Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a through-hole connector. Background Technology

[0002] Some via connectors use a shielding method that involves installing shielding rings on the shielded cable. This means that inner and outer shielding rings are installed on the shielded cable, and then the shielding layer of the shielded cable is electrically connected to the inner and outer shielding rings. The outer shielding ring is electrically connected to the metal mounting interface, thus achieving electrical connection between the shielding layer of the shielded cable and the metal mounting interface, thereby meeting electromagnetic shielding requirements.

[0003] However, the above-mentioned electrical connection method between the outer shielding ring and the mounting interface usually requires the corresponding via to be set on the mounting interface. The outer shielding ring is electrically connected to the end or inner wall of the via. However, when there are many shielded cables and the spacing is small, the mounting interface is set with vias that allow all shielded cables to pass through. In this case, it is not easy for the outer shielding ring to form an effective electrical connection with the via. Utility Model Content

[0004] This invention provides a through-hole connector to solve the problem that the shielding ring is not easy to form an effective electrical connection with the through-hole.

[0005] This utility model provides a through-hole connector, which is set on the installation interface and includes a housing and a shielded cable installed in the housing. The installation interface is provided with a through hole for the shielded cable to pass through. A first shielding element is installed on the shielded cable. A second shielding element is provided on the housing between the first shielding element and the installation interface. The first shielding element, the second shielding element and the installation interface are electrically connected in sequence.

[0006] Optionally, the gap between the via and the shielded cable is blocked axially by the first shield and the second shield.

[0007] Optionally, the first shielding component includes an outer shielding ring and an inner shielding ring at least partially inserted within the outer shielding ring. The shielding layer of the shielded cable is sandwiched between the inner shielding ring and the outer shielding ring, and the end of the outer shielding ring facing the second shielding component is electrically connected to the second shielding component.

[0008] Optionally, the second shielding element is a plate-like structure with through holes.

[0009] Optionally, the second shield has a periphery with a conductive structure that is electrically connected to the mounting interface.

[0010] Optionally, the side of the second shield facing the first shield has a transition part at the through hole, and the end of the outer shield facing the second shield is electrically connected to the transition part.

[0011] Optionally, the adapter is a cylindrical structure, with the end of the outer shielding ring facing the second shielding member inserted on the outside of the adapter and electrically connected to the adapter.

[0012] Optionally, the end of the outer shielding ring facing the adapter is provided with a plurality of contact claws along the circumferential direction, and the contact claws are provided with contacts, which are electrically connected to the outside of the adapter.

[0013] Optionally, the second shielding member is detachably installed onto the housing from the side of the housing facing the mounting interface, and the first shielding member is installed into the housing from the side of the housing away from the mounting interface and then electrically connected to the second shielding member.

[0014] Optionally, the second shielding member is detachably installed into the housing from the side of the housing away from the installation interface, and the first shielding member is electrically connected to the second shielding member after being installed into the housing from the side of the housing away from the installation interface.

[0015] This solution has at least the following beneficial effects:

[0016] In this solution, the first shield can be smoothly connected to the installation interface through the transition of the second shield, ensuring effective electromagnetic shielding. The second shield can also block the gaps between the shielded cables, further preventing electromagnetic leakage and improving shielding performance. At the same time, the second shield is located between the first shield and the installation interface. After the shielded cable and the first shield are assembled, they can be installed into the housing from one matching direction, which facilitates the assembly of the through-hole connector.

[0035] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0036] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0037] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0038] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0039] like Figure 1-11 As shown, an embodiment of the present invention provides a through-hole connector, which is disposed on the mounting interface 1, including a housing 2 and a shielded cable 21 inserted inside the housing 2. The mounting interface 1 is provided with a through-hole 11 for the shielded cable 21 to pass through. A first shielding element 3 is inserted through the shielded cable 21. A second shielding element 4 is provided on the housing 2 between the first shielding element 3 and the mounting interface 1. The first shielding element 3, the second shielding element 4 and the mounting interface 1 are electrically connected in sequence.

[0040] In this solution, the first shield 3 can be smoothly connected to the mounting interface 1 through the transition of the second shield 4, ensuring effective electromagnetic shielding. At the same time, the second shield 4 is located between the first shield 3 and the mounting interface 1. After the shielded cable 21 and the first shield 3 are assembled, they can be installed into the housing 2 from one matching direction, which facilitates the assembly of the through-hole connector.

[0041] Furthermore, to improve the shielding effect and prevent electromagnetic leakage from occurring in the gap between the shielded cable 21 and the via 11, the gap between the via 11 and the shielded cable 21 is axially blocked by the first shielding element 3 and the second shielding element 4. It should be understood that when there are two or more shielded cables 21, the gap between the via 11 and the shielded cable 21 also includes the gap between the shielded cables 21 themselves, thus meeting the requirement of improving the shielding effect. Figure 1-3 As shown in the figure, this embodiment illustrates the structure of a through-hole connector for four shielded cables 21.

[0042] To accommodate more mature processing technology, the first shielding component 3 in this embodiment includes an outer shielding ring 31 and an inner shielding ring 32 that is at least partially inserted inside the outer shielding ring 31. The shielding layer of the shielded cable 21 is sandwiched between the inner shielding ring 32 and the outer shielding ring 31. The end of the outer shielding ring 31 facing the second shielding component 4 is electrically connected to the second shielding component 4.

[0043] More specifically, such as Figure 5 , 6 As shown in Figures 8 and 11, in this embodiment, one end of the inner shielding ring 32 is located outside the outer shielding ring 31 and has a flange 321. The flange 321 is provided with a slot 322. Correspondingly, the housing 2 is provided with a block 28. After the through-hole connector is assembled, the slot 322 and the block 28 are engaged and anti-rotation in the circumferential direction, thereby preventing the shielded cable 21 from rotating.

[0044] Furthermore, in order to make the structure of the second shielding component 4 as simple as possible, making it easier to manufacture, and to provide sufficient shielding performance, such as... Figure 6 , 9 As shown in Figures 1 and 10, in this embodiment, the second shielding member 4 is a plate-shaped structure with through holes 45.

[0045] Furthermore, in order to ensure good conductive contact between the second shielding component 4 and the mounting interface 1, such as Figure 6 , 9 As shown in Figures 1 and 10, in this embodiment, the second shield 4 has an edge 41 on its periphery, and a conductive structure electrically connected to the mounting interface 1 is provided on the edge 41.

[0046] In this embodiment, the conductive structure on the edge 41 is a convex hull structure 42. The top of the convex hull structure 42 makes conductive contact with the area of ​​the mounting interface 1 around the via 11, thereby achieving electrical connection between the second shield 4 and the mounting interface 1. Of course, in other embodiments, the conductive structure can also be a spring-loaded structure or other common conductive contact structures in the art.

[0047] Furthermore, in order to ensure a convenient and stable electrical connection between the outer shielding ring 31 and the second shield during the assembly of the through-hole connector, such as Figure 6 , 9 As shown in Figure 10, in this embodiment, the side of the second shielding member 4 facing the first shielding member 3 is provided with a transition part 43 at the through hole 45, and the end of the shielding outer ring 31 facing the second shielding member 4 is electrically connected to the transition part 43.

[0048] More specifically, to fit the cylindrical shielding outer ring 31, the adapter 43 has a cylindrical structure. The end of the shielding outer ring 31 facing the second shielding member 4 is inserted into the outside of the adapter 43 and electrically connected to the adapter 43. The adapter 43 can be integrally formed with the second shielding member 4, or it can be formed separately and fixed to the second shielding member 4 by means such as welding. In this embodiment, the adapter 43 is integrally formed with the second shielding member 4.

[0049] More specifically, to further improve the contact performance between the shielding outer ring 31 and the adapter 43, the end of the shielding outer ring 31 facing the adapter 43 is provided with a plurality of contact claws 311 along the circumferential direction. The contact claws 311 are provided with contacts 312, and the contacts 312 are electrically connected to the outside of the adapter 43. The number of contact claws 311 and contacts 312 can be flexibly set according to actual needs, and the shielding outer ring 31, contact claws 311 and contacts 312 are integrally formed.

[0050] In this embodiment, a sealing ring 26 is provided on the side of the housing 2 facing the installation interface 1. The second shielding member 4 is detachably installed on the housing 2 from the side of the housing 2 facing the installation interface 1. Specifically, a buckle 44 can be provided on the second shielding member 4, and a locking platform 27 can be provided on the housing 2. The buckle 44 and the locking platform 27 are engaged to meet the detachment requirement. The first shielding member 3 is installed into the housing 2 from the side of the housing 2 away from the installation interface 1 and then electrically connected to the second shielding member 4. That is, after the second shielding member 4 is installed on the side of the housing 2 facing the installation interface 1, the shielded cable 21 and the tail cover 25, the sealing body 24, the wire clamp 23, the first shielding member 3 and other structures are assembled to form an assembly. Then, the assembly is installed into the housing 2 from the side of the housing 2 away from the installation interface 1 to complete the initial assembly of the through-hole connector. This assembly method has the advantages of saving time and effort and being convenient and quick. After the initial assembly of the through-hole connector, the matching power terminal 22 is pressed onto the end of the shielded cable 21, and then the through-hole connector is fixed at the through-hole 11 of the mounting panel to complete the final assembly.

[0051] In other embodiments, the second shielding member can be detachably installed into the housing from the side of the housing away from the mounting interface via a snap-fit ​​structure or the like. The second shielding member is then electrically connected to the mounting interface or the inner wall of the through hole via a spring-loaded structure or the like. The first shielding member is then installed into the housing from the side of the housing away from the mounting interface and electrically connected to the second shielding member.
