Description

Technical Field

[0001] This application relates to the technical field of connectors, and more particularly to a connector. Background Technology

[0002] Connectors are the core connecting components between the control and execution ends, playing a crucial role in the transmission of current and control signals.

[0003] Connectors typically consist of a housing, terminal assemblies, and locking components. The terminal assemblies are inserted into the housing and then locked in place by the locking components. Currently, hard extrusion or interference-fit connections are commonly used for fixing, which results in a relatively rough assembly process, insufficient precision, and inadequate assembly quality.

[0004] Application content

[0005] This application provides a connector to ensure the accuracy of connector assembly and guarantee assembly quality.

[0006] This application provides a connector having a first direction. The connector includes: a housing having at least one mounting cavity extending along the first direction, with a plug-in interface provided at one end of the mounting cavity; a latching member resiliently disposed on the inner wall of the mounting cavity; a terminal assembly inserted into the mounting cavity along the plug-in interface, the terminal assembly having a latching portion, the latching member engaging with the latching portion to limit the position of the terminal assembly along the first direction; a clamping member disposed on the side of the latching member near the plug-in interface, the clamping member abutting against the latching member to press the latching member against the latching portion; and a locking member connected to the side of the housing located at the plug-in interface, the locking member abutting against the clamping member to press the clamping member against the outside of the latching member; wherein the clamping member includes a pressing portion and a limiting portion interconnected, the limiting portion being disposed on the side of the pressing portion near the plug-in interface, and a stop portion being provided inside the housing, the limiting portion and the stop portion abutting against each other in the first direction to limit the position of the clamping member.

[0007] One of the above technical solutions has the following advantages or beneficial effects: In this application, the latching member and the latching part cooperate to form a locking structure for the terminal assembly, reducing the movement of the terminal assembly along the first direction. The clamping member presses against the latching member, making the cooperation between the latching member and the latching part more reliable and stable, enhancing the stability of the locking structure. Finally, the locking member is used to limit the position of the clamping member to complete the assembly of the male connector. In this embodiment, a stop part is provided on the inner wall of the housing to abut against the limiting part of the clamping member. Therefore, when installing the clamping member, the installation position of the clamping member can be accurately positioned by the constraint of the stop part, ensuring the effectiveness of the clamping member's constraint on the latching member and the latching part. This avoids inaccurate installation or clamping damage caused by excessive clamping force between the clamping member and the latching member, or avoids insufficient clamping force, which makes it difficult to guarantee the stability of the latching cooperation between the latching member and the latching part.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the term "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Furthermore, the character " / " in this document, unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0026] The following is in conjunction with the appendix Figure 1-8 This application will be further described below.

[0027] Reference Figures 1-3 This application provides a connector with intersecting first direction X and second direction Y. The connector includes a housing 1, a snap-fit ​​member 2, a clamping member 4, a terminal assembly 3, a sealing member 6, and a locking member 5. In some examples, the first direction X is parallel to the length direction of the terminal assembly 3, and the second direction Y is perpendicular to the first direction X. The terminal assembly 3 is inserted into the housing 1 and initially fixed by the snap-fit ​​member 2. The locking member 5 presses the sealing member 6 and the clamping member 4 onto the snap-fit ​​member 2 to achieve secondary reliable fixing of the terminal assembly 3 and ensure the stability of the terminal assembly 3 assembly.

[0028] Specifically.

[0029] Reference Figure 2 , Figure 3 and Figure 4 The housing 1 is rectangular in shape and has at least one mounting cavity 10 extending along a first direction X. One end of the mounting cavity 10 is provided with a plug-in interface 100. In one example, there are two mounting cavities 10, and the ends of the two mounting cavities 10 away from the plug-in interface 100 are separated by a snap-fit ​​member 2, thereby allowing two terminal assemblies 3 to be plugged in and engaged. The terminal assemblies 3 enter the mounting cavity 10 through the plug-in interface 100 and complete the plug-in engagement. In some other alternative embodiments, there may be more mounting cavities 10 to allow more terminal assemblies 3 to be plugged in and engaged.

[0030] Terminal assembly 3 is inserted into mounting cavity 10 along insertion interface 100. Terminal assembly 3 is provided with latching portion 30, and latching member 2 engages with latching portion 30 to limit the position of terminal assembly 3 along first direction X. In some examples, terminal assembly 3 includes cable 31 and shielding shell 32. Shielding shell 32 covers the outside of cable 31, and at least a portion of shielding shell 32 is recessed toward cable 31 to form latching portion 30.

[0031] It is understandable that the snap-fit ​​of the latching member 2 and the snap-fit ​​part 30 is used to limit the displacement of the terminal assembly 3 along the first direction X. Therefore, the snap-fit ​​part 30 should be a recessed space along the second direction Y, and the snap-fit ​​member 2 should be a structure that protrudes along the second direction Y, so that the snap-fit ​​in the second direction Y can play a limiting function.

[0032] The latching member 2 is elastically disposed on the inner wall of the mounting cavity 10. In some examples, the latching member 2 is configured as a spring and integrally connected to the inner wall of the mounting cavity 10. One end of the latching member 2 is elastically connected to the inner wall of the mounting cavity 10, and the other end of the latching member 2 is configured as a hook, thereby engaging with the recessed latching portion 30. Furthermore, in the second direction Y, a gap 20 is left between the latching member 2 and the inner wall of the mounting cavity 10, wherein the size of the gap 20 gradually increases from the connection position toward the insertion interface 100, and at least a portion of the clamping member 4 is accommodated within the gap 20 to compress the latching member 2 in the second direction Y.

[0033] In this embodiment, the latching member 2 and the latching part 30 cooperate to form a locking structure for the terminal assembly 3, reducing the movement of the terminal assembly 3 along the first direction X. The clamping member 4 presses against the latching member 2, making the cooperation between the latching member 2 and the latching part 30 more reliable and stable, thereby enhancing the stability of the locking structure and ensuring the reliability of the terminal assembly 3 connected to the housing 1. The clamping member 4 is disposed on the side of the latching member 2 near the insertion interface 100, and the clamping member 4 abuts against the latching member 2 to press the latching member 2 against the latching part 30. The locking member 5 is connected to the side of the housing 1 located at the insertion interface 100, and the locking member 5 abuts against the clamping member 4 to press the clamping member 4 against the outside of the latching member 2. The locking member 5 is used to restrict the position of the clamping member 4 to complete the assembly of the male connector.

[0034] Reference Figure 4 , Figure 5 and Figure 6 The clamping member 4 includes a pressing part 42 and a limiting part 41 connected to each other. The limiting part 41 is disposed on the side of the pressing part 42 near the insertion interface 100. A stop part 11 is disposed inside the housing 1. The limiting part 41 and the stop part 11 abut against each other in the first direction X to limit the position of the clamping member 4.

[0035] In some examples, the limiting part 41 is plate-shaped, the thickness direction of the limiting part 41 is parallel to the first direction X, and a through hole is provided on the limiting part 41 along the first direction X. The crimping part 42 is cylindrical and is connected to the limiting part 41. The interior of the crimping part 42 and the through hole on the limiting part 41 together form a passage cavity 40 for the cable 31 to pass through.

[0036] In this embodiment, a stop part 11 is provided on the inner wall of the outer shell 1 to abut against the limiting part 41 of the clamping member 4. Therefore, when installing the clamping member 4, the installation position of the clamping member 4 can be accurately positioned by the constraint of the stop part 11, ensuring the effectiveness of the clamping member 4 in constraining the buckle 2 and the buckle part 30. This avoids inaccurate installation or buckling damage caused by excessive pressing force between the clamping member 4 and the buckle 2, or insufficient pressing force of the clamping member 4, which would make it difficult to ensure the stability of the buckling fit between the buckle 2 and the buckle part 30.

[0037] When installing this connector, first insert the cable 31 into the mounting cavity 10, and the latching member 2 and the latching part 30 will engage. Then, install the clamping member 4, and insert the crimping part 42 into the gap 20. Due to the design of the gap 20, as the crimping part gradually penetrates into the gap 20, it will cause the crimping part to press the latching member 2 along the second direction Y, thereby enhancing the engagement stability and reliability of the latching member 2 and the latching part 30.

[0038] The specific installation process is as follows:

[0039] Installing terminal assembly 3: The operator holds or uses a machine to clamp the terminal assembly 3 and inserts it into the mounting cavity 10 through the insertion interface 100 until the latching part 2 and the latching part 30 are engaged and connected. At this time, the initial installation of the two terminal assemblies 3 is completed. During this process, the operator or the machine can judge whether the installation is in place by the contact between the stop part 11 and the limit part 41.

[0040] Install the clamping component 4 and the sealing component 6. The operator holds or uses a machine to clamp the clamping component 4 so that the cable 31 passes through the passage cavity 40. The clamping component 4 is then inserted into the outer shell 1 through the plug interface 100. Similarly, the sealing component 6 is clamped so that the cable 31 passes through the sealing cavity 60. The sealing component 6 is then inserted into the outer shell 1 through the plug interface 100.

[0041] Install the locking element 5 and fix it to the housing 1. The locking element 5 presses against the sealing element 6 and the clamping element 4 to ensure the reliability of the terminal assembly 3.

[0042] As one optional embodiment of this application, a flange 401 is provided on the inner wall of the cavity 40, and the flange 401 abuts against the shielding shell 32 in the first direction X. In one example, the crimping part 42 is divided into a first segment 421 and a second segment 422 along the first direction X, wherein the second segment 422 is connected to the side of the first segment 421 near the insertion interface 100, and the inner diameter of the second segment 422 is smaller than the inner diameter of the first segment 421, so that a stepped flange 401 structure is formed at the joint between the second segment 422 and the first segment 421.

[0043] To achieve the above technical solution, after the clamping component 4 is installed, the flange 401 abuts against the shielding shell 32 in the first direction X, thereby further restricting the movement of the terminal assembly 3, thus ensuring the reliability and stability of the assembly of the terminal assembly 3 and the shell 1.

[0044] Back Figure 4 As one optional embodiment of this application, the inner wall portion of the outer casing 1 protrudes to form a stop portion 11, and a weight-reducing groove 110 is provided on the stop portion 11, which extends along the first direction X. The peripheral outer wall of the pressing portion 42 abuts against the stop portion 11 and the inner wall of the mounting cavity 10, and the peripheral outer wall of the limiting portion 41 abuts against the inner wall of the mounting cavity 10.

[0045] It is understandable that the outer peripheral wall of the crimping part 42 abuts against the stop part 11 and the inner wall of the mounting cavity 10, meaning that the crimping part 42 is configured as a sleeve, the recessed space formed between the two crimping parts 42 is engaged with the stop part 11, and the other parts of the crimping part 42 are in contact with the inner wall of the outer shell 1.

[0046] To achieve the above technical solution, the stop part 11, through its structural design, not only forms abutment with the limiting part 41 to limit the position of the clamping member 4, but also reduces material consumption, thereby effectively reducing production costs. Furthermore, the peripheral outer wall of the pressing part 42 is limited by the stop part 11 and the mounting cavity 10, ensuring the stability of the clamping member 4 when it is placed inside the housing 1, preventing the clamping member 4 from jumping in the second direction Y, thus ensuring the limiting constraint on the terminal assembly 3 and improving the overall structural stability.

[0047] Reference Figure 2 , Figure 3 and Figure 7As one optional embodiment of this application, the locking member 5 includes a closing part 51, an abutting part 52, and a connecting part 53. The connecting part 53 is fixedly connected to the outer shell 1. The closing part 51 covers the insertion interface 100, and the abutting part 52 is used to abut against the pressing member 4. In one example, the closing part 51 is plate-shaped, the connecting part 53 is disposed in the circumference of the closing part 51 and extends along the first direction X, a protrusion is provided on the outer side wall of the outer shell 1, and a connecting hole is provided on the connecting part 53 to engage with the protrusion to fix the connecting part 53 to the outer shell 1.

[0048] To achieve the above technical solution, a specific structure for the locking member 5 is proposed. The closing part 51 closes the insertion interface 100, and the locking member 5 is fixedly connected to the outer shell 1 through the connecting part 53, so that the abutting part 52 can provide a stable compressive force to the pressing member 4. The structure is simple and reliable.

[0049] As one of the optional embodiments of this application, the sealing part 51 is provided with a plurality of sealing holes 50 for the matching terminal assembly 3, the sealing holes 50 being isolated from each other, and the abutting part 52 includes a plurality of abutting blocks, the plurality of abutting blocks being arranged at intervals along the circumference of the sealing holes 50.

[0050] To achieve the above technical solution, the abutment blocks are spaced circumferentially along the closed holes 50, which effectively saves materials and reduces production costs while ensuring uniform pressing of the clamping parts 4. Furthermore, the abutment part 52 is sleeve-shaped as a whole, and after assembly, it can be sleeved on the outside of the terminal assembly 3, thereby limiting the radial runout of the terminal assembly 3 and ensuring the stability of the terminal assembly 3 installation.

[0051] Reference Figure 2 , Figure 3 and Figure 8 As one of the optional embodiments of this application, the sealing member 6 is disposed on the side of the clamping member 4 near the insertion interface 100, and the locking member 5 abuts the sealing member 6 against the clamping member 4 along the first direction X, and the outer peripheral side of the sealing member 6 abuts against the inner wall of the mounting cavity 10.

[0052] As one of the optional embodiments of this application, the sealing member 6 is provided with a sealing cavity 60 for the cable 31 to pass through. The sealing cavity 60 is disposed through the sealing member 6 along the first direction X. The inner wall of the sealing cavity 60 is provided with a plurality of sealing rings 601, which are spaced apart along the first direction X. The sealing rings 601 abut against the outer wall of the cable 31.

[0053] To achieve the above technical solution, the sealing element 6 can isolate the interior of the mounting cavity 10 from the outside, thereby providing good sealing performance for the terminal assembly 3. In humid or water-prone environments, it can effectively ensure the electrical conductivity of the terminal assembly 3, thus guaranteeing its service life and performance. In some examples, two sealing cavities 60 are provided corresponding to the terminal assembly 3. The two sealing cavities 60 are spaced apart and independent of each other. This ensures the independence of the sealing cavities 60, so that when the sealing performance of one terminal assembly 3 deteriorates, the sealing performance of the other sealing cavity 60 will not be significantly affected.

[0054] The above description is only a partial implementation of the embodiments of this application and is not intended to limit the application in any way. The protection scope of the embodiments of this application is not limited thereto. Any simple modifications, equivalent changes and alterations that can be easily conceived by those skilled in the art within the technical scope disclosed in the embodiments of this application should be included within the protection scope of the embodiments of this application.
