Description

Technical Field

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

[0002] Existing socket connectors include a housing and a shielding shell. The end of the housing facing the mating plug connector has a pin. The shielding shell is inserted and fixed to the outside of the pin along the insertion direction of the plug connector and has pins that are electrically connected to the mounting interface. When there are two pins on the housing, in order to improve the shielding capability of the shielding shell, the shielding shell extends to cover the area of ​​the housing located between the two pins.

[0003] When the socket connector has a high-voltage interlock function, the socket connector housing is also provided with an interlock terminal. One end of the interlock terminal passes through the area between two adjacent plug pins of the housing, and the other end passes through the low-voltage interface preset on the end of the housing facing the plug connector. At this time, the corresponding part of the shielding shell needs to be provided with a clearance hole for the interlock terminal to pass through.

[0004] However, the presence of clearance holes on the aforementioned shielding shell may lead to electromagnetic leakage, causing a decrease in shielding performance and potentially interfering with the correct transmission of signals by the interlocking terminals. Utility Model Content

[0005] This invention provides a socket connector to solve the problem of electromagnetic leakage that may occur in existing socket connectors due to clearance holes.

[0006] This utility model provides a socket connector, comprising: a housing having at least two spaced-apart clearance holes; a core having a core inserted into each clearance hole, the core having a power terminal disposed therein; and a shielding assembly including a first shield sleeved on the outside of the core and at least one second shield disposed between different cores, the first shields sleeved on the outside of different cores being electrically connected through at least one second shield; and interlocking terminals disposed on the area of ​​the housing not covered by the shielding assembly.

[0007] Optionally, the bottoms of the different cores are connected as an integral structure by a base, and the second shield covers the top of the base and is located between the different cores.

[0008] Optionally, the first shielding body includes a body sleeved on the outside of the corresponding core and an extension extending from the bottom of the core to the adjacent core, wherein the second shielding body and the extension at least partially overlap and are electrically connected.

[0009] Optionally, the second shield is located between the extension body and the base.

[0010] Optionally, the base and the housing are detachably connected by bolts.

[0011] Optionally, the bolt structure includes a fixing bolt and a fixing nut. The fixing nut is disposed inside the housing and located between two adjacent cores. One end of the fixing bolt passes through the base and the second shield in sequence and is screwed to the fixing nut.

[0012] Optionally, the base has a positioning part protruding from one end facing the housing, and the second shield has a through hole. The positioning part and the through hole are fitted together to position the second shield. The positioning part has a through hole for the fixing bolt to pass through.

[0013] Optionally, the diameter of the other end of the fixing bolt is larger than the diameter of the through hole to shield the through hole axially.

[0014] Optionally, a protective cover is detachably connected to the base and placed on the outside of the other end of the fixing bolt.

[0015] Optionally, a retaining ring is formed on the housing, and each of the clearance holes is located inside the retaining ring. A low-pressure interface is formed on the outside of the retaining ring on the housing. One end of the interlocking terminal is disposed inside the low-pressure interface, and the other end extends to the inside of the retaining ring.

[0016] This utility model has at least the following beneficial effects:

[0017] In this design, the interlock terminals and the shielding components are set separately, meaning that the interlock terminals no longer pass through the shielding components. This avoids electromagnetic leakage caused by the shielding components having holes to avoid the interlock terminals, resulting in excellent overall shielding performance.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] like Figure 1-11 As shown, the present invention provides a socket connector, including a housing 1, a core 2, an interlocking terminal 3, and a shielding assembly 4.

[0045] Specifically, the housing 1 has two spaced-apart clearance holes 13, and each clearance hole 13 has a core 2 inserted into it. The core 2 has a power terminal 5 inside it. The shielding assembly 4 includes a first shield 41 sleeved on the outside of the core 2 and a second shield 42 disposed between different cores 2. The first shields 41 sleeved on the outside of different cores 2 are electrically connected through a second shield 42. Interlocking terminals 3 are provided on the area of ​​the housing 1 not covered by the shielding assembly 4.

[0046] Therefore, in this embodiment, the interlock terminal 3 and the shielding component 4 are set separately, that is, the interlock terminal 3 no longer passes through the shielding component 4, avoiding electromagnetic leakage caused by the shielding component 4 making a hole to avoid the interlock terminal 3, and the overall shielding performance is excellent.

[0047] Obviously, in other embodiments, the number of clearance holes can also be three or more. When the number of clearance holes is three or more, a second shield can be provided between adjacent cores. There can also be two or more second shields between adjacent cores, such as stacked in the insertion direction, to further seal any possible gaps. However, usually only one second shield is needed between adjacent cores to meet the predetermined shielding requirements.

[0048] Furthermore, to avoid potential structural interference between the shielding component 4 and the interlocking terminal 3, the area where the interlocking terminal 3 can be installed is expanded, such as... Figure 7 , 8As shown, in this embodiment, the bottoms of different cores 2 are connected into an integral structure by a base 21. The second shield 42 covers the top of the base 21 and is located between the different cores 2. That is to say, the above-mentioned integral structure including the core 2 and the base 21 needs to be installed into the housing 1 from the bottom so that the core 2 can be installed into the corresponding clearance hole 13. At this time, the second shield 42 is located between the housing 1 and the base 21. The interlocking terminal 3 and the second shield 42 actually form a layered arrangement. Thus, the installable area of ​​the interlocking terminal 3 on the housing 1 is expanded. Even if the interlocking terminal 3 is set in the area of ​​the housing 1 between the two cores 2, the second shield 42 does not need to be hollowed out to avoid it, and the shielding performance is not affected.

[0049] To maximize shielding performance and ensure good conductive contact with the second shield 42, as a further modified implementation, such as... Figure 7-11 As shown, the first shield 41 includes a body sleeved on the outside of the corresponding core 2 and an extension 43 extending from the bottom of the core 2 to the adjacent core 2. The second shield 42 and the extension 43 at least partially overlap and are electrically connected.

[0050] Based on the actual electromagnetic characteristics generated, and to avoid gaps that could lead to electromagnetic leakage between the second shield 42 and the first shield 41, as a further modified implementation, such as... Figure 7-11 As shown, the second shield 42 is located between the extension body 43 and the base 21, and the second shield 42 can actually abut against the outer wall of the core 2.

[0051] Furthermore, to facilitate the assembly and disassembly of the base 21 and the housing 1, such as... Figure 4-8 As shown, in this embodiment, the base 21 and the housing 1 are detachably connected by a bolt structure.

[0052] As an optimized implementation of the structure and operation, such as Figure 4-8 As shown, the bolt structure includes a fixing bolt 7 and a fixing nut 71. The fixing nut 71 is disposed inside the housing 1 and located between two adjacent cores 2. Specifically, the fixing nut 71 can be disposed inside the housing 1 by embedding injection molding. One end of the fixing bolt 7 passes through the base 21 and the second shield 42 in sequence and is screwed to the fixing nut 71.

[0053] To locate the second shield 42, as a further modified implementation, such as Figure 7 and Figure 9-11 As shown, a positioning part 22 is provided on the end of the base 21 facing the housing 1. A through hole 44 is provided on the second shield 42. The positioning part 22 and the through hole 44 are fitted together to position the second shield 42. A through hole is provided in the positioning part 22 for the fixing bolt 7 to pass through.

[0054] Understandably, to prevent electromagnetic leakage between the bolt and the through hole 44, based on the actual electromagnetic characteristics generated, it is necessary to block the shielding gap between the bolt and the through hole 44 in the axial direction. As a further modification, such as... Figure 4 , 11 As shown, the diameter L1 of the other end of the fixing bolt 7 is larger than the diameter L2 of the through hole 44 to shield the through hole 44 axially.

[0055] To protect the fixing bolt 7, as a further modified implementation method, such as... Figure 2 , 4 As shown in Figure 8, a protective cover 6 is detachably connected to the base 21, which is placed on the outside of the other end of the fixing bolt 7. Specifically, the protective cover 6 can be detachably connected through a conventional detachable structure such as a snap-fit ​​structure 8.

[0056] like Figure 1-6 As shown, in this embodiment, a retaining ring 11 is formed on the upper part of the housing 1, and each clearance hole 13 is located inside the retaining ring 11. A low-voltage interface 12 is formed on the outer side of the housing 1 on the retaining ring 11. One end of the interlocking terminal 3 is disposed inside the low-voltage interface 12, and the other end extends to the inner side of the retaining ring 11. Thus, the interlocking terminal 3 can be electrically connected to the corresponding signal system from inside the low-voltage interface 12 without having to extend the wire from the bottom of the housing 1 before being electrically connected to the signal system. This does not affect the shielding performance of the shielding component 4. Specifically, the interlocking terminal 3 can be disposed inside the housing 1 by embedding injection molding process.

[0057] The reference assembly process for this socket connector is as follows.

[0058] 1. Install the second shield 42 onto the top of the base 21;

[0059] 2. The first shield 41 is mounted onto the core 2 to form a combination of shielding assembly 4, core 2, and base 21;

[0060] 3. Insert the assembly from the bottom of the housing 1, so that the core 2 passes through the corresponding clearance hole 13. The housing 1 has already been embedded with an injection-molded interlocking terminal 3.

[0061] 4. Pass the fixing bolts 7 through the base 21 and the second shield 42 in sequence, and then screw them into the fixing nut 71 to complete the fixing of the assembly;

[0062] 5. Install the protective cover 6 onto the base 21;

[0063] 6. Finally, insert the power terminal 5 into the core 2.

[0064] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
