Description
Technical Field
[0001] The utility model belongs to the technical field of connectors, and particularly relates to a high-power inter-board connection structure. Background Art
[0002] At present, both electronic components and electromechanical components have electrical contacts, and the electrical connection between two discrete contacts is called interconnection. Electronic devices must be interconnected according to the circuit schematic diagram to achieve the intended functions. The common interconnection methods are wire welding and connector connection.
[0003] The advantages of the wire welding connection method are simplicity, low cost, and high reliability, and it can avoid faults caused by poor contact; however, the disadvantages are that it is not convenient enough for interchange and maintenance; this method is generally applicable to the case where the external leads of the components are few.
[0004] In relatively complex instrument and equipment, for example, when interconnecting the printed circuit boards of the motor drive module, the connector connection methods such as wires, flexible cables, and standard pins are often used for interconnection. However, this interconnection method can only be applied to small-power motor drive modules. The main reason is that it is limited by the wire diameter, pin diameter, and material of the wires, flexible cables, and standard pins, and cannot pass large currents. Therefore, the application of this connection method in the field of high-power motor drive modules is limited. Summary of the Invention
[0005] The utility model aims to solve the above problems and provides a high-power inter-board connection structure that can achieve the interconnection between the circuit boards of high-power motor drive modules.
[0006] The high-power inter-board connection structure of the utility model includes a body;
[0007] The body includes a first connector and a second connector;
[0008] A groove is provided on the first connector; the two side walls of the groove form the first protrusion of the body; the longitudinal section of the first connector is concave-shaped;
[0009] The second connector is fixedly connected to the aforementioned first connector;
[0010] The second connector is arranged on the side wall or the bottom wall of the aforementioned first connector to form the second protrusion of the body. When connecting high-power boards, the groove is used to connect PIN pins and store solder during welding; the first protrusion is used to connect one high-power board, and the second protrusion is used to connect another high-power board to achieve the reliable connection of two high-power boards.
[0011] Furthermore, for the high-power inter-board connection structure of the present utility model, the tops of the first protrusion and / or the second protrusion are set as curved surfaces. Setting the tops of the first protrusion and the second protrusion as curved surfaces facilitates the connection of the connection structure of the present utility model with the circuit board. At the same time, it can effectively avoid the situation of scratching personnel that occurs in the case of manual soldering of the connection structure, improving the aesthetics and safety.
[0012] Furthermore, for the high-power inter-board connection structure of the present utility model, the inner surface of the groove is set as a curved surface.
[0013] Furthermore still, for the high-power inter-board connection structure of the present utility model, the longitudinal section of the groove is U-shaped. Setting the longitudinal section of the groove as U-shaped can make the surface of the PIN needle fit more closely with the groove when connecting the PIN needle, improving the conductive connection efficiency.
[0014] Furthermore still, for the high-power inter-board connection structure of the present utility model, a gold-plated film is provided on the surface of the body; by performing gold-plating treatment on the surface of the body to make a gold-plated film adhere to its surface, the conductive performance of the connection structure can be effectively improved, and the connection efficiency between high-power boards can be increased.
[0015] For the high-power inter-board connection structure of the present utility model, a groove is formed through the first connecting member to form a first protrusion for connecting high-power boards, and the groove is used for the fixation and connection of PIN needles; the second connecting member is fixedly connected to the first connecting member and forms a second protrusion for connecting another high-power board, reliably realizing the connection between high-power boards. The structure is simple, easy to operate and use, and is suitable for popularization and application. Description of the Drawings
