DETAILED DESCRIPTION
[0044] The embodiments of the present application are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The contact 100 for the first connector 200 according to the embodiment of the first aspect of the present application is described below with reference to Figures 1 to 6.
[0045] As shown in FIG. 1 and FIG. 4 , the contact 100 for the first connector 200 according to the embodiment of the first aspect of the present application includes a main body 1 .
[0046] Specifically, the main body 1 includes a locking surface 111, which is configured to be non-opposed to the shear position (e.g., the dashed position indicated by arrow A in FIG1 ) of the housing 201 of the first connector 200 when locked. For example, in the examples of FIG1 and FIG4 , the locking surface 111 is located at the right end of the upper portion of the main body 1. When the contact 100 is engaged with the housing 201, the locking surface 111 cooperates with the inner wall of the housing 201 to lock the contact 100 with the housing 201. When the contact 100 and the housing 201 are assembled, the main body 1 of the contact 100 extends into the housing 201. After the locking surface 111 and the housing 201 are locked, a rightward pulling force (i.e., opposite to the direction of insertion) is applied to the main body 1, creating a pair of action and reaction forces between the locking surface 111 and the inner wall of the housing 201 to detect whether the contact 100 is locked in place. By configuring the locking surface 111 to be non-opposed to the shear position of the housing 201 of the first connector 200 when locked, that is, the locking surface 111 is not left-to-right opposed to the aforementioned shear position, the force exerted by the locking surface 111 on the inner wall of the housing 201 is reduced ("force" refers to the shear force exerted by the locking surface 111 on the inner wall of the housing 201), making it difficult for the locking surface 111 to puncture the housing 201, thereby effectively preventing the main body 1 of the contact 100 from falling out of the housing 201 after the housing 201 is punctured, improving the assembly stability of the contact 100 and the housing 201, and thus improving the operational stability of the first connector 200. Furthermore, this facilitates the long-term normal use of the housing 201 of the first connector 200, thereby extending the service life of the first connector 200.
[0047] For example, in the example of the present application, as shown in FIG1 , when the locking surface 111 applies a force to the inner wall of the housing 201, the shear position is the position where the housing 201 is easily broken, that is, the dotted line position indicated by arrow A in FIG1 . The dotted line position is located above the contact surface between the locking surface 111 and the inner wall of the housing 201, thereby reducing the force applied by the locking surface 111 to the inner wall of the housing 201. When the easily broken position of the housing 201 is opposite to the locking surface 111 in the left-right direction, the housing 201 is more likely to break at the breaking position under the force applied by the locking surface 111, that is, the main body 1 is more likely to fall out of the housing 201.
[0048] According to the contact 100 for the first connector 200 of the present application, by configuring the locking surface 111 to be non-opposed to the shear position of the housing 201 of the first connector 200 when locked, the force exerted by the locking surface 111 on the inner wall of the housing 201 is reduced, and the locking surface 111 is less likely to puncture the housing 201, thereby preventing the main body 1 of the contact 100 from falling out of the housing 201, improving the assembly stability of the contact 100 and the housing 201, and thereby improving the operational stability of the first connector 200. Furthermore, the service life of the first connector 200 is also extended.
[0049] According to some embodiments of the present application, referring to Figures 1 and 4 , the shearing position is located on a side of the locking surface 111 away from the center of the main body 1. For example, in the examples of Figures 1 and 4 , the shearing position is located above the locking surface 111. With this arrangement, when the locking surface 111 applies force to the housing 201, the housing 201 is less likely to break at the shearing position, the housing 201 is less likely to be damaged, and the main body 1 is less likely to fall off the housing 201, thereby extending the service life of the housing 201 and further improving the operational stability of the first connector 200.
[0050] According to some embodiments of the present application, with reference to FIG1 , the housing 201 has a stop surface 2011. When the locking surface 111 is locked with the housing 201, the locking surface 111 abuts against the stop surface 2011, and the locking surface 111 and the stop surface 2011 are parallel. For example, in the example of FIG1 , the locking surface 111 and the stop surface 2011 are opposite to each other along the axial direction of the main body (i.e., the left-right direction in FIG1 ). When the main body 1 is subjected to a force pulling to the right, the main body 1 moves to the right until the locking surface 111 abuts against the stop surface 2011 (as shown in FIG2 ). Thus, the stop surface 2011 limits the locking surface 111, restricting the main body 1 from further moving to the right and preventing the main body 1 from falling off the housing 201. Furthermore, by arranging the locking surface 111 to be parallel to the abutting surface 2011, the force exerted by the locking surface 111 on the abutting surface 2011 can be effectively reduced, thereby reducing the shear force exerted by the locking surface 111 on the housing 201, thereby preventing the locking surface 111 from piercing the inner wall of the housing 201 and then falling off the housing 201. In addition, the shearing positions of the locking surface 111 and the housing 201 when locked are effectively ensured to be non-opposite, thereby further preventing the main body 1 from falling off the housing 201.
[0051] According to some embodiments of the present application, with reference to FIG4 , a locking portion 11 is provided on the main body 1, and 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, and the locking surface 111 is located at the other end of the locking portion 11. For example, in the example of FIG4 , the left end of the locking portion 11 is connected to the main body 1, and the right end of the locking portion 11 extends obliquely upward, and the locking surface 111 is located at the right end surface of the locking portion 11. With such an arrangement, the locking portion 11 can tilt upward, thereby facilitating the locking engagement of the locking portion 11 with the housing 201, thereby improving the performance of the main body 1. In addition, the locking portion 11 has a simple structure and is easy to produce, thereby reducing the production cost of the locking portion 11. It should be noted that the length of the locking surface 111 in the direction perpendicular to the central axis of the main body 1 (that is, the up and down direction of Figure 4) and the length of the locking surface 111 in the direction of the central axis of the main body 1 can be determined according to the gap between the upper blade 13 and the lower blade 14 of the stamping die and the sharpness of the blade (as shown in Figure 5), which is conducive to controlling the formation of the locking surface 111.
[0052] 2 and 3 , the inclination angle of the locking portion 11 is C, the angle between the locking surface 111 and the cross section of the locking portion 11 (that is, the angle between the locking surface 111 and the plane in which the thickness direction of the locking portion 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 exerted by the other end of the locking portion 11 on the shell 201 is F ("force F" refers to the shear force of the end of the locking portion 11 on the stop surface 2011 of the shell 201), wherein C, B, H, W and F respectively satisfy: B = arctan(W / H), F∝1 / Sin(B+C).
[0053] For example, the angle B between the locking surface 111 and the cross-section of the locking portion 11 is proportional to the ratio 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 (i.e., W / H). That is, the ratio 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 (i.e., W / H) is smaller, and correspondingly, the angle B between the locking surface 111 and the cross-section of the locking portion 11 is smaller, so that it is convenient to adjust the size of the angle B between the locking surface 111 and the cross-section of the locking portion 11 by the length H of the locking surface 111 in the 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.
[0054] For example, the force F exerted by the other end of the locking portion 11 on the housing 201 is inversely proportional to Sin(B+C). The force F exerted by the other end of the locking portion 11 on the housing 201 is inversely proportional to the angle B between the locking surface 111 and the cross section of the locking portion 11, or the inclination angle C of the locking portion 11. That is, when the inclination angle C of the locking portion 11 remains unchanged, the greater the angle B between the locking surface 111 and the cross section of the locking portion 11, the smaller the force F exerted by the other end of the locking portion 11 on the housing 201. When the angle B between the locking surface 111 and the cross section of the locking portion 11 remains unchanged, the larger the inclination angle C of the locking portion 11, the smaller the force F exerted by the other end of the locking portion 11 on the shell 201. Therefore, it is easy to reduce the force F exerted by the other end of the locking portion 11 on the shell 201 by changing the angle B between the locking surface 111 and the cross section of the locking portion 11 or the inclination angle C of the locking portion 11, thereby avoiding puncturing the shell 201 due to the large force F, and further preventing the main body 1 of the contact 100 from falling off from the shell 201.
[0055] Through actual verification, the actual results are consistent with the theory, and the results are shown in the following table. It can be seen from the data in the table that the locking portion 11 of the new structure provided with the locking surface 111 has a greater holding force on the shell 201, that is, the structure in this solution can withstand a greater pulling force and the main body 1 is not easy to fall out of the shell 201. In addition, by providing the following limiting protrusion 1221, after the main body 1 of this solution is inserted into the shell 201, the locking portion 11 can maintain a higher height, which can effectively solve the problem that the locking portion 11 is pressed down and does not rebound during the process of inserting the main body 1 into the shell 201. It should be noted that "the holding force of the locking portion on the shell" refers to the external force value that the main body 1 can withstand when it is pulled by an external force. The old structure refers to a structure without the locking surface 111 of this application.
[0056] Optionally, referring to FIG3 , the angle B between the locking surface 111 and the cross section of the locking portion 11 is 30°≤B≤60°. For example, when the angle B between the locking surface 111 and the cross section of the locking portion 11 is less than 30°, the angle B between the locking surface 111 and the cross section of the locking portion 11 is small, resulting in a large force F exerted by the other end of the locking portion 11 on the housing 201. This makes it easier for the locking portion 11 to pierce the housing 201, and the main body 1 of the contact 100 to fall off from the housing 201, thereby reducing the stability of the first connector 200. When the angle B between the locking surface 111 and the cross section of the locking portion 11 is greater than 60°, the angle B between the locking surface 111 and the cross section of the locking portion 11 is large, and the locking surface 111 tends to be flush with the side of the locking portion 11 closer to the center of the main body 1 (i.e., the axial direction of the main body 1), thereby increasing the force of the locking portion 11 on the stop surface 2011, and easily damaging the inner wall surface of the housing 201 when the main body 1 is pulled to the right. Therefore, by setting the angle B between the locking surface 111 and the cross section of the locking portion 11 to meet 30°≤B≤60°, the angle B between the locking surface 111 and the cross section of the locking portion 11 is reasonably set, and the force F exerted by the other end of the locking portion 11 on the housing 201 is small, thereby making it difficult for the locking portion 11 to puncture the housing 201, preventing the main body 1 of the contact 100 from easily falling off the housing 201, thereby helping to improve the performance of the first connector 200. For example, C further satisfies: 12°≤C≤30°, so as to further reduce the interaction force between the locking surface 111 and the abutting surface 2011 , and further improve the matching stability between the contact 100 and the housing 201 .
[0057] According to some optional embodiments of the present application, the locking portion 11 is formed by blanking a plate, the plate is pre-stretched and plastically elongated, and then the locking portion 11 is shaped to form a straight section. This arrangement facilitates the operation and production of the locking portion 11, thereby improving the production efficiency of the locking portion 11.
[0058] According to some embodiments of the present application, with reference to Figures 2 and 3, a locking portion 11 is provided on the main body 1. 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. Wherein H, W, and T further satisfy: 1 / 3T≤H≤1 / 2T, 0.05mm≤W≤0.08mm. For example, in the examples of Figures 2 and 3, the length of the locking surface 111 in the vertical direction is H, and the length of the locking surface 111 in the horizontal direction is W.
[0059] For example, when the length H of the locking surface 111 in the direction perpendicular to the central axis of the main body 1 is less than 1 / 3T, the length H of the locking surface 111 in the direction perpendicular to the central axis of the main body 1 is relatively small, which reduces the area of the locking surface 111, reduces the contact area between the locking surface 111 and the abutment surface 2011, and increases the difficulty of machining the locking surface 11. When the length H of the locking surface 111 in the direction perpendicular to the central axis of the main body 1 is greater than 1 / 2T, the length H of the locking surface 111 in the direction perpendicular to the central axis of the main body 1 is relatively large, thereby reducing the angle B between the locking surface 111 and the cross section of the locking portion 11, and increasing the force F exerted by the other end of the locking portion 11 on the housing 201. This makes it easier for the other end of the locking portion 11 to pierce the housing 201, and the main body 1 is easily detached from the housing 201. 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 small, resulting in a smaller angle B between the locking surface 111 and the cross section of the locking portion 11. This results in a larger force F exerted by the other end of the locking portion 11 on the housing 201, making it easier for the other end of the locking portion 11 to pierce the housing 201, and the main body 1 to fall out of the housing 201. 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 machining difficulty of the locking surface 111 increases.
[0060] Therefore, by setting 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 portion 11 to satisfy 1 / 3T≤H≤1 / 2T, and the length W of the locking surface 111 in the direction of the central axis of the main body 1 to satisfy 0.05mm≤W≤0.08mm, the size of the locking surface 111 is reasonably set, reducing the force F exerted by the other end of the locking portion 11 on the housing 201, thereby making it difficult for the other end of the locking portion 11 to puncture the housing 201, preventing the main body 1 from falling off the housing 201, and improving the operational stability of the first connector 200. In addition, it is also beneficial to the production and processing of the locking surface 111, improving the processing efficiency of the contact 100.
[0061] According to some embodiments of the present application, referring to Figures 2 and 3 , a locking portion 11 is provided on the main body 1 . The locking portion 11 has a locking surface 111 . A connecting surface 112 smoothly transitions between the locking surface 111 and a surface of the locking portion 11 on a side away from the central axis of the main body 1 . For example, in the examples of Figures 2 and 3 , the outer circumference of the connecting surface 112 is generally arc-shaped. During the insertion of the contact 100 into the housing 201 , the locking portion 11 is in a pressed state. When the contact 100 moves to the free end of the locking portion 11 and separates from the side of the housing 201 facing the main body 1 , the right end of the locking portion 11 can tilt upward. The provision of the connecting surface 112 facilitates the sliding and upward tilting of the right end of the locking portion 11, thereby increasing the assembly speed of the locking portion 11 and the housing 201, thereby improving the assembly efficiency of the first connector 200 . Furthermore, during the assembly of the contact 100 and the housing 201 , the connecting surface 112 can prevent workers from scratching, thereby improving the safety of the contact 100 .
[0062] According to some embodiments of the present application, referring 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, wherein S and T satisfy: S≥1 / 2T.
[0063] For example, in the example of FIG4 , the length of the connecting surface 112 along 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 portion 11, the length S of the connecting surface 112 in the direction of the central axis of the main body 1 is small, thereby reducing the smoothness of the upward sliding and tilting of the right end of the locking portion 11 during the assembly of the housing 201 and the contact 100, thereby prolonging the assembly time of the housing 201 and the contact 100. In addition, the connection between the connecting surface 112 and the locking portion 11 away from the center of the main body 1 is relatively sharp, or the connection between the connecting surface 112 and the locking surface 111 is relatively sharp. As a result, during the assembly of the contact 100 and the housing 201, the right end of the locking portion 11 is easily scratched by the staff, thereby reducing the safety of the contact 100. Thus, by setting the thickness T of the locking portion 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 / 2T, the length of the connecting surface 112 in the direction of the central axis of the main body 1 is increased, thereby improving the smoothness of the upward sliding and tilting of the right end of the locking portion 11 during the assembly process of the housing 201 and the contact 100, thereby improving the assembly speed of the housing 201 and the contact 100. In addition, the connection between the connecting surface 112 and the side of the locking portion 11 away from the center of the main body 1 is relatively smooth, and the connection between the connecting surface 112 and the locking surface 111 is relatively smooth, thereby preventing the right end of the locking portion 11 from scratching personnel during the assembly process of the contact 100 and the housing 201, thereby improving the safety of the contact 100.
[0064] According to some embodiments of the present application, referring to Figure 1, a locking portion 11 is provided on the main body 1, and the locking portion 11 has a locking surface 111. An opening 12 is formed on the outer peripheral surface of the main body 1, and the side walls of the opening 12 include a first side wall 121 and a second side wall 122 opposite to each other. One end of the locking portion 11 is connected to the first side wall 121, and a limiting protrusion 1221 is provided on the second side wall 122. The limiting protrusion 1221 is located on the side of the outer peripheral surface of the main body 1 adjacent to the center of the main body 1, and the above-mentioned other end of the locking portion 11 is suitable for stopping with the limiting protrusion 1221.
[0065] For example, in the example of FIG1 , the first sidewall 121 is the left sidewall of the opening 12, and the second sidewall 122 is the right sidewall of the opening 12. The left end of the locking portion 11 is connected to the first sidewall 121, and the right end of the locking portion 11 is located above the limiting protrusion 1221. When a portion of the main body 1 is inserted into the housing 201, the locking portion 11 is pressed downward by the sidewall of the housing 201 facing the main body 1. The pressed right end of the locking portion 11 abuts against the limiting protrusion 1221. Thus, during the installation of the contact 100 and the housing 201, the limiting protrusion 1221 limits the right end of the locking portion 11, restricting downward movement of the locking portion 11 and preventing the right end of the locking portion 11 from excessively yielding and being unable to move upward to return to its original position. This effectively improves the cooperation between the locking portion 11 and the housing 201.
[0066] According to some embodiments of the present application, referring to FIG4 , the thickness of the locking portion 11 is T, and the distance difference between the side surface of the limiting protrusion 1221 away from the central axis of the main body 1 and the outer peripheral surface of the main body 1 is G, where G satisfies the following: 1 / 3T≤G≤1 / 2T. For example, when the distance difference G between the side surface of the limiting protrusion 1221 away from the central axis of the main body 1 and the outer peripheral surface of the main body 1 is less than 1 / 3 of the thickness T of the locking portion 11, the distance difference between the side surface of the limiting protrusion 1221 away from the central axis of the main body 1 and the outer peripheral surface of the main body 1 is small, thereby shortening the downward movement distance of the right end of the locking portion 11. When the right end of the locking portion 11 abuts the limiting protrusion 1221, the right end of the locking portion 11 is easily contacted with the housing 201, thereby hindering the assembly of the contact 100 into the housing 201 and increasing the difficulty of assembling the contact 100 with the housing 201. When the distance difference G between the side surface of the limiting protrusion 1221 away from the central axis of the main body 1 and the outer peripheral surface of the main body 1 is greater than 1 / 2 of the thickness T of the locking portion 11, the distance difference between the side surface of the limiting protrusion 1221 away from the central axis of the main body 1 and the outer peripheral surface of the main body 1 is large, thereby increasing the downward movement distance of the right end of the locking portion 11, increasing the deformation degree of the locking portion 11, and making it difficult for the right end of the locking portion 11 to return to its original position, thereby reducing the height of the locking portion 11.
[0067] Thus, by ensuring that the thickness T of the locking portion 11 and the distance difference G between the side surface of the limiting protrusion 1221 away from the central axis of the main body 1 and the outer peripheral surface of the main body 1 meet 1 / 3T≤G≤1 / 2T, the positioning of the limiting protrusion 1221 is reasonable. This reduces the difficulty of assembling the contact 100 and the housing 201 when the right end of the locking portion 11 abuts the limiting protrusion 1221, thereby improving the assembly efficiency of the first connector 200. Furthermore, the downward movement distance of the right end of the locking portion 11 is shortened, thereby reducing the degree of deformation of the locking portion 11, making it easier to restore the right end of the locking portion 11 to its original position, and increasing the height of the locking portion 11 when in the locked state.
[0068] The traditional contact structure does not include the limiting protrusion 1221 of this solution, and the free end of its locking portion does not have the angled locking surface 111. The traditional contact structure is to pre-punch the plate, cut the corresponding positions of the locking portion and the shell, then stamp and bend the locking portion to the corresponding height, and then hang the locking portion on the inner wall of the shell. The above technical solution is actually compared with the solution of this application, and the results are shown in the following table (refer to Figure 1):
[0069] According to the data in the table, it can be concluded that providing a limiting protrusion 1221 on the main body 1 of the contact 100 can effectively reduce the yield of the locking portion 11, so that after the contact 100 is inserted into the shell 201, the free end of the locking portion 11 can rebound after being squeezed down, which is conducive to the hooking of the locking surface 111 of the locking portion 11 with the stop surface 2011 of the shell 201.
[0070] Optionally, referring to FIG1 , the main body 1 is provided with an elastic contact piece 15. One end of the elastic contact piece 15 is connected to the main body 1, and the other end of the elastic contact piece 15 extends obliquely toward the central axis of the main body 1 (the left-right direction as shown in FIG1 ). With this arrangement, during assembly of the first connector 200 and the second connector 301, the second connector 301 can be inserted into the first connector 200 while ensuring contact between the second connector 301 and the elastic contact piece 15. At the same time, the second connector 301 can also be smoothly removed from the first connector 200, thereby facilitating assembly and disassembly of the first connector 200 and the second connector 301.
[0071] Optionally, referring to FIG1 , a crimping member 16 is formed on the main body 1. The crimping member 16 includes a conductor clamp 161 and an insulating clamp 162 connected to each other. The conductor clamp 161 is connected between the center of the main body 1 and the insulating clamp 162, with the conductor clamp 161 and the insulating clamp 162 being arranged from left to right. When the contact 100 is used in the first connector 200, the two free ends of the insulating clamp 162 approach each other to secure the wires. The insulating outer shells of multiple wires contact the inner wall surface of the conductor clamp 161, and the multiple wires are wrapped by the insulating clamp 162. At the same time, the conductors of the multiple wires contact the conductor clamp 161. The two free ends of the conductor clamp 161 approach each other so that the outer circumference of the conductor clamp 161 is roughly annular, and the multiple wires are wrapped within the conductor clamp 161. This facilitates the connection between the crimping member 16 and the wires, thereby facilitating the use of the contact 100. In addition, it is beneficial to ensure a relatively tight connection between the crimping piece 16 and the wire while the wire conducts electricity normally, and the provision of the insulating wire clamp 162 improves the safety of the contact 100 in use.
[0072] Further, referring to Figure 6 , the main body 1 is formed by wrapping a sheet-like structure and includes a first side portion 17, a second side portion 18, and two third side portions 19. The first side portion 17 is the top side portion of the main body 1, and the opening 12 is formed on the first side portion 17 and extends vertically through the upper and lower sides of the first side portion 17. The second side portion 18 is the bottom side portion of the main body 1, and the third side portion 19 is located between the first side portion 17 and the second side portion 18. The main body 1 is generally cylindrical. As a result, the main body 1 has a simple structure and is easy to form, thereby improving the production efficiency of the main body 1.
[0073] According to the second embodiment of the present application, the first connector 200 , referring to FIG. 1 , includes the contact 100 for the first connector 200 according to the first embodiment of the present application.
[0074] According to the first connector 200 of the present application, by adopting the above-mentioned contacts 100 , the use stability of the first connector 200 is improved and the service life of the first connector 200 is extended.
[0075] According to some embodiments of the present application, referring to FIG. 1 , the first connector 200 further includes a housing 201 .
[0076] Specifically, a mating channel 2012 is defined in the shell 201, and at least a portion of the main body 1 of the first connector 200 extends from one end of the shell 201 to be mated in the mating channel 2012. A receiving groove 2013 is formed on the inner wall of the mating channel 2012, and the inner wall surface of the receiving groove 2013 adjacent to one end of the shell 201 has a stop surface 2011. The locking surface 111 of the locking portion 11 of the first connector 200 is suitable for abutting against the stop surface 2011 to limit the movement of the main body 1 toward one end of the shell 201.
[0077] For example, in the example of FIG1 , a mating channel 2012 extends axially through the housing 201. The left side portion of the main body 1 extends from the right end of the housing 201 and fits within the mating channel 2012. The upper sidewall of the mating channel 2012 is recessed upward to form a receiving groove 2013. The receiving groove 2013 is opposite the locking portion 11. The abutment surface 2011 is located on the right wall of the receiving groove 2013. The locking surface 111 is adapted to abut against the abutment surface 2011 to limit rightward movement of the main body 1. This arrangement facilitates assembly of the housing 201 and the contact 100, thereby improving the assembly efficiency of the first connector 200. Furthermore, it prevents the main body 1 from falling off the housing 201, thereby improving the assembly stability of the contact 100 and the housing 201, and thereby improving the operational stability of the first connector 200. Furthermore, the simple structure of the housing 201 reduces the difficulty in producing the housing 201, thereby reducing the production cost of the housing 201.
[0078] According to the third aspect of the present application, the connector assembly 300 , referring to FIG. 7 , includes the first connector 200 according to the second aspect of the present application.
[0079] According to the connector assembly 300 of the present application, by adopting the above-mentioned first connector 200, the performance of the connector assembly 300 is improved and the service life of the connector assembly 300 is extended.
[0080] According to some embodiments of the present application, referring to FIG7 , the connector assembly 300 further includes a second connector 301. The second connector 301 extends from the other end of the housing 201 of the first connector 200 and fits within the body 1 of the contact 100 of the first connector 200. For example, in the example of FIG7 , the second connector 301 extends from the left end of the housing 201 and fits within the body 1 of the contact 100. The second connector 301 contacts the elastic contact piece 15 on the body 1, forming a conductive loop 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 the connector assembly 300 in use.
