[0041] In the field of electronic devices, card edge connectors are a key connection component widely used in the connection process of various electronic devices. Their main function is to be placed on the circuit board to realize the insertion of electronic cards and ensure the stable operation of electronic devices.

[0042] However, in practical applications, when it is necessary to expand the capacity of the device, two electronic cards need to be inserted. Most existing technologies use a combination of two connectors arranged side by side to achieve this. This design takes up a lot of space and is not conducive to the miniaturization of the device.

[0043] This utility model proposes a connector module and an electronic device.

[0044] Please see Figure 1 and Figure 3 In one embodiment of this utility model, the connector module 10 includes:

[0045] The first connector 100 includes a first plastic body 110 and a first terminal assembly 120 disposed on the first plastic body 110. The first plastic body 110 is mounted on a circuit board 20. The first plastic body 110 has a first insertion interface 111 for inserting a first electronic card 30, and the first terminal assembly 120 is exposed in the first insertion interface 111 to communicate with the inserted first electronic card 30.

[0046] The second connector 200 includes a second plastic body 210 and a second terminal assembly 220 disposed on the second plastic body 210. One end of the second plastic body 210 is mounted on the circuit board 20, and the other end of the second plastic body 210 extends above the first plastic body 110 and is stacked with the first plastic body 110 in a direction perpendicular to the circuit board 20. The second plastic body 210 has a second insertion interface 211 for inserting a second electronic card 301, and the second terminal assembly 220 is exposed in the second insertion interface 211 to communicate with the inserted second terminal assembly 220.

[0047] The first connector 100 and the second connector 200 are independent of each other. The first insertion interface 111 and the second insertion interface 211 both have an insertion bevel that forms an acute angle with the circuit board 20 and are spaced apart in a direction perpendicular to the circuit board 20.

[0048] In the technical solution of this utility model, the connector module 10 includes a first connector 100 and a second connector 200. The first connector 100 has a first insertion interface 111. A first electronic card 30 is inserted into the first insertion interface 111 and communicates with the first terminal assembly 120. The second connector 200 includes a second plastic body 210 and a second terminal assembly 220. One end of the second plastic body 210 is mounted on the circuit board 20, and the other end extends horizontally and is stacked with the first connector 100 vertically, i.e., the second plastic body 210 is sleeved above the first connector 100. The second plastic body 210 is provided with a second insertion interface 211, and the opening of the first insertion interface 111 and the second insertion interface 211 is... With the ports aligned, the second connector 211 is used to insert the second electronic card 301. The second electronic card 301 is connected to the second terminal assembly 220 within the second connector 211. Since the second plastic body 210 is sleeved above the first connector 100, and the first connector 111 and the second connector 211 are vertically spaced, the first electronic card 30 and the second electronic card 301 can not only be inserted on the same side, but also inserted at different heights without interfering with each other. This allows for stable data transmission and communication. Compared to the existing technology where two connectors are arranged side-by-side or front-to-back, this reduces the footprint and improves the utilization rate of the internal space of the device. Furthermore, this structure is suitable for electronic devices with limited space.

[0049] Specifically, the connector module 10 is mounted on the circuit board 20. The connector module 10 includes a first connector 100, which includes a first plastic body 110. The first plastic body 110 serves as a support structure for the first terminal assembly 120. The first plastic body 110 needs to have good insulation properties, and the material can be thermoplastic, thermosetting plastic, etc. The first plastic body 110 is mounted on the circuit board 20 via a plug-in block. A first insertion interface 111 is provided on the front side of the first plastic body 110 for inserting a first electronic card 30. Multiple first lower slots are spaced apart on the front side of the first plastic body 110, and multiple first upper slots are spaced apart on the rear side. The first terminal assembly 120 includes a first upper terminal and a first lower terminal. The first upper terminal is inserted into the first upper slot on the rear side of the first plastic body 110. A lower terminal is inserted into a lower slot on the front side of the first plastic body 110, and the bottoms of the first upper terminal and the first lower terminal are soldered to the circuit board 20. Since the first upper slot and the first lower slot are both connected to the first plug-in interface 111, the first upper terminal and the first lower terminal are exposed at the first plug-in interface 111 and make contact with the inserted first electronic card 30. The first terminal assembly 120 is made of metal and has good conductivity and elasticity. The first upper terminal and the first lower terminal are both equipped with a fixing part in the middle and welding parts and contact parts extending from both ends of the fixing part, respectively. The welding part is exposed outside the first plastic body 110 for soldering to the circuit board 20, and the contact part is bent above the fixing part. The first connector 100 also includes a grounding plate and other structures. The grounding plate plays a grounding role, which can effectively prevent electromagnetic interference and ensure the stability of signal transmission.

[0050] The second connector 200 includes a second plastic body 210 and a second terminal assembly 220. One end of the second plastic body 210 is mounted on the circuit board 20 and can be electrically connected by soldering to ensure the stability of signal transmission. The front side of the second plastic body 210 has a second insertion interface 211 for inserting a second electronic card 301. The second electronic card 301 is electrically connected to the second terminal assembly 220 within the second insertion interface 211. The end of the second plastic body 210 away from the circuit board 20 extends horizontally until it connects with the first plastic body 110 in a direction perpendicular to the circuit board 20. The components are stacked upwards, and it is important to note that the first and second insertion ports are spaced apart from top to bottom, so that the first electronic card 30 and the second electronic card 301 are inserted in the same direction. This avoids increased space occupation due to different insertion directions and can improve insertion efficiency. The end of the second plastic body 210 away from the mounting plate is located above the first connector 100, making full use of the space perpendicular to the circuit board 20 and avoiding occupying too much horizontal space. Moreover, viewed from the outside of the connector module 10, the second plastic body 210 is fitted outside the first plastic body 110. The entire structure is compact and orderly, which helps to improve the overall aesthetics.

[0051] The materials of the first terminal assembly 120 and the second terminal assembly 220 need to have good conductivity and elasticity, such as phosphor bronze, beryllium bronze, pure copper or copper-nickel alloy.

[0052] Compared to the existing structure where the two connectors are arranged one in front of the other, if the rear connector is placed close to the front connector to reduce the footprint, the distance between the two connectors is shortened. When hot air is introduced between the two connectors to melt the solder paste, the small gap will increase the air pressure and air velocity in the middle, accelerating the upward dissipation of hot air and failing to meet the soldering performance. If the thickness of the rear connector is reduced, the electronic card may break through the plastic body at the rear end when it is inserted. Therefore, in this solution, a second plastic body 210 is set on top of the first plastic body 110. This reduces the footprint while ensuring sufficient contact between the hot air and the solder paste, and also prevents the second electronic card 301 from breaking through the second plastic body 210.

[0053] The first electronic card 30 and the second electronic card 301 are small storage media, typically used for data storage, communication, or identification functions, such as SD cards and CF cards. They are connected to the circuit board 20 by being inserted into the first connector 100 and the second connector 200 to achieve functions such as signal transmission, data reading, writing, and communication. The first electronic card 30 and the second electronic card 301 have the same structure, both including a card body, a storage chip, and a contact area. The contact area is used to conduct electricity with the first terminal assembly 120 / the second terminal assembly 220. The card body is usually a rectangular or square plastic shell to protect the internal components and provide physical support.

[0054] Please refer to Figure 2 In this embodiment of the present invention, the insertion side of the first insertion interface 111 is flush with the insertion side of the second insertion interface 211. This not only facilitates the user to insert the first electronic card 30 and the second electronic card 301 in the same direction, but also allows for the simultaneous insertion and removal of the two electronic cards. Furthermore, after insertion, since the first electronic card 30 and the second electronic card 301 are on the same vertical plane, it is convenient for the fastener to pass through the ends of the two electronic cards away from the insertion interface from top to bottom and fix them on the circuit board 20. This effectively prevents the first electronic card 30 and the second electronic card 301 from loosening or even falling off during use due to vibration or impact, thus improving the stability of the connection between the electronic card and the connector. Moreover, since the first electronic card 30 and the second electronic card 301 are flush, it is equivalent to completing the connection with only one fastener, reducing the number of screws and other fasteners used, reducing the overall weight and cost of the equipment, simplifying the installation process, and facilitating disassembly, maintenance, and replacement.

[0055] In an embodiment of the present invention, the second plastic body 210 is provided with an accommodating cavity 214 having an opening. The accommodating cavity 214 is located below the second insertion interface 211. The first plastic body 110 is installed in the accommodating cavity 214 through the opening, and the bottom of the first plastic body 110 faces the circuit board 20.

[0056] Please refer to Figure 6The second plastic body 210 includes a vertical section and a horizontal section. One end of the vertical section is mounted on the circuit board 20, and the other end extends in a direction perpendicular to the circuit board 20 until it is higher than the first connector 100. One end of the horizontal section is connected to the vertical section away from the circuit board 20, and the other end extends in a direction parallel to the circuit board 20, so that the second plastic body 210 is in a simple "L" shape. The horizontal section of the second insertion interface 211 is away from the end of the vertical section. The first plastic body 110 is located in the receiving cavity 214, that is, in the second insertion interface 211. Below 1, when the first connector 100 and the second connector 200 are assembled onto the circuit board 20, hot air is continuously blown in from one side of the accommodating cavity 214. Since the hot air tends to escape upwards, the horizontal section above the first connector 100 can prevent the hot air from escaping upwards. The position of the horizontal section, the vertical section and the first plastic body 110 is equivalent to providing a one-way flow channel for the hot air. The temperature is uniformly pressurized in the flow channel to ensure full contact between the hot air and the solder paste, promote the melting of the solder paste, and ensure the soldering performance requirements of the circuit board 20.

[0057] In an embodiment of this utility model, the second plastic body 210 is provided with a second upper slot 212 and a second lower slot 213 communicating with the second insertion interface 211. The insertion port of the second upper slot 212 is located on the surface of the second plastic body 210 facing away from the second insertion interface 211, and the insertion port of the second lower slot 213 faces the receiving cavity 214 and communicates with the receiving cavity 214. The second terminal assembly 220 includes a second upper row of terminals 221 and a second lower row of terminals 222. The second upper row of terminals 221 is inserted into the second upper slot 212 from the side of the second plastic body 210 away from the second insertion interface 211, and the second lower row of terminals 222 is inserted into the second lower slot 213 from the side of the second plastic body 210 provided with the second insertion interface 211.

[0058] Please refer to Figure 4 and Figure 5The second plastic body 210 includes a second upper slot 212 and a second lower slot 213. The second upper slot 212 communicates with the second connector 211 in the horizontal section. The second upper row of terminals 221 is inserted into the second upper slot 212 on the side of the second plastic body 210 away from the second connector 211. The bottom of the second upper row of terminals 221 passes through the vertical section and is soldered to the circuit board 20. The other end is exposed in the second connector 211. The second lower slot 213 communicates with the second connector 211 in the horizontal section and in the vertical section... The second lower row terminal 222 is connected to the accommodating cavity 214. The second lower row terminal 222 is inserted into the second lower slot 213 on one side of the second plastic body 210 where the second insertion interface 211 is provided. The bottom passes through the vertical section and is soldered to the circuit board 20. The top is exposed in the second insertion interface 211. In the horizontal section, the second upper row terminal 221 is higher than the second lower row terminal 222. When the second electronic card 301 is inserted into the second insertion interface 211, the upper and lower parts of the second electronic card 301 are respectively connected to the second upper row terminal 221 and the second lower row terminal 222.

[0059] In an embodiment of this utility model, the second upper row terminal 221 has a first elastic arm 2211 and a first connecting portion, and the second lower row terminal 222 includes a second elastic arm 2221 and a second connecting portion. The first elastic arm 2211 and the second elastic arm 2221 are bent in opposite directions at the second insertion interface 211 to form a contact end and are used to conduct with the electronic card. The first connecting portion and the second connecting portion are respectively connected to the circuit board 20.

[0060] Please refer to Figure 6 , Figure 7 and Figure 8The second upper row of terminals 221 includes a first elastic arm 2211 and a first connecting portion connected in sequence. The first elastic arm 2211 is located in the first upper slot of the horizontal section and bends upward, with the bend exposed at the second insertion interface 211. The first connecting portion is located in the second upper slot 212 of the horizontal section and extends downward within the second upper slot 212 of the vertical section until it is soldered to the circuit board 20. The second lower row of terminals 222 includes a second elastic arm 2221 and a second connecting portion connected in sequence. The second elastic arm 2221 bends downward within the second lower slot 213 of the horizontal section, with the bend exposed at the second insertion interface 211. The second connecting portion is located in the second lower slot 213 of the horizontal section and extends downward within the second lower slot 213 of the vertical section until it is soldered to the circuit board 20. Because the first elastic arm 2211 and the second elastic arm 2221 are bent at the second insertion interface 211, therefore... The second electronic card 301, exposed at a certain angle to the second insertion interface 211, can be inserted obliquely or horizontally. When the second electronic card 301 is inserted obliquely into the second insertion interface 211, the first elastic arm 2211 and the second elastic arm 2221 undergo elastic deformation to adapt to the angle of the second electronic card 301. The first elastic arm 2211 and the second elastic arm 2221 also provide a certain pressure when the second electronic card 301 is inserted to ensure stable contact with the second electronic card 301. As the second electronic card 301 is inserted deeper, it is then pressed flat, and the second upper row terminal 221 and the second lower row terminal 222 gradually return to a position parallel to the second electronic card 301, achieving a stable electrical connection. Similarly, when the second electronic card 301 is inserted horizontally, the elastic structure of the first connecting part and the second connecting part provides contact pressure to ensure the stability of signal transmission.

[0061] In one embodiment, the first connecting portion includes a first welding segment 2212, a first base 2213, and a second base 2214 connected in sequence. The two ends of the first base 2213 are respectively bent perpendicularly to the first welding segment 2212 and the second base 2214. The first welding segment 2212 is connected to the circuit board 20, and the second base 2214 is connected to the first elastic arm 2211.

[0062] The second connecting part includes a second welding segment 2222, a first connecting body 2223, a second connecting body 2224, a third connecting body 2225, and a fourth connecting body 2226 connected in sequence. The second welding segment 2222 is connected to the circuit board 20. The two ends of the first connecting body 2223 are respectively bent perpendicularly to the second welding segment 2222 and the second connecting body 2224. The two ends of the third connecting body 2225 are respectively bent perpendicularly to the fourth connecting body 2226 and the end of the second connecting body 2224 away from the first connecting body 2223. The fourth connecting body 2226 is connected to the second elastic arm 2221.

[0063] Please refer to Figure 8 The first soldering segment 2212 is bent and connected to the first substrate 2213. The first soldering segment 2212 is soldered to the circuit board 20. The bending of the first soldering segment 2212 can increase the contact area between the second upper row terminal 221 and the circuit board 20. Solder paste can better fill the connection between the first soldering segment 2212 and the circuit board 20, making the connection more secure and preventing the second upper row terminal 221 from detaching from the circuit board 20. In addition, the bending of the first soldering segment 2212 can also effectively transfer heat to the circuit board 20, improving the heat dissipation effect. The first substrate 2213 is located in the second upper slot 212 in the vertical segment, and the second substrate 2214 is located in the second upper slot 212 in the horizontal segment. The second substrate 2214 extends from the first substrate 2213 toward the second plug-in interface 211 and is connected to the first elastic arm 2211. This makes the distance between the first elastic arm 2211 and the first soldering segment 2212 larger, which helps to reduce signal interference, improves high-frequency performance, and improves the integrity and efficiency of signal transmission.

[0064] Similarly, the second soldering segment 2222 is bent and connected to the first connector 2223. The bending of the second soldering segment 2222 increases the contact area with the circuit board 20, allowing the solder paste to better fill the connection between the first soldering segment 2212 and the circuit board 20, making the connection more secure and preventing the second lower row of terminals 222 from detaching from the circuit board 20. The first connector 2223 is located in the second lower slot 213 within the vertical segment, and the second connector 2224 is located in the second lower slot 213 within the horizontal segment and extends horizontally. The third connector 2225 is bent and connected vertically to the second connector 2224. Extending upwards, one end of the fourth connector 2226 is bent and connected to the third connector 2225, and the other end is connected to the second elastic arm 2221. A mounting hole 2228 is formed between the fourth connector 2226, the third connector 2225 and the second connector 2224. Correspondingly, a limiting part 215 is provided on the side of the second plastic body 210 where the second insertion interface 211 is provided. When the second lower row terminal 222 is inserted into the second lower slot 213 from the front side of the second plastic body 210, the limiting part 215 is inserted into the mounting hole 2228, further limiting the second lower row terminal 222.

[0065] In the embodiments of this utility model, both the first substrate 2213 and the second substrate 2214 are provided with through holes 2215. The through holes 2215 are formed by hollowing out the first substrate 2213 in the vertical direction to make the high-frequency performance more stable. The through holes 2215 are formed by hollowing out the second substrate 2214 in the horizontal direction to increase the buffer when the second upper row of terminals 221 is inserted into the rear side of the second plastic body 210, and to increase the toughness of the second upper row of terminals 221. In addition, the through holes 2215 can reduce the weight, thereby reducing the production cost, and can change the inductance and capacitance characteristics of the second upper row of terminals 221 to reduce interference with the signal.

[0066] Please refer to Figure 7 and Figure 8 In this embodiment of the present invention, a first limiting groove is provided in the second upper slot 212, and a first hooking part 2216 is provided in the first connecting part. The first hooking part 2216 engages with the first limiting groove. The cooperation between the first hooking part 2216 and the first limiting groove allows the second upper row terminal 221 to be stably inserted into the second upper slot 212, which helps the second upper row terminal 221 to maintain a precise position in the second upper slot 212, so that the first elastic arm 2211 is in stable contact with the second electronic card 301. It also helps to maintain the consistency of the installation position and state of each second upper row terminal 221, and effectively prevents the second upper row terminal 221 from falling out of the second upper slot 212, thereby improving the structural stability of the entire connector.

[0067] In another embodiment, please refer to Figure 6 and Figure 8 The second lower slot 213 is provided with a second limiting groove, and the second connecting part is provided with a second hooking part 2227. The second hooking part 2227 is engaged with the second limiting groove. As in the above embodiment, this helps the second lower row terminal 222 to maintain a precise position in the second lower slot 213, and ensures the consistency of the installation positions of multiple second lower row terminals 222, and effectively prevents them from falling out in the second lower slot 213.

[0068] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The connector module 10 also includes a connecting block 223, which includes a plug-in part and a mounting part. The plug-in part is plugged into the second plastic body 210, and the mounting part is mounted on the circuit board 20. The connecting block 223 is configured to provide mechanical support between the second plastic body 210 and the circuit board 20, so as to prevent the second connector 200 from loosening due to external force during installation and to provide stability for the second connector 200.
