Specific details for implementing the invention

[0031] Embodiments of the present application are described in detail below. The embodiments described with reference to the attached drawings are examples. A contact (100) for a first connector (200) according to one embodiment of the first aspect of the present application is described below with reference to FIGS. 1 to 6.

[0032] As illustrated in FIGS. 1 and FIGS. 4, according to one embodiment of the first aspect of the present application, a contact (100) for a first connector (200) includes a main body (1).

[0033] Specifically, the main body (1) has a locking surface (111). The locking surface (111) is configured not to face the front position (e.g., the dotted line position indicated by arrow A in FIG. 1) when locked with the housing (201) of the first connector (200). For example, in the examples of FIG. 1 and FIG. 4, the locking surface (111) is located at the upper right end of the main body (1). When the contact (100) is mated with the housing (201), the locking surface (111) cooperates with the inner wall surface of the housing (201) to lock the contact (100) to the housing (201). When the contact (100) is assembled with the housing (201), the main body (1) of the contact (100) is inserted into the interior of the housing (201). After the locking surface (111) is locked to the housing (201), a pulling force is applied to the main body (1) in the right direction (i.e., opposite to the insertion direction of the main body (1)) to generate a pair of action and reaction forces between the locking surface (111) and the inner wall surface of the housing (201) to detect whether the lock is in place. The locking surface (111) is configured so as not to face the shear position when locked to the housing (201) of the first connector (200), that is, the locking surface (111) is not laterally opposed to the shear position, thereby reducing the action force ("action force" refers to the shear force applied by the locking surface (111) to the inner wall surface of the housing (201). As a result, the likelihood of the locking surface (111) penetrating the housing (201) is reduced, effectively preventing the main body (1) of the contact (100) from detaching from the housing (201) after penetrating the housing (201), improving the assembly stability of the contact (100) and the housing (201), and further enhancing the usage stability of the first connector (200). Additionally, the housing (201) of the first connector (200) is advantageous for normal use for a long time, thereby extending the service life of the first connector (200).

[0034] For example, in the example of the present application, as shown in FIG. 1, when the locking surface (111) applies a force to the inner wall surface of the housing (201), the aforementioned shear position is the position of the housing (201) that is prone to breaking, i.e., the dotted line position indicated by arrow A in FIG. 1. The aforementioned dotted line position is located on the contact surface between the locking surface (111) and the inner wall surface of the housing (201) to reduce the force of the locking surface (111) on the inner wall surface of the housing (201). When the position of the housing (201) that is prone to breaking is facing the locking surface (111) in the left and right directions, the housing (201) is more likely to break at the breaking position under the force of the locking surface (111), i.e., the main body (1) is more likely to detach from the inside of the housing (201).

[0035] According to the contact (100) for the first connector (200) in the present application, by configuring the locking surface (111) so as not to face the shear position when locked with the housing (201) of the first connector (200), the force exerted by the locking surface (111) on the inner wall surface of the housing (201) is reduced. As a result, the likelihood of the locking surface (111) penetrating the housing (201) is reduced, thereby preventing the main body (1) of the contact (100) from detaching from the housing (201), improving the assembly stability of the contact (100) and the housing (201), and further enhancing the service stability of the first connector (200). Additionally, the service life of the first connector (200) is also extended.

[0036] According to some embodiments of the present application, with reference to FIGS. 1 and FIGS. 4, the shear position is located on one side of the locking surface (111) away from the center of the main body (1). For example, in the examples of FIGS. 1 and FIGS. 4, the shear position is located on the locking surface (111). According to this arrangement, during the process in which the locking surface (111) applies force to the housing (201), the housing (201) is less likely to break at the shear position, the housing (201) is less likely to be damaged, and the main body (1) is less likely to detach from the housing (201), thereby extending the service life of the housing (201) and further improving the service stability of the first connector (200).

[0037] According to some embodiments of the present application, with reference to FIG. 1, the housing (201) has a contact surface (2011). When the locking surface (111) is locked to the housing (201), the locking surface (111) comes into contact with the contact surface (2011), and the locking surface (111) is parallel to the contact surface (2011). For example, in the example of FIG. 1, the locking surface (111) and the contact surface (2011) are opposite each other along the axial direction of the main body (i.e., the left-right direction of FIG. 1). When a rightward force is applied to the main body (1), the main body (1) moves to the right until the locking surface (111) comes into contact with the contact surface (2011) (as shown in FIG. 2). In this way, the contact surface (2011) restricts the locking surface (111) and restricts further rightward movement of the main body (1), thereby preventing the main body (1) from being removed from the housing (201). Additionally, by configuring the locking surface (111) parallel to the contact surface (2011), the force exerted by the locking surface (111) on the contact surface (2011) can be effectively reduced, thereby reducing the shear force exerted by the locking surface (111) on the housing (201) and preventing the locking surface (111) from penetrating the inner wall surface of the housing (201) and subsequently being removed from the housing (201). Furthermore, it is effectively ensured that the locking surface (111) does not face the shear position when locked with the housing (201), thereby further preventing the main body (1) from being removed from the housing (201).

[0038] According to some embodiments of the present application, with reference to FIG. 4, a locking portion (11) is provided on the main body (1). The locking portion (11) has a locking surface (111). One end of the locking portion (11) is connected to the main body (1), and the other end of the locking portion (11) extends obliquely in a direction away from the central axis of the main body (1). The locking surface (111) is located at the other end of the locking portion (11). For example, in the example of FIG. 4, the left end of the locking portion (11) is connected to the main body (1), the right end of the locking portion (11) extends obliquely upward, and the locking surface (111) is located at the right end end face of the locking portion (11). According to this arrangement, the locking portion (11) can be tilted upward, which facilitates the locking portion (11) to be locked to the housing (201), thereby improving the usability of the main body (1). Additionally, the locking part (11) has a simple structure and is easy to manufacture, which can reduce the production cost of the locking part (11). It should be noted that the length of the locking surface (111) in a direction perpendicular to the central axis of the main body (1) (i.e., the up and down direction in FIG. 4) and the length of the locking surface (111) in the direction of the central axis of the main body (1) can be determined based on the gap between the upper cutting edge (13) and the lower cutting edge (14) of the stamping die and the sharpness of the cutting edge (shown in FIG. 5), which is beneficial for controlling the formation of the locking surface (111).

[0039] Referring to FIGS. 2 and 3, the angle of inclination of the locking part (11) is C, the angle of inclination between the locking surface (111) and the cross-section of the locking part (11) (i.e., the angle of inclination between the locking surface (111) and the plane in which the thickness direction of the locking part (11) is located) is B, the length of the locking surface (111) in the direction perpendicular to the central axis of the main body (1) is H, the length of the locking surface (111) in the direction of the central axis of the main body (1) is W, and the force applied by the other end of the locking part (11) to the housing (201) is F ("force F" refers to the shear force applied by the end of the locking part (11) to the contact surface (2011) of the housing (201). Here, C, B, H, W, and F satisfy: B = arctan(W / H), and F ∝ 1 / Sin(B+C).

[0040] For example, the interlocking angle (B) between the locking surface (111) and the cross-section of the locking part (11) is proportional to the ratio (i.e., W / H) of the length (W) of the locking surface (111) in the direction of the central axis of the main body (1) to the length (H) of the locking surface (111) in the direction perpendicular to the central axis of the main body (1). That is, the ratio (i.e., W / H) of the length (W) of the locking surface (111) in the direction of the central axis of the main body (1) to the length (H) of the locking surface (111) in the direction perpendicular to the central axis of the main body (1) is small. Accordingly, the value of the interlocking angle (B) between the locking surface (111) and the locking part (11) can be adjusted by using the length (H) of the locking surface (111) in a direction perpendicular to the central axis of the main body (1) and the length (W) of the locking surface (111) in the direction of the central axis of the main body (1).

[0041] For example, the force (F) applied by the other end of the locking part (11) to the housing (201) is inversely proportional to Sin(B+C). The force (F) applied by the other end of the locking part (11) to the housing (201) is inversely proportional to the angle of inclination (C) between the locking surface (111) and the cross-section of the locking part (11) or the angle of inclination (C) of the locking part (11). That is, when the angle of inclination (C) of the locking part (11) does not change, the larger the angle of inclination (B) between the locking surface (111) and the cross-section of the locking part (11), the smaller the force (F) applied by the other end of the locking part (11) to the housing (201). When the interlocking angle (B) between the locking surface (111) and the cross-section of the locking part (11) does not change, the greater the inclination angle (C) of the locking part (11), the smaller the acting force (F) applied by the other end of the locking part (11) to the housing (201). Therefore, by changing the interlocking angle (B) between the locking surface (111) and the cross-section of the locking part (11) or the inclination angle (C) of the locking part (11), the acting force (F) applied by the other end of the locking part (11) to the housing (201) can be reduced, thereby preventing the housing (201) from being penetrated by an excessively large acting force (F) and further preventing the main body (1) of the contact (100) from being detached from the housing (201).

[0042] Through practical verification, the results correspond to the theory as shown in the table below. From the data in the table, it can be learned that the locking part (11) of the new structure provided with the locking surface (111) exhibits a greater retaining force against the housing (201). That is, the structure of this solution can withstand a greater applied force, and the main body (1) is less likely to detach from the housing (201). In addition, by providing the position limiting projection (1221) described later, the locking part (11) can maintain a higher height after the main body (1) of this solution is inserted into the housing (201), thereby effectively solving the problem where the locking part (11) is pressed downward and fails to elastically rebound during the process of inserting the main body (1) into the housing (201). It should be noted that "the retaining force of the locking part against the housing" refers to the magnitude of the external force that the main body (1) can withstand when the main body (1) receives an external force. The old structure refers to a structure that does not have the locking surface (111) of the present application.

[0043]

[0044] Optionally, with reference to FIG. 3, the interlocking angle (B) between the locking surface (111) and the cross-section of the locking part (11) is B, where B satisfies: 30° ≤ B ≤ 60°. For example, when the interlocking angle (B) between the locking surface (111) and the cross-section of the locking part (11) is less than 30°, the interlocking angle (B) between the locking surface (111) and the cross-section of the locking part (11) is relatively small, resulting in a greater force (F) applied by the other end of the locking part (11) to the housing (201). Consequently, the likelihood of the locking part (11) penetrating the housing (201) increases, and the likelihood of the main body (1) of the contact (100) detaching from the housing (201) increases, thereby reducing the stability of use of the first connector (200). When the interlocking angle (B) between the locking surface (111) and the cross-section of the locking part (11) is greater than 60°, the interlocking angle (B) between the locking surface (111) and the cross-section of the locking part (11) is relatively large, and the locking surface (111) tends to be on the same plane as one side of the locking part (11) that is close to the center of the main body (1) (i.e., the axial direction of the main body (1)). This increases the force exerted by the locking part (11) on the contact surface (2011), and increases the likelihood that the inner wall surface of the housing (201) will be damaged when the main body (1) is pulled to the right. Accordingly, by configuring the interlocking angle (B) between the locking surface (111) and the cross-section of the locking part (11) to satisfy 30° ≤ B ≤ 60°, and through the appropriate setting of the interlocking angle (B) between the locking surface (111) and the cross-section of the locking part (11), the force (F) applied by the other end of the locking part (11) to the housing (201) is small, so there is less chance of the locking part (11) penetrating the housing (201), and the main body (1) of the contact (100) is prevented from easily detaching from the housing (201), thereby contributing to improving the usage performance of the first connector (200). For example, C further satisfies 12° ≤ C ≤ 30°, further reducing the interaction force between the locking surface (111) and the contact surface (2011), and further improving the alignment stability between the contact (100) and the housing (201).

[0045] According to some optional embodiments of the present application, the locking part (11) is formed by blanking a sheet metal. The sheet metal is pre-elongated and plastically stretched, and then the locking part (11) is formed to form a straight section. According to this arrangement, the operation and production of the locking part (11) are facilitated, and the production efficiency of the locking part (11) is improved.

[0046] According to some embodiments of the present application, with reference to FIGS. 2 and 3, a locking portion (11) is provided in a main body (1), and the locking portion (11) has a locking surface (111). The length of the locking surface (111) in a direction perpendicular to the central axis of the main body (1) is H, the length of the locking surface (111) in the direction of the central axis of the main body (1) is W, and the thickness of the locking portion (11) is T. Here, H, W, and T further satisfy: 1 / 3 T ≤ H ≤ 1 / 2 T, and 0.05 mm ≤ W ≤ 0.08 mm. For example, in the examples of FIGS. 2 and 3, the length of the locking surface (111) in the up-down direction is H, and the length of the locking surface (111) in the left-right direction is W.

[0047] For example, when the length (H) of the locking surface (111) in a direction perpendicular to the central axis of the main body (1) is less than 1 / 3 T, the length (H) of the locking surface (111) in a direction perpendicular to the central axis of the main body (1) is relatively small, the area of ​​the locking surface (111) is reduced, the contact area between the locking surface (111) and the contact surface (2011) is reduced, and the difficulty of processing the locking surface (111) is increased. When the length (H) of the locking surface (111) in a direction perpendicular to the central axis of the main body (1) is greater than 1 / 2 T, the length (H) of the locking surface (111) in a direction perpendicular to the central axis of the main body (1) becomes relatively larger, so the interlocking angle (B) between the locking surface (111) and the cross section of the locking part (11) becomes relatively smaller, and the force (F) applied by the other end of the locking part (11) to the housing (201) becomes relatively larger, so the possibility of the other end of the locking part (11) penetrating the housing (201) increases, and the possibility of the main body (1) detaching from the housing (201) increases. When the length (W) of the locking surface (111) in the direction of the central axis of the main body (1) is less than 0.05 mm, the length (W) of the locking surface (111) in the direction of the central axis of the main body (1) is relatively small, and the interlocking angle (B) between the locking surface (111) and the cross section of the locking part (11) is relatively small, and the force (F) applied by the other end of the locking part (11) to the housing (201) is relatively large, so the possibility of the other end of the locking part (11) penetrating the housing (201) increases, and the possibility of the main body (1) detaching from the housing (201) increases. When the length (W) of the locking surface (111) in the direction of the central axis of the main body (1) is greater than 0.08 mm, the difficulty of processing the locking surface (111) increases.

[0048] Accordingly, the length (H) of the locking surface (111) in the direction perpendicular to the central axis of the main body (1) and the thickness (T) of the locking part (11) are configured to satisfy 1 / 3 T ≤ H ≤ 1 / 2 T, and the length (W) of the locking surface (111) in the direction of the central axis of the main body (1) is configured to satisfy 0.05 mm ≤ W ≤ 0.08 mm, thereby rationally setting the dimensions of the locking surface (111). This reduces the force (F) applied by the other end of the locking part (11) to the housing (201), thereby lowering the possibility that the other end of the locking part (11) will penetrate the housing (201), preventing the main body (1) from detaching from the housing (201), and improving the stability of use of the first connector (200). Additionally, this facilitates the manufacturing and processing of the locking surface (111), thereby improving the processing efficiency of the contact (100).

[0049] According to some embodiments of the present application, with reference to FIGS. 2 and 3, a locking portion (11) is provided in the main body (1), and the locking portion (11) has a locking surface (111), and the locking surface (111) is smoothly transitioned to one side surface of the locking portion (11) away from the central axis of the main body (1) through a connecting surface (112). For example, in the examples of FIGS. 2 and 3, the outer surface of the connecting surface (112) is approximately arc-shaped. While the contact (100) is inserted into the housing (201), the locking portion (11) is in a pressurized state. When the contact (100) moves to the free end of the locking portion (11) and is separated from one side of the housing (201) facing the main body (1), the right end of the locking portion (11) may be tilted upward. The setting of the connecting surface (112) helps with the sliding and upward tilting of the right end of the locking part (11), thereby improving the assembly speed of the locking part (11) and the housing (201) and further improving the assembly efficiency of the first connector (200). Additionally, during the assembly process of the contact (100) and the housing (201), the connecting surface (112) prevents the worker from being scratched and injured, thereby improving the safety of use of the contact (100).

[0050] According to some embodiments of the present application, with reference to FIG. 4, the thickness of the locking portion (11) is T, and the length of the connecting surface (112) in the direction of the central axis of the main body (1) is S. Here, S and T satisfy: S ≥ 1 / 2 T.

[0051] For example, in the example of FIG. 4, the length of the connecting surface (112) in the left-right direction is S. When the length (S) of the connecting surface (112) in the direction of the central axis of the main body (1) is less than half the thickness (T) of the locking part (11), the length (S) of the connecting surface (112) in the direction of the central axis of the main body (1) is relatively small. As a result, during the assembly process of the housing (201) and the contact (100), the smoothness of the right end of the locking part (11) sliding and tilting upward is reduced, and the assembly time of the housing (201) and the contact (100) increases. Additionally, the connection point between the connecting surface (112) and one side of the locking part (11) away from the center of the main body (1) is relatively sharp, or the connection point between the connecting surface (112) and the locking surface (111) is relatively sharp. As a result, during the assembly process of the contact (100) and the housing (201), the right end of the locking part (11) is prone to scratching and injuring the worker, thereby reducing the safety of use of the contact (100). Therefore, by configuring the thickness (T) of the locking part (11) and the length (S) of the connecting surface (112) in the direction of the central axis of the main body (1) to satisfy S ≥ 1 / 2 T, the length of the connecting surface (112) in the direction of the central axis of the main body (1) is increased. As a result, during the assembly process of the housing (201) and the contact (100), the smoothness of the right end of the locking part (11) sliding upward and tilting is improved, thereby increasing the assembly speed of the housing (201) and the contact (100). Additionally, the connection point between the connecting surface (112) and one side of the locking part (11) away from the center of the main body (1) is relatively smooth, and the connection point between the connecting surface (112) and the locking surface (111) is relatively smooth. As a result, during the assembly process of the contact (100) and the housing (201), the right end of the locking part (11) prevents the worker from being scratched and injured, thereby improving the safety of use of the contact (100).

[0052] According to some embodiments of the present application, with reference to FIG. 1, a locking portion (11) is provided in the main body (1). The locking portion (11) has a locking surface (111). An opening (12) is formed on the outer surface of the main body (1). The side walls of the opening (12) include a first side wall (121) and a second side wall (122) that are opposite each other. One end of the locking portion (11) is connected to the first side wall (121). A position limiting projection (1221) is provided on the second side wall (122). The position limiting projection (1221) is located on one side of the outer surface of the main body (1) adjacent to the center of the main body (1). The other end of the locking portion (11) is adapted to come into contact with the position limiting projection (1221).

[0053] For example, in the example of FIG. 1, the first side wall (121) is the left wall of the opening (12), the second side wall (122) is the right wall of the opening (12), the left end of the locking part (11) is connected to the first side wall (121), and the right end of the locking part (11) is positioned on the position limiting projection (1221). When a part of the main body (1) is inserted into the housing (201), the locking part (11) is pressed downward by the side wall of the housing (201) facing the main body (1), and the right end of the pressed locking part (11) comes into contact with the position limiting projection (1221). Accordingly, during the installation process of the contact (100) and the housing (201), the position limiting projection (1221) limits the right end of the locking part (11), thereby limiting the downward movement of the locking part (11) and preventing the right end of the locking part (11) from being unable to move upward to return to its original position due to excessive yielding of the right end of the locking part (11). This also effectively improves cooperative engagement between the locking part (11) and the housing (201).

[0054] According to some embodiments of the present application, with reference to FIG. 4, the thickness of the locking portion (11) is T, and the difference in distance between one side surface of the position limiting projection (1221) away from the central axis of the main body (1) and the outer surface of the main body (1) is G. Here, G satisfies: 1 / 3 T ≤ G ≤ 1 / 2 T. For example, when the difference in distance (G) between one side surface of the position limiting projection (1221) away from the central axis of the main body (1) and the outer surface of the main body (1) is less than 1 / 3 of the thickness (T) of the locking portion (11), the difference in distance between one side surface of the position limiting projection (1221) away from the central axis of the main body (1) and the outer surface of the main body (1) is relatively small. As a result, the downward movement distance of the right end of the locking portion (11) is shortened. When the right end of the locking part (11) comes into contact with the position limiting projection (1221), the right end of the locking part (11) is likely to come into contact with the housing (201), which hinders the assembly of the contact (100) into the housing (201) and increases the difficulty of assembling the contact (100) and the housing (201). When the difference in distance (G) between one side surface of the position limiting projection (1221) away from the central axis of the main body (1) and the outer surface of the main body (1) is greater than 1 / 2 of the thickness (T) of the locking part (11), the difference in distance between one side surface of the position limiting projection (1221) away from the central axis of the main body (1) and the outer surface of the main body (1) is relatively large. As a result, the downward movement distance of the right end of the locking part (11) increases, and the degree of deformation of the locking part (11) increases. Therefore, the likelihood of the right end of the locking part (11) returning to its original position is reduced, resulting in a decrease in the height of the locking part (11).

[0055] Accordingly, by configuring the thickness (T) of the locking part (11) and the distance (G) between one side surface of the position limiting projection (1221) moving away from the central axis of the main body (1) and the outer surface of the main body (1) to satisfy 1 / 3 T ≤ G ≤ 1 / 2 T, and through the appropriate setting of the position limiting projection (1221), when the right end of the locking part (11) comes into contact with the position limiting projection (1221), the difficulty of assembly of the contact (100) and the housing (201) is reduced, and the assembly efficiency of the first connector (200) is improved. Additionally, the downward movement distance of the right end of the locking part (11) is shortened, thereby reducing the degree of deformation of the locking part (11) and making it easier to return to the original position of the right end of the locking part (11), thereby increasing the height of the locking part (11) in the locked state.

[0056] The conventional contact structure does not include the position limiting projection (1221) of this solution, and the free end of the locking part does not have an angled locking surface (111). In the conventional contact structure, the sheet metal is first blanked, the corresponding positions of the locking part and the housing are cut open, then the locking part is stamped and bent to reach the required height, and finally the locking part is hooked to the inner wall surface of the housing. The aforementioned technical solution is compared with the solution of the present application. The results are shown in the table below (see FIG. 1):

[0057]

[0058] According to the data in the table, it can be concluded that providing a position limiting projection (1221) on the body (1) of the contact (100) can effectively reduce the yield amount of the locking part (11). Thus, after the contact (100) is inserted into the housing (201), the free end of the locking part (11) can be compressed downward and then elastically restored, which helps with the engagement between the locking surface (111) of the locking part (11) and the contact surface (2011) of the housing (201).

[0059] Optionally, with reference to FIG. 1, an elastic contact plate (15) is provided on the main body (1). One end of the elastic contact plate (15) is connected to the main body (1), and the other end of the elastic contact plate (15) extends obliquely toward the central axis of the main body (1) (left-right direction in FIG. 1). According to this arrangement, during the assembly process of the first connector (200) and the second connector (301), it can be ensured that the second connector (301) contacts the elastic contact plate (15), while at the same time, the insertion of the second connector (301) into the first connector (200) is facilitated. Additionally, the second connector (301) can also be smoothly withdrawn from the first connector (200), thereby facilitating the assembly and disassembly of the first connector (200) and the second connector (301).

[0060] Optionally, with reference to FIG. 1, a crimping member (16) is formed on the main body (1). The crimping member (16) includes a conductor wire clamp (161) and an insulating wire clamp (162) that are connected to each other. The conductor wire clamp (161) is connected between the center of the main body (1) and the insulating wire clamp (162), and the conductor wire clamp (161) and the insulating wire clamp (162) are arranged sequentially from left to right. When the contact (100) is used with the first connector (200), the two free ends of the insulating wire clamp (162) come into contact with each other to secure the wires. The insulating sheaths of the plurality of wires come into contact with the inner wall surface of the conductor wire clamp (161), and the plurality of wires are wrapped by the insulating wire clamp (162). Additionally, the conductors of the plurality of wires come into contact with the conductor wire clamp (161). Two free ends of the conductor wire clamp (161) are brought close to each other, so that the outer surface of the conductor wire clamp (161) forms a roughly circular shape, and a plurality of wires are wrapped inside the conductor wire clamp (161). Thus, this helps in the connection between the crimping member (16) and the wires, thereby facilitating the use of the contact (100). Additionally, it helps in the secure connection between the crimping member (16) and the wires while the wires are normally energized, and the safety of the use of the contact (100) is improved by providing an insulating wire clamp (162).

[0061] Additionally, with reference to FIG. 6, the main body (1) is formed by folding a sheet-like structure, and the main body (1) includes a first side section (17), a second side section (18), and two third side sections (19). The first side section (17) is the upper side section of the main body (1). An opening (12) is formed in the first side section (17) and penetrates the upper and lower sides of the first side section (17) in the vertical direction. The second side section (18) is the bottom side section of the main body (1). The third side section (19) is located between the first side section (17) and the second side section (18). The main body (1) is approximately cylindrical. Therefore, the main body (1) has a simple structure, making it easy to form, and accordingly, the production efficiency of the main body (1) is improved.

[0062] Refer to FIG. 1 for a first connector (200) according to one embodiment of the second aspect of the present application. The first connector (200) includes a contact (100) for the first connector (200) according to one embodiment of the first aspect of the present application.

[0063] According to the first connector (200) of the present application, by using the aforementioned contact (100), the stability of use of the first connector (200) is improved and the lifespan of the first connector (200) is extended.

[0064] According to some embodiments of the present application, with reference to FIG. 1, the first connector (200) further includes a housing (201).

[0065] Specifically, the mating channel (2012) is defined inside the housing (201). At least a portion of the body (1) of the first connector (200) is inserted from one end of the housing (201) and mated within the mating channel (2012). A receiving slot (2013) is formed on the inner wall of the mating channel (2012). The inner wall surface of the receiving slot (2013) adjacent to one end of the housing (201) has a contact surface (2011). The locking surface (111) of the locking portion (11) of the first connector (200) is adapted to come into contact with the contact surface (2011) to restrict movement of the body (1) toward one end of the housing (201).

[0066] For example, in the example of FIG. 1, the matching channel (2012) extends through the housing (201) along the axial direction of the housing (201). The left side of the main body (1) is inserted from the right end of the housing (201) and is matched within the matching channel (2012). The upper side wall of the matching channel (2012) is recessed upward to form a receiving slot (2013). The receiving slot (2013) is opposite to the locking portion (11). The contact surface (2011) is located on the right wall of the receiving slot (2013). The locking surface (111) is adapted to be in contact with the contact surface (2011) to restrict movement to the right of the main body (1). This arrangement facilitates the assembly of the housing (201) and the contact (100), thereby improving the assembly efficiency of the first connector (200). Additionally, this prevents the main body (1) from detaching from the housing (201), thereby improving the assembly stability of the contact (100) and the housing (201) and further improving the usage stability of the first connector (200). Additionally, the housing (201) has a simple structure, which reduces the difficulty of producing the housing (201) and lowers the production cost of the housing (201).

[0067] Refer to FIG. 7 for a connector assembly (300) according to one embodiment of the third aspect of the present application. The connector assembly (300) includes a first connector (200) according to one embodiment of the second aspect of the present application.

[0068] According to the connector assembly (300) of the present application, by using the first connector (200) described above, the performance of the connector assembly (300) is improved and the lifespan of the connector assembly (300) is extended.

[0069] According to some embodiments of the present application, with reference to FIG. 7, the connector assembly (300) further comprises a second connector (301). The second connector (301) is inserted from the other end of the housing (201) of the first connector (200) and fitted within the body (1) of the contact (100) of the first connector (200). For example, in the example of FIG. 7, the second connector (301) is inserted from the left end of the housing (201) and fitted within the body (1) of the contact (100). The second connector (301) contacts the elastic contact plate (15) of the body (1) to form a conductive circuit between the first connector (200) and the second connector (301). This improves the stability of the electrical connection between the first connector (200) and the second connector (301), thereby improving the stability of use of the connector assembly (300).
