside the plug housing 9.
[0048] Specifically, as shown in Figures 1-4, the connecting structure includes a round shaft 901 fixed to the side of the plug housing 9, and a round hole 801 adapted to the round shaft 901 is formed in the handle 8; a boss 803 is fixed on the handle 8, and the elastic limiting structure includes a buckle 902 fixed on the plug housing 9; the buckle 902 can deform within a certain range and return to its original shape after the external force is removed, and an inclined surface is formed on the boss 803 to slide against the buckle 902.
[0049] When the plug housing 9 is fully inserted into the socket housing 1, the latch 902 on the socket housing 1 engages with the boss 803 on the handle 8. The latch 902 can deform within a certain range and return to its original shape after the external force is removed. When the handle 8 is rotated to the designated position, the latch 902 contacts and slides against the inclined surface on the boss 803, ultimately locking the boss 803 and restricting the reverse rotation of the handle 8.
[0050] To unlock and remove the plug housing 9, a certain external force needs to be applied to overcome the elastic abutment between the latch 902 and the boss 803. When the external force is applied to the handle 8, the latch 902 deforms, and the handle 8 can rotate in the opposite direction, thereby releasing the cylinder 101. After the handle 8 returns to its original position, the plug housing 9 can be smoothly pulled out of the socket housing 1, and the electrical connection is broken. This unlocking mechanism achieves rapid separation through simple mechanical operation, while ensuring the stability of the connection device during normal use.
[0051] Specifically, as shown in Figures 3 and 4, a multi-level sealing structure is provided on the socket housing 1 and the plug housing 9. The multi-level sealing structure includes a socket sealing ring 3 and a plug sealing ring 11. The socket housing 1 has an integrally formed rib, the socket sealing ring 3 is arranged on the rib, and the plug sealing ring 11 is embedded in the plug housing 9. When the plug housing 9 is inserted into the socket housing 1, the socket sealing ring 3 and the plug sealing ring 11 are compressed and undergo elastic deformation to form a sealing layer.
[0052] The socket sealing ring 3 and the plug sealing ring 11 are made of nitrile rubber or fluororubber. Both materials have good oil resistance, abrasion resistance and aging resistance, and can provide a reliable sealing effect in the electrical connections of automotive parts.
[0053] This multi-stage sealing design effectively prevents moisture from entering the connection device, improves waterproof performance, adapts to humid environments or water-related scenarios, and avoids electrical failures caused by moisture intrusion.
[0054] Specifically, as shown in Figure 4, the socket housing 1 is provided with an insert nut 2, and the socket housing 1 and the insert nut 2 are integrated by overmolding.
[0055] The insert nut 2 provides additional mechanical strength and connection reliability to the socket housing 1. Through an overmolding injection molding process, the insert nut 2 is tightly bonded to the socket housing 1, forming a single unit. This structural design effectively prevents the nut from loosening or falling off due to long-term use or external forces, thereby ensuring the long-term stability of the connection device.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
