Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wiring terminals, in particular to a wiring terminal for high-speed communication. BACKGROUND

[0002] The wiring terminal is an indispensable basic element in the automobile electrical system, and its core function is to establish reliable and detachable electrical connection between two or more electrical circuits, and to bear the task of current transmission. In the traditional automobile electronic architecture, such as body control, lighting, power distribution and other systems, the signal frequency is low, the data rate is slow, and the main transmission is power or simple control signal.

[0003] With the rapid development of intelligent, networked and electrified vehicles, the vehicle electronic system has undergone revolutionary changes; new technologies such as vehicle driving assistance systems, vehicle infotainment systems, high-resolution cameras, laser radars, and vehicle Ethernet are widely used, resulting in an exponential increase in the amount of data that needs to be transmitted in the vehicle; in the process of automobile manufacturing, the plug-in of the assembly harness and various control units is a key link; at present, this process relies largely on manual operation, and the worker needs to hold the wiring terminal at the end of the harness, align it and insert it into the device interface of the vehicle, and during the plug-in process, the wiring terminal has the risk of being inserted in reverse, and if the wiring terminal for high-speed communication is mistakenly inserted in reverse, there is a serious risk of causing the vehicle to malfunction. SUMMARY

[0004] The purpose of the present application is to overcome the shortcomings of the prior art and provide a wiring terminal for high-speed communication.

[0005] In order to solve the above technical problems, the present application adopts the following technical scheme: The wiring terminal for high-speed communication comprises: An outer shell, which is internally provided with a terminal unit, and is used to support and protect the terminal unit; An elastic unit is arranged inside the outer shell; A lever unit is arranged on the bottom surface of the outer shell, and the lever unit comprises a trigger plate, which can produce a recoverable deformation towards the inside of the outer shell and press the elastic unit when the trigger plate is pressed during the plug-in operation of the outer shell, and at the same time, it will cause instability in holding, and the outer shell will slip off the fingers, and after the pressing is cancelled, the elastic unit will pop the trigger plate back to the original position; During the plug-in operation of the wiring terminal, the worker holds the outer shell in the correct state, and the knuckle of the index finger will contact the limiting plate part of the lever unit, and after the limiting plate is pressed, the limiting plate does not have the ability to press down due to being blocked by the plug, so as to structurally shield the trigger plate and avoid its being mistakenly touched; The above technical solution ensures that when the operator holds the device correctly, both the thumb and forefinger can stably contact the outer casing, allowing the insertion action to be completed smoothly without interference from the lever unit.

[0006] Preferably, both ends of the trigger plate are provided with limiting plates that are parallel to the trigger plate and can move independently.

[0007] Preferably, the elastic unit includes an elastic tube with a hollow interior, plugs fixed inside both ends of the elastic tube, fixing rods on the outer walls of both ends of the elastic tube, and a conduit on the top of the elastic tube.

[0008] Preferably, a connecting unit is connected to the top of the elastic unit inside the outer shell. The connecting unit includes a plate, and a groove is formed at the bottom of the plate, in which the elastic unit is located.

[0009] Preferably, the front surface of the plate has a plurality of wire holes, and the front surface of the plate is also provided with a pin.

[0010] Preferably, the rear surface of the plate is provided with a plug hole, a support block is inserted into one side of the plug hole, the end of the support block is provided with a pin that cooperates with the plug hole, and the bottom of the plate is provided with a hole that cooperates with the guide tube and the hole communicates with the plug hole.

[0011] Preferably, the front end of the outer shell has a through hole, and the support block can reciprocate within the through hole.

[0012] Preferably, the terminal unit includes a shielding shell, a terminal plate is inserted into the outer wall of the shielding shell, a contact pin is inserted into the terminal plate, and the support block can reciprocate inside the shielding shell; the contact pin inserted into the terminal plate is used to contact the automotive equipment interface to realize information transmission; it should be noted that the shielding shell is used to shield external electromagnetic interference and reduce the electromagnetic interference of the external electromagnetic environment of the outer shell to the wiring terminal; it should be noted that when the pin end of the support block is inserted into the plug hole, it first passes through the through hole at the front end of the outer shell, then through the shielding shell, and finally plugs into the plug hole.

[0013] Preferably, one end of the housing is connected to a wire-fixing plate. The surface of the wire-fixing plate has perforations. A cable is disposed on one side of the wire-fixing plate, passing through the perforations and wire holes, and finally connecting to the end of a contact pin. Specifically, during the connection process between the cable and the terminal unit, the cable passes through the wire-fixing plate, then through the wire holes and mating holes of the plate, and finally inserts into the terminal plate. The end of the cable contacts the tail end of the contact pin inside the terminal plate, thus completing the connection between the cable and the terminal unit. The signal is transmitted through the cable and then connected to the automotive equipment interface via the contact pin to achieve signal transmission. The surface of the wire-fixing plate has pin holes, the surface of the plate has pins, and a rod is disposed at the rear end of the housing. A groove is formed on the surface of the wire-fixing plate to mate with the rod. Specifically, during the connection process between the wire-fixing plate and the housing, the wire-fixing plate actively cooperates with the housing for connection. After the rod is inserted into the groove, the pin is also inserted into the pin hole, achieving a stable connection between the housing and the wire-fixing plate. It should be noted that a slanted groove is provided on the bottom surface of the fixed plate near the lever unit. Specifically, the function of the slanted groove is that when the operator holds the outer shell incorrectly, the thumb will press the trigger plate when force is applied. At the same time, in order for the trigger plate to move smoothly into the inner side of the outer shell, the thumb will press into the slanted groove to further provide tactile feedback to the finger.

[0014] Preferably, the outer casing has a main slot and a secondary slot inside, and a plug rod is provided at the tail end of the outer casing. The wire fixing plate has a rod groove that cooperates with the plug rod on the side near the outer casing. During assembly, the top and bottom of the terminal board are inserted into the main slot and the secondary slot, respectively. The main slot and the secondary slot limit the position of the terminal board, ensuring that the terminal board is sufficiently stable inside the outer casing.

[0015] (1) By setting a lever unit on the bottom surface of the outer shell, when the operator holds the outer shell to perform the plugging action, if the thumb accidentally pinches the trigger plate on the bottom surface, the movement of the trigger plate will cause obvious instability and slippage. This structural design is based on ergonomic tactile feedback, which forces the operator to actively adjust the holding posture and switch the thumb to the stable top surface of the outer shell. This ensures the correctness of the direction of the wiring terminal from the source of operation and fundamentally eliminates the risk of vehicle function failure caused by the reverse insertion of the terminal. It also improves the accuracy and efficiency of the plugging operation through intuitive guidance.

[0016] (2) Based on the lever unit structure, an elastic unit is set inside the outer shell above the lever unit. The elastic unit contains an elastic tube. When the trigger plate is squeezed, the middle of the tube can deform and the trigger plate can be reset by its own elasticity after the pressure is removed. The elastic tube has plugs inside both ends. The trigger plate of the lever unit has independent limit plates at both ends. When the outer shell is held correctly for insertion, the knuckle of the operator's index finger naturally presses against the surface of the limit plate. Since the limit plate is blocked by the plug, it does not have the ability to press down, thus structurally shielding the trigger plate and preventing it from being accidentally touched. This design ensures that the thumb and index finger can stably contact the outer shell when held correctly, so that the insertion action is completed smoothly and is not interfered with by the lever unit.

[0017] (3) The present invention further constructs a final anti-misinsertion structure through the linkage of the elastic unit and the connecting unit; when an erroneous grip occurs and the trigger plate is squeezed, the air inside the elastic tube is forced into the connecting unit and pushes the support block on one side of the connecting unit, causing the end of the support block to protrude out of the outer shell; the protruding support block will physically interfere with the device interface, thereby mechanically preventing the terminal contact pin from being inserted during the final insertion stage; this design provides double insurance against misinsertion and greatly enhances the reliability of the connection.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] In the final assembly stage of automobile manufacturing, operators need to manually connect the terminals at the ends of numerous wiring harnesses to the corresponding automotive equipment interfaces. This operation is highly dependent on manual identification and feel, and inherently carries the risk of misoperation. To solve this problem, this application provides the following technical solution: This application provides a high-speed communication terminal block, including: a housing 100, a lever unit 200, an elastic unit 400, and a terminal unit 500; likeFigure 3 As shown, a terminal unit 500 is provided inside the housing 100. The terminal unit 500 is a component that connects to the wiring terminal and external cable (detailed below). like Figure 1 As shown, the top surface of the outer casing 100 is surface A, and its bottom surface is surface B, as follows. Figure 5 As shown, a notch is provided on side B, and a groove is provided at the notch. A lever unit 200 is inserted into one side of the groove. like Figure 6 As shown, the lever unit 200 includes a trigger plate 210, and two independently movable limit plates 220 are provided at both ends of the trigger plate 210. During the automobile production process, when the worker holds the outer shell 100 to perform the plugging action (that is, holds the entire terminal block to perform the plugging action). The normal holding position should be with the thumb and forefinger pinching the outer shell 100, with the thumb in contact with side A and the forefinger in contact with side B (the holding action when plugging in a mobile phone charger). The incorrect grip is with the thumb in contact with side B and the index finger in contact with side A. In an incorrect holding state, if the thumb presses the trigger plate 210 of the lever unit 200, the trigger plate 210 will bend, the thumb and forefinger will lose balance, and the outer shell 100 will slide between the thumb and forefinger, causing the thumb and forefinger to lose their grip on the outer shell 100 or to hold it unsteadily. At this time, when the staff continues to perform the plugging action, it is difficult to align the outer shell 100 with the car equipment interface. The above technical solution, based on ergonomic tactile feedback, forces workers to actively adjust their holding posture, switching their thumbs to the stable top surface of the outer casing. This ensures the correct orientation of the wiring terminals from the source of operation and fundamentally eliminates the risk of vehicle malfunction caused by incorrect wiring terminal insertion. It also improves the accuracy and efficiency of the insertion operation through intuitive guidance.

[0023] When using the lever unit 200 to provide tactile recognition to prevent misinsertion for workers, in order to avoid the lever unit 200 interfering with normal holding and insertion actions, the present invention provides the following technical solution: like Figure 2 , Figure 3 , Figure 4 As shown, a connecting unit 300 is inserted inside the housing 100 on one side of the terminal unit 500; like Figure 7 As shown, the connecting unit 300 includes a plate 310, and a wire hole 340 is formed on the front surface of the plate 310. like Figure 15As shown, the external cable 700 corresponds to the wire hole 340; after inserting the end of the cable 700 into the wire hole 340, it can be connected to the terminal unit 500 (detailed explanation below); like Figure 7 As shown, an elastic unit 400 is inserted into the bottom of the plate 310; like Figure 10 As shown, the elastic unit 400 includes an elastic tube 410, and plugs 440 are inserted into both ends of the elastic tube 410. Specifically, after the trigger plate 210 of the lever unit 200 is squeezed, the trigger plate 210 moves inward toward the outer shell 100. The trigger plate 210 will squeeze the middle area of ​​the elastic tube 410. The elasticity of the elastic tube 410 itself can bounce the trigger plate 210 back to its original position after the pressure is removed, so as to facilitate the automatic reset of the trigger plate 210. During the process of inserting and connecting the terminal blocks, the operator holds the outer casing 100 correctly and inserts the blocks. The knuckle of the index finger will touch the limiting plate 220 of the lever unit 200. After the limiting plate 220 is squeezed, it is blocked by the plug 440 and does not have the ability to press down. Thus, the trigger plate 210 is shielded in the structure to prevent it from being accidentally triggered. The above technical solution ensures that when the operator holds the device correctly, both the thumb and forefinger can stably contact the outer casing 100, allowing the insertion action to be completed smoothly without interference from the lever unit 200.

[0024] Through the above technical solution: it should be noted that a plug plate 230 is connected to the end of the trigger plate 210. The plug plate 230 and the trigger plate 210 are an integral structure. Both the plug plate 230 and the trigger plate 210 are made of insulating plastic material. The plug plate 230 and the trigger plate 210 have different hardness. The plug plate 230 has higher hardness to ensure the stability of the plug plate 230 insertion. The trigger plate 210 has the characteristic of being deformable under pressure. Through the above technical solution: a groove is provided inside the outer shell 100 to cooperate with the insert plate 230. During the installation of the lever unit 200, the insert plate 230 is inserted into the groove, and the insert plate 230 and the groove are tightly fitted to ensure that the insert plate 230 will not arbitrarily detach from the outer shell 100, so as to ensure the connection stability between the entire lever unit 200 and the outer shell 100.

[0025] Through the above technical solution: When relying on the tactile feedback reminder of the lever unit 200, on a busy production line, operators may fail to perceive the tactile prompt of "unstable grip" due to fatigue, rushing to meet deadlines, or wearing thick gloves. They may subconsciously increase their grip strength and forcibly pinch the unstable outer shell 100. If only the "unstable grip" reminder is relied upon, once the operator forcibly pinches and continues the insertion action, this anti-misinsertion structure cannot provide the final, absolute guarantee. The trigger plate 210 can be forcibly pressed all the way down, and the entire terminal may still be incorrectly inserted into the automotive equipment interface. If a power terminal is mistakenly inserted into a signal port, or if a short circuit occurs between the power line and the ground wire, the resulting large current can burn out the connector's metal contacts, melt the cable, or even completely damage the expensive chip in the downstream electronic control unit. This damage is devastating and irreversible. Forcing insertion in the opposite direction applies incorrect stress to the delicate metal pins, causing the fine signal pins on the electronic control unit chip or wiring harness connector to bend, break, or even detach. Even slight bending can lead to poor contact, creating potential problems later. To solve these problems, this invention provides the following technical solution: like Figure 7 , Figure 8 , Figure 9 As shown, the top of the elastic tube 410 is provided with a conduit 420, the rear surface of the plate 310 is provided with a plug hole 330, and the bottom of the plate 310 is provided with a hole that mates with the conduit 420, and the hole communicates with the plug hole 330. like Figure 13 As shown, a support block 530 is inserted into the rear surface of the plate 310, and a pin 5310 is fixed to the end of the support block 530. The end of the pin 5310 is inserted into the insertion hole 330. Through the above technical solution: after the trigger plate 210 is squeezed, the middle part of the elastic tube 410 is squeezed, and the air inside it is discharged from the conduit 420 into the plug hole 330. The air pressure inside the plug hole 330 increases, pushing out the pin 5310, thereby pushing the support block 530 (the support block 530 is inserted from the through hole at the front end of the housing 100 and passes through the terminal unit 500, and the pin 5310 is inserted into the plug hole 330). After the support block 530 is pushed, the end of the support block 530 protrudes outside the front end of the housing 100. During the plugging operation, the part of the support block 530 protruding from the front end of the housing 100 physically interferes with the automotive equipment interface, thereby mechanically preventing the insertion of the terminal contact pin in the final plugging stage. This design provides double insurance against misplugging and greatly enhances the reliability of the connection.

[0026] It should be noted that after the support block 530 is pushed, the wiring terminal needs to be reconnected by hand to push the protruding part back into the housing 100.

[0027] In this invention, such as Figure 8 , Figure 9 As shown, fixing rods 430 are provided on the outer walls of both ends of the elastic tube 410. A groove is provided at the bottom of the plate 310 to cooperate with the fixing rods 430. When the elastic unit 400 is installed below the connecting unit 300, the elastic tube 410 needs to be pushed upward from bottom to top, and then the fixing rods 430 are inserted into the groove, so that the elastic tube 410 is suspended between the connecting unit 300 and the lever unit 200, so as to ensure that the elastic unit 400 maintains its original state under normal and unpressurized conditions.

[0028] like Figure 8 As shown, a mating hole 350 is provided on the rear surface of the plate 310. The wire hole 340 corresponds to the mating hole 350. After the cable 700 passes through the wire hole 340, it will also pass through the mating hole 350. The end of the terminal plate 510 is engaged in the mating hole 350, so that the terminal plate 510 is further secured by the plate 310. The terminal plate 510 and the contact pin inserted therein will be more stable. During the connection of the terminal, the contact pin will not shift in position, and the terminal as a whole is more reliable.

[0029] like Figure 1 As shown, a main slot 110 and a secondary slot 120 are provided on the top and bottom of the inner wall of the outer casing 100. like Figure 11 , Figure 12 As shown, the terminal unit 500 includes a shielding shell 520, and multiple terminal plates 510 are inserted into the outer wall of the shielding shell 520. During the assembly process, the top and bottom of the terminal plates 510 are respectively inserted into the main slot 110 and the sub-slot 120. The terminal board 510 is limited by the main slot 110 and the secondary slot 120 to ensure that the terminal board 510 is sufficiently stable inside the housing 100. like Figure 11 As shown, a contact pin is inserted in the terminal block 510. The contact pin is used to make contact with the automotive equipment interface to realize information transmission. It should be noted that the shielding shell 520 is used to shield external electromagnetic interference and reduce the electromagnetic interference of the external electromagnetic environment of the outer shell 100 to the wiring terminals. It should be noted that during the process of inserting the pin 5310 end of the support block 530 into the insertion hole 330, it first passes through the through hole at the front end of the outer shell 100, then through the shielding shell 520, and finally engages with the insertion hole 330.

[0030] like Figure 14As shown, one end of the outer casing 100 is connected to a cable fixing plate 600, and the surface of the cable fixing plate 600 is provided with a through hole for the cable 700 to pass through. In the process of connecting cable 700 to terminal unit 500, specifically, cable 700 passes through cable fixing plate 600, and then through wire hole 340 and mating hole 350 of plate body 310 (e.g., Figure 8 The cable 700 is inserted into the terminal block 510 (with the wire hole 340 and mating hole 350 shown); the end of the cable 700 contacts the tail end of the contact pin inside the terminal block 510, thereby completing the connection between the cable 700 and the terminal unit 500. The signal is transmitted via cable 700, and then connected to the automotive equipment interface via a contact pin to achieve signal transmission.

[0031] like Figure 16 As shown, the surface of the wire fixing plate 600 is provided with a pin hole 610; as Figure 7 As shown, a pin 320 is provided on the surface of the plate 310; as Figure 1 As shown, a plug rod 130 is provided at the rear end of the outer casing 100, and a rod groove 620 that mates with the plug rod 130 is provided on the surface of the wire fixing plate 600. Specifically, during the connection process between the cable fixing plate 600 and the outer casing 100, the cable fixing plate 600 actively cooperates with the outer casing 100 to connect. After the insertion rod 130 is inserted into the rod groove 620, the pin 320 is also inserted into the pin hole 610, thus achieving a stable connection between the outer casing 100 and the cable fixing plate 600.

[0032] like Figure 17 As shown, it should be noted that this figure shows the B-side of the outer shell 100 and the bottom structure of the wire fixing plate 600. A slanted groove 630 is provided on the bottom surface of the wire fixing plate 600 near the lever unit 200. Specifically, the function of the inclined groove 630 is that when the staff member holds the outer shell 100 incorrectly, the thumb will press the trigger plate 210 when applying force. At the same time, in order for the trigger plate 210 to move smoothly into the inner side of the outer shell 100, the thumb will press into the inclined groove 630 to further provide tactile feedback to the finger.

[0033] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
