Description

Technical Field

[0001] This application relates to the field of electrical connectors, and in particular to an electrical connector female socket. Background Technology

[0002] In the field of electronic device connectivity, electrical connectors are crucial components for the transmission of electrical energy and signals, and their stability and reliability are paramount. Electrical connectors typically consist of a female connector and a male connector, with circuitry achieved through the insertion of the male connector into the slot of the female connector. To ensure a secure connection, especially in environments subject to vibration or external interference, the female connector is usually equipped with a self-locking device to lock the male connector inside the slot and prevent accidental dislodgement.

[0003] Traditional female connector self-locking designs typically employ a back cover integrated with the main body. The locking mechanism is activated by rotating or pushing / pulling the back cover, locking and unlocking the male connector. However, with the miniaturization and weight reduction of electronic devices, especially in specific applications such as high-frequency, high-speed signal transmission and aerospace electronic systems, higher demands are placed on the size, weight, and electromagnetic shielding performance of electrical connectors. In these scenarios, the upper structure needs to be fully shielded with a metal shell to effectively suppress electromagnetic interference and ensure signal transmission integrity and system stability.

[0004] The design of a metal-shell shield poses challenges to the overall structure of electrical connectors, especially the layout and implementation of the self-locking mechanism. Traditional self-locking unlocking methods, where the back cover is integrated with the body, often require additional operating space, making them unsuitable for ultra-thin designs. Furthermore, the assembly gap between the back cover and the body can affect the electromagnetic shielding effect, increasing the risk of electromagnetic interference. Utility Model Content

[0005] The purpose of this application is to provide a self-locking device for an electrical connector female that can meet the ultra-thin size limit while ensuring good electromagnetic shielding performance.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A female electrical connector includes a female connector body and self-locking devices respectively disposed on both sides of the female connector body. The self-locking devices are used to lock the male electrical connector inserted into the slot of the female connector body. The self-locking devices include a latching part, an unlocking pressure plate, and a mounting part. One side of the unlocking pressure plate is mounted on the female connector body through the mounting part. The unlocking pressure plate is horizontally disposed. The latching part includes a first vertical part and a first horizontal part. The first horizontal part extends from one side of the unlocking pressure plate toward the female connector body. The first vertical part extends vertically downward from one side of the first horizontal part and is inserted into the slot of the female connector body. When unlocking, pressing the unlocking pressure plate downward causes the first vertical part of the latching part to lift upward.

[0008] In one embodiment, a support limiting part is provided on the side of the unlocking pressure plate away from the female body, and the support limiting part supports the unlocking pressure plate.

[0009] In one embodiment, the support limiting portion includes a third vertical portion, a first inclined portion, and a second inclined portion. The third vertical portion extends vertically downward from one side of the unlocking pressure plate, the first inclined portion extends inclined downward from the lower end of the third vertical portion, and the second inclined portion extends inclined upward from the lower end of the first inclined portion. A fulcrum is formed between the first inclined portion and the second inclined portion.

[0010] In one embodiment, the mounting portion extends rearward from one side of the unlocking pressure plate, and the mounting portion includes a second horizontal portion and a second vertical portion. The second horizontal portion extends horizontally from one side of the unlocking pressure plate, and the second vertical portion extends downward from one side of the second horizontal portion. The second horizontal portion is mounted on the female body.

[0011] In one embodiment, a welded portion is provided horizontally extending from the lower side of the second vertical portion.

[0012] In one embodiment, a limiting part is provided on one side of the second vertical part, and the second vertical part is mounted on the female body through the limiting part.

[0013] In one embodiment, the first vertical portion has an inclined guide surface on the side corresponding to the male connector of the electrical connector.

[0014] The beneficial effects of this application are as follows:

[0015] (1) The electrical connector female socket of this application has a cleverly designed self-locking device, which makes the unlocking pressure plate horizontally set on both sides of the female socket body, and the latching part is connected to the unlocking pressure plate through the first vertical part and the first horizontal part and inserted into the slot. This layout greatly saves vertical space, meets the requirements of ultra-thin design, and enables the electrical connector female socket to be used in high-end electronic devices with limited space.

[0016] (2) Since the upper layer is entirely shielded by a metal shell, the self-locking device and its unlocking mechanism in this application are cleverly integrated on both sides of the metal shell, avoiding the risk of electromagnetic interference. In particular, the design of the unlocking pressure plate and the buckle part not only realizes the locking and unlocking functions, but also does not damage the integrity of the metal shell, thereby ensuring excellent electromagnetic shielding performance.

[0017] (3) When unlocking, the user only needs to press down on the unlocking plate to lift the first vertical part of the buckle upwards, thus unlocking the device. This operation method is intuitive and simple, requiring no additional tools or complicated actions, which significantly improves the user experience. Attached Figure Description

[0036] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0037] like Figure 1 The diagram shown is a structural schematic of the electrical connector male head and electrical connector female head after they are mated together.

[0038] like Figure 2 The diagram shows the structure of the male connector and the female connector before they are mated, as well as an enlarged view of the slot of the male connector.

[0039] like Figure 3 As shown, the present invention provides an electrical connector female socket A that is mounted on a PCB board, such as... Figure 4 and Figure 5 As shown, the female connector A mainly includes a female connector body 1 and self-locking devices 2 respectively disposed on both sides of the female connector body 1. The female connector body 1 has a slot 11 inside for receiving and fixing the male connector B.

[0040] like Figure 1 and Figure 2 As shown, the self-locking device 2 is used to lock the male connector B of the electrical connector inserted into the slot 11 of the female connector body 1, preventing it from accidentally falling out. Figure 6 As shown, the self-locking device 2 includes a latching part 21, an unlocking pressure plate 22, and a mounting part 23.

[0041] like Figure 5 and 6As shown, one side of the unlocking pressure plate 22 is mounted on the female body 1 via the mounting part 23. The unlocking pressure plate 22 is horizontally positioned for easy user operation. The mounting part 23 can securely mount the unlocking pressure plate 22 onto the female body 1 using a snap-fit ​​or other fixing method.

[0042] like Figure 6 As shown, the latching part 21 includes a first vertical part 221 and a first horizontal part 222. The first horizontal part 222 extends from one side of the unlocking pressure plate 22 toward the female body 1, forming a certain connection length to ensure the stability and strength of the latching part 21. The first vertical part 221 extends vertically downward from one side of the first horizontal part 222 and inserts into the slot 11 of the female body 1 to lock the male connector B of the electrical connector inserted into the slot 11.

[0043] like Figures 7 to 10 As shown, during the unlocking process, the user only needs to press down on the unlocking plate 22. After the unlocking plate 22 is subjected to downward pressure, a certain mechanical linkage causes the first vertical part 221 of the latching part 21 to lift upward and leave the slot B1 of the male connector B, thereby releasing the lock on the male connector B and allowing it to be pulled out of the slot 11. This application, through the design of the self-locking device 2, especially the first vertical part 221 of the latching part 21, can firmly lock the male connector B inserted into the slot 11, effectively preventing accidental dislodgement caused by external factors such as vibration and impact, thereby improving the stability and reliability of the connection.

[0044] The electrical connector female A of this application achieves the combination of the horizontally set unlocking pressure plate 22 and the buckle part 21 through the ingeniously designed self-locking device 2. This not only saves vertical space and meets the requirements of ultra-thin design, but also cleverly integrates it on both sides of the metal shell to avoid electromagnetic interference. At the same time, its intuitive unlocking operation only requires a simple press of the unlocking pressure plate 22 without additional tools, which greatly improves the user experience and is suitable for high-end electronic devices with limited space.

[0045] like Figure 6 As shown, in one embodiment, a support limiting part 24 is provided on the side of the unlocking pressure plate 22 away from the female body 1, and the support limiting part 24 supports the unlocking pressure plate 22. This ensures that the unlocking pressure plate 22 can move stably when pressed and prevents excessive deformation.

[0046] like Figure 6As shown, the specific structure of the support limiting part 24 has been further optimized. The support limiting part 24 includes a third vertical part 241, a first inclined part 242, and a second inclined part 243. The third vertical part 241 extends vertically downward from one side of the unlocking pressure plate 22, providing stable vertical support for the entire support limiting part 24. The first inclined part 242 extends downward at an angle from the lower end of the third vertical part 241, forming a gradually transitioning slope. The second inclined part 243 extends upward at an angle from the lower end of the first inclined part 242, forming a fulcrum 244 between it and the first inclined part 242. This fulcrum 244 plays a crucial role in the unlocking process, effectively transmitting the pressing force and allowing the latching part 21 to unlock smoothly.

[0047] like Figure 6 As shown, in one embodiment, the mounting portion 23 extends rearward from one side of the unlocking pressure plate 22 and includes a second horizontal portion 231 and a second vertical portion 232. The second horizontal portion 231 extends horizontally from one side of the unlocking pressure plate 22, providing a stable mounting platform. The second vertical portion 232 extends downward from one side of the second horizontal portion 231 for securely mounting the unlocking pressure plate 22 and the entire self-locking device 2 onto the female body 1.

[0048] like Figure 6 As shown, in one embodiment, a welding portion 233 extends horizontally from the lower side of the second vertical portion 232. The welding portion 233 can be welded to the PCB board 3, thereby providing additional fixing force to ensure that the self-locking device 2 will not loosen or fall off during use. In addition, the main purpose of this design is to achieve the grounding function, ensuring that the electrical connector female A can be stably and reliably connected to the grounding system during operation.

[0049] like Figure 6 As shown, in one embodiment, a limiting part 234 is provided on one side of the second vertical part 232, and the second vertical part 232 is mounted on the female body 1 through the limiting part. This limiting part 234 can cooperate with the corresponding structure on the female body 1 to achieve precise positioning and installation of the self-locking device 2. In this way, it can be ensured that the self-locking device 2 can be quickly and accurately positioned during installation and remain stable during use.

[0050] like Figure 6 As shown, in one embodiment, the first vertical portion 221 has an inclined guide surface 223 on the side corresponding to the male connector B. This facilitates the smooth insertion of the male connector and guides the latching portion 21 into place, improving the convenience and efficiency of the connection.
