Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a terminal, a connector and a vehicle. Background Art

[0002] Connectors are generally composed of male and female terminals and a plastic shell to form male and female connectors. The terminals are usually inserted into the plastic shell and fixed in the plastic shell by the terminal spring arm structure. When assembled, there is a risk of the terminals loosening. The terminals are formed by stamping and bending strips or sheets, especially at the free end of the terminal lock tongue. When the terminal passes through the hole in the plastic shell, the terminal lock tongue will rub against the edge of the plastic groove, and the terminal lock tongue part will be compressed, causing the lock tongue to yield. When the terminal reaches the stop position, the lock tongue hanging amount is small, resulting in a decrease in the terminal locking force. There are three factors that determine the terminal locking force: 1. The terminal lock hanging amount, 2. The terminal lock tongue structure, and 3. The strength of the plastic body material. Among them, the strength of the plastic material is relatively easy to choose, but the terminal lock tongue structure and the lock hanging amount need to improve the terminal lock strength by improving the structural form. The design of these two places is crucial.

[0003] In the related art, in the existing connector structure, the terminal spring clip generally does not contact the spring arm structure, and the holding force between the terminal and the shell relies on the spring arm structure and the plastic inclined hanging platform. However, the holding force of this part is often small and cannot effectively meet the requirements of the terminal stop position. A terminal secondary lock part (TPA) is often added on the basis of the structure, which not only increases the cost, but also because the terminal and the shell are assembled, there will be a gap. When the gap is too large, there is a risk of movement of the terminal in the shell. When the gap between the terminal and the shell X / Y / Z axis is too large, there will be a hidden danger of electrical performance failure when the product is used in areas with particularly high vibration resistance requirements.

[0041] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0042] Reference below Figure 1-Figure 9 The terminal 100 according to the embodiment of the present invention is described, which can improve the overall structural retention force of the terminal 100, thereby improving the working reliability and stability of the terminal 100.

[0043] Combination Figure 1-Figure 5 As shown, the terminal 100 according to the first embodiment of the utility model includes a plug-in body 1, an anti-retraction elastic arm 2 and a terminal contact elastic arm 3.

[0044] Among them, the plug body 1 is the main structural part of the terminal 100, which is usually made of conductive material (such as copper alloy). One end of the plug body 1 is used to connect with the wire or printed circuit board (PCB), and the other end is used to plug with other terminals 100 or connectors 200 to form an electrical path; the anti-retraction elastic arm 2 has elastic deformation ability, and after the terminal 100 is fully inserted into place, it forms a mechanical lock with the housing 7 or a specific structure (such as a lock or groove) of the connector 200, so as to provide additional gripping force and locking effect, thereby preventing the terminal 100 from accidentally withdrawing due to vibration, impact or temperature changes after being inserted into the housing 7 of the connector 200, thereby ensuring the stability and reliability of the terminal 100 when connected; the terminal contact elastic arm 3 is usually located in the contact area of ​​the plug body 1, which can provide the necessary contact pressure when the terminal 100 contacts the mating terminal 300 to ensure a good electrical connection. In addition, the terminal contact elastic arm 3 has elastic deformation ability, which can be elastically deformed to compensate for manufacturing tolerances, wear or expansion caused by temperature, thereby maintaining stable contact resistance and minimum signal loss. In summary, these three parts are combined together to form a terminal 100 that is both strong and flexible, and can provide reliable electrical connections in different application environments.

[0045] Specifically, the plug-in body 1 is formed with a terminal plug-in slot 11, the anti-retraction elastic arm 2 is connected to the outer periphery of the plug-in body 1, the terminal contact elastic arm 3 is connected to the inner periphery of the plug-in body 1, and the terminal contact elastic arm 3 is located on the side of the anti-retraction elastic arm 2 facing the terminal plug-in slot 11, and the terminal contact elastic arm 3 is abutted and matched with the anti-retraction elastic arm 2.

[0046] Specifically, a terminal plug-in slot 11 for plugging in the matching terminal 300 is formed inside the plug-in body 1, so that the electrical connection effect between the two terminals 100 can be achieved; the anti-retraction elastic arm 2 and the terminal contact elastic arm 3 are respectively connected to the outer periphery and inner periphery of the plug-in body 1, and the terminal contact elastic arm 3 and the anti-retraction elastic arm 2 abut against each other, so that the terminal contact elastic arm 3 can form a holding force on the anti-retraction elastic arm 2, thereby increasing the holding force between the anti-retraction elastic arm 2 and the shell 7, thereby avoiding the risk of the terminal 100 moving and falling off in the shell 7.

[0047] Compared with the traditional connector structure (the terminal contact elastic arm does not contact the anti-retraction elastic arm), the holding force between the terminal and the shell is only maintained by the anti-retraction elastic arm structure and the plastic inclined hanging platform inside the shell, and this part of the holding force is often small, so a terminal secondary lock part (TPA) is usually added on the basis of the original structure. The embodiment in this case can provide additional elastic holding force on the anti-retraction elastic arm 2 while ensuring normal electrical connection through the terminal contact elastic arm 3, thereby effectively enhancing the holding force between the terminal 100 and the shell 7, and avoiding the addition of additional secondary locking parts, thereby reducing manufacturing costs, simplifying the structure, and thus improving the practicality and economy of the connector 200.

[0048] Therefore, by providing the terminal 100 , the overall structural retention force of the terminal 100 can be improved, thereby improving the working reliability and stability of the terminal 100 .

[0049] According to some optional embodiments of the present invention, combined with Figure 2 As shown, the terminal contact elastic arm 3 includes a first elastic section 31 and a second elastic section 32, one end of the first elastic section 31 is connected to the plug-in body 1, one end of the second elastic section 32 is connected to the other end of the first elastic section 31, the second elastic section 32 is bent relative to the first elastic section 31, one of the one end and the other end of the second elastic section 32 is a terminal contact end 321 and the other is an abutment end 322 that abuts against the anti-retraction elastic arm 2.

[0050] In detail, the two ends of the first elastic section 31 are respectively connected to the plug-in body 1 and one end of the second elastic section 32. The second elastic section 32 changes the extension direction of the first elastic section 31. The bent terminal contact elastic arm 3 can provide better elastic recovery ability, and can also help to disperse stress and avoid stress concentration in a single plane, thereby extending the service life of the terminal contact elastic arm 3 and reducing the risk of fatigue fracture; it can also accurately control the contact force to ensure the reliability of the electrical connection and prevent excessive contact force from damaging the connection point; it can also reduce scratches on the plating layer of the mating terminal 300, thereby protecting the surface plating of the mating terminal 300 and extending the service life; the bent terminal contact elastic arm 3 can also better absorb vibration and reduce signal interference in scenarios where high-frequency vibration is required to maintain connection.

[0051] For example, Figure 2 As shown, one end of the second elastic section 32 (that is, the end connected to the first elastic section 31) can be a terminal contact end 321, and the other end of the second elastic section 32 can be an abutment end 322 that abuts against the anti-retraction elastic arm 2. In this way, the terminal contact elastic arm 3 can provide an elastic retaining force to the anti-retraction elastic arm 2, and a normal electrical connection effect can be achieved with the matching terminal 300.

[0052] For another example, one end of the second elastic segment 32 (that is, the end connected to the first elastic segment 31) can be an abutment end 322 that abuts against the anti-retraction elastic arm 2, and the other end of the second elastic segment 32 can be a terminal contact end 321. In this way, on the basis of the terminal contact elastic arm 3 providing an elastic retaining force to the anti-retraction elastic arm 2, a normal electrical connection effect can be achieved with the mating terminal 300.

[0053] Specifically, combined Figure 2 As shown, one end of the second elastic section 32 is a terminal contact end 321 , and the other end of the second elastic section 32 is an abutting end 322 . The terminal contact end 321 is closer to the center of the terminal insertion slot 11 than the abutting end 322 .

[0054] It is understandable that, as arranged above, when the terminal 100 is subjected to stress in the insertion slot, if the terminal contact end 321 is too close to the edge of the terminal contact elastic arm 3, stress concentration may occur, increasing the risk of fracture of the terminal contact elastic arm 3. Designing the terminal contact end 321 closer to the center of the length direction of the terminal contact end 321 can distribute stress more evenly, thereby improving the mechanical strength and durability of the terminal 100. In addition, the terminal contact end 321 is closer to the center of the terminal insertion slot 11 than the abutment end 322, which can enhance the contact stability.

[0055] Furthermore, combined with Figure 2 As shown, the terminal contact elastic arm 3 includes an abutment section 33, the abutment section 33 is connected to the abutment end 322, and the abutment section 33 is bent into an arc or curve relative to the second elastic section 32. Such an arrangement can increase the contact area between the abutment section 33 and the anti-retraction elastic arm 2, thereby more evenly distributing the contact pressure and reducing local hot spots; it can also reduce wear and avoid stress concentration, thereby improving the mechanical strength of the anti-retraction elastic arm 2 and extending the service life and reliability of the connector 200.

[0056] Specifically, combined Figure 2 As shown, the side surface of the terminal contact end 321 facing the center of the terminal insertion slot 11 is constructed as an arc surface. It can be understood that, as arranged above, since the arc surface can provide better self-aligning ability, even if there is a slight deviation when the connector 200 is aligned, the arc surface can ensure a stable electrical connection, thereby improving the contact stability between the terminal contact end 321 and the mating terminal 300 and reducing the poor contact problem caused by size mismatch. Among them, the arc surface design can also optimize the plug-in and pull-out force of the connector 200, making it easier to insert and less likely to be accidentally pulled out, thereby improving the convenience and safety of operation.

[0057] According to some optional embodiments of the present invention, combined with Figure 2As shown, the terminal contact elastic arm 3 is in abutment with the middle of the length direction of the anti-retraction elastic arm 2. Specifically, as arranged above, on the one hand, it can ensure that the terminal contact elastic arm 3 can apply sufficient contact pressure to the anti-retraction elastic arm 2, and on the other hand, it can also avoid the risk of the anti-retraction elastic arm 2 being easily fatigued or broken due to excessive torque on the anti-retraction elastic arm 2, thereby extending the service life of the terminal 100.

[0058] According to some optional embodiments of the present invention, combined with Figure 1 and Figure 2 As shown, there are multiple anti-retraction elastic arms 2 and multiple terminal contact elastic arms 3, and the multiple anti-retraction elastic arms 2 correspond to the multiple terminal contact elastic arms 3 one by one.

[0059] Furthermore, as arranged above, the anti-retraction elastic arm 2 can exert a retaining force on the terminal contact elastic arm 3 in different directions, thereby improving the position stability between the terminal 100 and the housing 7; the anti-retraction elastic arm 2 can also increase the contact point position with the mating terminal 300 in different directions, thereby improving the electrical connection stability between the terminal 100 and the mating terminal 300.

[0060] According to some optional embodiments of the present invention, combined with Figure 1 As shown, the terminal 100 further includes a guide structure 4 , which is connected to the plug-in body 1 and is located in the terminal plug-in slot 11 . The guide structure 4 is used to guide another terminal 100 .

[0061] The guide structure 4 is connected to the plug body 1 as a whole, so that the weight and spatial mode of each other can be increased, thereby improving the structural strength and bending and torsional rigidity of the plug body 1. In addition, the guide structure 4 can be used to guide the assembly path direction of the other terminal 100 of the pair, so as to achieve a smooth connection between the other terminal 100 and the terminal 100, thereby improving the convenience of the terminal 100.

[0062] Specifically, combined Figure 2 As shown, the terminal insertion slot 11 has a notch 111 , and the guide structure 4 includes a plurality of guide flanges 41 , which are configured to be bent relative to the plug-in body 1 in a direction away from the notch 111 , and the plurality of guide flanges 41 are spaced apart in the circumferential direction of the plug-in body 1 .

[0063] It is understandable that, as arranged above, a plurality of guide flanges 41 are spaced apart on the circumference of the plug body 1, so that the guide path of the guide flange 41 can be increased at different positions on the circumference of the plug body 1, thereby improving the guiding smoothness of the guide structure 4 for the mating terminals 300.

[0064] Furthermore, combined with Figure 2As shown, a guide arc surface 411 is formed at the connection between the guide flange 41 and the plug-in body 1. Such an arrangement allows the mating terminal 300 to be smoothly and quickly and accurately inserted under the guidance of the guide arc surface 411, thereby reducing the alignment error of the mating terminal 300 during the assembly process, and can also help to disperse stress, avoid stress concentration on a sharp corner, avoid damage caused by forced insertion, and thus reduce the risk of cracks and fractures caused by stress concentration. In summary, the guide arc surface 411 can ensure that the terminal 100 can be accurately docked, reduce the possibility of poor contact, and protect the terminal 100 from damage.

[0065] According to some optional embodiments of the present invention, combined with Figure 2 As shown, the outer periphery of the plug body 1 forms an anti-mistake portion 12, and the anti-mistake portion 12 and the anti-retraction elastic arm 2 are arranged at intervals in the circumferential direction of the plug body 1. Among them, the anti-mistake portion 12 can prevent the terminal 100 from being installed incorrectly, reduce human installation errors, and improve production efficiency.

[0066] Specifically, the outer cross section of the plug body 1 is a rectangle, and the cross section of the fool-proof portion 12 is a step located at the corner of the rectangle. It can be understood that the fool-proof portion 12 is located at the corner of the plug body 1, which can intuitively produce a visual experience for the user, thereby facilitating the user to play a fool-proof effect in the process of assembling the terminal 100 and improving assembly efficiency.

[0067] According to some optional embodiments of the present invention, combined with Figure 1-Figure 5 As shown, the terminal 100 further includes an intermediate body 5 and a crimping body 6. The intermediate body 5 is connected between the plug-in body 1 and the crimping body 6. Both the intermediate body 5 and the crimping body 6 are provided with crimping pieces that cooperate with the cable.

[0068] Specifically, the intermediate body 5 can be used to support and position other parts of the terminal 100, and can also protect the internal conductive parts to prevent short circuit or electric shock. For example, the intermediate body 5 can be made of insulating materials such as plastic and nylon. The crimping body 6 is a part of the terminal 100 used to connect with the conductor of the wire, and is usually made of conductive metal. The intermediate body 5 and the crimping body 6 are both provided with crimping pieces that cooperate with the cable, so that the intermediate body 5 and the crimping body 6 can be tightly wrapped around the conductor of the wire to ensure a stable contact and low-resistance electrical connection.

[0069] Combination Figure 4 and Figure 5 As shown, the connector 200 according to the second embodiment of the utility model comprises a housing 7 and the terminal 100 of the above embodiment, the terminal 100 is arranged in the housing 7, and the anti-retraction elastic arm 2 cooperates with the housing 7.

[0070] Specifically, the anti-retraction elastic arm 2 on the terminal 100 cooperates with the housing 7 , which can protect the terminal 100 and prevent the risk of the terminal 100 moving or falling off in the housing 7 .

[0071] Optionally, combined Figure 4 and Figure 5 As shown, the distance between the free ends of the anti-retraction elastic arm 2 of the front terminal 100 is set to L1, and at this time there is an assembly gap between the free end of the anti-retraction elastic arm 2 and the shell 7 in both the vertical and horizontal directions; when the connector 200 and the connector 200 are mated with each other, the matching terminal 300 (the cross-sectional length is L0) contacts the abutting end 322 of the terminal contact elastic arm 3 on the terminal 100, and at this time the anti-retraction elastic arm 2 is deformed due to the squeezing of the matching terminal 300, and the abutting section 33 on the terminal contact elastic arm 3 squeezes the anti-retraction elastic arm 2, so that the distance between the free ends of the anti-retraction elastic arm 2 increases, and is set to L2 at this time (at this time L2>L1), so that the vertical gap between the free end of the anti-retraction elastic arm 2 and the shell 7 can be further reduced, and since the anti-retraction elastic arm 2 and the terminal contact elastic arm 3 both have elastic characteristics, zero clearance can be achieved in the vertical direction.

[0072] Furthermore, the terminal 100 is a structure of elastic arms 2 for preventing retreat on four circumferential sides, and the holding force between the terminal 100 and the sheath as a whole can be improved by the abutment section 33 on the terminal contact elastic arm 3. The unlocking process is described below:

[0073] Scenario 1: Combination Figure 6 and Figure 7 , when the terminal 100 and the mating terminal 300 are not assembled

[0074] Model A: The terminal contact elastic arm 3 has an abutment section 33;

[0075] Model B: The terminal contact elastic arm 3 does not have the abutment section 33;

[0076] When the terminal 100 is pulled back, the terminal contacts the elastic arm 3 with the abutment section 33. At this time, the abutment section 33 will support the anti-retraction elastic arm 2 structure, so that when the head of the anti-retraction elastic arm 2 structure touches the inclined hanging platform of the shell 7, the overall structure is not easy to deform. This can indirectly enhance the holding force of the terminal 100. The following is the CAE simulation comparison result of model A and model B: the overall holding force of model A is about 3.8% greater than that of model B as a whole.

[0077] Scenario 2: Combination Figure 8 and Fig. 9 When the terminal 100 is assembled with the mating terminal 300

[0078] Model C: The terminal contact elastic arm 3 has an abutment section 33;

[0079] Model D: The terminal contact elastic arm 3 does not have the abutment section 33;

[0080] When the terminal 100 is pulled backward, when the head of the anti-retraction elastic arm 2 structure touches the inclined hanging platform of the shell 7, since the terminal contact elastic arm 3 is squeezed by the matching terminal 300, the anti-retraction elastic arm 2 structure opens to a larger extent. If the terminal contact elastic arm 3 has an abutment section 33, the abutment section 33 will not only support the elastic arm structure, but also the matching terminal 300 will support the terminal contact elastic arm 3 to make the terminal contact elastic arm 3 less likely to deform as a whole. This can indirectly enhance the holding force of the terminal 100. The following is the CAE simulation comparison result of the C model and the D model: the overall holding force of the D model is about 12% greater than that of the C model as a whole.

[0081] The vehicle according to the embodiment of the third aspect of the utility model comprises the connector 200 of the above embodiment. The vehicle having the connector 200 can ensure the working stability and reliability of the connector 200, thereby improving the market competitiveness of the vehicle.
