Detailed Implementation

[0043] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. 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.

[0044] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0045] Furthermore, the terms "long," "short," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0046] The following is in conjunction with the appendix Figure 1-10 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0047] Reference Figure 1 and Figure 2 A terminal connector includes a male terminal module 1, which includes a male terminal contact 11 and a male terminal housing 12. In this embodiment, the male terminal housing 12 is used to provide a mounting position for the male terminal contact 11 and has a block-shaped profile.

[0048] The male end housing 12 has a first mounting hole 3 through it. The first mounting hole 3 opens on opposite sides of the male end housing 12. The male end contact 11 can be inserted into the first mounting hole 3, and the first mounting hole 3 can position it to achieve installation. Alternatively, the male end contact 11 can be removed from the first mounting hole 3 to achieve disassembly of the male end contact 11. On the one hand, it can realize the quick disassembly and assembly function of the male end contact 11, and the assembly is efficient and fast. On the other hand, it can also facilitate the replacement of the male end contact 11, and the replacement process is also efficient and fast.

[0049] Meanwhile, the male end housing 12 is provided with a first louver 13 and a second louver 14 on opposite sides, and the first mounting hole 3 is located between the first louver 13 and the second louver 14. This means that the male end contact piece 11, which is placed in the first mounting hole 3, is also located between the two. The first louver 13 and the second louver 14 can be opened or closed to each other.

[0050] When the first louver 13 and the second louver 14 are opened to each other, the male end contact piece 11 can be detachably installed in the first mounting hole 3, which facilitates the removal and placement of the male end contact piece 11 in the first mounting hole 3.

[0051] When the first louver 13 and the second louver 14 are closed together, the first louver 13 and the second louver 14 can partially close the opening end of the first mounting hole 3, so that the male end contact piece 11 is fixedly disposed on the male end housing 12 and located in the first mounting hole 3. At the same time, the first louver 13 and the second louver 14 can also limit the male end contact piece 11 to prevent the male end contact piece 11 from loosening from the male end housing 12.

[0052] By adopting the above technical solution, only two main components, male contact 11 and male housing 12, are needed in the assembly process of the terminal connector. Moreover, the assembly process does not require complex steps such as bonding, encapsulation, and splicing of multiple housings. The overall number of parts is reduced, the production cost of each component is optimized and thus reduced, and the installation process is quick and convenient, thus solving the problem of complex installation.

[0053] Reference Figure 3 To ensure that the first louver 13 and the second louver 14 can be stably kept closed, the male end housing 12 is provided with a fastening part 15, which is located between the first louver 13 and the second louver 14, and the fastening part 15 is provided with a first fastening position 16.

[0054] Specifically, the latching part 15 is integrally connected to the male end housing 12, and the first fastening position 16 is located on the side of the latching part 15 away from the male end housing 12. The number of the first fastening positions 16 is set to two, and the two first fastening positions 16 are respectively located on opposite sides of the latching part 15. The two first fastening positions 16 are respectively arranged opposite to the first louver part 13 and the second louver part 14.

[0055] Meanwhile, the first louver 13 and the second louver 14 are respectively provided with a second fastening position 17 corresponding to the first fastening position 16, and the first fastening position 16 and the second fastening position 17 are movably fastened together. Specifically, the second fastening position 17 on the first louver 13 is fastened together with the first fastening position 16 near the first louver 13, and the second fastening position 17 on the second louver 14 is fastened together with the first fastening position 16 near the second louver 14.

[0056] In one optional embodiment, the first fastening position 16 is a fastening boss structure, and the second fastening position 17 is a fastening notch structure. The fastening notch is provided through the first louver 13 and the second louver 14. At this time, the fastening boss and the fastening notch can fasten each other, and with the cooperation between the fastening boss and the fastening notch, a quick fastening function can be achieved, and the fastening effect is firm and not easy to loosen.

[0057] In another alternative implementation, the shapes of the first snap-fit ​​position 16 and the second snap-fit ​​position 17 can be interchanged. For example, the first snap-fit ​​position 16 can be a through-hole snap-fit ​​notch, while the second snap-fit ​​position 17 can be a snap-fit ​​boss structure. With the cooperation of the snap-fit ​​boss and the snap-fit ​​notch, a fast and stable snap-fit ​​effect can also be achieved.

[0058] Alternatively, the first snap-fit ​​16 and the second snap-fit ​​17 can be directly set on the first louver 13 and the second louver 14 respectively. With the interaction of the first snap-fit ​​16 and the second snap-fit ​​17, the first louver 13 and the second louver 14 can be directly snapped together, which can also achieve the effect of limiting the male contact piece 11.

[0059] Therefore, regardless of the fastening structure of the first fastening position 16 and the second fastening position 17, and regardless of their specific location, any form that enables the first louver 13 and the second louver 14 to be fastened and connected to each other should be included within the scope of this solution.

[0060] Reference Figure 4 To ensure the male contact piece 11 is positioned within the first mounting hole 3, a first limiting protrusion 31 is provided on the inner wall of the first mounting hole 3. Typically, the first limiting protrusion 31 is integrally connected to the male housing 12, and is located on the side of the first mounting hole 3 away from the first louver 13 and the second louver 14. When the male contact piece 11 is inserted into the first mounting hole 3, one end of the male contact piece 11 contacts the first limiting protrusion 31. At this time, the first limiting protrusion 31 abuts against and limits the male contact piece 11. Combined with the limiting effect of the first louver 13 and the second louver 14, this prevents the male contact piece 11 from detaching from the openings at both ends of the first mounting hole 3, thus achieving a fixed installation of the male contact piece 11.

[0061] Furthermore, looking back Figure 3 Due to structural tolerances, the male contact piece 11 located in the first mounting hole 3 may be loose or wobbly, which may affect the conductivity of the male contact piece 11. Therefore, the first louver 13 and / or the second louver 14 are provided with reinforcing protrusions 18.

[0062] Typically, the reinforcing protrusion 18 is integrally connected on the first louver 13 or the second louver 14. When the first louver 13 and the second louver 14 are closed together, the reinforcing protrusion 18 is used to press and reinforce the male end contact piece 11 toward the inside of the first mounting hole 3, making the male end contact piece 11 less prone to shaking and improving structural stability.

[0063] For example, the reinforcing protrusion 18 has at least three configuration scenarios:

[0064] In the first configuration scenario, the reinforcing protrusion 18 is only provided on the first louver 13. At this time, when the first louver 13 and the second louver 14 are closed, the reinforcing protrusion 18 on the first louver 13 presses and reinforces the male end contact piece 11.

[0065] In the second configuration scenario, the reinforcing protrusion 18 is only provided on the second louver 14. At this time, when the first louver 13 and the second louver 14 are closed, the reinforcing protrusion 18 on the second louver 14 presses and reinforces the male end contact piece 11.

[0066] In the third configuration scenario, the reinforcing protrusion 18 is simultaneously disposed on the first louver 13 and the second louver 14. When the first louver 13 and the second louver 14 are closed, the reinforcing protrusion 18 located on the first louver 13 and the second louver 14 respectively presses and reinforces the male end contact piece 11 on both sides.

[0067] It is understood that in the above embodiments, the specific setting position of the reinforcing protrusion 18 can be adjusted according to actual needs. Regardless of the configuration method, it can achieve the effect of pressing and reinforcing. However, when the reinforcing protrusion 18 is respectively set on the first louver 13 and the second louver 14, the male end contact piece 11 can receive pressing and reinforcing force from both sides, and its overall reinforcement effect is better and it is less prone to off-center load, and it can obtain more accurate positional accuracy. In this embodiment, the scheme of setting the reinforcing protrusion 18 on both sides is used as an example.

[0068] Furthermore, referring to Figure 5 To achieve the conduction effect, the male contact 11 provided in this embodiment includes a straight section 111 and a clamping arm section 112. One end of the straight section 111 is fixedly connected to the clamping arm section 112. The clamping arm section 112 includes two elastic clamping arms arranged opposite to each other. The two elastic clamping arms can form a clamping structure. Other contact elements from the outside can be inserted between the elastic clamping arms and clamped by the two elastic clamping arms. This can achieve good connection stability and the structure is not easy to loosen or break the contact.

[0069] Furthermore, looking back Figure 3 To reduce the overall manufacturing cost of the male end shell 12, the first louver 13 is integrally connected to the male end shell 12. Specifically, the two can be integrally connected by injection molding. Furthermore, there is a first hinge edge (not shown in the figure) between the first louver 13 and the male end shell 12. The first louver 13 folds along the first hinge edge. It can be understood that, in order to form the hinge edge structure, a thin-walled connection area can be set between the first louver 13 and the male end shell 12. This allows the first louver 13 to overcome the yield strength of the material and form plastic deformation. Since the plastic material has good toughness, the bending function of the first louver 13 can be realized.

[0070] Meanwhile, the second louver 14 is integrally connected to the male end housing 12. The second louver 14 and the male end housing 12 have a second hinge edge (not shown in the figure). The setting method of the second hinge edge is similar to that of the first hinge edge, and will not be described in detail here.

[0071] Based on the above configuration, the male end shell 12, the first louver 13, and the second louver 14 can be obtained simultaneously in a single injection molding process. The production process is fast and efficient, and the production cost caused by multiple injection molding processes can be reduced. The number of parts is significantly reduced, and the production cost is further reduced.

[0072] It should be explained that, depending on the different port requirements of the connector, the male contact 11 and the first mounting hole 3 can be set in multiple groups, such as two groups, three groups, five groups, eight groups, etc. Correspondingly, the specific number of the first latch 16, the second latch 17 and the first limiting protrusion 31 can be adjusted according to actual needs. There is no limitation on the specific number of the above components, and no matter how many male contact 11 and first mounting hole 3 are set, they should all be included in the equivalent interpretation of the technical solution of this application.

[0073] Reference Figure 6 In the embodiments of this application, a female terminal module 2 is further provided, which is pluggably connected to the male terminal module 1 described above. The female terminal module 2 includes a female terminal contact 22 and a female terminal housing 21. In this embodiment, the female terminal housing 21 is generally in the form of a block structure, and a positioning notch 4 is recessed on one side of the female terminal housing 21. The shape and size of the positioning notch 4 are adapted to the shape and size of the male terminal housing 12, so that the male terminal housing 12 can be inserted into the positioning notch 4 to realize the pluggable connection between the male terminal module 1 and the female terminal module 2.

[0074] Based on this, combined Figure 7 The female end housing 21 is also provided with a second mounting hole 5, and the female end contact piece 22 is detachably disposed in the second mounting hole 5. When the male end housing 12 and the female end housing 21 are plugged and unplugged, the male end contact piece 11 and the female end contact piece 22 come into contact with each other, thereby achieving a conduction effect.

[0075] Furthermore, referring to Figure 7 and Figure 8To facilitate quick installation of the female contact piece 22, a snap-fit ​​hole 6 is provided through the female contact piece 22. In this embodiment, the snap-fit ​​hole 6 is located at the middle of the female contact piece 22. In addition, the inner wall of the second mounting hole 5 is provided with a second limiting protrusion 51. Normally, the second limiting protrusion 51 is integrally connected with the female outer shell 21. In this embodiment, the second limiting protrusion 51 has a wedge-shaped block structure with an inclined surface on one side. Based on this, the snap-fit ​​hole 6 is movably snapped into the second limiting protrusion 51.

[0076] Based on the above settings, during the installation of the female contact piece 22, the female contact piece 22 can be inserted from one end of the second mounting hole 5. At this time, the female contact piece 22 slides against the inclined surface and forms a certain elastic deformation to further insert into the second mounting hole 5. Until the second limiting protrusion 51 is displaced to the fastening hole 6, the fastening hole 6 accommodates the second limiting protrusion 51, the female contact piece 22 elastically resets, and finally snaps into the second mounting hole 5 to achieve installation. The whole process is quick and convenient and can meet the actual needs of quick assembly of the female module 2.

[0077] Reference Figure 8 Depending on actual needs, the female contact 22 can be configured in various ways. In one of these configurations, the female contact 22 is a straight-line contact blade with an overall straight-line blade structure. One end can be directly inserted between the two elastic clamping arms of the male contact 11. This female contact 22 is relatively simple to manufacture and has a low cost.

[0078] In another implementation, refer to Figure 9 The female contact piece 22 can also be a Y-type contact piece. It can be understood that the general structure of this type of contact piece is the same as that of the straight type. The difference is that one end of the female contact piece 22 is provided with a connecting spring arm 221, which can swing elastically. At this time, the female contact piece 22 is connected to the male contact piece 11 through the connecting spring arm 221. Specifically, the connecting spring arm 221 is inserted into two elastic clamping arms, which can obtain a tighter connection stability, better contact, and less loosening.

[0079] At the same time, combined Figure 7 One end of the connecting spring arm 221 on the Y-shaped contact piece can further abut against the female end housing 21 to prevent the female end contact piece 22 from detaching from the female end housing 21, thereby further improving the installation stability of the female end contact piece 22.

[0080] Furthermore, during the process of plugging and unplugging the male module 1 and the female module 2, there may be cases of reverse insertion or incorrect insertion, which may cause deformation or even breakage of the contact pieces. In order to avoid the phenomenon of incorrect insertion,

[0081] Reference Figure 10The female end shell 21 and the male end shell 12 are pluggable to each other. The female end shell 21 has a first anti-misfit part 7. In this embodiment, the anti-misfit part of the female end shell 21 is located on one side of its circumferential direction. At the same time, the male end shell 12 is provided with a second anti-misfit part 8 that is adapted and positioned to match the first anti-misfit part 7. Correspondingly, the second anti-misfit part 8 is also located on one side of the male end shell 12 in the circumferential direction. The positions of the first anti-misfit part 7 and the second anti-misfit part 8 correspond to each other. In this embodiment, the first anti-misfit part 7 is a concave rib structure and the second anti-misfit part 8 is a convex rib structure. With the cooperation of the concave rib and the convex rib, the anti-misfit pluggable function of both can be realized to avoid the problem of incorrect installation or reverse installation, and the service life of the structure is guaranteed.

[0082] It is understood that in practical applications, the specific structures of the first foolproof part 7 and the second foolproof part 8 can also be configured in opposite ways. The specific structures of the first foolproof part 7 and the second foolproof part 8 are not limited here. As long as the plugging and unplugging foolproof function between the male end housing 12 and the female end housing 21 can be realized, their structures should be included in the equivalent interpretation scope of this application. They will not be listed one by one here.

[0083] The terminal connector provided in this application has the following beneficial effects:

[0084] 1. It has few parts, low manufacturing cost, and simple and quick installation process.

[0085] 2. The structure is stable and easy to install, and is not prone to loosening or disconnection. The connection quality is excellent.

[0086] 3. Both male module 1 and female module 2 have foolproof connection function, which makes it less likely to cause problems such as incorrect installation or reverse installation, and the overall service life can be well guaranteed.

[0087] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
