Description

Technical Field

[0001] This utility model relates to the technical field of signal transmitters, and in particular to a chip card socket connector. Background Technology

[0002] Please see Figure 1 , Figure 2 , Figure 3 , Figure 1 A three-dimensional structural view of a conventional chip socket connector in the prior art is shown. Figures 1-3 The attached diagram is labeled as follows: 2-Base, 3-Chip, 4-Card slot. Figure 1 As can be seen, the chip card socket connector includes a card insertion channel 4 and a base 2. The base 2 has a side opening, an elastic pressure plate is provided on the top side of the base 2, and a card socket contact terminal is provided on the bottom side of the base 2. The card socket contact terminal is a fixed terminal used for electrical contact. Figure 2 The illustration shows the chip entering the card insertion channel 4 from the side opening in the insertion direction, and the chip being pressed into the card insertion channel 4. Figure 3 The diagram illustrates how, after the chip is pressed into the card slot, it compresses the elastic clip, causing the clip to deform. The chip is then subjected to a downward pressing force from the top elastic clip, pushing it towards the card slot contact terminal, resulting in tight contact between the chip and the card slot contact terminal. Figures 1-3 As shown, conventional chip socket connectors are one-piece structures, with the chip pushed into the insertion channel through an opening on the side. In existing technology, insert-type chip sockets are typically used. The top and bottom of the socket are one-piece structures, with an opening on the side containing the insertion channel. The chip is manually inserted and removed via this channel in both insertion and removal directions. A specific chip socket model corresponds to a specific chip model, and this correspondence is fixed and singular. Furthermore, the chip socket is a fixed, integrated structure. However, there are still aspects in the existing technology that can be further optimized: the insertion and removal of the chip through the chip socket's insertion channel generates significant friction. Repeated insertion and removal can cause significant wear and damage to the terminal contact points in the socket. Simultaneously, the insertion and removal process also causes wear on the chip itself and affects the contact effect of the corresponding contacts, impacting the lifespan of both the insert-type chip socket and the matching chip. Because the socket is a fixed, integrated structure, maintenance is inconvenient. The chip sockets can only be used with specific models and thicknesses of chips, resulting in poor product versatility. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a flip-type chip socket connector.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a chip socket connector is constructed, including a shell and a base. The shell is fixed to the base by a movable connecting device, and the two are locked by a fastening device and unlocked by an unlocking device. The movable connecting device is a shaft pivoting device or a detachable device. The shaft pivoting device includes a rotating shaft limiting device and an end of the rotating shaft. The end of the rotating shaft is disposed on the rotating shaft limiting device, and the shell pivots around the rotating shaft. The rotating shaft limiting device is a hook, and the hook is provided with a long shaft hole. The fastening device includes an active fastening component and a passive fastening component. The active fastening component actively fastens to the passive fastening component. The active fastening component is a latch, and the latch is disposed on the side of the shell. The passive fastening component is a protrusion, and the protrusion is disposed on the side of the base. The unlocking device includes an unlocking spring, and the unlocking spring is disposed on the front side of the shell. The rotating shaft has two ends, and the distance between the end faces of the two ends of the rotating shaft is greater than the distance between the two long shaft holes. The outer casing is provided with a long shaft hole, an elastic pressure plate, a fastener, and an unlocking spring. The outer casing is a one-piece molded part.

[0005] The present invention offers the following advantages: By adopting a flip-top structure, it achieves a plug-and-play connection between the chip and the socket, solving the problems associated with traditional plug-and-play methods. Traditional chip removal is inconvenient; the flip-top chip socket connector of this invention solves the technical problem of difficult maintenance. The use of an elastic pressure plate and socket contact terminals capable of elastic deformation allows the chip socket connector to adapt to chips of different thicknesses, no longer limited to a single model and thickness. This increases the product's versatility and enhances its market competitiveness, enabling it to meet the application needs of chips of varying thicknesses, improving its universality and ease of use. This chip socket connector is compatible with chips of various thicknesses and can be used in applications such as wireless communication base stations. Attached Figure Description

[0022] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0023] Please see Figure 4The attached figures are labeled as follows: 1-housing, 11-hook, 111-long shaft hole, 12-elastic pressure plate, 13-fastening position, 14-unlocking spring, 2-base, 21-rotating shaft, 211-end, 22-chip slot, 23-protrusion, 24-front wall, 25-card socket contact terminal, 3-chip. In some embodiments, the chip socket connector includes a housing 1 and a base 2, which are connected together by a pivot connection. This pivot connection is achieved by limiting the rotating shaft 21 in the long shaft hole 111.

[0024] Please see Figure 5 In some embodiments, the outer casing 1 includes a hook 11, an elastic pressure plate 12, a fastener 13, and an unlocking spring 14. The hook 11 is provided with a long shaft hole 111. The elastic pressure plate 12 is provided on the top side of the outer casing 1, the unlocking spring 14 is provided on the front side of the outer casing 1, and the fastener 13 and the hook 11 are provided on both sides of the outer casing 1.

[0025] Please see Figure 6 In some embodiments, the base 2 includes a rotating shaft 21, an end portion 211, a chip slot 22, a protrusion 23, a front wall 24, and a card holder contact terminal 25. The end portion 211 of the rotating shaft 21 is located on the side of the base 2, and the side of the base 2 is also provided with a protrusion 23, which is used to engage with the latch 13 of the housing 1. The card holder contact terminal 25 is located on the bottom side of the base 2, and the chip slot 22 is located above the contact terminal 25 of the base 2. When the chip is placed in the chip slot 22, the chip presses downward against the contact terminal 25. Because the card holder contact terminal 25 is an elastic arc-shaped component, the contact terminal 25 provides an upward supporting force to the chip. The arc shape of the card holder contact terminal 25 ensures good contact between the card holder contact terminal 25 and the chip.

[0026] See also Figure 4 , Figure 5 and Figure 6In some embodiments, this utility model discloses a chip socket connector, including a housing 1 and a base 2. The housing 1 has lugs 11 and latches 13 on both sides. The lugs 11 are provided with elongated holes 111. The front of the housing 1 has an unlocking spring 14. The base 2 has protruding ends 211 of rotating shafts 21 and protrusions 23 on both sides. The front of the base 2 has a front wall 24, and the bottom of the base 2 has a socket contact terminal 25. The ends 211 of the rotating shafts 21 on both sides of the base 2 are disposed within the elongated holes 111 of the lugs 11 of the housing 1, thus limiting the rotating shafts 21 on both sides of the base 2 within the elongated holes 111. The housing 1 can be moved within the elongated holes 111 and along the long axis of the elongated holes to adjust the relative positional relationship between the housing 1 and the base 2. The housing 1 pivots about the axis of the rotating shafts 21 toward the base 2, and the housing 1 is fastened to the top of the base 2. The outer casing 1 moves horizontally toward the front wall 24, engaging the latch 13 with the protrusion 23, with the unlocking spring 14 abutting against the front wall 24, and the chip socket connector in the engaged state. Moving the unlocking spring 14 away from the front wall 24 horizontally, simultaneously moving the outer casing 1 away from the front wall 24, separates the latch 13 from the protrusion 23, and the chip socket connector is unlocked. The long shaft hole has a long shaft and a short shaft, with the short diameter of the long shaft hole slightly larger than the diameter of the rotating shaft, allowing the rotating shafts to match each other in the short diameter direction of the long shaft hole, thus limiting their position. The rotating shaft can slide in the long diameter direction of the long shaft hole to adjust the positional relationship between the outer casing 1 and the base 2.

[0027] Please see Figure 7 , Figure 8 , Figure 9 , Figure 10 In some embodiments, the housing 1 further includes an elastic pressure plate 12, which is disposed on the top side of the housing 1. After the chip 3 is inserted into the chip slot 22 of the base 2, the housing 1 pivots around the rotation axis 21 toward the base 2. The elastic pressure plate 12 forms an elastic interference with the chip 3, and the elastic pressure plate 12 deforms to press tightly against the surface of the chip 3, forming an elastic clamping force to ensure reliable contact between the chip 3 and the contact terminal 25 of the card slot. The elastic pressure plate 12 disposed on the top side of the housing 1 presses the chip 3 downward, and the elastic pressure plate 12 and the chip 3 squeeze each other. The chip 3 squeezes and deforms the elastic pressure plate 12, and in turn, the elastic pressure plate 12 provides a greater downward pressure to the chip 3, so that the chip 3 is more securely fixed in the chip slot. Since the elastic pressure plate 12 is an elastic element, it can give the chip 3 a certain thickness space during the appropriate deformation process. Therefore, the elastic pressure plate 12 can match chips with a certain thickness range.

[0028] Please continue reading. Figure 7 , Figure 8 , Figure 9 , Figure 10 In some embodiments, when the chip socket connector is in the open position, the chip 3 is inserted into the socket slot. Then, the housing 1 is pivoted toward the base 2 about the rotation axis 21. When the latch 13 of the housing 1 is blocked by the protrusion 23 of the base 2 and cannot fully latch the housing 1 onto the base 2, the housing 1 is moved along the long axis direction of the long axis hole 111 in the opposite direction to the front wall 24, the unlocking spring 14 deforms, so that the latch 13 is no longer blocked by the protrusion 23, and the housing 1 continues to pivot toward the base 2 about the rotation axis 21. When the top plane of the housing 1 is parallel to the bottom plane of the base 2, and the housing 1 is limited by the base 2 in the parallel plane, the housing 1 is moved along the long axis direction of the long axis hole 111 in the direction toward the front wall 24 (e.g. Figure 10 As shown in ②), unlock the spring clip to restore deformation and yield (as shown in ②). Figure 10 As shown in ①), push it in until the buckle 13 and the protrusion 23 are completely engaged (as shown in ①). Figure 10 (As shown in ③).

[0029] Please see Figure 11 In some embodiments, the elastic pressure plate 12 is made of metal. Compared to elastic pressure plates made of materials such as plastic, metal elastic pressure plates have higher fatigue strength and better wear resistance. Moreover, the elastic deformation of metal elastic pressure plates is greater than that of elastic pressure plates made of materials such as plastic.

[0030] Please continue reading. Figure 11 In some embodiments, the base 2 is an insulating gel base. The insulating gel base 2 ensures that during product use, the user will not be harmed by leakage current or accumulated static electricity due to the non-insulating material of the base 2. Furthermore, since the card slot contact terminal 25 is necessarily a metal contact terminal, placing the contact terminal 25 inside the insulating gel base 2 effectively electrically isolates the contact terminal 25 from other contact terminals, preventing the contact terminal 25 from being accidentally subjected to uncontrollable electrical contact.

[0031] Please continue reading. Figure 11In some embodiments, the elastic pressure plate 12 is an arc-shaped component. During the mutual compression of the elastic pressure plate 12 and the chip, the elastic pressure plate is deformed by the chip. During deformation, the surface of the elastic pressure plate 12 in contact with the chip also changes accordingly. Since the elastic pressure plate is arc-shaped, this ensures that the elastic pressure plate 12 always has a cross-section in contact with the chip surface during deformation, providing a stable contact point to exert continuous downward pressure on the chip. Simultaneously, because the elastic pressure plate 12 is arc-shaped, during its deformation (during the mutual compression between the elastic pressure plate 12 and the chip), the deformation of the elastic pressure plate 12 allows for some space to be provided for the chip, enabling the chip socket connector to accommodate thicker chips. After replacing with a thicker chip, the arc-shaped elastic pressure plate 12 can again have a cross-section to match the new chip.

[0032] Please continue reading. Figure 11 In some embodiments, the card slot contact terminal 25 is an arc-shaped component. After the chip is inserted into the chip slot 22 of the base 2, the housing 1 pivots around the rotation axis 21 toward the base 2. The elastic pressure plate 12 forms an elastic interference with the chip, and the elastic pressure plate 12 deforms to press tightly against the chip surface, forming an elastic clamping force to ensure reliable contact between the chip and the card slot contact terminal 25. The card slot contact terminal 25 is an elastic arc-shaped component. The elastic pressure plate 12, located on the top side of the housing 1, presses the chip downward. The elastic pressure plate 12 and the chip squeeze each other, and the chip and the card slot contact terminal 25 squeeze each other. The chip deforms the elastic pressure plate 12, and in turn, the elastic pressure plate 12 provides greater downward pressure to the chip. At this time, the card slot contact terminal 25 is subjected to downward pressure from the chip, causing the card slot contact terminal 25 to undergo elastic deformation. This further compresses the space of the card slot contact terminal 25, allowing the compressed card slot contact terminal 25 to give way to a larger thickness space for the chip, so that the chip card slot and the machine can accommodate chips with a larger thickness range. The card slot contact terminal 25 is an arc-shaped component, which allows for a new tangential surface to match the new chip after replacing it with a thicker one. The arc shape of the card slot contact terminal 25 ensures that there is always a contact surface between the chip and the card slot contact terminal 25 during contact. This guarantees effective contact between the card slot contact terminal 25 and the chip in the chip slot 22, reducing the possibility of incomplete contact and further improving the reliability and stability of the product.

[0033] Please see Figure 12 In some embodiments, the unlocking spring 14 is an elastic arc-shaped component. For example... Figure 12As shown, the dashed line ④ represents the position of the outer shell 1 in the unlocked state, and the solid line ⑤ represents the position of the outer shell 1 in the latched state. When a force F is applied to the outer shell 1 in the direction of the arrow, the unlocking spring 14 of the outer shell 1 deforms, and the outer shell 1 moves in the direction of the arrow. The unlocking spring 14 is an elastic arc-shaped component that ensures that regardless of whether the chip socket connector is in the unlocked or latched state, the unlocking spring 14 always has a cut surface in contact with the front wall 24 of the base 2. When the chip socket connector switches from the unlocked state to the latched state, the deformation of the unlocking spring 14 in the latched state is greater than that in the unlocked state. The unlocking spring 14 is an elastic arc-shaped component, ensuring that there is always a cut surface in contact with the front wall 24 of the base 2 during the switching between the two states. This makes the unlocking spring 14 always close to the front wall 14 of the base 2, and the latching of the latch 13 and the protrusion 23 cooperates to lock the unlocking spring 14 onto the front wall 14, so that the outer shell 1 can be securely latched onto the base 2. The unlocking spring 14 is made of metal, which gives it a greater recoverable deformation. The metal unlocking spring 14 has higher fatigue strength and better wear resistance. Furthermore, the elastic deformation of the metal unlocking spring 14 is greater than that of an unlocking spring 14 made of, for example, plastic.

[0034] Continue to refer to Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 Figure 12 In some embodiments, the outer shell 1, containing the elongated hole 111, the elastic pressure plate 12, the latch 13, and the unlocking spring 14, is a one-piece molded component. The one-piece molding of the outer shell 1 enhances the stress strength between the components. Because the outer shell 1 is a one-piece molded component, its overall stress strength is necessarily greater than that of a non-one-piece molded component. In particular, the elastic pressure plate 12 deforms under the pressure of the chip; if the elastic pressure plate 12 were fixed to the outer shell 1 using non-one-piece molding processes such as welding or pressing, its strength would be significantly reduced. The one-piece molding manufacturing process of the outer shell 1 improves the product's stress performance and overall quality.

[0035] Continue to refer to Figure 6In some embodiments, the rotating shaft 21 has two ends 211, and the distance between the end faces of the two ends 211 is greater than the distance between the two elongated shaft holes 111. This ensures that when the two ends 211 of the rotating shaft 21 are inserted into the elongated shaft holes 111, the two ends 211 will not fall out of the elongated shaft holes 111 because the distance between the end faces of the two ends 211 is less than the distance between the two elongated shaft holes 111. This improves the firmness of the fit between the rotating shaft 21 and the elongated shaft holes 111, and further enhances the stability and reliability of the product.

[0036] Please continue reading. Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12In some embodiments, a chip socket connector includes a housing 1 and a base 2. The housing 1 is fixed to the base 2 via a movable connecting device, and the two are locked by a fastening device and unlocked by an unlocking device. The movable connecting device can take various forms. For example, a rotation axis limiting device can be provided on the side of the base, with the rotation axis positioned within the limiting device, allowing the housing 1 to rotate around the axis. Alternatively, the housing 1 can be directly fastened to the base, where the housing 1 and base 2 are independent entities. The housing 1 and base 2 are engaged by multiple fastening devices on the housing and its multiple sides. In some embodiments, the movable connecting device is a pivoting device or a detachable device. The pivoting device includes a rotation axis limiting device and an end 211 of a rotation axis 21. The end 211 of the rotation axis 21 is positioned on the limiting device, and the housing 1 pivots around the rotation axis 21. In some embodiments, the limiting device is a lug 11 with a long shaft hole 111. In some embodiments, the fastening device includes an active fastening member and a passive fastening member, wherein the active fastening member actively fastens to the passive fastening member. The active fastening member may be a lock head, and the passive fastening member may be a lock body, which can lock together. The active fastening member may be a protrusion, and the passive fastening member may be a concave part, which lock together through their concave and convex shapes. The active fastening member may be a latch 13, which is disposed on the side of the housing 1. The passive fastening member may be a protrusion 23, which is disposed on the side of the base 2. The latch 13 and the protrusion 23 fasten together to fasten the housing 1 and the base 2. In some embodiments, the unlocking device includes an unlocking spring 14, which is disposed on the front side of the housing 1. In some embodiments, the rotating shaft 21 has two ends 211, and the distance between the end faces of the two ends 211 is greater than the distance between the two elongated shaft holes 111. This ensures that the rotating shaft 21 and its two ends 211 are confined between the elongated shaft holes 111, preventing the rotating shaft 21 and its two ends 211 from falling out even if the length of the rotating shaft 21 is shorter than the distance between the two elongated shaft holes 111. In some embodiments, the housing 1 includes elongated shaft holes 111, elastic pressure plates 12, latches 13, and unlocking springs 14. The housing 1 is a one-piece molded part. The one-piece molding of the housing 1 is beneficial for enhancing the stress strength between the various components on the housing 1.
