The cover 13 is connected to the first arm 11, and the cover 13 can cover at least a portion of the second arm 12 and at least functions to apply a pressing force to the second arm 12 toward the card socket 20 when the card holder 200 is inserted into the card socket 20.

In the detection switch 10 of the embodiment of the present application, the cover 13 can cover at least a portion of the second arm 12, and at least when the card holder 200 is inserted into the card socket 20, the cover 13 can apply a pressing force to the second arm 12 toward the card socket 20, so that a tilting amplitude of the second end 122 of the second arm 12 when the card holder 200 is inserted into the card socket 20 is limited, so that a scratch does not occur between the card holder 200 and the second arm 12 when the card holder 200 is inserted into the card socket 20, the detection switch 10 is not easily damaged, and a service life of the detection switch 10 is prolonged.

Specifically, referring to fig. 1 to 3, the detection switch 10 may be fixedly installed on the card socket 20, and detect whether the card holder 200 is inserted into the card socket 20, so that the card socket 20 can implement a hot plug function. Specifically, the detection switch 10 may include a first arm 11, a second arm 12, and a cover 13.

The first arm 11 may be mounted to the socket 20, for example, the first arm 11 may be clamped to the socket 20, the first arm 11 may be welded to the socket 20, or the first arm 11 may be connected to the socket 20 by injection molding, which is not listed here. The first arm 11 may be made of a conductive material, for example, a metal conductive material such as iron, aluminum, copper, alloy, etc. The first arm 11 may have a substantially rectangular shape or an irregular shape, without limitation.

The second arm 12 may be connected to the first arm 11, for example the second arm 12 may be fixedly connected to the first arm 11. A portion of the second arm 12 may be mounted to the cartridge 20, for example, a portion of the second arm 12 may be mounted to the cartridge 20, a portion of the second arm 12 may be welded to the cartridge 20, and so on, to name but a few. The second arm 12 may be made of a conductive material, for example, a metal conductive material such as iron, aluminum, copper, alloy, etc.

The second arm 12 may include a first end 121 and a free second end 122 opposite the first end 121, the first end 121 may be connected to the first arm 11, and the second end 122 may be rotatable with respect to the first end 121. The first end 121 may be a fixed end, which is fixed when the card holder 200 is inserted and pulled out, and the second end 122 may be a free end, which is capable of moving relative to the first end 121, and referring to fig. 3 and 4, when the card holder 200 is not inserted or the card holder 200 is not inserted in place, the second end 122 may be connected to the conductive terminal 30; during the process of inserting the card holder 200 into the card socket 20, the card holder 200 can abut against the second arm 12, the second arm 12 is elastically deformed, and the second end 122 can move along the inserting direction X1 of the card holder 200 to be disconnected from the conductive terminal 30, as shown in fig. 5; when the card holder 200 is pulled out of the card holder 20, the card holder 200 no longer abuts against the second arm 12, and the second arm 12 can recover its deformation under the elastic restoring force and move along the pulling direction X2 of the card holder 200, so that the second end 122 is reconnected with the conductive terminal 30. Accordingly, the detection switch 10 can recognize whether the card holder 200 is inserted into the card socket 20 by detecting a signal change of the switch 10.

It should be noted that one of the second arm 12 and the conductive terminal 30 is connected to a high level, and the other of the second arm 12 and the conductive terminal 30 is connected to a low level, so that the detection switch 10 can detect the insertion and extraction of the card holder 200 according to the voltage variation. For example, the second arm 12 may be connected to a high level, and the conductive terminal 30 may be connected to a low level; alternatively, the second arm 12 is connected to the low level and the conductive terminal 30 is connected to the high level.

Referring to fig. 1, the second arm 12 may include a fixing portion 123, a first connecting portion 124, a supporting portion 125, a second connecting portion 126 and a contact portion 127, which are connected in sequence. The fixing portion 123 may be mounted on the card socket 20, the abutting portion 125 may be used for abutting against the card holder 200, the contact portion 127 may be used for contacting with the conductive terminal 30, the first connecting portion 124 may connect the fixing portion 123 and the abutting portion 125, the second connecting portion 126 may connect the abutting portion 125 and the contact portion 127, the fixing portion 123 may be located at the first end 121, and the contact portion 127 may be located at the second end 122.

The fixing portion 123, the first connecting portion 124, the abutting portion 125, the second connecting portion 126 and the contact portion 127 can be formed by bending the second arm 12 for multiple times, for example, the second arm 12 can be bent for the first time to form the fixing portion 123, the second arm can be bent for the second time to form the first connecting portion 124, the third arm can be bent for the abutting portion 125, and the fourth arm can be bent for the contact portion 127. The included angle between the first connecting portion 124 and the first arm 11 may be an acute angle, and the shape formed by the first connecting portion 124, the abutting portion 125 and the second connecting portion 126 may be a "V" shape, so that the card holder 200 can better abut against the abutting portion 125. The surface of the abutting portion 125 opposite to the insertion direction X1 of the card holder 200 may be a curved plane, so as to increase the abutting area between the card holder 200 and the abutting portion 125, and avoid the damage to the card holder 200 caused by the excessively sharp abutting portion 125.

With continued reference to fig. 1, the cover 13 may be connected to the first arm 11 and may be used to prevent the second arm 12 from tilting. The cover 13 may be made of a conductive material, for example, a metal conductive material such as iron, aluminum, copper, alloy, etc.; the cover 13 may be made of plastic, silicone, etc., which are not listed here.

The cover 13 may at least cover a portion of the second arm 12, the second arm 12 covered by the cover 13 may be pressed by the cover 13, and the cover 13 may limit the degree of freedom of the second arm 12 along a direction perpendicular or substantially perpendicular to the card socket 20, so that the second arm 12 is not easily tilted, and further, when the card holder 200 (shown in fig. 6) is inserted into the card socket 20 (shown in fig. 2) or the card holder 200 is pulled out of the card socket 20, the detection switch 10 is not easily scratched with the card holder 200 or other elements, that is, the detection switch 10 is not easily damaged, and the service life of the detection switch 10 may be prolonged. In one example, the cover 13 may completely cover the second arm 12; in another example, the cover 13 may partially cover the second arm 12. In the embodiment shown in fig. 1, the cover 13 may cover the contact portion 127 and a portion of the second connection portion 126.

In some embodiments, the cover 13 is angled 90 ° from the first arm 11 and the cover 13 is angled 90 ° from the second arm 12.

Specifically, the portion of the cover 13 covering the second arm 12 may include the second end 122 of the second arm 12, and when the card holder 200 is inserted into the card holder 20 or the card holder 200 is pulled out of the card holder 20, the cover 13 may press the second end 122, so that the second end 122 may not be tilted or the second end 122 may be tilted to a lesser extent. The cover 13 may include a pressing surface 131 that presses against the second arm 12, it being understood that the pressing surface 131 is opposite the second arm 12. The pressing surface 131 may contact the second arm 12, the pressing surface 131 may have a small gap with the second arm 12, the pressing surface 131 may be perpendicular to the inner surface or the outer surface of the first arm 11, and the pressing surface 131 may also be perpendicular to the inner surface or the outer surface of the second arm 12.

Referring to fig. 1 to 4, a through hole 132 may be formed in a region of the cover 13 opposite to the conductive terminal 30, and the through hole 132 may avoid the conductive terminal 30, so that the cover 13 may not contact the conductive terminal 30, thereby preventing a voltage of the detection switch 10 from changing when the card holder 200 is inserted or not inserted, and improving a detection accuracy of the detection switch 10. The through hole 132 may penetrate through the cover 13, and the lateral dimension (i.e., the x and y directions) of the through hole 132 may be greater than or equal to the lateral dimension of the conductive terminal, so that the cover 13 does not contact the conductive terminal 30. The conductive terminals 30 may or may not extend into the through holes 132, and the through holes 132 are formed to avoid the conductive terminals 30, so that the height of the cover 13 can be reduced, and the thickness of the card holder assembly 200, the card connector 300, the terminal 1000 and other products mounted with the cover 13 can be reduced.

Referring to fig. 1 again, in some embodiments, the first arm 11, the second arm 12 and the cover 13 may be an integral structure. For example, the first arm 11, the second arm 12, and the cover 13 may be integrally formed by injection molding, forging, casting, or the like; or, the first arm 11, the second arm 12 and the cover 13 may be obtained by bending the integrated structure for multiple times, for example, an integrated structure may be obtained by casting, injection molding, etc., the integrated structure may be a plate, the plate may be bent for the first time to obtain the first arm 11 and the cover 13, and the plate may be bent for the second time to form the second arm 12; alternatively, the plate may be bent for the first time to obtain the first arm 11 and the second arm 12, and then bent for the second time to obtain the cover 13. In the embodiment shown in fig. 1, the cover 13 is folded 90 ° in a first direction on the basis of the first arm 11, and the second arm 12 is folded 180 ° in a second direction on the basis of the first arm 11, the first direction being perpendicular to the second direction.

In other embodiments, two of the first arm 11, the second arm 12, and the cover 13 may be a unitary structure. For example, the first arm 11 and the second arm 12 may be integrally formed, the cover 13 may be separately formed from the first arm 11 and the second arm 12, and the cover 13 may be fixedly connected to the first arm 11 by welding, bonding, or the like. For another example, the first arm 11 and the cover 13 may be integrally formed, the second arm 12 may be separately formed from the first arm 11 and the cover 13, and the second arm 12 may be connected to the first arm 11 by welding, bonding, or the like.

The second leg 15 may be made of a conductive material, such as iron, aluminum, copper, alloy, etc., so that the second leg 15 may have a conductive function. The second solder tail 15 can also be soldered with an external power supply component or a charged component (e.g., the substrate 21 of the socket 20) to achieve electrical connection, so as to supply current to the detection switch 10. It should be noted that, the first solder leg 14 and the second solder leg 15 are both connected to a high level or a low level, and are opposite to the level of the conductive terminal 30, so that the second arm 12 is in contact with the conductive terminal 30 to generate a voltage change.
