In this solution, locking is achieved by switching the first and second limiting members to different positions.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] The technical solutions disclosed in the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 5 As shown in the figure, this utility model embodiment discloses an electrical connector 100, which includes a male connector 110 and a female connector 120.

[0036] Male connector 110 and female connector 120 are configured to be electrically connected. At this time, the circuit structure of male connector 110 and the circuit structure of female connector 120 are mutually conductive.

[0037] The male seat 110 includes a first limiting member 111, which includes a base portion 111a and a first protrusion 111b. The first protrusion 111b is disposed on the outer peripheral surface of the base portion 111a.

[0038] The female seat 120 includes a second limiting member 121, which includes a ring portion 121a and a second protrusion 121b. The ring portion 121a has an inner ring region 121a1, which refers to the area in the middle of the ring portion 121a where there is no solid material. The second protrusion 121b extends from the inner ring surface of the ring portion 121a towards the inner ring region 121a1. That is, the second protrusion 121b is disposed on the inner ring surface of the ring portion 121a and is located in the inner ring region 121a1.

[0039] The annular portion 121a and the base portion 111a are rotatable relative to each other, allowing the first limiting member 111 and the second limiting member 121 to switch between a first position and a second position. Optionally, at least one of the annular portion 121a and the base portion 111a can rotate about the central axis of the annular portion 121a. In this case, one of the annular portion 121a and the base portion 111a can rotate relative to the other, causing a change in the position between the first limiting member 111 and the second limiting member 121. Of course, at least one of the annular portion 121a and the base portion 111a can also rotate about other axes, thereby causing relative rotation between the annular portion 121a and the base portion 111a, which is not limited herein.

[0040] When the second limiting member 121 and the first limiting member 111 are in the first position, the first protrusion 111b and the second protrusion 121b are misaligned. At this time, the first protrusion 111b and the second protrusion 121b do not interfere with each other along the axial direction of the ring portion 121a. Therefore, the first limiting member 111 can pass through the inner ring region 121a1 of the ring portion 121a, so that the first limiting member 111 can move from one side of the ring portion 121a to the opposite side of the ring portion 121a. It should be understood here that the first limiting member 111 passes through the inner ring region 121a1 at a position not blocked by the second protrusion 121b.

[0041] To ensure that the first limiting member 111 can pass through the inner ring region 121a1, the orthographic projection contour of the first limiting member 111 is located within the orthographic projection contour of the inner ring region 121a1 along the axial direction of the ring body portion 121a. Here, the orthographic projection contour of the first limiting member 111 and the orthographic projection contour of the inner ring region 121a1 can completely coincide, allowing the first limiting member 111 to pass through the inner ring region 121a1 within its limit dimensions. Alternatively, the area of ​​the orthographic projection contour of the first limiting member 111 can be smaller than the area of ​​the orthographic projection contour of the inner ring region 121a1, thereby allowing the first limiting member 111 to pass through the inner ring region 121a1 more easily. The orthographic projection contour of the first limiting member 111 mentioned above refers to the projection contour formed by the combination of the orthographic projection contours of the first protrusion 111b and the second protrusion 121b. The ring portion 121a has a first surface and a second surface disposed opposite to each other along its axial direction. The first limiting member 111 can pass through the inner ring region 121a1 of the ring portion 121a, and can move the first limiting member 111 from the side where the first surface of the ring portion 121a is located to the side where the second surface of the ring portion 121a is located.

[0042] When the second limiting member 121 and the first limiting member 111 are in the second position, the first protrusion 111b and the second protrusion 121b are disposed opposite to each other, so that the first limiting member 111 is in a limiting engagement with the second limiting member 121 in the direction toward the second limiting member 121. That is, the first limiting member 111 and the second limiting member 121 can mutually limit each other. At this time, the first limiting member 111 and the second limiting member 121 are in a limiting engagement in the direction from the second surface to the first surface.

[0043] During the specific assembly process, before the male seat 110 and female seat 120 are assembled, the first limiting member 111 is located on the side where the first surface of the ring body portion 121a is located, and at this time, the male seat 110 and female seat 120 are in a separated state. During the assembly process, the first limiting member 111 and the second limiting member 121 are first positioned. At this time, the first protrusion 111b and the second protrusion 121b are misaligned, so that the first limiting member 111 can pass through the inner ring area 121a1 of the ring body portion 121a, thereby moving the first limiting member 111 from the side where the first surface is located to the side where the second surface is located, such as... Figure 1 As shown. Then rotate the first limiting member 111 and the second limiting member 121 to a position where the first protrusion 111b and the second protrusion 121b are opposite each other, as shown. Figure 2 As shown. At this time, the first protrusion 111b and the second protrusion 121b interfere with each other in the direction they approach each other, so that the first limiting member 111 and the second limiting member 121 cannot be separated, thereby achieving the locking of the male seat 110 and the female seat 120.

[0044] In the embodiments disclosed in this application, locking and limiting are achieved by switching the first limiting member 111 and the second limiting member 121 at different positions. Therefore, when the male connector 110 and the female connector 120 are locked, the user is prevented from applying a large pressing force, thereby avoiding the risk of breakage of the first limiting member 111 and the second limiting member 121, and further reducing the risk of failure of the male connector 110 and the female connector 120 to mate, thus improving the safety and reliability of the electrical connector 100.

[0045] Compared to electrical connectors in related technologies, the first limiting member 111 and the second limiting member 121 in this application can overlap in position, thus achieving a locked engagement between the male connector 110 and the female connector 120. This avoids the risk of disengagement. Furthermore, electrical connectors in related technologies use a press-fit method, which can easily lead to loosening of the latch after repeated insertion and removal. In contrast, the first limiting member 111 and the second limiting member 121 in this application use a rotational locking method, thus avoiding the risk of fatigue-induced loosening of the latch.

[0046] In the above scheme, the first limiting member 111 and the second limiting member 121 can be used only to achieve the locking connection between the male connector 110 and the female connector 120. That is, the male connector 110 and the female connector 120 also have corresponding body components. In an optional scheme, the male connector 110 also includes a first body portion, and the first limiting member 111 is disposed on the first body portion. The first body portion includes, but is not limited to, components such as a support base and circuit pins. Similarly, the female connector 120 also includes a second body portion, and the second limiting member 121 is disposed on the second body portion. The second body portion includes, but is not limited to, components such as a support base and circuit pins. In a specific assembly method, the male connector 110 and the female connector 120 are positioned opposite each other, and then the male connector 110 is moved toward the female connector 120. The first limiting member 111 can pass through the inner ring region 121a1 of the ring body portion 121a, thereby allowing the first limiting member 111 to move from the side where the first surface is located to the side where the second surface is located. Then, the first limiting member 111 or the second limiting member 121 is rotated, or the male seat 110 or the female seat 120 can be rotated as a whole, so that the first protrusion 111b and the second protrusion 121b are opposite each other. At this time, the first limiting member 111 is limited between the second body and the second limiting member 121, while the second limiting member 121 is limited between the first body and the first limiting member 111. Thus, the male seat 110 and the female seat 120 are mutually locked and engaged.

[0047] In the above scheme, in order to enable the first limiting member 111 and the second limiting member 121 to rotate relative to each other, there are gaps between the first body part and the first protrusion 111b and between the second body part and the second protrusion 121b, so as to reserve corresponding space for the first limiting member 111 and the second limiting member 121 to rotate relative to each other and stack.

[0048] After the first limiting member 111 and the second limiting member 121 mutually limit and cooperate, the circuit pins on the first body and the circuit pins on the second body can be electrically connected, thus realizing the electrical connection between the male connector 110 and the female connector 120.

[0049] In the above scheme, the male seat 110 can be mounted on the corresponding functional module through the first body part, while the female seat 120 can be mounted on the corresponding functional module through the second body part.

[0050] In one embodiment, the first limiting member 111 can be fixedly connected to the first body portion, and the second limiting member 121 can be fixedly connected to the second body portion. In this case, switching the positions of the first limiting member 111 and the second limiting member 121 can be achieved by directly rotating the male seat 110 or the female seat 120 as a whole. Alternatively, in another optional embodiment, the first limiting member 111 can be rotatably connected to the first body portion. Still another option is that the second limiting member 121 can be rotatably connected to the second body portion.

[0051] In another alternative embodiment, the male connector 110 may further include a plurality of first circuit pins 112, which may be spaced apart on the first limiting member 111. In this case, the circuit pins on the male connector 110 are directly disposed on the first limiting member 111, that is, the first limiting member 111 serves as the mounting base of the male connector 110.

[0052] The female connector 120 may also include a plurality of second circuit pins 122, which are spaced apart on the second limiting member 121. In this case, the circuit pins on the female connector 120 are directly set on the second limiting member 121, that is, the second limiting member 121 serves as the mounting base of the female connector 120.

[0053] When the second limiting member 121 and the first limiting member 111 are in the second position, each first circuit pin 112 is opposite to and electrically connected to its corresponding second circuit pin 122.

[0054] In this scheme, the first limiting member 111 and the second limiting member 121 are both provided with corresponding circuit pins. Therefore, the first limiting member 111 can be used as the body of the male connector 110, and the second limiting member 121 can be used as the body of the female connector 120. This helps to simplify the structure of the male connector 110 and the female connector 120, thereby making the structure of the electrical connector 100 simpler.

[0055] In specific applications, the first limiting member 111 is directly fixed to the first functional module 200. Specifically, one end of the base portion 111a is directly fixed to the first functional module 200. The second limiting member 121 is directly fixed to the second functional module. Specifically, the ring portion 121a is fixed to the second functional module, and the second surface of the ring portion 121a faces the second functional module. When the male connector 110 and the female connector 120 are connected, the first limiting member 111 and the second limiting member 121 are directly aligned and penetrated, and then rotated to achieve the limiting of the male connector 110 and the female connector 120. Here, after the first limiting member 111 and the second limiting member 121 are rotated, the circuit pins on the first limiting member 111 correspond to the circuit pins on the second limiting member 121. That is, the positive pin on the first limiting member 111 corresponds to the positive pin on the second limiting member 121. Similarly, the circuit pins of other functions are also arranged opposite each other.

[0056] After the male seat 110 and the female seat 120 are locked, the first limiting member 111 is located between the second limiting member 121 and the second functional module, and the second limiting member 121 is located between the first limiting member 111 and the second functional module. In order to enable the first limiting member 111 and the second limiting member 121 to rotate relative to each other, there are gaps between the first functional module 200 and the first protrusion 111b and between the second functional module and the second protrusion 121b, so as to reserve corresponding space for the first limiting member 111 and the second limiting member 121 to rotate relative to each other and stack.

[0057] In the above scheme, the first circuit pin 112 can be disposed on the base portion 111a. In this case, the pin corresponding to the first functional module 200 is electrically connected to the first circuit pin 112. The second circuit pin 122 can be disposed on the ring portion 121a. In this case, the pin corresponding to the second functional module can be electrically connected to the second circuit pin 122. Here, the first circuit pin 112 and the second circuit pin 122 can be conductive sheets, gold fingers, solder pads, etc., and of course, other structures are also possible, which are not limited in this article.

[0058] In another alternative embodiment, there may be multiple first protrusions 111b, and the multiple first protrusions 111b may be arranged circumferentially along the base portion 111a, with a first clearance notch 111b1 formed between two adjacent first protrusions 111b.

[0059] There are multiple second protrusions 121b, which are spaced apart circumferentially along the annular portion 121a. A second clearance notch 121a11 is formed between adjacent second protrusions 121b. The ends of the multiple second protrusions 121b facing away from the inner annular surface of the annular portion 121a together form a hollow region 121a12. The base portion 111a is positioned opposite to the hollow region 121a12. In this configuration, the multiple second protrusions 121b divide the inner annular region 121a1 into the hollow region 121a12 and the multiple second clearance notches 121a11, and all the second clearance notches 121a11 are connected to the hollow region 121a12. Alternatively, the inner annular region 121a1 can be understood as including the hollow region 121a12 and the multiple second clearance notches 121a11. Since the base portion 111a and the hollow region 121a12 are arranged opposite to each other, the base portion 111a can pass through the hollow region 121a12. That is to say, the orthographic projection outline of the base portion 111a is located within the orthographic projection outline of the hollow region 121a12.

[0060] When the second limiting member 121 and the first limiting member 111 are in the first position, each second protrusion 121b is opposite to a first clearance notch 111b1, and each first protrusion 111b is opposite to a second clearance notch 121a11. When the second limiting member 121 and the first limiting member 111 are in the second position, each second protrusion 121b is opposite to one of the first protrusions 111b.

[0061] In this design, both the first limiting member 111 and the second limiting member 121 can be circumferentially limited, thus ensuring a relatively balanced force between them and preventing the risk of unilateral tilting. Simultaneously, the one-to-one correspondence between multiple first protrusions 111b and multiple second protrusions 121b further enhances the reliability of the locking mechanism between the male seat 110 and the female seat 120.

[0062] In another optional embodiment, each first protrusion 111b is provided with a first circuit pin 112. In this case, each first protrusion 111b and its corresponding first circuit pin 112 form a pad of the male connector 110. The female connector 120 may also include a plurality of second circuit pins 122, and each second protrusion 121b may be provided with a second circuit pin 122. In this case, each second protrusion 121b and its corresponding second circuit pin 122 form a pad of the female connector 120.

[0063] When the second limiting member 121 and the first limiting member 111 are in the second position, the second circuit pin 122 on each second protrusion 121b is electrically connected to the first circuit pin 112 on the corresponding first protrusion 111b.

[0064] In this scheme, in the second position, the first protrusion 111b and the second protrusion 121b are opposite to each other. Therefore, setting the circuit pins on the first protrusion 111b and the second protrusion 121b can make the corresponding circuit pins be set opposite to each other, thus making it easier to connect the circuit pins.

[0065] like Figure 1As shown, when the second limiting member 121 and the first limiting member 111 are in the first position, the first protrusion 111b and the second protrusion 121b are misaligned, and therefore the corresponding first circuit pin 112 and second circuit pin 122 are also misaligned. When the second limiting member 121 rotates clockwise by a certain angle, each first protrusion 111b is positioned opposite to one of the second protrusions 121b, and therefore the corresponding first circuit pin 112 and second circuit pin 122 are positioned accordingly. For example, both the first circuit pin 112 and the second circuit pin 122 can include circuit pins such as P+, P-, NC, and TH. When the second limiting member 121 rotates clockwise by a certain angle, the P+ pin of the first circuit pin 112 is positioned opposite to the P+ pin of the second circuit pin 122; similarly, other corresponding circuit pins are also positioned opposite each other.

[0066] In the above embodiments, the switching angle between the first position and the second position can be determined according to the number of the first protrusion 111b and the second protrusion 121b. When the number of the first protrusion 111b and the second protrusion 121b is large, the switching angle is small; when the number of the first protrusion 111b and the second protrusion 121b is small, the switching angle is large.

[0067] Furthermore, the second limiting member 121 can be symmetrically arranged about its central axis. Here, the central axis of the second limiting member 121 refers to the central axis of the ring portion 121a. The first limiting member 111 is symmetrically arranged about its central axis. Here, the central axis of the first limiting member 111 refers to the central axis of the base portion 111a. This design allows for a more regular structure of the first limiting member 111 and the second limiting member 121, thereby improving fitting accuracy and reliability.

[0068] In order to improve the fitting accuracy of the first limiting member 111 and the second limiting member 121, in another optional embodiment, the female seat 120 may also include a mounting base 121c and a positioning post 121d. The first limiting part and the positioning post 121d can both be disposed on the mounting base 121c, and the positioning post 121d can be disposed opposite to the inner ring area 121a1.

[0069] The base portion 111a may have a positioning groove 111a1, and at least a portion of the positioning post 121d may be located within the positioning groove 111a1. The positioning post 121d may rotate relative to the positioning groove 111a1 about its central axis. In this design, the positioning post 121d and the positioning groove 111a1 can limit the installation positions of the first limiting member 111 and the second limiting member 121, thereby improving the assembly accuracy of the first limiting member 111 and the second limiting member 121, and further improving the installation accuracy of the electrical connector 100.

[0070] Furthermore, the outer peripheral surface of the positioning post 121d can be provided with an external thread, and the inner sidewall of the positioning groove 111a1 can be provided with an internal thread. When the second limiting member 121 and the first limiting member 111 are in the second position, the internal and external threads engage. In this design, the positioning post 121d and the first limiting member 111 can be threaded together, thereby further improving the connection strength between the male connector 110 and the female connector 120. In addition, the internal and external threads also have a foolproof function, avoiding the risk of misalignment of corresponding circuit pins caused by the reverse rotation of the first limiting member 111 and the second limiting member 121, thus further improving the safety and reliability of the electrical connector 100. Furthermore, by limiting the engagement length of the external and internal threads, the rotation angle of the first limiting member 111 and the second limiting member 121 can also be further limited, avoiding the risk of excessive rotation of the first limiting member 111 and the second limiting member 121.

[0071] In another alternative embodiment, the central axis of the positioning post 121d may coincide with the central axis of the ring body 121a. This arrangement allows the positioning post 121d and the ring body 121a to rotate concentrically, thereby further improving the assembly accuracy of the male seat 110 and the female seat 120.

[0072] In another alternative embodiment, the annular portion 121a is rotatably connected to the mounting base 121c, and the annular portion 121a rotates relative to the mounting base 121c about its central axis. In this embodiment, by setting the annular portion 121a to rotate relative to the mounting base 121c, the overall rotation of the male seat 110 or female seat 120 is avoided.

[0073] Optionally, the mounting base 121c can be fitted onto the annular portion 121a, thereby enabling the annular portion 121a to rotate relative to the mounting base 121c. Alternatively, the mounting base 121c can be provided with an annular track, on which multiple sliders are mounted. These sliders are fixedly connected to the annular portion 121a. In this case, when the annular portion 121a is rotated, the sliders slide on the annular track, thereby enabling the annular portion to rotate.

[0074] To facilitate the rotation of the annular portion, in another alternative embodiment, the second limiting member 121 may also include a rotating rod 121e, which may be disposed on the outer peripheral surface of the annular portion 121a. In this embodiment, the rotating rod 121e can more easily drive the annular portion 121a to rotate, thereby reducing the assembly difficulty of the electrical connector 100.

[0077] Optionally, both the first functional module 200 and the second functional module can be circuit boards, or one of the first functional modules 200 can be a circuit board and the other can be a camera module, receiver, or other devices. Of course, the first functional module 200 and the second functional module can also be other devices, which are not limited in this article.

[0078] The electronic devices disclosed in this application can be smartphones, tablets, e-book readers, wearable devices (such as smartwatches), video game consoles, etc. This application does not limit the specific types of electronic devices.
