[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0031] At present, most card socket connectors on the market have independent ejection mechanisms and locking mechanisms, which are not only complex in structure but also have low space utilization and fail to meet the requirements of lightweight design of mobile electronic devices. To solve this problem, the utility model proposes a card socket connector.

[0032] See also Figures 1 to 4 The card socket connector 100 of the utility model includes a card socket 10, a card tray 20 and an ejection mechanism 30. The card socket 10 is provided with a card slot 111. The card socket 10 is provided with a cantilever 112 on the bottom wall of the card slot 111. The free end of the cantilever 112 is provided with a locking block 113. The card tray 20 is slidably arranged in the card slot 111. The side of the card tray 20 facing the card socket 10 is concavely provided with a stop groove 21 for accommodating the locking block 113. The ejection mechanism 30 includes a push rod 31 and an ejection member 32. The push rod 31 is installed in the card socket 10 so as to be movable forward and backward. The side of the push rod 31 facing the cantilever 112 is provided with a first pressing block 311 for pressing down the locking block 113. The ejection member 32 is rotatably installed at the inner end of the card socket 10. The ejection member 32 has a first end in contact with the card tray 20 and a second end in contact with the push rod 31. When the card tray 20 slides into the card slot 111, the locking block 113 is locked into the anti-retraction groove 21 to lock the card tray 20. After pressing the push rod 31, the first pressing block 311 presses the locking block 113 downward, and the locking block 113 is pulled out of the anti-retraction groove 21. The pop-up member 32 rotates under the push of the push rod 31 to pop out the card tray 20.

[0033] The present card socket connector 100 can be applied to mobile devices such as mobile phones, tablets and phone watches for loading and reading SIM cards or SD cards. The embodiment of the present card socket connector 100 includes a card socket 10 and a card tray 20, wherein the card tray 20 is provided with a receiving slot for placing a SIM card or an SD card, and the card socket 10 is provided with a card slot 111 for accommodating the card tray 20, and the card tray 20 is slidably installed in the card slot 111. In order to achieve the locking and sliding out of the card tray 20, a cantilever 112 is dug on the bottom wall of the card slot 111, and the cantilever 112 has a fixed end and a free end, and a locking block 113 is protruded on the side of the free end facing the card tray 20, and the free end has a certain bending performance and elastic force, and can bend with the fixed end as the center when under pressure, and return to its original state after the pressure disappears. At the same time, the card holder 10 is also provided with a push rod 31 that can move forward and backward. The forward and backward direction here refers to the sliding direction of the card tray 20. The push rod 31 is adjacent to and parallel to the cantilever 112. A first pressing block 311 for pressing down the locking block 113 is convexly provided on one side of the push rod 31 facing the cantilever 112. In addition, a pop-up member 32 is rotatably installed at the inner end of the card holder 10. The pop-up member 32 has a first end in contact with the card tray 20 and a second end in contact with the push rod 31.

[0034] The working principle of the card socket connector 100 is as follows: when the card tray 20 slides into the card slot 111 under the action of external force, the card tray 20 and the locking block 113 press against each other to press the locking block 113 down. When the stop groove 21 slides to be opposite to the locking block 113, the pressing force of the locking block 113 disappears and the locking block 113 is inserted into the stop groove 21, thereby locking the card tray 20. At this time, the first end of the pop-up member 32 contacts the inner end of the card tray 20, the second end of the card tray 20 contacts the push rod 31, and the first pressing block 311 contacts the locking block 113. When the card tray 20 needs to be ejected to remove or place the memory card, the push rod 31 is pressed to move the push rod 31 inward, and the first pressing block 311 and the locking block 113 move relative to each other. The first pressing block 311 presses the locking block 113 downward, and the locking block 113 withdraws from the retaining groove 21 to unlock the card tray 20. At the same time, the inward movement of the push rod 31 will drive the ejection member 32 to rotate, thereby ejecting the card tray 20.

[0035] From the above process, it can be seen that the card socket connector 100 cooperates with the pop-up mechanism 30 by setting a locking block 113 to achieve quick insertion and locking of the card tray 20, so that the card socket 10, the card tray 20 and the pop-up mechanism 30 have a compact structure, thereby meeting the requirements of a lightweight design.

[0036] Reference Figure 3In one embodiment of the utility model, the locking block 113 includes a stop portion 1131 and an unlocking portion 1134 that are integrally connected, the stop portion 1131 is located at one end of the locking block 113 facing the card slot 111, and the unlocking portion 1134 is located at one end of the locking block 113 away from the card slot 111, wherein the stop portion 1131 is used to snap into the stop groove 21, and the shape of the stop groove 21 matches the shape of the stop portion 1131, and the unlocking portion 1134 is used to contact and press the first pressing block 311.

[0037] The stopper 1131 and the unlocking portion 1134 both have an end close to the ejection member 32 and an end away from the ejection member 32. The top surface of the end of the stopper 1131 close to the ejection member 32 is set as the first flat surface 1132, and the top surface of the end of the stopper 1131 away from the ejection member 32 is set as the first guide surface 1133. The first guide surface 1133 obliquely connects the first flat surface 1132 and the cantilever 112. The top surface of the end of the unlocking portion 1134 close to the ejection member 32 is set as the second guide surface 1135, and the top surface of the end of the unlocking portion 1134 away from the ejection member 32 is set as the third guide surface 1136. The third guide surface 1136 is coplanar with the first guide surface 1133, and the third guide surface 1136 is symmetrically arranged with the second guide surface 1135.

[0038] Reference Figure 6 The first pressing block 311 has a first end face facing the pop-up member 32 and a second end face away from the pop-up member 32, the first end face is set as a fourth guide surface 3111, and the second end face is set as a fifth guide surface 3112, the inclination angle of the fourth guide surface 3111 is consistent with the inclination angle of the third guide surface 1136, and the inclination angle of the fifth guide surface 3112 is consistent with the inclination angle of the second guide surface 1135.

[0039] The first pressing block 311 has a first position and a second position. In the initial state, the first pressing block 311 is in the first position. At this time, the fourth guide surface 3111 of the first pressing block 311 is in contact with the third guide surface 1136 of the unlocking portion 1134. When the push rod 31 is pushed inward, the fourth guide surface 3111 of the first pressing block 311 and the third guide surface 1136 of the unlocking portion 1134 move relative to each other, thereby pressing the locking block 113 downward, unlocking the card tray 20, and moving the push rod 31 to the second position. At this time, the fifth guide surface 3112 of the first pressing block 311 is in contact with the second guide surface 1135 of the locking block 113. After the card tray 20 is pulled out, the push rod 31 is reset, and the fifth guide surface 3112 of the first pressing block 311 and the second guide surface 1135 of the locking block 113 move relative to each other, thereby pressing the locking block 113 downward, and the first pressing block 311 moves back to the first position.

[0040] At the same time, a second pressing block 22 is protruded from one side of the card tray 20 facing the card holder 10. Figure 4 The second pressing block 22 is located on the side of the stop groove 21 facing the ejection member 32, and the end surface of the second pressing block 22 facing the ejection member 32 is set as the sixth guide surface 221, and the inclination angle of the sixth guide surface 221 is consistent with the inclination angle of the first guide surface 1133. When the card tray 20 slides into the card slot 111, the sixth guide surface 221 of the second pressing block 22 first contacts and presses the first guide surface 1133 of the locking block 113, thereby achieving smooth movement of the card tray 20.

[0041] In summary, the setting of the guide surface of the locking block 113 can facilitate the smooth movement of the push rod 31 and the card tray 20, thereby achieving easy card insertion and removal.

[0042] Reference Figure 1 and Figure 7 The card holder 10 includes a tray 11 and a plastic shell 12. The plastic shell 12 is arranged on one side of the tray 11 and is integrally connected to the tray 11. The card slot 111 is recessed in the tray 11 for accommodating the card holder 20. The inner end of the plastic shell 12 is provided with an installation gap 121. The pop-up member 32 is clamped in the installation gap 121 to be rotatably connected to the plastic shell 12. The end of the plastic shell 12 away from the pop-up member 32 is provided with a guide channel 122 connected to the installation gap 121. The push rod 31 is penetrated through the guide channel 122 to contact and abut with the pop-up member 32.

[0043] Reference Figure 5 In the present card socket connector 100, the pop-up mechanism 30 also includes a button 33 and a spring 34. The button 33 is arranged at one end of the push rod 31 away from the pop-up member 32, and is used to drive the push rod 31 to move. The spring 34 is sleeved on the push rod 31, and one end of the spring 34 is connected to the button 33, and the other end of the spring 34 is connected to the plastic shell 12. The spring 34 is used to drive the push rod 31 to automatically reset.

[0044] The ejection member 32 is rotatably connected to the plastic shell 12 via a pin 35. As we know, the pin 35 is usually a cylindrical metal rod having a first end and a second end that are oppositely disposed, and the first end and the second end are often flat, so the pin 35 is easy to fall off from the pin hole 35. Fig. 9In order to avoid this phenomenon, the present technical solution provides a boss 351 at the first end and / or the second end of the pin 35, and the diameter of the boss 351 is larger than the diameter of the pin 35. At the same time, both ends of the pin 35 hole are also processed into countersunk hole shapes matching the boss 351, thereby effectively preventing the pin 35 from falling off. In the actual manufacturing process, the cylindrical pin 35 is first inserted into the pin 35 hole, and then welding is performed at both ends of the pin 35 to form the required boss 351. After welding is completed, the boss 351 will form an integral connection with the pin 35 during the cooling process, ensuring the stability and reliability of the pin 35 in the pin 35 hole.

[0045] Reference Figure 1 and Figure 8 In one embodiment of the utility model, the card holder 10 is provided with two oppositely arranged detection terminals 114 on the bottom wall of the card slot 111, and the card tray 20 is provided with a wiring terminal 23 on the side facing the card holder 10. When the card tray 20 slides into the card slot 111, the wiring terminal 23 slides between the two detection terminals 114 and connects the two detection terminals 114. When the card tray 20 slides into the card slot 111 to a specified position, the wiring terminal 23 is just located between the two detection terminals 114 to connect the two wiring terminals 23, and the system of the mobile device recognizes that a card is inserted. When the wiring terminal 23 slides out with the card tray 20, the two detection terminals 114 are disconnected, and the system of the mobile device recognizes that the card is pulled out, thereby realizing the detection function when the memory card is inserted or pulled out.

[0046] Specifically, the wiring terminal 23 includes a wiring portion 231 and a clamping portion 232. The clamping portion 232 is arranged at the edge of the wiring portion 231 and is bent with the wiring portion 231. A clamping hole 24 adapted to the clamping portion 232 is opened on the card tray 20. The clamping portion 232 is inserted into the clamping hole 24 to achieve the limited installation of the wiring terminal 23 and the card tray 20.

[0047] The utility model also proposes a mobile device, which can be an electronic device such as a mobile phone, a tablet, and a phone watch. The mobile device includes a card socket connector 100. The specific structure of the card socket connector 100 refers to the above embodiment. Since the communication device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0048] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
