Description

Technical Field

[0001] This application relates to the field of electronic technology, and more specifically to a connector, connector assembly, and electronic device. Background Technology

[0002] Multiple electronic devices can be electrically connected to each other using connectors. For example, a tablet can have a female Pogopin connector, and a keyboard compatible with the tablet can have a male Pogopin connector. The female and male Pogopin connectors are plugged into each other to establish an electrical connection between the tablet and the keyboard.

[0003] Connectors can be mounted on the housing of electronic devices. With the trend towards thinner and lighter designs for electronic devices, the housings have also become thinner, which limits the thickness of the connectors. Reducing the connector's thickness can affect the stability of its electrical connection. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a connector, a connector assembly, and an electronic device.

[0005] In a first aspect, embodiments of this application provide a connector comprising a first housing, contacts, and metal pins. At least a portion of the contacts is disposed within the first housing, and the metal pins are electrically connected to the contacts. The metal pins are located outside the first housing and are capable of being connected to electronic wires.

[0006] Based on the above solution, the connector can be directly electrically connected to the electronic lines via metal pins. This eliminates the need for a flexible circuit board to connect the connector to the electronic lines, thereby reducing the stacking thickness of the connector assembly, thus reducing the space occupied by the connector assembly, and improving current carrying capacity while reducing signal transmission impedance.

[0007] In this embodiment, the connector can be implemented as a female connector, such as a female Pogopin connector. In other embodiments, the connector can also be implemented as a male connector, such as a male Pogopin connector.

[0008] In some implementations of the first aspect, the contact includes a contact surface, and the contact surface is exposed on the side of the first housing facing a first direction; the metal pin is located on the side of the first housing facing a second direction, which is different from the first direction.

[0009] Taking the connector as a female connector as an example, when the female connector is set on the tablet, the male connector can be set on the keyboard that is compatible with the tablet. The female connector can be plugged into or magnetically connected to the male connector through the contact surface, thereby realizing the electrical connection between the tablet and the keyboard.

[0010] In some implementations of the first aspect, the first direction and the second direction are perpendicular, and the second direction is perpendicular to the thickness direction of the first housing.

[0011] In some implementations of the first aspect, the first direction and the second direction are opposite, and the second direction is parallel to the thickness direction of the first housing.

[0012] It is understood that the second direction can be different from the first direction. In this embodiment of the application, there are no specific restrictions on the setting position of the metal pin.

[0013] In some implementations of the first aspect, the size of the contact element is less than or equal to the size of the first housing along the thickness direction of the first housing.

[0014] It is understood that in the embodiments of this application, when part or all of the contact element needs to be disposed in the first housing, one side surface of the contact element may be exposed outside the first housing, and the metal pin may be located outside the first housing. This application does not impose specific restrictions on the shape of the contact element.

[0015] In some implementations of the first aspect, the aforementioned contact and the aforementioned metal pin are both made of stainless steel.

[0016] In some implementations of the first aspect, the material of the aforementioned first housing is plastic.

[0017] In some implementations of the first aspect, the connector described above is a spring pin connector.

[0018] Secondly, embodiments of this application provide a connector assembly, which includes an electronic wire and a connector as described in the first aspect and any implementation thereof, wherein the core of the electronic wire is electrically connected to a metal pin.

[0019] In some technical solutions, the connector assembly includes a connector, a flexible circuit board, and electronic wires. The thickness of the connector assembly can be the sum of the thickness of the connector, the thickness of the flexible circuit board, the thickness of the adhesive dispensing, and the thickness of the reinforcing steel sheet. In this embodiment, the connector can be directly connected to the electronic wires via metal pins; that is, the thickness of the connector assembly can include only the thickness of the connector. Thus, this embodiment reduces the thickness of the connector assembly, allowing for an increase in the thickness of the first housing as needed, thereby avoiding warping of the first housing and poor surface flatness.

[0020] It is understood that the manufacturing process of electronic wires is relatively simpler than that of flexible circuit boards, and the cost of electronic wires can be lower than that of flexible circuit boards. The connector assembly provided in this application does not include a flexible circuit board, which can reduce the cost of the connector assembly. Furthermore, the direct electrical connection between the electronic wires and the metal pins ensures the reliability of the electrical connection and the stability of signal transmission, and also reduces the impedance of signal transmission.

[0021] In some implementations of the second aspect, the aforementioned wire core is electrically connected to the metal pin by welding or bonding.

[0022] In some implementations of the second aspect, the connector assembly further includes a cover that covers the outside of the wire core and the metal pin to secure the electrical connection between the wire core and the metal pin.

[0023] In some implementations of the second aspect, the aforementioned covering is a heat shrink tubing or acetate cloth.

[0024] Thirdly, embodiments of this application also provide an electronic device, which includes a second housing and a connector assembly as described in the second aspect and any implementation thereof, wherein the connector is disposed on the second housing.

[0025] In some implementations of the third aspect, the connector contacts include contact surfaces, and these contact surfaces are exposed on the side of the first housing facing a first direction; the metal pins are located on the side of the first housing facing a second direction, which are different from the first direction; wherein the first direction is parallel to the thickness direction of the second housing.

[0026] In some implementations of the third aspect, the electronic device further includes a first circuit board, to which electronic wires in the connector assembly are electrically connected. For example, the first circuit board may be the motherboard of the electronic device. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0035] This application provides an electronic device, which may include, but is not limited to, terminal consumer electronic devices such as mobile phones, tablets, true wireless stereo (TWS) earphones, smartwatches, etc. The electronic device may also be augmented reality (AR) / virtual reality (VR) devices in the Internet of Things (IoT) field, smart bracelets and health monitoring devices, battery management systems in the automotive electronics and new energy fields, vehicle sensors or advanced driving assistance systems (ADAS), as well as related electronic devices in the fields of industrial and automation equipment, medical devices, and communications and radio frequency. This application does not impose specific limitations on these.

[0036] The following uses a tablet as an example of an electronic device.

[0037] Figure 1 The illustration shows an application scenario diagram of an embodiment of this application, specifically including a tablet 100 and a keyboard 200 that can be used with the tablet 100. (Reference) Figure 1 The tablet 100 may include a back cover 1, a frame 2, a connector 31, and a screen 4. The connector 31 may be disposed on the back cover 1. In some embodiments, the connector 31 may specifically be a female socket of a spring pin connector. Spring pin connectors have technical advantages such as small size, light weight, fast charging, and strong and stable contact, and can be used to achieve reliable electrical connections between electronic devices.

[0038] The keyboard 200 may include a connector 201 that mates with the connector 31. In some embodiments, the connector 201 may specifically be a male socket of a spring pin connector. The connector 31 and the connector 201 may be plugged into each other or magnetically connected to achieve an electrical connection between the tablet 100 and the keyboard 200.

[0039] After the tablet 100 is electrically connected to the keyboard 200, the functionality of the tablet 100 can be expanded and the input interactivity of the tablet 100 can be enhanced. For example, when the keyboard 200 is connected to an external power source, the tablet 100 can be charged through the keyboard 200, or the user can also use the keyboard 200 to perform functions such as volume adjustment, screenshotting, and text input on the tablet 100.

[0040] For ease of description later, let's first combine... Figure 1 An exemplary orientation for the flat panel 100 is defined. For example... Figure 1 As shown, the length direction of the plate 100 can be the Y direction, the width direction of the plate 100 can be the X direction, and the thickness direction of the plate 100 can be the Z direction. In some embodiments, the X, Y, and Z directions can be mutually perpendicular.

[0041] refer to Figure 1 The dimensions of the plate 100 in both the length and width directions are greater than its dimension in the thickness direction. In other words, the plate 100 has the smallest dimension in its thickness direction. In this application, the thickness of each device refers to its dimension along the Z-direction, which will not be elaborated further below.

[0042] It is understood that the perpendicularity in this application is not absolute perpendicularity. Approximate perpendicularity due to processing and assembly errors (e.g., an angle of 89.9° between two structural features) is also within the scope of perpendicularity in this application. Similarly, the parallelism in this application is not absolute parallelism. Approximate parallelism due to processing and assembly errors (e.g., an angle of 0.1° between two structural features) is also within the scope of parallelism in this application. This application does not impose specific limitations on these aspects, and the limitations on perpendicularity and parallelism will not be repeated below.

[0043] Additionally, it should be noted that the directional terms such as "upper," "lower," "left," "right," "front," "back," "top," and "bottom" used in this application are exemplary orientations of the flat plate 100, and do not indicate or imply that the device referred to must have a specific orientation. They may vary according to actual use and should not be construed as limiting this application.

[0044] The exemplary structure of connector 31 is described below. Connector 31 can be implemented as a male connector (e.g., a male connector for a Pogopin) or a female connector (e.g., a female connector for a Pogopin). It is understood that if connector 31 on the tablet 100 is implemented as a female connector, then connector 201 on the keyboard 200 can be implemented as a male connector. Similarly, if connector 31 on the tablet 100 is implemented as a male connector, then connector 201 on the keyboard 200 can be implemented as a female connector.

[0045] Figure 2A An exemplary structural diagram of connector 31 is shown. Figure 2B An exemplary structural diagram of connector 201 is shown, wherein connector 31 is a female connector socket, and connector 201 is a male connector socket that mates with connector 31. The male connector socket and the female connector socket can refer to each other as the peer connector.

[0046] Reference Figure 2A and Figure 2B Connector 31 may include a housing 312 and a contact 311 (also referred to as a metal terminal or metal PAD) disposed in the housing 312. Connector 201 may include a housing 2012 and a contact 2011 disposed in the housing 2012. Specifically, contact 311 may be embedded in the housing 312, and contact 2011 may be embedded in the housing 2012. Contact 311 and contact 2011 can contact each other to achieve electrical connection.

[0047] Specifically, both contact 311 and contact 2011 can include multiple contact surfaces. The multiple contact surfaces of contact 311 and contact 2011 can correspond one-to-one. The corresponding two contact surfaces can contact each other to achieve mutual contact between contact 311 and contact 2011.

[0048] For example, contact 311 may include a first contact surface 313a, a second contact surface 313b, and a third contact surface 313c, and contact 2011 may include a fourth contact surface 2011a, a fifth contact surface 2011b, and a sixth contact surface 2011c. The first contact surface 313a may contact the fourth contact surface 2011a, the second contact surface 313b may contact the fifth contact surface 2011b, and the third contact surface 313c may contact the sixth contact surface 2011c, so as to achieve mutual contact between contact 311 and contact 2011.

[0049] It is understandable that when connector 31 is implemented as a male connector socket, the structure of connector 31 can be referenced. Figure 2B When connector 201 is implemented as a connector female, the structure of connector 201 can be referred to Figure 2A .

[0050] Figure 3 Exemplary arrangements of connector 31 in the flat plate 100 are shown in some embodiments, specifically, Figure 3 for Figure 1 The diagram shows a cross-sectional view (AA). For ease of understanding, the following explanation uses connector 31 as an example of a female connector. In other embodiments, connector 31 can also be implemented as a male connector.

[0051] refer to Figure 3 In some embodiments, connector 31 may be disposed on the back shell 1 of plate 100. In some embodiments, the thickness direction of connector 31 may be parallel to the thickness direction of plate (i.e., Z direction).

[0052] The back cover 1 may have a through hole 11, into which the connector 31 can be inserted. Additionally, the through hole 11 exposes the surface 313 of the connector 31, through which the connector 201 on the keyboard 200 can be electrically connected to the connector 31. Therefore, the surface 313 can also be referred to as the contact surface 313 of the connector 31.

[0053] In some embodiments, connector 31 can be electrically connected to the motherboard inside the flat panel 100 via a flexible printed circuit (FPC) 32 to enable signal transmission between connector 31 and the motherboard. Connector 31 can be a connector with high current-carrying capacity.

[0054] It's understandable that with the trend towards thinner and lighter electronic devices, external devices (such as keyboards) can be used to charge tablets to improve their battery life. However, flexible circuit boards, due to size limitations, have weak heat dissipation and current carrying capacity, making them potentially difficult to apply in this charging scenario.

[0055] In other embodiments, such as Figure 3 As shown, connector 31 can be electrically connected to the motherboard (not shown) inside the flat panel 100 via flexible circuit board 32 and electronic wire 33 to realize signal transmission between connector 31 and motherboard. Among them, electronic wire 33 is a connection medium used to connect different electronic devices or electronic components inside electronic devices, and has the characteristics of strong current carrying capacity and low cost.

[0056] Specifically, the connector 31 may include a metal terminal 311 and a housing 312, with the metal terminal 311 embedded within the housing 312. In the thickness direction (i.e., the Z-direction) of the connector 31, one side surface of the metal terminal 311 may form a contact surface 313, which may be exposed from the top surface of the connector 31 to the outside of the housing 312. Furthermore, the other side surface of the metal terminal 311 may also be exposed from the bottom surface of the connector 31 to the outside of the housing 312.

[0057] The first segment 321 of the flexible circuit board 32 can be bonded (e.g., soldered) to the other side of the metal terminal 311 at the bottom of the connector 31 to form an electrical connection. The second segment 322 of the flexible circuit board 32 can be connected to one end of the electronic wire 33 (e.g., via solder layer 301), and the other end of the electronic wire 33 can be electrically connected to the motherboard. A reinforcing steel sheet 302a can be attached to the first segment 321 of the flexible circuit board 32 to support it. The reinforcing steel sheet 302a can be attached to the first segment 321 by dispensing adhesive 303a. Similarly, a reinforcing steel sheet 302b can be attached to the second segment 322 of the flexible circuit board 32 to support it. The reinforcing steel sheet 302b can be attached to the second segment 322 by dispensing adhesive 303b. In addition, adhesive 304 can be applied to the side of the electronic wire 33 facing away from the second segment 322 of the flexible circuit board 32 to fix the electronic wire 33 to the back cover 1.

[0058] It can be understood that the combination of connector 31, flexible circuit board 32 and electronic wire 33 can be called connector assembly 3. The thickness of connector assembly 3 can be the sum of the thickness of connector 31, the thickness of flexible circuit board 32, the thickness of adhesive 303 and reinforcing steel sheet 302.

[0059] To meet the requirements of thinner and lighter electronic devices, the thickness of the flat panel 100 is limited, thus restricting the thickness of the connector assembly 3. Consequently, the connector 31 has a relatively small thickness, which may result in a relatively small housing 312, making it prone to warping and causing poor surface flatness. Furthermore, when the first segment 321 of the flexible circuit board 32 is bonded to the bottom surface of the connector 31, poor contact may occur, affecting the electrical connection of the connector 31 and signal transmission between devices.

[0060] Furthermore, due to the relatively small size of the flexible circuit board 32 in the X direction, its heat dissipation and current carrying capacity are relatively weak, which may lead to lower reliability of the electrical connection and potentially affect the stability of signal transmission. Additionally, the presence of the flexible circuit board 32 between the connector 31 and the electronic wire 33 increases cost and signal transmission impedance.

[0061] To address this, embodiments of this application provide a connector assembly. The connector includes metal pins located outside the housing, through which the connector can be directly electrically connected to electronic lines. This eliminates the need for a flexible circuit board to connect the connector to the electronic lines, thereby reducing the stacking thickness of the connector assembly, i.e., reducing the space occupied by the connector assembly, and improving current carrying capacity while reducing signal transmission impedance.

[0062] The technical solution of this application is described below with reference to the accompanying drawings.

[0063] Figure 4A An exemplary arrangement of connector 31 in flat plate 100 is shown in an embodiment of this application.

[0064] Reference Figure 4A The connector assembly 3 may include a connector 31 and an electronic wire 33. The connector 31 may include a metal terminal 311 and a housing 312 (as a first housing). The metal terminal 311 may include connected contacts 311a and metal leads 311b. At least a portion of the contacts 311a may be disposed within the housing 312, for example, at least a portion of the contacts 311a may be embedded within the housing 312. The metal leads 311b may be located outside the housing 312.

[0065] When connector 31 is mounted on plate 100, metal pin 311b can be connected to electronic wire 33 and electrically connected to circuit board (e.g., motherboard (as an example of a first circuit board)) inside plate 100 through electronic wire 33 to realize signal transmission between connector 31 and motherboard.

[0066] As mentioned earlier, in Figure 3 In the example shown, connector assembly 3 includes connector 31, flexible circuit board 32, and electronic wire 33. The thickness of connector assembly 3 can be the sum of the thickness of connector 31, flexible circuit board 32, adhesive dispensing 303, and reinforcing steel sheet 302. In the embodiments of this application, as... Figure 4A As shown, connector 31 can be directly connected to electronic wire 33 via metal pin 311b. That is to say, the thickness of connector assembly 3 can include only the thickness of connector 31. Thus, the embodiment of this application reduces the thickness of connector assembly 3, thereby increasing the thickness of housing 312 of connector 31 according to actual needs, so as to avoid the problem of housing 312 warping and poor surface flatness.

[0067] In this embodiment, connector 31 is implemented as a female connector, such as a female Pogopin connector. In other embodiments, connector 31 may also be implemented as a male connector, such as a male Pogopin connector.

[0068] Connector 31 can be disposed on the back shell 1 of plate 100. The thickness direction of connector 31 can be parallel to the thickness direction of back shell 1 (i.e., the Z direction). For example, a through hole 11 can be provided on back shell 1, and connector 31 can be inserted into the through hole 11. In addition, the through hole 11 can expose the contact surface 313 of connector 31, and connector 31 can achieve electrical connection with the opposite connector through the contact surface 313.

[0069] Combination Figure 1In the application scenario shown, the through hole 11 on the back cover 1 can be located near the frame 2 to facilitate the user connecting and using the tablet 100 and the keyboard 200. Furthermore, when the keyboard 200 is connected to the tablet 100, the keyboard 200 can act as a computer stand to support the tablet 100, allowing the tablet 100 to be converted into laptop mode.

[0070] When connector 31 is inserted into through hole 11, surface 31a of connector 31 can be bonded to the inner surface of back shell 1 (as an example of a second shell) with adhesive (e.g., dispensing), thereby fixing connector 31 to back shell 1. It can be understood that the inner surface of back shell 1 is the surface of back shell 1 facing screen 4. In other embodiments, connector 31 can also be fixed by pressing it onto back shell 1 with a clamping block (not shown).

[0071] In some embodiments, to facilitate the connection between the tablet 100 and the keyboard 200, the connector 31 may also be disposed on the frame 2 of the tablet 100 (as another example of a second housing). For example, a through hole 11 may be provided on the frame 2, and the connector 31 may be inserted into the through hole 11.

[0072] In some embodiments, the frame 2 and back shell 1 of the flat plate 100 can be an integrally molded structure. For example, the materials of the back shell 1 and the frame 2 can be injection molded materials, and an integral shell is formed by injection molding. In other embodiments, the back shell 1 and the frame 2 can also be molded separately and then assembled together to form the shell of the flat plate 100.

[0073] In some embodiments, contact 311a may be electrically connected to metal pin 311b. In other embodiments, contact 311a and metal pin 311b may be an integrally formed structure.

[0074] In some embodiments, the metal terminal 311 may be made of stainless steel, copper, or other metals. That is, the contact 311a and the metal pin 311b may be made of the same material and may be stainless steel, copper, or other metals.

[0075] In the thickness direction (i.e., the Z direction) of connector 31, a contact surface 313 can be formed on one side surface of contact 311a. Contact surface 313 can be exposed from the top surface of connector 31 to the outside of housing 312. It can be understood that the top surface of connector 31 faces the positive Z direction (as a first direction), meaning that contact surface 313 is exposed on the side of housing 312 facing the positive Z direction. Furthermore, the thickness direction of housing 312 can be parallel to the Z direction.

[0076] Along the thickness direction of the housing 312, the size of the contact 311a is less than or equal to the size of the housing 312, meaning that the other surface of the contact 311a in the thickness direction of the housing 312 (i.e., the surface opposite to the contact surface 313) may not be exposed outside the housing 312. In some embodiments, refer to Figure 4B The contact 311a can be a sheet-like structure, and the thickness of the sheet-like structure can be the same as or substantially the same as the thickness of the metal pin.

[0077] It is understood that when the connector 31 is disposed on the back shell 1 of the flat plate 100, the thickness direction of the connector 31, the thickness direction of the shell 312 and the thickness direction of the back shell 1 can all be parallel to the thickness direction of the flat plate 100 (i.e., the Z direction).

[0078] Continue to refer to Figure 4A The contact surface 313 and the surface 31b of the housing 312 may be on the same plane (a plane perpendicular to the Z direction, i.e., the XY plane). In some embodiments, the contact surface 313 and the surface 31b of the housing 312 may not be on the same plane, that is, at least a portion of the contact member 311a may protrude from the surface 31b of the housing 312 along the positive Z direction.

[0079] It is understood that in the embodiments of this application, when part or all of the contact 311a needs to be disposed in the housing 312, one side surface of the contact 311a can be exposed outside the housing 312, and the metal pin 311b connected to the contact 311a can be located outside the housing 312. This application does not impose specific restrictions on the shape of the contact 311a.

[0080] The metal pin 311b can be located on the side of the housing 312 facing the negative X direction (as an example of a second direction), meaning the second direction can be perpendicular to the thickness direction of the housing 312 (i.e., the Z direction). In other words, the metal pin 311b can extend from the surface 31c of the housing 312 facing the negative X direction. In other embodiments, the metal pin 311b can be located on the side of the housing 312 facing the negative Z direction (as another example of a second direction), meaning the second direction can also be opposite to the first direction. That is, the metal pin 311b can extend from the surface 31d of the housing 312 facing the negative Z direction. It is understood that the second direction only needs to be different from the first direction; in this embodiment, the location of the metal pin 311b is not specifically limited.

[0081] Metal pin 311b can be electrically connected to one end of electronic wire 33. When connector 31 is mounted on plate 100, the other end of electronic wire 33 can be soldered to the motherboard of plate 100 to achieve electrical connection between electronic wire 33 and motherboard.

[0082] Specifically, continue to refer to Figure 4A In some embodiments, the electronic wire 33 may include a wire core 332 and an insulating layer 331, wherein the insulating layer 331 may cover the wire core 332. The wire core 332 may be made of a conductive material to ensure the conductivity of the electronic wire 33. The insulating layer 331 may be made of an insulating material (e.g., polyimide or polyester film) to prevent short circuits and signal interference.

[0083] The wire core 332 can extend from one end of the electronic wire 33 for electrical connection with the metal pin 311b. In this embodiment, the wire core 332 contacts the metal pin 311b and can be soldered onto the surface of the metal pin 311b using surface mount technology (SMT). SMT is an electronic assembly technology that involves coating the surface of the metal pin 311b with solder paste, placing the wire core 332 on the solder paste, and then heating the paste to melt it and form a solder layer 301 for soldering.

[0084] In some embodiments, the wire core 332 can also be connected to the surface of the metal pin 311b using other conductive connection processes such as laser welding or ultrasonic welding. In other embodiments, the wire core 332 can also be bonded to the surface of the metal pin 311b using conductive adhesive. It is understood that the embodiments of this application do not impose specific limitations on the electrical connection method between the wire core 332 and the metal pin 311b.

[0085] It is understood that the manufacturing process of electronic wires is relatively simpler than that of flexible circuit boards, and the cost of electronic wires can be lower than that of flexible circuit boards. The connector assembly 3 provided in this application embodiment does not include a flexible circuit board 32, which can reduce the cost of the connector assembly 3. Furthermore, the electronic wire 33 is directly electrically connected to the metal pin 311b, which can ensure the reliability of the electrical connection and the stability of signal transmission, and can also reduce the impedance of signal transmission.

[0086] Furthermore, refer to Figure 4B The connection between the wire core 332 and the metal pin 311b can be covered by a covering 305. The covering 305 can fit against the surface 31c of the housing 312 to fix the connection between the wire core 332 and the metal pin 311b, and the covering 305 can also serve as insulation. For example, the covering 305 can be heat shrink tubing or acetate cloth.

[0087] In some embodiments, to secure the connection between the wire core 332 and the metal pin 311b, adhesive can be applied to the side of the wire core 332 facing away from the metal pin 311b in the Z direction. After the connector 31 is mounted on the plate 100, the wire core 332 can be fixed to the back cover 1 of the plate 100 by this adhesive.

[0088] Figure 5 An exemplary structure of connector 31 is shown. Figure 5 In the example shown, with the metal pin 311b located on the side of the housing 312 facing the negative X direction, the structure of the connector 31 can be referenced. Figure 5 .
