Description

[Technical Field]

[0001] The present invention relates to a receptacle connector, and more particularly to a receptacle connector having an electromagnetic shielding effect. [Background technology]

[0002] LVDS (Low Voltage Differential Signaling) is a data transmission technology widely used for high-speed data transmission. This technology transmits differential signals using two signal lines, achieving high-speed communication at low voltages, typically around 0.3V to 0.6V. Furthermore, LVDS is characterized by low power consumption, low noise characteristics, and excellent resistance to electromagnetic interference.

[0003] LVDS is primarily used in LCD display panels and laptops, where it is used to transmit data and control signals. It is also used in a wide range of fields requiring high-speed communication, such as communications equipment, automotive electronic systems, and industrial control devices. LVDS technology is characterized by its high-speed transmission speeds of over several hundred Mbps, and its use of a differential signal transmission method provides excellent noise resistance. This makes it particularly suitable for applications requiring high-speed operation and low power consumption.

[0004] However, in high-speed communication environments, electromagnetic fields between adjacent signal sources can interfere with each other, resulting in crosstalk and reduced data transmission accuracy. This phenomenon is particularly pronounced when wiring density is high and transmission speeds increase. Electromagnetic interference causes distortion and attenuation of signal waveforms, with the most severe impact occurring at the connection between the connector and the cable. Therefore, in the high-speed communication field, there is a strong demand for innovative connector designs that can effectively suppress electromagnetic interference and ensure stable and reliable data transmission. Summary of the Invention

[0005] One of the objectives of this invention is to provide an innovative connector with a sliding mechanism, which allows for easy assembly and automated optical inspection (AOI) while providing excellent electromagnetic shielding.

[0006] Another object of the present invention is to provide a connector equipped with a locking mechanism to prevent disconnection of the receptacle connector and plug connector. This connector employs a space-efficient, compact design, and combines the advantages of low cost, high reliability, and thinness.

[0007] To achieve the above-mentioned object, the present invention provides a receptacle connector mounted on a circuit board for mating with a plug connector having multiple coaxial cables. The receptacle connector includes a housing assembly, multiple contact members, and a sliding lid. The housing assembly has a guide portion. The multiple contact members are held in an end portion of the housing assembly. Each contact member has a terminal end extending outside the end portion of the housing assembly. The sliding lid is mounted on the guide portion and slides horizontally along the guide portion. The sliding lid has a front edge and a cover portion. The cover portion is mounted on the rear edge of the sliding lid. When the plug connector is inserted into the receptacle connector, the plug connector presses the front edge to slide the sliding lid horizontally from a first end of the guide portion to a second end opposite the first end. The cover portion covers the terminal end, providing an electromagnetic shielding effect.

[0008] In an embodiment of the receptacle connector of the present invention, the housing assembly includes an insulating housing, an upper receptacle housing, and a lower receptacle housing. The upper receptacle housing and the lower receptacle housing cover the insulating housing. The distal end of the housing assembly is an end face of the insulating housing. The terminal ends of the contact members extend from the end face.

[0009] In an embodiment of the receptacle connector of the present invention, the receptacle upper housing has an extended end surface that extends outside the end surface of the insulating housing, and when the sliding top cover slides horizontally to the second end of the guide portion, the extended end surface covers the terminal end portion together with the cover portion of the sliding top cover.

[0010] In the embodiment of the receptacle connector of the present invention, the insulating housing has a lower guide groove, and the receptacle upper housing has an upper guide groove, and the upper and lower guide grooves form a guide portion.

[0011] In an embodiment of the receptacle connector of the present invention, the sliding top cover further has two extension arms. Each extension arm extends downward from a side edge of the sliding top cover into a guide portion of the housing assembly. Each extension arm has a stopper pin. The stopper pin protrudes outside of each extension arm. The stopper pin is restricted by the guide portion of the housing assembly and slides horizontally between the first end and the second end.

[0012] In an embodiment of the receptacle connector of the present invention, the lower guide groove has a guide slope for assembling the sliding top cover to the housing assembly, and the stopper pin of the sliding top cover is guided by the guide slope and moves along the guide slope until it is positioned at the first end of the guide portion.

[0013] In an embodiment of the receptacle connector of the present invention, the receptacle upper housing has two vertical stops, and the sliding top cover further has two wings. One vertical stop is installed on each side of the receptacle upper housing adjacent to each end. When the sliding top cover slides horizontally from the first end to the second end of the guide, one of the two vertical stops limits the internal horizontal sliding of one of the two wings, preventing it from falling outward.

[0014] In an embodiment of the receptacle connector of the present invention, the receptacle upper housing has a backstop member, and when the sliding cover slides horizontally to the second end of the guide portion, the front edge of the sliding cover is restricted by the backstop member, preventing it from sliding backward.

[0015] In an embodiment of the receptacle connector of the present invention, the receptacle connector further includes a rotating lever pivotally supported on the housing assembly. When the plug connector slides the sliding top cover horizontally toward the second end, the rotating lever rotates from the first position to the second position. The rotating lever is restricted by an engaging protrusion on the side of the plug connector and is locked, preventing the plug connector from falling off the receptacle connector.

[0016] In the embodiment of the receptacle connector of the present invention, the upper receptacle housing has two support members, one on each side of the upper receptacle housing, that support the rotating lever in the first position and prevent the rotating lever from contacting the circuit board.

[0017] In the embodiment of the receptacle connector of the present invention, the guide is installed on the insulating housing, and there is a space between the insulating housing and the receptacle upper housing, and the sliding top cover can slide horizontally within the space.

[0018] In an embodiment of the receptacle connector of the present invention, the sliding top cover further has two extension arms. Each extension arm extends horizontally from the front edge of the sliding top cover into a guide portion of the housing assembly. Each extension arm is restricted by the guide portion and slides horizontally between a first end and a second end.

[0019] In an embodiment of the receptacle connector of the present invention, the insulating housing further includes at least one engaging member disposed on the top surface of the insulating housing. The sliding cover further includes at least one guide groove. The guide groove accommodates the engaging member. When the sliding cover slides horizontally from the first end to the second end of the guide portion, the engaging member limits the horizontal sliding of the guide groove and prevents it from falling off.

[0020] In an embodiment of the receptacle connector of the present invention, each engaging member has a lower positioning recess, and each guide groove has a lower positioning protrusion. When the sliding top cover slides horizontally to the second end of the guide part, the lower positioning protrusion is restricted by the lower positioning recess, preventing the sliding top cover from sliding backward.

[0021] In an embodiment of the receptacle connector of the present invention, the receptacle upper housing has at least one anti-retraction member. The sliding top cover has at least one wing portion. The anti-retraction member is a convex rib protruding from the underside of the receptacle upper housing. When the sliding top cover slides horizontally from the first end to the second end of the guide portion, the wing portion slides from one end of the anti-retraction member to the other end of the anti-retraction member, and is restricted by the convex rib to prevent backward sliding.

[0022] In an embodiment of the receptacle connector of the present invention, the receptacle connector further includes a rotating lever pivotally supported on the housing assembly. When the plug connector horizontally slides the sliding top cover toward the second end, the rotating lever rotates from a first position to a second position. The rotating lever is restricted by at least one first protrusion on a side edge of the plug connector to enter a locked state, preventing the plug connector from coming off the receptacle connector.

[0023] In an embodiment of the receptacle connector of the present invention, the receptacle upper housing further includes at least one second protrusion disposed on a side edge of the receptacle upper housing, and when the rotating lever rotates from the first position to the second position, the rotating lever is restricted by the second protrusion and locked, preventing the plug connector from falling out of the receptacle connector.

[0024] To achieve the above object, the present invention provides a connector assembly including the receptacle connector and the plug connector of the above embodiment, wherein after the plug connector is mated with the receptacle connector, one of the coaxial cables is electrically connected to one of the contact members.

[0025] Those skilled in the art will be able to fully understand the technical features, other objects and advantages of the present invention by reading the specification and accompanying drawings of the present invention. [Brief explanation of the drawings]

[0027] Hereinafter, a connector assembly according to an embodiment of the present invention will be described with reference to the drawings. In each drawing, similar components or components having the same function are designated by the same reference numerals. The drawings are not drawn to actual scale.

[0028] The components of a connector assembly according to an embodiment of the present invention will be described with reference to Figures 1 and 2. Figure 1 is a perspective view of the connector assembly according to the embodiment of the present invention in a mated state. Figure 2 is a perspective view of the connector assembly according to the embodiment of the present invention in an unmated state. As shown in Figure 1, the connector assembly 1 is installed on a substrate 2 and includes a receptacle connector 100 and a plug connector 200 that mates with the receptacle connector 100.

[0029] 3 is a schematic diagram illustrating the assembly of a receptacle connector 100 according to an embodiment of the present invention. The receptacle connector 100 of the present invention includes an insulating housing 110, an upper receptacle housing 120, a lower receptacle housing 130, multiple contact members 140, a rotating lever 150, and a sliding top cover 160. After the lower receptacle housing 130 and the insulating housing 110 are assembled, the contact members 140 are assembled into the insulating housing 110. Each contact member 140 has a terminal end 142 extending from an end face of the insulating housing 110. The terminal end 142 allows the assembled receptacle connector 100 to be soldered onto a board 2 and electrically connected to the board 2. Next, the rotating lever 150 is assembled into a receiving groove formed by the insulating housing 110 and the lower receptacle housing 130. The receptacle upper housing 120 covers the insulating housing 110 and the receptacle lower housing 130. The rotating lever 150 is limited in position between these three. The rotating lever 150 rotates around the receiving groove. The receptacle upper housing 120 has an extended end surface 122 that extends outward from the end surface of the insulating housing 110. The extended end surface 122 covers the terminal end 142 of the contact member 140 in a semi-open state. As shown in the figure, the receptacle connector 100 mainly comprises the insulating housing 110, the receptacle upper housing 120, and the receptacle lower housing 130 combined to form a housing assembly 101. The rotating lever 150 is pivotally supported by the housing assembly 101 and can rotate within a predetermined angle range around the housing assembly. Finally, the sliding top cover 160 is fitted onto the housing assembly 101. The sliding top cover 160 is horizontally slidable with a predetermined stroke relative to the housing assembly 101. Details will be described later.

[0030] FIG. 4 is an exploded perspective view of the main components of a plug connector 200 according to an embodiment of the present invention. The plug connector 200 includes an insulating housing 210, an upper plug housing 220, a lower plug housing 230, multiple contact members 240, and multiple coaxial cables 250. As shown in FIG. 4, the insulating housing 210 and the lower plug housing 230, which are used to assemble the multiple contact members 240, are first molded using insert molding. Next, multiple coaxial cables 250 connected in series by ground bars are inserted into the receiving space formed by the insulating housing 210 and the lower plug housing 230. Each coaxial cable 250 is electrically connected to its corresponding contact member 240. A hot bar process is then performed to complete the grounding of all coaxial cables 250. Finally, the upper plug housing 220 is fitted into the insulating housing 210 and the lower plug housing 230, completing the assembly process of the plug connector 200. Furthermore, each contact member 240 of the plug connector 200 has a terminal end 242. When the receptacle connector and the plug connector are mated, each terminal end 242 of the plug connector 200 comes into physical contact with each contact member 140 of the receptacle connector 100. This establishes an electrical connection between the receptacle connector and the plug connector, allowing signal transmission.

[0031] 5A and 5B. FIG. 5A is a schematic diagram of the mating process between the receptacle connector 100 and the plug connector 200 in an embodiment of the present invention. FIG. 5B is a schematic diagram of the state before mating. Specifically, the sliding top cover 160 has two front edge portions 162 located on its front edge and a cover portion 164 located on its rear edge. In a preferred embodiment, the plug upper housing 220 of the plug connector 200 has two recesses 222. When mating the receptacle connector 100 and the plug connector 200, the two front edge portions 162 of the top cover 160 are slidable. Furthermore, before the plug connector 200 is inserted into the receptacle connector 100, the sliding top cover 160 of the receptacle connector 100 is in a mating start position relative to the housing assembly 101. This is the state shown by the dashed line in step (b) of FIG. 5A. At this mating start position, the cover portion 164 of the sliding top cover 160 is in an open state, i.e., it does not cover the end portions 142 of all of the contact members 140 of the receptacle connector 100. The purpose of this is to expose the end portions 142 to the outside, making it easier for an automatic optical inspection device to perform an optical inspection of the end portions 142 and check the condition of the solder paste on the surfaces of the end portions 142. After it is confirmed that there are no problems with the inspection, the mating process of the two connectors is carried out.

[0032] 5A and 5B, when the plug connector 200 is inserted into the receptacle connector 100, two recesses 222 on the plug upper housing 220 of the plug connector 200 press against two front edges 162 of the sliding top cover 160 of the receptacle connector 100. This causes the sliding top cover 160 to slide horizontally relative to the housing assembly 101 and move to the mating completion position. At the mating completion position, the cover portion 164 of the sliding top cover 160 assumes a covering state, as shown by the dashed line in step (c) of FIG. 5A. Furthermore, as shown in FIG. 5C, the cover portion 164 cooperates with the extended end surface 122 of the receptacle upper housing 120 to cover the terminal ends 142 of all contact members 140 of the receptacle connector 100. This provides an electromagnetic shielding effect and provides complete electromagnetic protection for signal transmission.

[0033] The connector assembly 1 of the present invention is equipped with a locking function. This locking function prevents the plug connector 200 from unexpectedly disconnecting from the receptacle connector 100 due to changes in the operating environment after the plug connector 200 and the receptacle connector 100 are fully mated. For example, conventional automotive connectors are susceptible to vibrations while the vehicle is running, which can cause poor contact between the connectors. Specifically, in the present invention, after the plug connector 200 and the receptacle connector 100 are fully mated, the rotating lever 150 on the receptacle connector 100 is rotated to move the rotating lever 150 from a first position adjacent to the extended end face 122 of the receptacle upper housing 120 to a second position adjacent to the coaxial cable 250 of the plug connector 200 (see steps (c) and (d) in FIG. 5A ). When the rotating lever 150 is in the second position, as shown in FIG. 5D , the rotating lever 150 is secured by an engaging protrusion 224 provided on the side surface of the plug upper housing 220 of the plug connector 200, thereby entering a locked state. This locked state prevents the plug connector 200 from coming loose from the receptacle connector 100, ensuring that the two connectors remain securely connected even in adverse environments, thereby ensuring signal transmission quality. Furthermore, when the rotating lever 150 is rotated in the opposite direction from the second position back to the first position, the rotating lever 150 is released from the engaging protrusion 224, entering an unlocked state. After the unlocked state, the user can easily pull the plug connector 200 out of the receptacle connector 100.

[0034] The following describes in detail a method for achieving electromagnetic shielding by using the pressing force of the plug connector to completely cover the terminal ends of the contact members with the sliding cover when the receptacle connector and plug connector are mated. Figures 7 and 8A to 8C are schematic diagrams showing how the sliding cover of the receptacle connector of the present invention slides horizontally between different positions on the housing assembly. The housing assembly 101 of the receptacle connector 100 is also provided with two guide members 102. As shown in Figure 7, the sliding cover 160 has two extension arms 166 and two wings 168, which are located at the front and rear ends of both side edges of the sliding cover 160, respectively. Figure 7 shows that the guide members 102 of the housing assembly 101 are formed by the lower guide groove 112 of the insulating housing 110 and the upper guide groove 124 of the receptacle upper housing 120. Each extension arm 166 provided on either side of the sliding top cover 160 extends downward from the side edge of the sliding top cover 160 into the guide portion 102. A stopper pin 1661 protruding from the outside of each extension arm 166 is provided. The movement range of this stopper pin 1661 is limited by the guide portion 102 of the housing assembly 101. This allows the stopper pin 1661 to slide horizontally between the first end 1021 and the second end 1022.

[0035] 8A, the guide portion 102 has an assembly groove 1023 at the front end of the first end 1021. When the sliding top cover 160 is initially assembled to the housing assembly 101, the extension arms 166 on both sides of the sliding top cover 160 are inserted into the assembly groove 1023. Furthermore, the lower guide groove 112 of the insulating housing 110 has a guide slope 1122. As shown in FIG. 8B, the guide slope 1122 allows the stopper pin 1661 of the sliding top cover 160 to move along the guide slope 1122 and be positioned at the first end 1021 of the guide portion 102. As shown in the enlarged local view of FIG. 8B (to clarify the internal relationship of the structure, FIGS. 8B and 8C omit or use hidden lines to show the receptacle upper housing 120, and mainly show the partial structure of the insulating housing 110 and the sliding top cover 160), there is a certain amount of space within the assembly groove 1023 for assembling the extension arms 166 of the sliding top cover 160. As the extension arm 166 advances toward the first end 1021 (as shown by the arrows in FIGS. 8A and 8B ), the stopper pin 1661 is pressed by the guide inclined surface 1122 and receives an indirect force. The assembly groove 1023 provides the extension arm 166 with a certain amount of space, allowing it to deform appropriately and preventing damage to the contact members. After the extension arm 166 moves to the first end 1021, the structure of the extension arm 166 returns to its normal state when the external force is released. The step formed by the guide inclined surface 1122 prevents the extension arm 166 from sliding back into the assembly groove 1023, ensuring that the extension arm 166 is stably positioned at the first end 1021.

[0036] 8B and 8C show the process of sliding top cover 160 moving from first end 1021 to second end 1022 of guide portion 102. Sliding top cover 160 completely covers exposed end portions 142 of the contact members during insertion of the plug connector into the receptacle connector. Furthermore, to prevent improper vertical bounce or misalignment of sliding top cover 160 during horizontal movement, which could result in the sliding top cover not completely covering end portions 142, two vertical stops 126 are provided on receptacle upper housing 120, located on both sides of each end portion 142. As sliding top cover 160 moves horizontally from first end 1021 to second end 1022 of guide portion 102, vertical stops 126 on both sides of receptacle upper housing limit the horizontal movement of wing portions 168 of sliding top cover 160, preventing it from falling outward. As shown in FIG. 8A , when the sliding top cover 160 is initially assembled to the housing assembly 101, the extension arm 166 at one end of the sliding top cover 160 is already within the assembly groove 1023, but the wing 168 at the other end is not yet within the limiting range of the vertical stopper 126. As shown in FIG. 8B , when the extension arm 166 moves to the first end 1021, the wing 168 just enters the limiting range of the vertical stopper 126. As shown in FIG. 8C , throughout the entire horizontal stroke of the sliding top cover 160 from the first end 1021 to the second end 1022, both wings 168 remain within the limiting range of the vertical stopper 126. This design ensures that the sliding top cover 160 does not bounce or shift unexpectedly during horizontal movement. The end portion is completely covered by the cover portion 164 of the sliding top cover 160 and the extended end surface 122 of the receptacle upper housing 120, preventing external electromagnetic interference.

[0037] FIG. 9 is a schematic diagram of a receptacle connector according to a preferred embodiment of the present invention. In this embodiment, the receptacle upper housing 120 of the receptacle connector 100 further includes two anti-backout members 128. The anti-backout members 128 are disposed at positions where the upper surface of the receptacle upper housing and the front edge 162 of the sliding top cover 160 are adjacent to each other. The anti-backout members 128 are protrusions formed in a recessed structure (see FIG. 7). The recessed structure of the anti-backout members 128 is adapted to receive a portion of the front edge 162 of the sliding top cover 160. The protrusions form a downward-facing opening in the recessed structure. When the sliding top cover 160 slides horizontally toward the second end 1022 of the guide portion 102, the front edge 162 of the sliding top cover 160 is pressed by the plug connector and is partially received in the recessed structure of the receptacle upper housing. The front edge 162 is restrained by the protrusion of the anti-retraction member 128, preventing it from sliding backward. This design prevents the front edge 162 from falling off the receptacle upper housing and also ensures that the sliding top cover 160 securely covers the end portion.

[0038] As shown in FIG. 10 , the receptacle upper housing 120 in a preferred embodiment of the present invention further includes two support members 129. The support members 129 are provided on both sides of the receptacle upper housing 120 and serve to support the rotating lever 150 in the first position. When the rotating lever 150 is stopped in the first position, it is fixed at a certain distance from the board 2, preventing contact with the board 2. When the plug connector 200 is to be removed from the receptacle connector 100, force is applied to release the rotating lever 150 from the restriction of the engaging protrusion 224, and the connector assembly 1 is then rotated from the second position to the first position to unlock the plug connector 200, allowing the plug connector 200 to be removed. At this time, the rotating lever 150 is supported by the support members 129, preventing it from contacting the board 2 due to excessive rotation. Excessive rotation of the rotating lever 150 can also prevent the fixed solder points or terminals of the receptacle connector 100 from being separated from the board 2, which could affect the grounding performance.

[0039] 11 to 13 are schematic diagrams of a connector assembly 3 according to another embodiment of the present invention, and partially exploded schematic diagrams of a receptacle connector 300 and a plug connector 400, respectively. Compared with the connector assemblies of the above-described embodiments, the connector assembly disclosed in this embodiment achieves a thinner design and more complete electromagnetic shielding effect. As shown in the figures, similar to the previous embodiment, the receptacle connector 300 of this embodiment is primarily composed of an insulating housing 310, an upper receptacle housing 320, a lower receptacle housing 330, multiple contact members 340, a rotating lever 350, and a sliding top cover 360. The insulating housing 310, the upper receptacle housing 320, and the lower receptacle housing 330 combine to form a housing assembly 301. The contact members 340 are held by the end of the housing assembly 301. Each contact member 340 has a terminal end 342 extending outside the end of the housing assembly 301. Unlike the previous embodiments, the sliding lid 360 of the receptacle connector 300 of this embodiment is housed within the housing assembly 301 to achieve a thinner connector and better electromagnetic shielding. Specifically, in the housing assembly 301 of this embodiment, a space (not shown) is provided between the insulating housing 310 and the receptacle upper housing 320. This space accommodates the sliding lid 360 and allows it to slide horizontally. Compared to the previous embodiments, because the sliding lid 360 of this embodiment is housed between the insulating housing 310 and the receptacle upper housing 320, there is no need to provide a guide for the sliding lid 360 on the receptacle upper housing 320. As a result, the receptacle upper housing 320 of this embodiment has a complete structure without any openings, providing a more complete electromagnetic shielding effect. Furthermore, because the sliding lid 360 slides between the insulating housing 310 and the receptacle upper housing 320, there is no possibility that the sliding lid will fall off in the thickness direction of the connector. In other words, there is no need to provide an additional vertical stopper, as in the previous embodiment, in the receptacle upper housing 320 of this embodiment. Therefore, the receptacle connector of this embodiment achieves a thinner, more compact structure.

[0040] As shown in FIG. 13 , similar to the previous embodiment, the plug connector 400 of this embodiment is composed of an insulating housing 410, an upper plug housing 420, a lower plug housing 430, contact members 440, and a coaxial cable 450. The relevant descriptions can be found above, and will not be repeated here. Furthermore, in this embodiment, a plurality of engaging members 412 are provided on the side of the insulating housing 410. Furthermore, a plurality of openings 422 are provided at corresponding positions on the side of the upper plug housing 420. When assembling the plug connector 400, the engaging members 412 are closely received in the corresponding openings 422, bringing the upper plug housing 420 and the insulating housing 410 into a tightly fitted state, thereby increasing the bonding strength between the components.

[0041] To further explain the operating mechanism between the sliding top cover and other components in this embodiment, reference will be made to FIGS. 14A-14C and 15A-15C to describe the interaction between the sliding top cover 360 and the insulating housing 310. FIG. 14A shows the receptacle connector 300 and the plug connector 400 in this embodiment in an unmated state. At this time, the sliding top cover below the receptacle upper housing 320 is uncovered, and the terminal end 342 is exposed to the outside, allowing inspection by an automated optical inspection device. FIG. 14B is an enlarged schematic view of the portion indicated by the dashed line in FIG. 14A. In FIG. 14B, the receptacle upper housing 320 is indicated by the dashed line, clearly illustrating the interaction between the sliding top cover 360 and the insulating housing 310. FIG. 14C is a schematic cross-sectional view taken along line AA′ in FIG. 14A.

[0042] This embodiment will be described with reference to FIGS. 12 and 14B. In this embodiment, the insulating housing 310 of the housing assembly 301 has two guide portions 312 provided at two opposing ends of the receptacle upper housing 320. The receptacle upper housing 320 has an extended end surface 322 and two anti-retraction members 324. The anti-retraction members 324 are convex ribs protruding from the underside of the receptacle upper housing. The sliding top cover 360 has a plurality of front edge portions 362, a cover portion 364, two extension arms 366, and two wing portions 368. The functions of the front edge portion 362 and the cover portion 364 and the structural relationships between the other components are similar to those of the previously described embodiment, and therefore will not be described here. Another difference from the previously described embodiment is that the two extension arms 366 are each located at the front edge of the sliding top cover 360. When assembling the sliding top cover 360 to the insulating housing 310, as shown in FIGS. 12 and 14B, the extension arm 366 extends horizontally and is housed in the guide portion 312 of the insulating housing 310. Furthermore, when the assembly of the receptacle top housing 320 and the insulating housing 310 is completed, the wing portion 368 is positioned on one side of the backlash prevention member 324 of the receptacle top housing 320. This is shown in FIG. 14C. The two wings 368 are respectively disposed on both side edges of the sliding top cover 360. When assembling the sliding top cover 360 to the insulating housing 310, the wing portion 368 contacts the side wall of the guide portion 312. Furthermore, when the assembly of the receptacle top housing 320 and the insulating housing 310 is completed, the wing portion 368 is positioned on one side of the backlash prevention member 324 of the receptacle top housing 320, as shown in FIG. 14C.

[0043] The following description will be made with reference to Figures 12 and 15A to 15C. Figure 15A shows the receptacle connector 300 and plug connector 400 of this embodiment in a mated state. At this time, the sliding lid 360 below the receptacle upper housing 320 is in a covering state. The cover portion 364 of the sliding lid 360 covers the terminal end together with the extended end surface 322 of the receptacle upper housing. As described above, compared to the conventional embodiment, the receptacle upper housing 320 of this embodiment does not have a guide portion and has fewer openings. Therefore, the connector assembly of this embodiment exhibits a superior electromagnetic shielding effect. Figure 15B is an enlarged schematic view of the area surrounded by the dashed line in Figure 15A. Figure 15C is a schematic cross-sectional view taken along line BB' in Figure 15A.

[0044] When the receptacle connector 300 and the plug connector 400 begin to mate, the sliding top cover 360 receives pressure from the plug connector 400, causing the extension arm 366 to slide horizontally from the first end 3121 toward the second end 3122 of the guide portion 312. As shown in FIG. 15B , when the extension arm 366 slides to the second end 3122, the wing portion 368 overcomes the restriction of the convex rib of the back-up prevention member 324 and moves to the opposite end of the back-up prevention member 324. When the receptacle connector 300 and the plug connector 400 are completely mated, no force is applied to the sliding top cover 360. At this point, the wing portion 368 is restrained by the convex rib of the back-up prevention member 324, preventing it from moving backward. This state is shown in FIG. 15C .

[0045] In this embodiment, the vertical stability of the sliding cover 360 is improved when it slides horizontally, preventing it from shifting or bouncing. At least one engagement member 314 is provided on the top surface of the insulating housing 310. Furthermore, as shown in FIG. 12 , the sliding cover 360 is provided with at least one guide groove 369 at a position corresponding to the engagement member 314. The guide groove 369 accommodates the engagement member 314. When the extension arm 366 of the sliding cover 360 slides horizontally from the first end 3121 to the second end 3122 of the guide portion 312, as shown in FIGS. 14B and 15B , the engagement member 314 guides the horizontal sliding of the sliding cover 360 within the guide groove 369 and prevents the sliding cover 360 from falling outward, thereby improving the vertical stability during horizontal sliding.

[0046] 16 , upper positioning recesses 3141 and lower positioning recesses 3142 are provided at the upper and lower ends of both side edges of the engaging member 314, respectively. Correspondingly, upper positioning protrusions 3691 and lower positioning protrusions 3692 are provided at the upper and lower ends of both side edges of the guide groove 369, respectively. When the sliding top cover 360 begins to slide horizontally from the first end 3121 of the guide portion 312, the lower positioning protrusions 3692 in the guide groove 369 are released from the constraint of the lower positioning recesses 3142 on each engaging member 314 of the insulating housing 310. This allows sliding to the second end 3122. When the sliding top cover 360 slides horizontally to the second end 3122 of the guide portion 312, the upper positioning protrusions 3691 in the guide groove 369 are constrained by the upper positioning recesses 3141 on the engaging member 314, preventing backward sliding.

[0047] In this embodiment, when the connector assembly 3 is used, the mating reliability of the receptacle connector 300 and the plug connector 400 is improved and disengagement between them is prevented. As shown in FIG. 17 , the receptacle connector 300 and the plug connector 400 are each provided with a protrusion that limits the movement of the rotating lever, thereby preventing the plug connector 400 from disengaging from the receptacle connector 300. As shown in FIG. 17 , a protrusion 326 is provided on a side edge of the receptacle upper housing 320 of the receptacle connector 300. Furthermore, a protrusion 426 is provided on a side edge of the plug upper housing 420 of the plug connector 400. When the rotating lever 350 rotates from the first position to the second position, the movement is limited by the protrusion 426 of the plug connector 400 and the protrusion 326 of the receptacle connector 300, establishing a locked state and preventing the plug connector 400 from disengaging.

[0048] As described above, the connector assembly of the present invention comprises an innovative combination of a receptacle connector and a plug connector. The receptacle connector is equipped with a sliding lid, which allows for easy confirmation of the solder condition on the contact members through automatic optical inspection before mating the receptacle connector and plug connector. After inspection, when the receptacle connector and plug connector are mated, the sliding lid covers the entire connector assembly, providing an electromagnetic shielding effect. Furthermore, the connector assembly of the present invention is equipped with a lock / unlock mechanism for the receptacle connector and plug connector, improving operability and structural reliability. The connector assembly of the present invention achieves a compact design and low cost.

[0049] Although the present invention has been described with reference to preferred embodiments, those skilled in the art may make various modifications as appropriate within the scope of the present invention. Therefore, the present invention is not limited to the above-described embodiments, but is subject to the scope of the utility model registration claims. In other words, equivalent changes and modifications that do not depart from the scope of the utility model registration claims of the present invention shall remain within the scope of the present invention.
