Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to a connector. Background Technology

[0002] Connectors are crucial components for transmitting electrical signals in modern electronic devices, and are widely used in communications, computers, automotive electronics, and consumer electronics. To ensure stable signal transmission, connectors typically consist of terminals and a housing.

[0003] However, current connectors suffer from several significant design and manufacturing defects, particularly the lack of an effective fixing structure to position and secure the terminals after assembly with the housing. This issue leads to several shortcomings: First, the lack of a fixing structure prevents accurate positioning and identification of the terminals after installation within the housing, potentially causing inaccuracies in the mating operation and increasing the risk of connection failure. Second, the lack of a fixing structure results in a large gap between the terminals and the shielding, leading to uneven electromagnetic field distribution around the terminals and increasing the risk of electromagnetic interference (EMI). This interference can cause signal reflection, attenuation, or distortion, ultimately affecting signal integrity (SI) and causing data transmission errors or degraded communication quality. Finally, the lack of a fixing structure results in lower connection reliability between the terminals and the housing, making the terminals prone to backward movement during connector mating. This backward movement not only affects the mechanical stability of the connector but can also lead to instability in electrical signal transmission. Utility Model Content

[0004] This application provides a connector that solves the problems of inaccurate terminal positioning and identification, poor signal integrity, and low signal transmission stability in current connectors due to the lack of a fixing structure for positioning and fixing the terminals.

[0005] To achieve the above objectives, this application provides a connector having intersecting first and second directions. The connector includes: a housing having at least one receiving structure, the receiving structure including a communicating receiving opening and a receiving cavity, the receiving opening extending along the first direction and the receiving cavity extending along the second direction; at least one terminal, each terminal being disposed correspondingly within the receiving structure, each terminal including a wiring portion, a plug portion and a bending portion, the wiring portion extending along the first direction and disposed within the receiving opening, the plug portion extending along the second direction and disposed within the receiving cavity, and the bending portion connecting the wiring portion and the plug portion; and a fixing member including at least one fixing portion, each fixing portion being disposed correspondingly within the receiving opening of the receiving structure, and the fixing portion abutting against the wiring portion of the terminal on the side of the terminal away from the plug portion in the second direction.

[0006] The connector of this application features a retaining member within the accommodating opening of the accommodating structure. The retaining part abuts against the side of the wiring portion away from the mating portion in the second direction, enabling accurate positioning and identification of the terminals, improving the connector's precision during mating operations, and reducing the risk of connection failure. The retaining member reduces the gap between the terminals and the first shielding component, effectively suppressing impedance fluctuations, reducing the risk of electromagnetic interference, and improving signal integrity. Furthermore, the retaining member enhances the connection reliability between the terminals and the housing, prevents displacement during connector mating, and improves the connector's mechanical stability and electrical signal transmission stability.

[0021] 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 protection scope of this application.

[0022] Please see Figures 1 to 2This application provides a connector 100. The connector 100 has a first direction M, a second direction N, and a third direction P that intersect each other. In this embodiment, the first direction M, the second direction N, and the third direction P are perpendicular to each other. The perpendicularity of the first direction M, the second direction N, and the third direction P can be understood as the included angle between each pair of the first direction M, the second direction N, and the third direction P being 80° to 90°, which is not limited here.

[0023] Please see Figure 3 The connector 100 includes: a housing 1, at least one terminal 2, and a fastener 3.

[0024] Please see Figure 4 The housing 1 is provided with at least one receiving structure 101. In this embodiment, there are multiple receiving structures 101, which are arranged at intervals along a third direction P. Furthermore, there are two receiving structures 101. In other embodiments, the number of receiving structures 101 may also be one, three, four, etc.

[0025] Please see Figure 5 The accommodating structure 101 includes a communicating accommodating opening 1011 and an accommodating cavity 1012. The accommodating opening 1011 extends along a first direction M, and the accommodating cavity 1012 extends along a second direction N. The housing 1 includes a connected first housing portion 11 and a second housing portion 12. The first housing portion 11 extends along the first direction M, and the second housing portion 12 extends along the second direction N. The first housing portion 11 has an accommodating opening 1011 on the side of the second housing portion 12 away from the second housing portion 12 in the second direction N, and the second housing portion 12 has an accommodating cavity 1012 inside.

[0026] Please see Figure 6 and Figure 7 In this embodiment, there are multiple terminals 2, which are arranged at intervals along a third direction P, and each terminal 2 is disposed in a corresponding manner within the receiving structure 101. Furthermore, there are two terminals 2. In other embodiments, the number of terminals 2 can be one, three, four, etc.

[0027] Please see Figures 5-7 Each terminal 2 includes a wiring portion 21, a plug-in portion 22, and a bending portion 23. The wiring portion 21 extends along a first direction M and is disposed within the receiving opening 1011, the plug-in portion 22 extends along a second direction N and is disposed within the receiving cavity 1012, and the bending portion 23 connects the wiring portion 21 and the plug-in portion 22. In this embodiment, the bending portion 23 is disposed within the receiving opening 1011; in other embodiments, the bending portion 23 may be partially disposed within the receiving opening 1011 and partially disposed within the receiving cavity 1012.

[0028] Please see Figure 7 and Figure 8The fastener 3 includes at least one fastening part 31. Each fastening part 31 is correspondingly disposed in a receiving opening 1011 of the receiving structure 101 (see [reference]). Figure 5 Within this embodiment, the fixing part 31 extends along the first direction M. There are multiple fixing parts 31, which are arranged at intervals along the third direction P. Furthermore, there are two fixing parts 31. In other embodiments, the number of fixing parts 31 can be one, three, four, etc.

[0029] Please see Figure 7 The fixing part 31 abuts against the wiring part 21 of the terminal 2 on the side away from the plug-in part 22 in the second direction N. This is achieved by providing the fixing member 3 in the receiving opening 1011 (see...). Figure 5 Inside, the fixing part 31 of the fixing member 3 abuts against the side of the wiring part 21 away from the insertion part 22 in the second direction N. This allows observation of the positional relationship between the fixing part 31 of the fixing member 3 and the first housing part 11, thereby accurately locating and identifying the position of the terminal 2, improving the accuracy of the connector 100 during insertion, and reducing the risk of connection failure. The fixing member 3 can reduce the gap between the terminal 2 and the first shield 4, effectively suppressing impedance fluctuations, reducing the risk of electromagnetic interference, and improving signal integrity. The fixing member 3 can also improve the connection reliability between the terminal 2 and the housing 1, preventing displacement during the insertion of the connector 100, and improving the mechanical stability and electrical signal transmission stability of the connector 100.

[0030] In this embodiment, in the second direction N, the surface of the fixing member 3 away from the insertion portion 22 is flush with the surface of the first housing portion 11 away from the second housing portion 12. At this time, whether the terminal 2 is accurately installed can be determined by whether the surface of the fixing member 3 away from the insertion portion 22 is flush with the surface of the first housing portion 11 away from the second housing portion 12. This allows for accurate positioning and identification of the terminal 2, improving the accuracy of the connector 100 during insertion operations and reducing the risk of connection failure.

[0031] Please see Figure 7 and Figure 8 The fixing member 3 also includes a guide portion 32 extending along the second direction N. The guide portion 32 is connected to at least one fixing portion 31 on the side near the insertion portion 22 in the first direction M. When the fixing member 3 is inserted into the receiving opening 1011, the guide portion 32 cooperates with the inner wall of the first housing portion 11 to provide a precise guiding function, reducing the installation difficulty of the fixing member 3, reducing the installation time of the fixing member 3, and improving the assembly efficiency of the fixing member 3 and the housing 1. The guide portion 32 can further reduce the gap between the terminal 2 and the first shield 4, further improving the signal integrity, mechanical stability, and electrical signal transmission stability of the connector 100.

[0032] Please see Figure 4 , Figure 8 and Figure 9 The fastener 3 also includes a connecting portion 33. The connecting portion 33 connects between any two adjacent fasteners 31. Specifically, the connecting portion 33 extends in a third direction P. The first housing portion 11 is provided with a slot 102 that cooperates with the connecting portion 33 at a position between any two adjacent receiving structures 101. By providing the slot 102 on the first housing portion 11, the slot 102 cooperates with the connecting portion 33 of the fastener 3, which can provide a precise positioning reference for the fastener 3, ensure that the position of the fastener 3 on the housing 1 is accurate, and also realize the stable installation of the fastener 3, preventing it from loosening or falling off.

[0033] Please see Figure 3 and Figure 9 The connector 100 further includes a first shield 4 and a second shield 5. The first shield 4 is disposed around the outer periphery of the first housing portion 11, and the second shield 5 is disposed around the outer periphery of the second housing portion 12 and connected to the first shield 4. The first shield 4 and the second shield 5 can reduce or eliminate the influence of external electromagnetic interference on signal transmission, which helps to protect the integrity of the signal of the connector 100 and ensure the accuracy and stability of data transmission.

[0034] Please see Figure 10 The first shielding component 4 includes a main body 41 and two branches 42. The two branches 42 are respectively connected to both ends of the main body 41 in a third direction P. Each branch 42 includes a first shielding part 421 and a second shielding part 422. The second shielding part 422 is connected to the end of the first shielding part 421 in a second direction N away from the main body 41. A bending groove 4221 is provided at the connection between the second shielding part 422 and the first shielding part 421, extending along the first direction M. After the second shielding component 5, housing 1, terminal 2, and fixing component 3 are installed, the bending groove 4221 at the connection between the first shielding part 421 and the second shielding part 422 facilitates bending the second shielding part 422 to cover the housing 1 and the fixing component 3.

[0035] Please see Figure 10 Each branch 42 further includes a third shielding part 423. The third shielding part 423 is connected to one end of the first shielding part 421 in the first direction M, and the third shielding parts 423 of the two branches 42 are arranged facing each other along the third direction P. One branch 42's third shielding part 423 is provided with a first engaging part 4231, and the other branch 42's third shielding part 423 is provided with a second engaging part 4232 that engages with the first engaging part 4231. By engaging the first engaging part 4231 and the second engaging part 4232, the third shielding parts 423 of the two branches 42 can be pre-positioned, facilitating subsequent welding of the third shielding parts 423 of the two branches 42.

[0036] Please see Figure 3 and Figure 9 The connector 100 further includes a limiting part 6 and a supporting part 7. The limiting part 6 is disposed on the second shield 5 and extends outward from the edge of the second shield 5, and the supporting part 7 is disposed on the first shield 4 and is used to support the limiting part 6. When assembling the first shield 4 and the second shield 5, the limiting part 6 and the supporting part 7 cooperate with each other, and the supporting part 7 supports the limiting part 6 to achieve pre-positioning between the first shield 4 and the second shield 5, which facilitates subsequent welding of the first shield 4 and the second shield 5.

[0037] The limiting part 6 and the second shielding part 5 are integrally stamped. The stamping process for integrally forming the limiting part 6 and the second shielding part 5 has advantages over the drawing process, such as simple process, short process time, and suitability for mass production.

[0038] The support part 7 and the first shielding part 4 are integrally stamped. The stamping process for integrally forming the support part 7 and the first shielding part 4 has advantages over the drawing process, such as simple process, short process time, and suitability for mass production.
