Description

Technical Field

[0001] This disclosure relates to the field of electronic communication technology, and in particular to a connector assembly and an electronic device. Background Technology

[0002] SIM (Subscriber Identity Module) cards are widely used in mobile phones and other electronic devices.

[0003] In related technologies, the SIM card connector of electronic devices often includes a card tray and a card socket. When the card tray containing the SIM card is inserted into the card socket, the terminal array in the card socket will connect with the contacts on the SIM card to realize the connection between the SIM card and the circuit board in the electronic device.

[0004] When no SIM card is placed in the card tray, there is a gap between the terminal array and the card tray. When the device is in an electrostatic environment, external static electricity will be conducted to the card tray. Since the voltage of static electricity is relatively large, the static electricity will break down the gap and flow to the terminal array. When the static current flows from the non-grounded terminals in the terminal array to the circuit board, it may cause damage to the circuit board. Utility Model Content

[0005] This disclosure provides a connector assembly and an electronic device, which can solve the aforementioned technical problems existing in related technologies. The technical solution is as follows:

[0013] In some possible implementations, the housing assembly has a mounting hole for accommodating the contact portion when it deforms.

[0014] In some possible implementations, the housing assembly includes a circuit board and a first insulating plate, a portion of which is opposite to the circuit board and another portion protrudes toward the circuit board;

[0015] The first terminal array portion is embedded within the first insulating plate, and the pins of each terminal in the first terminal array protrude from the bottom end of the portion of the first insulating plate that protrudes toward the circuit board and are connected to the circuit board.

[0016] In some possible implementations, the housing assembly further includes a metal cover that covers the outside of the first insulating plate and is connected to the first grounding terminal, and the metal cover is connected to the circuit board.

[0017] In some possible implementations, the sidewall of the metal cover has a resilient arm, and the sidewall of the card tray has a limiting groove for locking the resilient arm when the card tray is fully inserted into the receiving groove.

[0018] In some possible implementations, the first grounding terminal has a resilient tab that protrudes from the outer surface of the housing assembly and is used to elastically abut against the grounding component of the electronic device.

[0019] In some possible implementations, the support plate is made of metal.

[0020] In some possible implementations, the connector assembly further includes a second terminal array fixed to the housing assembly and partially located within the receiving groove.

[0024] The beneficial effects of the technical solution provided in this disclosure include at least the following:

[0025] The first grounding terminal can contact the support plate or the SIM card placed on the support plate. When external static electricity is conducted to the card tray, the static electricity on the card tray will flow to the support plate made of conductive material, and further to the first grounding terminal, thereby discharging the static electricity from the connector assembly. Thus, the static electricity on the card tray will not flow to the circuit board from the non-grounded terminals in the first terminal array, thereby reducing the possibility of damage to the circuit board due to static electricity.

[0039] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] This disclosure provides a connector assembly. (In conjunction with...) Figures 1 to 3 As shown, the connector assembly includes a housing assembly 1, a first terminal array 3, and a tray 2. The housing assembly 1 has a receiving groove 101, and the tray 2 is fixed within the receiving groove 101. The tray 2 has a support plate 22, which is made of a conductive material. The first terminal array 3 is fixed to the housing assembly 1 and partially located within the receiving groove 101. The first terminal array 3 includes a first ground terminal 31, which contacts the support plate 22.

[0042] Using the connector assembly provided in this embodiment, the first grounding terminal 31 contacts the support plate 22 or the SIM card placed on the support plate. When external static electricity is conducted to the card tray 2, the static electricity on the card tray 2 flows to the support plate 22 made of conductive material, and further to the first grounding terminal 31, thereby discharging the static electricity from the connector assembly. Therefore, the static electricity on the card tray 2 will not flow from the non-grounded terminals in the first terminal array 3 to the circuit board 11, thus reducing the possibility of damage to the circuit board 11 due to static electricity.

[0043] The phrase "the first grounding terminal 31 is in contact with the support plate 22" means that when the first grounding terminal 31 is not in contact with the SIM card, the first grounding terminal 31 will be in contact with the support plate 22.

[0044] Combination Figures 1 to 3As shown, the card tray 2 also includes a bracket 21, which surrounds and is connected to the support plate 22, and protrudes from the first surface 221 of the support plate 22 to form a first card slot 201 for receiving a SIM card. In use, the first terminal array 3 is fixed to the housing assembly 1 for connecting with the contacts of the SIM card located in the first card slot 201 to transmit electrical signals.

[0045] When no SIM card is placed in the first card slot 201, the first grounding terminal 31 will contact the support plate 22. When a SIM card is placed in the first card slot 201, the following possibilities exist: If the first card slot 201 can only accommodate one type of SIM card, the first grounding terminal 31 will contact the SIM card when a SIM card is placed in the first card slot 201; if the first card slot 201 can accommodate multiple types of SIM cards, the first grounding terminal 31 may contact the SIM card when one type of SIM card is placed in the first card slot 201, or the SIM card of that type may not fill the first card slot 201, thus causing the first grounding terminal 31 to contact the support plate 22.

[0046] Thus, regardless of whether a SIM card is contained in the first card slot 201, when external static electricity is conducted to the card tray 2, the static electricity on the card tray 2 will flow to the support plate 22 made of conductive material and then to the first grounding terminal 31, thereby discharging the static electricity from the connector assembly.

[0047] The support 21 is made of an insulating material. For example, the support 21 can be made of latex material.

[0048] like Figure 5 As shown, in some possible implementations, the first grounding terminal 31 includes a connecting portion 311 and a contact portion 312 connected together. The connecting portion 311 is embedded in the housing assembly 1, and the contact portion 312 protrudes relative to the connecting portion 311 and contacts the support plate 22.

[0049] Thus, by embedding the connecting portion 311 within the housing assembly 1, the connection portion 311 can be prevented from detaching from the housing assembly 1, thereby ensuring the stability of the first grounding terminal 31 during use. Furthermore, the contact portion 312 protrudes relative to the connecting portion 311, thereby extending into the receiving groove 101 and contacting the SIM card or support plate 22.

[0050] Optionally, part of the connecting portion 311 is in the shape of a rectangular ring, and the two ends of the contact portion 312 are respectively connected to the two opposite sides of the rectangular ring.

[0051] In some possible implementations, the first grounding terminal 31 abuts against the support plate 22.

[0052] This reduces the possibility of the first grounding terminal 31 detaching from the support plate 22, thereby ensuring stable contact between the first grounding terminal 31 and the support plate 22. Consequently, static electricity on the support plate 22 can be reliably guided to the first grounding terminal 31.

[0053] like Figure 5 As shown, in some possible implementations, the contact portion 312 is an elastic structure.

[0054] Thus, when a SIM card is placed in the first card slot 201, the contact portion 312 undergoes elastic deformation, enabling it to connect with the contacts on the SIM card. When the SIM card is removed, the contact portion 312 abuts against the support plate 22 under the elastic action, thereby ensuring the grounding function of the first grounding terminal 31.

[0055] Optionally, the elastic structure is a metal spring, so that the grounding requirement of the first grounding terminal 31 can be achieved through a simple structure.

[0056] like Figure 5 As shown, in some possible implementations, the housing assembly 1 has a mounting hole 102 for accommodating the contact portion 312 when it deforms.

[0057] Thus, when the contact portion 312 undergoes elastic deformation, for example when a SIM card is installed in the first card slot 201, the contact portion 312 will undergo elastic deformation in a direction away from the support plate 22. At this time, the mounting hole 102 can accommodate the deformed part of the contact portion 312, thereby reducing the possibility that the contact portion 312 will be squeezed against the housing assembly 1 or even undergo plastic deformation during deformation, thereby improving the stability of the metal spring during use.

[0058] like Figure 6 As shown, in some possible implementations, the housing assembly 1 includes a circuit board 11 and a first insulating plate 12, a portion of which faces the circuit board 11 and another portion protrudes toward the circuit board 11. A first terminal array 3 is partially embedded in the first insulating plate 12, and the pins of each terminal in the first terminal array 3 protrude from the bottom end of the portion of the first insulating plate 12 that protrudes toward the circuit board 11 and are connected to the circuit board 11.

[0059] Thus, the pins of each terminal in the first terminal array 3 are connected to the circuit board 11, thereby enabling the signal transmission and grounding effect of the first terminal array 3. In this process, the first insulating plate 12 can protect the first terminal array 3, thereby reducing the possibility of external electrostatic interference to the non-grounded terminals in the first terminal array 3, and reducing the possibility of interconnection between the terminals in the first terminal array 3. Therefore, the stability of the first terminal array 3 during signal transmission can be guaranteed.

[0060] like Figure 6 As shown, in some possible implementations, the housing assembly 1 further includes a metal cover 13, which covers the outside of the first insulating plate 12 and is connected to the first grounding terminal 31. The metal cover 13 is also connected to the circuit board 11.

[0061] Thus, the metal cover 13 can support the first insulating plate 12, reducing the possibility of damage to the first insulating plate 12 when the first terminal array 3 deforms. Furthermore, the metal cover 13 is connected to the first grounding terminal 31 and the circuit board 11 respectively, thereby conducting static electricity on the first grounding terminal 31 to the grounding circuit on the circuit board 11, and thus discharging static electricity from the connector assembly.

[0062] like Figure 4 As shown, in some possible implementations, the sidewall of the metal cover 13 has an elastic arm 131, and the sidewall of the card holder 2 has a limiting groove 203, which is used to lock the elastic arm 131 when the card holder 2 is fully inserted into the receiving groove 101.

[0063] Thus, when the card tray 2 is fully inserted into the receiving groove 101, the elastic arm 131 enters the limiting groove 203, thereby locking the card tray 2 and reducing the possibility of the card tray 2 coming off during the use of the connector assembly, thereby improving the stability of the connector assembly during use.

[0064] Optionally, combined Figure 4 , Figure 6 As shown, the housing assembly 1 also includes a rotating block 15 and a push rod 16. The rotating shaft of the rotating block 15 is engaged with the metal cover 13, and the rotating block 15 can rotate around the rotating shaft. One end of the rotating block 15 is engaged with the push rod 16, and the other end is located in the receiving groove 101. Figure 4 In the state shown, the end of the rotating block 15 away from the push rod 16 can avoid the card holder 2. Figure 3 In the state shown, push rod 16 is pushed and drives rotating block 15 to rotate, so that the end of push rod 16 that moves away from rotating block 15 pushes card holder 2, causing card holder 2 to move away from card slot.

[0065] In this way, the card holder 2 can be unlocked by the cooperation of the rotating block 15 and the push rod 16, so that the card holder 2 can be easily installed or removed.

[0066] In some possible implementations, the first insulating plate 12 is formed by injection molding.

[0067] Thus, during the molding process of the first insulating plate 12, the liquid material can be used to encapsulate the first terminal array 3. After the material is cured, the first insulating plate 12 can be obtained, thereby enabling the first insulating plate 12 to protect the first terminal array 3.

[0068] Optionally, the first insulating plate 12 is made of silicone.

[0069] Combination Figure 1 , Figure 4 As shown, in some possible implementations, the first grounding terminal 31 has an elastic tab 313 that protrudes from the outer surface of the housing assembly 1 and is used to elastically abut against the grounding component of the electronic device.

[0070] Thus, by elastically abutting against the grounding component of the electronic device through the elastic tab 313, static electricity can be directly released to the grounding component, thereby further ensuring that the first grounding terminal 31 can discharge static electricity to the connector assembly, and thus ensuring the reliability of the static electricity release of the first grounding terminal 31.

[0071] In some possible implementations, the support plate 22 is made of metal.

[0072] In this way, the structural strength of the card holder 2 can be improved while meeting the conductivity requirements of the support plate 22, thereby increasing the service life of the card holder 2.

[0073] Combination Figures 2 to 4 As shown, in some possible implementations, the connector assembly further includes a second terminal array 4, which is fixed to the housing assembly 1 and partially located within the receiving groove 101. The second terminal array 4 is located on the side of the support plate 22 away from the first terminal array 3. The second terminal array 4 includes a second ground terminal 41, which contacts the support plate 22.

[0074] Thus, the second grounding terminal 41 will contact the support plate 22 or the SIM card. When external static electricity is conducted to the card tray 2, the static electricity on the card tray 2 will flow to the support plate 22 made of conductive material, and further to the second grounding terminal 41, thereby discharging the static electricity from the connector assembly. As a result, static electricity will not flow from the non-grounded terminals in the second terminal array 4 to the circuit board 11, thereby reducing the possibility of damage to the circuit board 11 due to static electricity.

[0075] Combination Figures 2 to 4 As shown, the bracket 21 also protrudes from the second surface 222 of the support plate 22 to form a second card slot 202 for receiving a SIM card. The second surface 222 is the surface of the support plate 22 facing away from the first surface 221. The second terminal array 4 is used to connect with the contacts of the SIM card located in the second card slot 202, and the second ground terminal 41 is used to abut against the support plate 22 when no SIM card is placed in the second card slot 202.

[0076] In this way, the connector assembly can hold two SIM cards. When the two SIM cards are placed into the first card slot 201 and the second card slot 202 respectively, the two SIM cards are located on both sides of the support plate 22 and are stacked with the support plate 22. In this way, the connector assembly can accommodate two SIM cards while reducing its size, which is beneficial to the thinning and lightening of electronic devices.

[0077] like Figure 6 As shown, in some possible implementations, the housing assembly 1 includes a circuit board 11 and a second insulating plate 14, which is stacked on top of the circuit board 11. A second terminal array 4 is partially embedded in the second insulating plate 14, and the pins of each terminal in the second terminal array 4 protrude from the surface of the second insulating plate 14 near the circuit board 11 and are connected to the circuit board 11.

[0078] Thus, the pins of each terminal in the second terminal array 4 are connected to the circuit board 11, thereby enabling the signal transmission and grounding effect of the second terminal array 4. In this process, the second insulating plate 14 can protect the second terminal array 4, reduce the possibility of external electrostatic interference to the non-grounded terminals in the second terminal array 4, and reduce the possibility of short circuits in the terminals in the second terminal array 4. Therefore, the stability of the second terminal array 4 during signal transmission can be guaranteed.

[0079] Based on the same concept, this disclosure also provides an electronic device, which includes the connector assembly provided above.

[0080] Alternatively, the electronic device may be, for example, but not limited to, a smartphone or a tablet computer, and this disclosure does not impose any limitations on this.

[0081] like Figure 4 As shown, the card tray 2 also includes a sealing ring 23 and a cover plate 24. The sealing ring 23 is fitted onto the bracket 21 and is used to seal the card tray 2 at the card slot opening of the electronic device. The cover plate 24 is used to block the card slot opening.

[0082] Thus, the sealing ring 23 and the cover plate 24 can improve the sealing performance of the electronic device at the slot, and the cover plate 24 can also seal the slot opening, thereby improving the aesthetics of the electronic device.

[0083] Optionally, the connecting assembly also includes a switch element located at the bottom of the receiving groove 101. The switch element includes a conductive part and a trigger part. The conductive part is connected to the circuit board 11, and the trigger part is elastic. When the card holder 2 has not entered the receiving groove 101, the trigger part abuts against the conductive part. After the card holder 2 has fully entered the receiving groove 101, the trigger part is squeezed by the card holder 2 to disconnect from the conductive part.

[0084] Thus, when the SIM card tray 2 is not in the receiving slot 101, the switch is closed, and the circuit board 11 can send a signal to read the SIM card; after the SIM card tray 2 leaves the receiving slot 101, the switch is opened, and the circuit board 11 can send a signal to stop reading the SIM card.

[0085] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0086] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this disclosure. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0087] In the description of this disclosure, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this disclosure and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this disclosure; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0088] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
