DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the embodiments and drawings. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0027] Example

[0028] See also Figure 1-Figure 5 , a high-power FPC connector, comprising:

[0029] A plug housing 1 and a socket housing 2 that can be plugged into and matched with each other;

[0030] A jack assembly 3 and a jack insulator 4 are installed in the plug housing 1, one end of the jack assembly 3 is fixed in the jack insulator 4, and the other end of the jack assembly 3 faces the socket housing 2;

[0031] A pin assembly 5 and a pin insulator 6 are installed in the socket housing 2, one end of the pin assembly 5 is fixed in the pin insulator 6, and the other end of the pin assembly 5 is used for mating with the socket assembly 3;

[0032] Also includes:

[0033] A first flat wire 7, one end of which extends into the jack insulator 4, and the first flat wire 7 is electrically connected to the jack component 3 located in the jack insulator 4 by ultrasonic welding;

[0034] The second flat wire 8 has one end extending into the pin insulator 6, and the second flat wire 8 is electrically connected to the pin assembly 5 located in the pin insulator 6 by ultrasonic welding.

[0035] In this embodiment, the jack insulator 4 and the jack assembly 3 in the plug housing 1 can be assembled by inserting plastic pressing molding technology; similarly, the pin insulator 6 and the pin assembly 5 in the socket housing 2 can be assembled by inserting plastic pressing molding technology. The jack assembly 3 and the first flat wire 7, and the pin assembly 5 and the second flat wire 8 are welded by ultrasonic welding, which improves the connection quality between the contact and the corresponding flat wire, realizes the transmission function under high voltage and high power, and can ensure the reliability of the high-power FPC connector under high temperature, high voltage, high current and other environments.

[0036] In this embodiment, the first flat wire 7 and the second flat wire 8 are both provided with two layers of flat conductors, and an insulating layer is provided between the two layers of flat conductors. Since the flat wire is a double-layer flat conductor structure, an insulating layer is sandwiched between the two layers of conductors, when welding, two rows of conductors can be welded to the corresponding contact body of the pin assembly 5 or the socket assembly 3 at the same time, so as to meet the reliable transmission of signals.

[0037] In this embodiment, the pin assembly 5 and the jack assembly 3 are respectively provided with a slot 9 for inserting the first flat wire 7 or the second flat wire 8 at the tail welding position, and the flat conductors on both sides of the first flat wire 7 and the second flat wire 8 are fixed to the inner wall of the slot 9 by ultrasonic welding. The first flat wire 7 and the second flat wire 8 are welded in the corresponding slot 9 by ultrasonic welding. During the welding process, the inner wall structure of the slot 9 and the contact position of the flat conductor can cooperate with the static pressure and elastic vibration energy to convert the mechanical kinetic energy into the friction work deformation energy and the resulting temperature rise between the workpieces, so that the workpieces can achieve stable electrical connection in the solid state. In this embodiment, ultrasonic welding is achieved through the flattened design of the pin or jack contact to ensure the welding quality, which not only realizes the signal transmission between the connector and the cable in a narrow space, but also further improves the reliability of the high-power FPC connector in high temperature, high voltage, high current and other environments, and can also save the internal space of the corresponding shell.

[0038] In this embodiment, flanges 10 are provided on the outer walls of the plug housing 1 and the outer walls of the socket housing 2, respectively, and screws 11 and threaded sleeves 12 that cooperate with each other are provided between the two flanges 10 to fix the plug housing 1 and the socket housing 2 after plugging. A spring washer is provided between the head of the screw 11 and the corresponding flange 10, and the provision of the spring washer can ensure that the socket housing 2 and the pin housing are tightly matched, and are not prone to loosening or displacement, thereby further ensuring reliable signal transmission.

[0039] In this embodiment, a potting groove 13 is provided at the inner wall position of the plug housing 1 corresponding to the jack insulator 4, and a potting groove 13 is provided at the inner wall position of the socket housing 2 corresponding to the pin insulator 6. The potting groove 13 is used to fill the potting glue so as to adhere and fix the jack insulator 4 or the pin insulator 6 to the corresponding inner wall of the housing, which can not only meet the temperature requirement of 300°C for long-term application, but also meet the waterproof sealing requirement of high-power FPC connector products.

[0040] In this embodiment, an interface seal 14 is provided in the socket housing 2 on the side of the pin insulator 6 facing the plug housing 1. The provision of the interface seal 14 can increase the creepage distance and improve the high voltage resistance performance of the high-power FPC connector product.

[0041] A sealing ring 15 is also provided at the contact point between the socket housing 2 and the pin housing, which can further improve the waterproof performance of the high-power FPC connector.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
