Figure 2This utility model provides a schematic diagram of the structure of a pull rod, actuator, switch plastic, and switch terminal in a card slot connector. Figure 3 This is a schematic diagram of the structure of a positioning element in a card slot connector provided by an embodiment of the present invention. Figure 4 This is a schematic diagram of the structure of the housing in a card slot connector provided by an embodiment of the present invention. Figure 5 This is a schematic diagram of the structure of a support arm in a card slot connector provided by an embodiment of the present invention. Figure 6 This is a schematic diagram of the structure of an actuator in a card slot connector according to an embodiment of the present invention. The card slot connector provided in this embodiment includes a housing 1, a support arm 2, an actuator 3, a positioning element 4, and a pull rod 5. The support arm 2 is formed by folding back the housing 1. The actuator 3 includes a first end 31, a second end 32, and a connecting portion 33. The connecting portion 33 is connected to the first end 31 and the second end 32 respectively. The positioning element 4 passes through the housing 1, the connecting portion 33, and the support arm 2 in sequence. The pull rod 5 has a limiting groove 51, and the first end 31 is inserted into the limiting groove 51.

[0032] In the embodiment of this utility model, the X-axis, Y-axis, and Z-axis directions of the card slot connector are described below. Figure 1 As shown, the support arm 2 and the housing 1 can be integrally formed, and the positioning component 4 includes rivets.

[0033] The actuator 3 is connected to the first end 31 and the second end 32 via the connecting part 33, and can rotate under the drive of the pull rod 5. The positioning part 4 passes through the housing 1, the connecting part 33 of the actuator 3 and the support arm 2 in sequence to position the connecting part 33 of the actuator 3. The positioning part 4 not only enables the actuator 3 to be stably fixed on the connector, but also increases the contact area between the positioning part 4 and the support arm 2 and the housing 1 by passing through the support arm 2 and the housing 1, effectively preventing the positioning part 4 from jamming due to uneven force.

[0034] The pull rod 5 is provided with a limiting groove 51 that cooperates with the first end 31 of the actuator 3, so that the pull rod 5 can drive the actuator 3 to rotate around the positioning member 4.

[0035] In this embodiment, a support arm 2 is formed by folding back on the housing 1. A positioning member 4 sequentially passes through the housing 1, the connecting portion 33 of the actuator 3, and the support arm 2. The first end 31 of the actuator 3 is inserted into the limiting groove 51 of the pull rod 5. This folding of the support arm 2 on the housing 1 creates a space for placing the connecting portion 33 of the actuator 3. The pull rod 5 can drive the actuator 3 to rotate around the positioning member 4. Simultaneously, the positioning member 4, passing through the support arm 2 and the housing 1, increases the contact area between the positioning member 4 and both the support arm 2 and the housing 1, effectively preventing the positioning member 4 from jamming due to uneven force distribution. This ensures uniform force distribution at the riveting points, improving the overall stability and reliability of the connector. Thus, the technical effect of improving stability and reliability is achieved.

[0036] In one embodiment, the support arm 2 includes a first extension 21 and a second extension 22. The first extension 21 extends from the housing 1 towards the Z-axis, and the second extension 22 extends from the first extension 21 towards the X-axis or Y-axis. The second extension 22 protrudes towards the housing 1, and the positioning member 4 passes through the second extension 22. The first extension 21 and the second extension 22 can be integrally formed to form the support arm 2. The first extension 21 and the second extension 22 of the support arm 2 together constitute a folded space for placing the connecting part 33 of the actuator 3. Because the second extension 22 protrudes towards the housing 1, the positioning member 4 can contact the support arm 2 more tightly when it passes through, which helps to increase the contact area between the positioning member 4 and the support arm 2. This not only enhances the stability of the positioning member 4 but also effectively prevents the positioning member 4 from jamming due to uneven force.

[0037] As one embodiment, the card holder connector provided by this utility model further includes a boss portion 11, which protrudes from the housing 1 towards the second extension section 22. A first through hole 111 is provided on the boss portion 11, a second through hole 221 is provided on the second extension section 22, and a third through hole 331 is provided on the connecting portion 33. The positioning member 4 passes through the first through hole 111, the third through hole 331, and the second through hole 221 sequentially, and the connecting portion 33 rotates around the positioning member 4. The boss portion 11 provides additional support points for the positioning member 4, which helps to enhance the stability of the positioning member 4. Simultaneously, after the positioning member 4 passes through the first through hole 111, the third through hole 331, and the second through hole 221 sequentially, the contact area between the positioning member 4 and the housing 1, the connecting portion 33, and the support arm 2 is increased. This not only improves the overall strength of the connector but also effectively avoids jamming of the positioning member 4 due to uneven force, thereby improving the stability and reliability of the card holder connector. When one end of the positioning member 4 is installed to the boss portion 11 and the other end of the positioning member 4 is installed to the second extension section 22, the two ends of the positioning member 4 are in contact with the boss portion 11 and the second extension section 22 respectively. This helps to increase the contact area of ​​the two ends of the positioning member 4, avoids the phenomenon of the positioning member 4 getting stuck due to uneven force, and achieves uniform force on the riveting point.

[0038] In one embodiment, a through groove 211 is provided in the first extension 21, and the projection of the through groove 211 along the X-axis onto the connecting portion 33 is at least partially located on the connecting portion 33. The through groove 211 allows the connecting portion 33 to have greater flexibility during rotation. At the same time, the through groove 211 helps to reduce the contact area between the connecting portion 33 and the first extension 21, thereby reducing the friction of the connecting portion 33 during rotation. This not only improves the rotation efficiency of the connector but also helps to extend the service life of the connector.

[0039] As one embodiment, the card holder connector provided by this utility model further includes a stop section 6, which extends from the first extension section 21 in the X-axis direction. The stop section 6, the first extension section 21, and the housing 1 enclose a stop space 61 for the insertion of the pull rod 5. The stop section 6 provides additional support and limiting function for the pull rod 5. When the pull rod 5 is inserted into the stop space 61, the range of motion of the pull rod 5 is limited, ensuring that the pull rod 5 can stably drive the actuator 3 to rotate.

[0040] In one embodiment, the support arm 2 can be bent from the housing 1 toward the Z-axis direction, and the support arm 2 extends along the X-axis direction, so that a U-shaped space for placing the connecting part 33 of the actuator 3 is formed between the support arm 2 and the housing 1.

[0041] In one embodiment, the first end 31 includes a bent section 311 and a plug-in section 312. The bent section 311 bends from the connecting portion 33 toward the housing 1, and the plug-in section 312 connects to the bent section 311 and can be inserted into the limiting groove 51. The bent section 311 and the plug-in section 312 allow the first end 31 to better fit with the limiting groove 51. When the plug-in section 312 is inserted into the limiting groove 51, the bent section 311 provides an additional support point, which helps to enhance the connection stability between the first end 31 and the pull rod 5, and improve the overall strength of the connector. At the same time, due to the tight fit between the plug-in section 312 and the limiting groove 51, it also ensures that the pull rod 5 can stably drive the actuator 3 to rotate.

[0042] In one embodiment, a limiting platform 321 protruding towards the housing 1 is provided on the second end 32. The connector provided in this embodiment also includes a spring arm 7, which is disposed on the housing 1. The spring arm 7 is bent in the Z-axis direction and extends towards the support arm 2. The projection of the limiting platform 321 onto the spring arm 7 along the direction towards the spring arm 7 is located on the spring arm 7. The cooperation between the limiting platform 321 and the spring arm 7 can limit the second end 32 of the actuator 3, preventing the actuator 3 from accidentally moving or falling off in a non-operating state. Simultaneously, the spring arm 7 provides additional support and limiting points for the limiting platform 321, which helps enhance the stability of the actuator 3. When the actuator 3 rotates around the positioning member 4 under the drive of the pull rod 5, the interaction between the limiting platform 321 and the spring arm 7 ensures that the movement trajectory of the actuator 3 is stable and controllable. This not only improves the overall stability of the connector but also helps prevent the positioning member 4 from jamming due to uneven force.

[0043] In one embodiment, the card holder connector provided by this utility model further includes a first limiting member 8 and a second limiting member 81. The first limiting member 8 and the second limiting member 81 are respectively connected to the housing 1. The first limiting member 8, the second limiting member 81, and the housing 1 enclose an installation space 82 extending along the X-axis direction, through which the pull rod 5 can pass. The first limiting member 8 and the second limiting member 81 provide a stable installation environment for the pull rod 5. The installation space 82 not only ensures that the pull rod 5 can move along a predetermined trajectory, but also avoids unnecessary collisions or interference between the pull rod 5 and the housing 1 or other components during movement, which is beneficial to improving the overall reliability of the connector and extending its service life.

[0044] As one embodiment, the card slot connector provided by this utility model further includes a switch plastic 9 and a switch terminal 91. The switch plastic 9 is connected to the housing 1 and is used to hold the switch terminal 91. The switch plastic 9 and the housing 1 enclose a groove 92, which can be used to place the second end 32. The switch plastic 9 can also provide stable support and fixing points for the second end 32. The groove 92 can ensure that the second end 32 can be accurately placed in the predetermined position and prevent the second end 32 from shaking or falling off during movement or operation, so that the actuator 3 can accurately respond to the pull rod 5 to rotate.
