The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 5, an embodiment of the invention discloses a card socket, which includes a housing 100, a plurality of card socket terminals 200, a shielding plate 300 and an insulating part 400.
Wherein, the housing 100 is a base component of the card socket and can provide a mounting base for other components on the card socket. The housing 100 is usually a metal housing, and the housing 100 is grounded, and in an alternative, the housing 100 is a stainless steel housing, because the stainless steel has high strength and the chemical property of the stainless steel is poor, so that the housing 100 has good corrosion resistance.

In optional scheme, cassette terminal 200 can be for preventing pin structure of bursting, prevents that pin structure of bursting can protect the card to hold in the palm not blocked or hang by the head of cassette terminal 200 to prevent that conventional cassette terminal 200 can directly withstand the card and hold in the palm and lead to the card to hold in the palm such problems such as unable normal extraction, prevent the problem of cassette terminal 200 pin of bursting promptly.
The insulation part 400 is disposed on the housing 100, and the plurality of cartridge terminals 200 are disposed on the insulation part 400 at intervals, so that the insulation part 400 can isolate the cartridge terminals 200 from the housing 100, preventing the cartridge terminals 200 from contacting the housing 100. In general, the insulating portion 400 is a plastic insulating portion, and the plastic insulating portion may be disposed on the housing 100 by injection molding. Specifically, the plurality of contact portions 210 are located on the insulating portion 400 in a direction away from the housing 100, so as to prevent the insulating portion 400 from covering the contact portions 210, which may result in that the contact portions 210 cannot contact with the signal terminals of the SIM card or the TF card, or avoid interference with the insulating portion 400 when the SIM card or the TF card is mated with the card socket terminal 200.
The shield sheet 300 is disposed on the housing 100 and electrically connected to the housing 100, such that the shield sheet 300 is grounded. Specifically, the shielding plate 300 is provided with a shielding strip 310, the shielding strip 310 is connected to the main body portion 320 of the shielding plate 300, and the shielding strip 310 is disposed opposite to the terminal connecting bridge 220. In the embodiment of the present invention, the materials of the housing 100 and the shielding plate 300 are not limited.
In the card socket disclosed by the invention, the shielding sheet 300 is arranged on the shell 100 and is electrically connected with the shell 100, so that the shielding sheet 300 is grounded, the shielding sheet 300 is provided with the shielding strip 310, the shielding strip 310 on the shielding sheet 300 is arranged opposite to the terminal connecting bridge 220 of the card socket terminal 200, so that the shielding strip 310 can realize the signal shielding effect at the terminal connecting bridge 220, thereby shielding the interference among the card socket terminals 200, further preventing the crosstalk condition of the card socket terminals 200 during signal transmission and improving the reliability of the card socket.
In the embodiment of the present invention, the housing 100 and the shield sheet 300 may be a unitary structure, however, when the cartridge terminal 200 and the insulating part 400 are provided on the housing 100 and the shield plate 300 of the integrated structure, the influence of the shielding plate 300 on the card socket terminal 200 is large, so that it is difficult for a worker to control the molding process of the card socket terminal 200, and thus, there may be a case where the holder terminal 200 is deformed or cannot be normally used after molding, and based on this, in an alternative, the housing 100 and the shielding plate 300 may be a split structure, and particularly, in the manufacturing process of the card socket, the card socket terminal 200 and the insulating part 400 are molded on the housing 100, in this molding process, the housing 100 is not provided with the shielding plate 300, so that the shielding plate 300 can be prevented from affecting the molding process of the card socket terminal 200, the worker can accurately control the forming process of the card holder terminal 200, and the reliability of the card holder terminal 200 is further improved. In addition, when the housing 100 and the shielding plate 300 are separately molded, the structures of the housing 100 and the shielding plate 300 are simple, so that the molding process of the housing 100 and the shielding plate 300 is simple, the production efficiency of the housing 100 and the shielding plate 300 can be improved, and the molding accuracy of the housing 100 and the shielding plate 300 can be ensured.
As described above, the shielding strip 310 is disposed opposite to the terminal connecting bridge 220, and specifically, the shielding plate 300 may be disposed on a side of the housing 100 facing the insulating portion 400, however, this solution causes the shielding plate 300 to be disposed on the insulating portion 400, which is inconvenient for the shielding plate 300 to be electrically connected to the housing 100, and may cause unstable grounding of the shielding plate 300, so that the shielding effect of the shielding strip 310 on the terminal connecting bridge 220 is poor. Therefore, in an alternative scheme, the contact portion 210 may be a convex contact portion, and the terminal connection bridge 220 may be located between the convex contact portion and the shielding strip 310, so that the shielding plate 300 is disposed on a surface of the housing 100 opposite to the card socket terminal 200, and thus the shielding plate 300 can be conveniently disposed on the housing 100, and the shielding plate 300 is more stably electrically connected to the housing 100, and further the shielding plate 300 is more stably grounded. Meanwhile, when the shielding plate 300 is disposed, the shielding plate 300 is only required to be disposed on the surface of the housing 100 opposite to the card socket terminal 200, and the influence on the card socket terminal 200 and the insulating part 400 is small, so that the card socket terminal 200 and the insulating part 400 which are already disposed can be prevented from being damaged when the shielding plate 300 is disposed, and the reliability of the card socket can be improved.
In general, the distance between the shielding strip 310 and the terminal connecting bridge 220 greatly affects the shielding effect of the shielding strip 310 on the terminal connecting bridge 220. Based on this, in an optional scheme, the shielding strip 310 may be bent toward a side where the terminal connection bridge 220 is located, so that a distance between the shielding strip 310 and the terminal connection bridge 220 is smaller, and thus the shielding strip 310 can better shield the terminal connection bridge 220, and further a shielding effect of the shielding strip 310 on the terminal connection bridge 220 is improved.
Specifically, the shielding strip 310 may be bent toward one side of the terminal connecting bridge 220 in a stamping manner, because the stamping process has high production efficiency and is convenient to operate, and the stamping process is easy to realize mechanization and automation, so that the shielding plate 300 can be automatically produced in a large batch, which is beneficial to reducing the cost.
In a more preferable scheme, the shielding strip 310 may include a first bending section 311, a second bending section 312 and a third bending section 313, the second bending section 312 may be connected to the main body 320 of the shielding strip 300 through the first bending section 311 and the third bending section 313, and the second bending section 312 is parallel to the terminal connecting bridge 220. In this scheme, the second bending section 312 can make the more part of the shielding strip 310 and the terminal connection bridge 220 set up relatively, so that the area on the terminal connection bridge 220 set up relatively to the shielding strip 310 is large, and the distance between the second bending section 312 and the terminal connection bridge 220 is small, so that the more part on the terminal connection bridge 220 can be shielded by the shielding strip 310, and the shielding effect of the shielding strip 310 on the terminal connection bridge 220 can be improved. Meanwhile, the main body part 320 of the shielding sheet 300 can cover part of the opening on the housing 100, so that the housing 100 and the shielding sheet 300 can better shield interference.
In order to further improve the shielding effect of the shielding strip 310 on the terminal connecting bridge 220, in an optional scheme, the distance between the shielding strip 310 and the terminal connecting bridge 220 is a first distance, and in any two adjacent card socket terminals 200, the distance between the contact portion 210 of one and the terminal connecting bridge 220 of the other is a second distance, and the second distance may be greater than the first distance.
Generally, the number of the signal terminals on the SIM card or the TF card is multiple, so that a plurality of socket terminals 200 are disposed on the socket, and the plurality of socket terminals 200 are in contact with the signal terminals on the SIM card or the TF card to read or edit information in the SIM card or the TF card. Therefore, in order to shield the terminal connecting bridges 220 on the plurality of card socket terminals 200, in an optional scheme, the number of the shielding strips 310 may be multiple, and the plurality of terminal connecting bridges 220 and the plurality of shielding strips 310 are arranged in a one-to-one correspondence manner, so that each terminal connecting bridge 220 can be shielded by the corresponding shielding strip 310, and thus each terminal connecting bridge 220 can be free from interference or does not interfere with other terminal connecting bridges 220, and further, the overall shielding effect of the card socket is better, and the reliability of the card socket can be improved.
As described above, the material of the shielding plate 300 is not limited in the embodiments of the present invention, and in an alternative, the shielding plate 300 may be a metal shielding plate, because metal generally has a better shielding function, and meanwhile, the metal shielding plate has the advantages of being easy to manufacture, low in cost, and the like. Specifically, the shielding plate 300 may also be a stainless steel shielding plate, because the strength of the stainless steel is high, and the chemical properties of the stainless steel are poor, so that the housing 100 has good corrosion resistance.
In the embodiment of the present invention, the shielding plate 300 needs to be electrically connected to the housing 100, and therefore, in an alternative scheme, the shielding plate 300 may be welded to the housing 100, and after the shielding plate 300 is welded to the housing 100, the welding position of the shielding plate 300 and the housing 100 can enable the shielding plate 300 to be electrically connected to the housing 100, and meanwhile, the welding manner is simple and easy to operate, and the welded shielding plate 300 is reliably connected to the housing 100.
In a more preferred embodiment, the shielding plate 300 and the housing 100 may be connected by laser spot welding.
Based on the card socket disclosed by the embodiment of the invention, the embodiment of the invention also discloses electronic equipment, and the disclosed electronic equipment comprises the card socket disclosed by any embodiment.
The electronic device disclosed in the embodiment of the present invention may be a smart phone, a tablet computer, an electronic book reader, a wearable device (e.g., a smart watch), a game machine, and the like.
In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.
The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art.
