[0001] This utility model relates to the field of connector technology, specifically a double-row female connector. Background Technology

[0002] With the rapid development of technology, electronic devices such as smartphones, tablets, and laptops are constantly moving towards miniaturization and multifunctionality. These devices need to integrate more and more electronic components, such as chips, sensors, and displays, within a limited space. In order to realize signal transmission and power supply between these components, connectors have become a key component.

[0003] As circuit boards inside electronic devices become increasingly complex, the number of signal and power lines increases dramatically. In high-end smartphones, hundreds of pins on the motherboard need to be connected. Traditional single-row connectors occupy too much circuit board space and cannot meet the high-density connection requirements. To solve this problem, dual-row female connectors have emerged. By adding a row of pin interfaces in the vertical direction, they effectively improve the connection density per unit area, enabling electronic devices to achieve more connection functions in a smaller space. Therefore, a dual-row female connector is proposed to address the above issues. Summary of the Invention

[0007] As described above, the second connecting block is positioned directly above the first connecting block via a plug. The first and second limiting strips are rotatably connected to the outside of the rotating shaft. The locking block and the buckle are engaged. The first and second limiting strips are symmetrically distributed on the inner wall of the placement groove.

[0008] As described above, the card block and the buckle engage inside the card slot, and the first limiting strip and the second limiting strip cover both sides of the limiting block.

[0009] As described above, the plug forms an engaging structure with the first connecting block through the cooperation of the slot, the block, the buckle and the first limiting strip.

[0010] As described above, the bottom of the clamping block is fixedly connected to an extension strip, the inner surface of the extension strip is fixedly connected to a first magnetic block, the inner surface of the first magnetic block is movably connected to a second magnetic block, the second magnetic block is fixedly connected to the top outer side of the first connecting block, the top of the first connecting block has circular grooves on both sides, the circular grooves are symmetrically distributed on the top of both sides of the placement groove, the inner surface of the circular groove is fixedly connected to a buffer spring, the top outer side of the buffer spring is fixedly connected to a bottom end pad, the top inner side of the bottom end pad is movably connected to a top end pad, the top end of the top end pad is fixedly connected to a spring post, and the spring post is fixedly connected to the inner side of the bottom end of the clamping block.

[0011] As described above, the extension strip is fixed to the bottom end of the outer clamping block, the first magnetic block and the second magnetic block are magnetically connected, the second magnetic block and the first magnetic block are on the same horizontal line, and the clamping block is magnetically connected to the first connecting block through the cooperation of the first magnetic block and the second magnetic block.

[0012] As described above, the bottom gasket forms a telescopic structure with a buffer spring and a circular groove. The bottom gasket is made of rubber. The top of the bottom gasket has a hole and groove that fits with the top gasket. The bottom gasket and the top gasket are connected by a snap-fit ​​connection.

[0014] Compared with the prior art, this double-row female connector has the following advantages:

[0015] I. This utility model adopts a locking method using a first limiting strip and a second limiting strip. During plug insertion, the operator rotates the limiting strip to lock the locking block and the buckle. The left front end of the locking block has a notch that corresponds to the front end of the buckle, making the locking operation more convenient. It only requires a little force from the operator to complete. After locking, the limiting strip covers both sides of the limiting block, further enhancing the connection's firmness and effectively preventing the plug from shaking or shifting in all directions. In actual use, it can resist some external vibrations and pulling interference factors, preventing the plug from loosening or falling off due to unexpected situations. This ensures the continuity and stability of signal and power transmission, reduces the risk of equipment failure and signal interruption caused by poor connection, and ensures that the plug and socket always maintain a good contact state.

[0016] II. During the plug insertion process, as the locking block and buckle engage with the slot, the first magnetic block inside the extension strip attracts the second magnetic block outside the first connecting block. The magnetic attraction provides a guiding force for the plug insertion, making the plug insertion more precise. This improves the accuracy and efficiency of the plug-to-female connector docking and reduces repeated plugging and unplugging and damage to the connector caused by inaccurate insertion. When the plug is inserted, the top pad at the bottom of the clamping block contacts the bottom pad first. The spring post and the buffer spring apply pressure to the top and bottom pads respectively. The buffer spring absorbs the impact force through compression, effectively alleviating the instantaneous impact force when the plug is inserted and protecting the internal parts of the connector from damage.

[0024] like Figure 1-4As shown, this utility model provides a technical solution: a double-row female connector, including a female connector body 1, a socket 101 on the top of the female connector body 1, a pin 102 fixedly connected to the bottom of the female connector body 1, a plug 103 movably connected to the top of the socket 101, first connecting blocks 2 fixedly connected to the outer surfaces of both sides of the female connector body 1, a second connecting block 201 provided on the top of the first connecting block 2, and the second connecting block 201 fixed to the outer walls of both sides of the plug 103, a placement groove 202 is provided at the center of the top of the first connecting block 2, the placement groove 20... A rotating shaft 203 is fixedly connected to the bottom inner side of component 2. The rotating shafts 203 are arranged in a set and are horizontally positioned inside the placement groove 202. A first limiting strip 204 is movably connected to the outer surface of the rotating shaft 203. A locking block 205 is fixedly connected to the top outer side of the first limiting strip 204. A second limiting strip 206 is fixedly connected to the outer surface of the rotating shaft 203. A buckle 207 is fixedly connected to the top of the second limiting strip 206. The locking block 205 and the buckle 207 are positioned opposite each other, and a slot is provided on one side of the buckle 207 to fit against the outer wall of the locking block 205. The bottom end of the second connecting block 201... Clamping blocks 208 are fixedly connected to both sides. Limiting blocks 209 are fixedly connected to the inner walls of clamping blocks 208. A slot 210 is formed at the top of the limiting block 209, located between the second connecting block 201, the limiting block 209, and the clamping blocks 208 on both sides. The limiting block 209 is fixed to the bottom of the second connecting block 201 by the clamping blocks 208. The vertical thickness of the locking block 205 and the buckle 207 is less than the vertical thickness of the slot 210. An extension strip 3 is fixedly connected to the bottom of the clamping block 208. A first magnetic block 301 is fixedly connected to the inner surface of the extension strip 3. The inner surface of the first magnetic block 301 is movably connected to... A second magnetic block 302 is attached, which is fixedly connected to the top outer side of the first connecting block 2. Circular grooves 303 are provided on both sides of the top of the first connecting block 2. The circular grooves 303 are symmetrically distributed on both sides of the top of the placement groove 202. A buffer spring 304 is fixedly connected to the inner surface of the circular groove 303. A bottom end pad 305 is fixedly connected to the top outer side of the buffer spring 304. A top end pad 306 is movably connected to the top inner side of the bottom end pad 305. A spring post 307 is fixedly connected to the top of the top end pad 306. The spring post 307 is fixedly connected to the bottom inner side of the clamping block 208.

[0025] According to the overall structure of the device, when the plug 103 is inserted into the main body 1 of the female connector, the plug 103 is located above the main body 1 of the female connector. At this time, the operator moves the plug 103 downward. As the plug 103 is inserted, the second connecting blocks 201 on both sides of the plug 103 gradually approach the first connecting blocks 2 on both sides of the main body 1 of the female connector. When the second connecting blocks 201 drive the clamping blocks 208 to be above the first connecting blocks 2, the operator manipulates the first limiting strips 204 and the second limiting strips 206 at both ends to close them. As the pivot 203 begins to rotate, the top locking blocks 205 and 207 move closer together with the rotation of the limiting strips. When they approach each other, the first limiting strip 204 and the second limiting strip 206 respectively cover the two sides of the limiting block 209 and are secured to the inner wall of the clamping block 208. At the same time, the top locking blocks 205 and 207 penetrate the locking groove 210 to engage. The left front end of the locking block 205 has a notch, which corresponds to the notch at the front end of the 207. When they come into contact, the operator can achieve engagement by applying a little force. The engaging connection between the locking block 205 and the latch 207 achieves a stable connection between the plug 103 and the main body 1 of the female connector. When the locking block 205 and the latch 207 are engaged in the inner wall of the slot 210, the extension strip 3 at the bottom of the outer clamping block 208 also approaches the first connecting block 2. At this time, the first magnetic block 301 on the inner surface of the extension strip 3 attracts the second magnetic block 302 on the outer side of the first connecting block 2, generating a certain attraction force between the clamping block 208 and the first connecting block 2, providing a guiding force for the plug 103 when it is inserted. This makes the insertion of plug 103 more precise. During the insertion of plug 103, the top pad 306 at the bottom of clamp block 208 contacts the bottom pad 305 first. Spring post 307 and buffer spring 304 apply pressure to the top pad 306 and the bottom pad 305 respectively. The buffer spring 304 below the bottom pad 305 begins to be compressed. The buffer spring 304 absorbs the impact force generated when plug 103 is inserted through its own elastic deformation, thereby providing a buffering effect for plug 103 and female connector body 1.

[0026] like Figure 1-4 As shown, the second connecting block 201 is positioned directly above the first connecting block 2 via the plug 103. The first limiting strip 204 and the second limiting strip 206 are both rotatably connected to the outside of the rotating shaft 203. The locking block 205 and the buckle 207 are engaged. The first limiting strip 204 and the second limiting strip 206 are symmetrically distributed on the inner wall of the placement groove 202. The locking block 205 and the buckle 207 are engaged inside the slot 210. The first limiting strip 204 and the second limiting strip 206 cover both sides of the limiting block 209. The plug 103 forms an engaging structure with the first connecting block 2 through the cooperation between the slot 210, the locking block 205, the buckle 207 and the first limiting strip 204.

[0027] By manipulating the first limiting strip 204 and the second limiting strip 206 at both ends, the two ends are rotated about the pivot 203 and brought closer to each other. The top locking block 205 and the buckle 207 move towards the center as the limiting strips rotate. When they are close, the first limiting strip 204 and the second limiting strip 206 cover the two sides of the limiting block 209 and are locked in place on the inner wall of the clamping block 208. At the same time, the top locking block 205 and the buckle 207 pass through the locking groove 210 and engage. The left front end of the locking block 205 has a notch, which corresponds to the notch at the front end of the buckle 207. When they come into contact, the operator can apply a little force to achieve the engagement connection between the locking block 205 and the buckle 207, thereby achieving a stable connection between the plug 103 and the main body 1 of the female connector.

[0028] like Figure 1-4 As shown, the extension strip 3 is fixed to the bottom of the outer clamping block 208. The first magnetic block 301 and the second magnetic block 302 are magnetically connected. The second magnetic block 302 and the first magnetic block 301 are on the same horizontal line. The clamping block 208 is magnetically connected to the first connecting block 2 through the cooperation of the first magnetic block 301 and the second magnetic block 302. The bottom end pad 305 forms a telescopic structure with the circular groove 303 through the buffer spring 304. The bottom end pad 305 is made of rubber. 5. A slot is provided at the top to fit the top gasket 306. The bottom gasket 305 and the top gasket 306 are connected by a snap-fit. The outer surface of the bottom end of the top gasket 306 is in close contact with the inner surface of the top end of the bottom gasket 305. The spring post 307, the buffer spring 304 and the circular groove 303 are set on the same vertical center line. The top gasket 306 is fixed to the bottom end of the clamping block 208 by the spring post 307. The bottom horizontal line of the top gasket 306 is lower than the bottom horizontal line of the clamping block 208.

[0029] The first magnetic block 301 on the inner surface of the extension strip 3 attracts the second magnetic block 302 on the outer side of the first connecting block 2, so that the clamping block 208 and the first connecting block 2 have a certain attraction force, which provides a guiding force for the plug 103 when it is inserted, making the insertion of the plug 103 more accurate. During the insertion of the plug 103, the top pad 306 at the bottom of the clamping block 208 contacts the bottom pad 305 first. The spring post 307 and the buffer spring 304 apply pressure to the top pad 306 and the bottom pad 305 respectively. The buffer spring 304 below the bottom pad 305 begins to be compressed. The buffer spring 304 absorbs the impact force generated when the plug 103 is inserted through its own elastic deformation, thereby providing a buffering effect for the plug 103 and the main body 1 of the female connector.

[0030] Working principle: When the device is in use, the socket 101 at the top of the female connector body 1 is exposed, and the pin 102 at the bottom is used to connect to the circuit board. When the plug 103 is inserted into the female connector body 1, the plug 103 is located above the female connector body 1. At this time, the operator moves the plug 103 downward. As the plug 103 is inserted, the second connecting blocks 201 on both sides of the plug 103 gradually approach the first connecting blocks 2 on both sides of the female connector body 1. When the second connecting blocks 201 drive the clamping blocks 208 to be above the first connecting blocks 2, the operator manipulates the first limiting strips 204 and the second limiting strips 206 at both ends to close them. As the pivot 203 begins to rotate, the top locking blocks 205 and buckles 207 move closer to each other as the limiting strips rotate. When they are close, the first limiting strip 204 and the second limiting strip 206 cover the two sides of the limiting block 209 respectively and are locked in place on the inner wall of the clamping block 208. At the same time, the top locking blocks 205 and buckles 207 pass through the locking groove 210 to engage. The left front end of the locking block 205 has a notch, which corresponds to the notch at the front end of the buckle 207. When they come into contact, the operator can apply a little force to achieve the engagement connection between the locking blocks 205 and the buckles 207, thereby achieving a stable connection between the plug 103 and the main body 1 of the female connector.

[0031] When the locking block 205 and the buckle 207 are engaged in the inner wall of the slot 210, the extension strip 3 at the bottom of the outer clamping block 208 also approaches the first connecting block 2. At this time, the first magnetic block 301 on the inner surface of the extension strip 3 and the second magnetic block 302 on the outer side of the first connecting block 2 attract each other, so that the clamping block 208 and the first connecting block 2 generate a certain attraction force, which provides a guiding force for the plug 103 when it is inserted, making the insertion of the plug 103 more accurate. During the insertion of the plug 103, the top pad 306 at the bottom of the clamping block 208 contacts the bottom pad 305 first. The spring post 307 and the buffer spring 304 apply pressure to the top pad 306 and the bottom pad 305 respectively. The buffer spring 304 below the bottom pad 305 begins to be compressed. The buffer spring 304 absorbs the impact force generated when the plug 103 is inserted through its own elastic deformation, thereby providing a buffering effect for the plug 103 and the main body 1 of the female connector.
