[0035] This application discloses a female connector with a double-clamping structure. The female connector is designed for use in connector assembly C and is suitable for signal or power transmission in electronic devices. Since the female connector 1 is an important component of connector assembly C, the basic architecture of connector assembly C is described below to explain its structure and function. Please refer to [reference needed]. Figure 1A and Figure 1B As shown, the connector group C includes at least the female connector 1 and a male connector 2. The female connector 1 can be connected to one transmission carrier, and the male connector 2 can be connected to another transmission carrier. When the female connector 1 and the male connector 2 are plugged into each other, power and / or signal transmission between the two transmission carriers can be realized. Furthermore, depending on product requirements, the two transmission carriers can be of the same or different types, and can be circuit boards P or transmission lines L, etc. To avoid overly complex diagrams, only the components and lines mentioned later are shown on circuit board P; they are explained here first.

[0036] The structure and features of the female connector 1 will be described in detail below. In one embodiment, please refer to... Figure 2 and Figure 3As shown, the female connector 1 includes a female insulating body 11 and a female metal housing 13. The female connector 1 can be mated with a male connector. Depending on the product requirements, the female connector 1 can be mounted on a circuit board P as a board-end connector, but this is not a limitation. Furthermore, for ease of explanation of component features and relative positional relationships, the spatial form of the component is defined in the following description based on three mutually orthogonal axes: the horizontal axis (X-axis), the vertical axis (Y-axis), and the vertical axis (Z-axis). Specifically, the horizontal axis (X-axis) refers to the left-right extension direction. Figure 2 The upper left corner is used as the left side direction of the component. Figure 2 The lower right of the axis is defined as the right side of the component; the vertical axis (Y-axis) refers to the forward and backward extension direction, where... Figure 2 The lower left corner serves as the front direction of the component. Figure 2 The upper right of the axis is considered the rear direction of the component; the vertical axis (Z-axis) refers to the vertical extension direction. Figure 2 The area above is considered the top (top) side of the component. Figure 2 The area below is used as the bottom (bottom) side direction of the component.

[0037] In the described embodiments, please refer again. Figure 2 and Figure 3 As shown, the female end insulating body 11 has two first body sidewalls 111 and two second body sidewalls 112. Multiple first body sidewalls 111 and second body sidewalls 112 are spaced apart and connected to form a frame structure. In other words, the two ends of the first body sidewall 111 are respectively connected to the second body sidewall 112, and conversely, the two ends of the second body sidewall 112 are respectively connected to the first body sidewall 111. Therefore, in the three-dimensional structure of the female end insulating body 11, the two first body sidewalls 111 are opposite to each other, and the two second body sidewalls 112 are also opposite to each other, and together they can form a mating space 110. Furthermore, the mating space 110 is used to accommodate the mating portion of the male end connector 2, so that the female end connector 1 can be mated with the male end connector 2 (e.g., ...). Figure 1A As shown, they are stably interlocked. It should be noted that the specific shape and number of the mating spaces 110 can be adjusted according to the mating portion of the male connector 2 to be matched. The aforementioned mating portion refers to all components extending into the mating space 110, for example, Figure 1BThe mating portion includes multiple metal grounding cylinders 23, and each of the metal grounding cylinders 23 is provided with one or more connecting terminals 22 (but not limited thereto). In other words, the inner surfaces of the first body sidewall 111 and the second body sidewall 112 used to form the mating space 110 are not limited to the representation shown in the drawings, but can be provided with various types of structural features, such as protrusions, grooves, guide grooves, ribs or other design features, to enhance the mating stability and adapt to male connectors 2 of different specifications.

[0038] Please refer to the above. Figure 2 and Figure 3 As shown, the first body sidewall 111 is provided with two first body snap-fit ​​units 1111. The first body snap-fit ​​unit 1111 is in the form of a protrusion and is positioned close to the top surface of the first body sidewall 111, but is not limited thereto. Depending on product requirements, the position of the first body snap-fit ​​unit 1111 can be arbitrarily adjusted, and its form can be an opening or other structure, and the number can be one or more. In the above embodiment, the first body snap-fit ​​unit 1111 and the first body sidewall 111 are integrally formed to reduce the complexity of the production process; however, in some embodiments, the first body snap-fit ​​unit 1111 can be an independent component and can be assembled to the first body sidewall 111 to flexibly change its specific form.

[0039] Additionally, please refer to Figure 2 and Figure 3 As shown, the female end metal shell 13 is provided with two first shell sidewalls 131 and two second shell sidewalls 132. The first shell sidewalls 131 and the second shell sidewalls 132 are connected at intervals to form a frame structure. In other words, the two ends of the first shell sidewalls 131 are respectively connected to the second shell sidewalls 132, and the two ends of the second shell sidewalls 132 are respectively connected to the first shell sidewalls 131. Therefore, in the three-dimensional structure of the female end metal shell 13, the two first shell sidewalls 131 are opposite to each other, and the two second shell sidewalls 132 are also opposite to each other, and can together surround to form an installation space 130. The installation space 130 is vertically connected to form an open shape. Furthermore, in the aforementioned embodiment, the first shell sidewall 131 is provided with two first shell snap-fit ​​units 1311, and the second shell sidewall 132 is provided with one second shell snap-fit ​​unit 1322. However, this is not a limitation; in other embodiments of this application, the number of the first shell snap-fit ​​unit 1311 and / or the second shell snap-fit ​​unit 1322 may be one or more. Additionally, depending on product requirements, the first shell snap-fit ​​unit 1311 and / or the second shell snap-fit ​​unit 1322 may be integrally formed on the female end metal shell 13, or may be assembled to the female end metal shell 13 as independent components.

[0040] Please refer to the following: Figure 2 and Figure 3 As shown, when the female end insulating body 11 is installed into the installation space 130 of the female end metal housing 13, each first body sidewall 111 corresponds to each first housing sidewall 131, and each second body sidewall 112 corresponds to each second housing sidewall 132. To ensure stable installation of both the female end insulating body 11 and the female end metal housing 13, the first body snap-fit ​​unit 1111 is assembled and fixed with the corresponding first housing snap-fit ​​unit 1311. In this embodiment, the first housing snap-fit ​​unit 1311 is open, allowing the protruding first body snap-fit ​​unit 1111 to be inserted, thus integrating the female end insulating body 11 and the female end metal housing 13. However, this is not a limitation; any mating snap-fit ​​unit 1111 and the first housing snap-fit ​​unit 1311 are acceptable. Furthermore, since the female connector 1 has a first body snap-fit ​​unit 1111 and a first housing snap-fit ​​unit 1311 that can be joined on both opposite sides, the assembly stability of the female insulating body 11 and the female metal housing 13 can be effectively improved.

[0041] Please refer to the above. Figures 1A to 3 As shown, to ensure a stable connection between the female connector 1 and the male connector 2, the second housing latching unit 1322 is used to engage with the male latching portion 213 of the male connector 2. In this embodiment, the second housing latching unit 1322 is a through-hole and integrally formed on the second housing sidewall 132, but this is not a limitation. In other embodiments of this application, the second housing latching unit 1322 may be a protrusion or other structure, as long as it can match and engage with the male latching portion 213. Furthermore, to improve the smoothness of the aforementioned engagement process, the second body sidewall 112 may be provided with a clearance area G relative to the second housing sidewall 132. The clearance area G is used to allow the male latching portion 213 to pass through. Thus, when the male latching portion 213 of the male connector 2 engages with the second housing latching unit 1322, it will not be blocked by any component of the female connector 1. Depending on product requirements, the clearance area G includes, but is not limited to, the following different structural forms:

[0042] (1) In the first structural form, please refer to Figure 2 , Figure 4 and Figure 5AAs shown, the outer surface of the second body sidewall 112 is substantially abutting the inner surface of the second shell sidewall 132 (a gap may exist between them due to tolerance issues), and the second shell snap-fit ​​unit 1322 is in the form of a through opening (but not limited thereto). Furthermore, the top surface of the second body sidewall 112 is recessed downwards to form a recessed portion, which serves as a clearance area G and corresponds to at least a portion of the second shell snap-fit ​​unit 1322. Thus, when the male connector 2 (such as...) Figure 1A and Figure 1B When the male end of the connector 213 (as shown) is inserted into the female connector 1, its male end latching part 213 (e.g., a protrusion) can be engaged into the second housing latching unit 1322 through the recessed part (relief area G).

[0043] (2) In the second structural form, please refer to Figure 5B As shown, the top surface of the second body sidewall 112 is lower than the second housing snap-fit ​​unit 1322, so that the area above the top surface of the second body sidewall 112 can serve as a clearance area G, allowing the male connector 2 (such as...) to... Figure 1A and Figure 1B The male end latching portion 213 (e.g., a protrusion) can be engaged to the second housing latching unit 1322 through the relief area G.

[0044] (3) In the third structural form, please refer to Figure 5C As shown, the outer surface of the second body sidewall 112 is separated from the inner surface of the second shell sidewall 132 by a distance. The space between the aforementioned distances can serve as a clearance area G, allowing the male connector 2 (such as...) to... Figure 1A and Figure 1B The male end latching portion 213 (e.g., a protrusion) can be engaged to the second housing latching unit 1322 through the relief area G.

[0045] Please refer to the following: Figures 1A to 3As shown, due to the short length of the second shell sidewall 132, its deformation may be limited. Therefore, in order to make it easier for the second shell snap-fit ​​unit 1322 to engage with the male end snap-fit ​​part 213, in this embodiment, the second shell sidewall 132 is provided with two gaps 1324, and the gaps 1324 are spaced apart from each other to form an elastic sheet 1326 between the gaps 1324. The second shell snap-fit ​​unit 1322 is disposed on the elastic sheet 1326. In this way, the flexibility of the second shell snap-fit ​​unit 1322 can be effectively enhanced by the deformation capability of the elastic sheet 1326, reducing the difficulty of engagement caused by the high rigidity of the second shell sidewall 132. In addition, in this embodiment, the elastic sheet 1326 is partially inclined outward, that is, inclined in a direction away from the mounting space 130. The aforementioned inclined portion is located above the second housing latching unit 1322. The inclined design increases the passage space for the male connector 2 and effectively guides the male connector 2 to be inserted into the female connector 1, further improving the ease of insertion.

[0046] Furthermore, please refer to [the relevant documents / references]. Figures 1A to 4 As shown, in the embodiment, the top surface horizontal height H1 of the first shell sidewall 131 and the second shell sidewall 132 is higher than the top surface horizontal height H2 of the first body sidewall 111 and the second body sidewall 112. This height difference effectively expands the coverage area of ​​the male connector 2 embedded in the female connector 1, thereby providing more comprehensive protection for the male connector 2 from external impacts, dust, or electromagnetic interference. Furthermore, the higher structural support of the first shell sidewall 131 and the second shell sidewall 132 further improves the alignment accuracy and mechanical stability of the female connector 1 and the male connector 2 during insertion, reducing the risk of shaking or detachment during insertion and ensuring the stability and reliability of signal and power transmission. Simultaneously, the height difference also improves the stress distribution within the internal structure of the female connector 1, effectively extending the service life of the connector assembly C, making it suitable for various harsh operating environments.

[0047] In addition, to improve grounding efficiency, ensure low impedance of the grounding loop, reduce the impact of electromagnetic interference (EMI) and common-mode noise, and enhance the structural stability of the connector, please refer to [further details needed]. Figures 1A to 3As shown, in the embodiment described, the female connector 1 is provided with a bottom grounding metal part 12, wherein the bottom grounding metal part 12 is located at the bottom of the female insulating body 11 and can directly abut against the circuit board P to be electrically connected to the grounding line of the circuit board P, but is not limited thereto. Furthermore, the bottom grounding metal part 12 at least includes a main body portion 121, which can extend along the horizontal axis (X-axis) or the vertical axis (Y-axis). In the embodiment described, the main body portion 121 extends along the horizontal axis (X-axis) (e.g., ...). Figure 6 As shown), and its bottom horizontal height H3 is lower than the bottom horizontal height H4 of the main part of the female end insulating body 11.

[0048] For those who would like to make a special note here, please refer to [the relevant documentation]. Figures 1A to 3 As shown, the "main part" of the aforementioned female end insulating body 11 refers to the structural part directly related to the docking space 110 and its surrounding sidewalls. In other words, the main part is equivalent to the core area that carries the docking space 110, and does not include the part used for fixing to the circuit board P (e.g., Figure 1B The female end insulating body 11 has an auxiliary structure or other extended design (as shown). Specifically, the second body sidewall 112 of the female end insulating body 11 is provided with at least one limiting block 115 and a positioning post 116. In the embodiment, the limiting block 115 is located on the outer surface near the bottom of the second body sidewall 112, and the positioning post 116 extends downward from its bottom surface (but is not limited thereto). When the female end insulating body 11 is assembled to the female end metal housing 13 from bottom to top, the limiting block 115 can limit the position by contacting the female end metal housing 13, thereby keeping the female end insulating body 11 in a predetermined assembly position. At the same time, the positioning post 116 can further fix the female end insulating body 11 to the circuit board P. Furthermore, the aforementioned limiting block 115 can be regarded as an extension design of the female end insulating body 11, and the aforementioned positioning post 116 can be regarded as an auxiliary structure fixed to the circuit board P. Therefore, neither of them belongs to the "main part" of the female end insulating body 11.

[0049] Furthermore, depending on product or production requirements, the bottom grounding metal component 12 can be connected and positioned to the female end insulating body 11, or connected and positioned to the female end metal housing 13. For more details, please refer to [link / reference needed]. Figure 3 , Figures 6 to 7 As shown, in the embodiment, the bottom grounding metal component 12 is connected and positioned to the female end insulating body 11. A main beam component 113 is provided near the bottom of the female end insulating body 11, and the main beam component 113 extends along the horizontal axis (X-axis) (e.g., ...). Figure 6As shown in the figure, but not limited thereto, in other embodiments of this application, the main beam 113 may also extend along the longitudinal axis (Y-axis). Furthermore, the bottom surface of the main beam 113 can be tightly fitted with the top surface of the main body 121, and at least one partition 114 is provided on each of its opposite sides, and the partition 114 is substantially orthogonal to the main beam 113, used to divide the area near the bottom of the docking space 110 into multiple docking terminal areas 1100 (e.g., ...). Figure 6 (As shown). In some embodiments, when the circuit board P is provided with multiple conductive contacts P1 (such as gold fingers, but not limited thereto), each of the mating terminal areas 1100 can correspond to one or more conductive contacts P1 respectively, so as to realize the separation and positioning of each connection terminal 22 of the male connector 2, so that each connection terminal 22 can accurately abut against each of the conductive contacts P1.

[0050] Following on, please refer to Figure 3 and Figures 7 to 9 As shown, at least one clamping part 123 is provided on each of the opposite sides of the main body 121. Each clamping part 123 can be bent upward and abut against the side of the main beam 113, thereby enabling the bottom grounding metal part 12 to be securely clamped and fixed to the main beam 113. However, the design of this application is not limited to the above clamping method. In other embodiments of this application, the bottom grounding metal part 12 can also be installed on the main beam 113 or the partition 114 by means of a snap-fit ​​or other fixing method; or, the female end insulating body 11 may not be provided with the main beam 113 and / or the partition 114, and the bottom grounding metal part 12 can be positioned to other parts of the female end insulating body 11 (such as: the first body sidewall 111 and / or the second body sidewall 112); or, the bottom grounding metal part 12 can be positioned to other parts of the female end insulating body 11 (such as: the first body sidewall 111 and / or the second body sidewall 112); or, the bottom grounding metal part 12 can be positioned to other parts of the female end insulating body 11 (such as: the first body sidewall 111 and / or the second body sidewall 112). Component 12 can be an independent assembly assembled to the female end metal housing 13; or, the bottom grounding metal component 12 can be integrally formed on the female end metal housing 13; or, the bottom grounding metal component 12 can be simultaneously connected and positioned to the female end insulating body 11 and the female end metal housing 13. For example, the bottom grounding metal component 12 can have a clamping portion 123 and can be assembled to the female end metal housing 13; thus, the assembly structure of the bottom grounding metal component 12 can be flexibly adjusted according to product or production requirements. Furthermore, in the above embodiments, the clamping portion 123 is integrally formed on the main body portion 121, but this is not a limitation. In some embodiments, the clamping portion 123 can be an independent component assembled to the main body portion 121.

[0051] Please refer again to the above embodiments. Figure 3 and Figures 7 to 9The bottom grounding metal part 12 is also provided with at least one rib 124, which is substantially orthogonal to the main body 121, and its top can be embedded in the corresponding separator 114, thus effectively enhancing the structural strength and stability of the separator 114. Furthermore, depending on product or production requirements, the rib 124 can be installed as an independent component onto the main body 121, or the rib 124 can be integrally formed onto the main body 121. In addition, to improve the connector assembly C (such as...) Figure 1A and Figure 1B To enhance electromagnetic shielding and grounding efficiency (as shown), thereby improving signal stability and preventing static electricity accumulation, the bottom grounding metal part 12 is also provided with at least one contact portion 125. The contact portion 125 can be used to abut against the grounding component of the mating male connector 2, so that the grounding components of the female connector 1 and the male connector 2 can directly contact each other, thereby forming a low-impedance grounding loop, effectively dissipating stray current, and reducing the risk of poor grounding.

[0052] Following on, please refer to Figure 3 and Figures 7 to 10 As shown, depending on product requirements, the contact portion 125 can be in the form of a protrusion and can be disposed on the clamping portion 123 and / or the rib portion 124. In the embodiment, since the rib portion 124 can serve as the sidewall of the mating terminal area 1100, it can be located between the two metal grounding cylinders 23 of the male connector 2. Therefore, at least one contact portion 125 can be provided on the opposite sides of the rib portion 124, and each contact portion 125 can abut against different metal grounding cylinders 23 (i.e., grounding components) of the male connector 2. Thus, since the bottom grounding metal part 12 is located at the bottom of the female end insulation body 11, the design complexity of the internal structure of the female end insulation body 11 can be reduced, and it can be easily connected to external grounding components or grounding lines to form an effective electromagnetic shielding structure and reduce external electromagnetic interference (EMI).

[0053] Furthermore, depending on the application requirements, if signal coupling, filtering, power isolation, high-frequency regulation, and load balancing are needed in the circuit to significantly improve signal transmission quality and circuit stability, an AC capacitor is typically placed in the adjacent circuit of the connector to handle interference and losses that may occur during AC signal transmission. In other words, AC capacitors can be used to couple high-frequency signals, achieve DC isolation, and filter out unwanted noise or high-frequency interference, thereby ensuring signal integrity and stability. Simultaneously, AC capacitors can adjust the impedance matching between input and output, prevent signal reflection, and improve transmission efficiency. In addition, in power transmission applications, AC capacitors can be used to smooth load fluctuations and prevent transient voltage fluctuations from affecting the overall circuit performance.

[0054] As stated above, in the described embodiments, please refer again to Figures 1A to 1B As shown, the female connector 1 and the circuit board P together form a connector substrate assembly. The circuit board P has multiple conductive contacts P1 and multiple AC capacitors 3, with each AC capacitor 3 electrically connected to each conductive contact P1 to provide signal coupling, filtering, or impedance matching functions. Furthermore, when the female connector 1 is fixed to the circuit board P, the multiple AC capacitors 3 can be located at the bottom of the female connector 1 within a clearance space. This clearance space refers to the space provided to accommodate the AC capacitors 3, and its design can be adjusted according to different application requirements to avoid structural interference between the AC capacitors 3 and the female connector 1 or the circuit board P. For example, as... Figure 2 and Figure 11 As shown, the vertical projection range V represented by the dashed frame is formed by the outer surfaces of the first shell sidewall 131 and the second shell sidewall 132 of the female connector 1. The AC capacitor 3, which is electrically connected to each of the conductive contacts P1, is located within the vertical projection range V at the bottom of the female connector 1. In this way, more space can be freed up on the circuit board P, making it easier to lay out other electronic components and achieve effective use of space.

[0055] Please refer to the following: Figure 1A and Figure 1B As shown, depending on the product requirements, a single conductive contact P1 can electrically connect a single AC capacitor 3 or multiple AC capacitors 3. Similarly, a single conductive contact P1 can be used to abut one or more connection terminals 22. However, in the above embodiment, the example is that a single conductive contact P1 is directly electrically connected to a single AC capacitor 3, and only one connection terminal 22 is used for abutment. This simplifies the circuit design and reduces the complexity of electrical connections. Especially in high-speed signal transmission applications, the correspondence between a single conductive contact P1 and a single AC capacitor 3 helps to improve impedance matching accuracy, further reduce signal loss and reflection, reduce the risk of potential signal interference, and ensure the stability and integrity of signal transmission.

[0056] Please refer to the above. Figure 1A , Figure 1B and Figure 11 As shown, where, Figure 11 The imaginary wireframe represents the docking terminal area 1100. In this embodiment, the position of each AC capacitor 3 corresponds to a single docking terminal area 1100. The aforementioned "correspondence" includes the following three forms:

[0057] (1) The AC capacitor 3 is located outside the range of the mating terminal area 1100, but within the spatial range of the mating terminal area 1100 along the extension direction of the horizontal axis (X-axis) or the vertical axis (Y-axis) (e.g.) Figure 11 (as shown);

[0058] (2) The entire position of the AC capacitor 3 is completely within the range of the docking terminal area 1100;

[0059] (3) The AC capacitor 3 is located at the edge of the docking terminal area 1100 and spans the inner and outer range of the docking terminal area 1100.

[0060] In other words, the location of AC capacitor 3 will not correspond to the wall between adjacent mating terminal areas 1100, in order to simplify the wiring path. Also, as... Figure 11 As shown, a single docking terminal area 1100 can correspond to two AC capacitors 3, but this is not a limitation. In other embodiments of this application, a single docking terminal area 1100 can correspond to one or more AC capacitors 3, and the number of AC capacitors 3 corresponding to each docking terminal area 1100 can be the same or different, depending on the specific application requirements, so as to provide better layout flexibility.

[0061] Furthermore, when the AC capacitor 3 is completely within the mating terminal area 1100, it may be too close to the conductive contact P1, causing difficulties in wiring and component installation; when the AC capacitor 3 is outside the area or at the edge of the mating terminal area 1100, it may be relative to the bottom of the side wall of the female connector 1. Therefore, in the above embodiment, please refer to [the relevant documentation]. Figures 1A to 4 As shown, the bottom sidewall of the female end insulating body 11 is provided with a plurality of body chambers 117, and the bottom sidewall of the female end metal shell 13 is provided with a plurality of shell chambers 137. Each body chamber 117 corresponds to each shell chamber 137, and together they form a clearance cavity 15. However, in other embodiments of this application, Figure 4 The plurality of body chambers 117 indicated herein can be connected left and right to form a single body chamber 117, and can correspond to a plurality of shell chambers 137; or, Figure 4 The multiple shell chambers 137 can be connected left and right to form a single shell chamber 137, and can correspond to multiple body chambers 117; or, a body chamber 117 can be provided only at the bottom of the side wall of the female end insulating body 11; or, a shell chamber 137 can be provided only at the bottom of the side wall of the female end metal housing 13; in other words, as long as the bottom of the female end connector 1 has at least one clearance cavity 15 for accommodating the AC capacitor 3. Furthermore, please refer to... Figure 12As shown, a single clearance cavity 15 can accommodate multiple AC capacitors 3, and the cavity wall of the clearance cavity 15 will not directly contact the AC capacitors 3. However, this is not a limitation; in other embodiments of this application, a single clearance cavity 15 can accommodate only a single AC capacitor 3. Thus, without increasing the overall height or size of the female connector 1, the AC capacitors 3 can be properly positioned within the clearance space. The aforementioned clearance space includes the cavity space in the clearance cavity 15 and the bottom space of the female connector 1 or the mating terminal area 1100, such that multiple AC capacitors 3 are all located within the vertical projection range V (e.g., ...). Figure 11 As shown, this design satisfies the requirements for a thinner and lower profile connector. It also allows for more space on the circuit board P to accommodate other electronic components, effectively ensuring the coordinated operation between the AC capacitor 3 and the female connector 1, and enhancing the design flexibility of the connector substrate assembly.
