[0045] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 6 A contact 100 used in a first connector 200 according to an embodiment of a first aspect of the present invention is described.

[0046] like Figure 1 and Figure 4As shown, a contact 100 for a first connector 200 according to an embodiment of the first aspect of the present invention includes a main body 1 .

[0047] Specifically, the main body 1 has a locking surface 111, which is configured to be locked with the housing 201 of the first connector 200 at a shear position (for example, Figure 1 The dashed line position indicated by arrow A in the figure is not relative. Figure 1 and Figure 4 In the example, the locking surface 111 is located at the right end of the upper part of the main body 1. When the contact 100 is fitted on the housing 201, the locking surface 111 cooperates with the inner wall surface of the housing 201 to lock the contact 100 with the housing 201. When the contact 100 is assembled with the housing 201, the main body 1 of the contact 100 extends into the housing 201. After the locking surface 111 is locked with the housing 201, it is necessary to detect whether it is locked in place. When a pulling force is applied to the main body 1 to the right (i.e., opposite to the extension direction of the main body 1), a pair of action and reaction forces are formed between the locking surface 111 and the inner wall surface of the housing 201. By setting the locking surface 111 to be non-opposite to the shear position when the housing 201 of the first connector 200 is locked, that is, the locking surface 111 is not opposite to the above-mentioned shear position, thereby reducing the force of the locking surface 111 on the inner wall of the housing 201 ("force" refers to the shear force of 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 off from the housing 201 after the housing 201 is punctured, improving the assembly stability of the contact 100 and the housing 201, and further improving the use stability of the first connector 200. Moreover, it is conducive to the normal use of the housing 201 of the first connector 200 for a long time, thereby extending the service life of the first connector 200.

[0048] For example, in the example of this application, Figure 1 As shown, when the locking surface 111 applies a force to the inner wall surface of the housing 201, the above-mentioned shear position is the position where the housing 201 is prone to breakage, that is, Figure 1 The dotted line position indicated by the middle arrow A is located above the contact surface between the locking surface 111 and the inner wall surface of the housing 201, so as to reduce the force exerted by the locking surface 111 on the inner wall surface 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 of the locking surface 111, that is, the main body 1 is more likely to fall off from the housing 201.

[0049] According to the contact 100 for the first connector 200 of the present invention, the locking surface 111 is configured to be non-opposite to the shear position when the housing 201 of the first connector 200 is locked, thereby reducing the force of the locking surface 111 on the inner wall surface of the housing 201, and the locking surface 111 is not easy to pierce the housing 201, thereby preventing the main body 1 of the contact 100 from falling off from the housing 201, improving the assembly stability of the contact 100 and the housing 201, and further improving the use stability of the first connector 200. In addition, the service life of the first connector 200 is also extended.

[0050] According to some embodiments of the present invention, referring to Figure 1 and Figure 4 , the shearing position is located on the side of the locking surface 111 away from the center of the main body 1. For example, Figure 1 and Figure 4 In the example, the shearing position is located above the locking surface 111. With such a configuration, when the locking surface 111 applies force to the housing 201, the housing 201 is not easily broken at the shearing position, the housing 201 is not easily damaged, and the main body 1 is not easily detached from the housing 201, thereby extending the service life of the housing 201 and further improving the use stability of the first connector 200.

[0051] According to some embodiments of the present invention, referring to Figure 1 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 is parallel to the stop surface 2011. Figure 1 In the example, the locking surface 111 and the stop surface 2011 are aligned along the axial direction of the main body (ie Figure 1 When the main body 1 is pulled to the right, the main body 1 moves to the right until the locking surface 111 abuts against the abutting surface 2011 (such as Figure 2 As shown in the figure, the stop surface 2011 limits the locking surface 111, restricting the main body 1 from continuing to move to the right, and preventing the main body 1 from falling off the shell 201. Moreover, by setting the locking surface 111 parallel to the stop surface 2011, the force of the locking surface 111 on the stop surface 2011 can be effectively reduced, thereby reducing the shear force of the locking surface 111 on the shell 201, so as to prevent the locking surface 111 from piercing the lower part of the inner wall of the shell 201 and falling off the shell 201. In addition, it is effectively ensured that the shear position of the locking surface 111 and the shell 201 when locked is not relative, thereby further preventing the main body 1 from falling off the shell 201.

[0052] According to some embodiments of the present invention, referring to Figure 4The main body 1 is provided with a locking portion 11, which 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, Figure 4 In the example, 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 upward at an angle, and the locking surface 111 is located at the right end surface of the locking portion 11. With this arrangement, the locking portion 11 can be tilted upward, thereby facilitating the locking cooperation between the locking portion 11 and the shell 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 locking surface 111 is perpendicular to the central axis of the main body 1 (that is, Figure 4 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 (such as Figure 5 As shown), this is beneficial to controlling the formation of the locking surface 111.

[0053] Combination Figure 2 and Figure 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).

[0054] 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 (that is, W / H). That is, the smaller 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 (that is, W / H) is, the smaller the corresponding angle B between the locking surface 111 and the cross section of the locking portion 11 is, 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.

[0055] 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 larger 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 is, the smaller the force F exerted by the other end of the locking portion 11 on the shell 201 is. It is thus 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 cross sections 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 avoiding the main body 1 of the contact 100 from falling off from the shell 201.

[0056] Through actual verification, the actual situation is consistent with the theory, and the results are shown in the following table. From the data in the table, it can be obtained 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 scheme can withstand a greater pulling force and is not easy to fall out of the shell. In addition, by providing the following limiting protrusion 1221, after the main body 1 of this scheme 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 insertion of 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 can be borne when the main body 1 is pulled by an external force. The old structure refers to the one without the locking surface 111 of this application.

[0057]

[0058]

[0059] Optionally, refer to Figure 3, the angle between the locking surface 111 and the cross section of the locking portion 11 is B, where B satisfies: 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, so that the force F exerted by the other end of the locking portion 11 on the housing 201 is large, so that the locking portion 11 is easy to pierce the housing 201, and the body 1 of the contact 100 is easy 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 close to the center of the main body 1 (that is, the axial direction of the main body 1), which increases the force of the locking portion 11 on the stop surface 2011, and the inner wall surface of the shell 201 is easily damaged when the main body 1 is pulled to move 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 setting of the angle B between the locking surface 111 and the cross section of the locking portion 11 is reasonable, and the force F of the other end of the locking portion 11 on the shell 201 is small, so that the locking portion 11 is not easy to pierce the shell 201, and the main body 1 of the contact 100 is prevented from easily falling off from the shell 201, which helps 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 , so as to further improve the matching stability between the contact 100 and the housing 201 .

[0060] According to some optional embodiments of the present invention, the locking portion 11 is formed by blanking a plate, the plate is stretched in advance to plastically elongate, and then a straight section is formed by shaping the locking portion 11. In this way, the locking portion 11 is easy to operate and produce, thereby improving the production efficiency of the locking portion 11.

[0061] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The main body 1 is provided with a locking portion 11, the locking portion 11 has a locking surface 111, 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 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 Figure 2 and Figure 3 In the example of FIG. 1 , 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.

[0062] 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 small, the area of ​​the locking surface 111 is small, the contact area between the locking surface 111 and the abutment surface 2011 is reduced, and the processing difficulty of the locking surface 11 is increased. 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 large, so that the angle B between the locking surface 111 and the cross section of the locking portion 11 is small, the force F exerted by the other end of the locking portion 11 on the housing 201 is large, and the other end of the locking portion 11 is easy to pierce the housing 201, and the main body 1 is easy to fall off 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, so that the angle B between the locking surface 111 and the cross section of the locking portion 11 is small, and the force F exerted by the other end of the locking portion 11 on the housing 201 is large, so that the other end of the locking portion 11 is easy to pierce the housing 201, and the main body 1 is easy to fall off 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 greater than 0.08 mm, the difficulty of processing the locking surface 111 is increased.

[0063] 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, when the length W of the locking surface 111 in the direction of the central axis of the main body 1 satisfies 0.05mm≤W≤0.08mm, the size of the locking surface 111 is reasonably set, reducing the force F of the other end of the locking portion 11 on the housing 201, so that the other end of the locking portion 11 is not easy to pierce the housing 201, avoiding the main body 1 from falling off from the housing 201, and improving the use stability of the first connector 200. In addition, it is also conducive to the production and processing of the locking surface 111, and improves the processing efficiency of the contact 100.

[0064] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The main body 1 is provided with a locking portion 11, and the locking portion 11 has a locking surface 111. The locking surface 111 and a side surface of the locking portion 11 away from the central axis of the main body 1 are smoothly transitioned through a connecting surface 112. Figure 2 and Figure 3In the example, the outer peripheral surface of the connection surface 112 is roughly arc-shaped. During the process of inserting the contact 100 into the housing 201, the locking portion 11 is in a pressed state. When the contact 100 moves to the point where the free end of the locking portion 11 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 setting of the connection surface 112 is conducive to the right end of the locking portion 11 sliding and tilting upward, thereby improving the assembly rate of the locking portion 11 and the housing 201, and further improving the assembly efficiency of the first connector 200. In addition, during the assembly process of the contact 100 and the housing 201, the connection surface 112 can be prevented from scratching the staff, thereby improving the safety of the contact 100.

[0065] According to some embodiments of the present invention, referring to Figure 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.

[0066] For example, in Figure 4 In the example, the length of the connection surface 112 in the left-right direction is S. When the length S of the connection surface 112 in the direction of the central axis of the main body 1 is less than half of the thickness T of the locking portion 11, the length S of the connection surface 112 in the direction of the central axis of the main body 1 is small, thereby reducing the smoothness of the right end of the locking portion 11 sliding upward and tilting 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 connection surface 112 and the side of the locking portion 11 away from the center of the main body 1 is sharp, or the connection between the connection surface 112 and the locking surface 111 is sharp, thereby during the assembly of the contact 100 and the housing 201, the right end of the locking portion 11 is easy to scratch 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 right end of the locking portion 11 sliding upward and tilting during the assembly of the housing 201 and the contact 100, thereby improving the assembly rate 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 the staff during the assembly of the contact 100 and the housing 201, thereby improving the safety of the contact 100.

[0067] According to some embodiments of the present invention, referring to Figure 1A 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. 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 one side of the outer peripheral surface of the main body 1 adjacent to the center of the main body 1, and the other end of the locking portion 11 is suitable for stopping with the limiting protrusion 1221.

[0068] For example, in Figure 1 In the example, the first side wall 121 is the left side wall of the opening 12, the second side wall 122 is the right side wall of the opening 12, the left end of the locking portion 11 is connected to the first side wall 121, and the right end of the locking portion 11 is located above the limiting protrusion 1221. When a part of the main body 1 is extended into the housing 201, the locking portion 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 portion 11 is stopped against the limiting protrusion 1221. Therefore, 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 the downward movement of the locking portion 11, and preventing the right end of the locking portion 11 from being unable to move upward to restore to the original position due to excessive yielding of the right end of the locking portion 11, thereby effectively improving the cooperation between the locking portion 11 and the housing 201.

[0069] According to some embodiments of the present invention, referring to Figure 4 , 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, wherein G satisfies: 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 stops against the limiting protrusion 1221, the right end of the locking portion 11 is easy to contact with the housing 201, thereby hindering the contact 100 from being assembled 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 and increasing the deformation degree of the locking portion 11, which will make 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.

[0070] Thus, by setting 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 to satisfy 1 / 3T≤G≤1 / 2T, the limiting protrusion 1221 is reasonably set, so that when the right end of the locking portion 11 stops against the limiting protrusion 1221, the difficulty of assembling the contact 100 and the housing 201 is reduced, and the assembly efficiency of the first connector 200 is improved. In addition, the downward movement distance of the right end of the locking portion 11 is shortened, thereby reducing the deformation degree of the locking portion 11, and then it is easy for the right end of the locking portion 11 to return to the original position, and the height of the locking portion 11 in the locked state is increased.

[0071] The traditional contact structure does not have the limiting protrusion 1221 of this solution and the free end of the locking part does not have the beveled locking surface 111. This contact structure is a plate that is pre-punched and cut, the locking part and the housing are cut at the corresponding positions, and then the locking part is stamped and bent to a corresponding height, and then the locking part is hung with the inner wall of the housing. The above technical solution is actually compared with the solution of this application, and the results are as follows (refer to Figure 1 ):

[0072]

[0073] According to the data in the table, it can be concluded that the limiting protrusion 1221 is provided on the main body 1 of the contact 100, which can effectively reduce the yield amount 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 and collapsed, which is conducive to the locking surface 111 of the locking portion 11 and the stop surface 2011 of the shell 201.

[0074] Optionally, refer to Figure 1 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 is oriented toward the central axis direction of the main body 1 (such as Figure 1 With such arrangement, during the assembly of the first connector 200 and the second connector 301, it is possible to ensure that the second connector 301 is in contact with the elastic contact piece 15, which facilitates the insertion of the second connector 301 into the first connector 200, and the second connector 301 can also be smoothly pulled out of the first connector 200, thereby facilitating the assembly and disassembly of the first connector 200 and the second connector 301.

[0075] Optionally, refer to Figure 1A crimping piece 16 is formed on the main body 1. The crimping piece 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. From left to right, the conductor clamp 161 and the insulating clamp 162 are arranged in sequence. When the contact 100 is used in the first connector 200, the two free ends of the insulating clamp 162 are close to each other to fix the wire, the insulating shells of multiple wires are in contact with 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 are in contact with the conductor clamp 161. The two free ends of the conductor clamp 161 are close to each other so that the outer peripheral surface of the conductor clamp 161 is roughly annular, and the multiple wires are wrapped in the conductor clamp 161. Therefore, it is convenient to connect the crimping piece 16 with the wire, thereby facilitating the use of the contact 100. In addition, while facilitating normal conduction of the wire, the connection between the crimping piece 16 and the wire is relatively tight, and the use safety of the contact 100 is improved by providing the insulating wire clamp 162 .

[0076] Further, refer to Figure 6 The main body 1 is formed by a sheet structure, and the main body 1 includes a first side 17, a second side 18 and two third sides 19. The first side 17 is the top side of the main body 1, the opening 12 is formed on the first side 17, and penetrates the upper side and the lower side of the first side 17 in the up-down direction, the second side 18 is the bottom side of the main body 1, and the third side 19 is located between the first side 17 and the second side 18, and the main body 1 is roughly cylindrical. Therefore, the main body 1 has a simple structure and is easy to form, thereby improving the production efficiency of the main body 1.

[0078] According to the first connector 200 of the present invention, by adopting the above-mentioned contact 100, the use stability of the first connector 200 is improved and the service life of the first connector 200 is extended.

[0079] According to some embodiments of the present invention, referring to Figure 1 , the first connector 200 further includes a shell 201.

[0080] 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.

[0081] For example, in Figure 1 In the example, the mating channel 2012 penetrates the housing 201 along the axial direction of the housing 201, the left side portion of the main body 1 extends from the right end of the housing 201 into the mating channel 2012, and the upper side wall of the mating channel 2012 is recessed upward to form a receiving groove 2013, the receiving groove 2013 is opposite to the locking portion 11, the stop surface 2011 is located on the right wall surface of the receiving groove 2013, and the locking surface 111 is suitable for abutting against the stop surface 2011 to limit the rightward movement of the main body 1. Such a configuration is conducive to the assembly of the housing 201 and the contact 100, thereby improving the assembly efficiency of the first connector 200. In addition, it can prevent the main body 1 from falling off from the housing 201, thereby improving the assembly stability of the contact 100 and the housing 201, and further improving the use stability of the first connector 200. In addition, the housing 201 has a simple structure, which reduces the production difficulty of the housing 201, thereby reducing the production cost of the housing 201.

[0084] According to some embodiments of the present invention, referring to Figure 7 The connector assembly 300 further includes a second connector 301, which extends from the other end of the housing 201 of the first connector 200 into the body 1 of the contact 100 of the first connector 200. For example, in Figure 7 In the example, the second connector 301 extends from the left end of the housing 201 into the body 1 of the contact 100, and the second connector 301 contacts the elastic contact piece 15 on the body 1, so that a conductive loop is formed between the first connector 200 and the second connector 301. Thus, the stability of the electrical connection between the first connector 200 and the second connector 301 is improved, thereby improving the stability of the connector assembly 300 in use.
