Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronics, in particular to a connector and an electronic device. BACKGROUND

[0002] In daily life, many products are provided with connectors. A connector refers to a device that bridges two conductors on a circuit to enable current or signals to flow from one conductor to another. A male connector is usually required to be plugged with a female connector to realize the conduction of the circuit. Electronic devices are generally provided with male connectors, such as Type-C connectors.

[0003] In related technologies, a Type-C connector generally has ground terminals, power terminals and a large number of signal terminals. However, since the large number of signal terminals will occupy most of the space in the connector, the size of the ground terminals and the power terminals is limited, that is, the area of the ground terminals and the power terminals for contacting the mating side connector is small. As a result, the current carrying capacity of the connector is low, and thus the connector cannot meet the high power demand of some electronic devices. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the present application provides a connector and an electronic device, which improves the current carrying capacity of the connector and can meet the high power demand of the electronic device.

[0005] In one aspect, the present application provides a connector, which comprises a housing, a seat body and a terminal assembly.

[0008] The terminal assembly comprises at least two first terminals arranged side by side on the seat body, and each first terminal comprises a first contact portion, a first welding portion, a first bending portion, a second contact portion and a second welding portion. The first bending portion is connected between the first contact portion and the second contact portion, and the first contact portion and the second contact portion are exposed on the first surface and the second surface respectively. The first welding portion is connected with the first contact portion, and the second welding portion is connected with the second contact portion.

[0011] Optionally, an end of the first contact portion away from the plug-in interface is bent towards the second contact portion and connected with the first welding portion.

[0012] An end of the second contact portion away from the plug-in interface is bent towards the first contact portion and connected with the second welding portion.

[0013] Optionally, at least one of the first welding portion and the second welding portion is bent away from a center of the seat body.

[0014] Optionally, the first contact portion and the second contact portion are opposite to each other in a thickness direction of the seat body, and the first welding portion and the second welding portion are opposite to each other in the thickness direction of the seat body, wherein a welding area is formed between the first welding portion and the second welding portion.

[0015] Optionally, the terminal assembly further comprises a second terminal arranged side by side with the first terminal on the seat body, the second terminal comprising a third contact portion, a third welding portion, a second bending portion and a fourth contact portion, the second bending portion being connected between the third contact portion and the fourth contact portion, the third contact portion and the fourth contact portion being exposed on the first surface and the second surface respectively, and the third welding portion being connected with the third contact portion or the fourth contact portion.

[0016] Optionally, the terminal assembly comprises four first terminals and one second terminal, two of the first terminals being ground terminals, the other two of the first terminals being power supply terminals, and the second terminal being a signal terminal.

[0017] The two ground terminals are symmetrically distributed about the signal terminal, and the two power supply terminals are symmetrically distributed about the signal terminal.

[0018] Optionally, a width of the first terminal is greater than a width of the second terminal.

[0019] In another aspect, an electronic device is also provided, comprising a circuit board and a connector according to any one of the embodiments of the present application, a welding end of the terminal assembly penetrating through an end of the seat body away from the plug-in interface and being connected with the circuit board.

[0020] The connector provided in the embodiments of the present application comprises a housing, a seat body and a plurality of terminal assemblies.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative work fall within the scope of protection of the present application.

[0034] Unless otherwise defined, all the technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.

[0035] In order to make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below in combination with the drawings.

[0036] In combination with Figure 1 , Figure 2 and Figure 3 , the embodiments of the present application provide a connector, which comprises a shell 100, a seat body 200 and a terminal assembly 300.

[0037] The shell 100 is provided with a plug cavity 110, which has a plug interface 111 in the plug-pull direction, so that a mating side connector can be inserted into the plug cavity 110 along the plug-pull direction to realize plug connection with the connector provided by the embodiments of the present application, thereby realizing the corresponding functions.

[0038] The seat body 200 is located in the insertion cavity 110, and the seat body 200 comprises a first surface 210 and a second surface 220 extending along the insertion and extraction direction, and the first surface 210 and the second surface 220 are opposite to each other. The terminal assembly 300 comprises at least two first terminals 310 arranged side by side on the seat body 200, and each first terminal 310 comprises a first contact portion 311, a first welding portion 312, a first bending portion 313, a second contact portion 314 and a second welding portion 315, the first bending portion 313 is connected between the first contact portion 311 and the second contact portion 314, the first contact portion 311 and the second contact portion 314 are exposed on the first surface 210 and the second surface 220 respectively, the first welding portion 312 is connected with the first contact portion 311, and the second welding portion 315 is connected with the second contact portion 314. It should be noted that the terminal assembly 300 and the seat body 200 can be integrally formed by injection molding. It can be understood that the part of the first contact portion 311 and the second contact portion 314 exposed from the first surface 210 and the second surface 220 respectively can be electrically connected with the corresponding terminals in the connector on the opposite side. The first contact portion 311, the first welding portion 312, the first bending portion 313, the second contact portion 314 and the second welding portion 315 can be integrally formed, for example, the first terminal 310 can be formed by stamping a reverse bending structure, so as to not only facilitate the processing of the terminal assembly 300, thereby improving the manufacturing efficiency of the terminal assembly 300, but also reduce the manufacturing cost of the terminal assembly 300.

[0039] Since the first bending portion 313 is equivalent to connecting the first contact portion 311 and the second contact portion 314 in parallel, the impedance of the first terminal 310 is small, thereby increasing the current carrying capacity of the terminal assembly 300, that is, increasing the current carrying capacity of the connector, so that the connector can meet the high power demand of the electronic device. At the same time, since each first terminal 310 has two welding portions, the first terminal 310 and the circuit board (not shown in the figure) can be more stably welded together, thereby improving the reliability of the terminal assembly 300.

[0040] The above will be described in detail below with reference to the accompanying drawings. Figures 1 to 6 The details and effects of the connector provided by the embodiments of the present application will be described in more detail.

[0041] As Figure 2As shown, in some embodiments, the first contact portion 311 and the second contact portion 314 are opposite to each other in the thickness direction of the seat body 200, and the first welding portion 312 and the second welding portion 315 are arranged side by side in the width direction of the seat body 200. It should be noted that any two of the thickness direction, the width direction and the plugging direction of the seat body 200 are perpendicular to each other. The first welding portion 312 and the second welding portion 315 are adapted to be welded together with the circuit board. The first contact portion 311 and the second contact portion 314 are opposite to each other in the thickness direction of the seat body 200, for example, the first contact portion 311 and the second contact portion 314 can be arranged symmetrically about the median plane of the first bending portion 313 in the thickness direction, so that the front and back of the connector can be mated with the mating connector, which is more convenient for users to use. Figure 2 As shown, in some embodiments, the width of the first welding portion 312 is smaller than the width of the first contact portion 311, and the width of the second welding portion 315 is smaller than the width of the second contact portion 314. In this way, when the first terminal 310 is welded to the circuit board, enough welding space can be ensured for the first welding portion 312 and the second welding portion 315.

[0042] As shown, in some embodiments, the end of the first contact portion 311 away from the plugging end 111 is bent towards the second contact portion 314 and connected with the first welding portion 312. The end of the second contact portion 314 away from the plugging end 111 is bent towards the first contact portion 311 and connected with the second welding portion 315. In this way, the first welding portion 312 and the second welding portion 315 can be located in the same plane, so that the first welding portion 312 and the second welding portion 315 can be welded together with the same surface of the circuit board. Figure 2 As shown, in some embodiments, at least one of the first welding portion 312 and the second welding portion 315 is bent away from the center of the seat body 200. In this way, the distance between the first welding portion 312 and the second welding portion 315 can be ensured not to be too close, which is convenient for welding the first welding portion 312 and the second welding portion 315.

[0043] Figure 2 As shown, in some embodiments, at least one of the first welding portion 312 and the second welding portion 315 is bent away from the center of the seat body 200. In this way, the distance between the first welding portion 312 and the second welding portion 315 can be ensured not to be too close, which is convenient for welding the first welding portion 312 and the second welding portion 315.

[0044] As shown, in some embodiments, at least one of the first welding portion 312 and the second welding portion 315 is bent away from the center of the seat body 200. In this way, the distance between the first welding portion 312 and the second welding portion 315 can be ensured not to be too close, which is convenient for welding the first welding portion 312 and the second welding portion 315. Figure 4 ​As shown, in some embodiments, the first contact portion 311 and the second contact portion 314 are opposite to each other in the thickness direction of the seat body 200, and the first welding portion 312 and the second welding portion 315 are opposite to each other in the thickness direction of the seat body 200, and a welding area 316 is formed between the first welding portion 312 and the second welding portion 315. It should be noted that the circuit board is generally located in the welding area 316, and at this time, the first welding portion 312 and the second welding portion 315 can be welded on the opposite sides of the circuit board, respectively. In this way, it is more convenient to weld the first welding portion 312 and the second welding portion 315 in a limited space, and the welding efficiency can be improved. At the same time, since the first welding portion 312 and the second welding portion 315 are located on different sides of the circuit board, the widths of the first welding portion 312 and the second welding portion 315 can be consistent with the widths of the first contact portion 311 and the second contact portion 314, respectively, so as to further reduce the impedance of the first terminal 310, and thereby increase the current-carrying capacity of the terminal assembly 300, that is, increase the current-carrying capacity of the connector, so that the connector can meet the high-power demand of the electronic device.

[0045] In combination Figure 1 and Figure 5 As shown, in some embodiments, the terminal assembly 300 further includes a second terminal 320 arranged side by side with the first terminal 310 on the seat body 200, the second terminal 320 includes a third contact portion 321, a third welding portion 322, a second bending portion 323 and a fourth contact portion 324, the second bending portion 323 is connected between the third contact portion 321 and the fourth contact portion 324, the third contact portion 321 and the fourth contact portion 324 are exposed on the first surface 210 and the second surface 220, respectively, and the third welding portion 322 is connected to the third contact portion 321 or the fourth contact portion 324. It should be noted that the third contact portion 321, the third welding portion 322, the second bending portion 323 and the fourth contact portion 324 can be an integrally formed structure, for example, the second terminal 320 can be formed by stamping a reverse bending structure, so as to not only facilitate the processing of the terminal assembly 300 to improve the manufacturing efficiency of the terminal assembly 300, but also reduce the manufacturing cost of the terminal assembly 300.

[0046] As Figure 1 and Figure 6As shown, in some embodiments, the terminal assembly 300 includes four first terminals 310 and one second terminal 320, two of the first terminals 310 are ground terminals, the other two of the first terminals 310 are power terminals, and the second terminal 320 is a signal terminal. The two ground terminals are symmetrically distributed about the signal terminal, and the two power terminals are symmetrically distributed about the signal terminal. It should be understood that when the connector is plugged with a mating-side connector, the charging function can be achieved. It should be noted that the distance between the ground terminals and the signal terminal is greater than the distance between the power terminals and the signal terminal. Since the two ground terminals and the two power terminals are symmetrically distributed, the front and back of the connector can be mated with the mating-side connector, which is more convenient for users to use. In addition, since the connector only includes one second terminal 320, the first terminals 310 can occupy a larger space in the connector, that is, the first contact part 311 and the second contact part 314 of the first terminal 310 respectively expose a larger area from the first surface 210 and the second surface 220, thereby improving the current-carrying capacity of the first terminal 310, so that the connector can meet the high-power charging demand of the electronic device. For example, the current-carrying capacity of the connector provided in the embodiments of the present application can reach 25A. Moreover, since the number of signal terminals is small, the size of the connector can be reduced, for example, the width of the seat body 200 in the connector can be 5.7mm, and the thickness can be 2mm. In this way, the space occupied by the connector in the electronic device can be reduced, and other devices in the electronic device can be reasonably arranged, thereby improving the space utilization in the electronic device.

[0047] As Figure 6 shown, in some embodiments, the width of the first terminal 310 is greater than the width of the second terminal 320. In this way, the first terminal 310 can have a larger width, ensuring that the first contact part 311 and the second contact part 314 respectively expose a larger area from the first surface 210 and the second surface 220, thereby improving the current-carrying capacity of the connector and meeting the high-power charging demand of the electronic device installed with the connector.

[0048] In another aspect, the embodiments of the present application also provide an electronic device, which comprises a circuit board and the connector of any one of the embodiments of the present application. The soldering end of the terminal assembly 300 penetrates the end of the seat 200 away from the plug interface 111 and is connected to the circuit board. It should be noted that the connector installed in the electronic device is the same as the connector of any one of the embodiments of the present application in terms of composition and function, and thus the embodiments of the present application will not be described here again. The circuit board can be a printed circuit board or a flexible circuit board. It should be understood that, since the connector has high current-carrying capacity, the electronic device installed with the connector can meet the high-power charging requirement. At the same time, the connector has small size, so the connector does not occupy a large space in the electronic device, that is, the connector effectively saves the internal space of the electronic device and improves the space utilization rate in the electronic device.

[0049] Other embodiments of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. The specification and examples given are exemplary only. It is intended to encompass all alternatives, modifications and equivalents thereof within the scope of the present application.
