Description

TECHNICAL FIELD

[0001] The utility model relates to a socket connector, especially a socket connector with electromagnetic shielding effect. BACKGROUND

[0002] LVDS (Low Voltage Differential Signaling) is a data transmission technology widely used in high-speed data transmission. Its main feature is that it transmits differential signals through two signal lines, enabling high-speed communication with low voltage (usually between 0.3V and 0.6V), low power consumption, low noise and strong anti-electromagnetic interference capability.

[0003] The main application scenarios of LVDS include LCD display panels, notebook computers, etc. LVDS is used to transmit data and control signals, or is widely used in telecommunications, automotive electronics, industrial control and other high-speed communication fields. The advantage of LVDS is its high transmission rate (usually up to hundreds of Mbps or higher), and due to the use of differential signal transmission, it can effectively suppress noise, making it particularly suitable for high-speed, low-power applications.

[0004] However, in the environment of high-speed communication, the electromagnetic field between adjacent signal sources will interfere with each other, resulting in crosstalk, affecting the accurate transmission of data. This situation is particularly evident in dense wiring or high-speed transmission. Such electromagnetic interference may cause signal distortion or attenuation, especially at the connector and cable connection. Therefore, the high-speed communication field urgently needs an innovative connector design to effectively reduce the interference of electromagnetic effects on transmission signals, thereby ensuring the stability and accuracy of data transmission.

[0125] Embodiments of the connector assembly will be described below with reference to the accompanying drawings, in which like elements or elements having like functions are denoted by like reference numbers throughout the figures. The figures are not drawn to scale.

[0126] Referring to Figure 1 and Figure 2 , the constituent elements of the connector assembly according to the embodiments of the present application are schematically explained, wherein Figure 1 is a perspective view of the connector assembly according to the embodiments of the present application in a mated state, Figure 2 is a perspective view of the connector assembly according to the embodiments of the present application in an unmated state. As Figure 1 shown, the connector assembly 1 is disposed on a substrate 2, which includes a receptacle connector 100 and a plug connector 200 mated with the receptacle connector 100.

[0127] Please refer to Figure 3 , which shows the combination schematic view of the receptacle connector 100 in the embodiments of the present application. The receptacle connector 100 of the present application includes an insulating housing 110, a receptacle top shell 120, a receptacle bottom shell 130, a plurality of contact pieces 140, a rotating rod 150, and a sliding upper cover 160. After the receptacle bottom shell 130 is combined with the insulating housing 110, the contact pieces 140 are assembled into the insulating housing 110, and each contact piece 140 has a terminal portion 142 extending out of an end face of the insulating housing 110, so as to facilitate subsequent welding of the assembled receptacle connector 100 to the substrate 2 for electrical connection with the substrate 2. Then, the rotating rod 150 is assembled into a receiving groove formed by the insulating housing 110 and the receptacle bottom shell 130, and the receptacle top shell 120 is covered on the insulating housing 110 and the receptacle bottom shell 130, and the rotating rod 150 is limited between the above three to enable the rotating rod 150 to rotate only around the receiving groove as the center. In addition, the receptacle top shell 120 has an extended end face 122 extending out of the end face of the insulating housing 110, for semi-openly covering the terminal portion 142 of the contact piece 140. As shown, it is obvious that the receptacle connector 100 is mainly composed of the insulating housing 110, the receptacle top shell 120, and the receptacle bottom shell 130, which are combined into a housing assembly 101, and the rotating rod 150 is pivotally arranged in the housing assembly 101 and can rotate within a certain angle around the housing assembly. Finally, the sliding upper cover 160 is embedded above the housing assembly 101 and can slide horizontally relative to the housing assembly 101 within a certain stroke, as described below.

[0128] Please refer to Figure 4 , which shows the exploded perspective view of the main components of the plug connector 200 in the embodiments of the present application. The plug connector 200 includes an insulating housing 210, a plug top shell 220, a plug bottom shell 230, a plurality of contact pieces 240, and a plurality of coaxial lines 250. As Figure 4As shown, both the insulating housing 210 assembled with the plurality of contacts 240 and the plug bottom shell 230 are molded in an insert molding manner. Subsequently, the plurality of coaxial lines 250 connected in series by a ground bar are assembled into a receiving space formed by both the insulating housing 210 and the plug bottom shell 230, so that each coaxial line 250 can be electrically connected to each contact 240. After that, a hot bar process is performed to complete the grounding of all the coaxial lines 250, and then the plug top shell 220 is embedded into the insulating housing 210 and the plug bottom shell 230 to complete the assembly process of the plug-type connector 200. It should be noted that each contact 240 of the plug-type connector 200 also has a terminal portion 242. After the subsequent mating and pairing of the plug-type connector 200 and the plug-type connector 200, the terminal portion 242 of the plug-type connector 200 will physically contact the contact 140 of the plug-type connector 100, and the plug-type connector and the plug-type connector will be electrically connected for signal transmission.

[0129] Please refer to the following Figure 5A and Figure 5B wherein, Figure 5A shows a schematic diagram of the mating and pairing process of the plug-type connector 200 and the plug-type connector 100 in an embodiment of the present application. Figure 5B shows a schematic diagram of the state before the mating and pairing of the two. Specifically, the sliding upper cover 160 has two front edge portions 162 arranged at the front edge of the sliding upper cover 160. In contrast, the sliding upper cover also has a covering portion 164 arranged at the rear edge of the sliding upper cover 160. In the preferred embodiment, the plug top shell 220 of the plug-type connector 200 has two recessed portions 222, which can correspond to the two front edge portions 162 of the sliding upper cover 160 when the plug-type connector 200 and the plug-type connector 200 are mated and paired. It should be particularly noted that before the plug-type connector 200 is inserted into the plug-type connector 100, the sliding upper cover 160 of the plug-type connector 100 is relative to the housing assembly 101 in a pairing starting position, as shown in the dashed line of step (b) in Figure 5A the mating and pairing process of the two. In this pairing starting position, the covering portion 164 of the sliding upper cover 160 is in an unclosed state, that is, it has not covered the terminal portions 142 of all the contacts 140 of the plug-type connector 100, and the purpose is to expose the terminal portions 142 to the outside, so as to facilitate the visual optical detection of the terminal portions 142 by the automated optical inspection (AOI) equipment to confirm the surface tin paste condition of the terminal portions 142. After the detection is correct, the mating and pairing process between the two connectors is performed.

[0130] Please refer to the following Figure 5A and Figure 5BWhen the plug-type connector 200 is inserted into the socket-type connector 100, the two recessed portions 222 of the plug top housing 220 of the plug-type connector 200 will push the two front edge portions 162 of the sliding upper cover 160 of the socket-type connector 100 respectively, so that the sliding upper cover 160 slides horizontally relative to the housing assembly 101 and slides to a mating completion position. At the mating completion position, as shown by the state of the dashed line in step (c) of Figure 5A , the cover portion 164 of the sliding upper cover 160 can enter a closed state, and the extended end face 122 of the socket top housing 120 completely covers the terminal portions 142 of all the contact elements 140 of the socket-type connector 100 to form an electromagnetic shielding effect, which provides complete electromagnetic protection for signal transmission, as shown by the state of the dashed line in step (d) of Figure 5C .

[0131] One feature of the connector assembly 1 of the utility model is that the connector assembly 1 has a locking function, which is used to ensure that after the plug-type connector 200 is completely embedded with the socket-type connector 100, the plug-type connector 200 will not be unexpectedly separated from the socket-type connector 100 due to changes in the use environment, for example, the conventional vehicle connector is easily affected by vibration when the vehicle is running, which causes poor contact between the connectors. Specifically, after the plug-type connector 200 is completely embedded with the socket-type connector 100, the rotating rod 150 on the socket-type connector 100 can be rotated, so that the rotating rod 150 is rotated from a first position adjacent to the extended end face 122 of the socket top housing 120 to a second position adjacent to the coaxial line 250 of the plug-type connector 200, as shown by the process from step (c) to step (d) of Figure 5A . When the rotating rod 150 is in the second position, the rotating rod 150 can be limited by a mortise 224 on one side of the plug top housing 220 of the plug-type connector 200 to form a locked state, as shown by the state of the dashed line in step (d) of Figure 5D , which prevents the plug-type connector 200 from being separated from the socket-type connector 100, ensures that the two connectors can be properly connected under the changes of the harsh environment, and guarantees the signal transmission quality. It should be noted that when the rotating rod 150 is reversely rotated from the second position back to the first position, the rotating rod 150 is reversely unlocked from the mortise 224, and then the user can completely separate the plug-type connector 200 from the socket-type connector 100.

[0132] The following will describe in detail how the sliding upper cover of the socket-type connector completely covers the terminal portions of the contact elements and forms an electromagnetic shielding effect by means of the pushing of the plug-type connector when the plug-type connector is embedded with the socket-type connector. Please refer to Figure 7 , Figures 8A-8CThis diagram illustrates the horizontal sliding of the sliding top cover of the socket-type connector 100 between different positions on the housing assembly. It should be noted that the housing assembly 101 of the socket-type connector 100 is provided with two slide rail portions 102, and the sliding top cover 160 also has two extension arms 166 and two wings 168, respectively disposed at the front and rear positions of the two side edges of the sliding top cover 160, as shown below. Figure 7 As shown. The slide rail 102 allows the sliding top cover 160 to slide horizontally between two opposite ends (i.e., the first end 1021 and the second end 1022) inside it. Please refer to... Figure 7 As shown, the slide rail portion 102 of the housing assembly 101 is actually defined by a lower sliding groove 112 of the insulating housing 110 and an upper sliding groove 124 of the socket top housing 120. Each extension arm 166 on both sides of the sliding top cover 160 extends downward from the side edge of the sliding top cover 160 into the slide rail portion 102. Furthermore, each extension arm 166 has a limiting pin 1661 protruding from the extension arm 166, which allows it to slide horizontally between the first end 1021 and the second end 1022, restricted by the slide rail portion 102 of the housing assembly 101.

[0133] It should be noted that, as Figure 8A As shown, the slide rail portion 102 has an assembly groove 1023 at the front end of the first end 1021, so that when the sliding cover 160 is initially assembled to the housing assembly 101, the extension arms 166 on both sides of the sliding cover 160 can be inserted into the assembly groove 1023. Furthermore, in particular, the sliding groove 112 of the insulating housing 110 has a guide slope 1122, such as... Figure 8B As shown, the limiting pin 1661, which guides the sliding cover 160, moves along the guide ramp 1122 and is positioned at the first end 1021 of the slide rail 102. Figure 8B The enlarged view in the image (for easier display of the internal structure) is a partial view. Figure 8B , Figure 8C The diagram omits or hides the top shell 120 of the socket, mainly showing the partial structure of the insulating shell 110 and the sliding top cover 160. The extension arm 166 of the sliding top cover 160 has a certain space within the assembly groove 1023. During the process of the extension arm 166 moving forward to the first end 1021 (e.g....), Figures 8A-8B As indicated by the arrow, because the limiting pin 1661 is indirectly subjected to force by the guide ramp 1122, the assembly groove 1023 can still provide a certain space margin for the extension arm 166 to deform appropriately without causing damage between the contact components. After the extension arm 166 is displaced to the first end 1021, the structure of the extension arm 166 can return to its normal state due to the removal of the external force, and the structural discontinuity formed by the guide ramp 1122 restricts the extension arm 166 from sliding back into the assembly groove 1023, so that it is stably positioned at the first end 1021.

[0134] Please continue to refer to Figure 8B With Figure 8C clearly shows the process of the sliding upper cover 160 sliding on the slide rail portion 102 from the first end portion 1021 to the second end portion 1022, so that the sliding upper cover 160 can insert the exposed terminal portion 142 of the contact member into the socket connector by means of the plug connector. It should be noted that, in order to avoid the sliding upper cover 160 from jumping or mispositioning in the vertical direction during the horizontal sliding process, resulting in the terminal portion 142 not being completely covered, two vertical limit members 126 are arranged on the socket top shell 120, respectively arranged on both sides of the socket top shell adjacent to each terminal portion 142. The vertical limit member 126 is a limit member protruding from the surface of the socket top shell 120 by a certain height, and there is a certain space between the vertical limit member 126 and the upper surface of the socket top shell 120, which is sufficient to accommodate the wings 168 on both sides of the sliding upper cover 160 inside. When the sliding upper cover 160 slides horizontally from the first end portion 1021 to the second end portion 1022 of the slide rail portion 102, the vertical limit members 126 on both sides of the socket top shell can limit the wings 168 on both sides of the sliding upper cover 160 to slide horizontally inside them and not to jump out. In particular, as shown in Figure 8A , when the sliding upper cover 160 is initially assembled to the shell assembly 101, the extension arm 166 at one end of the sliding upper cover 160 has already been embedded in the assembly groove 1023, but at this time the wing 168 at the other end has not yet entered the limiting range of the vertical limit member 126. As shown in Figure 8B , when the extension arm 166 is displaced to the first end portion 1021, the wing 168 just enters the limiting range of the vertical limit member 126, and when the sliding upper cover 160 performs the entire horizontal sliding stroke from the first end portion 1021 to the second end portion 1022, as shown in Figure 8C , the wings 168 on both sides of the sliding upper cover 160 are all within the limiting range of the vertical limit member 126 throughout the entire horizontal sliding process, so as to ensure that the sliding upper cover 160 does not jump or misposition during the horizontal sliding process, and to ensure that the terminal portion is completely covered by the covering portion 164 of the sliding upper cover 160 together with the extended end surface 122 of the socket top shell 120, so as not to be disturbed by external electromagnetic noise.

[0135] Please refer to Figure 9 , which shows a schematic diagram of the socket connector in a preferred embodiment of the present application. In this embodiment, the socket top shell 120 of the socket connector 100 also has two stop members 128 arranged at the position where the upper surface of the socket top shell abuts against the front edge portion 162 of the sliding upper cover 160. In essence, the stop member 128 is a protruding portion on a recessed structure (see Figure 7The size of the recessed structure of the retreat prevention member 128 is capable of accommodating a portion of the front edge portion 162 of the sliding upper cover 160, and the protruding portion will form a bag mouth-like recess. When the sliding upper cover 160 is horizontally slid to the second end portion 1022 of the slide rail portion 102, the front edge portion 162 of the sliding upper cover 160 is partially accommodated in the recessed structure of the socket top shell due to the pushing of the plug-type connector, and is clamped by the protruding portion of the retreat prevention member 128 so as not to slide back, thereby ensuring that the front edge portion 162 will not be separated from the socket top shell, and further ensuring that the sliding upper cover 160 completely covers the terminal portion.

[0136] Please refer to Figure 10 In the preferred embodiment of the present application, the socket top shell 120 further comprises two support members 129, which are respectively arranged on the two side surfaces of the socket top shell 120, and are used to support the rotation rod 150 to be parked at the first position. In particular, when the rotation rod 150 is parked at the first position, the rotation rod 150 is positioned at a certain height from the substrate 2, so as to avoid the rotation rod 150 from contacting the substrate 2. When it is necessary to separate the plug-type connector 200 from the socket-type connector 100, a force is applied to make the rotation rod 150 disengage from the restriction of the tenon 224, and the rotation rod 150 is rotated from the second position back to the first position, so that the connector assembly 1 is in an unlocked state and can be further separated from the plug-type connector 200. At this time, the rotation rod 150 is parked on the support member 129, so as to avoid the rotation rod 150 from being excessively rotated to contact the substrate 2, thereby avoiding the rotation rod 150 from being excessively rotated to separate the fixed solder joints or terminals of the socket-type connector 100 from the substrate 2, and affecting the grounding state of the fixed solder joints of the socket-type connector 100.

[0137] Please refer to Figures 11-13The figures show schematic diagrams of connector assembly 3, socket-type connector 300, and plug-type connector 400 in another embodiment of the present invention. Compared with the connector assemblies of the above embodiments, the connector assembly disclosed in this embodiment can achieve better thinning and more complete electromagnetic shielding effect. As shown in the figures, similar to the previous embodiment, the socket-type connector 300 in this embodiment mainly includes an insulating shell 310, a socket top shell 320, a socket bottom shell 330, a plurality of contacts 340, a rotating rod 350, and a sliding top cover 360. The insulating shell 310, socket top shell 320, and socket bottom shell 330 are combined to form a shell assembly 301. The contacts 340 are held by a tail end of the shell assembly 301, and each contact 340 has a terminal portion 342 extending beyond the tail end of the shell assembly 301. Unlike the previous embodiments, in order to achieve thinning and better electromagnetic shielding effect, the sliding top cover 360 of the socket-type connector 300 in this embodiment is covered within the shell assembly 301. More specifically, in this embodiment, there is a space (not shown) between the insulating housing 310 and the socket top housing 320 in the housing assembly 301. This space can accommodate the sliding top cover 360 and allow it to slide horizontally within the space. Compared to the above embodiments, since the sliding top cover 360 of this embodiment covers the space between the insulating housing 310 and the socket top housing 320, the socket top housing 320 does not need to be provided with a slide rail for the sliding top cover 360 to slide. Therefore, the socket top housing 320 of this embodiment can have a complete structure without slots, thereby providing a more complete electromagnetic shielding effect. In addition, in particular, since the sliding top cover 360 slides between the insulating housing 310 and the socket top housing 320, there is no possibility of misalignment or disengagement of the sliding top cover in the vertical direction of the connector thickness. In other words, the socket top housing 320 of this embodiment does not need to be additionally configured with a vertical limiting member as in the previous embodiments. Therefore, the socket type connector of this embodiment can have a thinner volume with a smaller thickness.

[0138] like Figure 13 As shown, similar to the previous embodiment, the plug-type connector 400 of this embodiment is composed of an insulating shell 410, a plug top shell 420, a plug bottom shell 430, a contact 440, and a coaxial cable 450. Related descriptions can be found above and will not be repeated here. It should be noted that this embodiment provides several fasteners 412 on the side of the insulating shell 410, and correspondingly, several openings 422 are provided at opposite positions on the side of the plug top shell 420. When assembling the plug-type connector 400, these fasteners 412 can be tightly accommodated in the corresponding openings 422, allowing the plug top shell 420 and the insulating shell 410 to be tightly engaged, thus enhancing the tightness of the fit between the components.

On the other hand, the two wing portions 368 are arranged at the two side edges of the sliding top cover 360, and when the sliding top cover 360 is assembled to the insulating housing 310, the wing portions 368 can abut against the side walls of the sliding rail portions 312. In particular, when the receptacle top shell 320 and the insulating housing 310 are both assembled, the wing portions 368 are also positioned at one side of the retreat-stop pieces 324 of the receptacle top shell 320, as shown in Figure 14C .
