Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a connecting terminal, a connector, a wiring harness and a vehicle. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. It is composed of wires, cables, connectors, etc. to realize the transmission of automotive power, signals, etc. Among them, the connector includes two connecting terminals as a male head and a female head respectively, and one end of the two connecting terminals is plugged in. In the field of automotive wiring harness manufacturing technology, the design and manufacture of connecting terminals is an important link, which directly affects the performance and reliability of the wiring harness. In the related technology, one end of the connecting terminal is a contact area electrically connected to the other connecting terminal, and the other end is a crimping area crimped with the wire. Since the material of the connecting terminal body is relatively thin, in order to ensure the crimping holding force between the terminal and the crimping wire, so that the crimping area and the wire are reliably connected, only wires with smaller wire diameters can be used for crimping to ensure the crimping holding force between the connecting terminal and the wire.

In addition, the connection terminal can only be crimped with one wire, so that the current carrying capacity of the connection terminal is limited by the current carrying capacity of the wire, resulting in the connection terminal being unable to carry a large current.

[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0037] According to the first aspect of the present application, the present application provides a connecting terminal 1, see Figure 1 , Figure 2 and Figure 3 , Figure 1 is a schematic diagram of the overall structure of the connection terminal 1 provided in an exemplary embodiment of the present disclosure, Figure 2 is a schematic diagram of the overall structure of the sub-terminal 11 provided in an exemplary embodiment of the present disclosure, Figure 3 yes Figure 2 Enlarged view of point A in the middle. Figure 1 In the embodiment, the wire mating portions 1119 of the two sub-terminals 11 are respectively crimped with the two wires, so the wire mating portions 1119 are in a closed state. Figure 2 In the embodiment, the wire matching portion 1119 of the sub-terminal 11 has not been crimped with the wire and is in an open state.

[0038] The connecting terminal 1 includes a sub-terminal 11. The sub-terminal 11 includes a body 111 and a connecting arm 112. One end of the connecting arm 112 is connected to the body 111, and the other end is a plug-in end 1122. The plug-in end 1122 is provided with a first protrusion 1121. The body 111 is provided with a card hole 1111. The card hole 1111 and the connecting arm 112 are arranged opposite to each other along the width direction of the body 111. One end of the body 111 is configured to be connected to a wire. There are two sub-terminals 11. The two sub-terminals 11 are arranged opposite to each other along the thickness direction of the body 111. The first protrusion 1121 of one sub-terminal 11 is configured to be squeezed by the hole wall of the card hole 1111 of another sub-terminal 11 and elastically deformed, so that the plug-in end 1122 connected thereto can pass through the card hole 1111 of the other sub-terminal 11, or the plug-in end 1122 connected thereto can withdraw from the card hole 1111 of the other sub-terminal 11. The thickness of the body 111 is d0, and the interference between the first protrusion 1121 and the clamping hole 1111 is δE, which satisfies: 20% d0≤δE≤d0. Figure 4 As shown, Figure 4 It is a schematic diagram of the cooperation between the connecting arm 112 and the card hole 1111 provided in an exemplary embodiment of the present disclosure.

[0039] It can be understood that the interference amount between the first protrusion 1121 and the card hole 1111 is δE, including but not limited to 20% d0, 25% d0, 30% d0, 33.3% d0, 35% d0, 40% d0, 45% d0, 52% d0, 60% d0, 66% d0, 70% d0, 75% d0, 78% d0, 80% d0, 90% d0, 96% d0, d0.

[0040] It can be understood that when connecting one sub-terminal 11 with another sub-terminal 11, the connecting arm 112 and the card hole 1111 of one sub-terminal 11 are first arranged opposite to the card hole 1111 and the connecting arm 112 of the other sub-terminal 11, and then the two sub-terminals 11 are moved toward each other so that the plug-in end 1122 of one sub-terminal 11 is inserted into the card hole 1111 of the other sub-terminal 11 until the first protrusion 1121 of one sub-terminal 11 abuts against the body 111 of the other sub-terminal 11. Then, the sub-terminals 11 are pushed with force to apply force toward each other, so that the first protrusion 1121 of one sub-terminal 11 is squeezed by the hole wall of the card hole 1111 of the other sub-terminal 11 and elastically deformed, so that the plug-in end 1122 of one sub-terminal 11 passes through the card hole 1111 of the other sub-terminal 11 as a whole, and the first protrusion 1121 of one sub-terminal 11 passes through the card hole 1111 of the other sub-terminal 11 and cooperates with the body 111 of the other sub-terminal 11 to prevent the plug-in end 1122 of one sub-terminal 11 from falling off from the card hole 1111 of the other sub-terminal 11 at will.

[0041] Correspondingly, when separating the two connected sub-terminals 11, the two sub-terminals 11 are pulled forcefully in the direction away from each other, so that the first protrusion 1121 of one sub-terminal 11 is squeezed by the hole wall of the clamping hole 1111 of the other sub-terminal 11 and elastically deformed, so that the plug-in end 1122 of one sub-terminal 11 is withdrawn from the clamping hole 1111 of the other sub-terminal 11, thereby completing the separation of the two sub-terminals 11.

[0042] Exemplarily, the sub-terminal 11 is an integrally formed part. Specifically, various parts of the sub-terminal 11 are formed by stamping a metal plate, and then bending the metal plate to obtain a Figure 2 The structure of the sub-terminal 11 is shown.

[0043] In this embodiment, two sub-terminals 11 are used to form the connecting terminal 1, so that the connecting terminal 1 can be connected to two wires respectively through the two sub-terminals 11, so that the current transmitted by the connecting terminal can be output by the two wires respectively. In this way, the magnitude of the current that can be transmitted by the connecting terminal 1 can be increased to improve the current carrying capacity of the connecting terminal 1, thereby meeting the demand for large current of electrical equipment such as automobiles.

[0044] In addition, by providing the first protrusion 1121, on the one hand, the first protrusion 1121 can be used to limit the plug-in position between the two sub-terminals 11 to prevent the plug-in end 1122 of one sub-terminal 11 from falling off from the clamping hole 1111 of the other sub-terminal 11 at will, thereby effectively improving the connection reliability between the two sub-terminals 11 to improve the structural stability of the connecting terminal 1; on the other hand, during maintenance, the sub-terminal 11 can be pulled hard to overcome the limitation of the first protrusion 1121 and make the plug-in end 1122 of one sub-terminal 11 fall off from the clamping hole 1111 of the other sub-terminal 11, thereby separating the two sub-terminals 11, thereby ensuring the convenience of maintenance of the connecting terminal 1.

[0045] Furthermore, by limiting the amount of interference between the first protrusion 1121 and the card hole 1111, on the one hand, it can prevent the interference from being too small, causing the plug-in end 1122 to fall off from the card hole 1111 at will, thereby improving the reliability of the connection between the two sub-terminals 11; on the other hand, it can prevent the interference from being too large, causing greater difficulty in installation and disassembly, thereby ensuring the ease of connection and separation of the plug-in end 1122 and the card hole 1111.

[0046] See also Figure 5 and Figure 6 , Figure 5 is a top view of a sub-terminal 11 provided in an exemplary embodiment of the present disclosure, Figure 6 yes Figure 5In some embodiments, the card hole 1111 is a strip-shaped hole. The long diameter direction of the strip-shaped hole is parallel to the length direction of the body 111.

[0047] In this embodiment, by setting the clamping hole 1111 as a strip hole, the area of ​​the mating surface between the clamping hole 1111 and the connecting arm 112 can be increased, thereby improving the stability of the mating between the clamping hole 1111 and the connecting arm 112, and further improving the reliability of the connection between the two sub-terminals 11. By making the major diameter of the strip hole parallel to the length direction of the body 111, it is possible to avoid the strip hole and the connecting arm 112 occupying the space in the middle of the sub-terminal 11, thereby avoiding the interference of the connecting arm 112 with the components around the connecting terminal 1, and further reducing the design difficulty of the connecting terminal 1.

[0048] Specifically, a locking tongue hole 113 may be provided on the body 111, and the locking tongue hole 113 is located between the bar hole and the connecting arm 112. The locking tongue hole 113 is configured to be snap-fitted on the plastic shell. The plastic shell is an insulating shell that at least partially wraps the outer surface of the connecting terminal 1.

[0049] See also Figure 6 In some embodiments, along the width direction of the body 111, the body 111 has a first wide side 1112. The clamping hole 1111 is disposed adjacent to the first wide side 1112. The clamping hole 1111 has a first hole wall 1113 adjacent to the first wide side 1112. The first hole wall 1113 is an arc-shaped surface. The arc-shaped surface is convex toward the first wide side 1112.

[0050] It can be understood that the clamping hole 1111 is formed by a punching process. The longer the punching edge and the larger the punching area, the larger the size of the punching cutter for forming the hole, thereby increasing the strength of the punching cutter, thereby improving the smoothness of material cutting, making the clamping hole 1111 easier to form.

[0051] Based on this, in this embodiment, by convexly setting the first hole wall 1113 toward the first wide side 1112, the perimeter of the clamping hole 1111 can be increased, and the area of ​​the clamping hole 1111 can be increased. In this way, the size of the punching and cutting blade can be increased to improve the strength of the punching and cutting blade. In this way, not only can the clamping hole 1111 be easier to form, but also the practical life of the punching and cutting blade can be increased, the maintenance frequency of the punching and cutting equipment can be reduced, and the forming efficiency can be improved.

[0052] In addition, increasing the circumference of the clamping hole 1111 can also make the punching force on the main body 111 more evenly distributed, so as to reduce local stress concentration.

[0053] See also Figure 5 In some embodiments, the thickness of the body 111 is d0, and the spacing between the first hole wall 1113 and the first wide side 1112 is s, satisfying: d0≤s≤10d0.

[0054] It can be understood that the spacing s between the first hole wall 1113 and the first wide side 1112 includes but is not limited to d0, 1.2d0, 1.5d0, 2d0, 2.7d0, 3d0, 3.4d0, 3.8d0, 4d0, 4.1d0, 4.9d0, 5d0, 5.2d0, 5.6d0, 5.9d0, 6d0, 6.7d0, 7.2d0, 8d0, 8.4d0, 8.8d0, 9d0, 9.1d0, 9.9d0, and 10d0.

[0055] Furthermore, d0≤s≤3d0.

[0056] In this embodiment, through the above definition, there can be a sufficient distance between the first hole wall 1113 and the first wide side 1112 to avoid the low strength of this part and the material flipping after the hole 1111 is punched, thereby ensuring the punching accuracy of the hole 1111.

[0057] See also Figure 4 , Figure 4 1 is a schematic diagram of the connection arm 112 and the locking hole 1111 provided in an exemplary embodiment of the present disclosure. In some embodiments, the thickness of the body 111 is d0, and the interference between the first protrusion 1121 and the locking hole 1111 is δE, which satisfies: 33.3% d0≤δE≤50% d0.

[0058] It can be understood that the interference amount between the first protrusion 1121 and the card hole 1111 is δE, including but not limited to 33.3% d0, 34% d0, 35% d0, 35.5% d0, 37% d0, 38% d0, 40% d0, 41% d0, 40% d0, 42% d0, 43% d0, 44% d0, 45% d0, 46% d0, 46.5% d0, 47% d0, 48% d0, 49% d0, and 50% d0.

[0059] In this embodiment, by further limiting the interference amount between the first protrusion 1121 and the card hole 1111, the reliability of the connection between the two sub-terminals 11 can be improved, and the ease of plugging and separating the plug-in end 1122 and the card hole 1111 can be ensured.

[0060] Clear reference Figure 3 In some embodiments, along the length direction of the body 111 , the first protrusions 1121 are disposed on both sides of the plug-in end 1122 .

[0061] In this embodiment, by arranging the first protrusion 1121 on both sides of the plug-in end 1122, the structural symmetry of the connecting arm 112 can be improved, thereby improving the force symmetry of the connecting arm 112, so that the connecting arm 112 can be more evenly stressed during plugging, thereby reducing poor connection or damage caused by uneven force.

[0062] In another embodiment, along the width direction of the body 111 , the first protrusion 1121 is disposed on one side or both sides of the plug end 1122 .

[0063] A plurality of first protrusions 1121 may be provided on each side of the plug-in end 1122 , and the plurality of first protrusions 1121 are spaced apart along the circumference of the locking hole 1111 .

[0064] See also Figure 3 In some embodiments, the connecting arm 112 has a first end surface 11221 away from the body 111 connected thereto, and at least a portion of the periphery of the first end surface 11221 is provided with a chamfer 11222 .

[0065] Exemplarily, the chamfer 11222 is a chamfer or a rounded corner. Figure 3 The chamfer 11222 shown is a beveled corner.

[0066] In this embodiment, by setting a chamfer 11222 on the first end surface 11221, the plugging of the plug end 1122 and the card hole 1111 can be guided, thereby improving the smoothness of the plugging of the plug end 1122 and the card hole 1111, thereby improving the installation efficiency.

[0067] The distance between the first end surface 11221 and the body 111 penetrated thereby is 0.8d0-1.2d0, specifically d0.

[0068] See also Figure 4 In some embodiments, a stopper 1123 is disposed on the connecting arm 112. The stopper 1123 of one sub-terminal 11 is configured to abut against the body 111 of another sub-terminal 11 after the plug-in end 1122 passes through the card hole 1111.

[0069] In this embodiment, by providing the stopper 1123, the minimum gap between the two sub-terminals 11 can be ensured, so that the connecting terminal 1 can be stably plugged into the male terminal, thereby improving the smoothness of the plugging between the connecting terminal 1 and the male terminal.

[0070] In addition, the distance between the first protrusion 1121 and the stop portion 1123 can be adjusted, and the distance between the two sub-terminals 11 can be adjusted according to the thickness of different male terminals to improve the adaptability of the connecting terminal 1 to the male terminal.

[0071] See also Figure 2 In some embodiments, an anti-error protrusion 1114 is provided on one side in the width direction of the body 111 .

[0072] In this embodiment, by providing the anti-misalignment protrusion 1114, the direction of the connecting terminal 1 can be determined during installation, and installation misalignment can be avoided, thereby improving manufacturing efficiency.

[0073] See also Figure 2 In some embodiments, along the width direction of the body 111 , the side of the anti-error protrusion 1114 away from the body 111 is the first wide side 1112 . The latch hole 1111 is disposed adjacent to the first wide side 1112 .

[0074] In this embodiment, the anti-error protrusion 1114 is arranged adjacent to the card hole 1111, which can enhance the strength of the edge of the main body 111 where the card hole 1111 is arranged, thereby improving the structural strength of the sub-terminal 11, and further improving the reliability of the connection between the sub-terminals 11, thereby improving the structural stability of the connecting terminal 1.

[0075] See also Figure 2 In some embodiments, along the length direction of the body 111, the body 111 includes a contact portion 1115, a connecting portion 1116, a transition portion 1117, a crimping portion 1118 and a wire matching portion 1119 connected in sequence, the connecting arm 112 is connected to the connecting portion 1116, and the clamping hole 1111 is provided in the connecting portion 1116. The crimping portion 1118 is configured to be connected to a wire.

[0076] It can be understood that the parts where the two sub-terminals 11 are connected to the wires are arranged side by side along the width direction of the connection terminal 1. Specifically, along the width direction of the body 111, the transition part 1117, the crimping part 1118 and the wire matching part 1119 are arranged on one side of the connection part 1116. In this way, after the two sub-terminals 11 are connected, the transition part 1117, the crimping part 1118 and the wire matching part 1119 of one sub-terminal 11 and the transition part 1117, the crimping part 1118 and the wire matching part 1119 of the other sub-terminal 11 are arranged side by side along the width direction of the connection terminal 1, thereby improving the compactness of the internal structure of the connection terminal 1 and controlling the overall volume of the connection terminal 1.

[0077] The transition part 1117 is located at one side of the rear end of the connection part 1116 and is connected to the crimping part 1118. The transition part 1117 is arranged asymmetrically, which mainly provides a crimping space for the crimping part 1118, so that the crimping part 1118 can match a wider range of wire diameters. The crimping part 1118 is composed of two wing-shaped structures and a transition arc connecting the two wing-shaped structures. In this way, the crimping part 1118 can wrap the crimped wire, thereby improving the reliability of the crimping between the sub-terminal 11 and the wire.

[0078] It can be understood that the wire is located at the crimping portion 1118 and the wire matching portion 1119. When the connection terminal 1 is connected to the wire, the end of the wire is placed at the crimping portion 1118 and the wire matching portion 1119, and the battery core of the wire contacts the crimping portion 1118. Then, the two sides of the crimping portion 1118 and the wire matching portion 1119 in the width direction are bent around the axis of the wire to make them close to each other, so as to wrap the wire inside and crimp with the wire.

[0079] In addition, a guide portion 1120 is provided on the side of the contact portion 1115 away from the connecting portion 1116, and the guide portions 1120 of the two sub-terminals 11 are arranged opposite to each other in the thickness direction, and along the direction away from the connecting portion 1116, the distance between the guide portions 1120 of the two sub-terminals 11 gradually increases, so that the male terminal can be smoothly inserted between the two sub-terminals 11 through the guide portions 1120.
