Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a Type-C connector and an electronic device. Background Art

[0002] In the connector structure, it is usually necessary to weld surface-mounted electronic components between pins to achieve the required circuit functions. However, when fixing electronic components by welding, during the welding process, there is a problem that the reliability and stability of the electronic components are reduced due to high temperature, which affects the reliability and stability of the connector during use.

[0003] Taking the Type-C connector as an example, the Type-C connector, as an input / output interface, is widely used in terminal devices such as mobile phones and tablet computers. The Type-C connector usually has a parallel-to-ground resistor between the GND pin and the CC pin, and the role and status of the device are detected through the CC pin. For a Type-C fast charging 6-pin USB connector, the CC pin has a CC1 pin and a CC2 pin, and the parallel resistor configuration on the CC1 pin and the CC2 pin helps the host to identify the insertion direction of the connector.

[0004] Traditional Type-C connectors usually require an additional PCBA small board, with a relatively complex process structure and high cost. Due to the presence of a height difference on the top surface between the GND pin and the CC pin and the connector, a solution of directly welding a discrete SMT small resistor device between the GND pin and the CC pin is provided. Although this structural solution is relatively simple and has a relatively low cost compared to the traditional method, in this structural method, due to the narrow internal space of the connector, there are problems with the reliability and stability of the resistor device welding, which affects the use reliability and stability of the connector.

Detailed Description of the Embodiment

[0024] The present utility model will be further described in detail below with reference to the drawings and specific embodiments, and the scope of implementation of the present utility model is not limited thereto.

[0025] As Figures 1 to 4 shown, a connector described in this embodiment includes a base 1 made of insulating material. The base 1 is provided with a connecting portion 11, and at least one first conductive terminal 2 and at least one second conductive terminal 3 are embedded in the base 1. One end of the first conductive terminal 2 and one end of the second conductive terminal 3 both extend to the connecting portion 11. The upper surfaces of the first conductive terminal 2 and the second conductive terminal 3 are both flush with the upper surface of the connecting portion 11. A connecting groove 12 is recessed at the position between the first conductive terminal 2 and the second conductive terminal 3 on the connecting portion 11. An electronic component 4 formed by functional paste is provided in the connecting groove 12, and both ends of the electronic component 4 are electrically connected to the first conductive terminal 2 and the second conductive terminal 3.

[0026] In this embodiment, by setting the upper surfaces of the first conductive terminal 2 and the second conductive terminal 3 to be flush with the upper surface of the connecting portion 11, the height difference between the conductive terminals and the connecting portion 11 is eliminated. At the same time, a connecting groove 12 is provided between the first conductive terminal 2 and the second conductive terminal 3, so that the required electronic component 4 is formed by a functional paste in the connecting groove 12, realizing the circuit function of the connector, thus avoiding the reliability and stability problems caused by SMT soldering, improving the reliability and stability of the connector, and facilitating the reduction of manufacturing costs; moreover, the parameter values of the electronic component 4 formed by the functional paste are easy to control.

[0027] During specific use, by controlling the composition of the functional paste and the width, depth, and shape of the connecting groove 12, the electronic component 4 with the required parameter values can be achieved according to the actual use requirements such as the use environment and use scenario, and the structure is flexibly used.

[0028] In this embodiment, the functional paste can be a resistor paste, a capacitor paste, or an inductor paste, and the electronic component 4 is a resistor device formed by a resistor paste, a capacitor device formed by a capacitor paste, or an inductor device formed by an inductor paste; the electronic component 4 is connected in series or in parallel between the first conductive terminal 2 and the second conductive terminal 3, and according to the actual application requirements, the electronic component 4 can be connected in series or in parallel between the two conductive terminals.

[0029] As Figure 1 and Figure 3 shown, for a connector described in this embodiment, in some embodiments, the upper surface of the electronic component 4 is flush with the upper surfaces of the first conductive terminal 2 and the second conductive terminal 3. With such a setting, compared with the existing method of separately soldering discrete SMT small electronic components 4, in this embodiment, the electronic component 4 is more reliably fixed on the connecting portion 11, and the structural reliability and stability are higher.

[0030] For a connector described in this embodiment, in some embodiments, the electronic component 4 is made by dispensing or screen printing. In this embodiment, by eliminating the height difference between the conductive terminals and the connecting portion 11, and at the same time providing a connecting groove 12 between the first conductive terminal 2 and the second conductive terminal 3, the functional paste can be placed in the connecting groove 12 in the narrow space inside the connector by dispensing or screen printing, and the functional paste is cured and formed into the electronic component 4 in the connecting groove 12, making the connection between the electronic component 4 and the first conductive terminal 2 and the second conductive terminal 3 more firm, not easy to fall off, and the parameter values of the electronic component 4 formed by the functional paste are easy to control.

[0031] To facilitate the explanation of this embodiment, the Type-C connector is taken as an example for detailed description.

[0032] When the Type-C connector is actually applied, a third conductive terminal 6 is provided between the first conductive terminal 2 and the second conductive terminal 3 on the base 1. The first conductive terminal 2 is a GND conductive terminal, the second conductive terminal 3 is a CC conductive terminal, and the third conductive terminal 6 is a VBUS conductive terminal. When the GND conductive terminal, the CC conductive terminal, and the VBUS conductive terminal are installed on the connecting portion 11, the top surfaces of the GND conductive terminal, the CC conductive terminal, the VBUS conductive terminal, and the connecting portion 11 form a flat plane, so that the subsequent production template can be flatly attached to the top surface of the connecting portion 11 to perform functional paste dispensing or screen printing into the connecting groove 12.

[0033] In this embodiment, the functional paste is a resistor paste, and the electronic component 4 is a resistor device formed by the resistor paste.

The two second conductive terminals 3 are located between the two first conductive terminals 2, and the electronic component 4 is connected between each first conductive terminal 2 and the adjacent second conductive terminal 3. Specifically, the number of the third conductive terminals 6 is also set to two; one ends of the two GND conductive terminals far from the electronic component 4 are electrically connected together, the two second conductive terminals 3 are respectively a CC1 conductive terminal and a CC2 conductive terminal, and one ends of the two VBUS conductive terminals close to the electronic component 4 are electrically connected together, thus forming a Type-C fast charging 6-pin USB connector.

The plugging portion 13 is provided on one side of the fixing portion 14, and the connecting portion 11 is provided on the other side of the fixing portion 14; the other ends of the first conductive terminal 2 and the second conductive terminal 3 extend to the plugging portion 13, and both the first conductive terminal 2 and the second conductive terminal 3 are partially exposed on the upper and lower surfaces of the plugging portion 13.

[0036] As Figures 1 to 3 shown, in this embodiment, the fixing portion 14 is sleeved with a housing 5, and the housing 5 covers the outer periphery of the plugging portion 13. Specifically, the housing 5 is made of a metal material to ensure the stability of the signal transmission of the conductive terminal.

[0037] As Figure 2As shown in the figure, in this embodiment, the housing 5 is provided with a first snap structure 51, and the base 1 is provided with a second snap structure 15 for snap-connecting with the first snap structure 51. By providing the first snap structure 51 and the second snap structure 15 for snap-connection in this embodiment, the connection between the housing 5 and the base 1 is made more firm.

[0038] As Figure 2 shown in the figure, in this embodiment, the first snap structure 51 is a snap hole, the second snap structure 15 is a snap ear, and the snap ear is snapped into the snap hole. By the cooperation of the snap hole and the snap ear in this embodiment, the assembly of the base 1 and the housing 5 is made more convenient and firm.

[0039] In this embodiment, the housing 5 extends with a connecting ear 52, the snap hole is arranged on the connecting ear 52, the housing 5 is provided with a receiving groove 16, the snap ear is arranged in the receiving groove 16, and the connecting ear 52 is received in the receiving groove 16. By providing the cooperation of the receiving groove 16 and the connecting ear 52 in this embodiment, the connection between the housing 5 and the base 1 is made more tight and the structure is more compact.

[0040] Of course, it is also possible to set the first snap structure 51 as a snap ear and the second snap structure 15 as a snap hole; it can be set automatically according to actual design needs.

[0041] As Figures 1 to 4 shown in the figure, in this embodiment, the fixing part 14 of the base 1 is provided with a limiting part 17 to limit the installation position of the housing 5 through the limiting part 17.

[0042] As Figure 2 and Figure 4 shown in the figure, in this embodiment, clip pieces 7 are arranged on both sides of the plug-in part 13 of the base 1 so as to provide an anti-pulling-off effect for the plug-in part 13 after the plug-in part 13 is inserted.

[0043] In this embodiment, a protective glue can also be covered on the surface of the electronic component 4 to meet the use requirements of a more demanding use environment.
