Technical Field

Detailed Implementation

[0044] The embodiments of this application will now be described in detail. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0045] The terms "first" and "second" in the specification and claims of this application may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise stated, "multiple" means two or more. Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0046] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0047] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0048] In recent years, with the development of electric vehicles and electronic equipment technologies, the connector industry has also experienced rapid growth. Connectors, through the mating of their male and female terminals, enable the transmission of current or signals, thus achieving their intended functions. When the male and female terminals of a connector are mated, the sound produced during the mating process can be used to determine if the connection is correct; this method is relatively simple and widely applicable. However, in related technologies, the sound emitted by connectors during mating is often quite low, making it difficult for operators to visually determine whether the mating is correct based on the sound alone.

[0049] Based on the above reasons, this application provides a first connector, wherein the first connector disclosed in this application is part of a connector assembly and is used to plug and cooperate with a second connector to realize the transmission of signals or current between the first connector and the second connector. The first connector can be a male end or a female end, and this application does not specifically limit it.

[0050] The first connector provided in the embodiments of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. In the embodiments of this application, the first direction, second direction, third direction, fourth direction, and fifth direction are the directions indicated by arrows D1, D2, D3, D4, and D5 in the figures, respectively.

[0051] like Figures 1 to 8 As shown, the first connector 10 disclosed in this application may include: a body 11 and a locking arm 12. The locking arm 12 is connected to the body 11. The body 11 is used to engage with the second connector 20. After the body 11 and the second connector 20 are engaged, the locking arm 12 is used to lock the first connector 10 and the second connector 20. In addition, when the first connector 10 and the second connector 20 need to be unlocked, the locking of the first connector 10 and the second connector 20 is released.

[0052] Specifically, the body 11 is provided with a gripping part 111 and a plugging part 112. The plugging part 112 is used to plug into the second connector 20. The locking cantilever 12 is connected to the gripping part 111. In practical applications, the operator can operate the gripping part 111 to insert the plugging part 112 into the second connector 20 to achieve the plugging connection between the two.

[0053] Optionally, the locking cantilever 12 includes a first elastic arm 121 and a second elastic arm 122 connected in sequence. The first elastic arm 121 and the second elastic arm 122 form a connection end at the connection point. Since the two are connected to each other, an elastic structure is formed between them. In this way, the second elastic arm 122 can elastically collide with the second connector 20.

[0054] Furthermore, the locking cantilever 12 also includes a bent arm 123 connected between the first elastic arm 121 and the second elastic arm 122. The bent arm 123 is in a bent state. The first elastic arm 121 and the second elastic arm 122 are connected through the bent arm 123. The first elastic arm 121 is connected to the gripping part 111 of the body 11. The bent arm 123 is arranged such that the second elastic arm 122 and the first elastic arm 121 are spaced apart in the first direction. The second elastic arm 122 is used to elastically collide with the second connector 20 during the insertion process and generate a collision sound, so that the operator can intuitively judge whether the first connector 10 and the second connector 20 are properly inserted by the collision sound.

[0055] Optionally, a connecting portion 124 is provided on the first elastic arm 121, the connecting portion 124 extends toward the second elastic arm 122 and is connected to the second elastic arm 122.

[0056] In this embodiment, the first elastic arm 121 and the second elastic arm 122 are connected by a bending arm 123 to form a gap in the first direction, which improves the overall elasticity of the cantilever and increases the collision force of the second elastic arm 122 and the second connector 20, so that the sound generated by the elastic collision can be guaranteed. Furthermore, during the insertion process of the body 11 and the second connector 20, since the first elastic arm 121 is connected to the body 11, the first elastic arm 121 is also provided with a connecting part 124 extending toward and connecting to the second elastic arm 122. The connecting part 124 can provide a certain tension to the second elastic arm 122, thereby ensuring the rigidity of the second elastic arm 122 and preventing the second elastic arm 122 from deforming away from the first elastic arm 121 during production and use, which would reduce the reliability of the elastic collision between the second elastic arm 122 and the second connector 20. The connector provided in this application embodiment ensures the reliability of the collision between the second elastic arm 122 and the second connector 20 during the insertion process of the body 11 and the second connector 20, and increases the sound emitted when the second elastic arm 122 collides with the second connector 20, making it easier for operators to judge the insertion status of the connector by sound.

[0057] Furthermore, it should be noted that since the first elastic arm 121 is connected to the gripping part 111, and the second elastic arm 122 is spaced apart from the first elastic arm 121 along the first direction, the first elastic arm 121 is closer to the second connector 20 along the first direction. In order to ensure that the second elastic arm 122 can elastically collide with the second connector 20, the length of the second elastic arm 122 is greater than the length of the first elastic arm 121. In addition, the second elastic arm 122 can extend above the plug-in part 112 to ensure that the second elastic arm 122 can collide with the second connector 20 after the plug-in part 112 is inserted into the second connector 20.

[0058] like Figure 5 As shown, a support portion 125 is provided at one end of the first elastic arm 121 away from the bent arm 123 along the second direction. The support portion 125 extends toward the body 11 and is connected to the body 11. A connecting portion 124 is provided between the bent arm 123 and the support portion 125 to reduce the unlocking force required to press the locking arm 12. The second direction intersects with the first direction, and the length of the locking arm 12 extends approximately along the second direction.

[0059] Specifically, the connecting part 124 and the supporting part 125 are staggered along the second direction. Since the supporting part 125 extends toward and connects to the body 11, when the locking cantilever 12 is pressed, the locking cantilever 12 rotates with the supporting part 125 as the fulcrum. In practical applications, due to reasons such as inspection, maintenance, or replacement, it may be necessary to disconnect the first connector 10 and the second connector 20. In this embodiment, by placing the connecting part 124 between the bent arm 123 and the supporting part 125, it can be regarded as the connecting part 124 being connected only to the first elastic arm 121 and the second elastic arm 122, but not to the supporting part 125. Therefore, the structural strength of the supporting part 125 is weakened. During the pressing of the locking cantilever 12, the entire locking cantilever 12 rotates not only with the supporting part 125 as the fulcrum, but also with the connecting part 124 as the fulcrum. In this way, the pressing force required to unlock the locking cantilever 12 can be reduced, achieving the effect of saving effort.

[0060] Optionally, along the second direction, the dimension of the connecting part 124 is W1, which satisfies: W1≥0.7mm, so as to take into account both the tension of the second elastic arm 122 and the requirements of the processing technology.

[0061] In practical applications, the first connector 10 can be manufactured using a one-piece molding process, specifically a one-piece injection molding process. By controlling W1 within a reasonable size range, it can be adapted to the one-piece molding process. It should be noted that since the first elastic arm 121 is connected to the body 11, when the locking cantilever 12 is subjected to pressure, the locking cantilever 12 rotates primarily around the support portion 125 as a fulcrum. By reasonably controlling the size of W1, the breakage of the support portion 125 due to the large size of the connecting portion 124 can be avoided.

[0062] Optionally, along the fourth direction, the distance between the bent arm 123 and the support portion 125 is W3, and the distance between the connecting portion 124 and the support portion 125 is L3, satisfying: 0.5mm ≤ L3 < 1 / 2W3. Here, the second direction is the length direction of the locking cantilever, and the fourth direction is the length direction of the main body. A preset angle exists between the fourth direction and the second direction; that is, the locking cantilever 12 is inclined relative to the main body 11.

[0063] In this embodiment, since the connecting part 124 and the supporting part 125 are staggered along the second direction, the locking cantilever 12 as a whole forms a double-fulcrum structure with the supporting part 125 and the connecting part 124 as pressing fulcrums. The smaller the distance L3 between the connecting part 124 and the supporting part 125 along the fourth direction, the greater the required pressing unlocking force. In addition, the smaller the distance W3 between the connecting part 124 and the bent arm 123, the greater the unlocking force required to press the locking cantilever. Therefore, it is necessary to comprehensively consider the pulling force of the connecting part 124 on the second elastic arm 122 and its influence on the pressing unlocking force, and select an appropriate L3 size. When L3 satisfies 0.5mm≤L3<1 / 2W3, the magnitude of the pulling force of the connecting part 124 on the second elastic arm 122 and the pressing unlocking force can be better balanced.

[0064] like Figure 3 , Figure 4 As shown, a support portion 125 is provided at one end of the first elastic arm 121 away from the bent arm 123 along the second direction. The support portion 125 extends toward the body 11 and is connected to the body 11. The connecting portion 124 and the support portion 125 are provided on both sides of the first elastic arm 121 along the first direction. Along the second direction, the size of the connecting portion 124 is W1 and the size of the support portion 125 is W2, which ensures that the first elastic arm 121 is subjected to more uniform force, avoids stress concentration problems caused by size differences, and further reduces the risk of deformation or damage that may occur due to long-term use or external impact.

[0065] The first connector 10 can be manufactured using an integral molding process. In practical applications, to facilitate manufacturing, W1 can be set to W2. It can be understood that setting the dimensions of the support part 125 and the connecting part 124 to be equal can reduce manufacturing difficulty and improve manufacturing efficiency.

[0066] Optionally, the dimension of the connecting part 124 along the third direction is L1, satisfying: W1≥0.7mm, L1≥1.5mm.

[0067] Furthermore, 0.9mm ≤ W1 ≤ 1.2mm, where L1 is also smaller than the dimensions of the first elastic arm 121 and the second elastic arm 122 along a third direction, thereby reducing the pressing force required to press the locking cantilever 12. By controlling W1 to be less than 1.2mm, the pressing force required to unlock the locking cantilever 12 can be reduced; by controlling W1 to be greater than 0.9mm, the breakage of the pressing fulcrum caused by the small size of the connecting part 124W1 is avoided.

[0068] In this embodiment of the application, the first elastic arm 121, the bending arm 123, the second elastic arm 122 and the connecting part 124 surround to form a hollow groove 126, wherein the dimension of the hollow groove 126 along the first direction is Z1 and the dimension of the hollow groove 126 along the second direction is W3, satisfying: Z1≥0.3mm, W3≥0.3mm, and the second direction intersects with the first direction.

[0069] The first elastic arm 121 and the second elastic arm 122 are separate structures with a hollow groove 126 between them. When force is applied to the pressing part 127, since the entire cantilever is divided into the first elastic arm 121 and the second elastic arm 122, an elastic structure is formed between the first elastic arm 121 and the second elastic arm 122. Compared with the integral locking cantilever 12, the elasticity of the locking cantilever 12 is increased, thereby achieving the purpose of saving effort and improving the user's operating experience.

[0070] Optionally, along the first direction, the first elastic arm 121 has a dimension of Z2 and the second elastic arm 122 has a dimension of Z3, satisfying: Z2≥0.6mm, Z3≥0.6mm.

[0071] It should be noted that by reasonably controlling the dimensions of the first elastic arm 121 and the second elastic arm 122 along the first direction, the elasticity of the first elastic arm 121 and the second elastic arm 122 is kept within a reasonable range, and the structural strength is guaranteed, which is beneficial to ensuring the overall stability and reliability of the first connector 10. In practical applications, this dimensional design can also take into account the structural strength and elasticity of the material itself.

[0072] like Figure 10 As shown, the first elastic arm 121 and the central axis of the body 11 have a first preset angle β, which satisfies: 7°≤β≤45°.

[0073] Furthermore, the second elastic arm 122 and the central axis of the body 11 have a second preset angle α. The second preset angle α and the first preset angle β can be equal, i.e., α = β, or they can be unequal. When α = β, the first elastic arm 121 and the second elastic arm 122 are arranged in parallel. When α ≠ β, there is no parallel relationship between the first elastic arm 121 and the second elastic arm 122. This application does not impose specific limitations on this, as long as the overall mechanical strength of the locking cantilever 12 is sufficient to meet the unlocking requirements. Understandably, the smaller β is, the smaller the angle between the first elastic arm 121 and the body 11, and the greater the unlocking force required. When α = β, the angle between the second elastic arm 122 and the body 11 is also small, increasing the difficulty of elastic collision between the second elastic arm 122 and the second connector 20. Therefore, α and β need to be considered comprehensively, taking into account both the magnitude of the unlocking force and the reliability of the collision between the second elastic arm 122 and the second connector 20.

[0074] Optionally, the locking cantilever 12 also includes a pressing part 127, which is connected to the bending arm 123, significantly improving the usability and ease of operation of the first connector 10.

[0075] Specifically, the pressing part 127 is designed to provide the operator with an intuitive and easy-to-use point of leverage, allowing the user to easily unlock or separate the first connector 10 from the second connector 20 by simply pressing the pressing part 127. This design reduces the difficulty of operation and greatly enhances the user experience.

[0076] Furthermore, the pressing part 127 helps improve the overall stability and reliability of the locking cantilever 12. During the insertion process, the pressing part 127 can act as an additional support point, helping the locking cantilever 12 better adapt to and cooperate with the insertion action of the second connector 20, thereby ensuring smooth insertion. At the same time, when subjected to external force, the pressing part 127 can also disperse some stress, reducing deformation or damage to the locking cantilever 12 caused by uneven force, further extending the service life of the first connector 10.

[0077] Optionally, the dimension of the pressing part 127 along the third direction is L2, and the dimension of the pressing part 127 along the second direction is W4, satisfying: L2≥8mm, W4≥5mm, to ensure the comfort and reliability of the user's pressing operation, wherein the first direction, the second direction and the third direction intersect each other.

[0078] Specifically, the pressing part 127 has a dimension L2 of not less than 8mm in the third direction and a dimension W4 of not less than 5mm in the second direction, providing sufficient contact area for the operator and ensuring that the user has enough operating space to easily press the part. This makes it easy for the user to access and operate the pressing part 127, simplifies the connector unlocking process, and improves the convenience of operation.

[0079] Optionally, the end of the second elastic arm 122 away from the bending arm 123 is also provided with a locking part 128, which is used to elastically collide with the second connector 20. Further, the locking part 128 is provided with a limiting hole 1281, which is used to lock the second connector 20.

[0080] Specifically, the locking part 128 is disposed opposite to the second connector 20 along the first direction. The locking part 128 is disposed so that during the insertion process, the second elastic arm 122 not only generates a sound through elastic collision to indicate the insertion status to the user, but also achieves a tighter locking connection through the further contact between the locking part 128 and the second connector 20. This effectively prevents the connector from loosening or falling off due to external force or vibration, thereby ensuring the stability and reliability of the electrical connection.

[0081] In practical applications, the second connector 20 is provided with a limit buckle 21. When the first connector 10 and the second connector 20 are plugged in, the limit hole 1281 can cooperate with the limit buckle 21 to form a physical lock, which enhances the stability of the connection between the two.

[0082] In summary, the first connector provided in this application embodiment has at least the following advantages:

[0083] In this embodiment, the body of the first connector is used to engage with the second connector to achieve the transmission of current and signals between the first and second connectors. The body is also provided with a locking cantilever. Since the locking cantilever and the body are spaced apart along the first direction, during the insertion process between the body and the second connector, the locking cantilever can be used to elastically collide with the second connector and generate a collision sound. In this way, when the operator performs the insertion operation between the first and second connectors, he / she can judge whether the two are properly inserted by the collision sound generated by the locking cantilever and the second connector. This judgment method is more intuitive, not limited by the environment, and has a wider range of applications.

[0084] Secondly, this application also discloses a connector assembly, such as Figure 9 As shown, the connector assembly includes: a second connector 20, and a first connector 10 as described in any of the preceding claims, wherein the first connector 10 is plugged into the second connector 20.

[0085] The locking cantilever 12 of the first connector 10 includes a first elastic arm 121, a bending arm 123, and a second elastic arm 122 connected in sequence. The first elastic arm 121 and the second elastic arm 122 are connected by the bending arm 123 to form a gap in a first direction, which improves the overall elasticity of the cantilever and increases the collision force of the second elastic arm 122 with the second connector 20, so that the sound generated by the elastic collision can be guaranteed. Furthermore, during the insertion process of the body 11 and the second connector 20, since the first elastic arm 121 is connected to the body 11, the first elastic arm 121 is also provided with a connecting part 124 extending toward and connecting to the second elastic arm 122. The connecting part 124 can provide a certain tension to the second elastic arm 122, thereby ensuring the rigidity of the second elastic arm 122 and preventing the second elastic arm 122 from deforming away from the first elastic arm 121 during production and use, which would reduce the reliability of the elastic collision between the second elastic arm 122 and the second connector 20. The connector assembly provided in this application embodiment ensures the reliability of the collision between the second elastic arm 122 and the second connector 20 during the insertion process of the body 11 and the second connector 20, and increases the sound emitted when the second elastic arm 122 collides with the second connector 20, making it easier for operators to judge the insertion status of the connector by sound.

[0086] Specifically, the second connector 20 is provided with a limiting buckle 21 protruding toward the second elastic arm 122. The end of the second elastic arm 122 away from the bent arm 123 along the second direction is also provided with a locking part 128. The locking part 128 is used to elastically collide with the second connector 20. The locking part 128 is provided with a limiting hole 1281, which is used to pass through the limiting buckle 21 to lock the second connector 20.

[0087] Specifically, the second connector 20 has a first surface that mates with the second elastic arm 122, and a limiting buckle 21 is disposed on the first surface and protrudes toward the second elastic arm 122. In practical applications, by providing the limiting buckle 21 on the second connector 20 and providing the limiting hole 1281 on the first connector 10, when the first connector 10 and the second connector 20 are inserted, the cooperation between the limiting hole 1281 and the limiting buckle 21 can form a mechanical locking structure, which enhances the stability and reliability of the connection between the two and provides a strong guarantee for the stable transmission of electrical connections.

[0088] Optionally, when the first connector 10 and the second connector 20 are plugged into each other, the distance between the second elastic arm 122 and the second connector 20 along the fifth direction is L4, which satisfies: 0≤L4≤0.2mm, where the first direction is the height direction of the locking cantilever, the fifth direction is the height direction of the body, and there is a preset angle between the fifth direction and the first direction, that is, the locking cantilever 12 is inclined relative to the body 11.

[0089] Specifically, the locking portion 128 of the second elastic arm 122 can be bent toward the second connector 20 to reduce the distance between it and the first surface of the second connector 20. Further, the second elastic arm 122 has a second surface that mates with the first surface of the second connector 20, wherein the distance between the second surface and the first surface is L2. Understandably, the dimension L2 is related to the distance from the second surface to the central axis of the first connector 10, and the distance Z4 from the first surface of the second connector 20 to the central axis of the second connector 20. In practical applications, the degree of bending of the second elastic arm 122 needs to be determined comprehensively based on the specific dimensions of the second connector 20 and the dimensions of the first connector 10. When the distance L4 between the second elastic arm 122 and the second connector 20 along the fifth direction satisfies 0 ≤ L4 ≤ 0.2 mm, the reliability of elastic collisions between the second elastic arm 122 and the second connector 20 can be improved, thereby ensuring that the operator can judge whether the mating is normal by the mating sound of the first connector 10 and the second connector 20.

[0090] In addition, such as Figure 10As shown, L5 is the insertion distance between the locking part and the second connector. When the first connector is inserted into the second connector, in order to ensure a tight connection between the two, and to ensure that the locking part's limiting hole hits the second connector's limiting buckle during the unlocking process of pressing the locking cantilever, thus preventing the locking from being unlocked, the size of L5 should be increased as much as possible.
